In this case, we consider whether an employee must be injured on the outer continental shelf to be eligible for workers’ compensation benefits under the Outer Continental Shelf Lands Act (“OCSLA”), 43 U.S.C. § 1331 et seq. The two other circuits that have considered this question have reached conflicting conclusions.
I.
Decedent Juan Valladolid worked for Pacific Operations Offshore as a roustabout, stationed primarily on one of Pacific Operations’s two offshore drilling platforms. He was killed, however, on the grounds of Pacific Operations’s onshore oil-processing facility when he was crushed by a forklift. His widow seeks workers’ compensation benefits under OCSLA and the Longshore and Harbor Workers’ Compensation Act (“LHWCA”), 33 U.S.C. § 901 et seq.
Pacific Operations runs two offshore oil drilling platforms, the Hogan and the Houchin, both located more than three miles off the coast of California. Valladolid spent roughly 98% of his working time aboard the Hogan. As a roustabout, his work primarily consisted of cleaning and maintenance duties: picking up litter, emptying trash cans, washing decks, painting, fixing equipment, and helping load and unload the platform crane.
Valladolid also spent time working at Pacific Operations’s onshore oil flocculation facility, located on the California coast just 250-300 feet from the shore. 1 This facility, referred to as La Conchita, received crude oil slurry from the Hogan and the Houchin via pipeline. The slurry would then be processed, separating its oil, gas, water, and solid constituents, with the oil and gas routed off site through pipelines to third parties. Valladolid performed maintenance duties at La Conchita, including painting, sandblasting, weed-pulling, cleaning drain-culverts, and operating a forklift.
Crew members traveled to and from the offshore platforms on a crew boat departing from the Casitas Pass Pier, located about three miles from La Conchita. The crew boat was also used to ferry equipment and supplies and to remove scrap metal — pieces of old pipe, storage tanks, catwalks, chain, and cables — from the platforms. The scrap metal was ferried to the Casitas Pass Pier, where it was loaded into trucks and driven to La Conchita. There it was dumped at various spots on the property. Neither the loading crew at the pier nor the truck drivers were employed by Pacific Operations.
One of Valladolid’s duties at La Conchita was to “centralize” the scrap metal from the various locations so that third-party scrap metal vendors could pick the metal up and haul it away. Valladolid would use a forklift to retrieve the scattered metal and transport it to a central location. The consolidation process was performed roughly once every two years. Valladolid was killed during this process when he was crushed by a forklift.
Petitioner, Valladolid’s widow, received death benefits under California’s workers’ compensation scheme. She also filed a claim for benefits under the LHWCA, both directly under the LHWCA and via the OCSLA extension to outer continental shelf workers. After informal proceedings before the local district director of the Department of Labor’s Office of Workers’ Compensation Programs, the matter was referred to an Administrative Law Judge (“ALJ”).
*1130 The ALJ denied Petitioner’s OCSLA claim on the grounds that Valladolid’s injury had occurred outside the geographic situs of the outer continental shelf. The ALJ denied the LHWCA claim on two grounds: (1) Valladolid was not engaged in maritime employment, and (2) he was not injured on a maritime situs. The Benefits Review Board (“BRB”) upheld the ALJ’s denial of the OCSLA benefits under the “situs-of-injury” test, and affirmed the denial of LHWCA benefits on the maritime situs ground. The BRB did not reach the maritime employment issue.
II.
We have jurisdiction to review the final orders of the BRB under 33 U.S.C. § 921(c). We review the BRB’s decisions for errors of law and adherence to the substantial evidence standard.
Pedroza v. BRB,
III.
The LHWCA provides compensation for the disability or death of a maritime employee “if the disability or death results from an injury occurring upon the navigable waters of the United States.” 33 U.S.C. § 903(a). Under the OCSLA workers’ compensation provision, LHWCA benefits are extended to:
[the] disability or death of an employee resulting from any injury occurring as the result of operations conducted on the outer Continental Shelf for the purpose of exploring for, developing, removing, or transporting by pipeline the natural resources, or involving rights to the natural resources, of the subsoil and seabed of the outer Continental Shelf.
