Facts
The case concerns the issuance of a solid waste facility permit to Southwest Landfill, Inc. for a landfill located approximately 11 miles southwest of Albuquerque. The Atlixco Coalition and other appellants challenged the permit, raising concerns about the landfill's liner design, groundwater monitoring, proximity to property boundaries, cover design, and financial assurance for closure costs (paras 1-2).
Procedural History
- Secretary of the New Mexico Environment Department: Issued a final order granting a solid waste facility permit to Southwest Landfill, Inc., rejecting certain recommended conditions proposed by the hearing officer (headnotes, paras 1, 13).
Parties' Submissions
- Appellants (Atlixco Coalition): Argued that the Secretary's final order was arbitrary and capricious, particularly for rejecting the hearing officer's recommendations for additional groundwater monitoring and a liner between Cells 3 and 4. They also contended that the landfill's proximity to property boundaries violated regulations and that the alternative cover design and financial assurance were inadequate (paras 1, 14, 38-39).
- Appellee (Secretary of the New Mexico Environment Department): Defended the final order, asserting that the Secretary's decisions were discretionary and supported by evidence. They argued that the landfill complied with siting criteria, the alternative cover design met regulatory standards, and financial assurance was sufficient (paras 16, 29-30, 38-40).
- Intervenor-Appellee (Southwest Landfill, Inc.): Supported the Secretary's decision, emphasizing that the landfill's design and financial assurance complied with applicable regulations. They argued that the alternative cover design was equivalent to regulatory requirements and that additional groundwater monitoring was unnecessary (paras 10, 38-40).
Legal Issues
- Was the Secretary's rejection of the hearing officer's recommendations regarding the liner between Cells 3 and 4 and additional groundwater monitoring arbitrary and capricious?
- Did the landfill's proximity to property boundaries violate regulatory siting criteria?
- Did the alternative cover design comply with regulatory requirements?
- Was the financial assurance for landfill closure adequate?
Disposition
- The court affirmed the Secretary's final order regarding the landfill's proximity to property boundaries, the alternative cover design, and financial assurance requirements (paras 26, 32, 42-43).
- The court set aside the provisions of the final order concerning the liner between Cells 3 and 4 and additional groundwater monitoring and remanded these issues for further consideration and explanation (paras 26-27, 44).
Reasons
Per Armijo J. (Apodaca and Bustamante JJ. concurring):
Liner Design and Groundwater Monitoring: The court found that the Secretary failed to provide adequate reasoning for rejecting the hearing officer's recommendations regarding the liner between Cells 3 and 4 and the additional groundwater monitoring well. The Solid Waste Act and Department regulations require the Secretary to state reasons for such decisions. The lack of findings and conclusions on these issues rendered the decision arbitrary and capricious. The court remanded these issues for reconsideration and explanation (paras 14-27).
Proximity to Property Boundaries: The court deferred to the Department's interpretation that the siting criteria did not apply retroactively to Cells 1 and 2, which were constructed and closed before the current regulations. The court also accepted evidence that excavation of these cells would cause more environmental harm than benefit (paras 29-33).
Alternative Cover Design: The court upheld the Secretary's approval of the alternative cover design, finding that the Department's regulations allowed for site-specific computer modeling to demonstrate compliance. The evidence supported the conclusion that the alternative design achieved an equivalent reduction in infiltration as required by regulations (paras 34-42).
Financial Assurance: The court found sufficient evidence to support the Secretary's conclusion that Southwest's financial assurance met regulatory requirements for the alternative cover design (paras 42-43).
The court left the remaining provisions of the final order in place to avoid unnecessary disruption (para 28).
