`5.0``	``OVERALL SOURCE CONDITIONS`

`5.1``	``Source Description`

    5.1.1	This permit is issued based on the source requiring a CAAPP permit as a major source of VOM and HAP emissions.

`5.2``	``A``pplicable Regulations`

    5.2.1	Specific emission units at this source are subject to particular regulations as set forth in Section 7 (Unit-Specific Conditions) of this permit.

    5.2.2	In addition, emission units at this source are subject to the following regulations of general applicability:

    a.	No person shall cause or allow the emission of fugitive particulate matter from any process, including any material handling or storage activity, that is visible by an observer looking generally overhead at a point beyond the property line of the source unless the wind speed is greater than 40.2 kilometers per hour (25 miles per hour), pursuant to 35 IAC 212.301 and 212.314.

    b.	No person shall cause or allow the emission of smoke or other particulate matter, with an opacity greater than 30 percent, into the atmosphere from any emission unit other than those emission units subject to the requirements of 35 IAC 212.122, pursuant to 35 IAC 212.123(a), except as allowed by 35 IAC 212.123(b) and 212.124.

    c.	No person shall cause or allow the emission of sulfur dioxide into the atmosphere from any process emission unit to exceed 2,000 ppm  [35 IAC 214.301].

`d.``	``Many processes listed in the unit-specific conditions in Section 7 are subject to 35 IAC 212.321(a).  It is written in detail here any reference made to it in Section 7, where appropriate.  This rule states that:  No person shall cause or allow the emission of particulate matter into the atmosphere in any one hour period from any new process emission unit, either alone or in combination with the emission of particulate matter from all other similar process emission units for which construction and modification commenced on or after April 14, 1972, at a source or premises, exceeds the allowable emission rates specified below of 35 IAC 212.321 [35 IAC 212.321(a)].`

    The emissions of particulate matter into the atmosphere in any one hour period from each of the affected coating lines shall not exceed the allowable emission rates specified in the following equation:

`E = A(P)`^`B`^

    P = Process weight rate in metric or English tons per

        hours; and

    E = Allowable emission rates in kilograms or pounds

        per hour.

        and

    A = 2.54

    B – 0.534

    The permitted emissions for fee purposes of 249 tons/yr also represents a limit established to prevent the installation of this process from being a major modification pursuant to the PSD rules, 40 CFR 52.21.  Will County is now classified as part of the Chicago Metropolitan Area nonattainment area, but at the time when Dow obtained the construction permit (March, 1978) the area was classified as attainment for ozone.  35 IAC 203 was not in effect at that time.

`5.6``	``General Recordkeeping Requirements`

    5.6.1	Emission Records

    The Permittee shall maintain records of the following items for the source to demonstrate compliance with Condition 5.5.1, pursuant to Section 39.5(7)(b) of the Act:

    Total annual emissions on a calendar year basis for the emission units covered by Section 7 (Unit Specific Conditions) of this permit.

`5.6.2``	``Retention and Availability of Records`

    a.	All records and logs required by this permit shall be retained for at least five years from the date of entry (unless a longer retention period is specified by the particular recordkeeping provision herein), shall be kept at a location at the source that is readily accessible to the Illinois EPA or USEPA, and shall be made available for inspection and copying by the Illinois EPA or USEPA upon request.

    b.	The Permittee shall retrieve and print, on paper during normal source office hours, any records retained in an electronic format (e.g., computer) in response to an Illinois EPA or USEPA request for records during the course of a source inspection.

    5.7	General Reporting Requirements

    5.7.1	General Source-Wide Reporting Requirements

    The Permittee shall promptly notify the Illinois EPA, Compliance Section of noncompliance with the permit requirements as follows, pursuant to Section 39.5(7)(f)(ii) of the Act.  Reports shall describe the probable cause of such deviations, and any corrective actions or preventive measures taken.

    5.7.2	Annual Emissions Report

    The annual emissions report required pursuant to Condition 9.7 shall contain emissions information for the previous calendar year.

