GAS EMERGENCY AND
SERVICE HANDBOOK
FOREWORD
The Gas Emergency and Service Handbook (GESH) establishes the service policy of Avista Utilities. The policies and procedures contained herein are an integral part of Avista Utilities Operating & Maintenance Plan as required by 49 CFR, Part §192.605 and as required by state codes. This handbook supersedes the previous Gas Service Handbook and also supersedes any previous documents pertaining to the policies contained herein.
The most current issues of the following publications or manuals are hereby incorporated by reference: The Avista Utilities Gas Standards Manual (GSM), Avista Gas Construction Specifications, NFPA No. 54, CABO One & Two Family Dwelling Code Book, International Building Code, International Residential Code, International Fuel Gas Code, Transmission Integrity Management Program (TIMP), Distribution Integrity Management Plan (DIMP), Anti-Drug and Alcohol Misuse Prevention Plan, Control Room Management Plan, Public Awareness Program, Manufacturer’s Operating Instructions Manual for Gas Operations, Natural Gas Quality Assurance / Quality Control Program, and the Avista Incident Prevention Manual.
Operations managers or personnel designated by them are responsible for adherence to the policies and procedures contained in this handbook for proper installation and maintenance of Avista’s natural gas facilities. This handbook is made available to the appropriate individuals through a hardcopy and/or via the company intranet per §192.615(b)(1).
The primary job classification addressed in this handbook is the Journeyman Gas Service Person. Many of the procedures in this handbook may be performed by other qualified gas employees at certain times. Employees other than service persons performing these procedures shall be properly trained and qualified.
Within the GESH a "shall" or "must" is used to indicate that a provision is mandatory.
•Written variances to the GESH (for “shall/must” statements) may be granted except insituations where the provision is mandatory in state/federal code in which case thevariance will not be granted.
•A request to not follow a “shall” or “must” starts with the respective local Avistamanager/designated Avista representative giving their approval.
•The request will then be forwarded to the appropriate responsible reviewer as delineatedin Specification 1.4, Table 1.
•These variances should be documented in a manner that is retrievable for futurereference.
Within the GESH a "should" is used to indicate that the provision is not mandatory; but is the preferred method and recommended as a good practice.
•Not following “should” statements in the GESH, does not require receiving a written orverbal variance unless the local Operations Manager requires such.
•These variances should be documented in a manner that is retrievable for future
reference.
Responsibility for maintaining the accuracy of this manual is the function of the Gas Compliance Department. Suggestions for improvement are always welcome. Please forward all suggestions
or observations to Randy Bareither in the Gas Compliance Department via the “Recommended Changes” form from this manual or scan and send through email to him at
[e-mail].

Management Commitment and Support
Avista’s goal is to protect the health and safety of its employees and the communities in which we operate. Avista’s management is committed to supporting the GESH and the corresponding activities which seek to recognize and mitigate threats to Avista’s pipeline facilities. Avista’s leadership provides this continuous support through the implementation of a Pipeline Safety Management System ((P)SMS).
Avista’s (P)SMS provides an overarching safety strategy and framework designed to enhance the effectiveness of risk management and enable continuous improvement of pipeline safety performance. The GESH is evaluated and improved in accordance with the (P)SMS framework outlined in Avista’s Pipeline Safety Management Plan. Avista’s (P)SMS connects the GESH with the other plans, programs, and emergency response activities to ensure the continued safe operation of the gas system.
Pipeline Safety Management System Principles
Avista’s (P)SMS is based on industry guidance provided in the American Petroleum Institute (API) Recommended Practice 1173 (RP 1173) “Pipeline Safety Management Systems.” RP 1173 details the components of a (P)SMS using 10 Essential Elements and the Plan, Do, Check, Act model (PDCA.) Avista has modified the model to replace the Act step with Adjust to align with our enterprise Safety Management system. The graphic below illustrates, each of the 10 Elements embedded into the PDCA circle showing the cyclical nature of PDCA and the continuous improvement philosophy of the (P)SMS. Each cycle through PDCA produces opportunities for improvement of our defenses and controls, making our system safer over time. The components of the Plan-Do-Check-Adjust cycle are as follows:
Plan: This step entails establishing the objectives and processes necessary to deliver results in accordance with the organization’s policies and the expected goals. By establishing output expectations, the completeness and accuracy of the process is also a part of the targeted improvement.
Do: This step is the execution of the plan designed in the previous step.
Check: This step entails the review of the results compared with established objectives. Comparing those results to the expected goals to ascertain any differences; looking for deviation in implementation from the plan.
Adjust: This step is where a pipeline operator takes actions to continuously improve process performance, including corrective actions on significant differences between actual and planned results, analyzes the differences to determine their root causes, and determines where to apply changes that will include improvement of the process or product.

DISPATCHING
GAS EMERGENCY AND
SERVICE HANDBOOK

SECTION 1 RECEIVING AND DISPATCHING EMERGENCY SERVICE REQUESTS GENERAL Avista Utilities customers shall have communication access to qualified, trained gas personnel who shall receive, prioritize, and dispatch incoming service requests. Communication access for orders of a priority
or emergency nature shall be provided 24 hours per day, 365 days per year. The Gas Control Room shall take action and respond to emergencies in accordance with the Gas Control Room Management Plan, Roles and Responsibilities, Section 2.
Initial Reporting of Emergencies Initial emergency notifications should be made through the Avista Contact Center at 800-227-9187 without regard to whether the individual making notification is an Avista employee, customer, or third
party. Initial calls should not be made directly to the Gas Control Room however, subsequent calls from Avista First Responders to correct or modify initial information received from the Contact Center, or to request an “On-Site Repair” order to electronically capture Avista side leak information are acceptable and may result in the cancelling and / or the creating of a trouble order by the Gas Controller. PRIORITY OF SERVICE REQUESTS Priority 1 – Emergency Requests
The following types of requests shall be dispatched immediately to the next available service person for
immediate response: The priority in which several concurrent emergency requests are dispatched shall be left to the discretion of a trained and qualified gas controller. Consideration shall be given first to protecting life, then property in making such decisions. To help aid in the decision making, a category was created for Priority 1 requests; Category 1 takes higher priority than a Category 2. At times there may be a need for Control Room Operators to prioritize between two or more service requests of identical Priority and Category occurring simultaneously. On these rare occasions, the Control Room Operator with help from the Avista First Responder as applicable, should, to the best of
their ability, prioritize based on their professional judgment and the available known information. Consulting the local operations manager or on-call supervisor is an additional resource that can be consulted to help prioritize in such an unlikely situation.

Emergency or blowing gas orders taken by the Contact Center shall be immediately entered into the computerized dispatch system. If the system is unavailable for any reason, an email order or paper order shall be generated and sent to the Gas Control for purposes of confirmation and documentation. Priority 1 Orders that have been dispatched through the computerized dispatching system should be reviewed by the Controller for acknowledgment by the Serviceman as soon as practical to ensure such orders don’t get overlooked while taking care of routine service work. Priority 2 Requests The following types of requests shall be dispatched and worked promptly, however; a Priority 1 - Emergency Request takes precedent over a Priority 2 request:

Priority 1 and 2 Arrival Times Personnel receiving orders shall respond in accordance with the prioritization detailed above. When “Arrival” on site by the Avista First Responder exceeds the following targets, justification should be properly documented on the work order.
Response Prioritization Max “Arrival” Target
Service Requests The following types of orders shall be dispatched on an appointment or "as workload permits” basis:
• Meter installations.
• No heat calls.
• Non-emergency appliance service requests.
• Check meter for leaning, vibrations, and noise. Avista Utilities in Oregon shall follow the same service request priority timetable, with the following exceptions: Turn-on orders for new customers shall be completed no later than the next working day unless otherwise requested by the customer. Out of Area Odor Calls
As a general rule, Avista Gas First Responders will not respond to odor / CO calls in areas where we are
known to not supply natural gas (i.e., areas not in Avista’s Gas Service territory). An exception where the
order could be dispatched to an Avista Gas First Responder would be if Police or Fire personnel are
requesting Avista’s assistance, or a customer reports a gas / CO odor and Avista is unable to contact the
customer to guide them to their local support resources.
HANDLING AND EVALUATING EMERGENCY CALLS
Information to Obtain The Avista employee receiving a request of a priority or emergency nature shall verify that there is a gas service or meter at the address or location in question. The following information shall be obtained and recorded on the appropriate gas operating order:
• Date call received
• Time call received
• Customer's name and name of person making the call (if different from customer)
• Street address, city, and/or the location of the emergency
• Type of building or structure, i.e., residence, business, multistory, etc.

• Telephone number where customer or caller can be reached
• Detailed information on the nature of the emergency or priority, including relative, strength of odor, if anything is on fire, if a sound is detected, if anything is visually out of order, etc.
• Initials or name of the gas employee receiving the request. Instructions or advice given to the customer shall be recorded on the appropriate gas operating order.

Emergency Instructions
If deemed appropriate by the gas employee handling the emergency or priority call, the caller is to be given the following instructions as applicable: Gas Escaping Outside - Request caller to:
• Call 911
• Warn people to keep clear of the affected area
• Keep sources of ignition away from the affected area Gas Escaping Inside - Request caller to:
• Evacuate the building and warn others in the building to evacuate immediately.
• Call 911
• Warn the caller not to operate any electrical switches (light, TV, doorbell, garage door openers, etc.), and not to start the car or hang up the telephone (if calling from the house where gas is detected).
• Warn callers in business structures not to use elevators for evacuation Gas Fire Outside - Request caller to:
• Call 911
• Let the fire burn if it is not life threatening (advise that burning gas will not explode or accumulate).
• Advise caller that surrounding combustibles may be sprayed with water if in danger of igniting. (Do not suggest going close to fire to do this as radiant heat may be of very high
intensity. Encourage the caller to wait for the fire department to contain the fire.)

Gas Fire Inside - Request the caller to:
• Call 911
• Shut off the gas at the meter or the appliance (if it can be safely done)
• Evacuate the building and warn all others to evacuate immediately Carbon Monoxide (Symptomatic) - Request the caller to:
• Evacuate to an area that has fresh air
• Call 911 if symptoms or degree of illness require Notifying Emergency Services (911) For a Blowing or Uncontrolled Escaping Gas (Code 9) situation, emergency services should be called by the person making the initial report since they are presumably in the area and know the situation. The contact center is responsible for asking if emergency services have been notified and, if they haven’t yet been notified, request that the individual making the report call 911. Emergency services shall be called immediately by the on-site employee or Avista contractor whenever it is believed that such notification has not yet occurred by other entities. Some examples of such a notification would be as follows:
• Explosion or fire at or near a gas facility
• A need for medical attention
• Uncontrolled or unintentional release of a large volume of gas (at or near 3 Million Cubic Feet)
• A possible rupture of a pipeline is indicated
• Bomb threats or sabotage to gas facilities
• Natural disasters where gas facilities may be involved
• Cases of civil disorder in which gas facilities may be involved
• Any other gas related incident in which police and/or fire departments are likely to be involved or where they may be of assistance to company personnel.
A gas first responder may call 911 directly, or request that the control room contact the necessary 911 emergency call center if the situation necessitates it. Applicable 911 emergency call center numbers can be found in the Flip Chart or Zetron. Gas leak, odor, carbon monoxide, or other emergency requests shall be dispatched to a properly trained and qualified gas journeyman service person or other qualified gas employee per the current, approved call-out list. The local operations manager shall review and approve the call-out list as often as necessary to assure conformity to the policy outlined in Section 2 - Leak and Odor Investigation, “Responding Employee Qualifications”.

LEAK AND ODOR INVESTIGATION
GAS EMERGENCY AND
SERVICE HANDBOOK

SECTION 2 LEAK AND ODOR INVESTIGATION GENERAL Reports of gas odors, gas leakage, or suspected gas leak calls and symptomatic carbon monoxide odors on Avista Utilities facilities or on customer's equipment or piping shall be evaluated and dispatched to the
next available first responder for immediate response. These reports shall be responded to by a Qualified Gas First Responder 24 hours a day, 365 days per year. The Qualified Gas First Responder shall conduct a thorough investigation for leakage and shall correct hazardous leakage found on Company facilities. Hazardous leakage or hazardous conditions on customer's equipment or house piping shall be made safe. Required Information
Gas leak, odor, or carbon monoxide orders shall be issued on the appropriate gas operating order. The order shall contain the following information: customer name, phone number (mobile number if available), complete address and cross street as applicable (with apartment or unit number, as necessary), date scheduled, date and time order was taken, initials of employee receiving the call, time arrangements, and appropriate customer comments related to the order.
Completed gas leak, odor, or carbon monoxide orders shall indicate the arrival and departure times of the
first responder who is responding to the call. Conditions found and work performed shall be recorded, including the results of meter clock test or spot check, gas in air readings from combustible gas indicators,
carbon monoxide readings, etc.
Responding Employee Qualifications
Employees responding to gas leak or odor calls, carbon monoxide orders, and emergency orders shall be properly trained and qualified Journeyman Gas Service Persons. In certain cases where a Journeyman
Gas Service Person is not immediately available, a properly trained and qualified gas employee may respond provided that the employee is currently qualified on tasks associated with Company facilities as
specified by CFR 49 Part 192, 192.801, and “Operator Qualification” on tasks associated with Company facilities.
Employees performing work on Company gas facilities shall be subject to random as well as other
required drug and alcohol testing as specified by CFR 49 Part 199 and Part 40.
An employee responding to gas leak, odor, carbon monoxide, or emergency calls shall have access to a copy of this handbook, a combustible gas indicator that indicates percent gas in air readings, as well as
the appropriate tools and items required to make the situation safe for the public (e.g., fire suit, eye protection, squeeze-off tools, fire extinguisher, street valve keys, static prevention kit, and probe bar.).
Actions taken shall be documented per this policy.
This section identifies minimum procedures and actions to be taken by first responders. It is not intended to dictate the maximum action that may be taken if the situation demands it. At their discretion, first
responders have the ability to consider factors such as proximity to ignition sources, the type of leak and the volume of gas present, weather patterns, the spread of the gas, or other mitigating factors. The
employee shall act to minimize hazards to protect life, property, or the environment.

Facilities Covered This section covers aboveground and below ground facilities that exist downstream of Avista’s gas meter. These facilities may include (but are not limited to) customer piping and equipment found inside structures as well as customer-owned underground piping designed to serve outbuildings or other facilities such as swimming pools. Gas Check Prior To Entry
Qualified employees responding to reports of gas odors, gas leakage, or suspected gas leakage inside a building or structure shall first use a combustible gas indicator that visually indicates concentrations of natural gas in percentage gas-in-air readings. The combustible gas indicator shall be used initially to determine if a hazardous level of natural gas is present inside. If combustible gas indicator readings indicate high levels of CO, refer to GESH Section 3 - Carbon Monoxide (CO) Orders. A laser methane detector may also be used to check for the presence of gas but shall not be used to record gas concentration. These detectors can be used through windows and around door frames to check for gas inside rooms. They can also be used to check hard to reach areas such as high ceilings, soffit vents, crawl spaces, etc. The intent of the laser methane detector is to provide other means of checking for the presence of gas at a safe distance. Procedures Upon Entry
Concentrations of gas found to be 1 percent gas-in-air or higher in the general atmosphere inside the building or structure shall require immediate evacuation of persons in the building or structure to a safe distance. The responding employee shall also follow the procedures as outlined in GESH Section 4 - Emergency Procedures. The source of leakage shall be located and repaired. If repairs cannot be made, equipment shall be disconnected, and a hazard notice issued. The gas meter may be locked in some cases.

