NYC 9/11 Public Portal Document Dust Control Evaluation Summary October 11, 2001

• Soybean oil. e Adhesives, including lignin derivative, tree resin emulsions, and synthetic polymer emulsions, which bind particles together. e Foams that encapsulate particles with minimum moisture addition.

Chemical dust suppressants are typically applied by mobile and/or stationary equipment, using spray nozzles. Chemical dust suppressants may be applied to roadways, existing I debris stock piles, and other work areas. It is likely that different chemical dust suppressants may be appropriate for different application. I I ALTERNATIVES COMPARISON
