APPEAL OF CAAPP PERMIT

NOW COMES Petitioner, Ameren Energy Generating Company and Gibson City Power

Plant

("Petitioner" or "Ameren"), pursuant to Section 40.2 of the Illinois Environmental

Protection Act

("Act") (415 ILCS 5/40.2) and 35 Ill.Adm.Code § 105.300

et seq.,

and requests a

hearing before the

Board to contest certain conditions contained in the Clean Air Act Permit

Program

("CAAPP") renewal permit

l

(the "permit") issued on March 19, 2009, pursuant to

Section 39.5 of the Act (415 ILCS

5/39.5)

and attached hereto as Exhibit 1. 35 Ill.Adm.Code §§

105.210(a) and (b).

See

Exhibit 1. Pursuant to Section 40.2(a) of the Act and 35 IlI.Adm.Code

§§ 105.302(e), this Petition is timely filed with the Board.

In support

of its Petition to appeal Conditions 5.6.2, 5.7.2, 5.9.2, 7.1.3(f), 7.1.3(f)(iv),

7.1.5(a)(iii)(A), 7.1.8(a)(iii), 7.1.9(1), 7.1.9(m), 7.1.10(e), and 7.1.12(e) and its request to stay

these Conditions, Petitioner states

as follows:

1

Application No. 01050068; 1.0. No. 053803AAL

I. BACKGROUND

(35 IlI.Adm.Code § 105.304(a»

1.'

The Gibson City Power Plant ("Gibson City"), Illinois Environmental Protection

Agency ("Agency") LD. No. 053803AAL is an electric generating station owned and operated

by Ameren Energy Generating Company. Gibson City Power Plant operates as a peaking

station, generating electric power when sufficient electric power

is not available from other

sources.

The Gibson City Power Plant electrical generating units ("EGUs") are combustion

turbines and subject

to the CAAPP (415 ILCS 5/39.5). The Gibson City Power Plant is located

at 545 North Jordan Drive Gibson City, Ford County, Illinois 60936. Ford County is attainment

for all National Ambient Air Quality Standards. The Agency issued the permit on March

19,

2009.

II. REQUEST FOR PARTIAL STAY OF THE PERMIT

2.

Historically, the Board has granted partial stays in permit appeals where a

petitioner has so requested.

See, e.g., Midwest Generation,

LLC, Will County Generating Station

v.

Illinois Environmental Protection Agency,

PCB 06-156 (July 20,2006) (granted stay of the

effectiveness

of contested conditions of a construction permit);

Dynegy Midwest Generation, Inc.

(Vermilion Power Station)

v.

Illinois Environmental Protection Agency,

PCB 06-194 (October

19,2006) (granted stay "of the portions of the permit Dynegy contests");

Dynegy Midwest

Generation, Inc. (Havana

Power Station)

v.

Illinois Environmental Protection Agency,

PCB 07-

115 (October 4,2007) (same);

Hartford Working Group

v.

Illinois Environmental Protection

Agency,

PCB 05-74 (November 18, 2004) (granted stay of the effectiveness of Special Condition

2.0 of an air construction permit);

Community Landfill Company and City of Morris

v.

Illinois

Environmental

Protection Agency,

PCB 01-48 and 01-49 (Consolidated) (October 19, 2000)

(granted stay of effectiveness of challenged conditions for two permits of two parcels of the

-2-

landfill);

Allied Tube

&

Conduit Corp.

v.

Illinois Environmental Protection Agency,

PCB 96-IOS

(December 7,1995) (granted stay of the effectiveness of Conditions 4(a), 5(a), and 7(a) of an air

pennit).

3.

Ameren requests in this instance that the Board exercise its inherent discretionary

authority to grant a partial stay

of the CAAPP permit, staying only those conditions or portions

of conditions indicated in Exhibit 2,

i.e.,

Conditions 5.6.2, 5.7.2, 5.9.2, 7.1.3(f), 7.1.3(f)(iv),

7.1.5(a)(iii)(A), 7.1.S(a)(iii),

7.1.9(1), 7.1.9(m), 7.1.10(e), and 7. 1.1 2(e), during the pendency of

this appeaL

III.

