Adopted Rule. Final Notice.
 
OPINION AND ORDER OF THE BOARD (by T.E. Johnson):
 
On November 19, 2004, the Illinois Environmental Protection Agency (Agency) filed a
proposal for rulemaking pursuant to Sections 9.8, 27 and 28 of the Environmental Protection Act
(Act). 415 ILCS 5/9.8, 27 and 28 (2002). The Agency proposes to amend the Board’s air rules,
specifically the rules relating to Emissions Reduction Market System (ERMS). The Agency’s
proposal is intended to ensure the continued maintenance of the Volatile Organic Material
(VOM) reductions in the Chicago nonattainment area with the revocation of the 1-hour ozone
standard and implementation of the new 8-hour ozone. The Board sent the proposal to first
notice on December 2, 2005, without commenting on the
 
By today’s action the Board adopts the proposed rule. The rules adopted here are
substantively unchanged from those adopted in the Board’s first-notice and second-notice
opinion and orders. On April 21, 2005, the Board adopted the rule for second notice. The Board
directed that the rule be submitted to the Joint Committee on Administrative Rules (JCAR) for
ackground, summarize the procedural history,
nd technical feasibility of the rule.
BACKGROUND
 
Part 205, ERMS, was adopted by the Board on November 20, 1997, and received
approval by the United States Environmental Protection Agency (USEPA) as part of the Illinois
State Implementation Plan (SIP) for ozone, effective November 14, 2001. Agency Stat. of Reas.
at 1. The ERMS system is a cap and trade program that involves VOM emissions in the Chicago
ozone nonattainment area (Chicago area).
Id
. It is designed to reduce VOM emission in the
Chicago area below the levels required by reasonably available control technology and other
emission standards.
Id
. The ERMS applies to certain participating sources located in the
Chicago area that are currently required to obtain Clean Air Act Permit Program (CAAPP)
permits and have seasonal emissions of at least 10 tons of VOM in a seasonal allotment period,
which is the period from May 1 through September 30 of each year. Agency Stat. of Reas. at 1-
2. The Agency is proposing revisions to the program rules affecting sources in the Chicago area.
 

 
 
2
The Agency asserts that revisions are needed because the USEPA is revoking the 1-hour
ozone national ambient air quality standard (NAAQS) effective on June 15, 2005, as a part of the
implementation process of the new 8-hour ozone NAAQS. Agency Stat. of Reas. at 2. The
Agency notes that upon the revocation of the 1-hour ozone NAAQS, the Chicago area will be
classified as a moderate nonattainment area for the 8-hour NAAQS.
Id
. The Agency contends
that the redesignation of the Chicago area as “moderate” under the 8-hour ozone NAAQS affects
applicability thresholds for major sources, which are regulated under Illinois’ CAAPP - currently
major sources subject to the CAAPP are those with potential to emit 25 tons or more of VOM
per year, but once the 1-hour ozone NAAQS is revoked, the applicability threshold raises to 100
tons or more per year of VOM under the new 8-hour ozone NAAQS. Agency Stat. of Reas. at 2-
3.
 
Since ERMS applies to certain sources that are required to obtain CAAPP permits, the
Agency asserts that the change in CAAPP threshold will result in less facilities being subject to
the rules and a corresponding loss of approximately 330 tons of VOM emissions reductions for
each seasonal allotment period. Agency Stat. of Reas. at 3. The Agency asserts that it must
ensure that ERMS remains in place in its current form so the required VOM emissions
reductions in the Chicago area is maintained. Agency Stat. of Reas. at 4.
 
PROCEDURAL HISTORY
 
On November 19, 2004, the Agency filed a petition, accompanied by a motion for
expedited consideration. On December 2, 2004, the Board opened regulatory docket R05-11
without commenting on the merits of the proposal. The Board also granted the motion for
expedited review.
 
Hearings in this matter were held on January 27, 2005 and February 22, 2005, both at 100
West Randolph Street, Chicago, Cook County. The Agency appeared and presented testimony at
the hearing. A representative from the Illinois Environmental Regulatory Group (IERG) was
present at the first hearing. No members of the public attended either hearing. No public
comments were filed after either hearing. The February 22, 2005 hearing was held, in part, on
the requested economic impact study of this rulemaking, in order to fulfill the requirements of
Section 27(b) of the Act. 415 ILCS 5/27(b) (2002). Section 27(b) of the Act requires the Board
to request the Illinois Department of Commerce and Economic Opportunity (DCEO) to conduct
an economic impact study (EcIS) on certain proposed rules prior to adoption of those rules.
 
On December 9, 2004, the Board sent a letter to DCEO requesting a study for this
rulemaking. On January 20, 2005, the Board received a response from DCEO indicating that it
would not perform an economic impact study on this rule. Copies of the letters were available
at both hearings, and in the Board’s Chicago office. The Board received no comments on the
letters.
 
In its second-notice opinion and order issued on April 21, 2005, the Board found that
adoption of the Agency’s proposed rule was warranted, and proposed the rulemaking for second-
notice review by the JCAR.
 

 
 
3
JCAR considered the second-notice proposal at its May 17, 2005 meeting and determined
that no objection would be made. JCAR suggested four non-substantive changes, and issued a
formal certification of no objection to the proposed rulemaking dated May 17, 2005.
 
The second-notice period commenced on April 28, 2005, and ended on May 17, 2005,
when the Board received notification from JCAR that no objection will be issued.
See
5 ILCS
100/5-40(c) (2002); 35 Ill. Adm. Code 102.606. Other than the non-substantive comments
suggested by JCAR, the Board received no comments during the second-notice period.
 
DISCUSSION
 
At first notice, the Board adopted the proposed rule for first notice, but did not make any
decisions regarding the proposal itself. At second notice, the Board found that adoption of the
proposal is warranted to ensure the maintenance of the VOM reductions in the Chicago area.
The Board found that the proposal was economically reasonable and technically feasible. More
specifically, the Board agreed with the Agency that the proposal does not raise any questions
regarding technical feasibility or economic reasonableness since the proposed amendments do
not impose any new emission limitations or require new control devices on affected sources.
The Board noted that, based on an extensive record in Docket 97-13, it has already found that the
ERMS in its present form is technically feasible and economically reasonable. To date, the
Board has received no additional comments discussing economic reasonableness and technical
feasibility of the proposed rule.
 
As discussed in the second-notice order, the Board requested that DCEO conduct an
economic impact study for this rulemaking. On January 20, 2005, the Board received a response
from DCEO indicating that it would not perform an economic impact study on this rule. Copies
of the letters were available at both hearings, and in the Board’s Chicago Office. The Board
received no comments on the letters.
 
As noted, the Board did receive four non-substantive comments from JCAR. The Board
has incorporated the suggested changes into the adopted proposal.
 
CONCLUSION
 
 
  
Based on the record before it, the Board finds that adoption of the Agency’s proposal is
warranted.
 
ORDER
 
The Board directs the Clerk to file the following adopted rule with the Secretary of State
for publication in the
Illinois Register
for final notice and adoption in the
Illinois Administrative
Code

Section 205.318
Certification for Exempt CAAPP Sources
 
The owner or operator of any source that is located in the Chicago ozone nonattainment area that
is required to obtain a CAAPP permit, and has seasonal emissions, as determined in accordance
with Section 205.320(a) of this Subpart, of less than 10 tons shall submit a written certification to
the Agency by March 1, 1998, certifying that its VOM emissions are below 10 tons per season as
specified in Section 205.320(a) of this Subpart. Such certification shall include the amount of
VOM emissions at the source during the 1994, 1995, 1996 and 1997 seasonal allotment periods,
and supporting calculations.
 
(Source: Amended at __ Ill. Reg. _____, effective ______________)
 
Section 205.320 Baseline Emissions
 
a) Except as provided in subsection (b) or (c) of this Section, baseline emissions
shall be determined by the Agency in accordance with the following, adjusted as
specified in subsections (d), (e) and (f) of this Section:
 
1) Baseline emissions shall be calculated using the average of the two
seasonal allotment periods with the highest VOM emissions during 1994,
1995 or 1996.
 

 
21
2) Any source may propose to substitute seasonal emissions on a year-for-
year basis due to non-representative conditions in 1994, 1995 or 1996, but
must stay within the period from 1990 through 1997, and must have
accurate seasonal emissions data for the substitute year(s). When
considering whether to substitute a seasonal baseline emission year(s), the
Agency must consider the information submitted by the source pursuant to
Section 205.310(b)(1)(B) of this Subpart, as well as the accuracy of that
data. For the purposes of this subsection (a)(2), “non-representative
conditions” include, but are not limited to, events such as strikes, fires,
floods and market conditions.
 
b)
Except as provided below in subsection (c) of this Section, for For any source that
has seasonal emissions of less than 10 tons, as determined in accordance with
subsection (a) of this Section, but becomes a participating source because its
seasonal emissions increase to 10 tons or more in any seasonal allotment period
beginning with 1999, baseline emissions shall be determined by the Agency based
on actual VOM emissions from the first seasonal allotment period in which the
source’s sources emissions equaled or exceeded 10 tons, adjusted as specified in
subsections (d), (e) and (f) of this Section, provided such emissions increase is not
a major modification pursuant to 35 Ill. Adm. Code 203.
 
c) For any source that has seasonal emissions of less than 10 tons, as determined in
accordance with subsection (a) of this Section, but becomes a participating source
because its seasonal emissions increase to 10 tons or more in any seasonal
allotment period beginning with 1999 and this emissions increase constitutes a
major modification pursuant to 35 Ill. Adm. Code 203, baseline emissions shall be
determined by the Agency based on the average of the actual seasonal emissions
from the two seasonal periods prior to a timely submittal of its application for the
major modification, adjusted as specified in subsections (d) and (e) of this
Section. Any such source may substitute seasonal emissions on a year-for-year
basis due to non-representative conditions in either of the two seasonal allotment
periods prior to submittal of its application for the major modification but must
stay within the five year period prior to submittal of such application. For the
purposes of this subsection, “non-representative conditions” include, but are not
limited to, conditions such as strikes, fires, floods and market conditions.
 
d) The baseline emissions of any participating source shall be increased for
voluntary over-compliance that occurred after October 31, 1990 and results in a
VOM emissions level that is lower than the level required by applicable
requirements effective in 1996, including limitations in the source’s permit(s)
based on such applicable requirements. Voluntary over-compliance shall be
determined in accordance with the following:
 
1) Determine the actual activity or production types and levels from the
seasonal allotment period(s) selected for baseline emissions pursuant to
subsection (a), (b) or (c) of this Section;

 
22
 
2) Determine seasonal emissions for each emission unit as the product of the
amount of activity or production, as determined in accordance with
subsection (d)(1) of this Section, and the actual emissions level;
 
3) Determine seasonal emissions for each emission unit as the product of the
amount of activity or production, as determined in accordance with
subsection (d)(1) of this Section, and the allowable emissions level
pursuant to all applicable requirements effective through 1996, including
limitations in the source’s permit(s) based on such applicable
requirements; and
 
4) Determine the appropriate adjustment to baseline emissions by subtracting
the seasonal emissions determined pursuant to subsection (d)(2) of this
Section from the seasonal emissions determined pursuant to subsection
(d)(3) of this Section.
 
e) The baseline emissions of any participating source shall be decreased if any of the
following circumstances exist:
 
1) If a source is out of compliance with any applicable requirements,
including limitations in the source’s permit(s) based on such applicable
requirements, in any of the seasonal allotment periods used for baseline
emissions, its baseline emissions shall be lowered to reflect the amount of
VOM emissions that would be achieved if in compliance with such
requirements.
 
2) If any of the seasonal allotment periods selected for baseline emissions do
not reflect compliance with requirements effective through 1996 that
became applicable after any of the years selected as baseline years, the
source’s baseline emissions shall be lowered to reflect the amount of
VOM emissions that would be achieved if in compliance with such
requirements.
 
