7A Page 46 • Sweep streets daily (with water sweepers) if visible soil material is carried onto adjacent public streets. • Hydroseed or apply (non-toxic) soil stabilizers to inactive construction areas (previously graded areas inactive for ten days or more). • Enclose, cover, water twice daily, or apply (non-toxic) soil binders to exposed stockpiles (dirt, sand, etc.). • Limit traffic speeds on unpaved roads to 15 miles per hour. • Instal! sandbags or other erosion control measures to prevent silt runoff to public roadways. • Replant vegetation in disturbed areas as quickly as possible. • Consult with BAAQMD prior to demolition of structures suspected to contain asbestos to ensure that demolition/construction work is conducted in accordance with BAAQMD rules and regulations. The following are measures to control emissions by diesel-porr~ered construction equipment used by construction contractors, where applicable: • Ensure that emissions from all on-site, diesel-powered construction equipment do not exceed 40 percent opacity for more than three minutes in any one hour. Any equipment found to exceed 40 percent opacity (or Ringelmann 2.0} shall be repaired or replaced immediately. • The contractor shall install temporary electrical service whenever possible to avoid the need for independently powered equipment (e.g., compressors). • Diesel equipment standing idle for more than three minutes shall be turned off. This would include trucks waiting to deliver or receive soil, aggregate, or other bulk materials. Rotating drum concrete trucks could keep their engines running continuously as long as they were on-site and away from residences. • Properly tune and maintain equipment for low emissions. Finding: Implementation of these measures would reduce the construction-related air quality impact of the Precise Plan to a less-than- significantlevel. Impact 12-2: Long-Term Regional Emissions Increases. Development in accordance with the proposed Downtown Precise Plan under both the Maximum Intensity and Moderate Intensity alternatives would generate traffic- related regional air pollutant emissions increases that would exceed the applicable thresholds of significance for reactive organic gases (ROG), nitrous oxide (NOx), and particulate matter (PM10). This Precise Plan-related effect is considered to represent a significant project and cumulative impact (see criteria 1,2,3,4, and 7 in subsection 12.3.1, "Significance Criteria, "above}. Mitigation 12-2. Apply the following emissions control strategies where applicable to Precise Plan-facilitated discretionary mixed use, residential, office, retail, and lodging development activities within the proposed Pfan area in order to reduce overall emissions from traffic and area sources: Atty/Resa/Reso.1683 29 030707
