These water bodies were listed as impaired on Virginia's 303(d) Total Maximum Daily Load Priority List and Reports (DEQ, 1998, 2002, 2004, 2006) because of violations of the state's water quality standards for E. coli and for fecal coliform bacteria. Description of the Study Area The bacteria impaired Rivanna River watershed is located within the borders of Albemarle, Greene, Nelson, and Orange counties. The city of Charlottesville is also within the watershed's boundaries. All impaired streams are located in the Rivanna River watershed (USGS Cataloging Unit 02080204). The entire Rivanna River bacteria impaired watershed is approximately 321,877 acres. Impairment Description Segments of the Rivanna River mainstem, North Fork Rivanna River, Preddy Creek and tributaries, Meadow Creek, Mechums River, and Beaver Creek were listed as bacteria impaired on Virginia's 2002, 2004, and/or 2006 303(d) Total Maximum Daily Load Priority List and Reports due to violations of the state's water quality standard for fecal coliform bacteria and/or E. coh. The impaired segments are located in the Rivanna River Basin in central Virginia. The watershed is located in the hydrologic unit (HUC) 02080204. The impaired watersheds include the City of Charlottesville and portions of Albemarle, Greene, Orange, and Nelson counties. The impaired segment of the Rivanna River (VAV-H28R-RVNOIA00) extends 5.28 miles along the mainstem from the confluence of the North Fork Rivanna River to Moores Creek. This segment of the Rivanna River was first listed on the 2006 305(b)/303(d) Water Quality Assessment Integrated Report for exceedances of the E. coli standard. During the 2006 assessment period (January 200 through December 2004), 2 Executive Summary E-1 out of 9 samples (22%) collected at listing station 2-RVN037.54 exceeded the E. coli criterion of 235 cfu/100 ml The impaired segment of Beaver Creek (VAV-H23R-BVR02AO4) extends 4.8 miles from its headwaters to Beaver Creek Reservoir.

During the 2004 assessment period (January 1998 through December 2002), 2 out of 16 fecal coliform samples (13%) collected at listing station 2-BVR005.70 exceeded the fecal coliform standard instantaneous of 400 cfu/100 ml. This segment remained on the 303(d) list in the 2006 Water Quality Assessment Report. The impaired segment of Meadow Creek (VAV-H28R-MWCOIA00) extends 4.01 miles from its headwaters to the confluence of the Rivanna River. This segment of Meadow Creek was first listed on the 2002 303(d) Water Quality Assessment Integrated Report for exceedances of the fecal coliform standard. During the 2002 assessment period (January 1996 through December 2000), 4 out of 23 fecal coliform samples (17%) collected at listing station 2-MWC000.60 exceeded the fecal coliform instantaneous standard of 400 cfu/100 ml. The impaired segment of the Mechums River (VAV-H23R-MCMOIA00) extends 10.44 miles from the confluence of the Lickinghole Creek to the Moormans River. This segment of the Mechums River was first listed on the 2006 305(b)/303(d) Water Quality Assessment Integrated Report for exceedances of the E. coli standard. During the 2006 assessment period (January 2000 through December 2004), 2 out of 18 samples (11%) collected at listing station 2-MCM005.12 exceeded the E. coli criterion of 235 cfu/100 MI. The impaired segment of the North Fork Rivanna River (VAV-H27R-RRNOIA00) extends 10.38 miles from the public water intake to the confluence of the Rivanna River. This segment of the North Fork Rivanna River was first listed on the 2006 305(b)/303(d) Water Quality Assessment Integrated Report for exceedances of the E. coli standard. During the 2006 assessment period (January 2000 through December 2004), 3 out of 9 Executive Summary E-2 samples (33%) collected at listing station 2-RRN002.19 exceeded the E. coli criterion of 235 cfu/100 ml. The impaired segment of Preddy Creek and its tributaries (VAV-H27R-PRDOlA00) extends 25.96 miles from its headwaters to the confluence of the Rivanna River. This segment of Preddy Creek was first listed on the 2006 305(b)/303(d) Water Quality Assessment Integrated Report for exceedances of the E. coli standard. During the 2006 assessment period (January 2000 through December 2004), 3 out of the 9 samples (33%) collected at listing station 2-PRD000.21 exceeded the E. coli criterion of 235 cfu/100 ml. During this same period, only 1 out of the 9 samples (11%) collected at listing station 2- PRD004.42 exceeded the E. coli criterion of 235 cf i/100 