HOTUPDATE2022 Amendment to the Construction General Permit (CGP) TXR150000

The TCEQ has issued the amendment without renewal to the 2018 CGP with an effective date of January 28, 2022. This amendment expands the applicability of the CGP for non-exempt oil and gas construction activities in response to the recent transfer of state and federal regulatory authorityAdobe Acrobat PDF Document to TCEQ for discharges associated with oil and gas exploration, production, processing, or treatment operations, or transmission facilities. This amendment without renewal does not impact existing permittees with an authorization under the TCEQ-issued 2018 CGP.

Existing operators regulated under the EPA-issued CGP for Texas (TXR10F000): You have 90-days from January 28, 2022, to obtain coverage under the TCEQ-issued amended CGP by submitting a Notice of Intent (NOI) or Low Rainfall Erosivity Waiver (LREW), as applicable, using TCEQ’s online e-permitting system STEERS/ePermits.

Existing operators regulated under the TCEQ-issued CGP (TXR150000): This amendment to the CGP does not affect your existing permit coverage, therefore no additional action is required regarding any authorizations under the amended CGP. If you were covered under the 2018 CGP, you will still be covered under the amended permit.

Stormwater Pollution Prevention Plan (SWP3)

The CGP requires construction site operators to develop a Stormwater Pollution Prevention Plan (SWP3) prior to commencing construction.

An SWP3 is a document that outlines construction plans and best management practices (BMPs) to control pollutants that may be discharged in stormwater runoff. Small Business and Local Government Assistance (SBLGA) has developed templates to help you develop your SWP3.
