Notice of general permit coverage (This notice is to be posted near the main entrance according to 9VAC25-880-70, Part II, section C.) (Provide a copy of the DEQ coverage letter when obtained) Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County Section 3. Nature of activity (Provide a detailed narrative of the construction activities. Include or reference a construction schedule and sequence. Include any phasing.) This project includes the establishment of three parcels and the development of two of the three parcels. Work associated with the two developed parcels under this plan consist of the construction of a hotel, a mini storage facility, required parking lots, and associated site features. The third lot will be graded but remain undeveloped at this time. The third lot, slated for future development, has an assumed impervious area accounted for in the water quantity calculations, but not the water quality calculations. Future improvements on the undeveloped lot will need to handle water quality independently. Also, a future shared use path is anticipated along Berkmar Drive. Impervious area associated with a 10' wide impervious path within the drainage area to the regional facility has been accounted for in water quantity calculations, while impervious area associated with the path along the entire frontage has been included in the water quality calculations. The majority of the site drains to an existing dry detention basin, County SWM facility ID 0021.01, which is located downhill and to the south of the site, between the bowling alley and Lowes home improvement store. This SWM facility will be used for stormwater quantity measurements and is within Deed of Easement (established right of County to Maintain), DB-PG: 1786-0734. For more information, please see County of Albemarle Deed of Easement with Keglers of Charlottesville, and Detention Pond Easement Plat, DB-PG: 1786-0737; plat by Wiley and Wilson, Lynchburg, April 15, 1994. Plan approval date of the facility is 11/19/87. Albemarle SWM facility database states existing dry detention basin watershed is 61.87 Ac. with 21.37 Ac. impervious; these values have been updated for use in our calculations based on a review of approved plans, GIS information, and site visits. The facility is listed in county SWM database (co -owned by) Keglers of Charlottesville and Lowes Investment Corp 4341. The project will disturb 5.47 acres. There are 0.35 acres of impervious area associated with a gravel/paved access road, while the rest of the site is assumed forested. In the proposed conditions there will be 2.58 acres of managed turf and 2.89 acres of impervious. These values include the impervious area associated with the shared use path, but not development associated with the third platted parcel. The required phosphorus removal for the work shown on these plans is 5.19 lb/yr. The requirement will be satisfied with the purchase of credits from an offsite nutrient bank. The project site is bounded by Berkmar drive to the North, commercial building to the West, East, and South. All construction shall take place in accordance with the Erosion and Sediment Control Sequence of Installation on plan sheet C3.3 — C3.5. Estimated construction dates are as indicated on the Registration Statement. Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County Section 4.

Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County Bacteria TMDL Development for the Rivanna River Mainstem, North Fork Rivanna River, Preddy Creek and Tributaries, Meadow Creek, Mechums River, and Beaver Creek Watersheds Submitted by Virginia Department of Environmental Quality Prepared by THE Louis Berger Group, INC. 2445 M Street, NW Washington, DC 20037 Final Report March 2008 Executive Summary This report presents the development of bacteria TMDLs for the Rivanna River mainstem, North Fork Rivanna River, Preddy Creek and tributaries, Meadow Creek, Mechums River, and Beaver Creek watersheds. 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. This segment of Beaver Creek was first listed on the 2004 305(b)/303(d) Water Quality Assessment Integrated Report for exceedances of the fecal coliform standard. 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 MI. 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 MI. 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 cf i/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 mi. 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 cfu/100 mi. 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. coh. Virginia's bacteria water quality standard currently states that E. coli bacteria shall not exceed a geometric mean of 126 E. coh counts per 100 mL of water for two or more samples within a calendar month, or an E. coh 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. coh concentrations using an in -stream translator. This TMDL was required to meet both the geometric mean and instantaneous E. colt 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 e delineating the watershed into smaller subwatersheds e entering the physical data that describe each subwatershed and stream segment e 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 stone 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 = Y, WLA +Y 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.

Implementation will occur in stages. 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.

The operator shall give notice to the department and the VSMP authority as soon as possible of any planned physical alterations or additions to the permitted facility or activity. Notice is required only when: a. The operator plans an alteration or addition to any building, structure, facility, or installation that may meet one of the criteria for determining whether a facility is a new source in 9VAC25-870-420; b. The operator plans an alteration or addition that would significantly change the nature or increase the quantity of pollutants discharged. This notification applies to pollutants that are not subject to effluent limitations in this general permit; or 2. The operator shall give advance notice to the department and VSMP authority of any planned changes in the permitted facility or activity, which may result in noncompliance with state permit requirements. K. Signatory requirements. 1. Registration statement. All registration statements shall be signed as follows: a. For a corporation: by a responsible corporate officer. For the purpose of this chapter, a responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy -making or decision -making functions for the corporation; or (ii) the manager of one or more manufacturing, production, or operating facilities, provided the Page 22 of 26 manager is authorized to make management decisions that govern the operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long-term compliance with environmental laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information for state permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures; b. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively; or c. For a municipality, state, federal, or other public agency: by either a principal executive officer or ranking elected official. For purposes of this chapter, a principal executive officer of a public agency includes (i) the chief executive officer of the agency or (ii) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency. 2. Reports and other information. All reports required by this general permit, including SWPPPs, and other information requested by the board or the department shall be signed by a person described in Part III K 1 or by a duly authorized representative of that person. 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 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 shall 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 Page 23 of 26 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 coverage, 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 60 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. 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. Page 24 of 26 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. 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. Page 25 of 26 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 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 shall be kept under the conditions of this general permit; 2. Have access to and copy, at reasonable times, any records that shall 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. Page 26 of 26 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. X. State permit actions. State permit coverage 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 permit coverage. 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. As an alternative to transfers under Part III Y 1, this state permit may be 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 a 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. Section 12. Inspection logs INSPECTION FREQUENCY: (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.

