Cross-program comparison of federal regulatory thresholds for hazardous chemicals. Each record is one chemical with the thresholds that trigger obligations under different federal programs: CERCLA reportable quantity (release reporting to NRC), EPCRA Section 302 threshold planning quantity (emergency planning), EPCRA Section 313 reporting threshold (TRI), and CAA Section 112(r) threshold quantity (risk management plan). The product is the cross-reference: for benzene, CERCLA RQ is 10 lb, EPCRA TPQ does not apply (not an EHS), but Section 313 threshold is 10 lb — three different programs, three different questions, answered from one page. Answers 'what are all my reporting obligations for [chemical]', 'is [chemical] an extremely hazardous substance under EPCRA', and 'what is the reportable quantity for [chemical]'.