`5.8``	``General Operational Flexibility/Anticipated Operating Scenarios`

    This process emits VOM and non-VOM blowing agents that are introduced in one step of the process but may be emitted at any of three downstream processes including storage.  These blowing agents may be changed provided that total VOM does not exceed the limit in Condition 5.5.1.  The Illinois EPA must be notified if the HAP material in the blowing agent is changed to another HAP material.

`5.9``	``General Compliance Procedures`

    5.9.1	General Procedures for Calculating VOM and non-VOM Emissions

    Compliance with the source-wide emission limits specified in Condition 5.5 shall be based on the recordkeeping and reporting requirements of Conditions 5.6 and 5.7, and Compliance Procedures in Section 7 (Unit Specific Conditions) of this permit.

    For the purpose of estimating HAP emissions from equipment at the source, the vapor weight percent (based on a 1992 USEPA survey) of each HAP for each product times the VOM emissions contributed by that product is acceptable.

    The computer model described in Exhibit 220-6 of the application and also used in determination of the ERMS baseline may be used to determine VOM, HAP, and non-VOM emissions from the foam board manufacturing process.

    6.0	EMISSION REDUCTION MARKET SYSTEM (ERMS)

    6.1	Description of ERMS

    The ERMS is a “cap and trade” market system for major stationary sources located in the Chicago ozone nonattainment area.  It is designed to reduce VOM emissions from stationary sources to contribute to further reasonable progress toward attainment, as required by Section 182(c) of the Clean Air Act.

    The ERMS addresses VOM emissions during a seasonal allotment period from May 1 through September 30.  Once the ERMS begins, participating sources must hold “allotment trading units” (ATUs) for their actual seasonal VOM emissions.  Each year participating sources are issued ATUs based on allotments set during initial issuance of the sources’ CAAPP permits.  These allotments are established from historical VOM emissions or “baseline emissions” lowered to provide the emission reduction from stationary sources required for further progress.

    By December 31 of each year, the end of the reconciliation period following the seasonal allotment period, each source shall have sufficient ATUs in its account to cover its actual VOM emissions during the preceding season.  An account’s balance as of December 31 will include any valid ATU transfer agreements entered into as of December 31 of the given year, provided such agreements are promptly submitted to the Illinois EPA for entry into the account database.  The Illinois EPA will then retire ATUs in sources’ accounts in amounts equivalent to their seasonal emissions.  When a source does not appear to have sufficient ATUs in its account, the Illinois EPA will issue a notice to the source to begin the process for Emissions Excursion Compensation.

    In addition to receiving ATUs pursuant to their allotments, participating sources may also obtain ATUs from the market, including ATUs bought from other participating sources and general participants in the ERMS that hold ATUs (35 IAC 205.630) and ATUs issued by the Illinois EPA as a consequence of VOM emission reductions from an Emission Reduction Generator or an Intersector Transaction (35 IAC 205.500 and 205.510).  During the reconciliation period, sources may also buy ATUs from a secondary reserve of ATUs managed by the Illinois EPA, the Alternative Compliance Market Account (35 IAC 205.710).  Sources may also transfer or sell the ATUs that they hold to other sources or participants (35 IAC 205.630).

    6.2	Applicability

    This source is considered a “participating source” for purposes of the ERMS, 35 IAC Part 205.

    6.3	Obligation to Hold Allotment Trading Units (ATUs)

    a.	Pursuant to 35 IAC 205.150(c)(1) and 205.720, and as further addressed by condition 6.8, as of December 31 of each year, this source shall hold ATUs in its account in an amount not less than the ATU equivalent of its VOM emissions during the preceding seasonal allotment period (May 1 - September 30) not including VOM emissions from the following, or the source shall be subject to “emissions excursion compensation,” as described in Condition 6.4.

    i.	VOM emissions from the polystyrene manufacturing process (Section 7.7), the vinyl ester manufacturing process (Section 7.8) or the storage terminal (Section 7.1).  These processes are included in the CAAPP permit only because of HAP emissions.

