                            DECISION

Appearances:  R. Henry Moore, Esq., Buchanan Ingersol, P.C., Pitts-
              burgh, Pennsylvania, for Contestant;
              Kristi  L.  Floyd,  Esq., Office of the Solicitor,
              U.S. Department of Labor, Denver, Colorado, for Re-
              spondent.

Before:  Judge Zielinski

     These cases are before me on notices of contest filed by The
Doe  Run Company against the Secretary  of  Labor  and  her  Mine
Safety  and  Health Administration (MSHA) pursuant to Section 105
of the Federal Mine Safety and Health Act of 1977, 30 U.S.C. � 815
(the  "Act").  The company contests  the  issuance  of  four
citations alleging  violations  of  a mandatory health and safety
standard,  30  C.F.R.  �  57.11050(a), which  requires  that  two
escapeways be maintained from  the "lowest levels" of underground
metal and non-metal mines.  A hearing  was  held on May 31, 2000,
in St. Louis, Missouri.  Following receipt of the transcript, the
parties   submitted  briefs  on  August  21,  2000.    Contestant
submitted a  reply  brief  on  August  28,  2000.   The Secretary
elected not to submit a reply brief.  For the reasons  set  forth
below  I find that the Secretary's interpretation of the standard
is  entitled   to  deference,  but,  due  process  considerations
preclude enforcement of that interpretation against Doe Run here.

                 The Evidence - Findings of Fact

     The relevant  facts  are  not  in dispute.  Doe Run operates
eight  underground  lead, zinc and copper  mines,  including  the
three mines at which  the  subject  citations were issued, Buick,
Brushy Creek and Viburnum No. 29.  The  subject mines extract ore
from  a  deposit known as the viburnum trend,  which  runs  in  a
north-south  direction.   While  the  ore  deposit is essentially
horizontal, it angles slightly downward as it  proceeds south, is
somewhat  irregular  in  elevation  and  varies  considerably  in
thickness.  The mines are accessed through shafts.  The Buick and
Brushy  Creek mines have separate production and man  shafts  and
the Viburnum No. 29 Mine has a combined production and man shaft.
The Buick  and  Brushy  Creek  mines have separate production and
haulage levels off of each shaft  and  the No. 29 mine has only a
production level.  The production and man shafts, separate escape
shafts  and connecting mines provide avenues  of  egress  to  the
surface from  the  production  level  of  each mine.  There is no
dispute  that,  in  general,  there  are  at least  two  separate
escapeways from the production level of each of the mines.[1]

     The areas at issue here are discreet locations where Doe Run
uses what is called "multiple pass mining"  to  extract  ore when
the  thickness  of a deposit substantially exceeds the height  of
the normal 16-20  foot high drift of the production level.  After
mining the ore at the  production  level,  Doe Run may make a cut
below  the  production  level,  an  "undercut",  or   above   the
production level, an "overcut."  An undercut is made by cutting a
drift  at  a  downward  angle  from the production drift and then
horizontally into the ore body underneath  the  production drift.
The material between the floor of the production  drift  and  the
ceiling  of  the  undercut  is  called a "sill" and its thickness
generally ranges from 15 to 30 feet,  occasionally up to 50 or 60
feet.  Overcuts are made in the same fashion  by  angling a drift
up from the production drift.  Doe Run also accesses  other parts
of  the ore body directly horizontal to the production drifts  by
cutting a separate drift to such areas, which will be referred to
as "side-cuts".   When these three types of additional cuts reach
the ore body and extraction  of the ore begins, they all have one
significant  characteristic  in   common.   The  work  areas  are
accessed only by a single passageway or drift.  The distance from
the top of the undercut incline to  the working face was 250 feet
in the Buick Mine and 1,000 feet in the Viburnum No. 29 Mine.  No
specific  distances  were  specified  in  the  citations  of  the
undercuts  at  the  Brushy  Creek Mine.  The  lengths  of  single
entrances to "side-cuts" ranged  up  to  2,000  feet,  and  there
appear  to  be  active  workings  at  the southernmost end of the
production level of the Brushy Creek Mine  that are accessed by a
single passageway of a comparable distance.  The map of the Buick
Mine also depicts now-inactive areas at the production level that
were accessed by a single passageway several thousand feet long.

