Hacienda TOD Standards and Design Guidelines Initial Study ambient air quality conditions, and because the presence of pollution detracts from the recreational experience. Significance Criteria The impact questions above constitute the significance criteria for this environmental topic. Also, the significance criteria related to question 3b) are further explained below. The significance criteria established by the Bay Arca Air quality Management District (BAAQMD) is used to determine the significance of air quality impacts. A project would have a significant impact on air quality if the proposed project and uses would cause total criteria air pollutant emissions (i.e., from both stationary and mobile sources) to equal or exceed the following BAAQMD- defined thresholds: Reactive organics 541bs /day Nitrogen oxides 54 lbs/day Particulate matter (PIM 82 lbs /day According to the RA 101LID Guidelines, a project that would individually have a significant air quality impact would also be considered to have a significant cumulative air quality impact. No regulatory agency has adopted standards of significance with regard to toxic air emissions from mobile sources. Future residential development projects located within 1,000 feet of a heavily travelled street or freeway would need to analyze the long -term health risks of locating homes in this location. Greenhouse gas emissions are discussed in Section. X.X. of this initial study. Discussion of Checklist Items Less - than - Significant Impacts. Currently the City is in compliance with State and federal carbon monoxide standards. In the future, carbon monoxide emission rates from motor vehicles are expected to decline from their present Average values resulting in lower future carbon monoxide emissions. Future cumulative development in Alameda County would drop about 72 percent from 2005 to 2025, as shown on Table 1, below. Even with increased development in the Bay Area and in Pleasanton, carbon monoxide emission rates would also be expected to drop. Development impacts resulting from this proposed zoning change have been considered in this cumulative total.