ISSUES ON

APPEAL

(35 1lI.Adm.Code §§ 105.304(a) (2)-(4»

Following are the issues that Ameren appeals and seeks a stay for, presented sequentially.

4.

Condition 5.6.2 Emissions of Hazardous Air Pollutants

Petitioner

objects to this Condition because it is arbitrary, capricious, and unauthorized

by law to the extent it imposes

an emission limit to ensure that the source is not a major source of

hazardous air pollutant emissions. As set forth in Condition 5.1.1, the source is not a major

source for hazardous air pollutant emissions and the pennit was not issued based on the source

being a major source for hazardous air pollutant emissions. This condition is, therefore, in

excess

of the Agency's authority, unauthorized by law, arbitrary and capricious, and

unreasonable. Accordingly, this Condition should be deleted and stayed during the pendency

of

this appeal.

5.

Condition 5.7.2 HAP Testing to Verify Minor Source Status

Petitioner

objects to this Condition because it is unnecessary given the fuel and emission

limitations contained within the pennit and therefore is arbitrary, capricious, unauthorized by law

and unreasonable. This Condition requires the source to verify compliance with Condition 5.6.2,

-3-

Electronic Filing - Received, Clerk's Office, April 23, 2009

* * * * * PCB 2009-093 * * * *

---

which for the reasons set forth above should be deleted. Accordingly, this Condition should be

deleted and stayed during the pendency

of this appeal.

6.

Condition 5.9.2 Records for HAP Emissions

Petitioner objects to this Condition because is it arbitrary, capricious, unauthorized

by

law and unreasonable. This Condition requires the source to record emissions to demonstrate

compliance with Condition 5.6.2, which for the reasons set forth above should be deleted.

Accordingly, this Condition should be deleted and stayed during the pendency

of this appeal.

7.

Condition 7.1.3(f) Startup Provisions

Petitioner objects to this Condition because it is unauthorized by law, arbitrary and

capricious. This Condition incorrectly fails to incorporate certain limitations or provisions from

the current

CAAPP permit, which are applicable requirements. Accordingly, this provision

should be modified and stayed during the pendency

of this appeal.

8.

Condition 7.1.3(3)(f)(iv) Startup Provisions

Petitioner objects to this Condition because it is arbitrary, capricious, unauthorized

by

law and unreasonable.

This Condition requires the source to fulfill the record keeping

requirements

of Condition 7.1.1 O( e), which for the reasons set forth below should be deleted.

Accordingly, this Condition should be modified and stayed during the pendency

of this appeal.

9.

Condition 7.1.5(a)(iii)(A) Control Requirements and Work Practices

Petitioner objects to this Condition because it unreasonable, arbitrary and capricious. The

permit contains a quarterly inspection requirement

of emission related components that is not

reflective

of actual operating conditions. The units do not operate on a regular schedule, thus the

imposed schedule may require inspections on a non-operating unit. Therefore, this Condition is

-4-

---

arbitrary and capricious, unauthorized by law and unreasonable. Accordingly, this Condition

should be modified and stayed during the pendency of this appeal.

10.

Condition 7.1.8(a)(iii) Monitoring Requirements

Petitioner objects

to this Condition because it is unauthorized by law, unreasonable,

redundant, arbitrary and capricious. The Agency may not require a source to operate a unit when

the unit is otherwise not operating in order

to assess compliance. Accordingly, this Condition

should be modified and stayed during the pendency

of this appeal.

II.

Condition 7.1.9(1) Recordkeeping Requirements - Shutdowns

Petitioner objects to this Condition because it is unauthorized by law, unreasonable,

redundant, arbitrary and capricious. The source maintains records

of the date, time and duration

of the shutdown. The additional records required by this Condition are redundant and not

necessary to ensure compliance with applicable requirements. Accordingly, this Condition

should be modified and stayed during the pendency of this appeal.

12.

Condition 7.1.9(m) Recordkeeping Requirements - Start Ups

Petitioner objects to this Condition because it is unauthorized by law, unreasonable,

vague, redundant, arbitrary and capricious to the extent it requires the source to maintain records

that go beyond those necessary to ensure compliance with applicable requirements. This

Condition is not limited to maintaining records for startups resulting in an opacity exceedance

and requires records that are not necessary to ensure compliance with applicable requirements.

