What is the minimum acreage for sites to comply with numeric effluent limitations as of February 2014?

The minimum acreage for sites to comply with numeric effluent limitations is significant because it establishes the threshold at which developers and contractors must manage their stormwater runoff more strictly. As of February 2014, the Environmental Protection Agency (EPA) set this requirement at 10 acres. This guideline aims to ensure that larger sites implement appropriate measures to control the quality of stormwater discharges, as they have a higher potential to contribute to water pollution. By requiring numeric effluent limitations, the regulations compel site operators to adopt best management practices that minimize erosion, sedimentation, and pollutant runoff into nearby water bodies. Consequently, those operating on sites smaller than this agreed-upon limit may not be subject to the same stringent regulations regarding effluent quality, helping to focus regulatory efforts where they can yield the most significant environmental benefits.