3) If, in any of the years selected for baseline emissions, a source’s VOM
emissions are in excess of the amount of VOM emissions allowed by
applicable rules because it has been granted a variance, has entered into a
consent order, or is operating pursuant to a CAAPP permit compliance
schedule, the baseline emissions for such source shall be lowered to reflect
the VOM emissions amount that would be achieved if in compliance with
such requirements, subject to the following:
 
A) Each such source shall be allowed to emit VOM emissions in
excess of the ATUs it holds at the end of the reconciliation period
each year until compliance with the applicable regulation is
achieved, or upon expiration of the relief allowed for in the

 
23
variance, consent order or CAAPP permit compliance schedule,
whichever occurs first;
 
B) Such excess VOM emissions shall be allowed to the extent allowed
in the variance, consent order or CAAPP permit compliance
schedule; and
 
C) The seasonal component of the Annual Emissions Report for each
such source shall be adjusted each year until compliance with the
applicable requirement(s) is achieved, or upon expiration of the
relief allowed for in the variance, consent order or CAAPP permit
compliance schedule, whichever occurs first, as specified in
subsection (e)(3)(B) of this Section.
 
4) For any participating source that operated with excess emissions during
startup, malfunction or breakdown during any year used to determine its
baseline emissions, whether or not such operation was authorized pursuant
to the source’s permit, excess VOM emissions attributable to startup,
malfunction or breakdown shall be excluded from the baseline emissions.
 
f) For new or modified emission units at a source for which a construction permit
was issued prior to January 1, 1998, but for which three years of operational data
is not available, the baseline emissions determination for the source shall include
VOM emissions from such new emission unit or the increase in emissions from
the modification of such emission unit based on the two seasonal allotment
periods with the highest VOM emissions from the first three complete seasonal
allotment periods in which any such new or modified emission unit is operational.
ATUs shall only be issued in accordance with this subsection after the baseline
emissions has been determined. Any such source shall not be required to hold
ATUs for VOM emissions attributable to the new emission unit or the
modification of the existing emission unit for the first three complete seasonal
allotment periods in which it is operational.
 
g) For any source which acquired emission reduction credits pursuant to a written
agreement, entered into prior to January 1, 1998, and such emission reduction
credits were acquired for use as emissions offsets, in accordance with 35 Ill. Adm.
Code 203, such emission reduction credits, adjusted for the seasonal allotment
period, and reduced by 24 percent, shall be included in the baseline emissions
determination for the source, only to the extent that:
 
1) The Agency has issued a federally enforceable permit, prior to January 1,
1998, to the source from which the emission reduction credits were
acquired, and such federally enforceable permit recognized the creation of
the VOM emission reduction credits by the cessation of all VOM-emitting
activities and the withdrawal of the operating permits for VOM-emitting
activities at such other sources; and

 
24
 
2) The Agency has not relied upon the emission reduction credits to
demonstrate attainment or reasonable further progress.

Section 205.330
Emissions Determination Methods
 
The owner or operator of a participating source or new participating source shall determine
VOM emissions from the source during the seasonal allotment period using methods as
necessary to demonstrate compliance with this Part. Such methods shall be, at a minimum, as
stringent as those required by any applicable requirement and any permit condition. The Agency
shall establish the emissions determination methods applicable to each such source in the
source’s CAAPP permit or FESOP. The following methods, in conjunction with relevant
source-specific throughput and operating data, are acceptable methods a source may use to
determine seasonal emissions, depending on the type of emission unit:
 
a) Material balance calculation, based on the VOM content of raw materials and
recovered materials, as is typically used for degreasers, coating lines, and printing
lines equipped with a carbon adsorption system (recovery-type control device) or
without any control device;
 
b) A standard engineering formula for estimation of emissions, as is typically used
for storage and transfer of volatile organic liquids;
 
c) A source-specific emission factor(s), based on representative testing and sampling
data and appropriate analysis, as typically used for petroleum refining processes;
 
d) A published USEPA emission factor(s), as is typically used for component leaks;
 
e) A source-specific emission rate or VOM control efficiency, based on
representative testing, as is typically used for chemical processes and afterburners
(destruction-type control device), respectively;
 
f) A method not listed above that is sufficient to demonstrate compliance with this
Section; or
 
g) An appropriate combination of the above methods, as typically used for a coating
or printing line equipped with a control device, where the available emissions are
determined by material balance and the control efficiency is determined by
representative testing.

