TCEQ Occupational Licensing Response to COVID-19 

With the onset of COVID-19 (coronavirus) and the Governor’s Proclamation of a state of disaster in Texas, TCEQ is extending the expiration dates of all occupational licenses expiring March through August of 2020 by 30 days. All licenses expiring after August 31, 2020 are expected to comply within the original 3-year renewal cycle. TCEQ is aware that occupational license holders may be having difficulty locating in-person continuing education classes for renewal of their licenses. All license holders are encouraged to seek online training opportunities, when possible.

BPAT license holders whose licenses expire March 2020 through March 2021 are still required to obtain 24 continuing education hours through online courses; however, the TCEQ is temporarily waiving the requirement that eight (8) of the CE hours must be hands-on, practical skills training in order to renew their license. This information and future updates are available at Occupational Licensing Responses to COVID-19 (coronavirus).

Bac-Flo Unlimited Courses 

Our courses have been modified for six foot spacing with students having his or her own testing equipment and supplies. Additional ventilation, face covering requirement, an abundance of sanitation measures throughout classroom and lab testing area, along with temperature checks have been implemented for the safety of our students. Entire course is conducted in an outdoor, pavilion type setting. 


In the interest of safety, paper exams have been cancelled. TCEQ management is reviewing the situation regularly and plans to restart paper exams once it is determined safe to do so. However, some CBT Centers are open or planning to reopen soon for limited testing under additional safety guidelines. Please contact your local CBT center to find out their operational status. TCEQ will continue to extend the validity of new applications until testing is more widely and consistently available.

Approved applicants who have not taken their allotted four exam attempts will not be required to reapply and pay the application fee again.

If your approved application expired in March - December 2020 and you have not attempted the exam four times with that application, once you have registered to take an exam at a CBT center, TCEQ will extend your application expiration date. You must contact TCEQ at licenses@tceq.texas.gov once you have scheduled your exam at an approved CBT center.

Be sure to include the following in your email: full name, customer number & the date you are schedule to test. We will update your application expiration date. If you do not contact us after scheduling your exam, your expired application will cause the CBT system to prevent you from taking the exam at a CBT center.

The application expiration date extension, to be granted under this policy, would be equivalent to the period of time TCEQ paper exams were unavailable due to the pandemic.

This policy will remain in place until exams are more widely and consistently available.
