SITE WORK WILL INCLUDE CLEARING EXISTING TREES, EARTHWORK, AN ASPHALT PARKING LOT, CONCRETE PADS FOR RECYCLING CONTAINERS AND COMPACTORS, AN ATTENDANCE SHELTER, AND THE INSTALLATION OF UNDERGROUND ELECTRIC CONDUIT. THE PROJECT ALSO PROPOSES A BIORETENTION BASIN TO MEET STORMWATER MANAGEMENT REQUIREMENTS. THE PROJECT WILL HAVE A TOTAL DISTURBED AREA OF APPROXIMATELY 1.75 ACRES. WITHIN THE LIMITS OF DISTURBANCE, THERE ARE 0.01 ACRES CLASSIFIED AS IMPERVIOUS AREA, 0.18 ACRES CLASSIFIED AS MANAGED TURF, AND 1.56 ACRES CLASSIFIED AS FORESTED AREA IN THE EXISTING CONDITIONS. IN THE PROPOSED CONDITIONS, THERE ARE 0.80 ACRES CLASSIFIED AS MANAGED TURF AND 0.95 ACRES CLASSIFIED AS IMPERVIOUS AREA. IN ADDITION, 4.50 ACRES OF FORESTED AREA ON THE PROPERTY OUTSIDE THE LIMITS OF DISTURBANCE WILL BE PLACED IN A PERMANENT EASEMENT FOR PROTECTION. 1.2 EXISTING SITE CONDITIONS THE SITE IS LOCATED IN SOUTHERN ALBEMARLE COUNTY ON ESMONT ROAD. THE PROPERTY IS LOCATED SOUTH OF THE TOWN OF KEENE, WEST OF SCOTTSVILLE ROAD (ROUTE 20), AND EAST OF ESMONT ROAD. IN THE EXISTING CONDITIONS, THE PROPERTY IS MOSTLY FORESTED WITH A GRAVEUDIRT ROAD UNDER THE POWER LINES ACROSS THE FRONT TO THE SITE. A DIRT DRIVE EXTENDS TO THE EAST THROUGH THE MIDDLE OF THE SITE. THERE IS A HIGH POINT THROUGH THE MIDDLE OF THE SITE, FORCING THE RUNOFF FLOW EITHER TO THE NORTH OR SOUTH. THE EXISTING TOPOGRAPHY ON THE WEST END OF THE SITE RANGES FROM 1 % TO 8% WITH SLOPES GRADUALLY BECOMING STEEPER AS YOU MOVE AWAY FROM THE RIDGE RUNNING WEST TO EAST TO APPROXIMATELY 8% TO 16% SLOPES. 11.3ADJACENT PROPERTY THE PROPOSED SITE IS LOCATED IN SOUTHERN ALBEMARLE COUNTY. THE PROPERTIES BOARDING THE SITE ARE ALL CLASSIFIED AS RURAL AREAS. THE PROPERTY TO THE NORTH IS HEAVILY FORESTED WHILE THE PROPERTIES TO THE EAST AND SOUTH ARE A MIX OF FORESTED AND OPEN SPACE. THE SITE IS LOCATED APPROXIMATELY 800 FEET FROM THE INTERSECTION OF ESMONT ROAD AND SCOTTSVILLE ROAD. NO DISTURBANCE WILL TAKE PLACE ON ADJACENT PROPERTY. WITH PROPER SEDIMENT CONTROL IN PLACE TO CONTAIN SEDIMENT BEFORE LEAVING THE LIMITS OF CONSTRUCTION, NO ADVERSE EFFECTS RESULTING FROM SEDIMENT DEPOSITION IS ANTICIPATED FOR ANY OF THE ADJACENT OR DOWNSTREAM AREAS. 1.4 PLANNED OFF SITE ACTIVITIES THE PROJECT IS ANTICIPATED TO REQUIRE THE IMPORT OF FILL MATERIAL. ALL IMPORTED MATERIAL REQUIRED FOR BACKFILL, ETC., SHALL BE OBTAINED FROM A PREVIOUSLY PERMITTED OFF -SITE AREA OR A COMMERCIAL FACILITY. ALL EXCESS OR UNSUITABLE MATERIAL SHALL BE TRANSPORTED TO A PREVIOUSLY PERMITTED OFF -SITE DISPOSAL AREA.

