PROPOSED

 SECOND NOTICE
PROPOSED OPINION AND ORDER OF THE BOARD
 (by J.
 D.
 Durnelle):
On
 July
 19, 1984, the Board adopted a Proposed Rule/First
Notice Proposed Opinion and Order which was published in the
Illinois
 Register
 on August 24, 1984, at 8
 Iii,
 Reg.
 15561.
 Four
comments were filed during the first notice period which closed
on October
 10, 1984.
 Public Comment No,
 18 was filed on October
4,
 1984, on behalf of the Illinois Power Company (IPC).
 Public
Comments
 Nos.
 19 and 20 were filed on October 19,
 1984, on behalf
of the Illinois Environmental Protectin Agency (Agency) and A.
 E.
Staley Manufacturing Company (Staley), respectively.
 Public
Comment No.
 21 was filed by Bud Meyer of the DuPage Health Department.
Staley supports the rules as proposed for first notice, but
also states that ~‘theBoard should allow existing sources a
specified amount of time after promulgation of the proposed rules
to attain compliance.”
 It recommends a 12—18 month period.
Bud Meyer states that the amendment of 35
 Iii. Adm. Code
212.203 is confusing and could be more clearly worded.
The Agency supports the adoption of 35
 Ill. Mm. Code 212.123
which establishes opacity limits.
 However,
 it disagrees with the
Board’s failure to include a second significant decimal
 figure in
35 Ill. Mm. Code 212.201.
 It also strongly opposes the modification
to the introductory paragraph of 35
 Ill. Mm. Code 212.203 which
changes the numerical limit from 0.2 lbs/MBtu to 0.25 lbs/MBtu
and criticizes the paragraph added to that section.
IPC also disagrees with the proposed amendments to Section
212.203 and states that the Board erred in rejecting IPC’s request
for a mechanism allowing site—specific relief to be granted
 in an
adjudicatory proceeding.
Since no one has commented adversely upon 35
 Ill. Mm. Code
212.123,
 212.202 or 212.204, the Board proposes to adopt these
sections for second notice in the same form as they were proposed
for first notice with only very minor, non—substantive,
 language
changes to clarify those rules.
 Each of the other sections will
he more fully addressed.
61-369

Section 212.201
The Agency has requested that the Board amend the 0.1
 lbs/MBtu/hr standard of Section 212.201 to 0.10 lbs/MBtu/hr.
 It
points out that this is the number of significant digits used in
the air quality modeling which supports the standard
 arid that the
amendment is consistent with the Agency’s historical application
of these
 rules both in terms of permitting and the State Imple-
mentation Plan.
 The Board finds the Agency’s argument persuasive
and will
 so amend the section.
 The Board notes, however,
 that by
so amending this standard, it does not intend to imply that the
standard as originally adopted was intended
 bo mean anything
other than 0.10 lbs/MBtu/hr.
Section 212.203
The amendments to 35
 Ill. Adm, Code 212.203 have generated
the bulk of the comments.
 This section
 is
 in essence a partial
grandfather clause which was intended to equitably treat those
sources for which substantial expenditures were made prior to
adoption of the original rule which resulted
 in near compliance.
The original rule allowed certain sources which emitted between
0.1 to 0.2 lbs/MBtu/hr to continue in operation so long as their
emissions did not increase by more than 0.05 lbs/MBtu/hr from
their base emissions and
 so long as the emissions did not surpass
the 0.2 pound
 limit,
In the first notice order the Board made two modifications
to this section.
 The first allowed the grandfathered sources to
emit up to a maximum of 0.25 lbs/MBtu/hr.
 This was done to
remove any ambiguity with respect to
 a source with a base emission
of between 0.15 and 0.20.
 Of course,
 the possible ambiguity
could have also been resolved by setting the limitation at 0.20
lbs.
 The Board found that the former action was more in accordance
with the orignal intent of the rule.
 The Agency, however, dis-
agrees, commenting that the rule
 is unambiguous and that the 0.20
standard has been “applied by the Agency for purposes of issuing
permits and for developing the State Implementation Plan.”
 (See
P.C.
 No.
 19,
 p.
 3, and 5/26/82,
 R.
 165),
 IPC does not appear to
disagree.
 Further,
 the Agency points out that there are at least
two sources in non—attainment areas whose allowable emissions
could increase if the Board were to finally adopt this modifi—
cation and that the potential impact has not been assessed in the
record.
 Finally, the only participant who argued that the 0.25
limit was the appropriate one was the Village of Winnetka,
 and,
as more fully discussed below, the Village will be exempted from
the application of this rule pending a site—specific determination.
