ILLINQJSENVIRONMENTAL PROTECTION AGENCY'S llR8-FILED ANSWERS TO
PRE-FILED OUESTIONSQF PRAIRIE RIVERS NETWORK.
Pursuant to the Hearing Officer Order entered June 30, 2009, the Illinois Environmental
Protection Agency
("Illinois EPA" or "Agency") submits the following answers to the pre-filed
questions submitted on behalf of Prairie Rivers Network ("PRN") by Traci L. Barkley, Water
Resources
Scientist. PRN's questions II through IS are directed to the Agency. The questions
and the Agency's answers are
as follows:
11.
Section 840.114 Groundwater Monitoring Program. (a) "The owner and
operator
of Ash Pond D must monitor .... : 35 III. Adm. Code 620.410(a) and
(d) except radium-226 and
radium-228." Why are these two constituents
excluded?
Based on research conducted by the United States Geological Survey ("USGS"), radium
and other radioactive elements in coal
ash are not significantly elevated above concentrations
that occur in materials found naturally in the environment. The
USGS also found that dissolved
concentrations
of these radioactive elements are below levels of health concern. Therefore, the
inclusion
of Radium 226 and Radium 228 is not warranted. This information can be found in
USGS Fact Sheet FS-163-97, October 1997, provided as Attachment I to this document.
12.
Per Section 3.135 (a)(9)(B), "CCB shall not exceed Class I Groundwater
Standards for metals when tested utilizing test method ASTM D3987-85. The
sample or samples tested shall be representative of the CCB being considered
for use." Why isn't this requirement referenced under Section 840.124?
Section 3. 13S(b) of the Act (41S ILCS S/3.13S(b» allows coal combustion waste
I

("CCW") to be used beneficially without meeting the metals standards established in Section
3.
I
35(a-5)(B), if the applicant demonstrates to the Agency that three criteria will be met:
I)
The use
of the CCW will not cause, threaten or allow the discharge of any contaminant into the
environment; 2) the use will otherwise protect human health and safety and the environment; and 3)
the use constitutes a legitimate use
of the CCW as a raw material that is an effective substitute for an
analogous raw material. Ameren originally proposed, in effect, that the CCB detenmnation may be
made
in this site-specific context, and the Agency has concurred with this approach. Ameren' s
Original Proposal at §
840.
I
24(c); Agency's Proposed Amendments at § 840.
I
24(d)(4).
The Agency believes the use
of CCW to create the slope for the final cover system
constitutes a legitimate use
as an effective substitnte for other fill material. The slope itself is
subject to the stability criteria
of35
TIl.
Adm. Code 811.304. The use will not result in discharge of
contaminants to the environment and will otherwise protect human health and safety because the
material will be used
in an engineered application in which it will be placed above the water table
and beneath the final cover system consisting
of a geosynthetic membrane and at least three feet of
soil material. This exceeds the standard for CCB used as structnral fill set forth in Section
3.135(a)(8)
of the Act. Once construction is complete, vegetation must be established to stabilize
the soil layer. The final cover system is subject
to the inspection and maintenance requirements set
forth in Section 840.136. Therefore, the three statutory criteria will be satisfied. The Agency
believes this approach is in substantial compliance with the requirements
of the Act.
13.
Why doesn't the additional use of coal combustion byproduct require an
independent approval pursuant to Section 3.135 of the Act, according to
IEPA's suggested edits to Section 840.124?
Please
see the response to Question 12.
14.
We appreciate [Mr. Nightingale's] request on behalf of the Agency for a
moratorium on additional site-specific rules for closure of coal combustion
2

