Tier II Inventory Reporting

Facilities that store or handle hazardous chemicals or extremely hazardous chemicals above certain thresholds must submit an annual Tier II inventory report to the State Emergency Response Commission (SERC), Local Emergency Planning Committee (LEPC) and local fire department.

Inventory Reporting

Chemicals that are classified as an Extremely Hazardous Substance are reportable at lower levels. Certain Threshold Planning Quantities (TPQs) are established that are below 55 gallons or 500 pounds. Facilities must notify the LEPC and SERC immediately by letter that an EHS is in their inventory, as well as the name of a facility representative to assist in planning needs.

The facility must provide Material Safety Data Sheets (MSDS) to the SERC and LEPC for each reported chemical in inventory. The MSDS is a chemical- or product-specific form that details the risks associated with the chemical. It describes the chemical, how it will react in fires or with other chemicals, how it affects humans and what first aid measures should be used. The MSDS will also provide protective clothing information and emergency numbers to obtain information from the manufacturers. All of this information is vital for planning and emergency response.

Please read the instructions carefully and avoid common mistakes. Free compliance assistance is available from the LEPC; call the SARA Title III Supervisor at 410-638-4900 or email your request.

Always Report for Prior Year
The reporting year is always the year prior to the current year. Reports due by March 1, 2025 were for inventory during 2024. Example: Reporting period, January 1 through December 31, 2024.

Tier II Chemical Reporting Forms

Don't Over Report
Report only those inventory items that were held at any one time over the required reporting amount (10,000 pounds non-EHS, or 500 pounds or the required threshold planning quantity of a, EHS). If you are not sure, contact the LEPC, 410-638-4900. Use the proper codes and double check the coded amounts. Reporting is in pounds so all correspondence must match.

Original Signature Required
All reports to all agencies must have an original signature of the facility representative. No stamps or copies. All signatures should be in blue ink to assist in the determination that the signature is original.

No Post Office Listing
The facility address cannot be a post office box. You must provide a real street address for the location. In the owner/operator identification, the mailing address may be a post office box.
