COMPLAINANT; and
 
ERIC E. BOYD AND SUSANNAH A. SMETANA, SEYFARTH SHAW, APPEARED ON
BEHALF OF RESPONDENT.
 
OPINION AND ORDER OF THE BOARD (by C.A. Manning):
 
This enforcement action concerns air emissions from a natural gas compressor station in
Glenarm, Sangamon County, Illinois. The Illinois Attorney General, on behalf of the People of
the State of Illinois (People) and at the request of the Illinois Environmental Protection Agency
(Agency), filed a complaint against Panhandle Eastern Pipe Line Com
pany (Panhandle), a
natural gas pipeline transmission company. The People allege that Panhandle, at its Glenarm
compressor station (Glenarm Station), violated requirements of the Environmental Protection
Act (Act) (415 ILCS 5/1
et seq.
(2000)) to limit air emissions. Those requirements include the
Prevention of Significant Deterioration (PSD) program, which is designed to protect air quality
from diminishing in areas with relatively clean air.
 
At Glenarm Station, Panhandle uses compressor engines to recompress natural gas,
ensuring that the gas will continue to move along the pipeline. By burning fuel, these
compressor engines emit nitrogen oxides (NOx) into the air. NOx is a pollutant under the
federal Clean Air Act (42 U.S.C. § 7401
et seq.
). In 1988, Panhandle retired 12 of the 15
compressor engines at Glenarm Station and added four new compressor engines, leaving the
station with a total of seven compressor engines. For this change in compressor engines,
Panhandle received a construction permit from the Agency in 1988.
 
The construction permit and each of Panhandle’s subsequent operating permits limited
NOx emissions from the four new compressor engines to 461.3 tons per year (TPY). As stated
on each permit, the 461.3 TPY limit on NOx emissions was designed to avoid the applicability
of the PSD regulations by ensuring that the construction change in 1988 would not increase NOx
 
 

 
2
emissions by 40 TPY or more. An increase of 40 TPY or more would be considered a “major
modification” under PSD, which would subject Panhandle to more stringent and expensive
requirements, including analyzing the construction project’s impact on air quality and installing
the best available control technology (BACT) on the four new compressor engines to limit their
NOx emissions. Because these types of permits are designed to avoid “major” modification
status, they are referred to as “minor source” permits or “PSD avoidance” permits. Panhandle
never appealed the 461.3 TPY NOx condition in these permits. Panhandle admits that the four
new engines have consistently emitted NOx in excess of the 461.3 TPY limit and were
continuing to do so, at least through 1998—the last full year before the People brought this
enforcement action. The main issue that the Board faces in this enforcement proceeding is to
determine the legal implications of these uncontested facts.
 
The People allege that Panhandle’s NOx emissions in excess of 461.3 TPY have resulted
in violations of the Act. The People assert that Panhandle is subject to PSD requirements, with
which Panhandle admits it has not complied. The People also allege that Panhandle violated its
permit by emitting NOx in excess of the 461.3 TPY limit. The People seek a total civil penalty
of $2,218,759 against Panhandle for the violations, as well as costs and attorney fees of
$128,902.25. Panhandle asserts that it is not subject to PSD and that no violations took place,
raising five affirmative defenses. Panhandle also argues that if the Board imposes any civil
penalty, the total amount should be no more than $160,000, and that costs and attorney fees are
inappropriate in this case.
 
For the reasons provided in this opinion, the Board (1) finds that Panhandle violated the
Act and orders Panhandle to cease and desist from further violations; (2) imposes a total civil
penalty on Panhandle of $850,000; and (3) awards the People costs and attorney fees of
$115,750.25 because Panhandle repeatedly and, since 1996, knowingly violated the Act.
 
PSD is a critical program created by the federal Clean Air Act to keep our air safe to
breathe. In Illinois, the Act makes it a violation of State law to violate PSD requirements. The
Act also prohibits violations of air permit conditions. Panhandle sought to avoid the extra costs
of complying with PSD’s stringent requirements by applying for a minor source permit. Under
the law, Panhandle could receive a minor source permit for its construction project without
meeting any PSD requirements. To avoid the applicability of PSD, a minor source permit limits
the company’s net emissions increase from the construction project below the 40 TPY threshold.
To determine the net increase, the Agency considers any decrease in the company’s emissions
that will take place as part of the project (
e.g.
, from taking existing engines out of operation at
the same time). The Agency received Panhandle’s application for a minor source permit and in
turn issued a minor source permit to Panhandle. Panhandle could have appealed the issued
permit but failed to do so,
i.e.
, Panhandle accepted the minor source permit, including the
condition limiting NOx emissions from the four new engines to 461.3 TPY.
 
Panhandle then effectively ignored the NOx emission limit in the permit, while
nevertheless enjoying the benefit of the permit—avoiding the extra compliance costs associated
with PSD. Since 1989, Panhandle has repeatedly exceeded the emission limit in its permit, often
by hundreds of tons of NOx per year. In doing so, Panhandle violated both its permit and the
federal Clean Air Act’s PSD requirements. Panhandle therefore violated the Act. In committing

 
 
3
these major violations, Panhandle failed to take even the most basic steps incumbent upon any
company doing business in Illinois to determine whether it is complying with its permit.
 
In this opinion, the Board first provides this case’s procedural history. The Board then
sets forth its findings of fact. Lastly, the Board discusses the alleged violations, the appropriate
remedy, and the People’s request for costs and attorney fees.
 
PROCEDURAL HISTORY
 
On June 29, 1999, the People filed a two-count complaint against Panhandle for alleged
violations at Glenarm Station. Specifically, count I of the complaint alleges that Panhandle
violated the PSD requirements of Section 165 of the federal Clean Air Act (42 U.S.C. § 7475)
and regulations thereunder (40 C.F.R. §§ 52.21(i) and (j)), thereby violating Sections 9.1(d)(1)
and 9.1(d)(2) of the Act (415 ILCS 5/9.1(d)(1), (2) (2000)). Count II of the complaint alleges
that Panhandle violated its permit limit on NOx emissions, thereby violating Section 9(b) of the
Act (415 ILCS 5/9(b) (2000)). Panhandle filed an answer on July 27, 1999, raising five
affirmative defenses.

The Board’s then Chief Hearing Officer John C. Knittle held a hearing for seven days
over September and November 2000, resulting in just under 1,500 pages of hearing transcript. In
addition, at the parties’ request, the hearing officer incorporated portions of the hearing transcript
from an earlier Board proceeding involving Panhandle’s appeal of an Agency permit decision.

The parties jointly offered 24 hearing exhibits, all of which were admitted. The People
presented seven witnesses. The People offered 42 exhibits, 41 of which were admitted. The
hearing officer excluded from evidence the People’s Exhibit 5, a letter from the United States
Environmental Protection Agency (USEPA) to the Agency. The Board affirmed the hearing
officer’s ruling (
see
People v. Panhandle Eastern Pipe Line Co., PCB 99-191, slip op. at 6 (Feb.
1, 2001)) and later denied the People’s March 12, 2001 motion to reconsider (
see
Panhandle,
PCB 99-191, slip op. at 3 (Oct. 18, 2001)). Panhandle presented nine witnesses. Panhandle
offered 43 exhibits, all of which were admitted. Consistent with its offer at
hearing, Panhandle, on December 12, 2000, filed its parent corporation’s annual reports from
1987 through 1996, all of which were marked as hearing officer exhibits and admitted.

FINDINGS OF FACT
 
Background
 
Panhandle was formed in 1929. Since 1987, Panhandle has been a wholly-owned
subsidiary of several different corporations. In 1987, Panhandle was owned by Panhandle
Eastern Corporation, a publicly owned holding company traded on the New York Stock
Exchange. Panhandle Eastern Corporation changed its name to PanEnergy Corp. in the mid-
90’s. At that point, PanEnergy Corp. was among the United States’ five largest transporters of
natural gas and producers of natural gas liquids. PanEnergy Corp. had 37,000 miles of natural
gas pipeline and provided 12% of the natural gas consumed in the United States. In 1997,
PanEnergy Corp. was merged into Duke Energy Corporation. In 1999, Duke Energy
Corporation sold Panhandle to CMS Energy Corporation, which is the current parent corporation
of Panhandle. Tr. at 668-69; H.O. Exh. 1-10.
 
Panhandle operates an interstate natural gas pipeline that transports natural gas to
customers in Illinois and other Midwestern states. Panhandle’s natural gas pipeline extends from
gas fields in Kansas, Texas, and Oklahoma to the Midwest. Tr. at 29, 605, 827; H.O. Exh. 10.
Due to the great distances that the natural gas is transported, the gas must be recompressed. Tr.
at 682-84. Panhandle uses compressor stations at locations along the pipeline system to ensure
that the gas continues to move through the system and is delivered to customers at serviceable
pressures.
Id.
Panhandle has five compressor stations in Illinois. Tr. at 744. One of those
compressor stations, Glenarm Station, is in Glenarm, Sangamon County. Glenarm Station is in a
rural, lightly populated area and has operated for over 60 years. Tr. at 28, 605-06. The
compressor engines at Glenarm Station emit NOx into the air when they burn fuel (natural gas).
Tr. at 627, 686; Ans. at 3.
 
Air Permitting
 
 
In 1987, Glenarm Station had 15 compressor engines (engines 1101-1115). Tr. at 32-33,
608-13. In September 1987, Panhandle filed with the Agency an application for a construction
permit to replace 12 engines (engines 1101-1112), which were 41 to 56 years old, with four new
engines (engines 1116-1119).
5
Panhandle sought to avoid PSD applicability by offsetting new

The People’s first brief is cited as “People Br. at _.” Panhandle’s response brief is cited as
“Pan. Br. at _.” The People’s reply brief is cited as “Reply Br. at _.”
5
The parties and the Board refer to these four engines as “new” because they were new to
Glenarm Station. Panhandle purchased engines 1116 and 1117, which had been used at a

 
5
NOx emissions from adding engines 1116-1119 with the decreased NOx emissions from retiring
engines 1101-1112. Tr. at 544, 553, 606-07, 612-13, 627, 660, 675-76, 803; Pan. Exh. 1, 2.
Engines 1116 and 1117 were not equipped with emission controls for NOx. Tr. at 620. Engines
1118 and 1119 had been equipped with an early version of “Clean Burn” emission control
technology before arriving at Glenarm Station. “Clean Burn” is the name for this pre-
combustion chamber technology made by Cooper-Bessemer Corporation. Tr. at 684-87.
Panhandle undertook the construction project to modernize its operations—add more efficient
engines and remove older engines that required more maintenance. Tr. at 613, 651-52; Pan. Exh.
2, 3. The construction project at Glenarm Station cost Panhandle approximately $15 to $20
million. Tr. at 639.
  
During the permit application process, Panhandle provided the Agency with data from
1987 on how much fuel engines 1101-1112 used and how many hours they operated. Based on
this data, the Agency calculated that the 12 engines emitted NOx at a rate of 421.4 TPY. Tr. at
100-01, 555-56, 565-66; Pan. Exh. 4; Stip. Exh. 6. To arrive at the 421.4 TPY figure, the
Agency relied on a fuel-based emission factor
6
(3,400 pounds/million cubic feet) in USEPA’s
September 1985 edition of AP-42, “Compilation of Air Pollutant Emission Factors for Stationary
Sources.” Tr. at 30-31, 51, 101, 564-66, 594-95, 1104-05; Pan. Exh. 29; Stip. Exh. 6.
 
In February 1988, the Agency issued Panhandle a minor source permit for the
construction project. Stip. Exh. 1. The permit included an emission limit of 461.3 TPY of NOx
applicable to the four new engines.
Id.
The permit stated that the 461.3 TPY limit was based on
(1) standard emission factors; (2) fuel use from the most recent one year period (
i.e.
, a credit for
decreased emissions of 421.4 TPY, calculated using the 1987 data for engines 1101-1112); and
(3) an allowed emissions increase from the modification of 39.9 TPY. The permit also stated
that the NOx emission limit was necessary to avoid the applicability of PSD. Stip. Exh. 1, 6
.
    
 
The Agency set the 461.3 TPY emission limit to ensure that the four replacement engines
would not result in a net increase in NOx emissions of 40 TPY or more over the 1987 emissions.
The limit was designed to prevent the construction project from being a “major modification”
under PSD rules, thus allowing Panhandle to avoid PSD requirements. Tr. at 48; Stip. Exh. 1, 6.
The construction permit also required Panhandle to keep records on the hours of operation and
the fuel use for each of the four new engines. Tr. at 86; Stip. Exh. 1.
 
The Agency set forth all of these requirements in the construction permit’s three special
conditions:
 
Tenneco Chemical Company facility in Texas, and brought engines 1118 and 1119 to Glenarm
Station from another Panhandle facility, Hugoton Station in Kansas. Tr. at 617, 619-20, 685-86.

