1. Introduction

Commenters have raised concerns about the statistical basis and calculations used to develop the 

limitations and standards. This essay summarizes and responds to these comments. 

Section 2 addresses comments that percentiles of statistical distributions, such as the 99th 

percentile, do not reflect the entire range of variability that can be expected in the discharges 

from well-designed, well-operated facilities; and that therefore some relief should be provided to 

facilities in the form of higher limitations and standards or a formal policy that allows periodic 

exceedance of the limitations and standards. The issue raised by comments is not unique to this 

rule. It has in fact been raised in comments on many other effluent guideline rulemakings 

throughout the history of the regulatory program. Moreover, it has been the subject of many 

lawsuits in various United States Circuit Courts of Appeals. EPA’s approach has been upheld, 

notably in CMA v. U.S. EPA, 870 F.2d 177 (5th Cir. 1989) and NWF v. EPA, 286 F.3d 554 

(D.C. Cir. 2002).

The other sections address comments that were less frequently included in comments. Section 3

describes EPA’s data reviews and assumptions, including its baseline substitution for nondetected measurements. Section 4 addresses EPA’s choice of the modified delta-lognormal 

distribution, including adjustments for positive autocorrelation, to model the data. Section 4 also 

describes EPA’s evaluation of alternative statistical approaches. Section 5 discusses the 

Agency’s policy on compliance with the limitations.

In this essay, the term ‘limitations’ or ‘effluent limitations’ also refers to the standards 

established by today’s rulemaking.

2. Definitions of Limitations

The limitations in this rulemaking are numerical values that are bounds on the amounts of 

pollutants that may be discharged and are, in effect, measures of how well the production 

processes and wastewater treatment systems must be operated. These limitations are a critical 

because they form the foundation for enforceable effluent limitations. In the course of 

developing effluent limitations guidelines and standards, EPA uses data on pollutants from 

facilities employing the appropriate level of control technologies to determine limitations. 

Although the regulations do not require that any particular technology be installed, they require 

plants to achieve effluent limitations that are based on the proper operation of the model 

technologies. NWF at 558.

The limitations in today’s rulemaking are intended to reflect vigilant control of discharges, 

including controlling sources of variability at well operated facilities. EPA recognizes that these 

limitations may require some dischargers that are generally good performers to improve their 

process controls and/or treatment system operation and maintenance so that they are always good 

performers. EPA considers such a requirement is consistent with the statutory requirement that

discharge limitations reflect the best available technology economically achievable or the best 

available demonstrated technology. 

Two types of limitations (or standards) for continuous dischargers are contained in these effluent 

guidelines regulations: daily maximum limitations and monthly average limitations. The 

primary goal of these limitations is for the facility to design to meet the long term average, but 

also to make sure the facility is always employing treatment technology that represents the 

appropriate level of control. 

The first type of limitation is the daily maximum limitation which is a restriction on the amount 

of pollutant in any one daily sample. The definition provided in 40 CFR § 122.2 states that a 

daily discharge is the “‘discharge of a pollutant’ measured during a calendar day or any 24-hour 

period that reasonably represents the calendar day for purposes of sampling.” The daily 

maximum limitation is either (1) an estimate of the 99th percentile of the distribution of the daily 

measurements (which is based on the product of a variability factor and a long-term average); or 

(2) expressed as the minimum level of the analytical method (as is the case for the rule’s arsenic 

limitation). 

The second type of limitation is the monthly average limitation which is a restriction on the 

average of daily measurements taken during a month. The monthly average limitation is the 

estimate of the 95th percentile of the distribution of the monthly averages of the daily 

measurements. This percentile is estimated using the product of the long-term average and 

variability factor. (In some instances, a monthly average limitation was not established because

the corresponding daily maximum limitation was established at the quantitation level for nondetected observations.)

This section describes EPA’s approach to determining appropriate limitations based on 

percentiles; explains that the statistical methodology is a framework for developing those 

limitations; describes EPA’s rationale in selecting percentiles as the basis for those limitations; 

and describes EPA’s approach to developing the arsenic daily maximum limitation when all 

observations are non-detected.

2.1 Limitations Based Upon Percentiles of Distributions

Consistent with longstanding practice in the effluent guidelines program, EPA determines a 

limitation (or standard) based on percentiles in two basic steps. This procedure recognizes the 

variable nature of production processes and wastewater treatment systems inherent even at 

facilities that are well-designed and operated. 

In the first step, EPA determines an average performance level (the “long-term average”) that a 

facility with well-designed and operated model technologies (which reflect the appropriate level 

of control) is capable of achieving. This long-term average is calculated from the data from the 

facilities using the model technologies as explained in TDD Section 13. EPA expects that all 

facilities subject to the effluent limitations in question will design and operate their production 

processes and treatment systems to achieve the long-term average performance level on a 

consistent basis because facilities with well-designed and operated model technologies have

demonstrated that this can be done. 

EPA recognizes, however, production and wastewater treatment are complex and variable 

processes, especially at large, highly integrated industrial facilities. EPA further recognizes that 

the wastewater generated by such facilities exhibits considerable variation in pollutant 

concentrations when processed through extensive and well-designed systems. EPA also 

recognizes that there are other sources of variability such as sampling and analytical variability 

(see Section 3.1 for further discussion of the different sources). Therefore, in the second step of 

developing a limitation, EPA determines an allowance for all of these sources of variability. This 

variability is incorporated into the limitations through the use of the variability factors. EPA then 

multiplies the long-term average by the variability factor to obtain the limitation which is an 

approximation of the percentiles described in the next section.

Because the variability factors for this rule were derived from facilities employing the 

technologies representing the appropriate level of control (BAT or BADCT), the limitations 

account for a level of variation that is within the capability of an individual facility to control. If 

a plant is designed and operated to achieve the long-term average on a consistent basis, and if the 

facility maintains adequate control of process and treatment variation, the allowance for 

variability provided in the limitations is sufficient. In other words, today’s effluent limitations 

already account for any reasonable variability likely to occur at well-operated facilities 

implementing technologies representing the appropriate levels of control.

2.2 Statistical Methodology is a Framework for Limitations 

Development

The statistical methodology is used as a framework to establish limitations that facilities are 

capable of complying with at all times. The limitations were never intended to have the rigid 

probabilistic interpretation (i.e., that a pre-set proportion of violations are expected) as suggested 

by comments in this and other rulemakings. Statistical methods are appropriate for dealing with 

effluent data because the quality of effluent, even in well-operated systems, is subject to a certain 

amount of random fluctuation or uncertainty. Statistics is the science of dealing with uncertainty 

in a logical and consistent manner. Statistical methods, therefore, provide a logical and consistent 

framework for analyzing a set of effluent data and determining values from the data that form a 

reasonable basis for effluent limitations. EPA has done a reasonable job in developing the 

limitations and demonstrating their achievability. Statistical methods provide a critical part of the 

framework of the development process that establishes the reasonableness of the limitations.

2.3 Selection of Percentiles

EPA must exercise its judgment to select a limitation which encompasses virtually all the 

potential reasonable variability within the control of the facility and yet is not so high as to be 

meaningless as a regulatory control device. EPA calculates limitations based on percentiles using 

the products of the long-term averages and variability factors. The chosen percentiles are 

intended, on one hand, to be high enough to accommodate reasonably anticipated variability 

within control of the facility and, on the other hand, to be low enough to reflect a level of 

performance consistent with the Clean Water Act requirement that these effluent limitations be 

based on the “best available technology economically achievable” and “best available

demonstrated control technology.” EPA has used an estimate of the 99th percentile of the 

distribution of the daily measurements as the basis for daily maximum limitations and standards 

for a number of years and numerous courts have upheld EPA’s approach. EPA has selected high 

but not unusually high percentiles as the basis for daily maximum and monthly average 

limitations and standards and no court has ever required EPA to base effluent limitations on a 

higher percentile level than that chosen by EPA. To the contrary, several Circuit Courts of 

Appeal have explicitly rejected the suggestion that EPA do so. Even the Ninth Circuit in 

Marathon Oil (564 F.2d 1272-74 (9th Cir. 1977)), while endorsing the need for an upset 

provision, specifically rejected the notion of an elevated percentile limitation. The Court pointed 

out that an overly high limitation would be “worthless as a control standard.” Indeed, most 

Circuit Courts considering the question have rejected the argument that any relief other than 

prosecutorial discretion is required to address the “problem” created by EPA’s use of percentiles 

such as 99. See Chemical Manufacturers Association v. U.S. Environmental Protection Agency, 

870 F.2d 177, 230 (5th Cir. 1989); Weyerhaeuser Co. v. EPA, 590 F.2d 1011, 1056-1058 (D.C. 

Cir. 1978); Corn Refiners Association Inc. v. Costle, 594 F.2d 1223 (8th Cir. 1979); United 

States Steel v. Train, 556 F.2d 822, 841-842 (7th Cir. 1977); CPC International, Inc. v. Train, 

540 F.2d 1329, 1336-1338 (8th Cir. 1976); American Petroleum Institute v. EPA, 540 F.2d 1023, 

1035-36 (10th Cir. 1976).

The API court stated:

The whole problem of variability factors presents a practical effort to 

accommodate for variations in plant operations. As technology for control 

of pollutant discharges improves, the variations should lessen. The choice 

of statistical methods lies within the sound discretion of EPA. EPA has 

acted properly and reasonably in establishing the variability factors before 

us.

EPA has determined, as a matter of policy, that the 99th percentile of the distribution of daily 

measurements is an appropriate basis for daily maximum limitations and standards in effluent 

guidelines rulemakings. EPA considers this to be a reasonable determination of “best available 

technology” or “best available demonstrated technology” because the resulting limitations and 

standards are based on operators designing and planning to meet a level of performance 

commensurate with “best” while also accounting for variability in optimally performing 

processes and treatment systems. In other words, if EPA used a higher value percentile, then the 

ultimate limit would not reflect the appropriate level of control. This policy of using the 99th 

percentile as a basis has been adhered to in developing daily maximum limitations and standards 

in effluent guidelines rulemakings for many years. In 1976, the Court in API, supra, 540 F.2d 

1023, 1035-36 (10th Cir. 1976) identified the daily variability factor “‘as the 99th percentile 

probability of occurrence value divided by the mean.’ The result is ‘the multiplier by which the 

long-term achievable values must be multiplied in order to derive the value not permitted to be 

exceeded.’” The definition and use of the daily variability factor is the same in today’s rule. The 

API Court then rejected the refineries’ argument: “Because EPA selected the 99th percentile, the 

refineries say that they must be afforded at least four days a year, 1% of 365, when they may 

make excess discharges without fear of penalty. The reasoning does not impress us.”

Many comments in effluent guidelines rulemakings have questioned EPA’s use of an estimate of 

the 95th percentile of the distribution of the monthly averages of the daily measurements for the 

monthly average limitations. EPA has determined, as a matter of policy, that the 95th percentile 

was a more appropriate choice for monthly average limitations in all industrial effluent 

guidelines rulemakings because the variability of monthly averages is less than the variability of 

individual daily measurements. This policy has been followed in developing monthly average 

limitations in all effluent guidelines rulemakings since 1987. Comments on rulemakings often 

assert that compliance monitoring should allow for five percent exceedance of the monthly 

average limitation. For example, comment 70 of DCN EPA-HQ-OW-2009-0819-4499-A1 

provides a similar objection stating that “...by definition, the effluent level can be expected to 

exceed the limit 1 in 20 months, on average, just by chance when a plant is in control.” EPA 

disagrees with this assertion as discussed below.

EPA’s rationale for its policy decision to use the 95th percentile for monthly average limitations 

is related to the roles of the long-term averages, the daily maximum limitations, and the monthly 

average limitations in controlling pollutant discharges. Facilities should operate their 

technologies in a manner that can achieve the long-term average on a consistent basis while 

adequately controlling for variation in processes and treatment systems. Rather than setting a 

limitation that would require continuous dischargers to achieve the long-term average over a 

specified period of time (such as a year), EPA chose to establish daily and monthly limitations 

that would require facilities to demonstrate that the discharges are controlled on a daily and 

monthly basis.

In establishing daily maximum limitations, EPA’s objective is to restrict the discharges on a 

daily basis at a level that is achievable for a facility controlling its discharges at the long-term 

average. EPA acknowledges that variability around the long-term average results from normal 

operations. This variability means that occasionally most facilities may discharge at a level that 

is quite a bit greater than the long-term average. (This variability also means that most facilities 

may occasionally discharge at a level that is considerably lower than the long-term average.) To 

allow for these possibly high daily discharges on a daily basis, EPA has established the daily 

maximum limitation to be the 99th percentile of the daily values. A facility that discharges 

consistently at a level near the daily maximum limitation would not be controlling its discharges 

around the long-term average which is part of EPA’s objective in establishing the daily 

maximum limitations. Such a facility would be considered in compliance as long as discharges 

were less than the daily maximum limitation. However, operating processes and treatment 

systems to consistently achieve a level close to the limitation is poor practice because even a 

relatively small amount of variability would result in a high rate of non-compliance with the 

daily maximum limitation.

In establishing monthly average limitations, EPA’s objective is to provide an additional 

restriction that supports EPA’s objective of having facilities control their average discharges at 

the long-term average. The monthly average limitation requires continuous dischargers to 

provide on-going control, on a monthly basis, that complements controls imposed by the daily 

maximum limitation. In order to meet the monthly average limitation, a facility must 

counterbalance a value near the daily maximum limitation with one or more values well below 

the daily maximum limitation. To achieve compliance, these values must result in a monthly

10-8

average value at or below the monthly average limitation. 

As a basis for the monthly average limitation, EPA considers the 95th percentile of the 

distribution of the monthly averages more appropriate than some larger percentile, such as the 

99th percentile. EPA has decided that it is unnecessary to provide an allowance for extreme 

monthly averages similar to the allowance provided by using the 99th percentile for extreme 

daily discharges. Compliance with the daily maximum limitation is determined by a single daily 

value; therefore, EPA has decided that the 99th percentile provides a reasonable basis for the 

daily maximum limitation by providing an allowance for an occasional extreme discharge. 

However, for this rulemaking, compliance with the monthly average limitation is determined by 

the average of multiple measurements (number of measurements per month typically depends on 

the pollutant being regulated). Because compliance is based upon more than one daily 

measurement, EPA has decided that facilities should be capable of controlling the average of 

daily discharges to avoid extreme monthly averages above the 95th percentile. By requiring 

facilities to avoid extreme monthly averages, more facilities are likely to design and operate their 

processes and treatment systems around the long-term average (which is EPA’s objective).

2.4 Use of Median for Long-Term Average Basis of Limitation

EPA disagrees with assertions in comments' assertions that use of a mean (or arithmetic average) 

would be more appropriate than the median in calculating the long-term averages in developing 

limitations. The median is the value at which half of the observed episodes will be above and 

half will be below. In this manner, all values, not just one or two episodes, contribute to the 

determination of the long-term average (LTA). The midpoint is precisely that: half of the episode 

long-term averages are higher than the median, and half are lower. As a measure of central 

tendency, the median tends to ameliorate the effects that extreme values, high-end as well as 

low-end, can have on the average. 

It is not true that EPA's use of a median for the option long-term average will result in “1-in-4 [or 

1-in-2] chance that the sample minimum and maximum LTAs bracket the true median LTA.” 

(DCN EPA-HQ-OW-2009-0819-4655-A18, Comment Excerpt #25 (in Comment Code #31.h). 

EPA disagrees that it is necessary for facilities selected as the basis of a limitation to have similar 

means and/or variance. The implication is incorrect that facilities and/or data must somehow be 

from the same population as a necessary condition for use in calculating the option long-term 

average and variability factor. The Agency has combined episode-level values from facilities 

with appropriate, well operated treatment technology to define the overall regulatory values. 

Because these facilities are well operated, they provide valid information concerning welloperated treatment systems and combining their values has the effect of giving appropriate 

weight to each of them in determining overall values. 

