EPCRA inventory reports: A case study in federal, state, and local collaboration
Environmental regulations require many facilities to report annual inventories of the hazardous chemicals they use or store. Have you ever considered the impact that this information has beyond regulatory compliance? Reporting facilities, whether they realize it or not, serve an essential role in local emergency response planning.
The Environmental Protection Agency’s (EPA’s) Hazardous Chemical Inventory Reporting program under the Emergency Planning and Community Right-to-Know Act (EPCRA) offers a prime example of how collaboration among the federal, state, local, and facility levels supports safer communities.
What’s EPCRA's inventory reporting program?
The Occupational Safety and Health Administration (OSHA) requires facilities to keep Safety Data Sheets (SDSs) for any hazardous chemical used or stored in the workplace. Facilities that use or store the chemicals on-site at or above certain thresholds at any one time are subject to EPCRA’s Hazardous Chemical Inventory Reporting program. Regulated facilities must report information about the hazardous chemicals to the:
- State Emergency Response Commission (SERC),
- Local Emergency Planning Committee (LEPC), and
- Local fire department.
What’s reported?
EPA’s EPCRA inventory program consists of two reporting requirements under Sections 311 and 312 of EPCRA.
SDSs/lists
Section 311 of EPCRA requires facilities to submit the SDSs for or a list of the hazardous chemicals used or stored on-site at or above the reporting thresholds to the SERC, LEPC, and local fire department.
SDSs usually include comprehensive information, such as:
- The composition of ingredients,
- Physical and health hazard information, and
- First aid and firefighting measures.
If a facility opts to list the chemicals, it must group them by hazard categories and include each chemical’s name and any hazardous components as identified by the SDS. This is generally a one-time submission for each hazardous chemical. However, if a facility submits an SDS for a hazardous chemical and later discovers significant new information about it, the facility has to send an updated SDS to the SERC, LEPC, and local fire department.
Annual inventories
Under Section 312 of EPCRA, facilities must also submit an annual inventory (known as the Tier II inventory report) of the hazardous chemicals used or stored on-site at or above the reporting thresholds to the SERC, LEPC, and local fire department by March 1.
Facilities should check state regulations to confirm Tier II reporting thresholds, as they may be more stringent.
The Tier II inventory report requires information on the covered hazardous chemicals used or stored at the facility during the previous calendar year, including:
- The locations of the chemicals,
- The amounts of the chemicals, and
- The potential hazards of the chemicals.
How do inventories support emergency planning?
Inventory reports provide information that’s vital to effective emergency response planning. Specifically, the inventories tell state and local officials about where hazardous chemical releases may occur and the risks that such releases may pose. Equipped with an accurate view of these hazards, officials can build and maintain effective emergency response plans for their communities.
Each participant in the emergency planning effort plays a distinct role:
- Reporting facilities provide the SERCs, LEPCs, and local fire departments with the information they need to build effective response plans, such as the types of chemicals on-site and their quantities, locations, and possible hazards.
- SERCs designate local emergency planning districts and appoint and supervise LEPCs. They also establish the inventory reporting procedures, review local emergency response plans, and process information requests from the public.
- LEPCs use inventory reports to develop and update emergency response plans that address each community’s unique risks.
- Local fire departments use the inventory reports to understand the potential chemical-related risks they may encounter at specific facilities. By knowing where the chemicals are and the potential hazards they pose, fire departments can improve personnel training and identify the most appropriate ways to respond to chemical emergencies.
Ultimately, reporting facilities aren’t just meeting a compliance requirement; they’re also supporting safer communities.
Key point: EPCRA’s hazardous chemical inventory requirements provide an example of effective collaboration between EPA, state and local officials, and facilities to prepare communities for chemical emergencies.