An “emission factor” is the “relationship between the amount of pollution produced and the
amount of raw material processed. For example, an emission factor for a blast furnace making
iron would be the number of pounds of particulates per ton of raw materials.” USEPA, Terms of
Environment (last modified May 13, 1998) http://www.epa.gov/OCEPAterms/eterms.html.

1. This permit is issued based upon the replacement of ten Cooper
Compressors and two Clark Compressors with four new Cooper
Compressors. The overall increase in NOx emissions from the
replacement will not exceed 39.9 tons per year. This condition is
necessary to avoid applicability of 40 CFR 52.21, Rules for Prevention of
Significant Deterioration (PSD).
 
2. NOx emissions from the four new compressors shall not exceed 461.3 tons
per year. This limit is based upon [emission] rates calculated from
standard emission factors, the gas usage from the most recent one year
period and the allowed increase of 39.9 tons per year.
 
3. a. The permittee shall keep records of the hours of operation and the gas usage of
each of the new compressor engines.
 
b. These records shall be kept for two years and be available to Agency
inspectors upon request. Stip. Exh. 1.
 
Panhandle completed the construction project in 1988, leaving Glenarm Station with a
total of seven compressor engines (1113-1119), which are the same engines there today. Tr. at
683, 1094. Panhandle applied for an operating permit for the four new engines in July 1988.
Pan. Exh. 5. The Agency issued an operating permit to Panhandle in August 1988. The Agency
issued Panhandle renewed operating permits in September 1989, June 1990, and July 1991. The
most recent permit included an expiration date of June 26, 1996. Each of the operating permits
had the same three special conditions (above) as were in the construction permit. Tr. at 102-03,
580, 584-90; Stip. Exh. 2-5. Panhandle did not appeal the Agency’s 1988 construction permit
decision. Nor did Panhandle appeal any of the four subsequent Agency decisions to issue
operating permits for the four engines.
 
None of the permits specified a limit on hours of operation or fuel use. Tr. at 147, 575;
Stip. Exh. 1-5. Imposing an annual emissions limit in a permit, coupled with recordkeeping
requirements, was consistent with the Agency’s practice for restricting emissions below PSD
levels. Tr. at 102, 138-43; Incorp. Tr. at 361-62. Panhandle kept records of the hours of
operation and the fuel use for the four new engines. Pan. Exh. 7-13. The amount of NOx that a
compressor engine emits in a year can be calculated using a standard emission factor and data on
the engine’s hours of operation or the engine’s fuel use. Tr. at 29-30, 86-89, 140-41, 151-52,
485-87, 509-10, 560, 693, 746-47.
 
Annual Emission Reports and Inspections
 
Panhandle submitted to the Agency annual emission reports, which showed total NOx
emissions annually from Glenarm Station. Before the annual emission report filed in May 1995,
these reports did not provide information on emissions from each engine individually or
information on the total emissions from engines 1116-1119 collectively. To prepare the annual
reports, Panhandle staff calculated the emissions from each of the seven engines using a standard

 
7
emission factor and hours of operation data. Tr. at 58, 91-93, 145-46, 691-97, 784-85, 790-94;
Pan. Exh. 14; Stip. Exh. 9-16.
 
Panhandle employees in Houston, Texas responsible for calculating and reporting
emissions knew of the amounts of NOx being emitted from the Glenarm Station engines. The
evidence in the record, however, does not demonstrate that any of those persons knew of the
461.3 TPY permit limit before the Agency notified Panhandle in 1996 of excess emissions.
Panhandle employees who operated Glenarm Station knew of the permit limit. The evidence in
the record, however, does not demonstrate that any of those persons knew how much NOx was
being emitted before the Agency notified Panhandle in 1996 of excess emissions. The only
Panhandle corporate officer to testify about NOx emissions was Mr. John Alholm, a vice
president of engineering who retired in January 1993. Mr. Alholm oversaw the 1988 Glenarm
Station construction project. While he was with Panhandle, he apparently had no knowledge that
the NOx emissions exceeded a permit limit. Tr. at 602-04, 616-22, 635-36, 656, 659, 671, 691-
99, 702, 704, 707-11, 747-48, 768-70, 791, 798-99, 1215; Pan. Exh. 14, 21; Pan. Br. at 2-3.
 
The Agency inspected Glenarm Station annually. The Agency’s inspection reports found
no violations regarding the four new engines until 1996. During or after the inspections,
Panhandle provided its records of fuel use and hours of operations to the Agency. Beginning at
least with 1991 operations, the hours of operation data was provided for each of the seven
compressor engines individually, while total fuel use data was provided for all seven engines
collectively. Before its 1996 inspection, the Agency did not use this data or the data in the
annual emission reports to assess whether NOx emissions from engines 1116-1119 might be
exceeding the permit limit. Tr. at 31, 35-42, 49, 58, 64-66, 75-77, 84-91, 94-95, 482-84, 492-
520, 528-31; Pan. Exh. 7-12; Stip. Exh. 7.
 
On August 19, 1996, the Agency inspected Glenarm Station. Tr. at 42-43; Stip. Exh. 17.
Because Panhandle had filed a permit application under Title V of the federal Clean Air Act
Amendments of 1990, the Agency’s 1996 inspection of Glenarm Station was more
comprehensive than its prior inspections. The inspection included review of an annual emission
report and the Title V permit application.
7
Tr. at 43-44, 56-58, 90-92; Stip. Exh. 7, 17.
Panhandle’s data on 1995 operations provided both fuel use and hours of operation for each of
the seven engines individually. To calculate 1995 NOx emissions from engines 1116-1119, the
Agency used the data from Panhandle on fuel use for the four engines, and a standard fuel-based
emission factor from USEPA’s 1995 edition of AP-42. Tr. at 29-30, 49-51, 54-56; Pan. Exh. 13.
This calculation showed 1995 NOx emissions from the four engines exceeded the 461.3 TPY
limit. Tr. at 49-52, 54-58; Stip. Exh. 17 at 0020, 0034.
 
7
Title V of the federal Clean Air Act Amendments of 1990 (42 U.S.C. §§ 7661-7661f) ushered
in the Clean Air Act Permit Program (CAAPP). A CAAPP permit is designed to be a
comprehensive statement of all air pollution obligations that apply to a facility. In Illinois, the
General Assembly added the CAAPP to the Act at Section 39.5 (415 ILCS 5/39.5 (2000)). The
Agency has codified the CAAPP permit application process (35 Ill. Adm. Code 270) and the
Board has codified the procedures to appeal the Agency’s CAAPP permit determinations (35 Ill.
Adm. Code 105.300-105.304).

 
 
8
The Agency contacted Panhandle later in 1996 to express concern about NOx emissions
exceeding the permit limit. Tr. at 703-04, 706. After that, Panhandle in 1996 recognized that it
was exceeding the 461.3 TPY permit limit and expressed concern to the Agency over how the
Agency calculated the limit. Tr. at 712-14; Pan. Exh. 6.
 
Panhandle admits that NOx emissions from engines 1116-1119 at Glenarm Station
exceeded the 461.3 TPY limit from 1989 through 1998. Ans. at 14. Using a fuel-based emission
factor from USEPA’s 1985 edition of AP-42 (which the Agency used to set the permit limit of
461.3 TPY), Panhandle calculated the following NOx emissions from engines 1116-1119 in
TPY:
 
1989 686.26
1990 703.11
1991 747.70
1992 659.99
1993 706.55
1994 800.28
1995 1014.93
1996 1173.69
1997 911.57
1998 550.59
 
Pan. Exh. 28, App. B, PAN01706.
 
Violation Notice and Subsequent Events
 
On March 20, 1997, the Agency issued a violation notice to Panhandle based on its
determination that the four new engines at Glenarm Station had violated the permitted annual
NOx emission limit of 461.3 TPY. Tr. at 59; Stip. Exh. 20. In April 1997, representatives of the
Agency and Panhandle met to discuss the violation notice. Tr. at 125, 719-24. In May 1997,
Panhandle responded to the violation notice by submitting to the Agency a compliance
commitment agreement (CCA), along with a construction permit application. Tr. at 63; Incorp.
Tr. at 331; Stip. Exh. 22. Panhandle implemented an “environmental dispatch” program at
Glenarm Station, under which Panhandle reduced emissions from engines 1116-1119 by running
the older engines (1113-1115) first. Tr. at 727-29, 735; Stip. Exh. 22. The Agency rejected the
CCA in June 1997, and issued a notice of intent to pursue legal action in November 1997. Stip.
Exh. 23, 24.
 
In the May 1997 construction permit application, Panhandle sought to increase the PSD
avoidance limit of 461.3 TPY in its minor source permit, and to install “Clean Burn” emissions
controls on engines 1116 and 1117, the two engines out of the four new engines that had no
emission controls. Stip. Exh. 22. In June 1997, the Agency responded to the construction permit
application by issuing a notice that the application was incomplete. The Agency’s notice stated
that the application failed to demonstrate Panhandle’s compliance with PSD requirements. Tr. at
108-09, 729-730; Incorp. Tr. at 333; People Exh. 2. Panhandle submitted additional information,

 
9
and twice proposed revised PSD avoidance limits. Based on recalculating annual NOx
emissions from retired engines 1101-1112 using data from 1985 and 1986, Panhandle requested
to increase its PSD avoidance limit from 461.3 TPY to 560.94 TPY, then later sought to increase
the NOx limit to 729.08 TPY. Incorp. Tr
.
at 303, 305-16, 725; People Exh. 3. In December
1997, the Agency denied Panhandle’s permit application because Panhandle failed to
demonstrate that it would not violate PSD. Tr. at 732; Incorp. Tr
.
at 316.
 
In January 1998, Panhandle filed with the Board a petition to review the Agency’s
decision denying the permit application. The Board affirmed the Agency’s decision in January
1999, and Panhandle appealed the Board’s decision. Tr. at 732. The Fourth District Appellate
Court affirmed the Board’s decision in June 2000.

In August 1999, Panhandle submitted a PSD permit application to the Agency. In its
application, Panhandle proposed to add “Clean Burn” emission control to engines 1116 and 1117
and to enhance the emission controls already on engines 1118 and 1119. Tr. at 732-34. The
Agency has not taken final action on Panhandle’s PSD permit application. Tr. at 734.
 
DISCUSSION
 
Below the Board first discusses the violations that the People have alleged. The Board
then discusses each of the five alleged affirmative defenses that Panhandle has raised. After
ruling on whether Panhandle has violated the Act, the Board, if necessary, will turn to the
appropriate remedy and the People’s request for costs and attorney fees.
 
  
Alleged Violations
 
The People allege that Panhandle violated three sections of the Act—Sections 9.1(d)(1),
9.1(d)(2), and 9(b). Sections 9.1(d)(1) and 9.1(d)(2) prohibit persons from violating PSD
requirements under the federal Clean Air Act. Section 9(b) prohibits persons from operating in
violation of their air permit conditions.
 
Alleged PSD Violations—Sections 9.1(d)(1) and 9.1(d)(2) of the Act
 
Section 9.1(d)(1) of the Act provides that “[n]o person shall . . . violate any provisions of
Section[] . . . 165 . . . of the Clean Air Act, as now or hereafter amended, or federal regulations
adopted pursuant thereto;”
i.e.
, the federal PSD statutory and regulatory requirements.

415
ILCS 5/9.1(d)(1) (2000). Section 9.1(d)(2) of the Act provides:
8
Section 165 of the federal Clean Air Act provides that “[n]o major emitting facility on which
construction is commenced after August 7, 1977, may be constructed in any area to which this
part [42 U.S.C. § 7470
et seq
.] applies unless—(1) a permit has been issued for such proposed
facility in accordance with this part setting forth emission limitations for such facility which
conform to the requirements of this part; * * * (4) the proposed facility is subject to the best
available control technology for each pollutant subject to regulation under this chapter emitted
from, or which results from, such facility * * * .” 42 U.S.C. § 7475(a)(1), (4).

No person shall *** [c]onstruct, install, modify or operate any equipment,
building, facility, source or installation which is subject to regulation under
Section[] . . . 165 . . . of the Clean Air Act, as now or hereafter amended, except
in compliance with the requirements of such Section[] and federal regulations
adopted pursuant thereto, and no such action shall be undertaken without a
permit granted by the Agency or in violation of any conditions imposed by such
permit. *** 415 ILCS 5/9.1(d)(2) (2000).
 
