The Department of the Navy is requesting a modification of Department of the Army permit to rehabilitate and modernize Berth 1 of the existing X-Ray Wharf in Inner Apra Harbor on Naval Base Guam, the USACE just announced.
Under this application, the Navy is requesting an increase to the authorized construction dredging volume and area for the P-518 project.
“The overall dredging footprint remains unchanged, but four additional areas within the approach channel and turning basin/berth areas require dredging as identified during an August 2016 pre-dredge hydrographic survey,” the USACE said in its release.
According to the application , the permit modification would add an estimated 79.540 cubic yards (CY), including a -2.0 feet of overdredge allowance, of dredging to the originally permitted volume of 51.000 CY to achieve a -35.0 feet mean lower low water (MLLW) navigational depth in the project footprint.
All off the dredged material has been determined suitable for disposal at the Guam Deep Ocean Disposal Site (GDODS), as originally permitted. The new dredging locations will not impact any special aquatic sites, including coral reefs, the announcement said.
Comments will be accepted until February 3, 2017.
