BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION
ERIC CONRAD
COMPLAINANT,
CASE NO. INT-G.16.01
COMMENTS OF THE
COMMISSION STAFF
vs.
INTERMOUNTAIN GAS COMPANY,
RESPONDENT.
The Staff of the Idaho Public Utilities Commission, by and through its Attorney of
Record, Donald L. Howell II, Deputy Attorney General, submits the following comments in this
case.
BACKGROUND
On December 27,2015, Eric Conrad filed a formal complaint against Intermountain Gas
Company. While building a home near Idaho Falls, Intermountain Gas required Mr. Conrad to
install a meter protection structure at his own expense before the utility would install the gas
meter and riser, thereby providing gas service to his new residence.
STAFF COMMENTS MARCH 7 ,2016
To rectify the meter protection issue, Mr. Conrad initially built a free-standing wooden
structure that covered the meter when installed. According to Mr. Conrad, Intermountain Gas
allegedly determined that the wooden structure was inadequate because it was not permanently
affixed to the residence and was not approved by an engineer to accommodate heavy snow load
for the area. Mr. Conrad subsequently contacted Intermountain Gas for additional information
regarding protection structures. However, Mr. Conrad claims that the materials provided by
Intermountain Gas did not have any technical specifications pertaining to what constituted an
adequate structure for protecting the gas meter.
Mr. Conrad also alleged that he observed a number of homes that have been built in 2015
that did not appear to have meter protection structures in place. After Mr. Conrad contacted the
Staff for assistance, Intermountain provided him with photographic examples of constructed and
prefabricated meter protection structures.
In his formal complaint, Mr. Conrad requested that the Commission order Intermountain
Gas to compensate him for his cost and labor in installing the protection structure ($370) and
$1,010.82 in construction loan interest caused by the delay in timely installing his meter.
STAFF REVIEW
Staff shares Intermountain Gas Company's (IGC or Company) concerns about customer
and employee safety and protection of gas meters in situations that pose a safety risk. Staff
recognizes that snow or ice falling from a roof poses such a risk, and that in some circumstances,
it is necessary to protect a customer's meter and piping from potential damage. Staff maintains
that to adequately ensure the safety of customers and the Company's employees, IGC must: (1)
establish specific criteria for meter placement and technical specifications for meter protection;
(2) make the criteria publicly available, especially with respect to the construction industry; and
(3) apply the criteria consistently across the Company's service territory.
Criteria and Technical Specifications
Staff maintains that Intermountain Gas' Answer did not adequately demonstrate that it
has established any specific criteria regarding meter placement or meter protection. IGC's
Procedures Manual provides some general guidance, but it lacks specific criteria that can be used
to objectively determine if additional meter protection is needed. The manual also lacks
technical specifications for meter protection structures. The Company states that precise meter
STAFF COMMENTS MARCH 7 ,2016
protection specifications do not and cannot exist at the level of detail that Mr. Conrad had
requested. See Answer at p. 7. However, Staff believes that criteria and technical specifications
do exist. Staff Attachments 1,2 and 3 provide examples from Puget Sound Energy, Wisconsin
Public Service, and Enbridge Gas Distribution. This information is publicly available through
the utilities' respective websites and describes each company's requirements and technical
specifications for placing and protecting meters in areas with snow-load. For example, Puget
Sound Energy's information at pages I and 3 of Attachment 1 provide technical specifications,
including diagrams for protecting meters utilizing the pre-existing structure of the home and
building meter protection structures for the various meters installed by Puget Sound Energy.
Reliance on References to Various Codes
In its Answer, IGC relies heavily on the Intemational Fuel Gas Code and CFR Title 49
Part 192 as guidelines for the proper placement and protection for gas meters. Staff maintains
that neither of the codes referenced by the Company provide any substantive information
pertaining to the technical specifications for protecting a meter from weather-related events. For
example, 49 CFR Section 192.353(a) simply provides that "Each meter and service regulator,
whether inside or outside a building, must be installed in a readily accessible location and be
protected from corrosion and other damage, including, if installed outside a building, vehicular
damage that may be anticipated." Likewise, Section 401.1 of the International Fuel Gas Code
provides "Pressure regulators shall be protected from physical damage." See Answer, Exhibit 4
p.l. Furtherrnore, the Company's Answer states: "Builders and owners who don't often build in
areas of snow should take the necessary steps to identiS the unique building standards for these
areas." See Answer at p. 4-5. Staff is not aware of any state or local building code that
specifically addresses the construction of additional meter protection on homes in areas with
heavy snow load.
