This chapter presents information on strategies used to reduce the impacts of snow and ice control materials once they are introduced from the roadway into the surrounding environment. Commonly used techniques consist of the implementation of structural Best Management Practices (BMPs), which comprise reactive measures implemented along roadsides or near sensitive water sources to capture abrasives and treat deicer‐laden stormwater runoff. Due to the highly mobile nature of chlorides, increased chloride concentrations in the environment associated with roadway deicers pose a significant environmental concern and the use of traditional BMPs often fails to be effective in managing chlorides. This chapter provides an overview of using stormwater structural BMPs for management of suspended solids and chlorides, followed by a summary of criteria for BMP selection and alternative approaches to chloride removal. Subsequently, methods for cleanup and recycling of winter maintenance abrasives are discussed, followed by methods for recycling of salt brine.
