Vegetable oil a no-no for most dust control

The in basket: Neil Streicher asks, “We live on a community gravel road and looking for a way to control dust from the road that is environmentally safe and want to know if vegetable is approved for this purpose.

“Unable to find a government agency with an answer,”

he said.

The out basket: I asked Kitsap County Public Works Neil’s question and spokesman Doug Bear says he found the following about using vegetable oil for dust control:

“The Washington State Department of Ecology would consider that an illicit discharge if it were to enter anything they consider ‘waters of the State,’ including wetlands, ponds, creeks, etc. as well as Puget Sound.  That’s specified by the Clean Water Act.  See here:  https://www.epa.gov/sites/production/files/2015-06/documents/clean_water_rule_40_cfr_230_3.pdf

“Per (the county’s) stormwater permit, issued by the state, we have to consider anything entering our system an illicit discharge unless it’s straight stormwater, or any of the ‘allowable discharges’ listed on pages 20 and 21 here: http://www.ecy.wa.gov/programs/wq/stormwater/municipal/phaseIIww/5YR/2014mod/WWAPhaseII-Permit-2014Final.pdf

You can look it up it you like. It’s specific  to municipalities but will give you an idea of the detail included in the clean water laws.

Doug continued, “We generally use water as our preferred dust-control method, but there are also commercial products available that are plant-lingin based binders that can be applied. These typically require a professional to apply. and they may not hold up to frequent traffic.”
