Surface Water Quality

Clean Water Act 303(d)/305(b) Integrated Report

The CWA §303(d)/305(b) Integrated Report (IR) is designed to satisfy the statutory requirements of Section (§) 303(d) and the reporting requirements of §§ 305(b) and 314 of the federal Water Pollution Control Act (33 U.S.C. 1251) commonly known as the Clean Water Act (CWA).  It is also designed to serve as a source of basic information on water quality and water pollution control programs in New Mexico.  Accordingly, the intended audience includes but is not limited to the general public, stakeholders, interest groups, consultants, state legislators, governmental agencies at all levels, as well as universities and other educational entities.  The Comprehensive Assessment and Listing Methodology (CALM) explains how New Mexico assesses surface water quality data against our most current water quality standards (20.6.4 NMAC) to determine attainment.

Contact Meredith Zeigler, Assessment Coordinator, with any questions or for additional details.

The NMED SWQB invited the public to comment on the draft 2020-2022 State of New Mexico Clean Water Act (CWA) §303(d)/§305(b) Integrated List of Assessed Surface Waters (Integrated List) during a 45-day public comment period July 27, 2020, through September 10, 2020. The Integrated List identifies whether or not a particular surface water of the state (referred to as an “assessment unit”) is currently meeting its designated uses. “Category 5” waters on the Integrated List specifically constitute New Mexico’s CWA §303(d) List of Impaired Waters.

Following the close of the public comment period, the SWQB prepared the Final Draft 2020-2022 Integrated Report, which includes the Integrated List, as amended, as Appendix A.  Appendix C contains SWQB’s Response to Comments.  The Integrated Report was approved by the New Mexico Water Quality Control Commission (WQCC)  on December 8, 2020 and approved by the U.S. Environmental Protection Agency (EPA) Region 6 on January 22, 2021.
