Abstract : Obtain signature for the Finding of. Significant Impact (FONSI) [Tab A] for the Supplemental Environmental Assessment (EA) [Tab B] for the Skfffes Creek Federal Navigation Channel Maintenance Dredging. a. In 2003, Fort Eustis prepared an Environmental Assessment (with a resulting FONSI) for dredging Skiffes Creek. The scope of that project involved dredging that p011ion of Skiffes Creek affecting operation of military watercraft/3d Pmt and disposing the dredge materials in the Fort Eustis Dredged Material Management Area (FEDMMA). This assessment included refurbishing of the FEDMMA. b. In 2012, dredging was scheduled again. However, a supplemental EA to the original EA prepared in 2003 was needed because several issues existed in 2012 that did not exist in 2003. This included the listing of the Atlantic sturgeon (Acipenser oxyrinchus oxyrinclws) as federally endangered (occurring in the James River), the presence of an active baldcagle (Haliaeetus leucocephalus) nest site near the project area and pesticide treatment of invasive common reed 1 ,Phragmites australis) in and around the FEDMMA. c. During the review process for the EA in 2012, it was determined that the FEDMMA was reaching the end of its life cycle and that refurbishing of the FEDMMA was once again needed. As a result other disposal options were evaluated. It was determined that an initial dredge would occur will disposal going to the Norfolk Ocean Disposal Site (NODS). A new SEA (Tab B) was prepared to evaluate the new issues addressed above. The outcome of this EA constituted a FONSI as well as a FONPA. A FONSl and FONPA are combined as one document. In the latter case, a FONPA was required per Air Force Instruction (AFI) 32-7064 because the project must occur within a I 00-year floodplain and may incur some wetland permitting. d. The new SEA (Tab B) was staffed through installation stakeholders as well as with external federal and state regulatory agencies. No significant issues were received.