A SMALL PORTION OF THE SOILS ON THE NORTHEAST AND SOUTHWEST SIDES OF THE SITE HAVE SOILS CLASSIFIED AS BUGLEY CHANNERY SILT LOAM WITH A HYDRAULIC SOIL GROUP CLASSIFICATION OF D. REFER TO APPENDIX C-1 FOR THE FULL SOIL REPORT. A FULL GEOTECHNICAL REPORT WAS ALSO COMPLETED FOR THE PROJECT AND WILL BE MADE AVAILABLE FOR THE CONTRACTOR'S USE 1.6 CRITICAL EROSION AREAS THE PROJECT WILL HAVE PROPOSED TIE IN SLOPES OF 3:1 THAT COULD BE CONSIDERED CRITICAL EROSION AREAS. REGULAR INSPECTIONS SHALL BE CONDUCTED ACROSS THE ENTIRE SITE TO ENSURE THE DISTURBED AND DOWNSTREAM SOILS DO NOT BECOME EROSIVE AS CONSTRUCTION PROGRESSES. IN GENERAL, THE CONTRACTOR SHALL MINIMIZE THE AREAS DISTURBED AT ONE TIME AND SHALL IMMEDIATELY APPLY SEED AND MULCH TO DENUDED AREAS AFTER WORK IS PERFORMED. 1.7 EROSION AND SEDIMENT CONTROL MEASURES UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO THE LATEST STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. UNLESS WAIVED OR APPROVED BY LOCAL ADMINISTRATOR, THE MINIMUM STANDARDS OF VESCR SHALL APPLY. 1.8 STRUCTURAL PRACTICES 1. TEMPORARY CONSTRUCTION ENTRANCE - 3.02 A STONE PAD, LOCATED AT THE POINT OF VEHICULAR INGRESS AND EGRESS TO THE CONSTRUCTION SITE. THE PURPOSE IS TO PREVENT OR REDUCE THE AMOUNT OF MUD TRANSPORTED TO THE PUBLIC ROAD. SEDIMENT DISLODGED OR WASHED FROM THE VEHICLE SHOULD BE CONTAINED WITHIN A PROPER SEDIMENT TRAPPING AREA. ALL VEHICLES ENTERING AND EXITING A DISTURBED AREA SHALL USE THE ENTRANCE. THE LOCATION OF THE ENTRANCE MAY NEED TO BE RELOCATED AS CONSTRUCTION PROGRESSES; COORDINATE LOCATIONS WITH INSPECTORS. 2. SILT FENCE - 3.05 SILT FENCE SEDIMENT BARRIERS WILL BE INSTALLED DOWN SLOPE OF DISTURBED AREAS TO FILTER SEDIMENT LADEN RUNOFF. 3. TEMPORARY DIVERSION DIKE - 3.09 TO BE INSTALLED TO DIVERT STORMWATER RUNOFF TO TRAPPING MEASURES BY CREATING A TEMPORARY RIDGE OF COMPACTED SOIL CONSTRUCTED AT THE TOP OR BASE OF A SLOPING DISTURBED AREA. THE LOCATION OF THE DIVERSIONS MAY NEED TO BE ALTERED THROUGHOUT CONSTRUCTION TO ENSURE THE MAXIMUM AMOUNT OF RUNOFF FROM THE DISTURBED AREA IS BEING CAPTURED BY A TRAPPING MEASURE. 4. TEMPORARY SEDIMENT TRAP - 3.13 TO BE USED WHEN THE DRAINAGE AREA IS LESS THAT THREE ACRES TO DETAIN SEDIMENT -LADEN RUNOFF FROM SMALL, DISTURBED AREAS LONG ENOUGH TO ALLOW SEDIMENT TO FILTER OUT OF THE RUNOFF. 4. CHECK DAMS - 3.20 SMALL TEMPORARY STONE DAMS CONSTRUCTED ACROSS DRAINAGE CHANNELS TO REDUCE VELOCITY OF CONCENTRATED FLOWS, AND THEREBY REDUCING EROSION OF THE CHANNEL. 5. SURFACE ROUGHENING - 3.29 APPLIED ON GRADED SLOPES TO AID IN ESTABLISHING VEGETATION, REDUCE RUNOFF VELOCITY AND EROSION, AND PROVIDE FOR SEDIMENT TRAPPING. A ROUGH SOIL IS CREATED BY CREATING HORIZONTAL DEPRESSIONS BY RUNNING A TRACKED PIECE OF EQUIPMENT UP AND DOWN THE SLOPES. 6. TREE PROTECTION - 3.38 A TEMPORARY FENCE INSTALLED AROUND TREES AND VEGETATION THAT WILL REMAIN TO PREVENT DAMAGE DURING CONSTRUCTION. THE FENCING WILL BE INSTALLED ALONG THE DRIP LINE OF THE TREE WHERE POSSIBLE. 7. DUST CONTROL - 3.39 DUST CONTROL MEASURES WILL BE USED OVER THE WHOLE SITE TO REDUCE SURFACE AND AIR MOVEMENT OF DUST DURING LAND DISTURBANCE, DEMOLITION, AND CONSTRUCTION ACTIVITIES. 1.9 VEGETATIVE PRACTICES GENERAL: A PERMANENT VEGETATIVE COVER SHALL BE ESTABLISHED ON DENUDED AREAS NOT OTHERWISE PERMANENTLY STABILIZED BY CONCRETE, PAVEMENT OR LANDSCAPED MULCHED BEDS. PERMANENT VEGETATION SHALL NOT BE CONSIDERED ESTABLISHED UNTIL A GROUND COVER IS ACHIEVED THAT IS UNIFORM, MATURE ENOUGH TO SURVIVE AND WILL INHIBIT EROSION. NEW VEGETATION SHALL BE MAINTAINED FOR ONE FULL YEAR AFTER PLANTING. NEW SEEDING SHALL BE SUPPLIED WITH ADEQUATE MOISTURE, ESPECIALLY LATE IN THE SEASON, AND IN ABNORMALLY HOT OR DRY WEATHER. STABILIZATION PRACTICES SHALL BE ACCOMPLISHED IN ACCORDANCE WITH THE APPROPRIATE VESCH STD. & SPEC. AND AS PER THE EROSION AND SEDIMENT CONTROL PLAN. SELECTION OF THE APPROPRIATE SEED MIXTURE FOR TEMPORARY SEEDING WILL DEPEND UPON THE TIME OF YEAR IT IS APPLIED. 