Defendant Amoco Pipeline Company appeals from the district court’s confirmation of an arbitration award. We exercise jurisdiction pursuant to 29 U.S.C. § 1291 and affirm.
I. Background
I. Facts
In 1993, Ernest Bowen noticed an oily sheen in Flag Branch Creek, which is located on his property. After investigating the matter, the Oklahoma Corporate Commission (OCC) concluded remediation of the creek would be more detrimental than beneficial. In 1993, however, Mr. Bowen again observed a sheen in the creek, after which he notified the Pollution Control Division of the OCC, as well as Amoco Pipeline Company (Amoco) and Koch Gathering Systems, Inc. (Koch). Both Amoco and Koch own oil pipelines that cross the creek; Koch owns two idled lines and Amoco owns two idled lines and two active lines. After being notified by Mr. Bowen, Amoco retained Geosearch Environmental to determine the source of the sheen. Although Geosearch found hydrocarbon contamination near the creek, it concluded the source was an upstream historic release of oil, rather than a leak from Amoco’s pipelines. Contrary to Amoco’s conclusions, research conducted by Mr. Bowen’s expert, Fox Hollow Consultants, Inc., suggested that a leak in Amoco’s lines may be the source of contamination. Under Fox Hollow’s theory, oil had leaked from Amoco’s lines, migrated downward to the water table about nine feet below, and then floated on the water table to the creek.
In a memorandum dated September 1996, the OCC summarized the information available regarding the contamination in Flag Branch Creek and reached some conclusions. In evaluating potential sources of the contamination, the OCC dismissed oil wells and old documented pipeline leaks. No oil well was close enough to the creek to be the source, and the two nearby documented leaks from Koch pipelines could not have contaminated Flag Branch Creek because they were contained within them immediate spill areas. Because wells and documented leaks were not the source, the OCC concluded the source of the hydrocarbon contamination must be an undocumented leak from one of the six pipelines. Through deductive rea *928 soning, the OCC arrived at a theory similar to that proposed by Fox Hollow Consultants: oil from one of the lines leaked into the porous sandy alluvial deposits, migrated downward to the water table approximately nine to ten feet below the surface, and floated on the water table to the creek. In order to determine the source, the OCC recommended Koch and Amoco uncover their lines in order to expose any visual evidence of historic or current leaks.
Despite Amoco’s repeated assertions of its good corporate citizenship and willingness to follow all rules and regulations, it refused to follow the OCC’s recommendation and uncover its pipelines, arguing uncovering the lines would be unnecessary and jeopardize the lines’ safety. After performing some trenching around its lines and finding no hydrocarbons, Amoco continued to deny any responsibility for the contamination but emphasized that, were Amoco the responsible party, it would clean up the pollution. In April 1997, Koch concluded its investigation. The following month, the OCC sent Amoco a letter explaining that Koch’s information indicated Amoco’s pipeline on the east side of the creek may be the source of contamination. Despite this information, Amoco continued its refusal to strip the lines, offering instead to do some soil borings and recommending the Oklahoma Energy Resources Board (OERB) become involved.
Displeased with Amoco’s continued denial of any responsibility, Mr. and Mrs. Bowen filed a lawsuit in May 1998 in federal district court, asserting a cause of action for damages to real property, nuisance, trespass, unjust enrichment, breach of contract, and exemplary damages. In July, Amoco asked the district court to stay the proceeding and order the dispute to arbitration pursuant to an enforceable arbitration agreement. 1 In arguing their motion to compel arbitration, Amoco contended the arbitration panel would have the power to decide all claims, an assertion they now refute. The Bowens objected to arbitration, challenging the arbitration agreement as unenforceable. In October 1998, the district court granted Amoco’s motion and entered an order compelling arbitration.
In July 1998, Amoco responded to the Bowens’ interrogatories, continuing to deny its lines were the source of hydrocarbon contamination in the creek. In addition, Amoco explicitly denied that any leaks or spills attributable to its pipeline operation had occurred on the Bowens’ property and even denied the existence of pollution in the soil. The following month, Fred Hesser, a district environmental health and safety coordinator for Amoco, stated in his deposition that from 1995 to January 1998 he encountered no evidence indicating Amoco might be the source of the contamination. In October, however, Amoco’s tests confirmed the presence of hydrocarbons in the soil under its lines but found no contamination in the groundwater.