waste surface impoundments. Can you tell us why, given the fact that new
federal rules regarding the management
of coal combustion wastes are likely
forthcoming, the Agency
is not requesting that Ameren's Hutsonville Pond D
activities also be placed on hold?
As stated in Mr. Nightingale's testimony, the Agency has requested that the Pollution
Control Board
("Board") consider a moratorium on proceeding with additional proposals for site-
specific closures
of CCW surface impoundments pending clarification of widely anticipated
federal rules for the management
of CCW and their effect, if any, on the closure of existing
CCW impoundments. If federal rules do not address the closure of existing ash ponds, it may be
appropriate to proceed with a generally applicable rule for ash ponds
in Illinois. The reason the
Agency
has not requested that Ameren's proposal be included within a moratorium is that
Ameren filed its proposal with the Board and
it
was accepted for hearing before the Agency
clarified its
0\\'Il
position on the matter. The Agency's position initially arose out of its
difficulties in finding the resources to assemble a workgroup to respond to Ameren's proposal.
Ameren took Ash Pond D out
of service in 2000 and has pursued closure intermittently
since that time. The absence
of clearly applicable closure requirements along with
disagreements between Ameren and the Agency conceruing the proper approach have been the
causes
of significant delays. The interaction between Ameren and the Agency ultimately
resulted
in the adjusted standard proceeding filed by Ameren in August 2008.
In the Maller of:
Petition
of Ameren Energy Generating Company for Adjusted Standards from
35
Ill. Adm. Code
Parts
811,814,815, PCB AS 09-1 (March 5, 2009). The Board found the landfill rules
inapplicable to surface impoundments and dismissed the adjusted standard proceeding.
It
directed Arneren to file a site-specific rule if
it
wished to pursue the matter.
After the dismissal
of its proposed adjusted standard, 'Ameren moved very quickly to
prepare and file its proposal in this proceeding because
of its stated desire to sell the facility.
3

During this short interval, the Agency did not fully consider the implications of the site-specific
approach
as complicated by the number of similar sites needing closure, the uncertain impacts of
state budget/resource issues, and the additional uncertainty of the outcome of the federal review
ofCCW management. The Agency's decision
to request the moratorium did not come until well
after the proposal had been filed with the Board and accepted. While the policy reasons for the
moratorium are compelling, the
legal gmunds for taking such action with regard to future filings
are uncertain. Requesting that a moratorium apply
so that a previously docketed proceeding
would
be delayed indefinitely or dismissed would raise additional legal issues of retroactivity
and
was never seriously considered by the Agency.
To be clear, the Agency does not object to the site-specific approach itself as a
mechanism
for developing acceptable closure requirements for individual ash ponds. The
Agency believes that will
be accomplished in this proceeding with appropriate amendments to
Ameren's original proposal. Rather, the request for a moratorium is driven by the prospect of70
or more of these proceedings, especially in light of the resource issues and the potential for
conflicts with decisions
to be made at the federal level. Moreover, devoting scarce resources to
the
task of developing and promulgating a statewide rule would be wasteful if the proposal
expected later this
fall makes clear the U.S. EPA intends to regulate this activity pursuant to
federal law.
15.
IfUSEPA redetermines coal combustion waste to be "hazardous" in nature
per
ReRA,
would Subchapter c, Part 724 regulations governing standards
for hazardous waste treatment, storage and disposal facilities
be sufficient to
govern the closure of Ameren's Hutsonville Pond D?
With all due respect, the federal approach suggested by the question is beyond the
scope
of this proceeding, and the Agency workgroup has not evaluated its sufficiency.
Further, the Agency has
no knowledge of the U.S. EPA's intentions beyond published
4
Electronic Filing - Received, Clerk's Office, September 22, 2009

speculation and has made no formal
~valuation
of such an approach. The Agency
expects that any federal proposal will be published for comment in the
Federal Register.
If
so, the Agency will very likely perform an evaluation of the proposal at that time and
submit comments in that forum.

