NPDES PERMIT NO. HI 0021836
August 14, 2009
The Department of Health (DOH) tentatively proposes to issue a National Pollutant Discharge Elimination System (NPDES) permit to discharge hydrotesting water to receiving State waters, subject to special conditions to:
CITY AND COUNTY OF HONOLULU
DEPARTMENT OF DESIGN AND CONSTRUCTION
650 SOUTH KING STREET, 11TH FLOOR
HONOLULU, HAWAII 96813
The proposed permit for the new discharge will expire five (5) years from the date of issuance.
The Permittee proposes to discharge treated hydrotesting water associated with the repair of the digester tank covers at the Kailua Regional Wastewater Treatment Plant located in Kailua, Oahu, Hawaii. The source water used for hydrotesting activities consists of potable water. The hydrotesting process may introduce silt and chlorine to the potable water. As a result, the hydrotesting water shall be filtered and dechlorinated prior to discharge into the receiving waters.
The hydrotesting water will be discharged into Nuupia Ponds through Outfall Serial No. 001, located at: Latitude 21 26’09″ N and Longitude 157 45’17″ W.
Nuupia Ponds is classified as Class 1, Inland Waters under Hawaii Administrative Rules (HAR), Section 11 54 3(b)(1), 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. The uses to be protected include scientific and education purposes, protection of native breeding stock, baseline references from which human-caused changes can be measured, compatible recreation, aesthetic enjoyment, and other nondegrading uses which are compatible with the protection of the ecosystems associated with waters of this class.
