Stormwater Management Plan 1. Through the use of engineered level spreaders,the stormwater from this site is released as sheet flow without causing down- gradient erosion or sedimentation, meeting requirement 9VAC25-870-66D. 2. Water quality will be addressed by the dedication of 2.65 acres of existing vacant land within the property into a SWM forest/open space easement.This 2.65 acre easement will be located near the eastern portion of the property and shall be subject to standard Albemarle County open space deeds requirements.With this area of forest,the VRRM spreadsheet shows that there is no further treatment necessary for this project.Thus this development is in compliance with 9VAC25-870-63.

Persons responsible for pollution prevention practices Owner of Record, Christian& Pamela Comberg F. Response and reporting practices • Minimize discharges from spills and leaks. Minimize the discharge of pollutants from spills and leaks and implement chemical spill and leak prevention and response procedures as follows. To the extent practical, do not store oils, chemicals, or other potential contaminants on site. When storage of potential contaminants is required, provide secondary containment, such as spill berms or spill containment pallets. These should be located within the drainage areas to a sediment trap or sediment basin. Direct concrete wash water into a settling basin, dispose of hardened concrete with other construction waste debris to an appropriate waste facility. Respond to all spills, leaks and discharges as follows. Spills of oil,petroleum products, sanitary wastes, and substances listed under 40 CFR parts 110, 117, and 302 should be cleaned up as soon as possible while protecting worker safety. Construct an earthen dike around any spills on dirt to prevent spreading. If a spill occurs during rainfall, cover it with a tarp or another impermeable cover to prevent contaminating runoff. Do not bury any spills or wash them with water. Maintain a spill kits in a readily accessible location. A spill kit shall consist of a lined drum with bags of universal sorbents in the bottom, accessible without tipping the drum, sorbent socks above the bags, and personal protective equipment on the top. All materials used to remove the contaminants, including any water used to rinse equipment, and all dirt removed must be treated as contaminated. Textiles, such as from coveralls, may be sent to a certified laundry facility. Waste must be disposed of according to the standards of The City of Charlottesville and the Commonwealth of Virginia. Store hazardous materials and wastes in covered containers. Report all spills, leaks and discharges as follows: All spills, leaks, and discharges shall be recorded in the inspection logs. If construction activity results in a discharge of contaminants that may be reasonably expected to enter surface waters, the operator shall notify the Department of Environmental Quality immediately or within 24 hours, and shall submit a written report within five days. For significant spills that cannot be controlled by personnel in the immediate vicinity, notify the local emergency response by dialing 911. The City of Charlottesville must also be notified, and potentially some of the following agencies: the Fire Department, the Public Works Department,the Coast Guard, the Highway Patrol,the County Police Department, Department of Toxic Substances, OSHA,etc. For spills of federal reportable quantities, in conformance with the requirements in 40 CFR parts 110, 119, and 302, the contractor should notify the National Response Center at(800)424-8802. G. Pollution Prevention Awareness The engineer,project superintendent, and contractor shall have weekly meetings to review on-site conditions and advise contractor of potential risks that should be addressed. Contractor will be responsible for following procedures on a daily basis and applying appropriate waste management and prevention practices to be in compliance with the conditions of the general permit. Employees shall be informed of the danger to nature and to human health of various chemical spills. Section 7. Discharges to impaired waters, surface waters within an applicable TMDL wasteload allocation, and exceptional waters. The site discharges to an impaired water, North Fork Rivanna River. Causes of impairment are Escherischia coli and benthic-macroinvertebrate bioassessments. Site work shall be in compliance with the following requirements: 1. 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; 2. 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 3. In accordance with Part I B 4 and Part I B 5, inspections shall be conducted as follows: I. 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 II. Representative inspections used by utility line installation,pipeline construction,or other similar linear construction activities shall inspect all outfalls discharging to exceptional waters.