Whether Panhandle is subject to PSD is therefore central to the alleged violations of
Sections 9.1(d)(1) and 9.1(d)(2) of the Act. The federal Clean Air Act established the PSD
program to prevent significant deterioration of air quality in areas with air quality that meets or
exceeds the National Ambient Air Quality Standards (
i.e.
, “attainment areas”).
See
42 U.S.C. §§
7470-7492. Under Section 165 of the Clean Air Act (42 U.S.C. § 7475), USEPA promulgated
regulations at 42 C.F.R. § 52.21 to implement the PSD program. The Agency administers the
federal PSD program under a delegation agreement with USEPA.
See
46 Fed. Reg. 9580, 9582,
9584 (Jan. 29, 1981).
 
The federal PSD program protects against the degradation of air quality in attainment
areas by imposing various requirements on new and modified major stationary sources of
regulated pollutants. Generally, PSD requirements are imposed upon projects that constitute the
construction of a new “major stationary source” or a “major modification” of an existing major
stationary source.
 
A “major modification” is:
 
any physical change in or change in the method of operation of a major stationary
source that would result in a
significant net emissions increase
of any pollutant
subject to regulation under the [federal Clean Air Act]. 40 C.F.R. § 52.21(b)(2)(i)
(emphasis added).
   
A “net emissions increase” is the sum of (1) any increase in actual emissions from the
physical change or change in the method of operation and (2) any other increases and decreases
in actual emissions that are contemporaneous with the increase from the change. 40 C.F.R. §
52.21(b)(3)(i). The pollutant at issue in this case is NOx. A net emissions increase for NOx is
“significant” if it equals or exceeds 40 TPY. 40 C.F.R. § 52.21(b)(23)(i). Therefore, a major
source that undertakes a major modification (
i.e.
, a change resulting in a net emissions increase
in NOx of 40 TPY or more) is subject to PSD.
 
If a modification is “major,” a PSD permit must be obtained before construction begins.
40 C.F.R. § 52.21(i).
9
Before a PSD permit can be issued, the PSD rules require, among other
9
Section 52.21(i) provides in part: “(i) Review of major stationary sources and major
modifications—Source applicability and exemptions. (1) No stationary source or modification
to which the requirements of paragraphs (j) through (r) of this section apply shall begin actual

 
11
things, an emissions source to demonstrate that it will use BACT to control its emissions. 40
C.F.R. § 52.21(j).
10
BACT means:
 
an emissions limitation . . . based on the maximum degree of reduction for each
pollutant . . . which would be emitted from any proposed major stationary source
or major modification which the Administrator, on a case-by-case basis, taking
into account energy, environmental, and economic impacts and other costs,
determines is achievable for such source or modification through application of
production processes or available methods, systems, and techniques, including
fuel cleaning or treatment or innovative fuel combustion techniques for control of
such pollutant. 40 C.F.R. § 52.21(b)(12).
 
The Agency issued a construction permit to Panhandle in 1988 to take out of operation
12 compressor engines (engines 1101-1112) of the 15 existing engines at Glenarm Station, and
to replace those 12 engines with four new compressor engines (engines 1116-1119). The
construction permit contained an emission limit for NOx that applied only to the four new
compressor engines being added. This NOx limit of 461.3 TPY was designed to ensure that
Panhandle’s construction project would not be a major modification—that is, the construction
project would not result in a net emissions increase of 40 TPY or more of NOx.
 
The Agency’s calculated PSD avoidance limit of 461.3 TPY had two components. First,
because Panhandle was taking 12 engines out of operation, those engines would no longer emit
NOx. Panhandle therefore received a credit for decreasing those emissions. Panhandle provided
data on the engines’ fuel use and hours of operation for 1987. With this data, the Agency
calculated that the 12 engines emitted 421.4 tons of NOx in 1987. Panhandle’s emissions
baseline credit (the amount of the decreased emissions) therefore was 421.4 TPY.
 
Second, the Agency took the 421.4 TPY figure and added a less than “significant”
increase in emissions of 39.9 TPY,
i.e.
, NOx emissions after the change could be no greater than
39.9 TPY more than emissions before the change. These two figures (421.4 TPY and 39.9 TPY)
added up to the NOx permit limit of 461.3 TPY. Accordingly, the permit limit, applicable only
to the four new engines, was designed to ensure that the “net emissions increase” from the 1988
construction without a permit which states that the stationary source or modification would meet
those requirements.” 40 C.F.R. § 52.21(i)(1).
  
10
Section 52.21(j) provides in part: “Control technology review. (1) A major stationary source
or major modification shall meet each applicable emissions limitation under the State
Implementation Plan and each applicable emissions standard and standard of performance under
40 CFR parts 60 and 61. *** (3) A major modification shall apply best available control
technology for each pollutant subject to regulation under the [federal Clean Air Act] for which it
would result in a significant net emissions increase at the source. This requirement applies to
each proposed emissions unit at which a net emissions increase in the pollutant would occur as a
result of a physical change or change in the method of operation in the unit.” 40 C.F.R. §
52.21(j)(1), (3).
 

 
12
construction changes would not be “significant” (
i.e.
, would be less than 40 TPY) and thus that
the project would not be a major modification subject to PSD. The Agency subsequently issued
four operating permits to Panhandle, each of which had the 461.3 TPY limit on NOx emissions.
 
In March 1997, Panhandle received a violation notice from the Agency based on NOx
emissions exceeding the 461.3 TPY limit, which ultimately led to this enforcement action. After
receiving the violation notice, Panhandle applied with the Agency to increase the PSD avoidance
limit,
i.e.
, retain a minor source permit but with a less stringent NOx emission limit. Panhandle
argued that the Agency erred in 1988 when it calculated the 421.4 TPY baseline for the
construction permit. The Agency denied Panhandle’s application. The Board affirmed the
Agency’s denial and, in turn, the Fourth District Appellate Court affirmed the Board’s decision.
See
Panhandle, PCB 98-102,
aff’d sub nom
Panhandle, 314 Ill. App. 3d 296, 734 N.E.2d 18.
 
The People allege that Panhandle emitted NOx from engines 1116-1119 in excess of the
461.3 TPY permit limit, which resulted in a major modification subject to PSD,
i.e.
, a net
emissions increase of 40 TPY or more of NOx. The People assert that, despite Panhandle’s NOx
emissions, Panhandle failed to demonstrate BACT, failed to obtain a PSD permit before
constructing or operating engines 1116-1119, and failed to install BACT. The People allege
that, by these failures, Panhandle violated PSD requirements at Section 165 of the federal Clean
Air Act (42 U.S.C. § 7475) and 40 C.F.R. §§ 52.21(i) and (j), and therefore violated Sections
9.1(d)(1) and 9.1(d)(2) of the Act. Comp. at 7-9.
 
As noted, under the federal Clean Air Act, major modifications cannot be built in
attainment areas without a PSD permit and BACT.
See
42 U.S.C. § 7475(a); 40 C.F.R. §§
52.21(i), (j). Panhandle concedes that its NOx emissions from the four new engines have
consistently exceeded the PSD avoidance limit of 461.3 TPY limit and, as of the start of this
enforcement action, had continued to do so. Panhandle also concedes that it has neither obtained
a PSD permit nor implemented emission controls on the four engines that constitute BACT. The
parties do not dispute that Glenarm Station is a major stationary source for NOx or that the
facility is in an attainment area. Ans. at 9-10 (engines 1101-1115 emitted more than 250 TPY of
NOx);
see
 
also
40 C.F.R. § 52.21(b)(1)(i) (definition of “major stationary source”). The parties,
however,
do
dispute whether Panhandle’s 1988 replacement of the 12 compressor engines with
the four new engines was a “major modification” subject to PSD. Panhandle argues that its
exceedences of the 461.3 TPY NOx limit did not trigger PSD requirements, and that the engines
are a minor source.
 
The “source obligation” regulation of PSD, at 40 C.F.R. § 52.21(r)(4), provides:
 
At such time that a particular source or modification becomes a major stationary
source or major modification solely by virtue of a relaxation in any enforceable
limitation which was established after August 7, 1980, on the capacity of the
source or modification otherwise to emit a pollutant, such as a restriction on hours
of operation, then the requirements [of] paragraphs (j) through (s) of this section
shall apply to the source or modification as though construction had not yet
commenced on the source or modification. 40 C.F.R. § 52.21(r)(4).
 

 
13
At the time it promulgated the PSD rules, USEPA discussed the enforcement options available to
the administering agency when a source exceeds the limit of its PSD avoidance permit, including
the applicability of 40 C.F.R. § 52.21(r)(4):
 
One option is simply to enforce . . . the limitations in the permit . . . with the
result that the source retains its minor status. This is appropriate where,
despite
the permit violations, it appears that the source intends to adhere to the emissions
limitations in the future
. However, [USEPA] retains the right to
enforce the PSD
. . . violation as well
.
 
The second option is to invoke the “source obligation” regulations, e.g., 40 CFR
52.21(r)(4), and treat the source as major by requiring it to obtain a PSD
. . . permit. This course is appropriate where the source, through a change in
business plans, or a
belated realization that its original plans cannot
accommodate the design or operational limitations in that permit, and so exceeds
them
. *** [USEPA] treats the source “as though construction had not yet
commenced” for PSD . . . permitting purposes. 54 Fed. Reg. 27274, 27280 (June
28, 1989) (emphasis added).
 
In Panhandle’s appeal of the Agency’s decision denying it a modified minor source
permit with an increased PSD avoidance limit, the Board found the facts of Panhandle’s case
analogous to the second option that USEPA describes and concluded that PSD had been
triggered.
See
Panhandle, PCB 98-102, slip op. at 15,
aff’d sub nom
Panhandle, 314 Ill. App. 3d
296, 734 N.E.2d 18.
11
However, as the Board stated in that proceeding, because its decision was
made in a permit appeal, it was not binding or
res judicata
in any subsequent enforcement
action.
See
Panhandle, PCB 98-102, slip op. at 7-8 (May 20, 1999).
 
Based on the record before it in this enforcement proceeding, the Board again finds that
the second scenario described in USEPA guidance better characterizes the facts of this case. The
condition in Panhandle’s minor source permit limiting NOx emissions to 461.3 TPY was
designed to ensure that Panhandle would avoid PSD by limiting the net emissions increase of
NOx from the 1988 construction project to 39.9 TPY. The permit stated that this was its
purpose. By meeting this PSD avoidance limit in the permit, Panhandle’s increase in NOx
emissions would not constitute a major modification under PSD because it would be less than the
40 TPY threshold.
 
The first enforcement option described by USEPA provides that an agency may enforce
against the exceedences of the minor source permit, without enforcing PSD, if the source intends
to adhere to the original permit limit. This option does not apply here. Panhandle did not exceed
the PSD avoidance limit in its minor source permit once or twice and then demonstrate a ready
ability to comply with the limit. On the contrary, Panhandle continuously exceeded the PSD
11
The Board also held that the Agency lacked the authority to reconsider its 1988 permit
decision. The Fourth District Appellate Court affirmed the Board’s decision on this ground and
others, making it unnecessary for the court to reach the issue of PSD applicability.
See
 
Panhandle, 314 Ill. App. 3d at 306, 734 N.E.2d at 25.

 
14
avoidance limit for many years and finally sought, not to comply with the limit, but to greatly
increase it. Even under the first enforcement option, however, the administering agency retains
the right to enforce the PSD violation as well. Of course, the Act prohibits both the violation of
PSD and the violation of a minor source permit, and the People allege both types of violations
here.
 
The court in United States v. Louisiana-Pacific Corp., 682 F. Supp. 1122 (D. Colo. 1987)
rejected an emission source’s similar arguments about whether PSD is triggered:
 
[Defendant] fails to account satisfactorily for a source which obtains permits
under another regulatory scheme limiting emissions to 250 TPY or less [the
trigger for being considered a “major stationary source” under PSD] and then
fails
to stay within those limitations
. Clearly if Congress intended that a new source
with the potential to emit 250 TPY should be subject to PSD new source review,
it most certainly intended that a new source which actually emits more than 250
TPY should be subject to the PSD program.
***
[Defendant] contends that [USEPA’s] recourse would be to enforce the “federally
enforceable” limitations in the [minor source] permits [without enforcing PSD].
Under such a scenario, however, [USEPA] would be deprived of the benefit of the
remedies Congress created for a violation of PSD. Additionally, [defendant’s]
contention ignores the obvious answer that if Congress had intended for such a
state of affairs to exist, it would never have enacted the PSD program. Louisiana-
Pacific, 682 F. Supp. at 1133 (emphasis added).
 
Panhandle also asserts that it did not know it was violating the 461.3 TPY NOx limit
until the Agency notified Panhandle after the 1996 inspection. It is well-settled, however, that
knowledge is irrelevant to whether a violation occurred. The Act is “
malum prohibitum
, no
proof of guilty knowledge or
mens rea
is necessary to a finding of guilt.” Meadowlark Farms,
Inc. v. PCB, 17 Ill. App. 3d 851, 861, 308 N.E.2d 829, 836 (5th Dist. 1974);
see also
Freeman
Coal Mining Co. v. PCB, 21 Ill. App. 3d 157, 163, 313 N.E.2d 616, 621 (5th Dist. 1974).
Accordingly, whether Panhandle knew it was violating the Act has no bearing on whether
Panhandle violated the Act.
 
