potential for adverse air quality effects associated with implementation of Kumu Hou. Air quality emissions are assessed for construction and operational activities. The study focused on air pollution from two (2)perspectives: 1) daily emissions and 2)pollutant concentrations. TAHA concludes that the Kumu Hou project should not generate any direct, long-term air quality impacts. 36. Water Quality: Tom Nance Water Resource Engineering (TNWRE) conducted a study examining the potential impacts of Kumu Hou on water resources of the area(see Appendix 6 of the application). The study found that the proposed project could impact water resources such as drinking water, wastewater, and the brackish water wells. According to the applicant, the project is anticipated to need approximately 520,900 gallons per day (GPD) of potable water(Area A and B only, Area C will not generate a demand for potable water). Drinking water for the project site will be obtained from the private Waikoloa Water System, whose source is extracted from wells located in the Waimea Aquifer System (WAS). At full buildout(c. 2042) the Kumu Hou development will require an increase of 0.52 to 0.54 million gallons per day (MGD) in potable water needs which accounts for a 10% increase from current withdrawal amounts. It is estimated the current pumpage from the WAS is approximately 13.2 MGD (from all sources) and the effective yield of the WAS is approximately 16.0 MGD. It is anticipated that the increase in water use will still be within acceptable amounts for the WAS. The Kumu Hou development will generate 0.38 MGD of wastewater which accounts for a 30% increase from current levels of wastewater production. Currently, the resort treats its wastewater to an appropriate standard (R-1) that can safely be used for irrigation of the golf course. Currently 17% of the irrigation water used at the golf course comes from treated wastewater; the proposed development will increase the use of wastewater for irrigation to 26%thus reducing the amount of water drawn from groundwater sources. Groundwater for the resort is taken from the `Anaeho`omalu Aquifer System (AAS). It is estimated that the landscaped areas of Kumu Hou will require approximately 0.31 MGD for irrigation. A new brackish water irrigation system located in "Area U will provide the needed water for landscaping irrigation thus reducing the need to extract potable water from the WAS for irrigation. The applicant believes the proposed elimination of -16-
