Dust Control
Answers to common questions about scheduling, services, the service area, and working with Gullwing.
Yes. Street sweeping and water truck services are recognized BMPs (Best Management Practices) under the NPDES general construction permit. Regular dust control and sweeping help contractors meet SWPPP requirements by reducing sediment and pollutant migration from the jobsite into storm drain systems.
Emergency and same-day service is available depending on location, crew availability, and conditions. Call (206) 960-3454 for availability.
Yes. Keeping public streets and site perimeters clean reduces the risk of corrective action during inspections. Route logs documenting when and where sweeping occurred support compliance records.
Yes. Wetting dirt surfaces near site entrances reduces the amount of material vehicles carry onto public streets. Combined with entrance sweeping, water application is one of the most effective track-out reduction strategies.
Emergency and same-day track-out cleanup is available depending on crew availability and site conditions. Track-out on public roads is one of the most common emergency service requests. Call (206) 960-3454 for availability.
Yes. Gullwing provides water truck services for construction sites throughout King, Snohomish, and Pierce counties.
Yes. Gullwing provides water truck support for dust suppression on active sites, dirt road and access road watering, track-out reduction at site entrances, and site preparation during dry weather. Learn more about water truck services.
Dust mitigation combines water application to suppress airborne particles, sweeping to remove deposited material, and site maintenance to address the conditions that generate dust. The approach is tailored to the source and site conditions.
Frequency depends on truck traffic volume, weather conditions, and site layout. High-traffic sites with unpaved entrances may need daily sweeping. Sites with stabilized construction entrances may need less frequent service.
Most construction projects with a SWPPP are required to implement dust control measures as part of their Best Management Practices. Dust mitigation supports these requirements and helps contractors avoid complaints and corrective action.
Yes. Water application for dust suppression is a recognized Best Management Practice under the NPDES general construction permit and supports SWPPP compliance goals.
Common sources include truck traffic on unpaved surfaces, excavation and grading, saw cutting, loading zones, exposed stockpiles, demolition, and dry weather conditions. Each source generates different particle sizes and volumes.
Construction dust control is the use of water application, sweeping, and site maintenance to reduce airborne dust, sediment migration, and debris movement on active construction sites. It is both a practical site management need (visibility, air quality, neighbor relations) and a regulatory requirement on most projects with a SWPPP.
Track-out is dirt, mud, sediment, or aggregate that construction vehicles carry from a jobsite onto public streets through the site entrance and exit points. It is one of the most common stormwater complaints on active construction projects.
Water trucks are most commonly needed during dry weather, heavy truck traffic, excavation, and any phase where dust or sediment migration is a concern for workers, neighbors, or stormwater systems.
