The withdrawal of surface water from the South Fork Rivanna River Reservoir, not to exceed a maximum daily withdrawal volume of 48.0 million gallons. Authorization of this withdrawal shall also be subject to the conditions in Part I.F below. 9. Surface water impacts resulting from the compensation site creation or restoration activities shall be authorized under this permit, provided that no in -stream work occurs in tributaries within the Buck Mountain Creek compensation site from May 15th through July 31St of any year. The exception for coffer dam installation in Part I.C.8 shall apply. The permittee shall include a detailed summary of the temporary and permanent impacts, including but not limited to the type and amount of impacts, and shall provide proposed compensation for the permanent impacts in the final compensation plan. Any impacts to state waters resulting from the proposed compensation site construction activities shall be compensated for and approved by DEQ prior to construction. B. Permit Term This permit is valid for 15 years from the date of issuance. If the permittee desires to continue the water withdrawal activities authorized by this permit after it expires, a new application must be submitted to DEQ at least 180 days prior to the expiration of this permit. The application will be evaluated by DEQ based on the regulations and laws in effect at that time. C. Conditions Applicable to All Project Construction and Compensatory Mitigation Activities 1. The activities authorized by this permit shall be executed in such a manner that any impacts to stream beneficial uses are minimized. As defined in § 62.1-10(b) of the Code, "beneficial use" means both instream and offstream uses. Instream beneficial uses include, but are not limited to, the protection of fish and wildlife habitat, maintenance of waste assimilation, recreation, navigation, and cultural and aesthetic values. Offstream beneficial uses include, but are not limited to, domestic (including public water supply), agricultural, electric power generation, commercial, and industrial uses. Public water supply uses for human consumption shall be considered the highest priority. 2. No activity shall substantially disrupt the movement of aquatic life indigenous to the water body, including those species that normally migrate through the area, unless the primary purpose of the activity is to impound water. 3. At crossings of streams, pipes and culverts less than 24 inches in diameter shall be countersunk a minimum of three inches, and pipes and culverts greater than 24 inches in diameter shall be countersunk a minimum of six inches to provide for the re- establishment of a natural stream bottom and to maintain a low flow channel. For multiple -celled culverts, only the bottoms of those cells situated below the limits of VWP Individual Permit No. 06-1574, Major Modification No. 1 Part I - Special Conditions Page 3 of 35 ordinary high water shall be countersunk. To the greatest extent practicable, other cells, pipes, or culverts shall be elevated to provide a natural distribution of flood flows. The requirement to countersink shall not apply to extensions or maintenance of existing culverts that are not countersunk, to floodplain culverts being placed above ordinary high water, to culverts being placed on bedrock, or to culverts required to be placed on slopes 5% or greater. 4. Flows downstream of the project area shall be maintained to protect all beneficial uses as specified in this permit. 5. Excepting the construction of the dam, no activity shall cause more than minimal adverse effect on navigation, and no activity shall block more than half of the width of a stream or water body at any given time. 6. The activity shall not impede the passage of normal or expected high flows, and any associated structure shall withstand expected high flows. 7. Temporary in -stream construction features such as cofferdams shall be made of non - erodible materials. 8. No in -stream work shall occur from May 15tb through July 31St of any year on any perennial or intermittent stream being disturbed for installation or relocation of utility lines, including water transport pipelines. This restriction does not apply to utility line crossings installed via directional drilling where the stream bottom is not disturbed. An exception will be made for the installation of cofferdams, which may occur during these restricted time periods, provided that all practicable procedures are followed to prevent or reduce the likelihood of events that would cause the coffer dam to lose isolation from free flowing channels. Instream work does not include work that is performed behind a cofferdam or in a secured area isolated from a free flowing channel. This restriction may be lifted if further mussel surveys performed on perennial or intermittent stream crossings (except those being directionally drilled), or further consultation with the Virginia Department of Game and Inland Fisheries and United States Fish and Wildlife Service, concludes that suitable mussel habitat is not present. Once exact pipeline crossings of perennial streams are determined, the permittee shall consult with the Department of Game and Inland Fisheries on the need to perform mussel surveys on perennial