Information Available to Customers. Contractors. Builders and Others
Staff maintains that the information provided by the Company to customers, contractors,
builders, and other members of the construction industry is inadequate. According to the
Company's response, customers are provided personalized communication pointing out potential
environmentalhazards. See Answer atp.4. Mr. Conrad was provided an outdated generic form
letter that was not personalized, did not address any potential hazards specific to his property,
STAFF COMMENTS MARCH 7 ,2016
and did not provide technical specifications regarding acceptable meter protection devices. See
Complaint at p.30.
The Company also claims to regularly contact builders that consistently build in high
snow areas. Staff finds this practice inadequate because it does not account for builders that may
have lower construction volume, as in the case of Mr. Conrad's builder, JBK Construction, or do
not consistently build structures requiring natural gas. Staff recommends that at least once each
year, IGC advise builders and contractors within its service territory of its criteria. For example,
Idaho Power uses local builder associations as a resource to compile a list of builders and
contractors within its service territory, which it uses to distribute a brochure regarding the
technical requirements associated with Idaho Power's Reduced Charge Option for installing the
conduit for underground electrical service. See Attachment 4.
Whereas the CFR Title 49 Part 192 and the International Fuel Gas Code generally require
protection of meters and piping from known hazards and are publicly available resources, IGC's
Procedures Manual is an in-house document not currently made available to the general public.
Staff identified several utilities, including Duke Energy, Pacific Gas and Electric, Madison Gas
and Electric Co., Puget Sound Energy and Baltimore Gas and Electric that publish service
requirements and guidelines on their websites in PDF format for the general public. Staff
recommends that after the Company establishes its criteria and technical specifications, that such
information should be made available to customers, contractors, builders and others on its
website. In addition, printed information, e.g., brochures, flyers, booklets, etc., should be
available for distribution to customers and others upon request.
IGC Procedures Manual and Employee Trainine
l. Manual Language: Staff finds the language in the IGC Procedures Manual to be in
direct contradiction to the Company's Answer to the complaint. The manual states that "IGC
will provide protection for the meter sets when required." Yet the Company states in its answer
that a note on the Customers Service Line Work Order said "[Customer] advised may need meter
protection. Already piped out." See Answer, Exhibit 5. That note implies meter protection may
not be needed. However, at some later time the Company determined that meter protection was
required and it must be provided by Mr. Conrad as a condition of receiving service. IGC
maintains that the language in its manual regarding IGC providing meter protection should not
be taken literally to mean IGC will provide such protection. See Answer at p. 7. Staff
STAFF COMMENTS MARCH 7 ,2016
recommends that the manual be revised to clarify the conditions under which meter protection
will be provided by the Company without charge.
2. Training: In its Answer, the Company states that employees of IGC are trained to
recognize that when a natural gas meter is located in the "Drip-line of a non-gabled end of a roof,
the meter is unprotected and unsafe." See p.6. Staff was unable to find any language in the
Company's Procedures Manual that specifies the "drip-line" as the determinant factor for
requiring additional meter protection. In addition, the manual seems to indicate that gutters may
offer meter protection. See Answer, Exhibit 3,p.2. However, when Mr. Conrad told IGC
personnel that he intended to have gutters installed, he was told that gutters do not suffice as
adequate meter protection.
It appears to Staff that employee training is not consistent with IGC's Procedures
Manual. This inconsistency could lead to employee confusion and contribute to a lack of
consistent application of the Company's safety requirements. Staff recommends that the
Company reconcile any inconsistencies between its Procedures Manual and employee training.
Staff also recommends that steps be taken to ensure consistent application of its meter protection
criteria across the Company's service territory.
STAFF RECOMMENDATION
(l) Staff recommends the Company establish specific criteria for determining the
need for additional meter protection and technical specifications for meter protection structures.