1. TOPSOILING - 3.30 A 4" LAYER OF TOPSOIL SHALL BE APPLIED TO ALL LANDSCAPED AND GRASSED AREAS. THE TOPSOIL SHALL BE FREE OF ROCKS AND DEBRIS. TOPSOIL ALLOWS A STRONGER AND HEALTHIER STAND OF GRASS TO ESTABLISH QUICKLY TO STABILIZE UNPAVED AREAS OF THE SITE. 2. TEMPORARY SEEDING - 3.31 TEMPORARY SEEDING SHALL BE APPLIED OVER DENUDED AREAS THAT WILL NOT BE BROUGHT TO FINAL GRADE WITHIN 14 DAYS. TEMPORARY SEEDING MIXES SHALL BE AS DESCRIBED IN VESCH STD. & SPEC. 3.31. 3. PERMANENT SEEDING - 3.32 PERMANENT SEEDING SHALL BE APPLIED WITHIN 7 DAYS TO ALL AREAS AT FINAL GRADE THAT WILL NOT RECEIVE HARDSCAPE OR OTHER LANDSCAPE. PERMANENT SEEDING SHALL ALSO BE USED ON ALL AREAS THAT ARE NOT AT FINAL GRADE AND THAT WILL BE LEFT DORMANT FOR A PERIOD OF MORE THAN 1 YEAR. IF CONFLICTS EXIST BETWEEN THE PROJECT SPECIFICATIONS AND THE VESCH STD. & SPEC. 3.32, THE MORE STRINGENT REQUIREMENT SHALL APPLY. PERMANENT SEEDING MIXES AND RATES ARE FOUND IN VESCH STD. & SPEC. 3.32. TESTING SHALL BE PERFORMED TO DETERMINE APPROPRIATE AMOUNTS AND LIME AND FERTILIZER TO USE. 4. MULCHING - 3.35 APPLICATION OF PLANT RESIDUES OR OTHER SUITABLE MATERIALS TO THE SOIL SURFACE TO PREVENT EROSION BY PROTECTING THE SOIL SURFACE FROM RAINDROP IMPACT AND REDUCING THE VELOCITY OF OVERLAND FLOW. IT IS ALSO USED TO FOSTER THE GROWTH OF VEGETATION BY INCREASING AVAILABLE MOISTURE AND PROVIDING INSULATION AGAINST EXTREME HEAT AND COLD. MULCHING SHALL BE APPLIED THROUGHOUT CONSTRUCTION ON DENUDED AREAS. 5. SOIL STABILIZATION BLANKETS & MATTING - 3.36 BIODEGRADABLE MATTING INSTALLED OVER STEEP SLOPES TO HOLD THE EARTH AND SEED IN PLACE WHILE A GOOD STAND OF VEGETATION IS ESTABLISHED. PERMANENT MATTING SHALL BE INSTALLED IN AREAS WITH ANTICIPATED HIGH FLOW VELOCITIES UNDER FINAL PROJECT CONDITIONS. 1.10 PERMANENT STABILIZATION ALL AREAS WITHIN THE LIMITS OF DISTURBANCE SHALL BE STABILIZED WITH HARDSCAPE, LANDSCAPE MULCH, OR PERMANENT SEEDING WITH STRAW MULCH FOLLOWING FINAL GRADE. 1.11 CONSTRUCTION SEQUENCE 1.

ALL MATERIALS SPILLED, DROPPED, WASHED, OR TRACKED FROM VEHICLES ONTO ROADWAYS OR INTO STORM DRAINS MUST BE REMOVED IMMEDIATELY. THE USE OF WATER TRUCKS TO REMOVE MATERIALS DROPPED, WASHED, OR TRACKED ONTO ROADWAYS WILL NOT BE PERMITTED UNDER ANY CIRCUMSTANCES. 2. THE SILT FENCE BARRIERS SHALL BE CHECKED FOR UNDERMINING AND DETERIORATION OF OR DAMAGE TO THE FABRIC. DAMAGES SHALL BE IMMEDIATELY REPAIRED. SEDIMENT SHALL BE REMOVED WHEN THE LEVEL OF SEDIMENT DEPOSITION REACHES ONE HALF THE HEIGHT OF THE BARRIER. 3. THE SEDIMENT TRAP EMBANKMENT SHALL BE CHECKED REGULARLY FOR SIGNS OF EROSION AND THE SOUNDNESS OF THE EMBANKMENT. THE BASIN SHOULD BE CHECKED AFTER EACH RUNOFF -PRODUCING RAINFALL FOR SEDIMENT BUILD-UP. WHEN SEDIMENT REACHES THE CLEANOUT LEVEL, IT SHALL BE REMOVED AND PROPERLY DISPOSED OF. 4. ALL SEDIMENT REMOVED FROM TRAPPING MEASURES SHALL BE DEPOSITED IN A SUITABLE AREA AND IN SUCH A MANNER THAT IT WILL NOT ERODE OR CAUSE SEDIMENTATION PROBLEMS. 5. THE SEEDED AND MULCHED AREAS SHALL BE CHECKED REGULARLY TO ENSURE THAT A GOOD STAND IS MAINTAINED. AREAS SHOULD BE FERTILIZED AND RESEEDED AS NEEDED. REFER TO ESC TECHNICAL BULLETIN #4. PROVIDE REMEDIAL STABILIZATION AND SEEDING FOR A PERIOD OF ONE YEAR AFTER CONSTRUCTION. STORMWATER MANAGEMENT SUMMARY REFER TO THE SUPPLEMENTAL STORMWATER MANAGEMENT REPORT FOR A COMPLETE ANALYSIS OF THE STORMWATER MANAGEMENT COMPLIANCE AND SUPPORTING CALCULATIONS. THIS IS ONLY A SUMMARY OF THE COMPLIANCE STRATEGY. • CHANNEL PROTECTION - FOR THE CONCENTRATED DISCHARGE FROM THE BIORETENTION BASIN, COMPLIANCE WITH THE ENERGY BALANCE EQUATION WAS UTILIZED FOR DISCHARGES INTO A NATURAL CONVEYANCE SYSTEM. (9VAC25-870-66.B.3) • FLOOD PROTECTION - THE ONSITE AND DOWNSTREAM CONVEYANCE SYSTEMS WERE ANALYZED FOR CAPACITY DURING THE TEN-YEAR STORM EVENT TO A POINT WERE THE OVERALL DRAINAGE AREA IS OVER 100 TIMES THE SITE AREA. 9VAC25-870-66.C.1 • SHEET FLOW - ALL AREAS OF SHEET FLOW ARE BEING REDUCED IN THE POST -DEVELOPED CONDITION. (9VAC25-870-66.D) • WATER QUALITY - QUALITY REQUIREMENTS WILL BE MET THROUGH A LEVEL ONE BIORETENTION BASIN AND CONSERVATION OF OPEN SPACE ON THE PROPERTY. THE PROJECT IS ANTICIPATED TO PRODUCE A SURPLUS OF 0.88 POUNDS OF REMOVAL CREDITS.

PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. TEMPORARY SOIL STABILIZATION SHALL BE APPLIED WITHIN SEVEN DAYS TO DENUDED AREAS THAT MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT FOR LONGER THAN 14 DAYS. PERMANENT STABILIZATION SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR. MS-2. DURING CONSTRUCTION OF THE PROJECT, SOIL STOCK PILES AND BORROW AREAS SHALL BE STABILIZED OR PROTECTED WITH SEDIMENT TRAPPING MEASURES. THE APPLICANT IS RESPONSIBLE FOR THE TEMPORARY PROTECTION AND PERMANENT STABILIZATION OF ALL SOIL STOCKPILES ON SITE AS WELL AS BORROW AREAS AND SOIL INTENTIONALLY TRANSPORTED FROM THE PROJECT SITE. MS-3. A PERMANENT VEGETATIVE COVER SHALL BE ESTABLISHED ON DENUDED AREAS NOT OTHERWISE PERMANENTLY STABILIZED. PERMANENT VEGETATION SHALL NOT BE CONSIDERED ESTABLISHED UNTIL A GROUND COVER IS ACHIEVED THAT IS UNIFORM, MATURE ENOUGH TO SURVIVE AND WILL INHIBIT EROSION. MS-4. SEDIMENT BASINS AND TRAPS, PERIMETER DIKES, SEDIMENT BARRIERS AND OTHER MEASURES INTENDED TO TRAP SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP IN ANY LAND -DISTURBING ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE UPSLOPE LAND DISTURBANCE TAKES PLACE. MS-5. STABILIZATION MEASURES SHALL BE APPLIED TO EARTHEN STRUCTURES SUCH AS DAMS, DIKES AND DIVERSIONS IMMEDIATELY AFTER INSTALLATION. MS-6. SEDIMENT TRAPS AND SEDIMENT BASINS SHALL BE DESIGNED AND CONSTRUCTED BASED UPON THE TOTAL DRAINAGE AREA TO BE SERVED BY THE TRAP OR BASIN. A. THE MINIMUM STORAGE CAPACITY OF A SEDIMENT TRAP SHALL BE 134 CUBIC YARDS PER ACRE OF DRAINAGE AREA AND THE TRAP SHALL ONLY CONTROL DRAINAGE AREAS LESS THAN THREE ACRES. B. SURFACE RUNOFF FROM DISTURBED AREAS THAT IS COMPRISED OF FLOW FROM DRAINAGE AREAS GREATER THAN OR EQUAL TO THREE ACRES SHALL BE CONTROLLED BY A SEDIMENT BASIN. THE MINIMUM STORAGE CAPACITY OF A SEDIMENT BASIN SHALL BE 134 CUBIC YARDS PER ACRE OF DRAINAGE AREA. THE OUTFALL SYSTEM SHALL, AT A MINIMUM, MAINTAIN THE STRUCTURAL INTEGRITY OF THE BASIN DURING A 25-YEAR STORM OF 24-HOUR DURATION. RUNOFF COEFFICIENTS USED IN RUNOFF CALCULATIONS SHALL CORRESPOND TO A BARE EARTH CONDITION OR THOSE CONDITIONS EXPECTED TO EXIST WHILE THE SEDIMENT BASIN IS UTILIZED. MS-7. CUT AND FILL SLOPES SHALL BE DESIGNED AND CONSTRUCTED IN A MANNER THAT WILL MINIMIZE EROSION. SLOPES THAT ARE FOUND TO BE ERODING EXCESSIVELY WITHIN ONE YEAR OF PERMANENT STABILIZATION SHALL BE PROVIDED WITH ADDITIONAL SLOPE STABILIZING MEASURES UNTIL THE PROBLEM IS CORRECTED. MS-8. CONCENTRATED RUNOFF SHALL NOT FLOW DOWN CUT OR FILL SLOPES UNLESS CONTAINED WITHIN AN ADEQUATE TEMPORARY OR PERMANENT CHANNEL, FLUME OR SLOPE DRAIN STRUCTURE. MS-9. WHENEVER WATER SEEPS FROM A SLOPE FACE, ADEQUATE DRAINAGE OR OTHER PROTECTION SHALL BE PROVIDED. MS-10. ALL STORM SEWER INLETS THAT ARE MADE OPERABLE DURING CONSTRUCTION SHALL BE PROTECTED SO THAT SEDIMENT -LADEN WATER CANNOT ENTER THE CONVEYANCE SYSTEM WITHOUT FIRST BEING FILTERED OR OTHERWISE TREATED TO REMOVE SEDIMENT. MS-11. BEFORE NEWLY CONSTRUCTED STORMWATER CONVEYANCE CHANNELS OR PIPES ARE MADE OPERATIONAL, ADEQUATE OUTLET PROTECTION AND ANY REQUIRED TEMPORARY OR PERMANENT CHANNEL LINING SHALL BE INSTALLED IN BOTH THE CONVEYANCE CHANNEL AND RECEIVING CHANNEL. MS-12. WHEN WORK IN A LIVE WATERCOURSE IS PERFORMED, PRECAUTIONS SHALL BE TAKEN TO MINIMIZE ENCROACHMENT, CONTROL SEDIMENT TRANSPORT AND STABILIZE THE WORK AREA TO THE GREATEST EXTENT POSSIBLE DURING CONSTRUCTION. NONERODIBLE MATERIAL SHALL BE USED FOR THE CONSTRUCTION OF CAUSEWAYS AND COFFERDAMS. EARTHEN FILL MAY BE USED FOR THESE STRUCTURES IF ARMORED BY NONERODIBLE COVER MATERIALS. MS-1 3. WHEN A LIVE WATERCOURSE MUST BE CROSSED BY CONSTRUCTION VEHICLES MORE THAN TWICE IN ANY SIX-MONTH PERIOD, A TEMPORARY VEHICULAR STREAM CROSSING CONSTRUCTED OF NONERODIBLE MATERIAL SHALL BE PROVIDED. MS-14. ALL APPLICABLE FEDERAL, STATE AND LOCAL REQUIREMENTS PERTAINING TO WORKING IN OR CROSSING LIVE WATERCOURSES SHALL BE MET. MS-15. THE BED AND BANKS OF A WATERCOURSE SHALL BE STABILIZED IMMEDIATELY AFTER WORK IN THE WATERCOURSE IS COMPLETED. MS-16. UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN ACCORDANCE WITH THE FOLLOWING STANDARDS IN ADDITION TO OTHER APPLICABLE CRITERIA: A. NO MORE THAN 500 LINEAR FEET OF TRENCH MAY BE OPENED AT ONE TIME.