     Multiple pass mining has become prevalent  over the past 6-8
years.  The previous method involved accessing the  ore body near
its  top  and  mining downward in benches, eventually creating  a
void of considerable  height,  e.g.  50-60  feet.   Problems with
scaling  that  high  a  roof  and  drilling  pillars  for removal
rendered that method, in the opinion of Doe Run's managers,  more
dangerous and less efficient than the multiple pass method.  That
testimony was not contradicted by the Secretary.

     The  drifts leading to work areas in undercuts, overcuts and
side-cuts serve  as  the  sole  means  of  ingress and egress for
miners and equipment working in those areas.   The work areas are
ventilated,  at  least initially, by use of a fan  and  vent  bag
system, essentially a fabric tube through which air is blown from
the main production  area.  Various types of rubber tired, diesel
powered equipment access  the  work  area  through  the drifts to
drill, blast and remove the ore.  Each piece of diesel  equipment
is  equipped  with  two  fire  extinguishers  and possibly a fire
suppression  system.   Potential  hazards that could  render  the
drifts unusable as an escapeway, and  which  would  also  curtail
ventilation,  were identified as equipment fires or ground falls.
There was one known  fire  in  the mines, involving a truck, that
occurred around 1987 or 1988.  There  was  no evidence introduced
as  to  the  likelihood  of  a  ground  fall  or  any  such  past
occurrences in the working areas of the mines.[2]

     Where the secondary cut becomes extensive, the  fan and vent
bag  system  of  ventilation  eventually  becomes inadequate  and
additional ventilation may be provided by cutting a shaft through
the sill from the production drift.  Such shafts could provide an
additional avenue of egress from undercuts  and  overcuts,  if  a
ladder was installed in the shaft.  Doe Run's witnesses testified
that  it would take two to three days to cut such a shaft through
a sill  up  to  30  feet  thick,  if no significant problems were
encountered, and that a ladder would cost approximately $1,500.00
to $3,000.00.  There were no such shafts  cut  in the cited areas
because ventilation through the access drift was  then  adequate.
The  cutting  of such a shaft and installation of a ladder  would
have been feasible  in the cited areas in the Viburnum and Brushy
Creek mines.

     However, it was  not feasible in the area cited in the Buick
mine, the "area 1 pillar  undercut."   Where  high  grade  ore is
encountered,  Doe  Run typically extracts the pillars at the main
production drift.  Where the ore body is less than 150 feet wide,
the pillars can simply  be  removed through the production drift.
If wider, however, not all of  the pillars can be removed in that
manner.  Additional roof support  is  provided by backfilling the
mined "rooms" adjoining two or more rows of pillars with rock and
similar  materials  mixed  with  cement.  The  pillars  that  are
"trapped"  in  the  backfill  are  then   removed  by  making  an
"undercut" below them and drilling and blasting  them  down  into
the  undercut,  where  the  ore  is  removed by remote controlled
loaders.  Once pillars are removed, miners  are  prohibited  from
entering the area and cutting a ventilation/escapeway shaft  from
the  production  drift  to  the  undercut  is not feasible.  Some
pillars had been removed, and others entrapped, at the production
level  above  the  "area 1 pillar undercut" in  the  Buick  Mine,
prohibiting installation of a ventilation/escapeway shaft through
the sill.

     Doe Run had used  this mining method for several years prior
to the issuance of the citations.   During  that  time,  MSHA had
conducted  mandated  quarterly  inspections of the mines and  the
"undercut" areas currently in question, which have existed for as
many as four years and possibly longer.  No citations were issued
for violating the two escapeway standard and the propriety of the
undercuts was not otherwise questioned.

     Doyle  D.  Fink  became  manager  of  MSHA's  South  Central
District in 1995.  Because of his concerns about important safety
requirements he directed a review  of  escape  and evacuation and
ventilation plans of the mines in the District.[3]   That  review
brought  to  his  attention that numerous work areas in Doe Run's
mines were accessed  only  by  a  single  drift.  As part of this
special  review  project, he directed that inspections  be  made.
MSHA inspector Robert  Seelke,  an experienced MSHA inspector who
had inspected Doe Run's mines during  the  13  years  he had been
assigned  to  the  South  Central  District,  inspected the mines
beginning in July of 1999.   After reviewing the  results  of his
inspections,  the  information  gathered  from  the review of the
escape and evacuation and ventilation plans and discussions  with
mine personnel, MSHA determined to issue citations for violations
of  30 C.F.R.� 57.11050(a), the standard requiring two escapeways
in these  metal,  non-metal  mines.  A total of 17 citations were
issued in September of 1999, citing locations at six of the mines
for purported violations of the standard, which provides:

     � 57.11050 Escapeways and refuges.