43 U.S.C. § 1333(b). The outer continental shelf is comprised of “all submerged lands lying seaward and outside of the area of lands beneath navigable waters”— that is, submerged lands lying outside the territorial jurisdiction of the states. Id. § 1331(a); see id. § 1301(a)(2). State jurisdiction over offshore lands generally extends three miles from the coast line, though in certain cases not relevant here, it may extend further. See id. § 1301(a)(2).
Petitioner contends that the BRB impermissibly applied a “situs-of-injury” requirement for OCSLA workers’ compensation, denying her claim because her husband was killed on shore and not on the outer continental shelf. This is an issue of first impression in the Ninth Circuit. Two other circuits presented with this exact issue have reached conflicting conclusions.
In
Curtis v. Schlumberger Offshore Service, Inc.,
*1131
However, in
Mills v. Director, Office of Workers’ Compensation Programs,
A.
Aside from the two conflicting Court of Appeals decisions, there is little precedent on the question before us. The Supreme Court touched on the question in passing in
Offshore Logistics, Inc. v. Tallentire,
Only one provision of OCSLA superimposes a status requirement on the otherwise determinative OCSLA situs requirement; § 1333(b) makes compensation for the death or injury of an “employee” resulting from certain operations on the Outer Continental Shelf payable under the Longshoremen’s and Harbor Workers’ Compensation Act. We note that because this case does not involve a suit by an injured employee against his employer pursuant to § 1333(b), this provision has no bearing on this case.
Id.
at 219 n. 2,
Pacific Operations contends that this footnote is dispositive of this case. We, on the other hand, agree with the Third Circuit that
Tallentire
is simply not on point.
See Curtis,
Of course, we treat the considered dicta of the Supreme Court with greater weight and deference “as prophecy of what that Court might hold.”
United States v. Montero-Camargo,
For the following reasons, we are convinced that the footnote -in
Tallentire
is of the unconsidered variety not entitled to special deference. The § 1333(b) benefits issue was not before the Court, was not briefed by the parties, and had no relevance to the case before it.
See Tallentire,
Moreover, the import of the Court’s statement to the case at hand is debatable. The Court spoke generally of an OCSLA “situs” requirement, but it is not clear that the Court’s statement requires a “situs-ofinjury,” as opposed to a “situs-of-operations,” test. Section 1333(b) applies only to injuries occurring “as the result of operations conducted on the outer Continental Shelf.” 43 U.S.C. § 1333(b). Clearly, the
operations
must be on the outer continental shelf.
See Herb’s Welding v. Gray (Herb’s Welding II),
The Ninth Circuit cases cited by the parties are similarly unhelpful. In
Kaiser Steel Corp. v. Director, Office of Workers’ Compensation Programs,
[i]n the absence of any other limitation on the face of the statute or in the legislative history of [OCSLA], section 1333(b) should be construed as extending [LHWCA] coverage to all victims of disabling or fatal injuries sustained while working to develop the mineral wealth of the OCS [outer continental shelf].
Id. at 522. This passage does not directly apply to the situs issue, as it came within the context of whether the claimant met *1133 the § 1333(b) “employee” requirement. Id. at 522-23.
In
A-Z International v.
Phillips,
The situs requirement is a predicate for coverage under OCSLA. See 43 U.S.C. § 1333 (1994); see also Offshore Logistics, Inc. v. Tallentire,477 U.S. 207 , 219,106 S.Ct. 2485 ,91 L.Ed.2d 174 (1986) (noting that “Congress determined that the general scope of OCSLA’s coverage ... would be determined principally by locale”).
Id. at 1189 n. 1. We do not find this statement binding or especially persuasive, given that the situs issue was neither argued by the parties nor considered by the Court because the claimant never appealed the decision on the situs question. Id. at 1189. The issue in A-Z International was a procedural question about an ALJ’s contempt power. Id. The comment on the situs issue was gratuitous language appended to the statement of facts and not a considered statement of the law.
B.
Absent clear precedent to guide us on the situs-of-injury issue, we are presented with a straightforward question of statutory construction. “The purpose of statutory construction is to discern the intent of Congress in enacting a particular statute.”
Robinson v. United States,
There are two distinct arguments that OCSLA’s language supports a situs-of-injury requirement. The first argument— the route taken by the Fifth Circuit in
Mills
— is that § 1333(b) itself contains the situs-of-injury requirement.
