District of Columbia
Tier II reporting is required under the federal Emergency Planning and Community Right-to-Know Act (EPCRA). Facilities that store hazardous chemicals above reporting thresholds must submit annual inventory information so emergency responders, state officials, and local authorities can prepare for incidents. Because DC is a single jurisdiction, HSEMA functions as both the SERC and the LEPC — there is no separate county-level LEPC to file with.

Overview
Tier II reporting is required under the federal Emergency Planning and Community Right-to-Know Act (EPCRA). Facilities that store hazardous chemicals above reporting thresholds must submit annual inventory information so emergency responders, state officials, and local authorities can prepare for incidents. Because DC is a single jurisdiction, HSEMA functions as both the SERC and the LEPC — there is no separate county-level LEPC to file with.
Reporting thresholds
- 10,000 lbhazardous chemicalStored at any one time: use the maximum quantity present at any point during the reporting year, not an average.
- 500 lbor TPQ, lowerFor an Extremely Hazardous Substance (EHS), report at this amount or its Threshold Planning Quantity, whichever is lower.
Threshold note: HSEMA serves as both SERC and LEPC because DC is a single jurisdiction.
Basic filing steps
- 1Gather facility identification details and current hazardous chemical inventory.
- 2Access the HSEMA Online Tier II Manager (Hazconnect).
- 3Enter or update facility, contact, and chemical information.
- 4Review submission for completeness and certify accuracy.
- 5Submit the report to HSEMA and complete separate fire department notification.
Common compliance risks

- Incorrect quantity calculations or incorrect hazard classification.
- Assuming HSEMA's dual SERC/LEPC role removes separate fire department submission requirements.
- Failing to document proof of submission.