tributaries to Ivy Creek. Surveys for freshwater mussels requested by the Department of Game and Inland Fisheries shall be conducted 100 meters upstream through 400 meters downstream of impact areas. Surveys should be performed by a qualified biologist, preferably no more than six months prior to the start of construction. All mussels encountered within the impact area should be relocated upstream into VWP Individual Permit No. 06-1574, Major Modification No. 1 Part I - Special Conditions Page 4 of 35 suitable habitat and any listed species should be tagged for future monitoring. Relocation should occur within 30 days of the start of construction to avoid or minimize the chance that mussels will recolonize the work area. 9. Surveys for Indiana bats shall be re -conducted if tree -clearing activities in forested areas do not occur within three years of July 26, 2011. Any surveys conducted as a result of this permit condition shall be performed by a qualified biologist in accordance with standard survey protocols acceptable to the Virginia Department of Game and Inland Fisheries (DGIF) and the United States Fish and Wildlife Service (USFWS). If surveys are necessary, the permittee shall submit a survey plan to DEQ at least 45 days prior to commencing tree -clearing activities, and no tree -clearing activities shall commence until DEQ receives written concurrence from DGIF and USFWS that the activities are not likely to adversely affect this species. 10. All excavation, dredging, or filling in surface waters shall be accomplished in a manner that minimizes bottom disturbance and turbidity. Turbidity levels downstream of any in - stream construction sites shall be minimized to the greatest extent practicable at all times. 11. Erosion and sedimentation controls shall be designed in accordance with the Virginia Erosion and Sediment Control Handbook, Third Edition, 1992, or the most recent version in effect at the time of construction. These controls shall be placed prior to clearing and grading activities and shall be maintained in good working order, to minimize impacts to surface waters. These controls shall remain in place only until clearing and grading activities cease and these areas have been stabilized. 12. All construction, construction access, and demolition activities associated with this project shall be accomplished in a manner that minimizes construction materials or waste materials from entering surface waters. Wet, excess, or waste concrete shall be prohibited from entering surface waters. Measures shall be employed at all times to prevent and contain spills of fuels, lubricants, or other pollutants into surface waters. Any fish kills, or spills of fuels or oils, shall be reported to DEQ immediately upon discovery at (540) 574-7800. If DEQ cannot be reached, the spill shall be reported to the Virginia Department of Emergency Management (DEM) at 1-800-468-8892 or the National Response Center (NRC) at 1-800-424-8802. DEQ shall be notified in writing within 24 hours or as soon as possible on the next business day when potential environmentally threatening conditions are encountered which require debris removal or involve potentially toxic substances. Measures to remove the debris or potentially toxic substance, or to change the location of any structure, are prohibited until approved by DEQ, except to the extent that emergency measures are required to protect against imminent threats to public health and safety. In such instances DEQ shall be notified within 24 hours of taking the emergency action. Virginia Water Quality Standards shall not be violated in any surface waters as a result of the project activities. VWP Individual Permit No. 06-1574, Major Modification No. 1 Part I - Special Conditions Page 5 of 35 13. All authorized fill material placed in surface waters shall be clean and free of contaminants in toxic concentrations or amounts in accordance with all applicable laws and regulations. 14. All non -impacted wetlands, streams, open water, and designated upland buffers that are located within fifty feet of any project activities shall be clearly marked or flagged for the life of the construction activity within that area. The permittee shall notify all contractors and subcontractors that no activities are to occur in these marked areas. 15. Machinery or heavy equipment used in temporarily impacted wetlands shall be placed on mats or geotextile fabric, or other suitable means shall be implemented, to minimize soil disturbance to the maximum extent practical. Mats, fabrics, or other measures shall be removed as soon as the work is complete in the temporarily impacted wetland. 