MEMORANDUM OF DECISION AND ORDER

STEPHEN M. McNAMEE, Senior District Judge.

Before the Court are several related motions:

(1) Counter-defendant Travelers Casualty and Surety Company's Motion for Summary Judgment Re: Equitable Contribution (Doc. 80);

(2) Defendant/Counter-claimant Employers Insurance Company of Wausau's Motion for Partial Summary Judgment (Doc. 83);

(3) Counter-defendant Hartford Accident and Indemnity Company's Motion for Summary Judgment Re: Equitable Contribution (Doc. 85);

(4) Plaintiff/Counter-defendant Nucor Corporation's Cross Motion for Partial Summary Judgment (Doc. 124); and

(5) Defendant/Counter-claimant Employers Insurance Company of Wausau's Motion to Strike (Doc. 125).

The motions are fully briefed. (Docs. 115, 118, 120, 127, 129, 132, 135, 136.) After considering the parties' briefing, and having determined that oral argument is unnecessary,1 the Court issues the following ruling.

BACKGROUND

This insurance coverage dispute arose from a federal environmental liability lawsuit filed against Plaintiff/Counter-defendant Nucor Corporation ("Nucor"). In 2010, the Roosevelt Irrigation District ("RID") filed suit against Nucor alleging that Nucor and dozens of other potentially responsible parties ("PRPs") are responsible for releasing pollutants into Phoenix groundwater from the 1960s to the 1980s, resulting in contamination to wells owned and operated by RID. The underlying suit (hereafter referred to as the "RID action" or "RID suit") seeks recovery of the costs associated with remediation of the groundwater contamination and damage to RID's real property.

A. Previous related litigation against Nucor.

For slightly over four years in the 1960s, Nucor owned and operated a manufacturing facility located on West Osborn Road in Phoenix, Arizona (hereafter "the Site" or "the WOR facility"), where it manufactured electronic components. (Doc. 1-1 at 2-3.) As part of its manufacturing process, Nucor used a solvent called trichloroethylene ("TCE") to clean and degrease parts, tools, and machines. (Id. at 3.) During the 1980s, TCE was discovered in the groundwater in the west-central area of Phoenix. (Id.) As a result, Nucor has been sued in four separate lawsuits, including most recently the RID action. (Id.) The four lawsuits are:

(Id.) Nucor retained the law firm of Fennemore Craig to defend it in connection with all four lawsuits. (Id. ¶ 16.)

Defendant Employers Insurance Company of Wausau (hereafter "Wausau") issued four primary liability insurance policies to Nucor for the period from January 1, 1968 to January 1, 1972. (Doc. 84 ¶ 1.) Each of the Wausau policies at issue in this case included the following provision:

(Id.)

Defendant Travelers Casualty & Surety Company (hereafter "Travelers") issued five primary liability insurance policies to Nucor for the period from January 1, 1961 to January 1, 1966, and ten primary liability insurance policies for the period from January 1, 1975 to January 1, 1985. (Id. ¶ 2.) Defendant Hartford Accident and Indemnity Company (hereafter "Hartford") issued three primary liability insurance policies to Nucor for the period from January 1, 1972 to January 1, 1975. (Id. ¶ 3.)

In 1997, Nucor filed a coverage action in Maricopa County Superior Court against insurers who provided liability insurance to Nucor in the 1960s to 1980s (hereafter referred to as "Nucor I"). (Doc. 84 ¶ 25.) In Nucor I, which was litigated over the course of 13 years, Nucor argued that the environmental claims arising out of the alleged contamination at the WOR facility involved a continuous trigger of coverage and thus involved their insurers from 1961 to 1984. (Id.) The state court issued final judgments in Nucor I in 2010; the judgments were subsequently appealed to the Arizona Court of Appeals, which issued a published opinion and an unpublished memorandum decision on November 23, 2010. (Id.) Nucor filed a petition for review with the Arizona Supreme Court as to two rulings of the appellate court, but neither of the issues Nucor appealed are relevant to the issues presented by the motions currently before this Court. (Id.)

