Pauley v. Bethenergy Mines Inc./Opinion of the Court
The black lung benefits program, created by Congress, was to be administered first by the Social Security Administration (SSA) under the auspices of the then-existent Department of Health, Education, and Welfare (HEW), and later by the Department of Labor (DOL). Congress authorized these Departments, during their respective tenures, to adopt interim regulations governing the adjudication of claims for black lung benefits, but constrained the Secretary of Labor by providing that the DOL regulations "shall not be more restrictive than" HEW's. This litigation calls upon us to determine whether the Secretary of Labor has complied with that constraint.
* A.
The black lung benefits program was enacted originally as Title IV of the Federal Coal Mine Health and Safety Act of 1969 (FCMHSA), 83 Stat. 792, 30 U.S.C. § 901 et seq., to provide benefits for miners totally disabled due at least in part to pneumoconiosis arising out of coal mine employment, and to the dependents and survivors of such miners. See Pittston Coal Group v. Sebben, 488 U.S. 105, 108, 109 S.Ct. 414, 417, 102 L.Ed.2d 408 (1988); Mullins Coal Co. v. Director, OWCP, 484 U.S. 135, 138, 108 S.Ct. 427, 429, 98 L.Ed.2d 450 (1987).
Through FCMHSA, Congress established a bifurcated system of compensating miners disabled by pneumoconiosis. [1] Part B thereof created a temporary program administered by the Social Security Administration under the auspices of the Secretary of Health, Education, and Welfare. This program was intended for the processing of claims filed on or before December 31, 1972. Benefits awarded under part B were paid by the Federal Government. For claims filed after 1972, part C originally authorized a permanent program, administered by the Secretary of Labor, to be coordinated with federally approved state workmen's compensation programs. Benefits awarded under part C were to be paid by the claimants' coal mining employers.
Under FCMHSA, the Secretary of HEW was authorized to promulgate permanent regulations regarding the determination and adjudication of part B claims. 30 U.S.C. § 921(b). The Secretary's discretion was limited, however, by three statutory presumptions defining eligibility under the part B program. § 921(c). For a claimant suffering from pneumoconiosis who could establish 10 years of coal mine employment, there "shall be a rebuttable presumption that his pneumoconiosis arose out of such employment." § 921(c)(1). Similarly, for a miner with at least 10 years of coal mine employment who "died from a respirable disease there shall be a rebuttable presumption that his death was due to pneumoconiosis." § 921(c)(2). Finally, there was an irrebuttable presumption that a miner presenting medical evidence demonstrating complicated pneumoconiosis was totally disabled as a result of that condition. § 921(c)(3). Consistent with these presumptions, HEW promulgated permanent regulations prescribing the methods and standards for establishing entitlement to black lung benefits under part B. See 20 CFR §§ 410.401 to 410.476 (1990).
Dissatisfied with the increasing backlog of unadjudicated claims and the relatively high rate of claim denials resulting from the application of the HEW permanent regulations, Congress in 1972 amended FCMSHA and redesignated Title IV of that Act as the Black Lung Benefits Act of 1972. 86 Stat. 150. See S.Rep. No. 92-743 (1972), U.S.Code Cong. & Admin.News 1972, p. 2305. See also Comptroller General of the United States, General Accounting Office, Report to the Congress: Achievements, Administrative Problems, and Costs in Paying Black Lung Benefits to Coal Miners and Their Widows 16-18 (September 5, 1972) (nationally, as of December 31, 1971, claims filed were 347,716, claims processed were 322,582, and rate of claim denial was 50.5 percent). In addition to extending the coverage of part B to those claims filed by living miners prior to July 1, 1973, and those filed by survivors before January 1, 1974, the 1972 amendments liberalized in several ways the criteria and procedures applicable to part B claims. First, the amendments added a fourth statutory presumption of total disability due to pneumoconiosis for claimants unable to produce X-ray evidence of the disease. This presumption applied to a claimant with 15 years of coal mine employment who presented evidence of a totally disabling respiratory or pulmonary impairment. Congress expressly limited rebuttal of the presumption to a showing that the miner did not have pneumoconiosis or that his respiratory or pulmonary impairment did not arise out of employment in a coal mine. 30 U.S.C. § 921(c)(4). Second, the 1972 amendments redefined "total disability" to permit an award of benefits on a showing that a miner was unable to perform his coal mining duties or other comparable work-as opposed to the prior requirement that the miner demonstrate that he was unable to perform any job, see § 902(f) and prohibited HEW from denying a claim for benefits solely on the basis of a negative X ray. § 923(b). Third, the 1972 amendments made it easier for survivors of a deceased miner who had been disabled due to pneumoconiosis but had died from a cause unrelated to the disease to demonstrate eligibility for benefits. See § 901. Finally, the amendments made clear that "[i]n determining the validity of claims under [part B], all relevant evidence shall be considered." § 923(b).
In response to these amendments, the Secretary of HEW adopted interim regulations "designed to 'permit prompt and vigorous processing of the large backlog of claims' that had developed during the early phases of administering part B." Sebben, 488 U.S., at 109, 109 S.Ct., at 417, quoting 20 CFR § 410.490(a) (1973). [2] These interim regulations established adjudicatory rules for processing part B claims that permit the invocation of a presumption of eligibility upon demonstration by the claimant of specified factors, and a subsequent opportunity for the Social Security Administration, in administering the program, to rebut the presumption.