SITE WORK WILL INCLUDE CLEARING EXISTING TREES, EARTHWORK, AN ASPHALT PARKING LOT, CONCRETE PADS FOR RECYCLING CONTAINERS AND COMPACTORS, AN ATTENDANCE SHELTER, AND THE INSTALLATION OF UNDERGROUND ELECTRIC CONDUIT. THE PROJECT ALSO PROPOSES A BIORETENTION BASIN TO MEET STORMWATER MANAGEMENT REQUIREMENTS. THE PROJECT WILL HAVE A TOTAL DISTURBED AREA OF APPROXIMATELY 1.75 ACRES. WITHIN THE LIMITS OF DISTURBANCE, THERE ARE 0.01 ACRES CLASSIFIED AS IMPERVIOUS AREA, 0.18 ACRES CLASSIFIED AS MANAGED TURF, AND 1.56 ACRES CLASSIFIED AS FORESTED AREA IN THE EXISTING CONDITIONS. IN THE PROPOSED CONDITIONS, THERE ARE 0.80 ACRES CLASSIFIED AS MANAGED TURF AND 0.95 ACRES CLASSIFIED AS IMPERVIOUS AREA. IN ADDITION, 4.50 ACRES OF FORESTED AREA ON THE PROPERTY OUTSIDE THE LIMITS OF DISTURBANCE WILL BE PLACED IN A PERMANENT EASEMENT FOR PROTECTION. 1.2 EXISTING SITE CONDITIONS THE SITE IS LOCATED IN SOUTHERN ALBEMARLE COUNTY ON ESMONT ROAD. THE PROPERTY IS LOCATED SOUTH OF THE TOWN OF KEENE, WEST OF SCOTTSVILLE ROAD (ROUTE 20), AND EAST OF ESMONT ROAD. IN THE EXISTING CONDITIONS, THE PROPERTY IS MOSTLY FORESTED WITH A GRAVEUDIRT ROAD UNDER THE POWER LINES ACROSS THE FRONT TO THE SITE. A DIRT DRIVE EXTENDS TO THE EAST THROUGH THE MIDDLE OF THE SITE. THERE IS A HIGH POINT THROUGH THE MIDDLE OF THE SITE, FORCING THE RUNOFF FLOW EITHER TO THE NORTH OR SOUTH. THE EXISTING TOPOGRAPHY ON THE WEST END OF THE SITE RANGES FROM 1 % TO 8% WITH SLOPES GRADUALLY BECOMING STEEPER AS YOU MOVE AWAY FROM THE RIDGE RUNNING WEST TO EAST TO APPROXIMATELY 8% TO 16% SLOPES. 11.3ADJACENT PROPERTY THE PROPOSED SITE IS LOCATED IN SOUTHERN ALBEMARLE COUNTY. THE PROPERTIES BOARDING THE SITE ARE ALL CLASSIFIED AS RURAL AREAS. THE PROPERTY TO THE NORTH IS HEAVILY FORESTED WHILE THE PROPERTIES TO THE EAST AND SOUTH ARE A MIX OF FORESTED AND OPEN SPACE. THE SITE IS LOCATED APPROXIMATELY 800 FEET FROM THE INTERSECTION OF ESMONT ROAD AND SCOTTSVILLE ROAD. NO DISTURBANCE WILL TAKE PLACE ON ADJACENT PROPERTY. WITH PROPER SEDIMENT CONTROL IN PLACE TO CONTAIN SEDIMENT BEFORE LEAVING THE LIMITS OF CONSTRUCTION, NO ADVERSE EFFECTS RESULTING FROM SEDIMENT DEPOSITION IS ANTICIPATED FOR ANY OF THE ADJACENT OR DOWNSTREAM AREAS. 1.4 PLANNED OFF SITE ACTIVITIES THE PROJECT IS ANTICIPATED TO REQUIRE THE IMPORT OF FILL MATERIAL. ALL IMPORTED MATERIAL REQUIRED FOR BACKFILL, ETC., SHALL BE OBTAINED FROM A PREVIOUSLY PERMITTED OFF -SITE AREA OR A COMMERCIAL FACILITY. ALL EXCESS OR UNSUITABLE MATERIAL SHALL BE TRANSPORTED TO A PREVIOUSLY PERMITTED OFF -SITE DISPOSAL AREA. SHOULD ADDITIONAL OFF -SITE AREAS BE REQUIRED WHICH DO NOT HAVE AN EXISTING PERMIT, THEY SHALL HAVE SEPARATE EROSION AND SEDIMENT CONTROL PLANS APPROVED BY THE AUTHORITY HAVING JURISDICTION. THE NAMES OF ANY OFFSITE AREAS MUST BE PROVIDED TO ALBEMARLE COUNTY BEFORE ANY SOIL IS TRANSPORTED OFFSITE. THE CONTRACTOR SHALL BE RESPONSIBLE FOR IMPLEMENTING THE APPROVED EROSION AND SEDIMENT CONTROL PLAN ALONG WITH FINAL STABILIZATION AND MAINTENANCE OF ALL OFF -SITE AREAS. 1.5 SOILS A NATURAL RESOURCE CONSERVATION SERVICE (NRCS) CUSTOM SOIL RESOURCE REPORT FOR ALBEMARLE COUNTY, VIRGINIA DATED NOVEMBER 30, 2021 SHOWS THAT THE MAJORITY OF THE SOILS ON SITE ARE CLASSIFIED AS BUFFSTAT SILT LOAM WITH A HYDROLOGIC SOIL GROUP CLASSIFICATION OF B. A SMALL PORTION OF THE SOILS ON THE NORTHEAST AND SOUTHWEST SIDES OF THE SITE HAVE SOILS CLASSIFIED AS BUGLEY CHANNERY SILT LOAM WITH A HYDRAULIC SOIL GROUP CLASSIFICATION OF D. REFER TO APPENDIX C-1 FOR THE FULL SOIL REPORT. A FULL GEOTECHNICAL REPORT WAS ALSO COMPLETED FOR THE PROJECT AND WILL BE MADE AVAILABLE FOR THE CONTRACTOR'S USE 1.6 CRITICAL EROSION AREAS THE PROJECT WILL HAVE PROPOSED TIE IN SLOPES OF 3:1 THAT COULD BE CONSIDERED CRITICAL EROSION AREAS. REGULAR INSPECTIONS SHALL BE CONDUCTED ACROSS THE ENTIRE SITE TO ENSURE THE DISTURBED AND DOWNSTREAM SOILS DO NOT BECOME EROSIVE AS CONSTRUCTION PROGRESSES. IN GENERAL, THE CONTRACTOR SHALL MINIMIZE THE AREAS DISTURBED AT ONE TIME AND SHALL IMMEDIATELY APPLY SEED AND MULCH TO DENUDED AREAS AFTER WORK IS PERFORMED. 