Water Quality Trading

Restoring and preventing water quality degradation is a difficult ecological, economic, and regulatory challenge that requires states and communities to rely on a diverse set of tools and strategies. Water quality trading is one tool that can be used to protect, maintain, and restore Georgia’s waterways. Water quality trading enables facilities to buy and sell pollutant reduction credits for reductions beyond water quality-based effluent limitations (WQBELs) and gives nonpoint sources the opportunity to be compensated for reductions beyond those already required by law or regulation. These credits can be purchased by an entity to achieve less costly pollutant reduction than if the entity acted alone. Trading ultimately provides an equal or greater water quality benefit to the receiving water, as measured by pollutant load reductions. EPD has developed a water quality trading guidance document  to provide information about how water quality trading can be implemented in Georgia.

This guidance document is the result of an extensive public process, including a stakeholder process  held on a general trading framework  in 2019 and a stakeholder process held on a draft guidance document in 2021. EPD received many comments during the 2021 stakeholder process, which resulted in several changes to the guidance document before finalization. A summary of that stakeholder process and a response to those comments can be found here  .
