FOR WAIMEA RIVER MOUTH MAINTENANCE
WAIMEA, ISLAND OF KAUAI
NPDES PERMIT NO. HI S000561
DOCKET NO. HI S000561
January 24, 2019
The State Department of Health (DOH) tentatively proposes to issue National Pollutant Discharge Elimination System (NPDES) permit to discharge storm water associated with construction activity from the Waimea River Mouth Maintenance project site, to receiving State waters, subject to special conditions to:
DEPARTMENT OF LAND AND NATURAL RESOURCES
1151 PUNCHBOWL STREET, ROOM 220
HONOLULU, HAWAII 96813
The proposed NPDES permit for the new discharge will expire five (5) years from the date of issuance.
The project is located at the mouth of the Waimea River and Kikiaola Beach, Waimea, Island of Kauai, Hawaii, TMKs: (4) 1-6-006:003; (4) 1-2-013:001, 003, 039, 040, and 041; and as shown in the revised application, dated October 15, 2018.
The purpose of the project is to excavate and dredge sand from the Waimea River mouth sandbar to widen the outflow channel from the river to the ocean. The dredged sand will be dewatered in a containment structure and transported to the fill site at Kikiaola Beach. The dredged sand will be placed above the two-foot (2′) elevation which is above the Mean Higher High Water (MHHW) mark elevation of 1.01-foot (1.01′), and below the vegetation line. The permittee is responsible for the design, implementation, operation and maintenance of the Storm Water Pollution Prevention Plan (SWPPP) to ensure that storm water discharges associated with construction activities will not cause or contribute to a violation of HAR, Chapter 11-54; Chapter 11-55; Chapter 11-55 Appendices C. Best Management Practices (BMPs) for storm water runoff and non-storm water sources will be implemented to minimize the discharge of erosion and other pollutants from entering receiving State waters.
The receiving waters, Pacific Ocean at Waimea River and Kikiaola Beach, is classified by the DOH as Class A, Marine Water. The objective of Class A waters is to protect their use for recreational purposes and aesthetic enjoyment. 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. No new sewage discharges will be permitted within embayments.
