UPDATERenewal of the Construction General Permit

TPDES Construction Stormwater General Permit

Stormwater runoff from construction activities can have a significant impact on water quality. As stormwater flows over a construction site, it picks up pollutants like sediment, debris, and chemicals, and deposits them in creeks, streams, rivers, lakes, etc. The construction stormwater general permit is one way to authorize this discharge.

2023 Construction Stormwater General permit TXR150000 

Applicability

Stormwater discharges associated with a construction activity may need authorization depending on the area of land disturbed.

  • If you disturb less than one acre* - you don’t need coverage under this permit.
  • If you disturb one or more acres* - you do need coverage under this permit.

*If your construction activity is part of a larger Common Plan of Development, you must consider the total area of acres disturbed - even if the development is completed in phases.

Stormwater Pollution Prevention Plan

A SWP3 outlines your plans, or best management practices, to control contaminants that may be discharged in stormwater runoff. Update your SWP3 as conditions change at your construction site. See our CGP SWP3 Template (RG-639) for guidance. ( Word or PDF)

Compliance Resources

General Compliance Overview

Surface Water Identification

  • Surface Water Quality Segments Viewer – This interactive map shows stream segments and water bodies monitored by TCEQ. You can select a segment or water body for additional information such as segment name, ID number, description, and impairment status.
  • Texas Integrated Report of Surface Water Quality – Check if your stormwater discharge enters an impaired water body using the latest Index of All Impaired Waters (Categories 4 and 5). If you discharge a pollutant(s) associated with an impairment, your SWP3 must incorporate the conditions and requirements associated with the total maximum daily load (TMDL) for that impaired water body. Only a portion of impaired waters are associated with an established TMDL.
  • Completed Total Maximum Daily Loads and Implementation Plans – Check if a TMDL exists for any of the water bodies that receive stormwater runoff from your construction site.  

Edwards Aquifer Requirements

Construction taking place over the Recharge, Contributing, or Transition Zones of the Edwards Aquifer may have additional requirements.

Forms

Applicants must submit NOI, LREW, Notice of Termination, and Notice of Change forms online using the e-permitting system (STEERS) or obtain an electronic reporting waiver. A separate waiver form is required for each permit and may be obtained by contacting the Stormwater Program at 512-239-3700.
