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).
