Business & Industry

In the event of a reportable release:

  • Immediately contact the local Fire Chief where the spill occurred, if within a city’s limits. Afterwards, contact the Fire Marshal, to comply with state reporting requirements.
  • If the release occurred in an unincorporated area of Collin County, contact the Fire Marshal immediately.

Federal and State laws require business and industry operators to perform annual chemical inventories (Tier II Chemical Report) and submit their Tier II Report to the Texas Department of State Health Services (TDSHS), local Fire Chief and the LEPC no later than March 1st of each year.

For more information on Tier II Reporting, Texas Community Right-to-Know and Hazard Communication Acts go to:

Tier II Chemical Reporting Program
Texas Department of State Health Services

The Tier II Chemical Report is a standardized form created by the Environmental Protection Agency (EPA) to rate and identify chemicals and hazardous materials. For the latest information on Tier II Reporting and e-filing, go to:

U.S. Environmental Protection Agency
(click on "search" and enter "Tier II")

Whether or not a company must file this annual report is determined by the type of chemical or material and how much is on-site.

Having this information readily available to the Fire Departments serves two important purposes:

  1. Enhances response time to an incident with the right equipment and personnel.
  2. Immediate knowledge if the public is at risk and advisories are warranted.

In the event of a chemical release (spill, leak, emission, gas cloud), a business or industry must report the incident immediately. Texas Health & Safety Codes state a specific timeline for reporting; failure to do so is a violation of both Federal and State law whether or not first-responders were dispatched to the scene.

Remember, the responding agencies are entitled to recover the costs of securing, containing, and managing the incident.
