Abstract: The purpose of this Environmental Assessment (EA) is to evaluate the impacts of changes to the Congressionally authorized Delaware River Main Channel Deepening (DRMCD) Project, from that described in the 1992 Environmental Impact Statement (USACE, 1992), 1997 Supplemental Environmental Impact Statement (USACE, 1997), 1998 Record of Decision (USACE, 1998) and the 2009 and 2011 Environmental Assessments (USACE, 2009 and 2011). Specifically, this document addresses economic loading of hopper dredges and hopper scows in the Delaware Bay portion of the DRMCD Project, the use of mechanical dredging in project reaches other than the rock removal area, and placement of dredged material from the upper reaches of the project in the existing Federally-owned Fort Mifflin Confined Upland Disposal Facility (CDF). Evaluations of impacts on resources addressed previously in the Environmental Impact Statement (1992 EIS), Supplemental Environmental Impact Statement (1997 SEIS), and Environmental Assessments (2009 EA and 2011 EA) are not discussed in this EA and are incorporated by reference. The 2011 Biological Assessment (USACE, 2011a) and the 2012 Biological Opinion (NMFS, 2012) prepared for the project are also incorporated by reference.