ml. Applicable Water Quality Standards At the time of the initial listing of Rivanna River mainstem, North Fork Rivanna River, Preddy Creek and tributaries, Meadow Creek, Mechums River, and Beaver Creek segments, the Virginia Bacteria Water Quality Standard was expressed in fecal coliform bacteria; however, the bacteria water quality standard has recently been changed, and is now expressed in E. coli. Virginia's bacteria water quality standard currently states that E. coli bacteria shall not exceed a geometric mean of 126 E. coli counts per 100 mL of water for two or more samples within a calendar month, or an E. coli concentration of 235 counts per 100 mL of water at any time. However, the loading rates for watershed - based modeling are available only in terms of the previous standard, fecal coliform bacteria. Therefore, the TMDL was expressed in E. coli by converting modeled daily fecal coliform concentrations to daily E. coli concentrations using an in -stream translator. This TMDL was required to meet both the geometric mean and instantaneous E. coli water quality standard. Watershed Characterization The land use characterization for the Rivanna River watershed was based on a combination of land cover data from the National Land Use Land cover data set (NLCD) using 2001 reference data and the Virginia Department of Forestry 2005 land use data. Executive Summary E-3 Dominant land uses in the watershed are forest (64%) and agriculture (21%). These account for a combined 85% of the total land area in the watershed The potential sources of fecal coliform include run-off from livestock grazing, manure applications, industrial processes, residential, and domestic pets waste. Some of these sources are driven by dry weather and others are driven by wet weather. The potential sources of fecal coliform in the watershed were identified and characterized. These sources include permitted point sources, failed septic systems and straight pipes, livestock, wildlife, and pets. TMDL Technical Approach The Hydrologic Simulation Program -Fortran (HSPF) model was selected and used as a tool to predict the in -stream water quality conditions of the delineated watershed under varying scenarios of rainfall and fecal coliform loading. HSPF is a hydrologic, watershed -based water quality model. The results from the model were used to develop the TMDL allocations based on the existing fecal coliform load. Basically, this means that HSPF can explicitly account for the specific watershed conditions, the seasonal variations in rainfall and climate conditions, and activities and uses related to fecal coliform loading. The modeling process in HSPF starts with the following steps • delineating the watershed into smaller subwatersheds • entering the physical data that describe each subwatershed and stream segment • entering values for the rates and constants that describe the sources and the activities related to the fecal coliform loading in the watershed The Rivanna River watershed was delineated into 41 smaller subwatersheds to represent the watershed characteristics and to improve the accuracy of the HSPF model. Of these 41 representing the entire Rivanna River watershed, 28 were within the bacteria impaired watershed. This delineation was based on topographic characteristics, and was created using a Digital Elevation Model (DEM), stream reaches obtained from the National Hydrography Dataset (NHD), and stream flow and in -stream water quality data. Executive Summary E-4 Stream flow data were available from the U.S. Geological Survey (USGS). Weather data were obtained from the National Climatic Data Center (NCDC). The data used in the model include meteorological data (hourly precipitation) and surface airways data (including wind speed/direction, ceiling height, dry bulb temperature, dew point temperature, and solar radiation). The period of January 1998 to December 2006 was used for HSPF hydraulic calibration and validation. The hydrologic calibration parameters were adjusted until there was a good agreement between the observed and simulated stream flow, thereby indicating that the model parameterization is representative of the hydrologic characteristics of the study areas. The model results closely matched the observed flows during low flow conditions, base flow recession and storm peaks. Instream water quality data for the calibration was retrieved from DEQ, and was evaluated for potential use in the set-up, calibration, and validation of the water quality model. The existing fecal coliform loading was calculated based on current watershed conditions. Since Virginia has recently changed its bacteria standard from fecal coliform to E. coli the modeled fecal coliform concentrations were changed to E. coli concentrations using a translator. TMDL Calculations The TMDL represents the maximum amount of a pollutant that the stream can receive without exceeding the water quality standard. The load allocation for the selected scenarios was calculated using the following equation: Where, TMDL = 2] WLA +2] LA + MOS WLA = wasteload allocation (point source contributions); LA = load allocation (non -point source allocation); and MOS = margin of safety. Executive Summary E-5 The margin of safety (MOS) is a required component of the TMDL to account for any lack of knowledge concerning the relationship between effluent limitations and water quality. The MOS was implicitly incorporated in this TMDL. Implicitly incorporating the MOS required that allocation scenarios be designed to meet a 30-day geometric mean E. coli standard of 126 cfu/100 mL and the instantaneous E. coli standard of 235 cfu/100 mL with 0% exceedance. Typically, there are several potential allocation strategies that would achieve the TMDL endpoint and water quality standards. A number of load allocation scenarios were developed to determine the final TMDL load allocation scenario. For the hydrologic period of January 2000 to December 2006, fecal coliform loading and instream fecal coliform concentrations were estimated for the various scenarios using the developed HSPF model of the Rivanna River mainstem, North Fork Rivanna River, Preddy Creek and tributaries, Meadow Creek, Mechums River, and Beaver Creek. After using the instream translator, the TMDL allocation plan was developed to meet geometric mean and instantaneous E. coli standards. Based on the load -allocation scenario analyses, the daily TMDL allocation plans that will meet the 30-day E. coli geometric mean water quality standard of 126 cfu/100 mL and the instantaneous E. coli water quality standard of 235 cfu/100 mL are presented in Table E-1.

The benefits of staged implementation are: 1) as stream monitoring continues to occur, it allows for water quality improvements to be recorded as they are being achieved; 2) it provides a measure of quality control, given the uncertainties that exist in any model; 3) it provides a mechanism for developing public support; 4) it helps to ensure the most cost effective practices are implemented initially, and 5) it allows for the evaluation of the TMDL's adequacy in achieving the water quality standard. Table E-4 provides load reduction targets for staged implementation achieving a 10% instantaneous standard violation reduction for each TMDL watershed. While section 303(d) of the Clean Water Act and current EPA regulations do not require the development of TMDL implementation plans as part of the TMDL process, they do require reasonable assurance that the load and wasteload allocations can and will be implemented. Additionally, Virginia's 1997 Water Quality Monitoring Information and Restoration Act (the "Act") directs the State Water Control Board to "develop and implement a plan to achieve fully supporting status for impaired waters" (Section 62. 1 - Executive Summary E-8 44.19.7). The Act also establishes that the implementation plan shall include the date of expected achievement of water quality objectives, measurable goals, corrective actions necessary and the associated costs, benefits and environmental impacts of addressing the impairments. EPA outlines the minimum elements of an approvable implementation plan in its 1999 "Guidance for Water Quality -Based Decisions: The TMDL Process." The listed elements include implementation actions/management measures, timelines, legal or regulatory controls, time required to attain water quality standards, monitoring plans, and milestones for attaining water quality standards. Once developed, DEQ intends to incorporate the TMDL implementation plan into the appropriate Water Quality Management Plan (WQMP), in accordance with the Clean Water Act's Section 303(e). In response to a Memorandum of Understanding (MOU) between EPA and DEQ, DEQ also submitted a draft Continuous Planning Process to EPA in which DEQ commits to regularly updating the WQMPs. Thus, the WQMPs will be, among other things, the repository for all TMDLs and TMDL implementation plans developed within a river basin.