          (a) Every mine shall  have  two  or more separate,
     properly maintained escapeways to the surface  from the
     lowest  levels  which are so positioned that damage  to
     one shall not lessen  the  effectiveness of the others.
     A method of refuge shall be  provided  while  a  second
     opening  to  the  surface is being developed.  A second
     escapeway  is recommended,  but  not  required,  during
     exploration  or  development  of an ore body. (emphasis
     supplied)


**FOOTNOTES**

     [1]:  Doe Run provides other safety  measures  for miners who
may  encounter  difficulty exiting a work area.  Rescue  chambers
are provided in certain  areas  and  an  emergency  hoist with an
"escape bullet" is available to remove miners through ventilation
bore holes.

     [2]:  There was testimony that there had been roof  falls  in
Doe  Run's  mines,  but the only area specified was where pillars
had been removed and no miner was allowed to enter.

     [3]:  MSHA either  had  these  documents  on  file,  or could
readily obtain them.

See, 30 C.F.R. �� 57.8520, 57.11053.

     Mr.  Fink's  interpretation  of  the  standard  was  that it
required  two  escapeways  from  each  work area in the mines.[4]
Consequently, citations were issued for  all of the areas entered
by  a  single  drift -- undercuts, overcuts and  side-cuts.   The
wording   of  the  citations,   however,   tracked   Mr.   Fink's
interpretation  of  the  standard, rather than the wording of the
standard itself.  Citation  No.  7884481,  issued on September 9,
1999, for the Viburnum mine, was typical.  It read:

     The  working  area  known  as  78V21 and 78V6  was  not
     provided with at least 2 separate  properly  maintained
     escape ways from that work area.  This area is accessed
     by  a  single  entry  for  approx. 1000' to the working
     faces.  This condition creates  the hazard of employees
     being  trapped  in the mine should  the  only  provided
     escapeway  become  impassable.   Rubber  tired,  diesel
     powered mobile  equipment  is  used  in  this  area for
     ground  control  work,  drilling, loading of explosives
     and to muck ore.  Normally  5 or less employees work in
     this area. (emphasis supplied)

     This citation was modified on September 16, 1999, to specify
a  violation  of � 11050(b), which requires  refuges  in  certain
situations.  Doe Run contested the citations, as modified.  After
discussions between  MSHA and the Secretary's Solicitor's Office,
the citation was modified  again  on December 3, 1999, to specify
the  applicable  standard  as  � 11050(a),  and  the  highlighted
wording was changed to conform to  the  wording  of the standard.
The first sentence of Citation No. 7884481 now reads:  "The areas
known  as  78V21  and  78V6  were  not  provided with at least  2
separate properly maintained escapeways to the surface  from this
lowest  level."  Similar modifications were  made  to  the  other
three citations.[5]   The  citations of the 13 areas that did not
involve undercuts were vacated,  apparently  in  recognition that
they could not be considered "lowest levels" of the mines.

     The ultimate issue in these cases is whether  the "undercut"
areas  addressed by the citations constitute "lowest  levels"  of
the mines  within  the meaning of � 57.11050(a).  The Secretary's
interpretation of the  standard,  as applied here, has admittedly
not been applied in the past at any  of  Doe  Run's mines and was
developed  during  litigation  of  these and the related  contest
proceedings.  While the other areas  cited, "overcuts" and "side-
cuts",  pose virtually the same hazards as these "undercuts", the
Secretary has tacitly conceded that there  is  no viable argument
that those areas fall within any reasonable definition of "lowest
levels" by vacating the subject citations.[6]

     The parties introduced into evidence several  definitions of
the  word  "level" and related terms  of significance  in  mining
operations.   Both parties rely on parts of the definition of the
term "level" contained  in the U.S. Bureau of Mines, A Dictionary
of   Mining,   Mineral  and  Related   Terms   638   (1968   ed.)
("Dictionary"), which provides, in pertinent part:

     level a.  A  main underground roadway or passage driven
     along  the  level   course  to  afford  access  to  the
     stopes[[7]] or workings  and to provide ventilation and
     haulageways for the removal  of  coal  or ore. * * * b.
     Mines  are  customarily  worked  from  shafts   through
     horizontal passages or drifts called levels.  These are
     commonly  spaced at regular intervals in depth and  are
     either numbered  from  the  surface in regular order or
     designated by their actual elevation below the top of a
     shaft. * * * c.  In pitch mining,  such  as anthracite,
     there  may be a number of levels driven from  the  same
     shaft, each  being  known by its depth from the surface
     or by the name of the  bed  or  seam  in  which  it  is
     driven.  *  *  *  e.   Applied  to seams which run like
     floors in an office building.  Under and above the seam
     lie the rock strata. * * * j.  All  openings at each of
     the  different  horizons  from which the  ore  body  is
     opened up and mining is started. * * *