The requirement that the unit achieve "normal operation" within thirty minutes does not reflect

current operating conditions. It is unclear what information must be included when describing

the startup and there is no basis for requiring the source to provide the Agency with a reason for

the startup. The requirement

to maintain a maintenance and repair log is duplicative of the

-5-

---

requirements in Condition 7.1.9(c). Furthermore, records related to exceedances of limitations

during startups should not be required unless conditions exist which could result in a deviation

from the applicable requirements.

Therefore, this Condition is unauthorized by law,

unreasonable, vague, redundant, arbitrary and capricious. Accordingly, this Condition should be

modified and stayed during the pendency

of this appeal.

13.

Condition 7.1.10(e) Reporting Startups

Petitioner objects to this Condition because it is unauthorized

by law, redundant,

unreasonable, arbitrary and capricious. Several other Conditions, including 7.1.10(a) and

7.1.1

O(b) require the necessary reporting to ensure compliance with applicable requirements.

The information required by this Condition

is not necessary to ensure compliance with

applicable requirements.

Therefore, this Condition is unauthorized by law, redundant,

unreasonable, arbitrary and capricious. Accordingly, this Condition should be deleted and stayed

during the pendency

of this appeal.

14.

Condition 7.1.12(e) Compliance Procedures

Petitioner objects to this Condition because it is unauthorized by law, unreasonable,

redundant, arbitrary and capricious to the extent it conflicts with the compliance obligations in

the original construction permit and Condition 7.1.6(d). According, this Condition should be

modified and stayed during the pendency

of this appeal.

15.

The Company has met with the Agency and believes the majority, if not all, of the

above issues and conditions can be resolved. However, any such resolution could not occur

within the time frame required for appeal.

So that the parties have sufficient time to resolve

issues and conditions in dispute, including

if necessary the filing of an amended CAAPP permit

application, Ameren requests that the conditions set forth herein be stayed.

WHEREFORE. for the reasons set forth above, Ameren appeals Conditions 5.6.2, 5.7.2,

5.9.2, 7.1.3(f), 7.1.3(f)(iv), 7.1.5(a)(iii)(A), 7.1.8(a)(iii), 7.1.9(1), 7.1.9(m),

7. 1.1O(e), and

7.1.12(e)

of the CAAPP renewal permit issued March 19, 2009, for the Gibson City Power Plant

and requests that the Board order the Agency to delete or modify the conditions as set forth

above. Additionally, Ameren requests that the Board stay Conditions 5.6.2, 5.7.2,.5.9.2, 7.1.3(f),

7. 1.3 (f)(iv), 7.1.5(a)(iii)(A), 7.1.8(a)(iii), 7.1.9(1), 7.1.9(m), 7. 1.1O(e), and 7.1.12(e) during the

pendency

of this appeal as set forth in Exhibit 2. Ameren will extend its current practices under

the CAAPP permit replaced

by this permit issued March 19, 2009, where the Board stays

Conditions appealed herein and will,

of course, comply with all requirements of the Board's

regulations applicable to Gibson City Power Plant during the pendency

of this appeal.

minimize startup emissions, duration of individual starts,

and frequency of startupsll.

i.

This 'authorization does not relieve the Permittee

from the continuing obligation to demonstrate that

all reasonable efforts are made to minimize startup

emissions, duration of individual startups and

frequency of startups.

ii.

The Permittee shall conduct startup of the each

affected turbine(s) in accordance with written

procedures prepared by the Permittee and maintained

at the facility, in the control room for the each

affected turbine(s), that are specifically developed

to minimize emissions from startups and that include,

at a minimum, the following measures:

A.

The Permittee shall conduct startup of an

affected turbine in accordance with the

manufacturer's written instructions or other

written instructions prepared by the source

owner or operator and maintained on site.

B.

The Permittee shall take the following measures

to minimize emissions resulting from startups,

the duration of startups, and minimize the

frequency of startups:

I.

Operating in accordance with the

manufacturer's written operating and

startup procedures, including a pre-check

of the unit, or other written procedures

developed and maintained by the source

owner or operator so as to minimize the

duration of startups and the emissions

associated with startups. These

procedures should allow for review of

operating parameters of the unit during

startup, or shutdown as necessary to make

adjustments to reduce or eliminate excess

emissions.

