And your business activity fits into one of the regulated industrial sectors, meaning that your industrial activity fits under one or more of the Standard Industrial Classification (SIC) CodesExit the TCEQ or Industrial Activity Codes to be found in "SIC Codes Subject to TPDES Multi-Sector General PermitAdobe Acrobat PDF Document," (Help with PDF.)

Then you will be required to obtain coverage under General Permit TXR050000 Adobe Acrobat PDF Document.

  • If all industrial activities and materials are isolated from rain, snow, snowmelt, and/or runoff by storm resistant shelters, you may be eligible for a conditional no exposure exclusion from permitting requirements.

  • Otherwise, the general permit requires you to obtain coverage, which includes submitting a notice of intent (NOI) form.

If you only have a NAICS code and no SIC code that describes your industrial activity, then it will be necessary to convert the NAICS code to an SIC codeAdobe Acrobat PDF Document to determine if coverage under this permit applies to your facility.

If you don't qualify for coverage under this general permit, you may need to obtain an individual permit for any discharges to water in the state.
