Any Fish Kills must be reported, Reporting information regarding specific substances can be found below. Potential Pollution Generating Prevention/Response AcfiWdes: QuickReference Chart Fuels, Hydraulic Vehicle refueling and maintenance operations will be conducted in a dedicated Oils and Vehicle location away from surface waters. Secondary containment (berms), readily Maintenance available spill kits and cover will be provided where appropriate. For additional information, see the Fuels and Oils subsection below. Soaps, Solvents, Chemicals will be safely stored in sealed containers when not in use. Clean-up and Detergents & disposal will be done in a manner to prevent contact with stormwater, utilizing Wash Water cover, tarps, buckets, and proper disposal techniques. For additional information, see the Hazardous and Toxic Chemicals subsection below. Construction products and materials will be stored in a safe location and handled in a manner consistent with the pollution prevention plan and manufacturer's Hazardous recommendations. Likely utilized items on site include asphalt sealants, copper Materials Construction flashing, roofing materials, adhesives, concrete admixtures, pesticides, herbicides, products, materials, insecticides, fertilizers, and landscape materials. Construction and domestic wastes and wastes such as packaging materials, scrap construction materials, masonry products, timber, pipe and electrical cuttings, plastics, Styrofoam, concrete, and other trash or building materials will be disposed of properly. For additional information, see the Hazardous and Toxic Chemicals subsection below. Fertilizers will be applied per manufacturer's recommendations and not during Fertilizers rainfall events. For additional information, see the Hazardous and Toxic Chemicals subsection below. On site portable lavatories must be located away from surface waters and storm Sanitary Wastes drains. Any spills must be cleaned according to federal, state and local regulations. For additional information, see the Sanitary Waste subsection below. Wash Water without Wash water will be directed to sediment basins or traps, using filtration devices Non-Stormwater Soaps such as filter bags or sand filters or similarly effective controls. Discharges Site Excavation Must pass through a sediment trapping device and be released onto a stabilized (Examples listed in Dewatering surface. Conveyance channels must be stabilized. Table 4 below) Utility Flushing Energy from clean water releases must be appropriately dissipated in a stabilized area. For additional information, see the Water Testing subsection below. Concrete wash water will be directed into a leak -proof settling basin or container. The container or basin shall be designed so that no overflows can occur due to Concrete Waste & inadequate sizing or precipitation. Hardened concrete wastes shall be removed and Wash Water manner disposed of in a miner consistent with the handling of other construction wastes. Liquid concrete wastes shall be removed and disposed of in a manner consistent with the handling of other construction wash waters and shall not be discharged to Managing Waste surface waters. For additional information, see the Concrete subsection below. All solid waste and debris must be deposited in dumpsters and kept out of surface waters. Exposure of waste materials to precipitation shall be minimized by closing Solid Waste or covering waste containers during precipitation events and at the end of the business day or by implementing other similarly effective practices. Minimization of exposure is not required in cases where the exposure to precipitation will not result in a discharge of pollutants. Other Spills and Leaks Oil, chemical or other hazardous substance spills and leaks that exceed the reportable threshold will be reported to the DEQ in accordance with Part III G of the Permit as soon as the discharge is discovered, and in no case later than within 24 hours. A reportable quantity of oil is defined by the EPA as a discharge to surface waters that causes a sheen, discoloration, and/or an emulsion. A written report of the unauthorized discharge shall be submitted to the DEQ and VSMP authority within five days of the discovery of the discharge and include the information listed below: • Name, address, and telephone number of the person reporting and the responsible party • Specific location of the incident • Date and time the incident occurred or was discovered • Name of the chemical/material released • Source and cause of the release • Total quantity discharged • Medium into which the substance was discharged • Amount spilled into water • Weather conditions • Name of the carrier or vessel, the railcar/truck number, or other identifying information • Number and type of injuries or fatalities • Whether an evacuation has occurred • Estimation of the dollar amount of property damage • Description of current and future cleanup actions • Other agencies notified or about to be notified Reports will be made to the following: DEQ Valley Regional Office Phone: (540) 574-7800 Fax: (540) 574-7878 For reports outside normal working hours, leave a message. Virginia Department of Emergency Management Emergency Operations Center (EOC) Phone: 1-(800) 468-8892 Materials and equipment necessary for oil or chemical spill/ leak cleanup will be kept in the temporary material storage trailer onsite. Equipment will include, but not be limited to, brooms, dust pans, mops, rags, gloves, goggles, universal absorbents, sand, saw dust, and plastic and metal trash containers. All oil or other chemical spills/ leaks will be stopped, contained, and cleaned up immediately upon discovery. Those large enough to reach the stone sewers will be reported to the National Response Center at 1-800-424-8802. In the event of a hazardous spill contact: 9-1-1 Fuels and Oils The State Code of Virginia §62.1-44.34:19, states that discharges that may be reasonably expected to enter state waters, lands or storm drains must be reported. In the event of a spill, it will be stopped, contained, and cleaned up immediately and the material, including any contaminated soil, will be disposed of according to all federal, state, and local regulations. Any on -site storage tanks will have a means of secondary containment. All vehicles on site will be monitored for leaks and receive regular preventive maintenance to reduce the chance of leakage. Petroleum products will be stored in labeled, sealed containers. Spill kits will be included with all fueling sources and maintenance activities Hazardous and Toxic Chemicals Spills of hazardous or toxic chemicals that exceed the reportable quantity threshold must be reported, as previously stated. The EPA lists reportable quantity thresholds for each chemical under 40 CFR Part 110, 40 CFR part 117, or 40 CFR part 302. All paint containers and curing compounds will be tightly sealed and stored when not required for use. Excess paint will not be discharged to the storm sewers but will be properly disposed according to the manufacturer's instructions. Spray guns will be cleaned on a removable tarp. Chemicals used on -site are kept in small quantities and stored in closed containers undercover and kept out of direct contact with stormwater. As with fuels and oils, any inadvertent spills will be cleaned up immediately and disposed of according to federal, state, and local regulations. Fertilizers will be applied only in the minimum amounts recommended by the manufacturer. Fertilizers will be worked into the soil to limit exposure to stormwater. Fertilizers will be stored under cover and partially used bags will be transferred to a sealable bin to avoid spills. Sanitary Waste Portable lavatories are located on -site and are serviced on a regular basis by a contractor. They will be located in upland areas away from direct contact with surface waters. Any spills occurring during servicing will be cleaned up immediately, including any contaminated soils, and disposed of according to all federal, state, and local regulations. Concrete Concrete trucks will not be allowed to wash out or discharge surplus concrete or drum wash water on the site, except in a specially designated concrete washout area which contains all wash water resulting from washout activities. Form release oil used for decorative stonework will be applied over a pallet covered with an absorbent material to collect excess fluid. The absorbent material will be replaced and disposed of properly when saturated. Water Testing When testing/cleaning of water supply lines, the discharge from the tested pipe will be collected and conveyed to a completed stormwater pipe system for ultimate discharge into a sedimentation basin or SWM/BMP facility.

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.