(2) Staff recommends that after the Company establishes its specific criteria and
technical specifications, that information be made available to customers, contractors, builders
and others on its website. In addition, printed information, e.g., brochures, flyers, booklets, etc.,
should be available for distribution to customers and others upon request.
(3) Staff recommends that at least once each year, IGC advise builders and
contractors within its service territory of its criteria and technical specifications for meter
protection.
(4) Staff recommends that the Company's Procedures Manual be revised to clarify
the conditions under which meter protection will be provided by the Company without charge.
(5) Staff recommends the Company reconcile any inconsistencies between its
Procedures Manual and the training provided to employees.
STAFF COMMENTS MARCH 7 ,2016
(6) Staff recommends that steps be taken to ensure consistent application of its
criteria across the Company's service territory.
(7) Staff recommends that the Company be directed to work with Staff in complying
with the Commission's order.

The best solution is to avoid installing the gas meter and piping where vehicles could accidentally run into the gas meter and
piping. ltistheresponsibilityofthecustomertoprovideasafelocationfornewgasmetersandregulators. lfthisisnot
possible, meter protection is usually needed. The customer, the building inspector, or the Company can determine if meter set
protection is needed. Without it, vehicular traffic could accidentally collide with the gas facilities causing a potentially
dangerous situation which could result in serious injury or damage. Protection usually consists of one or more 4" or larger
steel posts. A 6" concrete curb can also be used. The customer can install either post or 6" curb. The Company will install
posts for a fee. This usually consists of one or more posts or protectors.
Please call the Company for assistance if you have or think you may have a potentially dangerous meter location.
1. The drawings above are typical post layouts for areas where protection is needed.
2. When installing the posts, use good judgment in areas such as alleys, driveways, walkways, etc.
3. The post should be buried to a depth of 30" and should extend 36" above the ground. Tamped granular material
shall be used around post or use approximately one foot of concrete or Speed-Crete, and fill the balance of the hole
with tamped granular material. Posts shall not be driven. Always call Diggers' Hotline al 1-800-242-8511 prior to
making any excavations.
4. Posts should be level and plumb with other posts. Fill the post with sand or gravel and cap off with concrete.

The Meter Box is designed to integrate the gas regulator, meter, and shut-off valve into the
architectural detail of multi-dwelling units. The design contains two components: the Meter
Box and the NPS 2 Grey PVC conduit.
The PVC conduit is installed in the foundation at the time of forming. The Meter Box is then
framed in on top of the foundation wall and secured in place. This allows for the gas service
and meter to be installed at a later time by Enbridge Gas Distribution.
Upon final installation, a gas-tight seal of the interior of the box must be ensured so any
potential migration of gas may be vented through the screen opening at the front of the box.
The Builder is responsible for supplying the Meter Box and the PVC conduit as part of
this installation.
Above: Meter Box lnstallation Example. The Meter Box is desiSned to integrate the gas
regulator, meter, and shut-off valve into the architectural detail of the building.

Prior to the gas service installation, the Builder has the responsibility of ensuring the Meter
Box and PVC conduit have been installed according to these specifications.
lnstallation of NPS 2 Grey PVG Conduit
The PVC conduit must conform to the following guidelines to ensure clear access to the gas
meter, regulator, and shut-off valve.
lncorrect installations of the conduit, which compromise the integrity of Enbridge Gas
Distribution's gas meter set, will be repaired by the Builder.
1) The piping used as the conduit for these installations is standard NPS 2 grey PVC pipe;
compatible fittings must also be used.
2) The PVC condult must be completely encased in concrete, with a minimum of 50 mm (2 in)
of concrete encasement around the circumference of the piping.
3) Alljoints must be glued and taped before installation in the concrete to ensure continuity
of the PVC conduit.
4) The PVC conduit must extend 50 mm (2 in) into the box through the precut hole provided
in the bottom of the box. The top of the PVC conduit must be cut evenly; a damaged or
fractured conduit will not be accepted.
5) The PVC conduit must be installed as illustrated in the drawings provided in the Appendix.
Additional horizontal or vertical offsets of the conduit are not acceptable.
