A. Discharges covered under this section. The requirements listed under this section apply to stormwater discharges associated with industrial activity from facilities engaged in dismantling or wrecking used motor vehicles for parts recycling or resale, and for scrap (SIC Code 5015).

B. Stormwater controls. In addition to the requirements of Part III, the SWPPP shall include, at a minimum, the following items:

1. Spill and leak prevention procedures. All vehicles that are intended to be dismantled shall be properly drained of all fluids before being dismantled or crushed, or other equivalent means shall be taken to prevent leaks or spills of fluids upon arrival at the site, or as soon thereafter as feasible. All drained fluids shall be managed to minimize leaks or spills.

2. Inspections. Upon arrival at the site, or as soon thereafter as feasible, vehicles shall be inspected for leaks. Any equipment containing oily parts, hydraulic fluids, any other types of fluids, or mercury switches shall be inspected at least quarterly (four times per year) for signs of leaks. All vessels, containers, or tanks and areas where hazardous materials and general automotive fluids are stored, including mercury switches, brake fluid, transmission fluid, radiator water, and antifreeze, shall be inspected at least quarterly for leaks. Quarterly inspection records shall be maintained with the SWPPP.

3. Employee training. Employee training shall, at a minimum, address the following areas when applicable to a facility: proper handling (collection, storage, and disposal) of oil, used mineral spirits, antifreeze, mercury switches, and solvents.

4. Management of runoff. The permittee shall implement control measures to divert, infiltrate, reuse, contain, or otherwise reduce stormwater runoff to minimize pollutants in discharges from the facility. The following management practices shall be used to prevent or reduce the discharge of pollutants to surface waters:

a. Berms or drainage ditches on the property line used to help prevent run-on from neighboring properties;

b. Berms for uncovered outdoor storage of oily parts and engine blocks;

c. Aboveground liquid storage;

d. The installation of detention ponds, filtering devices, or oil/water separators; and

e. Another control measure used to prevent or reduce the discharge of pollutants to surface waters.

C. Benchmark monitoring and reporting requirements. Automobile salvage yards are required to monitor their stormwater discharges for the pollutants of concern listed in Table 200.
