________________________
COFFIN, Senior Circuit Judge. This case comes before us on
____________________
a petition for review of a provision of a final order of the
Benefits Review Board ("Board") that awarded Bath Iron Works
("BIW") Section 8(f) relief under the Longshore and Harbor
Workers' Compensation Act, 33 U.S.C. 901-950 (1988) ("LHWCA").
Section 8(f) of the LHWCA provides that an employer obliged to
pay disability benefits to an employee may be relieved from full
liability if the employee's compensable disability was
"materially and substantially greater" as a result of a prior,
non-work-related disability.1 The Director, Office of Workers'
Compensation Programs ("OWCP"), appeals the Section 8(f) award to
BIW on a number of grounds, most of which are unnecessary for us
to reach, because we find that the Administrative Law Judge
("ALJ") failed to determine, and the record contains insufficient
evidence to show, that the required standard of "materially and
substantially greater" was met. We therefore grant the petition
for review and reverse the Section 8(f) award.
Claimant Frank H. Johnson worked as a pipe-fitter at the BIW
shipyard for various periods from 1951 until his retirement in
____________________
1 The issue in this case concerns who should bear the
primary responsibility for paying compensation to the claimant.
Under the LHWCA, the employer pays the full amount unless it
meets the requirements set forth in Section 8(f), in which case
its liability for payment to disabled employees is limited to 104
weeks and any remaining compensation owed is paid by a special
second injury fund. 33 U.S.C. 908(f)(1) & (2)(A). The fund
consists of contributions from carriers and self-insured
employers, and is intended to distribute among all employers the
cost of compensating employees, while ensuring that employees
with disabilities receive full benefits for their work-related
injuries. Bath Iron Works Co. v. Director, OWCP, 950 F.2d 56, 58

January 1984. During his employment at BIW, he was exposed to
and inhaled asbestos dust and fibers at the shipyard. Claimant's
exposure ended in 1978 or 1979, when the crumbling asbestos in
his work area was sealed.
In 1986 claimant was diagnosed as suffering from a twenty-
five percent impairment due to asbestosis, and he successfully
filed a claim for workers' compensation benefits under the LHWCA
based on that impairment. The ALJ's award of Section 8(f) relief
to BIW became a final order for the purposes of obtaining
judicial review before us after the Board failed to take action
on the Director's appeal within a year.2
Because the appropriateness of Section 8(f) relief turns on
the source and nature of claimant's pulmonary impairment, we must
examine closely the medical evidence in the record.
THE MEDICAL EVIDENCE
The earliest evidence that claimant suffered from an
asbestos-related lung condition appears to have come in 1982 from
____________________
2 Another ALJ initially awarded BIW Section 8(f) relief
from full liability based on evidence that claimant suffered from
a pre-existing knee injury, as well as "other medical
conditions," all of which were manifest during the period of
claimant's employment at BIW and contributed to his overall
disability. The Director, OWCP, successfully appealed the
Section 8(f) award, and the Board remanded the case, concluding
that claimant's knee condition could not be used as a basis for
relief because it was unrelated to his pulmonary impairment. The
Board directed the ALJ on remand to consider whether the "other
medical conditions" by themselves formed a basis for Section 8(f)
relief. We review the remand decision here.

