The Environmental Protection Agency is taking direct final action to conform the Emergency Planning and Community Right-to-Know Act hazardous chemical inventory reporting regulations to the Occupational Safety and Health Administration's Hazard Communication Standard amendments of 2012 and 2024. The Emergency Planning and Community Right-to-Know Act and its regulations rely on the Occupational Safety and Health Administration's Hazard Communication Standard for the definition of a hazardous chemical and for the categories of health and physical hazards that must be reported under the hazardous chemical inventory regulations. This action will conform the terminology used and information that must be reported on the hazardous chemical inventory forms to the Hazard Communication Standard amendments. As a result, this action will also improve first responder and community safety, reduce discrepancies and confusion, prevent interpretation burdens on facilities when using (Material) Safety Data Sheets to complete annual hazardous chemical inventory reports, and improve clarity.

DATES: This final rule is effective on January 16, 2026 without further notice, unless the EPA receives adverse comment by December 17, 2025. Published in the Federal Register November 17, 2025, page 51187.

§370.61 How does a person obtain inventory information about a specific facility?

(a) Any person may request Tier II information for a specific facility by writing to the SERC or LEPC.

(1) If the SERC or LEPC has the Tier II information, the SERC or LEPC must provide it to the person making the request.

(2) If the SERC or LEPC does not have the Tier II information, it must request it from the facility owner or operator in either of the following cases:

(i) The person making the request is a state or local official acting in an official capacity.

(ii) The request is for hazardous chemicals in amounts greater than 10,000 pounds stored at the facility at any time during the previous calendar year.

(3) If the SERC or LEPC does not have the Tier II information, it may request it from the facility owner or operator when neither condition in paragraph (a)(2) of this section is met but the person's request includes a general statement of need.

(b) A SERC or LEPC must respond to a request for Tier II information under this section within 45 days of receiving such a request.

§370.62 What information may a state or local official request from a facility?

The LEPC may ask a facility owner or operator to submit an SDS for a hazardous chemical present at the facility. The SERC, LEPC, or fire department with jurisdiction over a facility may ask a facility owner or operator to submit Tier II information. The owner or operator must provide the SDS (unless the owner or operator has already submitted an SDS to the LEPC for that hazardous chemical) or Tier II information within 30 days of receipt of such request.

§370.63 What responsibilities do the SERC and LEPC have to make request information available?

Under this subpart, the SERC or LEPC must make the following information (except for confidential location information discussed in §370.64(b)) available if a person requests it:

(a) All information obtained from an owner or operator in response to a request under this subpart.

(b) Any requested Tier II information or SDS otherwise in possession of the SERC or the LEPC.

§370.64 What information can I claim as trade secret or confidential?

(a) Trade secrets. You may be able to withhold the name of a specific chemical when submitting SDS reporting or inventory reporting information if that chemical name is claimed as a trade secret. The requirements for withholding trade secret information are set forth in EPCRA section 322 and implemented in 40 CFR part 350. If you are withholding the name of a specific chemical as a trade secret in accordance with trade secrecy requirements, you must report the generic class or category that is structurally descriptive of the chemical along with all other required information. You must also submit the withheld information to EPA and must adequately substantiate your claim. A Form for substantiating trade secret claims is available at the Agency website at https://www.epa.gov/epcra.

(b) Confidential location information. You may request that the SERC and LEPC not disclose to the public the location of any specific chemical required to be submitted in Tier II information. If you make such a request, the SERC and LEPC must not disclose the location of the specific chemical. Although you may request that location information (with respect to a specific chemical) be withheld from the public, you may not withhold this information from the SERC, LEPC, and the local fire department. If you use the Tier II Form to report your inventory information, you can choose to report the confidential location information for the specific chemical on the Tier II Confidential Location Form and attach this form to the other Tier II information you are reporting. The Tier II Confidential Location Form is available on the Agency website at https://www.epa.gov/epcra.

§370.65 Must I allow the local fire department to inspect my facility, and must I provide specific location information about hazardous chemicals at my facility?

(a) You must allow the fire department to conduct an on-site inspection of your facility; and

(b) You must provide the fire department with information about the specific locations of hazardous chemicals at your facility.
