Assistance Tools for Construction Stormwater General Permits
The TCEQ has issued the 2018 Construction General Permit (CGP) TXR150000. It became effective March 5, 2018. The 2018 CGP Fact Sheet and Executive Director's Response to Comments are available on the Additional Guidance and Quick Links: Construction Activities web page.
What is the TPDES Construction Stormwater General Permit (TXR150000)?
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.
How can I access a copy of the permit?
You can access the Construction Stormwater General Permit, TXR150000

Do I need to obtain stormwater coverage at my site?
If you discharge stormwater associated with a construction activity, you may need authorization. The need for coverage is based on the area of land disturbed.
- If you disturb less than one acre* - no coverage is needed under this permit.
- If you disturb one or more acres* - coverage is needed 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.
If you need additional help to determine applicability, visit the Stormwater Discharges from Construction Activities: Am I Regulated? webpage.

Surface Water Identification
- Surface Water Quality (Segments) Viewer - Using this interactive map viewer, users can view stream segments and water bodies monitored by TCEQ. Users can also select a particular segment or water body to view additional information such as segment name, ID number, description, and impairment status.
- Texas Integrated Report of Surface Water Quality - To determine if the water body receiving your stormwater discharges is impaired and to identify the pollutant associated with that impairment, you must review the current Index of All Impaired Waters. For permitting purposes, Category 4 and 5 represent the list of impaired waterways. Only a portion of impaired waters are associated with an established TMDL.
- Segments with Total Maximum Daily Loads (TMDL)
