Tier II Reporting & Community Right-to-Know
Tier II Reporting
The Emergency Planning and Community Right-to-Know Act (EPCRA) was established to help communities plan for potential chemical emergencies. By requiring industry to report on the use, storage, and release of hazardous substances, state governments and local communities can use this information to prepare for potential risks. Facilities containing chemicals at or above EPA thresholds must submit a chemical inventory (a Tier II report) to the state on an annual basis. This information must also be made available to the public.
In Oklahoma, the DEQ acts as the state’s central repository for Tier II information. Facilities electronically submit Tier II reports each year, and DEQ distributes them to Local Emergency Planning Committees (LEPCs) and fire departments statewide. Tier II reports are used by LEPCs to develop response plans for hazardous material spills or natural disasters. Fire departments use Tier II reports to pre-plan incident response; as well as prepare personnel for any chemicals or hazards that may be present when responding to emergencies.
