Tier2-4: Snow and Ice Removal

The KSC Grounds department uses a variety of techniques to reduce the environmental impacts of snow and ice. They use a professional weather service to get up to date and local condition information, ground temperature readings to determine the proper "product" to use and thoughtful and careful management of equipment. Ice Ban is a trademarked product, derived from brewer's wastes. It is significantly less toxic and less corrosive to plantings than salt. Where we do need to use salt, it is pretreated with the Ice Ban, making it much more effective and requiring significantly smaller amounts. The crew has developed techniques for pre-spraying roads and walkways before storms, since the Ice Ban works well as a pre-treatment, preventing the buildup of ice. We have eliminated the use of sand, which causes its own problems. Where possible, snow brooms are used to help clear snow, lessening damage to edge plantings. Each person in the Grounds department has assigned areas of responsibility in each season, including snow storm and storm clean up. This makes the vehicle use as efficient as possible, reducing redundancy and fuel use.
