NOTICE OF PROPOSED WATER POLLUTION CONTROL PERMIT FOR
SMALL MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4)
ISLAND OF OAHU
NPDES PERMIT NO. HI S000009

DOCKET NO. HI S000009

January 15, 2015

The Department of Health (DOH) tentatively proposes to issue a National Pollutant Discharge Elimination System (NPDES) permit to discharge municipal storm water runoff and certain non-storm water discharges which are collected by the MS4 into State Waters or into adjacent separately-owned storm drainage systems subject to special conditions to:

STATE OF HAWAII
DEPARTMENT OF LAND AND NATURAL RESOURCES (DLNR)
DIVISION OF BOATING AND OCEAN RECREATION (DOBOR)
333 QUEEN STREET, SUITE 300
HONOLULU, HAWAII 96813

The proposed draft NPDES permit will expire five (5) years after the effective date of the permit.

The DLNR, DOBOR owns and operates Small MS4s at seven (7) facilities on the Island of Oahu. The Small MS4s are a system of conveyances, including storm drains, catch basins, curbs, and gutters, canals, and ditches, designed to collect and convey storm water runoff and certain non-storm water discharges at each facility. The volume of discharge is dependent upon rainfall-induced runoff and usage and is highly variable.

The goal of this proposed draft NPDES permit is to reduce storm water runoff pollution from the Small MS4 to the maximum extent practicable. This will be achieved through the implementation of the Permittee’s Storm Water Management Plan which is an enforceable component of the proposed draft NPDES permit.

The DLNR, DOBOR Small MS4s serve in the coastal areas of parts of the Island of Oahu. The receiving waters include Class A and Class AA, Marine Waters. It is the objective of Class A waters that their use for recreational purposes and aesthetic enjoyment be protected. Any other use shall be permitted as long as it is 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. The objectives of Class AA are the same as for Class A, with an additional objective that they shall retain their natural and pristine state as nearly as possible, with an absolute minimum of pollution or alteration from any human-caused source of pollution.

Persons wishing to comment upon or object to the proposed NPDES permit or to request a public hearing, should submit their comments or requests in writing no later than 30 calendar days after the date of this notice, either in person or by mail, to:

Clean Water Branch
Environmental Management Division
Department of Health

Honolulu, HI 96814-4920

If DOH’s position is substantially unchanged after considering all timely written comments and all oral comments at any public hearing that may be held, then the DOH will issue the NPDES permit and this action will be final.
