EPA's Water Quality Trading Policy

Summary
On January 13, 2003, the Environmental Protection Agency announced a Water
Quality Trading Policy intended as an innovative approach to assist industry and
municipalities in meeting Clean Water Act obligations. Trading allows one source to
meet regulatory requirements by buying credit for pollutant reductions from another
source that has lower pollution control costs. The policy revises a 2002 proposal which
reflected lessons learned from a similar trading policy issued by the Clinton
Administration in 1996. Water quality or effluent trading projects have occurred in the
United States since the early 1980s. The new policy is generally supported by industry
groups, state and local governments, and agriculture groups. Environmental groups are
split on the concept. Some argue that it is not lawful and are critical that the Bush
Administration policy lacks a number of details that they regard as necessary. Others
support the concept, with adequate safeguards, as a valuable tool in cleaning up
waterways. Congress has conducted some oversight of water quality trading and could
continue doing so as the new policy is implemented. Legislation to codify a water
trading policy in the Clean Water Act could be considered, as well. This report provides
background on water quality trading and the EPA policy. It will not be updated.
What is Water Quality Trading?
The Clean Water Act (CWA) provides a two-tiered approach to water quality
protection. At a minimum, all point source dischargers (i.e., industrial facilities and
municipal sewage treatment plants) must attain technology-based requirements to limit
pollutant concentrations in effluents. These requirements take the form of nationally
uniform standards which are incorporated in discharge permits issued to individual
facilities. The Act also requires that point sources meet more stringent effluent
limitations in certain circumstances. If technology-based controls are insufficient to attain
state-established ambient water quality standards for specific waterbodies, these standards
serve as the regulatory basis for developing more stringent effluent limitations to be
applied to point sources or other dischargers through additional control measures.
Since enactment of the CWA in 1972 (P.L. 92-500), the nation has made much
progress towards the Act's water quality goals through its program of technology-based
effluent limits for industrial and municipal point sources. However, as the Environmental
