WASHINGTON BOISE, IDAHO 83702-5983 Attorney for the Commission Staff BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION IN THE MATTER OF THE APPLICATION OF BAR CIRCLE "8" WATER COMPANY FOR AUTHORITY TO ESTABLISH COMMERCIAL FIRE PROTECTION TARIFF RATES. CASE NO. BCS-O5- COMMENTS OF THE COMMISSION STAFF COMES NOW the Staff of the Idaho Public Utilities Commission, by and through its Attorney of record, Scott Woodbury, Deputy Attorney General, and in response to the May 11 2005 Notice of Application, Notice of Modified Procedure and Notice of Comment/Protest Deadline in Case No. BCS-05-, submits the following comments. BACKGROUND On April 22, 2005, Robert Turnipseed, president of Bar Circle "S" Water Company (Bar Circle; Company) filed an Application with the Idaho Public Utilities Commission (Commission) requesting authority to establish a commercial fire protection tariff. Bar Circle is located in Hayden, Idaho and provides water service to approximately 141 customers. Bar Circle does not currently have an approved commercial fire protection tariff. reflected in its Application, at the request of Water ford Park LLC, a boat and RV condominium storage facility, the Company entered into an agreement with Waterford to provide fire STAFF COMMENTS JULY 8 , 2005 protection service required for the facility. Attached to the Application is a copy of the Waterford agreement and a copy of the engineer s master plan for the storage facility that shows the location of water lines, fire hydrants and sprinkler service lines that are being installed to meet the fire protection requirements. Waterford is paying the cost to mo,;,e existing lines and install new lines and hydrants. Bar Circle states that it must dedicate a large portion of its existing storage reservoir to the fire suppression needs of the Waterford facility. The Company reports that nearly a third of Bar Circle s existing reservoir will be dedicated to meeting the required 53 400-gallon storage requirement. Bar Circle anticipates that additional growth will occur in the area in the near future and that the Company will expand to serve new customers. Because of the large portion of the existing reservoir that will be dedicated to fire protection for the Waterford facility, the Company states that it will need to construct additional storage to meet its growth requirement sooner than anticipated. Attached to the Company s Application is an engineering estimate for the construction of a new 20 000-gallon reservoir. Total cost of the new reservoir is expected to be $90 000. Bar Circle requests approval of commercial fire protection rates as follows: Monthly rate for commercial private hydrants Monthly rate for commercial sprinklers per connection $146. $ 97. The rates were developed using the cost of the new reservoir that could be avoided were it not for the dedication of a portion of the Company s existing facilities. Because the new reservoir much smaller than the dedicated portion of the Company s existing reservoir, the Company believes its calculations are conservative. The fire protection rates when applied to the entire Waterford facility, the Company contends, will generate monthly revenue of$I 121.68. As reflected in attachments to the Company s Application, the dedicated portion of the existing reservoir is the equivalent of 23 residential customers' average daily requirements during the peak season of the year. The fire flow requirement for the Waterford facility, the Company contends, is nearly twice the average demand of the existing residential customers connected to the system. Bar Circle purchased and combined its water system with the Rancho Aero water system in 2002. A Water Master Plan with engineer s report and hydraulic analysis was prepared at that time. The report was favorable with one substantial exception. That exception was the supply STAFF COMMENTS JULY 8 , 2005 a nearby firehouse where pressures could, under some circumstances, be inadequate. Bar Circle resolved the pressure problem by adding a ten (10) inch main. The Bar Circle water system consists of two (2) well pumps (maximum pumping capacity 581 gpm), two (2) storage tanks (one (1) concrete and one (1) steel, total available storage 165 000 gallons), three (3) booster pumps (total maximum capacity 485 gpm), a fire water supply pump (2500 gpm at 150 foot of head), a standby diesel generator capable of running either the booster pumps or the fire water pump at full capacity, and various water mains and distribution lines. The specific connection to Hayden Executive RV and Boat Condos ' (RV Condos) fire protection system is a ten (10) inch main (belonging to Bar Circle) connected to a six (6) inch service (installed and owned by RV Condos). ST AFF REVIEW Staff investigated data available regarding the size and capability of the Bar Circle system to determine whether that system is appropriate for this type of service. The new fire protection system was designed by the Patriot Fire Protection Company of Spokane, Washington (see Attachment No. A). After review of documents and discussions with the fire marshal of the Northern Lakes Fire District, the DEQ in Couer d' Alene and the owner of Bar Circle, it was determined that the water system is well maintained and has the ability to provide this type of service. The current water system is adequate to provide a flow of 640 gallons per minute (gpm) of water at 60 psig for the R V Condos fire protection system and that flow conforms to the National Fire Protection Association (NFP A) requirements. The existing fire protection requirement is that 1 000 gpm of flow be available for residential fire protection. The two fire protection requirements combined (existing residential and new commercial) are 1 640 gpm leaving 442 gpm of the 2 082-gpm total theoretically available for drinking water supply. In parallel, further contacts with the fire marshal in the Northern Lakes Fire District resulted in information that the fire marshal has provided the necessary approvals for the fire protection system. The fire marshal (Dean Marcus) provided two letters stating that both the requirements for the fire protection system are satisfied and that the water system pressure and flow available to meet the fire protection system requirements are adequate, (see Attachment No. A). The DEQ, which has jurisdiction over design and adequacy of the system for supply to and safety of the public, stated that it is investigating this issue and several others and is in discussions with Bar Circle. DEQ stated that it would provide the results of its investigation to STAFF COMMENTS JULY 8, 2005 the PUC when completed. Since the fire protection service is already