The Board finds that Panhandle’s emissions exceeded its PSD avoidance limit for years.
These exceedences demonstrate that the changes Panhandle made in 1988 increased its
emissions by 40 tons or more per year, and therefore that Panhandle made a major modification
in 1988. As Panhandle concedes, it did not comply with PSD. Panhandle constructed and
operated a major modification without obtaining a PSD permit and without demonstrating or
implementing BACT, in violation of PSD requirements under the federal Clean Air Act. The
Board therefore finds that Panhandle, absent any affirmative defenses (discussed below),
violated Sections 9.1(d)(1) and 9.1(d)(2) of the Act.
 
Alleged Permit Condition Violation—Section 9(b) of the Act
 

 
 
15
The People allege that Panhandle violated Section 9(b) of the Act. Section 9(b) provides
that “[n]o person shall *** operate any equipment [or] facility . . . capable of causing or
contributing to air pollution . . . without a permit granted by the Agency, or in violation of any
conditions imposed by such permit.” 415 ILCS 5/9(b) (2000). The People allege that Panhandle
violated the minor source permit condition limiting NOx emissions to 461.3 TPY and therefore
violated Section 9(b). Comp. at 10-11. Panhandle admits that “the NOx emissions from
compressor engines 1116-1119 at its Glenarm Station exceeded the 461.3 [TPY] NOx limit
beginning with the first full year [1989] the engines operated and continuing every year since.”
Pan. Br. at 1.
 
NOx emissions from the four new engines at Glenarm Station consistently exceeded the
461.3 TPY NOx permit limit. Panhandle’s own calculations show exceedences each year from
1989 through 1998. These calculations reveal that the smallest amount of emissions, taking
place in 1998, exceeded the limit by 89.29 tons, while the largest amount of emissions, taking
place in 1996, exceeded the limit by 712.39 tons. The Board finds it appropriate that, for these
calculations, Panhandle used the same USEPA fuel-based emission factor that the Agency used
to calculate the permit limit of 461.3 TPY. However, using a variety of different emission
factors also revealed year after year of exceedences of the permitted NOx emission limit.
See
,
e.g.
, People Exh. 3 at 0090; Pan. Exh. 28, App. A, PAN01694, App. B, PAN01706; Stip. Exh. 22
at 0182. The Board finds that Panhandle violated the 461.3 TPY NOx permit limit and therefore,
absent any affirmative defenses (discussed below), violated Section 9(b) of the Act.
 
Alleged Affirmative Defenses
 
Panhandle raises five alleged affirmative defenses to the violations alleged by the People.
The first and second alleged affirmative defenses relate to the 461.3 TPY NOx limit itself. The
third, fourth, and fifth alleged affirmative defenses relate to the Agency inspecting Glenarm
Station, renewing Panhandle’s operating permit, and reviewing Panhandle’s annual emission
reports. In the alternative, Panhandle states that if the Board finds that the alleged affirmative
defenses do not preclude enforcement, then the evidence entered to support each defense should
mitigate against a civil penalty. Pan. Br. at 3.
 
First Alleged Affirmative Defense: Denial of Due Process
 
Panhandle claims that the Agency denied it due process by issuing the minor source
permit without first giving Panhandle, and the public, notice and an opportunity to comment on
the 461.3 TPY limit. Panhandle argues that the emissions baseline credit that the Agency
calculated in 1988 was too small. Again, based on 1987 fuel use data for the 12 retired engines,
the Agency calculated a credit of 421.4 TPY, reflecting the decrease in NOx emissions by taking
the 12 engines out of operation. Panhandle argues that 1985 and 1986 were more representative
of how the 12 engines normally operated. Panhandle claims that 1987 was not representative
because warmer weather in 1986 and 1987 limited natural gas use in 1987. Panhandle asserts
that if, in 1988, a draft permit had been issued and subject to notice and comment, “then the
problems with the 461.3 TPY NOx limit . . . would have been discovered.” Pan. Br. at 18-19.
Panhandle argues that the permit limit is therefore invalid and unenforceable.
 

 
16
Special condition No. 1 of Panhandle’s 1988 construction permit stated that the “overall
increase in NOx emissions from the replacement [of compressor engines] will not exceed 39.9
tons per year” and that this “condition is necessary to avoid applicability of 40 CFR 52.21, Rules
for Prevention of Significant Deterioration (PSD).” Stip. Exh. 1. Special condition No. 2 of the
construction permit states that the 461.3 TPY “limit is based upon [emission] rates calculated
from standard emission factors, the gas usage from the most recent one year period and the
allowed increase of 39.9 tons per year.”
Id
. Thus, the minor source permit itself clearly stated
(1) that the NOx limit was 461.3 TPY; (2) that the limit was designed to avoid PSD; and (3) that
the limit was based on 1987 fuel use data for the retired engines.
 
Panhandle intended to avoid PSD by offsetting the new NOx emissions (from adding
engines 1116-1119) with the simultaneous emissions decrease (from taking engines 1101-1112
out of operation). Panhandle knew that the Agency would have to determine the amount of the
emissions decrease to perform this netting calculation. During the permit application process,
Panhandle provided the Agency with fuel use data on the 12 engines being retired. However,
Panhandle provided data not from 1985 and 1986, but rather from 1987. Pan. Exh. 1-4. As the
permit applicant, Panhandle could have provided data from 1985 and 1986 for the Agency to
consider. Panhandle should not be surprised that the Agency used the only data that Panhandle
provided to calculate past emissions from the 12 engines.
 
Moreover, Panhandle’s past NOx emissions exceeded not only its actual permit limit of
461.3 TPY, but also the higher PSD avoidance limit that Panhandle sought in 1997. As noted,
after the Agency issued the violation notice in 1997, Panhandle applied to increase its minor
source permit limit by using a baseline credit based on 1985 and 1986 NOx emissions from the
12 retired engines. In 1997, Panhandle first asked for an increase of the NOx limit to 560.94
TPY, then changed its application and sought an increase to 729.08 TPY. Despite Panhandle’s
concerns over how the Agency arrived at the NOx limit in 1988, Panhandle’s actual NOx
emissions repeatedly exceeded even Panhandle’s later-proposed limits. Nor does Panhandle
explain why its review of a “draft” of the 1988 permit would have been any more strenuous than
its review of the issued construction permit, or the four subsequent operating permits.
 
More importantly, however, for over 30 years, the Act has given permit applicants like
Panhandle the right to appeal Agency permit decisions. Specifically, Section 40(a)(1) of the Act
(415 ILCS 5/40(a)(1) (2000)) affords a permit applicant the opportunity to appeal an Agency
permit decision to the Board within 35 days after the Agency’s decision. Panhandle failed to do
so. By failing to do so, the permit became final and binding. Panhandle cannot now, in an
enforcement proceeding over ten years later, raise challenges to the validity of the permit’s
emission limit based on alleged deficiencies in the permit application process. To hold
otherwise would render the 35-day appeal period of Section 40(a)(1) meaningless.
See
 
Panhandle, 314 Ill. App. 3d at 304, 734 N.E.2d at 24 (having an unlimited time to revise permit
decisions “would render meaningless the review provisions of the Act”).
 
Panhandle’s reliance on Village of Sauget v. PCB, 207 Ill. App. 3d 974, 566 N.E.2d 724
(5th Dist. 1990) for its due process claim is therefore misplaced. In that case, the permit
applicant that raised a due process challenge, unlike Panhandle, timely appealed the Agency’s

 
17
permit decision to the Board and, in turn, timely appealed the Board’s decision to the Appellate
Court. The Board denies Panhandle’s first alleged affirmative defense.
 
The Board’s decision is consistent with Hawaiian Electric Co. v. USEPA, 723 F.2d 1440
(9th Cir. 1984). The Fourth District Appellate Court relied upon Hawaiian Electric when it
affirmed the Board in the Panhandle case involving the Agency’s denial of Panhandle’s request
for a revised minor source permit. In Hawaiian Electric, Hawaiian Electric requested that
USEPA modify Hawaiian Electric’s PSD permit after the time period for Hawaiian Electric to
appeal the original PSD permit had expired. Hawaiian Electric, 723 F.2d at 1441-42, 1445. The
court noted that the legislative intent to “avoid excessive bureaucratic contention” by requiring
USEPA to make permit decisions within a prescribed time period would be frustrated if past
determinations could be routinely challenged
de novo
.
Id
. at 1446. The court stated:
 
[Hawaiian Electric] argues that it is challenging the premises under which the
permit was originally granted and that therefore the application of the major
modification definition in particular and PSD review in general is incorrect. The
policy of finality, which is critical to the administration of a complex technocratic
program, dictates that [Hawaiian Electric’s] argument must fail. Finality is a
particularly important value in air pollution control because of the simultaneous
existence of substantial risk and substantial technical uncertainty.
Id
. at 1445.
 
Second Alleged Affirmative Defense: Permitted Emission Limit is Practicably
Unenforceable
 
Panhandle asserts that the annual NOx limit of 461.3 TPY is “illegal and unenforceable
because the permit did not contain practicably enforceable conditions . . . such as restrictions on
hours of operation or fuel usage . . . .” Pan. Br. at 19. This collateral attack by Panhandle on a
final and valid permit fails as a bar to enforcement for the reasons, articulated above, that
Panhandle’s first alleged affirmative defense must fail. Moreover, contrary to Panhandle’s
assertions, nowhere did the Louisiana-Pacific court hold that minor source permit limits on
actual emissions are unenforceable. In fact, the court acknowledged that such limits
are
 
enforceable.
See
Louisiana-Pacific, 682 F. Supp. at 1133 (referring to minor source permit limits
on actual emissions as “federally enforceable”).
 
Even Panhandle concedes that compliance with an annual emission limit
can
be
verified—a “way to determine compliance with an annual emissions cap is to run calculations
using data on fuel use or hours of operation and an emission factor.” Pan. Br. at 20. This
information was readily available to Panhandle and this record is replete with such calculations.
The minor source permit required Panhandle to keep records of the hours of operation and the
fuel use for each of the four new compressor engines.
 
Not restricting the new engines’ operating hours or fuel use in Panhandle’s permit does
not render the annual emission limit unenforceable. Panhandle could have readily monitored its
compliance with the NOx limit by estimating annual emissions, based on fuel use, hours of
operation, and a standard emission factor. Even if, as Panhandle asserts, the “Glenarm Station
personnel were not familiar with the manner in which NOx emissions could be calculated” (Pan.

 
18
Br. at 20), this is no defense. Moreover, Panhandle concedes that its “employees in Houston
responsible for calculating and reporting emissions to the Agency knew what the NOx emissions
were . . . .” Pan. Br. at 2. To prepare the annual emission reports, Panhandle staff calculated the
emissions from each of the four engines. Panhandle admits that “[s]omeone who could calculate
emissions should have known of the emissions limit.”
Id
. at 3.
  
Finally, Panhandle argues that, because it was retiring 12 “older, dirtier” engines and
replacing them with four more efficient engines, it believed in “good faith” that its 1988
construction project would decrease NOx emissions, not result in a significant net emissions
increase in NOx emissions. Pan. Br. 2, 19. As discussed above, however, the Act is
malum
prohibitum
—whether Panhandle believed it would not violate its permit is irrelevant to whether
Panhandle violated its permit. The Board denies Panhandle’s second alleged affirmative
defense.
      
Third Alleged Affirmative Defense: Waiver or Estoppel
 
Panhandle claims that it reasonably and detrimentally relied on the Agency’s alleged
misrepresentations that Panhandle was in compliance with the NOx emission limit in the PSD
avoidance permit. Pan. Br. at 22. Panhandle argues that it relied on the following:
 
1. The Agency’s annual inspections before 1996 found either “no violation” or a
violation unrelated to the four new engines, even with records of fuel use and
hours of operation provided;
 
2. The Agency’s renewals of the minor source operating permit, the standard for
issuance of which being that the permit applicant had submitted proof to the
Agency that the emission units at issue would not cause a violation of the Act;
and
 
3. The Agency’s failure to take any enforcement action upon receiving annual
emission reports from Panhandle. Pan. Br. at 24.
 
Panhandle states that the Agency, in carrying out these functions, has waived its right to enforce
against Panhandle or should now be estopped from pursuing this enforcement action.
 
