Tier II Chemical Inventory Reporting Requirements


What is a Tier II Chemical Inventory Report?

A Tier II Chemical Inventory Report is a report that facilities are required to submit to their State Emergency Response Commission (SERC), Local Emergency Planning Committee (LEPC), and local fire department annually. The report provides information about the hazardous chemicals that are stored or handled at the facility.


What regulation governs Tier II Chemical Inventory Reporting?

Tier II Chemical Inventory Reporting is governed by Section 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA). EPCRA is a federal law that requires facilities to disclose information about their hazardous chemicals to the public.


What types of facilities may be required to report?

Any facility that stores or handles hazardous chemicals in quantities equal to or greater than the threshold planning quantity (TPQ) for any one chemical is required to submit a Tier II Chemical Inventory Report. A few examples include:


-Field service facilities storing lubrication oils, coolants, gasoline, diesel, degreasers, or similar. -Tank batteries. -Compressor stations. -Retail and distribution facilities storing chemicals.


For specific information on chemical quantities, see https://www.epa.gov/epcra/consolidated-list-lists.