II.

Maintaining units in accordance with

written procedures developed and

maintained by the source owner or

III. The procedures described above shall be

reviewed at least annually to make

necessary adjustments and shall be made

available to the Illinois EPA upon

request.

iv.

The Permittee shall fulfill applicable recordkeeping

and reporting requirements of Condition 7.l.9(m) and

7.1.10(e) .

v.

As provided by 35 lAC 201.265, an authorization in a

permit for excess emissions during startup does not

shield a Permittee from enforcement for any violation

of applicable emission standard(s) that occurs during

startup and only constitutes a prima facie defense to

such an enforcement action provided that the

Permittee has fully complied with all terms and

conditions connected with such authorization.

g.

Malfunction and Breakdown Provisions

Subject to the following terms and conditions, the

Permittee is authorized to continue operation of an

affected turbine in violation of the applicable standards

in Condition 7.l.3(b) and the hourly emission limits in

Condition

7.1~6

in the event of "a malfunction or breakdown

of the affected turbines. This authorization is provided

pursuant to 35 lAC 201.149, 201.161 and 201.2€2, as the

Permittee has applied for such authorization in its

application, generally explaining why such continued

operation would be required to provide essential service or

to prevent risk of injury to personnel or severe damage to

equipment, and describing the measures that will be taken

to minimize emissions from any malfunctions and breakdowns.

This authorization supersedes the general prohibition in

Condition 9.2.3 against continued operation in such

circumstances.

i.

This authorization only allows such continued

operation as necessary to provide essential service

or prevent risk of injury to personnel or severe

damage to equipment and does not extend to continued

operation solely for the economic benefit of the

Permittee.

ii.

Upon occurrence of excess emissions due to

malfunction or breakdown, the Permittee shall as soon

as practical repair the turbine, remove the affected

turbine from service, or undertake other action so

that excess emissions cease.

iii. The Permittee shall fulfill the applicable

recordkeeping and reporting requirements of

Conditions 7.1.9(n) and 7.1.10(f). For these

25

---

7.1. 4

purposes, time shall be measured from the start of a

particular incident. The absence of excess emissions

for a short period shall not be considered to end the

incident if excess emissions resume. In such

circumstances, the incident shall be considered to

continue until corrective actions are taken so that

excess emissions cease or. the Permittee takes the

affected turbines out of service.

iv.

Following notification to the Illinois EPA of a

malfunction or breakdown with excess .emissions, the

Permittee shall comply with all reasonable directives

of the Illinois EPA with respect to such incident,

pursuant to 35 rAC 201.263.

v.

This authorization does not relieve the Permittee

from the continuing obligation to minimize excess

emissions during malfunction or breakdown. As

provided by 35 lAC 201.265, an authorization in a

.permit for continued operation with excess emissions

during malfunction and breakdown does not shield the

Permittee from enforcement for any such violation and

only constitutes a prima facie defense to such an

enforcement action provided that the Permittee has

fully complied with all terms and conditions

connected with such authorization.

Non-Applicability of Regulations of Concern

a.

The affected turbines are not subject to the New Source

Performance Standards {NSPS) for Stationary Combustion

Turbines, 40 CFR Part 60, Subpart KKKK, because the

affected turbines did not commence construction,

modification, or reconstruction after February 18, 2005

pursuant to 40 CFR 60.4305(a), and are therefore subject to

40 CFR Part 60, Subpart GG for Stationary Gas Turbines.

Note: To qualify for this non-applicability, the Permittee

has certified that the turbines have not been modified or

reconstructed after February 18, 2005.

b.

The affected turbines are not subject to the National

Emissions Standards for Hazardous Air Pollutants for

Stationary Combustion Turbines, 40 CFR Part 63, Subpart

YYYY, because the affected turbines are not IDcated at a

major source of HAP emissions, pursuant to 40 CFR 63.6085.

c.

The affected turbines are not subj ect to 35 rAC 212.321 or

212.322, due to the unique nature of such units, a process

weight rate can not be set so that such rules can not

reasonably be applied, pursuant to 35 rAC 212.323.

Pursuant to 40 CFR 60.335 (b) (7), if the owner

or operator elects .to install and certify a NOli.

