ATLANTA — Environmental regulators in Georgia would have to consult with local officials on how best to handle toxic spills under a proposal backed by House lawmakers. The legislation, approved by a house committee Monday, requires the Environmental Protection Division to develop plans with local officials on how they would respond to chemical spills in waterways after several spills called into question the state's emergency response system and whether local officials were prepared to deal with chemical hazards in their cities and towns. It also makes it tougher for state officials to trim funding for the emergency response wing of the EPD, which saw spending cutbacks after the last recession.
