The Texas Commission on Environmental Quality (TCEQ) established the Texas Pollutant Discharge Elimination System (TPDES) Phase II General Permit No. TXR040000; issued December 2013 to ensure that Texas water bodies are not polluted deliberately. This permit sets the requirements and conditions for stormwater discharges from a small municipal separate storm sewer system (MS4) into surface water in the state.
The City adopted a Stormwater Discharge Ordinance on February 11, 2020 to comply with the TPDES General Permit No. TXR040000 Permit. As part of the permit, the development of a Stormwater Management Program (SWMP) (PDF) was also required to protect stormwater quality to the highest level feasible.
The permit establishes seven Minimum Control Measures (MCM) of which five are currently applicable to City of Celina. The following are the applicable MCMs:
Public Education, Outreach and Involvement
Illicit Discharge Detection and Elimination (IDDE)
Construction Site Stormwater Runoff
Post Construction Stormwater Management in New Development and Redevelopment
Pollution Prevention and Good Housekeeping for Municipal Operations