16. Temporary disturbances to wetlands, stream channels, and/or stream banks during project construction activities shall be avoided and minimized to the maximum extent practicable_ 17. All materials (including fill, construction debris, excavated materials, and woody materials) that are temporarily placed in wetlands, in stream channels, or on stream banks shall be placed on mats or geotextile fabric, and shall be immediately stabilized to prevent the materials, or leachate associated with the materials, from entering surface waters. The materials shall be entirely removed within 30 calendar days following completion of that construction activity. After removal, disturbed areas shall be restored to pre-existing conditions (except for mature woody vegetation) in accordance with Part I.H. 18. All required notifications and submittals shall be submitted to the DEQ office stated below, to the attention of the VWP permit manager, unless directed in writing by DEQ subsequent to the issuance of this permit: Virginia Dept. of Environmental Quality Office of Wetlands and Water Protection P. O. Box 1105 Richmond, Virginia 23218 19. All reports required by this permit and other information requested by DEQ shall be signed by the permittee or a person acting in the permittee's behalf, with the authority to bind the permittee. A person is a duly authorized representative only if both criteria below are met. If a representative authorization is no longer valid because of a change in VWP Individual Permit No. 06-1574, Major Modification No. 1 Part I - Special Conditions Page 6 of 35 responsibility for the overall operation of the facility, a new authorization shall be immediately submitted to DEQ. a. The authorization is made in writing by the permittee. b. The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated facility or activity, such as the position of plant manager, superintendent, or position of equivalent responsibility. A duly authorized representative may thus be either a named individual or any individual occupying a named position. 20. All submittals shall contain the following signed certification statement: "I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations." 21. The permittee shall notify the DEQ of any additional impacts to surface waters, including wetlands, and of any change to the type of surface water impacts associated with this project. The permittee shall also notify the DEQ of any substantial or material modifications to the design or configuration of the dam, culverts, in -stream armoring, concrete support piles and piers, intake structure, raw water intake tower, raw water pumping station, existing dam removals, or raw water pipeline installation. Any additional impacts, modifications, or changes affecting surface waters shall be subject to individual permit review and/or modification of this permit. Compensation may be required. 22. The permittee shall provide the public with access to Ragged Mountain Reservoir. D. Stream Modifications, Including Intake/Outfall Structures 1. Any exposed slopes or stream banks shall be stabilized immediately upon completion of work in each impact area. Methods and materials for stabilization shall be in accordance with the Virginia Erosion and Sediment Control Handbook, Third Edition, 1992, or the most recent version in effect at the time of construction. 2. Redistribution of existing stream substrate for erosion control purposes is prohibited, unless otherwise authorized for compensatory mitigation purposes. VWP Individual Permit No. 06-1574, Major Modification No. 1 Part I - Special Conditions Page 7 of 35 3. Material removed from the stream bottom shall not be deposited into surface waters unless otherwise authorized as fill material in this permit. 4. Outlet protection for all outfalls and piped channel sections shall be designed in accordance with Virginia Erosion and Sediment Control Handbook, Third Edition, 1992, or the most recent version in effect at the time of construction. Alternative energy dissipation measures may be installed with prior approval by DEQ. 5. For stream bank protection activities, structures and backfill shall be placed as close to the stream bank as practical, while still avoiding and minimizing impacts to vegetated wetlands to the maximum extent practical. No material shall be placed in excess of the minimum necessary for erosion protection. 6. Asphalt and materials containing asphalt or other toxic substances shall not be used in the construction of submerged sills, breakwaters, dams, or weirs. 7. If stream channelization or relocation is required, all work in surface waters shall be done in the dry, unless authorized by this permit, and all flows shall be diverted around the channelization or relocation area until the new channel is stabilized. The diversion shall be accomplished by leaving a plug at the inlet and outlet ends of the new channel during excavation. Once the new channel has been stabilized, flow shall be routed into the new channel by first removing the downstream plug and then the upstream plug. The new stream channel shall be constructed following the typical sections submitted with the final design plans and should incorporate natural stream channel design principles to the greatest extent practicable. A low flow channel shall be constructed within the channelized or relocated area. The centerline of the channel shall meander, to the extent possible, to mimic natural stream morphology. The rerouted stream flow shall be fully established before construction activities in the old streambed can begin. E. Utilities All utility line work in surface waters shall be performed in a manner that minimizes disturbance in each area. Temporarily disturbed surface waters shall be restored in accordance with the applicable conditions of Part I.H.1 and I.H.2, unless otherwise authorized by this permit. 