Specifically, the HEW interim regulations permit claimants to invoke a rebuttable presumption that a miner is "totally disabled due to pneumoconiosis" in one of two ways. First, the claimant can introduce an X ray, a biopsy, or an autopsy indicating pneumoconiosis. 20 CFR § 410.490(b)(1)(i) (1990). Second, for a miner with at least 15 years of coal mine employment, a claimant may introduce ventilatory studies establishing the presence of a chronic respiratory or pulmonary disease. § 410.490(b)(1)(ii). In either case, in order to invoke the presumption, the claimant also must demonstrate that the "impairment established in accordance with paragraph (b)(1) of this section arose out of coal mine employment (see §§ 410.416 and 410.456)." § 410.490(b)(2).
Once a claimant invokes the presumption of eligibility under § 410.490(b), the HEW interim regulations permit rebuttal by the SSA upon a showing that the miner is doing his usual coal mine work or comparable and gainful work, or is capable of doing such work. See § 410.490(c).
The statutory changes adopted by the 1972 amendments and the application of HEW's interim regulations resulted in a surge of claims approvals under part B. See Lopatto, The Federal Black Lung Program: A 1983 Primer, 85 W.Va.L.Rev. 677, 686 (1983) (demonstrating that the overall approval rate for part B claims had substantially increased by December 31, 1974). Because the HEW interim regulations expired with the part B program, however, the Secretary of Labor was constrained to adjudicate all part C claims, i.e., those filed after June 30, 1973, by living miners, and after December 31, 1973, by survivors, under the more stringent permanent HEW regulations. See Sebben, 488 U.S., at 110, 109 S.Ct., at 418. Neither the Congress nor the Secretary of Labor was content with the application to part C claims of the unwieldy and restrictive permanent regulations. See Letter, dated Sept. 13, 1974, of William J. Kilberg, Solicitor of Labor, to John B. Rhinelander, General Counsel, Department of HEW, appearing in H.R.Rep. No. 94-770, p. 14 (1975). Not only did the application of the permanent regulations cause the DOL to process claims slowly, but the DOL's claims approval rate was significantly below that of the SSA. See Lopatto, supra, at 691. Accordingly, Congress turned its attention once again to the black lung benefits program.
The Black Lung Benefits Reform Act of 1977 (BLBRA), 92 Stat. 95, approved and effective Mar. 1, 1978, further liberalized the criteria for eligibility for black lung benefits in several ways. First, the Act expanded the definition of pneumoconiosis to include "sequelae" of the disease, including respiratory and pulmonary impairments arising out of coal mine employment. See 30 U.S.C. § 902(b). Second, BLBRA required the DOL to accept a board-certified or board-eligible radiologist's interpretation of submitted X rays if the films met minimal quality standards, thereby prohibiting the DOL from denying a claim based on a secondary assessment of the X rays provided by a Government-funded radiologist. See § 923(b). Finally, the BLBRA added a fifth presumption of eligibility and otherwise altered the entitlement structure to make it easier for survivors of a deceased long-term miner to obtain benefits. See §§ 921(c)(5) and 902(f).
In addition to liberalizing the statutory prerequisites to benefit entitlement, the BLBRA authorized the DOL to adopt its own interim regulations for processing part C claims filed before March 31, 1980. In so doing, Congress required that the "[c]riteria applied by the Secretary of Labor . . . shall not be more restrictive than the criteria applicable to a claim filed on June 30, 1973." § 902(f)(2).
The Secretary of Labor, pursuant to this authorization, adopted interim regulations governing the adjudication of part C claims. These regulations differ significantly from the HEW interim regulations. See 20 CFR § 727.203 (1990). The DOL regulations include two presumption provisions similar to the two presumption provisions in the HEW interim regulations. Compare §§ 727.203(a)(1) and (2) with §§ 410.490(b)(1)(i) and (ii). To invoke the presumption of eligibility under these two provisions, however, a claimant need not prove that the "impairment . . . arose out of coal mine employment," as was required under the HEW interim regulations. See § 410.490(b)(2).
In addition, the DOL interim regulations add three methods of invoking the presumption of eligibility not included in the HEW interim regulations. Specifically, under the DOL regulations, a claimant can invoke the presumption of total disability due to pneumoconiosis by submitting blood gas studies that demonstrate the presence of an impairment in the transfer of oxygen from the lung alveoli to the blood; by submitting other medical evidence establishing the presence of a totally disabling respiratory or pulmonary impairment; or, in the case of a deceased miner for whom no medical evidence is available, by submitting a survivor's affidavit demonstrating such a disability. See §§ 727.203(a)(3), (4), and (5).
Finally, the DOL interim regulations provide four methods for rebutting the presumptions established under § 727.203. Two of the rebuttal provisions mimic those in the HEW regulations, permitting rebuttal upon a showing that the miner is performing or is able to perform his coal mining or comparable work. See §§ 727.203(b)(1) and (2). The other two rebuttal provisions are at issue in these cases. Under these provisions, a presumption of total disability due to pneumoconiosis can be rebutted if "[t]he evidence establishes that the total disability or death of the miner did not arise in whole or in part out of coal mine employment," or if "[t]he evidence establishes that the miner does not, or did not, have pneumoconiosis." See §§ 727.203(b)(3) and (4).