     Doe Run additionally relies on a definition found in Society
of Mining Engineers, Underground Mining Methods Handbook 88 (1982
ed.) which provides:

     Level: A level is a system  of  horizontal  underground
     workings  that  are  connected  to the shaft.  A  level
     forms  the basis for excavation of  the  ore  above  or
     below.


**FOOTNOTES**

     [4]:  Contrast  the  wording  of  the  escapeway standard for
metal   and   non-metal  mines  with  the  comparable   standards
applicable to coal  mines  which require that separate escapeways
be provided "from each working  section"  of the mine.  30 C.F.R.
�� 75.380(b)(1) and 75.381(b).

     [5]:  Citation  No. 7884492 cited an undercut  at  the  Buick
Mine and read, after  modification:  "The  area  known  as area 1
pillar  undercut  was  not  provided  with  at  least  2 separate
properly  maintained  escapeways to the surface from this  lowest
level."  Citation No. 7884505  cited  an  undercut  at the Brushy
Creek  Mine and read, after modification: "The area known  as  76
bottom was  not  provided  with  at  least  2  separate  properly
maintained  escapeways  to  the  surface from this lowest level."
Citation No. 7884506 also cited an  undercut  at the Brushy Creek
Mine and read, after modification: "The area known  as 9 undercut
was  not  provided  with  at least 2 separate properly maintained
escapeways to the surface from this lowest level."

     [6]:  Undercuts could pose  an  additional  hazard  in  "wet"
areas,  where  water  accumulation  could  drain  into  the lower
elevations.   There  was  one  such  area  involved here, but the
additional  hazard  was  minimal and was described  as  posing  a
significant flooding problem  if  a  pump would be inoperable for
two weeks.

     [7]:  The term "stoping" was defined,  in pertinent part, as:
"The act of excavating ore, either above or  below  a level, in a
series of steps.  In its broadest sense stoping means  the act of
excavating  ore by means of a series of horizontal, vertical,  or
inclined workings  in veins or large, irregular bodies of ore, or
by rooms in flat deposits. * * * .
     A "Safety Rule  Book"  developed  by  ASARCO and used by Doe
Run, defined "levels" as "worked or working  areas  of a mine off
the shaft."

     Witnesses called by the parties relied on various  parts  of
these  definitions in testifying that the undercut areas are - or
are not  -  "levels" or "lowest levels" within the meaning of the
standard.   The  Secretary  places  particular  emphasis  on  the
Dictionary's,  subpart  j,  which reads: "All openings at each of
the different horizons from which  the  ore body is opened up and
mining  is started."  Doe Run emphasizes those  portions  of  the
various definitions  that  purport  to require that each level be
separately connected to a shaft and the portion of the Dictionary
definition that refers to stopes as evidencing that undercuts and
overcuts are simply workings accessing  the  ore deposit below or
above the single level of the mines.  The Secretary counters that
levels do not need to be connected to a shaft,  noting that there
are  levels in "adit" mines, which are mines accessed  through  a
horizontal  portal or tunnel and have no shafts.  She also points
out that the  undercuts  are  indirectly  connected  to  a shaft,
albeit not separately from the production level.[8]

     The  Secretary  also  relies upon an exhibit that apparently
originated somewhere in Doe  Run's  operations that sets forth an
explanation of the color scheme used on various mine maps to show
workings at different elevations and  refers to them as "levels."
I  place no significance on that exhibit,  however,  because  its
relationship  to  any  of  the  mines  at  issue  here  was never
established  and  because  there  is  no  evidence  that  whoever
prepared  the  document  intended  to  use  the  terms "level" or
"levels" other than as a general reference to elevation  or  with
even  the  remotest  relationship  to the use of the term "lowest
levels" in the standard.

