The Tier II reporting deadline is approaching quickly – March 1, 2023 – and many facilities are not even aware they are required to report. Is your facility ready?

What is Tier II reporting?

After a series of hazardous chemical releases which caused human and environmental harm, the Emergency Planning and Community Right-to-Know Act (EPCRA) was created to facilitate more effective and safe responses to chemical accidents and inform citizens of the chemicals used in their community.

Tier II reporting is required for any facility that stored hazardous chemicals that met or exceeded thresholds at any one time during the prior calendar year. Any chemical with a Safety Data Sheet (SDS) is considered hazardous.

Facilities subject to Tier II must submit an annual emergency and hazardous inventory form by March 1st of each year to their State Emergency Response Commission (SERC), Local Emergency Planning Committee (LEPC), and the fire department with jurisdiction over the facility.

What are the Tier II Thresholds for reporting?

  • Hazardous chemicals: 10,000 pounds 
  • Extremely Hazardous Substance (EHS): 500 pounds or the threshold planning quantity (TPQ), whichever is less. Common EHSs include ammonia, chlorine, chloroform, formaldehyde, hydrogen peroxide, nitric acid, and sulfuric acid.

How do I report?

Each state can choose from the following reporting software options: Tier II Manager, E-Plan, Tier2 Submit, or their own software tool. You can visit the USEPA website for your state's requirements and procedures. The link below will direct you to the Tier II reporting procedures and requirements for your state.
