If you are following along and keeping a scorecard, then pay attention. Summer School is officially in session. The first iteration of the Vessel General Permit (VGP) expires on December 19, 2013. The Environmental Protection Agency (EPA) is issuing a replacement VGP permit under its authority from the Clean Water Act (CWA). The CWA and its implementing regulations contain standards that govern EPA’s imposition of National Pollution Discharge Elimination System (NPDES) permit conditions. The provisions of this permit are established under these authorities.