Areas that have reached final stabilization and where no further SWPPP or inspection requirements apply; d. All properties that are no longer under the legal control of the operator and the dates on which the operator no longer had legal control over each property; e. The date of any prohibited discharges, the discharge volume released, and what actions were taken to minimize the impact of the release; f. Measures taken to prevent the reoccurrence of any prohibited discharge; and g. Measures taken to address any evidence identified as a result of an inspection required under Part II F. General Permit No.: VAR10 Page 10 of 23 5. Amendments, modifications, or updates to the SWPPP shall be signed in accordance with Part III K. C. Public Notification. Upon commencement of land disturbance, the operator shall post conspicuously a copy of the notice of coverage letter near the main entrance of the construction activity. For linear projects, the operator shall post the notice of coverage letter at a publicly accessible location near an active part of the construction project (e.g., where a pipeline crosses a public road). The operator shall maintain the posted information until termination of general permit coverage as specified in Part I F. D. SWPPP availability. 1. Operators with day-to-day operational control over SWPPP implementation shall have a copy of the SWPPP available at a central location on-site for use by those identified as having responsibilities under the SWPPP whenever they are on the construction site. 2. The operator shall make the SWPPP and all amendments, modifications, and updates available upon request to the department, the VSMP authority, the EPA, the VESCP authority, local government officials, or the operator of a municipal separate storm sewer system receiving discharges from the construction activity. If an on-site location is unavailable to store the SWPPP when no personnel are present, notice of the SWPPP's location must be posted near the main entrance of the construction site. 3. The operator shall make the SWPPP available for public review in an electronic format or in hard copy. Information for public access to the SWPPP shall be posted and maintained in accordance with Part II C. If not provided electronically, public access to the SWPPP may be arranged upon request at a time and at a publicly accessible location convenient to the operator or his designee but shall be no less than once per month and shall be during normal business hours. Information not required to be contained within the SWPPP by this general permit is not required to be released. E. SWPPP implementation. The operator shall implement the SWPPP and subsequent amendments, modifications, and updates from commencement of land disturbance until termination of general permit coverage as specified in Part I F. 1. All control measures must be properly maintained in effective operating condition in accordance with good engineering practices and, where applicable, manufacturer specifications. If a site inspection required by Part II F identifies a control measure that is not operating effectively, corrective action(s) shall be completed as soon as practicable, but no later than seven days after discovery or a longer period as established by the VSMP authority, to maintain the continued effectiveness of the control measures. 2. If site inspections required by Part II F identify an existing control measure that needs to be modified or if an additional control measure is necessary for any reason, implementation shall be completed prior to the next anticipated measurable storm event. If implementation prior to the next anticipated measurable storm event is impracticable, then alternative control measures shall be implemented as soon as practicable, but no later than seven days after discovery or a longer period as established by the VSMP authority. F. SWPPP Inspections. 1. Personnel responsible for on-site and off-site inspections. Inspections required by this general permit shall be conducted by the qualified personnel identified by the operator in the SWPPP. The operator is responsible for insuring that the qualified personnel conduct the inspection. 2. Inspection schedule. a. Inspections shall be conducted at a frequency of: General Permit No.: VAR10 Page 11 of 23 (1) At least once every five business days; or (2) At least once every 10 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 no later than the next business day. b. Where areas have been temporarily stabilized or land-disturbing activities will be suspended due to continuous frozen ground conditions and stormwater discharges are unlikely, the inspection frequency may be reduced to once per month. If weather conditions (such as above freezing temperatures or rain or snow events) make discharges likely, the operator shall immediately resume the regular inspection frequency. c. Representative inspections may be utilized for utility line installation, pipeline construction, or other similar linear construction activities provided that: (1) Temporary or permanent soil stabilization has been installed and vehicle access may compromise the temporary or permanent soil stabilization and potentially cause additional land disturbance increasing the potential for erosion; (2) Inspections occur on the same frequency as other construction activities; (3) Control measures are inspected along the construction site 0.25 miles above and below each access point (i.e., where a roadway, undisturbed right-of-way, or other similar feature intersects the construction activity and access does not compromise temporary or permanent soil stabilization); and (4) Inspection locations are provided in the report required by Part II F. 3. Inspection requirements. a. As part of the inspection, the qualified personnel shall: (1) Record the date and time of the inspection and when applicable the date and rainfall amount of the last measurable storm event; (2) Record the information and a description of any discharges occurring at the time of the inspection; (3) Record any land-disturbing activities that have occurred outside of the approved erosion and sediment control plan; (4) Inspect the following for installation