One of the central issues of dispute in Nucor I was the extent of Nucor's primary insurers' obligation to contribute to the payment of Nucor's defense costs in the various environmental actions that had been brought against Nucor. (Id. ¶ 26.) In 2005, During the pendency of Nucor I, but prior to the entry of judgment, Nucor entered into settlement agreements with both Travelers and Hartford. (Id.) The settlement between Nucor and Travelers provided that Travelers' payment to Nucor would "exhaust all coverage potentially available to Nucor under the Policies for Environmental Contamination Claims Arising out of the [WOR] Site." (Doc. 81 ¶ 11.)

The settlement between Nucor and Hartford provided that in exchange for the payment by Hartford, Nucor "fully and forever releases and discharges Hartford from Claims ... that Nucor has or may have against Hartford with respect to ... the Nucor Policies.... Furthermore, by virtue of the foregoing releases, Hartford shall have no duty to defend or indemnify Nucor with respect to any Claim." (Doc. 87 ¶ 9.) The Hartford settlement also stated that "[t]he Parties agree that the Settlement Sum will exhaust any and all potentially applicable limits of all Hartford Accident and Indemnity Company primary policies issued to Nucor." (Id. ¶ 10.)

B. The RID Action

On September 11, 2009, Nucor notified Wausau that it had received a demand letter and a draft complaint from RID alleging that Nucor was a PRP for groundwater pollution that impacted wells owned and operated by RID. (Id. ¶ 5.) On November 2, 2009, Wausau sent a reservation of rights letter to Nucor, reserving its rights to assert possible coverage defenses as to whether the RID suit constituted a claim for "damages" for "property damages" and whether there was an "occurrence" as defined by the policies. (Id. ¶ 7.) In the letter, Wausau also wrote that if Nucor were served with a lawsuit, it should notify Wausau "so that if appropriate [Wausau] may appoint counsel to defend Nucor's interests." (Id.)

RID filed its complaint in the underlying action against Nucor and other defendants in February 2010, and thereafter filed and served a First Amended Complaint in July 2010. (Id. ¶¶ 8-9.) RID's complaint describes the nature of the action as follows:

(Id. ¶ 9.) On November 11, 2011, Wausau withdrew its right to deny coverage to the extent Nucor's liability arose from intentional acts or it expected or intended any property damage. (Id. ¶ 10.)

As stated above, Nucor retained Fennemore Craig to handle its defense in the RID action. (Id. ¶ 13.) Fennemore Craig was simultaneously retained by three other defendants to represent them in the RID action — Kinder Morgan G.P., Inc., BP West Coast Products, LLC, and BNSF Railway Company. (Id. ¶ 14.) Wausau expressed to Nucor its concerns with Fennemore Craig's representation of multiple defendants in the RID action. (Id. ¶ 15.)

For the period from the hiring of Fennemore Craig for the RID action through June 2011, Nucor sought from Wausau reimbursement of defense costs totaling $601,462, which included "Nucor only" attorneys' fees of $461,326, and additional fees of $140,136 representing Nucor' `s 25% share of additional amounts billed by Fennemore Craig for work the firm performed jointly on behalf of Nucor and the three other RID action defendants. (Id. ¶ 17.) Wausau has to-date paid for a portion of the defense bills submitted by Nucor, but has not paid amounts it deems excessive or unreasonable, nor paid amounts for Nucor's share of fees billed by Fennemore Craig for work performed jointly on behalf of Nucor and the three other RID defendants. (Id. ¶ 18.)

On November 11, 2011, Wausau informed Nucor that it wished to exercise its right under the policies to appoint defense counsel for Nucor in the RID action, and informed Nucor that it had retained attorney Kevin Neal of the firm Jones, Skelton & Hochuli, P.L.C. to handle Nucor's defense. (Id. ¶ 19.) Wausau informed Nucor that it would pay the necessary and reasonable fees of the Fennemore Craig firm through November 30, 2011, and also informed Nucor that Wausau would not object if it wished to continue to retain Fennemore Craig as associate defense counsel in the RID action at Nucor's own expense. (Id. 19.) Nucor objected to Wausau's attempt to appoint defense counsel. (Id. ¶ 20.)

