MR QUALITY !Section 4.61 SIGNIFICANT EFFECT Impact 4.6-1: Construction-Related Air Emissions. Construction activities associated with the proposed Specific Plan would temporarily produce emissions of NOx,ROG, SO?, CO, and PML0. Emissions would vary substantially from day to day and could potentially produce substantial amounts of PML0. The generation of these construction emissions on the project site would be considered a short-term potentially significant air quality impact. Changes or alterations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the environment. Facts in Support of Finding The City of Pleasanton has adopted the following measures which will reduce potential air quality impacts to a less-than-significant level: Mitigation Measure 4.6-1: Construction-Related Air Emissions. Site grading, excavation, and general construction activities could result in temporarily significant air quality impacts. To mitigate this impact, the Specific Plan air quality mitigation measures shall be implemented at all construction sites in accordance with Bay Area Air Quality Management District (BAAQMD) Basic and Enhanced Control Measures. The specific controls included in the Specific Plan are as follows: · During the construction period, all active unpaved construction areas shall be watered at least twice daily or treated with non-toxic soil stabilizers in order to avoid dust. Exposed stockpiles of dirt or sand shall be enclosed, covered, watered twice daily, or treated with non-toxic soil binders. · If soil material is carried on public or private roads, such roads shall be swept daily with water sweepers to control dust, where applicable. · In graded construction area, replacement vegetation shall be planted as quickly as possible. Graded areas that remain inactive for ten days or more during the rainy season (i.e., October 1 to April 1) without permanent replanting should be hydro seeded or stabilized to inhibit dust. · All trucks hauling excavated materials shall be covered with tarpaulins or other effective covers. · All unpaved access roads, parking areas, and staging areas at construction sites shall be paved, watered three times daily, or covered with non-toxic soil stabilizers. · Traffic speed on unpaved roads shall be limited to 15 miles per hour. · Reactive organic gas (ROG) emissions from adhesives, clean-up solvents, paint, and asphalt paving materials used during project construction shall be reduced by using materials with a low ROG content, in compliance with Bay Area Air Quality Management District standards.
