HB 1478 requires New Hampshire's Department of Environmental Services to revise rules for new landfills to better protect public health and the environment. The bill mandates that new landfills must maintain a minimum 1,500-foot setback from drinking water wells, rivers, lakes, and coastal waters, calculated using a specific groundwater travel distance method. This method requires applicants to hire independent hydrogeologists to test groundwater velocity and ensure contamination cannot reach water sources within five years. The rule changes directly affect landfill applicants and the Department, replacing current rules deemed insufficiently protective of water resources.
