Appeal from the United States District Court

for the Southern District of Florida

________________________

(August 31, 2020)

Before LUCK, ED CARNES and MARCUS, Circuit Judges.

MARCUS, Circuit Judge:

A provision of the Comprehensive Environmental Response, Compensation 

and Liability Act of 1980 (“CERCLA”), 42 U.S.C. § 9601 et seq., offers discovery 

tolling to plaintiffs injured by exposure to hazardous substances. This provision

Case: 18-15104 Date Filed: 08/31/2020 Page: 2 of 17
3

tolls the statute of limitations until a plaintiff knows (or reasonably should have 

known) her injury was caused by a hazardous substance, or until the plaintiff 

reaches the age of majority. See 42 U.S.C. § 9658(a)(1), (b)(4)(A), (B)(i). The 

appellants, Joselyn and Steve Santiago, seek the benefit of that tolling provision. 

Their daughter, Cynthia, tragically passed away from brain cancer at the age of 

twenty, and the Santiagos say that Pratt & Whitney exposed Cynthia to the 

radioactive chemicals that caused her fatal tumor to form. Because Cynthia filed

this lawsuit within months of turning eighteen and discovering the cause of her 

cancer, the Santiagos argue that their suit is timely. 

The central problem with their claim, however, is that CERCLA’s 

discovery-tolling provision is not available to them. By its own terms, that 

provision applies only to actions “brought under State law.” Id. § 9658(a)(1). But 

the Santiagos’ lawsuit is a public liability action brought exclusively under federal 

law -- the Price-Anderson Act, Pub. L. 85-256, 71 Stat. 576 (1957), as amended in 

1988. See 42 U.S.C. §§ 2014(hh), 2210(n)(2). These actions borrow their 

“substantive rules for decision” from the state where the incident occurred, and in 

this case, that means Florida’s four-year statute of limitations governs. Cynthia 

filed this lawsuit long after the expiration of that statute of limitations. Thus, we 

are required to hold that the Santiagos’ claims are untimely and affirm the 

judgment of the district court.

I.

The essential facts and procedural history are these. In 1996, when she was 

four months old, Cynthia Santiago moved with her family to a residential area 

known as the Acreage, in Palm Beach County, Florida. Near the Acreage --

around ten miles from Cynthia’s home -- is an undeveloped tract of land which 

Pratt & Whitney purchased in 1957.

1

 Pratt & Whitney conducted various research 

and development tests there, and over time, those tests contaminated the soil. By 

1993, most of the soil at the testing site required removal. Cynthia’s parents allege 

that between 1993 and 2000, Pratt & Whitney excavated tens of thousands of tons 

of contaminated soil. The soil was eventually transported and sold as “fill” for the 

construction and development of the Acreage community. The Santiagos also 

claim that runoff from the contaminated soil leached into the Acreage’s water 

supply.

In 2009, the Florida Department of Health found a cluster of pediatric brain 

cancer cases in the Acreage. The Santiagos say that the number of brain cancer 

diagnoses in the cluster was seven times greater than the background expectation. 

And they claim that there was less than a 1% chance the cluster would have formed 

1 Cynthia originally brought this suit against United Technologies Corporation (“UTC”), which 

has since merged with Raytheon Company to form Raytheon Technologies Corporation 

(“Raytheon”). On April 22, 2020, following the merger, UTC moved this Court to substitute 

Raytheon as the appellee. We granted the motion on May 4, 2020. Since UTC did, and 

Raytheon now does business under the name Pratt & Whitney, we’ll refer to the appellee as Pratt 

& Whitney.

on its own. One of the cases in the cluster, the Santiagos say, was Cynthia’s. In 

2009, at age thirteen, doctors diagnosed Cynthia with ependymoma, which the 

Santiagos characterized as a type of brain cancer that occurs most often in young 

children. The Santiagos assert that Pratt & Whitney caused Cynthia’s cancer by 

exposing her to the radioactive isotope thorium-230, referred to more formally as a 

radionuclide. Cynthia’s ependymoma metastasized to her spine in 2013, the 

Santiagos say. Doctors detected an amount of thorium-230 in Cynthia’s spine 

hundreds of times higher than would normally be expected, in fact multiple 

magnitudes greater than levels found even in a uranium miner.

