Stormwater: What's Being Done

When It Rains It DrainsThe National Pollutant Discharge Elimination System (NPDES) program was established under the authority of the Clean Water Act. Phase II of the NPDES stormwater program was signed into law in December 1999. This regulation builds upon the existing Phase I program, developed in 1990, by requiring smaller Phase II communities to permit the small municipal separate storm sewer systems (MS4s) Adobe Acrobat PDF.

Stormwater Phase II Permit Compliance

Henry County is required by law to comply with the U.S. Environmental Protection Agency's Stormwater NPDES Phase II Permit Program. This program requires that all regulated communities, including Henry County, prepare stormwater management plans to control pollution of stormwater from both Point and Non-point sources of pollution in urbanized area.

In an effort to be a good steward in the preservation of water quality and comply with numerous regulations Henry County is taking a proactive approach to stormwater management. Some of the activities presently underway for watershed protection and stormwater management include:

  • NPDES Stormwater Phase II Permit Compliance
  • Greenspace Program
  • Watershed Assessment
  • Conservation Subdivision Ordinance

The requirements of stormwater management also contain six minimum control measures. The control measures are referred to as Best Management Practices (BMPs). The Best Management Practices are structured to ensure compliance with the NPDES Permit and promote all six of the BMP measures that address pollutant load reduction.

The requirements of the program include the following:
Best Management Practices (BMPs) for the following six minimum control measures:

  1. Public Education and Outreach: Distribute educational material and perform outreach to inform citizens on how to control and manage stormwater runoff and reduce pollution
  2. Public Participation/Involvement: Provide opportunities for the to public participate in the development and implementation of stormwater initiatives.
  3. Illicit Discharge Detection and Elimination: Develop and implement a plan to detect and eliminate unauthorized discharges to the municipal separate storm (sewer) system.
  4. Construction Site Runoff Control: Develop, implement and enforce a sediment and erosion control program for construction activities.
  5. Post-Construction Runoff Control: Develop, implement, and enforce a program to address discharges of post-construction runoff and specify appropriate stormwater control practices.
  6. Pollution Prevention/Good Housekeeping for Municipal Operations: Develop and implement a program to educate and train municipalities on operations and practices the will reduce pollutant to the municipal separate stormwater sewer system (MS4).

Watershed Assessment

The Henry County Water and Sewerage Authority (HCWSA) has conducted a comprehensive watershed assessment for all major watersheds in the county. The assessment included field studies at more than 30 sites along streams in the county to evaluate water quality and biological conditions and to determine whether the streams meet the Georgia Environmental Protection Division's water quality standards and designated uses. Along with other analyses, the watershed assessment has studied and determined which streams are impacted and to what extent.

A watershed management plan has been developed to address these impaired streams and to implement proactive measures to prevent these problems from occurring in other areas of Henry County. Early in 2007, the Henry County Board of Commissioners modified the development standards and regulations to help address these same issues.

Henry County is part of the Upper Ocmulgee Watershed. You can use the following links to view GIS maps of watersheds and critical water areas within Henry County.
