Draft Supplemental Environmental Impact Report Page IV.D-19 Forward Inc. Landfill 2018 Revised Project • All land clearing, grubbing, scraping,excavation, land leveling, grading, cut and fill, and demolition activities shall be effectively controlled utilizing application of water or by presoaking. • When materials are transported offsite, all material shall be covered, or effectively wetted to limit visible dust emissions, and at least six inches of freeboard space from the top of the container shall be maintained. • All operations shall limit or expeditiously remove the accumulation of mud or dirt from adjacent public streets at the end of each workday. However, the use of blower devices is expressly forbidden, and the use of dry rotary brushes is expressly prohibited except where preceded or accompanied by sufficient wetting to limit the visible dust emissions. • Following the addition of materials to, or the removal of materials from, the surface of outdoor storage piles,said piles shall be effectively stabilized utilizing sufficient water or chemical stabilizer/suppressant. • Any site with 150 or more vehicle trips per day shall prevent carryout and trackout. Enhanced and additional control measures for construction emissions of PM10 shall be implemented where feasible. These measures include: • Limit traffic speeds on unpaved roads to 15 mph by signage and electronic speed monitoring devices. • Install sandbags or other erosion control measures to prevent silt runoff to public roadways from sites with a slope greater than one percent. • Install wheel washers for all exiting trucks, or wash off all trucks and equipment leaving the site. • Install wind breaks at windward side(s)of construction areas. • Suspend excavation and grading activity when winds exceed 20 mph. • Limit area subject to excavation, grading, and other construction activity at any one time. The applicant shall implement feasible control measures during construction to mitigate NO,, and VOC emissions from construction equipment,which may include: • Require construction equipment used at the site to be equipped with catalysts/particulate traps to reduce particulate emissions. These catalysts/traps require the use of ultra-low sulfur diesel fuel(15 ppm). Currently, CARB has verified a limited number of these devices for installation in several diesel engine families to reduce particulate emissions. At the time bids are made, contractors must show that the construction equipment used is equipped with particulate filters and/or catalysts or prove why it is infeasible. • Use alternative fueled construction equipment,where feasible. • Replace fossil-fueled equipment with electrically driven equivalents (provided they are not run via a portable generator set).