LEAK AND ODOR INVESTIGATION
GAS EMERGENCY AND
SERVICE HANDBOOK

External PPM Survey Whether a customer-side leak is found or not, an external ppm survey shall be completed utilizing an approved leak detection instrument or CGI unit in “ppm mode” that can detect a concentration of 50 ppm or less. Should any concentration in the “ppm mode” be found, a bar hole survey using a CGI in the “percent gas mode” is required to be used to grade and pinpoint the leak. If a percentage of gas is found
during bar holing, an outside leak and odor investigation shall be performed and documented as outlined in this section. If zero reads are found during the initial survey, no other action is required.
METER SPOT CHECK
Meter Spot Check Procedure When investigating a customer side leak or odor, the first responder shall spot check the meter. The meter should be brought up to standard at this time as well unless there are extenuating circumstances why it can’t be done. Refer to GESH Section 7 - Meter Turn-On Orders, “Bringing Meters up to Standard,” for further guidance.
A meter spot check shall be performed in cases where gas leakage on customer house piping or
equipment is suspected, but not visually confirmed, or in any of the following cases:
• When there is a gas related fire, explosion, facility failure, or other reportable incident. (Perform the test if safe and practical to do so. Obtain permission of emergency services before attempting to enter potentially unsafe structures or areas).
• Whenever a leak investigation is inconclusive, or the source of a gas odor is indeterminate.
• Whenever completing any gas turn-on order or meter install order.
• When working a High Bill Investigation (unless the complaint is determined to be the result of an obvious misread meter). Meter spot check shall be performed in the following manner: 1. Close all pilots and burners on non-automatic shutoff gas equipment. Equipment with an automatic shutoff should be tested with the pilot extinguished and the main burner valve on. Leave main appliance valves on. 2. Purge gas at outlet side of meter until the smallest test hand dial is on the upsweep. 3. Indicate the position of the test dial and reference marks. 4. Observe the test dial for the following time periods: 1/4 CFH Test Hand 2 Minutes 1/2 CFH Test Hand 2 Minutes 1 CFH Test Hand 2 Minutes 2 CFH Test Hand 5 Minutes 5 CFH Test Hand 10 Minutes 10 CFH Test Hand 10 Minutes Over 10 CFH Test Hand Use pressure test or bypass and clock through a smaller meter If no movement of the test hand is observed, the gas may be left on. If movement occurs, perform a meter clock test to determine the amount of flow through the meter and follow procedures for locating leakage on customer house piping or appliances. The outlet side of the meter set should always be double checked for minor leakage before concluding that the leak exists on the customer's piping. Consideration should be given to checking the vicinity of the riser at this time for the presence of gas.

LEAK AND ODOR INVESTIGATION
GAS EMERGENCY AND
SERVICE HANDBOOK

EXCEPTION: A meter clock test shall be performed in lieu of a meter spot check in cases of inconclusive leak investigations for commercial or industrial customers where a complete shutdown is impractical at the time. In no case shall practicality take precedence over safety. If an odor persists, or in cases of repeated reports of gas odors, a complete shut down and meter spot check shall be conducted for commercial and
industrial customers. The qualified employee shall coordinate with the business manager or owner prior to any such shut down with consideration given to loss of business, vehicle, or employee traffic, access to equipment, relighting, etc. The qualified employee will notify the Gas Control Room (by calling 509-495-4859 or via radio) and the supervisor prior to performing this task.
Calculating Small Amounts of Meter Flow
Small amounts of flow through gas meters may be calculated using the following formula:
Test Dial Size x # of Increments Traveled x 60 = CFH Total # of Increments Observation Time (min) “Test Dial Size” is the value of cubic feet of flow of the test dial. Express this in a fraction such as 1/2 foot dial = 1/2, 5 foot dial = 5/1, etc. “Number of Increments” refers to the total number of divisions marked on the test dial. “Number of Increments Traveled” is the number of divisions traveled by the test hand during the test. Express this as a fraction or as a whole number, for example 1 (segment) 1/3, 1/4, etc.
“Observation Time” is the period of time required for the spot check (2 minutes, 10 minutes, etc.)
Examples Examples: The test hand on a half foot dial with ten divisions moves 1 division in 2 minutes. 1/2 x 1/10 x 60/2 = 60/40 = 1.5 CFH The test hand on a 5 foot dial with ten divisions moves 2 divisions in 5 minutes. 5/1 x 2 /10 x 60/5 = 600/50 = 12 CFH The standard formula for calculating appliance inputs as shown in GESH Section 10 - Gas Equipment Service shall be used for clocking inputs on gas equipment.
Temporary Repairs/ Cold Weather Exceptions
When a repair cannot be made safely and effectively to stop a gas leak in the customer's house piping and/or equipment, the first responder at their discretion, may leave the gas turned on, provided the gas leak is less than 4 cubic feet per hour and not hazardous. The customer shall be advised to have the equipment or house piping repaired by a qualified dealer, contractor, or service agency. The conditions found, action taken, the amount of gas leakage, why the leak was not considered hazardous, and the advice given to the customer shall be noted on the order.

SERVICE HANDBOOK

Hazardous Conditions A Hazard Notice shall be issued and left on the equipment or piping stating the conditions found and the reason it is hazardous. Hazardous conditions found on customer’s equipment shall be corrected or the appliance shall be shut off by disabling or disconnecting by capping/plugging the line serving the appliance. If it is not possible or practical to disable or disconnect the appliance, the gas meter shall be
closed and locked off at the service valve. The customer’s signature should be obtained, and a copy left with the customer. A duplicate copy shall be retained in the local construction office and a copy forwarded to the inspecting authority as applicable. The customer shall be referred to have a qualified dealer, contractor, or service agency make the necessary safety repairs. Conditions found and actions taken shall be recorded on the gas operating order. These procedures for issuance of a hazard notice shall be followed in each case where such a notice is referred to in this handbook. Reinstatement of Service House piping that has been shut-off pending leak repairs shall be pressure tested by the contractor or customer performing the repairs. Air tests, if required, shall be performed to the satisfaction of the authority having jurisdiction per local code. In cases where Avista Utilities is the authority having jurisdiction, a meter spot check shall be performed by the employee with all house piping branches and appliances connected. After leak repairs have been made and verified, the employee shall unlock the meter and allow the dealer or contractor to relight the gas equipment. The relighting and inspection of the gas equipment may also be performed by Avista gas personnel. SIMPLE CODE 5 IN RESOLUTION
A shutdown of the customer’s house line and equipment is not required during a leak investigation when
all the following occurs:
1. Odor is determined to be from another source and not mercaptan/natural gas (example: sewer
gas, dead animal, overcharged battery)
2. A CGI reading of zero ppm gas in ambient air within the structure

CAN’T GAIN ENTRY (CAN’T GET IN) SITUATIONS
Can’t Gain Entry Procedures
In situations where the customer is not home or access is not readily available to investigate for or confirm the presence of natural gas in a building or structure, the following procedures shall be followed:
• A leak survey shall be performed completely around the structure in question using an approved leak detection instrument. If access for survey around building can’t be attained, pursue forced entry procedures below. Special attention shall be taken around doors, windows, at the basement wall, and at other areas where the presence of natural gas coming from inside the structure may be detected. In order to assure a leak does not exist outside the structure, a bar hole test or ppm survey shall also be performed in the area of the gas meter set assembly.

• A meter spot check shall be taken to assist in determining the absence or presence of gas leakage in the house piping system or on the customer's gas equipment. If a meter spot check shows consumption, a meter clock test shall be performed. A meter clock test showing consumption of less than 4 CFH may represent “normal” pilot flow for residential customers. Commercial/industrial customers and other situations (such as master meter systems) shall be evaluated by the qualified employee.
• Meters showing excessive flow (taking into account appliances cycling on and off) of equal to or greater than 4 CFH shall be closed and locked pending access to the customer's equipment and house piping. A hazard notice shall be filled out with the appropriate information and left on the customer premises that meter was serving. A “Field Request –Miscellaneous-Shut Off Meter” order shall be generated for the meter premises. Completing this order will ensure appropriate customer follow-up communications are completed.
• If no indications of gas are found and the meter registration is normal (less than 4 CFH), the gas may be left on at the qualified employee’s discretion until access is gained to continue the investigation. The appropriate Can't-Gain-Entry notice shall be left on the customer’s premise where the customer is most likely to see it. The notices shall advise the customer to call the
Company to continue the investigation and shall have a 24-hour phone number where they can call to obtain service.
• In situations when the customer cancels the order over the phone or in person follow these procedures: Survey around the entire structure, spot check the meter, and if the spot check shows flows, perform a meter clock test, and document all information from the customer as to why the order was not completed as normal. Forced Entry If gas is found to be entering a building, or suspected to be entering a building, the meter shall be closed, emergency procedures followed, and the qualified employee shall attempt to obtain entry by contacting the occupants and informing them of the situation. If the customer is not home or if access is not readily available, forced entry may be used. If forced entry is used, the police or other emergency services shall be contacted and informed of the situation through the Gas Control Room. The first responder shall wait for the emergency services personnel to arrive and perform the forced entry. Conditions found and actions taken (including specific information on the police and/or fire officials present) shall be recorded on the appropriate gas operating order. The construction manager or supervisor shall also be notified. Consideration should be made to disconnect the electricity at the transformer. Gas Control Room Notification The Gas Control Room shall be notified, by calling 509-465-4859 or via radio, as to the conditions found upon gaining entry and whether a construction crew or other assistance is needed to make permanent repairs. Remaining on the Job The first responder shall remain on the job site until the situation is safe and poses no hazard to the public or until relieved by a supervisor or other trained and qualified gas employee. Temporary Postponement of Repairs Aboveground Grade 2 and Grade 3 leaks in a well-ventilated outside area may be temporarily postponed due to weather or workload consideration. If the postponement of the repair is due to the customer not being home and meter shut off is required, spot check the meter. If the spot check shows flow, clock test the meter for less than 4 cubic feet per hour (CFH) and issue a hazard notice. Follow the MSA

Investigation Procedure outlined in this section for bar hole survey or ppm survey. Attempts shall be made to contact the customer within 48 hours to arrange for access to re-light the equipment. Postponements due to special considerations shall only continue until necessary parts and materials are available, or the weather clears. In no event shall the postponement extend past the repair or monitoring timeline for the specific grade of the leak. The decision to postpone repairs shall be made by a trained,
qualified gas employee. Consideration shall be given to proximity to sources of ignition, customer concerns about the leakage or the odors, possibility of the leak amount increasing, etc.
AVISTA-SIDE LEAK AND ODOR INVESTIGATION Facilities Covered
This section covers aboveground and belowground facilities upstream of and including Avista’s gas meter.
Methods of Detection When investigating an outside leak or odor, the first responder shall employ as many safe methods of detection as necessary to locate the source of leakage or odor. These methods include, but are not
limited to, the use of the sense of smell, soap and water solution, a meter spot check, combustible gas indicator, bar hole, approved leak detection instrument, or other applicable tools. The customer shall be questioned, if available, to help in determining the exact location of the leakage or odors.
Aboveground Leakage Grade 1 leaks on aboveground company facilities shall be corrected immediately, isolated by either closing the appropriate valve or by taking other practical measures. For more information regarding aboveground leak survey classification, see Gas Standards Manual, Specification 5.11, Leak Survey, “Aboveground Outside Leak Classification” and “Aboveground Inside Leak Classification.”

Investigation at Aboveground Avista Facilities Qualified employees responding to reports of gas odors, gas leaks, or suspected gas leakage at aboveground Avista facilities shall first determine if a leak exists on the aboveground Avista facility by using soapy water, a combustible gas indicator, an approved leak detection instrument or other applicable tools. If a leak is found it shall be repaired and documented as appropriate. Once the leak is repaired, or if no leak is found on the aboveground Avista facility, a meter spot check shall be performed if the aboveground Avista facility is a meter set assembly (MSA). If the meter registers flow, perform a meter clock test, if the clock test shows 4 or more cubic feet per hour on the meter, a customer-side leak investigation shall be performed and documented as outlined in this section. If the meter registers less than 4 cubic feet per hour (CFH) on the meter, no customer-side investigation is required. (For Commercial and Industrial Meters, refer to the EXCEPTION for customer-side leak and odor investigations under “Meter Spot Check Procedure”, earlier in this section.) The presence or absence of underground leakage shall be determined in the immediate area around the aboveground Avista facility by performing a type of leak survey for any or all the following conditions:
• After the leak at the aboveground Avista facility has been repaired
• If no leak is found on the aboveground Avista facility
• Every time monitoring a leak on a meter set assembly without a repair

SERVICE HANDBOOK

This shall be accomplished by performing a bar hole survey utilizing a CGI unit in “percent gas mode” or by performing a ppm survey utilizing either an approved leak detection instrument or CGI unit in “ppm mode” that is capable of detecting a concentration of 50 ppm or less. Should any concentration in the “ppm mode” be found, a bar hole survey using a CGI in the “percent gas mode” is required to be used to grade and pinpoint the leak. If a percentage of gas is found during bar holing, an Avista-side leak and odor investigation shall be performed and documented as outlined in this section. If zero reads
are found during the initial survey, no other action is required. For a bar hole survey, the location and results of each bar hole shall be documented. For a ppm survey, describe the area surveyed and record the results found. Listed below are examples of descriptions that can be utilized:
• From meter _____ ft along service
• From meter along foundation ____ ft. in each direction
• From repair back to service tie-in on 3rd party excavation
• Along split service(s)
• From _____________ intersection, ____ ft. in each direction along main
• From _____________ address, _____ ft. in each direction along main
• If none of the above apply, write a brief description of the area surveyed in report/comments area. Survey Limitations: To determine which type of survey to use above, consideration must be given to limitations such as frost, rain, high winds, surface sealed by ice/water, paving, concrete, or other issues that would prevent an effective survey. Underground Leak Determination The presence or absence of underground leakage shall be determined by performing a bar hole survey utilizing a CGI unit in “percent gas mode” or a ppm survey utilizing either an approved leak detection instrument or CGI unit in “ppm mode” that is capable of detecting a concentration of 50 ppm or less. Should any concentration in the “ppm mode” be found, a bar hole survey using a CGI in the “percent gas mode” is required to be used to pinpoint and grade the leak. For a ppm survey, describe the area surveyed (refer to “Investigation at Aboveground Avista Facilities” in this section for examples of descriptions) and document the results found. For a bar hole survey, the location and results of each bar hole shall be documented. Checks shall be made at the following locations to determine the extent of the leakage:
• The point of entry of all underground utilities to a building or structure (gas service riser, water service, sewer, conduits, etc.)
• At cracks in exterior basement walls and around the perimeter of the building foundation.
• Over the service line and out to the main, as necessary.
• At street openings such as curb boxes, drains, vaults, manholes, etc. in the immediate area.
• In the interior atmosphere of the basement of any building or structure involved in the
investigation.
• At any other location where natural gas may accumulate or migrate. Underground Leak Investigation The Avista First Responder / Leak Survey Technician (as applicable) shall investigate for the presence of underground leakage by taking underground samples, using bar hole sampling in the percent gas mode, when any of the following conditions exist:
Staff_PR_007 Attachment A Page 35 of 133

LEAK AND ODOR INVESTIGATION
GAS EMERGENCY AND
SERVICE HANDBOOK

• When leakage on a meter set assembly or outside customer house piping is repaired and gas odors persist.
• When an Avista-side or customer-side odor investigation is intermittent or inconclusive as to the source of the odor.
• When it is determined that we have previously responded to a leak or odor call at the same premise location within the past 30 days.
• When any fire department (or other emergency responder) has requested our response to check our gas facilities (example: close a meter due to fire, continue a leak investigation begun by the fire department, etc.). Refer to GESH Section 17- Incident Investigation.
• In all cases of failures of gas facilities, or when our gas facilities are involved in fires or explosions, refer to GESH Section 17, Incident Investigation.
• In any other situation where it is suspected that natural gas may be leaking or migrating
underground.
• When there is suspected damage beyond a break in a main or the possibility of multiple leaks.
• When a service line has been damaged by third party excavation. (Refer to “Service Line Leak Survey”, later in this section for further details) When gas has been found below ground within one foot of the building’s outside wall, a customer-side leak and odor investigation shall be extended to the inside of the building. Refer to GESH Section 4 - Emergency Procedures. Survey Limitations: To determine which type of survey to use above, consideration must be given to limitations such as frost, rain, high winds, surface sealed by ice, water, paving, concrete, or other issues that would prevent an effective survey.
Pinpointing/Centering Pinpointing is the process of tracing a detected gas leak source. It should follow an orderly systematic process to minimize excavation. When underground leakage is detected, a ppm-only survey is not sufficient. A percent gas-in-air survey must be combined with a bar hole survey. The following procedure for centering or pinpointing the leak shall be followed. A subsurface survey or leak centering procedure shall be conducted by taking samples with a combustible gas indicator in a series of available openings (sewer manholes, electric or telephone substructures, etc.), or bar holes over or adjacent to the pipeline or facility. The location of the gas facility and its proximity to buildings and other structures should be considered when determining the spacing of sample points. Spacing of sample points along the main or service will depend on soil and surface conditions but should never be more than 20 feet apart. Where a pipeline passes under a paved area, samples should be taken at the entrance and exit points of the paved area. In areas of extensive paving, consideration shall be given to drilling permanent test holes. When conducting the survey, all bar holes should penetrate to approximately the same depth. Readings taken at the same depth will enable a meaningful comparison between samples. The reading should be taken at the bottom of the test hole. Care shall be taken not to aspirate water into the instrument and all CGI probes shall be equipped with a device to prevent the drawing in of fluids. Refer to Gas Standards Manual, Specification 5.19, Combustible Gas Indicator Testing and Calibration” on how to measure the concentration of methane in a bar hole or other confined area. When taking each sample reading, the employee performing the survey shall use the most sensitive scale on the instrument. Any indications shall be investigated to determine the source of the gas. Care should be taken when probing, especially around plastic pipe.
Staff_PR_007 Attachment A Page 36 of 133

LEAK AND ODOR INVESTIGATION
GAS EMERGENCY AND
SERVICE HANDBOOK

Sample patterns should include points as close as possible to the main or pipeline, and adjacent to service taps, known branch connections, Dresser fittings, or other compression couplings. Risers and buried piping near building walls should also be sampled. Samples shall continue to be taken until the area limit of the leak is determined, and until the readings have been sufficiently analyzed so that the suspected center or source of the leak is determined.
Locations with the highest readings will normally indicate that they are closest to the center of the leak; however, other factors may preclude this. In instances where readings of 100 percent gas are obtained in several bar holes, it may be necessary to use an approved evacuator to purge each bar hole until the source of the leak is identified. In no case should air ever be injected into a bar hole, as this could result in the gas being driven through the soil into a structure. Remember when analyzing readings that there is a potential for multiple leaks. The locations and percentage of gas in air readings obtained with the combustible gas indicator shall be documented on the appropriate gas operating order. Indicate the approximate locations where the samples were taken and the corresponding gas-in-air percentage readings in relation to the involved structure or other physical landmarks in the area.

