CSA International, Inc. (CSA) provided technical support in the development of an Environmental Impact Statement (EIS)/Overseas Environmental Impact Statement (OEIS) that addresses proposed shock testing of a new Navy vessel – the SAN ANTONIO (LPD 17) class amphibious assault ship, as represented by the MESA VERDE (LPD 19) – at several potential test sites in U.S. Atlantic and/or Gulf of Mexico waters. CSA prepared affected environment and impact text, as well as several technical appendices that address potentially sensitive resources (i.e., marine mammals; seabirds; marine turtles; commercial and recreational fish and fisheries; essential fish habitat; density and distribution estimates and incidental take estimates for protected marine mammal and sea turtle species).  CSA also provided technical and National Environmental Policy Act review of the EIS/OEIS.  Earlier efforts under this contract included developing EIS/OEIS affected environment and impact text for another new Navy vessel – the VIRGINIA (SSN 774) class submarine; this element was suspended by the Navy pending congressional funding approval.  CSA was a subcontractor to Booz Allen Hamilton.