Cynthia turned eighteen in March 2014 and filed suit against Pratt & 

Whitney in the United States District Court for the Southern District of Florida on

November 7, 2014. When she was deposed, Cynthia said she was unaware of any 

contamination in the Acreage until 2014, after she had spoken with an attorney. 

Cynthia tragically passed away from the cancer in 2016, at age twenty. The spinal 

tumor was recognized as the cause of her death.

After Cynthia died, the Santiagos, with leave of court, amended the 

complaint. The amended complaint appears to assert two Florida-law claims and 

one federal claim. The first state-law claim purports to allege wrongful death 

through negligence (Count I). The second state-law claim purports to allege 

Case: 18-15104 Date Filed: 08/31/2020 Page: 5 of 17
6

wrongful death through trespass (Count II).

2

 And the federal claim asserts

damages arising from a nuclear incident, pursuant to the Price-Anderson Act, 42 

U.S.C. § 2210(n)(2) (Count III).3

Pratt & Whitney moved for summary judgment, arguing, among other 

things, that the state wrongful-death claims based on negligence and trespass were 

subject to a four-year statute of limitations under Florida law, which began to 

accrue upon the diagnosis of Cynthia’s cancer on November 27, 2009.4

 Thus, the

2 The Santiagos say their state claims are “grounded in Florida common law.” As the Florida 

Supreme Court has recognized, however, wrongful-death actions are not available under Florida 

common law. See Toombs v. Alamo Rent-A-Car, Inc., 833 So. 2d 109, 111 (Fla. 2002) (“An 

action for wrongful death is a purely statutory right.”); Fla. E. Coast Ry. Co. v. McRoberts, 149 

So. 631, 632 (Fla. 1933) (“The common law afforded no remedy for death by wrongful act. 

Hence the right and the remedy are purely statutory.”). Instead, Florida’s Wrongful Death Act 

created a statutory cause of action for wrongful death, see Fla. Stat. § 768.19, “which was not 

recognized at common law.” Nissan Motor Co. v. Phlieger, 508 So. 2d 713, 714 (Fla. 1987).

3 In their amended complaint, the Santiagos recast Cynthia’s original claim for negligence, 

breaking it into two counts for negligence (Count I) and for trespass (Count II) under Florida 

law. They retained Cynthia’s Price-Anderson Act claim (Count III), and dropped Cynthia’s 

claim for strict liability under Fla. Stat. § 376.313. The Santiagos’ amended complaint added a 

fourth count arising under Florida’s civil RICO statute, Fla. Stat. § 772.101 et seq. The district 

court granted Pratt & Whitney’s motion to dismiss that claim. The Santiagos do not challenge 

that ruling on appeal.

4 The Florida statute of limitations provides:

Actions other than for recovery of real property shall be commenced as 

follows:

. . .

(3) Within four years. --

(a) An action founded on negligence.

. . . 

(g) An action for trespass on real property.

Fla. Stat. § 95.11.

Case: 18-15104 Date Filed: 08/31/2020 Page: 6 of 17

state claims, which were not brought by Cynthia until November 7, 2014 -- nearly 

five years after her diagnosis -- were untimely. As for the federal claim, Pratt & 

Whitney urged the district court to borrow the most analogous state-law claim’s 

statute of limitations (here, Florida’s four-year period for negligence and trespass). 

Accordingly, Pratt & Whitney said the federal claim was time barred as well.

The Santiagos raised several tolling arguments in the district court. Their 

primary argument, however, and the only one pursued in this appeal, relies on a

discovery-tolling provision found in CERCLA. The district court rejected the 

argument because their suit was a public liability action brought pursuant to the

exclusive provisions found in the federal Price-Anderson Act. In public liability 

actions, the courts are required to apply “the limitations period of the state where” 

the incident occurred -- here, Florida. 

This timely appeal followed.

II.

