     (Rulemaking - Air) 
 
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 205.315       CAAPP Permits for ERMS Sources 
 
a) 
 Except as provided in Section 205.316(c) of this Subpart, the The Agency shall 
determine the baseline emissions for each participating source in accordance with 
Section 205.320 of this Subpart, through its final permit action on a new or 
modified CAAPP permit for the each such source.  The Agency’s baseline 
emissions determination may be appealed in accordance with the CAAPP appeal 
procedures specified in Section 40.2 of the Act [415 ILCS 5/40.2].  If the permit 
conditions establishing a source’s baseline emissions are appealed, the baseline 
emissions for the source shall be as proposed in the source’s ERMS application 
 during the pendency of the appeal.  During the pendency of the appeal, ATUs 
shall be allotted to the source pursuant to the part of the source’s proposed 
baseline emissions that is not disputed in the appeal.  If such source’s seasonal 
VOM emissions exceed the ATUs it holds at the end of reconciliation periods 
during the pendency of the appeal, the source will not be deemed to have had an 
emissions excursion to the extent that such seasonal VOM emissions do not 
exceed the amount it proposed as its baseline in its ERMS application, less 
reductions required pursuant to Section 205.400(c) or (e) of this Part, if 
applicable.  Such source shall not be allowed to sell ATUs during the pendency of 
the appeal. 
 
b) 
 Except as provided in Section 205.316(c) of this Subpart, the The Agency shall 
determine, in accordance with Sections 205.330 and 205.335 of this Subpart, the

 17
participating source to determine seasonal emissions through its final permit 
action on a new or modified CAAPP permit for the each such source.  The 
Agency's determination of the methods and practices applicable may be appealed 
in accordance with the CAAPP appeal procedures specified in Section 40.2 of the 
Act [415 ILCS 5/40.2]. 
 
c) 
 Except as provided in Section 205.316(c) of this Subpart, the The Agency shall 
determine, in accordance with Section 205.405(b) of this Part, if an emission unit 
qualifies for exclusion from further reductions in its final permit action on a new 
 or modified CAAPP permit for each such source.  The Agency’s determination 
may be appealed in accordance with the CAAPP appeal procedures specified in 
Section 40.2 of the Act [415 ILCS 5/40.2 ].  If the permit conditions establishing 
the Agency’s BAT determination are appealed, ATUs shall be allotted to the 
source for any emission unit for which the Agency’s BAT determination is being 
appealed with the emissions reduction required by Section 205.400(c) or (e) of 
this Part during the pendency of the appeal.  If the seasonal VOM emissions for 
the subject emission unit(s) exceed the ATUs that are attributed to the unit(s) 
during the pendency of the appeal, the source will not be deemed to have an 
emissions excursion to the extent that such seasonal VOM emissions do not 
exceed the amount of ATUs that would be attributed to this unit if the BAT 
exclusion was accepted.  Such source shall not be allowed to sell ATUs during the 
pendency of the appeal. 
 
d) The 
 CAAPP permit for a allotment for each participating source shall specify the 
allotment for each seasonal allotment period shall be specified in its CAAPP 
permit. 
 
e)      To the extent possible, the Agency shall initiate the procedures of 35 Ill. Adm.

1)      In the case of a name change of the participating source or new 
participating source where ownership is not altered, appropriate 
documentation shall be submitted to revise the Transaction Account to 
reflect the name change; or 
 
  
  
  
2)      In the case of an ownership change of the participating source or new 
participating source, the allotment shall also
 
be transferred by the owner or 
operator of the permitted source to the new owner or operator, or the new 
owner or operator shall submit a statement to the Agency certifying that 
 
 18
such transfer is not occurring and demonstrating that necessary ATUs are 
or will be available by other means for the intended operation of the 
source. 
 
g)      Upon reopening or renewal of the CAAPP permit for any participating source or 
new participating source, any multiple season transfer agreement, as provided in 
Section 205.630(a)(2)(B) of this Part, that has three or more years of transfers 
remaining shall be identified in the renewed or reissued CAAPP permit for each 
such source. 
 
h)      Upon reopening or renewal of the CAAPP permit for any participating source or 
new participating source, any ATUs that will be issued by the Agency for three

a) 
 Any participating or new participating source shall not operate without a CAAPP 
permit or FESOP. 
 
1)  
 If a source has a CAAPP permit containing ERMS provisions and the 
source elects to obtain a different permit in lieu of the CAAPP permit, the 
source shall apply for and obtain a FESOP that contains ERMS provisions 
including, but not limited to, emissions calculation methodologies, 
baseline emissions, and allotment for each seasonal allotment period, all of 
which are identical to those provisions contained in its CAAPP permit.  
 
