NHDOT project development policy necessitates that all properties potentially affected by design projects be screened for hazardous materials (hazmat) issues, and that this screening be performed as early as possible in project planning to maximize the time available for assessment of contamination and to allow for the incorporation of this data into purchasing decisions, route selection, construction planning, and health & safety plan preparation. The RASCAL program assists in the collection and management of the information required by this policy. To request access to this database please contact Kevin Nyhan -