In June and July of 1999, three years after the OCC recommended that Amoco uncover its pipelines, Amoco exposed limited portions of its lines on the Bowens’ property and admitted the existence of contaminants next to the lines. Significantly, the stripping of the lines revealed a pipeline replacement in the contaminated area. Less than two months before the arbitration hearing, the Bowens discovered that Amoco had replaced approximately 1,000 feet of pipeline on the east side of *929 the creek. According to the Bowens’ expert, the 1,000 feet of replaced pipeline corresponds almost exactly with the contaminated creek area. Although Amoco had not explicitly disclosed the line replacement and had repeatedly denied any link to the contamination, it claimed to have provided the Bowens with a line sheet showing the replacement. Amoco did not, however, explain the information contained in the line sheet, which was technical and difficult to read, until the arbitration hearing when its employee testified that approximately 1,000 feet of pipeline was replaced in 1950.
Other than the line sheet, Amoco claimed it could find no other records detailing the reasons for and circumstances surrounding the 1950 line replacement— despite some testimony that it was corporate practice to keep such records. 2 Although Amoco’s employees and experts argued the line replacement could have been a preventative measure, they admitted a leak in the line would be one explanation for the line replacement and for the concentration of crude oil in the soil in that exact location. Moreover, after years of denying any connection to the contaminated soil, Dennis Beckman, Fred Hesser’s replacement, finally testified that the hydrocarbon-contaminated soil under, the replaced pipelines was probably from Amoco’s line. Testing by Amoco’s own expert confirmed the oil around the replaced line — as well as the oil in the creek — was at least twenty years old, further evidence that the more recent leaks from Koch’s pipelines were not the source. Another Amoco employee also testified that, in 1974, Amoco routinely left oil in the soil around a pipeline after fixing a leak.' Occasionally, Amoco would excavate the contaminated soil, replace it with clean soil, and then spread (land farm) or deposit the contaminated somewhere else on the property. Given this practice, the Bowens argued a contaminated area of soil away from the replaced line was the ■ location where Amoco deposited excavated soil after the 1950 replacement.
Although Amoco changed its initial theory and admitted its lines might be the source of contamination in the soil, it continued to claim no responsibility for the hydrocarbon contamination in the creek. Admitting a small two-barrel leak may have occurred in 1952, Amoco continued to deny any connection to the contamination in the creek. Amoco contended that, despite the contamination in the soil around its pipelines, the hydrocarbon levels in the *930 groundwater did not exceed EPA standards, and because the pollution in the soil was not reaching the water table, it was not reaching the creek/ In addition, Amoco continued to refute the Bowens’ assertion that soil excavated from around the replaced line in 1950 was deposited in another location; although the record contains various characterizations of this site, Amoco appears to argue it is an old drilling site or the site of a historic pit used by others.
II. The Arbitration
The Bowens’ case was tried to a panel of three arbitrators in August 1999. The parties agreed to use the Rules for Non Administered Arbitration of Business Disputes (NABD), but they also agreed to modify these rules to expand the scope of judicial review. Specifically, the parties agreed that both would have the right to appeal any arbitration award to the district court within thirty days “on the grounds that the award is not supported by the evidence.” They also agreed that the district court’s ruling “shall be final.”
On October 18, 1999, the arbitration panel granted the following relief: (1) $3,032,000 to be deposited in an escrow fund for the use and benefit of a special master responsible for supervising the abatement of the contamination on the Bowens’ property; (2) $100,000 for the diminution in property value; (3) $1,200,000 for annoyance, inconvenience, and aggravation; (4) $1,000,000 in punitive damages; and (5) $41,000 for the costs of investigation and mitigation. One panel member dissented, objecting to the escrow fund for abatement and punitive damages award. Under the Federal Arbitration Act (FAA), 9 U.S.C. § 9, the Bowens then filed a motion for confirmation of the arbitration award in district court. Amoco responded by filing an objection to the confirmation and a motion to vacate the award. In addition, Amoco filed a notice of appeal of the arbitration award pursuant to the modified arbitration rules. Limiting its review to that provided under the FAA, the district court did not apply the parties’ expanded judicial standard of review and declined to vacate the award. The court granted the Bowens’ motion to confirm the award and affirmed the arbitrators’ order awarding the Bowens attorneys fees, costs, and arbitrators’ fees. Amoco appeals the district court’s order, urging us to vacate the entire award and remand for a new arbitration, or alternatively to vacate the remediation award and remand the case to district court for review based on the expanded standard of review.
II. Jurisdiction: Plaintiffs’ Motion to Dismiss Appeal
We must first address the Bowens’ motion to dismiss for lack of appellate jurisdiction. The Bowens contend the parties’ agreement that the district court’s “ruling shall be final” forecloses any appellate review. We disagree and deny the motion.
Under § 9 of the FAA, parties must express their intentions regarding judicial
confirmation of
an arbitration award in their arbitration agreements. 9 U.S.C. § 9. The statute contemplates judicial confirmation of arbitration awards only when “the parties in their agreement have agreed that a judgment of the court shall be entered upon the award made pursuant to the arbitration.”
Id.
We have held that this requires some language manifesting the parties’ intent — “either explicitly or implicitly” — to have judgment entered on the award.
Ok. City Assocs. v. Wal-Mart Stores, Inc.,
In addition, although parties to an arbitration agreement may eliminate judicial review by contract, their intention to do so must be clear and unequivocal.
See Dep’t of Air Force v. Fed. Labor Relations Auth.,
III. Standard of Review
In reviewing a district court’s decision concerning a motion to vacate an arbitration award, we review questions of law de novo.
Denver & Rio Grande W. R.R. Co. v. Union Pac. R.R. Co.,
Although the FAA does not create independent federal jurisdiction, the Supreme Court has held that the Act creates a body of substantive federal law governing arbitration agreements within its coverage.
Allied-Bruce Terminix Cos. v. Dobson,
Our review of the arbitration panel’s decision under the FAA is strictly limited; this highly deferential standard has been described as “among the narrowest known to the law.”
ARW Exploration Corp.,
Mindful of the strong federal policy favoring arbitration, a court may grant a motion to vacate an arbitration award only in the limited circumstances provided in § 10 of the FAA, 9 U.S.C. § 10, or in accordance with a few judicially created exceptions,
Denver & Rio Grande W. R.R. Co.,
*933 Amoco argues, however, that the parties in this case contracted for expanded judicial review in agreeing that the arbitration award would be appealable if “not supported by the evidence.” The district court did not apply this expanded standard, deciding instead that parties may not alter the traditional standards of review by contract. Emphasizing the policies behind the FAA, Amoco argues the district court erred and we should apply the contractually created standard. Although Amoco presents a difficult question, we conclude the purposes behind the FAA, as well as the principles announced in various Supreme Cases, do not support a rule allowing parties to alter the judicial process by private contract.
The only two circuits to definitively decide this issue have, however, held that private parties may agree to expand the judicial standard of review.

LaPine Tech. Corp. v. Kyocera Corp.,
In resolving conflicts among the FAA, state law, and parties’ agreements, the Supreme Court has repeatedly acknowledged that Congress’s intent in enacting the FAA was to ensure judicial enforcement of private arbitration agreements.
See, e.g., Mastrobuono v. Shearson Lehman Hutton, Inc.,
Guided by the FAA’s underlying purpose and the essentially contractual nature of arbitration, the Court has held, for example, that parties may agree to conduct arbitration under procedural rules different from the FAA.
Volt Info. Sciences, Inc.,
We disagree, however, with the Fifth and Ninth Circuits’ conclusion that the Supreme Court precedent emphasizing the FAA’s primary purpose compels enforcement of contractual modifications of judicial review. Although the Court has emphasized that parties may “specify by contract the rules under which [ ] arbitration will be conducted,”
Volt Info. Sciences, Inc.,
Even
Volt,
the case often cited in support of contractually created standards of review, does not dictate this result. In determining whether the FAA pre-empted a state procedural rule, to which the parties had agreed by contract, the Court focused on whether the state rule conflicted with the federal policies and objectives of the FAA.
Unlike the contract clause at issue in Volt, the contract clause in this case threatens to undermine the policies behind the FAA. We would reach an illogical result if we concluded that the FAA’s policy of ensuring judicial enforcement of arbitration agreements is well served by allowing for expansive judicial review after the matter is arbitrated. The FAA’s limited review ensures judicial respect for the arbitration process and prevents courts from enforcing parties’ agreements to arbitrate only to refuse to respect the results of the arbitration. These limited standards manifest a legislative intent to further the federal policy favoring arbitration by preserving the independence of the arbitration process. Unlike § 4 of the FAA, which allows parties to petition a federal court for an order compelling arbitration “in the manner provided for in [the] agreement,” the provisions governing judicial review of awards, 9 U.S.C. §§ 10-11, contain no language requiring district courts to follow parties’ agreements.
Not surprisingly, the FAA’s narrow standards reflect the Supreme Court’s well-established view of the relationship between arbitration and judicial review: “[B]y agreeing to arbitrate, a party ‘trades the procedures and opportunity for review of the courtroom for the simplicity, informality, and expedition of arbitration.’ ”
Gilmer v. Interstate/Johnson Lane Corp.,
Moreover, expanded judicial review places federal courts in the awkward position of reviewing proceedings conducted under potentially unfamiliar rules and pro
*936
cedures.

Under either expanded legal or expanded factual standards, the reviewing court would be engaging in work different from what it would do if it had simply-heard the case itself.
Lapine,
Although we are the first circuit to hold that parties may not contract for an expanded standard of review, two circuits have indicated they too would reject contractually expanded standards. In dicta, both the Seventh and Eighth Circuits have expressed disapproval of contractually expanded standards of review, acknowledging the independence of the arbitration process and noting parties may contract for an appellate arbitration panel should they desire more review.

IV. Arbitration Panel’s Jurisdiction to Order Abatement
Under Oklahoma statutes, the Oklahoma Corporation Commission (OCC) is vested with “exclusive jurisdiction” over many activities and properties affected by oil and gas, including “construction and operation of pipelines and associated rights-of-way” and related site remediation. Okla. Stat. Ann. tit. 17, § 52(A)(1)(h) & (A)(2); Okla. Stat. Ann. tit. 52, § 139(B)(2). Amoco argues that this statute abrogates the arbitration panel’s jurisdiction over the Bow-ens’ equitable request for abatement of the hydrocarbon contamination. Amoco argues that, because the arbitration panel did not have jurisdiction to order cleanup, they exceeded their powers and acted in manifest disregard of the law.
We have recognized the well-settled rule that any doubt about the arbitrability of an issue should be resolved in favor of arbitration and that arbitrators have broad authority in fashioning remedies: “Parties who agree to submit matters to arbitration are presumed to agree that everything, both as to law and fact, necessary to render an ultimate decision is included in the authority of the arbitrators .”
Ormsbee Dev. Co. v. Grace,
Furthermore, what “exclusive jurisdiction” means under the Oklahoma statutes is not entirely clear. The language is the product of several 1993 amendments and no post-amendment case squarely addresses its meaning. The Bowens argue that “exclusive jurisdiction” only refers to the OCC’s jurisdiction relative to other agencies, not courts. Case law prior to 1993 provides some support for this argument. Prior to 1993, the Oklahoma Supreme Court held that the OCC’s exclusive jurisdiction over certain oil and gas activities was implicit in the statute and precluded other
agency
review.
Matador Pipelines, Inc. v. Okla. Water Res. Bd.,
But Oklahoma courts have not yet decided that a district court lacks all jurisdiction to order a cleanup when the OCC has not yet exercised its jurisdiction. The case cited by Amoco,
Schneberger v. Apache Corp.,
Furthermore, the Oklahoma Supreme Court has applied the public-rights doctrine as articulated by the U.S. Supreme Court in determining how to apportion jurisdiction between the OCC and the district courts.
Tenneco Oil Co. v. El Paso Natural Gas Co.,
Citing
Tenneco,
we have held that an action under Oklahoma law to recover damages to property and water caused by the drilling of an oil well is a private rights dispute properly within the jurisdiction of the district court.
