#WE7201631 Wind Erosion Control
“Dust” is Particulate Matter (PM), solid particles which come primarily from the soil.
“Fugitive” dust is soil particulate matter that becomes airborne due to high wind and human activities; digging, grading, trenching, driving, rock crushing, utility line installation, or demolition. Fugitive dust can contain crystallized silica, asbestos fibers, and heavy metals.
Fugitive dust is also known to cause Valley Fever, which is a potentially serious illness caused by the inhalation of fungal spores that live in the top 2-12 inches of soil. In some cases, when soil is disturbed and inhaled by construction workers, fungal spores may duplicate in their lungs causing meningitis, a spine and brain infection that spreads to the rest of the body. If Valley Fever is not properly addressed, it can be fatal or the continuous inhalation of dust can cause asthma, bronchitis, and lung cancer.
Wind Erosion Control methods can keep your site in compliance and most BMPs that protect against water-based erosion also protect against wind-based erosion.
Wind Erosion Control Methods
- Preserving existing vegetation
- Applying water before conducting soil disturbing activities; clearing, grubbing, trucking
- Dust suppressing chemicals
- Soil binders, hydro-seeding, mulch, compost blanket, fiber based palliatives, salt and brines, non-petroleum based organics, petroleum based organics, synthetic polymers, and electrochemical products. All chemical dust suppression need to be environmentally benign and should not be used within 100 ft. of a body of water
- Covering large storage piles with visqueen and berming with gravel bags or fiber rolls
- Installing wind screens around the perimeter of a construction site