a routine chest x-ray performed prior to a knee operation.3
According to Dr. Schall, claimant's treating physician, the x-ray
revealed "interstitial fibrosis and pleural plaques consistent
with asbestosis."6 Multiple pulmonary function tests conducted
from that time through 1986 revealed that claimant suffered from
diminished lung function.
Dr. Schall, in a letter dated December 1983, summarized
claimant's condition at that time,
His most recent chest x-ray taken May 19, 1983 showed
pulmonary findings of a thickened pleura with some
calcific pleuritides over the diaphragm and increased
pulmonary markings inferiorly. He still has no
significant complaints of shortness of breath. His
pulmonary functions and chest x-rays show a mixture of
chronic obstructive pulmonary disease and asbestosis
with some restrictive component.[7] Certainly,
asbestosis can be considered a contribution . . . [to]
his pulmonary status. He is currently not disabled on
a pulmonary basis and would be capable of full-time
regular employment. At the present time it's
impossible to predict what his prognosis is. Certainly
his chronic obstructive pulmonary disease is far more
risky to him and is in a further advanced state than is
his asbestosis. He has the concomitant problems of
obesity, chronic alcoholism and severe osteoarthritis
____________________
3 Dr. Schall stated that claimant showed some evidence of
asbestos exposure as early as 1978. As there is no evidence in
the medical record indicating physical damage resulting from
asbestos exposure before 1982, we agree with the ALJ's
determination that claimant's asbestos-related lung condition is
properly dated back to 1982.
6 After this diagnosis, claimant filed a protective
claim, thereby satisfying the LHWCA's notice requirements.
7 In reporting on claimant's condition, Dr. Schall refers
to claimant's "obstructive" pulmonary function and his
"restrictive" pulmonary function. The former is claimant's
condition independent of asbestosis, while the latter is his
asbestos-related condition.

of his knees. His primary disabling feature is his
knees.8
In deposition testimony in 1988, Dr. Schall described the
claimant's condition as "severe obstructive with mild to moderate
restrictive disease."
Dr. Killian, a physician specializing in respiratory
medicine, in a March 1986 letter reporting upon his recent
examination of claimant, concluded that claimant suffered from
five conditions: asbestosis of the left lower lobe, pleural
plaques, obesity, hypertension, and chest pain suggestive of
ischemic heart disease. He added that claimant "does indeed have
both pleural plaques and asbestosis which is due to his asbestos
exposure occurring at work. The degree of disability present
from a pulmonary perspective can be classified as mild. . . .
[H]is present impairment has caused noticeable disability within
the last year or so." In deposition testimony in 1988, Dr.
Killian concluded that claimant's cigarette smoking, his obesity,
____________________
8 In this letter, Dr. Schall also gave the following
review of claimant's medical history:
The man was first seen in 1978 for a routine
examination prior to arthroscopic examination of his
knees. He had at that time a smoking history that
included in excess of 100 pack years but had been off
cigarettes for eight months. He denied shortness of
breath stating that his knees limited his physical
activities. He had a history of hypertension. He's
worked as a pipe-fitter and has been exposed to
asbestos through his work environment. His physical
findings at that time showed his chest to be clear with
a fair respiratory expansion. Chest x-rays at that
time showed some pulmonary scarring consistent with
asbestosis.
-5-
his arthritic knees and lung damage caused by asbestos exposure
contributed to claimant's overall disability.
In 1987 a pulmonary specialist, Dr. Corbin, examined
claimant and reviewed his pulmonary function tests. He
concluded,
I believe that Mr. Johnson has asbestos-related pleural
disease and pleural fibrosis. . . . I am certain that
this was related to his exposure to asbestos during the
time of his employment at Bath Iron Works. . . . Mr.
Johnson also has restrictive lung disease which is mild
to moderate in degree. . . . I feel certain that this
is related to his pleural fibrosis. The patient is
obese, but patients with obesity alone rarely have
restrictive pulmonary function. As I have stated
before, I think his pleural fibrosis is related to his
employment at Bath Iron Works. . . . [H]is symptoms of
shortness of breath and restricted activity are
significantly contributed to by his physical
deconditioning and obesity.
Another physician, Dr. Schmidt, reviewed claimant's June 11,
1982 pulmonary function studies and concluded that they showed
"restrictive lung disease and minimal obstructive airway
disease." He also reported that claimant's January 20, 1983
pulmonary function studies showed "mild obstructive airway
disease," which "appears to be new since June, 1982."
In 1986 claimant, for the first time, was diagnosed as
permanently partially disabled as a result of asbestosis. It is
undisputed that claimant was twenty-five percent partially
disabled at that time. No finding was made as to what amount of
this disability was specifically attributable to asbestosis or to
any other kind of pulmonary impairment.

ENTITLEMENT TO SECTION 8(f) RELIEF --
PERMANENT TOTAL AND PARTIAL DISABILITY CRITERIA DISTINGUISHED
We review the Board's decision for errors of law,9 and
examine the record to determine whether the ALJ's findings are
supported by substantial evidence. 33 U.S.C. 921(b)(3); CNA

Insurance Co. v. Legrow, 935 F.2d 430, 434 (1st Cir. 1991).
_____________ ______
This appeal raises numerous complex issues concerning the
application of Section 8(f). We believe this case can be
resolved on a fairly straightforward basis not requiring us to
consider many of the issues raised on appeal. As we discuss
below, unless the employer establishes that the employee's
compensable permanent partial disability was "materially and
substantially greater" as a result of a prior disability, a
Section 8(f) award is unavailable to the employer, and no further
analysis is required. Because existing case law has largely
ignored the clear threshold requirements of Section 8(f),
however, we think it helpful to clarify certain preliminary
issues in the Section 8(f) framework. We choose, therefore, to
review in detail the initial steps that must be met to support an
award of Section 8(f) relief, up to and including consideration
of the "materially and substantially greater" standard; we do not
consider issues raised on appeal that go beyond these threshold
requirements.

9 In this case, because the ALJ order is final as a
result of the Board's failure to consider the Director's appeal
within one year, we treat the ALJ's order as the Board's
decision.

The LHWCA provides compensation for the death or disability
of federal maritime employees if the disability or death results
from a work-related injury. Under what has been termed the
"aggravation rule," the LHWCA requires an employer to provide
full coverage for a worker's job-related disability even when the
disability resulted from some combination of a current employment
injury and a pre-existing condition. Ceres Marine Terminal v.
______________________
Director, OWCP, 118 F.3d 387, 389 (5th Cir. 1997). In response
______________
to concern that this "aggravation rule" would give the employer
an incentive to discriminate against partially disabled workers
based on a fear of increased liability, Congress enacted Section
8(f). Id.; see also CNA, 935 F.2d at 435 (explaining that the
___ ___ ____ ___
statute was aimed at encouraging employers to hire or continue to
employ handicapped workers by limiting liability for a
subsequently incurred permanent partial disability attributable
in part to a previously existing handicap).
Section 8(f) provides in relevant part:
(f) Injury increasing disability:
(1) In . . . cases of total permanent disability . . .
found not to be due solely to that injury, of an
employee having an existing permanent partial
disability, the employer shall provide . . .
compensation payments . . . for one hundred and four
weeks only. . . .
In . . . cases in which the employee has a
permanent partial disability, found not to be due
solely to that injury, and such disability is
materially and substantially greater than that which
would have resulted from the subsequent injury alone,
the employer shall provide . . . compensation for one
hundred and four weeks only.
33 U.S.C. 908(f)(1).
-8-
The employer carries the burden to prove that the elements
of Section 8(f) are met. See Director, OWCP v. Edward Minte Co.,
___ ______________ _________________
Inc., 803 F.2d 731, 737 (D.C. Cir. 1986); Director, OWCP v.
____ ______________
Newport News Shipbuilding & Dry Dock Co., 676 F.2d 110, 115 (4th
_________________________________________
Cir. 1982).
To qualify for the limitation on full liability, the
employer therefore must prove that the claimant had a permanent
partial disability within the meaning of Section 8(f), and that
the condition existed prior to the work-related injury. We have
described the standard for "disability" under Section 8(f) as "[a
condition] serious enough to motivate a cautious employer either
not to hire or [to] fire [the] employee because of the 'greatly
increased risk of [an] employment-related accident and
compensation liability.'" CNA, 935 F.2d at 435. Thus, a person
___
may be found to suffer from a pre-existing disability even if
able to work full time in the identical position. The pre-
existing disability must, however, be a "condition," and not
merely an unhealthy behavior likely to lead to a condition. See
___

______________________ _________
(finding that an employee's habit of smoking moderately for ten
years prior to developing asbestosis as a result of exposure at
work did not constitute a qualifying prior permanent partial
disability so as to limit an employer's liability under Section
8(f)). To qualify as pre-existing, the condition must exist
before the work-related injury; a disability that occurs
simultaneously will not meet the requirement. See Fineman v.

