History of TCEQ and Its Predecessor Agencies

The history of natural resource protection by the State of Texas is one of gradual evolution from protecting the right of access to natural resources (principally surface water) to a broader role in protecting public health and conserving natural resources for future generations of Texans.

Natural resource programs were established in Texas at the turn of the 20th century, motivated initially by concerns over the management of water resources and water rights. In parallel with developments in the rest of the nation, and at the federal level, state natural-resource efforts broadened at mid-century to include the protection of air and water resources, and later to the regulation of generating hazardous and non-hazardous waste.

During the 1990s, the Texas Legislature moved to make natural-resource protection more efficient by consolidating programs. This trend culminated in the creation of the Texas Natural Resource Conservation Commission in the fall of 1993 as a comprehensive environmental protection agency.

Sunset legislation passed by the Texas Legislature in 2001 continued the agency and changed its name to the Texas Commission on Environmental Quality. In 2011, sunset legislation continued TCEQ through 2023, and in 2023, sunset legislation continued TCEQ through 2035.

  • On September 1, the Texas Natural Resource Conservation Commission formally changes its name and begins doing business as the Texas Commission on Environmental Quality.

    The name change was required by our Sunset legislation, House Bill 2912. The Texas Legislature felt that the new name is shorter and gives people a better sense of the agency’s purpose. Plus, it’s more consistent with what other states call their environmental agencies.

    The agency name change did not affect any previous permits, registrations, or any other paperwork or transactions between the public and the TNRCC earlier than Sept. 1, 2002. It also did not affect any signs or other postings required of businesses by this agency. All the powers, duties, rights, and obligations of the Texas Natural Resource Conservation Commission are the powers, duties, rights and obligations of the Texas Commission on Environmental Quality. (See the official notice in the Texas Register of March 30, 2002.)