Section 205.337 Changes in Emission Determination Methods and Sampling, Testing,
Monitoring and Recordkeeping Practices
 
a) The methods used for determining seasonal emissions from a source shall
generally be consistent with the methods used to determine its baseline emissions
unless the source's permit accommodates the use of alternate methods to
determine VOM emissions.
 
b) Modification of Methods and Practices
 
1) If a source proposes new or revised methods to determine VOM emissions
or new or revised supporting practices for sampling, testing, monitoring or
recordkeeping that differ significantly from the methods and practices
specified by its current permit, the source shall obtain a revised CAAPP
permit in accordance with the procedures specified in Section 39.5 of the
Act [415 ILCS 5/39.5], or a revised FESOP, prior to relying on such
methods and practices.
 
2) The Agency shall issue a revised permit if it finds, based upon submission
of an appropriate permit application, that the proposed methods or
practices are needed or appropriate to address changes in the operation of
the source or emission units that were not considered when the current
permit was issued, that the proposed methods and procedures will not
significantly affect the determination of actual seasonal emissions, or that
the proposed methods and procedures incorporate new or improved
analytical techniques or estimation methods that will increase the accuracy
with which actual seasonal emissions are determined, and other applicable
requirements for issuance of a revised permit are met.
 
3) If the Agency approves the use of a modified method or practice, the
Agency is authorized to determine a corrected baseline and thereafter issue
ATUs in accordance with Section 205.400(c) of this Part pursuant to this
corrected baseline.

b) Except for ATUs issued pursuant to Sections 205.500 and 205.510 of this Part,
ATUs issued for any seasonal allotment period are valid for use during the
seasonal allotment period following issuance and the next succeeding seasonal
allotment period. All ATUs shall be valid until such ATUs expire or are retired.
 
c) The initial allotment for each participating source shall be based on the baseline
emissions for such source, as determined in accordance with Section 205.320 of
this Part, and shall be reduced by 12 percent in 1999 or in such other year that a
source is issued its initial allotment, except as provided in Section 205.405 of this
Subpart.
 
d) Except as provided in Section 205.337(b)(3) of this Part and subsections (c) and
(e) of this Section, allotments shall remain at 1999 or initial levels unless the
Agency makes a demonstration to the Board, in accordance with the rulemaking
provisions of Sections 9.8, 27 and 28 of the Act [415 ILCS 5/9.8, 27 and 28], that
further reductions are needed. An allotment or a baseline under this Part does not
constitute a property right. Nothing in this Part shall be construed to limit the
authority of the Board to terminate or limit such allotment or baseline pursuant to
its rulemaking authority under Sections 9.8, 27 and 28 of the Act [415 ILCS 5/9.8,
27 and 28].
 
e) If the baseline emissions for any participating source are increased in accordance

for each seasonal allotment period in which it is operational.
 
g) Any source existing as of May 1, 1999, which first becomes subject to the
requirements of this Part because its seasonal emissions increase to 10 tons or
more as a result of a major modification pursuant to 35 Ill. Adm. Code 203, in any
seasonal allotment period beginning with 1999, shall not be allotted ATUs by the
Agency for the VOM emissions attributable to this modification, except as
provided in subsection (h) of this Section, but shall be allotted ATUs by the
Agency based on its baseline emissions, as determined in accordance with Section
205.320 of this Part. Any such participating source shall be required to hold

 
 
27
ATUs at the end of the reconciliation period as specified in Section 205.150(c) of
this Part, for each seasonal allotment period in which it is subject to this Part.
 
h) If a participating source or new participating source submits an ATU transfer
agreement authorizing the transfer of ATUs for more than one year, as provided
in Section 205.630(a)(2)(B) of this Part, the ATUs shall be automatically
transferred by the Agency from the transferor’s Transaction Account to the
transferee’s Transaction Account. Upon reopening or renewal of the CAAPP
permit or FESOP for any such source, any multiple season transfer agreement that
has three or more years of transfers remaining shall be identified in the renewed