    ii.	VOM emissions from insignificant units and activities as identified in Section 3 of this permit, in accordance with 35 IAC 205.220;

    iii.	Excess VOM emissions associated with startup, malfunction or breakdown of an emission unit as authorized elsewhere in this permit, in accordance with 35 IAC 205.225;

    iv.	Excess VOM emissions to the extent allowed by a Variance, Consent Order, or Compliance Schedule, in accordance with 35 IAC 205.320(e)(3);

    v.	Excess VOM emissions that are a consequence of an emergency as approved by the Illinois EPA, pursuant to 35 IAC 205.750; and

    vi.	VOM emissions from certain new and modified emission units as addressed by Section 6.7(b), if applicable, in accordance with 35 IAC 205.320(f).

    b.	Notwithstanding the above condition, in accordance with 35 IAC 205.150(c)(2), if a source commences operation of a major modification, pursuant to 35 IAC Part 203, the source shall hold ATUs in an amount not less than 1.3 times its VOM emissions attributable to such major modification during the seasonal allotment period, determined in accordance with the construction permit for such major modification or applicable provisions in Section 7.0 of this permit.

    6.4	Market Transaction

    a.	The source shall apply to the Illinois EPA for and obtain authorization for a Transaction Account prior to conducting any market transactions, as specified at 35 IAC 205.610(a).

    b.	The Permittee shall promptly submit to the Illinois EPA any revisions to the information submitted for its Transaction Account, pursuant to 35 IAC 205.610(b).

    c.	The source shall have at least one account officer designated for its Transaction Account, pursuant to 35 IAC 205.620(a).

    d.	Any transfer of ATUs to or from the source from another source or general participant must be authorized by a qualified Account Officer designated by the source and approved by the Illinois EPA in accordance with 35 IAC 205.620 and the transfer must be submitted to the Illinois EPA for entry into the Transaction Account database.

    6.5	Emission Excursion Compensation

    Pursuant to 35 IAC 205.720, if the source fails to hold ATUs in accordance with Condition 6.3, it shall provide emissions excursion compensation in accordance with the following:

    a.	Upon receipt of an Excursion Compensation Notice issued by the Illinois EPA, the source shall purchase ATUs from the ACMA in the amount specified by notice, as follows:

    i.	The purchase of ATUs shall be in an amount equivalent to 1.2 times the emissions excursion; or

    ii.	If the source had an emissions excursion for the seasonal allotment period immediately before the period for the present emission excursion, the source shall purchase ATUs in an amount equivalent to 1.5 times the emissions excursion.

    b.	If requested in accordance with paragraph (c) below or in the event that the ACMA balance is not adequate to cover the total emissions excursion amount, the Illinois EPA will deduct ATUs equivalent to the specified amount or any remaining portion thereof from the ATUs to be issued to the source for the next seasonal allotment period.

    c.	Pursuant to 35 IAC 205.720(c), within 15 days of receipt of an Excursion Compensation Notice, the owner or operator may request that ATUs equivalent to the amount specified be deducted from the source’s next seasonal allotment by the Illinois EPA, rather than purchased from the ACMA.

    6.6	Quantification of Seasonal VOM Emissions

    a.	The methods and procedures specified in Section 5 and 7 of this permit for determining VOM emissions and compliance with VOM emission limitations shall be used for determining seasonal VOM emissions for purposes of the ERMS, with the following exceptions  [35 IAC 205.315(b)]:

    No exceptions

    b.	The Permittee shall report emergency conditions at the source to the Illinois EPA in accordance with 35 IAC 205.750, if the Permittee intends to deduct VOM emissions in excess of the technology-based emission rates normally achieved that are attributable to the emergency from the source’s seasonal VOM emissions for purposes of the ERMS.  These reports shall include the information specified by 35 IAC 205.750(a), and shall be submitted in accordance with the following:

    i.	An initial emergency condition report within two days of the time when such excess emissions occurred due to the emergency; and

    ii.	A final emergency condition report, if needed to supplement the initial report, within 10 days after the conclusion of the emergency.

