The Emergency Planning and Community Right-to-Know Act (EPCRA, 1986) implemented two chemical reporting programs:
- The Toxic Release Inventory (TRI)
- The on-site chemical storage inventory (Tier 2)
EPCRA uses several standards defined by the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard (HCS) to establish reporting thresholds under the TRI and Tier 2 programs.
The TRI is a Federal Inventory that tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. U.S. facilities in different industry sectors must report annually to EPA how much of each chemical is released to the environment and/or managed through recycling, energy recovery, and treatment. (A “release” of a chemical means that it is emitted to the air or water, or placed in some type of land disposal.) The information submitted by facilities is compiled in the TRI. The TRI helps support informed decision-making by companies, government agencies, non-governmental organizations, and the public. To learn more, see the EPA Toxics Release Inventory Program.
The HCS defines the term “hazardous chemical” and requires an OSHA facility to have a Material Safety Data Sheet (SDS) available for review by all employees for each hazardous chemical stored at the facility. EPCRA uses these parameters as thresholds that require a facility to submit annual inventory information (Tier 2 reports) for each hazardous chemical that exceeds a storage threshold quantity as defined in EPCRA Section 312 regulations.
Although there are not Tier 2-specific permits, the topic is discussed in this Permit Wizard because facilities must submit these reports to the State Emergency Response Commission (SERC) or Tribal Emergency Response Commission (TERC), Local Emergency Planning Committee (LEPC) or Tribal Emergency Planning Committee (TEPC), and local fire department. Guidance for submitting Tier 2 reports is outlined in the Tier 2 Chemical Inventory Program.
For more information on the TRI and Tier 2 programs, you can review the EPA EPCRA Fact Sheets.
