These measures shall be incorporated into the construction documents describing procedures and specifications for contractors to follow: • Water all active construction areas at least twice daily. • Cover all trucks hauling soil, sand, and other loose materials to or from the Project Area 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 mph. • Install sandbags or other erosion control measures to prevent silt runoff to public roadways. • Replant vegetation in disturbed areas as quickly as possible. • Suspend excavation and grading activities to the extent feasible when instantaneous wind gusts exceed 25 mph. • Limit, to the extent feasible, the number of areas adjacent to residences subject to excavation, grading and other construction activity at any one time. 9. Underground Service Alert. Prior to initiation of any on-site construction activities, the project developer shall contact the Underground Service Alert (USA) whose purpose is to receive planned excavation reports from public and private excavators and to transmit those planned excavation reports to all participating members of USA who may have underground facilities at the location of excavation. The USA will contact local utilities and inform them that construction is about to begin in their service area. This notice allows local utilities to mark the areas where their underground facilities are located near the construction site so that they may be avoided during project construction. 10. PG&E Gas Line. Prior to construction activities within 50 feet of the PG&E gas line, the project contractor shall identify and demarcate the location of the natural gas pipeline using highly visible markers that will remain in place throughout project construction in the vicinity of the pipeline and ensure that all construction workers are aware of the location of the line. The location of the pipeline shall be noted on the site and construction plans. Further, the 12