F.2d 548 (4th Cir. 1991)).
Once the employer establishes that the employee had a
qualifying pre-existing disability, the scope of the compensable
injury must be considered. Although most cases have failed to
acknowledge the differing standards, the proper analysis at this
point turns on whether the employee suffers from a full or
partial disability.
In cases where the employee is fully disabled, the employer
must show that the disability is not due solely to the most
recent injury. E.P. Paup Co. v. Director, OWCP, 999 F.2d 1341,

_____________________________ _________
OWCP, 913 F.2d 1426, 1429 (9th Cir. 1990). "Thus, if the
____
employment injury was sufficient, by itself, to cause the
claimant's total permanent disability, the employer should be
liable for the entire compensation award and section 8(f) relief
should be denied. The aggravation rule that [S]ection 8(f) was
intended to counteract never comes into play under these
circumstances because the employer would be liable to the same
extent if an able-bodied employee suffered the same injury."
Ceres Marine, 118 F.3d at 390. The employer cannot satisfy the
_____________
Section 8(f) standard merely by demonstrating that the employee's
pre-existing injury compounded his employment-related injury;
rather, the employer must show that, but for pre-existing
-10-
disability, claimant would be employable. Director, OWCP v.

To satisfy this additional prong, the employer must

resulted from the work-related injury alone. A showing
of this kind requires quantification of the level of
impairment that would ensue from the work-related
injury alone. In other words, an employer must present
evidence of the type and extent of disability that the
claimant would suffer if not previously disabled when
injured by the same work-related injury. Once the
employer establishes the level of disability in the
absence of a pre-existing permanent partial disability,

disability is materially and substantially greater.
8 F.3d at 185-86; see also Ingalls, 1997 WL 612743, *4. Thus, an
___ ____ _______
employer is required to show the degree of disability
attributable to the work-related injury, so that this amount may
be compared to the total percentage of the partial disability for
which coverage under the LHWCA is sought.
The court in Newport News specifically rejected the argument
____________
that an employer need only show medical evidence that a
percentage of whole body impairment existed before the work-
related injury, that a greater percentage of whole body
impairment exists after the work-related injury, and that the
ultimate permanent partial disability was causally connected to
the earlier impairment to satisfy its burden of the contribution
element:
[Such a] showing eviscerates the requirement from
section 8(f) that the ultimate permanent partial
disability be materially and substantially greater than
a disability from the work-related injury alone would
be, by overlooking the possibility that the work-
related injury alone could cause virtually the same
level of disability as that manifested in the ultimate
permanent partial disability through the contribution
of the pre-existing permanent partial disability.
8 F.3d at 184.
Despite the clear statutory language of Section 8(f), and
despite cases such as Newport News and Ingalls, emphasizing the
____________ _______
need to meet the "materially and substantially greater" standard
in partial disability cases, some cases have permitted a looser
contribution finding, or have failed to consider the standard at

