Course Description

The OSSF – Designated Representative course not only prepares local government personnel to enforce TCEQ OSSF rules and regulations in coordination with the commission, participants also receive information specific to the proper design, construction, and operation of multiple on-site sewage disposal systems along with best practices linked to the proper response to complaint calls. Once students successfully complete the course, a proctored TCEQ OSSF Designated Representative licensing examination will be administered.


There are no prerequisites for this course.

Course Completion Requirements

TCEQ Licensing Requirements

Once registered, participants are required to submit a licensing application using the TCEQ eApplication site along with a copy of the TEEX course registration confirmation. TCEQ processing time for the application is approximately 2 to 4 weeks. Once received, TCEQ will provide the student with a conditional approval letter permitting the student to sit for the licensing exam administered at the conclusion of the class. A copy of the letter must be uploaded to the TEEX Student Portal for Customer Care review at least 14 days prior to the beginning of the class.

Attendance Requirements

Class attendance is an essential part of the education process and participants in TEEX courses are expected to attend all class sessions and field exercises. This course requires participants to attend a minimum of 100% of the class hours as a component of successful course completion. During the course, your instructor will review any additional attendance requirements, for example a field exercise that cannot be missed.

The practice scenarios working within a group of my collegues and peers was most helpful. It was tabletops with the why and all parties, players, and stakeholders in the same room.