Venting Underground Leakage All underground leaks shall be vented to the atmosphere as soon as possible. Underground samples shall be taken at practical time intervals to determine the extent of migration during repairs, and to determine when such concentrations have reached a safe level. If excavations cannot be left open, for example, due to traffic, the excavation should be filled with a granular material such as gravel until the gas is completely vented. Gas Present in Sewer or Duct System If gas is found to be migrating to or accumulating in sewer or other duct systems, the first responder shall make a complete survey of the affected system to determine the area limits of the leakage. All buildings or structures served by the system or adjacent to it shall also be checked for the migration and/or accumulation of natural gas. Emergency procedures shall be followed to protect people and property if gas is found to be migrating in sewer or duct systems. Manhole covers and other lids should also be removed, and the open manhole barricaded to aid in venting. Underground leaks shall be pinpointed and classified per the Leak Classification guidance in this section. Leaks classified Grade 1 shall be repaired immediately. Grade 2 and 3 leaks shall be scheduled for repair per the judgment of trained, qualified field persons on the scene. In all cases, leakage that is found to be migrating to a building foundation, accumulating in an enclosed area or tunnel, or that may pose a hazard to the public or property shall be repaired immediately. Leak Repair and Residual Gas Checks After any underground leak is repaired it shall be checked for residual gas while the excavation is still open by a person qualified in Avista Side Leak Investigation. The perimeter of the leak area shall be bar holed and checked with a combustible gas indicator in percent gas mode to determine if repairs were adequate and if there is any migration from a secondary leak. A minimum of four bar hole readings shall be taken at equally spaced points at the perimeter of the excavation or from within the bell hole prior to backfill to fulfill this requirement. If readings indicate the presence of gas, the perimeter shall be expanded, and additional bar hole readings taken until the extent of the leak is found and documented down to less than 0.05 percent gas in

SERVICE HANDBOOK

air. If the discovery of gas is determined to be a second leak a new order shall be established by contacting the Contact Center. Bar hole locations shall be mapped as appropriate. EXCEPTION: When a leak is found in a valve box and the leak is repaired by performing maintenance on the valve, a reading from a combustible gas indicator shall be taken near the bottom of the valve box after the repair is made. If the reading is zero percent gas in air, bar holes are not required, and the reading shall be documented on the order. If the reading indicates the presence of gas, bar holes shall be taken
around the perimeter of the leak area as described above.
Repairs to damaged service lines require additional leak survey actions. Refer to the Service Line Leak Survey section below. Whenever a pipeline is exposed, whether steel or PE, an Exposed Pipe Inspection Report form, N-2534, shall be completed. Further detail regarding the use of the Exposed Pipe Inspection Report is detailed in Gas Standards Manual, Specification 3.44, Exposed Pipe Evaluation.
Pressure test information is required if a section of pipe is replaced. It can either be tested in the field or
by using pretested pipe. Refer to Gas Standards Manual, Specification 3.18, Pressure Testing. When exposed, underground Dresser-style or other steel mechanical compression fittings shall be cut out or canned (barreled). A Cathodic Protection Technician shall be contacted to verify that the fitting is not
being used as an isolation point. Cutting out or barreling may inadvertently create a problem between two separated cathodic protection systems so additional steps may be necessary before removing or
barreling the fitting.
Reinstating a Damaged Service Line
Refer to Gas Standards Manual, Specification 3.18, Reinstating Service Lines.
Service Line Leak Survey
When a service line has sustained excavation damage (even without apparent leakage) by a third-party excavation, a bar hole survey or a ppm survey shall be performed from the point of the damage to the
service tie-in at the main or after the branch. Should any concentration in the ppm mode be found, a bar hole survey using a CGI in the percent gas mode is required to pinpoint and grade the leak. Broken tracer
wires and nicked coatings do not require the leak survey to occur.
Follow-up Inspections for Residual Gas
In the case of a repaired underground leak where residual gas remains belowground within one foot of a building wall, the employee shall remain on scene to actively monitor and lower the degree of hazard until
the gas concentration within 1 foot of the wall is less than 1 percent gas-in-air and falling as determined by three successive reads, no sooner than 20 minutes apart. (Reference this section and GESH Section
4, Emergency Procedures.) The employee shall find the perimeter of the readings by bar holing until less than 0.05 percent gas-in-air is detected. In cases away from structures, where there is residual gas in the ground after a repair, regardless of the
grade of the leak, a follow-up inspection with a combustible gas indicator in the percent gas mode, shall be made as soon as practical, but in no case later than 30 days following the repair. The repair shall
continue to be rechecked until a reading of less than 0.05 percent gas-in-air is obtained by taking bar hole readings, and the leak repair order is closed. Bar hole readings should be taken as close as possible to the previous reading locations.
Staff_PR_007 Attachment A Page 38 of 133

LEAK AND ODOR INVESTIGATION
GAS EMERGENCY AND
SERVICE HANDBOOK

If any residual gas exists, the employee shall find the perimeter of the readings by bar holing until less than 0.05 percent gas-in-air is detected, to assure a new leak source from outside the original site is not occurring. If a new leak is discovered, this must be treated as a new investigation and must be documented separately on a new leak order. This will allow for proper documentation of the cause of the new leak and for filling out an Exposed Pipe Inspection Report as applicable. Bar hole locations shall be mapped as appropriate.
Large amounts of gas that have saturated the ground may take additional time to completely vent.
Successive readings should indicate a consistent drop in gas-in-air concentrations over time. If a reading of less than 0.05 percent gas-in-air is not obtained after a reasonable time allowance for venting, the leak repair shall be excavated and visually examined for defects, and the adjoining pipeline checked for additional leakage. If a defect in the leak repair is found or if additional leakage is indicated, the leak shall be graded, and
repairs made. BLOWING GAS, ODOR CALLS, AND DAMAGE EVENTS – RECORDING INFORMATION: NOTE: Refer to Gas Standards Manual, Specification 1.1, Glossary, for a definition of Damage. Special information required:

Excavation Damages (Leak or No Leak)
In addition to the above information, when an excavation damage situation occurs, whether the damage results in a leak or just damage to gas facility (i.e., coating, dent, scrape, tracer wire, etc.) additional
information in regard to the excavation and damage shall be captured which includes:
• Root cause of why damage occurred (see definitions below)
• Type of Right-of-Way (ROW)
• Type of underground facility damaged
• Type of excavator
• Type of excavation equipment that caused the damage
• Type of work that was being performed when the damage occurred
• Whether a one-number locator service was notified before excavation commenced, and, if so, the ticket number provided by a one-number locator service; Note: It is critical to acquire the locate ticket confirmation code in the field when available. If not available, a search for the appropriate locate ticket number shall be conducted by the Damage Prevention Administrator or other designated individual by utilizing several sources including but not limited to the One Call Center Ticket Search function (if available) or Avista’s contract locate company’s locate ticket management system.
• Type of locator (contract or company)
• Were locate marks visible in the area

• Was the work area pre-marked (showing the boundary of the excavation site)
• Did this event involve a sewer cross bore?
• Measured depth of top of pipe from grade Damage Without Facilities Locate When facility damage is believed to be the result of an excavation without a facility locate, the Avista First Responder shall acquire the appropriate information to support the lack of a facilities locate and sufficiently document the damage. The initial determination of the lack of a proper facility locate shall be completed by the Avista First Responder. No visible locating marks on the ground and/or the inability of the excavator to produce an appropriately executed locate ticket number is sufficient evidence to conclude a proper facility locate was not completed. A final determination will be made of whether an appropriate facility locate was completed following an investigation and review of the supporting documentation including photographs as prescribed below by the Damage Prevention Administrator and/or the Claims Department.

Photography Requirements The photographs shall be taken of excavation damages and should include sufficient detail to represent information related to the excavation damage. Detail should include but is not limited to:
• Photographs of the damage and the surrounding area from all four directions
• Locate marks or photograph representing lack of locate marks
• Excavation location
• Use of measurement devices such as a tape measure to convey dimensions.
• Use of a note within the photograph to convey the following: o Date of damage event
o Location o Work Order or Service Request number or claim number when available. Photographs shall be emailed to [e-mail]. Regardless of whether or not an excavator will be billed, complete all applicable fields in the Leak Location/Repair Info tab and Excavation Info tab including excavator information for trouble orders in Service Suite (Go-Book field computers) or if computers are down then on the 1st Responder – Gas Operating Order form (Form N-2633).
*For Oregon only:
Take pictures of original site prior to marking newly installed Avista’s facilities to avoid confusion on claims. In areas of ongoing excavation or construction (such as residential or commercial site
development) newly installed facilities shall be located and marked with locate paint or appropriate flagging for backfilled facilities immediately upon placement.
For shaded pipe in a ditch where Avista is not backfilling the ditch, locate and mark using either locate
paint on the sand or “natural gas” caution/warning tape which may be placed on the sand over the pipe using sand in various places to anchor the tape in place so that the location of the pipe is still visible.
(This is a requirement in Oregon per OAR 952-001-0070 (8)). Root Cause Definitions: Select the root cause that most closely matches why the damage occurred. Example: If an excavator
does not have a locate ticket in their name but there are locate marks on the ground and the marks are accurate, not having a locate ticket in their name is a secondary issue, the real cause might be that they Dug Prior to Verifying Marks with hand tools or non-invasive methods. Additionally, the Damage Prevention Administrator or other designated individual shall review excavation damages and locate ticket information to validate the root cause. If there is no locate ticket found for excavation in the area and it has been determined that it was from a previous damage, there should be consideration regarding if the damage was due to a construction defect or damage, or if there were past third-party excavations around the pipeline that may have caused the damage.
• No Locates Requested: No notification made to the One Call Center for a locate ticket.
• Wrong Info to One Call Center: Not enough information or wrong information was provided to the One Call Center.
• Dug Prior to Valid Start Date/Time: Did not wait the two business days before digging.
• Digging with Expired Ticket: Locate ticket has expired.

INCONCLUSIVE LEAK AND ODOR INVESTIGATION
Approved Leak Detection Equipment - (PPM/Bar Hole Survey) Follow Up For any outside gas leak or odor investigation order that proves to be inconclusive, after performing a bar hole or ppm survey it shall be promptly referred to a second leak investigator. The initial investigator
should contact the Gas Control Room to request a second Avista First Responder to assist with the investigation. Alternative leak detection instruments may be required to classify the situation. If a second First Responder is not available, or, the second investigation is also inconclusive, the initial responder shall refer the incident to the Avista Gas Leak Survey Department. Contact the Leak Survey Program administrator and email Gas Programs (#[e-mail]) for follow up and further investigation. Gas employees shall record all information concerning such investigations on the appropriate gas operating (trouble) order. (Exception: area odors where it is impractical to conduct a survey due to the transitory nature of the odor). The employee issuing the follow-up order for the second party investigation shall work with the Leak Survey Department to provide all necessary information regarding the initial investigation.
Detection of Other Combustible Gases Most leak detection equipment will also register a reading for other combustible gases even though they are calibrated for methane. In the case where leak indications are found that originate from a source other than natural gas, the employee performing the investigation shall take prompt action at the time of discovery to protect life and property. The property owner or other adult person on the premises shall be notified that leak indications where found, and that the source is other than natural gas. The customer shall be advised to contact the proper authorities for determination of the exact cause of the indication,
and for correction of the problem. Examples of foreign sources of leak indications include gasoline vapors, sewer or marsh gases, propane vapors, landfill gases, etc.
CLASSIFYING LEAKS: The following procedure establishes criteria by which leakage indications of natural gas may be classified. Each indication of gas leakage must be evaluated by the qualified employee performing the survey. Evaluation includes establishing the area limits or perimeter of the leak, determining if immediate action is necessary to protect life and property, and assignment of a grade to the leak in conformance with this standard.
WAC 480-93-185: In the state of Washington, the above procedures shall be followed, and the company shall take appropriate action regarding its own facilities to protect life and property. In addition, if an indication is found to originate from a foreign source and the situation is ongoing and potentially hazardous, the employee on site shall so inform the property owner or the adult occupying the premises, and where appropriate, shall inform the police department, fire department, or other appropriate governmental agency. If the property owner or an adult person is not available, the company shall, within 24 hours of the leak investigation, send out a letter to the person occupying the premises explaining the results of the investigation. A record of each letter sent must be kept for 5 years.

Grade 1 Leak A leak that represents an existing or probable hazard to persons or property requires immediate repair or continuous action until the conditions are no longer hazardous. The prompt action in some instances may require one or more of the following:
A. Implementation of Company emergency plan.
B. Evacuating premises. C. Blocking off an area. D. Rerouting traffic. E. Eliminating sources of ignition. F. Venting the area. G. Stopping the flow of gas by closing valves or other means.
H. Notifying police and fire departments.
Leaks requiring prompt action: 1. Any leak which, in the judgment of operating personnel at the scene, is regarded as hazardous to life, property, or the environment.
2. Any leak that can be seen, heard, or felt and which is in a location that may endanger the general public or property.
3. Escaping gas that has ignited. 4. Any indication of gas which has migrated into or under a building or tunnel.
5. Any reading outside of a building where the gas could potentially migrate to the inside of a building.
6. Any reading of 80 percent LEL or greater in a confined space. 7. Any reading of 80 percent LEL or greater in small substructures not associated with gas facilities
where the gas could potentially migrate to the outside wall of a building. 8. Any leaks involving construction damage to our pipelines or facilities.
9. Any leaks where police, fire department, other governmental authority, or media has responded, and we have been notified as such.
Note: The Avista First Responder can leave once the investigation is complete, the scene is safe, and a
crew is on location making repairs.
Grade 2A Leak A leak grade assigned only by Avista’s Leak Survey Contractor and defined as: Any leak that is recognized as being non-hazardous at the time of detection, but that justifies scheduled repair based on probable future hazard, and is in a location that would benefit from a response sooner than the standard Grade 2 timeframe. Refer to Gas Standards Specification 5.11, Maintenance Frequencies table for recommended response times. Examples of Grade 2A Leak Situations: 1. Any leak discovered greater than 5 feet from a building foundation but may have the potential to migrate to the building foundation. 2. Any leak discovered in a high use hardscape area such as a street intersection. 3. Any reading between 20 percent LEL and 80 percent LEL in a confined space.

