relative to the use and storage of road salt.

HB 1607 prohibits storing road salt and de-icing chemicals (like sodium chloride) in ways that risk contaminating groundwater or surface water. It requires the Department of Environmental Services to create storage regulations, with stricter rules for areas already affected by chemical contamination. This directly affects local public works departments that store these chemicals for winter road maintenance. The bill establishes a regulatory framework but does not specify exact storage methods, leaving implementation to the department's future rules.
