Deicing Products > Cryotech NAAC®
Commercial airports and military bases concerned with the quality of storm water run-off that may be contaminated by the use of urea can benefit from NAAC. If water drains directly from runways and taxiways into a body of water, NPDES discharge permits are required. These permits necessitate regular monitoring of run-off to determine certain characteristics, including BOD and nitrogen (ammonia) contamination. Urea's breakdown product - ammonia - is toxic to fish at very low concentrations.
Unlike urea, NAAC does not contain nitrogen and has a relatively low BOD. And since the EPA has given airports direction to evaluate the use of acetate deicers in lieu of urea (Federal Register 9/95), switching to NAAC may be considered a best management practice (BMP).
