This cross-reference document offers a summary of the five major provisions of the Emergency Planning and Community Right-to-Know Act (EPCRA):

  • Sections 302-303 — Emergency planning notification and emergency response plans;
  • Sections 304 — Emergency release notifications;
  • Section 311 — Safety data sheet reporting;
  • Section 312 — Hazardous chemical inventory reporting (also known as Tier II reporting); and
  • Section 313 — Toxics release inventory reporting.

Check the comparison table below for assistance in determining if any of the listed EPCRA requirements may apply. The table is provided as a reference tool. It is not a definitive source of compliance information and is not intended to replace the CFRs. The comparison table is also not comprehensive. Other EPCRA-related reporting requirements, not listed in the table, may exist at the federal, state and/or local levels. Note that the EPCRA trade secret provisions are not summarized here.
