In the early 1970s, environmentalists pointed to the fact that the Savannah River had been polluted by industrial waste and that an estimated 58% of Georgia's citizens lived in districts lacking adequate sewage treatment facilities. In 1972, at the prodding of Governor Jimmy Carter, the general assembly created the Environmental Protection Division (EPD) within the Department of Natural Resources (DNR). This agency administers 21 state environmental laws, most of them passed during the 1970s: the Water Quality Control Act, the Safe Drinking Water Act, the Groundwater Use Act, the Surface Water Allocation Act, the Air Quality Act, the Safe Dams Act, the Asbestos Safety Act, the Vehicle Inspection and Maintenance Act, the Hazardous Site Response Act, the Comprehensive Solid Waste Management Act, the Scrap Tire Amendment, the Underground Storage Tank Act, the Hazardous Waste Management Act, the Sedimentation and Erosion Control Act, the River Basin Management Plans, The Water Well Standards Act, the Oil and Hazardous Materials Spill Act, the Georgia Environmental Policy Act, the Surface Mining Act, and the Oil and Gas and the Deep Drilling Act. The EPD issues all the environmental permits, with the exception of those required by the Marshlands Protection and Shore Assistance Acts, which are enforced by the Coastal Resources Division of the DNR. Georgia's greatest environmental problems are an increasingly scarce water supply, nonpoint source water pollution, and hazardous waste sites. In 2003, the Environmental Protection Agency's database listed 408 hazardous waste sites, 14 of which were on the National Priorities List, in Georgia. As of 1997 the state had 7.7 million acres of wetlands. In 2001, Georgia received $66,447,000 in federal grants from the Environmental Protection Agency; EPA expenditures for procurement contracts in Georgia that year amounted to $24,113,000.
