YUASA: Condition No. 5 on Page 2 indicates that “The applicant shall use an aerobic septic treatment unit for the comfort station. This system shall be included in plans submitted for Plan Approval.” What we want to clarify is that when we designed this wastewater system, which consists of a septic tank and a leach field, we did go through Department of Health for their review and approval. And also I want to state that the septic tank/leach field system was designed in accordance with the Department of Health, Environmental Division, Wastewater Branch rules and regulations. And also I want to state that the leach field, or soil absorption field, is approximately 100 feet from the shoreline. And also, it’s constructed at elevation about 13, which would put the bottom of the absorption bed at about plus ten, so there is more than adequate separation between the groundwater and the bottom of the leach field, or absorption bed. The Department of Health rules call for minimum three-foot separation between the bottom of the leach field, or absorption bed, and the groundwater table; we have about seven feet separation in between.And also right now, as I said, we did work with the Department of Health, Wastewater Branch, and the funds were submitted in July, and hopefully real soon we should get formal approval of the wastewater system that was submitted. WATANABE: Okay. You realize that this recommendation came from, I believe it’s DLNR, yeah? Right? YUEN: Actually, what we put in was in response to something that was requested by DLNR, Aquatics Division. What they ask for seemed even a little more stringent, but this is what you can do that’s basically consistent with having a septic system and a leach field. They asked if I -. WATANABE: For contained system, I think it was. YUEN: A completely contained system. I’m not sure that that’s what they meant, but to me a completely contained system is something that you don’t have a leach field or a drainage field at all and you use, like, a pump-out system, which we thought was going overboard. WATANABE: Yeah, I just wanted to point out to you, Eric, that it’s not so much this Planning Department that is making this request of you, inclusive of the filtration that is in Condition 6; it’s DLNR. We are following their advice, who is, you know, the left hand – I guess you are the right hand in this case. YUASA: Chairman Watanabe, you are correct. The comments did come from our Division of Aquatic Resources, Kona Office, and they did request that we install holding tanks for the restroom wastewater system as well as the boat wash down because they felt that there’s a potential for contamination of the harbor waters, if the effluent or the runoff water would get into the ocean. We do not concur with their recommendations to put in a holding tank; we do not believe that it’s practical or that there is a potential for contamination. You know, addressing Condition No. 6 that requires us to “hire an engineer to design a subsurface filtration system utilizing material to filter oil, gasoline, various chemicals, soaps, bleach and fish blood for the boat wash down area. The filtration system shall be designed in EXHIBIT E 5