CEMS under 40 CFR 60.334(e), then the initial

performance test required under 40 CFR 60.8 may

be done in the following alternative manner:

Perform a minimum of 9 reference method runs,

with a minimum time per run of 21 minutes, at a

single load level, between 90 and 100 percent

of peak (or the highest physically achievable)

load, pursuant to 40 CFR 60.335 (b) (7) (i) .

Use the test data both to demonstrate

compliance with the applicable NOli. emission

Pursuant to 40 CFR 60.335(b) (10), if the owner

or operator is required under 40 CFR

60.334 (i) (1) or (3) to periodically determine

the sulfur content of the fuel combusted in the

turbine, a minimum of three fuel samples shall

be collected during the performance test.

Analyze the samples for the total sulfur

content of the fuel using:

For gaseous fuels, ASTM D1072-80, 90

(Reapproved 1994); D3246-81, 92, 96; D4468-85

(Reapproved 2000); or D6667-01 (all of which

are incorporated by reference, see 40 CFR

60.17).

The applicable ranges of some ASTM

methods mentioned above are not adequate to

Monitoring Requirements

a.

i.

If an affected turbine is routinely operated or

exercised to confirm that the turbine will operate

when needed, the operation and opacity of the

affected turbine shall be formally observed by

operating personnel for the affected turbine or a

member of source owner or operator's environmental

staff on a regular basis to assure that the affected

turbine is operating properly, which observations

shall be made at least every six months.

ii.

If an affected turbine is not routinely operated or

exercised, i.e., the time interval between operation

of an affected turbine is typically greater than six

months, the operation and opacity of the affected

turbine shall be formally observed as provided above

35

---

each time the source owner or operator carries out a

scheduled exercise of the affected turbine.

iii. The source owner or operator shall also conduct

formal observations of operation and opacity of an

affected turbine upon written request by the Illinois

EPA. With the agreement of the Illinois EPA, the

source owner or operator may schedule these

observations to take place during periods when it

would otherwise be operating the affected turbine.

Note:

The formal observation required above

is

not

intended to be a USEPA Test Method 9 opacity test, nor does

the observation require a USEPA Test Method 9 certified

observer.

It is intended to be performed

by

personnel

familiar with the operation of the affected turbine. who

would be able to make a determination based from the

observed opacity as to whether or not the affected turbine

was running properly, and subsequently initiate a

corrective action if necessary.

b.

The affected turbine shall comply with the applicable

monitoring requirements of 40 CFR 60.334(h), below.

Monitoring of fuel nitrogen content shall not be required

while the facility does not claim an allowance for fuel-

bound nitrogen. Monitoring for sulfur content in fuel is

not required while natural gas is the only fuel fired in

the affected turbine -and the requirements of 40 CFR

60.334(h)3(i) or (ii) are met.

Pursuant to 40 CFR 60.334(h), the owner or operator of any

stationary gas turbine subject to the provisions of this

subpart:

Shall monitor the total sulfur content of the fuel being

Pursuant to 40 CFR 60.334(h) (3), notwithstanding the

provisions of 40 CFR 60.334(h) (1), the owner or operator

may elect not to monitor the total sulfur content of the

gaseous fuel combusted in the turbine, if the gaseous fuel

is demonstrated to meet the definition of natural gas in 40

CFR 60.331(u), regardless of whether an existing custom

schedule approved by the administrator for subpart GG

requires such monitoring. The owner or operator shall use

one of the following sources of information to make the

required demonstration:

The gas quality characteristics in a current, valid

purchase contract, tariff sheet or transportation contract

for the gaseous fuel, specifying that the maximum total

sulfur content of the fuel is 20.0 grains/IOO scf or less,

pursuant to 40 CFR 60.334 (3) (i); or

Representative fuel sampling data which show that the

sulfur content of the gaseous fuel does not exceed 20

grains/100 scf. At a minimum, the amount of fuel sampling

data specified in section 2.3.1.4 or 2.3.2.4 of appendix D

by USEPA, the owners or operators may obtain 80

2

emissions and requires the

owners and operators to monitor NO

of the affected units as such matters are addressed by Titles I and V of the

Clean Air Act. This permit also does not affect the source's responsibility to
