EPA has agreed to re-examine ballast water treatment standards in a settlement agreement with several environmental groups after two years of litigation. NRDC. v. EPA, No. 09‑1089 (D.C. Cir. joint motion filed 3/8/11). Under the terms of the settlement agreement, EPA will pay the environmental groups more than $122,000 in attorney’s fees and will propose by November 2011 a new vessel permit that imposes numerical restrictions on the amount of organisms that can be present in a ship’s ballast water. Under the current permit issued in 2009, ships were required to either exchange ballast water with each other at ports of call or to flush their ballast water with sea water. Before 2009, ballast water and sewage from commercial ships were exempt from Clean Water Act discharge requirements. The settlement agreement is subject to public comment and court approval.