Grade 2 Leak A leak that is recognized as being non-hazardous at the time of detection but justifies scheduled repair based on probable future hazard. Leaks should be repaired or cleared in one year but shall not exceed 15 months from the date reported.
If a Grade 2 leak occurs in a segment of pipeline which is under consideration for replacement, an additional 6 months may be added to the 15 months maximum time for repair noted above. In determining
the repair priority, criteria such as the following should be considered: A. Amount and migration of gas B. Proximity of gas to buildings and subsurface structures C. Extent of pavement D. Soil type and conditions, such as frost cap, moisture, and natural venting
Grade 2 leaks shall be re-evaluated at least once every 6 months until cleared. The frequency of re-
evaluation should be determined by the location and magnitude of the leakage condition. It should be recognized that Grade 2 leaks will vary greatly in degree of potential hazard. Some Grade 2 leaks, when evaluated by the above criteria, will justify scheduled repair within the next business day and
others will justify expedited repair. Others will justify repair within 30 days. These situations shall be brought to the attention of the individual responsible for scheduling leakage repair at the end of the
working day.
Leaks requiring action ahead of ground freezing or other adverse changes in venting conditions:
• Any leak, which under frozen or other adverse soil conditions, could potentially migrate to the outside of a building. Leaks requiring action within 6 months: 1. Any reading of 40 percent LEL or greater under a sidewalk in a wall-to-wall paved area that does not qualify as a Grade 1 leak and where gas could potentially migrate to the outside wall of a building. 2. Any reading of 100 percent LEL or greater under a street in a wall-to-wall paved area that does not qualify as a Grade 1 leak and where the gas could potentially migrate to the outside wall of a building. 3. Any reading less than 80 percent LEL in small substructures not associated with gas facilities where gas could potentially migrate creating a probable future hazard. 4. Any reading between 20 percent LEL and 80 percent LEL in a confined space. (See also Grade 2A Leak earlier in this section. Leak Survey Contractor shall report these as a Grade 2A). 5. Any reading on a pipeline operating at 30 percent SMYS or greater in Class 3 or 4 locations that does not qualify as a Grade 1 leak. 6. Any leak which in the judgment of operating personnel at the scene is of sufficient magnitude to justify scheduled repair. Grade 3 Leak A leak that is nonhazardous at the time of detection and can reasonably be expected to remain nonhazardous. Grade 3 leaks should be re-evaluated during the next scheduled survey, or within 15 months of the reporting date, whichever occurs first, until the leak is regraded or no longer results in a reading.

SERVICE HANDBOOK

Leaks requiring re-evaluation at periodic intervals: 1. Any reading of less than 80 percent LEL in small gas associated substructures such as small meter boxes or gas valve boxes. 2. Any reading under a street in areas without wall-to-wall paving where it is unlikely the gas could
migrate to the outside wall of a building. 3. Any reading of less than 20 percent LEL in a confined space.
Each instrument used for leak detection and evaluation shall be operated and maintained in accordance with the manufacturer's instructions. All instruments shall be calibrated at least monthly or in accordance with manufacturer's instructions, whichever is more frequent. Calibrations shall be performed on a regular schedule using certified test gases.
Re-Classification of Leaks Leaks shall be re-inspected using the same criteria and guidelines used to classify leaks when they are first detected. A Grade 1 or 2 leak can only be downgraded once without a physical repair. After a leak has been downgraded once, the maximum repair time for that leak is 21 months from the date of the downgrade. (The downgrading of a Grade 1 leak classification to a Grade 2 or Grade 3 classification should only occur when the leak has been misclassified.) Maximum effort should be implemented to fix Grade 1 leaks when discovered. A temporary repair, however, may be authorized in cases where an immediate repair is not feasible. A Grade 1 leak that has had temporary repair action taken so that it is no longer hazardous may be left to fix when conditions allow if after three consecutive reads, 20 minutes apart, the reads demonstrate that the gas in air levels are not rising to hazardous levels. A Grade 1 leak that has had temporary repair and is no longer hazardous, should not be left longer that 1 week in this state without the approval of the local construction manager and the Manager of Gas Engineering. Combustible Gas Indicator readings in percent gas mode via bar hole shall be taken DAILY until the final repair is completed. LEAK FAILURE CAUSE DEFINITIONS
The following are definitions and examples for leak failure causes:

SECTION 3 CARBON MONOXIDE (CO) ORDERS
GENERAL Gas service persons responding to and investigating potential carbon monoxide incidents shall take immediate, appropriate action to provide for the safety of the public. Proper safety equipment should be used when it is necessary to enter a structure or building that contains carbon monoxide.
CO Orders When a customer expresses a concern that carbon monoxide may be present, a gas service person shall be dispatched immediately. Can’t Gain Entry
If the customer is not at home or does not answer the door, the service person shall make a reasonable effort to contact the customer by phone. If the customer cannot be contacted, the service person shall lock off the service valve and shall leave the appropriate shut off notice and document the order as applicable. Consideration should be given to call Emergency Services (911) if the conditions warrant. SYMPTOMS OF CARBON MONOXIDE POISONING
Initial symptoms of carbon monoxide poisoning may resemble the flu and a person may exhibit one or more of the following: headache vomiting increased perspiration dizziness nausea weakness (in legs) ringing in ears heart palpitations mental confusion shortness of breath
Moderate carbon monoxide poisoning symptoms can be similar to those of a person who is intoxicated. In cases of severe carbon monoxide poisoning, the skin may turn pink in color and the mucous membranes may turn a cherry red. Concentration (CO in Air) Inhalation Time & Symptoms 35 ppm OSHA time weighted average limit for continuous exposure in any 8 hour period.
200 ppm OSHA Short Term Exposure Limit (15 min.). Slight headache, tiredness, dizziness, or nausea after 2 to 3 hours.

PROCEDURES FOR COMPLETING CARBON MONOXIDE ORDERS
Detecting Instruments When investigating the possible presence of carbon monoxide, the gas service person shall employ an electronic carbon monoxide detection instrument that indicates readings of carbon monoxide in air in
parts-per-million (ppm) increments.
Initial Determination The source of any carbon monoxide emissions shall be determined, evaluated, and the necessary steps taken to ensure the safety of the customer. This includes, but is not limited to, evacuating any persons that may be affected by carbon monoxide concentrations in a structure or confined area, ventilating the premises, closing the appliance shutoff valve, and disconnecting or closing the meter valve and locking it
off, and issuing a hazard notice, etc. Customers that are found to be exhibiting symptoms related to carbon monoxide poisoning shall be immediately moved to an area that has fresh air and medical
attention shall be requested by calling 911. Carbon monoxide orders with the exception of simple resolutions for a CO real or perceived detector malfunction must be finished by conducting the Customer-Side Leak and Odor Investigation as outlined in
GESH, Section 2 – Leak and Odor Investigation. Examples of “simple resolutions” that would not necessarily require the above-mentioned Leak and Odor Investigation could include battery problems
with a CO detector, a defective CO detector or a smoke detector “chirping” that was misinterpreted as a CO detector problem. Document the reason why a Customer-Side Leak and Odor Investigation was not
conducted on the Gas Operating Order.
Documentation
Conditions found, carbon monoxide readings detected, and actions taken shall be recorded on the appropriate Gas Operating Order. The outside ambient air reading shall also be recorded.
CARBON MONOXIDE TESTING: AMBIENT AIR TESTING The following steps shall be taken when responding to requests to check for the possible existence of carbon monoxide in dwellings, buildings, or other structures: 1. Verify the instrument has been calibrated. Turn-on and zero the carbon monoxide detecting instrument in fresh air. If a zero reading is obtained, proceed with the investigation. If a reading other than zero is obtained, check for outside sources of carbon monoxide (vehicles, lawnmowers, etc.) change your location and repeat the zero procedure. If a zero reading cannot be obtained, do not use the instrument until it is checked or re-calibrated. 2. Take samples at the center and at each corner of every room, if practical. The initial readings shall be taken at a level between 3 feet to 6 feet above the floor, with an occasional read being taken close to the ceiling for reference. Enough area should be sampled to give a reasonable representation of the general levels of carbon monoxide throughout the structure. The mechanical room (or other areas where gas appliances are installed) shall also be sampled as
this may give an indication of the source of the carbon monoxide emissions. 3. If unvented decorative appliances or unvented room heaters (where allowed by local code) are present, do not sample directly above the unit to determine a ppm action level per this policy. Samples taken directly at the unvented appliance may or may not have a bearing on whether the appliance is shut off, adjusted, or left as found. The effect on total indoor air quality takes precedence over direct readings as ANSI standards allow for levels above 10 ppm on an air-free sample basis.
Staff_PR_007 Attachment A Page 50 of 133
CO INVESTIGATION
GAS EMERGENCY AND
SERVICE HANDBOOK

4. Calculate an approximate average of the total concentrations of carbon monoxide in the occupied areas of the structure. Use this figure to determine your next course of action. 5. Take any action necessary to safeguard life and property. Evacuate and ventilate, make appliance adjustments, or turn-off equipment to correct the condition and eliminate the concentrations of carbon monoxide. If necessary, issue a hazard notice.
10 PPM Rule
Averaged concentrations of carbon monoxide in the interior ambient air of a structure or building shall not exceed 10 ppm. The 10 ppm limit allows for an ambiance above zero that may be due to sources other than gas appliances; (i.e., close proximity to an industrial area, freeway, or residue from internal combustion engines in the area). This level will not cause immediate harm and may be dissipated by adequate ventilation or removal of the source. The 10-ppm rule assumes that any gas equipment that is designed to be vented to the outside is installed properly and is not spilling exhaust into the building.
In cases where unvented decorative gas appliances or room heaters are in use, it is expected that the emissions directly above the flame area will be higher than 10 ppm due to inherent design features. If an unvented appliance produces over 10 ppm average concentrations in a building during normal operation, the appliance shall be disconnected, the appropriate hazard notice shall be issued (and the appliance tagged), and the customer shall be referred back to the installer to attempt to correct the condition. It is understood that the concentrations in any given room will vary with the amount of ventilation, as well as with the cubic volume of the room itself. One factor to consider will be the reaction of an informed customer that has been advised that the unvented appliance will constantly emit a small amount of carbon monoxide into the living area while it is in use. Customers that are not satisfied with these conditions shall be referred back to the installer of the appliance for resolution.
35 PPM Rule Evacuation of persons in the building shall be performed if consistent average levels of carbon monoxide are present in concentrations over 35 ppm. The service person shall use good judgment in determining the necessity of evacuation; an example would be a concentration of carbon monoxide in an isolated area inside a building that can be safely ventilated without having to evacuate all persons from the building. OSHA has determined that 35 ppm is a threshold limit value of carbon monoxide based on a time-weighted average concentration for an 8-hour workday. Even though this has been established as an industrial work standard for allowable exposure, it is not an indoor residential standard. It is, however, a level that allows for relatively safe entry into a building without self-contained breathing apparatus to determine the source of the carbon monoxide emissions, and it also serves as a standard to allow for safe evacuation of persons before concentrations become life threatening.
200 PPM Rule OSHA has established 200 ppm as the threshold limit value for a short-term exposure to carbon monoxide. This represents the maximum concentration of carbon monoxide to which a worker may be exposed for a period not exceeding 15 minutes. The 15-minute exposure may be repeated up to a maximum of 4 times during an 8-hour shift with a minimum period of 1 hour in fresh air between each
subsequent exposure.
If concentrations are found in a building to be 200 ppm or over, the gas service person shall leave the building immediately and only attempt to notify occupants to evacuate while exiting the building. The control room shall be notified (by calling 509-495-4859 or via radio) immediately and 911 called to assist with evacuation (if persons are still in the building). If possible, the gas meter valve shall be shut off outside or at the curb valve.
Staff_PR_007 Attachment A Page 51 of 133
CO INVESTIGATION
GAS EMERGENCY AND
SERVICE HANDBOOK

Re-entry into the building should not be attempted until the building has been ventilated and the carbon monoxide levels are 10 ppm or lower. The source of the carbon monoxide shall be determined, and corrective action taken per this policy. Customers that are exhibiting symptoms of carbon monoxide poisoning shall be advised to evacuate to an area that has fresh air. Assistance shall be provided in evacuation and 911 shall be called if this is
deemed prudent by the service person, or if the customer is visibly ill. CARBON MONOXIDE TESTING: GAS EQUIPMENT TESTING The following procedures shall be followed when testing for the presence of carbon monoxide in the flue gases of natural gas fired equipment: 1. Verify the instrument has been calibrated. Turn-on and zero the carbon monoxide detecting instrument in fresh air. If a zero reading is obtained, proceed with the investigation. If a reading other than zero is obtained, check for outside sources of carbon monoxide (vehicles, lawnmowers, etc.) change your location and repeat the zero procedure. If a zero reading cannot be obtained, do not use the instrument until it is checked or re-calibrated.
2. Do not make any adjustments to gas appliances prior to the sampling process. 3. Gas appliances that are being checked for the presence of carbon monoxide shall be allowed a
minimum of 5 minutes operational time to allow for warm-up of the flue and combustion chamber. Warm-up time will vary with equipment type and ambient temperatures. 4. If the source of the carbon monoxide emissions is unknown, all gas appliances shall be turned on and allowed to warm-up during the same test period. Special attention shall be given to those appliances that share a common vent system or that are in a common mechanical room. 5. The test should be made under actual operating conditions, if possible, i.e., the door to the mechanical room should be closed if that is the normal position, flame roll-out shields should be in place, and any exhaust fans that may normally be in operation should be turned on. 6. Flue gas samples should be taken immediately after exhaust gases leave the appliance, i.e., as near the base of the stack as possible so that the flue gases are not diluted. If there are multiple openings from the heat exchanger into the draft hood, the service person should take samples out of each opening. This will help to isolate problems with individual heat exchanger cells or burners. Cells should be checked, and the highest reading used (after any final adjustments are made). 7. Conversion burners may require the service person to punch or drill a hole in the vent connector upstream of the draft hood. 8. High efficiency furnaces with plastic vent pipe should be tested at the vent termination. If the vent termination is not accessible, a hole may be drilled for sampling purposes. The service person shall check with the customer prior to drilling any holes in vent piping. Test holes in plastic vent pipe should be sealed with silicone sealer after the sampling is completed. The service person may make adjustments (within the scope of this policy) to attempt to eliminate or reduce the carbon monoxide present in the flue gases on gas equipment. It is understood that it may not be possible to obtain a zero reading on some equipment.

GAS EMERGENCY AND
SERVICE HANDBOOK

100 PPM Rule Vented residential furnaces, water heaters, and boilers shall not produce a level exceeding 100-ppm carbon monoxide in the flue gases after warm up. This level (100 ppm or less) shall be considered acceptable providing that any required cleaning and adjustments have been completed and:
• The appliance is properly vented, and the exhaust gases are not spilling into the building
• The gas input through the appliance has been verified by a meter clock test to be correct
• The main burner and pilot flame have acceptable characteristics, are not sooting or impinging, and have no apparent defects
Residential gas appliances that are producing more than 100 ppm in the flue gases shall be disconnected
and the appropriate hazard notice shall be issued for repairs to be completed by a licensed dealer or contractor.
Residential gas ranges and ovens should be evaluated on the basis of what levels of carbon monoxide
are present in the building after a normal period of operation. Very high levels of carbon monoxide may be present at the oven flue opening, especially during warm-up; however, the products of combustion are
normally greatly diluted in the ambient air of the building. After any required adjustments are made, customers that still have a concern with the carbon monoxide levels being emitted by their gas range
equipment shall be referred back to the dealer or installer for resolution. If the average levels in the ambient air exceed the acceptable levels in this policy (after a normal operational cycle), the equipment
shall be disconnected and capped, and the appropriate hazard notice shall be issued.
Commercial and industrial gas equipment may have higher levels of carbon monoxide that are allowable in the flue gases as specified by ANSI testing standards or other specifications. The qualified employee
shall use good judgment in analyzing the conditions found and referring to the manufacturer's instructions (or other data) in determining a course of action. In any event, customer safety shall take precedence in
situations where the presence of carbon monoxide is a concern.
If a carbon monoxide safety related problem cannot be corrected by the qualified employee, the customer shall be referred to a qualified dealer or contractor, the equipment shall be disconnected and capped, and the appropriate hazard notice shall be issued.
CARBON MONOXIDE DETECTOR ALARMS
Carbon monoxide detectors are devices that are designed to detect the presence of carbon monoxide in residential buildings. They may be of a biomimetic or semiconductor design.
Type of Detectors The biomimetic detector is normally battery operated and uses a synthetic hemoglobin that absorbs carbon monoxide. The sensor and the battery are usually combined in a slide-out unit that must be replaced every several years. The sensor will darken as carbon monoxide is absorbed and trigger an alarm. The sensor must be placed in fresh air in order to clear it. These detectors may be especially susceptible to any foreign matter that may collect on the sensor such as dust or hair spray. The semiconductor detector normally operates on household current and uses a sensor, usually coated with a metal oxide, to detect carbon monoxide. Carbon monoxide molecules collect on the sensor that triggers a reading. These sensors will also burn off carbon monoxide and other contaminants every few minutes in order to display an accurate current reading or trigger an alarm. These detectors are less susceptible to false alarms due to other contaminants.