THE LIMITS OF DISTURBANCE IS 5.47 ACRES. ADJACENT PROPERTY THE PROJECT SITE IS BOUND BY BERKMAR DRIVE TO THE WEST AND COMMERCIAL BUILDINGS TO THE NORTH, EAST AND SOUTH. EXISTING SITE CONDITIONS THE EXISTING SITE IS CURRENTLY WOODED AREA. SLOPES GENERALLY RANGE FROM 10-15% TO THE SOUTHEAST. OFF -SITE AREAS WORK TO THE REGIONAL BASIN IS OFF THE PROPERTY, BUT INCLUDED WITHIN THE LIMITS OF DISTURBANCE. THE PROJECT HAS BEEN DESIGNED SUCH THAT THE EARTHWORK CALCULATIONS SHOW A BALANCED SITE. THEREFORE, WE ANTICIPATE LIMITED NEED FOR OFF -SITE BORROW OR HAUL LOCATIONS UNLESS UNEXPECTED CONDITIONS ARISE. IF ADDITIONAL FILL OR TOPSOIL MATERIAL IS REQUIRED TO BE IMPORTED FROM AN AREA OUTSIDE THE LIMITS OF DISTURBANCE OR IF CUT MATERIAL IS GENERATED, IT MUST BE TO / FROM A LOCATION WITH AN APPROVED EROSION AND SEDIMENT CONTROL PLANS, A LAND DISTURBING PERMIT, AND A VSMP PERMIT. THIS LOCATION MUST BE IDENTIFIED, PROVIDED TO THE COUNTY FOR REVIEW, AND APPROVED PRIOR TO ANY MATERIAL LEAVING OR ENTERING THE SITE FROM AN OFFSITE AREA. ALL MATERIALS RESULTING FROM DEMOLITION WORK, EXCEPT AS INDICATED OR SPECIFIED OTHERWISE, SHALL BECOME THE PROPERTY OF THE CONTRACTOR, SHALL BE REMOVED FROM THE PROPERTY, AND SHALL BE DISPOSED OF IN ACCORDANCE WITH APPLICABLE LOCAL, STATE, AND FEDERAL REGULATIONS. CRITICAL EROSION AREAS STEEP SLOPES UP TO 2:1 WILL BE CREATED DURING CONSTRUCTION, WHICH ARE CRITICAL AREAS PRONE TO EROSION IF NOT MAINTAINED AND STABILIZED PROPERLY. THE CONTRACTOR SHALL MAKE REPAIRS AND / OR ADJUSTMENTS TO THE PROPOSED ON -SITE EROSION AND SEDIMENT CONTROL MEASURES AS REQUIRED TO ESTABLISH STABILIZATION ON THESE SLOPES. EROSION AND SEDIMENT CONTROL MEASURES UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION AND SEDIMENT CONTROL PRACTICES SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO MINIMUM STANDARDS AND SPECIFICATIONS OF THE CURRENT ADDITION OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. THE MINIMUM STANDARDS OF THE VESCH SHALL BE ADHERED TO UNLESS OTHERWISE WAIVED OR APPROVED BY A VARIANCE BY LOCAL AUTHORITIES HAVING JURISDICTION. EROSION AND SEDIMENT CONTROL MAINTENANCE ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE MAINTAINED IN ACCORDANCE WITH VESCH AND THE CONSTRUCTION SEQUENCE, INCLUDING THE INSPECTION OF ALL MEASURES AFTER ALL RAIN EVENTS. STRUCTURAL PRACTICES: 1. TEMPORARY CONSTRUCTION ENTRANCE - 3.02 A TEMPORARY CONSTRUCTION ENTRANCE SHALL BE PROVIDED AT THE LOCATION INDICATED ON THE PLANS. IT IS IMPERATIVE THAT THIS MEASURE BE MAINTAINED THROUGHOUT CONSTRUCTION. ITS PURPOSE IS TO REDUCE THE AMOUNT OF MUD TRANSPORTED ONTO PAVED PUBLIC ROADS BY MOTOR VEHICLES OR RUNOFF. 2. SILT FENCE - 3.05 SILT FENCE SEDIEMENT BARRIERS SHALL BE INSTALLED DOWNSLOPE OF AREAS WITH MINIMAL GRADES TO FILTER SETTLEMENT LADEN RUNOFF FROM SHEET FLOW AS INDICATED. ITS PURPOSE IS TO PREVENT SEDIMENT FROM LEAVING THE SITE. 3. STORM DRAIN INLET PROTECTION - 3.07 FILTERS SHALL BE PLACED AT THE INLET OF ALL DRAINAGE STRUCTURES AS INDICATED ON PLANS. ITS PURPOSE IS TO PREVENT SEDIMENT FROM ENTERING THE STORM DRAINAGE SYSTEM PRIOR TO PERMANENT STABILIZATION. 4. DIVERSION DIKE - 3.09 A TEMPORARY RIDGE OF COMPACTED SOIL TO DIVERT WATER FROM A CERTAIN AREA. 5. TEMPORARY SEDIMENT TRAP - 3.13 A TEMPORARY BARRIER OR DAM WITH A CONTROLLED STORMWATER RELEASE TO DETAIN SEDIMENT -LADEN RUNOFF FROM DISTURBED AREAS IN "WET' AND "DRY" STORAGE LONG ENOUGH FOR THE MAJORITY OF SEDIMENT TO SETTLE OUT. MAINTENANCE OF SEDIMENT TRAP - INSPECT TRAP EMBANKMENT WEEKLY TO ENSURE IT IS STRUCTURALLY SOUND AND HAS NOT BEEN DAMAGED DURING CONSTRUCTION ACTIVITIES. THE TRAP SHALL BE CHECKED AFTER EVERY RAINFALL EVENT. ONCE THE SEDIMENT HAS REACHED THE DESIGNATED CLEANOUT LEVEL IT SHALL BE REMOVED AND PROPERLY DISPOSED OF. 6. STORMWATER CONVEYANCE CHANNEL - 3.17 PERMANENT CHANNEL WITH APPROPRIATE LINING TO CONVEY CONCENTRATED STORMWATER FLOWS WITHOUT EROSION. 7. OUTLET PROTECTION - 3.18 STRUCTURALLY LINED APRONS PLACED AT THE OUTLETS OF PIPES OR CHANNEL SECTION TO PREVENT SCOUR AND PROTECT THE OUTLETS STRUCTURE. 8.