See
OCSLA was enacted in 1953 to establish federal jurisdiction over the submerged lands beyond the jurisdiction of the states in order to promote the orderly exploitation of minerals lying below the seabed.
See Rodrigue v. Aetna Cas. & Sur. Co.,
Section 1333(b) provides workers’ compensation benefits for “any injury occurring
as the result of
operations conducted on the outer Continental Shelf.”
Id.
§ 1333(b) (emphasis added). The situs-ofoperations requirement is clear; the
operations
must be conducted on the outer continental shelf. However, the only limitation on the
injury
is that it be “the result of’ operations on the outer continental shelf. As many courts have recognized, the phrase “as the result of’ simply denotes causation.
See, e.g., Brown v. Gardner,
The
Mills
court found ambiguity in § 1333(b) by focusing on the word “operations.” According to
Mills,
because the
operations
must occur on the outer continental shelf, the
injury
must also occur on the outer continental shelf: “activity conducted off the OCS, even though related to OCS mineral extraction, does not satisfy § 1333(b).”
Neither are we persuaded that the situs limitations in the other provisions of
*1135
§ 1333 indicate a situs-of-injury requirement for subsection (b). The
Mills
majority felt that these limitations reflected a Congressional intent to limit the reach of the statute to occurrences on the outer continental shelf as part of a “gap-filling” purpose.
Moreover, a comparison of the language of the different provisions strongly implies that subsection (b)’s coverage extends beyond the outer continental shelf. Subsection (c) applies the NLRA to unfair labor practices “occurring upon any artificial island, installation, or other [fixed platform],” id. § 1333(c), while subsection (b) provides coverage for injuries “occurring as the result of operations conducted on the outer Continental Shelf,” id. § 1333(b) (emphasis added). Congress had the ability to craft a situs-of-injury requirement— and did so within the very same section of the statute — yet left it out of subsection (b). See also Longshore & Harbor Workers’ Compensation Act, 33 U.S.C. § 903(a) (limiting coverage to injuries “occurring upon the navigable waters of the United States” (emphasis added)). We should not read one in.
Accordingly, we find that the language of § 1333(b) is unambiguous in not including a situs-of-injury requirement. Indeed, our interpretation of § 1333(b) is confirmed by a Fifth Circuit decision,
Demette v. Falcon Drilling Co., Inc.,
The legislative history does not indicate otherwise. The
Mills
court interpreted § 1333 as a “gap-filler,” solely intended to fill a void in substantive law due to the fact that the outer continental shelf lies beyond
*1136
state jurisdiction.
See Mills,
However, certain legislative history cuts against the gap-filing interpretation of § 1333(b). In particular, a provision allowing benefits only “if recovery for such disability or death through workmen’s compensation proceedings is not provided by State law,” was deleted from the original version of Section 4(c), which became § 1333(b). S.Rep. No. 83-411, at 16 (1953). The Senate committee explained that “[i]t was deemed inadvisable to have the [LHWCA] apply only if there is no applicable State law. By this amendment, all workers on the outer shelf not already protected under laws respecting seamen are protected by the [LHWCA].” Id. at 23. The deletion of this anti-overlap provision gives a clear indication that Congress intended to provide LHWCA coverage regardless of the applicability of state law, seriously undercutting the conception of § 1333(b) as a gap-filler. 5
This makes sense, given that at the time of OCSLA’s enactment the workers’ compensation laws of most relevant states provided coverage for injuries occurring outside state jurisdiction if the employment contract was made within the state.
See, e.g., Ohlhausen v. Sternberg Dredging Co.,
Finally,
Mills
points to an exchange among senators during the committee hearings where the senators concluded that a worker on a platform above state waters would be covered by state workers’ compensation laws even if the drilling slanted into the outer continental shelf.
Outer Continental Shelf: Hearings on S.1901 Before the Comm. on Interior and Insular Affairs,
83d Cong. 15-16 (1953)
*1137
(“OCS Comm. Hearings
”). The
Mills
majority relied on this exchange as evidence of intent that the site of the injury would control coverage.
