Idaho Environmental Guide for Local Governments: Fugitive Dust
Dust is particulate matter consisting of very small particles. Fugitive dust is particulate matter suspended in the air.
Why Communities Should Care
According to the Rules for the Control of Air Pollution in Idaho (IDAPA 58.01.01, Section 651), reasonable precautions must be taken to prevent particulate matter from becoming airborne.
Communities experiencing population growth may experience a rise in fugitive dust emissions as parcels of land are cleared of vegetation for development, construction, and excavation activities, and dirt and gravel roads are constructed. These activities expose and disturb soil and create fugitive dust, which can contribute to health problems and affect visibility on local roads.
Cities and counties are responsible for complying with the fugitive dust rules on city and county property. Examples of reasonable precautions may include, but are not limited to, paving high-traffic dirt roads, sweeping roadways often, or using wind erosion controls such as planting bushes or trees or constructing wood or rock walls in dusty areas.
What Communities Can Do
- Prior to project approval, request that project information specify which requirements under Rules for the Control of Air Pollution in Idaho (IDAPA 58.01.01, Section 651) apply.
- Plan ahead by incorporating dust management into your comprehensive plan. Keeping potential fugitive dust problems under control is an everyday job.
- Understand how a project may emit dust and consider requiring such projects within your jurisdiction to develop dust prevention and control plans prior to approval. Dust prevention and control plans incorporate appropriate best management practices to control fugitive dust that may be generated at sites.
- Local governments have the authority to implement ordinances that help prevent fugitive dust emissions beyond state and federal laws and regulations (such as requiring open-bodied haul trucks transporting dusty material be covered). Determine what is best for the health and welfare of the community.
