Phase II cities are also required to obtain stormwater discharge permit coverage for municipal facilities with specific regulated industrial stormwater discharges. The Texas Commission on Environmental Quality (TCEQ) was delegated authority by the EPA to administer the NPDES program in the State of Texas (TPDES).
The City of Killeen, as a regulated Phase II MS4 operator, is required to obtain stormwater discharge coverage under the TPDES pro...
