(Rule 8031 Sec.5.0A) ❑ No bulk materials will be handled during this project. ❑ Water or dust suppressants will be applied when handling bulk materials. I ❑ Wind barriers with less than 50 percent porosity will be installed and maintained, and water or dust suppressants will be applied. r Outdoor Storage of Bulk Materials. (Rule 8031 See.5.0 B) I ❑ No bulk materials will be stored during this project. ❑ Water or dust suppressants will be applied to storage piles. ❑ Storage piles will be covered with tarps, plastic, or other suitable material and anchored in such a manner that prevents the cover from being removed by wind action. ❑ Wind barriers with less than 50 percent porosity will be installed and maintained around the storage piles, and water or dust suppressants will be applied. I ❑ A three-sided structure (< 50% porosity)will be used that is at least as high as the storage piles. On-Site Transporting of Bulk Materials. (Rule 8031 Sec.5.0 c) ❑ No bulk materials will be transported on the project site. ❑ Vehicle speed will be limited on the work site. ❑ All haul trucks will be loaded such that the freeboard is not less than six inches when transported across any paved public access road. ❑ A sufficient amount of water will be applied to the top of the load to limit visible dust emissions. ❑ Haul trucks will be covered with a tarp or other suitable cover. r Off-Site Transporting of Bulk Materials. (Rule 8031 Sec.5.0 0) I ❑ No bulk materials will be transported to or from the project site. ❑ The following practices will be performed: (complete Section 5-B) 7 • The interior of emptied truck cargo compartments will be cleaned or covered before leaving the site. • Spillage or loss of bulk materials from holes or other openings in the cargo compartment's floor, sides, and tailgates will be prevented. • Haul trucks will be covered with a tarp or other suitable cover or will be loaded such that the freeboard I is not less than six inches when transported on any paved public access road to or from the project site and a sufficient amount of water will be applied to the top of the load to limit visible dust emissions. Outdoor Transport using a Chute or Conveyor. (Rule 8031 Seo.5.0 E) ❑ No chutes or conveyors will be used. ❑ Chute or conveyor will be fully enclosed. ❑ Water spray equipment will be used to sufficiently wet the materials. ❑ Transported materials will be washed or screened to remove fines (PM10 or smaller). 3-F Comments i I I 10/14/2004
