Clerk

Justice Ingrid Gustafson delivered the Opinion of the Court. ¶1 Defendants, Appellants, and Cross-Appellees Montana Department of Environmental Quality (DEQ) and Montanore Minerals Corp. (MMC) appeal the Order on Cross-Motions for Summary Judgment issued by the First Judicial District Court, Lewis and Clark County, on July 24, 2019, which denied DEQ’s and MMC’s cross-motions for summary judgment and vacated DEQ’s 2017 issuance of Montana Pollution Discharge Elimination System (MPDES) Permit No. MT0030279 (2017 Permit) to MMC. Plaintiffs, Appellees, and Cross-Appellants Montana Environmental Information Center (MEIC), Save Our Cabinets, and Earthworks cross-appeal the District Court’s partial denial of their motion for summary judgment. ¶2 We address the following dispositive issue on appeal:

Whether DEQ unlawfully relied upon a 1992 Order of the Board of Health and Environmental Sciences when issuing the 2017 Permit.

¶3 We affirm the District Court’s vacatur of the 2017 Permit and remand to DEQ for further proceedings.

FACTUAL AND PROCEDURAL BACKGROUND ¶4 This case arises out of the Montanore Project, a proposed copper and silver mine located in the Cabinet Mountains of northwestern Montana. Silver deposits were discovered at the site of the proposed project in the early 1980s, and the permitting process for the Montanore Project began later that decade. In 1989, the Noranda Minerals Corporation (Noranda) obtained an exploration license from the Montana Department of

State Lands for the construction of an exploration adit in upper Libby Creek.1 Libby Creek is a critical habitat for bull trout. Noranda also applied for an operating permit to authorize mining. ¶5 On December 13, 1989, Noranda filed a Petition for Change in Quality of Ambient Waters with the Montana Board of Health and Environmental Sciences (BHES), seeking authorization to lower the ambient surface and ground water quality for discharges from the proposed Montanore Project in Sanders and Lincoln Counties. Pursuant to the nondegradation policy in effect at that time, BHES was allowed to authorize lower water quality if a showing was made that degradation was justified “as a result of necessary economic or social development[.]” Section 75-5-303(1), MCA (1989). ¶6 In 1991, after constructing around 14,000 feet of the Libby Creek adit, Noranda ceased construction of the adit due to elevated nitrate concentration in the surface water and low metal prices. Though Noranda ceased construction of the adit in 1991, the permitting process continued. On November 20, 1992, BHES issued its Final Decision and Statement of Reasons (BHES Order) on Noranda’s petition to lower the ambient water quality, finding that degradation of the subject waters was justified due to the beneficial economic and social impacts that would come with the mine. The BHES Order set specific numeric limitations on certain contaminants, applicable to the surface and ground water that would be affected by the Montanore Project. The provisions of the BHES Order were

to “remain in effect during the operational life of this mine and for so long thereafter as necessary.” ¶7 In June 1992, the State of Montana Department of Health and Environmental Sciences (DHES) filed a Complaint and Application for Injunction against Noranda, alleging Noranda violated Montana’s Water Quality Act (WQA) at the Libby Creek site. DHES filed its complaint after being notified by the United States Environmental Protection Agency (EPA) that it believed Noranda had violated the Clean Water Act (CWA) at the Libby Creek site.2 On May 12, 1993, the Montana Nineteenth Judicial District Court, Lincoln County, issued its Findings of Fact, Conclusions of Law, Judgment and Consent Decree, which, in relevant part, required Noranda to pay fines and apply for an MPDES permit. ¶8 Pursuant to the CWA, Congress established a permitting system known as the National Pollution Discharge Elimination System (NPDES), which is administered by the EPA. The CWA allows for states to administer their own permits, however, and in 1974 the State of Montana and EPA signed a Memorandum of Agreement (MOA), which transferred the responsibility of issuing NPDES permits within Montana to DEQ.3 Pursuant to this arrangement, DEQ is responsible for issuing MPDES permits. Though the

The stated objective of the CWA is “to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters.” 33 U.S.C. § 1251(a). 3 At the time known as DHES.

responsibility of issuing MPDES permits has been transferred to DEQ, EPA continues to review, comment on, and/or make recommendations to DEQ regarding proposed MPDES permits. Under the MOA, if EPA does not object to a proposed permit, its non-objection “shall be considered as concurrence” in the issuing of the permit. ¶9 Noranda ultimately obtained its MPDES permit for the Montanore Project in 1997. The permit allowed discharges from the Libby adit to Libby Creek and nearby groundwater. The 1997 permit allowed three outfalls: Outfall 001 for a percolation pond discharging to groundwater; Outfall 002 for a drainfield with three infiltration zones discharging to groundwater; and Outfall 003 for a pipeline outlet to Libby Creek. In 2001, Noranda applied to renew the MPDES permit. DEQ administratively extended the MPDES permit past its February 28, 2002 expiration date while it considered Noranda’s September 17, 2001 permit renewal application. In September 2002, Noranda informed DEQ and the Kootenai National Forest (KNF) that it was relinquishing its approval to operate and construct the Montanore Project. Noranda requested termination of its MPDES permit in March 2003, but DEQ denied the request, noting “that it may be necessary to maintain the MPDES permit until reclamation work was completed.” Noranda had previously closed the adit and started reclamation work, which was not fully completed by the time it requested termination of the MPDES permit in 2003. Noranda’s other permits for the proposed mine, outside of the MPDES permit and DEQ-issued Hard Rock permit #00150, either expired or were terminated by 2002. See Mines Mgmt., Inc. v. Fus, 2019 MT 276, ¶ 8 n.6, 398 Mont. 15, 453 P.3d 371.