The three cases before us present the question whether the DOL's interim regulations are "more restrictive than" the HEW's interim regulations by virtue of the third and fourth rebuttal provisions, and therefore are inconsistent with the agency's statutory authority. In No. 89-1714, Pauley v. BethEnergy Mines, Inc., the Court of Appeals for the Third Circuit concluded that the DOL interim regulations were not more restrictive. BethEnergy Mines, Inc. v. Director, OWCP, 890 F.2d 1295 (1989). John Pauley, the now-deceased husband of petitioner Harriet Pauley, filed a claim for black lung benefits on April 21, 1978, after he had worked 30 years in the underground mines of Pennsylvania. Pauley stopped working soon after he filed his claim for benefits. At a formal hearing on November 5, 1987, the Administrative Law Judge (ALJ) found that Pauley had begun to experience shortness of breath, coughing, and fatigue in 1974, and that those symptoms had gradually worsened, causing him to leave his job in the mines. The ALJ also found that Pauley had arthritis requiring several medications daily, had suffered a stroke in January 1987, and had smoked cigarettes for 34 years until he stopped in 1974.
Because respondent BethEnergy did not contest the presence of coal workers' pneumoconiosis, the ALJ found that the presumption had been invoked under § 727.203(a)(1). Turning to the rebuttal evidence, the judge concluded that Pauley was not engaged in his usual coal mine work or comparable and gainful work, and that Pauley was totally disabled from returning to coal mining or comparable employment. See §§ 727.203(b)(1) and (2). The judge then weighed the evidence submitted under § 727.203(b)(3), and determined that respondent BethEnergy had sustained its burden of establishing that pneumoconiosis was not a contributing factor in Pauley's total disability and, accordingly, that his disability did not "arise in whole or in part out of coal mine employment." § 727.203(b)(3). See Carozza v. United States Steel Corp., 727 F.2d 74 (CA3 1984).
Having determined that Pauley was not entitled to receive black lung benefits under the DOL interim regulations, the ALJ felt constrained by Third Circuit precedent to apply the HEW interim regulations to Pauley's claim. He first concluded that respondent BethEnergy's concession that Pauley had pneumoconiosis arising out of coal mining employment was sufficient to invoke the presumption of total disability due to pneumoconiosis under § 410.490(b). Because the evidence demonstrated Pauley's inability to work, and the ALJ interpreted § 410.490(c) as precluding rebuttal of the presumption by "showing that the claimant's total disability is unrelated to his coal mine employment," the judge found that BethEnergy could not carry its burden on rebuttal, and that Pauley was entitled to benefits.
After the ALJ denied its motion for reconsideration, BethEnergy appealed unsuccessfully to the Benefits Review Board. It then sought review in the Court of Appeals for the Third Circuit. That court reversed. It pointed out that the decisions of the ALJ and the Benefits Review Board created "two disturbing circumstances." 890 F.2d, at 1299. First, the court found it "surely extraordinary," ibid., that a determination that Pauley was totally disabled from causes unrelated to pneumoconiosis, which was sufficient to rebut the presumption under § 727.203(b)(3), would preclude respondent BethEnergy from rebutting the presumption under § 410.490(c). Second, the court considered it to be "outcome determinative" that the purpose of the Benefits Act is to provide benefits to miners totally disabled at least in part due to pneumoconiosis if the disability arises out of coal mine employment, and that the ALJ had made unchallenged findings that Pauley's disability did not arise even in part out of such employment. 890 F.2d, at 1299-1300. The court found it to be "perfectly evident that no set of regulations under [the Benefits Act] may provide that a claimant who is statutorily barred from recovery may nevertheless recover." Id., at 1300.
Asserting that this Court's decision in Sebben, supra, was not controlling because that decision concerned only the invocation of the presumption and not its rebuttal, the court then concluded that Congress' mandate that the criteria used by the Secretary of Labor be not more restrictive than the criteria applicable to a claim filed on June 30, 1973, applied only to the criteria for determining whether a claimant is "totally disabled," not to the criteria used in rebuttal. Finally, the court pointed out that its result would not differ if it applied the rebuttal provisions of § 410.490(c) to Pauley's claim, because subsections (c)(1) and (2) make reference to § 410.412(a), which refers to a miner's being "totally disabled due to pneumoconiosis." According to the Third Circuit, there would be no reason for the regulations to include such a reference "unless it was the intention of the Secretary to permit rebuttal by a showing that the claimant's disability did not arise at least in part from coal mine employment." 890 F.2d, at 1302.
In the two other cases now before us, No. 90-113, Clinchfield Coal Co. v. Director, OWCP, and No. 90-114, Consolidation Coal Co. v. Director, OWCP, the Court of Appeals for the Fourth Circuit struck down the DOL interim regulations. John Taylor, a respondent in No. 90-113, applied for black lung benefits in 1976, after having worked for almost 12 years as a coal loader and roof bolter in underground coal mines. The ALJ found that Taylor properly had invoked the presumption of eligibility for benefits under § 727.203(a)(3), based on qualifying arterial blood gas studies demonstrating an impairment in the transfer of oxygen from his lungs to his blood. The ALJ then proceeded to weigh the rebuttal evidence, consisting of negative X-ray evidence, nonqualifying ventilatory study scores, and several medical reports respectively submitted by Taylor and by his employer, petitioner Clinchfield Coal Company. In light of this evidence, the ALJ concluded that Taylor neither suffered from pneumoconiosis nor was totally disabled. Rather, the evidence demonstrated that Taylor suffered from chronic bronchitis caused by 30 years of cigarette smoking and obesity. The Benefits Review Board affirmed, concluding that the ALJ's decision was supported by substantial evidence.
