The Plan projects the future water needs of the City through the proposed planning period of 45 years (year 2050). The plan includes an evaluation of the existing water source, treatment capacity, storage capacity, and distribution capacity, as well as existing usage. This addresses the requirements of VAC25-780-70, 80, and 90. No conclusions have been drawn at this time. The City intends to complete the plan in stages as funding allows and only the first phases of the plan have been addressed at this time. Conclusions and recommendations will be included in the future in the final plan. The Virginia Department of Environmental Quality has provided funding and technical assistance during the completion of this report. Bristol Virginia Utilities Water Supply Plan City of Bristol, Virginia Page 4 of 16 I. Purpose and Scope The City of Bristol, Virginia, acting through its water utility, Bristol Virginia Utilities (BVU), has developed this water supply plan in accordance with Title 9 VAC25-780. The Plan includes existing data from other water plans for the City and projects the future water needs of the City through the proposed planning period of 45 years (year 2050). The Local and Regional Water Supply Planning Regulation establishes a planning process and criteria that all local governments will use in the development of local or regional plans. These plans will be reviewed by the Virginia Department of Environmental Quality and a determination will be made by the State Water Control Board whether the plans comply with this regulation. The plans will be reviewed every five years to assess adequacy and significant changes will require the submission of an amended plan and review by the Board. This regulation was developed to implement the mandate of Senate Bill 1221 (2003, c.227, SB1221), which requires that “The Board, with the advice and guidance from the Commissioner of Health, local governments, public service authorities, and other interested parties, shall establish a comprehensive water supply planning process for the development of local, regional and state water supply plans consistent with the provisions of this chapter.” The purpose of this regulation is to protect the health, safety and welfare of citizens by requiring local and regional water supply planning. The goal of this regulation is to establish a basic set of criteria that each local or regional water supply plan must contain so that they may plan for and provide adequate water to their citizens in a manner that balances the need for environmental protection and future growth. The City of Bristol Water Supply Plan includes an evaluation of the existing water source, treatment capacity, storage capacity, and distribution capacity, as well as existing usage. Future demand projections were calculated with input from various sources. An expansion plan will not be developed. BVU has retained Mattern & Craig to prepare the water supply plan on behalf of the City of Bristol. II. General Information This plan includes information for the citizens of the City of Bristol, Virginia as supplied with water by BVU. The general project information is as follows: Political Subdivision Included Bristol, Virginia Contact Person Wes Rosenbalm, President Address 15022 Lee Highway Bristol, Virginia 24202 Bristol Virginia Utilities Water Supply Plan City of Bristol, Virginia Page 5 of 16 Phone (276) 645-8701 Fax (276) 645-2020 Email Address [email protected] Information for this report was gathered in conjunction with the BVU water system staff and water treatment plant staff. Historical information was gathered from VDH, DEQ, and BVU records. Environmental data was gathered from the United States Geological Survey, Tennessee Valley Authority, and historical records. III. Planning Area and Service Area This plan is intended to include the City of Bristol, Virginia. There are two Cities of Bristol, one each located in Tennessee and Virginia, operating as separate governments. The Cities are separated by State Street. Bronze plates are installed on the center line of the Street approximately identifying the TN-VA State line. Bristol, Virginia is located within Washington County, Virginia, although the City operates as a separate government from the County. The project planning area is identical to the water service area, which is the bounds of the City Limits in 2006. A map of this boundary is shown below. An increase in the service area would have to include annexations by the City into Washington County, Virginia. There have been recent discussions of such annexations but, for the purpose Bristol Virginia Utilities Water Supply Plan City of Bristol, Virginia Page 6 of 16 of this plan, it will be assumed that the Bristol City Limits remain constant throughout the planning period. Changes in the City Boundary would affect both the City Plan and the Washington County Plan. If the Washington County Plan addresses all areas outside the city limits, then all areas in and around the City of Bristol should be covered by a plan. It should be noted that the BVU water treatment plant supplies water in a bulk purchase arrangement to the Washington County Service Authority. This water would be the supply for the southwestern end of Washington County, adjacent to the Bristol Planning and Service Area. This service area should also be accounted for in the Washington County water supply plan. IV. Evaluation of Existing Water Supply A. Existing Water Source Information 9VAC 25-780-70 This section includes information on the existing water sources, including reservoirs and interconnections, in accordance with regulation 9VAC 25-780-70. Section A The City of Bristol utilizes one primary water source and operates a water treatment plant (WTP) located in Washington County, Virginia. The WTP uses an intake on South Holston Lake, which is provided water from the Middle Fork and South Fork Holston River. The water plant is located approximately 10 miles from the City limits of Bristol. While South Holston Lake itself is only 6 miles from the City limits, the intake and water treatment plant are located much further upstream. The BVU water treatment plant was built in 1954 with a 5 MGD capacity and is located at the intersection of State Route 677 (Watauga Road) and State Route 902 approximately 3 miles southeast of the Town of Abingdon. The WTP was expanded in 1978 to 10 MGD and is currently producing approximately 3.5 Million Gallons of water each day. The Water Treatment plant is a conventional water treatment plant utilizing high rate filtration at 4
