Now, Appendix H of the Emergency Response Plan was, was written sometime in the 1980's
<br />using the Industrial Source Code [Complex] Model, which is a sort of a basic Gaussian
<br />dispersion model, which is, you know, an okay model, but it's, you know, it's a quarter of a
<br />century old, and there—there are new models available. And, there are new, I mean, PGV has
<br />changed since the 1980's, and so, we need to know what their upset conditions are presently, not
<br />what they were 25 years ago.
<br />So, there's a great need for an update of this Appendix H, and so now we have a couple of
<br />candidate models. One is the Vog Model that Dr. Businger uses for Kilauea and there's another
<br />one called CALPUFF which is used at Lake County in The Geysers geothermal plant. It, the
<br />CALPUFF is actually an EPA approved model for this particular application, but what we need
<br />to do is a validation program to make sure that these models actually work in this particular
<br />location.
<br />And, so what we're proposing to do here is do some studies and try to give ourselves some
<br />assurance that the new models that we're looking at will do the job, will actually perform as
<br />they are supposed to. And, so that's, that's basically what we're trying to do here with this
<br />program, and I hope you will offer your support to it.
<br />BUSINGER: Good morning, and thank you for your time in assessing this program. My name
<br />is Dr. Steven Businger. I'm a professor and chair of the Atmospheric Science Department at the
<br />University of Hawaii at Manoa. I have been doing dispersion modelling for 30 years. I'm also
<br />a fellow of the AGU and a fellow of the AMS. I think that Chris has really given a nice outline
<br />of what it is we hope to accomplish, and I have been doing dispersion modelling of the vog
<br />plume and to make that available publicly on-line, you may be available—may be familiar,
<br />rather, with that model. And, that model started in 2010, and it's been validated over time, and
<br />as Chris mentioned, it's very important for us to validate these dispersion models so that we get a
<br />tool that really provides guidance to the stakeholders, including the community, Civil Defense,
<br />and so on, and the Health Department.
<br />I'mmy presence here today, I flew over from Honolulu, is to allow you to answer questions, to
<br />ask questions that are of a technical nature, and I'd be more than happy to answer any questions.
<br />Thank you.
<br />PETRICCL Aloha, Commissioners, and good morning. My name's Robert Petricci. I'll be
<br />speaking for Puna Pono Alliance today, and I, first I want to talk about Chris. You were really
<br />lucky to have a guy like that. He worked for the Army for many years on their chemical
<br />weapons disposal monitoring, and he was the head of that program. And, he's doing this all as a
<br />voluntary effort so the County is very, very lucky. We're saving a lot of money to—we can have
<br />a state-of-the-art system here, and I hope you guys will pay attention to that.
<br />And, as Duane can verify, when this whole permitting process went into place, that's what these
<br />funds were for. And these funds have been used for things like bus stops and paving roads, and
<br />other things that I don't think they were intended for, so I hope that we can now find the money
<br />after 35 years, really, since HPA [sic], to finally have some kind of monitoring program that the
