  • 2015-110 George Harms

    Expiration date: 4/8/2015

    The applicant proposes to conduct maintenance dredging, by mechanical (clamshell bucket) method, from a barge, within the waters of Manasquan River. The maximum area of dredging is 0.217 acre (9,444 square feet), and the maximum depth would be 6 feet below the elevation of MLW. The project site is adjacent to the Manasquan River federal navigation project (minimum 150 feet away). It is proposed to dredge up to 199 cubic yards for the initial event. Dredged material would be initially placed in watertight containers on barges at the dredge site, and transported by barge across the river to the upland off-load site in Point Pleasant Beach for dewatering and transfer to trucks. Dewatering would be accomplished by surrounding with hay bales and silt fence prior draining water from containers. Trucks would haul the material to the Ocean County landfill for final disposal.

  • 2014-22 Wernersville State Hospital

    Expiration date: 3/21/2015

    The applicant proposes to perform a total of 1,585 linear feet stream channel restoration along Hospital Creek within the Wernersville State Hospital property. The project can be broken into 4 subsections: A) 680 linear feet of stream restoration within the Mill Dam basin (including Mill Dam removal) immediately at and upstream of the dam, B) restoration of 495 linear feet of waterway immediately below the Mill Dam (including removal of the stilling basin area with ensuing, C) downstream restoration of 100 linear feet of stream below the Sportsman Road crossing, and D) the downstream restoration of 310 linear feet of stream just below the Main Street creek crossing including removal of a small concrete check dam. The proposed project would result in the disturbances to 2.45 acre of regulated waters including 0.37 acre of wetlands associated with the conversion of wetland to stream channel and 2.08 acres of open waters below the ordinary high water mark associated with stream channel re-construction and enhancement. It should be noted that the mill dam, a PADEP Category 1 Hazard Potential Dam, was drawn down in 1986 due to safety concerns and potential for a dam failure.

  • 2013-1009

    Expiration date: 4/5/2015

    The U.S. Fish and Wildlife Service (Service) proposes to construct an ecosystem restoration project within the Prime Hook National Wildlife Refuge (NWR) in Sussex County, Delaware. The refuge was established in 1963, stretching along the southwestern shore of Delaware Bay just north of Cape Henlopen in Sussex County, and encompasses 10,144 acres of tidal salt-marshes, agricultural lands and upland forests, bordering on three bay-front communities: Slaughter Beach, Prime Hook Beach and Broadkill Beach. The refuge was established under the authority of the Migratory Bird Conservation Act and provides an important stop-over site for migratory birds that travel the Atlantic Flyway. It also provides breeding habitat for federally and state-listed threatened and endangered species, as well as many neo-tropical migrating bird species.

  • 2008-777 Fishermen’s Energy of New Jersey, LLC

    Expiration date: 3/28/2015

    Approximately 2.8 miles east of Atlantic City, Atlantic County, New Jersey PROPOSED PERMIT MODIFICATION: In a letter dated December 3, 2014, Fishermen’s Energy, LLC requested that this office modify the above referenced Department of the Army permit. The following changes have been requested: The permittee would install six (6) 4 megawatt turbines, with a maximum output of approximately twenty five (25) megawatts. Each of the three (3) turbine blades would be two hundred thirteen (213) feet long, as opposed to the previously approved one hundred ninety two (192) foot long blade. The turbine hub height would be up to two hundred ninety seven (297) feet above mean high water, as opposed to three hundred (300) feet above mean high water. The lowest the turbine blades would be during rotation is eighty (80) feet above mean high water as opposed to one hundred (100) feet, and the highest the turbine blade would be during rotation would be five hundred seven (507) feet above mean high water as opposed to five hundred (500) feet. The jacket foundations would be changed, requiring the installation of four (4) eighty four (84) inch piles that would be driven through ninety (90) inch sleeves used to support the turbine. The issued permit authorized a monopole installation and was modified to allow for the installation of a total of eighteen (18) forty eight (48) inch diameter piles. The pilling sleeves are incorporated into the base of the turbine structure. The work would be performed using either a jack-up barge or a floating crane barge. The maximum sound generation for each pile would be approximately 199 dB (re 1 uPa) at the source, which as not chaged from the previously approved permit. The structural braces for the towers would be seventy two (72) inches in diameter and would be located laterally along the foundation. Due to the redesign of the towers, there will be no need for the placement of filter or armor stone at the project sites. No discharge of dredged or fill material is now proposed for the installation of the individual wind turbines. All submarine electric cables would be buried to a target depth of approximately six (6) feet below mean low water as opposed to nine (9) feet. The depth of the cable below the Federal beach nurishment project along the Atlantic City Beach will be twenty (20) feet instead of twenty seven (27) feet under the beach. The cable that would run from the turbines to the shore would be five (5) inches in diameter as opposed to eight (8) inches in diameter. The applicant has also requested that the expiration date of the permit be extended from December 31, 2015 to July 31, 2018. All remaining aspects of the project, including staging sites, vessel traffic, color and labeling of the turbines, seasonal restriction and maintenance schedules would remain unchanged from that previously approved by this office.