2.5 Daily Maximum Limitation is Consistent with Statistical Framework

EPA is establishing certain effluent limitations equal to the detection limit1for the effluent data 

 

1 As used here to describe these effluent limitations, the term “detection limit” refers to the 

quantitation limit (QL), not the minimum detection level (MDL).

10-9

that were used to develop the limitations because all observations were non-detects. This is the 

case for the arsenic daily maximum limitation established for discharges of gasification 

wastewater from new and existing sources, which is based on evaporation. This is also the case 

for arsenic and selenium daily maximum effluent limitations for discharges of FGD wastewater 

from new sources and for discharges from existing sources under the voluntary incentives 

program, which are based on the combination of chemical precipitation, softening and 

evaporation. As it has for the other regulated pollutants, EPA established these daily maximum

limitations based on data in the record indicating that the limitations reflect the appropriate level 

of control. The Agency is establishing the limitations based on the observed performance of 

facilities operating the model technologies. In addition, the Agency notes that the model 

technologies vaporize the wastewater, leaving behind nonvolatile constituents such as arsenic. 

The limitation applies to the cooled water vapor which, as a result of the vaporization process, 

does not contain measurable levels of arsenic in gasification wastewater, or of arsenic and 

selenium in FGD wastewater. 

Although the Agency’s has an historical practice of setting effluent limitations based on 99th 

percentile estimates from the probability distribution of daily values, this is not a requirement 

under the Clean Water Act. The Agency has discretion with regard to demonstrating the 

technological achievability of limitations for the model technologies selected as the basis for 

limitations. Historically, the Agency has shown that limitations are unlikely to be exceeded 

because the 99th percentile is used as a basis for the variability factor used in developing the 

daily maximum limitation. The Agency has demonstrated that the limitations discussed here are 

achievable in the sense that measurement results for wastewater obtained from well operated and 

maintained evaporation processes are unlikely to exceed the detection limit. EPA considers such 

limitations appropriate for data that are entirely non-detected measurements. Effluent limitations 

provide a reasonable allowance for the variability that exists when appropriate treatment 

processes are well operated and maintained and laboratories follow the appropriate procedures in 

analyzing the samples. For this rule, EPA considers the arsenic limitation for gasification 

wastewater, and for arsenic and selenium in FGD wastewater, provide a reasonable allowance 

for the variability that exists when evaporative processes are well operated and maintained 

because of the data from the model technology have demonstrated that the process results in 

measurements below detection. Thus, EPA concludes that the limitations are supported. 

Furthermore, modeling of the data using the statistical approaches is not required.

3. Data Review and Assumptions

As part of developing the limitations, EPA reviewed all of the data that it received and collected 

to verify that the data represent the performance level that well-designed and operated model 

technologies can achieve. This section describes data issues including the sources of variability; 

evaluation of the data; use of averaged measurements; statistical outliers; exclusion of time 

periods; baseline value substitution; and pooling of data. 

3.1 Data Include All Sources of Variability

All data collected by EPA and used to determine limitations and standards contain many 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-10

components of variability, and any process used to analyze these data, such as the methodology 

used to determine limitations and standards, entrains the variability inherent in the data. The 

result is that any value determined from these data, such as an effluent limitation or standard, 

contains the variability inherent in the data from which it is derived.

The effluent data from a particular plant contain many components or sources of variability. This 

may be illustrated by the following equation:

V (total) = V(day) + V(season) + V(sampling) + V(shipping) + 

V(storage) + V(analytical) + V(other)

where,

V(total) is the total variability in the data

V(day) is the daily variability

V(season) is the seasonal variability (winter, spring, summer, fall)

V(sampling) is the sampling variability; i.e., variability in the physical process of 

obtaining the sample

V(shipping) is the variability due to variation in shipping conditions

V(storage) is the variability due to variation in sample storage conditions

V(analytical) is the variability due to the analytical or measurement process

V(other) are other, unknown or unaccounted for sources of variability

In producing effluent limitations and standards, EPA does not attempt to determine the 

contribution of each component of variability to the total, for two reasons: (1) the studies EPA 

conducts would need to be structured differently to determine each individual component. 

Special studies would have to be conducted and additional data would have to be collected and 

analyzed to address each component of variability of interest. For example, if EPA wished to 

determine the shipping component of variability, EPA would need to evaluate all means of 

sample shipping used (airplane, helicopter, truck, train, bus, other) and the shipping conditions 

(temperature, pressure); and (2) All components of variability are included in the total. Because 

samples are collected at various plants on various days during various seasons and are shipped 

by various means to various laboratories and stored at various temperature for various times, and 

are analyzed by various analysts in various laboratories, all of these sources of variability are 

inherent in the total variability of the data. It is unnecessary (and very expensive and time 

consuming) to conduct the studies, collect and analyze the data necessary to separate and 

estimate each component of variability because the effluent limitation or standard was developed 

taking this variability into account. Furthermore, there would always be some portion of 

variability that cannot be specifically identified.

The effect of sources of variation in measured pollutant values, i.e., the available data, can be 

illustrated as follows. If an observed or measured value of a pollutant in a sample is denoted by 

X then

X = T + D

where

T = the true, actual amount of the pollutant present in the sample

and

D = discrepancy in the measured value that represents the difference between the true 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

10-11

amount and the measured amount.

The X values constitute the information available to the Agency to define what is in wastewater 

samples and assess treatment performance. The sources of variability cited above cause the 

measured values to deviate from the true amount T; these deviations are represented by D. Only 

one of these sources of variability is due to analytical variability. However, whatever the sources 

of variability that contribute to D and whatever the magnitude of D, it is incorporated into the X 

or measured values and any calculations performed with the X values. Because the limitations 

and standards are calculated from the X values resulting from analytical methods approved for 

NPDES purposes, all sources of variability that are in the measured values are incorporated into 

the limitations and standards that are calculated from the measured values. Since the values of D 

and T are not known for any given measured value, it would not be appropriate to provide an 

allowance for D or any component of it such as the analytical component. However, it should be 

noted that the net effect of the sources of variability can cause either positive or negative 

departures from the true amount in the individual measured values. The Agency can state 

unequivocally that analytical variability is one of many inherent components of variability in all 

measurements used for this rulemaking, and therefore, that analytical variability, along with the 

other sources of variability, has been taken into account in the development of limitations 

through data.

The greater the variability from any of these sources or any other source, the higher the 

variability factor and the higher the effluent limit. Therefore, the process for developing an 

effluent limit is self-correcting, in that an increase in error or variability in the data, regardless of 

the source, results in an increase in the effluent limit. Additional allowance for any particular 

source of variability such as analytical or laboratory error is not warranted.

EPA has not incorporated an allowance for inter facility or between facility variability because it

represents sources of variation that are not controllable at individual facilities. In complying with 

the limitations based upon the model technologies, a given facility need only control its own 

discharges and does not need to consider the discharges by any other facility.

3.2 Evaluation of Data

The Agency considers facility level performance to be a critical factor in determining overall 

standards and, thus, uses facility level data from as many facilities as are available. EPA 

completed its detailed study in 2009 and repeatedly requested the industry to provide data for the 

model technologies and explained its rationale for requesting the data. EPA has used all of the 

available relevant data including the long-term data provided by the industry and evaluated the 

data to ensure that the pollutants were present in the influent at sufficient concentrations to 

evaluate treatment effectiveness at the facility in this rulemaking. Thus, EPA has used all of the 

relevant, available data. 

3.2.1. Available Data

A number of comments questioned the use of few facilities and number of data points for the 

determination of the limitations and standards. There is no question that the Clean Water Act 

specifically authorizes EPA to base limitations and standards on the performance of a single 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

facility. It is well-established that BAT may represent the best performance in the industrial 

category and thus, it is not unusual for EPA to base effluent limitations on data from a single 

facility. For example, in the OCPSF guideline, EPA based 38% of the limitations on the 

performance of a single facility. EPA develops effluent limitations and standards on the basis of 

data from facilities using BAT technology. The Agency uses available data that meets the data 

acceptance criteria to the extent it can in order to incorporate the data into its analyses for 

decision making on the rule. EPA’s approach is reasonable. Courts have recognized that EPA 

must operate with available data. See e.g., BASF Wyandotte Corp. v. Costle 598 F.2d 637, 652-

653 (1st Cir. 1979) where the Court stated that:

Given this admitted information shortage EPA must make use of the information it has, 

recognizing the limits of the information; EPA cannot refuse to carry out its mandate, 

waiting for the day when it might possess perfect information . . . The same answer 

applies to petitioners’ claim that the data . . . were too sparse to support any conclusion 

about their effectiveness . . . EPA used all the data it could accumulate. Had the industry 

come forward with more data there is every indication that EPA would have used it . . . It 

was up to EPA to decide whether the limited data base was sufficient to support the 

conclusions reached. We hold that deciding to base conclusions on the limited data 

available was a reasonable exercise of discretion given the regulatory mandate.

EPA disagrees with comments that its data sets are not "statistically representative" and cannot 

predict future discharges or variability. In fact, small samples of good performance can result in 

useful estimates of treated effluent quality. Estimates of the necessary parameters for the 

lognormal distribution can be calculated with as few as two distinct detected values in a data set 

(in order to calculate the variance, two distinct detected values are the minimum number that can 

be used to obtain an estimate of the variance). Also see Essay Section 5.

3.2.2. Representativeness of the Data

Comments asserted that the data were not representative. EPA conducted sampling at facilities 

that were determined by EPA to be performing the model treatment technology. Further, via 

thorough engineering review, EPA determined that data from those facilities, as well as certain

data supplied by the industry, to be representative of the model technology. Based on this 

technical review, EPA excluded data points that were not representative of the normal treatment 

process. Prior to conducting the sampling episodes, EPA confirmed with the facilities that the 

wastes treated during EPA’s sampling episode were representative of waste treatment processes

overall at these facilities. Moreover, no comments provided any justification or specific details to

support the view that the wastes treated at the model facilities were not representative of wastes 

treated throughout the industrial category in terms of process or treatment system characteristics, 

concentrations, variation in discharges, time periods, seasons, or other factors.

3.3 Use of Averaged Data

In general, the Agency does not consider multiple analysis results collected within a single day, 

such as a grab sample and its duplicate sample, should be treated as separate independent values

in limitations calculations. This practice would not be consistent with NPDES regulations and 

would introduce potential sources of variation that are not generally appropriate for inclusion in 

effluent limitations. The Agency's approach of averaging multiple analytical results for the same 

facility, sampling site, sampling date and pollutant is consistent with standard, conventional 

practice in environmental analytical work and gives one day's sampling information appropriate 

weight in determining effluent limitations.

Combining the results for a given day is also consistent with requirements of NPDES regulations 

at 40 CFR § 122.2 which define the daily discharge. For limitations expressed in units other than 

total mass discharged during the day (e.g., concentration units), the daily discharge is the 

"average measurement of the pollutant over the day." In addition, 40 CFR § 122.41(l)(4)(iii) 

requires that “Calculations for all limitations which require averaging of measurements shall 

utilize an arithmetic mean unless otherwise specified by the Director in the permit.”

3.4 Data Exclusions

In developing its limitations, EPA has not applied statistical outlier evaluation, such as excluding 

data outside of four standard deviations as the commenter has done for its data. EPA does not 

consider the commenter’s approach to be necessary for the effluent data used as a basis of the 

limitations; furthermore, EPA does not consider the commenter’s approach appropriate because 

it blindly excludes data values without considering whether they are associated with normal 

process operations. In this manner, the commenter’s approach could lead to underestimating the 

variance. Instead, EPA’s intent is to use as much data as possible in developing the limitations. 

Only data that do not meet the evaluation criteria are disregarded after a rigorous engineering 

evaluation of the plant conditions that are likely to affect effluent discharge levels. 

Comments incorrectly assert that “EPA removed valid data points representing elevated 

concentrations that would be expected in the tails of the distributions.” (e.g., DCN EPA-HQOW-2009-0819-4379-A1, Comment Excerpt #172 (in Comment Code #31)). Contrary to 

comment assertions, EPA did not eliminate any data for the sole reason that they were in the tails 

of the distribution. Consistent with its practice for other industrial guidelines, EPA only 

eliminated data that did not represent the performance of the model technology. See DCN 

SE05733 for EPA’s discussion of data exclusions based upon engineering evaluations. 

EPA notes that the result of consistently using some of the statistical outlier tests or excluding 

data outside, for example, four standard deviations would often be a decrease in variability. EPA 

does not wish to reduce legitimate variability that is inherent in the treatment process. EPA only 

excluded data that were not consistent with proper operation of the model technology. EPA 

considers this approach to be entirely appropriate. These excursion data do not represent the 

typical variability expected from well-designed and operated processes and treatment systems. 

Furthermore, the upset provision in 40 CFR Section § 122.41(n)(2) states that an upset 

constitutes an affirmative defense to an enforcement action if the procedural requirements of 

paragraph (n)(3) are met. Therefore, it would be inappropriate and unnecessary to include data 

that represent upset conditions in developing limitations. Because facilities are not expected to be 

able to comply with the limitations under upset conditions, EPA excludes data from upset 

conditions in developing limitations.
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-14

EPA also excluded data that were not representative of proper process operations or treatment 

control that might not qualify for the upset defense. The upset defense can only be used for 

conditions beyond the discharger’s reasonable control. (For example, operator error would not 

qualify for the upset defense.) EPA considers these exclusions also appropriate as the data do not 

properly represent the capabilities of the technologies that serve as a basis for the limitations. 

Where EPA has excluded data, the record clearly states which data points were excluded and the 

rationale for the exclusion (see DCN SE05733). In essence, if any unexamined performance 

were to qualify for inclusion in the data sets used to develop the limitations, then the ultimate 

limitations would not reflect the appropriate level of control.

3.5 Baseline Value Substitutions

In general, EPA used detected values or sample-specific detection limits (for non- detected 

values) in calculating the limitations.2 However, there were some instances where EPA 

substituted a baseline value for a detected value or a sample-specific detection limit that was 

lower than the baseline value. EPA often takes this approach to account for the possibility that 

certain detected or non-detected results may be at a lower concentration than generally can be 

reliably quantified by well-operated laboratories. This approach is consistent with the way EPA 

has calculated limitations in previous effluent guidelines rulemakings and is intended to avoid 

establishing an effluent limit that could be biased toward a lower concentration than facilities can 

reliably demonstrate compliance with.3 After excluding data as described in Section 3.4, EPA 

compared each reported result to a baseline value. Whenever a detected value or sample-specific 

detection limit (i.e., sample-specific quantitation limit) was lower than the baseline value, EPA 

used the baseline value instead and classified the value as non-detected (even if the actual 

reported result was a detected value). For example, if the baseline value was 5 micrograms/liter 

 

2 For the purpose of the discussion of calculating the long-term averages, variability

factors, and effluent limitations, the term “detected” refers to analytical results measured and

reported above the sample-specific quantitation limit (QL). The term “non-detected” refers to 

values that are below the method detection limit (MDL) and also those measured by the

laboratory as being between the MDL and the QL.

3 For example, if a daily maximum limit were established at a concentration lower than 

the baseline value, although some laboratories may be able to achieve sufficiently low 

quantitation levels, it is possible that typical well-operated laboratories may not be able to 

reliably measure down to that level. In such cases, a facility would not be able to demonstrate 

compliance with the limit. A similar situation could arise with monthly average limitations, 

particularly if the limit is at a concentration near the baseline value. EPA does not intend to 

suggest that the baseline value should be established at a level that every laboratory in the 

country can measure to, or that limitations established for the ELGs must be established 

sufficiently high that every laboratory in the country must be able to measure to that 

concentration; however, it is appropriate to use baseline values that generally can be reliably 

quantified by well-operated laboratories. This approach achieves a reasonable balance that 

establishes limitations that are representative of treatment system performance and protective of 

the environment, while at the same time ensuring that facilities will have adequate access to 

laboratories with the analytical capabilities necessary to reliably demonstrate compliance with 

the limitations.

