UTILITY ADVISORY COMMITTEE MEMO DATE: April 13, 2004 TO: UTILITY ADVISORY COMMITTEE FROM: Bill Beverford, Superintendent, Water/Wastewater Collection Division SUBJECT: Leak Detection Results - 2004 Summary: The City has utilized leak detection companies for the past fourteen years to detect water leaks in the distribution system. During the past five years, these surveys have recovered 183,600 gallons per day, or 67,014,000 gallons per year of water loss. Detecting and repairing these leaks results in the utility becoming more efficient in the areas of water conservation and recovery of lost water revenue. This year's leak detection survey was performed from March 15th through March 19th. The estimated combined water loss that was detected and repaired was found to be 7,920 GPD. iRecommendation: Information Only. Background/Analysis: Each year the Water/Wastewater Collection Division contracts with a leak detection company to perform a survey of one-fifth of the water distribution system. Utilities Services Group conducted the survey this year. Extremely sensitive sound amplification instruments and computer based correlations are used for pinpointing these leak locations. City crews spend about ten days preparing for the contractor's equipment by locating and uncovering the necessary contact points in the system. The general area covered was south of Lauddson Blvd., High School and College areas of the distribution system. This year a total of approximately 25.04 miles were surveyed including all intersecting lines. Approximately 40 hours were spent on this project and a total of three leaks were found within our distribution system. Additionally, two leaks on the customer side were found and notification was passed on to them. The water loss due to leakage was estimated to be, excluding the customer side leaks, approximately 7,920 GPD, which would equal 2,890,800 gallon per year. All of the detected leaks have been repaired. Attach: Summary of survey and Pinpointing Report.

WASHINGTON, U.S.A. UTILITY ADVISORY COMMITTEE MEMO DATE: April 13, 2004 TO: UTILITY ADVISORY COMMITTEE FROM: BILL Beverford, Superintendent, WaterFvVastcwater Collection Division SUnJECT: WATER QUALITY REPORT (2003) Summary: The Washington State Department of Health requires that every water system provide an annual Water Quality Report to its customers. The report is to contain information on the potential contaminants present in the water supply that customers receive. The attached Water Quality Report for the Port Angeles Water Supply has been prepared for distribution to the City's water customers. Recommendation: For Information Only. Background/Analysis: In 1996 Congress passed amendments to the Safe Drinking Water Act that included a mandate for the Environmental Protection Agency (EPA) to require cormnunity water systems to provide each of their customers with a "Consumer Confidence Report, (CCR)" every twelve months. This year's report, using 2003 data, will be delivered to all City of Port Angeles water customers with the May utility billing statements, along with a public information announcement in the local paper, and posted on the City's web site. This year's report must be distributed by July 1, 2004. The attached Water Quality Report for calendar year 2003 has been developed in accordance with the EPA/CCR regulations. The regulations require information on the quality of the water delivered by the system, and characterization of any risks from exposure to contaminants in the drinking water, in an accurate and understandable manner. The City was also required to provide information to its wholesale customer, the Clallam County Public Utility District, by April 1st. Attachment: Water Quality Report - 2003 City of Port Angeles Water Quality Report - 2003 Dear Water Customer: The City of Port Angeles is pleased to provide this annual Water Quality Report. Its purpose is to tell you about the high quality of the City's water and water system. This report is a summary of the quality of water provided in 2003. It is a record reflecting the hard work by City employees to bring you water that satisfies all of the requirements of the national Safe Drinking Water Act. Is my water safe? Last year, as in years past, your tap water met all U.S. Environmental Protection Agency (EPA) and state drinking water health standards. The City of Port Angeles vigilantly safeguards its water supply and once again we are proud to report that our system has provided you, the customer, with safe, reliable, and high quality ch'inking water. This report includes details about where your water comes from, its quality and how it compares to stringent standards set by regulatory agencies. We believe that customers who are well informed are able to make better decisions about their drinking water supply. Do I need to take special precautions? Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791). Where does my water come from? The source for the City of Port Angeles Water System is a Ranney Collector (well) located on the east bank of the Elwha River near river mile 2.8, in Section 3} T 30 N, R 7 W. The system identification number is 68550M. The Ratmey Collector has been classified as groundwater under the influence (GWI) of surface water. This designation requires the City to meet requirements of the Surface Water Treatment Rule (SWTR). Regulatory compliance options available under the SWTR include filtration and complying with criteria to avoid filtration. The City and the Washington State Department of Health have negotiated an agreement that will effectively meet the filtration avoidance requirements by the construction of a federally-funded municipal water treatment facility under the Elwha River Ecosystem and Fisheries Restoration Act. In the agreement, the water treatment facility will be in place before dam removal begins. This is referenced in the Bilateral Compliance Agreement, (BCA), Docket # 00-02-014. Source water assessment and its availability: Water from the Rarmey Collector is tested following the guidelines established by the Washington State Department of Health (DOH) to detect potential contaminants that could reasonably be expected to be found in drinking water. Because most of the land through which the Elwha River flows is inside the Olympic National Park, there is limited opportunity for human contamination of the water. Contaminants that might be expected in untreated water include; biological contaminants, such as viruses and bacteria, inorganic contaminants, such as salts and metals, pesticides, and herbicides, organic chemicals, from industrial or petroleum use, and radioactive materials. Why are these contaminants in my drinking water? Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA's Safe Drinking Water Hotline (800-426-4791). This information can also be accessed at the EPA's website, www.epa.gov/safewater/ccrl.html. The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or human activity. Microbial contaminants, such as viruses and bacteria, may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Inorganic contaminants, such as salts and metals, can be naturally occurring or result from urban stormwater runoff, industrial, or domestic wastewater discharges, oil and gas production, mining, or fanning. Pesticides and herbicides, may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by- products of industrial processes and petroleum production, can also come from gas stations, urban stormwater runoff, and septic systems. Radioactive contaminants, can be naturally occurring or be the result of oil and gas production and mining activities. In order to ensure that tap water is safe to drink, EPA prescribes regulations that limit the amount of certain contaminants in water provided by water systems. Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled water and must provide the same protection for public health. For some constituents, DOH prescribes lower maximum contaminant levels than EPA does. How can I get involved? Water Conservation Tips Water conservation measures are an important first step in protecting our water supply. Such measures not only save the supply of our water, but can also cut the cost of water treatment. Here are a few suggestions. CONSERVATION MEASURES YOU CAN USE INSIDE YOUR HOME: 1 .) Fix leaking faucets, pipes, toilets, etc. 2.) Install water saving devices in faucets, toilets, and appliances. 3.) Replace old fixtures with new ones. This will reduce water consumption by nearly one-half. 4.) Wash only full loads of laundry. 5.) Do not use the toilet for a trash disposal. 6.) Take shorter showers. Do not let the water nm while shaving, washing, brushing teeth, or cleaning fruits or vegetables. 7.) Soak dishes before washing. Run the dishwasher only when full. YOU CAN CONSERVE OUTDOORS AS WELL: 1 .) Water the lawn and garden in the early morning or evening. 2.) Use mulch around plants and shrubs. 3.) Repair leaks in faucets and hoses. Use water-saving nozzles. 4.) Use water from a bucket to wash your vehicle. Save the hose for rinsing. FOR MORE INFORMATION: The City of Port Angeles Council meets at 6:00p.m. on the 1st and 3rd Tuesday of each month at City Hall, 321 E. 5tn Street.