Marshall v. El Paso Natural Gas Co.,
V. Double Recovery: Damages and Abatement
Even if the arbitration panel had jurisdiction to grant injunctive relief, Amoco argues the three-million-dollar escrow fund is in manifest disregard of Oklahoma law, which prohibits double recovery for the same injury and limits monetary damages to the diminished value of the land.
See Schneberger,
In addition to awarding $100,000 in damages for the diminished value of the Bowens’ land, the arbitrators also set up a three-million-dollar escrow fund for the abatement of the nuisance. Amoco argues that the two awards constitute double recovery in manifest disregard of state law. Conversely, the Bowens argue the escrow fund is an equitable remedy facilitating *939 cleanup rather than an award of damages constituting double recovery under Oklahoma law. We agree that the escrow fund is an equitable remedy, rather than a legal award of damages. The arbitration panel appointed a special master to administer the funds and oversee the abatement plan, which must be submitted to the OCC for approval. Should the abatement cost less than expected, Amoco will receive any remaining funds. Because Oklahoma cases precluding double recovery do not explicitly address equitable remedies, the arbitration panel did not act in manifest disregard of state law. 9
Although Amoeo’s legal arguments are not without merit, the written order for the arbitration award does not reveal that the arbitrators deliberately disregarded Oklahoma law. Short of some evidence of “willful inattentiveness to the governing law,” we may not question their conclusions.
ARW Exploration Corp.,v. Aguirre,
In addition, we have observed that “courts favor the arbitrator’s exercise of [ ] broad discretion in fashioning remedies .”
Campo Machining Co. v. Local Lodge No.1926,
VI. Punitive Damages
Amoco also contends the arbitration panel lacked the authority to award punitive damages and, alternatively, awarded punitive damages in manifest disregard of Oklahoma law. In addition, Amoco argues the limited judicial review of the punitive damages awarded by the arbitration panel violates due process. We disagree with all three arguments.
The first argument, that the panel exceeded its powers in awarding punitive damages, is without merit in light of the Supreme Court’s decision in
Mastrobuono v. Shearson Lehman Hutton, Inc.,
Amoco’s contention that the arbitrators acted in manifest disregard of Oklahoma law in awarding punitive damages is also without merit. First, state statutory law provides limitations on exemplary damages awarded by a jury and does not clearly address arbitration awards. Okla. Stat. Ann. tit. 23, § 9.1. Second, one subsection of the statute allows a jury to award exemplary damages beyond the limitations provided in other subsections when the jury concludes the “defendant has acted intentionally and with malice toward others.” Id. § 9.1(D)(1). As the panel’s written order reflects, the arbitrators awarded punitive damages based on several factors, including Amoco’s egregious conduct prior to and after the discovery of contamination, Amoco’s awareness and blatant disregard of the pollution, and Amoco’s concealment of the pollution from the Bowens and the OCC. In light of these findings, we conclude the arbitration panel did not act in manifest disregard of the law in awarding punitive damages. 10
Finally, we disagree with Amoco’s contention that the limited judicial review of punitive damage awards by arbitrators violates due process. As we have already discussed at length, Amoco not only voluntarily entered into arbitration, but also petitioned the district court to compel arbitration. Before asking the district court to compel arbitration, Amoco was aware that the Bowens’ cause of action included a claim for exemplary damages. In addition, Amoco agreed to be governed by the broad language in the arbitration rules authorizing the granting of “any remedy or relief.” Amoco may not now oppose the very process it advocated and to which it voluntarily submitted.
See Todd Shipyards Corp. v. Cunard Line, Ltd.,
*941 We recognize, of course, that this case presents the unique situation in which the parties contracted for an expanded judicial standard of review, which was later invalidated. When the parties agreed to arbitrate all claims, including the punitive damages claim, they also agreed to the added security of a broader scope of judicial review. Our response to this concern is twofold. First, Amoco petitioned the district court to compel all claims to arbitration before agreeing to an expanded judicial standard of review; the Bowens’ claim for exemplary damages did not therefore deter Amoco from arguing the entire matter should be submitted to arbitration. Second, because the arbitration rules adopted by the parties required the arbitration panel to detail the reasoning behind the award, NABD R. 13.2, even our limited review has produced ample evidence in support of the panel’s award of punitive damages.
