Clean Air Act, Section 112r
The Environment Protection Agency (EPA) requires facilities that produce, handle, process, distribute, or store chemicals to develop a risk management program, prepare a risk management plan (RMP), and submit the RMP to the EPA. You are required to comply with the EPA requirements if you possess a threshold quantity (TQ) of a substance found on the 112r list. Facilities in Oregon are required to identify whether or not they are subject to these requirements on the Oreogn hazardous substance inventory report.
