EID, Circuit Judge. _________________________________

In 2021, HollyFrontier Cheyenne Refining, LLC (“HollyFrontier”) transitioned

a petroleum refinery into a renewable diesel production facility. As part of that

transition, HollyFrontier reassigned work from hourly workers to salaried employees

with higher levels of education and technical expertise. A Pennsylvania labor

organization—United Steel, Paper and Forestry, Rubber, Manufacturing, Energy,

Allied Industrial and Service Workers International Union Local 11-574 (the

“Union”)—filed a grievance against HollyFrontier, alleging that HollyFrontier’s

reassignment of work violated the parties’ collective bargaining agreement. After an

arbitrator resolved that issue in HollyFrontier’s favor, it concluded separately that the

salaried employees must be included in the bargaining unit—an issue that neither

party submitted for arbitration. HollyFrontier petitioned to vacate the arbitrator’s

decision, arguing the arbitrator had no authority to order the parties to include

salaried employees in the bargaining unit because the parties did not submit that issue

for arbitration. The district court granted HollyFrontier’s petition.

The Union now appeals the district court’s vacatur, claiming the arbitrator

acted within the scope of his authority when he determined that the salaried

employees must be included in the bargaining unit. We disagree. Based on the plain

2 Appellate Case: 23-8046 Document: 71-1 Date Filed: 03/25/2025 Page: 3

language of the parties’ briefs during arbitration, the parties limited the arbitrator’s

authority to resolution of only one issue: whether HollyFrontier’s reassignment of

work from hourly workers to salaried employees violated the parties’ collective

bargaining agreement. Because the arbitrator exceeded the bounds of his authority

by resolving a question not submitted for arbitration, we affirm the district court’s

decision to vacate the arbitration award.

I.

HollyFrontier operates an industrial refinery (the “Facility”) in Cheyenne,

Wyoming. Before this litigation, HollyFrontier employed hourly workers—called

“Lab Technicians” and “Lab Testers”—to assist in the refinement and production of

petroleum products, such as gasoline and diesel fuel. Together, the Facility’s Lab

Technicians and Lab Testers formed a bargaining unit, which was represented by the

Union. Both HollyFrontier and the Union are parties to a collective bargaining

agreement (the “CBA”), which requires the arbitration of certain grievances. The

CBA also places certain limitations on arbitration via its “challenged provisions”

clause, which provides that “[t]he sole authority of the arbitrator is to render a

decision as to the interpretation and/or application of the challenged provision(s) of

[the CBA.]” App’x Vol. II at 242.

In 2021, HollyFrontier transitioned the Facility from a petroleum refinery to a

renewable diesel production facility, which produces diesel fuel from vegetable

products. As part of that transition, HollyFrontier laid off many Lab Technicians and

Lab Testers, claiming the Facility no longer required their services. HollyFrontier

began to rely more heavily on those holding a salaried position—the position of

“Chemist”—which was made available only to individuals with degrees in chemistry.

The Union then filed a grievance against HollyFrontier, alleging that HollyFrontier

had violated the CBA by assigning Chemists work that was previously performed by

Lab Testers.

After several failed attempts to resolve the Union’s complaint, the parties

submitted the issue for arbitration. The Union presented the issue as whether

HollyFrontier “violate[d] the [CBA] when they replaced bargaining unit employees

with salaried personal [sic] to preform [sic] laboratory work[,]” App’x Vol. I at 93,

and asked that HollyFrontier “cease and desist from using salaried employees in the

lab,” id. at 98. HollyFrontier framed the issue similarly: It wanted the arbitrator to

determine whether HollyFrontier had violated the CBA “by determining the work,

methods, processes, assignment of work, work duties, the qualifications of the

employees and the staffing requirements” for the Facility. Id. at 190. In April 2022,

the arbitrator resolved the issue, concluding that the CBA did not prohibit

HollyFrontier from replacing Lab Testers with Chemists.

The arbitrator then determined—without a request from either party—that “the

parties need[ed] to have discussion to determine whether or not the Chemist position

is to be within the bargaining unit or outside the bargaining unit.” Id. at 133. After

post-arbitration meetings between HollyFrontier and the Union failed, and under

HollyFrontier’s protest, the parties returned to arbitration on the issue of whether

Chemists were members of the bargaining unit. In November 2022, after briefing

4 Appellate Case: 23-8046 Document: 71-1 Date Filed: 03/25/2025 Page: 5

and argument on this new issue, the arbitrator determined that the bargaining unit

represented by the Union must include Chemists.

HollyFrontier petitioned to the district court to vacate the arbitration award,

arguing the arbitrator exceeded his authority by deciding a question the parties did

not submit for resolution. The district court agreed, reasoning that the arbitrator’s

“sole authority was to render a decision as to the interpretation and/or the application

of the challenged provision(s) of the [CBA].” App’x Vol. II at 391 (quotation

omitted). The court noted that the Union itself had framed the issue as “whether

[HollyFrontier] violated the CBA when they replaced bargaining unit employees with

salaried personnel to perform laboratory work.” Id. at 392 (quotation omitted). And