The Court of Appeals reversed. Taylor v. Clinchfield Coal Co., 895 F.2d 178 (1990). The court first dismissed the argument that the DOL interim regulations cannot be considered more restrictive than HEW's as applied to Taylor because Taylor invoked the presumption of eligibility based on arterial blood gas studies, a method of invocation available under the DOL regulations but not under HEW's, and was therefore unable to use the rebuttal provisions of the HEW interim regulations as a benchmark. Id., at 182. The court reasoned that it was a "matter of indifference" how the claimant invoked the presumption of eligibility, and rejected the argument that the rebuttal provisions must be evaluated in light of corresponding invocation provisions. "It is the fact of establishment of the presumption and the substance thereof which is of consequence in this case, not the number of the regulation which provides for such establishment." Ibid.
Focusing on the DOL's rebuttal provisions in isolation, the Fourth Circuit determined that the third and fourth rebuttal methods "permit rebuttal of more elements of entitlement to benefits than do the interim HEW regulations," because the HEW regulations permit rebuttal "solely through attacks on the element of total disability," while the DOL regulations "allow the consideration of evidence disputing both the presence of pneumoconiosis and the connection between total disability and coal mine employment." Ibid. Accordingly, the court concluded that the DOL interim regulations were more restrictive than those found in § 410.490, and that the application of these regulations violated 30 U.S.C. § 902(f). [3]
One judge dissented. Noting that the panel's decision was in conflict with the Sixth Circuit in Youghiogheny and Ohio Coal Co. v. Milliken, 866 F.2d 195 (1989), and with the Third Circuit in Pauley, he concluded that those decisions "do less violence to congressional intent, and avoid . . . upsetting the statutory scheme." 895 F.2d, at 184.
Albert Dayton, a respondent in No. 90-114, applied for black lung benefits in 1979, after having worked as a coal miner for 17 years. The ALJ found that Dayton had invoked the presumption of eligibility based on ventilatory test scores showing a chronic pulmonary condition. The judge then determined that petitioner Consolidation Coal Company had successfully rebutted the presumption under §§ 727.203(b)(2) and (4) by demonstrating that Dayton did not have pneumoconiosis and, in any event, that Dayton's pulmonary impairment was not totally disabling. The Benefits Review Board affirmed, concluding that the medical evidence demonstrated that Dayton's pulmonary condition was unrelated to coal dust exposure, but was instead secondary to his smoking and "other ailments," and that the ALJ had correctly concluded that Consolidation had rebutted the presumption under § 727.203(b)(4). [4]
The Fourth Circuit reversed. Dayton v. Consolidation Coal Co., 895 F.2d 173 (1990). Relying on its decision in Taylor, the court held that 30 U.S.C. § 902(f) required Dayton's claim to be adjudicated "under the less restrictive rebuttal standards of § 410.490." 895 F.2d, at 175. Concluding that the HEW regulations did not permit rebuttal upon a showing that the claimant does not have pneumoconiosis, the court stated that the ALJ's finding that Dayton does not have pneumoconiosis "is superfluous and has no bearing on the case." Id., at 176, n. *.
In view of the conflict among the Courts of Appeals, we granted certiorari in the three cases and consolidated them for hearing in order to resolve the issue of statutory construction. --- U.S. ----, 111 S.Ct. 340, 112 L.Ed.2d 304 (1990). [5]
We turn to the statutory text that provides that "[c]riteria applied by the Secretary of Labor . . . shall not be more restrictive than the criteria applicable" under the interim HEW regulations. 30 U.S.C. § 902(f)(2). See Sebben, 488 U.S., at 113, 109 S.Ct., at 419. Specifically, we must determine whether the third and fourth rebuttal provisions in the DOL regulations render the DOL regulations more restrictive than were the HEW regulations. These provisions permit rebuttal of the presumption of eligibility upon a showing that the miner's disability did not arise in whole or in part out of coal mine employment or that the miner does not have pneumoconiosis. [6]
* In the BLBRA, Congress specifically constrained the Secretary of Labor's discretion through the directive that the criteria applied to part C claims could "not be more restrictive than" that applied to part B claims. 30 U.S.C. § 902(f)(2). The claimants and the dissent urge that this restriction is unambiguous, and that no deference is due the Secretary's determination that her interim regulations are not more restrictive than the HEW's. In the alternative, both the claimants and the dissent argue that regardless of whether the statutory mandate is clear, the only interpretation of the HEW interim regulations that warrants deference is the interpretation given those regulations by the Secretary of HEW. In our view, this position misunderstands the principles underlying judicial deference to agency interpretations, as well as the scope of authority delegated to the Secretary of Labor in the BLBRA.