    6.7	Annual Account Reporting

    a.	For each year in which the source is operational, the Permittee shall submit, as a component of its Annual Emission Report, seasonal VOM emission information to the Illinois EPA for the seasonal allotment period. This report shall include the following information  [35 IAC 205.300]:

    i.	Actual seasonal emissions of VOM from the source;

    ii.	A description of the methods and practices used to determine VOM emissions, as required by this permit, including any supporting documentation and calculations;

    iii.	A detailed description of any monitoring methods that differ from the methods specified in this permit, as provided in Section 205.337 of this Subpart;

    iv.	If a source has experienced an emergency, as provided in 35 IAC 205.750, the report shall reference the associated emergency conditions report that has been approved by the Illinois EPA; 

    v.	If a source’s baseline emissions have been adjusted due to a variance, consent order or CAAPP permit compliance schedule, as provided for in 35 IAC 205.320(e)(3), the report shall provide documentation quantifying the excess VOM emissions during the season that were allowed by the Variance, Consent Order, or Compliance Schedule, in accordance with 35 IAC 205.320(e)(3); and

    vi.	If a source is operating a new or modified emission unit for which three years of operational data are not yet available, as specified in 35 IAC 205.320(f), the report shall specify seasonal VOM emissions attributable to the new emission unit or the modification of the emission unit.

    b.	This report shall be submitted by November 30 of each year, for the preceding seasonal allotment period.

    6.8	Allotment of ATUs to the Source

    a.	i.	The allotment of ATUs to this source is 742 ATUs per seasonal allotment period.

    ii.	This allotment of ATUs reflects the Illinois EPA's determination that the source's baseline emissions were 84.3 tons.

    A.	This determination includes the use of 1994 and 1995 as baseline seasons.

    B.	This determination includes adjustment to actual emissions to account for voluntary over-compliance at the source, e.g., a reduction in use of blowing agent per unit of production, pursuant to 35 IAC 205.320(d) as further addressed in Section 7 of this permit.

    iii.	The source's allotment reflects 88% of the baseline emissions (12% reduction) except for the VOM emissions from specific emission unit excluded from such reduction, pursuant to 35 IAC 205.405 including units complying with MACT or using BAT, as identified in Condition 6.11 of this permit.

    iv.	ATUs will be issued to the source's Transaction Account by the Illinois EPA annually.  These ATUs will be valid for the seasonal allotment period following issuance and, if not retired in this season, the next seasonal allotment period.

    v.	Condition 6.3(a) becomes effective beginning in the seasonal allotment period following the initial issuance of ATUs by the Illinois EPA into the Transaction Account for the source.

    b.	Contingent Allotments for New or Modified Emission Units

    Not applicable.

    c.	Notwithstanding the above, part or all of the above ATUs will not be issued to the source in circumstances as set forth in 35 IAC Part 205, including:

    i.	Transfer of ATUs by the source to another participant or the ACMA, in accordance with 35 IAC 205.630;

    ii.	Deduction of ATUs as a consequence of emission excursion compensation, in accordance with 35 IAC 205.720; and

    iii.	Transfer of ATUs to the ACMA, as a consequence of shutdown of the source, in accordance with 35 IAC 205.410.

    6.9	Recordkeeping for ERMS

    The Permittee shall maintain copies of the following documents as its Compliance Master File for purposes of ERMS [35 IAC 205.700(a)]:

    a.	Seasonal component of the Annual Emission Report;

    b.	Information on actual VOM emissions, as specified in detail in Sections 5 and 7 of this permit and Condition 6.6(a); and

    c.	Any transfer agreements for the purchase or sale of ATUs and other documentation associated with the transfer of ATUs.