UL 2034 Carbon monoxide detectors are currently being manufactured to Underwriters Laboratories (UL) UL 2034 standards, as revised October 1, 1998. An outline of some of the applicable points of the standard is as follows:
An 85-decibel alarm shall sound within:
189 minutes at 70 ppm 50 minutes at 150 ppm 15 minutes at 400 ppm (Previous requirements stated the alarm must sound within 90 minutes if 100 ppm is present, within 35 minutes if 200 ppm is present, and within 15 minutes if 400 ppm is present).
The alarms will now ignore low levels of carbon monoxide (30 ppm) for at least 30 days without alarming.
CO Alarm Procedures
A qualified employee shall respond and investigate when notified that a residential carbon monoxide
detector alarm has gone off at a location that is served by Avista Utilities gas facilities.
The qualified employee shall follow the procedures as outlined in this Section in investigating the possible presence of carbon monoxide. The alarm should be silenced prior to conducting the investigation.
Readings found on detectors with digital displays shall be recorded on the appropriate Gas Operating Order. Attention should be paid to any conditions that may be affecting the operation of the detector such
as proximity to appliances, the type or style of detector, ambient dusty conditions, cigarette smoke, inversion layers, etc.
In cases where the customer detector has indicated the presence of carbon monoxide, yet the qualified
employee’s detecting instrument fails to indicate a reading, the customer shall be notified of the situation. A recommendation shall be made that the customer should contact either the store where the detector
was purchased, or the detector manufacturer for further instructions. In addition, the customer shall be advised to carefully read the detector instructions to make sure that the detector has been installed and
operated according to the manufacturer's instructions.
Carbon monoxide detectors that have been sold by the former WWP Gas Companies shall be inspected and replaced per the warranty terms that existed at the time of purchase. Battery replacement is not
covered by any warranty. NOTIFICATIONS The Control Room shall contact Claims and either the appropriate operations manager or on call supervisor when any of the following situations occur:
• Evacuation has occurred by the emergency first responder or Avista due to carbon monoxide levels
• Hospitalization and/or medical treatment related to carbon monoxide has occurred or is believed to have occurred

SECTION 4 EMERGENCY PROCEDURES – BLOWING OR UNCONTROLLED ESCAPING NATURAL GAS
GENERAL In instances where the procedures outlined in this section or other portions of the Gas Emergency and Service Handbook do not reasonably meet the demand of the task being performed, the Serviceman or Avista First Responder is empowered to use good discretion and judgment to perform the duty outside of normal procedures. Procedure changes or deviations made in the field shall be documented on the work order explaining the need for the change and what alternative procedure was completed. Situations involving blowing or uncontrolled escaping natural gas, high concentrations of gas in buildings
or structures, or accumulations of gas where it may pose a hazard to the public or property, the Avista First Responder shall first evaluate the emergency scene, and then take immediate action to safeguard life first then property. Employees shall reference Gas Standards Manual, Specification 3.17, Purging Pipelines for further information and things to consider regarding Prevention of Accidental Ignition.
Employees responding to natural gas emergencies shall be trained and qualified under current Company
standards, and per any applicable State or Federal regulations. Such employees shall adhere to the following procedures in controlling emergency situations:
• Respond immediately to any gas related emergency call. This includes blowing gas, gas detected inside or near a building, failures of company facilities, odors or leaks reported by the fire department or other first responders, fires involving natural gas facilities, explosions, natural disasters that have potential to damage natural gas facilities, etc.
• Evaluate any emergency scene to assess the extent of any leakage or damage, and to determine what action is necessary to safeguard life first and then property (such as other utilities that can cause an immediate hazard). Evaluation actions shall include the use of a combustible gas indicator that is capable of indicating percentage gas in air readings. 1. If emergency services are on site, coordinate with any emergency personnel and/or the Incident Command Center at the emergency scene. Incident Commander shall be advised of our arrival, and of what action we intend (or need) to take in relation to our gas facilities. Key emergency personnel also should be warned of any potential dangers and shall be kept updated as to the progress of our activities. 2. If you are the first emergency responder on site, you should establish the Incident Command Center and shall be the Incident Commander until other emergency services arrive or you relinquish command to someone else. Notify emergency services immediately if assistance is required for evacuation, fire control, traffic control, medical assistance, etc. The request should be made through the control room (by calling 509-495-4859 or via radio) which may also include any additional employees and equipment, as needed.
Notify emergency services in the following rupture situations:
• Any unintentional and/or uncontrolled release of gas from a high pressure source

• Notify and evacuate all persons that may be affected by the emergency situation. Persons in buildings or structures that may be subject to accumulations of uncontrolled natural gas shall be notified and evacuated immediately. Persons subject to a potentially hazardous situation outside shall be evacuated immediately to a safe distance. Bystanders should be notified to stay clear, and the hazardous area shall be barricaded off using warning tape and/or warning signs.
• Potential sources of ignition shall be removed or eliminated from the emergency area, if possible.
• Uncontrolled, escaping natural gas shall be shut off by valve, or controlled using other approved methods, as the situation dictates. Fires fed by natural gas should not be extinguished until the
gas flow is stopped unless necessary to protect lives or property.
• The affected area shall be monitored both above and below ground for additional leakage and migration of natural gas. Buildings and structures involved in the gas emergency shall be checked with a combustible gas indicator at continual intervals depending on the situation and if safe to do so. The area limits (extent of migration) of any leak shall be determined and communicated to the Incident Commander, as well as to any affected members of the public. Monitoring of the leakage shall continue until the leakage is repaired and the concentrations are found to be zero percent gas in air in the general atmosphere inside the building or structure.
• Accumulated natural gas shall be ventilated to the atmosphere by safe means.
• When gas is below ground at the outside wall of a building, a qualified gas employee shall remain on the scene to actively monitor and lower the degree of hazard on a leak. The employee shall document the concentration levels and the times the measurements are taken and not leave until the gas concentrations below ground are less than 1 percent within 1 foot of the building’s outside wall and trending downward as measured by three successive reads no sooner than 20 minutes apart. Any variation to this standard must be done in concurrence with Gas Engineering and the reason(s) for the variance shall be documented.
• Company gas pipelines and facilities shall be repaired in a timely manner and shall be left in a safe, operable condition by qualified gas service personnel or crews.
• Customer facilities shall be restored when safe to do so. Restoration procedures shall take into consideration customers that have special needs such as hospitals, rest homes, handicapped persons, etc. Customer equipment shall be left in a safe condition or left off and tagged if found to be hazardous. (Refer to Section 5 - Emergency Shutdown/ Restoration of Service.)
• Conditions found and actions taken shall be documented on the 1st Responder Gas Operating Order (form N-2633). Gas in air readings obtained while pinpointing or centering underground
leaks, as well as leak indications inside structures, shall be recorded on the appropriate gas form, N-2633.

Temporary Control of Escaping Gas
HP Control Only qualified gas employees shall attempt to control blowing gas that has a pressure above 60 psig. High pressure damaged facilities shall be immediately reported to the control room (by calling 509-495-
4859 or via radio) and to supervision. The employee shall not attempt to enter the immediate area except to protect lives. Control of high pressure damaged facilities shall only be by use of distribution or transmission line valves, or by the appropriate high pressure stopping devices employed at a location that is a safe distance from the damage. As an option, the pressure may be lowered in order to enable “standard methods of control”, if supply
conditions permit.
Standard Methods of Control (60 psig or less) Closure of available valves is the preferred method of control. In absence of a practical way to valve off a damaged pipeline or facility, the following means may be employed to temporarily control escaping natural gas in an emergency situation: Broken Steel Pipe (60 psig or less)
• Leak repair clamps (Adams style clamps) are stocked in all construction offices. Follow the procedures outlined in Gas Standards Manual, Specification 3.35, Detailed Procedures for use of “Adams” Style Repair Clamps, for installation on damaged pipe.
• A tapered wooden plug may be driven into a circular pipe end using a brass hammer to avoid sparking. Caution should be exercised as the plug may crack, split, or dislodge. Secure the plug with tape or wire until other means of control are available.
• Expander plugs or valve changing devices may be used to stop the flow of gas in a pipe that has retained most of its circular shape.
• Hydraulic or manual squeeze off tools are available in varying pipe sizes in the construction areas. Follow the manufacturer's instructions for use of these tools. Shutoff will typically be less than 100 percent, so an additional means of completing the shutoff may be necessary. Broken Plastic Pipe Plastic pipe squeeze-off tools are available for all sizes of plastic pipe in our system. Manufacturer's instructions, as well as the procedure for Squeeze-Off PE Pipe & Prevention of Static Electricity (Gas Standards Manual, Specification 3.34) shall be followed when attempting to squeeze-off plastic pipe. Gas pipelines that have been damaged but temporarily controlled shall not be left unattended. A properly trained gas employee shall continue on the scene until the leak has been permanently controlled or repaired. A temporary repair clamp such as an Adams-type clamp may be left unattended until a permanent repair can be made (as soon as practical). A permanent repair would include a fusion, weld, or the installation of a mechanical fitting. If a valve is closed to secure the gas, this may be left unattended until repairs are made. Stoppers and squeeze-off tools are not considered permanent repairs. If a valve is used to stop the flow of gas, the Avista First Responder shall determine that the gas flow has completely stopped, or other repair methods shall be utilized. Steel services may be temporarily threaded and capped should the Avista First Responder need to leave the scene and the crew is temporarily unavailable.

If it is found necessary to enter a trench or excavation that contains a hazardous accumulation of natural gas, the requirements for respiratory protection shall be followed as outlined in Avista’s Incident Prevention Manual. Underground Electric Precautions
Dig-in damage that occurs in proximity to a buried electric line shall be reported to the appropriate utility for immediate control of the electric line. The Avista First Responder shall not enter any excavation or attempt any control of blowing or uncontrolled gas if an energized electrical line is in the joint trench where the damaged line is located. The individual shall also maintain awareness of any damaged or dangling overhead conductors, as well as for the possibility of "step-potential" when approaching any excavation. Media Inquiries Employees that are approached by reporters or other media personnel shall defer questions to the Avista Utilities Corporate Communications Department. A Corporate Communications Coordinator shall provide answers to questions regarding accidents, incidents, or other Company operations.
• Reporters shall be advised to call Avista’s 24 hour Media Line at 509-495-4174. After normal business hours a representative will be paged immediately. The control room should also be notified (by calling 509-495-4859 or via radio) and can also contact the Media Line in conjunction with other required reporting.
• Field personnel shall always be respectful and courteous when dealing with reporters. Employees shall be careful not to joke or make off-handed remarks regarding the situation, especially when media personnel are present.
• A helpful response to a media inquiry may be stated in this manner: "I'm sorry, but I am not available to speak with you regarding this situation. Our Corporate Communications Department has the responsibility for answering your questions and they will arrange to get you the
information you need. Here is their number." You may also explain that your first priority is to control the situation and provide for public safety.
• If a supervisor is on the scene, the supervisor will coordinate with the media regarding inquiries.
EVACUATION PROCEDURES
In the event that an evacuation of persons from buildings or areas affected by a natural gas emergency is
necessary, emergency services (911) assistance should be requested. If immediate evacuation is required, the following guidelines should be followed:

• Occupants of affected buildings or structures should be advised of the danger (to the extent practical) and should be requested to immediately leave the building.
• Persons being evacuated should be advised to refrain from: operating light switches, operating any electric or electronic devices, using the telephone, cell phones, starting vehicles in the immediate vicinity, operating garage door openers, using elevators, using intercoms, no smoking (lighting of matches or lighters), or doing anything that could result in a source of ignition.

EMERGENCY SHUTDOWN & RESTORATION OF SERVICE
GAS EMERGENCY AND
SERVICE HANDBOOK

SECTION 5 EMERGENCY SHUTDOWN AND RESTORATION OF SERVICE
GENERAL The Company recognizes the need for safe operating procedures if gas pipelines or facilities are damaged, severed, de-pressurized, or otherwise altered to affect the safe delivery of gas to customers at the required utilization pressure. Gas service persons and other gas qualified workers shall adhere to the following procedures (to the extent possible) when engaged in pressure control work, planned and emergency shutdowns, and while restoring service to customers that have been shut off due to such procedures, or due to abnormal weather conditions. The Emergency Planning Worksheet, at the end of this Section, should be used as a guideline to help assist in utilizing the following procedures. SHUTDOWN OF SERVICE
EOP Zone Shut Down In the event that gas service is interrupted to any customers as a result of construction damage, natural disaster, equipment failures, severe system pressure loss, etc. the maps shall be referenced in order to determine if an EOP Zone closure is necessary to shut down the affected system and/or to enable repairs. If an entire EOP Zone must be shut down, the appropriate EOP Zone valve(s) shall be closed. If it is not necessary to shut down an entire EOP Zone, only the appropriate maintained system valves shall be closed or in the case of a plastic system, a smaller area may be shut down by squeezing the pipe or a combination of emergency valves and squeezing. When life, property, or the environment are threatened by the emergency, the decision regarding which type of emergency shutdown to use shall be based on the quickest method of shutting down the system that does not endanger others based on WAC 480-93-100 (5). Closing Meters
Affected customer meters shall be closed at the service valve in cases of confirmed outages, if a system
valve has been closed, or if an EOP Zone has been isolated. The meters shall be left in the closed position until such time as the repairs have been completed and the lines have been pressurized and purged of air.
Marking of Closed Meters Meters that are closed or found closed shall be marked with a marking pen with a single slash mark as shown - “ / “. Maps and Lists
The control room shall have an affected customer list printed and provide maps showing all gas accounts and facilities in the affected area. The list or maps shall be provided to the gas service person or supervisor in charge of the job.
Staff_PR_007 Attachment A Page 61 of 133
EMERGENCY SHUTDOWN & RESTORATION OF SERVICE
GAS EMERGENCY AND
SERVICE HANDBOOK

A determined effort shall be made to identify, reach, and close the gas meters within the affected area. Meters that are found locked off prior to the emergency shutdown shall be noted on the relight list, as well as on the map to avoid restoration of previously closed accounts. RESTORATION OF SERVICE
Pressurization When appropriate repairs have been completed, the crew foreman or supervisor in charge shall confirm the meters have been closed before re-pressurizing the gas pipelines. Upon confirmation, gas personnel shall then re-pressurize the gas mains and services affected. Consideration shall be given, in the case of extensive outages, to re-pressurizing and restoring service according to EOP Zones. Re-pressurization shall be performed safely and at a controlled rate to avoid overpressure of the downstream system. Pressure gauges shall be in place during re-pressurization and shall be monitored until the pressure rises
to the required level and stabilizes.
Purging As necessary, any affected gas pipelines and facilities shall be safely purged of any air or foreign materials prior to restoring service. The procedures as outlined in the Gas Standards Manual,
Specification 3.17, Purging of Pipelines shall be followed.
Restoring Service Upon successful re-pressurization, gas service persons or other trained and qualified gas personnel shall proceed to restore service to each individual customer that was affected by the shutdown. Each meter
that is restored to service shall be meter spot checked and the gas equipment inspected per Company service policy. A relight list or similar documentation shall be issued for each account, turned into the
supervisor in charge upon completion, and will serve as the official documentation of the completed restoration.
Note: An order should be requested if abnormal conditions are found. A flow and lockup pressure test is not required to be completed during restoration of service after an
emergency shutdown. It may, however, be done at the discretion of the Operations Manager or the Gas Incident Commander.
If a customer refuses Avista access inside their home or business to perform a safety check of the equipment, the Gas Serviceman shall strongly advise the customer to have a qualified dealer, contractor, or service agency perform the relight. The meter shall be left off at the A-9 (downstream) valve. It there is not an A-9 valve present, one needs to be installed and turned off. In the event an A-9 valve cannot be installed at this time, the meter shall be shut off and locked off at service valve. Document the need to return to install an A-9 valve in the Gas Operating Order as applicable to ensure follow-up will occur. DO NOT spot check the meter and leave it on. Marking of Meters Turned on by Company
Meters that have been turned back on by company representatives, shall be marked with a counter slash through the existing slash to create an “ X ”.
Staff_PR_007 Attachment A Page 62 of 133
EMERGENCY SHUTDOWN & RESTORATION OF SERVICE
GAS EMERGENCY AND
SERVICE HANDBOOK

Meters Turned On by Other than Avista In cases where it is determined that the meter has been turned on by other than a company employee or their representative, an attempt shall be made to gain access to inspect the equipment for safe operation. If access is gained, mark the meter appropriately and complete the documentation.
If access is refused or the Avista responder cannot gain entry, the meter shall be spot checked. If there is flow, perform a meter clock test. If the clock test shows flow greater than or equal to 4 CFH and it cannot be confirmed from outside the premises that the usage is reasonable, the meter shall be shut off and locked at the service valve due to unaccountable gas flow. Issue a hazard notice with the reason being “Unaccountable Gas Flow”. A “Field Request-Miscellaneous-Shut off Meter” order shall be generated for the meter premises. Completing this order will ensure appropriate customer follow-up communications are completed. Additionally, document the access refusal or can’t gain entry situation on the gas operating order.
If the flow is less than 4 CFH, the meter may be left on at the Gas Serviceman’s discretion. Document the actual amount of gas flowing through the meter and advise the customer of this situation.
Dealer Notification
Consideration shall be given to notifying local dealers of a major outage. This may help to prevent customers from incurring charges from heating dealers for restoration of service. The media may also be
used to help notify customers of the existence of an outage in their area, so that dealers are not called unnecessarily. Can’t Gain Entry Situations
In cases where the restoration of service cannot be completed due to the customer not being home, the
service valve shall be left off and locked. The appropriate Can't Gain Entry notice shall be left on the premises, and the gas operating order or relight list shall be noted accordingly.
Cold Weather
In cold weather, consideration shall be given to making additional attempts to gain access to restore
service (i.e., contacting by phone, checking with neighbors, etc.) LOW PRESSURE SITUATIONS
Monitoring Pressures Trained and qualified gas personnel performing work on district regulator stations or other pipelines and facilities shall install accurate pressure gauges upstream and downstream of the work site. System pressures shall be continuously monitored if the work being performed could result in loss of pressure or overpressure to the system. Pressure Drops
In the event that it is possible that the pressure in mains or services has dropped below the minimum safe utilization pressure, causing potential pilot outage or equipment malfunction, the incident commander, crew foreman, or supervisor on the scene shall make a decision as to whether to shut down the affected area. This decision shall be made as quickly as possible, given the individual circumstances. (When
Staff_PR_007 Attachment A Page 63 of 133
EMERGENCY SHUTDOWN & RESTORATION OF SERVICE
GAS EMERGENCY AND
SERVICE HANDBOOK

determining if the system pressure has potentially dropped below the minimum safe utilization pressure, personnel should consider size of main, system operating pressure, size of effective area, temperature, time of day, and if there are any “Low Gas Pressure” or “No Heat” orders.)
Plan of Action
In order to assess whether the system should be shut down, the gas employees on the scene shall perform pressure checks at random points, and at the outer limits of the system involved as soon as
practical. The possibility of pilot outages should be verified quickly by checking customer equipment. Actual pilot outages shall be recorded and mapped. All factors shall then be analyzed, and a plan of action formulated. If doubt exists as to the extent of the outages, a shutdown of the system is normally the safest alternative. Supervisory personnel should be advised of shut down decisions as appropriate. Public safety must not
be compromised in favor of the inconvenience of losing customers. If it is found necessary to shut down a system, the procedures for shutdown and restoration of service as outlined in this section shall be
followed.