Wausau also requested that Nucor tender the defense of the RID suit to its other insurers, including Hartford and Travelers. (Id. ¶ 21.) On March 17, 2010, Nucor notified Wausau that it had not tendered the RID suit to any other insurers and that it refused to do so in light of settlement agreements Nucor had entered into with Hartford and Travelers. (Id.) Subsequently, Wausau notified Hartford and Travelers about the RID action and requested that they pay a share of Nucor's defense costs. (Id.) Hartford and Travelers have refused to pay any of Nucor's defense costs in the RID action, on the grounds that they have no obligation to contribute to Nucor's defense costs based upon the settlement agreements they reached with Nucor in connection with previous environmental claims. (Id. ¶ 22.)

Nucor brought this case against Wausau asserting claims for declaratory relief, breach of contract, and breach of the covenant of good faith and fair dealing. (Doc. 1-1 at 20-26.) For its claim of declaratory relief, Nucor seeks declaration that, inter alia: Wausau has a duty to defend Nucor in the RID suit; Wausau is obligated to provide Nucor with a complete defense to every claim in the RID suit; Nucor has the right to designate counsel of its choosing to defend the RID suit; and Wausau must reimburse Nucor for all reasonable and necessary defense costs. (Id. at 22-23.)

Wausau answered Nucor's complaint, and asserted four counterclaims: (1) for declaratory relief against Nucor regarding Wausau's right to appoint defense counsel in the RID suit; (2) for declaratory judgment that Nucor breached the cooperation provision of the insurance policies issued by Wausau; (3) for equitable contribution against Hartford and Travelers; and (4) for declaratory relief against Nucor, Hartford, and Travelers regarding the rights and responsibilities of Hartford, Travelers, and Nucor to pay for defense costs incurred in the RID action. (Doc. 5 at 15-17.)

LEGAL STANDARD

I. Motions for Partial Summary Judgment

Upon motion at any time, a party defending against a claim may move for "partial summary judgment," that is, "summary judgment in the party's favor as to... any part thereof." Fed.R.Civ.P. 56(b). A court must grant summary judgment if the pleadings and supporting documents, viewed in the light most favorable to the nonmoving party, "show that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law." Fed.R.Civ.P. 56(c); see Celotex Corp. v. Catrett, 477 U.S. 317, 322-23, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986); Jesinger v. Nevada Fed. Credit Union, 24 F.3d 1127, 1130 (9th Cir.1994). Substantive law determines which facts are material. See Anderson v. Liberty Lobby, 477 U.S. 242, 248, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986); see also Jesinger, 24 F.3d at 1130. "Only disputes over facts that might affect the outcome of the suit under the governing law will properly preclude the entry of summary judgment." Anderson, 477 U.S. at 248, 106 S.Ct. 2505. The dispute must also be genuine, that is, the evidence must be "such that a reasonable jury could return a verdict for the nonmoving party." Id.; see Jesinger, 24 F.3d at 1130.

A principal purpose of summary judgment is "to isolate and dispose of factually unsupported claims." Celotex, 477 U.S. at 323-24, 106 S.Ct. 2548. Summary judgment is appropriate against a party who "fails to make a showing sufficient to establish the existence of an element essential to that party's case, and on which that party will bear the burden of proof at trial." Id. at 322, 106 S.Ct. 2548; see also Citadel Holding Corp. v. Roven, 26 F.3d 960, 964 (9th Cir. 1994). The moving party need not disprove matters on which the opponent has the burden of proof at trial. See Celotex, 477 U.S. at 317, 106 S.Ct. 2548. The party opposing summary judgment "may not rest upon the mere allegations or denials of [the party's] pleadings, but ... must set forth specific facts showing that there is a genuine issue for trial." FED. R. CIV. P. 56(e); see Matsushita Elec. Indus. Co. v. Zenith Radio, 475 U.S. 574, 585-88, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986); Brinson v. Linda Rose Joint Venture, 53 F.3d 1044, 1049 (9th Cir.1995).

II. Equitable Contribution

A federal court sitting in diversity applies state substantive law. See Hambleton Bros. Lumber Co. v. Balkin Enterprises, Inc., 397 F.3d 1217, 1227 (9th Cir.2005). Thus, this Court applies Arizona law to the interpretation of the insurance contracts at issue. See Benevides v. Arizona Prop. & Cas. Ins. Guar. Fund, 184 Ariz. 610, 613, 911 P.2d 616, 619 (App.1995).

