Dust Control Requirements

Dust from unpaved surfaces and dirt tracked onto paved surfaces contributes significantly to Spokane’s particulate matter (PM10) air pollution.

To reduce dust emissions, The Spokane Regional Clean Air Agency requires that dirt tracked onto paved surfaces be promptly removed and that reasonable measures be taken to control dust from unpaved areas.

These requirements (see Regulation I, Article VI, Section 6.05) apply to many different operations, such as construction, landscaping, and road work.

A guidebook, Controlling Dust in Spokane County, and a brochure, are available in hard copy format, by contacting The Spokane Regional Clean Air Agency.
