Stormwater: What's Being Done
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) .
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
- Public Education and Outreach:
Distribute educational material and perform outreach to
inform citizens on how to control and manage stormwater
runoff and reduce pollution
- Public Participation/Involvement:
Provide opportunities for the to public participate in the
development and implementation of stormwater initiatives.
- Illicit Discharge Detection
and Elimination: Develop and implement a plan to
detect and eliminate unauthorized discharges to the municipal
separate storm (sewer) system.
- Construction Site Runoff
Control: Develop, implement and enforce a sediment
and erosion control program for construction activities.
- Post-Construction Runoff
Control: Develop, implement, and enforce a program
to address discharges of post-construction runoff and specify
appropriate stormwater control practices.
- 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).
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.