Judicial deference to an agency's interpretation of ambiguous provisions of the statutes it is authorized to implement reflects a sensitivity to the proper roles of the political and judicial branches. See Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 866, 104 S.Ct. 2778, 2793, 81 L.Ed.2d 694 (1984) ("[F]ederal judges-who have no constituency-have a duty to respect legitimate policy choices made by those who do"); see also Silberman, Chevron-The Intersection of Law & Policy, 58 Geo.Wash.L.Rev. 821, 822-24 (1990). As Chevron itself illustrates, the resolution of ambiguity in a statutory text is often more a question of policy than of law. See Sunstein, Law and Administration After Chevron, 90 Colum.L.Rev. 2071, 2085-2088 (1990). When Congress, through express delegation or the introduction of an interpretive gap in the statutory structure, has delegated policy-making authority to an administrative agency, the extent of judicial review of the agency's policy determinations is limited. Cf. Adams Fruit Co. v. Barrett, --- U.S. ----, ----, 110 S.Ct. 1384, 1390, 108 L.Ed.2d 585 (1990) ("A precondition to deference under Chevron is a congressional delegation of administrative authority"); Chevron, 467 U.S., at 864-866, 104 S.Ct., at 2792-2793.
It is precisely this recognition that informs our determination that deference to the Secretary is appropriate here. The Black Lung Benefits Act has produced a complex and highly technical regulatory program. The identification and classification of medical eligibility criteria necessarily require significant expertise, and entail the exercise of judgment grounded in policy concerns. In those circumstances, courts appropriately defer to the agency entrusted by Congress to make such policy determinations. See Martin v. OSHRC, --- U.S. ----, ----, 111 S.Ct. 1171, 1177, 113 L.Ed.2d 117 (1991); Aluminum Co. of America v. Central Lincoln Peoples' Utility District, 467 U.S. 380, 390, 104 S.Ct. 2472, 2479, 81 L.Ed.2d 301 (1984).
In Sebben, we declined to defer to the Secretary's interpretation of the term "criteria" as used in § 902(f)(2), as including only medical but not evidentiary criteria, because we found Congress' intent to include all criteria in that provision to be manifest. See Sebben, 488 U.S., at 113-114, 116, 109 S.Ct., at 419-420, 421. With respect to the phrase "not . . . more restrictive than," Congress' intent is similarly clear: the phrase cannot be read except as a delegation of interpretive authority to the Secretary of Labor.
That Congress intended in the BLBRA to delegate to the Secretary of Labor broad policy-making discretion in the promulgation of his interim regulations is clear from the text of the statute and the history of this provision. Congress declined to require that the DOL adopt the HEW interim regulations verbatim. Rather, the delegation of authority requires only that the DOL's regulations be "not . . . more restrictive than" HEW's. Further, the delegation was made with the intention that the program evolve as technological expertise matured. The Senate Committee on Human Resources stated:
"It is the Committee's belief that the Secretary of Labor should have sufficient statutory authority . . . to establish eligibility criteria. . . . It is intended that pursuant to this authority the Secretary of Labor will make every effort to incorporate within his regulations . . . to the extent feasible the advances made by medical science in the diagnosis and treatment of pneumoconiosis . . . since the promulgation in 1972 of the Secretary of HEW's medical eligibility criteria." S.Rep. No. 95-209, p. 13 (1977).
In addition, the Conference Report indicated that the DOL's task was more than simply ministerial when it informed the Secretary that "such [new] regulations shall not provide more restrictive criteria than [the HEW interim regulations], except that in determining claims under such criteria all relevant medical evidence shall be considered." H.R.Conf.Rep. No. 95-864, p. 16 (1977), U.S.Code Cong. & Admin.News 1977, pp. 237, 309 (emphasis added). As delegated by Congress, then, the Secretary's authority to promulgate interim regulations "not . . . more restrictive than" the HEW interim regulations necessarily entails the authority to interpret HEW's regulations and the discretion to promulgate interim regulations based on a reasonable interpretation thereof. From this congressional delegation derives the Secretary's entitlement to judicial deference.
The claimants also argue that even if the Secretary of Labor's interpretation of the HEW interim regulations is generally entitled to deference, such deference would not be appropriate in this instance because that interpretation has changed without explanation throughout the litigation of these cases. We are not persuaded. As a general matter, of course, the case for judicial deference is less compelling with respect to agency positions that are inconsistent with previously held views. See Bowen v. Georgetown University Hospital, 488 U.S. 204, 212-213, 109 S.Ct. 468, 473-474, 102 L.Ed.2d 493 (1988). However, the Secretary has held unswervingly to the view that the DOL interim regulations are consistent with the statutory mandate and not more restrictive than the HEW interim regulations. This view obviously informed the structure of the DOL's regulations. In response to comments suggesting that the DOL's proposed interim regulations might violate § 902(f)(2) because they required that all relevant evidence be considered in determining eligibility, the Secretary replied that "the Social Security regulations, while less explicit, similarly do not limit the evidence which can be considered in rebutting the interim presumption." See 43 Fed.Reg. 36,826 (1978). Moreover, this position has been faithfully advanced by each Secretary since the regulations were promulgated. See e.g., Sebben, 488 U.S., at 119, 109 S.Ct., at 423. Accordingly, the Secretary's defense of her interim regulations warrants deference from this Court.
Having determined that the Secretary's position is entitled to deference, we must decide whether this position is reasonable. See Chevron, 467 U.S., at 845, 104 S.Ct., at 2783. The claimants and the dissent argue that this issue can be resolved simply by comparing the two interim regulations. This argument is straightforward; it reasons that the mere existence of regulatory provisions permitting rebuttal of statutory elements not rebuttable under the HEW interim regulations renders the DOL interim regulations more restrictive than HEW's and, as a consequence renders the Secretary's interpretation unreasonable. See Tr. of Oral Arg. 22-24. Specifically, the claimants and the dissent assert that the HEW interim regulations plainly contain no provision, either in the invocation subsection or in the rebuttal subsection, that directs factual inquiry into the issue of disability causation or the existence of pneumoconiosis. Accordingly, under the claimants' reading of the regulations, there is no manner in which the DOL interim regulations can be seen to be "not . . . more restrictive than" the HEW regulations.