We therefore AFFIRM the district court’s confirmation of the arbitration award.
Notes
. In 1918, the predecessors in interest of both parties entered into a right-of-way agreement, which contained an arbitration provision. This agreement, which governed the grant of a pipeline easement, was ratified in 1943 by a second agreement.
. In February 1996, in preparation for the OCC pollution abatement group, Fred Hesser circulated a memo requesting information on repairs made to the line in 1950. The OCC’s memo, dated September 1996, however, contains no mention of a 1950 line replacement in summarizing the information Amoco had disclosed thus far. Based on the record, Amoco appears not to have disclosed this information in any subsequent communication with the OCC. Although the extent and timing of Amoco’s knowledge is unclear, the lack of records and the delay in locating even minimal information raise concerns. Other incidents in the record also raise concerns about Amoco's litigation tactics. In a memo concerning a ground penetrating radar report conducted by Amoco, an Amoco employee indicated he had contacted someone about obtaining historical geological data but "management had ordered them to get rid of anything that might cause someone to have any interest in the area in the future. As a result, there was no remaining geological information." Amoco did not produce this report, which supports some of the Bowens’ contentions, until the arbitration hearing was underway. Amoco argues that this memo was directed at the geological department and therefore proves nothing regarding its record-keeping practices in the pipeline department. We mention it here as but one example among several that demonstrate Amoco’s less than forthcoming approach to this entire matter.
. The public policy exception is not available in this case because it applies specifically to contract disputes. Under this exception, a court determines “whether the specific terms contained in [the contract] violated public policy by creating an explicit conflict with other laws and legal precedents.”
Seymour v. Blue Cross/Blue Shield,
. In an unpublished opinion, the Fourth Circuit also agreed with the Fifth Circuit, concluding the district court should have applied the expanded standard of review.
Syncor Int'l Corp. v. McLeland, 120
F.3d 262,
. In considering issues involving arbitration of collective bargaining agreements, the Court has often cautioned that courts should not second-guess an arbitrator's decision.
See, e.g.,
W.R.
Grace & Co. v. Local Union 759,
. We recognize, of course, that even under expanded standards of review, arbitration reduces the burden on district courts. Without an independent basis for federal court jurisdiction, the parties could not petition the district court to compel arbitration or to enter judgment on an award.
See Lapine,
. In addition, expanded judicial review would require arbitrators to issue written opinions with conclusions of law and findings of fact, further sacrificing the simplicity, expediency, and cost-effectiveness of arbitration. Rather than providing a single instance of dispute resolution with limited review, arbitration would become yet another step on the ladder of litigation. The drafters of the Revised Uniform Arbitration Act (RUAA) recognized these concerns, noting that expanded judicial review would allow parties a " 'second bite at the apple' on the merits [which] effectively eviscerates arbitration as a true alternative to traditional litigation.” RUAA § 23, cmt. B.l. Given these concerns, as well as others, the drafters chose not to adopt a provision for ''opt-in' review,” which would permit parties to agree by contract for expanded judicial review.
.The Seventh Circuit suggested parties may not contract for expanded judicial standards of review because "federal jurisdiction cannot be created by contract.”
Chicago Typographical Union,
.
The dissenting arbitrator raised yet another issue regarding the escrow fund. He argued the escrow fund is not what it appears. Although the majority set up the fund in order to “abate” the nuisance, the dissenter argued no present nuisance exists so the fund is really a damages award for cleanup of a historic pipeline leak. But although some Oklahoma precedent supports the dissenting arbitrator's position, contrary precedent also supports the majority arbitrators' approach.
Compare Atchison T. & S.F. Ry. Co. v. Kelly,
. In addition, the Oklahoma statute provides for punitive damages in the amount of actual damages when the jury concludes the defendant acted recklessly. Okla. Stat. Ann. tit. 23, § 9.1(B)(2). The panel’s award of $1,000,000 in punitive damages falls short of the $1,200,000 awarded for annoyance, inconvenience, and aggravation, which constitutes "a separate and distinct element of damage" under Oklahoma law.
Thompson v. Andover Oil Co.,
