Tier Two Reporting Requirements

Under EPCRA Section 312, any facility in Washington State that stores over a certain amount (reporting threshold) of a hazardous chemical must report this by March 1 each year to:

  • The Washington State Emergency Response Commission (SERC)
  • Their Local Emergency Planning Committee (LEPC)
  • Their local fire department

Reporting thresholds for hazardous substances are 10,000 pounds or more at any one time. The thresholds for extremely hazardous substances vary, depending on the chemical.

Tier Two data includes the number of facilities storing extremely hazardous substances (EHSs). The 360 chemical compounds classified as EHS are designated by the U.S. Environmental Protection Agency (EPA). Tier Two reports help tell us what chemicals are stored in our communities. LEPCs and local fire departments use the information for emergency preparedness, planning, and response to incidents at or near reporting facilities.

The information required on the Tier Two report includes facility identification, chemical name, physical and health hazards, actual pounds for maximum and average amounts stored, and storage and location descriptions. Ecology maintains this information to track facility compliance and to share with the public, LEPCs, fire departments, and other government agencies upon request.