(μg/L) and the laboratory reported a detected value of 3 μg/L, EPA’s calculations would treat the 

sample result as being non-detected with a sample-specific detection limit of 5 μg/L.

EPA used the following baseline values for each pollutant in the development of the effluent 

limitations for the steam electric rulemaking:

 Arsenic: 2 microgram/liter (μg/L).

 Mercury: 0.5 nanogram/liter (ng/L).

 Nitrate-nitrite as N: 0.05 milligram/liter (mg/L).

 Selenium: 5 microgram/liter (μg/L).

 TDS: 10 milligram/liter (mg/L).

EPA determined the baseline values for mercury, nitrate-nitrite as N, and TDS using the 

minimum levels (MLs) established by the analytical methods used to obtain the reported values 

or a comparable analytical method where an ML was not specified by the method.4 The baseline 

values for arsenic and selenium are based on the results of MDL studies conducted by welloperated commercial laboratories using EPA Method 200.8 to analyze samples of synthetic FGD 

wastewater [CSC, 2013, DCN 03872].

It should be noted that in cases when all concentration values are above the baseline value, then 

the baseline value would have no effect on the concentration values and subsequent limitations. 

Effluent data for mercury and TDS were all above the baseline values; therefore, EPA did not 

substitute any baseline values when calculating limitations for these parameters. The document 

entitled Sampling Data Used as the Basis for Effluent Limitations for the Steam Electric 

Rulemaking [U.S. EPA, 2015, DCN SE06277] provides a list of all the effluent data used to 

calculate the limitations, as well as what the values were adjusted to using baseline substitution.

In addition to calculating the limitations for each pollutant for each technology option adjusting 

for the baseline values shown above, when appropriate, EPA also calculated effluent limitations 

using all the valid reported results (i.e., without substituting baseline values and/or changing the 

classification of the result). As noted above, the reason for substituting baseline values is 

generally to prevent establishing an effluent that could be biased toward a lower concentration 

than facilities can reliably demonstrate compliance with. In baseline substitution, the effluent 

limit is often unchanged but sometimes is adjusted upward slightly. 

To address comments such as “EPA substituted baseline values for reported measurements 

which had the effect of reducing estimated variability factors.” in DCN EPA-HQ-OW-2009-

0819-4379-A1, Comment Excerpt #172 (in Comment Code #31), EPA compared the effect of 

varying its assumptions for the non-detected measurements. For the steam electric ELGs, EPA 

notes that using baseline substitution increases the limitations in a few instances.5 However, EPA 

 

4 The baseline values for mercury and nitrate-nitrite as N are equal to the MLs specified in 

EPA Methods 1631E and 353.2, respectively. The method EPA used to analyze for TDS

(Standard Method 2540C) does not explicitly state a MDL or ML. However, EPA Method 160.1

is similar to Standard Method 2540C and the lower limit of its measurement range is 10 mg/L

(i.e., the nominal quantitation limit). Thus, EPA used 10 mg/L as the baseline value for TDS.

5 This occurs for the selenium limits for gasification wastewater and for FGD wastewater

found that using baseline substitution has the opposite and unexpected effect in certain other 

instances of suppressing the limitations.6 This downward effect on the effluent limit occurs 

because, although the baseline substitution increases the long-term average value slightly, it also 

reduces the variability of the dataset, and the resulting net effect is a lower effluent limit. This 

means that using baseline substitution in such instances would result in a lower effluent limit 

than EPA would otherwise calculate directly from the unadjusted dataset. Because EPA wants to 

ensure that facilities can achieve the effluent limitations established by the rule, EPA evaluated 

both the baseline-adjusted and unadjusted limitations for each technology option and used the 

higher result for the final ELGs. EPA’s comparison of the baseline-adjusted and unadjusted 

effluent limitations is presented in “Statistical Support Document: Effluent Limitations for FGD 

Wastewater, Gasification Wastewater, and Combustion Residual Leachate for the Final Steam 

Electric Power Generating Effluent Limitations Guidelines and Standards” [DCN SE05733]. 

4. Modified Delta-Lognormal Distribution

Any approach to modeling and analyzing the data are approximations. In developing the

limitations for this rule, the Agency selected the modified delta lognormal distribution as the 

most appropriate approach to modeling the effluent data. The following two sections describe 

EPA’s evaluation of the modified delta-lognormal and alternative statistical approaches.

4.1 Selection for Effluent Data

EPA’s experience has shown that daily pollutant concentrations in effluent discharges of a given 

facility generally follow a lognormal distribution. However, for a given pollutant, an effluent 

data set from a typical sampling episode or self-monitoring episode can include a mixture of 

samples with quantifiable (i.e., measurable) concentrations and samples having no quantifiable 

measure of the pollutant. A data set may represent wastewater samples having both high and low 

pollutant concentrations, depending on the situations in which the industrial processes or sources 

generated the pollutant at the time of sampling. In some data sets, the higher and lower 

concentrations manifest themselves into two groups: detected values associated with higher 

sample concentrations, and non-detected values associated with sample concentrations that are 

below the nominal quantification limit of the analytical method. 

To properly handle mixtures of detected and non-detected data generated in such situations, EPA 

has adopted a modification of the delta-lognormal distribution to model pollutant effluent 

concentrations when developing effluent limitations. The modified delta-lognormal distribution 

is appropriate in that it models effluent data as a mixture of detected measurements that follow a 

lognormal distribution and non-detected measurements that occur with a certain probability.

Because the steam electric effluent data contained a mixture of detected and non-detected 

measurements, the modified delta-lognormal distribution is appropriate to use in modeling the 

 

based on evaporation technology. 

6 This occurs for selenium and nitrate-nitrite as N in FGD wastewater (based on 

biological treatment technology) and for arsenic based on chemical treatment technology.

effluent data to develop the limitations. In addition, the modified delta lognormal model has been 

upheld on several occasions in court challenges and has support in peer reviewed literature.1 

In the “original” delta-lognormal distribution model, the discrete portion of the model, 

representing the proportion of non-detected values, consisted of a specified probability (“spike”) 

assigned to a zero concentration value. Because detection limits may differ among the samples 

due to a variety of analytical factors (e.g., detection limits of the lab instruments; sample dilution 

procedures), EPA modified the delta-lognormal model by replacing the discrete, single-valued 

spike by a discrete distribution made up of multiple spikes. Each spike in this modification 

occurs at a distinct observed detection limit. Therefore, because non-detected results are 

represented by their detection limits in this approach, some researchers consider this approach as 

a variation on a substitution method, where non-detected results are assigned some numeric 

quantity for purposes of the analysis.

Some advantages of the modified delta-lognormal model are as follows:

 It explicitly accounts for the assumption that distinct processes can occur in effluent 

streams.

 It overcomes poor fit of substituted concentration values (for non-detects) that may 

impact (censored) lognormal maximum likelihood estimation.

 The mean and variance exist in closed form expressions, and estimates are relatively easy 

to calculate (e.g., does not require any numerical optimizations) and thus estimates are 

based entirely upon the performance data.

4.1.1. Autocorrelation Correction

The limitations (except arsenic limitations described in Section 2.5) include an adjustment for 

possible bias due to statistical autocorrelation. The adjusted variance then better reflects the 

underlying variability that would be present if the data were collected over a longer period. 

When data are said to be positively autocorrelated, it means that measurements taken at specific 

time intervals (such as 1 day or 2 days apart) are related. For example, positive autocorrelation 

would be present in the data if the final effluent concentration was relatively high one day and 

was likely to remain at similar high values the next and possibly succeeding days. 

The autocorrelation used for the calculation of the limitations is based on the maximum 

likelihood estimate of the serial correlation when fitting an autoregressive lag-1 (AR(1)) model 

to the data. This procedure accounts for the timing of the sample collection. EPA’s methodology 

for autocorrelation is appropriate whether or not the samples are collected on sequential days and

regardless of the sign of the correlation (positive/negative). EPA does not assume or require that 

the samples are collected at the facilities be sequential daily samples.

Appendix B of the TDD describes in detail the equations used to calculate the limitations in the 

final rule and how the autocorrelation is used in those calculations. The autocorrelation is used in 

two places, first to adjust the standard deviation of the observed effluent concentrations to 

estimate the standard deviation of the long-term effluent concentration series (see equations (17) 

to (19)), and second to calculate the standard deviation of the monthly average (see equations 

(34) and (35)). The first calculation depends on the sequence of sample collection dates. The 

second depends on the assumed monitoring frequency used to calculate the monthly average 

limitation. The equations for this final rule were previously used for the Iron and Steel effluent 

guidelines except those guidelines used equation (19) instead of equation (18). Because the 

samples for this rule were not collected on sequential days, equation (18) is used. In equation 

(18) in Appendix B of the TDD for the final rule, EPA calculates the ratio of the variance of the 

sample of N correlated observations to the variance of the long-term time series. The calculation 

accounts for the spacing of the sample collection dates. Based on the cited source, the equation 

given in the comment is the ratio of the variance of the mean (as opposed to the data) of N 

correlated sequential observations to the variance of the mean of N independent observations. 

EPA acknowledges that, in its calculations for the proposed limitations, 1) there was a 

programming error affecting the calculated correlation which affected the correlation for 

selenium in particular; and 2) the calculations for the proposed rule had the unexpected result 

that some limitations decreases when the assumed correlation was increased from zero. EPA 

corrected the programming error for calculating the autocorrelations for the final rule. In 

response to comments, EPA reviewed how the autocorrelation adjustment was handled in the 

proposed rule and in previous effluent guidelines. As a result of that review, EPA revised the 

equations used to calculate the effluent limitations for the final rule. Using the revised equations, 

the autocorrelation adjustment is applied to the continuous portion of the modified deltalognormal distribution without treating all observations as detected. Using the resulting 

equations, the autocorrelation-adjusted variance always increases as the autocorrelation 

increases. Given these changes, EPA does not agree that any other changes need to be made to 

the calculation procedures. 

4.1.2. Precision and Bias

Comments express concern with precision and bias associated with the statistical approach. 

Precision refers to the variability, or stability, of an estimate. Bias refers to the accuracy of an 

estimate. Regardless of the statistical model EPA uses, parameters will necessarily be more 

precisely estimated when the sample sizes used in the statistical analysis are large. Sample size 

enters into the standard error calculation of estimates (s.e.; where s.e. is the standard deviation of 

an estimate) in the denominator; thus larger sample sizes result in decreased variability of 

parameter estimates. In theory, the primary determinant of whether a precision constraint is 

satisfied is sample size. The greater the sample size, the greater the precision (i.e., the smaller the 

standard deviation) of an estimated parameter will be.

Bias, or accuracy, is the difference between the estimated value of a given parameter and the true 

value of said parameter. Several parameters are used in calculating the limitations; mean and

standard deviation of the log-transformed concentrations, long-term average (LTA), daily 

variability factor (VF1), standard deviation of the untransformed measurements, 99th percentile 

of the distribution of daily concentrations, and 95th percentile of the distribution of the monthly 

average concentrations. Comments (e.g., DCN EPA-HQ-OW-2009-0819-4499-A1, Comment 

Excerpt #15 (in Comment Code 31) spuriously assert that “Use of small data sets leads to 

underestimation of standard deviation, and hence, underestimation of regulatory limits.”

Admittedly, large samples are preferred to small samples; however, the comment only raises half 

of the issue by emphasizing an under-estimation of a parameter. A parameter estimate from a 

small sample may be just as likely to overestimate a parameter. The comment’s emphasis on 

under-estimation is unwarranted.

Additionally, eliminating biased parameter estimation globally is difficult, if not impossible in 

most cases, given the number of parameters that are being estimated. Some parameters may be 

biased while others are not. A parameter that is unbiased in a linear scale (original measure) may 

become biased when transformed into a log scale (transformed measure); and vice versa. For 

example, for lognormally distributed data, the variance of the log-transformed concentrations is 

mean unbiased but the standard deviation and daily variability factors calculated from the 

variance are biased. The mean of the log-transformed concentrations is both mean and median 

unbiased. If the variance of the log-transformed concentrations is scaled to be median unbiased, 

then the LTA and standard deviation of the untransformed concentrations will not be median 

unbiased. As a result, there is no approach that will make all parameters unbiased, based on 

either the expected mean or median. Thus, the selection of the estimation methods involves 

judgment as to which biases should be minimized. 

If the data have a lognormal distribution, the estimates of the LTA, VF1, standard deviation of 

the concentrations, 99th percentiles of the daily values and 95th percentile of the monthly 

averages are all positively skewed. EPA is particularly concerned about high values and is thus 

more interested in estimates that are relatively unbiased based on the mean (which is more 

sensitive to the high values than the median). Some comments suggest that the standard 

deviation of the untransformed measurements (estimated from the mean and standard deviation 

of the log-transformed measurements) should be adjusted to be median unbiased (i.e., the 

estimates are just as likely to be lower than the true value as higher than the true value). A 

particular comment provides a possible algorithm for adjusting the standard deviation to be 

median unbiased but does not address the bias associated with other parameters. The comment 

provides no justification for why median unbiased-ness should be preferred to mean unbiasedness or why the bias of the standard deviation is more important than other parameters. Given 

that the equations used by EPA are based upon standard methodology, EPA considers the 

equations as implemented to result in a reasonable compromise between median and mean 

unbiased estimates for the parameters used to calculate the limitations.

4.1.3. Engineering Analyses Used to Evaluate the Model

EPA is concerned that the presentation of the engineering analyses presented at proposal may 

have been misconstrued in comments that assert or imply that EPA expects occasional 

exceedances of the limitations. This conclusion is incorrect as EPA has established that facilities 

are capable of complying with the limitations at all times by properly operating and maintaining 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-20

their processes and treatment systems. As explained in Essay Section 2.2, the statistical 

methodology is used as a framework to establish the limitations based on percentiles. Statistical 

methods provide a logical and consistent framework for analyzing a set of effluent data and 

determining values from the data that form a reasonable basis for effluent limitations. The 

limitations were never intended to have the rigid probabilistic interpretation that has been 

adopted in comments on this and other rulemakings. That is, merely because probability models 

are used to develop limitations, facilities are not expected to operate processes and treatment 

systems so as to violate the limitations at some pre-set rate. Rather, facilities are expected to 

design and operate processes and treatment systems in a manner (the long term average) that will 

result in compliance with limitations.

The statistical analysis used to develop the monthly average limitations uses daily measurements 

taken weekly over a month. To evaluate the achievability of the limits, EPA conducts a second 

review of the limits once calculated. To do this, EPA first compared the daily effluent values to 

the daily limits to identify any values above the daily limit. EPA then compared the effluent data

to the monthly average limits, for those periods where there are sufficient data to represent 

weekly monitoring over a month, and identified those months where the average of all daily 

values for the month is above the monthly limit.

After thoroughly evaluating the results of the comparison between the limits and the effluent 

values used to calculate the limits (see details below), EPA determined that the statistical 

distributional assumptions used to develop the limits are appropriate for the data (that is, they 

provide a reasonable “fit” to the actual effluent data) and the limits for each wastestream are 

reasonable and achievable. If a plant properly designs and operates its wastewater treatment 

system to achieve the long-term average for the model technology (rather than targeting 

performance at the effluent limits themselves), it will be able to comply with the limits. In 

comparing the effluent data to the limits, EPA noted there are instances where one or more daily 

values in a month are higher than the monthly limit, but the average of all results in a month are 

equal to or less than the monthly average limit. Instances such as these are normal and consistent 

with the way effluent limits are calculated and implemented in NPDES permits. (See the 

statistical support document for more information.)

Based on the comparisons of effluent and influent data to the limits, and information described 

elsewhere in the record for the ELGs, EPA determined that the statistical distributional 

assumptions are appropriate for the effluent data and that the daily maximum and monthly 

average limits for the rule are reasonable and achievable.

