NOTICE OF PROPOSED WATER POLLUTION CONTROL PERMIT
FOR THE PEARL HARBOR NAVAL SHIPYARD AND
INTERMEDIATE MAINTENANCE FACILITY, DRY DOCKS 1 – 4
NPDES PERMIT NO. HI 0110230
February 15, 2008
The State Department of Health (DOH) tentatively proposes to reissue a National Pollutant Discharge Elimination System (NPDES) permit, including a Zone of Mixing (ZOM), for discharges to Pearl Harbor, subject to certain effluent limitations and special conditions to:
U.S. DEPARTMENT OF THE NAVY
PEARL HARBOR NAVAL SHIPYARD AND
INTERMEDIATE MAINTENANCE FACILITY
667 SAFEGUARD STREET, SUITE 100
PEARL HARBOR, HAWAII 96860-5033
The proposed permit will expire on September 30, 2010.
The U.S. Department of the Navy owns and operates a ship building and repair facility located at Dry Docks 1 – 4 at the U.S. Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility in Honolulu, Hawaii. Work at the facility is in connection with the construction, conversion, overhaul, repair, alteration, dry docking and outfitting of ships.
The sources of dry dock discharge water include: non-contact cooling water, seepage water, hull wash/hydroblasting water, hydrotesting water, pump test water, and rain water to Pearl Harbor from the four (4) dry docks located at the shipyard. Sanitary wastewater and main condenser hydroblasting water, and other process wastewaters are disposed of in the sanitary sewer system or industrial wastewater treatment plant.
Discharges are permitted through Outfall Serial Nos. 001, 002A, 002B, 003, 004A, and 004B. The outfall locations are specified below:
Outfall Serial No. Dry Dock No. Latitude Longitude
001 1 21E2115N 157E5730W
002A 1, 2, & 3 21E2100N 157E5730W
002B 1, 2, & 3 21E2100N 157E5730W
003 3 21E2100N 157E5730W
004A 4 21E2045N 157E5800W
004B 4 21E2045N 157E5800W
The ZOM shall be two (2) half-circular areas with a radius of 200 feet and centered at Outfall Serial Nos. 004A (Latitude 21E20\u00D545\u00D3N, Longitude 157E58\u00D500\u00D3W) and 004B (Latitude 21E20\u00D545\u00D3N, Longitude 157E58\u00D500\u00D3W) in the water area in Pearl Harbor off of Dry Dock No. 4. The zone extends vertically from the surface to the ocean floor. The proposed ZOM is for the assimilation of temperature effects from non-contact cooling water associated with work performed on commercial vessels only.
The receiving water, Pearl Harbor Estuary, is classified by the Department of Health as a Class 2, Inland Water. The objective of class 2 waters is to protect their use for recreational purposes, the support of aquatic life, agricultural and industrial water supplies, shipping, and navigation. The uses to be protected in this class of waters are all 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. No new sewage discharges shall be permitted within estuaries. No new industrial discharges shall be permitted within estuaries with the exception of acceptable non-contact thermal and dry dock or marine railway discharges within Pearl Harbor, Oahu and other discharges listed in Hawaii Administrative Rules, Chapter 11-54.
Anyone may comment upon or object to the proposed NPDES permit, including the ZOM, or request a public hearing, by submitting a written comment or request no later than 30 days after the date of this notice, either in person or by mail to:
