• Increase awareness and emphasize importance of reporting significant releases and up-to-date, accurate inventories.
• Obtain and provide the general public with information mandated under EPCRA and SARA Title III; support the adopted County Emergency Response Plan; utilize Tier II information to enhance the performance of first responders and supporting agencies within Collin County and the region.

What Chemicals Must be Reported

Hazardous Materials subject to regulation include:

• Extremely Hazardous Substances
• Hazardous Substances
• Hazardous Chemicals over 10,000 lbs.
• Toxic Chemicals
• EPA Response Management Plan List of Toxics & Flammables

It is the responsibility of the business/industry to determine what chemicals and corresponding Threshold Planning Quantities (TPQ) are to be reported. Please refer to Material Safety Data Sheets (MSDS) accompanying materials.

For Frequently Asked Questions and lists, refer to the TCEQ website or the EPA.

Failure to report can result in a Federal, state and local civil violation if:

• An incident occurs and no Tier II Report is on file with either of the above;
• A spill or release of a reportable nature is not reported within the specified time-frame as required by law, whether or not first responders were dispatched.

Additionally, responding agencies are entitled by law to recover the costs of securing, containing, and managing an incident.