Industry argues that to calculate the monthly average limitation, EPA should have taken all data, 

even where there was only one sample to represent the performance of the whole month. EPA 

disagrees because doing so would not correspond to the monitoring frequency and one data 

sample in a month would not be representative of what the facility achieves over a month where 

weekly samples are taken. EPA’s approach is consistent with the manner in which EPA 

calculated the limits and by which plants will monitor for compliance with NPDES permits. It is 

also consistent with the monitoring frequency EPA has generally observed in NPDES permits, 

for those pollutants for which the permit includes effluent limits. Additionally, it is consistent 

with EPA’s methodology for estimating compliance costs for the final rule, which includes 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-21

estimated O&M costs for weekly compliance monitoring. Most importantly, EPA’s approach is a 

reasonable approach for conducting the engineering review because an assessment that uses data

from less frequent monitoring may more closely reflect the daily variability than the monthly 

variability and therefore would not accurately reflect whether the monthly limit would have been 

met. EPA identified some cases where only one sample was taken during a month and the 

resulting concentration value for that one sample is above the monthly limit. In such cases, 

additional monitoring of the effluent (e.g., at weekly intervals) would likely result in a monthly 

average that would fall below the monthly average limit. For example, comparing with the 

limits calculated for arsenic, the 4 weekly samples collected from Hatfield’s Ferry in February 

2010 are all equal to or below the daily limit of 11 μg/L. One of these observations (11 μg/L) is 

higher than the monthly limit of 8 μg/L. However the average of all daily values for the month is 

7.5 μg/L, which is below the monthly limit.

4.1.4. Cross-Validation (e.g., Jackknife)

Comments suggest that EPA use cross-validation methods such as jackknife procedures (e.g., 

Excerpt 122 in EPA-HQ-OW-2009-0819-4499-A1) in evaluating the limitations. EPA disagrees 

that cross-validation procedures are necessary in evaluating the limitations and the statistical 

model. Using the jackknife method to estimate or forecast a frequency of limit exceedance is 

inappropriate. EPA’s position here is similar to the position described in the sections concerning 

statistical methodology (2.2) and the 99th and 95th percentile selection (2.3); these limits are not 

meant to be interpreted in a rigid probabilistic fashion (i.e. that a pre-set proportion of violations 

are expected). Part of EPA’s intent in setting the prescribed limits is to encourage facilities to 

target long term average discharges rather than focusing on operating just under the prescribed 

limits. EPA used only data from actual effluents from well operated facilities using the 

technology-basis for the BAT ad BADCT limitations. 

 

4.2 Alternative Statistical Approaches

While EPA has found that the modified delta-lognormal model is appropriate to apply to effluent 

data for many industrial categories, EPA also recognizes that there are alternative statistical 

techniques that could be used to model data that contain both detected and non-detected 

measurements. Furthermore, in certain situations, the modified delta-lognormal approach may be 

improved relative to yielding more accurate estimates of distributional parameters. This section 

addresses comments that asserted that other statistical approaches are more appropriate for the 

steam electric data. The following sections describe EPA’s consideration of each and reasons for 

rejection.

4.2.1. Tolerance Limits

Comments have advocated what is known as ‘confidence,’ ‘UCL95,’ or ‘tolerance limits.’ A 

tolerance limit (or β-content tolerance limit) is not a point estimator but rather an interval 

estimator having the property of being larger than the desired quantity with a stated degree of 

statistical confidence. The 95 or 99 percent upper tolerance limit estimator recommended by 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-22

comments will always, by design, be larger than the point estimator used by EPA. Interval 

tolerance limits are based on accepted statistical methods. They are, however, designed for 

special applications in which it is critically important to obtain an upper bound on a quantity and 

in which the cost of substantially overestimating that quantity is small. EPA has determined that 

this type of effluent limitation would be inappropriate and would allow discharges that would 

greatly exceed the observed performance of the model technologies for the steam electric 

industry. In fact, use of upper tolerance limit as the basis for effluent limitations has been 

proposed by commenters on other rulemakings. These proposals have been rejected by EPA. As 

a matter of standard practice, EPA has determined that the 99th percentile of the distribution of 

daily measurements is an appropriate basis for daily maximum limitations. This policy of using 

the 99th percentile as a basis has been adhered to in developing daily maximum limitations and 

standards in effluent guidelines rulemakings for nearly 30 years. In 1976, the Court in API, 

supra, 540 F.2d 1023, 1035-36 (10th Cir. 1976) described the daily variability factor correctly as 

the “‘99th percentile probability of occurrence divided by the mean.’ The result is ‘the multiplier 

by which the long-term achievable values must be multiplied in order to derive the value not 

permitted to be exceeded.’” The definition and use of the daily variability factor is the same in

this rule. The API Court then rejected the refineries’ argument: “Because EPA selected the 99th 

percentile, the refineries say that they must be afforded at least four days a year, 1% of 365, 

when they make excess discharges without fear of penalty. The reasoning does not impress us.” 

EPA considers facilities that are properly operated and controlled are capable of complying with 

the promulgated limitations and standards. Thus, EPA has determined that tolerance limits 

proposed by the comment are inappropriate. A confidence or tolerance limit would provide an 

upward adjustment in the percentile value, and thus, EPA has determined that this type of 

effluent limitation would be inappropriate and would allow discharges that would greatly exceed 

the observed performance of the model technologies. Also see Pratt & Gibbons7for a discussion 

of the disadvantages of using and interpreting tolerance limits.

4.2.2. Other Censored Approaches (e.g., Survival Analysis)

Censored likelihood-based approaches treat non-detected observations as unobserved 

concentrations below detection limits but with the same concentration distribution as detects. 

The statistical distributions are fit to the data by maximum likelihood instead of the exact 

numerical calculations that are possible using the modified delta-lognormal distribution.

Comments suggested that EPA use survival analysis, often citing the Kaplan-Meier (KM) 

approach, for use in developing the limitations. KM is a standard approach used for years by the 

medical sciences to handle censored data that yields a nonparametric maximum likelihood 

estimate of the cumulative distribution function (CDF) (e.g., Lawless, 2003) that is conditioned 

on the sample having concentration above the smallest detection limit. While most statistical 

software packages implement the KM algorithm for right-censored survival data, it can be 

applied to left-censored environmental data by using a “flipping” transformation that results in

left-censored samples becoming right-censored. It is equivalent to fitting a (known membership) 

mixture of an empirical distribution for detects and a truncated empirical distribution for nondetects (truncated at their respective detection limits). It yields an empirically-generated

10-23

cumulative distribution function (CDF). If all detects are above detection limits, this approach is 

equivalent to simple substitution where non-detected results are replaced by their respective 

detection limits. It estimates the CDF conditioned on the sample being detected. Thus, estimates 

are biased if the proportion of non-detects below the smallest detection limit is significant.

For most of the data sets with censored values, the Kaplan-Meier method does not provide an 

estimate of the standard deviation of the data (because the smallest observation is censored) 

unless a substitute value is used for the smallest non-detect value, which in some cases means a 

substitute value for all non-detects. Maximum likelihood methods for censored data can be used 

with a second step to adjust for non-detects or baseline concentrations. As noted in the response 

to excerpt 127 in EPA-HQ-OW-2009-0819-4499-A1, for the purposes of calculating the 

limitations, EPA is interested in the characteristics of the distribution in which the non-detects 

have been replaced by the detection limit. In this context, the Kaplan Maier standard deviation 

and maximum likelihood methods provide no advantage over the EPA calculations using the 

modified delta-lognormal distribution. 

When considering not just KM, but survival analyses techniques in more general way, EPA notes 

that the outputs from survival analyses require a subsequent adjustment to account for the effects 

of the baseline adjustment. Thus, the modified delta-lognormal equations provide a more direct 

method for calculating the limitations. In conclusion, EPA has no evidence and the comments 

have provided no evidence that survival analysis should be preferred to using the modified deltalognormal distribution.

Comments asserted that EPA had not considered other approaches. In addition to survey analysis 

approaches, EPA also considered two other approaches to handling censored data: 1) the 

censored lognormal distribution; and 2) regression on order statistics (ROS).

Censored likelihood-based approaches can be modeled using a common parametric 

concentration distribution (lognormal) for both detects and non-detects. Non-detected values are 

treated as censored lognormal observations. Because the censoring point is a detection limit for 

the lab analysis, no detected measurements can fall below their respective detection limits. 

Parameter estimates may be unstable if large gaps appear between detection limits and detected 

measurements. Its sensitivity to the lognormal distribution assumption implies that the censored 

lognormal approach should be accompanied by a rigorous evaluation of diagnostics for verifying 

adherence of the concentration values to the lognormal distribution. 

ROS techniques were investigated relative to their application to data sets with multiple 

detection limits. While ROS can be implemented in a parametric setting, a more robust form of 

ROS is more frequently recommended for use and, therefore, was considered in this evaluation. 

Robust ROS involves the imputation of concentration values for non-detects according to the 

outcome of a linear regression fit of detected (transformed) concentration values to normal 

scores (i.e., percentiles of the normal distribution). Thus, unlike the modified delta-lognormal 

approach, ROS assumes that:

 All reported concentrations (i.e., both detects and non-detects) follow a common 

distribution.
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-24

 Each non-detect is treated as an unobserved left-censored value from this distribution, 

known only to be less than the sample’s detection limit.

In Robust ROS, a non-parametric, empirical estimate of the concentration distribution is 

estimated with data from both detects and non-detects using an algorithm described in Helsel and 

Cohn (1998). The distribution is used to estimate the empirical percentile at each measured 

concentrations (in detects). 

EPA has not selected the censored lognormal distribution or Robust ROS because of the 

imputation for non-detected values which would not be consistent with reporting requirements 

for compliance with limitations.

4.2.3. Use of Methods for Randomness

EPA disagrees with comment assertions such as “The pattern of sampling of effluent samples 

resembles two-stage sampling with the primary sampling unit being month and the secondary 

sampling unit being day” (e.g., comment EPA-HQ-OW-2009-0819-4655-A18). Two stage 

sampling is a complex survey design, defined by Hansen et al (1953, page 239) as: 

...a design in which:

(a) Two-stage sampling is used:

(b) The primary units are selected by simple random sampling;

(c) The second-stage units are selected from each of the selected primary units by 

simple random sampling; and

(d) The second-stage sampling fractions are uniform for all selected primary 

sampling units.

The commenters did not provide any evidence that facilities had used statistical two-stage survey 

designs to choose months at random and then days at random within the months. Facilities 

typically collect samples when it is convenient for the operating staff, not by some 

predetermined randomly generated selection of months and days. Thus, the selection of sample 

collection dates was not based on two-stage sampling, and thus, the procedures for two-stage 

sampling are wholly inappropriate for use in limit calculations. EPA does not agree that survey 

statistical procedures for two-stage sampling should be used to estimate the variance of the 

effluent data because the commenter’s approach would only be appropriate for data collected 

using a two-stage survey design, which EPA did not use in collecting the effluent data, nor did 

comments or facilities provide any evidence that facilities used a two-stage sampling design to 

randomly select sampling days. Instead of using a survey design which would have reduced the 

amount of data, the Agency used the data it had in the record that met the data acceptance 

criteria..

Comments also suggested that the sampling days could be assumed to have been selected by a 

simple random sample (SRS). Hansen et al (1953, page 12) defines a simple random sample as:

...a sample selected from a population in such a manner that each combination of n

elements has the same chance or probability of being selected as every other 

combination. Whenever the method of selecting the sample is such that each combination 

of n elements does not have the same chance of being selected, the method of selection is 

not simple random sampling. 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-25

The commenters did not provide any evidence that suggested that a SRS approach was used to 

statistically select days on which to collect effluent samples. Thus, it would be inappropriate to 

apply SRS techniques in calculating the limitations. 

Comments may have confused EPA’s statistical design for collecting the data through its 

establishment surveys with its collection of effluent data. The survey data were collected by a 

two-stage sampling design, but the effluent data were not and consist of all valid data made 

available to EPA. From the self-monitoring and the EPA sampling data, EPA then used data that 

represented the model technologies. Because the effluent data were not randomly selected, it 

would be inappropriate to apply survey statistical approaches to the data in calculating effluent 

limitations.

5. Compliance with Permit Limitations

Comments expressed concerns about complying with the limitations. The following two sections 

provide additional clarification about EPA’s policy in complying with limitations using nondetected measurements and more generally in complying with all limitations.

5.1 Non-Detected Measurements

Permit authorities are responsible for providing any necessary guidance in using non-detected 

measurements for compliance monitoring. Because EPA has developed limitations using two 

approaches to baseline value substitutions for the non-detected values (see Essay Section 3.5) 

and otherwise used the largest possible value (i.e., the full value of the sample-specific detection 

limit), EPA concludes that any reasonable substitution method can be used in reporting daily 

measurements below detection and to calculate averages for compliance monitoring. 

5.2 Compliance Required Except During Upset or Bypass

In the final record (see DCN SE05733), EPA provides summaries of the engineering review of 

the effluent limits. In these analyses, the limitations based on percentiles are compared to the 

data used to develop the limitations to determine if EPA used appropriate distributional 

assumptions for the data used to develop the limitations, in other words, whether the model EPA 

used provides a reasonable “fit” to the actual effluent data.

The 95th and 99th percentiles do not relate to, or specify, the percentage of time a discharger 

operating the “best available” or “best available demonstrated” level of technology will meet (or 

not meet) the limitations and standards as suggested by the comments. Rather, the use of these 

percentiles relate to the development of limitations. (The percentiles used as a basis for the 

limitations are calculated using the products of the long-term averages and the variability 

factors.) If a facility is designed and operated to achieve the long-term average on a consistent 

basis and the facility maintains adequate control of its processes and treatment systems, the 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-26

allowance for variability provided in the limitations is sufficient to meet the requirements of the 

rule. As stated elsewhere in this response, the use of the 99th and the 95th percentiles represents a 

need to draw a line at a definite point in the statistical distributions (the 100th percentile would 

not work because it would represent infinity) and a policy judgment about where the line that is 

drawn would ensure that operators work hard to ensure practices that represent the appropriate 

level of control. In essence, in developing the limitations established in this rule, EPA has taken 

into account the reasonable anticipated variability in discharges that may occur at a welloperated, maintained, and designed facility. This conclusion also applies to the arsenic 

limitations for which all of the data that EPA used to set the limitation were non-detected. 

The issue of exceedances or excursions raised by the comments is not unique to the steam 

electric rule. (For example, several comments suggest that EPA include a provision that a facility 

is in compliance with permit limitations if its discharge does not exceed the specified limitations, 

except that the discharge may exceed the monthly average limitations one month out of 20 and 

the daily average limitations one day out of 100.) This issue has, in fact, been raised by other 

comments in other rules, most notably in EPA’s final Organic Chemicals, Plastics, and Synthetic 

Fibers (OCPSF) rulemaking. EPA’s general approach there, which is the same in this rule for the 

limitations based on percentiles, was upheld in Chemical Manufacturers Association v. U.S. 

Environmental Protection Agency, 870 F.2d 177, 230 (5th Cir. 1989). The Court determined 

that:

EPA reasonably concluded that the data points exceeding the 99th and 95th 

percentiles represent either quality-control problems or upsets because there can 

be no other explanation for these isolated and extremely high discharges. If these 

data points result from quality-control problems, the exceedances they represent 

are within the control of the plant. If, however, the data points represent 

exceedances beyond the control of the industry, the upset defense is available.

