Cultec Meets EPA Stormwater Phase II Regulations

The Environmental Protection Agency (EPA) requires the control of stormwater runoff since the passage of the Clean Water Act (CWA). Stormwater discharges are generated by runoff from land and impervious areas such as paved streets, parking lots, and building rooftops during rainfall and snow events. These discharges often contain pollutants in quantities that could adversely affect water quality. Most stormwater discharges are considered point sources and require coverage by a National Pollutant Discharge Elimination System (NPDES) permit. The primary method to manage stormwater discharge is through the use of best management practices (BMPs) which help reduce the quantity and improve the quality of stormwater runoff. One BMP solution is underground stormwater storage by infiltration (exfiltration) basins. A benefit to using this type of system is simultaneous pollution prevention and regeneration of lakes, rivers and other natural water resources. Infiltration systems are one of the few means that provide significant groundwater recharge in areas with a high percentage of impervious surface area.
