Description:

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 report presents results of monitoring conducted during 1996 for water temperature, sand entrainment, and coral coverage. Replicate coral sampling indicated that significant changes in mean coral coverage occurred only at the station 300 m northeast of the Kahe outfall where significant reductions in the coral coverage have occurred in three of the previous four years since Hurricane Iniki in 1992. However, 1995-96 results indicated significant increases in coverage of the two major component species and in total live coral, the first time this has occurred at this station since Hurricane Iwa in 1982. Over the ten year term from 986 to 1996, this station registered significant reductions in coverage of the two dominant species and in total coral, despite the significant increases in coverage that occurred in 1995-96. The significant decreases in coral cover from 1986 to 1996 were direct effects from Hurricane Iniki, which occurred in September 1992. Results from 1996 monitoring support previous years' conclusions that the Kahe offshore outfall has produced negligible impact on the nearshore coral community and that natural storm disturbances have had greater destructive influence on reef coral coverage throughout the Kahe area. These data are filed at the NODC under NODC Accession # 9900012.

Purpose:

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.

Supplemental_Information:

The 1996 daily discharge and unadjusted intake temperature data log (Appendix B of this report) is provided under NODC Accession # 9900021, 'Kahe Generating Station 1996 Temperature Data.xls'

Logical_Consistency_Report:

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.

Methodology_Description:

Two categories of sediment were measured to estimate the total amount of sand presently being entrained by the Kahe Generation Station: 1) suspended and 2) bed load sediments.

Sediment throughput samples were taken at Units 1-4 and 5-6 discharge points within the Kahe outfall transition basin (Figure 1). Samples were collected by placing a 0.25-m diameter plankton net directly in the discharge. The 110 m mesh plankton net was held approximately 10 m behind the discharge ports for at least three minutes at a depth of 0.5 m. Flow rates determined with a General Oceanics digital flow meter were then used to calculate the total volumes of water sampled. Samples were collected four times in 1996, including two periods of medium to high surf. Pertinent data relating to weather and sea conditions were recorded. Measured amounts of suspended sediment were converted to units of ml/m3 by dividing by the total volume of seawater sampled. These were then extrapolated to daily throughput estimates by multiplying by the volume of cooling water circulated under operation of all six generating units (3.257 x 106 m3/day).

For bed load sediments, HECO operations personnel conduct pumping and record dates, durations and pumping rates to enable calculation of the total volume of sediment pumped from the forebays. Contractors are hired occasionally to pump or dredge sand from the forebays, intake or discharge basin, during which sand removal volumes are based on contractors' estimates. Whenever sediment was dredged, the volume removed was estimated by the number of truck loads required to transport the sediment to its deposition site.

Methodology_Description:

Ten permanent quadrats, each 0.66 m2 in area, were established in 1980 at each of the four stations. Each quadrat was marked with tagged metal stakes driven into the reef and cemented in place with underwater epoxy putty. These stakes have been used as reference points for photographing the bottom with a Nikonos 35mm underwater camera with a 28mm wide-angle lens mounted on a support frame. Photographs have been taken yearly since 1980, and missing stakes have been replaced as needed to maintain the quadrats as close as possible to their original location. In cases where the original quadrat was lost or could not be accurately located, new quadrats have been established to provide each station with a full complement of ten replicate quadrats. Of the original 40 quadrats established in 1980, 33 were still present in 1996 and used in long-term analysis of changes in benthic coverage on the reef.

Photographic transparancies of coral coverage at each quadrat were projected onto a white surface on which a rectangle had been drawn which corresponded to the camera stand's 0.66 m2 quadrat. The projected image of the camera stand quadrat was adjusted in size and position to assure a consistent projected area and view of a station's quadrat area between sampling years. Each photo-quadrat slide represents a permanent record of the condition of the coral reef at the time the photograph was taken.