At the summary judgment stage, we “tak[e] all of the facts in the record and 

draw[] all reasonable inferences in the light most favorable to the non-moving 

party.” Peppers v. Cobb County, 835 F.3d 1289, 1295 (11th Cir. 2016). We 

review the district court’s order granting summary judgment to Pratt & Whitney de 

novo. Id. Likewise, we exercise de novo review over questions of statutory 

Case: 18-15104 Date Filed: 08/31/2020 Page: 7 of 17

interpretation. Barrientos v. CoreCivic, Inc., 951 F.3d 1269, 1276 (11th Cir. 

2020).

The Santiagos’ lawsuit is a public liability action arising under the PriceAnderson Act (“PAA”). Congress enacted the PAA in 1957 “to encourage the 

development of the atomic energy industry” while “protect[ing] the public” from 

injuries caused by “nuclear incidents.” 42 U.S.C. § 2012(i); see also Duke Power 

Co. v. Carolina Envtl. Study Grp., Inc., 438 U.S. 59, 64 (1978). Congress 

amended the PAA with the passage of the Price-Anderson Amendments Act of 

1988 (the “Amendments Act”), which created “an exclusive federal cause of action 

for radiation injury.” Roberts v. Fla. Power & Light Co., 146 F.3d 1305, 1306 

(11th Cir. 1998) (per curiam). The Amendments Act vested the federal courts with 

original jurisdiction over “any public liability action arising out of or resulting 

from a nuclear incident.” 42 U.S.C. § 2210(n)(2). The statute defined a “public 

liability action” as “any suit asserting public liability.” Id. § 2014(hh). Public 

liability, in turn, is defined as “any legal liability arising out of or resulting from a 

nuclear incident,” subject to certain exceptions not relevant here. Id. § 2014(w). 

The PAA directs the federal courts to borrow the “substantive rules for 

decision” in public liability actions “from the law of the State in which the nuclear 

incident involved occurs, unless such law is inconsistent with” federal law. Id. 

Thus, Florida law provides the applicable statute of limitations in this case. As 

Case: 18-15104 Date Filed: 08/31/2020 Page: 8 of 17
9

we’ve said, Florida law required Cynthia to file her lawsuit within four years of her 

cancer diagnosis. See Fla. Stat. § 95.11(3)(a), (g). Because she did not, her claims 

are time barred.

The Santiagos resist this conclusion. But they point us to no Florida law that 

tolls the statute of limitations. Instead, they rely on a discovery-tolling provision

found in a different federal statute, CERCLA, in 42 U.S.C. § 9658. Section 9658 

of CERCLA tolls state-law statutes of limitations until (1) “the date the plaintiff 

knew (or reasonably should have known) that” her “personal injury” was “caused 

or contributed to by” a “hazardous substance”; or (2) in “the case of a minor, the 

date on which the minor reaches the age of majority, as determined by State law.” 

42 U.S.C. § 9658(b)(4)(A), (B)(i). Under Florida law, the age of majority is 

eighteen. See Fla. Stat. § 743.07. The Santiagos say their lawsuit was timely 

because it was filed just months after Cynthia turned eighteen and discovered the 

cause of her cancer. CERCLA’s tolling provision, however, applies only to an

“action brought under State law for personal injury” which is “caused or 

contributed to by exposure to any hazardous substance.” Id. § 9658(a)(1). The 

trouble with the argument is that public liability actions cannot be “brought under 

State law,” as § 9658 requires. Because this action was instead brought

exclusively under federal law -- the PAA -- the Santiagos cannot avail themselves 

of CERCLA’s discovery-tolling provision.

We start with the plain meaning of the phrase “action brought under State 

law.” When confronted with a question of statutory interpretation, our first task is

to simply look at what the words say. As we have explained:

The first rule in statutory construction is to determine whether the 

language at issue has a plain and unambiguous meaning with regard to 

the particular dispute. We must presume that Congress said what it 

meant and meant what it said. In our circuit, when the import of the 

words Congress has used is clear we need not resort to legislative 

history, and we certainly should not do so to undermine the plain 

meaning of the statutory language.