     Doe Run argues that even if the  "undercuts"  are determined
to  be levels, that they are not the lowest levels of  the  mines
because  portions of the production and/or haulage levels at each
of the mines  are  lower  in elevation than the cited areas.  For
example, the lowest elevation  of  the floor of the cited area in
the Viburnum mine was 482 feet above  sea  level  while the floor
elevation of the main level off the shaft was 446 feet  above sea
level,  some 36 feet lower in elevation.  Such relative positions
can occur because, as noted previously, the ore body is irregular
in thickness  and  is not absolutely horizontal.  The Secretary's
witnesses testified  that  the  term  "lowest  levels" is defined
primarily in functional terms and has little to  do  with  actual
elevation.


**FOOTNOTES**

     [8]:  The  Secretary  also argues that since the incline down
to an undercut can be referred  to  as a "ramp" that the undercut
is a separate level because the Dictionary  defines  "ramp" as an
"incline connecting two levels."  I reject that argument  because
there is no indication that the use of the word "levels" in  that
definition has any relationship to the Dictionary's definition of
"level."   In  fact, the portion of the definition relied upon is
the last of a series of definitions which have nothing to do with
the term "level"  and  it  appears to be referring to "levels" in
the most general sense.

                       Conclusions of Law

     As noted above, the ultimate issue in these cases is whether
the  cited "undercut" areas are  "lowest  levels"  of  the  mines
within the meaning of the safety and health standard, 30 C.F.R.
� 57.11051(a).   The  legal  framework  for  resolving that issue
requires determining whether the regulation is  ambiguous, if so,
whether the Secretary's interpretation can be afforded deference,
and  finally,  whether  Doe  Run  received  fair  notice  of  the
interpretation it was cited for violating.

     The deference portion of the analysis was described  by  the
Commission in Island Creek Coal Co., 20 FMSHRC 14, 18-19 (January
1998):

          Where  the  language  of a regulatory provision is
     clear, the terms of that provision  must be enforced as
     they are written unless the regulator  clearly intended
     the words to have a different meaning or  unless such a
     meaning would lead to absurd results.  Dyer  v.  United
     States,  832 F.2d 1062, 1066 (9th Cir. 1987) (citations
     omitted).   See  also Utah Power & Light Co., 11 FMSHRC
     1926,   1930  (October   1989)   (citations   omitted);
     Consolidation  Coal  Co.,  15 FMSHRC 1555, 1557 (August
     1993).  If, however, a standard  is  ambiguous,  courts
     have    deferred    to   the   Secretary's   reasonable
     interpretation  of the  regulation.   See  Energy  West
     Mining Co. v . FMSHRC,  40  F.3rd  457,  463  (D.C.Cir.
     1994).   Accord  Secretary  of  Labor v. Western Fuels-
     Utah,   Inc.,   900  F.2d  318,  321  (D.C.Cir.   1990)
     ("agency's interpretation  .  .  .  is  `of controlling
     weight  unless it is plainly erroneous or  inconsistent
     with the regulation'") (quoting Bowles v. Seminole Rock
     Co.,
     325 U.S.  410,  414  (1945) (other citations omitted)).
     The  Secretary's  interpretation  of  a  regulation  is
     reasonable where it  is  "logically consistent with the
     language of the regulation  []  and  .  .  .  serves  a
     permissible  regulatory function."  General Electric Co
     v. EPA, 53 F.3d  1324,  1327  (D.C.Cir. 1995) (citation
     omitted).  The Commission's review,  like  the courts',
     involves  an  examination  of  whether  the Secretary's
     interpretation is reasonable.  Energy West,  40 F.3d at
     463 (citing Secretary of Labor on behalf of Bushnell v.
     Cannelton Indus., Inc.,
     867   F.2d  1432,  1439  (D.C.Cir.  1989)).   See  also
     Consolidation Coal Co.,
     14 FMSHRC  956,  969  (June  1992)  (examining  whether
     Secretary's interpretation was reasonable).

     The   Secretary   argues  that  her  interpretation  of  the
regulation is entitled to  deference  in  that  it is not plainly
erroneous  or  inconsistent  with  the  regulatory  language  and
furthers the purposes of the Act.  Doe Run argues, alternatively,
that  the  regulation  is  not ambiguous and that the Secretary's
interpretation is not reasonable  and  has  not been consistently
applied.   Doe  Run  also  argues  that   due  process  precludes
application  of  the  Secretary's interpretation in  these  cases
because it was not fairly  warned  of  the  "new"  interpretation
applied here.  The Secretary, as previously noted, elected not to
file a reply brief and has not directly addressed Doe  Run's  due
process argument.

