Other Laws that Provide Similar Information

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.  For further information regarding Oil Pollution Prevention Regulation Overview, go to EPA's website at .
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 at .


Access to Public Records

The EPCRA law provides provisions for the public to gain access to facility information and requires municipal, state and federal agencies to retain specific records for a period of time.  For more information regarding the law, visit our webpage that describes the Community Right-to-Know provisions.