6) The Builder must ensure the integrity of the PVC conduit during the construction process
and seal both ends to prevent contamination prior to the installation of the gas service.

Deviations from Standard lnstallations - PVG Gonduit
If the Meter Box can not be located on the foundation, for example as result of a poured
concrete porch or steps, the conduit may extend a maximum of 300 mm (12 in) above
top of the foundation without additional concrete. encasement.
For installations with more than 300 mm (12 in) elevation above the foundation, approval
from Enbridge Gas Distribution is required.,, Th'es€,.;,initattations may require the PVC :'
conduit to be completely encased in concrete from the top of the foundation to the
bottom of the Meter Box.
Common lnstallation Pitfalls - PVG Gonduit
Above: Two examples of common pitfalls and unacceptable installations of the PVC conduit.
Left: The PVC conduit extends more than 300 mm (12 in) above the base of the foundation. This
type of installation requires additional consideration and approval by Enbridge Gas Distribution
prior to the start of construction (i.e. when submittingl a preliminary request for site servicing).
Right: This installation is unacceptable because the PVC conduit is not completely encased with
a 50 mm (2 in) encirclement of concrete. Remedial action would be required prior to service
installation.

lnstallation of Meter Box
Proper installation of the PVC conduit in the foundation allows the Meter Box to be installed
according to these guidelines and ensures an acceptable meter configuration for Enbridge
Gas Distribution. lnstallations that do not conform to these guidelines must be corrected
prior to the service installation.
The Meter Box is designed with precut holes, which align the PVC conduit with the gas
reSulator, meter, and supply line connection. Modifications to the precut openings in the box
are not permitted. Exceptions are to be reviewed and approved by Enbridge Gas Distribution
prior to the installation of the gas service.
1) The Meter Box must be secured prior to the service installation to prevent movement of
the box or PVC conduit. The Meter Box does not adequately support masonry. The Builder
shall use lintel angles above the box in order to support masonry.
2) The location of the Meter Box must allow for 0.9 m (3 ft) clearance of building openings
and 1.0 m (40 in) clearance from sources of ignition (measurements to be taken from
edge of the screen on the front of the box to the building opening).
3) The Meter Box shall be installed such that the bottom of the box is on the foundation.
lf the Meter Box can not be located on the foundation, for example as result of a poured
concrete porch or steps, the Meter Box may be elevated a maximum of 300 mm (12 in)
above the foundation. For installations with more than 300 mm (L2 in) separation,
approval from Enbridge Gas Distribution is required (please also see "Deviations from
Standard lnstallations - PVC Conduit" on page 8).
4) The Meter Box door must be accessible at all times and must be able to open freely.
Clearance of 600 mm (24 in) in front of the door must be maintained to allow for access
to Meter Box. Modifications to the door of the Meter Box are not permitted; the door shall
not be fixed in place by any means.
5) The meter must be left in such a condition that the front portion of the box can be
installed as designed.

It is the responsibility of the Builder to ensure that the Meter Box is gas tight and that any
potential migration of gas will vent throuSh the screen opening in the door of the Meter Box.
This includes sealing the PVC conduit entrance into the bottom of the box, the Meter Box
edges and corners, and the supply line exit at the top of the box.
Materials used to seal the Meter Box must ensure the long-term integrity of a gas-tight
installation. The preferred sealant for the conduit entrance and supply line exit is a sealing
slug. The preferred sealant for the box edges and corners is silicone exteriorgrade caulking.
Duct sealer caulking and spray foam insulation are also suitable sealants provided a gas-tight
seal is ensured.
Fitter, fu rn On .ahd,:liiipection
During the final inspection (EBl), it is necessary to comply with these standards for Meter Box
installations. Failure to meet these standards may result in delays in activatin$ $as services.
Failed inspections of Meter Box installations will not be activated until corrective action has
been taken. Damages to the meter set as a result of supply line tie-ins will be repaired at
the Builder's cost. For example, any damages caused by connections to the meter outlet for
winter construction heat will be repaired at the Builder's expense.
Fina! Grade Re{ui1eme4.ts
At time of service installation, final grade shall be within 150 mm (6 in) of construction grade.
Please note that damages can occur after the installation of the gas service as a result of