Ambiguity

     The term "lowest levels" is not defined in either the Act or
the  regulations.  In light of the various definitions introduced
into evidence  and  the parties respective witnesses' opinions as
to whether these "undercuts" were a separate "level" of the mines
and whether they were  "lowest  levels" within the meaning of the
regulation, I have little trouble  concluding that the regulation
is  ambiguous  when applied to these undercuts.   "As  the  Court
stated in Boston & Maine, [503 U.S. 407 (1992)] `[f]ew phrases in
a complex scheme  of  regulation are so clear as to be beyond the
need for interpretation when applied in a real context.'"  Island
Creek Coal Co., supra,  20 FMSHRC at 19.  Ambiguity exists when a
regulation is capable of  being  understood  by  reasonably well-
informed persons in two or more different senses.  Id.

     The Secretary's and Doe Run's witnesses, each of whom easily
qualified   as   reasonably   well-informed   persons,   advanced
diametrically opposed interpretations of the term "lowest levels"
as applied to these undercuts.  Moreover, as discussed more fully
below,   I   find  that  those  respective  interpretations  were
reasonable and were formed by reasonably prudent persons familiar
with the mining  industry  and  the  protective  purposes  of the
standard.   It appears, both from the respective definitions  and
the limited litigation  history  of  the provision, that the term
"level" in the mining context includes  physical  and  functional
components.   See  Savage  Zinc,  Inc.,  17  FMSHRC 279 (February
1995);   Magma  Copper  Co.,  16  FMSHRC  327  (February   1994).
Application  of  the  term "lowest levels" to the "real world" of
the undercuts cited in  these cases demands interpretation of the
term  which  is highly ambiguous  in  this  context.   Doe  Run's
argument that  the  regulation  is  not ambiguous in this context
because the "reasonably prudent person"  could only conclude that
the undercuts were not lowest levels within  the  meaning  of the
regulation must be rejected.

The Secretary's Interpretation - Deference

     It  is  well-established that the Secretary's interpretation
of her own regulations  in  the complex scheme of mine health and
safety is entitled to a high  level  of  deference  and  must  be
accepted  if  it is logically consistent with the language of the
regulation and  serves  a permissible regulatory function.  Kerr-
McGee Coal Corp. v. FMSHRC,  40  F.3d  1257,  121261-62 (D.C.Cir.
1994),  cert.  denied, 115 S.Ct. 2611 (1995); Island  Creek  Coal
Co., supra, and  cases  cited  therein.  Doe Run clearly faces an
uphill battle in seeking to avoid  the Secretary's interpretation
of the regulation.  As described in  General  Electric, supra, 53
F.3d at 1327:

          In  adhering  to  this  policy [of deference],  we
     occasionally   defer   to   "permissible"    regulatory
     interpretations that diverge significantly from  what a
     first-time reader of the regulations might conclude was
     the  "best"  interpretation  of  their  language.   Cf.
     American  Fed.  Gov't  Employees v. FLRA, 778 F.2d 850,
     856 (D.C.Cir. 1985) ("As a court of review . . . we are
     not positioned to choose  from  plausible  readings the
     interpretation  we  think  best." (internal punctuation
     and  citation  omitted)).   We   may  defer  where  the
     agency's reading of the statute would not be obvious to
     "the  most astute reader." Rollins,[[9]]  937  F.2d  at
     652.  And  even  where  the  petitioner advances a more
     plausible reading of the regulations  than that offered
     by  the  agency,  it  is  "the  agency's choice  [that]
     receives substantial deference." Id.

     As noted above, I find the respective interpretations of the
term  "lowest levels" offered by the parties  to  be  reasonable.
Doe Run's  reliance on aspects of the various definitions to urge
that the undercuts  and  overcuts  are  not  separate  levels but
merely in the nature of stopes where excavation of the ore  above
or   below   the  production  level  occurred,  is  a  reasonable
interpretation  of  the regulation.[10]  However, the Secretary's
reliance upon other aspects  of  the  Dictionary's definitions of
the  term "level" as including "[a]ll openings  at  each  of  the
different  horizons  from  which  the  ore  body is opened up and
mining  is  started"  is  also  reasonable.   The  undercuts  can
certainly be found to reasonably meet the functional  aspects  of
the  definitions  of  the  term "level" because they are passages
driven along an essentially  level course affording access to the
workings  and  providing  ventilation  and  haulageways  for  the
removal  of  ore.  The Secretary's  interpretation  of  the  term
"lowest levels"  as  not being strictly related to elevation, but
more of a relative concept  with respect to other levels, is also
reasonable.  The ore body being mined here was irregular, both in
thickness  and  in elevation.   It  also  had  a  general  slope,
downward from north  to  south.   The  floors of the undercuts at
issue here were not the lowest points in the working areas of the
mines.  Depending upon the layout and topography  of a particular
mine, interpreting the term "lowest levels" as referring  only to
the  level,  a  portion  of  which  happened  to be the lowest in
elevation,  could  completely eviscerate the standard.   Although
the parties do not address  it, the use of the plural rather than
the singular form of the word level, lends further support to the
Secretary's interpretation of  the  standard  as applied here and
undercuts Doe Run's elevation argument.

