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 "I 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 disposed of in a manner 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 storm 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 SWNVBMP facility. Authorized Non-Stormwater Discharges The following table (Table 4) displays non-stormwater discharges from construction activities that are authorized by this general permit when discharged in compliance with the permit: Table 4.
