Title:
Kahe Generating Station Daily Water Temp Data from 1992-97, (NODC Accession 9900021)
Abstract:
The Hawaiian Electric Company Inc. (HECO), under requirements of National Pollutant Discharge Elimination System (NPDES) Permit HI0000019, Section C.5, annually conducts and reports results of a monitoring program for waters receiving effluent from the Kahe Generating Station, O'ahu, Hawai'i. This data set includes daily water discharge and unadjusted intake temperature data logs collected as part of this monitoring program from 1992 to 1997 (Appendix B in annual reports). These data are filed under NODC Accession # 9900021.
Supplemental_Information:
Since January 1, 1986, HECO has used adjusted intake water temperatures as the reference against which temperature elevations of the thermal effluent are measured. Intake temperatures are adjusted downward by 0.42 C' to determine the reference temperature. Based on over 10 years of temperature records collected at an ambient temperature control station, it was determined that intake temperatures exceeded nearshore ambient bottom temperatures by this amount. Daily records were kept of maximum, minimum, mean effluent, and mean influent temperatures. Intake and discharge temperatures were recorded continuously using a Foxboro ERB strip chart recorder and Dynatherm* resistance bulbs.

Why was the data set created?

National Pollutant Discharge Elimination System (NPDES) permit HI0000019 authorizes HECO to discharge waste water from the Kahe Generating Station. A provision of this permit is that HECO follow a marine monitoring program and documents marine effects of cooling-water discharge from Kahe Generating Station Units 1 through 6. Specific studies covered under this program include monitoring of temperature elevations of thermal effluents, quantities of sediment entrainment and throughput, and reef coral communities. An annual report of the data, analysis, and findings of these monitoring studies is submitted to the State Department of Health (DOH) Director and Environmental Protection Agency (EPA) Regional Administrator no later than March 1 of each year.

  5. How consistent are the relationships among the observations, including topology?
    After 1973, HECO's Environmental Department conducted extensive NPDES marine monitoring studies to determine the conditions of the Kahe nearshore environment during the station's expansion to six generating units and the relocation of the Kahe shoreline outfall to its present offshore site (Coles and McCain, 1973; Coles and Fukuda, 1975, 1983, 1984; Environmental Department, 1976; McCain, 1977; Coles, 1979, 1980; Coles et al., 1981, 1982, 1985, 1986; Fukuda and Oda, 1987; Environmental Department, 1988, 1989, 1990, 1991, 1992, 1993 1994 and 1995). Several of these reports also document the impacts of major storms on the Kahe nearshore environment that occurred in 1980, 1982 and 1992, and the subsequent recovery of the storm-damaged areas that are influenced by power station operation. These NPDES monitoring reports were submitted to the HI State Department of Health upon completion and are herewith incorporated by reference. This investigation is a continuation of the monitoring programs documented in the referenced reports.