     There   is   little   question   but  that  the  Secretary's
interpretation  of  the regulation is more  consistent  with  the
safety promoting purposes  of  the  Act.   Requiring two separate
escapeways  from  these  undercuts would enhance  the  safety  of
miners working in those areas,  though the degree to which safety
would  be enhanced is unclear because  of  the  limited  evidence
presented  on the actual hazards experienced in these mines.  Doe
Run  argues that  any  safety  enhancement  attributable  to  the
application of the Secretary's interpretation would be outweighed
by the  safety risks described with respect to the earlier mining
method.   That  argument  misses the mark.  It is highly unlikely
that enforcement of the Secretary's  interpretation  would prompt
an  operator  to  use  the  previous  method.  In many instances,
compliance  could  be  achieved by cutting  ventilation/escapeway
shafts through the relatively thin sills.  An operator might also
continue to use multiple  pass  mining,  driving  the  production
drift  into  the lower elevation of an ore body and mine the  ore
above by using  an  overcut,  or  a series of overcuts.  As noted
above,  the  Secretary  has at least tacitly  conceded  that  the
standard cannot reasonably be interpreted to apply to overcuts.

     Doe Run also argues  that  the Secretary's interpretation is
not  entitled  to deference here because  it  was  "newly  minted
during this case,"  was not announced in any policy memorandum or
embodied  in any agency  document,  is  inconsistent  with  other
interpretations  and has not been consistently applied.  However,
interpretations first put forward in the course of administrative
litigation  are, nevertheless,  entitled  to  deference  if  they
"reflect the  agency's fair and considered judgment on the matter
in question."   Akzo  Nobel  Salt, Inc. v. FMSHRC, 212 F.3d 1301,
1304 (D.C.Cir. 2000) (quoting  Auer v. Robbins, 519 U.S. 452, 462
(1997)) and cases cited therein.

     The interpretation advanced  here  appears  to  reflect  the
agency's  fair and considered judgment on the matter in question.
The testimony  of the Secretary's witnesses described the process
by which the enforcement  action  proceeded  to  this point.  The
original interpretation was applied to all single  access  areas,
and  used  wording  ("from that work area") inconsistent with the
applicable  standard.    For   this   administrative  litigation,
however,  that  position  was  reexamined in  meetings  involving
MSHA's administrators and members of the Office of the Solicitor.
The result was formulation of an  agency  interpretation, acceded
to  by  the  administrators  who  had  developed   the   original
interpretation.[11]  That interpretation was consistently applied
to  the  Secretary's  enforcement  action  and  thirteen  of  the
seventeen citations were vacated.

     The  interpretation  relied on here is not a rationalization
developed   on   appeal  after  administrative   litigation   had
concluded.  Contrary  to  Doe  Run's  argument, I do not find the
Secretary's   interpretation  substantively   inconsistent   with
interpretations  urged  by  the  Secretary in other cases.  It is
also not inconsistent with any other  agency  regulations, policy
directives   or   other  written  materials.   While  there   was
conflicting evidence as to whether single access areas existed in
other mines, some of  which  appear to be located within the same
MSHA district as Doe Run's mines,  this  appears  to be the first
instance  in  which  the  Secretary  has  determined  to initiate
enforcement action with respect to single access undercuts.

     Under  the  circumstances  presented  here,  the Secretary's
interpretation  is entitled to deference and Doe Run's  arguments
to the contrary are  rejected.   See National Wildlife Federation
v. Browner, 127 F.3rd 1126, 1129-30 (D.C.Cir. 1997).[12]  Doe Run
also  contends that the considerations  discussed  above  dictate
that the Secretary's interpretation is entitled to less deference
than a  more  established  or publicly promulgated pronouncement.
See A & W Smelter and Refiners,  Inc.  v. Clinton, 146 F.3rd 1107
(9th  Cir.  1998).   While  I  disagree,  even  under  a  reduced
deference    standard    I    would   sustain   the   Secretary's
interpretation.

