Water all active construction areas at least twice daily, or as often as needed to control dust emissions. Watering should be sufficient to prevent airborne dust from leaving the site. Increased watering frequency may be necessary whenever wind speeds exceed 15 miles per hour. Reclaimed water should be used whenever possible. b. Pave, apply water twice daily or as often as necessary to control dust, or apply (non- toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas at construction sites.
