San Joaquin valley Air Pollution Control District COMPLIANCE ASSISTANCE BULLETIN September 2002 (Update from June 2002) Fugitive Dust Control at Construction. Sites Regulation.VIN, Fugitive 13111110. Prohibitions, of the District's Rules and Regulations regulates activities.that generate fugitive dust. Fugitive dust is emitted to the air from open ground or caused by activities such as excavation, transportingbulk materials, or travel on unpaged surfaces. "PM.10" is a term applied to small,sized particulate matter- microscopic dust particles - in the air. The Ban Joaquin Valley currently exceeds the air quality standards for particulate matter. Itis for this'reason that the District adopted Regulation Vill in 1993. Significant amendments`to Regulation.Vlfl were adopted in 2001 and became effective May 15, 2002.:The following dust control and administrative requirements are applicable at construction sites: Visible Dust Emissions. (VDE). Visible.dust.emissions may not exceed 20% opacity . during periods when soil.is tieing disturbed byequipment or wind at anytime. gust control. may be achieved by means.of applying water before and during earth work and on traffic areas, phasing work to limit.dust, and setting upwhd fences to limit wind blown dust. VDE opacity of 20% means the amount of dust that would obstruct the view of an object by 206/9. Soil stabilization. Soil stabilization is required at any construction site after normal working hours and on weekends and holidays. This requirement also applies to inactive construction areas such as phased projects where disturbed land is left unattended.. Applying water to form a visible crust on the soil is an effective method for stabilizing a disturbed surface area. Long-term.methods include applying dust suppressants or establishing vegetative cover. Restricting vehicle access from,the area will help to maintain a stabilized surface. Information regarding stabilization standards and test methods are in Rule 8011 General Requirements. Carryout and Trackout. These requirements are found in Rule 8041 — Carryout and Trackout: Carryout and trackout are'rnaterials adhered to vehicle tires and transport vehicles carried from a construction site and deposited onto a paved public road. Should carryout and trackout occur, it must be cleaned up at least daily, and immediately,if it extends more than 50 feet from the exit point onto a paved road. The recommended clean- up methods include manually sweeping, sufficiently wetting the area prior to mechanical sweeping to limit VDE or using a PM10-efficient street sweeper. A blower device, or dry sweeping with any mechanical device other than a PM10-efficient street sweeper is prohibited.
