03/27/2007 • Water or cover stockpiles of debris, soil, sand, or other materials that can be blown by the wind. • Cover all trucks hauling soil, sand, and other loose materials, or require all trucks to maintain at least two feet of freeboard. • Pave, apply water three times daily, or apply (non-toxic) soil .stabilizers on all unpaved access roads, parking areas, and staging areas at construction sites. • Sweep daily (with water sweepers) all paved access roads, parking areas, and staging areas at construction sites. • 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. • Install 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 bydiesel-powered 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 construction-related air quality impact significant level. these measures would reduce the of the Precise Plan to a less-than- 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 Atty/Reso/Reso.1683 29 14769 030707 Muff #613
