Tier Two reporting requirements

Under the Emergency Planning and Community Right-to-Know Act (EPCRA) Section 312, any facility in Washington that stores over a certain amount (reporting threshold) of a hazardous chemical must submit a Tier Two report by March 1 each year. 

Send this report to:

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

What do I need to report?

You must report the following for Tier Two:

  • Facility identification
  • Chemical name(s)
  • Physical and health hazards
  • Actual pounds for maximum
  • Average amounts stored
  • Storage type
  • Location descriptions

Reporting threshold

The threshold levels for reporting chemicals stored onsite at any one time are:

  • 10,000 pounds for hazardous substances.
  • 500 pounds or the threshold planning quantity, whichever is less for an Extremely Hazardous Substance (EHS).

Refer to your SDS/MSDS to determine if your product contains an EHS ingredient.

To determine the threshold planning quantity, refer to the Environmental Protection Agency's Consolidated List of Lists. All EHSs are listed, but not all reportable products are included.

Exemptions

An exemption should be filed if your business, during the previous calendar year, has:

  • Closed.