Under Arizona law, an insurer has a duty to "defend the insured against any claim `potentially covered by the policy.'" Pueblo Santa Fe Townhomes Owners' Ass'n v. Transcon. Ins. Co., 218 Ariz. 13, 19, 178 P.3d 485, 491 (App.2008). The language of the insurance policy controls the scope and extent of the insurer's duty to defend. Cal. Cas. Ins. Co. v. State Farm Mut. Auto. Ins. Co., 185 Ariz. 165, 168, 913 P.2d 505, 508 (App.1996). The duty to defend arises "at the earliest stages of the litigation and generally exists regardless of whether the insured is ultimately found liable." Regal Homes, Inc. v. CNA Ins., 217 Ariz. 159, 164, 171 P.3d 610, 615 (App.2007). The duty to defend focuses on the facts alleged rather than the legal characterization of the causes of actions alleged in the complaint against the insured. Kepner v. Western Fire Ins. Co., 109 Ariz. 329, 331, 509 P.2d 222, 224 (1973).

Generally, an insurer must contribute to the defense costs borne by another insurer in defending their mutual insured. Nat'l Indem. Co. v. St. Paul Ins. Co., 150 Ariz. 458, 459, 724 P.2d 544, 545 (1986). To determine whether an insurer will be required to contribute to another insurer's payment of costs on behalf of an insured, Arizona courts apply a four-part test: "the policies must cover (1) the same parties, (2) in the same interest, (3) in the same property, [and] (4) against the same casualty." Granite State Ins. Co. v. Emp'rs Mut. Ins. Co., 125 Ariz. 275, 278, 609 P.2d 90, 93 (App.1980).

DISCUSSION

I. Wausau's Motion to Strike Nucor's Cross-Motion

On May 25, 2013, Nucor filed its "Opposition to Employers Insurance Company of Wausau's Motion for Partial Summary Judgment Concerning Right to Select Independent Counsel and Cross-motion for Partial Summary Judgment." (Doc. 124.) On April 8, 2013, Wausau filed its Reply in support of its motion for partial summary judgment, and its motion to strike Nucor's cross-motion. (Doc. 125.) Wausau moves to strike Nucor's cross-motion on grounds that it violates the Court's case management order that all motions for summary judgment on defense-related issues and Wausau's right to equitable contribution be filed no later than February 25, 2013. (Id. at 6.)

Although Rule 16(f), FED.R.CIV.P., authorizes sanction against a party for failure to obey a scheduling order, the Court will deny Wausau's motion to strike. Nucor's cross-motion, filed simultaneously with its Response to Wausau's motion for partial summary judgment, concerns the same issue as that raised in Wausau's motion — whether Wausau has the right to appoint Nucor's defense counsel in the RID action. Wausau has responded to Nucor's cross-motion, the parties rely on the same factual evidence in support of their respective motions, and Wausau has alleged no injury to any substantial right. (See Rule 61, FED.R.CIV.P.) Thus, there is no prejudice to Wausau in allowing the issue to be fully briefed before the Court, and Nucor's technical delay in filing the cross-motion was harmless. Thus, the motion to strike will be denied.

II. Wausau and Nucor's Cross-motions for Partial Summary Judgment Re: Wausau's Right to Select Defense Counsel

Wausau moves for partial summary judgment in its favor on the issue of whether Wausau has the right to appoint its own counsel to defend Nucor in the RID action. (Doc. 83 at 7.) Nucor moves for partial summary judgment in its favor on the same issue. (Doc. 124.)

Wausau argues that summary judgment in its favor on this issue is appropriate on the grounds that Arizona law confers upon an insurer the right to appoint defense counsel for the insured, even where the insurer is defending under a reservation of rights. (Doc. 83 at 12-15.) Nucor argues that summary judgment should be entered in its favor, on three independent grounds: (1) that Arizona law provides no such absolute right to an insurer; (2) that even if such a right existed, Wausau has waived that right by its use and reliance upon Fennemore Craig in the RID action for an extended period of time and by its lengthy delay in seeking to compel Nucor's use of different counsel; and (3) that Wausau is estopped from belatedly attempting to exercise a right to appoint counsel because of the prejudice to Nucor that would result. (Doc. 124 at 7-17.)