1.7 EROSION AND SEDIMENT CONTROL MEASURES UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO THE LATEST STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. UNLESS WAIVED OR APPROVED BY LOCAL ADMINISTRATOR, THE MINIMUM STANDARDS OF VESCR SHALL APPLY. 1.8 STRUCTURAL PRACTICES 1. TEMPORARY CONSTRUCTION ENTRANCE - 3.02 A STONE PAD, LOCATED AT THE POINT OF VEHICULAR INGRESS AND EGRESS TO THE CONSTRUCTION SITE. THE PURPOSE IS TO PREVENT OR REDUCE THE AMOUNT OF MUD TRANSPORTED TO THE PUBLIC ROAD. SEDIMENT DISLODGED OR WASHED FROM THE VEHICLE SHOULD BE CONTAINED WITHIN A PROPER SEDIMENT TRAPPING AREA. ALL VEHICLES ENTERING AND EXITING A DISTURBED AREA SHALL USE THE ENTRANCE. THE LOCATION OF THE ENTRANCE MAY NEED TO BE RELOCATED AS CONSTRUCTION PROGRESSES; COORDINATE LOCATIONS WITH INSPECTORS. 2. SILT FENCE - 3.05 SILT FENCE SEDIMENT BARRIERS WILL BE INSTALLED DOWN SLOPE OF DISTURBED AREAS TO FILTER SEDIMENT LADEN RUNOFF. 3. TEMPORARY DIVERSION DIKE - 3.09 TO BE INSTALLED TO DIVERT STORMWATER RUNOFF TO TRAPPING MEASURES BY CREATING A TEMPORARY RIDGE OF COMPACTED SOIL CONSTRUCTED AT THE TOP OR BASE OF A SLOPING DISTURBED AREA. THE LOCATION OF THE DIVERSIONS MAY NEED TO BE ALTERED THROUGHOUT CONSTRUCTION TO ENSURE THE MAXIMUM AMOUNT OF RUNOFF FROM THE DISTURBED AREA IS BEING CAPTURED BY A TRAPPING MEASURE. 4. TEMPORARY SEDIMENT TRAP - 3.13 TO BE USED WHEN THE DRAINAGE AREA IS LESS THAT THREE ACRES TO DETAIN SEDIMENT -LADEN RUNOFF FROM SMALL, DISTURBED AREAS LONG ENOUGH TO ALLOW SEDIMENT TO FILTER OUT OF THE RUNOFF. 4. CHECK DAMS - 3.20 SMALL TEMPORARY STONE DAMS CONSTRUCTED ACROSS DRAINAGE CHANNELS TO REDUCE VELOCITY OF CONCENTRATED FLOWS, AND THEREBY REDUCING EROSION OF THE CHANNEL. 5. SURFACE ROUGHENING - 3.29 APPLIED ON GRADED SLOPES TO AID IN ESTABLISHING VEGETATION, REDUCE RUNOFF VELOCITY AND EROSION, AND PROVIDE FOR SEDIMENT TRAPPING. A ROUGH SOIL IS CREATED BY CREATING HORIZONTAL DEPRESSIONS BY RUNNING A TRACKED PIECE OF EQUIPMENT UP AND DOWN THE SLOPES. 6. TREE PROTECTION - 3.38 A TEMPORARY FENCE INSTALLED AROUND TREES AND VEGETATION THAT WILL REMAIN TO PREVENT DAMAGE DURING CONSTRUCTION. THE FENCING WILL BE INSTALLED ALONG THE DRIP LINE OF THE TREE WHERE POSSIBLE. 7.

STORMWATER MANAGEMENT SUMMARY REFER TO THE SUPPLEMENTAL STORMWATER MANAGEMENT REPORT FOR A COMPLETE ANALYSIS OF THE STORMWATER MANAGEMENT COMPLIANCE AND SUPPORTING CALCULATIONS. THIS IS ONLY A SUMMARY OF THE COMPLIANCE STRATEGY. • CHANNEL PROTECTION - FOR THE CONCENTRATED DISCHARGE FROM THE BIORETENTION BASIN, COMPLIANCE WITH THE ENERGY BALANCE EQUATION WAS UTILIZED FOR DISCHARGES INTO A NATURAL CONVEYANCE SYSTEM. (9VAC25-870-66.B.3) • FLOOD PROTECTION - THE ONSITE AND DOWNSTREAM CONVEYANCE SYSTEMS WERE ANALYZED FOR CAPACITY DURING THE TEN-YEAR STORM EVENT TO A POINT WERE THE OVERALL DRAINAGE AREA IS OVER 100 TIMES THE SITE AREA. 9VAC25-870-66.C.1 • SHEET FLOW - ALL AREAS OF SHEET FLOW ARE BEING REDUCED IN THE POST -DEVELOPED CONDITION. (9VAC25-870-66.D) • WATER QUALITY - QUALITY REQUIREMENTS WILL BE MET THROUGH A LEVEL ONE BIORETENTION BASIN AND CONSERVATION OF OPEN SPACE ON THE PROPERTY. THE PROJECT IS ANTICIPATED TO PRODUCE A SURPLUS OF 0.88 POUNDS OF REMOVAL CREDITS.