The doctrine of waiver applies when a party intentionally relinquishes a known right or
his conduct warrants an inference to relinquish the right.
See
Hartford Accident and Indemnity
Co. v. D.F. Bast, Inc., 56 Ill. App. 3d 960, 962, 372 N.E.2d 829, 831 (1st Dist. 1977); People v.
Douglas Furniture of California, Inc., PCB 97-133, slip op. at 5 (May 1, 1997). The doctrine of
equitable estoppel may be applied when a party reasonably and detrimentally relies on the words
or conduct of another.
See
Brown’s Furniture, Inc. v. Wagner, 171 Ill. 2d 410, 431, 665 N.E.2d

Brewer Trucking, Inc. v. IEPA, PCB 96-250, slip op. at 10 (Mar. 20, 1997). However, the
doctrine “should not be invoked against a public body except under compelling circumstances,
where such invocation would not defeat the operation of public policy.” Gorgees v. Daley, 256
Ill. App. 3d 514, 518, 628 N.E.2d 721, 725 (1st Dist. 1993).

 
19
 
As the Illinois Supreme Court explained:
 
This court’s reluctance to apply the doctrine of estoppel against the State has been
motivated by the concern that doing so may impair the functioning of the State in
the discharge of its government functions, and that valuable public interests may
be jeopardized or lost by the negligence, mistakes or inattention of public
officials. Brown’s Furniture, 171 Ill. 2d at 431-32, 665 N.E.2d at 806,
citing
 
Hickey v. Illinois Central Railroad, 35 Ill. 2d 427, 447-48, 220 N.E.2d 415, 426
(1966);
see also
Chemetco, PCB 96-76, slip op. at 11; White & Brewer Trucking,
PCB 96-250, slip op. at 10.
 
Consistent with this reluctance, a party seeking to estop the government must show that the
government made a misrepresentation with knowledge that the misrepresentation was untrue.
See
Medical Disposal Services, Inc. v. IEPA, 286 Ill. App. 3d 562, 570, 677 N.E.2d 428, 433
(1st Dist. 1997); City of Mendota v. PCB, 161 Ill App. 3d 203, 209,514 N.E.2d 218, 222 (3d
Dist. 1987); Chemetco, PCB 96-76, slip op. at 11; White & Brewer Trucking, PCB 96-250, slip
op. at 10.
 
  
The Board finds that Panhandle has not demonstrated waiver by the State. None of the
Agency’s activities constitute the relinquishment of the People’s right to bring this enforcement
action. Nor do the facts of this case present the “compelling circumstances” necessary for
applying the equitable doctrine of estoppel to bar the government from bringing this enforcement
action. Hickey, 35 Ill. 2d at 448, 220 N.E.2d at 426.
 
“[T]he reluctance of courts to hold governmental bodies estopped to assert their claims is
particularly apparent when the governmental unit is the State.” Hickey, 35 Ill. 2d at 447, 220
N.E.2d at 425. The General Assembly has given the Agency a central role in Illinois’ system of
environmental law. Under the Act, the Agency’s responsibilities include administering the
various air pollution control programs. These programs are a vital part of Illinois’ effort to
“restore, maintain, and enhance the purity of the air of this State in order to protect health,
welfare, property, and the quality of life and to assure that no air contaminants are discharged
into the atmosphere without being given the degree of treatment or control necessary to prevent
pollution.” 415 ILCS 5/8 (2000).
 
Functioning in this critical governmental capacity, the Agency issues permits to, inspects
the facilities of, and receives emissions data from companies all over Illinois.
See
415 ILCS
5/4(d), (g), (l) (2000). However, permit applications are considered by the Agency based on the
information that the applying companies provide. Inspection reports finding “no violation”
mean only that those particular Agency inspectors did not uncover a problem at a facility on
those specific occasions. Thousands of annual emission reports are received by the Agency
every year. None of these Agency functions insulate companies from liability for emitting
excess pollutants into the air.
 
Companies cannot simply sit back and wait to see if they will be caught by the Agency.
For Illinois’ system of environmental programs to be effective, self-policing is required of

 
20
industry. Here, when Panhandle became subject to Title V of the federal Clean Air Act
Amendments of 1990, the Agency conducted a more comprehensive inspection and found the
NOx emission problem. To exonerate Panhandle of liability for the pollutants it has emitted for
years in violation of our air pollution control laws because the Agency, acting in good faith, did
not discover the company’s problems sooner would surely “impair the functioning of the State in
the discharge of its governmental functions” and jeopardize “valuable public interests.” Hickey,
35 Ill. 2d at 447, 220 N.E.2d at 426.
 
The Board finds that the Agency’s execution of these basic governmental functions do
not absolve Panhandle of its statutory obligation to determine, on its own, whether it is
complying with its permit. As discussed above, Panhandle could have readily made that
determination.
See
Hickey, 35 Ill. 2d at 447, 220 N.E.2d at 425 (1966) (party alleging estoppel
must have “no knowledge or convenient means of knowing the true facts”). It is the
responsibility of companies doing business in Illinois to determine whether they are complying
with Illinois’ environmental laws. Panhandle’s reliance on Agency permit renewals and
inspections as the
sole
means by which Panhandle determined its compliance was unreasonable.
See
Chemetco, Inc., PCB 96-76, slip op. at 10; White & Brewer, PCB 96-250, slip op. at 10.
Moreover, Panhandle has made no showing that any Agency personnel made misrepresentations
to Panhandle with the knowledge that they were untrue. The Board denies Panhandle’s third
alleged affirmative defense.
Fourth Alleged Affirmative Defense: Unreasonable Delay by the Agency
 
 
Laches
.
Panhandle claims that the Agency’s “inaction over the course of many years”
warrant applying the doctrine of
laches
to bar this enforcement action. Pan. Br. at 25.
Panhandle claims that the Agency failed to exercise due diligence in the same three contexts for
which Panhandle claims waiver and estoppel: (1) annually inspecting Glenarm Station; (2)
renewing Panhandle’s minor source operating permit; and (3) reviewing annual emission reports
from Panhandle. Panhandle asserts that the Agency, over an eight-year period, “failed to
discover that operation of engines 1116-1119 caused NOx emissions to exceed the annual NOx
limit” resulting in the “undue delay” of this enforcement action.
Id
. at 26. Panhandle argues that
the Agency should have discovered the exceedence of the 461.3 TPY limit years before 1996
because Panhandle had supplied the Agency with “all the information necessary to determine
whether Panhandle was in violation of its permit.”
Id.
 
Laches
is an equitable doctrine which precludes the assertion of a claim by a litigant
whose unreasonable delay in raising that claim has prejudiced the opposing party.” Tully v.
Illinois, 143 Ill. 2d 425, 432, 574 N.E.2d 659, 662 (1991);
see also
City of Rochelle v. Suski,
206 Ill. App. 3d 497, 501, 564 N.E.2d 933, 936 (2d Dist. 1990). There are two principal
elements of
laches
: (1) lack of due diligence by the party asserting the claim; and (2) prejudice
to the opposing party as a result of the delay.
See
Van Milligan v. Board of Fire & Police
Commissioners, 158 Ill. 2d 84, 89, 630 N.E.2d 830, 833 (1994); Tully, 143 Ill. 2d at 432, 574
N.E.2d at 662; People v. State Oil Co., PCB 97-103, slip op. at 2 (May 18, 2000). As with the
equitable doctrine of estoppel, applying
laches
against the government is disfavored and can
apply against the State functioning in its governmental capacity only in compelling
circumstances.
See
Hickey, 35 Ill. 2d at 447-48, 220 N.E.2d at 425-26.

 
21
  
Panhandle has not demonstrated that the Agency “knowingly slept on [its] rights to the
detriment of [Panhandle].” Tully, 143 Ill. 2d at 432, 574 N.E.2d at 662. In addition, as noted,
Panhandle admits that its Houston staff knew of the amounts of NOx being emitted from engines
1116-1119 while its Glenarm Station staff knew of the 461.3 TPY permit limit. Pan. Br. at 2.
This record does not show that any alleged delay in the Agency’s discovery of violations
prejudiced Panhandle so as to preclude the People’s enforcement action. Panhandle’s failure to
recognize that its emissions violated its permit was not caused by the time it took the Agency to
discover the violations, but rather by the deficient internal communications of Panhandle, which
showed a flagrant disregard of its permit obligation.
 
Had Panhandle diligently monitored its compliance, it could have addressed the
exceedences long before the Agency became aware of them. For that matter, if Panhandle had
merely reviewed its permit when it received it in 1988, Panhandle could have avoided these
violations. The person who oversaw the 1988 construction project for Panhandle, Mr. John
Alholm, testified about the importance of the 461.3 TPY limit in the 1988 permit:
 
Q. What does a 461.3 ton per year NOx emission limit mean to you?
* * *
A. *** [I]f that is not enough tonnage of NOx emissions from these units that
would allow them to operate at a level that they were intended to operate
at, that would have been, in effect, a show stopper.
 
Q. What do you mean by show stopper?
   
A. We would have gone back to find out how many hours of operation that
would have represented. If that was not close to 8,000 hours a year for
each one of these units, then that would have been in question as to why
not and should we go ahead with the project. Tr. at 632-33.
 
Accordingly, before it received its 1988 construction permit, Panhandle knew the number of
hours that it intended to operate engines 1116-1119. Yet Panhandle could not operate these four
engines for more than approximately half of that time and stay under the 461.3 TPY limit. Tr. at
707. With its intended hours of operation and a standard emission factor, Panhandle could have
calculated the tons of NOx emissions per year that it believed it needed, and, at a minimum,
compared that figure to the 461.3 TPY limit when it received the permit. Somehow Panhandle
failed to do that even though the limit was so critical to a $15 to $20 million construction project.
 
As with the alleged defense of estoppel, the Board finds that Panhandle failed to prove
the compelling circumstances required to apply the equitable doctrine of
laches
against the
government. The Board denies Panhandle’s alleged affirmative defense based on
laches
.
  
 
The 180-Day Time Period of Section 31(a)(1) of the Act.
Panhandle alleges that the
Agency failed to comply with the 180-day time period of Section 31(a) of the Act. Section
31(a)(1) states in part:
 

 
22
Within 180 days of becoming aware of an alleged violation of the Act or any rule
adopted under the Act or of a permit granted by the Agency or condition of the
permit, the Agency shall issue and serve, by certified mail, upon the person
complained against a written notice informing that person that the Agency has
evidence of the alleged violation. 415 ILCS 5/31(a)(1) (2000).
 
Panhandle alleges that the Agency failed to issue a violation notice to Panhandle within 180 days
after becoming aware of Panhandle’s exceedence of the 461.3 TPY permit limit. The Agency
inspected Glenarm Station on August 19, 1996, and issued the violation notice to Panhandle on
March 20, 1997—213 days after the inspection.
 
Section 31 of the Act provides all respondents in State enforcement actions with notice
and opportunity to meet with the Agency before the Agency refers the matter to the Attorney
General for enforcement. The Board has held that the 180-day time period of Section 31(a)(1) is
not a statute of limitations.
See
People v. John Crane, Inc. PCB 01-76, slip op. at 5
(May 17, 2001). In Crane, the Board also held that “[w]hile the substance of the Section 31 pre-
referral process is mandatory, the 180-day time period of Section 31(a)(1) is directory.”
Id.
at 6.
 
Panhandle does not allege that the Agency failed to issue a violation notice or to meet
with Panhandle to discuss the violation notice before referring the matter to the Attorney
General. In fact, the Agency afforded Panhandle this process. Panhandle alleges only that the
Agency did not issue the violation notice within the 180-day time period of Section 31(a)(1).
However, even if the Agency did not issue the violation notice within the directory 180-day
period, the Board is not thereby divested of jurisdiction to hear this complaint.
See
Crane, PCB
01-76, slip op. at 6. The Board denies Panhandle’s alleged affirmative defense based on the 180-
day time period of Section 31(a)(1).
 
Fifth Alleged Affirmative Defense: Statute of Limitations
 
Panhandle asks the Board to apply the Code of Civil Procedure’s five-year limitation on
civil actions (735 ILCS 5/13-205 (2000)) to this enforcement action. Panhandle states that the
alleged violations “accrued over ten years before” the People filed the complaint. Pan. Br. at 29.
As with the third and fourth alleged affirmative defenses, Panhandle again asserts that the
Agency failed to diligently assess “the compliance status of the Glenarm Station from 1989 until
1996.”
Id.
Panhandle argues that the Agency’s “egregious lack of diligence” warrants a
departure from the “general rule that the statute of limitations does not apply where the State
brings an action involving public rights.”
Id.
   
 
  
Panhandle also argues that this enforcement action is not in pursuit of the “public’s right
to a clean environment” because it really seeks only civil penalties. Pan. Br. at 30. According to
Panhandle, the “installation of emission controls, and not the assessment of civil penalties, will
help to ensure a healthful environment.”
Id.
at 29. Panhandle filed a PSD permit with the
Agency in August 1999 to install emission controls on the two uncontrolled engines (1116 and
1117) and to augment controls on engines 1118 and 1119. Panhandle asserts that the only basis
for which the People seek an order from the Board that Panhandle cease and desist from further
violations is that the Agency has not yet taken final action on the PSD permit application.

