Water Quality Standards
|New Mexico’s Water Quality Standards, codified at 20.6.4 NMAC, define water quality goals by designating uses for rivers, streams, lakes and other surface waters, setting criteria to protect those uses, and establishing antidegradation provisions to preserve water quality. The Standards are adopted by the Water Quality Control Commission (WQCC), then approved by the United States Environmental Protection Agency (US EPA) under the federal Clean Water Act (CWA).
Contact Jennifer Fullam, Standards Coordinator, with any questions about WQS activities.
|2020 Triennial Review|
|In accordance with Section 303(c)(1) of the CWA and 220.127.116.11 New Mexico Administrative Code (“NMAC”), states are required to hold public hearings at least once every three years to review, amend, and adopt water quality standards, as applicable. This is referred to as a “Triennial Review”. The 2020 Triennial Review has been initiated and filed with the Water Quality Control Commission under WQCC 20-51(R).|
