PER CURIAM:
The Energy Reorganization Act of 1974 provides employees with a cause of action
when discharged in retaliation for reporting nuclear safety concerns. 42 U.S.C. § 5851. Yet
Congress conditioned that right on timeliness: a retaliation complaint must be filed with
the Occupational Safety and Health Administration (“OSHA”) within 180 days of the
alleged violation. See id. § 5851(b)(1); 29 C.F.R. § 24.103(c). However, “[t]he time for
filing [such] a complaint may be tolled for reasons warranted by applicable case law.” 29
C.F.R. § 24.103(d)(2).
Here, after Gregory Hanna’s former employer, Global Nuclear Fuel-Americas, LLC
(“GNF”), terminated him in 2017, he filed a complaint with OSHA alleging that GNF
terminated him in retaliation for raising significant safety concerns. But Hanna did not file
his complaint until after the statutory 180-day deadline had passed.
Rejecting Hanna’s tolling arguments, OSHA, an Administrative Law Judge, and the
Administrative Review Board (“Board”) each dismissed the complaint as untimely. “We
review the [Board]’s decision pursuant to the Administrative Procedure Act. Under that
framework, we may only disturb the [Board]’s decision if it was arbitrary, capricious, an
abuse of discretion, or otherwise not in accordance with law.” Peck v. U.S. Dep’t of Lab.,
Admin. Rev. Bd., 996 F.3d 224, 228 (4th Cir. 2021) (cleaned up). As relevant here, “[w]e
review an agency’s decision to deny equitable tolling for abuse of discretion.” Prince v.
Solis, 487 F. App’x 773, 774 (4th Cir. 2012) (per curiam); see Am. Bankers Ins. Grp., Inc.
v. Long, 453 F.3d 623, 629 (4th Cir. 2006).

Before this Court, Hanna contends that he can invoke equitable estoppel because
GNF lulled him into thinking his termination would be reversed. But Hanna does not
dispute the Board’s conclusion that GNF “did not actively or intentionally lull [him] into
forgoing his right[]” to file a timely OSHA complaint, which the Board concluded was
“supported by substantial evidence and unchallenged on appeal.” J.A. 976–77 (emphasis
added). * Instead, he relies on Board case law permitting tolling where “the [employer]’s
conduct, innocent or not, reasonably induced the plaintiff not to file suit within the
limitations period.” In re Hyman v. KD Res., ARB No. 09-076, ALJ No. 2009-SOX-020,
2010 WL 1260209, at *4 (A.R.B. Mar. 31, 2010) (emphasis added). However, our own
case law forecloses Hanna’s argument.
“The separation of powers doctrine requires administrative agencies to follow the
law of the circuit whose courts have jurisdiction over the cause of action. In the absence of
a controlling decision by the Supreme Court, the respective courts of appeals express the
law of the circuit.” Hyatt v. Heckler, 807 F.2d 376, 379 (4th Cir. 1986). And, in the precise
context of an Energy Reorganization Act retaliation complaint, we have held that an
employee may not invoke equitable estoppel “[a]bsent evidence that the employer acted to
deceive the employee as to the existence of its claim or otherwise to mislead or coerce the
employee into not filing a claim in a timely fashion.” English v. Whitfield, 858 F.2d 957,
963 (4th Cir. 1988). We further clarified that “an employee’s hope for a continuing
employment relationship” and “even an employer’s confirmation of that hope” is not
*
“J.A.” refers to the Joint Appendix filed by the parties in this matter.

enough to invoke equitable estoppel “absent some indication that the promise was a quid-
pro-quo for the employee’s forbearance in filing a claim.” Id. (cleaned up).
Thus, Hanna’s argument for estoppel—that GNF lulled him into a false sense of
security by “le[ading] [him] to believe that it was quite possible he could continue to work
at GNF if he followed proper procedure” and pursued internal appeals of his termination,
Opening Br. at 18—is foreclosed by English.
Accordingly, we deny the petition for review. We dispense with oral argument
because the facts and legal contentions are adequately presented in the materials before this
Court and argument would not aid the decisional process.