The authorized discharge shall be in accordance with this cover page, Part I - Discharge Authorization and Special Conditions, Part II - Stormwater Pollution Prevention Plan, and Part III - Conditions Applicable to All VPDES Permits as set forth herein. General Permit No.: VAR10 Page 1 of 21 PART DISCHARGE AUTHORIZATION AND SPECIAL CONDITIONS A. Coverage under this general permit. 1. During the period beginning with the date of coverage under this general permit and lasting until the general permit's expiration date, the operator is authorized to discharge stormwater from construction activities. 2. This general permit also authorizes stormwater discharges from support activities (e.g., concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal areas, borrow areas) located on -site or off -site provided that: a. The support activity is directly related to the construction activity that is required to have general permit coverage for discharges of stormwater from construction activities; b. The support activity is not a commercial operation, nor does it serve multiple unrelated construction activities by different operators; c. The support activity does not operate beyond the completion of the last construction activity it supports; d. The support activity is identified in the registration statement at the time of general permit coverage; e. Appropriate control measures are identified in a stormwater pollution prevention plan and implemented to address the discharges from the support activity areas; and f. All applicable state, federal, and local approvals are obtained for the support activity. B. Limitations on coverage 1. Post -construction discharges. This general permit does not authorize stormwater discharges that originate from the site after construction activities have been completed and the site, including any support activity sites covered under the general permit registration, has undergone final stabilization. Post -construction industrial stormwater discharges may need to be covered by a separate VPDES permit. 2. Discharges mixed with nonstormwater. This general permit does not authorize discharges that are mixed with sources of nonstormwater, other than those discharges that are identified in Part I E (Authorized nonstormwater discharges) and are in compliance with this general permit. 3. Discharges covered by another state permit. This general permit does not authorize discharges of stormwater from construction activities that have been covered under an individual permit or required to obtain coverage under an alternative general permit. 4. Impaired waters and TMDL limitation. Discharges of stormwater from construction activities to surface waters identified as impaired in the 2012 § 305(b)/303(d) Water Quality Assessment Integrated Report or for which a TMDL wasteload allocation has been established and approved prior to the term of this general permit for (i) sediment or a sediment -related parameter (i.e., total suspended solids or turbidity) or (ii) nutrients (i.e., nitrogen or phosphorus) are not eligible for coverage under this general permit unless the operator develops, implements, and maintains a SWPPP that minimizes the pollutants of concern and, when applicable, is consistent with the assumptions and requirements of the approved TMDL wasteload allocations. In addition, the operator shall implement the following items: General Permit No.: VAR10 Page 2 of 21 a. The impaired water(s), approved TMDL(s), and pollutant(s) of concern, when applicable, shall be identified in the SWPPP; b. Permanent or temporary soil stabilization shall be applied to denuded areas within seven days after final grade is reached on any portion of the site; c. Nutrients shall be applied in accordance with manufacturer's recommendations or an approved nutrient management plan and shall not be applied during rainfall events; and d. The applicable SWPPP inspection requirements specified in Part II F 2 shall be amended as follows: (1) Inspections shall be conducted at a frequency of (i) at least once every four business days or (ii) at least once every five business days and no later than 48 hours following a measurable storm event. In the event that a measurable storm event occurs when there are more than 48 hours between business days, the inspection shall be conducted on the next business day; and (2) Representative inspections used by utility line installation, pipeline construction, or other similar linear construction activities shall inspect all outfalls discharging to surface waters identified as impaired or for which a TMDL wasteload allocation has been established and approved prior to the term of this general permit. 5. Exceptional waters limitation. Discharges of stormwater from construction activities not previously covered under the general permit issued in 2009 to exceptional waters identified in 9VAC25-260-30 A 3 c are not eligible for coverage under this general permit unless the operator implements the following: a. The exceptional water(s) shall be identified in the SWPPP; b. Permanent or temporary soil stabilization shall be applied to denuded areas within seven days after final grade is reached on any portion of the site; c. Nutrients shall be applied in accordance with manufacturer's recommendations or an approved nutrient management plan and shall not be applied during rainfall events; and d. The applicable SWPPP inspection requirements specified in Part II F 2 shall be amended as follows: (1) Inspections shall be conducted at a frequency of (i) at least once every four business days or (ii) at least once every five business days and no later than 48 hours following a measurable storm event. In the event that a measurable storm event occurs when there are more than 48 hours between business days, the inspection shall be conducted on the next business day; and (2) Representative inspections used by utility line installation, pipeline construction, or other similar linear construction activities shall inspect all outfalls discharging to exceptional waters. 6. There shall be no discharge of floating solids or visible foam in other than trace amounts. C. Commingled discharges. Discharges authorized by this general permit may be commingled with other sources of stormwater that are not required to be covered under a state permit, so long as the commingled discharge is in compliance with this general permit. Discharges authorized by a separate state or VPDES permit may be commingled with discharges authorized by this general permit so long as all such discharges comply with all applicable state and VPDES permit requirements. General Permit No.: VAR10 Page 3 of 21 D. Prohibition of nonstormwater discharges. Except as provided in Parts I A 2, 1 C, and I E, all discharges covered by this general permit shall be composed entirely of stormwater associated with construction activities. All other discharges including the following are prohibited: 1. Wastewater from washout of concrete; 2. Wastewater from the washout and cleanout of stucco, paint, form release oils, curing compounds, and other construction materials; 3. Fuels, oils, or other pollutants used in vehicle and equipment operation and maintenance; 4. Oils, toxic substances, or hazardous substances from spills or other releases; and 5. Soaps, solvents, or detergents used in equipment and vehicle washing. E. Authorized nonstormwater discharges. The following nonstormwater discharges from construction activities are authorized by this general permit when discharged in compliance with this general permit: 1. Discharges from firefighting activities; 2. Fire hydrant flushings; 3. Waters used to wash vehicles or equipment where soaps, solvents, or detergents have not been used and the wash water has been filtered, settled, or similarly treated prior to discharge; 4. Water used to control dust that has been filtered, settled, or similarly treated prior to discharge; 5. Potable water sources, including uncontaminated waterline flushings; 6. Routine external building wash down where soaps, solvents or detergents have not been used and the wash water has been filtered, settled, or similarly treated prior to discharge; 7.