`d.``	``The ERMS program does not include the polystyrene manufacturing process (Section 7.7), the vinyl ester manufacturing process (Section 7.8), or the storage terminal (Section 7.9).  Therefore, the records specified in Condition 6.9(a) are not required for those operations.`

    6.10	Federal Enforceability

    Section 6 becomes federally enforceable upon approval of the ERMS by USEPA as part of Illinois' State Implementation Plan.

# `7.7.3``	``Applicability Provisions and Applicable Regulations`

`a.``	``An ``“``affected polystyrene plant``”``, for the purpose of these unit specific conditions is a process line that includes any of the various pieces of equipment listed in Condition 7.9.2.`

`b.``	``The polystyrene process is subject to the NESHAP for Group IV polymers, 40 CFR 63 Subpart JJJ.  This includes an LDAR Program.  Special provisions include the following:`

`i.``	``Due to vapor pressure specifications, all storage vessels are classified as Group 2 storage vessels.`

`ii.``	``For the LDAR program, 40 CFR 63 Subpart JJJ incorporates the LDAR requirements of 40 CFR 63 Subpart H.  The Permittee shall also comply with the equipment leak provisions of 35 IAC 218 Subpart Q.`

`iii.``	``The specific provisions within 40 CFR 63 Subpart JJJ that for the common vent units the Permittee demonstrates compliance is Section 63.1316(c)(iii)(A).  This rule requires that TOC emissions be reduced by 98 weight percent or to a concentration of 20 ppmv on a dry basis, whichever is less stringent.  If an owner or operator elects to comply with the 20 ppmv standard, the concentration shall include a correction to 3 percent oxygen only when supplemental combustion air is used to combust the emissions.`

`iv.``	``The units in Condition 7.7.2 (excluding fugitive leaks) not ducted to a common vent are exempt from control for the following reasons:`

`A.``	``TV-114, TV-155, and V-1070 are exempt pursuant to 40 CFR 63.1314(d) which states that the provisions of Section 63.1314 do not apply to storage vessels containing styrene at existing affected sources.`

`B.``	``V-1021, V-112, V-901, and V-902 are not storage vessels as defined in Section 63.1312.`

`C.``	``V-930 is a Group 2 storage vessel as defined in Section 63.1312.`

`D.``	``Tank truck loading is not a thermoplastic product process unit as defined in Section 63.1312.`

`c.``	``VOM emissions from the material recovery section (vacuum vent) shall not exceed 0.12 kg of VOM per 1,000 kg of polystyrene produced (0.12 pounds of VOM per 1,000 pounds of polystyrene).  Compliance with Condition 7.7.3(b)(iii) shall be deemed compliance with this limit (35 IAC 218.642).`

`d.``	``No person shall cause or allow the emission of more than 8 lb/hr of organic material into the atmosphere from any emission unit unless controlled by a thermal or catalytic incinerator which reduces emissions by 85%.  If no odor nuisance exists, the limitations shall only apply to photochemically reactive material (35 IAC 218.301 and 218.302).`

    Styrene is a photochemically reactive material.  Compliance with Condition 7.7.3(b)(iii) shall be deemed compliance with this limit.

`e.``	``Continuous emission units within the polystyrene process other than the material recovery section are subject to 35 IAC 218 Subpart RR as explained in Section 218.960(b)(1).  However, the Permittee qualifies those units under the exemption in Section 218.960(d).  Emissions from those units shall not exceed 1.0 ton per calendar year and from all units included with the exemption not exceed 5.0 tons per calendar year.  Continuous units other than the material recovery section does not include storage tanks or tank truck loading.`

    f.	The movement of product, polystyrene pellets, by air conveyors is subject to 35 IAC 212.321(a).  This rule is written out in Condition 5.2.2(d).  The pellets are not considered to be emitters of VOM.

