Water Quality in Georgia
Georgia 305(b)/303(d) Integrated Report
Section 305(b) of the Clean Water Act requires States to assess its water quality every two years. To develop this report, Georgia compares water quality data collected across the State against our Water Quality Standards using the State’s Listing Assessment Methodology and places each water into one of three broad assessment categories; 1) supporting their designated use; 2) not supporting their designated use; or 3) assessment pending. Section 303(d) of the Clean Water Act requires States to submit a list of all waters that are not supporting their designated uses and need to have a Total Maximum Daily Load (TMDL) developed.
Georgia publishes the 305(b)/303(d) integrated report which is titled “Water Quality in Georgia”, the 305(b)/303(d) list of waters is found in Appendix A of this report. This list is organized by waterbody type (e.g. Rivers/Streams, Lakes/Reservoirs, etc.), provides the name, location, and assessment category. If the designated use is not being supported, causes of impairment are listed along with potential sources of pollutants.
Prioritization Framework for Georgia 303(d) Waters
US EPA has developed a Long-Term Vision for assessment, restoration, and protection of waters under the Clean Water Act Section 303(d) Program. This Vision focuses on six elements including 1) Prioritization, 2) Assessment, 3) Protection, 4) Alternatives, 5) Engagement and 6) Integration. In accordance with this Vision, GA EPD has developed a Draft Priority Framework that describes how GA EPD will prioritize waters on the 303(d) list for development of TMDLs or TMDL alternatives. EPD has prepared.
Guidance for Submitting Data For 305(b)/303(d) Integrated Report
Most data used to develop the 305(b)/303(d) list of waters is collected by the Georgia Environmental Protection Division, one of our sister agencies (Wildlife Resource Division, Coastal Resources Division, Parks and Historic Sites Division) or the USGS. Third parties such as local governments, universities, environmental groups, industries, etc. also submit data for use in development of the 305(b)/303(d) list. In accordance with Chapter 391-3-6-.03(13) of the Rules and Regulations for Water Quality Control, outside parties who wish to submit data for use in the 305(b)/303(d) listing process must submit and receive approval of a Sampling Quality Assurance Plan (SQAP). The purpose of this plan is to ensure that the data collected is of sufficient quality and quantity to make sound assessment decisions. Guidance for preparing a submitting a SQAP is provided below.
Deadlines for Submitting Data for Use in the 305(b)/303(d) Integrated Report
Asoliciting data for use in the development of the 2022 305(b)/303(d) list of waters was issued on February 9, 2021. Data are to be submitted by July 1, 2021. Details regarding requirements for submission of data can be found in the public notice.