2) 
 If a participating or new participating source does not have a CAAPP 
permit containing ERMS provisions and the source elects to obtain a 
permit other than a CAAPP permit, the source shall apply for and obtain a 
FESOP that contains, in addition to other necessary provisions, federally 
enforceable ERMS provisions, including baseline emissions, allotment for 
each seasonal allotment period, identification of any units deemed to be 
insignificant activities for the purposes of the ERMS, emissions 
calculation methodologies, and provisions addressing all other applicable 
 requirements of this Part.

or modified FESOP for the source.  The Agency’s baseline emissions 
 
 19
determination may be appealed in accordance with the appeal procedures 
specified in Section 40 of the Act [415 ILCS 5/40].  If the permit 
conditions establishing a source’s baseline emissions are appealed, the 
baseline emissions for the source shall be as proposed in the source’s 
ERMS application during the pendency of the appeal.  During the 
pendency of the appeal, ATUs shall be allotted to the source pursuant to 
the part of the source’s proposed baseline emissions that is not disputed in 
the appeal.  If such source’s seasonal VOM emissions exceed the ATUs it 
holds at the end of reconciliation periods during the pendency of the 
appeal, the source will not be deemed to have had an emissions excursion 
to the extent that such seasonal VOM emissions do not exceed the amount 
it proposed as its baseline in its ERMS application, less reductions 
required pursuant to Section 205.400(c) or (e) of this Part, if applicable.  
Such source shall not be allowed to sell ATUs during the pendency of the 
appeal. 
 
2) 
 The Agency shall determine, in accordance with Section 205.405(b) of 
 this Part, if an emission unit qualifies for exclusion from further reductions 
in its final permit action on a new or modified FESOP for the source.  The 
Agency’s determination may be appealed in accordance with the appeal 
procedures specified in Section 40 of the Act [415 ILCS 5/40].  If the 
permit conditions establishing the Agency’s BAT determination are 
appealed, ATUs shall be allotted to the source for any emission unit for 
which the Agency’s BAT determination is being appealed with the 
emissions reduction required by Section 205.400(c) or (e) of this Part 
during the pendency of the appeal.  If the seasonal VOM emissions for the 
subject emission unit(s) exceed the ATUs that are attributed to the unit(s) 
during the pendency of the appeal, the source will not be deemed to have 
an emissions excursion to the extent that such seasonal VOM emissions do 
not exceed the amount of ATUs that would be attributed to this unit if the 
BAT exclusion was accepted.  Such source shall not be allowed to sell 
ATUs during the pendency of the appeal. 
 
c) 
 The Agency shall determine, in accordance with Sections 205.330 and 205.335 of

new participating source to determine seasonal emissions through its final permit 
action on the new or modified FESOP for such source.  The Agency's 
determination of the methods and practices applicable may be appealed in 
accordance with the appeal procedures specified in Section 40 of the Act [415 
 ILCS 5/40].
 
d) 
 When a FESOP for a participating source or new participating source is 
transferred from the current permittee to another person: 
 
1) 
 In the case of a name change of the participating source or new 
participating source where ownership is not altered, appropriate 
 
 20
documentation shall be submitted to revise the Transaction Account to 
reflect the name change; or 
 
2) 
 In the case of an ownership change of the participating source or new 
participating source, the allotment shall also be transferred by the owner or 
operator of the permitted source to the new owner or operator, or the new 
owner or operator shall submit a statement to the Agency certifying that 
such transfer is not occurring and demonstrating that necessary ATUs are 
or will be available by other means for the intended operation of the

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 205.335       Sampling, Testing, Monitoring and Recordkeeping Practices 
 
 
 25
The owner or operator of a participating source or new participating source shall conduct 
sampling, perform testing, conduct monitoring and maintain records as needed to support its 
method for determining seasonal emissions in accordance with Section 205.330 of this Subpart 
and to demonstrate compliance with this Part.  Such sampling, testing, monitoring and 
recordkeeping shall be, at a minimum, as stringent as that required by any applicable requirement 
and any permit condition.  The Agency shall establish the practices applicable to each such 
source in the source’s CAAPP permit or FESOP. 
 
(Source:  Amended at __ Ill. Reg.  _____, effective ______________)  
 
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.

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 
with Section 205.320(f) of this Part, the allotment shall be increased by the 
modified portion of the baseline emissions amount, reduced by 12 percent, except 
as provided in Section 205.405 of this Subpart. 
 
f)      Except as provided in subsection (h) of this Section, any new participating source 
shall not be issued ATUs by the Agency, but shall be required to hold ATUs at 
the end of the reconciliation period as specified in Section 205.150(d) of this Part 
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 
or reissued CAAPP permit or FESOP for each such source.

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.

Section 205.730       Excursion Reporting 
 
Upon issuance of each Excursion Compensation Notice to any source that has already had one 
previous admitted or adjudicated emissions excursion, the source shall submit to the Agency any 
additional reports required by the source’s CAAPP permit or FESOP pursuant to Section 
39.5(7)(f) of the Act [415 ILCS 5/39.5(7)(f)].  
 