in accordance with the approved erosion and sediment control plan, identification of any maintenance needs, and evaluation of effectiveness in minimizing sediment discharge, including whether the control has been inappropriately or incorrectly used: (a) All perimeter erosion and sediment controls, such as silt fence; (b) Soil stockpiles, when applicable, and borrow areas for stabilization or sediment trapping measures; (c) Completed earthen structures, such as dams, dikes, ditches, and diversions for stabilization; General Permit No.: VAR10 Page 12 of 23 (d) Cut and fill slopes; (e) Sediment basins and traps, sediment barriers, and other measures installed to control sediment discharge from stormwater; (f) Temporary or permanent channel, flume, or other slope drain structures installed to convey concentrated runoff down cut and fill slopes; (g) Storm inlets that have been made operational to ensure that sediment laden stormwater does not enter without first being filtered or similarly treated; and (h) Construction vehicle access routes that intersect or access paved roads for minimizing sediment tracking; (5) Inspect areas that have reached final grade or that will remain dormant for more than 14 days for initiation of stabilization activities; (6) Inspect areas that have reached final grade or that will remain dormant for more than 14 days for completion of stabilization activities within seven days of reaching grade or stopping work; (7) Inspect for evidence that the approved erosion and sediment control plan, "agreement in lieu of a plan," or erosion and sediment control plan prepared in accordance with department- approved annual standards and specifications has not been properly implemented. This includes but is not limited to: (a) Concentrated flows of stormwater in conveyances such as rills, rivulets or channels that have not been filtered, settled, or similarly treated prior to discharge, or evidence thereof; (b) Sediment laden or turbid flows of stormwater that have not been filtered or settled to remove sediments prior to discharge; (c) Sediment deposition in areas that drain to unprotected stormwater inlets or catch basins that discharge to surface waters. Inlets and catch basins with failing sediments controls due to improper installation, lack of maintenance, or inadequate design are considered unprotected; (d) Sediment deposition on any property (including public and private streets) outside of the construction activity covered by this general permit; (e) Required stabilization has not been initiated or completed on portions of the site; (f) Sediment basins without adequate wet or dry storage volume or sediment basins that allow the discharge of stormwater from below the surface of the wet storage portion of the basin; (g) Sediment traps without adequate wet or dry storage or sediment traps that allow the discharge of stormwater from below the surface of the wet storage portion of the trap; and (h) Land disturbance outside of the approved area to be disturbed; (8) Inspect pollutant generating activities identified in the pollution prevention plan for the proper implementation, maintenance and effectiveness of the procedures and practices; (9) Identify any pollutant generating activities not identified in the pollution prevention plan; and General Permit No.: VAR10 Page 13 of 23 (10) Identify and document the presence of any evidence of the discharge of pollutants prohibited by this general permit. 4. Inspection report. Each inspection report shall include the following items: a. The date and time of the inspection and when applicable, the date and rainfall amount of the last measurable storm event; b. Summarized findings of the inspection; c. The location(s)of prohibited discharges; d. The location(s)of control measures that require maintenance; e. The location(s) of control measures that failed to operate as designed or proved inadequate or inappropriate for a particular location; f. The location(s)where any evidence identified under Part II F 3 a(7)exists; g. The location(s) where any additional control measure is needed that did not exist at the time of inspection; h. A list of corrective actions required (including any changes to the SWPPP that are necessary) as a result of the inspection or to maintain permit compliance; i. Documentation of any corrective actions required from a previous inspection that have not been implemented; and j. The date and signature of the qualified personnel and the operator or its duly authorized representative. The inspection report and any actions taken in accordance with Part II must be retained by the operator as part of the SWPPP for at least three years from the date that general permit coverage expires or is terminated. The inspection report shall identify any incidents of noncompliance. Where an inspection report does not identify any incidents of noncompliance, the report shall contain a certification that the construction activity is in compliance with the SWPPP and this general permit. The report shall be signed in accordance with Part III K of this general permit. G. Corrective actions. 1. The operator shall implement the corrective action(s) identified as a result of an inspection as soon as practicable but no later than seven days after discovery or a longer period as approved by the VSMP authority. If approval of a corrective action by a regulatory authority (e.g., VSMP authority, VESCP authority, or the department) is necessary, additional control measures shall be implemented to minimize pollutants in stormwater discharges until such approvals can be obtained. 2. The operator may be required to remove accumulated sediment deposits located outside of the construction activity covered by this general permit as soon as practicable in order to minimize environmental impacts. The operator shall notify the VSMP authority and the department as well as obtain all applicable federal, state, and local authorizations, approvals, and permits prior to the removal of sediments accumulated in surface waters including wetlands. General Permit No.: VAR10 Page 14 of 23 PART III CONDITIONS APPLICABLE TO ALL VPDES PERMITS NOTE: Discharge monitoring is not required for this general permit.

