Stormwater Management Program
The Federal Stormwater Phase II Final Rule requires all Municipal Separate Storm Sewer Systems (MS4’s), which includes Flower Mound, to apply for a Nation Pollutant Discharge Elimination System (NPDES) permit to address stormwater runoff, by means of a stormwater management program. Operators of regulated MS4s are required to design their stormwater program to reduce the discharge of pollutants to the “maximum extent practicable’, to protect water quality; and to satisfy the appropriate water quality requirements of the Clean Water Act. The Phase II Rule defines a small MS4 stormwater management program as a program comprising six elements that, when implemented in concert, are expected to result in significant reductions of pollutants discharged into receiving water bodies. The six elements include:
