LFR Levine-Fricke • All land clearing, grubbing, scraping, excavation, land leveling, grading, cut and fill, and demolition activities shall have fugitive dust emissions effectively stabilized utilizing water application or by presoaking. • When materials are transported off site, all material shall be effectively wetted and covered to limit visible dust emissions, or at least 6 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 least once a month when operations are occurring. The use of dry rotary brushes should be limited 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 have fugitive dust emissions effectively stabilized using sufficient water or chemical stabilizer/suppressant. • Traffic speeds on unpaved roads shall not exceed 15 mph. • To the extent feasible, the area subject to excavation, grading, and other construction activity at any one time will be limited. The following measures will be implemented as part of the proposed project to reduce the impacts of ozone precursor emissions from construction equipment exhaust. • When feasible, use alternative fuel construction equipment. • Minimize idling time to a maximum of 10 minutes when construction equipment is not in use. • To the extent practicable, minimize operation of heavy-duty equipment to reduce emissions. • When feasible, use low-emission on-site station equipment. With implementation of these measures,particulate emissions from fugitive dust and construction emissions during sediment excavation and removal activities will be reduced to a less-than-significant level. Formatted:Bullets and Numbering Biological Resources The following conservation measures will be implemented as part of the proposed project to avoid impacts to special status animal species having the potential to occur in the project area: • Project activities shall be performed during daylight hours. • Vehicles moving around the project site, including trucks and excavators, will remain to the fullest extent possible on existing access roads. In the event that a vehicle must travel off road to excavate existing burn piles, a qualified biologist will examine off-road areas to ascertain the best route to the burn piles.