Monitoring results shall be reported on a discharge monitoring report (DMR); on forms provided, approved or specified by the department; or in any format provided that the date, location, parameter, method, and result of the monitoring activity are included. General Permit No.: VAR10 Page 15 of 23 3. If the operator monitors any pollutant specifically addressed by this general permit more frequently than required by this general permit using test procedures approved under 40 CFR Part 136 or using other test procedures approved by the U.S. Environmental Protection Agency or using procedures specified in this general permit, the results of this monitoring shall be included in the calculation and reporting of the data submitted in the DMR or reporting form specified by the department. 4. Calculations for all limitations which require averaging of measurements shall utilize an arithmetic mean unless otherwise specified in this general permit. D. Duty to provide information. The operator shall furnish, within a reasonable time, any information which the board may request to determine whether cause exists for modifying, revoking and reissuing, or terminating this general permit or to determine compliance with this general permit. The board, department, EPA, or VSMP authority may require the operator to furnish, upon request, such plans, specifications, and other pertinent information as may be necessary to determine the effect of the wastes from his discharge on the quality of surface waters, or such other information as may be necessary to accomplish the purposes of the CWA and the Virginia Stormwater Management Act. The operator shall also furnish to the board, department, EPA, or VSMP authority, upon request, copies of records required to be kept by this general permit. E. Compliance schedule reports. Reports of compliance or noncompliance with, or any progress reports on, interim and final requirements contained in any compliance schedule of this general permit shall be submitted no later than 14 days following each schedule date. F. Unauthorized stormwater discharges. Pursuant to § 62.1-44.5 of the Code of Virginia, except in compliance with a state permit issued by the department, it shall be unlawful to cause a stormwater discharge from a construction activity. G. Reports of unauthorized discharges. Any operator who discharges or causes or allows a discharge of sewage, industrial waste, other wastes or any noxious or deleterious substance or a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110, 40 CFR Part 117, 40 CFR Part 302, or§ 62.1-44.34:19 of the Code of Virginia that occurs during a 24-hour period into or upon surface waters or who discharges or causes or allows a discharge that may reasonably be expected to enter surface waters, shall notify the Department of Environmental Quality of the discharge immediately upon discovery of the discharge, but in no case later than within 24 hours after said discovery. A written report of the unauthorized discharge shall be submitted to the department and the VSMP authority within five days of discovery of the discharge. The written report shall contain: 1. A description of the nature and location of the discharge; 2. The cause of the discharge; 3. The date on which the discharge occurred; 4. The length of time that the discharge continued; 5. The volume of the discharge; 6. If the discharge is continuing, how long it is expected to continue; 7. If the discharge is continuing, what the expected total volume of the discharge will be; and 8. Any steps planned or taken to reduce, eliminate and prevent a recurrence of the present discharge or any future discharges not authorized by this general permit. General Permit No.: VAR10 Page 16 of 23 Discharges reportable to the department and the VSMP authority under the immediate reporting requirements of other regulations are exempted from this requirement. H. Reports of unusual or extraordinary discharges. If any unusual or extraordinary discharge including a "bypass" or "upset," as defined herein, should occur from a facility and the discharge enters or could be expected to enter surface waters, the operator shall promptly notify, in no case later than within 24 hours, the department and the VSMP authority by telephone after the discovery of the discharge. This notification shall provide all available details of the incident, including any adverse effects on aquatic life and the known number of fish killed. The operator shall reduce the report to writing and shall submit it to the department and the VSMP authority within five days of discovery of the discharge in accordance with Part III 12. Unusual and extraordinary discharges include but are not limited to any discharge resulting from: 1. Unusual spillage of materials resulting directly or indirectly from processing operations; 2. Breakdown of processing or accessory equipment; 3. Failure or taking out of service of some or all of the facilities; and 4. Flooding or other acts of nature. I. Reports of noncompliance.