Shotz v. City of Plantation, 344 F.3d 1161, 1167 (11th Cir. 2003) (alterations 

adopted) (ellipsis and quotations omitted). And when the language at issue is a 

legal term of art, the phrase’s “ordinary legal meaning is to be expected . . . . As 

Justice Frankfurter eloquently expressed it: ‘[I]f a word is obviously transplanted 

from another legal source, whether the common law or other legislation, it brings 

the old soil with it.’” Antonin Scalia & Bryan A. Garner, Reading Law: The 

Interpretation of Legal Texts 73 (2012) (alteration in original) (quoting Felix

Frankfurter, Some Reflections on the Reading of Statutes, 47 Colum. L. Rev. 527, 

537 (1947)).

Here, the phrase “brought under” is one of common legal parlance. Simply 

put, a suit is brought under the law which supplies its cause of action. And a cause 

of action creates, enables, and allows the litigation of a claim. See Cause of 

Action, Black’s Law Dictionary (11th ed. 2019) (defining “cause of action” as that 

Case: 18-15104 Date Filed: 08/31/2020 Page: 10 of 17
11

which “entitles one person to obtain a remedy in court from another person” or 

which “giv[es] rise to one or more bases for suing”). To “bring an action” means 

to “sue.” Bring an Action, Black’s Law Dictionary (11th ed. 2019). And to sue

“under” a law is to sue pursuant to, or as authorized by, the cause of action created

by that law. See Pursuant To, Black’s Law Dictionary (11th ed. 2019) (“As 

authorized by; under.” (emphasis added)). Thus, for example, the Supreme Court

has explained that the “vast majority of cases brought under the general federalquestion jurisdiction of the federal courts are those in which federal law creates the 

cause of action.” Merrell Dow Pharm. Inc. v. Thompson, 478 U.S. 804, 808 

(1986) (emphasis added).

With this in mind, we turn to the instant claims. Through the Amendments 

Act, Congress vested the federal courts with original jurisdiction over public 

liability actions. See 42 U.S.C. §§ 2014(hh), 2210(n)(2). Congress stated that 

each public liability action “shall be deemed to be an action arising under section 

2210 of this title.” Id. § 2014(hh). Our Court has unambiguously interpreted these 

provisions as creating an exclusive federal cause of action for nuclear incidents. 

See Roberts, 146 F.3d at 1306 (explaining that the Amendments Act created “an 

exclusive federal cause of action for radiation injury”). And we are hardly alone in 

this interpretation. See, e.g., Acuna v. Brown & Root Inc., 200 F.3d 335, 339 (5th 

Cir. 2000) (explaining that “Congress intended to create an exclusive federal cause 

Case: 18-15104 Date Filed: 08/31/2020 Page: 11 of 17
12

of action for torts arising out of nuclear incidents”); Corcoran v. N.Y. Power Auth., 

202 F.3d 530, 537 (2d Cir. 1999) (explaining that the Amendments Act created “an 

exclusive federal cause of action for radiation injury” (emphasis in original)). 

Thus, a public liability action can never be “brought under State law.” All 

public liability actions must be brought exclusively under federal law. As the 

Supreme Court has explained, the PAA “transforms into a federal action ‘any 

public liability action arising out of or resulting from a nuclear incident.’” El Paso 

Nat. Gas Co. v. Neztsosie, 526 U.S. 473, 484 (1999) (emphasis added) (quoting 42 

U.S.C. § 2210(n)(2)). A plaintiff can bring a public liability action as a “federal 

claim” under the PAA “or not at all.” Nieman v. NLO, Inc., 108 F.3d 1546, 1553 

(6th Cir. 1997); see also O’Conner v. Commonwealth Edison Co., 13 F.3d 1090, 

1099 (7th Cir. 1994) (“After the Amendments Act, no state cause of action based 

upon public liability exists. A claim growing out of a nuclear incident is 

compensable under the terms of the Amendments Act or it is not compensable at 

all.” (quoting In re TMI Litig. Cases Consol. II (TMI II), 940 F.2d 832, 854 (3d 

Cir. 1991))). In other words, “state regulation of nuclear safety . . . is preempted 

by federal law.” Roberts, 146 F.3d at 1308 (quoting O’Conner, 13 F.3d at 1105).

