OPINION OF THE COURT
Trucking companies Fast Rig Support, LLC and First Americans Shipping and Trucking, Inc., (collectively, “Defendants”), appeal the stipulated judgment requiring them to pay Plaintiffs overtime. Because the District Court correctly determined that Defendants have not met their burden to show that the Motor Carrier Act (“MCA”) exemption to the overtime provisions in the Fair Labor Standards Act (“FLSA”) and Pennsylvania Minimum Wage Act (“PMWA”) applies, see 29 U.S.C. § 207(a)(1); 43 Pa. Stat. Ann. § 333.104(c), we will affirm.
I
Plaintiffs, including Alphonse Mazzarel-la, worked for Defendants as truck drivers. They transported water to hydraulic frack-ing sites within Pennsylvania.
Before trial was scheduled to begin, the District Court ordered the parties to submit briefing on whether the Defendants were subject to the MCA exemption to the FLSA’s overtime requirements. As explained infra, the MCA provides that certain interstate employment activity that is subject to the jurisdiction of the Department of Transportation is exempt from certain requirements, such as the FLSA’s overtime provisions.
In support of applying the MCA, Defendants explained that they contract with gas-drilling companies to transport water from “retention ponds” to drill sites for hydraulic fracking. Defendants assert that after fracking is completed, they are occasionally hired to transport the water used in the fracking process to injection wells for disposal. Although Defendants presented detailed arguments about the fracking process in their briefs, they submitted no evidence on this topic. Rather, Defendants submitted only: (1) a certificate issued by the Department of Transportation authorizing Defendant First Americans to “engage in transportation as a common carrier of property ... in inter
The District Court held that the water Defendants transported constituted property for purposes of applying the MCA, but that Defendants had not shown the water and drivers were engaged in a “continuous stream of interstate travel.” App. I at 16-17. The District Court noted that its own research disclosed that water involved in the fracking process becomes “contaminated,” App. I at 18, and “substantially modified,” and thus Defendants were engaged in “two separate commercial transactions,” one before the water becomes “tainted” and one after the fracking process is complete, leading to the conclusion that there was no continuous movement of an unaltered item across state lines and “insufficient evidence of interstate intent” on Defendants’ part to apply the MCA exemption, App. I at 20-21.
The parties agreed to the entry of a conditional judgment awarding Plaintiffs $31,000, which allowed Defendants to appeal the ruling precluding them from relying on the MCA exemption.

The FLSA generally mandates that employers pay employees 150% of their hourly wage for all time worked above forty hours per week.
FLSA exemptions must be construed narrowly against the employer, and Defendants “bear[ ] the burden of proving ‘plainly and unmistakably’ that the drivers qualify for the MCA exemption.” Packard
Here, to demonstrate that their employees are engaged in interstate commerce under the MCA exemption, Defendants must similarly show that the drivers’ transportation of water is part of a “continuous stream of interstate travel.” Walters v. Am. Coach Lines of Miami, Inc.,
In this case, none of the three pieces of evidence Defendants produced demonstrate that their drivers were involved in a continuity of movement in interstate commerce. The DOT certificate merely authorizes Defendants to engage in interstate transportation. It provides no information about whether Defendants’ drivers actually drove across state lines or otherwise engaged in interstate commerce.
Beyond this limited evidence, Defendants present only bare assertions, without evidentiary support in the record, about the fracking process and transportation in interstate commerce. For instance, Defendants assert in their brief that water is sometimes picked up from sites in New York rather than Pennsylvania, and Defendants are sometimes contracted to haul wastewater to Ohio. This assertion, however, is not backed up with evidence. Moreover, even if the Defendants presented evidence supporting these assertions, it would not, by itself, demonstrate that their actions are a “clearly identifiable element of an integrated interstate distribution system.” Packard,
The details of a business’s operation are often critical to determining the connection between an employee’s actions and interstate commerce. See, e.g., Morris v. McComb,
In short, Defendants have simply not met their burden to “plainly and unmistakably” show that the MCA exemption applies. Friedrich,

For the foregoing reasons, we will affirm the order of the District Court.
Notes
. Although Defendants assert that "[i]n many instances, the drivers do leave the Commonwealth of Pennsylvania during the ordinary course of their employment,” App. II at 15, they do not deny that their drivers' primary responsibilities involved the transportation of water within Pennsylvania itself, and as discussed further herein, provide no evidence to substantiate the claim that the drivers leave Pennsylvania as part of their duties.
. The parties stipulated to the conditional certification of a collective FLSA action, and Plaintiffs withdrew their class action claims under the PMWA.
. Defendants’ notice of appeal seeks review of "the final judgment entered in this action.” App. I at 1. However, based upon the arguments presented in the parties' briefs and the contents of the stipulated judgment, we understand the parties are seeking review of the District Court’s order that held the MCA exemption did not apply.
. The District Court had jurisdiction over Plaintiffs’ FLSA claim pursuant to 29 U.S.C. § 216(b) and 28 U.S.C. § 1331, and the PMWA claim pursuant to 28 U.S.C. § 1367, and we have jurisdiction over this appeal pursuant to 28 U.S.C. § 1291. The question of "[wjhether an employee’s particular activities excluded them from the overtime benefits of the FLSA is a question of law.” Resch v. Krapfs Coaches, Inc.,
.This analysis applies equally to the FLSA and PMWA claims, given the similarities between the MCA in each statute. See 29 U.S.C. § 213(b)(1) (FLSA exemption); 43 Pa. Stat. Ann. § 333.105(b)(7) (PMWA exemption); see also Resch,
. The District Court held that because the water had economic value to Defendants, it could be sufficiently considered property for purposes of applying the exemption. Neither party challenges that ruling on appeal.
. These regulations are persuasive but not binding in determining the scope of the MCA exemption and definition of interstate commerce. See Packard,
. The certificate itself references only that the authorization will continue "as long as the carrier maintains compliance” with insurance coverage and process server designation requirements, as well as a requirement that the carrier "render reasonably continuous and adequate service to the public.” App. II at 50.
. Defendants' brief states that this spreadsheet reflects the care with which they account for the water transported, and they contend this supports a finding of "interstate intent.” Appellant’s Br. 12. However, nothing in the spreadsheet provides a basis to infer Defendants intended to transport water recorded on the sheet out of state.
. The District Court noted the general insufficiency of the evidence Defendants presented, and apparently conducted its own research, concluding that the fact that water becomes "contaminated,” App. I at 18, and "tainted” during the fracking process sufficiently changed the character of the water to demonstrate that "defendants' trucking activities constitute two separate commercial transactions,” one involving delivery of the water, and the second picking up and transporting the water to Ohio, App. I at 20. The eviden-tiary record provided by the parties lacks facts from which we can reach this conclusion, and we decline to look outside the record to address it. See Fassett v. Delta Kappa Epsilon (N.Y.),
. Defendants argue that they meet this burden because their intent "from the very beginning of the water transportation journey — is to transport the water to the disposal wells out of state.” Appellant's Br. 13 (emphasis omitted). They, however, provide no evidence from which this intent can be gleaned. Moreover, the mere intersection of a company's activity and interstate commerce is not enough to warrant application of the MCA exemption. See Packard,
