paved, steep, winding, two-lane County maintained road. The park access will be gated and will remain open during normal park hours and closed at night. 25. Water: According to the applicant, there is no County or private water system available to the subject property. Water for the park is currently hauled in by privately operated water supply trucks and is non -potable to only be used for flushing and washing hands. The proposed project includes the demolition of the existing non -potable water storage and the construction of a new potable water storage system, including a new water tank and booster pump(s), for the new comfort station. Potable water would be delivered by privately operated water supply trucks. 26. Wastewater: There is no municipal sewer system in Miloli`i. According to the applicant, the existing park is currently serviced by an Individual Wastewater System (IWS) comprised of a septic tank and leach field. Residents of the area have expressed concerns over high bacteria levels around the beach park. An IWS Assessment and Feasibility Study for Miloli `i Beach Park as shown in Appendix D of the FEA was completed in August 2020. In general, the waters surrounding Miloli`i Beach Park are being negatively impacted by enterococcus. Samples near the entrance to the beach park and pavilion were found to have the highest enterococcus levels, which exceeded the limit for recreation waters. The shallow marine cove fronting the beach park was predicted to have the highest bacteria levels due to its proximity to the existing leach field. However, samples from this location were found to have the lowest enterococcus levels, well below the limits allowed for recreational waters. Additionally, a dye test was conducted and originated at the comfort station's septic tank and no dye was observed in the adjacent marine waters through the investigation period. The study concluded that the IWS appears to be adequate for low to normal usage periods, however it may be undersized for the estimated weekend use. Further investigation and testing during high usage periods is recommended, in addition to increasing the frequency of pumping from once every three months to once a month. The study also provided options to the Department of Parks and Recreation on other possible wastewater systems. At this time the Department of Parks and Recreation will provide a holding tank for toilet waste while continuing to use the existing IWS for the sink water.
