EPA issues new regulation for stormwater permitting

US EPA regulations have required that operators of construction activity that involves more than one acre must control stormwater leaving the construction site through use of a Construction General Permit (CGP) and a Stormwater Pollution Prevention Plan (SWPPP).  On January 11, 2017 EPA issued the new 2017 CGP regulation which still require compliance with effluent limits and other historical permit requirements, including the development and maintenance of a SWPPP, but an updated set of requirements for stormwater runoff at construction sites took effect on February 26, 2017.  Additional information is available at https://www.epa.gov/npdes/stormwater-discharges-construction-activities#cgp.
