POH-2013-00138

Published Jan. 17, 2014
Expiration date: 2/17/2014

Interested parties are hereby notified that an application has been received for a Department of the Army permit for certain work in waters of the United States as described below and shown on the attached drawings.

APPLICANT: Mr. Derek George, Marine Corps Base Hawaii

AGENT: Mr. Aaron Poentis, Naval Facilities Engineering Command, Hawaii

LOCATION: Waterfront Operations Facility at the end of Sumner Road at the extreme western end of Marine Corps Base Hawaii on Kaneohe Bay, Island of Oahu, Hawaii (TMK: (1) 4-4-08:001).  Latitude: 21.450070 N; Longitude:  -157.777581 W

PROPOSED WORK: The proposed work includes the demolition of an existing 11.8-feet-wide by 61.4-feet-long, concrete boat ramp followed by the construction of a new boat ramp which would be 15.7-feet wide and 82.7-feet long.  To accomplish this, the proposed work plan includes the relocation of corals in the vicinity of the boat ramp located on both existing rip rap and natural substrate, as detailed in the attachments and the Navy’s letter dated March 14, 2013, to the National Marine Fisheries Service (see also Mitigation below).

Once coral relocation is complete, full-depth silt/turbidity curtains would be deployed around the construction area prior to in-water work. Existing rip-rap material would be relocated by hand to adjacent areas outside of the construction area.  Demolition of the existing concrete boat ramp would include the removal of 637 square feet of existing concrete ramp slabs by using an excavator to “bite” off pieces to be lifted safely out of the water. After removal of the concrete slabs, the same excavator would be used to excavate the footprint of the new boat ramp, which would include the removal and disposal of 21.5 cubic yards of material. The Manitowoc M80 crane with clamshell bucket would be used to excavate the pocket for the toe of the ramp.

The Manitowoc M80 crane would be used to lay 20.5 cubic yards of the new graded granular fill base cushion for the new boat ramp, and a weighted screed beam would be used to level the granular fill into the final position underwater on a steel beam leveling frame. The crane would then be used to place rip rap at the base of the ramp to lock in and support the weight of the pre-cast panels.  Using the crane, new precast concrete panels would be lowered into place on top of the leveling frame to form the deck surface of the new boat ramp.

All heavy equipment would remain on land above the mean high tide line, and only the cable rigging and bucket of the crane/arm and bucket of the excavator would enter the water during the course of the work. Please see the attached for additional information on the proposed demolition and reconstruction of the boat ramp.

PURPOSE: To provide adequate access from the Waterfront Operations Facility on Marine Corps Base Hawaii to Kaneohe Bay for emergency responders and capability for launch and recovery of vessels as efficiently and safely as possible for daily training and operations.

ADDITIONAL INFORMATION: The discharge of fill material would be necessary to construct the replacement boat ramp and to ensure its stability after construction.  Fill materials that would be discharged include new geotextile, granular fill base course and steel leveling frame to support the new boat ramp, pre-cast concrete slabs, and new rock rip rap to be installed around the sides of the new boat ramp to prevent erosion.

PLEASE NOTE: Application included the proposed construction of an outfall in addition to the reconstruction of the boat ramp. The outfall construction was provisionally authorized under Nationwide Permit #7 at an earlier date pending receipt of Water Quality Certification from the Department of Health – Clean Water Branch. Therefore, the proposed information being reviewed is only for the proposed boat ramp reconstruction per this public notice.

MITIGATION: Best management practices (BMPs) that would be implemented during construction include the use of full-depth silt curtains to enclose all in-water work; bermed drying area where excavated material will be dried out in a designated containment cell, which would be bermed on all sides and lined with impermeable plastic sheeting to prevent return water to the bay; relocation of rip rap by divers rather than machinery for minimal disturbance to the adjacent aquatic environment; secondary containment for fuel; and avoidance measures for the protection of marine life.

