BACKGROUND
Appellants were emрloyed at Laurans Standard Grocery Company (Laurans), in Cranston, Rhode Island, an unincorporated division of defendant-appellee R.W.F., Inc. (RWF), which also operаted a second division, Roger Williams Foods, Inc. (Roger Williams), a separate corporation, in Cumberland, Rhode Island. 1 Each division had a separate colleсtive bargaining agreement (CBA) with Teamsters Local 251.
After acquiring RWF in 1988, appellee Wetterau, Inc. announced plans to relocate the Roger Williams division operations outside of Rhode Island, and transfer the Roger Williams workers to the Laurans operation. RWF proposed to “dovetail” (i.e., integrate) the Roger Williams seniority list into the Laurans seniority list. The alternative would have been to “endtail” the Roger Williams workers; that is, treat them as new employees and eliminate their Roger Williams seniority. 2
After the workers at the Laurans plant . [collectively: LaRocque] filed a grievance protesting the “dovetailing” proposal, the matter was submitted to arbitration. The bаsic dispute that drove the arbitration was whether Laurans and Roger Williams were separate “employers” or whether RWF should be considered the “employer” of the workers at both divisions. Under both CBAs, the term “employer” was defined as the division; “seniority” as “continuous service with the Employer”; and RWF was not mentioned. The arbitrator found, nonethеless, that RWF was the
de facto
employer of the workers at both divisions, based on,
inter alia,
the history of RWF’s development, the shared administrative and executive operations of the two divisions, and the fact that “Laurans” was merely an unregistered trade-name, not a separate legal entity. LaRocque sought judicial review of the arbitral award in federal district court pursuant to 29 U.S.C. § 185, and the district court ultimately grаnted summary judgment directing enforcement.

DISCUSSION
The highly deferential standard governing judicial review of labor arbitration awards is described in
El Dorado Technical Servs., Inc. v. Union General de Trabajadores de Puerto Rico,
[A] court should uphold an award that depends on an arbitrator’s interpretation of a collective bargaining agreement if it can find, within the four corners of the agreement, any plausible basis for that interpretation.
(emphasis added; citations omitted).
See generally United Paperworkers Int’l Union v. Misco, Inc.,
1. The Scope of the Arbitral Submission.
Like many a party aggrieved by an arbitral award, LaRocque comes poorly сlad for the challenge, with only three appellate claims meriting brief discussion. First, La-Rocque contends that the award exceeded the scope of the аrbitrator’s authority, a claim that flies in the face of the joint arbi-tral submission:
Did RWF, Inc. violate the [CBAs] between the parties by proposing to dovetail the seniority lists of its employees under the Laurans Standard Agreement and its employees under the Roger Williams Agreement for competitive status seniority upon consolidating its regional operations? If so, what shall the remedy be?
Thus, the parties mutually agreed that the arbitrator should reconcile the language in the separate CBAs, neither of which afforded definitive guidance in the context of an unforeseen consolidation of the two divisions,
and determine an appropriate remedy. See Challenger Caribbean,
2. The Arbitrator’s Factual Findings.
LaRocque next insists that the arbitrator’s finding that RWF was the de facto employer of the workers at both locations is without evidentiary support. This tactic, too, is unavailing.
Few aggrieved parties surmount the deferential standard of judicial review accorded factual findings within the scope of an arbi-tral submission:
[T]he standard of review is unrelenting: as a general proposition, an arbitrator’s factual findings are not open to judicial challenge. Evеn if the arbitrator was seriously mistaken about some of the facts, his award must stand.
El Dorado,
3.The “No-modification” Clauses.
Finally, LaRocque points to purported curbs on the power of the arbitrator, as set forth in the CBAs: “the arbitrator shall not have the power to add to or subtract from or modify any provisions of the agreement.” These standard “no-modification” clauses,
see Local 1445, United Food & Commercial Workers Int’l Union v. Stop & Shop Cos.,
At the mutual invitation of the parties, the arbitrator was empowered to decide whether the proposal to “dovetail” the two seniority lists would violate the CBAs,
in the circumstances posed by the consolidation. See supra
at p. 97. After determining that the RWF proposal would not violate the CBAs,

CONCLUSION
The joint arbitral submission empowered the arbitrator to harmonize the parallel contract provisions in dispute and to fashion a remedy in light of the surrounding circumstances. As the arbitral award faithfully drew its essence from the collective bargaining agreements, it represents neither an arrogation of arbitral power, nor an impermissible modification. The district court judgment must be affirmed.
Affirmed.
Notes
. RWF was founded as a grocery distributor in 1945. In 1973, it branched out and created Laurans, which shared wаrehouse space with Roger Williams until 1987 when the Cranston facility opened.
. This case involves "competitive-status” seniority lists, which determine the order in which workers are laid off and rehired. Thus, "endtail-ing” would have left the most senior Roger Williams worker with less seniority than the most junior Laurans worker.
