Tier II Chemical Reporting

Tier II Chemical Reports give information about the facility, hazardous chemicals, and emergency contacts. Facilities must keep their most current Tier II Report until they file a new report, which then becomes the most current. Tier II Report information is used by emergency response personnel (fire, police, and Emergency Medical Services) in responding to accidents and other community emergencies and by LEPCs, who use this information for developing community emergency response plans.

In addition to submitting your Tier II reports to the Texas Commission on Environmental Quality (TCEQ) you are also required to submit copies to your local fire department.

Am I Regulated?

Am I Required to Report Stored Chemicals?

Tier II reporting is required for any facility that stores hazardous chemical(s) that meet or exceed chemical thresholds at any one time.
A chemical is hazardous if the facility is required to maintain Material Safety Data Sheets (MSDS) or Safety Data Sheets (SDS) under the Occupational Safety and Health Administration (OSHA) regulations.

Hazardous Chemical Reporting Thresholds

If you store hazardous chemicals in quantities equal to or greater than the reporting threshold for that chemical you must submit a Tier II Report.

Reporting Thresholds

  • Hazardous chemicals: 10,000 lbs.
  • Extremely hazardous substances (EHS): 500 lbs or the threshold planning quantity (TPQ), whichever is less.
  • Retail fuel stations: if tanks are underground and in compliance with underground storage tank federal requirements.
    • Gasoline: 75,000 gallons
    • Diesel Fuel (all grades combined): 100,000 gallons
