Water quality trading (WQT) is an innovative, market-based, cost-effective mechanism to help achieve local water quality improvements (EPA, 2003). In WQT, sources with high costs of reducing pollution can purchase equal or greater pollution reductions from sources with lower costs. This cost difference provides an incentive for trading to occur.
WQT Program in Louisiana
LDEQ developed a WQT program, supported by state legislation and consistent with the Clean Water Act, and state and federal law, to facilitate trading among watershed stakeholders interested and eligible in participating in trading opportunities. This WQT program will allow participation by both point sources and nonpoint sources to help achieve water quality goals.
October 20, 2019 – Water Quality Trading final rule (WQ099) in Louisiana Register, Vol. 45, No. 10. The Louisiana state WQT regulations are located in the Louisiana Administrative Code (LAC) 33:IX. Chapter 26.
July 20, 2019 - LDEQ posted a Potpourri Notice to announce changes to address comments received during the public comment period of the Water Quality Trading (WQ099S) Proposed Rule.
January 20, 2019 - Water Quality Trading (WQ099) Proposed Rule in Louisiana Register, Vol. 45, No. 01, January 20, 2019. Please see the NOI for details.
The Louisiana Water Quality Trading Guidance provided here incorporates the feedback and discussions from stakeholder interactions as well as information from the EPA 2019 policy update memo. LDEQ envisions updating the Guidance as appropriate to clarify, improve, and enhance the implementation of the WQT.

Basics of WQT
According to the EPA Trading Policy (2003) and the EPA Water Quality Trading Assessment Handbook (2004), a buyer (e.g. a pollution source such as an industrial facility) purchases water quality improvements, or credits, from a seller (e.g. a farmer installing a buffer along a stream to capture sediment runoff or a facility installing technology that achieves reductions greater than established WQBEL requirements) that reduces pollutants. Both buyers and sellers will need to meet a minimum level, or baseline, before generating credits. The baseline for generating pollution reduction credits must be consistent with applicable water quality standards. In general, a credit is a reduction in pollutant loads beyond baseline conditions. More specifically, it is a measured or estimated unit of pollutant reduction per unit of time adjusted to account for applicable trading ratios. A seller generates excess load reductions by controlling its discharge beyond what is needed to meet its baseline through controlling its flow and/or its discharge concentrations. A buyer can then use the credits to meet a regulatory obligation.
