ADDITIONAL COMMENTS
NOW COMES the Illinois Environmental Protection Agency (“Agency” or “Illinois
EPA”), by one of its attorneys, Scott O. Phillips, Deputy Counsel, and hereby files additional
comments as follows:
1.
In the Hearing Officer’s order dated September 25, 2000, the Hearing Officer asked
the Illinois EPA a series of questions. The Illinois EPA responded to those questions
in its AGENCY RESPONSE TO QUESTIONS FROM HEARING OFFICER
ORDER DATED SEPTEMBER 25, 2000, filed on October 4, 2000. Also, the Illinois
EPA responded to these questions at the Pollution Control Board’s (“Board’s”) public
hearing on October 6, 2000. In its written response and at hearing, the Illinois EPA
deferred responding to Questions 18, 19, and 20 contained in the Hearing Officer’s
order so that the Illinois EPA could provide the Board with the most current
information possible on the permit-related statistics requested by the Board.
Comment: Attached Exhibit 1 is a summary listing of natural gas-fired turbine
electrical power plant projects since 1998, updated as of November 2, 2000. This
summary is in chronological order based upon the date that an application for the
plant was first received (or the date of expiration or withdrawal).

This filing submitted on recycled paper.
2
Also attached is Exhibit 2 which contains a printout of a spreadsheet listing in more
detail these permit-related statistics requested by the Board. Attached Exhibit 3 is an
electronic copy of this spreadsheet in Microsoft Excel format. Attached Exhibit 4
contains an explanation of certain columns within this spreadsheet. Note that in
spreadsheet cells where no information is provided, such as emissions limitation
information, this typically means that the information is not yet available because the
construction permit application is still pending.
2.
At the Board’s public hearing held on October 6, 2000, Board Member Kezelis
inquired as to the use of actual, pound-per-hour emissions data used modeling.
Comment: For modeling purposes, the Illinois EPA requires that applicants for new
peakers use the maximum permitted hourly emission rate to address the NAAQS for
each criteria pollutant having an NAAQS expressed as a “short-term” average. For
PM-10 (24-hour NAAQS), SO
2
(24-hour and 3-hour NAAQS), and CO (1-hour and
8-hour NAAQS) the maximum hourly emission rate is assumed for an operating rate
of 24 hours per day. The Illinois EPA also requires applicants to perform evaluations
of impacts during reduced-load operation and startup in order to assure that the
emissions for these configurations will not threaten air quality. For NO
2
(annual
NAAQS), the emissions (or operating rates) permitted on an annual basis are assumed
in the modeling.

“Actual” emissions are not used since the source is modeled prior to construction and
therefore actual emission data is not available. However, after the source is built, in
order for the source to remain in compliance with its permit conditions, the actual
emissions cannot exceed the permitted emissions that were used for modeling the
source.
3.
At the Board’s public hearing held on October 6, 2000, the Board inquired as to how
localized impacts are assessed, and what methodologies are employed to make the
modeling conservative.
Comment: There are several aspects of the modeling process that ensure the
conservatism of the results. First, as mentioned previously, the modeling incorporates
emission rates that reflect maximum operating rates at maximum permitted hourly
emissions on a continuous basis (i.e., 24 hours per days). This assumption is applied
not only for the proposed source but for all background sources included in the
modeling as well. Second, the maximum modeled impacts are added to a
conservatively estimated background concentration determined from nearby
monitoring stations (typically the highest monitored values for the worst of three
years of data are used to estimate background concentrations). Third, concentrations
are calculated by the model using five years of hourly meteorological observations to
determine worst-case conditions. In other words, the worst-case meteorological

This filing submitted on recycled paper.
4
conditions are assumed to occur at the same time as the highest background
concentrations are observed and at the same time that the new source and all other
sources are operating at maximum load conditions. Finally, concentrations are
evaluated at all locations off plant property, including but not limited to the locations
of nearby schools and residences. Typically the highest concentrations reported in
modeling studies are predicted to occur at or immediately downwind of plant fence
lines, in areas with little or no population exposure.
4.
At the Board’s public hearing held on October 6, 2000, the Board requested an
explanation of the term “small, if not insignificant” used by the Illinois EPA in
describing air quality impacts.
Comment: The Illinois EPA typically uses U.S. EPA’s definition of “significant air
quality impact” (from PSD guidance) in describing air quality impacts. The
established significant impact thresholds are expressed as micrograms per cubic meter
(ug/m
3
) and are usually in the range of 1% to 5% of an applicable NAAQS (
see
Illinois EPA Group Exhibit 2, Exhibit 10, Table 2). For example, the significant
impact threshold for NOx is 1 ug/m
3
while the NAAQS is 100 ug/m
3
for an annual
average. The significance thresholds are used as a trigger in the PSD air quality
analysis process to require more detailed analyses and are not intended as “not to be
exceeded” limitations. As presented by the Illinois EPA, the modeling analyses have

