An individual who holds a valid license from TCEQ to install or repair an OSSF is known as a?

An individual with a valid license from the Texas Commission on Environmental Quality (TCEQ) to install or repair an On-Site Sewage Facility (OSSF) is referred to as an Installer. This designation signifies that the individual has met the necessary requirements and received the appropriate training and credentials to perform installation and repair work on OSSFs, which play a critical role in managing sewage and wastewater in areas not served by centralized sewer systems.

Other terms mentioned in the question refer to different roles within the OSSF framework. An apprentice, for instance, is typically someone who is still in training and may not yet hold a license to perform independent work on OSSFs. An authorized agent usually acts on behalf of the regulatory body to enforce compliance or oversee the OSSF systems, rather than directly installing or repairing them. A maintenance provider focuses on the upkeep and service of existing OSSF systems but may not have the licensing specifically for installation or repair. Thus, the title of Installer specifically denotes the licensed professional capable of engaging in the installation and repair of OSSFs, making it the correct designation for the scenario described.