The Board is persuaded by the Agency’s
 comments
 and a review
of the record that a 0.25 standard has not been adequately supported
in the record and the Board will, therefore, propose the 0.20
lbs/MBtu/hr standard for second notice,
61-370
3
The
 second
 modification
 of
 this
 section
 was proposed to
minimize,
 so far as the record supported
 it, the impact of changes
in the test methods for the
 determination
 of particulate emissions
between 1972 and the present.
 The Board attempted to make the
rule more flexible by allowing the use of original design speci-
fications at full
 load in lieu of performance tests
 at part load
(to simplify the rather complex provision).
 The Agency has
commented
 that “the effect is to further complicate a complicated
rule”
 (PC
 No.
 19,
 p.
 4).
 IPC
 contends
 that the
 modification
addresses “only one limited aspect of the multifaceted problem of
changing test conditions and testing methodologies”
 and
 “is
 so
ambiguous that it may be unenforceable”
 (PC No.
 18,
 p.
 6).
 Bud
Meyer finds
 the proposed modification confusing.
 Of the commenters
only Staley supports this modification.
The Board was aware at the time it proposed this modification
that it was not
 a complete answer to the problem of
 the
 changing
test
 methods used to determine degradation.
 However,
 in
 the
Board’s first notice opinion, the Board
found
 the
 original rule
to
 be
 unfair in light
 of
 the
 changed test methods and found IPC’s
proposal to rectify the problem overly vague.
 Therefore, the
Board modified IPC’s proposal
 in the only more defined manner for
which it could find adequate support in the record,
 However,
based upon the comments and a review of the record, the Board
finds
 its first notice modification unsatisfactory.
The Board continues to
 find
 that the changes
 in test methods
have rendered the degradation provision troublesome at best:
i.e.,
 to
 continue the original provision
would
 be unfair to
affected facilities,
 and
 the
 record
 fails to support a modification
of that provision which would remedy that unfairness.
 Further,
the originally proposed rule,
 the Board’s first notice proposal,
and IPC’s pre—first notice proposal
 leave much to be desired
 in
terms of clarity and enforceability.
 The Board, therefore,
proposes to delete that provision and instead to propose the
amendment
 of Section 212.203 in substantial conformance with
 IPC’s
 proposal
 presented
 in
 its
 public
 comment
 (PC
 No,
 18,
 p.
12), except that it shall apply only to those facilities which
are located in attainment areas.
In P.C. No,
 18 IPC proposed a revision to Section 212.203
which it contends would satisfy both the Board’s and its concerns.
That provision would allow all eligible sources to emit up to
0.20 lbs/MBtu/hr,
 To qualify,
 such source would have had to
achieve emissions of less than that amount based on the emission
test performed closest to April
 14, 1972 or would have had to be
in compliance with a variance as of that date sufficient to achieve
that emission rate.
 In short,
 IPC proposes to retain the original
rule without a degradation provision.
IPC had earlier proposed a similar provision to which the
Agency objected.
 (See Agency Comment, December 20,
 1983,
 pp.
16-21).
 The Agency contends that “the factual evidence provided
by Illinois Power does not support the conclusion that the dif-
ferences in the tests are resulting in emissions which would
jeopardize
 a sOurce’s qualifying for an emission limit” under the
61-371
4
original rule (ibid,
 p.
 16).
 However, to contend that a provision
should be retained which has been found to be unfair simply
 because it has not yet resulted in any unfairness ignores potentially
affected facilities.
The Agency also “finds the record insufficient to conclude
that adoption of the change would not jeopardize air quality on a
state—wide basis”
 (ibid, pp. 18—19). The Agency does,
 however,
admit that the “air quality demonstration performed by IPC...
may indicate that isolated sources
 in rural
 areas could increase
emissions by 0.1 lb/mBtu without significantly impacting air
quality” and its real concern appears to be that “an increase in
allowable emissions for sources in non—attainment areas must be
scrutinized”
 (ibid, p.
 20).
 The Agency further contends that
such increases have not been addressed on the record,
 and while
IPC did present a modeling study of its Wood River plant in the
East St. Louis Major Metropolitan Area, the Agency’s contention
is for the most part correct.
The Board finds that the record includes adequate support
for allowing eligible sources to emit up to 0,20 lbs/MBtu/hr in
attainment areas but insufficient support for such sources
 in non—
attainment areas.
 Therefore, the Board proposes to allow eligible
sources
 in attainment areas to emit up to that amount,
 However,
the Board notes that this modification cannot be used to allow
unreasonable degradation.