 Have the systems maps been obtained and analyzed for the most effective shutdown pattern?
 Is a complete shutdown of all meters in affected area necessary? (This is normally “yes”, unless it can be determined that certain areas did not have the distribution pressure drop to the point that appliance utilization pressure was affected.)
 Have all affected meters been shut off and marked? Calculation to determine total hour requirements for shutdown only: Number of customers to shut down divided by 12 (average meters that can be shut off in one hour by one service person), equals the total hours required to shut down the system. If you divide the number of service persons by the total hours required, it will indicate the approximate amount of time (in hours) that the shutdown process will take. Example:
Analyze the total time required for shutdown to determine if outside or mutual assistance is required. If the total shutdown time will take 48 hours, yet the repairs will only require 8 hours, consider calling for assistance so that the shutdown is performed in a timely manner.
 Is outside construction area assistance required for shutdown?

 Has 24-hour rep / desk been notified of a gas customer outage?
 Can complete restoration of service be accomplished with available personnel in a reasonable period of time? Calculation to determine total number of personnel required to accomplish restoration of service: Number of customers out of service divided by 4 equals the approximate number of hours required to restore service. Divide this figure by the number of existing field personnel available in the area to determine the average hours per person required. This figure may then be divided by the number of complete 16 to 20-hour shifts (days) required to restore the system. Mutual assistance may be required if the time requirements are out of tolerance due to weather, critical customers, etc.

Equals total hours required by person = Hours per person = 5
Divide by shift hours ÷ Shift ÷ 16
Equals the approximate number = Days = .3
Note: This calculation is only a guideline and should be reviewed by the Incident Commander, the Gas Operations Manager, or technical management support. The decision to initiate for inside Company assistance shall normally be made by the Operations Manager or technical management support.

GAS EMERGENCY AND
SERVICE HANDBOOK

SECTION 7 METER TURN-ON ORDERS
GENERAL Gas service persons shall perform gas meter turn-on orders on existing meter installations in accordance with the applicable filed tariff. Turn-on orders performed after hours, weekends, and holidays may be subject to a customer charge.
Required Information Turn-on orders shall be issued on the appropriate gas operating order and shall specify information required to open the customer account. This information includes customer's name, complete address (with apartment unit number, as necessary), meter number, meter location, date scheduled, date and time order taken, time arrangements, etc. Completed orders shall contain the meter read, and notes on the conditions found and work performed.
Turn-On Originated in the Field
The gas service person may originate a meter turn-on order in the field. The service person shall obtain all required customer information and shall advise the customer that they must contact the Customer Services Department to complete the application for service. A comment shall be placed on the gas operating order to notify the Customer Services Department of the new customer.
Meters Found On By Serviceman In cases where the meter has been found on by the person performing the service work, an attempt shall be made to gain access to inspect the equipment for safe operation. If access is gained, complete the documentation. If access is refused or the Avista responder cannot gain entry, the meter shall be spot checked. If there is flow greater than or equal to 4 CFH and it cannot be confirmed from outside the premises that the usage is reasonable, the meter shall be shut off and locked at the service valve due to unaccountable gas flow. Issue a hazard notice with the reason being “Unaccountable Gas Flow”. A “Field Request-Miscellaneous-Shut off Meter” order shall be generated for the meter premises. Completing this order will ensure appropriate customer follow-up communications are completed. Additionally, document the access refusal or can’t gain entry situation on the gas operating order. If the flow is less than 4 CFH, the meter may be left on at the Gas Serviceman’s discretion. Document the actual amount of gas flowing through the meter and advise the customer of this situation.
Can’t Gain Entry Situations
If the customer is not home for completion of the turn-on order, the meter shall be left locked-off at the service valve and the service person shall leave the appropriate Can't-Gain-Entry notice on the premises.

METER TURN-ON ORDERS
GAS EMERGENCY AND
SERVICE HANDBOOK

Meter Off but Access Refused If a customer refuses Avista access inside their home or business to safety check the equipment, the Gas Serviceman shall strongly advise the customer to have a dealer perform the relight. The meter shall be left off at the A-9 (downstream) valve. It there is not an A-9 valve present, one needs to be installed and turned off. In the event an A-9 valve cannot be installed at this time, the meter shall be shut off and
locked off at service valve. Document the need to return to install an A-9 valve in the Gas Operating Order. DO NOT spot check the meter and leave it on. Duplicate Orders
When the service person finds that the meter has been turned on for a new customer on a previous service order, the meter reading and date shall be noted on the gas operating order. The order shall be noted as a duplicate order in comments. METER TURN-ON PROCEDURES The service person shall determine if the customer is home and/or if access is available to all gas equipment before unlocking and turning on a meter. Access for service must be made available by a responsible adult, 18 years of age or older.
Determination of BTU Load
The customer's equipment BTU load shall be checked, and it shall be determined if the existing meter capacity is sufficient for that load. If it is determined that a larger meter is required, the service person shall make arrangements to have the appropriate size meter installed as soon as possible. In cases
where there is a large commercial or industrial load that requires additional capacity, the order shall be referred to the Gas Meter Shop and/or Gas Engineering Department for proper sizing. Meters that are too large for the existing load shall be removed and the appropriate size meter shall be installed before turning on the gas service.
Under Sized House Piping
If it is determined that the customer's house piping system is insufficient for the existing load, the customer can be assisted using the house piping sizing chart (refer to Gas Standards Manual, Specification 3.16, Services). In most cases the customer will be referred to a dealer or contractor to correct the pipe sizing problem. (Pressure drop on 7-inch WC systems should not exceed 0.5 inches WC at the most remote locations on the system. Pressure drop on systems operating at elevated pressures should not exceed 10 percent of the delivery pressure.) Such conditions shall be documented on the appropriate hazard notice and on the gas operating order. Bringing Meters up to Standard
Gas meters should be brought up to standards any time there is an opportunity. Bringing up to standard means in accordance with standard meter set drawings in the Gas Standards Manual, Specification 2.24, Meter & Regulator Tables & Drawings, including and above the service valve or as approved by the Gas Design Manager. A PE riser does not require changing to an insulated service valve, however per Specification 3.16 an insulated valve is preferred. (This does not include work to the riser itself, tracer wires, sleeves, etc.) The A-9 valve is the preferred downstream device for AC250, R275, and AL425 meters, however, a bypass tee or other similar device are acceptable alternatives.

METER TURN-ON ORDERS
GAS EMERGENCY AND
SERVICE HANDBOOK

Except in the case of large outages, if a meter is not brought up to standard, it shall be documented as to the reason for not doing so. Meters showing evidence of leakage, damage, or corrosion shall be replaced or repaired, as appropriate. All leakage discovered on the meter set assembly shall be corrected before completing the turn-on order. Meters that are in contact with the soil shall be raised to an aboveground level, or other provisions shall
be made to eliminate such contact.
Meter sets that are not level or that are in a bind shall be rebuilt to the standard configuration. If the work cannot be completed before turning on the gas, a follow-up order shall be issued for completion as soon as practical. In cases where the customer's house piping is causing the condition, the gas service should be left off until the customer arranges to have the condition repaired by a dealer or contractor. Bypasses should be installed before the gas is turned on. Note the conditions on the appropriate hazard notice and on the gas operating order.
Utilization Pressure Check Requirements
The utilization (flow) pressure shall be verified for all meter turn-on orders where a disassembly of the MSA occurs. This includes but is not limited to regulator change outs, periodic meter changes (PMC’s), other meter changes, damaged service line customer reinstatement, and service / service tee work that results in a customer shutdown.
Utilization Pressure Check (Inches WC) When verified, the utilization pressure (in inches WC) shall be checked at the outlet of the meter using a water manometer or an appropriately calibrated gauge. Unless otherwise specified, the outlet flow pressure shall be set at 7-inches WC with a representative load. For AC-250 meters, the flow can be checked with a stab cone downstream of the meter using an approved apparatus which is a 20LT swivel with a #19 drill bit hole, representing approximately 100,000 BTUs flowing through the meter. The regulator should lockup promptly, and not build pressure. Lockup pressure shall not exceed 2-inches WC above the set flow pressure. Note: Multi-meter manifolds and master meters are exempt from the mandatory lockup pressures, but flow pressure is required. Commercial and Industrial customers are exempted as well from lockup pressures if a complete shutdown is impractical at the time. Document these exceptions on the gas operating order. Utilization Pressure Check (2 and 5 PSIG)
When verified, the utilization pressure for 2 psig and 5 psig meter set pressures shall be checked at the
outlet of the meter using an appropriate gauge. The outlet flow pressure shall be set with a representative load flowing through the meter. The regulator should lockup promptly and not build
pressure. Lockup pressure shall not exceed 50 percent above the set flow pressure or the relief setting of the regulator (or relief valve), whichever is lower. In no case shall the lockup pressure exceed the customer piping test pressure. (Refer to note above on exceptions to taking lockup pressures.)
Non-Conventional Utilization Pressure Check
When verified, the utilization pressure for non-conventional delivery pressures shall be checked at the outlet of the meter using a calibrated spring gauge or with a calibrated digital pressure gauge. The outlet
flow pressure shall be set in accordance with the service order and correction code. Utilization pressures greater than 7-inches WC through 12 psig shall have a regulator lockup pressure that does not exceed 50
Staff_PR_007 Attachment A Page 82 of 133
METER TURN-ON ORDERS
GAS EMERGENCY AND
SERVICE HANDBOOK

percent of the utilization pressure. Utilization pressures greater than 12 psig shall have a regulator lockup pressure that does not exceed 6 psig over the utilization pressure. In no case shall the lockup pressure exceed the customer piping test pressure. (Refer to note above on exceptions to taking lockup pressures.) Service Order Completion
Flow and lockup pressures shall be recorded on the appropriate gas operating order. Pressures shall be
verified against the existing meter correction code as indicated on the customer account and/or service work order. Regulator Validation
Company regulators that are not operating properly shall be repaired or replaced before completing the
turn-on order. Pressure problems that are determined to exist on the customer's house piping system shall be referred to a dealer or contractor to have the piping problem corrected and the meter shall be left
locked off. Note the conditions on the appropriate hazard notice and on the gas operating order. The service person should make an effort to leave the gas service on if this can be accomplished by isolating a section of house piping that is causing the pressure problem. The appropriate hazard notice
shall be issued, and the conditions found, and left shall be recorded on the gas operating order.
House Piping Leak Test
After turning on a meter, the gas service person shall perform a leak test of the customer's house piping system. Appliance burners and pilots shall be closed, but the appliance shutoff valves should be left on
(this will test for leakage up to the controls). The meter shall be tested to make sure that the test hand registers. The leak test shall then be performed in accordance with the Meter Spot Check requirements
as outlined in GESH, Section 2 - Leak and Odor Investigation.
When a leak is found that is not readily repairable, the procedures outlined in GESH, Section 2 – Leak and Odor Investigation shall be followed.
Purging
After turning on the meter, the service person shall safely purge the meter, house piping, and gas
equipment of air. The service person shall use caution during the purging procedure and shall maintain alertness for potential sources of ignition. If practical, purging should be done through the appliance
pilots as opposed to opening a union or connector.
Servicing Gas Equipment
Gas equipment connected to the house piping system shall be serviced according to the service policy as outlined in GESH, Section 10 - Gas Equipment Service – Hazardous Conditions. All work done and conditions found shall be recorded on the gas operating order.
Inaccessible Equipment
Gas equipment should be accessible for servicing before the gas may be turned on. In cases where the gas equipment is not accessible, the customer should be advised to provide safe access, and to call to re-schedule the turn-on order when access is available.

METER CHANGE/REMOVAL ORDER
GAS EMERGENCY AND
SERVICE HANDBOOK

SECTION 9 METER CHANGE ORDER / METER REMOVAL ORDER
GENERAL Gas meters are normally changed to comply with regulatory testing and proving requirements (PMC's or Periodic/Planned Meter Changes). Other reasons for meter changes are changes in load requirements (upsizing or downsizing), changes due to damage or leakage, changes due to suspected diversion, etc. Gas meters are normally removed in cases of non-use or in instances where impending construction or demolition requires removal of the meter and service. Required Information
Meter change and removal orders shall be issued on the appropriate gas operating order. The service order shall indicate the customer's complete name, full address (with apartment or unit number), meter number and location, as well as the time and date the order was taken, and any access arrangements. Service persons unable to complete a meter change or removal order due to insufficient information shall contact the Gas Control Room (by calling 509-495-4859 or via radio) or Service Dispatch, as applicable, for instructions and shall note the conditions on the gas operating order. Completed meter change or removal orders shall indicate the arrival and departure times, as well as comments on conditions found and work performed. Incorrect Meter Number
If it is discovered that the meter number on the meter change or remove order is different from the one at the customer premises, the service person shall contact the dispatch office to determine the correct location and meter number. Meters shall not be changed or removed unless the correct meter number and premise location are verified.
Inaccessible Meters If a meter to be changed or removed is inaccessible, the service person shall make a reasonable attempt to contact the customer by phone (if a number is available on the service order). If the customer cannot be reached for access, the service person shall leave the appropriate Can't Gain Entry (CGE) notice on the premises and shall note the gas operating order accordingly. Existing Meter Sets Existing meter sets downstream of steel pipe systems, isolated risers or manufactured service risers (all risers except non-corrodible risers) shall be insulated when performing routine meter set work or when a meter is changed out. If non-insulated meter sets served by steel pipelines are found during other routine work, the meter set shall be insulated immediately, if practical, otherwise an order shall be issued to insulate the meter set within two working days. When practical, valves downstream of a non-corrodible riser should be insulated similar to valves on steel pipe systems.

