San Joaquin valley <br /> Air Pollution Control District R <br /> FpFr�c <br /> ca <br /> April 20, 1999 ,�/_74,, p'? 49 99 <br /> Kai Luoma <br /> San Joaquin County <br /> Community Development Department <br /> Development Services Division <br /> 1810 East Hazelton Avenue <br /> Stockton, CA 95205 <br /> SUBJECT: USE PERMIT FOR A REGIONAL CHURCH FOR UP TO 2,000 <br /> PERSONS TO BE COMPLETED IN PHASES (UP-96-2) <br /> Dear Mr. Luoma: <br /> The San Joaquin Valley Unified Air Pollution Control District has reviewed the proposed <br /> project and offers the following comments: <br /> The San Joaquin Valley's air quality has been designated nonattainment by the EPA <br /> and by the Air Resources Board (ARB) for 03 (ozone) and PM-10 (fine particulate <br /> matter, dust). The Federal Clean Air Act (CAA) and the California Clean Air Act require <br /> areas that are designated nonattainment to reduce emissions until standards are met. <br /> Based on the information provided, it appears that this project will generate an increase <br /> in localized traffic and therefore, an increase in vehicle emissions. Given the magnitude <br /> of this project, the vehicle emissions may exceed the District's thresholds of significance <br /> for the ozone precursors ROG, reactive organic gases, and NOx, oxides of nitrogen. <br /> The District's thresholds for ROG and NOx are 55 lbs/day for each pollutant. Additional <br /> ozone precursor emissions will be generated from the use of landscape and space and <br /> water heating equipment. As a result, the District requests that further air quality <br /> analysis be provided so that we may more accurately analyze this project's impacts. As <br /> discussed in the District's Guide for Assessing and Mitigating Air Quality Impacts <br /> (GAMAQI), this analysis should include emissions quantification and qualitative analysis <br /> of potential construction impacts. <br /> The construction phase of this project can generate emissions from the movement of <br /> soil, use of heavy equipment, bulk materials handling, asphalt paving and other related <br /> activities. As a result, this project is subject to District Regulation VIII (Fugitive <br /> Dust Prohibitions). The purpose of Regulation VIII is to reduce the amount of fine <br /> particulate matter (PM-10) entrained into the ambient air from man-made sources. The <br /> attached Synopsis highlights many of the requirements contained within Regulation VIII. <br /> The Synopsis is not meant to be all-inclusive, but it can be a useful compliance aid in <br /> the field and office alike. <br /> Northern Region Office Central Region Office Southern Region Office <br /> 4230 Kiernan Avenue, Suite 130 1990 East Gettysburg Avenue 2700 M Street,Suite 275 <br /> Modesto, CA 95356-9321 Fresno,CA 93726-0244 Bakersfield,CA 93301-2370 <br /> G'09!557-6400•FAX(209)557-6475 (559)230-6000•FAX(559)230-6061 (661)326-6900•FAX(661)326-6985 <br />