Second, the exchange came during the discussion of Section 4(a) of the bill, the federal jurisdiction and choice-of-law provision later codified at § 1333(a). Id. at 8-16. The committee was not yet considering the text of Section 4(c), the workers’ compensation provision. See id. at 29. The slant-drilling hypothetical was part of a discussion about the applicability of substantive law in general. See id. at 13-17. Workers’ compensation was simply an example used, along with marriage and domestic laws, to illustrate the bounds of the choice-of-law provision. See id. The usefulness of this exchange in relation to the actual text of Section 4(c) is minimal.
Considered as a whole, the legislative history is inconclusive on the situs issue, other than establishing that § 1333(b) was not intended to simply fill a gap in workers’ compensation law. There is certainly nothing clear enough to persuade us that our reading of the statute is incorrect.
Nor are we persuaded that policy considerations compel the addition of a situsof-injury requirement. Pacific Operations points out the supposed absurdity of workers receiving extra coverage on shore because they “fortuitously” work to further outer continental shelf operations. Pacific Operations also complains about the burden on employers having to purchase coverage under both state and federal schemes.
First, Congress clearly contemplated overlapping coverage with the deletion of the anti-overlap provision in § 1333(b) and has enacted overlapping coverage in other related contexts.
See
33 U.S.C. § 903(a) (applying LHWCA coverage to shoreside activities);
Sun Ship, Inc. v. Pennsylvania,
In any case, it is not necessary to speculate about policy, as the language of § 1333(b) is clear in not containing a situsof-injury requirement. “[I]f Congress’ coverage decisions are mistaken as a matter of policy, it is for Congress to change them. We should not legislate for them.”
Herb’s Welding I,
C.
Pacific Operations presents a different argument, contending that § 1333(a) sets forth a situs requirement that is intended to apply to all of § 1333, including subsection (b). This is a novel argument; it has no support in either Mills, the Fifth Circuit decision, or Curtis, the Third Circuit decision. The only case supporting the proposition is Demette, the Fifth Circuit decision that misstates Mills’ holding.
Section 1333(a)(1) provides that:
The Constitution and laws and civil and political jurisdiction of the United States are extended to the subsoil and seabed of the outer Continental Shelf and to all artificial islands, and all installations and other devices permanently or temporarily attached to the seabed, ... to the same extent as if the outer Continental Shelf were an area of exclusive Federal jurisdiction located within a State.
43 U.S.C. § 1333(a)(1). This subsection simply provides for federal law and jurisdiction over the situs. Nothing in the language purports to limit the applicability of the Constitution, federal laws, or jurisdiction to the outer continental shelf, nor is there anything applying the subsection (a)(1) situs to any other parts of § 1333.
Section 1333(a)(2) does not provide a basis for an overarching situs requirement either. It states that:
the civil and criminal laws of each adjacent State ... are declared to be the law of the United States for that portion of the subsoil and seabed of the outer Continental Shelf, and artificial islands and fixed structures erected thereon, which would be within the area of the State if its boundaries were extended seaward to the outer margin of the outer Continental Shelf.
Id. § 1333(a)(2)(A). Again, nothing purports to limit state law to the subsection (a) situs, nor to apply that situs to the other § 1333 subsections.
This is consistent with the structure of § 1333. Each subsection has its own situs definition, some broader and some narrower than subsection (a)’s. For example, the subsection (c) situs is narrower, applying the NLRA to unfair labor practices “occurring upon any artificial island, installation, or other device referred to in subsection (a),” but not to occurrences on the subsoil or seabed.
Id.
§ 1333(c). The subsection (d) situs is broader, allowing Coast Guard safety regulations for “the artificial islands, installations, and other devices referred to in subsection (a) of this section
or on the waters adjacent thereto.” Id.
§ 1333(d) (emphasis added). As the Supreme Court held in
Tallentire,
§ 1333(a) does not apply to the waters above the outer continental shelf.
Moreover, each subsection expressly incorporates a portion of the subsection (a) situs in their own situs definitions — with the significant exception of subsection (b), the workers’ compensation provision. If subsection (a) applied to all other provisions by its own terms, there would be no need for those provisions to independently incorporate parts of it. And because subsection (a) is referenced in each subsection except subsection (b), the obvious conclusion is that subsection (b) was not intended to be limited by subsection (a).