all. See, e.g., Skelton v. Bath Iron Works Corp., 27 BRBS 28, *2
___ ____ _______ _____________________
(1993) (stating that the Section 8(f) contribution requirement
may be met by a showing "that the pre-existing disability was
aggravated by claimant's subsequent employment."). However, a
finding that a claimant's permanent physical impairment is
greater as a result of the combination of the pre-existing and
work-related injuries is clearly insufficient to satisfy Section
8(f). See Newport News, 8 F.3d at 184-85. Failure to apply the
___ ____________
statutory criteria of "materially and substantially greater"
constitutes error.
BIW'S SECTION 8(f) BURDEN APPLIED
I. The ALJ's Findings and Conclusions
__________________________________
The ALJ defined the essential elements for Section 8(f)
relief as: "(1) the employee had a pre-existing permanent
partial disability, (2) which was manifest to the employer prior
to the subsequent compensable injury, and (3) which combined with
the subsequent injury to produce or increase the employee's
permanent total or partial disability, a disability greater than
that resulting from the first injury alone." In concluding that
BIW met these elements, the ALJ relied on the following:
The record reflects . . . (2) that [claimant] has
experienced shortness of breath and pulmonary problems
since at least May of 1978 as he was required to be
examined by Dr. Schall for pre-operative clearance
prior to knee surgery, (3) that he has suffered from
obesity and hypertension for many years, (4) that he
had a long history of cigarette smoking, i.e., at least
1 to 3 packs per day for forty years, a habit he
stopped in 1978, (5) that Claimant's asbestos-related
disease was first reported on his chest x-rays in April
-13-
of 1982, . . . (7) that his subsequent diagnostic
tests, including pulmonary function tests, showed an
increase of his asbestos-related disease and a
worsening of his shortness of breath, (8) that Dr.
Schall, as of December 5, 1983, opined that Claimant's
pulmonary impairment was due to "a mixture of chronic
obstructive pulmonary disease and asbestosis with some
restrictive component," (9) that Claimant's "chronic
obstructive pulmonary disease is far more risky to him
and is (in) a further advanced state than is his
asbestosis," (10) that he "has the concomitant problems
of obesity, chronic alcoholism and severe
osteoarthritis of his knees," . . . (12) that the
doctors are in agreement that Claimant's permanent
partial impairment is due to the combination of his
asbestos-related disease, i.e., his asbestosis, his
hypertension, his obesity, his cardiac problems
diagnosed as ischemic heart disease, (13) that the
doctors reiterated their opinions at their post-hearing
depositions . . . , [and] (14) that Claimant's
permanent disability is the result of the combination
of his pre-existing permanent partial disability (i.e.
his pulmonary problems since at least May 18, 1978, his
chronic obesity, his chronic hypertension, his cardiac
problems and his cigarette smoking habit of at least
100 pack years and as high as 120 pack years) and his
work-related asbestosis . . . [. His] pre-existing
disability, in combination with the subsequent work
injury, has contributed to a greater degree of
permanent disability, according to Dr. Schall, Dr.
Corbin and Dr. Killian. (citations to record omitted).
The ALJ concluded from the evidence that claimant fit the
category of person that Section 8(f) was designed to protect:
"Claimant's condition, prior to his injury in 1986, was the
classic condition of a high-risk employee whom a cautious
employer would neither have hired nor retained in employment due
to the increased likelihood that such an employee would sustain
another occupational injury."
-14-
Other than what is included in a citation from another case,
quoted for a different proposition,11 the ALJ in no place
mentions the Section 8(f) requirement, or makes a finding, that
the ultimate permanent disability is materially and substantially
greater as a result of the preexisting disability than the
disability which would have resulted from the subsequent injury
alone.
II. The Missing Assessment: the ALJ Opinion and the Record
______________________________________________________
Under the LHWCA, Johnson's compensable injury occurred in
1986, when he was diagnosed with a twenty-five percent permanent
disability resulting from asbestosis.12 Therefore, only the non-
____________________
11 At the conclusion of the order, the ALJ quoted Adams v.
_____
Newport News, 22 BRBS 78, 85 (1989), for the proposition that
____________
only pulmonary problems were relevant to the Section 8(f)
determination; physical problems relating to other impairments,
such as claimant's knee injury, could not be considered. In the
section of Adams quoted by the ALJ, the Board mentions the
_____
"materially and substantially greater" requirement only as part
of its general explanation that this standard must be met by a
pre-existing disability that impacts the same type of physical
functioning as does the work-related injury.
12 In long-latency disease cases, such as asbestosis,
using the date of last exposure as the relevant time of injury is
