Air Quality Evaluation Sample Clauses

Air Quality Evaluation. To provide additional assurance that the PSELs for HAPs are sufficiently protective of human health, Intel, in consultation with EPA, ADEQ and MCESD, determined through screen modeling that the May 11, 1999 1-hour, 24-hour, or annual (if available) Arizona Ambient Air Quality Guidelines ("AAAQGs") will not be exceeded at the property line for any HAP listed in attachment 3 of this FPA if that HAP is emitted at its PSEL. The modeling is based on the conservative assumption that each chemical could be emitted at a constant level of 10 tons per year (or 1 ton per year in the case of phosphine or sulfuric acid and 14 pounds per year in the case of arsine), even though the PSELs limit aggregate emissions from all inorganic HAPs at 10 tons per year, and all organic HAPs at 10 tons per year. In addition to HAPs, Intel has performed screen modeling for a number of additional chemicals identified in attachment 3 of this FPA. An explanation of the screen modeling that has been completed for these chemicals is also provided in Attachment 3 to this FPA. Intel also is required by its air permit to undertake a screen modeling analysis in connection with the utilization of a new chemical that generates air emissions for which an AAAQG has been established, but which has not been subject to the screen modeling described above. That is, Intel will apply the conservative assumption that the new chemical will be emitted at a constant rate of 10 tons per year, or at a rate that corresponds to the expected emissions level for that chemical, and then utilize screen modeling to evaluate whether the AAAQG would be exceeded under such circumstances. Intel will limit annual emissions of any such chemical to below the appropriate AAAQG as predicted by the screen model3 at the property line.