5
shown that most peakers will not cause significant air quality impacts (i.e., their
maximum impacts will not exceed the PSD significant impact thresholds). In a few
cases, impacts have been shown to be “significant” but were still only a small
percentage of the applicable NAAQS, thus the reference to “small” impacts in the
Illinois EPA’s testimony.
5.
At the Board’s public hearing held on October 6, 2000, the Board requested data from
the continuous emissions monitoring system (CEMS) at the Elwood facility located in
Will County.
Comment: Exhibit 5 contains the CEMS data from the Elwood facility. Note that:
a. The data provided in Exhibit 5 is from the second quarter of 2000. Validated
third quarter data is not yet available.
b. Each bundle of information contains the same types of data, one bundle for
the CEMS for each of the four units located at Elwood (each unit has a
separate CEMS). The CEMS at Elwood measure only NOx emissions. The
monitors are operated in accordance with the Acid Rain regulations.
c. The data included on the bar charts each type of data recorded by the CEMS
for each day the unit operated. As the units did not operate every day during
the quarter, only those days on which they did operate show recorded data.
These charts provide the megawattage (“Gross Load”), the NOx rate in

6
pounds/mmBtu, the total pounds of NOx emitted (“NOx Mass”), and the
unadjusted NOx concentrations in parts per million.
d. A table is also provided that includes numerical data for each unit’s daily
operation. This table provides the total number of hours per day that the unit
operated, the total heat input per day, the average NOx rate per day, the total
number of tons of NOx emitted per day, and the number of tons of carbon
dioxide emitted (a calculated number based upon oxygen content of the
exhaust),
1
and the total gross load in megawatts.
e. The second group of tables provides hourly data for the operating hours, the
total heat input for that hour, the NOx rate for that hour, the number of pounds
of NOx emitted during that hour, the tons of CO
2
emitted during that hour (a
calculation) and the gross load during that hour. The first day of operating in
April for Unit 4 was on the 4
th
. The facility operated for half an hour or less
during the hour between 7:00 and 8:00 a.m. The heat input during this time
was a little over 544 mmBtu. Its NOx rate during that half hour was 0.112
ppm. It emitted about 60 pounds of NOx. It produced 40 megawatts of
electricity. The F Factor shown is a constant value specific to natural gas (the
fuel used at Elwood) that is used in the calculation of emission rates. During
the rest of the time on April 4 until the hour between 10:00 and 11:00 p.m.,

This filing submitted on recycled paper.
7
the heat input steadied at around 1,750 lb/mmBtu/hr until shutdown.
Likewise, the NOx rate, the number of pounds of NOx emitted, and the gross
load all steadied until shutdown. Note that start-up and shutdown each took
less than an hour. For purposes of comparison, the NOx emission limits
applying to the turbines during normal operation are 0.061 pound/mmBtu and
108 pounds per hour, and the units are rated at 170 MW output a maximum
firing rate of 1763 mmBtu/hr (Low Heating Value) at 49° F.
f. The final piece of information here is a print-out of U.S. EPA’s “Emissions
Tracking System,” cumulative data through the second quarter of 2000. As
you can see, the Elwood Energy facility is the 8
th
facility listed on this page.
This data identifies the total operating hours for the year to the end of the 2
nd
quarter per unit, the cumulative annual heat input, the cumulative annual
emissions (the values provided are the default values for natural gas), the
average annual NOx emission rate in lb/mmBtu, the cumulative mass
emissions of CO
2
, and the percentage of time that the monitors were operating
(the Elwood monitors operated well within the expectations for CEMS under
40 CFR Part 75).
1
Emissions of carbon dioxide (CO
2
) are also identified on this exhibit. Electrical power plants in general are major
contributors to greenhouse gas emissions of CO
2
, and data on emissions of CO
2
is collected by the U.S. EPA’s Acid
Rain Program as related to global warming.