Variance and Exemptions In 2003 the City of Port Angeles requested and was approved to reduce monitoring of Disinfection/Disinfectants by Products by the DOH. Having met the sampling requirements agreed to and those sampling results to be below the Maximum Contaminant Levels (MCL's) of Trihalomethanes, Halo-Acetic Acids (HAA(5)'s) and Total Organic Carbon (TOC's). The City's water system operates under two Bilateral Compliance Agreements (BCA's) with the DOH: Docket # 7207 - Covering of Uncovered Finished Water Supply Reservoirs and Installation of Corrosion Control, (All five reservoirs are now covered and will proceed with required sample testing to determine if Corrosion Control measures will be necessary), Docket # 00-02-014 - Groundwater Under the Influence of surface Water. Details for both of the BCA's are available upon request from the City of Port Angeles Water Superintendent at (360) 417-4855 or by email at bbeverford~cityofpa.us. 3 Term Definition ug/L ug/L: Number of m/crograms of substance in one liter of water mg/L mg/L: Number nf milligrams of substance in one liter of water ppm ppm: parts per mill/on, or milligrams per liter (mg/L) ppb ppb: parts per billion, or micrograms per liter 0tg/L) ppt ppt: parts per trill/on, or nanograms per liter ppq ppq: parts per quadrillion, or picograms per liter pC//L pCi/L: picocuries per liter (a measure of radioactivity) mrem/yr mrem/yr: millirems per year (a measure of radiation absorbed by the body) MFL MFL: million fibers per liter, used to measure asbestos concentration NTU NTU: NephelomeUSc Turbidity Units.

UTILITY ADVISORY COMMITTEE MEMO DATE: April 13, 2004 TO: UTILITY ADVISORY COMMITTEE FROM: Stephen Sperr, P.E., Engineering Manager SUBJECT: Acquisition of Rayonier tank and property Summary: There is an opportunity to purchase the 5.3 million gallon tank still in ptace on Rayonier property near the mouth of Ennis Creek and using it for combined sewer flow storage without having to move it. This could save the City a significant amount of money if the use of the tank is feasible. Recommendation: That City staff investigate the viability of purchasing the 5.3 million tank and land on which it sits from Rayonier. Background/Analysis: At the February 10, 2004 UAC meeting, Brown and Caldwcll (the City's wastewater consultant) made a presentation on the alternatives available to reduce Combined Sewer Overflows (CSO) in thc next 11 years. One element of these alternatives is the choice of whether to (1) treat all the wet weather flows beyond the capacity of the existing Wastewater Treatment Plant (WWTP) with a new treatment system near the WWTP, or (2) use the existing 5.3 million gallon above ground steel tank that Rayonier has left on their property near the WWTP to store excess flows and meter it back into the WWTP for treatment later. On the next page is a map from Brown and Caldwell's presentation, and shows the location of the tank. At that time, it was understood that the Rayonier tank would have to be moved to a site closer to the WWTP in order to use it, so that its current location could be part of the overall redevelopment of the Rayonier mill site. Recent discussions with City staff and officials from Rayonier have indicated that the tank could remain at its current location if the City chooses to use it for storage to reduce the volume and frequency of CSO events. It is for this reason that we have brought this issue back to the UAC for discussion on whether to continue to pursue this option. Rayonier has indicated to City staffthat they would like to know by April 30 if the City has a real interest in acquiring the tank and the surrounding property, and/or other part(s) of its property there for locating a new treatment plant. At this time, Rayonier has placed a value of roughly $2.50 per square foot for all its property at the former mill site, regardless of its future potential for development. This comes to about $250,000 for property on which to place a new treatment system, or about $1 million for land if the existing tank site is purchased. But the savings from not having to move the tank would be about $3 million. April 13, 2004 UAC Meeting Rayonier Tank Page 2 of 2 It is recommended that the Utility Advisory Committee encourage City staff to continue to pursue the possibility of acquiring the 5.3 mg Rayonier tank and a suitable amount of property on which it sits by taking the following steps: 1. Direct Brown and Caldwell to complete a phYSical inspection of tank and its piping, using industry standard testing methods. 2. Discuss the possible purchase of the tank and acquisition of Rayonier property with the Real Estate Committee. 3. If the tank is structurally viable for use as a storage tank, complete a "due diligence" investigation of the tank site to confirm the ability to use it as intended. 4. Bring this issue back to the UAC before any action is recommended to City Council. AxcIMS Viewer Page 1 of 1 htro ://www.clallam.net/aimsxwebsit e/CA_pUblic_htmlcust/MapFrame.htm 04/12/2004
