Assistance Tools for Construction Stormwater General Permits

UPDATERenewal of the Construction General Permit 

TCEQ renewed the 2023 CGP effective March 5, 2023. You can find the 2023 CGP Fact Sheet and Executive Director's Response to Comments on the Additional Guidance and Quick Links: Construction Activities webpage.

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.

Visit the Stormwater Discharges from Construction Activities: Am I Regulated? webpage for more information.

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

• Stormwater General Permit for Construction Activities – Requirements and options for the discharge of stormwater from construction activities, including links to other pages relevant to this permit.

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.
• Segments with TMDLs – 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.

• Edwards Aquifer Protection Program
• What Plans You Might Need - This webpage will help you determine the type of plan and forms you need to develop your Edwards Aquifer protection plan. 
• Edwards Aquifer Brochure (RG-011)
• Edwards Aquifer Map Viewer
