For many years, the Qualified Products List (QPL) maintained by the Pacific Northwest Snowfighters association has served as a resource for agencies across the country, identifying deicing chemicals and additives that meet established standards for corrosiveness and impact on the environment. As the QPL continues to grow, Clear Roads will be overseeing the product testing and administration for the list, which is now called the Clear Roads QPL. For an updated version of the CR QPL and a Letter to Vendors about the transition, visit the Clear Roads QPL page.
