The proposed modification consists of the maintenance dredging the Cricket Cove Marina through a combination of mechanical and hydraulic means.  In detail the applicant is requesting a 10 year maintenance dredging permit that includes a combination of hydraulic and mechanical dredging, as needed, to ensure navigable depths over a total of 5.3 acres to include the marina basin and areas adjacent to the AIWW required for continued marina operation. Prior to the Tidewater CDF availability, the work entails removing approximately 15,000 cubic yards of material by a barge mounted mechanical excavator. Excavated material will be placed onto a barge with three foot high bin walls.  Each scupper hole in the bin wall will be fronted with a bale of wheat straw to ensure any supernatant will have sediment filtered before reentering the water column.   The material will be transported by barge to the 2nd Avenue South boat ramp and the AIWW.  There, material will be transferred to a dump truck and hauled to an existing dump site (TMS 130-00-08-138) currently utilized by Vereen Concrete.

Once the Tidewater CDF is available, hydraulic dredging will be utilized to remove approximately 130,000 cubic yards of material over a 10 year period. Initial hydraulic dredging will remove approximately 40,000 cubic yards of material with the remainder to be removed over two (2) subsequent hydraulic maintenance dredging events. Dredged material will be pumped to the Tidewater CDF located on Little River Neck Road, in North Myrtle Beach, Horry County, South Carolina. The applicant stated that consent agreements with both Horry County and the U.S. Army Corps of Engineers will be negotiated for the proposed use of the CDF. Once the material has sufficiently dried, it will be hauled to the final disposal site identified as TMS# 144-00-01-115 located in Horry County, South Carolina.

The applicant offered no mitigation and stated that: Impacts are insignificant and therefore no mitigation is required. The project purpose is as stated by the applicant is: to enhance water depths for safe passage of watercraft by performance of maintenance dredging.