SUBPART E: ALTERNATIVE ATU GENERATION
 
Section 205.500 Emissions Reduction Generator
 
Any participating source, new participating source or general participant may submit a proposal
for issuance of ATUs to it based on VOM emissions reductions, as specified in subsection (a) of
this Section, achieved by any source or group of sources located in the Chicago ozone
nonattainment area with an operating permit(s) other than a participating source or new
participating source. The owner or operator of each source from which the VOM emissions
reductions have been or will be achieved shall certify its acceptance of the terms of the proposal
and that it has achieved or will achieve the emissions reductions specified in the proposal. An
emissions reduction generator may apply for a modification to its operating permit to incorporate
limitations that make the VOM emissions reductions specified in the relevant proposal
enforceable.
 
a) ATUs will only be issued pursuant to this Section if based on actual VOM
emissions reductions that meet one or more of the following:
 
1) If, based on the same actual production rate, VOM emissions at the source
for any seasonal allotment period beginning in 1999 are or will be lower
due to the use of technology or materials at the source than if operating at
the same production rate at the emissions level allowed by applicable
requirements effective in 1996 or any requirements included in the State
Implementation Plan, provided such reductions occurred after 1990;
 
2) The source shuts down a portion or all of its operation(s) after 1996 and
withdraws the relevant operating permit(s), provided the VOM emissions
from the shut down activity or activities will not be distributed elsewhere
within the Chicago ozone nonattainment area;
 
3) The source(s) curtails its seasonal production activity resulting in an actual
reduction in VOM emissions during any seasonal allotment period
beginning in 1999, provided the VOM emissions from the curtailment will
not be distributed elsewhere within the Chicago nonattainment area. Such
emissions reduction shall be based on the difference between the average
production level for the two seasonal allotment periods prior to the year of
curtailment and the curtailed production level, calculated at the VOM
emission rate allowed by applicable requirements effective in 1996; or
 
4) The source shuts down operations or curtails seasonal production activity
as described in subsections (a)(2) and (a)(3) of this Section, respectively,

 
30
and the VOM emissions from the shut down activity or activities or
curtailment will be distributed to a participating or new participating
source or sources within the Chicago ozone nonattainment area, and the
proposal provides that all ATUs issued pursuant to this Section on account
of such shut down or curtailment are to be issued to the corresponding
participating or new participating source or sources.
 
b) If any proposal is based on a shut down of operations, as specified in subsection
(a)(2) of this Section, that results in seasonal emissions reductions of 10 tons or
more, 20 percent of ATUs issued based on such an emissions reduction generator
proposal shall be allocated to the ACMA.
 
c) Any proposal based on seasonal emissions reductions of 10 tons or more and the
Agency’s approval thereof shall be subject to the public notice requirements in
accordance with the regulations governing CAAPP permit or FESOP issuance of
Section 39.5 of the Act [415 ILCS 5/39.5].
 
d) Any proposal submitted shall include the following:
 
1) Information identifying the source(s) from which the VOM emissions
reductions has been or will be achieved and its owner or operator;
 
2) An explanation of the method used to achieve the VOM emissions
reductions;
 
3) Relevant information describing the nature of the underlying activity that
generated the VOM emissions and the relationship of the units at which
the VOM emissions reduction occurred to other units or sources
performing the same or related activity in the Chicago ozone
nonattainment area, if the VOM emissions reduction is attributable to a
partial or complete source shutdown or a production curtailment, as
specified in subsection (a)(2), (a)(3) or (a)(4) of this Section;
 
4) The amount of VOM emissions for the two seasonal allotment periods
prior to the year(s) of curtailment, including supporting calculations, if the
VOM emissions reduction is attributable to a production curtailment as
specified in subsection (a)(3) or (a)(4) of this Section;
 
5) The amount of the VOM emissions reduction, including supporting
calculations and documentation, such as material usage information;
 
6) The name and address of the participating source(s), new participating
source(s) or general participant(s) to which ATUs will be issued, including
the name and telephone number of the account officer for such source or
participant; and
 

 
31
7) The owner or operator of each proposed emission reduction generator
shall certify its acceptance of the terms of the proposal and certify that it
has achieved or will achieve the emissions reductions specified in the
proposal.
 
e) The owner or operator of any emissions reduction generator may modify its
operating permit to incorporate limitations that make the VOM emissions
reductions specified in the relevant proposal enforceable.
 
