III. ENVIRONMENTAL SETTING,IMPACTS AND MITIGATION MEASURES B. AIR QUALITY would incrementally add to regional atmospheric loading of ozone precursors during the short construction period. The SJVUAPCD GAMAQI recognizes that construction equipment emits ozone precursors,but indicates that such emissions are not considered to be significant unless the project construction is very large or very intense. Since project construction would be completed over a three-to six-month period and would not be considered to be a substantially large or intense construction project,construction-related emissions would be considered to be less than significant. Mitigation Measures Proposed as Part of the Project None. Mitigation Measures Identified in This Report Mitigation Measure B.1: Construction contractors shall implement a dust-abatement program that complies with the District's Regulation VIII Control Measures to reduce the contribution of project construction to local respirable particulate matter concentrations. This program shall include the following measures: • Water,chemical soil stabilizers/suppressants,or vegetative ground cover shall be used to control fugitive dust from all disturbed areas, including storage piles, which are not being actively used at the construction site. • Water or chemical soil stabilizers/suppressants shall be used to control fugitive dust from all unpaved roads on-site and all off-site unpaved access roads to the construction site. • Applications of water or presoaking shall be performed to control fugitive dust from all land clearing,grubbing,scraping, excavation,land leveling,grading,cut and fill, and demolition activities. • The exterior surfaces of buildings to be demolished shall be wetted during demolition. • Cover and wet all materials transported off-site or require all trucks to maintain at least six feet of freeboard from the top of the container. • Remove accumulated mud or dirt from adjacent public streets at least once every 24 hours during construction periods. (The use of dry rotary brushes is expressly prohibited,except where preceded or accompanied by sufficient wetting to limit the visible dust emissions. The use of blower devices is also expressly forbidden.) • Water or chemical soil stabilizers/suppressants shall be used to control fugitive dust after each addition of materials to or removal of materials from all storage piles. • Limit the speed of all construction vehicles to 15 miles per hour on unpaved roads. • Replant vegetation in disturbed areas as quickly as possible. Significance After Mitigation: Less than significant. Stockton Scavenger Transfer Station Expansion III.B.12 ESA 1990190
