1. Purpose
This Dust Mitigation Plan establishes procedures to minimize airborne dust and particulate matter generated
during construction activities. The goal is to protect worker health, maintain public safety, comply with local air
quality regulations, and prevent nuisance conditions to surrounding properties.
2. Scope
This plan applies to all phases of construction including:
• Site clearing and grading
• Excavation and trenching
• Material stockpiling
• Concrete cutting and demolition
• Truck hauling and equipment operation
• Landscaping and final site work
3. Responsible Parties
Primary Responsibility:
• Site Superintendent/Project Manager
Supporting Roles:
• Safety Officer
• Subcontractor Foremen
• Equipment Operators
All subcontractors must comply with this plan as a condition of site access.
4. Dust Control Measures
4.1 Water Application
• Apply water to exposed soil areas as needed to prevent visible dust emissions.
• Increase watering frequency during dry, windy, or high-traffic conditions.
• Use water trucks, hoses, or automated sprinkler systems where practical.
• Avoid overwatering that could create runoff or erosion.
4.2 Soil Stabilization
• Apply temporary soil stabilizers, mulch, or tackifiers on inactive areas exceeding 7 days.
• Use gravel,base material, or matting on high-traffic access routes.
• Permanently stabilize disturbed areas with pavement, landscaping, or vegetation as soon as practical.
4.3 Vehicle and Equipment Controls
• Enforce on-site speed limits (maximum 15 mph on unpaved surfaces).
• Minimize unnecessary vehicle travel on exposed soils.
• Shut down idling equipment when not in active use.
• Use designated haul routes.
4.4 Track-Out Prevention
• Install stabilized construction entrances using aggregate pads.
• Sweep paved roads daily or as needed to remove tracked soil.
• Use rumble strips or wheel wash stations if required by local regulations.
4.5 Material Handling
• Cover or tarp haul trucks transporting soil or debris.
• Wet down materials during loading and unloading operations.
• Place stockpiles away from site boundaries and sensitive receptors.
4.6 Demolition and Cutting Activities
• Use water spray or misting during concrete cutting, drilling, or demolition.
• Use vacuum attachments on saws when feasible.
• Schedule high-dust activities during low-wind conditions when possible.
5. Weather Monitoring
Monitor daily weather conditions and wind speeds.
• Suspend or modify dust-generating activities during high-wind events (typically>20 mph or per local
ordinance).
• Increase mitigation efforts during dry weather periods.
6. Inspection and Maintenance
• Conduct daily visual inspections of dust control measures.
• Document corrective actions when visible dust is observed.
• Repair damaged controls immediately.
• Maintain water trucks, hoses, and spray equipment in proper working condition.
7. Complaint Response Procedure
If a dust-related complaint is received:
1. Immediately investigate the source.
2. Implement corrective measures (additional watering, work suspension, material covering).
3. Document the complaint and resolution.
4. Adjust procedures to prevent recurrence.
8. Training and Communication
• Provide dust control training to site supervisors and equipment operators.
• Conduct toolbox talks addressing dust prevention.
• Post speed limit and dust control signage at site entrances.
9. Regulatory Compliance
All activities will comply with:
• Local Air Quality Management District(AQMD) requirements
• State environmental regulations
• OSHA worker exposure standards
• Project permit conditions
10. Emergency Response
In the event of uncontrolled dust emissions:
• Stop dust-generating work immediately.
• Apply water or stabilizers.
• Notify site management.
• Resume work only after conditions are controlled.
SWPPP Integration - Fugitive Dust Control Plan
1. BMP Category: Air Quality / Fugitive Dust Control
Dust control measures will be implemented to prevent off-site migration of particulate matter and to reduce
potential water quality impacts associated with airborne sediment settling into stormwater conveyances.
2. Applicable Construction Activities
Dust-generating activities include but are not limited to:
• Clearing and grubbing
• Mass grading and excavation
• Trenching and utility installation
• Demolition and concrete cutting
• Haul truck operations
• Stockpiling and material handling
• Final grading and landscaping
3. Best Management Practices (BMPs)
3.1 Watering and Moisture Control
• Apply water to exposed soils as needed to prevent visible dust emissions.
• Increase application frequency during dry or windy conditions.
• Use water trucks, spray hoses, or fixed sprinkler systems where appropriate.
• Prevent overwatering to avoid runoff and erosion.
3.2 Soil Stabilization
• Apply temporary stabilization(mulch, soil binders, gravel, or tackifiers) to inactive disturbed areas
exceeding 7-14 days (or per local permit requirements).
• Permanently stabilize areas as soon as final grades are achieved using vegetation,pavement, or other
approved methods.
3.3 Construction Entrance and Track-Out Control
• Install stabilized construction entrances with aggregate pads to minimize sediment and dust tracking.
• Inspect entrances daily and replenish aggregate as needed.
• Sweep adjacent paved roads daily or as needed.
3.4 Vehicle Controls
• Enforce a maximum speed limit of 15 mph on unpaved surfaces.
• Restrict unnecessary vehicle traffic on disturbed areas.
• Use designated haul routes when possible.
3.5 Stockpile Management
• Locate soil stockpiles away from drainage paths and site boundaries.
• Cover stockpiles or apply soil binders when inactive.
• Wet stockpiles during windy conditions.
3.6 Demolition and Material Handling Controls
• Apply water spray during demolition, saw cutting, and material transfer.
• Cover haul trucks transporting soil or debris.
• Stage dusty operations away from storm drain inlets when feasible.
4. Inspection and Monitoring
Dust control BMPs will be inspected:
• Daily during active construction
• Weekly as part of SWPPP inspections
• Before forecasted high wind events
• After complaints or visible dust emissions
Inspection findings and corrective actions will be documented in SWPPP inspection logs.
5. Corrective Action Procedures
If visible dust emissions occur:
1. Stop or reduce dust-generating activity.
2. Apply water or stabilization methods immediately.
3. Install additional BMPs if needed.
4. Document corrective action in SWPPP records.
5. Resume work only after dust is controlled.
6. Training Requirements
All site personnel will receive training on:
• Dust control BMP implementation
• Proper watering and stabilization techniques
• Equipment operation speed limits
• Reporting uncontrolled dust emissions
Training records will be maintained with the SWPPP.
7. Recordkeeping
The following documentation will be maintained onsite:
• Daily watering logs (if required by permit)
• Weekly SWPPP inspection reports
• BMP maintenance records
• Dust complaint logs and response actions
8. Regulatory Compliance
Fugitive dust control measures will comply with:
• Construction General Permit (CGP)requirements
• Local Air Quality Management District(AQMD) rules
• Municipal stormwater permits
• Project-specific permit conditions