METER CHANGE/REMOVAL ORDER
GAS EMERGENCY AND
SERVICE HANDBOOK

Checking For Electrical Shorts When performing work at or visiting a meter set, a visual examination shall be made to determine if an electrical short could occur due to any of the following conditions:
• House piping in contact with the meter set piping upstream of the insulation fitting.
• Regulator vent lines grounded to the building (where they would be upstream of the insulation fitting.)
• Service valve or other inlet side piping in contact with the meter body.
• Meter body in contact with the ground or the building.
• Foreign metallic objects in contact with the meter set assembly (bicycles, pipes, chains, sheet metal, etc.)
• Foreign wires attached to the riser or meter set piping (ex. grounding wire).
If any of the above conditions are found, the condition shall be corrected, or the objects removed to
prevent electrical shorts. If customer materials or circumstances prevent immediate correction of the condition, the customer shall be advised that they are required to keep the meter set clear of metallic and
electrical interference, and that the condition must be corrected within 2 weeks. The appropriate notice shall be issued and left with the customer. The conditions found and actions taken shall be noted on the
appropriate gas operating order, and the order shall be noted for follow-up. Grounding of Meter Sets if Necessary
In cases where a voltage potential (other than a Company impressed current) is found to exist on a meter set, steps shall be taken to ground the meter when performing work and to ultimately remove the source
of the electricity. (Normally, this situation occurs when there is a defect in either the customer's house electrical system or when there is an electrical short at a gas appliance.) If the source cannot be readily located, the customer shall be referred to an electrical dealer or contractor to locate and correct the condition and the appropriate unsatisfactory notice shall be issued. If the situation is hazardous, the customer shall be advised to close the electrical service until repairs can be
made. Conditions found and actions taken shall be recorded on the gas operating order. METER CHANGE ORDERS
Contacting the Customer
Meter change orders should be completed by use of a bypass device if the meter set assembly is equipped with bypass capabilities. In cases where the meter must be turned off to complete the meter change, the customer should be contacted and informed of the action to be taken. The customer's schedule should be taken into consideration when attempting to complete meter changes (if no leakage or hazard is involved). Meter changes for commercial or industrial customers may require to be scheduled around periods of peak use.
Meter Change Originated in the Field
A meter change order may be originated in the field. The appropriate gas operating order shall be prepared indicating the address of the change, the reason for the change, the date and time completed, as well as complete information on the old and the new meters.

• A positive indication that there is odorant present in the gas at this location.
Customer Not Home – Inside Set
Meter changes on meter sets that are inside a customer’s building shall be incomplete if the customer is not available and inside access is not attainable. A reasonable attempt should be made to contact the customer by phone (if a number is available on the gas operating order). If the customer cannot be contacted, the appropriate Can't-Gain-Entry (CGE) notice shall be left on the premises advising the customer to call to schedule an appointment to change the meter.
Customer Not Home – Outside Set Where meter sets are outside, consideration should be given, as appropriate, to notify the customer before a meter change is performed (except in cases of leakage or mechanical difficulty). If the customer is not home and a bypass cannot be performed via an A-9 valve or other accommodation, the appropriate Can't Gain Entry (CGE) notice shall be left on the premises advising the customer to call to schedule an appointment to have the meter changed. If, after the first notice, the customer does not call to schedule, the meter may subsequently be changed, and the service valve locked off. An appropriate Gas Shutoff notice shall be left advising the customer to call to have the service turned back on. Cold Weather Precautions In cold weather, the meter shall not be left off if there is the possibility of freeze-up. If the meter has already stopped, if leakage exists on the meter set that must be repaired or if there are other situations that require immediate shutdown, the meter may be left off. In these cases, the service valve shall be locked off, and the appropriate Gas Shutoff notice shall be left on the premises. In addition, the service person shall make a reasonable attempt to contact the customer by phone to make arrangements for prompt restoration of service. All conditions shall be noted on the gas operating order. Determination of BTU Load Before completing the meter change, the customer's BTU load should be checked, and it should be determined that the existing meter capacity is sufficient for the existing load. If it is determined that a
larger meter is required, the service person shall make arrangements to have the appropriate size meter installed as soon as possible. Meters that are determined to be too large for the existing load shall be
removed as well and the appropriate meter size installed. If the appropriate meter size cannot be calculated in the field, the Gas Meter Shop or Gas Engineering Department should be consulted.

BYPASSING PROCEDURES – GRUNSKY METER CHANGING DEVICE
General Information The following procedures apply only to the meter-changing device manufactured by the Charles Grunsky Co. This device utilizes compressed natural gas to temporarily supply gas to a customer through the use
of the outlet tee on the meter set assembly. Insertion of the Grunsky probe into the outlet tee allows the customer's house piping to be supplied, while at the same time blocking off flow back through the meter set. The service valve can then be closed allowing the field person to complete the meter change or other maintenance. Compressed natural gas may be supplied from the service truck mounted CNG cylinders individual cylinders mounted on hand dollies, a portable Grunsky device (using a 20 cf “pony” bottle) or from a CNG trailer.
The Grunsky device is intended for temporary, attended use only and should not be used in confined
areas or close to potential sources of ignition. The device may only be used to supply gas to customers at 7-inches WC. Elevated pressure meter sets require alternate bypass capabilities. Bypassing Procedures
The procedures for using the device are as follows: 1. Check to make sure that the CNG source is filled and that you have sufficient capacity to complete the operation. Attach the proper size probe to the device. (The probe must fit the size of the outlet meter tee.) Check that the supply hose length will reach the meter set without causing a hazard.
2. Connect the supply hose. If using a CNG source with multiple bottles, check that all of the bottle supply valves are “on”. 3. Close the feed valve on the probe assembly and connect it to the supply hose. Open the feed valve to allow a small amount of flow and set the high-pressure regulator at 30 to 50 PSIG. Set the low-pressure regulator to 7 inches WC (or as required). Purge the air from the hose and close the feed valve. 4. Loosen the plug in the outlet tee with a wrench until finger tight. Do not remove the plug at this point. 5. Install the rubber bag over the end of the tee. Make sure that it fits tightly. 6. Turn on the feed valve, open the bag valve and purge the air through the valve on the bag by squeezing the bag several times. Close the bag valve. 7. Remove the tee plug through the bag with your fingers and allow the plug to drop into the bag. (At this point, gas is being supplied from both the service and the CNG cylinder.) 8. Insert the probe into the nipple downstream of the outlet tee. (Do this by inserting the head of the probe into the tee, then on into the nipple.) Twist the probe to obtain a satisfactory friction fit. Observe the pressure gauge. Gas is now being supplied from the CNG cylinder only.
9. Close the service valve. 10. Open the valve on the rubber bag. Gas will momentarily purge from the meter set through the bag. If purging continues, the probe is not seated properly.

METER CHANGE/REMOVAL ORDER
GAS EMERGENCY AND
SERVICE HANDBOOK

11. Perform the meter change and/or maintenance work. Avoid disturbing the probe assembly. (If the probe is accidentally knocked loose, assume that the house line pressure has been dropped and the pilots have been extinguished. Close the feed valve and attempt to gain access to relight the gas equipment. If the customer is not home, close and lock the service valve and leave the appropriate Gas s hut-off notice on the premises.) 12. When the work is completed, turn the service valve on slowly. The bag should inflate indicating
that gas is passing through the meter. Allow the meter set to purge, then close the valve on the bag.
13. Soap test the meter set before removing the probe. Any other leaks can be repaired while still on bypass. 14. Twist the probe slowly and pull on it until the head is removed from the nipple and tee. Be careful not to remove the bag. (Gas is now being supplied again from the service and the CNG cylinder.) 15. Locate the plug in the rubber bag and insert it finger tight into the outlet tee. (Performing this operation may take a little practice.) 16. Close the feed valve and open the valve on the bag to deflate it. Remove the probe assembly. 17. Apply pipe dope to the exposed threads of the plug and tighten it with a wrench. 18. Re-check for leaks.
19. Close the supply valve on the CNG source. METER REMOVE ORDER
Contacting the Customer Before removing a gas meter, the customer shall be contacted and informed of the action to be taken. In cases where the building is obviously vacant or where the meter must be removed for construction or demolition, the meter shall be removed immediately. In cases where the meter has been locked off for a period of over 12 months and the customer is unwilling to open the account and pay the monthly fee, the meter shall be removed.
Meter Removal Originated in the Field A meter remove order may be originated in the field. The appropriate gas operating order shall be prepared indicating the address of the removal, the reason for the removal, the date and time completed, and a forwarding address for the customer (if necessary). The meter number and reading shall also be recorded on the service order. Typical reasons for issuance of a field order are as follows:
• A meter is found disconnected.
• A building is being demolished or moved.
• Major alterations are being performed and the meter must be removed to prevent damage.
• Where it is evident from information obtained in the field that the use of gas has been discontinued.

SPECIAL CONCERNS Unvented Heaters and Decorative Appliances Due to the variation in national code viewpoints on unvented heaters and decorative appliances, Avista Utilities service persons shall adhere to the following policy on unvented heaters and decorative appliances when performing safety inspections:
Washington Idaho Oregon
Appliances (Fireplaces) Allowed (Note 2) Allowed (Note 3) Allowed (Note 4)
Note 1: Not allowed as state of Washington adopts the 1997 UMC (with Washington amendments which constitutes the Washington Mechanical Code) which requires heating appliances to be vented to the outside. Note 2: Amendment to the Washington Mechanical Code allows the use of unvented decorative appliances with certain installation and operating conditions. Note 3: The state of Idaho has adopted both the Uniform Mechanical Code and NFPA NO. 54, the Fuel Gas Code. The UMC disallows unvented equipment, while NFPA No. 54 allows for both unvented room heaters and decorative appliances. The state of Idaho makes an exception to the UMC in allowing for the installation of unvented equipment as specified in their listing and in NFPA No. 54. This rule applies to Idaho gas utilities only. Individual governmental jurisdictions may not allow unvented heaters. Note 4: The state of Oregon has adopted the One and Two Family Dwelling Code as published by CABO. The CABO code does allow for unvented gas appliances if they are listed for this use.

Responding to Pressure Alarms Company field personnel shall respond to pressure alarms on Avista’s pipelines, generated by telemetry equipment that may indicate a potential safety problem. The field personnel shall verify the pressure condition on arrival using a pressure gauge known to be in calibration. Additionally, the Avista Gas First Responder should work with the Control Room (by calling 509-495-4859 or via radio) (as applicable) to
evaluate the event history logs for further information to assess the risk that over-pressuring or under-pressuring may have occurred. The pressure charts connected to the system in question should be
reviewed to help with assessment. Control Room personnel may choose to involve Telemetry Technicians and/or the Telemetry Engineer if the situation warrants further expertise. Communications with the Interstate Pipeline’s Control Room should be initiated by Avista’s Control Room personnel. Low Pressure Alarm: Loss of pressure that may have extinguished pilots or that may have affected the normal operation of the customer’s gas equipment shall be treated as an outage and the procedures followed as outlined in GESH, Section 5 – Emergency Shutdown and Restoration of Service which addresses emergency shutdown, pressure reduction, and restoration of service. High Pressure Alarm: Verify the maximum allowable operating pressure (MAOP), if it is determined that a system has exceeded the MAOP; the employee shall immediately attempt to correct the situation and normalize the pressure. At a City Gate Station where the pressure is regulated by the gas supplier, contact shall be made with the appropriate gas supplier to coordinate any adjustments on their facilities to normalize the pressure. If the pressure is excessive (i.e., more than 10 percent of the MAOP), the downstream facilities must be checked for damage including regulators, piping, and any other auxiliary equipment in the vicinity of the pressure exceedance per §192.741(c). The Gas Control Room shall notify the On-Call Gas Engineer if either of the above-mentioned situations occur as this may necessitate an incident notification to the appropriate state and/or federal regulatory agency. Additionally, the On-Call Engineer shall consult with the Gas Design Manager as to other actions that should be taken to evaluate if additional downstream inspections are warranted and if any setpoint changes or design modifications are necessary. Mutual Assistance
A Mutual Assistance Agreement is an agreement among gas utilities to supply assistance in the form of materials, equipment, and labor to a member company during times of emergencies, such as floods, earthquakes, and outages. The American Gas Association (AGA), Western Energy Institute (WEI), and others facilitate mutual assistance efforts by maintaining lists of member companies. Additional details are noted in the Gas Standards Manual, Specification 4.31, Operator Qualification, “Mutual Assistance Agreement”. Qualified individuals responding to Avista in a mutual assistance situation shall be utilized as outlined in Avista’s Operator Qualification Plan.
Cold Weather Action Plan
Avista’s Cold Weather Action Plan (CWAP) is a separate document that is maintained and updated by the Gas Planning Engineer. The document can be found on the Gas Planning SharePoint site. The purpose of the CWAP is to put forth processes and procedures to help mitigate the chance of low pressure in
areas that are awaiting pressure reinforcements. Actions are initiated when certain temperature triggers are reached.

Snow Action Plan Avista’s Snow Action Plan (SAP) is a separate document that is maintained and updated by the Gas Planning Engineer. The document can be found on the Gas Planning SharePoint site. The purpose of the SAP is to put forth processes and procedures to help eliminate the possibility of snow damaging aboveground gas facilities. Actions are initiated by local area management when accumulated snow
reaches certain predetermined conditions.
Pre-Construction Emergency Planning for Road Projects Road construction project notices and plans sent to Avista from any city, county, or state entity should be evaluated. Projects found to be near Avista’s facilities should be reviewed to decide if a pre-construction emergency plan is needed. Preplanning for anticipated events can help ensure successful control and management of an incident and should be performed whenever possible. Recommended personnel
responsibilities and workflow should be as follows:
Road Construction Coordinator or Customer Project Coordinator (CPC): 1. Receives notice of future construction projects. 2. Determines project scale and area of construction. (e.g., urban, suburban, or rural). Also notes
significant customers, hospitals, schools, etc. 3. Reviews existing EOP zones within the construction project to determine if a pre-construction
EOP plan is needed. 4. Forwards the project to Operations if a pre-construction EOP plan is needed.
Operations:
1. Determines location of all valves necessary to isolate the involved EOP zone(s) and to execute
the pre-construction emergency plan. 2. Reviews gas facility sizes, types and any pressure issues that might impact the project.
3. Traces supply of natural gas feeds into the project area (Gas Control Room to assist as necessary).
4. Determine if EOP zone size is manageable should damage occur during the project. 5. Works with Engineering and Compliance Techs (as applicable) to install street valves at strategic
locations if the construction zone is deemed too large. 6. Sends newly installed valve documentation to the Editor and Compliance Tech.
7. Sends the completed preconstruction emergency plan packet to the Gas Control Room and Engineering for review and familiarization before construction begins.
8. Performs an on-site pre-construction safety meeting to discuss gas facility damage prevention and response with the Road Project Contractor’s personnel to include equipment operators.
Curtailment Rules
Operations Managers, supervisors, gas controllers, and Avista Gas First Responders should be knowledgeable of and consider Avista Gas Tariff Curtailment Rules when implementing emergency operations. The following tariff requirements shall be adhered to:
ID – Rule No. 182 (IPUC No. 27) “Contingency Plan for Firm Service Gas Curtailment”

GENERAL Gas service persons shall maintain alertness for evidence of unauthorized use or diversion of natural gas. Natural gas supplied to Avista Utilities customers shall be metered. Attempts to bypass such metering or to utilize gas without intent to pay for it constitutes theft of service.
Reporting Diversion of Service Actual or suspected diversion cases shall be reported to the Billing Department for follow-up as soon as possible via phone [phone]) or email (#[e-mail]). The conditions found shall be documented on the appropriate gas operating order. Information required includes the customer name, address, meter number, meter reading, date and time of discovery, seal number (if any), and a description of the conditions found, and action taken. Photographs should be taken of the meter set or affected piping before any action is taken to disassemble the bypass or related piping and fittings. The Billing Department shall be contacted via phone [phone]) or email (#[e-mail]) for instructions after the initial information is obtained from the field. The customer should not be contacted until the Billing Department has been informed and the suspected bypass assembly has been photographed. If the customer is contacted, the service person should be careful not to accuse or malign the customer in regard to the suspected diversion. If in doubt, wait for instructions from the Billing Department or supervision. REQUIRED ACTION
Tampering and Illegal Bypasses In cases where blatant tampering is evident (index tampering, handhole cover removed, meter installed backwards, etc.), or an actual illegal meter bypass situation exists, do not attempt to correct the situation until all circumstances are documented, photographed, and the Billing Department is notified via phone [phone]) or email (#[e-mail]) If an immediate safety hazard exists, the meter shall be turned off and the service valve locked with a padlock until the conclusion of the investigation. The labor performed and materials used during the course of the investigation and during the course of any required repairs shall be documented on the appropriate gas operating order for possible future billing.
Missing Meter Seals Missing meter seals may or may not be evidence of tampering. In lieu of information indicating actual tampering, the seals shall be replaced. The facts shall be documented on the appropriate gas operating order and a copy sent to the Billing Department for possible follow-up.
Broken Locks Company meter locks that have been removed or broken off shall be replaced. If the gas service is found on in such cases, the meter shall be closed, the lock replaced, and a blank tin disc installed in the outlet side of the meter. The Billing Department shall be notified via phone [phone]) or email (#[e-mail]) and the circumstances documented on the gas operating order. The Billing Department shall determine if other measures are necessary to prevent further theft, such as removal of the meter.

