New Hampshire Salt Reduction BMP Development

We are in the process of updating our website.  Please contact t2.center@unh.edu to access Best Management Practices documents on any of the below topics.  These Best Management Practices (BMP) have been assembled as the result of a multi-year survey of the best and most applicable technology for New Hampshire Snow & Ice Management Professions. These documents have been reviewed by NHDES, NHDOT, FHWA, EPA and several New Hampshire communities including: Derry, Salem, Londonderry, and Windham.  We are pleased to share this information with you upon request, as well as provide additional information to support salt reduction programs.