Introduction
Coal Is largely composed of organic matter, but It is the inorganic matter in coal-
minerals and trace elements- that have been cited as possible causes of health,
enVironmental,
and technological problems associated with the use of coal. Some trace
elements in coal are
naturally radioactive. These radioactive elements include uranium (U),
thorium (Th), and their numerous decay products, including radium (Ra) and radon (Rn).
Although these elements are
less chemically toxic than other coal constituents such as
arsenic, selenium, or mercury, questions have been raised concerning possible risk from
radiation.
In order to accurately address these questions and to predict the mobility of
radioactive elements during the coal fuel-cycle, it is important to determine the
concentration, distribution, and form
of radioactive elements in coal and fly ash.
Abundance of Radioactive Elements in Coal and Fly Ash
Assessment of the radiation exposure from coal burning is critically dependent on the
concentration
of radioactive elements in coal and in the fly ash that remains after
combustion. Data
for uranium and thorium content in coal is available from the u.s.
Geological Survey (USGS), which maintains the largest database of infor-mation on the
chemical composition
of U.S. coal. This database is searchable on the World Wide Web at:
http://energy.er.usgs.gov/Droducts/databases/ CoaIOuaJ/intro.htm. Figure 1
displays the frequency distribution
of uranium concentration for approximately 2,000 coal
samples from the Western United States and approximately
300 coals from the Illinois
Basin. In the majority
of samples, concentrations of uranium fall in the range from slightly
below 1 to 4 parts per million (ppm). Similar uranium concentrations are found
in a variety
of common rocks and soils, as indicated in figure 2. Coals with more than 20 ppm uranium
are rare in the United States. Thorium concentrations in coal
fall within a similar
1-4
ppm
range, compared to an average crustal abundance of approximately 10 ppm. Coals with
more than
20 ppm thorium are extremely rare.
During coal combustion most
of the uranium, thorium, and their decay products are
released from the original coal
matrix and are distributed between the gas phase and solid
combustion products.

URANIUM CONCENTRATION (ppm)
The partitioning between gas and solid is
controlled by the
volatility and chemistry of
the individual elements. Virtually 100
percent of the radon gas present in feed
coal is transferred
to the gas phase and is
lost in stack emissions.
In con-trast, less
volatile elements such as
thorium, uranium,
and the majority of their decay products are
almost
entirely retained in the solid
combustion wastes. Modern
power plants
can recover greater than 99.5 percent of the
solid combustion wastes. The average ash
yield
of coal burned in the United States is
approximately 10 weight percent. Therefore,

the original coal. Figure 2 illustrates that the
uranium concentration of most fly ash (10 to 30 ppm) is still in the range found in some
granitic rocks, phosphate rocks, and shales. For example, the Chattanooga Shale that
occurs in a large portion of the Southeastern United States contains between 10 and 85
ppm U.
Forms of Occurrence of Radioactive Elements in Coal and Fly Ash
The USGS has a current research project to investigate the distribution and modes of
occurrence (chemical form) of trace elements in coal and coal combustion products. The
approach typically involves
(1) ultra sensitive chemical or radiometric analyses of particles
separated on the basis of size, density, mineral
or magnetic properties, (2) analysis of
chemical extracts that selectively attack certain components of coal or fly ash, (3) direct
observation and microbeam analysis
of very small areas or grains, and (4) radiographic
techniques
that identify the location and abundance of radioactive elements.
Most
thorium in coal is contained in common phosphate minerals such as monazite or
apatite. In contrast, uranium is found in both the mineral and organic fractions of coal.
Some uranium
may be added slowly over geologic time because organic matter can extract
dissolved uranium from ground water. In fly ash, the uranium is more concentrated in the
finer sized particles. If during coal combustion some uranium is concentrated on ash
surfaces as a condensate,
then this surface-bound uranium is potentially more susceptible
8

to leaching. However, no obvious evidence of surface enrichment of uranium has been
found
in the hundreds of fly ash particles

he above observation is based on the use
of fission-track radiography, a

Health and Environmental
Impact of Radioactive Elements Associated With Coal Utilization
Radioactive elements from coal and fly ash may come in contact with the general public
when they
are dispersed in air and water or are included in commercial products that
contain fly ash.
.
The radiation hazard from airborne emissions
of coal-fired power plants was evaluated in
a series of studies conducted from
1975-1985.
These studies concluded that the maximum
radiation dose to an individual living within
1 km of a modern power plant Is equivalent to a
minor, perhaps
1
to
5
percent, increase above the radiation from the natural environment.
For the average citizen, the radiation dose
from coal burning is considerably less.
Components of the radiation environment
that impact the U.S. population are illustrated in
figure 4. Natural sources account
for the majority (82 percent) of radiation. Man-made
sources of radiation are dominated by medical
X-rays (11 percent). On this plot, the
average population dose attributed to coal burning is included under the consumer products
category and
is much less than 1 percent of the total dose.
Fly ash is commonly used as an additive to concrete building products, but the
radioactivity
of typical fly ash is not significantly different from that of more conventional
concrete additives
or other build-Ing materials such as granite or red brick. One extreme
calculation
that assumed high proportions of fly-ash-rich concrete in a residence suggested
a dose enhancement, compared to normal concrete,
of 3 percent of the natural
environmental radiation.
Another consideration
is that low-density, f1y-ash-rich concrete products may be a
source
of radon gas. Direct measurement of this contribution to Indoor radon is complicated
by the much larger contribution from underlying soil and
rock (see fig. 4). The emanation of
radon gas from fly ash is less than from natural soil of similar uranium content. Present
calculations indicate
that concrete building products of all types contribute less than
10
. percent of the total indoor radon.
9