inappropriate because the injury arises years later when the
disease manifests itself. See Bath Iron Works Co., 506 U.S. at
___ ____________________
163. Therefore, while not determinative of our finding, we note
here the applicable date for time of injury is the date that
claimant was diagnosed with -- and thus became aware that he
suffered from -- a twenty-five percent permanent partial
disability resulting from asbestosis. See Harris, 934 F.2d at
___ ______
553 (stating that "the time of injury is deemed to be the date on
which the employee or claimant becomes aware, or in the exercise
of reasonable diligence or by reason of medical advice should
have been aware, of the relationship between the employment, the
disease, and the death or disability," citing 33 U.S.C. 910(i)
and noting, "[s]ince the issue before the court is how long the
employer is going to have to pay the amount determined to be due
under [Section 910], it necessarily follows that the definition
of time of injury found therein would be used for the purposes of
-15-
asbestosis-related pulmonary disability that he suffered prior to
1986 is relevant to our Section 8(f) analysis.
Claimant suffered from pulmonary problems, including
obstructive pulmonary conditions unrelated to asbestos prior to
1986. The evidence in the medical record supports the ALJ's
conclusion that these problems, probably resulting from obesity
and smoking, amounted to "the classic condition of a high-risk
employee whom a cautious employer would neither have hired nor
retained in employment due to the increased likelihood that such
an employee would sustain another occupational disease." While
we need not reach this issue to conclude this case, we note here
that we agree with the ALJ's finding that claimant met the
Section 8(f) criteria of suffering from a pre-existing permanent
disability prior to his work-related injury.
To be entitled to Section 8(f) relief, however, BIW was
required to carry the burden of demonstrating that claimant's
twenty-five percent disability was materially and substantially
greater than that which would have resulted from the asbestos
exposure alone. To do this, BIW was required to show the degree
of disability attributable only to claimant's asbestosis. See
___
Newport News, 8 F.3d at 185-86. Then, the ALJ should have
_____________
compared this information with claimant's twenty-five percent
disability to determine whether the "materially and substantially
greater" standard had been met. See id.
___ ___
____________________
Section 8(f).").
-16-
The ALJ, however, made no such determination. He neither
discussed the statutory requirement, nor applied it in analyzing
the facts of this case.
Further, the ALJ lacked the evidence to apply the
"materially and substantially greater" standard even had he
chosen to do so. No evidence of the degree of disability
attributable only to claimant's asbestosis was ever presented.
Nor can such disability be deduced from the medical records
relating to claimant's non-asbestos-related injury. While Dr.
Schall did state that the non-related asbestos lung disease was
in a further advanced state than claimant's asbestosis, Dr.
Schall made this diagnosis in 1983. At that time, claimant was
not disabled as a result of pulmonary impairment. A 1983
assessment, therefore, could not establish the degree to which
claimant's 1986 compensable injury was impacted by an earlier
existing non-asbestos-related disability. Dr. Killian, in
reporting on claimant's condition in 1986, concluded that
claimant's prior non-asbestos-related disability contributed to
claimant's overall disability. But he gave no indication of how
much contribution existed, and included in his assessment of
claimant's "overall disability" claimant's knee problems, which
cannot properly form part of a Section 8(f) determination. Dr.
Corbin provides the best evidence for BIW, stating, in 1987, that
claimant's "symptoms of shortness of breath and restricted
activity are significantly contributed to by his physical
deconditioning and obesity." However, even this report fails to
-17-
meet the required standard. Dr. Corbin provides a general
statement that includes claimant's shortness of breath and spans
his "restricted activity." The report does not indicate the
extent to which claimant's pre-existing condition contributed to
his permanent partial disability, the twenty-five percent
pulmonary impairment for which condition alone claimant received
compensation under the LHWCA.
Therefore, there being neither sufficient direct evidence of
the contribution of asbestosis to claimant's overall permanent
partial disability nor a basis for deducing such contribution
from the contribution attributable to the pre-existing condition,
BIW has failed to carry its considerable burden.
-18-
CONCLUSION
Because we determine that the ALJ failed to find, and the
record contains insufficient evidence to show, that claimant's
current permanent partial disability is materially and
substantially greater than that which would have resulted from
asbestosis alone, we do not address the remaining issues raised
by appellant. For the reasons discussed, we reverse the Section
8(f) award to BIW.