being provided by Bar Circle, it is appropriate to proceed with a tariff design and rate determination. STAFF'S ANALYSIS OF COMPANY'S PROPOSED RATES The Company in its Application proposed monthly rates of$146.05 per fire hydrant and $97.65 per connection for a commercial sprinkler service. Under these rates the RV Condos would pay a monthly bill of$I 121.68 ($13,460.16 annually). The Company developed these rates using an engineer s estimate for adding a new 500-gallon reservoir to the current system. The Company claims that using this methodology is a conservative approach since the 20 500-gallon reservoir is smaller than the dedicated portion of the Company s existing reservoir needed to provide the fire protection service for Waterford Park. However, the NFP A requirement for storage is 54 300 gallons (see Attachment No. A), which this smaller tank does not satisfy. Staff does not belief the Company s proposal is the appropriate method to determine a tariff rate for the storage facility. The Company is not going to construct the new storage facility. The Company is using an engineer s estimate of the cost to construct the water facility as a surrogate for the cost of the Company s existing storage capacity. The Company is going use its existing storage capacity to provide the capacity required for service. Therefore, the methodology for determining the appropriate tariff should consider only the Company s existing system for servicing the water requirement. Alternatively, the Staff believes that a more appropriate method to determine the rate is to examine the demand that the fire protection service will place on the current system. In this case, the service being provided by Bar Circle to R V Condos does not involve any incremental capital cost and very little additional operating costs. The fire protection system will use very little water on an annual basis. Therefore, Staff believes that an alternative method, based upon the demand the service places upon the current system stated in terms of equivalency to the demand for service by the current customers is more appropriate (see Attachment No. B). TARIFF STRUCTURE AND DETERMINATION METHODOLOGY Since the fire protection system will use little water, but will have significant demand requirements, the fixed monthly rate for fire protection was calculated by Staff based on the fixed monthly cost to meet average demand of an equivalent number of water service customers. STAFF COMMENTS JULY 8, 2005 Further, to check the validity of this method, Staff reviewed similar tariffs at United Water and Eagle Water. The two key requirements for a fire protection system are pumping capacity and water storage. The approved fire protection system requires that 54 300 gallons of storage be available and that 640 gpm of pumping capacity be available. The storage requirement is for a dedicated volume of storage that will always be held ready for the commercial fire protection service. Existing customers may use all of the existing pumping capacity virtually all the time with the commercial fire protection system only using pumping capacity for annual tests or in the event of a fire. Staff, therefore elected to use storage capacity as the surrogate for establishing a tariff. To allocate costs based on storage, fire protection storage demand was established based on average storage demand for an equivalent number of residential water customers. There are 141 Bar Circle customers at present and there are a total of 165 000 gallons of available storage in two different reservoirs. This results in an average storage of 1 170 gallons per customer. The 300 gallons of storage to be dedicated to the fire protection system is equivalent to the average amount of storage for 46.40 customers. The remaining storage of 110 700 gallons provides 785 gallons of storage per customer above the new fire protection storage requirements. While fixed costs of storage are not necessarily recovered in the customer charge, Staff used the current minimum customer charge adjusted for the monthly volume allowance as a proxy for the fixed costs associated with water storage. The Bar Circle minimum charge of$15.00 per month includes 7 500 gallons of water usage. Subtracting the cost of this commodity from the minimum charge at the published tariff of $0.95 per 1 000 gallons, results in a remaining fixed charge of $7.88 per customer per month. The resulting "fixed" storage costs allocated to fire protection is then calculated by multiplying the fixed cost per customer of $7.88 by 46.40 equivalent customers. The resulting tariff is $365.63 per month or $4 384.97 per year. Staff compared rates for similar services in other systems to those derived in this case using the fixed cost methodology. United Water has a tariff for fire hydrants and a separate tariff for sprinkler systems (September 2000). Eagle Water Company has a single tariff sheet for both sprinkler systems and hose connections (July 1982). There are ten (10) service points in the RV Condos fire protection system. They consist of three (3) fire hydrants and seven (7) sprinkler systems, one each in seven different (7) buildings. Applying the RV Condos service points to the United Water tariffs results in a STAFF COMMENTS JULY 8, 2005 monthly tariff of$333.19 and applying the Eagle Water tariff to the RV Condos service results in a tariff of $257.40 per month. Both of these two older tariffs are lower than but are within the same range as those derived by Staff for this case. Staff believes that storing and delivering water for fire protection to a commercial entity is a reasonable service for Bar Circle to offer. Further, pending final comment from the DEQ, Staff believes it likely that Bar Circle will be able to deliver this new service without affecting service to its residential customers. RECOMMENDATIONS Staff recommends that the Commission approve an interim tariff of $365.41 per month for commercial fire protection service. Staff recommends that this tariffbe reviewed once DEQ has made its determination regarding the Bar Circle system s adequacy to handle the addition of the commercial fire protection service. In order to provide consistency between the Bar Circle fire protection tariff and similar existing tariffs, Staff further recommends that that tariff be structured to assess fees for hydrants and for sprinkler systems. The recommended rates are: For each Fire Hydrant For each building sprinkler system $9.50 per month $48.13 per month Respectfully submitted this gi'a day of July 2005. ~~. cott oodbury Deputy Attorney General Technical Staff: Harry Hall Joe Leckie i:umisc:comments/bcsewO5.1swhhjl STAFF COMMENTS JULY 8 , 2005 ATTACHMENT NO.