More recently, for EPA’s rule for the iron and steel industry, EPA’s selection of percentiles was 

upheld in American Coke and Coal Chemicals Institute v. Environmental Protection Agency, 452 

F.3d 930, 945 (D.C. Cir. 2006). The Court determined that:

The court will not second-guess EPA’s expertise with regard to what the maximum 

effluent limits represent. See Nat’l Wildlife, 286 F.3d at 571-73. As EPA explains in the 

Final Development Document, the daily and monthly average effluent limitations are not 

promulgated with the expectation that a plant will operate with an eye toward barely 

achieving the limitations. Final Development Document at § 14.6.2. Should a plant do so,

it could be expected to exceed these limits frequently because of the foreseeable variation 

in treatment effectiveness. Rather, the effluent limitations are promulgated with the 

expectation that plants will be operated with an eye towards achieving the equivalent of 

the LTA for the BAT-1 model technology. Id. However, even operated with the goal of 

achieving the BAT-1 LTA, a plant’s actual results will vary. EPA’s maximum daily

limitations are designed to be forgiving enough to cover the operations of a well-operated 

model facility 99% of the time, while its maximum monthly average limitations are 

designed to be forgiving enough to accommodate the operations of a well-operated model 

facility 95% of the time. See id. EPA’s choice of percentile distribution represented by its 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-27

maximum effluent limitation under the CWA represents an expert policy judgment that is 

not arbitrary or capricious.

EPA has decided that the statistical methodology provides a reasonable framework for 

establishing limitations based on percentiles that are achievable by facilities with well operated 

and controlled processes and treatment systems. EPA also has decided that the arsenic limitations 

described in Section 2.5 include allowance for reasonable anticipated variability. Thus, EPA 

considers daily values above the daily maximum limitations and monthly averages above the 

monthly average limitations will be due to either upset conditions or deficiencies in process and 

treatment system maintenance and operation. If the exceedance is caused by an upset condition, 

the facility would have an affirmative defense to an enforcement action if the requirements of 40 

CFR 122.41(n) are met. If the exceedance is caused by a design or operational deficiency, then 

the facility’s performance does not represent the appropriate level of control (best available 

technology for existing sources; best available demonstrated technology for new sources). Such 

exceedances can be controlled by diligent process and wastewater treatment system practices 

(e.g. frequent inspection and repair of equipment, use of back-up systems, close attention to 

treatment system operating parameters and effluent quality, communication and coordination 

among production and wastewater treatment personnel). In the treatment system, wastewater 

equalization tanks also contribute to making influent raw wastewater flow and quality more 

uniform. EPA has determined that use of these techniques, as well as others, will result in 

discharge levels that do not exceed the limitations.

EPA’s allowance for reasonable anticipated variability in its effluent limitations, coupled with 

the availability of the upset defense reasonably accommodates acceptable excursions. Any 

further excursion allowances would go beyond the reasonable accommodation of variability and 

would jeopardize the effective control of pollutant discharges on a consistent basis and/or bog 

down administrative and enforcement proceedings in detailed fact finding exercises, contrary to 

Congressional intent. See, e.g., Rep. No. 92-414, 92nd Congress, 2nd Sess. 64, reprinted in A 

Legislative History of the Water Pollution Control Act Amendments of 1972 at 1482; Legislative 

History of the Clean Water Act of 1977 at 464-65.

The majority of circuit courts considering the excursion issue have concluded that EPA is not 

required by law to include any excursion provision in its regulations or permits and have set forth 

a variety of reasons why such a provision would in fact be inconsistent with statutory policy 

goals. A brief review of these cases is instructive.

In American Petroleum Institute v. EPA, supra, various petroleum refineries urged that 

“excursions” be allowed. 540 F.2d at 1036. They argued that because EPA used a 99th percentile 

approach to derive the effluent limitations, they must be allowed at least four days a year (one 

percent of 365 days) to make excess discharges without fear of penalty. The Tenth Circuit 

rejected this argument, stating that “the temptation to store pollutants for future discharge would 

be enticing.” Id. At 1036. The court also noted that the limits already allowed for considerable 

variability and that variations should lessen as technology improves.

In CPC International v. Train, supra, petitioners similarly argued that EPA’s 99th percentile 

analysis for the effluent guideline there in issue accounted for only 99 percent of the predictable 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-28

variability and that EPA should allow effluent levels to exceed the limits several days a year. The 

Eighth Circuit rejected this argument, accepting EPA’s statement that plants could reduce their 

variability through the use of better treatment technology and control, attention to treatment plant 

maintenance and operations, and concern about in-plant waste control. While this case dealt with 

new plants, the Eighth Circuit subsequently reaffirmed its conclusion with respect to existing 

facilities as well. Corn Refiners Association, Inc. v. Costle, supra. The Court specifically 

acknowledged that “there is substantial force to petitioner’s argument that EPA’s regulations 

seemingly require petitioners to do the impossible, i.e., to prevent excursions which, by their 

very nature, can occur even in a properly operated facility meeting BPCTCA standards.” 594 

F.2d at 1223. However, the court stated that against this potential hardship “we must weigh the 

effect which a decision requiring excursion provisions in the regulations or individual permits 

would have on the important policies underlying the Act.” Id.

First, the Court noted that a decision requiring an excursion provision might hamper EPA’s 

ability to compel plants to improve their antipollution performance. Denying excursion 

provisions justifiably compels the industry to develop the technological capability necessary to 

avoid excessive discharges. Accord, United Steel Corp. v. Train, supra, 556 F.2d at 842

one of the goals of the NPDES permit program is to insure that pollution control facilities 

are operated as efficiently and carefully as possible). Second, an excursion provision could 

prevent the “swift and direct” enforcement contemplated by Congress, subjecting 

enforcement proceedings to murky determinations concerning the sequence of events in the 

plant, whether those events would have been avoidable if other equipment had been 

installed, and whether the discharge was within the intent of the excursion provision. 

Consequently, what Congress planned as a simple proceeding suitable for summary 

judgements would become a form of inquest into the nature of system malfunctions. 594 

F.2d at 1126 (quoting from Weyerhaeuser, supra, 590 F.2d at 1058).

In Weyerhaeuser Co. v. Costle, supra, all of the above grounds were relied upon to reject the 

petitioner’s arguments. The court then concluded:

We believe it appropriate to defer when EPA, in the interest of preserving an 

enforcement system based on straightforward numbers, establishes a general rule 

with better than 99 percent accuracy and leaves the rest to prosecutorial 

discretion.

590 F.2d at 1058.

A general provision excusing excursions that are “statistically foreseeable” would have precisely 

the disastrous effect on the policies underlying the Act that so concerned the Courts in 

Weyerhaueser and Corn Refiners. Contrary to the legislative intent, such an approach would 

introduce into every enforcement action the need to adjudicate the foreseeability of each and 

every permit violation. This suggestion is fraught with the potential to wreak havoc with the 

swift and effective enforcement contemplated by Congress.

In support of their suggestion that EPA allow periodic exceedances (or excursions) to all 

limitations (one day out of 100 for daily averages and one month out of 20 for monthly averages) 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-29

in this rule, commenters refer to provisions which allow periodic exceedances in the pH effluent 

limitations (40 CFR § 401.17) and in standards for particulate matter for fossil-fuel-fired boilers 

(40 CFR § 60.42(a)(2)). Particulate matter is an air, rather than water, regulation and therefore 

does not represent the best available technology or best available demonstrated control 

technology as those terms are used in the Clean Water Act. The pH regulation (40 CFR § 

401.17) similarly does not represent BAT or BADCT, and only applies for one conventional 

parameter, pH, when continuously monitored. 40 CFR part 136, which lists the approved EPA 

analytical methods, states that pH may be analyzed both continuously and by grab sample. 40 

CFR § 401.17 does not apply in instances where pH is not continuously monitored. The 

excursions allowed in the pH and particulate matter regulations are not analogous to the steam 

electric effluent limitations because this rule does not provide for continuous monitoring. 

Only two cases have held that excursions must be accommodated in any fashion, and both of 

these decisions are satisfied by EPA’s upset and bypass regulations. Marathon Oil v. EPA, supra; 

FMC Corp. v. Train, supra.

8 The Court in FMC did not in any way specify the parameters of 

such an excursion provision. The court in Marathon Oil required EPA to insert an “upset 

provision” into permits and stated that EPA may place the burden of proof on the permit holder. 

EPA’s promulgation of § 122.41(n) satisfies the court’s decision. See American Petroleum 

Institute v. EPA, 661 F.2d 340, 350-53 (5th Cir. 1981).

The upset provision promulgated by EPA is narrowly drawn to address only those temporary 

excursions which are demonstrably excusable. Equally important, the upset provision places on 

the permittee the affirmative duty to identify and justify the upset when it occurs. Any broader 

excursion provision is likely to simply allow dischargers to avoid treating excursions with the 

degree of prompt and serious attention required by the upset regulation.

It must be remembered that the purpose of permit limits is not to validate dischargers’ current 

practices but rather to require dischargers to act in a manner that assures that their discharges are 

controlled at the BAT or BADCT level of control. If exceedances are regarded, not as violations 

to be regarded seriously by dischargers and enforcement authorities, but rather as “expected” and 

unworthy of serious attention, discharges will inevitably increase beyond the levels that can be 

achieved through vigilant control. It is for this reason that EPA Administrators to date have 

uniformly chosen to address allegedly unavoidable exceedances only through the exercise of 

enforcement discretion, and courts have uniformly upheld this administrative approach, provided 

that a mechanism was made available to address genuine upsets.

While EPA’s statistical methodology and the upset defense combine to accommodate 

dischargers’ variability to the extent required by law, as interpreted unanimously by the circuit 

courts; dischargers are protected even further by EPA’s traditional exercise of enforcement 

 

8 The court in FMC cited as precedent EPA’s use of excursions in defining national 

ambient air standards (NAAQS), under the Clean Air Act, in 40 CFR Part 50. However, those 

standards are descriptions of air quality rather than control standards directed at particular 

facilities. EPA’s control standards for facilities emitting air pollutants, such as new source 

performance standards and national emission standards for hazardous air pollutants under 

sections 111 and 112 of the Clean Air Act, 42 U.S.C. §§ 7411 and 7412, do not contain 

excursion provisions.

discretion. CPC International v. Train, supra, 540 F.2d at 1337; Weyerhaeuser Co. v. Costle, 

supra, 590 F.2d at 1058. Cf., General Motors Corp. v. EPA, 738 F.2d 97, 101 (3rd Cir. 1984) 

(where only isolated examples of noncompliance are anticipated, a later particularized appeal to 

enforcement discretion is more appropriate than a general rulemaking to modify the underlying 

requirement). None of the comments argue that EPA has exercised its discretion unreasonably in

the past or that EPA is likely to do so in the future. 

EPA includes an upset provision in NPDES permits; this EPA has done in its NPDES regulations 

at 40 CFR 122.44(n) for exceptional situations where there is unintentional and temporarily 

noncompliance due to factors beyond the reasonable control of the permittee. FMC Corporation 

v. Train, 539 F.2d 973 (1976) upheld EPA’s use of variability factors (the Court, in FMC, said 

that the purpose of variability factors was to account for routine fluctuations; they are not 

intended to allow for poor performance), and is distinguishable with respect to excursions 

because in FMC, unlike this rule or OCPSF, it was established that “even a proper treatment 

facility will be in violation on a few occasions.” See FMC, 539 F.2d at 986. Here, as in OCPSF, 

a well operated plant will be capable of meeting the limitations and standards. The Fifth Circuit 

in CMA v. EPA, supra, 870 F.2d at 830 held that EPA “reasonably concluded that data points 

exceeding the 99th and 95th percentiles represent either quality control problems or upsets 

because there can be no other explanation for these isolated and extremely high discharges.”

EPA has determined that the limitations allow for sufficient variability so that the limitations are

achievable by proper operation of the technologies. EPA considers well-operated facilities 

capable of complying with the limitations at all times, as stated above and in the record for the 

rule. Furthermore, in developing limitations, EPA provides an allowance for variability in the 

effluent. If the plant maintains adequate control of its processes and treatment systems, the 

allowance for variability provided in the limitations should be sufficient.

I would like to target my comments today to address risk assumptions posed in the text of the 

Proposed Rule in the reading of Section III, Background, G, and I'm sure you're familiar with 

that section. It talks about the information collection request conducted by EPA's Office of 

Water for the ELG rule that has the potential to affect the risk assessment for the CCR 

rule: "...reliance on the data and analyses discussed...may have the potential to lower the CCR 

rule risk assessment results by as much as an order of magnitude...and could support regulation 

of CCR disposal under RCRA Subtitle D...."

I would like to take the time allotted today to share an example from Missouri, actually from my 

town, that supports the conclusion that more independently collected site specific data is needed 

to draw conclusions about numbers of human receptors impacted and assumptions made about 

water flow in our nation's floodplains and near ash way sites because much like the communities 

that are impacted, all these sites are in our floodplains.

Comment Excerpt: 

The Labadie power plant was constructed in 1970 when I was 9 years old with one large 150 

acre unlined ash pit dug into the floodplain sitting in our groundwater. The pond and the 79 acre 

pond constructed in 1993 together have been discharging untreated coal and plant wastewater 

into the Missouri River at volumes of 30 million gallons per day under NPDES permits. The 

four identified leaks, two of which date at least back to the permit issued in '92, have contributed 

at least 383 million gallons of untreated wastewater into the floodplain with no groundwater 

monitoring.

I would like to submit into the record, which unfortunately I left at the hotel, but I will do that 

digitally, a map that is of the floodplain and the domestic wells located within a 3 mile radius of 

the existing ponds in the proposed landfill that would accept increasingly toxic coal ash waste for 

the next 40 years. The well data was plotted by Washington University's Interdisciplinary 

Environmental Clinic for LEO, which is our organization, as part of legal action to attempt to 

stop the siting of the landfill in the floodway, not just floodplain, but the floodway of our 

floodplain.

I am also providing a landfill drawing included in the permit document submitted by the utility to 

the Missouri Department of Natural Resources, which chose the same private wells and three 

springs in the floodplain. LEO contracted the services of hydrogeologist Charles Norris to 

review the piezometer data from the Ameren's detailed site investigation, and he and others 

indicated that water flow was relatively unpredictable, with water moving seasonally either 

toward the river or toward drinking wells south of the site.

What was amazing was the short time frame in which water could change directions and likely 

move toxins long distances. The subsequent review of the proposed groundwater monitoring 

program at the proposed landfill did not reflect the hydrological complexities.

Unfortunately, I suspect the facts and decisions made in the Labadie case are not an exception 

but the norm. The facts suggest that we should look closer before permitting said sites, and 

regulations absolutely need to be more protective.

In conclusion, LEO and CCC recommend that EPA not rely on limited industry supplied data on 

hydrogeology at these sites to weaken a strong subtitle C coal ash rule, coupled with a very 

strong ELG rule, to finally protect communities impacted by coal ash waste and wastewater risk.

In the proposed ELG rules in the Federal Register, EPA stated that we have new data from a 

2010 information collection request, and that that data could be used to determine the extent to 

which plumes of groundwater contamination leaching from these coal ash disposal sites might be 

intercepted by surface water bodies.

And the narrative goes on to suggest that a risk assessment incorporating that information might 

reduce the risk assessment by as much as an order of magnitude, and we are really concerned 

about EPA's reliance on this one sided data set that was provided by the utility industry. We 

think that too much reliance on that data could lead to adoption of rules that fail to protect human 

health and the environment.

Further, the industry documents generally assume that groundwater in these alluvial aquifers is 

moving in the same direction as the adjacent river, when in fact if you look at a more detailed 

level, there is often documentation that groundwater can flow in the opposite direction, 

especially if there are significant water withdrawals in the vicinity that could change the 

groundwater flow. And an example of that is the Gibson Power Plant where there is 

documentation of groundwater contamination in wells that are upriver from the plant.

Comment Excerpt: 

On behalf of the State of Kansas, I appreciate this opportunity to provide comments on EPA's 

proposed regulations related to the management and disposal of coal combustion residues. As 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-38

proposed, this regulation will significl'\llt!Y impact the State of Kansas in numerous 

ways ·regardless of whether EPA decides to regulate disposal under Subtitle C or Subtitle 

D. Changes in either proposed option are needed to avoid unnecessary adverse impacts to state 

regulatory programs, private businesses, and human health and the environment. In general, this 

proposal, including the Subtitle D approach, applies a regulatory scheme which does not include 

the appropriate level of flexibility to consider and allow what is necessary and appropriate in all 

geologic and climatic settings.

