De-icers
Green purchasing guidance for de-icers, including:
- Solid and liquid snow and ice melt products.
Required specifications
Purchasers must include these specifications, unless not possible:
- EO 20-01: State Efficiency and Environmental Performance (SEEP) states, “When making purchasing, construction, leasing, and other decisions that affect state government’s emissions of greenhouse gases (GHGs) or other toxic substances, agencies shall explicitly consider the benefits and costs (including the social costs of carbon) of available options to avoid those emissions. Where cost-effective and workable solutions are available that will reduce or eliminate emissions, decision makers shall select the lower-emissions options.”
It further states that “reducing… the use of dangerous toxics in the products state agencies purchase will all have a direct positive effect on human health, particularly for vulnerable children.”
Therefore, all packaged snow and ice melt products (including solids up to 50 pounds and liquids up to 55 gallons) must be free of sodium chloride AND either:- Certified by U.S. EPA’s Safer Choice Program
- On the Clear Roads Qualified Products List (QPL)
- All bulk liquid and solid deicers must contain a corrosion inhibitor.