 
 
23
 
The Board does not find any merit in Panhandle’s claims. It is well-settled that no statute
of limitations applies to enforcement actions brought by the People pursuant to Section 31 of the
Act (415 ILCS 5/31 (2000)), as is the case here.
See
,
e.g.
, Crane, PCB 01-76, slip op. at 5.
Moreover, the People are seeking “to protect the public’s right to a clean environment.” Pielet
Bros. Trading, Inc. v. PCB, 110 Ill. App. 3d 752, 758, 442 N.E.2d 1374, 1379 (5th Dist. 1982).
Besides the purposes of PSD under the federal Clean Air Act to ensure that air quality in
attainment areas does not suffer, the General Assemble found in Section 8 of the Act that:
 
pollution of the air of this State constitutes a menace to public health and welfare,
creates public nuisances, adds to cleaning costs, accelerates the deterioration of
materials, adversely affects agriculture, business, industry, recreation, climate,
and visibility, depresses property values, and offends the senses. 415 ILCS 5/8
(2000).
 
That Panhandle filed a PSD permit application to install emission controls is no
assurance of compliance with PSD. Panhandle’s proposed control technology and emission rate
may not be the best available control technology or BACT. In addition, Panhandle may not
make the requisite ambient air quality impact demonstration under PSD. Panhandle also could
simply withdraw its PSD application. The People seek a Board order requiring that Panhandle
cease and desist from further violating PSD requirements, as well as the 461.3 TPY limit in the
permit. Comp. at 9, 11. Moreover, Panhandle cites no authority for its proposition that civil
penalties do not further the public’s right to a clean environment. The People seek civil penalties
for the Environmental Protection Trust Fund.
See
415 ILCS 5/42(a) (2000). Civil penalties can
also serve to deter further violations and enhance voluntary compliance by a respondent and
those similarly situated.
See
415 ILCS 5/42(h)(4) (2000). The Board finds that this enforcement
action seeks to further the public’s right to a clean environment and is not subject to the Code of
Civil Procedure’s five-year limitation on actions.
  
  
Remedy
 
Having found that none of the alleged affirmative defenses bar enforcement and that
Panhandle violated Sections 9.1(d)(1), 9.1(d)(2), and 9(b) of the Act, the Board turns to the
appropriate remedy for these violations. The People request that the Board order Panhandle to
cease and desist from further violations and impose a $2,218,759 civil penalty on Panhandle.
People Br. at 138. Panhandle argues that the Board should assess no civil penalty.
Alternatively, Panhandle argues that because it has not benefited economically from the
violations, any civil penalty should be no greater than $160,000. Pan. Br. at 3, 89-90. The
maximum possible penalty authorized by the Act easily exceeds $60 million.
See
415 ILCS
5/42(a) (2000).
 
Panhandle’s minor source permit limit on NOx emissions of 461.3 TPY has special
significance. Like any air permit condition, the violation of the NOx limit is a violation of
Section 9(b) of the Act, which prohibits the violation of air permit conditions. However,
Panhandle’s permitted NOx limit was also designed so that Panhandle could avoid PSD and its
associated expenses. Compliance with the limit of 461.3 TPY would ensure that Panhandle’s

 
24
1988 construction project, adding the four new engines, was not a “major modification” under
PSD. Any “net emissions increase” in NOx resulting from the modification would not be
“significant” because the increase would be less than 40 TPY. By exceeding that limit as it has,
Panhandle not only violated a permit condition, it triggered the applicability of PSD. Its 1988
construction project was a “major modification,” which Panhandle built and operated without a
PSD permit or BACT, in violation of PSD and thus in violation of Sections 9.1(d)(1) and
9.1(d)(2) of the Act.
  
In determining an appropriate remedy for these violations, the Board must consider the
factors set forth in Section 33(c) of the Act (415 ILCS 5/33(c) (2000)). In determining an
appropriate civil penalty component of that remedy, the Board is authorized to consider the
factors set forth in Section 42(h) of the Act (415 ILCS 5/42(h) (2000)). Before making its
finding on the appropriate remedy, below the Board applies each of the factors of Sections 33(c)
and 42(h) to the record in this case, including evidence introduced on the alleged affirmative
defenses.
 
Section 33(c) of the Act
 
To determine an appropriate remedy, including civil penalty, the Board considers the
factors set forth in Section 33(c) of the Act. Section 33(c) provides in part:
 
(c) In making its orders and determinations, the Board shall take into
consideration all the facts and circumstances bearing upon the
reasonableness of the emissions, discharges or deposits involved
including, but not limited to:
 
(i) the character and degree of injury to, or interference with the
protection of the health, general welfare and physical property of
the people;
 
(ii) the social and economic value of the pollution source;
 
(iii) the suitability or unsuitability of the pollution source to the area in
which it is located, including the question of priority of location in
the area involved;
 
(iv) the technical practicability and economic reasonableness of
reducing or eliminating the emissions, discharges or deposits
resulting from such pollution source; and
 
(v) any subsequent compliance. 415 ILCS 5/33(c) (2000).
 
The Board considers each of these factors in turn.
 
 
Character and Degree of Injury or Interference.
The People state that:
 

 
25
Despite obtaining a PSD avoidance permit for a purported minor source
construction project, Panhandle operated the compressor engines at emission
levels that made the project a major modification. By doing so . . . Panhandle
prevented the [Agency] from fulfilling its role as the delegated PSD authority in
Illinois. People Br. at 53-54.
 
Panhandle states that the record contains no evidence that the excess NOx emissions
“were of a character and degree to interfere with the protection and heath, general welfare or
property of the people,” and that “Panhandle’s NOx emissions in excess of the 461.3 TPY permit
limit had minimal impact, if any, on the air quality of Sangamon County.” Pan. Br. at 34.
Panhandle then explains that the NOx emissions from engines 1116-1119 comprised only a small
fraction of the total NOx emissions from Illinois in general and Sangamon County in particular.
Panhandle also presented Mr. Bruce Dumdei with the environmental engineering firm of URS
Corporation, who testified that emissions from engines 1116-1119 “are not significant compared
to the overall emissions from Sangamon County and other sources that contribute to Sangamon
County’s annual air quality for [NOx].” Tr. at 1170-71.
 
Panhandle’s arguments miss the mark. Regardless of the fact that Panhandle’s excess
emissions have not resulted in Sangamon County losing its attainment status, Panhandle has built
and operated a major modification without providing any of the environmental protections that
Congress intended. NOx is a pollutant that can contribute to a violation of the National Ambient
Air Quality Standard for nitrogen dioxide, and can result in acid rain and ozone formation, all of
which threaten health. That is why NOx was designated a pollutant under the federal Clean Air
Act and why there is an extensive, federally-mandated permitting process for major NOx
emitters.
 
Complainants do not have to prove that an air quality standard has been violated or that
someone has experienced health problems for the Board to weigh this Section 33(c) factor
against a respondent that has unlawfully emitted pollutants into our air. The General Assembly
recognized that an effective environmental protection system must prohibit even threats of air
pollution.
See
415 ILCS 5/9(a) (2000) (“No person shall . . . [c]ause or
threaten
or allow the
discharge or emission of any contaminant into the environment in any State so as to cause
or
tend to cause
air pollution in Illinois . . . .”) (emphasis added). Panhandle’s NOx emissions
exceeded the 461.3 TPY limit each year for at least ten years by very large margins, typically by
several hundred tons of NOx each year. For example, NOx emissions from the four engines in
1995 and 1996 were, respectively, 1014.93 tons and 1173.69 tons, more than doubling the limit
in the minor source permit.
 
Nor do Panhandle’s violations occur in a vacuum. As Panhandle points out, it is not the
only source permitted to emit NOx in Sangamon County. The cumulative effect of multiple
violations by Panhandle and other sources could endanger the air quality of Sangamon County.
Further, excess NOx emissions from sources across Illinois also can negatively impact ozone
levels in the Chicago and East St.Louis ozone nonattainment areas. The General Assembly also
recognized that air pollution can result from many sources when it prohibited contaminant
emissions causing or tending to cause air pollution “either alone or in combination with
contaminants from other sources.”
See
415 ILCS 5/9(a) (2000).

 
26
 
Moreover, the Agency issued, and Panhandle accepted, a PSD avoidance permit, the
purpose of which was to allow Panhandle to increase its NOx emissions slightly, without having
to undertake the costly and time-consuming PSD review. Therefore, when it applied for a minor
source permit, Panhandle would have avoided performing an expensive analysis of the impact of
its NOx emissions on ambient air quality. The absence of such evidence in the record now is of
no aid to Panhandle. Panhandle’s failure to comply with its PSD avoidance permit over the
course of at least 10 years defeats the purpose of the PSD program—to protect against the
degradation of air quality in attainment areas. Panhandle’s noncompliance jeopardizes the
Agency’s ability to effectively administer the federally-delegated PSD program and thereby
seriously interferes with the “
protection
of the health . . . of the people.” 415 ILCS 5/33(c)(i)
(2000) (emphasis added). The Board weighs this Section 33(c) factor against Panhandle.
 
 
Social and Economic Value of Pollution Source.
The People do not dispute that
Glenarm Station has social and economic value. Panhandle maintains that engines 1116-1119
play an important role in supplying natural gas to users in Illinois and elsewhere. The Board
weighs this Section 33(c) factor in favor of Panhandle.
 
 
Suitability of Pollution Source.
Glenarm Station has operated for more than 60 years.
The area of Sangamon County in which Glenarm Station is located is rural and lightly populated.
The Board finds that Glenarm Station is suitably located and weighs this Section 33(c) in favor
of Panhandle.
  
 
Technical Practicability and Economic Reasonableness of Compliance.
Panhandle
concedes that it was technically practicable and economically reasonable to install emission
control technology on the engines when they were installed in 1988. However, Panhandle
emphasizes that it is more costly now to add control technology to engines that are fully
assembled and operational. Pan. Br. at 39.
 
The Board finds that, although more complex and expensive now than in 1988, installing
emission control technology now is both technically practicable and economically reasonable.
Panhandle does not argue otherwise. Additionally, it was technically practicable and
economically reasonable for Panhandle to evaluate its compliance with the permit, and determine
that it could not comply with the annual NOx emission limit long before the Agency discovered
the exceedences.
 
Finally, Panhandle has reduced NOx emissions from engines 1116-1119 through its
environmental dispatch program. Under this program, Panhandle operates other engines before
running engines 1116-1119. Panhandle’s NOx emissions from engines 1116-1119 decreased in
1998 to 550.59 TPY. Accordingly, in addition to adding emission control technology to the
engines, Panhandle can reduce NOx emissions from the four engines through operational
changes. The Board finds that this type of operational control is also technically practicable and
economically reasonable. The Board weighs this Section 33(c) factor against Panhandle.

Subsequent Compliance.
Panhandle has not come into compliance with either the NOx
limit of its minor source permit or the PSD program. The Board weighs this Section 33(c) factor
against Panhandle.
 
Civil Penalty and Section 42(h) of the Act
 
Maximum and Requested Civil Penalties.
The maximum civil penalties the Board can
assess are established in Section 42(a) of the Act, which provides in part:
[A]ny person that violates any provision of this Act or any regulation adopted by
the Board, or any permit or term or condition thereof . . . shall be liable to a civil
penalty of not to exceed $50,000 for the violation and an additional civil penalty
of not to exceed $10,000 for each day during which the violation continues . . . .
415 ILCS 5/42(a) (2000).
Panhandle violated Sections 9.1(d)(1) and 9.1(d)(2) by constructing and operating a
major modification without complying with PSD requirements, including BACT. Panhandle
installed engines 1116-1119, and began operating them, in 1988. Panhandle has yet to comply
with PSD, though it applied for a PSD permit in August 1999, after the People filed this
complaint.
 
Panhandle also violated Section 9(b) of the Act by emitting NOx in excess of its
permitted 461.3 TPY limit. The calculations in the record show that Panhandle violated this
limit each year from 1989 to 1998. Panhandle operated the engines for only part of 1988, and
there is no evidence of an exceedence in that year. Panhandle admits that it has emitted NOx
from the four engines in amounts greater than the permit limit beginning in 1989 (the first full
year that the four engines operated) and continuing through 1998 (the last full year of operation
before the People filed this complaint). Ans. at 14.
 
Panhandles’s most recent permit expired on June 26, 1998. However, Section 39.5(4)(b)
of the Act provides:
 
An owner or operator of a CAAPP [Clean Air Act Permit Program] source shall
continue to operate in accordance with the terms and conditions of its applicable
State operating permit notwithstanding the expiration of the State operating
permit until the source’s CAAPP permit has been issued. 415 ILCS 5/39.5(4)(b)
(2000).
 
