Tier II Reporting

Under the federal Emergency Planning and Community Right to Know Act (EPCRA), facilities that manufacture, use, or store hazardous chemicals above certain amounts at any given time during the calendar year are required to submit reports on their chemical inventories.

A Tier II Report is an annual inventory of stored chemicals that meet or exceed certain thresholds required under Section 312 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA). The purpose is to provide state and local officials, and the public with specific information on potential hazards.