THE THIRD LOT WILL BE GRADED BUT REMAIN UNDEVELOPED AT THIS TIME. THE THIRD LOT, SLATED FOR FUTURE DEVELOPMENT, HAS AN ASSUMED IMPERVIOUS AREA ACCOUNTED FOR IN THE WATER QUANTITY CALCULATIONS, BUT NOT THE WATER QUALITY CALCULATIONS. FUTURE IMPROVEMENTS ON THE UNDEVELOPED LOT WILL NEED TO HANDLE WATER QUALITY INDEPENDENTLY. ALSO, A FUTURE SHARED USE PATH IS ANTICIPATED ALONG BERKMAR DRIVE. IMPERVIOUS AREA ASSOCIATED WITH A 10' WIDE IMPERVIOUS PATH WITHIN THE DRAINAGE AREA TO THE REGIONAL FACILITY HAS BEEN ACCOUNTED FOR IN WATER QUANTITY CALCULATIONS, WHILE IMPERVIOUS AREA ASSOCIATED WITH THE PATH ALONG THE ENTIRE FRONTAGE HAS BEEN INCLUDED IN THE WATER QUALITY CALCULATIONS. THE MAJORITY OF THE SITE DRAINS TO AN EXISTING DRY DETENTION BASIN, COUNTY SWM FACILITY ID 0021.01, WHICH IS LOCATED DOWNHILL AND TO THE SOUTH OF THE SITE, BETWEEN THE BOWLING ALLEY AND LOWES HOME IMPROVEMENT STORE. THIS POND WILL BE USED FOR STORMWATER QUANTITY MEASUREMENTS AND IS WITHIN DEED OF EASEMENT (ESTABLISHED RIGHT OF COUNTY TO MAINTAIN), DB-PG: 1786-0734.

This letter is to certify that as the date of this letter, Ivy Creek Nutrient Bank has 161.34 pounds of phosphorus (TP), 248.28 pounds of nitrogen (TN), and 50,875.5 pounds of TSS available fortransfer to those entities requiring offsets in accordance with the Chesapeake Bay Watershed Nutrient Credit Exchange Program (VA Code § 62.1-44.19:14 et seq.). Those offsets are also transferable in accordance with the Virginia stormwater offset program (VA Code § 62.1-44.15:35) and the Virginia Soil and Water Conservation Board's Guidance Document on Stormwater Nonpoint Nutrient Offsets approved on July 23, 2009, to those regulated entities qualifying for nutrient credits. We can certainly accommodate your needs and could offer to fulfil the order of 5.19 pounds of phosphorus. Please feel free to contact us with any questions. I hope we have the opportunity to work together on this project. Sincerely, Ecosystem Services, LLC By: Lp'' * ^ 1� Jonathan R.