Typically, when a defense is provided by a liability insurer, "as part of the insurer's obligation to provide for the insured's defense, the policy grants the insurer the right to control that defense — which includes the power to select the lawyer that will defend the claim." Paradigm Ins. Co. v. The Langerman Law Offices, P.A., 200 Ariz. 146, 149, 24 P.3d 593, 596 (2001) (citations omitted). However, where an insurer accepts the duty to defend under a reservation of rights, it "relinquishes to the insured control of the litigation." United Services Auto. Ass'n v. Morris, 154 Ariz. 113, 119, 741 P.2d 246, 252 (1987). "An insured that is notified of its insurer's reservation of rights is on notice of the conflict of interest and is free, upon proper notice to the insurer, to act to protect its rights in the litigation with the claimant." Pueblo Santa Fe Townhomes Owners' Ass'n v. Transcontinental Ins. Co., 218 Ariz. 13, 19, 178 P.3d 485, 491 (App.2008).

The Court agrees with Wausau that there is no support in Arizona case for the blanket proposition that an insurer defending under a reservation of rights loses its right to appoint defense counsel for its insured. Although the courts in Morris and Pueblo Santa Fe indicated that an insurer defending under a reservation of rights loses some of its contractual rights to control the defense of an insured, neither of those opinions, nor any other Arizona case that the Court has found, addressed the specific issue of whether an insurer loses its right to appoint defense counsel.

Thus, in the absence of any authority in support of Nucor's claim that it has a right to appoint its own defense counsel, the Court finds that Wausau has a contractual right under the insurance policies to appoint defense counsel in the underlying RID action.

Nucor argues, however, that even if Wausau does have this right, it has waived the right by failing to attempt to select independent counsel in a timely manner. (Doc. 124 at 13.) In support of this argument Nucor notes the following undisputed facts. Nucor first tendered the RID claim to Wausau in September 2009, after receiving a demand letter and draft complaint. (Doc. 84 ¶ 5.) On July 16, 2010, Fennemore Craig provided Wausau with an update on recent developments in the RID litigation. (Doc. 124-1 at 23.) Wausau responded to this communication from Fennemore Craig by requesting "an outline as to defense strategy," and stating that it should "include identification of the defense team and corresponding responsibilities, as well as a budget. We'd like to get a handle on the direction and projected costs of this litigation." (Id.)

The RID complaint was filed against Nucor on July 29, 2010; On August 13, 2010, Fennemore Craig provided to Wausau some of the information requested in the July 16 communication, gave further update on the RID suit, and tendered the official RID complaint. (Id.) On October 19, 2010, Wausau thanked Fennemore Craig for the August 13 letter, noted that Fennemore Craig had "significant background and knowledge of the [WOR] site, particularly with regards to the Nucor plume," and requested additional information from Fennemore. (Id. at 24.) Fennemore Craig provided to Wausau the requested additional information on December 6, 2010. (Id.) It was not until November 11, 2011, that Wausau informed Nucor that it had decided to exercise its right under the policies to appoint defense counsel for Nucor in the RID action. (Doc. 84 ¶ 19.)

Waiver is the voluntary relinquishment of a known right or conduct warranting an inference that such a right has been relinquished. Services Holding Co., Inc. v. Transamerica Occidental Life Ins. Co., 180 Ariz. 198, 207, 883 P.2d 435, 444 (App. 1994). "Waiver of right requires a clear showing of an intent to waive that right. Intent to waive, however, may be inferred from conduct." Id. at 206, 883 P.2d at 444 (internal citations omitted). Waiver is a question of fact to be determined by the trier of fact. Chaney Bldg. Co., Inc. v. Sunnyside School Dist. No. 12, 147 Ariz. 270, 273, 709 P.2d 904, 907 (App.1985).

Wausau argues that the facts do not establish that it waived its right to appoint defense counsel for Nucor in the RID action. (Doc. 125 at 11.) However, Wausau neglects to address the settled legal reality that whether Nucor could infer waiver from Wausau's conduct is a question of fact for the trier of fact. The Court finds that Nucor has raised sufficient evidence to establish a genuine dispute of material fact by which waiver could be found. It is undisputed that Wausau had multiple communications with Fennemore Craig concerning Nucor's defense in the RID action, spanning a time period of over a year. It is further undisputed that Nucor did not attempt to assert its right to appoint counsel at any time prior to November 11, 2011, nearly two years after Wausau first received notice of the RID demand letter and draft complaint against Nucor. These facts, viewed in the light most favorable to the nonmoving party, are sufficient to raise a genuine dispute, and thus summary judgment against Nucor's claim of waiver is inappropriate.

