Proposed Rule. First Notice.
 
OPINION AND ORDER OF THE
  
This rulemaking proposes revisions to the Board’s regulations regarding exemptions from
air construction and operating permit requirements. The proposal seeks to add four exemptions
to the existing list of 59 permit exemptions in Section 201.146. 35 Ill. Adm. Code 201.146. The
purpose of the amendments is to eliminate permitting delays for minor projects having little
environmental or regulatory impact.
 
The proposal was a joint collaboration by the Illinois Environmental Protection Agency
(Agency) and the Illinois Environmental Regulatory Group (IERG). The proposed amendments
will add four new subsections to the existing list of exemptions found in Section 201.146. The
Board notes that it is simultaneously adopting for first notice another proposal that amends
Section 201.146, entitled Proposed Amendments to Exemptions from State Permitting
Requirements for Plastic Injection Molding Operations (35 Ill. Adm. Code 201.146), R05-20
(Sept. 15, 2005).
 
Today the Board adopts the proponents’ proposal, as amended, for first notice. First-
notice publication in the
Illinois Register
will begin a 45-day period for interested persons to file
public comments with the Board. The Board describes each of the proposed exemptions and the
various issues raised at hearing in more detail below.
 
PROCEDURAL BACKGROUND
 
On February 22, 2005, the proponents filed this proposal for rulemaking pursuant to
Sections 27 and 28 of the Environmental Protection Act (Act) and 35 Ill. Adm. Code
102.202(b).

The Board has held two public hearings in this rulemaking before hearing officer
Amy Antoniolli. The first hearing was held on April 12, 2005, in Chicago and the second
hearing was held on June 14, 2005, in Springfield.

Mr. Don Sutton testified on behalf of the Agency. Mr. Sutton is the manager of the
permit section, Division of Air Pollution Control, Bureau of Air, and has been since 1991. Mr.
Sutton is responsible for issuing construction and operating permits for the Bureau of Air. Ms.
Katherine Hodge, executive director of IERG, also testified on behalf of the proponents.
 
On June 1, 2005, the Agency filed an errata sheet making changes to the proposed rule
language that reflected issues raised at the first hearing.
 
There have been two public comments filed in this rulemaking. The first was filed on
behalf of the Chemical Industry Council of Illinois (CICI) (PC 1), and the second was a post-
hearing comment filed by the proponents in support of the proposal (PC 2). CICI supports this
rulemaking, stating “”[t]his more efficient and targeted use of state resources is both consistent
with the approach taken by our neighboring other Region 5 states and consistent with sound
management of state resources.”
 
SUMMARY OF PROPOSED NEW PERMIT EXEMPTION CATEGORIES
 
  
According to the proponents, the proposed exemptions to Section 201.146 of the Board’s
regulations will improve the Illinois air permitting system and do not threaten the public health
or welfare. PC 2, at 3; Statement at 3. The proponents state that the proposed exemptions will
allow the Agency to dedicate its resources to “projects with greater emission and regulatory
ramifications,” and allow eligible facilities to avoid the costly and time-consuming delays of the
permitting process. PC 2, at 5. Lastly, the proponents state the environment will benefit from
the speedier replacement or addition of improved air control equipment.
Id
.
 
Proposed Section 201.146(hhh) would apply to the replacement or addition of air
pollution control equipment at existing units. Proposed Section 201.146(iii) would apply to
sources that have Federally Enforceable State Operating Permits (FESOPs) and a low potential
to emit. Proposed Section 201.146(jjj) would apply to permitted minor sources that are not
Clean Air Act Permit Program (CAAPP) sources and do not have FESOPs. Proposed Section
201.146(kkk) would apply to insignificant activities at CAAPP sources. Statement at 12.
 
Exemption for Equipment at Existing Emission Units
 
The proponents explain that under the first exemption, proposed subsection (hhh), owners
or operators replacing or adding air pollution control equipment at existing units would be
exempt from obtaining a state construction or operating permit if certain criteria are met. First,
the exemption would only apply to existing units, and the existing unit must be permitted and
have operated in compliance for the past year. Statement at 3.
 
The new pollution control equipment must maintain or improve air pollution control over
the prior levels of target pollutants, and not result in a net increase in emissions of any non-target
criteria pollutant. Statement at 4. This exemption would not apply if sources are required to
comply with different State or Federal regulatory requirements. Finally, required monitoring
equipment must be carried over to the replacement control device and must incorporate current
technology.
Id

Exemption for FESOP Sources With a Low Potential to Emit
 
According to the proponents, some Illinois sources have FESOPs limiting their potential
to emit. Statement at 5. The proponents claim that there can be some projects at FESOP sources
that do not fit under any of the existing listed exemptions under Section 201.146 and that are still
insignificant from a permitting standpoint. Under this second exemption, proposed subsection
(iii), the Agency and IERG propose a “
de minimis
” permitting exemption for minor projects at
minor FESOP sources that meet certain criteria.
 