The legislative history of § 1333 also conclusively demonstrates that subsection (a) was not intended to limit the other provisions. Subsection (b) was originally a *1139 jurisdictional provision, providing federal courts with “original jurisdiction of cases and controversies arising out of or in connection with any operations conducted on the outer Continental Shelf.” Pub.L. No. 83-212, § 4(b), 67 Stat. 462, 463 (1953) (emphasis added). This was clearly meant to encompass more than just occurrences on the subsection (a) situs. 7
The theory that subsection (a) provides a situs requirement applicable to all of § 1333 is simply inconsistent with its plain language, statutory structure, and legislative history. Subsection (a) merely extends federal jurisdiction and federal and state law to the outer continental shelf. It has no applicability beyond that purpose, other than to provide a situs definition that several other provisions expressly incorporate. Because subsection (b) does not incorporate (a), that provision has no bearing on our analysis.
We hold that § 1333(b) may apply to injuries occurring outside the situs of the outer continental shelf, so long as they occur “as the result of operations conducted on the outer continental shelf.”
D.
We do not, however, find that Congress intended to enact a simple “but for” test in covering injuries that occur “as the result of” outer continental shelf operations. Injuries with a tenuous connection to the outer continental shelf are not covered.
Cf. Black Hills Aviation,
Instead, we adopt the following test: the claimant must establish a substantial nexus between the injury and extractive operations on the shelf. To meet the standard, the claimant must show that the work performed directly furthers outer continental shelf operations and is in the regular course of such operations. An injury sustained during employment on the outer continental shelf itself would, by definition, meet this standard. However, an accountant’s workplace injury would not be covered even if related to outer continental shelf operations, while a roustabout’s injury in a helicopter en route to the outer continental shelf likely would be. We leave more precise line-drawing to the specific factual circumstances of later cases.
This is consistent with the
pre-Mills
Fifth Circuit interpretation of § 1333(b), which we endorse. Prior to
Mills,
the Fifth Circuit had long held that § 1333(b) applied to injuries occurring outside the outer continental shelf.
See Nations v. Morris,
In
Mills v. Director, Office of Workers’ Compensation Programs,
Our decision does not extend LHWCA coverage to those whose connection with operations on the Shelf is tenuous. Workers like [the welder in Herb’s Welding II] whose work is only indirectly connected with the Shelf will still not be covered. The “but for” test this Circuit has adopted is not the simple “causa sine qua non ” test of tort law, but includes the requirement that the claimant show a nexus between the work being done and operations on the shelf similar to the proximate cause test in tort law; it requires that the work “furthers] the operation of a fixed rig on the shelf and [is] in the regular course of extractive operations on the shelf”
Id.
at 1015 (quoting
Herb’s Welding II,
In this case, the BRB affirmed the dismissal of Petitioner’s OCSLA claim because Valladolid’s injury did not satisfy the Mills situs-of-injury test. Because we decline to adopt that test, we remand the OCSLA question to the BRB for further consideration consistent with this opinion.
IV.
We next consider whether the BRB erred in denying benefits under the LHWCA. Under 33 U.S.C. § 903(a):
compensation shall be payable under this chapter in respect of disability or death of an employee, but only if the disability or death results from an injury occurring upon the navigable waters of the United States (including any adjoining pier, wharf, dry dock, terminal, building way, marine railway, or other adjoining area customarily used by an employer in loading, unloading, repairing, dismantling, or building a vessel).
A LHWCA “employee” is “any person engaged in maritime employment.”
Id.
§ 902(3). Thus, a claimant seeking workers’ compensation under the LHWCA must establish both a maritime situs and a maritime status.
Herb’s Welding I,
Petitioner contends that the BRB erred in affirming the ALJ’s determination that the onshore La Conchita facility, where Valladolid was killed, was not a maritime situs. Petitioner does not contest the ALJ’s factual findings regarding the facility, but argues that the BRB should have reversed the ALJ on the legal question of whether La Conchita qualifies as an “adjoining area customarily used by an employer in loading [or] unloading ... a vessel.” Id. § 903(a). We reject Petitioner’s position and affirm the BRB.
We use a “functional relationship” test in determining whether a particular facility is a § 903(a) “adjoining area.”
