NOTICE OF PROPOSED
WATER POLLUTION CONTROL PERMIT
FOR MARINE CORPS BASE HAWAII (MCBH) KANEOHE BAY MUNICIPAL SEPARATE
STORM SEWER SYSTEM (MS4)
NPDES PERMIT NO. HI S000007
DOCKET NO. HI S000007
July 1, 2021
The State Department of Health (DOH) tentatively proposes, subject to public comments, to issue a renewal National Pollutant Discharge Elimination System (NPDES) permit to discharge storm water runoff and certain non-storm water discharges which are collected by the Municipal Separate Storm Sewer System (MS4) and storm water discharges associated with industrial activities into receiving State waters or into adjacent separately-owned storm drainage systems subject to conditions, limitations, and requirements in the NPDES permit and in accordance with State water pollution control law contained in Hawaii Administrative Rules Chapters 11-54 (Water Quality Standards) and 11-55 (Water Pollution Control) to:
U.S. MARINE CORPS BASE HAWAII
MCBH KANEOHE BAY
Box 63002, Building 1360
MCBH Kaneohe Bay, Hawaii 96863-3002
The proposed permit for the discharge will expire five (5) years from its effective date and will only authorize those discharges explicitly identified in the permit. The Permittee will be responsible for obtaining all other County, State, and/or Federal permits, licenses, and/or approvals as required by law.
MCBH owns and operates the MS4, which is a system of conveyances, including storm drains, catch basins, curbs, and gutters, designed to collect and convey storm water runoff at the Marine Corps Base Hawaii located in Kaneohe Bay, Island of Oahu, Hawaii. MCBH also includes industrial and commercial facilities.
The goal of this proposed NPDES permit is to reduce storm water runoff pollution from the MS4 to the maximum extent practicable. The discharge of pollutants from the Permittee’s industrial facilities shall be reduced to the appropriate discharge limitations based on the Best Available Technology currently available (BAT) / Best Conventional Pollutant Control Technology (BCT) discharge requirement. This will be achieved through the implementation of the Permittee’s Storm Water Management Program and Storm Water Pollution Prevention Plan, which are enforceable components of the proposed NPDES permit.
The receiving waters are designated as Class 1 Inland Waters in HAR 11 54 5 (Nuupia, Halekou, and Kaluapuhi Ponds), Class 2 Inland Waters in HAR 11 54 5 (portions of Mokapu Central Drainage Channel), Class AA Marine Embayment in Appendix B and HAR 11 54 6(a) (Kaneohe Bay and portions of Mokapu Central Drainage Canal), and Class A Open Coastal Marine Waters in HAR 11 54 6(b) (Kailua Bay). It is the objective of Class 1 and Class AA waters that these waters remain in their natural state as nearly as possible with an absolute minimum of pollution from any human-caused source. To the extent possible, the wilderness character of these areas shall be protected. Protected beneficial uses of Class AA waters include oceanographic research, the support and propagation of shellfish, and other marine life, conservation of coral reefs and wilderness areas, compatible recreation, and aesthetic enjoyment. It is the objective of Class A waters that their use for recreational purposes and aesthetic enjoyment be protected. The objective of Class 2 waters is to protect their use for recreational purposes, the support and propagation of aquatic life, agricultural and industrial water supplies, shipping, and navigation. Protected beneficial uses include uses compatible with the protection and propagation of fish, shellfish, and wildlife, and with recreation in and on these waters. These waters shall not act as receiving waters for any discharge which has not received the best degree of treatment or control compatible with the criteria established for this class.