SECTION 16 HIGH BILL INVESTIGATIONS AND CUSTOMER REQUESTED METER TESTS
GENERAL
Customer Service Responsibility In general, Customer Service (Contact Center) is primarily responsible for the initial investigation and the ultimate resolution of any High Bill Inquiry or billing question initiated by customers of Avista Utilities. Customer Service Representatives (CSR) shall make every effort to answer all questions regarding billing and Company operations and shall attempt to resolve all issues to the satisfaction of the customer. It should be recognized that not all high bill inquiries constitute "complaints". Many customers are simply unclear as to Company billing procedures or may not be familiar with a recent rate increase. In many cases, the inquiry is of definite benefit to the customer and the Company as potentially serious conditions can be detected and corrected before damage occurs (i.e., house piping leakage, equipment malfunction, etc.) A High Bill Inquiry that cannot be answered to the customer's satisfaction, inquiries that indicate unusually high gas consumption (taking into account past usage and weather conditions), or “Customer Requested Meter Tests” should be followed up with a field order. Customer Requested Meter Test
The customer may request that their meter is tested in association with a High Bill Inquiry. When requested by the customer, a meter test should be conducted in conjunction with a Field Order and an appropriate High Bill Investigation Field Order completed in addition to the test. “Customer Requested Meter Tests” shall be resolved within 20 days and in accordance with applicable laws.

OAR 860-021-0130
Any customer may ask the energy utility to test a meter. Such tests shall be made within 20 working
days of the request at no cost to the customer. If a customer requests more than one meter test within
any 12-month period, the energy utility may charge the customer to recover the reasonable cost of the
test. The energy utility may not charge the customer if the meter is found to register outside the 2 percent accepted tolerance standard under normal operating conditions.
A customer and/or a designated representative shall have the right to be present at any meter test.
The test shall be conducted at a mutually acceptable time during regular business hours.
A written report showing the customer's name, the request date, the address where the meter has
been installed, the meter's number, the date tested, and the test result shall be supplied to the
Staff_PR_007 Attachment A Page 118 of 133
HIGH BILL INVESTIGATIONS
GAS EMERGENCY AND
SERVICE HANDBOOK

Meters to be tested shall be investigated by a qualified person and as-found field conditions denoted on the meter as detailed below. If requested by the customer the meter shall be sealed, opened, and tested
in the presence of the customer or the customer’s representative. Customer requested meter test results shall be reported to the customer within 20 days of receiving the request. Avista Initiated Meter Test
In addition to a customer requested meter test, a meter test may be initiated by Avista service personnel
in accordance with a field investigation and to facilitate resolution of a high bill inquiry. The meter test should be conducted in a similar manner as a customer requested meter test except that the resolution
does not require a customer notification of the test results. The results, however, may be shared with the customer to facilitate resolution of the high bill inquiry.
WAC 480-90-183
(1) A gas utility must test and report to the customer the accuracy of a meter within 20 business days
after receiving an initial request from a customer. The utility must allow the customer to order one
meter test free of charge during a 12-month period. The utility may appeal to the commission to waive
the responsibility of performing the meter test, to request an extension to perform the meter test, or to
be allowed to charge for the meter test. If the customer disputes the accuracy of the meter, the
customer must allow the utility access for meter testing.
(2) The customer may, at the customer's option, either witness the meter test or designate a
representative to witness the test. The customer may require the meter to be sealed upon removal in
the presence of the customer or the customer's representative. The seal must not be broken until the
test is made in the presence of the customer or the customer's representative, or until permission to
break the seal has been granted by the commission. The utility must report the results of the meter
test to the customer.
(3) A customer may request the utility to perform additional meter tests within 12 months of the last
meter test, but additional meter tests will not delay disconnection of service under of
WAC 480-90-128(9), Disconnection of service. The utility must immediately inform the customer of
any additional meter test charges. If the customer elects to have the meter test performed, the utility
must perform the test and report the test results to the customer within 20 business days. If the
additional meter test results show the meter is performing accurately as defined in
WAC 480-90-338, Metering tolerance, the utility may charge the customer for performing the
additional meter tests. The charge of the meter test must be listed in the utility's tariff. The utility may
not charge the customer for any additional meter test that shows the meter is performing outside acceptable tolerance levels as defined in WAC 480-90-338, Metering tolerance.
(5) If a meter test reveals a meter error greater than specified as acceptable in WAC 480-90-338,
Metering tolerance, the utility must repair or replace the meter at no cost to the customer. The utility
must adjust the bills to the customer based on the best information available to determine the
appropriate charges. The utility must offer payment arrangements in accordance with WAC 480-90-

SERVICE HANDBOOK

SECTION 17 GAS INCIDENT FIELD INVESTIGATION
GENERAL Avista Utilities gas field employees and supervisors shall be familiar with the field investigation procedures as outlined in this Section and shall adhere to these procedures when responding to suspected gas related incidents, accidents, failures, or fires. Adherence to standard field investigative techniques when responding to these situations will help to maximize public safety and minimize risk to Company personnel. Avista Utilities personnel shall utilize the Gas Incident Field Checklist and the Gas Occurrence Review Flowchart at the end of this Section when responding to all incidents. Responses and Notifications
Avista Utilities will normally be informed of any suspected gas related incident either by the customer, emergency services, or by other employees. Field response to such incidents shall be delegated to Journeymen Gas Service Persons, Local Representatives, Journeymen Mainfitters, or other qualified persons that have been trained in emergency response and that have the appropriate tools and equipment available to perform field leak investigations (including a Combustible Gas Indicator and bar hole probe). These qualifications, tools, and equipment are outlined in GESH, Section 2 - Leak and Odor Investigation. Additional personnel from other departments may be dispatched simultaneously to assist with the investigation, collect data, take photographs, dispense information, or provide supervision. The gas service person shall call the Gas Control Room at (509-495-4859 or via radio) immediately to notify the Gas On-Call Engineer, Claims Department, Corporate Communications, and others as appropriate when it is suspected that the incident involves any of the following:
• Failure or malfunction of material/component
• Noticeable trends (multiple occurrences)
• Gas related fire or explosion
• Lightning Strike / Electric Arcing
• Loss of life/personal injury
• Fire that is not gas related, but that affects Company facilities.
• 3rd party damage that results in any of the above conditions and/or involves over $25,000 of damage ($5,000 in Oregon). (Note: Federal reporting occurs at $129,300 but Claims is interested in being notified if damages will likely exceed $25,000) If the Gas Service Person responds to any order that involves personal injury, hospitalization, or death (even if it does not directly involve Company facilities), the service person shall also follow the complete
fire or explosion procedures for investigating gas-related incidents as outlined in GESH, Section 2 - Leak and Odor Investigation, and Section 4 - Emergency Procedures. While the customer's equipment and
downstream piping is the customer’s responsibility, it is important to perform as many checks as possible to document the scene and provide maximum public safety.
(Refer to GESH, Section 13 – Emergency Planning, Training, and Incident Notification for additional reporting requirements.)

GAS INCIDENT FIELD INVESTIGATION
GAS EMERGENCY AND
SERVICE HANDBOOK

Utilizing the guidelines as listed on the Major Gas Incident Report (Form N-2566); the field person on the scene shall provide enough initial information to the On-Call Gas Engineering person and Claims so that state or federal reporting requirements are satisfied. The On-Call Claims Department Representative can be reached at 509-495-4357 or 800-727-9170, ext. 4357. Chain of Custody
In all cases, it will be necessary to obtain the consent of the official (or lead investigative authority) in
charge of the site and Claims to disconnect and/or remove any form of evidence. Gas meters, meter set components, and other gas facilities are the property of Avista Utilities and shall be initially retained by Company personnel, then tagged for identification and transported to Company facilities for safekeeping as outlined in this Section. It is preferable that a representative from the Claims Department transport any evidence, if practical. If
Claims is unavailable to transport the facilities, the employee removing or transporting the facilities shall contact the Claims Department to determine the location of the appropriate secured facility for storage.
The on-call Claims Department Representative can be reached at 509-495-4357 or 800-727-9170, ext. 4357. The operator must keep the facility intact until directed by the lead investigative authority. After testing and analysis is complete, the Claims Department shall retain custody of the meter set or other evidence in the secure lockup until it has been determined that the evidence is no longer needed.
Controlling Emergencies
The gas service person shall evaluate and attempt to control any existing emergency (Refer to GESH,
Section 4 - Emergency Procedures) before engaging in any data collection or investigative actions. The incident commander or other emergency services official in charge of the site shall be notified upon
arrival, when the emergency condition is controlled, and prior to entering any fire or explosion site to collect data, remove meters, etc. In most cases, it will be necessary to obtain the consent of the official
(or lead investigative authority) in charge of the site and Claims to remove any form of evidence or to disturb the site in any way. In some cases, access may be temporarily restricted if the incident
commander feels that the service person may be put in harm's way. Incident commanders shall be notified immediately if it is apparent that the service person needs access to the site to prevent further
danger or to complete the assessment of the problem. (One example would be the immediate need to enter the restricted zone of a structure fire if the service person has reason to believe that natural gas
may be migrating to the area, or if it is suspected that gas may be feeding the fire.)
Preliminary Data Collection
If it has been determined that the incident is gas related (or if it falls under any of the guidelines (listed above), the gas service person shall initiate an investigation and obtain the following information as soon
as possible:
• Meter number, size, make, and the reading at the time of the incident
• The flow and lockup pressures at the outlet side of the meter
• Results of a spot check of the meter. (Complete this when practical and/or safe to do so to ascertain the condition of the customer downstream house lines.)
• Results of an underground bar test sample at the meter riser, and at other locations
• Name of the incident commander or official in charge of the scene
• Any stated cause of the incident as provided by the incident commander or other official
• Results of an odorant level reading using an approved odorometer device.

Note: Never offer verbal comment or speculation as to the suspected cause of a gas related incident. Refer requests for information to your supervisor, Gas Engineering, or the Claims representative, as available. This information shall be recorded on the appropriate Gas Operating Order, and shall also include any other related statements made by fire officials, bystanders, customers, etc. In addition to the arrival and
departure times, the times of any important events should be recorded on the Gas Operating Order, such as the time that pressures were checked, when bar testing was completed, etc.
Note: In cases of a gas related fire, explosion, serious injury, or death, the gas service person shall (in addition to following the procedures as outlined in GESH, Section 4 - Emergency Procedures) extend the limits of the underground leak investigation. Samples shall be taken at four compass points approximately 100 feet past the last indications of any migrating natural gas. If migrating natural gas has not been detected, the limits of the investigation shall also extend out in at least a 100-foot radius from
the structure or incident site, as practical. The intent of this procedure is to firmly establish either the area limits of, or the absence of any natural gas in the vicinity of the incident.
Recording the Scene Gas service person shall take photographs of the incident site, the meter set assembly, and any other items that may help to document or record the scene of the incident. Prior to disconnecting Company equipment, Claims shall be notified. The on-call Claims Department Representative can be reached at 509-495-4357 or 800-727-9170, ext. 4357. Photographs shall be taken both before and after removal of the equipment. Refer to “Chain of Custody” in this section for gas facility chain of custody guidance. Acceptable formats for the photographs are digital. The Service Person should note the date, time and location of each photo. When photos are taken they shall be emailed to the Claims Department at [e-mail] as soon as practical with an explanation including date, address, time, and who took the photos. A detailed map sketch shall be made of the incident site by the service person. The sketch shall indicate compass direction, the structure involved (if any), the location of Company facilities (including mains and services involved), the location of all bar hole samples and the initial percent gas-in-air readings, location of any victims, the location of any barricades or warning tape, and the location of any emergency services (fire and police) vehicles on site. The service person shall attach a separate sheet of paper to clearly indicate the above information if it will not fit on the Gas Operating Order. Removal of Company Equipment
Removal of the gas meter or other facilities may be required due to damage or due to a specific request by emergency services. Removal of any equipment will only occur with the permission / authorization of fire, police, state or local officials investigating the incident and the permission / authorization of the on-call Avista Claims Representative at 1-509-495-4357 or 1-800-727-9170, ext. 4357. The meter set assembly shall be removed in any of the following cases (bulleted below) after the following condition has been met: CONDITION: Determine from the Claims Department or the Gas Incident Investigator if the IPUC, OPUC, or WUTC will be involved in investigating the incident. If they will be involved, ensure that Avista has permission to remove the meter / facilities from Claims or the Gas Incident Investigator. As applicable, record the name (including time and date) of State Commission person giving permission in the Gas Operating Order.

• In cases where it is apparent that the meter is physically damaged or leaking
• Where the meter serves a structure that has been involved in an explosion
• When removal is specifically requested by a fire or other official, or by a supervisor
• When the meter is in danger of being damaged due to the results of an incident Prior to removing any meters or Company equipment, follow the “Chain of Custody” process. The meter set assembly (including meter, regulator, any overpressure device, fittings, and piping) shall not be removed until the inspection and pressure check has been completed and the results recorded on the Gas Operating Order, and a photograph has been taken. The meter set assembly should be removed in the presence of a fire official or investigator. The meter set assembly shall be kept together as a single unit, separate from any other meter set equipment. Gas meters, meter set components, and other gas facilities are the property of Avista Utilities and shall be initially retained by Company personnel, then tagged for identification and transported to Company facilities for safekeeping. It is preferable that a representative from the Claims Department transport any evidence, if practical. If Claims is unavailable to transport the facilities, the employee removing or transporting the facilities shall contact the Claims Department to determine the location of the appropriate secured facility for storage. After the meter set assembly has been removed, the service person shall check the distribution delivery pressure at the riser and record this information on the Gas Operating Order. The service valve shall be locked off and an idle riser marker with warning sticker shall be installed (Refer to GESH, Section 9 - Meter Change Order/Meter Removal Order). The service person shall exercise care during removal to ensure that none of the parts of the meter set assembly become damaged further and to ensure that none of the settings are changed or affected. Tagging and Transporting Meters Meters and regulators that have been removed due to an incident shall be tagged with the following information:
• Date and time of removal
• Location and/or address where meter was installed
• Name of employee that removed the meter or meter set assembly
• Final destination per Claims (where meter is to be retained) The removed meter set assembly shall be transported as a unit, in an upright position, to the appropriate secured Company storage facility (lockup). It is recommended that the meter set be wrapped in plastic or placed in a box for transport, especially if the weather is inclement. The meter set shall be secured in the transport vehicle to avoid movement or loss. The gas service person shall indicate on the Gas Operating Order and/or any evidence tag where the meter, meter set components, or other evidence was during transport (including times). It is preferable that the Claims Department transport any evidence, if practical. Upon delivery to the appropriate secure Company storage facility, the gas service person shall indicate on the Gas Operating Order which employee received the meter set in question and the date and time of delivery.

Inspection and Testing of Meters The appropriate gas meter shop shall obtain the meter set assembly or components for inspection and testing only after authorization has been obtained from the lead investigative authority or the Claims Department. Meter shop personnel shall check for the following items:
• Flow and lockup pressures of the pressure regulator
• Proper registration of the meter index
• Accuracy of the meter in relation to established tariffs
• Obvious signs of damage (cracks, broken index, evidence of meter being hit, etc.)
• Leakage (as detected by submersion test or soap test as applicable)
• Determination of the cause of any abnormalities
The Claims Department shall be notified prior to commencement of any authorized testing of the meter
set or components so that the appropriate representatives may be present at the testing site. The On-Call Claims Department Representative can be reached at 509-495-4357 or 800-727-9170, ext. 4552.
Testing Warning All initial component testing that is part of the investigation process shall be performed at the actual operating conditions found at the time of the incident, not at 1-1/2 times the MAOP. Higher test pressures may cause new damage that obscures the true cause of the incident. This is different than a re-instatement of service test. To re-instate service, the procedures outlined in the Gas Standards Manual, Specification 3.18, Pressure Testing shall be followed.
After testing and analysis is complete, the Claims Department shall retain custody of the meter set or
other evidence in the secure lockup until it has been determined that the evidence is no longer needed.
Non-Gas Related Incidents
Incidents that are responded to, but may not be gas related may include:
• Fire department calls to close a gas meter for safety reasons
• Fire department calls to remove a gas meter for safety reasons In any of these cases it is important that the following procedures be followed:
• Ask the Incident Commander or other official if natural gas was involved or not or if gas is suspected to be involved in the incident. (Record the name of the Incident Commander and the
date, time, and details of the conversation.)
• Obtain a meter spot check on the house piping, if practical.
• Record the flow and lockup pressures found at the outlet side of the meter if practical.
• Obtain an underground sample at the meter riser and at several other points around the structure
and the service line, if possible.
• If asked to remove the meter, note on the Gas Operating Order (form N-2633) who requested the removal, the reason for the removal, and the date and time the meter was removed.