Brady-Hamilton Stevedore Co. v. Herron,
*1141
the particular suitability of the site for the maritime uses referred to in the statute; whether adjoining properties are devoted primarily to uses in maritime commerce; the proximity of the site to the waterway; and whether the site is as close to the waterway as is feasible given all of the circumstances in the case.
Id. Although physical congruity with navigable water is not required, the facility must be “used as an integral part of long-shoring operations.” Id.
Applying the
Herron
factors, we agree with the BRB that La Conchita is not a maritime situs. Although the facility is only 250-300 feet from the ocean, it is separated from the water by a highway and railroad tracks and has no direct access to any pier, dock, or other loading facility.
See Motoviloff v. Dir., Office of Workers’ Comp. Programs,
Petitioner argues that La Conchita should be considered a “transshipment” facility because scrap metal from the offshore platforms was dumped there before being sold to third parties. Petitioner analogizes to
P.C. Pfeiffer Co. v. Ford,
We find the analogy unpersuasive. First of all, Pfeiffer never addressed the situs requirement because the injuries occurred on a dock and a pier, which are indisputably maritime situs. Second, the handling of scrap metal at La Conchita did not involve “moving cargo directly from ship to land transportation.” Id. The scrap metal was unloaded at the pier by third-party longshoremen, loaded into trucks driven by third-party drivers, and driven three miles to La Conchita, where it was dumped and would wait for up to two years before being hauled away by third-party dealers. The maritime activities— the movement of cargo “directly from ship to land transportation” — began and ended at the Casitas Pass Pier. Finally, La Conchita is simply not an “adjoining area” within the meaning of § 903(a). It is three miles from the pier and not adjacent to any maritime facilities.
The record demonstrates that the primary purpose of the facility — and the only reason for its proximity to the coastline— is to receive and process crude oil slurry extracted by the offshore platforms, a non-maritime activity.
Herb’s Welding I,
Accordingly, we affirm the BRB’s denial of benefits under the LHWCA. Because Valladolid’s injury does not satisfy the situs requirement, and because the BRB did not reach the status issue, we do not address whether Valladolid was a maritime employee.
Williams v. Dir., Office of Workers’ Comp. Programs,
V.
We hold that the OCSLA workers’ compensation provision, 43 U.S.C. *1142 § 1333(b), applies to any injury resulting from operations on the outer continental shelf, regardless of the location of the injury. An injury is “the result of’ outer continental shelf operations if there is a substantial nexus between the injury and the operations. We therefore reject the situs-of-injury test adopted by the BRB, and remand for further considerations consistent with this opinion.
We also hold that the BRB did not err in finding that La Conchita was not a maritime situs. Accordingly, we affirm the denial of workers’ compensation benefits under the LHWCA.
Each side shall bear its owns costs.
GRANTED in part, DENIED in part, and REMANDED.
Notes
. Pacific contends that the facility is actually 250-300 yards from the ocean. Because our decision does not turn on the difference between 250-300 feet and 250-300 yards, we assume for the purposes of this appeal that Petitioner’s measure is correct.
. The
Mills
court also found support for its situs-of-injury test in
Herb’s Welding, Inc. v. Gray (.Herb’s Welding I),
. Our position finds support in
Murakami,
a Federal Circuit decision interpreting similar language in a reparations statute.
Murakami
involved a claim under the Civil Liberties Act of 1988, which provided a redress payment for individuals who were "deprived of liberty or property
as a result of”
the internment of Japanese-Americans during World War II.
. In fact, Demette's interpretation of
Mills
would put that decision in direct conflict with the Supreme Court's decision in
Tallentire.
In an effort to avoid overruling its own precedent applying OCSLA to helicopter crashes on the waters above the outer continental shelf,
Mills
defined § 1333(b) as applying to “injury or death on an OCS platform or the waters above the OCS.”
.
Mills
attempts to explain away the deletion, arguing that it "indicates that, at most, Congress was prepared to tolerate overlapping federal and state workers’ compensation coverage on the OCS itself. But the proviso's deletion does not justify overlapping coverage for employees whose feet are planted firmly on state soil."
Mills,
. In any case, the senators only concluded that state law applied on state soil and never considered whether LHWCA benefits might also apply.
