The source of this information is from a booklet titled “Air Quality Conservation Management Practices for San Joaquin Valley Farms” and was developed in cooperation with the Agriculture Improving Resources (AIR) partners, the USDA Natural Resources Conservation Service, the San Joaquin Valley Region of the California Association of Resource Conservation Districts, and the San Joaquin Valley Air Pollution Control District.  You may view the booklet on-line by visiting the California Cotton Ginners and Growers Association web site and clicking here.  [The file is quite large and may take a few minutes to download].

The products and brand names mentioned below are for informational purposes only and should not be considered a complete listing of all the available products, nor as an endorsement of any of the products listed. 

Per Rule 8011 – General Requirements, any chemical or organic material used for stabilizing solids shall not violate State Water Quality Control Board standards for use as a soil stabilizer.  Any material prohibited for use as a dust suppressant by the US Environmental Protection Agency, the California Air Resources Board, or other applicable law, rule, or regulation is also prohibited under Regulation VIII.  Hydroscopic materials may be prohibited in areas lacking sufficient atmospheric moisture of soil for such materials to effectively reduce fugitive dust emissions.  The atmospheric moisture of soil is considered to be sufficient if it meets the application specifications of the hygroscopic product manufacturer.  Use of such materials may be approved in conjunction with sufficient wetting of the controlled area.

Table 1:  The suppressant categories listed below have been found to meet the 50 percent PM10 control for a Fugitive PM10 Management Plan.  In addition, these products may be effective in limiting visible dust emissions and maintaining a stabilized unpaved road surface.
