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 variety of literature is available:
Spokane County coordinates a Road Improvement District (RID) program, allowing property owners a way to upgrade their dirt road while improving their neighborhood, air quality and property value. Two brochures are available for download; RID and RID Assessments. For more information on RIDs, visit Spokane County's website.
The City of Spokane coordinates a Local Improvement District (LID) program, allowing property owners within neighborhoods a way to improve their community, such as paving roads, alleys and lighting upgrades.