The Court also finds, however, that summary judgment in Nucor's favor is similarly inappropriate, because Wausau disputes Nucor's inferences from the facts, and raises facts by which a reasonable trier of fact could find that it did not waive its right to appoint counsel. As Wausau notes, after it received notice of the potential RID suit in September 2009, it sent a reservation of rights letter to Nucor on November 2, 2009 confirming that if Nucor were served with a lawsuit, it should notify Wausau "so that if appropriate, we may appoint counsel to defend Nucor's interest." (Doc. 84 ¶ 7.) Further, Wausau notes that the RID action was not officially filed or tendered to Wausau until July, 2010, and that up to the present very little litigation has been conducted in the RID action. (Doc. 84 ¶ 9; Doc. 125 at 9.) Thus, Wausau argues, Nucor could not reasonably have inferred that the delay between tender of the RID suit and Wausau's attempt to appoint counsel amounts to a showing of intentional waiver.

The Court agrees that a reasonable jury could find that waiver cannot be inferred from Wausau's conduct. Accordingly, this remains a factual question for the trier of fact, and may not be disposed of on summary judgment.

Nucor argues next, however, that summary judgment is appropriate because Wausau is estopped from exercising its right to appoint counsel. (Doc. 124 at 15.) According to Nucor, Wausau is estopped because it previously consented to Nucor's retention of Fennemore Craig in previous suits brought against Nucor for pollution at the WOR site, and by the same conduct Nucor points to above in support of its argument that Wausau has waived its right to appoint counsel. (Id.)

Estoppel occurs when one party, by its conduct, induces another to believe and have confidence in certain material facts, which inducement results in justifiable reliance thereon, resulting in injury to the person thus relying. Pueblo Santa Fe, 218 Ariz. at 21, 178 P.3d at 493. Nucor asserts that it relied on Wausau's conduct in approving the retention of Fennemore Craig, and will be prejudiced if Nucor is now allowed to substitute new, inexperienced counsel in place of Fennemore Craig, which has been defending Nucor in suits concerning its operation of the WOR facility for more than 20 years. Wausau argues that it is not estopped from appointing counsel because the undisputed facts do not support a showing of prejudice — according to Wausau, Nucor cannot demonstrate that it will suffer any prejudice if Jones Skelton is appointed to handle the RID action because there is no reason to assume that Jones Skelton will be unable to assimilate and use the information and work product Nucor and Fennemore Craig have developed to assist in the defense of the RID action. (Doc. 125 at 13.)

The Court finds that the undisputed facts, viewed in the light most favorable to the non-moving party (which in the case of cross-motions for summary judgment, as here, is both parties), could reasonably support a finding in either party's favor. The question of whether Nucor will be prejudiced by Wausau's attempt to substitute counsel at this stage in the RID action is a question for the jury, and the undisputed facts can reasonably be interpreted either way. Thus, a genuine issue of material fact exists for the trier of fact.

For these reasons, the Court will deny both the cross-motions for partial summary judgment on the issue of whether Wausau maintains the right to appoint Nucor's defense counsel in the RID action. Although the Court agrees with Wausau that it has a contractual right to appoint defense counsel for Nucor, the Court finds that Nucor has raised sufficient facts by which a reasonable trier of fact could conclude that Nucor has waived that right or is estopped from asserting that right.

III. Wausau and Counter-Defendants' Cross-motions for Summary Judgment Re: Equitable Contribution

Wausau moves for partial summary judgment in favor of its counterclaim for equitable contribution from Travelers and Hartford for Wausau's defense of Nucor in the RID action. (Doc. 83 at 16.) Travelers and Hartford simultaneously move for summary judgment against Wausau's counterclaim. (Docs. 80, 85.)

