Oil and Gas Activities

While the regulation of oil and gas activities in Texas falls primarily under the jurisdiction of the Railroad Commission of Texas (RRC), the Texas Commission on Environmental Quality (TCEQ) plays an important role in the areas of air quality, surface water management, water quality, and waste management.

Compliance Alerts

  • Oil and Gas Wastewater Discharge Permits – House Bill (HB) 2771 requires TCEQ to submit a request to EPA for the authority to regulate wastewater discharges into water in the state from crude oil and natural gas exploration, development, or production. When EPA grants regulatory authority to TCEQ, the bill will transfer state permitting authority for these discharges from the Railroad Commission of Texas to TCEQ. In anticipation of receiving regulatory authority from EPA, TCEQ is hosting a free online workshop to familiarize regulated entities with our online permitting and reporting tools.

  • Sour Gas Handling Compliance – Permitting options and guidance relating to oil and gas sites that handle or produce ‘sour’ gas.

  • NEWTexas NPDES Oil and Gas Permittees Report DMR Data in NetDMR-Texas TCEQ Instance
    On January 15, 2021, the TCEQ became the authority responsible for NPDES Oil and Gas permits. This change impacts the way O&G permittees submit Discharge Monitoring Report (DMR) data.

    Beginning June 24, 2021, O&G permittees will no longer use the EPA Region 6 NetDMR instance: NDMR-R6: NetDMR: EPA Region 6 – AR-GM-LA-NM-OK-TX. Instead permittees must begin reporting to the Texas TCEQ instance: NDMR-TX: NetDMR: Texas TCEQ. Use the TCEQ’s step-by-step guide to add the NetDMR - Texas TCEQ Instance to your Central Data Exchange (CDX) account.

    You can reach the TCEQ’s NetDMR Helpline at or call us at 512-239-eDMR (3367) if you have questions regarding the Texas TCEQ instance.
