Home My WebLink About2003 NS Manager - Re-authorization of County Participation in the Triangle Area Water Supply Monitoring ProjectSTATE OF NORTH CAROLINA COUNTY OF CHATHAM COUNTY OF DURHAM COUNTY OF ORANGE COUNTY OF WAKE 4 AMENDMENT TO INTERLOCAL AGREEMENT THIS AGREEMENT is made and entered into by and between the County of Chatham, the County of Orange, the County of Wake, the Town of Apex, the Town of Cary, the City of Durham, the Town of Hillsborough, the Town of Morrisville and the Orange Water and Sewer Authority, to be effective from and after July 1, 2003. WITNESSETH: WHEREAS, on August 18, 1988, several local governments in Region J, including the County of Chatham, the County of Orange, the Town of Apex, the Town of Carrboro, the Town of Cary, the Town of Chapel Hill, the City of Durham, and the Town of Hillsborough, entered into an interlocal agreement to establish the Triangle Area Water Supply Water Quality Monitoring Project (the "Monitoring Project ") applicable to certain surface water supplies in Region J; and WHEEREAS, the County of Wake and the Town of Morrisville have agreed to enter into the same interlocal agreement to continue the Monitoring Project; and WHEREAS, the Orange Water and Sewer Authority has agreed to enter into the same interlocal agreement on behalf of the Town of Chapel Hill and the Town of Carrboro to continue the Monitoring Project; and WHEREAS, the Monitoring Project was initially established for a three -year period, and said interlocal agreement was subsequently amended to extend the Monitoring Project for Phase II through June 30, 1991, for Phase III through June 30, 1999, and for Phase IV through June 30, 2003; and WHEREAS, water quality monitoring activities during Phases I through IV have been funded through local contributions and a major cost share match through a Joint Funding Agreement with the U.S. Geological Survey; and WHEREAS, the primary objectives of the Monitoring Project are to: (a) supplement existing data on major ions, nutrients, and trace elements to enable determination of long -term water quality trends; (b) examine the differences in water quality among water supplies within the region, especially differences among smaller upland sources, large multi - purpose reservoirs, and run -of -river supplies; (c) provide tributary loading data and in -lake data for predictive modeling; (d) establish a database for the presence or absence of synthetic organic compounds in surface waters in the region; and (e) report results of the monitoring program to governmental officials, the scientific community, and the general public; and Page 1 of 14 TRIANGLE AREA WATER SUPPLY WATER QUALITY MONITORING PROJECT 5 AMENDMENT TO INTERLOCAL AGREEMENT WHEREAS, the Monitoring Project will complete its Phase IV monitoring program on June 30, 2003; and WHEREAS, the local governments participating in the project established a Monitoring Project Steering Committee to make technical, financial, and administrative recommendations to the participating local entities; and WHEREAS, said Committee has determined that additional monitoring is needed and desirable to meet the objectives of measuring water quality conditions and long -term trends in water quality. NOW, THEREFORE, the undersigned units of local government have agreed: 1. That the term of the Interlocal Agreement dated August 8, 1988 and amended July 1, 1991, July 1, 1995, and July 1, 1999, under which they have operated the Monitoring Project for certain water supplies in Region J, shall be and is hereby extended until the completion of the project or June 30, 2007, whichever is earlier, and that the terms and conditions thereof, and the duties and obligations of the parties thereunder, shall be and remain as set out in the Interlocal Agreement as amended July 1, 1999, except as hereby specifically modified. 2. That the activities of the Monitoring Project continue to be guided by the goals and objectives summarized above. 3. That the monitoring program continue as summarized in Attachment A, "Summary of TAWSMP Work Program for Phase V: FY 2004 — FY 2007." 4. That the annual funding support provided by local participants for Fiscal Years 2004 through 2007 shall be as shown on Attachment B to this Amendment, or as otherwise necessary to undertake the project as recommended by the Project Steering Committee, provided, however, the funding level does not exceed the local participants' projected share of annual costs for FY 2004 -7. Page 2 of 14 TRIANGLE AREA WATER SUPPLY WATER QUALITY MONITORING PROJECT 6 AMENDMENT TO INTERLOCAL AGREEMENT ATTACHMENT A SUMMARY OF TAWSMP WORK PROGRAM FOR PHASE V: FY 2004 — FY 2007 Since it began in 1988, the Triangle Area Water Supply Monitoring Project has made significant progress towards the goals and objectives originally established for the project. Through the project, participating local governments have worked together to establish a stronger base of information upon which to determine long -term changes in water quality. The project has also increased our understanding about the presence or absence of synthetic organic chemicals in the Triangle Region's drinking water supply sources. This data is important to local and state agencies responsible for the provision and protection of drinking water supplies. The Triangle Area Water Supply Monitoring Project Steering Committee, which is composed of representatives from each participating local government, recommends that this cooperative monitoring project continue. The Steering Committee recommends the following: 1. that water quality monitoring be continued at the sites and frequencies, and for the parameters listed on Table 1 of the Triangle Area Water Supply Monitoring Project Proposal for Phase V (see Attachment C); 2. that stream flow gaging be continued at the sites also shown on Table 1 (see Attachment C); 3. that data collection at existing tributary sites be increased during high -flow event; and 4. that the presence of emerging water - quality contaminants such as pharmaceutical compounds and antibiotics be determined at 7 sites near water - supply intakes as shown on Table 1 (see Attachment C). 5. that a report be published that includes analysis of water - quality trends for data collected through 2005. During Phase V, the Steering Committee will work with the U.S. Geological Survey to increase public awareness and understanding of the Project and the quality of water-supply sources in the region through periodic progress reports, press releases, presentations, and by maintaining a Project web site. Page 12 of 14 TRIANGLE AREA WATER SUPPLY WATER QUALITY MONITORING PROJECT AMENDMENT TO INTERLOCAL AGREEMENT ATTACHMENT B TAWSMP ANNUAL COST SHARES FOR PHASE V: FY 2004 — FY 2007 The annual cost for Phase V of the Triangle Area Water Supply Monitoring Project is $340,000. The US Geological Survey will provide a fifty percent cost share match of $170,000. The Monitoring Project Partners' total annual cost for Phase V is the remaining $170,000, plus $12,000 for TJCOG services and support. The Monitoring Project Partners' individual annual cost shares are the sum of a base rate and a variable rate. The base rate is thirty percent of the total annual Monitoring Project Partners' cost, which is thirty percent of $182,000, divided equally among the Monitoring Project Partners. The variable rate is seventy percent of the total annual Monitoring Project Partners' cost, which is seventy percent of $182,000, multiplied by each Monitoring Project Partners' percentage of the total average annual water use during Calendar Year 2001 for all Monitoring Project Partners.
