Assistance Tools for Municipal Separate Storm Sewer Systems (MS4s)
Municipal separate storm sewer systems (MS4s) consist of a conveyance or system of conveyances, including roads with drainage systems, streets, catch basins, curbs, gutters, ditches, human-made channels, or storm drains. The following resources are provided to assist the regulated community in meeting permit requirements.
Tools
- Issued TXR040000 Permit for Phase II (Small) MS4s
Municipal Separate Storm Sewer System Model Ordinance- Atlas of Texas Surface Waters
- 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.
- 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.
