See attached Location Map.

01060 – REGULATORY REQUIREMENTS

All material to be removed shall be disposed of in accordance with Federal and SC State Regulations.

S.C. Department of Health and Environmental Control (DHEC) does not regulate aboveground storage tank (AST) systems. However, it is the responsibility of the contractor to comply with federal and state laws regarding waste disposal. The fuel tanks have been pumped empty, but residual undrained fuels likely remain, and must be disposed of or recycled properly. The hydraulic tank may contain up to 50 gallons of

PCB-containing oil that must be properly disposed of.