f) If the emissions reduction generator does not modify its permit, as specified in
subsection (e) of this Section, or experiences a shutdown, as specified in
subsection (a)(2) or (a)(4) of this Section, and the proposal is submitted prior to
the availability of actual VOM emissions data from the relevant seasonal
allotment period, the Agency shall determine if the proposal is acceptable on a
preliminary basis and provide notification of this determination. The Agency
shall not issue final approval, in accordance with subsection (g) of this Section, of
any such proposal until the actual VOM emissions data is submitted.
 
g) The Agency shall notify the participating source, new participating source or
general participant in writing of its final decision with respect to the proposal
within 45 days after receipt of such proposal or receipt of VOM emissions data to
verify that the specified reductions occurred, whichever occurs later. If the
Agency denies or conditionally approves a proposal, this written notice shall
include a statement of the specific reasons for denying or modifying the proposal.
The Agency’s determination as to the approvability of any proposal submitted
pursuant to this Section is subject to review by the Board as provided at 35 Ill.
Adm. Code 105.102, provided the proposed emissions reduction generator is not
requesting a permit revision. If such a permit revision is requested, the applicable
permit review and appeal procedures shall apply.
 
h) If the Agency deems that the proposal is sufficient to receive final approval, the
Agency shall issue ATUs in accordance with the following:
 
1) Any ATUs issued pursuant to this subsection shall be issued to the
participating source(s), new participating source(s) or general participant
identified in the proposal;
 
2) If the emissions reduction generator modifies its operating permit as
specified in subsection (e) of this Section, to incorporate limitations that
make the VOM emissions reductions specified in the relevant proposal
enforceable, ATUs shall be issued on the date such source is required to
comply with the limitations in the permit and for each seasonal allotment
period thereafter in which the VOM emissions reductions are required by
the source’s permit;
 

 
32
3) If the proposal is based on a partial or complete shut down, as specified in
subsection (a)(2) or (a)(4) of this Section, ATUs shall be issued before the
seasonal allotment period for each year specified in the proposal;
 
4) If the emissions reduction generator does not modify its permit and the
proposal is submitted prior to the availability of actual VOM emissions
data from the relevant seasonal allotment period(s), the Agency shall issue
ATUs upon final approval which shall occur after actual VOM emissions
data is evaluated for the relevant seasonal allotment period;
 
5) If the emissions reduction generator includes information on actual VOM
emissions reductions during the seasonal allotment period for which ATUs
are sought, ATUs will be issued by the Agency upon final approval of the
proposal;
 
6) Except as provided in subsection (h)(7) of this Section, ATUs issued
pursuant to this subsection shall only be valid for the seasonal allotment
period in which the emissions reductions were achieved;
 
7) If the VOM emissions reductions specified in a proposal are incorporated
into the emissions reduction generator’s permit or, if the emissions
reduction generator shuts down all or a portion of its operations and
withdraws all relevant operating permits, ATUs issued pursuant to this
subsection shall be valid for the seasonal allotment period following
issuance and for the next seasonal allotment period; and
 
8) The number of ATUs issued pursuant to subsection (h)(2) or (h)(3) of this
Section based on a proposal under subsection (a)(4) of this Section shall
be equal to the number of ATUs otherwise issuable under this Section
reduced by 12 percent.

emergency occurred, subject to the following:
 
a) The owner or operator of the participating source or new participating source shall
submit an initial emergency conditions report to the Agency within two days after
the time when such excess emissions occurred due to the emergency. The
submittal of this initial emergency conditions report shall be sufficient to fulfill
the notice requirements of Section 39.5(7)(k) of the Act [415 ILCS 5/39.5(7)(k)]
as it relates to VOM emissions at the source if the report provides a detailed
description of the emergency, any steps taken to mitigate emissions and corrective
actions taken, to the extent practicable. The final report shall contain the
following information:
 
1) A description of the cause(s) of the emergency and the duration of the
episode;
 
2) Verification that the source was being operated properly at the time of the
emergency;
 
3) A demonstration that the source took all reasonable steps to minimize
excess VOM emissions during the emergency period, including but not
limited to the following actions, if technically and economically feasible:
 
A) The level of operation of the affected emission unit(s) was
minimized;
 
B) The level of emissions from the affected emission units(s) was
minimized by use of alternative raw materials or alternative control
measures;
