55 dBA at the property line. That's what we are moving forward with in the construction, in the <br />design and construction of this plant for normal operations. <br />CLARKSON: Thank you. Any other questions from any Commissioners on this matter? Do <br />you have—okay. <br />YAMAMOTO, W.: Just a quick clarification. So, Mr. Lee briefly mentioned when he was <br />speaking regarding the lifting of the safety valve whenever you have a turbine startup for <br />example or release of the steam, that at the source you could have 55, above 55 dBA or above 70 <br />dBA at the source of the sound. Now, given that the source of the sound is at the main plant <br />building, which is centrally located within the entire property, and given that it's hundreds of feet <br />away or perhaps over a thousand feet away from the property boundary, we don't exactly know <br />what the dBA level is going to be at the property boundary, but we know at the source it's going <br />to be above 55 or 70 that may translate to you less than 55 or potentially above 55. We are just <br />not sure at this time because it's never been operated yet. But, we wanted to account ahead of <br />time for those instances, and they are going to be very limited in duration. <br />DELA CRUZ: Warren, you know your guys' noise abatement system, is it the same thing that <br />you guys did in Keahole? Same type? <br />LEE: You mean Keahole? <br />IKEDA: Yeah, the Keahole power plant. <br />LEE: Basically, to explain, Keahole power plant is a little different. It has <br />DELA CRUZ: But the noise abatement is pretty amazing out there, I mean, you can walk <br />through that whole plant, and it sounds exactly like this room right now. <br />LEE: Well, if you walls at the property line. <br />DELA CRUZ: Yeah. <br />LEE: Once you open the door, you might <br />DELA CRUZ: Yeah, if you open the door, it's another story, but <br />LEE: —find it pretty noisy. Yes, we did do a significant amount of sound studies, we insulated <br />the plant, it has a cooling tower, and we, well HELLO, installed low -speed [inaudible] fans to <br />move the circulating air, and also insulated so to [inaudible] less noise and insulated the <br />structures. And, this is a same concept that we are employing for sound mitigation for the Hu <br />Honua plant. <br />DELA CRUZ: Thank you. <br />LEE: You're welcome. Thank you. <br />I0V1111.11 11 <br />