Due Process -- Fair Notice

          Where  an  agency imposes  a  fine  based  on  its
     interpretation, a separate inquiry may arise concerning
     whether the respondent  has  received  "fair notice" of
     the interpretation it was fined for violating.   Energy
     West Mining Co.,
     17  FMSHRC 1313, 1317-18 (August 1995).  "[D]ue process
     . . .  prevents  .  .  .  deference from validating the
     application of a regulation  that  fails  to  give fair
     warning  of  the  conduct  it  prohibits  or requires."
     Gates & Fox Co. v. OSHRC,
     790   F.2d  154,  156  (D.C.Cir.  1986).   An  agency's
     interpretation  may  be  "permissible" but nevertheless
     fail  to  provide  the  notice   required   under  this
     principle  of  administrative law to support imposition
     of a civil sanction.   General  Electric,  53  F.3d  at
     1333-34.   The  Commission  has  not  required that the
     operator  receive  actual  notice  of  the  Secretary's
     interpretation.    Instead,  the  Commission  uses   an
     objective test, i.e.,  "whether  a  reasonably  prudent
     person  familiar  with  the  mining  industry  and  the
     protective   purposes   of   the  standard  would  have
     recognized the specific prohibition  or  requirement of
     the standard."  Ideal Cement Co., 12 FMSHRC  2409, 2416
     (November 1990).

Island Creek Coal Co., supra, 20 FMSHRC at 24.

     The issues raised by Doe Run on deference have  considerably
more force in its due process argument.  Doe Run's interpretation
of  the  standard  as  applied to these undercuts is at least  as
reasonable as the Secretary's.   Doe  Run had used this method of
mining for several years and its interpretation  of  the standard
had  never  been  called  into  question by the Secretary's  MSHA
inspectors.  Doe Run was aware of  other mines that had used this
method,  also  with  the  apparent  acquiescence  of  MSHA.   The
Secretary's formulation of her interpretation  included  at least
two  prior  iterations  and  was  ultimately developed during the
course of these proceedings.  I have no trouble concluding that a
reasonably prudent person familiar  with  the mining industry and
the protective purposes of the Act would not  have recognized the
specific prohibition of the

     [10]:   Doe   Run's   argument   that  a  "level"  must   be
independently connected to a shaft, is  unpersuasive.   It  would
appear  that all mines have at least one level, including, "adit"
mines, which  are  accessed  through  a  tunnel  and  do not have
shafts.  See Savage Zinc Co., supra.

     [11]:  Doyle  D.  Fink,  manager  of  MSHA's  South  Central
District,  in  which these mines were located, testified that  in
his opinion the  same safety considerations applied to all single
access areas and that  there  should  be two escapeways from such
areas.  He acknowledged, however, that  the standard treated such
areas differently and under the interpretation  advanced  by  the
Secretary  it could be applied only to the undercut areas.

     [12]:  While  the  Secretary's interpretation is entitled to
deference, considerations of due process preclude its application
here.   It  is,  therefore,  unnecessary  to  address  Doe  Run's
contention that the  area 1 pillar undercut at the Buick Mine was
an area of development,  for  which the standard does not require
two escapeways.
regulation  embodied  in the Secretary's  interpretation  of  the
standard  as  applied  to   these   undercuts.   The  Secretary's
determination not to respond to Doe Run's  due  process  argument
may  well  have  been  prompted by the weight of the evidence  in
support of its argument.

     Principles  of  due  process  preclude  application  of  the
Secretary's interpretation to these undercuts.

                              Order

     The  two  escapeway  standard,   as   applied  to  the  four
"undercuts"  at  issue  here,  is  ambiguous.   The   Secretary's
interpretation  of the standard, advanced for the first  time  in
this litigation,  reflects  the agency's considered judgement, is
reasonable and consistent with the protective purposes of the Act
and is entitled to deference.   Because Doe Run did not have fair
warning of the Secretary's interpretation,  however, it cannot be
enforced in these instances.[13]

     [13]:  There  is  little question but  that  all  of  the
working areas accessible only  by  a  single drift present safety
concerns.  The Secretary's interpretation  of  the  two escapeway
standard  permitted her to address only 4 of the 17 cited  areas.
The precise  degree  of  risk presented, however, remains largely
unquantified.  Formal rulemaking would appear to be the preferred
approach to address those concerns.
