San Joaquin Valley RECEIVED Air Pollution Control District OCT 2 5 2005 Community Development Dept. October 24, 2005 Reference No.: 0200501404 Ms. Kathy Allen San Joaquin County Community Dev. Dept. 1810 East Hazelton Avenue Stockton, CA 95205 Subject: PA-0500699 (GP) pre-application—Arcadia Homes, Inc. (APNs 255-250-09; 255-180-04, -15; 255-260-13, -14, -16) Dear Ms. Allen, The San Joaquin Valley Unified Air Pollution Control District (District) has reviewed the project referenced above and offers the following comments: The entire San Joaquin Valley Air Basin is classified non-attainment for ozone and fine particulate matter (PM10). This project will contribute to the overall decline in air quality due to increased traffic and ongoing operational emissions. This project may generate significant air emissions and it will reduce the air quality in the San Joaquin Valley. The project will make it more difficult to meet mandated emission reductions and air quality standards. A concerted effort should be made to reduce project-related emissions as outlined below: Preliminary analysis indicated that the potential emissions from this project exceed the District's Thresholds of Significance for ozone precursors. These thresholds are 10 tons per year for either of the following two ozone precursor emissions: reactive organic gases (ROG)or oxides of nitrogen (NOx). The District recommends the preparation of an Air Quality Impact Assessment (AQIA) and a Traffic Impact Study to determine impacts when projects are of this size, unless an analysis has been accomplished for a recent previous approval such as a general plan amendment or zone change. Please indicate to the District if the project has been analyzed and what the results were from any previous study. The ploW.racommends using ,jhe URQEMIS 2002 Version 8.7 program to calculate project area and opetatjdnal ainlis'lons and tp'Id9rit%y mitigMon medsures that'redud*6 impacts. URBEMIS can'be downloaded from www.urbemis.com or the South Coast Air Quality Management District's website at http://www.aqmd.gov/cega/urbemis.htmi. If the analysis reveals that the emissions generated by this project will exceed the District's thresholds, this project may significantly impact the ambient air quality if not sufficiently mitigated. The project applicant or consultant is encouraged to consult with District staff for assistance in determining appropriate methodology and model inputs. The District does not typically recommend quantifying PM10 emissions from construction activities. The District considers that PM10 emissions are reduced to levels considered less-than-significant through compliance with the District's Regulation VIII (Fugitive PM10 Prohibitions) rules. If construction activity is especially intense, or sensitive receptors are nearby, the District recommends applying the enhanced PM10 control measures listed in the Guide for Assessing and Mitigating Air Quality Impacts(GAMAQI). Based on the information provided, the proposed project will be subject to the following District rules. The following items are rules that have been adopted by the District to reduce emissions throughout the San Joaquin Valley, and are required. This project may be subject to additional District Rules. To Identify additional rules or regulations that apply to this project, or for further information, the applicant is strongly encouraged