# `7.7.4``	``Non-Applicability of Regulations of Concern`

`b.``	``The polystyrene process is not subject to 40 CFR 60 Subpart DDD, NSPS for Polymer Manufacturing, because:`

`i.``	``The process was constructed prior to the applicability date of January 10, 1989; and`

`ii.``	``Units that were subject to both the NSPS and NESHAP are now subject to only the NESHAP cited in Condition 7.7.3(b).`

`c.``	``Storage tanks are not subject to 35 IAC 218.120 because the applicability requirements in Section 218.119 exempt tanks due to the vapor pressure and/or tank volume.  The tanks are exempt from 35 IAC 218.122(b) due to the vapor pressure exemption in Section 218.122(c).`

`d.``	``The Dowtherm heater is not subject to 35 IAC 216.121, which states that CO emissions shall not exceed 200 ppm because the heat input is less than 10 mmBtu/hr.`

# `7.7.5``	``Control Requirements`

# `7.8.3``	``Applicability Provisions and Applicable Regulations`

    a.	An “affected vinyl ester resin plant” for the purpose of these unit specific conditions is a process consisting of the units listed in Condition 7.8.2 excluding the Dowtherm heater.

    i.	The vinyl ester resin process is subject to 35 IAC 218 Subpart V, Batch Operations.

`A.``	``Within Section 218.500(c) are two levels of operation defined as de minimis and exempted from the control requirements of Section 218.501.  The Permittee has control equipment that complies with Section 218.501(a), although the entire process may qualify for the exemption in Section 218.500(c)(2) of uncontrolled VOM emissions of less than 15 ton/year.`

`B.``	``35 IAC 218.501(a) requires that the control equipment reduce VOM emissions by an overall average efficiency of 90 percent, or ppmv, per batch cycle.`

`C.``	``The Permittee has not used the provision in 35 IAC 218.501(c) that states that if control equipment was operated prior to March 15, 1995 and can demonstrate that 90% control cannot be achieved, that 81% control is acceptable until the control device is replaced.`

    D.	The units in Condition 7.8.2 that are not controlled are not part of the batch process but are storage, loading, and drumming operations.

    ii.	No person shall cause or allow the emission of more than 8 lb/hr of organic material into the atmosphere from any emission unit unless controlled by a thermal or catalytic incinerator which reduces emission by 85%.  If no odor nuisance exists, the limitations shall only apply to photochemically reactive material.  (35 IAC 218.301 and 218.302).

    Styrene, the principal VOM emitted, is a photochemically reactive material.

    Compliance with condition 7.8.3(a)(i) shall be deemed compliance with this limit.

# `In the event of a malfunction or breakdown of the chilled scrubber, the Permittee is authorized to continue operation of the batch vinyl ester resin process in violation of the applicable requirement of 35 IAC 218.501, as necessary to prevent risk of injury to personnel or severe damage to equipment.  This authorization is subject to the following requirements:`

`i.``	``The Permittee may complete processing of the materials in the equipment vented to the chilled scrubber at the time of the breakdown, but no new batch of materials may begin until the chilled scrubber is functioning in its normal temperature and flow rate range.`

# `ii.``	``The Permittee shall fulfill the applicable recordkeeping and reporting requirements of Conditions 7.8.9(b) and 7.8.10(a).`

# `7.8.4``	``Non-Applicability of Regulations of Concern`

`a.``	``The vinyl ester resin process is not subject to 35 IAC 218 Subpart RR, Miscellaneous Organic Chemical Manufacturing Processes because 35 IAC 218.960(a)(1) and (b)(1)(A) both state that emission units that are regulated by 218 Subpart V are not regulated by Subpart RR.  This process is regulated by Subpart V.`

# `b.``	``The vinyl ester resin process is not subject to any NSPS or NESHAP regulations because none of the chemicals produced are listed in tables of those rules as follows:`

    PROJECT SUMMARY

`I.``	``INTRODUCTION`

    This source has applied for a Clean Air Act Permit Program (CAAPP) operating permit for its existing operation.  The CAAPP is the program established in Illinois for the operating permits for significant stationary sources required by the Federal Clean Air Act, as amended in 1990.  The conditions in a CAAPP permit are enforceable by both the Illinois Environmental Protection Agency (Illinois EPA) and the USEPA.

