State Stormwater RegulationBetween 1972, when the first Clean Water Act was passed, and 1990, about $260 billion in private and public funds was spent on wastewater treatment facilities. Another $20 billion, most of it from the public sector, was spent to comply with federal requirements on drinking water quality. The 1987 amendments to the Water Quality Act were the first concerted effort by the federal government to address pollution from non-point sources, including agricultural fields and feedlots, urban streets, and runoff channeled through municipal storm-water systems. The law required states to develop a non-point-source management plan. The 1987 act also created and funded several special programs, including one to deal with toxic hot spots and one to protect estuaries of national importance.

There are various regulations in place at the local, state and federal level for the management of stormwater and water quality. To review additional environmental legislation please visit the respective websites.

State Regulations

Pollution in our streams, lakes and rivers prevents these water bodies from meeting their water quality standards and designated uses regulated under the EPA's National Pollutant Discharge Elimination System (NPDES). For the State of Georgia the NPDES regulations are being administered by the Georgia Environmental Protection Division (EPD). Phase I of the NPDES (issued 1990) stormwater regulations were aimed at medium and large Municipal Separate Storm Sewer Systems (MS4s) with populations greater than 100,000 people. The Phase I regulations addressed discharges from regulated municipal, industrial, and certain construction activities.

Phase II of the NPDES Stormwater regulations (issued 1999) require that small MS4s (population less than 10,000) prepare and implement stormwater management plans to control pollution of stormwater from urbanized areas. Please visit the Watershed Protection Branch of the Georgia Environmental Protection Division (EPD) for a complete review of Georgia’s Environmental Rules and Laws.