(Source: Amended at __ Ill. Reg.  _____, effective ______________)  
 
Section 205.750       Emergency Conditions 
 
VOM emissions that are a consequence of an emergency, and are in excess of the technology-
based emission rates which are achieved during normal operating conditions, to the extent that 
such excess emissions are not caused by improperly designed equipment, lack of preventative 
maintenance, careless or improper operation, or operation error, shall be deducted from the 
 
 36
calculation of actual VOM emissions during the seasonal allotment period in which the 
 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; 
 
C)      The duration of the excess emissions was minimized; and 
 
 D)      The amount of VOM emissions from other emission units at the 
source or other sources located in the Chicago ozone 
nonattainment area owned or operated by the person or entity were 
reduced; 
 
4)      A demonstration that appropriate corrective action(s) were taken 
promptly; 
 
5)      A demonstration that the affected emission units were: 
 
A)      Being carefully and properly operated at the time of the 
emergency, including copies of appropriate records and other 
relevant evidence; 
 
 
 37
B)      Properly designed; and 
 
C)      Properly maintained with appropriate preventative maintenance; 
and 
 
6)      An estimate of the amount of VOM emissions that occurred during the 
emergency in excess of the technology-based emission factor achieved 
during normal operating conditions, including supporting data, the 
relevant emissions factor, and calculations. 
 
b)      The owner or operator of any such source may supplement its initial emergency 
conditions report within 10 days after the conclusion of the emergency situation.  
If an initial emergency conditions report is not supplemented, such report is 
deemed the final emergency conditions report.  If, however, an initial emergency 
conditions report is supplemented, the combination of such initial report plus the 
supplemental information is deemed the final emergency conditions report. 
 
c)      The Agency must approve, conditionally approve or reject the findings in the final 
 emergency conditions report, submitted by the source, in writing within 45 30 
days after receipt of the initial emergency conditions a complete
 
report, subject to 
the following: 
 
1)      If the Agency concurs with the emergency conditions report, the source is 
not required to hold ATUs for the excess VOM emissions attributable to 
the emergency; 
 
2)      If the Agency approves with conditions or rejects the emergency 
conditions report, the source shall be required to hold ATUs by the end of 
the reconciliation period in an amount not less than the emissions 
identified as excess in the emergency conditions report or provide 
emissions excursion compensation in accordance with Section 205.720 of 
this Subpart, if an emissions excursion occurred; 
 
3)      If the Agency approves with conditions an emergency conditions report, 
the Agency must identify in its written notice the amount of VOM 
emissions that are not attributable to an emergency; and 
 
4)      If the Agency approves with conditions or rejects a source’s emergency 
conditions report, the source may raise the emergency as an affirmative 
defense pursuant to Section 39.5(7)(k) of the Act [415 ILCS 5/39.5(7)(k)] 
in any action brought for noncompliance with this Part or an action 
brought to review the Agency’s issuance of an Excursion Compensation 
Notice, as provided in Section 205.720(d) of this Subpart. 
 
 
 38
d)      Nothing in this Section relieves any source of any obligation to comply with other 
 applicable requirements, permit conditions, or other provisions addressing 
emergency situations.

Section 205.760       Market System Review Procedures 
 
Beginning in 2000, the Agency shall prepare an Annual Performance Review Report that 
addresses the effect of VOM emissions reductions in the Chicago ozone nonattainment area on 
progress toward meeting the RFP requirements and achieving attainment of the NAAQS for 
ozone by 2007. 
 
a)      The Annual Performance Review Report will review trends and patterns which 
may have emerged in the operation of the ERMS, and shall include, but not be 
limited to, the following: 
 
1)      Total aggregate VOM emissions during the previous seasonal allotment 
period; 
 
2)      The number of ATUs retired for compliance purposes or for air quality 
benefit, currently being banked, or used by new participating sources for 
the previous seasonal allotment period; 
 
3)      An evaluation of trading activities, including sources with no trading 
activity, sources that are net purchasers of ATUs and sources that are net 
sellers of ATUs; 
 
4)      ACMA transactions since the preparation of the previous report and the 
account balance; 
 
5)      A summary of emissions reduction generator and inter-sector proposals; 
 
6) Distribution of transactions by geographic area or character of source; 
 
7)      Availability of ATUs for purchase; 
 
8)      The average market price for ATU transactions from the previous seasonal 
allotment period; and 
 
9)      Trends and spatial distributions of hazardous air pollutants. 
 
b)      The Agency shall prepare the Report by June 30 May 15 of the year following the 
seasonal allotment period addressed by the Report.  The Agency will make copies 
of its Report available to interested parties upon request.