2. Material resulting from trench excavation may be temporarily sidecast into wetlands not to exceed a total of 90 calendar days, provided the material is not placed in a manner such that it is dispersed by currents or other forces. VWP Individual Permit No. 06-1574, Major Modification No. 1 Part I - Special Conditions Page 8 of 35 3. The trench for a utility line cannot be constructed in a manner that drains wetlands (e.g., backfilling with extensive gravel layers creating a French drain effect). F. Water Withdrawal and Instream Flow Conditions 1. Definitions: "Natural inflow," when used with respect to South Fork Rivanna Reservoir, is the daily mean discharge rate listed by the United States Geological Survey for the Mechums River near White Hall, Virginia (USGS stream gage 02031000), multiplied by the factor of 2.71 (to compensate for the difference in drainage area), and converted from cubic feet per second to millions of gallons per day by multiplying by a factor of 0.65. Currently, the USGS mean discharge rates are available online at httu://waterdata.usgs.g_ov. "Natural inflow," when used with respect to Sugar Hollow Reservoir, is the daily mean discharge rate listed by the United States Geological Survey for the Mechums River near White Hall, Virginia (USGS stream gage 02031000), multiplied by the factor of 0.19 (to compensate for the difference in drainage area), and converted from cubic feet per second to millions of gallons per day by multiplying by a factor of 0.65. Currently, the USGS mean discharge rates are available online at htty://waterdata.us sg gov. "Initial fill," with respect to an Expanded Ragged Mountain Reservoir, refers to the period of time beginning when the facility becomes operational (as defined below), and ending when either (a) the water level at the facility for the first time reaches the normal pool elevation, or (b) a permanent operation and maintenance certificate is issued for the facility by the Virginia Department of Conservation and Recreation, whichever is later. "Operational," with respect to a new water supply facility, means that it has been completely constructed, can be operated as intended, and is in active service. With respect to an Expanded Ragged Mountain Reservoir, the facility shall be deemed "operational" upon issuance of a temporary operation and maintenance certificate by the Virginia Department of Conservation and Recreation, even though the Reservoir may not fill with water to its full normal pool elevation until some time thereafter. "Total downstream flow" is the rate at which all water in a stream is moving past a defined point and flowing downstream during a given interval of time. Total downstream flow is expressed in millions of gallons per day and includes, but is not limited to, all water traveling over a dam spillway, water seeping through, around, or under a dam or spillway, water conveyed through a pipeline from a reservoir to the downstream, or water conveyed through a hydroelectric plant from a reservoir to the downstream during the defined interval. VWP Individual Permit No. 06-1574, Major Modification No. Part I - Special Conditions Page 9 of 35 "Urban Water System" is the system of water supply reservoirs, intakes, pipelines, and water treatment facilities that provide potable drinking water to the citizens of the City of Charlottesville and areas of the County of Albemarle surrounding the City as defined by the Board of Supervisors. Water storage for the Urban Water System includes the Sugar Hollow Reservoir, the Ragged Mountain Reservoir, and South Fork Rivanna Reservoir. "Useable storage" is the volume of water in a reservoir at a particular time that is available for routine withdrawal and use for water supply purposes. It consists of all that volume of water within a reservoir located above the dead storage pool (or sediment pool) up to the water surface elevation. The volume of useable storage at a particular reservoir at a given time depends upon the water surface elevation (which shall be determined by observation), and upon the then -current contour of the reservoir bottom and elevation of the dead storage pool (which shall be determined from the most recent stage -storage curves prepared by the Rivanna Water & Sewer Authority under the seal of a professional engineer on the basis of periodic bathymetric surveys). "Total useable storage" is the sum of the Useable Storage in each of the storage reservoirs in the Urban Water System at a given time. 2. Where provisions applicable to a fully -Expanded Ragged Mountain Reservoir (Total Useable Storage of 2.189 billion gallons, normal pool elevation of 683 feet) differ from those applicable to an intermediate -Expanded Ragged Mountain Reservoir (Total Useable Storage of 1.549 billion gallons, normal pool elevation of 671 feet), the provisions shown in brackets shall apply to an intermediate -Expanded Ragged Mountain Reservoir. 3. Total downstream flow Provisions before an Expanded Ragged Mountain Reservoir is Operational. a. From South Fork Rivanna Reservoir: i. When the water level at South Fork Rivanna Reservoir is at or above the spillway elevation of 382 feet, South Fork Rivanna Reservoir will be spilling water on a daily basis and no additional total downstream flow is required. ii.