The proponents state that this exemption is limited to the installation of new emission
units or modifications of existing emission units at FESOP sources where the potential to emit
any regulated air pollutant absent air pollution equipment from the new or modified emission
unit is less than 0.1 pound per hour or 0.44 tons per year. Statement at 5. Also, the proposal
requires that raw materials and fuels that cause or contribute to emissions not contain any
hazardous air pollutant equal to or greater than 0.01% by weight. Statement at 6. The
proponents state that the exemption thresholds correspond to insignificant activity designations
for CAAPP sources. Further, the proponents state this exemption is limited by the applicability
of New Source Performance Standards (NSPS) and New Source Review (NSR), both permitting
requirements under the Clean Air Act. Statement at 7. Further, the exemption would not apply
if outstanding compliance or enforcement issues exist.
 
Exemption for Minor Sources That Are Not CAAPPs or FESOPs
 
The Agency and IERG state this exemption, proposed subsection (jjj), would only apply
to permitted sources that are not major sources and do not have FESOPs. Statement at 8. The
proponents state that this exemption, like in subsection (iii), would be limited to sources with the
same low potential to emit any regulated air pollutant absent air pollution equipment from the
new or modified unit. The proponents state the exemption would also be available for minor
sources that have a slightly greater potential to emit up to 0.5 pounds per hour, so long as the
facility notifies the Agency of its intent to construct or install a new emissions unit or make a
modification. Only after notification can the facility begin construction, installation, or
modification. Statement at 9.
 
The proponents state this exemption is also limited by the applicability of NSPS and
NSR, both permitting requirements under the Clean Air Act. This provision, state the Agency
and IERG, would require permitting if the additional emissions from the project could change
the sources’s status with respect to its potential to emit. Further, the exemption would not apply
if outstanding compliance or enforcement issues exist. Statement at 10.
 
Insignificant Activities Exemption
 
According to the proponents, the proposed subsection (kkk) creates a list of insignificant
activities similar to the list of insignificant activities at CAAPP sources exempt from requiring a
CAAPP permit modification found at Section 201.210. Like sources under Section 201.210 and
201.211, owners or operators must notify the Agency when it adds insignificant activities. For

 
 
4
example, the proponents state that under the proposed revisions, the insignificant activities
exemptions for state permit modifications would match those existing exemptions from CAAPP
permit modifications. Statement at 11. Notwithstanding this exemption, facilities must comply
with otherwise applicable emission standards or other regulatory requirements.
 
ISSUES RAISED AT HEARING
 
Supporting Data
 
Ms. Hodge presented an analysis of the Agency’ s air emissions permit data in support of
the proposal. Ms. Hodge explained that the permit data used to provide the statistics for this
rulemaking was gathered in calendar years 2001 and 2002. Tr.1 at 11. Subsequent to the first
hearing and prior to the second, the Agency filed additional data from 2003 and 2004 regarding
the Bureau of Air’s permitting actions. The data showed that a large number of air permits were
issued for projects with low levels of emissions. IERG’s investigation revealed that
approximately 70% of all air construction permits were for projects with no emission increases
or for emission increases of less than one ton per year. Tr.1 at 12. IERG states that Illinois is the
only state in Region V that does not have at least some form of
de minimis
permit exception.
Accordingly, IERG contends that Illinois must proceed with air permit streamlining. Tr.1 at 13.
 
Technical Feasibility and Economic Reasonableness
 
IERG states that together with the Agency it has identified 5,620 smaller source permits,
called lifetime permits, out of nearly 7,000 total sources permitted by the Bureau of Air. Tr.1 at
15. The Agency adds that approximately 790 sources are classified as needing Clean Air Act
Title V permits, 450 of which are FESOPs. Tr.1 at 19. The Agency currently permits 1,800 to
1,900 sources a year: 900 to 1,000 of which are construction permits, and the rest being
operating permits. Tr.1 at 20. Of this number, the Agency would no longer need to issue
approximately 200 to 230 permits per year (120-150 smaller source and FESOP source permits,
and 60-80 Title V source permits).
 
The Agency sees the loss of fees from potentially exempt permitees in relation to the
administrative costs of permitting those sources as “a wash.” Tr.1 at 21. The Agency explains
that the sources that would qualify under the proposed exemptions are “minimum fee payers,”
which means the cost of their construction permit is $500 and operating permit is $200.
Id
. The
amount of time required in clerical work and engineering to issue the permit cancels out the
permit fee for those sources.
Id
.
 
Administrative Advantages for the Agency
 
Mr. Sutton testified the Agency issues roughly 1,900 permits a year, yet has, at any given
time, a 900 to 1,000 permit backlog. The Agency believes this rulemaking would allow it to
reduce the processing time and reallocate resources to the sources in Illinois that pollute the
most. Tr.1 at 18, 31. The proponents reason that the Agency would routinely issue permits for
the projects that qualify for these proposed permit exemptions, so even if there is some increase

 
 
5
in emissions, the Agency would almost certainly issue permits for these types of projects
anyway. Tr.2 at 9.
 
According to Mr. Sutton, the largest five percent of air sources emit 95% of allowable
emissions in Illinois. Tr.1 at 52. For actual emissions reported, it is the largest 15% that make
up 95% of emissions for all criteria.
 