This comment letter provides an overview of our Kansas concerns with the proposed regulation 

and some general suggestions for EPA's consideration. We have also prepared and attached 

detailed comments which provide information specifically requested by EPA as well as 

recommended regulatory language to replace some provisions in the proposed 

rule. 

Kansas is appreciative of the fact that EPA has requested input on the history of CCR 

management in the states and the extent of environmental harm caused by any past releases. We 

hope that the lack of incidents nationwide will influence EPA's fmal decision regarding the most 

appropriate regulatory approach.

Kansas has eight (8) coal-burning power plants that manage fly ash, bottom ash, and various air 

pollution control residuals in landfills and surface impoundments. Through more than 50 years 

of operating history, there has never been an incident where an environmental release has 

impacted surface water or groundwater. It is clear from this result that increased regulation will 

not yield any benefit. Human health and the environment has been adequately protected by the 

permitting laws and regulations that are presently in-place in Kansas.

At present, Kansas has a full system of waste and water permits and a beneficial use approval 

process to ensure that CCRs are properly managed to prevent impacts to human health or the 

environment. Kansas recognizes that all states may not have similar regulatory programs that 

provide these safeguards; however, EPA should not promulgate new CCR regulations that would 

adversely impact proven state regulatory programs such as in Kansas. Any federal regulations 

should establish minimum requirements to be applied to facilities in states where no approvable 

state regulatory program exists, but they should allow states to demonstrate that their regulatory 

programs are adequately protective.

The State of Kansas strongly encourages EPA to maintain the Bevell Amendment and regulate 

the disposal of CCR under SubtitleD rather than as a "special" hazardous waste under Subtitle 

C. We are opposed to Subtitle C regulation for several reasons. We believe regulation under 

Subtitle C will create a stigma for these wastes which impacts beneficial use decisions. Of even 

greater significance to Kansas is our present state law that prohibits the land disposal of any 

RCRA hazardous waste. If CCR is regulated under the hazardous waste rules, even if EPA uses 

the term "special waste," it is our interpretation that our state law would prohibit land disposal. 

All currently permitted disposal activities would become prohibited regardless of the standards 

which are applied to facility design. These wastes would need to be transported out of state for 

disposal. The costs and environmental impacts of this change in disposal practice would be 

enormous.
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-39

If the Kansas Legislature changed the existing law to allow disposal of "hazardous" CCR, other 

maj"or impacts would still occur. Every facility would need to submit new design and operating 

plans to KDHE and the RCRA permitting process would need to be implemented. KDHE does 

not have the staff to oversee this transition from the current solid waste permitting system to a 

new hazardous waste permitting system at eight separate power plants. The transition would also 

result in very high costs to power companies which will certainly be passed on to customers 

without any anticipated environmental benefits in Kansas.

While a Subtitle D regulatory approach is preferred by the State of Kansas, the proposed 

regulations under this approach also should be amended. The proposed regulations do not 

provide states with flexibility to consider alternative liners, leachate management methods, or 

final covers considering variable local conditions with respect to soil types, depth to 

groundwater, distance from surface water, and annual precipitation. The prescriptive one-size

fits-all conservative approach is unnecessary in areas where local conditions provide an adequate 

and preferred degree of natural protection.

We believe it is important for EPA to thoroughly examine existing CCR disposal 

permitting programs in Kansas and other states before concluding that a broad overhaul is 

needed as opposed to proper recognition and approval of state programs. Some information 

about the Kansas regulatory program follows. To obtain a permit for CCR management 

in Kansas and probably in many other states, a power company must provide the Bureau of 

Waste Management with comprehensive engineering plans, site geological information, a 

groundwater monitoring plan, a demonstration of financial assurance for closure and postclosure care, an operating plan, and other required permit application documents. When the 

waste storage units are constructed, the company must provide third party construction quality 

assurance to document that the units have been constructed in accordance with approved 

engineering plans. The permitting process also includes a public participation process consisting 

of a comment period and a public hearing.

In addition to the high degree of regulatory oversight by the KDHE solid waste permitting 

program, KDHE also routinely inspects these facilities. KDHE inspects all permitted solid waste 

storage or disposal areas at least one time per year. During inspections, all waste 

management practices are evaluated with respect to applicable regulations and permit conditions 

and the integrity of the containment systems is visually examined. On an as needed basis, KDHE 

solid waste permit engineers also visit these facilities to assess compliance related to desigrt, 

construction, operations, and monitoring.

Additional state regulatory agency inspections are also performed by the K nsas Division of 

Water Resources (DWR). Every three years, DWR inspects dam integrity at facilities that meet 

the following criteria: (1) the dam or berm must be greater than or equal to 25 feet in height or 

(2) the dam or berm must be at least 6 feet high and retain 50 acre-feet of liquid.

Kansas would also like to emphasize that states are best equipped to make beneficial use 

determinations for CCR, whether the uses are in construction or agricultural applications. EPA's 

rule should include provisions to delegate this responsibility to states along with the authority to 

issue permits for disposal areas (both landfills and surface impoundments) under Subtitle D.
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

In summary, Kansas believes the best approach to regulating CCR nationally is to develop 

regulations under SubtitleD, including a required permitting program, that can be 

administered by states. The permitting program should allow states flexibility to consider local 

conditions as they relate to the desigu of liners, leachate management, and final covers. The 

beneficial use aspects to this rule should also be delegated to approved state agencies.

The currently proposed rule will not yield any significant benefits to the citizens of Kansas who 

have never been impacted by CCR management under the existing regulatory system, but it 

could greatly impact our use of limited state resources and cost our businesses and citizens a 

great deal of money. The Kansas program could serve as a model for federal regulation under 

Subtitle D with provisions for states to exercise appropriate flexibility to administer their 

program based upon their own unique geology and climate.

(Note: Format used in this documentBold font is for excerpts from the Federal Register of EPA's preamble and proposed rule. 

Normal text that follows the bold font is Kansas' response/comments/suggested language)

The comments included in this attached address many details of the proposed regulation as well 

as information requested by EPA in the June 21, 2010 Federal Register proposal. Kansas' overall 

perspective on this regulation including a summary of key concerns is addressed in the cover 

letter which has also been submitted.

Preamble: Coal Combustion Residuals: Disposal

There are three key areas of analyses where EPA is seeking comment:

(1) The extent of existing damage cases

(2) The extent of the risks posed by the mismanagement of CCRs

(3) The adequacy of State programs to ensure proper management of CCRs (e.g., is groundwater 

monitoring required of CCR landfills and surface impoundments). p.35133

Kansas' response/comments
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

(1) History of CCR management in Kansas shows no evidence of environmental damage: Since 

1976 all industrial landfills in Kansas have been required to have solid waste permits. Designs 

submitted as part of permit applications must be prepared by licensed professional engineers and 

licensed geologists and reviewed by regulatory staff that is licensed as professional engineers 

and geologists. From 1976 until the present (2010), CCRs have been managed in permitted 

landfills, surface iinpoundments and piles. All disposal areas include groundwater quality 

monitoring systems. During the past 34 years. Kansas has had no known cases of environmental 

damages due to the mismanagement of CCRs as described and referenced in the Appendix to the 

Preamble Co. 35234- 35239).

(2) Extent of risk posed by the management of CCRs in Kansas:

Based on the successful record of CCRs management in the State of Kansas under existing solid 

waste statutory and regulatory authority (which includes engineering permitting, operations, 

construction quality assurance, groundwater quality monitoring, closure and post closure care, 

and financial assurance requirements), there is no unacceptable risk posed under current 

management requirements for CCRs in Kansas.

(3) Kansas' regulatory program for managing CCR disposal to date:

Historical information shows that the State of Kansas has had no known cases of environmental 

damage. Successful management of CCRs in Kansas can be attributed to a combination of three 

major factors I) responsible utility management, which includes their engineering staff, teclmical 

support personnel, quality design and construction work by engineers, geologists and contractors 

working for utility management, 2) professional engineering and professional hydrogeology 

staffs of the Kansas Department of Health and Environment (KDHE) in the Division of 

Environment (air pollution control, solid waste and wastewater permitting and regulatory 

inspections) and 3) the Kansas Department of Agriculture's Division of Water Resources, (dam 

safety permitting and regulatory inspections). Kansas regulatory process for management of 

CCR is comprehensive and provides adequate protection and assures financial responsibility for 

closure, post-closure care and corrective action. The regulatory requirements have covered, and 

continue to require sound engineering design, construction quality assurance, operations, 

groundwater quality monitoring, engineered closure, post-closure care, and financial assurance to 

cover closure, post-closure care, and corrective action costs.

Preamble: Coal Combustion Residuals: Beneficial Uses

Preamble: Section 1: p. 35132

Historically, EPA bas proposed or imposed conditions on other types of hazardous wastes used 

in a manner constituting disposal (e:g., maximum application rates and risk-based concentration 

limits for cement kiln dust used as a liming agent in agricultural applications (see 64 FR 45639; 

August 20, 1999); maximum allowable total concentrations for non-nutritive and toxic metals in 

zinc fertilizers produced from recycled hazardous secondary materials (see 67 FR 48393; July 

24, 2002). Should EPA should establish standards, such as maximum/minimum thresholds, or

rely on implementing states to impose CCR site-specific limits based on front-end 

characterization that ensures individual beneficial uses remain protective?

Kansas supports the rights of states to impose CCR site-specific limitations for beneficial use 

purposes.

Preamble: Section 1: p.35137-35141

If materials characterization is required, what type of characterization is most appropriate? If the 

CCRs exceed the toxicity characteristic at pH levels different from the TCLP, should they be 

excluded from beneficial use? When are totals levels relevant?

The determination of what material characterization is most appropriate cannot be arbitrarily 

assigned. The circumstances of the intended beneficial use should dictate the proper 

characterization. For example, if a particular CCR was going to be used in conjunction with 

spent lime from municipal water treatment to stabilize soil for a confined animal feeding 

operation (CAFO), the pH of the resulting soil mixture would most likely not encourage the 

leaching of metals. In this case, TCLP or SPLP metals results would not be as relevant as the 

total metals concentration because the risk associated with such as use would come from the 

ingestion of soil by livestock and not the leaching of metals into surface or groundwater.

Preamble: Section 1: p. 35139

Whether EPA should fully develop a leaching assessment tool in combination with the Draft 

SW-8461eaching test methods described in Section I. F. 2 and other tools (e.g., USEPA's 

Industrial Waste Management Evaluation Model (IWEM)) to aid prospective beneficial users in 

calculating potential release rates over a specified period of time for a range of management 

scenarios.

Such a tool, as long as it is not mandated by federal regulation, would be a useful tool in 

evaluating the potential fate and transport of contaminants.

Preamble: Section IV: p. 35156-35157

If EPA determines that regulations are needed for the beneficial use of CCRs, should EPA 

consider removing the Bevill exemption for such uses and regulate these uses under RCRA 

subtitle C, develop regulations under RCRA subtitleD or some other statutory authority, such as 

under the Toxic Substances Control Act?

Kansas recommends that CCRs should not be removed from the Bevill exemption. Kansas has 

an incident-free history in the management of CCRs and does not believe that the failings of 

beneficial use programs in other states are indicative of the need to change current practices. 

Changes to the status of CCRs destined for beneficial use by the EPA would create a shotgun 

regulatory approach, punishing states like Kansas, who have had no issues with the management 

of CCRs, for issues occurring in states east of the Mississippi River, who's geography,

predominant power plant designs, and climate are not comparable to the Great Plains region of 

the United States.

Preamble: Section IV: p. 35160

The growth and maturation of state beneficial use programs and the growing recognition that 

the beneficial use of CCRs is a critical component in strategies to reduce GHG emissions taking 

into account the potentially changing composition of CCRs as a result of improved air 

pollution controls and the new science on metals leaching.

The state of Kansas does not currently mandate an inventory of GHG emission reduction 

activities, nor does the state have plans to link the beneficial use of CCRs to GHG emissions. 

Additionally, Kansas is not pursuing the advance of the "new science" of metals leaching and 

will instead continue to use the TCLP and SPLP tests until the EPA, ASTM, or other governing 

science body properly develops and vets a new metals leaching protocol.

Preamble: Section IV: p. 35162-35163

Information and data relating to the agricultural use of FGD gypsum, including the submission 

of historical data, taking into account the impact of pH on leaching potential of metals, the 

variable and changing nature of CCRs, and variable site conditions.

Currently Kansas has two power plants that generate FGD gypsum, both located in the eastern 

third of the state. While there are two geographic regions of the state that could benefit from the 

addition ofFGD gypsum to agricultural fields (sodic soils in south central Kansas and heavy clay 

glacial till soil in northeast Kansas), there have been no requests submitted to the state to use 

FGD gypsum as a soil amendment. In the event that the state were to receive a request for such a 

beneficial use, the evaluation of the FGD gypsum would not be different from the evaluation of 

any other waste material destined for land application. Factors such as metals concentration and 

loading, rate and volume of application, location, and climate would all be taken into account.

Additionally, gypsum (and FGD gypsum) is highly soluble when applied to agricultural fields in 

non-arid regions, so the leachability of metals from FGD gypsum is not as important as the total 

metal concentration.

Preamble: Section IV: p. 35163

Information and data on the extent to which states request and evaluate CCR characterization 

data prior to the beneficial use of unencapsulated CCRs.

Kansas has not had any requests for the unencapsulated beneficial use of CCRs and does not 

have a set protocol on the testing of CCRs for such uses; however, the fluid nature of the 

beneficial use program in the state allows regulatory staff to evaluate each potential use scenario 

and adjust the testing requirements to fit that particular use scenario.

Preamble: Section IV: p. 35163
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-44

The appropriate means of characterizing beneficial uses that are both protective of human 

health and the environment and provide benefits. EPA is also requesting information and data 

demonstrating where the federal and state programs could improve on being environmentally 

protective and, where states have, or are developing, increasingly effective beneficial use 

programs.

The volume of beneficial use requests, including those involving CCRs, in the state of Kansas, 

taken in conjunction with the variability of the requests, has created a situation where a "one size 

fits all" approach to beneficial use request evaluation is not feasible. The two predominate 

beneficial uses requested in Kansas are for agricultural and civil engineering purposes, though 

requests involving CCRs have been almost exclusively in the latter category. The evaluation of 

beneficial use requests begins the same for each of these two main categories. The entity 

requesting the beneficial use determination must prove that 1) the material is not hazardous 

based on RCRA definitions and supporting analytical laboratory data (typically TCLP tests) and 

2) that the intended beneficial use is not a veil for disposal. If the beneficial use request passes 

these two criteria, Kansas regulatory staff then looks at the specific intended beneficial use and 

develops additional laboratory testing criteria and use restrictions to ensure reasonable human 

and environmental protection.

Given the above approach for evaluating and approving beneficial use requests, the state 

of Kansas would be hesitant to create a more regimented protocol that would not allow each 

beneficial use request to be evaluated on its own set of unique circumstances. Additionally, 

CCR beneficial use requests are not required for "typical" applications, i.e. use of fly ash as a 

concrete admixture or use of bottom ash as sandblasting media. Forcing such approvals into a 

situation where staff must review each and every request, even for uses that have been 

considered standard by industry groups such as ASTM or ASCE, would cause undue burden to 

state regulatory staff already taxed by declining state budgets and workforce reductions.

Preamble: Section IV: p.35163-35164

Whether certain uses of CCRs (e.g., uses involving unencapsulated uses of CCRs) warrant 

tighter control and why such tighter control is necessary.

Under the current system of beneficial use determination in Kansas, this point is moot. All 

requests to beneficially use any waste material, CCRs and otherwise, are evaluated with human 

health and environmental protection in mind first and foremost.

