Air Emissions and Maintenance Events notifications and reports are required to be submitted via STEERS, the State of Texas Environmental Electronic Reporting System (STEERS).

In the event that STEERS is unavailable due to technical failures or scheduled maintenance, required reporting under 30 Texas Administrative Code (TAC) 101 (e.g., emissions event, opacity event, and maintenance, startup, & shutdown activity) may be completed by emailing the form below to EE@tceq.texas.gov.

STEERS notification and reporting is not required for small businesses that meet the small business definition in Texas Water Code Section 5.135(g)(2). Small businesses shall provide notifications and reporting by any viable means that meet the time frames required by 30 TAC Chapter 101.

If reporting through a mechanism other than STEERS, use the Air Emissions and Maintenance Events Report form:

• Air Emissions and Maintenance Events Report Form
• Air Emissions and Maintenance Events Report Form

Follow these instructions for completing the AEME Report Form

Under certain conditions, Texas allows hot-mix asphalt plants to provide data in lieu of testing when they request permits for new or relocated plants. The testing is otherwise required by state and federal environmental rules for HMAPs.

To help plant operators determine when and how to waive the testing, the TCEQ has prepared the following memorandum written by the TCEQ’s Engineering Services Team and Air Permits Division with input from the Association of General Contractors:  Guidance for Accepting Data in Lieu of Test (DILOT) for New and Relocated Hot Mix Asphalt Plants

The TCEQ receives reports on air emission events under 30 TAC 101.201    and    30 TAC 101.211 :

•  Air Emission Event Report Database.

Users can search the database by different parameters including incident number and county. Search results include, but are not limited to, where the incident was reported, compounds released and quantities, and the event duration. These search results and each incident detail report can be exported to an Excel spreadsheet.

Emissions Events Investigations

When an emissions event occurs, companies must submit an initial notification in the State of Texas Environmental Electronic Reporting System (STEERS) within 24 hours of discovery of the event if a reportable quantity will be exceeded and a final report is due two weeks from the end of the event after the entity has fully evaluated the incident. TCEQ reviews these events against criteria located in the Texas Administrative Code to determine if the event was avoidable and assesses whether or not operators took measures to minimize emissions. 

After receiving a report of an emissions event, TCEQ conducts an initial screening and sends a questionnaire to the reporting entity if appropriate. These questions are based on the Demonstration Criteria in 30 TAC 101.222

Based on the results of an investigation of an incident, the TCEQ may pursue enforcement actions when appropriate against regulated entities which may include the assessment of a penalty.
