Facts
The case concerns the validity of a 2005 amendment to the definition of "surface waters of the State" under New Mexico's Water Quality Act (WQA). The amendment removed references to interstate commerce, aiming to assert state authority over water regulation and ensure protection for all waters within New Mexico, including non-perennial and intrastate waters, which constitute over 80% of the state's waters (paras 1, 8, 10).
Procedural History
- Water Quality Control Commission, May 13, 2005: The Commission adopted the 2005 amendment to the definition of "surface waters of the State" after public hearings and deliberations (paras 9-10).
Parties' Submissions
- Appellants (New Mexico Mining Association et al.): Argued that the 2005 definition was not supported by substantial evidence, improperly expanded state jurisdiction, and was unconstitutionally vague and overbroad. They also claimed the amendment lacked scientific validation for newly covered waters and disregarded industry concerns (paras 11, 13, 17, 21, 28).
- Appellees (Water Quality Control Commission and Intervenors): Defended the amendment as consistent with the WQA and necessary to protect New Mexico's waters, particularly in light of federal uncertainty following the SWANCC decision. They argued the amendment clarified jurisdiction and ensured comprehensive water protection (paras 8, 10, 16, 20).
Legal Issues
- Was the 2005 amendment to the definition of "surface waters of the State" consistent with the requirements of the Water Quality Act?
- Was the amendment supported by substantial evidence?
- Was the amendment unconstitutionally vague or overbroad?
- Did the Water Quality Control Commission act arbitrarily or capriciously in adopting the amendment?
Disposition
- The Court of Appeals of New Mexico affirmed the decision of the Water Quality Control Commission to adopt the 2005 amendment (para 31).
Reasons
Per Alarid J. (Sutin CJ. and Bustamante J. concurring):
Compliance with the Water Quality Act: The Court held that the amendment was consistent with the WQA, as it was based on credible evidence and aimed to protect all waters within New Mexico's borders. The decision to decouple state jurisdiction from federal commerce clause considerations was a legal and policy judgment, not a scientific one, and was supported by substantial evidence (paras 13-16).
Substantial Evidence: The Court rejected the appellants' claim that the amendment lacked scientific validation for newly covered waters, noting that the appellants failed to provide specific examples of such waters or evidence of their characteristics. The speculative nature of their argument did not meet the burden of proof (paras 17-19).
Vagueness and Overbreadth: The Court found the amendment was not unconstitutionally vague, as it provided clear geographic criteria for defining surface waters. The overbreadth doctrine was deemed inapplicable, as it is generally limited to cases involving fundamental rights, which were not at issue here (paras 21-27).
Arbitrary and Capricious Action: The Court determined that the Commission carefully considered opposing evidence and comments before adopting the amendment. The decision to eliminate the interstate commerce requirement was a reasoned response to federal uncertainty and aligned with the Legislature's intent to regulate all waters within the state (paras 28-30).