During this proceeding, witnesses expressed concerns regarding the amount of
emissions that may occur from natural gas-fired peaking power plants during start-up.
Comment: General information and background on emissions from a turbine during
startup is contained in U.S. EPA’s Alternative Control Technology document (
see
Illinois EPA Group Exhibit 2, Exhibit 4). In Section 5.2 of this document, U.S. EPA
provides a description of how low-NOx combustors, with which new peaking
turbines are equipped, operate and how emissions of pollutants vary during startup.
This information generally describes the two different phenomena that are occurring
during the startup of the turbine. One phenomenon occurs for pollutants that are
incomplete combustion products, i.e., CO and VOM, while another is taking place for
NOx, which is a byproduct of high-temperature combustion. Upon startup of the
combustors, the concentration of NOx begins at an intermediate level associated with
“natural” combustion. The NOx concentration gradually increases as the rate of
firing is increased and combustion conditions improve to a level at which the
combustion process is sufficiently stable to begin low-NOx operation. At this point,
the concentration of NOx drops rapidly, as pre-mixing of fuel and air is initiated or
water begins to be injected into the combustors. The concentration of NOx then
remains relatively stable as the operation of the turbine increases to full load. In
contrast, during startup, the concentrations of incomplete combustion products start at
very high levels, but then rapidly decrease as the conditions for combustion

9
(temperature and turbulence) stabilize as fuel firing rate is increased. The
concentrations gradually decrease further to normal levels as the combustion
conditions in the combustors continue to improve, with only a brief interruption, as
the concentrations temporarily jump when the combustors are shifted into low-NOx
operation.
In applying this theory to a particular turbine to develop a quantitative determination
of emissions during startup, one must consider a number of elements. These include
the variation of fuel firing rate and airflow during the startup, the overall duration of
the startup, the degree to which NOx is reduced by low-NOx operation of the
combustor, and the consequences of this degree of NOx reduction on combustion
conditions and emissions of incomplete combustion products. For purposes of
comparing turbines, it is also necessary to consider the safety factors included in
projections of emissions provided by equipment manufacturers.
The information provided in permit applications to date suggests that startup does not
have a significant effect on the overall NOx emissions of a turbine, when emissions
are evaluated in terms of pounds per hour. Although the concentrations of NOx are
somewhat higher during startup, this is balanced out by the reduced level of operation
during startup. Thus, NOx emissions during an hour with a startup are similar, or
only slightly higher than those during an hour of normal operation. This is confirmed
by NOx emission data collected by the NOx CEMS at the Elwood Energy facility. In

This filing submitted on recycled paper.
10
particular, the CEMS data show a NOx emission rate in lb/mmBTU during a startup
that is about twice the normal rate.
2
The CEMS data shows that the peaking turbines
presently at Elwood Energy normally operate at about 0.05 to 0.055 lb NOx/mmBtu.
(The permit limit is 0.061 lb/mmBtu, based on an exhaust concentration of 15 ppm
NOx.) During startup, NOx emissions are in the range of 0.1 to 0.115 lb/mmBtu. Of
course, the average firing rate during a startup is about half of the turbines capacity.
This indicates that startup of these peaking turbines does not significantly change the
hourly NOx emissions of these turbines.
A different conclusion is reached for the new model of turbines and combustors that
are being added to Elwood. During normal operation, these new units are required to
comply with a lower emission rate than the existing units, i.e., 0.037 lb NOx/mmBtu.
(This limit is equivalent to 9 ppm NOx.) Assuming that the emissions of NOx from
these turbines during startup itself are unchanged from the startup emissions for the
older turbines, the emissions during an hour when one of these new turbines startup
could be about 25 percent higher than the emissions during a normal hour of
operation. If the turbines typically operate five hours at a stretch, however, the
consideration of startup would still only increase overall NOx emissions from the
turbine by about five percent. Nevertheless, as combustors become more effective in

that start-up for its natural gas-fired peaker turbines takes about 20 minutes.

lowering NOx emissions during normal operations, the startup emissions will likely
become higher in comparison.
7.
During this proceeding, a witness suggested that the NOx waiver applies to the
Metro-East nonattainment area as well as the Chicago nonattainment area.
Comment: U.S. EPA never granted Illinois’ request for a NOx waiver for Metro-East
ozone nonattainment area, and nonattainment New Source Review for VOM and
NOx applies to the new electric generating units (EGUs) locating in that area. The
major source threshold for purposes of New Source Review is 100 tons per year in
the Metro-East nonattainment area, as opposed to 25 tons per year in the Chicago
ozone nonattainment area, because Metro-East is a moderate ozone nonattainment
area.
8.
During this proceeding, a witness referred to the findings and recommendations of the
Ozone Transport Assessment Group (“OTAG”), referring to regions and subregions
as used in the context of OTAG. This witness suggested that the regions and
subregions of OTAG might be comprised of Illinois or even the Lake Michigan
nonattainment area.
Comment: The OTAG region was comprised of 37 jurisdictions from North Dakota
to Texas and east to the Atlantic Coast. At one point, OTAG modeled the effect on