That conclusion brings us to the end of our analysis: the Santiagos’ claims 

are time barred. We know that the Santiagos’ lawsuit is a public liability action 

because they have alleged “legal liability arising out of or resulting from a nuclear 

Case: 18-15104 Date Filed: 08/31/2020 Page: 12 of 17
13

incident” -- specifically, they claim injury arising from exposure to thorium. See

42 U.S.C. § 2014(w), (hh); see also id. § 2014(q), (z) (defining “nuclear incident” 

as “any occurrence” causing “bodily injury, sickness, disease, or death” that arises 

out of or results “from the radioactive, toxic, explosive, or other hazardous 

properties” of any “source” material, including thorium). We also know that the 

Santiagos brought their public liability action -- just like all plaintiffs bring all 

public liability actions -- exclusively under federal law. Thus, the Santiagos 

cannot avail themselves of CERCLA’s tolling provision. Instead, as the district 

court properly found, the PAA points us to Florida law for the applicable statute of 

limitations. And under Florida law, Cynthia’s claims are untimely.

The PAA’s broader statutory context and its unmistakable purpose fully 

support the conclusion we reach. Looking first to statutory context, we note that 

elsewhere in the PAA, Congress expressly contemplated discovery tolling. Thus, 

for claims arising from an “extraordinary nuclear occurrence,” Congress allowed 

for tolling “within three years from the date on which the claimant first knew, or 

reasonably could have known, of his injury or damage and the cause thereof.”5

 42 

U.S.C. § 2210(n)(1). Since Congress knew how to provide for discovery tolling --

but chose not to -- the “familiar ‘easy-to-say-so-if-that-is-what-was-meant’ rule of 

statutory interpretation has full force here. The silence of Congress is strident.” 

5 It is undisputed that Cynthia’s injury was not the result of an “extraordinary nuclear occurrence.”

Case: 18-15104 Date Filed: 08/31/2020 Page: 13 of 17
14

Scalia & Garner, Reading Law at 181–82 (quoting Comm’r v. Beck’s Estate, 129 

F.2d 243, 245 (2d Cir. 1942)). And “[w]here Congress includes particular 

language in one section of a statute but omits it in another section of the same Act, 

it is generally presumed that Congress acts intentionally and purposely in the 

disparate inclusion or exclusion.” Russello v. United States, 464 U.S. 16, 23 

(1983) (alteration adopted and quotation omitted); see also Va. Uranium, Inc. v. 

Warren, 139 S. Ct. 1894, 1900 (“In this, as in any field of statutory interpretation, 

it is our duty to respect not only what Congress wrote but, as importantly, what it 

didn’t write.”); Animal Legal Def. Fund v. U.S. Dep’t of Agric., 789 F.3d 1206, 

1217 (11th Cir. 2015) (“Where Congress knows how to say something but chooses 

not to, its silence is controlling.” (quotation omitted)). Had Congress wanted to 

displace state law by imposing discovery tolling for public liability actions, it knew 

how to say so, as it did elsewhere in the PAA.

The text and structure of the PAA undercuts the Santiagos’ argument that 

they might simultaneously bring their claims under both federal and state law. 

Though the Santiagos accept that their public liability action arises under federal 

law, they make much of the fact that public liability actions borrow their

“substantive rules for decision” from state law. 42 U.S.C. § 2014(hh). According 

to the Santiagos, this means public liability actions are also “brought under State 

law.” But the Amendments Act says that a “public liability action” is “any suit 

Case: 18-15104 Date Filed: 08/31/2020 Page: 14 of 17
15

asserting public liability.” Id. (emphasis added). And “public liability” is “any

legal liability arising out of or resulting from a nuclear incident,” subject only to 

exceptions not relevant here. Id. § 2014(w) (emphasis added). “As we have often 

had occasion to say, when interpreting a statute, ‘any’ means ‘all.’” United States 

v. Caniff, 955 F.3d 1183, 1190 (11th Cir. 2020) (per curiam); see also TMI II, 940 

F.2d at 854 (emphasizing that under § 2014(hh), a “‘public liability action’ 

encompasses ‘any legal liability’ of any ‘person who may be liable’ on account of 

a nuclear incident” and noting the “breadth of this definition” (emphases in 

original)). Congress left no room for the Santiagos’ argument -- instead, as we 

have explained, Congress directed that all public liability actions must be brought 

only under federal law.

