IKLEINF-ELDER Bright People.Right Solutions, Rules 8011-8081 are designed to reduce PM10 emissions (predominantly dust/dirt) generated by human activity, including construction and demolition activities, road construction, bulk materials storage, paved and unpaved roads, carryout and track out, landfill operations, etc. Rule 4101 (Visible Emissions) This rule prohibits emissions of visible air contaminants to the atmosphere and applies to any source operation that emits or may emit air contaminants. 1 Rule 4102 (Nuisance) Rule 4102 dictates that if a source operation emits or may emit air contaminants or other materials such that the emissions create a public nuisance, the owner/operator may be subject to SJVAPCD enforcement action. Rule 9510 (Indirect Source Review) Rule 9510, also known as Indirect Source Review (ISR), took effect March 1, 2006. The purpose of Rule 9510 is to reduce emissions of NOx and PM10 from new development in San Joaquin County including both construction and operational emissions. This rule requires specific percentage reductions in estimated project emissions for both construction and operation, or the payment of off-site mitigation fees if the required reductions cannot be met on the project site. The ISR rule applies to development projects that include: ® 50 residential units, ® 2,000 square feet (SF) of commercial space, ® 25,000 SF of industrial space, ® 20,000 SF of medical office space, ® 39,000 SF of general office space, ® 9,000 SF of educational space, 10,000 SF of government space, ® 20,000 SF of recreational space, or ® 9,000 SF of uncategorized space. The SJVAPCD has adopted its 2002 Guide for Assessing and Mitigating Air Quality Impacts (GAMAQI). GAMAQI defines analysis methodology, thresholds of significance, and mitigation measures for the assessment of air quality impacts. The methodology defined in GAMAQI was used in the analysis of this project. Under GAMAQI, project emissions for reactive organic gases (ROG) and nitrogen oxides (NOx) — the main ingredients in ozone - are significant if they exceed 10 tons per year. For PM10, the threshold is 15 tons per year. GAMAQI provides a three-tier framework for analysis of impacts regarding ozone precursor emissions, depending on project size. Small projects need no quantification of ozone precursors. The proposed project is considered a general light industrial activity. Under GAMAQI, a general light industrial activity with a project size of less than 510,000 square feet is considered a small project for analytical purposes. i 121339/ST011 R226 3-17 October 14, 2011 Copyright 2011 Kleinfelder
