NEW ORLEANS - A federal judge in Louisiana on July 1 denied an oil production platform owner's attempt to dismiss claims for violating the Clean Water Act (CWA) and Outer Continental Shelf Lands Act (OCSLA) for excessive discharges of oil in wastewater, finding that two exclusions to CWA liability are inapplicable (United States of America v. ATP Oil & Gas Corporation, et al., No. 13-0262, E.D. La.; 2013 U.S. Dist. LEXIS 91946).