The following shall be included as information that shall be reported within 24 hours under this subdivision: a. Any unanticipated bypass; and b. Any upset that causes a discharge to surface waters. 2. A written report shall be submitted within five days and shall contain: a. A description of the noncompliance and its cause; b. The period of noncompliance, including exact dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue; and c. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance. The department may waive the written report on a case-by-case basis for reports of noncompliance under Part III I if the oral report has been received within 24 hours and no adverse impact on surface waters has been reported. 3. The operator shall report all instances of noncompliance not reported under Part III 11 or 2 in writing as part of the SWPPP. The reports shall contain the information listed in Part III 12. NOTE: The reports required in Part III G, H and I shall be made to the department and the VSMP authority. Reports may be made by telephone, email, or by fax. For reports outside normal working hours, leaving a recorded message shall fulfill the immediate reporting requirement. For emergencies, the Virginia Department of Emergency Management maintains a 24-hour telephone service at 1-800-468- 8892. General Permit No.: VAR10 Page 17 of 23 4. Where the operator becomes aware of a failure to submit any relevant facts, or submittal of incorrect information in any report, including a registration statement, to the department or the VSMP authority, the operator shall promptly submit such facts or correct information. J. Notice of planned changes. 1. 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 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, etc. 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 Ill 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 General Permit No.: VAR10 Page 18 of 23 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 23 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 23 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 23 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 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. General Permit No.: VAR10 Page 22 of 23 DEFINITIONS "Business day" means Monday through Friday excluding state holidays. "Commencement of land disturbance" means the initial disturbance of soils associated with clearing, grading, or excavating activities or other construction activities (e.g., stockpiling of fill material). "Construction site" means the land where any land-disturbing activity is physically located or conducted, including any adjacent land used or preserved in connection with the land-disturbing activity. "Final stabilization" means that one of the following situations has occurred: 1. All soil disturbing activities at the site have been completed and a permanent vegetative cover has been established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieved that is uniform (e.g., evenly distributed), mature enough to survive, and will inhibit erosion. 2. For individual lots in residential construction, final stabilization can occur by either: a. The homebuilder completing final stabilization as specified in subdivision 1 of this definition; or b. The homebuilder establishing temporary soil stabilization, including perimeter controls for an individual lot prior to occupation of the home by the homeowner, and informing the homeowner of the need for, and benefits of, final stabilization. 3. For construction projects on land used for agricultural purposes, final stabilization may be accomplished by returning the disturbed land to its preconstruction agricultural use. Areas disturbed that were not previously used for agricultural activities, such as buffer strips immediately adjacent to surface waters, and areas that are not being returned to their preconstruction agricultural use must meet the final stabilization criteria specified in subdivision 1 or 2 of this definition. "Immediately" means as soon as practicable, but no later than the end of the next business day, following the day when the land-disturbing activities have temporarily or permanently ceased. In the context of this general permit, "immediately" is used to define the deadline for initiating stabilization measures. "Impaired waters" means surface waters identified as impaired on the 2012 § 305(b)/303(d)Water Quality Assessment Integrated Report. "Infeasible" means not technologically possible or not economically practicable and achievable in light of best industry practices. "Initiation of stabilization activities" means: 1. Prepping the soil for vegetative or nonvegetative stabilization; 2. Applying mulch or other nonvegetative product to the exposed area; 3. Seeding or planting the exposed area; 4. Starting any of the above activities on a portion of the area to be stabilized, but not on the entire area; or 5. Finalizing arrangements to have the stabilization product fully installed in compliance with the applicable deadline for completing stabilization. This list is not exhaustive. General Permit No.: VAR10 Page 23 of 23 "Measurable storm event"means a rainfall event producing 0.25 inches of rain or greater over 24 hours. "Stabilized" means land that has been treated to withstand normal exposure to natural forces without incurring erosion damage. Section 12.