Types of Sources Fitting the Proposed Exemptions
 
Mr. Sutton states that approximately 150 permits exempt under the proposed language
would be construction permits for smaller sources and FESOP sources. Mr. Sutton further
estimates that approximately 80 more Title V sources would fit within the proposed exemptions.
Tr.1 at 32.
 
The Agency clarified that to qualify for an exemption under the proposed language, a
source must be in compliance with air regulations, having had no enforcement action brought
against it by the Agency, for at least a year. Tr.1 at 43-44.
 
Rule Language Questions
 
There was some discussion at the first hearing about the terms “target pollutant” and
“collateral pollutant” that were included in IERG’s originally proposed rule language. Mr.
Sutton explained that a target pollutant is the pollutant you are trying to control. An example of
a collateral pollutant is ozone, which may not be emitted into the atmosphere by the facility, but
rather created in the atmosphere by the release of Volatile Organic Material (VOM). Therefore,
if the goal is to reduce a collateral pollutant, ozone, one must first control the target pollutant,
VOM.
 
The Board also inquired what the Agency meant by proposing the language “different
regulatory or newly proposed regulatory requirements will not apply to the unit.” The Agency
stated the language referred to new federal requirements, the most likely being newly proposed
requirements under the National Emission Standards for Hazardous Air Pollutants (NESHAP).
Tr.1 at 78. Mr. Sutton explained that under the Maximum Acheivable Control Technology
(MACT) standard, as another example, new sources must comply whether they are adopted or
not. Tr.1 at 79. The Agency state it also purposely left the language open to include new state
regulations as well. Tr.1 at 78. The Board suggested modifying the term “regulation” with
“State or Federal.” Tr.1 at 79.
 
DISCUSSION
 
Today the Board adopts the proponents’ proposal to add four more exemptions to the
existing list of exemptions in Section 201.146 of the Board’s air regulations. Because of the
existing 59 categorical exemptions, the Agency already has some procedures for determining
compliance with permit exemptions. The proposed exemptions do not require any specific
recordkeeping for inspectors to verify that the facility is exempt. Yet, each owner or operator
has the responsibility and the risk for inaccurate determinations. This assumption of

 
 
6
responsibility is the same as what is currently required for existing permit exemptions under
Section 201.146.
 
The proposed new exemptions incorporate additional safeguards. Subsections (hhh), (iii)
and (jjj) require that sources be in compliance to take advantage of the proposed permit
exemptions. Further, in proposed subsection (jjj)(1)(B), the facility must provide the Agency
with notification before initiating the project.
 
The proposed rule language also clearly states that where a project is regulated by
nonattainment NSR, prevention of significant deterioration (PSD), NSPS, or NESHAPs, the
proposed exemptions will be unavailable and the permit process is still mandatory.
 
After the first hearing and before the second hearing, the Agency filed amendments to the
proposed rule language. The amendments changed the term “collateral pollutant” in proposed
subsection 201.146(hhh)(3) to “non-targeted criteria air pollutant.” The purpose of this change is
to clarify that any changes or additions in air control equipment under the (hhh) exemption must
not produce an increase in emissions of any criteria pollutant that may occur as a result of an
allowed release of a target pollutant. The amendments also added the terms “State or Federal” so
that (hhh)(4) reads: “Different State or Federal regulatory requirements or newly proposed
regulatory requirements will not apply to the unit to modify regulatory requirements that do not
apply to the unit.” The amendments further add a Board note to (hhh)(4), stating: “All sources
must comply with underlying Federal regulations and future State regulations.”
 
The Board received no testimony or comments regarding the DCEO’s decision not to
perform an economic impact study on this rulemaking. Further, the Agency testified at hearing
that the fees generated from the sources this rulemaking proposes to exempt basically cancel the
administrative and engineering costs required for the Agency to permit those sources. The Board
finds the proposed amendments technically feasible and economically reasonable for both the
source as well as the State. The Board also finds that the proposed exemptions will not
negatively impact the environment because they allow only a negligible increase in emissions.
 
The Board adopts the proponents’ proposal as amended by the Agency. The Board
makes only those additional technical corrections necessary to keep the rule language consistent
with regulatory language typically reviewed by the Joint Committee on Administrative Rules and
adopted by the Board.
 
CONCLUSION
 
The Board adopts the proponents’ proposed exemptions from state air permitting
proposal, as amended by the Agency, for first-notice publication in the
Illinois Register
. By
allowing
de minimis
sources an exemption from state permitting requirements, the Board finds
this rulemaking will benefit the sources that will qualify for the proposed exemptions as well as
the Agency which implements and enforces them.

pollution control construction permit for the construction or modification of an
emission unit or activity that is an insignificant activity as addressed by Section
201.210 or 201.211 of this Part. Section 201.212 of this Part must still be
followed, as applicable. Other than excusing the owner or operator of a CAAPP

 
19
source from the requirement to obtain an air pollution control construction permit
for such emission units or activities, nothing in this provision shall alter or affect
the liability of the CAAPP source for compliance with emission standards and
other requirements that apply to such emission units or activities, either
individually or in conjunction with other emission units or activities constructed,
modified or located at the source.