    The Dow Chemical Company is located at 26332 Frontage Road in Channahon, Will County, Illinois.  The source manufactures expanded polystyrene foam boards which are used as insulation in the building industry.  Dow also manufactures polystyrene and vinyl ester resin and operates a storage distribution terminal for liquid chemicals.

`III.``	``EMISSIONS`

    This source is required to have a CAAPP permit since it is a major source of emissions.  The proposed permit limits the maximum annual emissions from significant emission units at the source.  Insignificant activities at this source are not accounted for in the source limit.

    For purposes of fees, the source is allowed the following emissions:

  ----------------------------------- ------------- ------------------------------ --------- --------------------------- --------- ------------------------------- --------- ---------------------------------- ---------

`IV.``	``APPLICABLE EMISSION STANDARDS`

    All emission sources in Illinois must comply with the Illinois Pollution Control Board’s emission standards.  The Board’s emission standards represent the basic requirements for source in Illinois.

    All emission sources in Illinois must comply with the Federal New Source Performance Standard (NSPS).  The Illinois EPA is administering NSPS in Illinois on behalf of the United States EPA under a delegation agreement.

    All emission sources in Illinois must comply with the Federal National Emission Standards for Hazardous Air Pollutants (NESHAP).  The Illinois 

    Page 3

    EPA is administering NESHAP in Illinois on behalf of the United States EPA under a delegation agreement.

`V.``	``PROPOSED PERMIT`

## [`CAAPP`]{.underline}

    A CAAPP permit contains conditions listing the applicable state and federal air pollution control regulations that apply to a source.  The permit conditions also establish emission limits and appropriate compliance procedures.  The appropriate compliance procedures may include inspections, work practices, monitoring, recordkeeping, and reporting to show compliance with these requirements.  The Permittee must carry out these procedures on an on-going basis to demonstrate that the source is operating in accordance with the requirements of the permit.

## [`Title I`]{.underline}

    In addition to the above conditions, a combined Title I/CAAPP permit contains terms and conditions established by the Illinois EPA pursuant to authority found in Title I provisions, e.g., 40 CFR 52.21 – federal Prevention of Significant Deterioration (PSD) and 35 IAC Part 203 – Major Stationary Sources Construction and Modification.  Notwithstanding the expiration date on the first page of the permit, the Title I conditions remain in effect pursuant to Title I provisions until the Illinois EPA deletes or revises them in accordance with Title I procedures.

    Because this source is located in the Chicago ozone nonattainment area and emits volatile organic material, the permit includes conditions to implement the Emission Reduction Market System (ERMS).  The ERMS is a market-based program designed to reduce emissions from stationary sources to contribute to further reasonable progress toward attainment, as further described in section 6 of the permit.  The permit contains the Illinois EPA’s determination of the source’s baseline emissions and allotment of trading units under the ERMS, and identifies units not subject to further reductions.  The permit also provides that the source must begin to operate under the ERMS following the initial issuance of trading units to the source.  This will occur for the 2000 seasonal allotment period (rather than the 1999 season as originally intended by the ERMS) due in part to delays in the initial issuance of CAAPP Permits.  These delays, which have occurred nationally, are attributable to a variety of causes including the unforeseen complexity of processing these permits and gaps in national guidance.  Even though operation under the ERMS will not officially start until the 2000 seasonal allotment period, detailed recordkeeping and reporting of seasonal emissions was required beginning in 1998, which will document emission reductions achieved by sources in 1999 in preparation for the ERMS.

`VI.``	``REQUEST FOR COMMENTS`

    It is the Illinois EPA’s preliminary determination that this source’s permit application meets the standards for issuance of a CAAPP permit.  The Illinois EPA is therefore proposing to issue a CAAPP permit, subject to the conditions proposed in the draft permit.

    Comments are requested on this proposed action by the Illinois EPA and the proposed conditions on the draft permit.  If substantial public interest is shown in this matter, the Illinois EPA will consider holding a public hearing in accordance with 35 Ill. Adm. Code Part 164.