The regulatory scheme, however, is not so straightforward as the claimants would make it out to be. We have noted before the Byzantine character of these regulations. See Sebben, 488 U.S., at 109, 109 S.Ct., at 418 (the second presumption is "drafted in a most confusing manner"); id., at 129, 109 S.Ct., at 428 (dissenting opinion) (assuming that the drafters "promulgated a scrivener's error"). In our view, the Secretary presents the more reasoned interpretation of this complex regulatory structure, an interpretation that has the additional benefit of providing coherence among the statute and the two interim regulations.
The premise underlying the Secretary's interpretation of the HEW interim regulations is that the regulations were adopted to ensure that miners who were disabled due to pneumoconiosis arising out of coal mine employment would receive benefits from the black lung program. Under the Secretary's view, it disserves congressional intent to interpret HEW's interim regulations to allow recovery by miners who do not have pneumoconiosis or whose total disability did not arise, at least in part, from their coal mine employment. We agree. See Usery v. Turner Elkhorn Mining Co., 428 U.S. 1, 22, n. 21, 96 S.Ct. 2882, 2896, n. 21, 49 L.Ed.2d 752 (1976) ("[A]n operator can be liable only for pneumoconiosis arising out of employment in a coal mine"); Mullins Coal Co. v. Director, OWCP, 484 U.S. 135, 158, 108 S.Ct. 427, 439, 98 L.Ed.2d 450 (1987) ("[I]f a miner is not actually suffering from the type of ailment with which Congress was concerned, there is no justification for presuming that the miner is entitled to benefits").
The Secretary and the nonfederal petitioners contend that SSA adjudications under the HEW interim regulations permitted the factual inquiry specified in the third and fourth rebuttal provisions of the DOL regulations. According to the Secretary, subsection (b)(2) of HEW's invocation provisions, and the provisions incorporated by reference into that subsection, do the work of DOL's third and fourth rebuttal methods. Subsection (b)(2) of the HEW interim regulations provides that in order to invoke a presumption of eligibility the claimant must demonstrate that the "impairment established in accordance with paragraph (b)(1) of this section arose out of coal mine employment (see §§ 410.416 and 410.456)." 20 CFR § 410.490(b)(2) (1990). Section 410.416(a) provides:
the Nation's coal mines, and is suffering or suffered from pneumoconiosis, it will be presumed, in the absence of persuasive evidence to the contrary, that the pneumoconiosis arose out of such employment."
See also § 410.456.
The Secretary interprets the requirement in § 410.490(b)(2) that the claimant demonstrate that the miner's impairment "arose out of coal mine employment" as comparable to the DOL's third rebuttal provision, which permits the mine operator to show that the miner's disability "did not arise in whole or in part out of coal mine employment." § 727.203(b)(3). With respect to DOL's fourth rebuttal provision, the Secretary emphasizes that the statute defines pneumoconiosis as "a chronic dust disease . . . arising out of coal mine employment." See 30 U.S.C. § 902(b). Accordingly, she views the reference to §§ 410.416 and 410.456 in HEW's invocation provision, and the acknowledgment within these sections that causation is to be presumed "in the absence of persuasive evidence to the contrary," as demonstrating that a miner who is shown not to suffer from pneumoconiosis could not invoke HEW's presumption. [7]
Petitioners Clinchfield and Consolidation adopt the Third Circuit's reasoning in Pauley. The court in Pauley relied on the reference in the HEW rebuttal provisions to § 410.412(a)(1), which in turn refers to a miner's being "totally disabled due to pneumoconiosis." The Third Circuit reasoned that this reference must indicate "the intention of the Secretary [of HEW] to permit rebuttal by a showing that the claimant's disability did not arise at least in part from coal mine employment." 890 F.2d, at 1302.
The claimants respond that the Secretary has not adopted the most natural reading of subsection (b)(2). Specifically, the claimants argue that miners who have 10 years of coal mine experience and satisfy the requirements of subsection (b)(1) automatically obtain the presumption of causation that § 410.416 or § 410.456 confers, and thereby satisfy the causation requirement inherent in the Act. In addition, the claimants point out that the reference in the HEW rebuttal provisions to § 410.412(a)(1) may best be read as a reference only to the definition of the term "comparable and gainful work," not to the disability causation provision of § 410.412(a). While it is possible that the claimants' parsing of these impenetrable regulations would be consistent with accepted canons of construction, it is axiomatic that the Secretary's interpretation need not be the best or most natural one by grammatical or other standards. EEOC v. Commercial Office Products Co., 486 U.S. 107, 115, 108 S.Ct. 1666, 1671, 100 L.Ed.2d 96 (1988). Rather, the Secretary's view need be only reasonable to warrant deference. Ibid.; Mullins, 484 U.S., at 159, 108 S.Ct., at 440.
