Hi Jenifer,

Thanks for reaching out on behalf of Paul. 
Washington County does not provide dust‑control treatment on private or non‑county‑maintained gravel roads. Their maintenance program focuses on county‑owned roads only. For private roads, residents typically hire a contractor to apply a dust‑control product.
For questions about whether Paul’s road is county‑maintained, he can contact:

• Washington County Department of Land Use & Transportation – Road Maintenance
  Phone: 503‑846‑7623
  Website: https://www.washingtoncountyor.gov/lut/road-maintenance

Where to Purchase - Paul will need to work with:

• A local road‑maintenance contractor, or
• A construction/industrial supply company that sells dust‑control products.

Washington County does not maintain a vendor list, but many rural contractors in western Oregon offer dust‑control services seasonally. Most dust‑control application is done by the same companies that:

• grade gravel roads
• haul rock
• do small‑scale excavation
• maintain private driveways

Look for companies that advertise:
road grading, gravel delivery, dust abatement, rural road maintenance



Can a landowner apply dust‑control products on their own gravel road?
Yes, as long as:

• The road is privately owned or privately maintained
• The product is legal for non‑commercial use
• The owner follows all label instructions (the label is the law)
• Application does not create runoff into streams, ditches, or wetlands

Most dust‑control products used in Oregon — like lignin sulfonate, magnesium chloride, and calcium chloride — are not restricted‑use pesticides, so a pesticide license is not required for personal use on one’s own property.
