begins only once, when a claim first accrues. If the limitations period under § 2462 reset each day,, the statutory term “first” would have no operative force. In other words, the statute could just as easily state that the limitations period begins whenever “the claim accrues.”
Second, Sierra Club’s reliance on United States v. Jaynes, 75 F.3d 1493 (10th Cir. 1996), as well as its reliance on our unpublished decision in United Slates v. Shaw, 150 Fed.Appx. 863 (10th Cir.2005) are equally unavailing.- Those cases involved the distinct “continuing offense” doctrine in the criminal context. There, a “continuing offense” “is a term of art” that we generally avoid applying unless “the explicit language of the substantive criminal statute compels such a conclusion, or the nature of the crime involved is such that Congress must assuredly have intended that it be treated as.a continuing one.” Jaynes, 75 F.3d at 1506 (internal quotation marks omitted). More importantly, like Havens-, these cases did not concern the unique “first accrued” language of § 2462.
Lastly, Sierra Club points to a Fifth Circuit administrative appeal for the proposition that the beginning of the limitations period under § 2462 is extended as long as a violation continues. In Newell Recycling Co. v. EPA, the Fifth Circuit upheld an administrative determination that a claim against a recycling facility’s improper disposal of pollutants did not accrue until the facility properly disposed of the contaminated soil. 231 F.3d 204, 206-07 (5th Cir. 2000). As a result, the limitations period under § 2462 did not begin to run until the proper disposal, ie., the end of the violation. Id. at 206. We find this holding unpersuasive. First, the court deferred to the interpretation of the administrative board and-, did not undertake a de novo review of the statute. Second, the board’s reasoning that no claim “accrued” until the violative conduct ended is inconsistent with more recent. Supreme Court cases that hold a claim accrues “when the plaintiff can file suit and obtain relief.” Heimeshoff, 134 S.Ct. at 610 (internal quotation marks omitted); see also Gabelli, 133 S.Ct. at 1220 (“[A] claim accrues when the plaintiff has a complete and present cause of action.” (internal quotation marks omitted)). Finally, the court nowhere addressed the significance of the phrase, “first accrued,” in § 2462. Thus, to the extent that Newell suggests the limitations period under § 2462 does not begin to run as long as an already-ripe violation continues, we disagree.
As a final note, we have observed that “the continuing violation doctrine is premised on the equitable notion that the statute” of limitations should not begin to run until a reasonable person would be aware that his or her rights have been violated.”
Davidson v. Am. Online, Inc., 337 F.3d 1179, 1184 (10th Cir.2003) (internal quotation marks omitted). It follows that , “a continuing violation claim fails if the plaintiff knew, or through the exercise of reasonable diligence would have known” of the injury when it began.
Id. at 1184 (internal quotation marks omitted). Here, nothing prevented Sierra Club from discovering, within five years, that it had an actionable claim as soon as OG & E began construction.
7In sum, § 2462 requires that a suit be filed within five years of when a claim first accrues, which in this case was when OG & E commenced modification of the boiler.

We express no opinion on OG & E’s exposure to civil penalties had a timely suit been commenced. See 42 U.S.C. § 7413 (allowing civil penalties for each day of violation of the CAA). We only hold that Sierra Club knew it had a cause of- action when OG & E commenced construction.