The claimants' assertion that the Secretary's interpretation is contrary to the plain language of the statute ultimately rests on their contention that subsections (b)(1)(i) and (ii) of the HEW interim regulations create a "conclusive" presumption of entitlement without regard to the existence of competent evidence demonstrating that the miner does not or did not have pneumoconiosis or that the miner's disability was not caused by coal mine employment. This argument is deficient in two respects. First, the claimants' premise is inconsistent with the text of the authorizing statute, which expressly provides that the presumptions in question will be rebuttable, see 30 U.S.C. §§ 921(c)(1), (2), and (4), and requires the Secretary of HEW to consider all relevant evidence in adjudicating claims under part B. See 30 U.S.C. § 923(b). [8]
Second, the presumptions do not by their terms conclusively establish any statutory element of entitlement. In setting forth the two rebuttal methods in subsection (c), the Secretary of HEW did not provide that they would be the exclusive methods of rebuttal. In fact, the claimants admit that "conclusively presume" is a term they "coined" for purposes of argument. Tr. of Oral Arg. 34. Although the delineation of two methods of rebuttal may support an inference that the drafter intended to exclude rebuttal methods not so specified, such an inference provides no guidance where its application would render a regulation inconsistent with the purpose and language of the authorizing statute. See Sunstein, 90 Colum.L.Rev., at 2109, n. 182 (recognizing that the principle expressio unius est exclusio alterius "is a questionable one in light of the dubious reliability of inferring specific intent from silence"); cf. Commercial Office Products Co., 486 U.S., at 120, 108 S.Ct., at 1674 (plurality opinion) (rejecting the more natural reading of statutory language because such an interpretation would lead to "absurd or futile results . . . plainly at variance with the policy of the legislation as a whole") (internal quotations omitted).
In asserting that the Secretary's interpretation is untenable, the claimants essentially argue that the Secretary is not justified in interpreting the HEW interim regulations in conformance with their authorizing statute. According to the claimants, the HEW officials charged with administering the black lung benefits program and with drafting the HEW interim regulations believed that it was virtually impossible to determine medically whether a miner's respiratory impairment was actually caused by pneumoconiosis or whether his total disability arose out of his coal mine employment. Faced with such medical uncertainty, and instructed to ensure the "prompt and vigorous processing of the large backlog of claims," see 20 CFR § 410.490(a) (1990), the claimants assert that HEW omitted from its criteria factual inquiries into disability causation and the existence of pneumoconiosis based on a "cost/benefit" conclusion that such inquiries would engender inordinate delay yet generate little probative evidence. [9] The dissent presents a similar view. Post, at 716-719.
We recognize that the SSA, under the HEW interim regulations, appeared to award benefits to miners whose administrative files contained scant evidence of eligibility. See The Comptroller General of the United States, General Accounting Office, Report to Congress: Examination of Allegations Concerning Administration of the Black Lung Benefits Program 6-10, included in Hearings on H.R. 10760 and S. 3183 before the Subcommittee on Labor of the Senate Committee on Labor and Public Welfare, 94th Cong., 2d Sess., 440-444 (1976). We are not, however, persuaded that this circumstance requires the Secretary to award black lung benefits to claimants who do not have pneumoconiosis or whose disability did not arise in whole or in part out of coal mine employment. As an initial matter, contemporaneous analyses of claims approved by the HEW provide little support for the argument that the HEW made a "cost/benefit" decision to forgo inquiry into disease existence or disability causation. Rather, many of the claims allegedly awarded on the basis of insufficient evidence involved miners who were unable to present sufficient evidence of medical disability, not those who did not suffer from pneumoconiosis or were disabled by other causes. See ibid.; see also, The Comptroller General of the United States, General Accounting Office, Program to Pay Black Lung Benefits to Miners and Their Survivors-Improvements Are Needed, 45-47 (1977); H.R.Rep. No. 95-151, pp. 73-74 (1977) (Minority Views and Separate Views). Moreover, this argument ignores entirely the advances in medical technology that have occurred since the promulgation of the HEW interim regulations, advances that Congress could not have intended either the HEW or the DOL to ignore in administering the program. See S.Rep. No. 95-209, p. 13 (1977).
Finally, we do not accept the implicit premise of this argument: that the Secretary cannot prevail unless she is able to demonstrate that her interpretation of the HEW interim regulations comports with HEW's contemporaneous interpretation of those regulations. As is stated above, the Secretary's interpretation of HEW's interim regulations is entitled to deference so long as it is reasonable. An interpretation that harmonizes an agency's regulations with their authorizing statute is presumptively reasonable, and claimants have not persuaded us that the presumption is unfounded in this case.
We conclude that the Secretary of Labor has not acted unreasonably, or inconsistently with § 402(f)(2) of the Federal Mine Safety and Health Act of 1977 as amended by the Black Lung Benefits Act, in promulgating interim regulations that permit the presumption of entitlement to black lung benefits to be rebutted with evidence demonstrating that the miner does not, or did not, have pneumoconiosis or that the miner's disability does not, or did not, arise out of coal mine employment. Accordingly, we affirm the judgment of the Third Circuit in No. 89-1714. The judgments of the Fourth Circuit in No. 90-113 and No. 90-114 are reversed, and those cases are remanded for further proceedings consistent with this opinion. No costs are allowed in any of these cases.
It is so ordered.

