ILLINOIS POLLUTION CONTROL BOARD
March 28,
 1991
IN THE MATTER OF:
 )
RACT DEFICIENCIES IN THE
METRO-EAST AREA:
 AMENDMENTS
 )
 R91-8
TO 35 ILL.ADM.CODE PART 215
 )
 (Rulemaking)
AND THE ADDITION OF PART 219
ORDER OF THE BOARD
 (by J. Theodore Meyer):
On
 January
 17,
 1991,
 the Illinois Environmental Protection
Agency
 (Agency)
 filed this proposal for rulemaking.
 The proposal
seeks
 to
 correct
 deficiencies
 identified
 by
 the United
 States
Environmental Protection Agency in Illinois’ state implementation
plan
 (SIP)
 for
 ozone
 for
 the
 Metro—East
 area,
 and
 contains
regulations requiring the implementation
 of
 reasonably
 available
control technology
 (RACT)
 for certain sources of volatile organic
material
 (VOM).
 The proposal was accepted for hearing on February
7,
 1991.
 The Board, without taking a substantive position on the
proposal,
 sent the proposal to first notice on February 28,
 1991.
This
 proposal
 has
 been
 certified
 by
 the
 Agency
 to
 be
 a
“required rule”,
 as provided in Section 28.2 of the Environmental
Protection Act (Act)
 (Ill.Rev.Stat. 1989,
 ch. 111 1/2, par. 1028.2,
as amended by P.A.
 86-1409,
 effective January
 1,
 1991),
 and the
Board has accepted that certification.
 Section 28.2(c)
 requires
that the Board determine whether an economic impact study
 (EcIS)
should be prepared on the proposal.
 In making this determination,
the Board is to consider the potential economic impact of the rule,
the potential for consideration of the economic impact without
 an
EcIS,
 the
 extent,
 if
 any,
 to
 which
 the
 Board
 may
 modify
 the
substance of the rule based upon the conclusions of
 a study,
 and
statutory deadlines for promulgation
 of the rule.
 (Section 28.2
and 35 Iil.Adm.Code 102.182.)
In
 its
 proposal,
 the
 Agency
 asked
 that
 an
 EcIS
 not
 be
prepared.
 The Agency states that the proposed rules are identical
in effect to rules already in effect at the federal level for the
Chicago area, and that these rules represent RACT in Illinois.
 The
Agency
 maintains that the Clean Air Act and the 1990 amendments
require Illinois to adopt approvable RACT requirements, and that
 USEPA will adopt RACT rules if Illinois does not.
 The Agency also
points out that its proposal contains documentation describing the
Agency’s investigation into the economic impact of these proposed
rules,
 and
 contends
 that
 no
 further
 economic
 impact
 study
 is
necessary.
 The Department
 of
 Energy and Natural Resources
 (ENR)
did not file a recommendation.
The Board
 agrees
 with
 the Agency
 that
 no
 EcIS
 should
 be
120—471
2
prepared in this proceeding.
 The Board believes that the question
of
 economic
 impact
 can
 be
 adequately
 explored
 in
 the
 hearing
process
 and through written comments.
 Additionally,
 given the
tight time frames in this rulemaking,
 the Board
 finds that it
 is
not appropriate to request an EcIS.
 The Board will,
 of course,
consider
 the
 economic
 impact
 of
 this
 proposal
 to
 the
 extent
possible, consistent with Section 28.2(b).
 (See Section28.2(d).,)
Finally,
 on March
 18,
 1991,
 the Agency
 filed
 a motion
 to
correct the proposal and response
 to Board order
 regarding the
incorporations
 by
 reference.
 The Agency
 seeks
 to
 delete
 the
reference in the table of contents to sections 219.127 and 219.128.
Those references were included inadvertently, and there is no text
corresponding to those section numbers.
 Additionally, the Agency
asks to substitute corrected exhibits
 5,
 8,
 14, -and 17 for those
exhibits submitted with the proposal.
 The Aqency states that
 it
has made a number of changes which will make the documents,
 which
are
 testimony
 in
 support
 of
 the
 proposal,
 clearer
 and
 more
accurate.
 The Agency also asks the Board to accept Attachment A
as
 its
 response
 to
 the
 Board’s
 February
 7
 order
 regarding
incorporations by reference.
 The Agency’s motions are granted.
The Board
 specifically points
 out to all participants
 that the
substituted
 exhibits
 contain
 testimony
 for
 the April
 15.
 1991
hearing in this proceeding.
IT IS SO~ORDERED.
I,
 Dorothy M.
 Gunn,
 Clerk
 of the Illinois Pollution Control
Board
 hereby

 the above
 Order
 was adopted
 on
 the
______
 day of