A person is a duly authorized representative only if: a. The authorization is made in writing by a person described in Part III K 1; 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, operator of a well or a well field, superintendent, position of equivalent responsibility, or an individual or position having overall responsibility for environmental matters for the operator. (A duly authorized General Permit No.: VAR10 Page 18 of 21 representative may thus be either a named individual or any individual occupying a named position); and c. The signed and dated written authorization is included in the SWPPP. A copy must be provided to the department and VSMP authority, if requested. 3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because a different individual or position has responsibility for the overall operation of the construction activity, a new authorization satisfying the requirements of Part III K 2 shall be submitted to the VSMP authority as the administering entity for the board prior to or together with any reports or information to be signed by an authorized representative. 4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following certification: "I certify under penalty of law that I have read and understand this document and that this document and all attachments were prepared in accordance with a system designed to assure that qualified personnel properly gathered and evaluated 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." L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the Clean Water Act, except that noncompliance with certain provisions of this general permit may constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act. Permit noncompliance is grounds for enforcement action; for state permit termination, revocation and reissuance, or modification; or denial of a state permit renewal application. The operator shall comply with effluent standards or prohibitions established under § 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if this general permit has not yet been modified to incorporate the requirement. M. Duty to reapply. If the operator wishes to continue an activity regulated by this general permit after the expiration date of this general permit, the operator shall submit a new registration statement at least 90 days before the expiration date of the existing general permit, unless permission for a later date has been granted by the board. The board shall not grant permission for registration statements to be submitted later than the expiration date of the existing general permit. N. Effect of a state permit. This general permit does not convey any property rights in either real or personal property or any exclusive privileges, nor does it authorize any injury to private property or invasion of personal rights, or any infringement of federal, state or local law or regulations. O. State law. Nothing in this general permit shall be construed to preclude the institution of any legal action under, or relieve the operator from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Except as provided in general permit conditions on 'bypassing" (Part III U) and "upset' (Part III V), nothing in this general permit shall be construed to relieve the operator from civil and criminal penalties for noncompliance. P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to preclude the institution of any legal action or relieve the operator from any responsibilities, liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law or § 311 of the Clean Water Act. General Permit No.: VAR10 Page 19 of 21 Q. Proper operation and maintenance. The operator shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances), which are installed or used by the operator to achieve compliance with the conditions of this general permit. Proper operation and maintenance also includes effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems, which are installed by the operator only when the operation is necessary to achieve compliance with the conditions of this general permit. R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of treatment or management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such materials from entering surface waters and in compliance with all applicable state and federal laws and regulations. S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in violation of this general permit that has a reasonable likelihood of adversely affecting human health or the environment. T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this general permit. U. Bypass. 1. 'Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams from any portion of a treatment facility. The operator may allow any bypass to occur that does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and 3. 2. Notice. a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the operator shall submit prior notice to the department, if possible at least 10 days before the date of the bypass. b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as required in Part III I. 3. Prohibition of bypass. a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may take enforcement action against an operator for bypass unless: (1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage. Severe property damage means substantial physical damage to property, damage to the treatment facilities that causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production; (2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and (3) The operator submitted notices as required under Part III U 2. General Permit No.: VAR10 Page 20 of 21 b. The department may approve an anticipated bypass, after considering its adverse effects, if the department determines that it will meet the three conditions listed in Part III U 3 a. V. Upset. 1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is unintentional and temporary noncompliance with technology -based state permit effluent limitations because of factors beyond the reasonable control of the operator. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. 2. An upset constitutes an affirmative defense to an action brought for noncompliance with technology - based state permit effluent limitations if the requirements of Part III V 4 are met. A determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is not a final administrative action subject to judicial review. 3. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. 4. An operator who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs or other relevant evidence that: a. An upset occurred and that the operator can identify the cause(s) of the upset; b. The permitted facility was at the time being properly operated; c. The operator submitted notice of the upset as required in Part III I; and d. The operator complied with any remedial measures required under Part III S. 5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset has the burden of proof. W. Inspection and entry. The operator shall allow the department as the board's designee, the VSMP authority, EPA, or an authorized representative of either entity (including an authorized contractor), upon presentation of credentials and other documents as may be required by law to: 1. Enter upon the operator's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this general permit; 2. Have access to and copy, at reasonable times, any records that must be kept under the conditions of this general permit; 3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this general permit; and 4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management Act, any substances or parameters at any location. For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection unreasonable during an emergency. General Permit No.: VAR10 Page 21 of 21 X. State permit actions. State permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the operator for a state permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition. Y. Transfer of state permits. 1. State permits are not transferable to any person except after notice to the department. Except as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator only if the state permit has been modified or revoked and reissued, or a minor modification made, to identify the new operator and incorporate such other requirements as may be necessary under the Virginia Stormwater Management Act and the Clean Water Act. 2. As an alternative to transfers under Part III Y 1, this state permit maybe automatically transferred to a new operator if: a. The current operator notifies the department at least 30 days in advance of the proposed transfer of the title to the facility or property; b. The notice includes a written agreement between the existing and new operators containing specific date for transfer of state permit responsibility, coverage, and liability between them; and c. The department does not notify the existing operator and the proposed new operator of its intent to modify or revoke and reissue the state permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Part III Y 2 b. 3. For ongoing construction activity involving a change of operator, the new operator shall accept and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking over operations at the site. Z. Severability. The provisions of this general permit are severable, and if any provision of this general permit or the application of any provision of this state permit to any circumstance, is held invalid, the application of such provision to other circumstances and the remainder of this general permit shall not be affected thereby.