Notes
[edit]- ↑ Pneumoconiosis was identified by the Surgeon General as "a chronic chest disease caused by the accumulation of fine coal dust particles in the human lung." S.Rep. No. 95-209, p. 5 (1977). What he described as simple pneumoconiosis seldom produces significant ventilation impairment, but it may reduce the ability of the lung to transfer oxygen to the blood. Complicated pneumoconiosis is a more serious disease, for the patient "incurs progressive massive fibrosis as a complex reaction to dust and other factors." In its complicated stage, pneumoconiosis "usually produces marked pulmonary impairment and considerable respiratory disability." Ibid.
- ↑ Although the 1972 amendments did not direct the Secretary of HEW to promulgate these new interim regulations, the Report of the Senate Committee on Labor and Public Welfare contained a strongly worded invitation to do so. See S.Rep. No. 92-743, p. 18 (1972), U.S.Code Cong. & Admin.News 1972, p. 2322 ("Accordingly, the Committee expects the Secretary to adopt such interim evidentiary rules and disability evaluation criteria as will permit prompt and vigorous processing of the large backlog of claims consistent with the language and intent of these amendments").
- ↑ In light of this Court's decision in Sebben, the Court of Appeals interpreted § 410.490(c) as permitting rebuttal of the presumption on a showing that the claimant's disability was not caused by coal mine employment. 895 F.2d, at 183. The court therefore remanded the case for further consideration of that issue. It appears that the Fourth Circuit has since retreated from this view, and now considers the HEW interim regulations to permit only two rebuttal methods. See Robinette v. Director, OWCP, 902 F.2d 1566 (CA4 1990) (judgment entry), cert. pending, No. 90-172.
- ↑ In light of this conclusion, the Board found it unnecessary to review the determination that Consolidation had successfully rebutted the presumption under subsection (b)(2) of the DOL interim regulations.
- ↑ In addition to the Third Circuit, the Seventh Circuit has concluded that the third rebuttal provision of the DOL interim regulation is not more restrictive than the criteria applied by the HEW. See Patrich v. Old Ben Coal Co., 926 F.2d 1482, 1488 (1991). The Seventh Circuit did not address the fourth rebuttal provision. The Sixth Circuit also has refused to invalidate the third and fourth rebuttal provisions of the DOL interim regulation, and continues to apply these provisions to all part C claims, regardless of whether the presumption is invoked under § 410.490 or § 727.203. See Youghiogheny and Ohio Coal Co. v. Milliken, 866 F.2d 195, 202 (1989).
- ↑ In Sebben, the Court concluded that the DOL interim regulations were more restrictive than the HEW's to the extent that the DOL's invocation provision did not permit invocation of the presumption without 10 years of coal mining experience. See 488 U.S., at 113, 109 S.Ct., at 419. The Sebben Court did not address the issue now before us: the validity of the third and fourth rebuttal provisions contained in the DOL interim regulations. See id., at 119, 109 S.Ct., at 423.
- ↑ The Court's conclusion in Sebben that subsection (b)(2) of the HEW's interim regulations was not a rebuttal provision does not foreclose the Secretary's argument, as the Sebben Court made clear that that provision was, nonetheless, a "substantive requirement." See Sebben, 488 U.S., at 120, 109 S.Ct., at 423. We agree with the Patrich court that "there is no meaningful difference between a procedure which creates a presumption and then allows evidence to rebut it and one which denies the presumption in the first place if the same evidence is offered." See Patrich, 926 F.2d, at 1488.
- ↑ That no element of the presumptions at issue was intended to be conclusive is further indicated by the language of the remaining two provisions in this section of the statute. In § 921(c)(3), Congress demonstrated its ability to create an irrebuttable presumption, applicable to a miner for whom the medical evidence demonstrates the presence of complicated pneumoconiosis. Perhaps more telling is § 921(c)(4), the only section of the statute in which Congress addressed the available methods of rebuttal. In that section, Congress created a rebuttable presumption of eligibility applicable to a miner with 15 years or more of coal mine employment, for whom evidence demonstrates the existence of a totally disabling respiratory disease but whose X rays do not reveal complicated pneumoconiosis. With respect to this presumption, Congress expressly provided: "The Secretary may rebut such presumption only by establishing that (A) such miner does not, or did not, have pneumoconiosis, or that (B) his respiratory or pulmonary impairment did not arise out of, or in connection with, employment in a coal mine." Written as a limiting provision, this section indicates Congress' understanding that these rebuttal methods are among those permitted with respect to other presumption provisions.
- ↑ The claimants support this argument by reference to the HEW's Coal Miner's Benefits Manual (1979), which they claim represents the agency's contemporaneous interpretation of its regulation. Claimants assert that the Manual "nowhere suggests" that the HEW interim regulations permit factual inquiry into the existence of pneumoconiosis or disability causation. The Manual, however, does not demonstrate that HEW understood its interim regulations to preclude rebuttal with facts similar to DOL's third and fourth rebuttal provisions. At best, this document is ambiguous with respect to the statutory elements susceptible of rebuttal. See Manual § IB6(e) (stating that the presumption of entitlement to benefits "may be rebutted if . . . (3) Biopsy or autopsy findings clearly establish that no pneumoconiosis exists"). We find it more revealing that, in outlining the general structure of the interim regulations, the Manual makes clear that "[t]o establish entitlement to benefits on the basis of a coal miner's total disability due to pneumoconiosis, a claimant must submit the evidence necessary to establish that he is a coal miner . . . who is . . . totally disabled due to pneumoconiosis, and that his pneumoconiosis arose out of employment in the Nation's coal mines." § IB1.
