Facts

The Regents of the University of California, on behalf of Los Alamos National Laboratory (LANL), challenged the New Mexico Water Quality Control Commission's adoption of a 2002 amendment to water quality standards. The amendment applied human health standards for persistent toxic pollutants to all tributaries of waters with a designated, existing, or attainable fishery use. The Regents argued that the amendment was arbitrary, capricious, unsupported by substantial evidence, and contrary to law (paras 1, 5-7).

Procedural History

• New Mexico Water Quality Control Commission, May 2002: The Commission unanimously adopted the amended water quality standards, including the contested provision (para 7).

Parties' Submissions

• Appellant (Regents of the University of California): Argued that the Commission's adoption of the amendment was arbitrary, capricious, and contrary to law. They contended that the amendment improperly applied human health standards to ephemeral tributaries without fish, failed to comply with statutory requirements, and lacked substantial evidence. They also argued that the amendment effectively designated unattainable fishery uses for tributaries and was a regulation rather than a standard, requiring additional procedural steps (paras 1, 10-18, 25-28).
• Appellee (New Mexico Water Quality Control Commission): Defended the amendment, asserting that it complied with state and federal law, was supported by substantial evidence, and was necessary to protect downstream fishery waters from persistent toxic pollutants. The Commission argued that the amendment was a standard, not a regulation, and that it provided adequate notice and followed proper procedures (paras 10-18, 25-28).

Legal Issues

• Did the Commission act contrary to law in adopting the amendment?
• Was the Commission's decision supported by substantial evidence?
• Was the Commission's action arbitrary or capricious?

Disposition

• The Court of Appeals of New Mexico affirmed the Commission's adoption of the amendment (para 37).

Reasons

Per Castillo J. (Alarid and Vigil JJ. concurring):

• Compliance with Law: The Court found that the Commission acted in accordance with state and federal law. The Commission's statement of reasons, while general, was sufficient for appellate review. The amendment did not improperly designate a fishery use for tributaries but instead applied additional protective criteria to existing uses. The Court also rejected the argument that the amendment was a regulation requiring additional procedural steps (paras 10-28).
• Substantial Evidence: The Court determined that substantial evidence supported the Commission's decision. The record included extensive testimony and data showing that persistent toxic pollutants in ephemeral tributaries could flow downstream and harm human health through bioaccumulation in fish. The Commission's decision to adopt the amendment was based on this evidence and a policy choice to proactively protect downstream waters (paras 29-34).
• Arbitrary or Capricious Action: The Court concluded that the Commission's action was neither arbitrary nor capricious. The decision was reasoned and rational, based on evidence of the risks posed by persistent toxic pollutants and the inadequacy of existing regulatory strategies to address those risks (paras 35-36).
