CRESCENT MINE, LLC, Case No. 2:21-cv-00310-DCN Plaintiff, MEMORANDUM DECISION AND v. ORDER

BUNKER HILL MINING CORPORATION; and PLACER MINING CORPORATION d/b/a NEW BUNKER HILL MINING CO.,

Defendants.

I. INTRODUCTION Pending before the Court is Defendant Bunker Hill Mining Corporation’s (“Bunker Hill”) Motion to Dismiss (Dkt. 19), which was later joined by Defendant Placer Mining Corporation (“Placer”) (Dkt. 21). Pending as well is Plaintiff Crescent Mine, LLC’s (“Crescent”) Motion to Dismiss Defendant Placer Mining Corporation’s Counterclaim (“Motion to Dismiss Counterclaim). Dkt. 29. On January 26, 2022, the Court held oral argument and took the motions under advisement. Upon review, and for the reasons set forth below, the Court GRANTS in part and DENIES in part Bunker Hill’s Motion to Dismiss and DENIES Crescent’s Motion to Dismiss Counterclaim as MOOT. The Court also MOOTS the pending Motion for Leave to File Second Amended Complaint. Dkt. 47. II. BACKGROUND The Bunker Hill Mine, located in northern Idaho, covers roughly 6,500 acres, with underground workings of approximately 6,000 vertical feet and 150 miles of tunnels.1 Placer acquired the Bunker Hill Mine property and its mineral rights sometime between December 1991 to April 1992, and is the current owner of the Bunker Hill Mine.

The Crescent Mine is located east of the Bunker Hill Mine. It is much smaller than the Bunker Hill Mine. When measured by tonnage produced, the Crescent Mine is approximately 2.4 percent the size of the Bunker Hill Mine. Although separate mines, the Crescent Mine and the Bunker Hill Mine were formerly owned by the same company, which constructed a tunnel (the “Y-U crosscut” or the “Yreka crosscut”) connecting the

two mines. Mines naturally fill up with water, often through groundwater recharge, and the Crescent Mine and the Bunker Hill Mine are no exception. Prior to 1991, water was pumped from the lower levels of both mines to clear the area for mining. Notably, water in a mine often becomes highly contaminated and extremely acidic when it contacts exposed

minerals. This tainted water is referred to as acid mine drainage (“AMD”). The AMD created within the Bunker Hill Mine contains several heavy metals including zinc, cadmium, lead, iron, manganese, and arsenic, at levels exceeding regulatory standards. Prior to 1991, AMD was pumped from the lower levels of the Bunker Hill Mine and channeled to the Central Treatment Plant, where it was treated and discharged to a creek

flowing into the South Fork of the Coeur d’Alene River (“South Fork”). The pumping and

1 Because this is a Motion to Dismiss, all facts are from the Amended Complaint (Dkt. 24). Obviously, the facts may evolve as the adjudicative process continues and should not be considered final. Although Defendants spent considerable time claiming these facts are wrong (Dkt. 19-1, at 2), such factual disputes are inappropriate at this stage of the proceedings. treatment were necessary to prevent Bunker Hill Mine’s AMD from entering the South Fork in its untreated state, which would cause significant environmental destruction. After assuming ownership of the Bunker Hill Mine in 1991, Placer began

deliberately diverting AMD flow into the lower levels of the Bunker Hill Mine instead of conveying it to the Central Treatment Plant. This caused significant flooding of the Bunker Hill Mine’s lower workings and substantially raised the water level inside the mine. The diversion of AMD to the lower levels of the Bunker Hill Mine by Placer was sufficient to eventually cause AMD to enter the Crescent Mine via the Y-U crosscut tunnel, flooding

the Crescent Mine’s lower levels with AMD. Interestingly, Placer moved materials into the Bunker Hill Mine to construct a plug for the Y-U crosscut to prevent AMD from flowing through it to the Crescent Mine, but then failed to install the plug. By this time, the Crescent Mine was owned by a different company than the parent company that once owned both the Bunker Hill Mine and the Crescent Mine. Placer was not authorized to divert AMD

into the Crescent Mine. In 1994, the EPA determined that Placer’s intentional flooding of the Bunker Hill Mine posed an imminent and substantial risk to the environment because of the potential for the untreated AMD to be released into the South Fork. The EPA issued a unilateral administrative order directing Placer to maintain the Bunker Hill Mine water level at least

300 vertical feet below the level of the South Fork, to construct a piping system to convey AMD to the Central Treatment Plant, and then to convey all AMD from the mine to the Central Treatment Plant. Placer failed to comply with the order because it did not convey the AMD to the Central Treatment Plant and instead allowed numerous uncontrolled AMD releases from the mine. The EPA then directly stepped in and assumed ownership and operation of the Central Treatment Plant. The EPA sought reimbursement for its actions in running the

plant. In 2004, after being stonewalled by Placer, the United States sued Placer on behalf of the EPA to recover the EPA’s response costs and to secure penalties and punitive damages for Placer’s actions. In 2014, Crescent (the corporation) purchased the Crescent Mine and has owned and operated it since. In 2017, Bunker Hill (the corporation) entered into a lease agreement

with Placer to operate the Bunker Hill Mine and secured an option to purchase the mine. Under the lease agreement, Bunker Hill was given full operational control and possession over the entire Bunker Hill Mine, including management and control of the mine’s water. In 2018, Bunker Hill and the EPA entered into a settlement agreement whereby Bunker Hill agreed to perform a response action and to make a series of payments to satisfy

Placer’s liability. This, along with a consent decree, effectively ended the 2004 lawsuit. However, the AMD released into the Crescent Mine is still there. The flooded tunnels have precluded Crescent from being able to mine approximately 9.3 million ounces of silver ore and from expanding its mine. III. LEGAL STANDARD

Federal Rule of Civil Procedure 12(b)(6) permits a court to dismiss a claim if the plaintiff has “fail[ed] to state a claim upon which relief can be granted.” “A Rule 12(b)(6) dismissal may be based on either a ‘lack of a cognizable legal theory’ or ‘the absence of sufficient facts alleged under a cognizable legal theory.’” Johnson v. Riverside Healthcare Sys., LP, 534 F.3d 1116, 1121 (9th Cir. 2008) (citation omitted). Federal Rule of Civil Procedure 8(a)(2) requires a complaint to contain “a short and plain statement of the claim showing that the pleader is entitled to relief,” in order to “give the defendant fair notice of

what the . . . claim is and the grounds upon which it rests.” See Bell Atl. Corp. v. Twombly, 550 U.S. 544, 554 (2007). “This is not an onerous burden.” Johnson, 534 F.3d at 1121. A complaint “does not need detailed factual allegations,” but it must set forth “more than labels and conclusions, and a formulaic recitation of the elements.” Twombly, 550 U.S. at 555. The complaint must also contain sufficient factual matter to “state a claim to relief

that is plausible on its face.” Id. at 570. The Supreme Court’s focus on plausibility in Twombly significantly heightened the prior federal standard of fair notice. Alexander A.