Approximately three-fourths of the annual
production of fly ash is destined for disposal in
engineered surface impoundments and landfills, or in
abandoned mines and quarries. The primary
environmental concern associated
with these disposal
=:c..=r0n.Ee.",sites is the potential for groundwater contamination.

In lhc U.S. J'tOpulatioo ..
Standardized tests of the leachability of toxic trace
elements such as arsenic, selenium, lead, and mercury
from fly ash show that the amounts dissolved are
sufficiently low to justify regulatory classification of fly
ash as nonhazardous solid waste. Maximum allowable
concentrations under these standardized tests are
100
times drinking water standards, but these concentration
limits are rarely approached in leachates
of fly ash.
The leachability of radioactive elements from fly ash
has relevance in view of the U.S. Environmental
Protection Agency (USEPA) drinking
water standard for dissolved radium (5 picocuries per
liter) and the proposed addition of drinking water standards for uranium and radon by the
year
2000.
Previous studies of radioelement mobility in the enviroment, and in particular, in
the vicinity of uranium mines and mills, provide a basis for predicting which chemical
conditions are likely
to influence leachability of uranium, barium (a chemical analog for
radium), and thorium from fly ash. For example, leachability of radioactive elements is
critically influenced by
the pH that results from reaction of water with fly ash. Extremes of
either acidity (pH<4) or alkalinity (pH>8) can enhance solubility of radioactive elements.
Acidic solutions attack a
variety of mineral phases that are found in fly ash. However,
neutralization of acid solutions by subsequent reaction with natural rock or soil promotes
precipitation or sorption of many dissolved elements including uranium, thorium, and many
of their decay products. Highly alkaline solutions promote dissolution of the glassy
components of fly ash that are an identified host of uranium; this can, in particular, increase
uranium solubility
as uranium-carbonate species. Fortunately, most leachates of fly ash are
rich in dissolved sulfate, and
this minimizes the solubility of barium (and radium), which
form highly insoluble sulfates.
Direct measurements
of dissolved uranium and radium in water that has contacted fly
ash are limited to a small number of laboratory leaching studies, including some by'USGS
researchers, and sparse data for natural water near some ash disposal sites. These
preliminary results indicate
that concentrations are typically below the current drinking
water standard for radium (5 picocuries per liter) or the initially proposed drinking water
standard for uranium of
20
parts per billion (ppb).
Summary
Radioactive elements in coal and fly ash should not be sources of alarm. The vast
majority of coal and the majority of fly ash are not significantly enriched in radioactive
elements,
or in associated radioactivity, compa red to common soils or rocks. This
observation provides a useful geologic perspective for addressing societal concerns
regarding possible radiation and radon hazard.
The location and
form of radioactive elements in fly ash determine the availability of
elements for leaching during ash utilization or disposal. Existing measurements of uranium
distribution in fly ash particles indicate a uniform distribution of uranium throughout the
glassy particles. The apparent absence of abundant, surface-bound, relatively available
uranium suggests that the rate of release of uranium is dominantly controlled by the
relatively slow dissolution of host ash particles.
Previous studies of dissolved radioelements in the environment, and existing knowledge
of the chemical properties of uranium and radium' can be used to predict the most important
10

chemical controls, such 'as pH, on solubility of uranium and radium when fly ash interacts
with water. Limited measurements
of dissolved uranium and radium in water leachates of
fly ash and in natural water from some ash disposal sites indicate that dissolved
concentrations
of these radioactive elements are below levels of human health concern.
