Dust Control Evaluation Summary
October 11,2001
4
• Effectiveness for controlling dust
• Difficulty of handling and application.
• Rate of curing.
• Application rate and frequency.
• Performance in cold temperatures.
• Worker exposure.
• Cost effectiveness.
Pilot testing with lignin derivatives, salts, and beet oil are recommended for the roadway.
Pilot testing with surfactants, highly purified bitumen products, and lignin derivatives is
recommended for the stock piles and debris handling and sorting areas. Pilot testing of
5 to 6 products can probably be conducted for $20,000 to $30,000.
Furthermore, EE&G recommends the following dust control activities continue to be
implemented for dust control until alternative means are implemented:
• Periodic watering of all roads (paved and unpaved) in the iandfiil faciiity.
• Periodic watering segregation and inspection eras where manual debris
sorting is conducted.
• Inspect and verify that debris scheduled for off-loading from the barges has
been watered to minimize dust If not. It should be watered before unloading
I from the barge.
I
I • Water truck misting of dusty areas around the active debris sorting operation.
I
I • Continue to enforce site speed limit of 5 miles per hour to minimize dust
I generation.
I
I • Maintain pro-active management of all watering by conducting frequent
inspections and watering before dust generation becomes significantly
visible.
