Caption

Map of U.S. wastewater treatment facilities with general permits (orange) intended to cover multiple dischargers engaged in similar activities and individual permits (blue) that cover a specific facility. Individual states assign the permits based on different classifications. A national regulatory initiative to reduce pollution in waterways would not apply to general permits initially, leaving out approximately 40 percent of all wastewater treatment facilities.