12
regional ozone levels of control strategies applied in subregions. Each of these
subregions was made up of a number of states. The regions and subregions did not
refer to single nonattainment areas or portions of nonattainment areas or even
individual states. It is important to keep in mind that OTAG’s major finding was that
NOx is a regional problem and that regional reductions of NOx, meaning reductions
in the NOx SIP call area, are necessary to generally reduce transported ozone and
ozone precursors. The findings of OTAG addressed the benefits of reducing NOx as
a regional, transport problem rather than as a local problem within nonattainment
areas such as the Chicago ozone nonattainment area.
9.
During this proceeding, a witness suggested that the OTAG process refuted the
validity of NOx disbenefit.
Comment: OTAG recognized NOx disbenefit as a local issue. OTAG also
recognized that local control measures, meaning those control strategies unique to a
given state or nonattainment area, might be necessary in addition to the regional NOx
reductions it recommended to U.S. EPA. These local measures would likely be
strategies to reduce emissions of VOCs, but they might be measures to reduce NOx
emissions in addition to or other than those identified to U.S. EPA; however, OTAG
made no findings or recommendations with regard to the benefits of local NOx
reductions.

This filing submitted on recycled paper.
13
10.
Several witnesses suggested that the NOx SIP call supported the need for NOx
reductions within the Chicago ozone nonattainment area as part of the State’s
attainment demonstration.
Comment: The purpose of the NOx SIP call is to address ozone transport. Consistent
with OTAG’s findings, U.S. EPA issued the NOx SIP call to require reductions in
regional NOx in order to reduce the transport of ozone and ozone precursors. These
regional reductions of NOx are intended to enable Illinois and the other Lake
Michigan states to demonstrate attainment with the 1-hour ozone standard in the Lake
Michigan area, in conjunction with any local control measures that might be
necessary or appropriate. Without regional reductions of NOx, Illinois would have to
implement extreme levels of reductions of VOCs in the nonattainment areas. If the
regional reductions in NOx do not actually provide attainment as our modeling
predicts or if there is significant importation of NOx allowances under the national
trading program such that NOx emissions in the State continue to interfere with
attainment, then the Illinois EPA will have to impose additional emissions limitations
as appropriate. In any event, it is important to keep in mind that the NOx SIP call
addresses NOx as a regional issue involving a large sector of the eastern portion of
the United States.

EXHIBIT 3
This exhibit is a computer disk containing
the Microsoft Excel spreadsheet printed in
Exhibit 2.

EXHIBIT 4

Explanation of Certain Columns in Exhibit 1
Spreadsheet
Column 7:
Identifies whether the site is an existing site,
i.e.
, the site already
has electric generating units (EGUs) located there, or a new site,
i.e.
, the site has never been used for EGUs previously.
Column 10: Identifies the type of permit: construction (C), operating (O), or
Title V.
Column 13: Identifies the date that the operating permit for the facility expires.
In most cases, the new EGUs are still operating under their
construction permits, which they may do for a period of time.
Column 15: Identifies the type of turbine: simple cycle turbine (“SCT”) or
combined cycle turbine (“CCT”). Note that the rows addressing
combined cycle turbine facilities are highlighted to make them
easily distinguishable from the simple cycle facilities. The Agency
left the two types of turbine facilities intermixed on this table so
that the Board could see more easily where simple cycle turbines
and combined cycle turbines are intermingled at a single site.
Column 16: Identifies the number of identical turbines located at the site. In
some instances, a site will have a number of turbines that are not
identical or where the conditions or other specifics for the turbines
are different, in which case the Agency has provided more than
one row for that facility. And example is Rows 23 through 25,
where there are a total of four turbines, but they are three different
types of turbines, as indicated in Columns 17 and 18.
Column 21: Identifies the type of NOx control employed at the turbine: dry
low NOx burners (“DLN”), water injection (“WI”), or selective
catalytic reduction (“SCR”). Heat recovery steam generators
(“HRSG”) are found only on combined cycle units and are
sometimes referred to as the waste heat boilers.
Column 25: Identifies the types of fuel for which the unit(s) is/are permitted.
Where a second fuel is indicated, it is the back-up fuel. “JP-4”
refers to jet fuel.
Column 26: Identifies whether the unit is a peaking unit or will operate as more
than a peaking unit. Operating “more than a peaking unit” means
that the unit may be a baseload unit, expected to run almost
continuously, or a cyclic unit that will run for longer periods of

time than a peaker but not to full baseload timeframes. These last
two types are generally the combined cycle units, and the table
identifies them as “base.” In actuality, the Agency is not provided
the information as to whether the owner/operator considers the unit
a baseload unit or some other cyclic unit, other than any
information provided that limits hours of operation. The Agency
has just called them all “base” for simplicity’s sake.
Column 39: Identifies the type of monitoring required if Part 75 monitoring is
not required. In some cases, the construction permit is not
sufficiently developed to determine the appropriate type of
monitoring to be required.
