Non-stormwater discharges Discharge Pollutants or Pollutant Location on Site Constituents Issued— 10/2014 Stormwater Pollution Prevention Plan(SWPPP)Albemarle County E. Persons responsible for pollution prevention practices 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 Albemarle County 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. Albemarle County 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. Issued— 10/2014 Stormwater Pollution Prevention Plan(SWPPP) Albemarle County Section 7. Discharges to impaired waters, surface waters within an applicable TMDL wasteload allocation, and exceptional waters. The site discharges to an impaired water, Meadow Creek, located in Albemarle County and the City of Charlottesville. The causes of impairment are Benthic-Macroinvertebrate Bioassessments and Escherichia coli. 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.