Preamble: Section IV: p.163-164

Whether it is necessary to define beneficial use better or develop detailed guidance on the 

beneficial use of CCRs to ensure protection of human health and the environment, including 

whether certain unencapsulated beneficial uses should be prohibited.

Unencapsulated use of CCRs, as long as they can be proven to be genuine beneficial uses and not 

guises for disposal, would be evaluated and regulated by the state of Kansas. Broadly 

restricting a category of potential beneficial use based on a few regionally grouped incidences

of mismanagement goes against the precepts of innovation credited to waste reduction initiatives 

put in place by many states. Such prohibitions of usage should be left to each state, where 

factors such as precipitation, soil chemistry, and CCR composition and generation can be 

evaluated by regulatory staff that have expertise in these local issues.

Preamble: Section IV: p.35163-35165

Whether the Agency should promulgate standards allowing uses on the land, on a site-specific 

basis, based on site specific risk assessments, taking into consideration the composition of 

CCRs, their leaching potential under the range of conditions under which the CCRs would be 

managed, and the context in which CCRs would be applied, such as location, volume, rate of 

application, and proximity to water.

Currently, the beneficial use program in Kansas takes most of the listed factors into 

consideration when approving waste materials, including CCRs, for beneficial use/land 

application. Kansas places restrictions on the land application of any waste material, including 

setbacks from property lines, residences, surface waters, and water supply wells. Additionally, 

metals loading limits, rate and frequency of application, and soil conditioning and agronomic 

nutrient qualities are other factors that Kansas weighs when evaluating a beneficial use/land 

application request. Kansas does not view additional promulgated federal standards as necessary 

in the evaluation of beneficial use/land application requests since the current state program takes 

into account a high level of protection of human and environmental health.

Preamble: Financial Assurance: p. 35210

Kansas has had fmancial assurance requirements in effect for all solid waste landfills, including 

industrial landfills, since 1994. The financial assurance requirements address closure, postclosure care, and corrective action.

Subtitle C Option: p. 35254-35264

Kansas respectfully requests that EPA not regulate CCRs under hazardous waste regulatory 

authority (Subtitle C, Parts 261, 264, and 265, 268, and 270). Regulation under Subtitle C would

have major adverse impacts to Kansas. Kansas state law currently prohibits the issuance of 

permits for solid waste disposal facilities for Subtitle C wastes. If EPA chooses the Subtitle C 

approach, it will require all CCRs generated in Kansas to be shipped out of state at significant 

negative economic and environmental impacts. KDHE does not believe that the strict 

environmental standards of Subtitle C are needed to provide adequate protection of human health 

and the environment as related to CCRs management. The long history of safe CCRs waste 

management in Kansas under state laws and regulations that are substantially equivalent to the 

federal Subtitle D standards demonstrates that these regulatory standards are adequate and 

effective in protecting human health and the environment..

Location Restrictions W. 35241)

Rule as proposed

Sec. 257.60 Placement above the natural water table.

(a) New CCR landfills and new CCR surface impoundments and lateral expansions must be 

constructed with a base that is located a minimum of two feet above the upper limit of the 

natural water table.

(b) For purposes of this section, natural water table means the natural level at 

which water stands in a shallow well open along its length and penetrating the surficial deposits 

just deeply enough to encounter standing water at the bottom. This level is uninfluenced by 

groundwater pumping or other engineered activities.

For the geological conditions encountered in Kansas, and the location restrictions currently in 

Kansas solid waste regulations for siting all solid waste landfills, including Subtitle D municipal 

solid waste landfills, this proposed language is confusing and contradictory. Kansas requests this 

section to be modified to read as follows:

Sec. 257.60 Placement above the uppermost aquifer.

New CCR landfills and new CCR surface impoundments and lateral expansions must be 

constructed with a base that is located a minimum of five feet above the upper limit of the 

uppermost aquifer as defined in proposed regulation 257.40 and certified by a qualified 

groundwater scientist, professional geologist, or professional engineer.

engineer.

(2) For purposes of this section, composite liner means a system consisting of two components; 

the upper component must consist of a minimum 30-mil flexible membrane liner (FML), and 

the lower component must consist of at least a two-foot layer of compacted soil with a hydraulic 

conductivity of no more than 1x10-7cm/sec. FML components consisting of high

density polyethylene (HDPE) shall be at least 60-mil thick. The FML component must be 

installed in direct and uniform contact with the compacted soil component.

(3) For purpose of this section, hydraulic conductivity means the rate at which water can move 

through a permeable medium. (i.e., the coefficient of permeability).

(b) [Reserved]

For the geological and climatic conditions encountered in Kansas this proposed language is 

limiting and would not allow designs which can be equally protective while having 

the advantage of being sustainable indefinitely into the future. Capillary barrier designs using insitu materials and geosynthetic clay liners have been used successfully in Kansas landfills 

located in areas of low precipitation. Other liner designs consisting of compacted clay have been 

adequately protective as demonstrated by years of groundwater monitoring in areas of eastern 

Kansas with higher precipitation and more shallow groundwater. A composite Subtitle D liner is 

clearly not needed to protect groundwater or surface water in all geologic and climatic scenarios. 

States should have the flexibility to review and approve of alternative liner designs that will 

provide adequate protection. Therefore, Kansas requests that paragraph (a)(1) of this section be 

modified to allow alternate designs as follows:

1) With a composite liner, as defined in paragraph (a)(2) of this section and a leachate collection 

system that is designed and constructed to maintain less than a 30-cm depth of leachate over the 

liner or an alternate design approved by the Director of an approved state that demonstrates that 

leachate will be contained or managed in a manner that is protective of ground water and 

suiface water. The design of the composite liner and leachate collection system must be prepared 

by, or under the direction of, and certified by an independent registered, professional engineer.

Closure Criteria (p. 35252)

Section 257.100

Proposed Rule

(c) At closure, the owner or operator of a surface impoundment must:

(1) Eliminate free liquids by removing liquid wastes or solidifying the remaining wastes and 

waste residues;

(2) Stabilize remaining wastes to a bearing capacity sufficient to support the final cover; and

(3) Cover the surface impoundment with a final cover designed and constructed to:

(i) Provide long-term minimization of the migration of liquids through the closed impoundment;

(ii) Function with minimum maintenance; and

(iii) Promote drainage and minimize erosion or abrasion of the cover;

(iv) Accommodate settling and subsidence so that the cover's integrity is maintained; and

(v) Have a final cover system that meets the requirements of subsection (d).

Paragraph (d) of this section prescribes one cover design option and paragraph (e) authorizes an 

alternative final cover design. Therefore Kansas requests that paragraph (c)(v) be modified as 

follows:
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-50

(v) Have a final cover system that meets the requirements of subsection (d) or (e).

Proposed Rule

(d) For closure with CCRs in place, a final cover system must be installed at all CCR landfills 

and surface impoundments that is designed to minimize infiltration and erosion. The final cover 

system must be designed and constructed to:

(1) Have a permeability less than or equal to the permeability of any bottom liner system or 

natural subsoils present, or a permeability no greater than 1x10"5 em/sec, whichever is less, and

(2) Minimize infiltration through the closed CCR landfill or surface impoundment by the use of 

an infiltration layer that contains a minimum 18-inches of earthen material, and

(3) Minimize erosion of the final cover by the use of an erosion layer that contains a minimum 6-

inches of earthen material that is capable of sustaining native plant growth, and

(4) Minimize the disruption of the final cover through a design that accommodates settling and 

subsidence.

(e) The owner or operator of the CCR landfill or surface impoundment may select an alternative 

final cover design, provided the alternative cover design is certified by an independent 

registered professional engineer and notification is provided to the state and the EPA Regional 

Administrator that the alternative cover design has been placed in the operating record and on 

the owner's or operator's publicly accessible internet site. The alternative final cover design must 

include:

(1) An infiltration layer that achieves an equivalent reduction in infiltration as the infiltration 

layer specified in paragraphs (d)(1) and (d)(2) of this section, and

(2) An erosion layer that provides equivalent protection from wind and water erosion as the 

erosion layer specified in paragraph (d)(3) of this section.

For the geological conditions encountered in Kansas this proposed language could result in final 

covers needing to be composite caps incorporating a geomembrane. In several solid waste 

landfills in Kansas, post-closure maintenance of such cover systems has been challenging. Such 

cover systems are not sustainable indefinitely into the future. On the other hand, appropriately 

designed alternative final covers such as capillary barrier covers and evapotranspiration covers 

are being successfully used in Kansas and such covers are designed to be protective indefinitely 

into the future with minimal maintenance. EPA technical experts and trainers have been 

supportive of such covers being used for Subtitle D landfill and similar technical basis would 

apply to CCR landfills. Kansas requests that paragraphs (e)(1) and (e)(2) of section (e) be 

deleted and section (e) be modified to read as follows:

Subtitle D Prime Option must be Selected by EPA for the Final CCR Rule

Duke has reviewed both of the proposed rules (ELG and CCR Proposals) and has determined 

that the regulatory requirements will require the company to make significant modifications to 

the way it must manage CCR in surface impoundments. EPA can best coordinate the 

requirements of the ELG proposal and the CCR proposal by finalizing the CCR proposal 

selecting the Subtitle D Prime non-hazardous waste option and also providing a reasonable 

timeline for implementation. This determination will provide Duke Energy and other electric

utilities time to coordinate compliance planning for the two rules and continue to offer reliable 

service to its consumers.

The Subtitle D Prime option is the only alternative in the CCR Proposal that will effectively 

align and integrate the final CCR and ELG rules because it represents the only option that allows 

for the realistic possibility that CCR surface impoundments, that are in compliance with the 

applicable groundwater protection standards, will be able to continue operating beyond a fiveyear time period. Selecting the Subtitle D prime option would be consistent with the structure of 

the ELG Proposal, which contemplates the continued practice of managing legacy flyash, bottom 

ash, and flue gas control mercury wastewaters in impoundments that comply with existing BPT 

effluent limits.

In addition, the ELG Proposal contemplates that impoundments will remain in service as part of 

the wastewater treatment system for other regulated effluents including the low volume 

wastewater and combustion residual leachate. Given the continued role of surface impoundments 

for wastewater treatment under the ELG Proposal, it is necessary that EPA eliminate the 

requirement to initiate closure of a surface impoundment 30 days after the final receipt of CCR. 

If CCR surface impoundments continue to operate in a manner fully protective of human health 

and the environment, there is no reason why these impoundments should not be allowed to 

continue to operate as part of the wastewater treatment facility or serve other operational 

purposes. To accomplish this goal, EPA should finalize the CCR rule with the Subtitle D option 

that ensures the effective alignment and coordination with the final ELG rule.

Location Restrictions in the Proposed Subtitle D Prime Option of the CCR Rule must be 

Modified

Maintaining consistency and coordination between the two rules requires the continued operation 

of qualified impoundments under the CCR rule. Therefore, EPA must modify the final CCR Rule 

Subtitle D prime option such that existing surface impoundments are not subject to the full array 

of location restrictions. Duke Energy contends that an existing surface impoundment should

only be subject to the same location restrictions as those for existing landfills and should have 

the same opportunity to comply with these requirements through the demonstration of 

alternatives. In the preamble of the CCR proposal, EPA acknowledges that subjecting existing 

CCR surface impoundments to the full array of locations standards will cause many 

impoundments to close before the end of their useful lives.

Eliminate the Mandatory Retrofit and Closure Requirements for Existing Surface

Impoundments that are Meeting the Groundwater Protection Standards

 Liner Retrofit Requirement

EPA must eliminate the mandatory liner retrofit requirement in the Subtitle D option presented in 

the CCR Proposal. This provision requires that liners must be installed on existing surface 

impoundments within five years or the impoundment must begin closure. Retrofitting liners in 

surface impoundments is not economically feasible and would force the premature closure of the 

impoundments that manage CCR. Many of these impoundments are also part of the plant 

wastewater treatment system for legacy wastewaters allowed within the ELG rule, in addition to 

low volume wastewaters. Moreover, such impoundment water may be beneficially reused in 

certain plant processes. An accelerated closure of these impoundments would be counter to the 

continued wastewater treatment role that the ELG Proposal contemplates for surface 

impoundments.

 Closure Requirement

EPA must also modify the Subtitle D Prime option in the CCR Proposal by eliminating the 

requirement that an impoundment must commence closure within 30 days of the last receipt of 

CCR. Consistent with the points made above, this requirement would force the premature closure 

of impoundments that are otherwise serving critical treatment functions for specified low volume 

wastewaters and/or legacy CCR transport water under the ELG rule, or where impoundment 

water is beneficially reused for other operational processes. Assuming that the final ELG rule 

contains a no- discharge requirement for fly ash and/or bottom ash transport water, a facility 

would be required to cease the delivery of fly ash and/or bottom ash to its surface 

impoundments. If the impoundment no longer receives CCR, it would trigger the requirement for 

the impoundment to immediately begin closure even if the impoundment was continuing to 

operate in an environmentally sound manner.

The ELG Proposal expressly contemplates that certain low volume wastewaters, including 

legacy fly ash and bottom ash transport water can continue to be treated and discharged through 

the exiting impoundments, as long as compliance with existing BPT effluent limits are met. The 

CCR proposal must allow the surface impoundment to continue to serve as a critical component 

in the plant’s wastewater treatment system for these other regulated wastewaters including, but

not limited to, combustion residual leachate, low volume wastewater, legacy fly ash/bottom ash 

transport water and storm water. It is also important that an ELG requirement that causes a 

particular impoundment to cease receiving CCR not automatically initiate the unrelated 

requirement in the CCR rule that the impoundment immediately begin closure.

Duke recommends EPA amend the regulatory text in proposed 40 C.F.R. 257.100(j) to eliminate 

the requirement to implement closure if the impoundment is still being used to 

managed wastewaters streams consistent with the ELG rule, or its wastewater is otherwise 

being beneficially re-used as part of plant operational processes. The closure of the impoundment 

would not be triggered if the impoundment is no longer receiving any CCR wastewaters. Duke 

Energy contends that those surface impoundments still in operation would remain subject to 

continued groundwater monitoring and applicable corrective action requirements, so that any 

potential environmental issues would be addressed during the continued operation of the surface 

impoundment. EPA should establish, in the ELG proposal, a similar requirement for closure to 

be implemented under the RCRA Subtitle D permit once a surface impoundment is no longer 

receiving wastewaters.

1.The ELGs should avoid duplication and overlap with the CCR Rule.

We appreciate EPA’s acknowledgement of the potential overlap between the new ELGs and the 

proposed Coal Combustion Residuals (CCR) Rule, both of which will regulate management of 

CCRs in surface impoundments. In adopting final ELGs, we urge EPA to avoid duplication, 

overlap, and conflicting requirements between these two environmental programs. Specifically, 

structural integrity requirements for surface impoundments are best addressed as part of the 

pending CCR Rule. The proposed Best Management Practices (BMPs) for surface impoundment 

structural integrity should be omitted from the final ELGs as unnecessary and duplicative. We 

also urge EPA to prevent the premature closure of CCR surface impoundments and to enable 

such impoundments to continue to manage and receive specified wastewaters as contemplated 

under the ELG Proposal by:

1. selecting the Subtitle D Prime option in the final CCR rule to enable CCR 

impoundments, which meet applicable groundwater monitoring and corrective action 

requirements, to remain operational and;

2. modifying the proposed Subtitle D Prime rule to ensure application of only specified 

location restrictions to existing CCR surface impoundments; and

3. Revising the proposed Subtitle D rule to eliminate the requirement that CCR units 

automatically commence closure upon the cessation of the receipt of CCRs.

Furthermore, we recommend that EPA develop a mechanism to allow for State implementation

State is able to demonstrate to EPA that its CCR regulations are no less stringent than the final 

Subtitle D controls.

