These requirements include: <br />applying water as materials are handled, stabilizing or covering stored materials, and <br />installing wind barriers to limit VDE. Limiting vehicle speed, loading haul trucks with a <br />freeboard six inches or greater, covering haul trucks, or applying water to the top of the load <br />are options for reducing VDE from vehicle transportation of bulk materials. <br />Demolition. Wetting of the exterior of a building to be demolished is required. Demolition <br />debris and the area around the demolition must also be controlled to limit VDE. Cleaning <br />up carryout and trackout must be completed according to RUle 8041.

All sites subject to the regulation that employ dust control measures must <br />keep records for each day any dust controls are used.

The following exemptions in Rule 8021 apply to construction activities: <br />Blasting activities <br />Maintenance and remodeling of existing buildings if the addition is less than 50% of <br />the size of the existing building or 10,000 square feet. These activities, however, are <br />subject to the District's asbestos rule, Rule 4002. <br />Additions to single family dwellings <br />Mowing, disking or other weed control on sites less than 1/2 acre. <br />Nuisance. Whether or not the construction activity is exempt from the Regulation VIII <br />requirements, any activity that creates fugitive dust must not cause a nuisance, per Rule <br />4102 - Nuisance. Therefore, it is important to monitor the dust generating activities and, if <br />necessary, plan for and implement the appropriate dust control measures to limit the <br />public's exposure to fugitive dust. <br />This is a basic summary of Regulation Vill as it applies to the construction industry.