 The Board expects that all sources
will do their best to adequately maintain their equipment and
 notes further that the Agency has the power to require adequate
maintenance as
 a permit condition pursuant to 35
 Ill. Mm. Code
201.156 and 201.161.
A separate docket will be opened in this proceeding which
may be utilized to establish site—specific standards for those
facilities in nonattainment areas which would have qualified for
a limitation of greater than 0.10 lbs/MBtu/hr under the original
proposal.
 Such facilities would be required to file a site—specific
proposal within
 3 months of the filing of these rules and to
proceed to hearing within
 3 months thereafter.
 The facilities
would be required to demonstrate that they meet the requirements
of the class and that emissions at the proposed level would not
jeopardize attainment of the National Ambient Air Quality Standards,
the Act,
 or Board rules.
 They would further be required to
assess the adverse environmental
 impact of emitting greater than
0.10 lbs/MBtu/hr and the economic cost increase of meeting the
otherwise applicable standard.
Site—Specific Relief
The Board had hoped to avoid opening another docket within
this proceeding.
 However, the comments have made it clear that
there simply is not sufficient evidence
 in the record to support
any general rule regarding sources which would qualify for a
relaxed emission limitation pursuant to Section 212.203 but for
being in a nonattainment area.

The
 Board
 anticipates
 that
 the
 economic
 impact
 study
 prepared
by
 the
 Department
 of
 Energy
 and
 Natural
 Resources
 and
 the
 hearings
held regarding it will be sufficient
 to
 satisfy
 those requirements
of
 Section
 27
 of
 the
 Illinois
 Environmental
 Protection
 Act
 (Act)
and
 that this docket may proceed on an expedited basis.
The Village of Winnetka has attempted to substantiate site—
specific particulate limitations for its power plant during the
course of this proceeding.
 The Board, however, has attempted to
establish
 a
 rule
 of
 general
 applicability.
 The Board now proposes
such a rule. However, the Board has also opened a new docket,
R82—l, docket A for the purpose of establishing site-specific
limitations
 for those facilities which
 are
 not
 covered
 by
 the
general rule.
 Since such a docket has been established, the
Village of Winnetka will be allowed to seek such site—specific
relief under new Section 212.209.
The Board will not establish any adjudicatory procedure for
other facilities as again urged by IPC and
 has
 not
 changed
 its
reasons for denying that request.
 The first notice proposed
opinion relied on the anticipated enactment
 of
 SB 1862 which,
 in
fact, became effective on September
 9,
 1984,
 as
 Public Act 83—1355.
Such reliance is, therefore,
 no longer misplaced.
 Further,
 IPC
has now commented upon the Board’s interpretation of
 that
 statute
and the Board is under no obligation to provide notice as to what
special circumstances must be shown to be entitled to such relief.
It is sufficient to note that there must be some special circum-
stances shown or most of Section
 27 of the Act would become
rieaningless.
Effective Date
Staley commented
 (P.C.
 No,
 20)
 that the Board should include
an effective date for these rules to allow “existing sources a
specified amount of time after promulgation
 of
 the proposed rules
to attain compliance.”
 It suggests 12—18 months after promulgation.
While
 most
 sources
 are
 in
 present compliance,
 and the Board
expects
 those
 sources
 to
 remain
 in
 compliance,
 there
 may
 well
 be
sources which are not and cannot immediately come into compliance.
Therefore,
 since these rules are, at least
 in theory, new rules,
the
 Board
 will
 add
 new
 Section
 212.210
 to
 establish
 an effective
date
 of
 January
 1,
 1987.
Extension of Comment Period
The rules that the Board today proposes for second notice
differ from those proposed for first notice.
 While the Board does
not
 feel
 that
 these
 changes
 are
 so
 substantial,
 or
 involve
 such
different issues,
 that it is necessary to return to first notice,
the Board will not file its second notice until
 at least 35 days
after adoption of this opinion and order.
 During that period of
time, the Board will accept comments on this second notice proposal.
The Board notes, however, that it
 is not interested
 in the reiteration
of previously filed
 comments,
 but rather is interested in comments
on the proposed changes from first notice.
61-373

British Thermal Units
The Board’s abbreviation of British Thermal units stated in
 35
 111. Adm. Code 201.103 is at odds with most other authocities
and has been used somewhat inconsistently as
 is its abbreviation
for million British thermal units.
 Therefore, the Board will
amend that section to accommodate “MBtu,”
 “mmBtu,”
 “Mbtu” and
“mmbtu.”
 When the Board completes
 its updating of the air po1—
lution rules under docket R79—l4, the abbreviations can be made
consistent.
