Related Laws
The Oil Pollution Act (OPA) of 1990 includes national planning and preparedness provisions for oil spills that are similar to EPCRA provisions for EHSs. Plans are developed at the local, state and federal levels. The OPA plans offer an opportunity for LEPCs to coordinate their plans with area and facility oil spill plans covering the same geographical area.
The 1990 Clean Air Act Amendments required the EPA and OSHA to issue regulations for chemical accident prevention. Facilities that have certain chemical above specified threshold quantities are required to develop a risk management program to identify and evaluate hazards and manage those hazards safely. Facilities subject to EPA's risk management program rules must submit a risk management plan (RMP) summarizing its program. For further information regarding RMP guidance, go to EPA's website: Clean Air Act, Section 112 (r) - Risk Management Program rule.
