Changes to 2020 Reporting

We made some improvements to Tier Two Online to help us better align with federal reporting and to improve the overall reporting experience: 

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

Facilities can submit their reports through Tier Two Online. Using our system allows facilities to automatically submit their reports to one of the required agencies, State Emergency Response Commission (SERC).

What are the excluded substances?

  • Any food, food additive, color additive, drug, or cosmetic regulated by the Food and Drug Administration (FDA).

  • Any substance present as a solid in any manufactured item to the extent that exposure to the substance does not occur under normal conditions of use.

  • Any substance used for personal, family, or household purposes, or is present in the same form and concentration as a product packaged for distribution and use by the general public.

  • Any substance used in a research laboratory, hospital, or other medical facility under the direct supervision of a technically qualified individual.

  • Any substance used in routine agricultural operations or fertilizer sold by a retailer to customers.