Avoidance and minimization of effects to coral reef adjacent to the proposed project site would include the transplantation of coral colonies to suitable receptor sites on the adjacent reef.  This action would occur prior to the start of in-water construction work.  All transplanting would be done during high tide.  Trained divers would carefully count, identify, label, and move corals a short distance (less than 75 feet) to a nearby reef. Divers would remove coral by hand using chisels and prying.  The corals would not be removed from the water at any time, would be kept at the same depth during relocation to avoid stress, and would be moved to a non-marginal habitat for increased likelihood of survival. Divers would assess the receiving area and mark suitable areas with floats/tags.  Coral colonies would be wedged and secured into the interstitial spaces in the receiving areas. Markers would be installed for future identification and monitoring. No chemicals would be used. Please see the attached letter from the Navy to the National Marine Fisheries Service for additional details on the coral transplantation plan.

The applicant’s proposed work did not specifically identify any compensatory mitigation.

WATER QUALITY CERTIFICATION: The Corps may not issue a DA permit for any activity that may result in a discharge into waters of the United States until the applicant has obtained from the State of Hawaii Department of Health a certification or waiver of certification as required under Section 401 of the Clean Water Act.

COASTAL ZONE MANAGEMENT ACT CERTIFICATION: Section 307 of the Coastal Zone Management Act of 1972, as amended, requires federal activities directly affecting land or water uses in the Coastal Zone to be conducted in a manner which is, to the maximum extent practicable, consistent with the enforceable policies of the State’s approved Coastal Zone Management Program.  Marine Corps Base Hawaii (MCBH) has determined, by letter dated March 5, 2009, that the proposed project is located on Federal land and within the “Defensive Sea Area”, which are excluded from the State’s coastal zone.  In addition, MCBH has determined there would be no reasonable, foreseeable direct or indirect effects on any coastal use or resources of the State’s coastal zone.

CULTURAL RESOURCES: MCBH has determined, by letter dated February 11, 2009, that the proposed project would result in no historic properties affected within the area of potential affect. By letter dated February 23, 2009, the State Historic Preservation Office concurred with MCBH’s determination.

ENDANGERED SPECIES: Section 7 of the Endangered Species Act (ESA) requires federal agencies to consult with the National Marine Fisheries Service (NMFS) and/or U.S. Fish and Wildlife Service (USFWS) to ensure that any action they authorize, fund, or carry out is not likely to jeopardize the continued existence of species listed as threatened or endangered under the ESA or result in the destruction or adverse modification of designated critical habitat. 

By letter dated March 5, 2009 to NMFS, MCBH determined that the proposed project would not adversely affect species listed as threatened or endangered and requested concurrence. By letter dated April 20, 2009, NMFS concurred with MCBH’s determination that the proposed project may affect, but would not likely adversely affect ESA-listed marine species or their designated critical habitat.

By letter dated January 14, 2009 to USFWS, MCBH determined that the proposed project may affect, but would not likely adversely affect species listed as threatened or endangered, specifically the Hawaiian stilt, and requested concurrence. By letter dated March 12, 2009, the USFWS concurred with MCBH’s determination the proposed project may affect, but would not likely adversely affect the Hawaiian stilt.

ESSENTIAL FISH HABITAT: The proposed work is being evaluated for possible effects to Essential Fish Habitat (EFH) pursuant to Section 305(b) of the Magnuson-Stevens Fishery Conservation and Management Act of 1996 (MSFCMA) (16 U.S.C. 1855 (b)) and associated federal regulations found at 50 CFR Part 600 Subpart K.  The Honolulu District area of responsibility includes EFH for species managed under Fishery Management Plans. 

By letter dated March 14, 2013, MCBH determined that the proposed project would adversely affect EFH, requested consultation for effects to EFH with NMFS, and detailed in the letter the avoidance and minimization efforts, including coral transplantation, that are proposed to reduce adverse effects. By letter dated April 23, 2013, NMFS responded and concurred with MCBH’s effects determination, as well as offering 5 conservation recommendations for MCBH to consider when implementing the avoidance and minimization plan.