Panhandle submitted a CAAPP application to the Agency before the August 1996 inspection of
Glenarm Station. Under Section 39.5(4)(b) of the Act, Panhandle must still comply with its
operating permit, including the 461.3 TPY NOx emission limit. Accordingly, Panhandle
remained subject to, and violated, its operating permit, even though it expired.
 
Pursuant to Section 42(a) of the Act, the Board could impose a $50,000 civil penalty for
each violation and a $10,000 civil penalty for each day the violation continues. Section 42(a)
was amended July 1, 1990, having previously authorized maximum civil penalties of $10,000

 
28
per violation and $1,000 per day of continuing violation. Even if the Board applied the lower
maximum penalties under the old law for the violations through the first half of 1990, and the
current maximum penalties thereafter, the total possible civil penalty for these violations easily
exceeds $60 million.
 
The People ask the Board to impose a total civil penalty of $2,218,759 on Panhandle for
the violations. People Br. at 138. Of this proposed amount, the People base $1,590,000 on the
gravity of the violations, and $628,759 on the economic benefit that Panhandle received from
delaying compliance.
Id.
at 52, 82, 84, 104.
   
Panhandle states that it received no economic benefit from delayed compliance.
Panhandle argues that, if the Board imposes any civil penalty, the amount should be much lower
than that suggested by the People. Panhandle asserts that the facts of this case warrant a much
lower penalty amount attributable to the gravity of the violations, such as $10,000-$20,000 per
year. Panhandle maintains that any penalty period should be no more than eight years, 1989
through 1996. According to Panhandle, the Board should not assess a gravity-based penalty for
any noncompliance after 1996 because “Panhandle reduced emissions from the four engines
through its environmental dispatch program and took other measures to achieve compliance”
after learning of the exceedences. Pan. Br. at 89-90. Panhandle therefore suggests that if the
Board imposes any civil penalty, it should be no more than $80,000-$160,000 for all violations.
 
 
Section 42(h).
Section 42(h) of the Act (415 ILCS 5/42(h) (2000)) authorizes the Board
to consider the impact of any matter of record in determining an appropriate civil penalty.
Section 42(h) provides:
 
(h) In determining the appropriate civil penalty to be imposed under
subdivision[] (a) . . . of this Section, the Board is authorized to consider
any matters of record in mitigation or aggravation of penalty, including
but not limited to the following factors:
 
(1) the duration and gravity of the violation;
 
 
(2) the presence or absence of due diligence on the part of the violator
in attempting to comply with requirements of this Act and
regulations thereunder or to secure relief therefrom as provided by
this Act;
 
(3) any economic benefits accrued by the violator because of delay in
compliance with requirements;
 
(4) the amount of monetary penalty which will serve to deter further
violations by the violator and to otherwise aid in enhancing
voluntary compliance with this Act by the violator and other
persons similarly subject to the Act; and
 

 
29
(5) the number, proximity in time, and gravity of previously
adjudicated violations of this Act by the violator. 415 ILCS
5/42(h) (2000).
 
The Board considers each of these factors in turn.
 
Duration and Gravity of Violations.
Panhandle has been violating PSD requirements
since 1988, and continues to operate a major modification without a PSD permit. The PSD
program is a very important part of the federal Clean Air Act and Illinois’ effort to preserve its
air quality. Panhandle has also violated the 461.3 TPY NOx permit condition for at least ten
years, emitting an unauthorized 3341.67 tons of the pollutant NOx into the air from 1989 through
1998. The Board finds that these violations have been going on for a very long time and are very
serious. The Board weighs this Section 42(h) factor in aggravation of penalty.
 
 
Diligence in Attempting to Comply.
The Board finds that it was unreasonable for
Panhandle to rely
solely
on Agency inspections and permit renewals to determine its compliance
with the permitted NOx limit. Panhandle concedes that it simply “assumed that emissions from
the four new engines would be less than from the twelve old engines.” Pan. Br. at 2. The Act
requires more. Companies cannot do business in Illinois and simply assume that they are not
violating Illinois’ environmental laws.
 
As discussed, Panhandle could have readily verified its compliance status. The permit
requires Panhandle to keep records of the hours of operation and the fuel use of the four new
compressor engines. Panhandle kept those records. This information, along with the readily
available standard emission factor, was all that Panhandle required to calculate the four engines’
NOx emissions and compare them to the permit limit. For the annual emission reports,
Panhandle’s Houston staff calculated emissions of NOx from each of the engines at Glenarm
Station. Panhandle’s failure to determine its compliance status before the Agency informed it of
the exceedences demonstrates a blatant lack of diligence by Panhandle.
 
It is true that since receiving the 1997 violation notice, Panhandle has changed its
operations to reduce NOx emissions from engines 1116-1119. Through its environmental
dispatch program, Panhandle decreased the four engines’ NOx emissions from an all-time high
of 1173.69 tons in 1996 to 550.59 tons in 1998, though the latter amount is still approximately
90 tons above the permit limit. Panhandle also sought to have the Agency issue a new minor
source permit with a higher NOx emission limit for the four engines, and to add emission
controls to engines 1116 and 1117. In addition, in August 1999, after the People filed this
complaint, Panhandle applied for a PSD permit. This permit application proposes to install
“Clean Burn” technology for engines 1116 and 1117, and to upgrade the emission control
technology on engines 1118 and 1119.
 
These operational and administrative efforts since receiving the Agency’s notice weigh
somewhat in Panhandle’s favor. However, they did take place only in the face of looming
enforcement and have not resulted in compliance. Panhandle’s alarming lack of diligence during
the many years before then requires the Board to weigh this Section 42(h) factor in aggravation
of penalty.

 
30
 
 
Economic Benefit Accrued.
To assess any economic benefit that Panhandle accrued
from delayed compliance, both parties measured (1) the initial capital costs that Panhandle
would have incurred to install “Clean Burn” emission control technology on engines 1116 and
1117 and (2) the associated annual operating costs that Panhandle would have incurred. Further,
both parties used the weighted average cost of capital (WACC) to calculate this economic
benefit. The WACC combines the cost of debt and capital and weighs these costs based on a
proportion of a company’s debt and equity to determine that company’s cost of capital,
i.e.
, its
cost of obtaining money. The WACC incorporates the time value of money. Tr. at 166, 178-80,
195, 229-30, 352-55, 357, 919, 926. The WACC has been accepted in federal court to determine
economic benefit from violating environmental requirements.
See
United States v. Smithfield
Foods, Inc., 191 F.3d 516, 529-31 (4th Cir. 1999). To calculate Panhandle’s WACC, both
parties used data on Panhandle’s former parent company, Panhandle Eastern Corporation, which
changed its name to PanEnergy Corp. in the mid-90’s. Panhandle, as a wholly-owned
subsidiary, was financially managed by its parent corporation. Tr. at 180, 295, 358-60; H.O.
Exh. 1-10
 
The People state that “[b]ecause of the high costs often associated with environmental
control expenditures under the PSD program, the incentives for delayed or avoided costs that
might be derived by one competitor over the other are more prevalent or likely to occur.” People
Br. at 83. The People’s financial expert, Dr. John Nosari,
12
calculated a WACC for Panhandle.
Tr. at 358, 362-88, 390-91; People Exh. 7, 25-27; H.O. Exh. 1, 4, 5, 7, 8. Using Dr. Nosari’s
WACC calculations, Mr. Gary Styzens of the Agency
13
assessed Panhandle’s economic benefit.
The People assert that Panhandle’s economic benefit from delayed compliance is $628,759. The
People derived this figure from an initial capital investment of $285,328 for the emission
controls and a total cost of $355,431 to operate and maintain the controls, reduced by $12,000 to
reflect partial years of noncompliance (1988 and 1999) for the calculation. These figures were
adjusted for inflation and exclude tax benefits. Tr. at 195, 198-216, 229-32, 235, 238, 240-41,
245-50, 293-95, 320, 368-69, 394-95, 1309-33; People Exh. 8-10, 18-20; People Br. at 106-13.
 
12
Dr. Nosari received his Ph.D. in Business Administration from St. Louis University, majoring
in accounting and minoring in finance. He is a licensed Certified Public Accountant and holds
the professional designation of a Certified Internal Auditor. He has taught for over 20 years in
courses that include accounting, finance, and auditing. Dr. Nosari is currently an Associate
Professor of Accountancy at the University of Illinois at Springfield. Tr. at 343-51; People Exh.
24.
 
13
Mr. Styzens is a Certified Internal Auditor with the Agency. He has approximately 15 years
of field experience in auditing, and received a Masters in Business Administration in 1983 from
Southern Illinois University. Mr. Styzens joined the Agency in 1991 as an audit supervisor,
which is his current position. For the last five years, Mr. Styzens has performed audits relating
to economic benefit from noncompliance. Tr. at 155-72; People Exh. 6.
 

 
31
Panhandle’s financial expert, Mr. Jasbinder Singh,
14
calculated a different WACC for
Panhandle. He assessed Panhandle’s economic benefit from delayed compliance to be $454,904
($150,785 for capital costs plus $304,119 for operating costs).
15
These calculations of Panhandle
and the People differ largely because components of the WACC were calculated differently,
such as the growth rate of the parent corporation’s stock. Panhandle used a growth rate of
2.07%, but the People used a growth rate of 8%. Mr. Singh used average stock prices over
various time periods to calculate the growth rate, while Dr. Nosari used certain daily or spot
stock prices. Both sides assert that the manner in which the other’s expert calculated a growth
rate is subject to manipulation. Tr. at 362-64, 375-80, 448-56, 463, 913, 923, 925-26, 932, 962-
66, 1037, 1429-31, 1433-35, 1437; People Exh. 7, 26; Pan. Exh. 23; H.O. Exh. 1; People Br. at
92-94; Pan. Br. at 63-64, 76-77.
 
Using the calculation of either party, the economic benefit that Panhandle accrued was
approximately half a million dollars. The Board finds that half a million dollars represents a
good approximation of Panhandle’s economic benefit from delayed compliance. That the
respective experts used different underlying assumptions and still ended up with calculations of
economic benefit in the same dollar range only fortifies the Board’s finding.
  
Panhandle maintains, however, that it has received no economic benefit from delayed
compliance. Panhandle offers two arguments for this position, each of which is based on the
opinions of Mr. Singh. First, Panhandle argues that even if it had incurred the expense of
installing the emission controls in 1988, the Federal Energy Regulatory Commission (FERC)
would have allowed Panhandle to set its rates to recover that expense plus a reasonable return.
Panhandle asserts that the FERC’s rate structure would have provided a reasonable rate of return
to Panhandle, regardless of whether Panhandle incurred the capital and operating costs of the
emission controls. Pan. Br. at 54-57. Therefore, according to Panhandle, “no economic benefit
component of a penalty would be necessary to put Panhandle in the same position it would have
been in had it installed Clean Burn on engines 1116-1117 in 1988.”
Id.
at 55.
 
The Board rejects this argument. Regardless of whether a company, FERC-regulated or
otherwise, can pass its compliance costs along to its customers, avoiding those compliance costs
(
i.e.
, having that money for other uses) is an economic benefit. Panhandle has enjoyed that
benefit for years. Moreover, with the FERC’s restructuring of the natural gas pipeline industry
14
Mr. Singh has a Bachelor of Technology degree in Civil Engineering from the Indian Institute
of Technology and a Masters of Science degree in Civil Engineering from Carnegie-Mellon
University. From 1970-1973, he was in the Ph.D program in regulatory economics at Carnegie-
Mellon University. Mr. Singh has provided economic analysis of federal regulations for
approximately 23 years and has provided litigation support related to economic benefit from
noncompliance for the last 10 years. He has also written five published papers on economic
benefit issues. Mr. Singh has a consulting business, Policy Planning & Evaluation, Inc. Tr. at
885-86, 901-03; Pan. Exh. 22.
 
15
Despite this calculation, Mr. Singh’s opinions about the Federal Energy Regulatory
Commission and “retrofitting” costs are the basis for Panhandle’s position that it has had no
economic benefit from delayed compliance.

 
32
in the 80’s and 90’s, Panhandle faced increased levels of competition. Tr. at 827-38, 849, 854-
57, 875-76, 1329, 1342-44, 1387-88. For example, to maintain existing customers and attract
new ones, Panhandle charged at rates below what it was allowed to charge. Tr. at 828, 849, 855-
56, 875-76. In doing so, Panhandle was not encumbered by these emission control compliance
costs, as a compliant competitor so situated would have been. For its own economic benefit,
Panhandle had ample incentive to keep its costs down. Tr. at 1329, 1342-44.
 
