Gila Res. Info. Project v. N.M. Water Quality Control Comm'n

Summary

The New Mexico Supreme Court affirmed the Water Quality Control Commission’s adoption of the Copper Mine Rule, holding that the rule’s construction of the statutory phrase “place of withdrawal” is permissible, that it does not violate the Water Quality Act’s variance provision, that the point‑of‑compliance framework is authorized, and that a departure from prior agency practice does not invalidate the rule.
