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. 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.