Moreover, while public liability actions derive their “substantive rules for 

decision” from state law, they do so only to the extent “such law is [not] 

inconsistent with” federal law. 42 U.S.C. § 2014(hh). This express limitation on 

the incorporation of state law in public liability actions underscores that those 

actions are federal in nature, regardless of the source of law Congress chose to 

borrow. We emphasized in Roberts that a PAA claim is a wholly federal cause of 

action in an area Congress earmarked as “the exclusive business of the Federal 

Government,” even though the statute incorporates some state law. Roberts, 146 

F.3d at 1308 (quoting Pac. Gas & Elec. Co. v. State Energy Res. Conservation & 

Case: 18-15104 Date Filed: 08/31/2020 Page: 15 of 17
16

Dev. Comm’n, 461 U.S. 190, 208 (1983)). And while we did describe public 

liability actions in Roberts as “hybrid actions,” id. at 1307, to say a public liability 

action is a “hybrid” is not to say it is simultaneously brought under both federal 

and state law. Rather, this reflects only the simple premise that a public liability 

action derives its substantive rules for decision from state law, and even then only 

to the extent consistent with federal law. 

The United States Court of Appeals for the Eighth Circuit reached the same 

result in Halbrook v. Mallinckrodt, LLC, 888 F.3d 971 (8th Cir. 2018). There, the 

court considered the plaintiffs’ “wrongful-death claims under the public-liability 

provision of the” PAA. Id. at 973. Missouri law, like Florida law here, did not 

allow “application of a discovery rule.” Id. And the court concluded that 

CERCLA’s discovery-tolling provision did not apply, since a public liability action 

is brought under federal, rather than state, law. Id. at 977–78. The Eighth Circuit 

reasoned that “Congress spoke clearly when stating” a public liability “‘action 

shall be deemed to be an action arising under’ federal law.” Id. at 977 (quoting 42 

U.S.C. § 2014(hh)). Thus, it concluded, “CERCLA’s provisions governing actions 

brought under state law are inapplicable to” public liability actions brought under 

the PAA. Id. at 978.

The statute’s unmistakable purpose is fully consonant with this conclusion. 

It is beyond dispute that Congress intended for the federal government, and not the 

Case: 18-15104 Date Filed: 08/31/2020 Page: 16 of 17
17

states, to have control over issues of nuclear injury. As we have observed,

Congress “established a comprehensive federal framework governing the nuclear 

power industry” and “granted the federal government a monopoly on the 

development of nuclear power.” Roberts, 146 F.3d at 1306; see also Silkwood v. 

Kerr-McGee Corp., 464 U.S. 238, 249 (1984) (“[T]he federal government has 

occupied the entire field of nuclear safety concerns, except the limited powers 

expressly ceded to the states.” (quoting Pac. Gas & Elec., 461 U.S. at 212)). The 

PAA was part and parcel of that effort. Roberts, 146 F.3d at 1306. Against the 

backdrop of the congressional decision to take control from the states and create a 

federal “monopoly” in the arena of nuclear energy, id., we do not doubt that 

Congress intended for plaintiffs to bring public liability actions solely under 

federal law. 

The long and short of it is that the Santiagos’ public liability action against 

Pratt & Whitney is not an “action brought under State law.” 42 U.S.C. § 

9658(a)(1). Instead, as the PAA makes plain, the Santiagos have brought their 

claims exclusively under federal law. Thus, they may not avail themselves of 

CERCLA’s discovery-tolling provision. Because their claims are subject instead 

to Florida’s four-year statute of limitations, their claims are time barred.

AFFIRMED.