Second, Panhandle argues that it has received no economic benefit from delayed
compliance because any calculated economic benefit to Panhandle is exceeded by the cost of
“retrofitting” the engines with emission controls now. Panhandle asserts that it is more
expensive to add the emission controls to these operating engines now than it would have been to
install the controls in 1988 during the construction project. Panhandle dismantled and
modernized the engines before installing them in 1988. Panhandle argues that the costs of
adding “Clean Burn” technology today include not only the costs for updated technology but
also the costs to take the engines apart again. Mr. Singh estimated that it would cost $943,948 to
install “Clean Burn” control technology on engines 1116 and 1117 today. Tr. at 727, 947, 956,
962-65; Pan. Exh. 23, Tab. 3; Pan. Br. at 62-63.
 
The Board notes that the Fourth District Appellate Court has affirmed the Board’s
decision to impose a civil penalty based in part on a violator’s economic benefit of delayed
compliance.
See
ESG Watts v. PCB, 282 Ill. App. 3d 43, 52-53, 668 N.E.2d 1015, 1021-22 (4th
Dist. 1996). In ESG Watts, the Board found that the economic benefit of paying landfill fees late
was the interest rate on money the violator could have borrowed to timely pay the fees.
See
ESG
Watts, 282 Ill. App. 3d at 49-50, 668 N.E.2d at 1020. The court upheld the Board’s finding on
economic benefit even though the violator had eventually paid its landfill fees.
See
ESG Watts,
282 Ill. App. 3d at 47, 51, 668 N.E.2d at 1018, 1021. That a violator will still incur costs to
come into compliance does not eliminate the economic benefit of delayed compliance,
i.e.
, funds
that should be spent on compliance were available for other pursuits.
 
Panhandle’s retrofit argument also conflicts with the purpose of Section 42(h)(4)—
deterring violations. Any extra compliance costs from retrofitting are self-imposed and exist
solely because the violator did not pay to comply on time. Applying the retrofit argument could
encourage companies to put off compliance or at least not be as diligent as they should be in
monitoring compliance—any penalty that a company might face if it gets caught in violation
could be diminished because the company did
not
spend money to comply when it should have.
The deterrent effect of civil penalties is compromised if the violator gets “credit” for ignoring its
legal obligations. Panhandle’s argument turns one of the primary purposes served by civil
penalties on its head and the Board rejects it.
   
Penalty Amount That Will Deter Further Violations and Aid in Enhancing Voluntary
Compliance.
The PSD violations have been going on for more than ten years, and the permit
exceedences for at least ten years. The violations have undermined the ability of the PSD
program to prevent degradation of air quality and resulted in thousands of unpermitted tons of
the pollutant NOx being emitted into the air. Until it received notice of the exceedences from the
Agency, Panhandle for years exhibited a troubling lack of diligence in determining its
compliance status. This lack of diligence stands out given the ease with which Panhandle could

 
 
33
have determined its compliance status. This record does not demonstrate that Panhandle
knowingly committed these violations before 1996 when it learned of the excess emissions
problem from the Agency. However, even Panhandle suggests that up to $160,000 would be an
appropriate penalty amount based solely on the gravity of the violations.
 
Under this Section 42(h) factor, to arrive at a penalty amount that will have a deterrent
effect, the size of the violator is an appropriate consideration.
See
Charter Hall Homeowner’s
Assoc. v. Overland Transportation System, Inc., PCB 99-81, slip op. at 14 (May 6, 1999).
Panhandle is a large corporation. It has operations in many states, including five compressor
stations in Illinois. Panhandle spent approximately $15 to $20 million at Glenarm Station for the
1988 construction project alone. Panhandle has also had considerable parent corporations
behind it.
See
United States v. Municipal Authority of Union Twp., 150 F.3d 259, 267-69 (3d
Cir. 1998) (considering parent corporation’s financial information when assessing penalty
against subsidiary). For example, PanEnergy Corp.’s net income was $171.6 million in 1993
and $344.4 million in 1996. H.O. Exh. 9 at 37; H.O. Exh. 10 at 37. After PanEnergy Corp.,
Panhandle was owned by Duke Energy Corporation, a Fortune 500 company. Panhandle’s
current parent corporation, CMS Energy Corporation, is also a Fortune 500 company. Panhandle
has also enjoyed an economic benefit of upwards of a half million dollars from delayed
compliance.
 
Under these circumstances, the Board finds that a civil penalty of $850,000 is required to
deter further violations by Panhandle and enhance voluntary compliance by Panhandle and other
similarly situated entities. This dollar amount will help to ensure that Panhandle and companies
like it actually review the permits they accept, and take the steps necessary to monitor their
compliance, such as having basic communications between those employees familiar with
engine emissions and those familiar with permit limits.
 
 
Previously Adjudicated Violations.
The record contains no evidence that Panhandle has
previously been adjudicated to have violated the Act. The Board weighs this Section 42(h)
factor in mitigation of penalty.
 
Board Findings on Appropriate Remedy
 
The Board orders Panhandle to cease and desist from further violations of Sections
9.1(d)(1), 9.1(d)(2), and 9(b) of the Act. For these violations of PSD and permitting
requirements, Section 42(a) of the Act authorizes the Board to impose a civil penalty in the tens
of millions of dollars. The People seek approximately $2.2 million in civil penalties. Panhandle
argues that no civil penalty is warranted, but if the Board awards any civil penalty, it should not
exceed $160,000.
 
Panhandle argues that any penalty assessed against it should be mitigated because the
Agency should have discovered the violations sooner, and the Agency’s failure to find the
violations sooner allowed Panhandle to continue violating the Act. As discussed above,
however, the violations could have been avoided
entirely
if Panhandle had simply reviewed its
permit in 1988 to see if the annual NOx limit would accommodate Panhandle’s planned
operations. Instead, Panhandle accepted the 1988 permit and then effectively ignored its

 
 
34
emission limit. Panhandle did not even become aware of its excess NOx emissions until eight
years after accepting the minor source permit, and then only because the Agency found the
problem.
 
Panhandle unlawfully emitted 3341.67 tons of NOx into the air over ten years. NOx is a
pollutant. When unlawfully emitted into the air, it can result in health problems. Panhandle’s
violations also interfere with the Agency’s ability to see that the PSD program prevents our air
quality from deteriorating. PSD is a cornerstone of the federal Clean Air Act. The General
Assembly found that PSD “regulate[s] the issuance of preconstruction permits to insure that
economic growth will occur in a manner consistent with the preservation of existing clean air
resources . . . .” 415 ILCS 5/9.1(a) (2000). Companies cannot be allowed to accept minor
source permits for the purpose of avoiding the expenses of PSD compliance, and then have little,
if any, regard for meeting their permitted emission limits.
 
While Glenarm Station has social and economic value and is suitably located, Panhandle
has had technically practicable and economically reasonable means to comply and is still out of
compliance. Panhandle’s delays have also given it considerable economic benefit over the years.
Though Panhandle has made efforts to comply, these came only with enforcement clouds
gathering. Panhandle is a large corporation with multi-state operations. Panhandle could have
readily prevented these lengthy and serious violations by exercising minimal due diligence, but it
failed to do so. Companies doing business in Illinois must at least take the basic steps necessary
to determine whether they are complying with the permits they hold. Neither Panhandle nor any
other company can foist that responsibility on the Agency. Panhandle ultimately has only itself
to blame for these major violations.
 
After considering the factors of Sections 33(c) and 42(h) of the Act, the Board orders
Panhandle to pay a civil penalty of $850,000. Consistent with Section 42(a) of the Act, the
Board orders Panhandle to pay this civil penalty to the Environmental Protection Trust Fund.
See
415 ILCS 5/42(a) (2000).
 
  
Costs and Attorney Fees
 
The People request $128,902.25 in costs and attorney fees pursuant to Section 42(f) of
the Act (415 ILCS 5/42(f)(2000)), which provides in part:
 
Without limiting any other authority which may exist for the awarding of
attorney’s fees and costs, the Board or a court of competent jurisdiction may
award costs and reasonable attorney’s fees, including the reasonable costs of
expert witnesses and consultants, to the State’s Attorney or the Attorney General
in a case where he has prevailed against a person who has committed a willful,
knowing or repeated violation of the Act. 415 ILCS 5/42(f)(2000).
 
It is undisputed that Panhandle, even after learning of its excess emissions problem from
the Agency, has continued to operate the four engines without a PSD permit or BACT and to
emit NOx above the 461.3 TPY limit. Panhandle has therefore knowingly violated the Act since
it became aware in 1996 that it was exceeding its permit limit.
See
People v. Kershaw, PCB 92-

 
 
35
164, slip. op. at 8 (Apr. 8, 1993) (violations were “knowing” when they continued after
respondent was notified of violations). In addition, Panhandle first violated its annual NOx limit
in 1989. By exceeding that annual permit limit each year thereafter, Panhandle repeatedly
violated Section 9(b) of the Act. Accordingly, under Section 42(f), Panhandle repeatedly and,
since 1996, knowingly violated the Act. The Board therefore may award reasonable costs and
attorney fees to the People.
 
Of the People’s requested $128,902.25 in fees and costs, $113,298 represents attorney
fees and $15,604.25 represents costs. The attorney fees consist of 944.15 hours at $120 per
hour. The costs reflect deposition transcript charges for 11 witnesses ($2,329.25) and the fees of
an expert witnesses, Dr. Nosari ($13,275). Dr. Nosari’s fees represent 189 hours of consulting at
$50 per hour and 45 hours of litigation support at $85 per hour. These costs and fees are
supported by affidavits. People Br. at 136-37, Att.1; People Reply Br. at 65, Add.
  
The Board notes that of the 944.15 attorney hours, 109.6 hours were spent on three of the
People’s motions: (1) the People’s December 26, 2000 motion to reverse the hearing officer’s
ruling to exclude from evidence People’s Exhibit 5, a letter from USEPA to the Agency; (2) the
People’s February 28, 2001 motion to strike portions of Panhandle’s response brief; and (3) the
People’s March 12, 2001 motion for the Board to reconsider its February 1, 2001 order affirming
the hearing officer’s ruling to exclude the People’s Exhibit 5. People Br., Att. 1; People Reply
Br., Add. Panhandle opposed and the Board denied each of these motions.
See
Panhandle, PCB
99-199, slip op. at 5 (Oct. 18, 2001).
  
Panhandle “committed . . . knowing [and] repeated violation[s] of the Act.” 415 ILCS
5/42(f) (2000). Panhandle’s efforts to comply have not resulted in compliance and have come
only when confronted with the prospect of enforcement. Given the rates charged and the
complexity of prosecuting this case, the Board finds that the People’s costs and attorney fees are
reasonable.
See
,
e.g.
, People v. Spirco Environmental, Inc., PCB 97-203, slip op. at 2 (finding
rate of $120 per attorney hour to be reasonable). However, the Board will not order Panhandle
to pay attorney fees for the People’s three unsuccessful motions described above. In so doing,
the Board is not finding that the People’s motions were frivolous. Rather, the Board is
exercising its discretion, under Section 42(f) of the Act, by not requiring Panhandle to pay
$13,152 in attorney fees that are attributable solely to motions on which the People did not
prevail. The Board therefore orders Panhandle to pay $115,750.25 of the People’s costs and
attorney fees. Under Section 42(f), Panhandle must pay these costs and fees to the Hazardous
Waste Fund.
See
415 ILCS 5/42(f) (2000).
 
  
CONCLUSION
 
The Board finds that Panhandle violated the requirements of the Act for at least ten years.
These requirements include PSD restrictions on pollutant emissions under the federal Clean Air
Act, which are designed to ensure that our air quality does not deteriorate. When Panhandle
undertook a construction project in 1988, it accepted a NOx emission limit in a minor source
permit to avoid the expenses of PSD. With the minor source permit, Panhandle proceeded to do
business in Illinois while repeatedly emitting far more NOx than its permit allowed. Panhandle’s
NOx emissions from the four new engines were dramatically higher than its emissions from the

 
 
36
12 retired engines in the year before the construction project. In short, Panhandle accepted a
permit that it could not live with, which allowed it to avoid PSD compliance costs.
 
Before 1996 when the Agency discovered Panhandle’s excess emissions, Panhandle
made no effort to determine its compliance status. Doing so would have been easy for
Panhandle. Unfortunately, at Panhandle, the left hand did not know what the right hand was
doing, and
vice versa
. Panhandle staff who knew how much NOx was being emitted did not
know about the permit limit, while staff who knew about the permit limit did not know how
much NOx was being emitted. Responsibility for a company’s compliance with its air permit
must rest with that company.
 
The Board orders Panhandle to cease and desist from further violations and to pay a civil
penalty of $850,000. The Board also awards the People $115,750.25 in costs and attorney fees
because Panhandle repeatedly and, since 1996, knowingly violated the Act.
 
This opinion constitutes the Board’s findings of fact and conclusions of law.