Travelers and Hartford both argue that summary judgment in their favor is appropriate because Wausau's claim for equitable contribution from them fails as a matter of law. According to Travelers and Hartford, the settlement agreements they each entered into with Nucor in Nucor I fully exhausted any liability they may have had under the insurance policies for any future claims against Nucor arising from environmental contamination at the WOR facility. Thus, they argue that they have no obligation, real or potential, to defend Nucor in the RID suit, and thus that Wausau has no claim for equitable contribution.

Wausau argues next that the settlement agreements do not operate to preclude equitable contribution from Hartford and Travelers for Nucor's defense in the RID action because even where an insurer tenders its full policy limits to the insured, its obligation to contribute to the defense of the insured is not extinguished. (Doc. 83 at 18.) In support of this claim, Wausau cites to California Cas. Ins. Co. v. St. Farm Mut. Auto. Ins. Co., 185 Ariz. 165, 913 P.2d 505 (App.1996.)

Wausau's reliance on this case is misplaced, however; there, the Arizona Court of Appeals was considering whether the insurer was immune from a claim for equitable contribution after the insurer had made a full payment under its insured's liability policy. Id. The insurer in that case did not, however, obtain a settlement agreement with its insured discharging its duty to defend. Id. Indeed, in finding that the insurer was still exposed to potential claims for equitable contribution from other insurers of their mutual insured, the court noted that "most decisions from other jurisdictions that have construed language similar to that on which [the insurer] relies have held that a liability insurer's payment of its full policy limits discharges its duty to defend a claim against the insured only if made pursuant to a settlement or in full or partial satisfaction of a judgment entered on the claim against the insured." Id. at 168, 913 P.2d at 508 (emphasis in original); see also Anderson v. United States Fidelity & Guar. Co., 177 Ga.App. 520, 339 S.E.2d 660, 661 (1986) (term "exhaust" does not mean paying policy limits into court without insured's consent, but rather paying settlement or judgment that entirely depletes policy limits); Samply v. Integrity Ins. Co., 476 So.2d 79, 83-84 (Ala. 1985) (insurer could not avoid duty to defend by tendering payment of policy limits without settlement or insured's consent).

The Court agrees with Travelers and Hartford that the settlement agreements they entered into with Nucor in 2005 extinguished their duty to defend or indemnify Nucor for any and all claims relating to groundwater contamination at the WOR facility. This is not a case where Travelers and Hartford seek to avoid their duty to contribute to Nucor's defense by unilaterally paying policy limits to the insured and then disavowing the duty to defend. Rather, this is a case where after years of litigation over Travelers' and Hartford's coverage obligations to Nucor, those parties entered into a settlement agreement whereby those insurers made settlement payments to Nucor in exchange for Nucor's agreement to discharge those insurers from any and all further liability or defense obligation toward Nucor in relation to environmental contamination claims in connection with Nucor's operation of the WOR facility.

The plain language of the specific settlement between Nucor and Travelers provided that the agreement would "exhaust all coverage potentially available to Nucor under the Policies for Environmental Contamination Claims Arising out of the [WOR] Site." (Doc. 81 ¶ 11.) The agreement between Nucor and Hartford, as well, provided that Nucor "fully and forever releases and discharges Hartford from Claims ... that Nucor has or may have against Hartford with respect to ... the Nucor Policies.... Furthermore, by virtue of the foregoing releases, Hartford shall have no duty to defend or indemnify Nucor with respect to any Claim." (Doc. 87 ¶ 9.) The Hartford settlement also stated that "[t]he Parties agree that the Settlement Sum will exhaust any and all potentially applicable limits of all Hartford Accident and Indemnity Company primary policies issued to Nucor." (Id. ¶ 10.)

As such, these two insurers have no liability to Nucor under the policies in connection with the RID action, which did not arise until 2009, and was not filed until 2010. Accordingly, Nucor has no right to a defense from Travelers or Hartford in the RID action, and Wausau, in turn, has no right to equitable contribution from Hartford or Travelers for Wausau's costs defending Nucor in the RID action.

The Court thus finds that this issue is appropriate for summary judgment: the Court will deny Wausau's motion for partial summary judgment of its counterclaims against Travelers' and Hartford for equitable contribution, and the Court will grant Travelers' and Hartford's cross-motions for summary judgment against Wausau's counterclaims.