The Rule Needs to Allow for the Continued Treatment of “Legacy Wastewater”

EPA’s ELG proposal recognizes that certain “legacy” CCR transport waters, such as fly ash, 

bottom ash, and flue gas mercury control legacy wastewater, will continue to be managed in 

impoundments, subject to present BPT limits. See 78 Fed. Reg. at 34,461-63. As EPA 

recognizes, impoundments may be necessary both to treat “legacy” wastewater already in the 

impoundments and to treat other wastestreams (like combustion residual leachate or low volume 

waste) that do not require dry handling.

EPA should be careful, then, to allow ash ponds to remain in use as needed. This requires 

crafting the CCR rule so as not to require operators to commence closing ponds within 30 days 

of last receiving CCRs (75 Fed. Reg. 35,127, 35,252 col. 3 (June 21, 2010)) and not to require 

dredging and lining them within five years. Promulgating the “Subtitle D Prime” option in the 

CCR rulemaking is necessary to accomplish this.

1. The Revised Risk Assessment Using ELG ICR Data Will Support a D Prime Option or 

Will Support Regulation of CCR Disposal Under RCRA Subtitle D

In the proposed CCR Rule, EPA relied heavily on its Draft Human and Ecological Risk 

Assessment of Coal Combustion Wastes51 to support its Subtitle C option.52 As EPA explains in 

the ELG proposal:

...EPA did not have definitive data about the location, size, or age of the waste management 

units, nor on the type or composition of the wastes contained in surface impoundments.

Id. at 34,442 col. 1. Consequently, EPA used data thought to represent the industry, when, in 

fact, the outdated data EPA used was lacking in the assumptions and accuracy to properly 

represent the current universe of CCR management units across the industry. Now that EPA has 

acquired data across the industry through the 2010 “ICR” on the location, size, age and contents 

of surface impoundments containing CCRs, the “data could be used in EPA’s risk assessment for 

any CCR Rule in several ways that could significantly affect the results of that assessment.53

Southern agrees that EPA should update the CCR risk assessment using the new data. When 

EPA uses these new data in a manner that promotes sound science, Southern agrees with EPA 

that the updated results have the “potential to lower the CCR Rule risk assessment results by as 

much as an order of magnitude.”54 Southern urges EPA to update the CCR risk assessment with 

data from the ELG ICR, harmonize its conclusions with the final ELG requirements, and in turn 

“provide strong support for a conclusion that regulation of CCR disposal under RCRA Subtitle D 

would be adequate.”55

2. Structural Stability of Impoundments Should be Dealt with in the CCR Rule

EPA is considering requiring best management practices (BMPs) for surface impoundments that 

receive CCRs. The asserted legal authority would be § 306 for new sources and § 304(e) for 

existing sources. EPA also cites § 402(a)(2) and 40 C.F.R. §§ 122.44(k) and 122.41(e). EPA says 

BMPs are “critical” to preventing catastrophic releases like those at Martins Creek, 

Pennsylvania, and Kingston, Tennessee.

Clean Water Act § 304(e) provides that EPA may publish BMP regulations for any specific toxic 

or hazardous pollutant to control runoff, spillage or leaks, sludge or waste disposal, and drainage 

from raw material storage if they may contribute significant amounts of such pollutants to 

navigable waters.

The proposed BMPs would require inspections every seven days, plans for designing, 

constructing, and maintaining existing impoundments, plans for closure, periodic inspections, 

and annual certification that the construction, operation, and maintenance follows the approved 

plan. 78 Fed. Reg. at 34,466-67. When stability and safety issues are identified, corrective action 

would be required. Id. at 34,467 col. 1.

management and disposal of CCRs since 1992. Without State implementation of a 

Federal CCR rule, plants in Pennsylvania would be faced with two different regulatory 

requirements for CCRs;

IV.THE GYPSUM ASSOCIATION SUPPORTS EPA'S INTENTION TO CONTINUE TO 

REGULATE CCRs UNDER SUBTITLE D

While the Proposed ELG Rule focuses primarily on the eight regulatory options for regulating 

wastewater from electric utilities, it also includes an important discussion on a related 

rulemaking regarding CCRs. As discussed above, EPA is properly reviewing the Proposed ELG 

Rule and Proposed CCR Rule together to understand what impact the two rulemakings will have 

on human health and the environment, as well as the regulated community. As part of that 

coordinated review, EPA has suggested that the new regulatory requirements laid out in the 

Proposed ELG Rule may allow CCRs to continue to be regulated under Subtitle D of RCRA. 78 

Fed. Reg. at 34442. In particular, it is EPA's view that the new data that has been generated in 

connection with drafting the Proposed ELG Rule could lower the Proposed CCR Rule risk 

assessment and further provide support for Subtitle D regulation. Id.

The Gypsum Association maintains that Subtitle D regulation is appropriate irrespective of the 

outcome of the Proposed ELG Rule or corresponding new data. Indeed, the Gypsum Association 

advocated for such an outcome in its November 2010 comments on the Proposed CCR Rule. In 

those comments, the Gypsum Association provided a comprehensive overview of external and 

internal environmental, health and safety studies that have repeatedly affirmed the safety of FGD 

gypsum and FGD wallboard. In connection with its review of and comments on the Proposed 

CCR Rule, the Gypsum Association retained ARCADIS, an environmental consulting firm, to 

evaluate data concerning FGD gypsum and determine whether FGD gypsum and FGD gypsum 

wallboard are safe and environmentally responsible. All publicly available data regarding FGD 

gypsum were reviewed, as was the Proposed CCR Rule and its underlying data. Based on that 

review, ARCADIS found that FGD gypsum simply is not RCRA hazardous. Moreover, 

ARCADIS concluded that none of the analyses relied upon by EPA presented any scientifically 

defensible information suggesting that FGD gypsum poses an environmental or human health 

concern. Instead, all available data confirm the safety of the product. Therefore, regulation of 

FGD gypsum under Subtitle D remains the appropriate approach regardless of which regulatory 

option is selected for the Proposed ELG Rule or consideration of the new utility data. Further, 

the data strongly support the explicit regulatory exemption for FGD gypsum that the Gypsum 

Association has proposed.

In the absence of any real risk to human health or the environment, regulation of all CCRs as 

non-hazardous waste under Subtitle D of RCRA remains the appropriate approach. However, as 

discussed in detail in the Gypsum Association's comments on the Proposed CCR Rule, even if 

EPA were to maintain the Subtitle D approach, there remains uncertainty about regulation of 

FGD gypsum. To avoid ambiguity and confusion and consistent with EPA's stated intent not to 

regulate beneficially-reused CCRs such as FGD gypsum, the Gypsum Association is reiterating 

its request that FGD gypsum be specifically exempt from regulation under 40 C.F.R. § 

261.4(a). Specifically, the Gypsum Association proposes that EPA adopt the following language 

for a specific exemption: "The grade of FGD gypsum used in the manufacture of gypsum

The Gypsum Association appreciates the opportunity to provide comments on EPA's Proposed 

ELG Rule. The Agency is appropriately conducting this rulemaking in tandem with the 

Proposed CCR Rule. This concurrent review allows for the correct characterization of CCRs as 

non-hazardous waste that should continue to be managed under Subtitle D of RCRA. However, 

since FGD gypsum is a manufactured product and not a waste, the Gypsum Association 

reiterates its request for an explicit regulatory exemption excluding the material from the scope 

of any final CCR Rule.

Comment Excerpt: 

If regulated under the ELG, the only appropriate way to regulate CCR under the CCR rule is 

under the Subtitle D Prime Approach.

Since the proposed ELGs do not contemplate any of the waste streams as generating a hazardous 

waste as defined under RCRA, the only option suitable for CCR regulation are either the Subtitle 

D or Subtitle D Prime options listed in the proposed CCR rules published by EPA. However, the 

Subtitle D option is not tenable given that waste water impoundments sometimes serve multiple 

purposes. Therefore, it is imperative that the CCR rule not compel the premature closure of 

impoundments meeting applicable groundwater monitoring or corrective action requirements. 

Only the Subtitle D Prime option offers this possibility. Xcel Energy strongly supports the 

Subtitle D Prime option and urges EPA to select the Subtitle D Prime option for the CCR 

rulemaking process.

Comment Excerpt: 

Critical for EPA is to effectively align and integrate the final CCR rule with the final ELG rule is 

the selection of the Subtitle D Prime option in the final CCR rule. This is because of the options 

presented within the proposed CCR rule, only the Subtitle D Prime option provides for the 

possibility of surface impoundments to remain in operation. A CCR rule that results In the 

mandatory and premature closure of impoundments that are otherwise operating in a protective 

manner would be inconsistent with the contemplated future role of Impoundments in the ELG 

rule.

In addition, the final Subtitle D Prime rule should be changed so that existing surface 

impoundments are not subject to the full array of location restrictions, but rather are subject to 

the same location restrictions as those for existing landfills-i.e., the floodplain and unstable area 

location restrictions. {Federal Register, June 21, 2010, Page 35198). In the preamble to the CCR 

Proposal, EPA acknowledges that subjecting existing CCR surface impoundment to the full array 

of locations standards including (In addition to the two above) wetlands, fault areas and seismic 

impacts areas, could cause surface impoundments to close. Id. at 35199. The accelerated closures 

of these impoundments would be at odds with the continued role that the ELG Proposal 

contemplates for impoundments under that rule.

Another important modification to the CCR Proposal necessary to ensure coordination between 

the final CCR and ELG rules is the elimination of the requirement to be codified at 40 C.F.R. § 

257.100(j))in the CCR Proposal compelling an impoundment to commence closure within 30 

days of thelast receipt of CCR. (FederalRegister, June 21, 201O,Page 35252). This proposal 

appears to be based on the assumption that CCR units that permanently cease to receive CCR 

will stop functioning as a management or disposal unit. However, this requirement would force 

the premature closure of impoundments that are otherwise serving critical treatment functions for 

specified wastewaters under the legacy provisions of the ELG rule.

generally confirm that EPA‟s concerns about CCR impoundment failures are overstated in the 

CCR risk assessment. EPA states that only those ranking “unsatisfactory” pose an immediate 

safety threats,29 and yet not a single surface impoundment received a ranking of 

“unsatisfactory.”30 Less than one third of the impoundments inspected received a ranking of 

“poor.” Some units received a “fair” or “poor” rating solely due to a lack of detailed design or 

construction data, where they may otherwise be structurally sound. EPA's 

CCR rule risk assessment overestimates the actual threat surface impoundments pose to human 

health and the environment.

During the inspection process, EPA encouraged facilities to respond to the inspection reports and 

prepare action plans. Nearly all assessed CCR surface impoundments have completed their 

action plans to implement recommendations made by the dam integrity contractors to improve 

operation and maintenance of the surface impoundments. MidAmerican believes this information 

must be used to update the CCR rule risk assessment to provide an accurate representation of the 

current conditions of CCR surface impoundments. An updated risk assessment will appropriately 

show that surface impoundments pose less of a safety threat than was initially assumed.

When the completed action plan information is incorporated into the risk assessment model, the 

lower risk assessment results will not support the surface impoundment liner retrofits required in 

Subtitle D. It is clear that Subtitle D Prime is the only appropriate option for the regulation of 

CCR.

Comment Excerpt: 

Substantive requirements of a final CCR rule and the proposed ELG rule must be aligned to 

prevent the premature closure of CCR surface impoundments that meet applicable groundwater 

monitoring and/or corrective action requirements.

The ELG proposal allows for continued use of surface impoundments to manage wastewater and 

identifies the impoundments as the best practicable control technology currently available for 

several wastestreams, including legacy ash transport water, combustion residual leachate, and 

cooling tower blowdown. Under the proposed CCR rule, however, a facility must begin closure 

of an impoundment within 30 days of the last receipt of CCR.31 The requirement would force the 

closure of impoundments that are otherwise serving an important treatment function for 

wastewaters regulated under the ELG rule.

The date for initiating closure of a surface impoundment should not be based on its final receipt 

of CCR, but rather on when the impoundment ceases to serve a function under either the CCR 

rule or the ELG rule. EPA should amend the regulatory text of the CCR rule to eliminate this 

automatic closure requirement. The units will remain subject to structural integrity monitoring, 

groundwater monitoring, and corrective action requirements under the CCR rule. Any potential 

groundwater issues would be addressed during continued operation of a unit for the purposes of 

managing wastewater under the ELG rule. This approach would ensure that surface 

impoundments are operated in a manner that is protective of human health and the environment, 

while allowing them to continue serving a critical treatment function under the ELG rule.

This regulatory oversight has resulted in stigmatizing the beneficial use of coal ash, and 

translated into stagnation, job loss and an absence of investment in our recycling industry.

At EPA’s public hearings on the CCR Proposed Rule, EPA heard testimony from companies 

engaged in the sale of products in competition with products utilizing coal ash, in support of a 

hazardous designation for coal ash, given the favorable competitive advantage they stood to gain 

as a result of the ensuing stigma.3 EPA also heard testimony from hundreds of companies,

individuals, and organizations invested in the use of coal ash as a recycled material.4 Among 

them were coal ash marketers, suppliers, concrete and asphalt producers, as well as members of 

the agricultural and farming community.5 All were unanimous in their position that the future of 

their businesses would be critically impacted by EPA’s actions regarding the regulation of 

CCR’s. Additionally, many shared negative effects already materializing in the form of 

decreased investment, and a decline in sales resulting from an expressed fear of the liability 

attached to using a product with a potential hazardous designation.6 This stigma has displayed 

itself in other tangible forms, and has been fueled by companies selling competing non‐coal ash 

products, such as lightweight concrete block manufacturers labeling their product as containing 

no hazardous bottom ash, as well as clay brick manufacturers attacking fly ash brick as 

hazardous.7 Ash marketers have also reported an increased demand by utilities for 

indemnification protection against claims that may arise from utilization of coal ash.8 Many 

companies within the CCR recycling community are small businesses. Numerous jobs have been 

lost. One publicly traded company in the CCR recycling niche has seen significant stock price 

erosion.9

In addition, the sale of CCR’s for the purpose of beneficial use contributes $6 -

11 billion annuall to the U.S. economy through the 

concrete industry, wallboard industry, asphalt products industry, and road and bridge constructio

n.10 According to a study 

commissioned by the Utility Solid Waste Action Group, the concrete industry employs 240,100

manufacturing workers, 78,480 

foundation, structure and building exterior workers, as well as a number of the approximately 10

2,350 nonresidential building construction workers.11 The wallboard industry employs over 

113,000 workers in manufacturing, drywall installation, and taping.12 The asphalt products 

industry provides employment for approximately 191,000 in manufacturing, paving, roofing and 

equipment operation. In 2010, road and bridge construction accounted for 75,290 highway, 

street, and bridge construction jobs.13 It is estimated that, allowing the coal ash recycling 

industry to remain in such a precarious position by not considering the impact of these proposed 

regulations risks the loss of between 183,900 and 316,000 of these jobs.14

EPA’s purpose requires the agency to consider impacts of its rulemaking on the beneficial 

use of CCRs.

EPA’s statement of purpose includes the following objectives:

 That “federal laws protecting human health and the environment are enforced fairly and 

effectively;

 environmental protection is an integral consideration in U.S. policies concerning natural

environmental policy;

 environmental protection contributes to making our communities and ecosystems diverse, 

sustainable and economically productive; and

 the United States plays a leadership role in working with other nations to protect the

Failure to fully consider the impact of EPA’s CCR disposal rulemaking on beneficial use would 

be counter to each of these objectives.

Comment Excerpt: 

The enabling statute under which this rulemaking is conducted presumes the importance 

and consideration of beneficial use of CCRs.

EPA’s proposed CCR disposal regulations are under the authority of the Resource Conservation 

and Recovery Act. The EPA office conducting the rulemaking has “Conservation and 

Recovery” in its name. Nevertheless, the NODA question on beneficial use seeks input on 

whether conservation and recovery should even be considered in its rulemaking.

In its findings establishing the Resource Conservation and Recovery Act, Congress stated: “The 

Congress finds with respect to materials, that— (1) millions of tons of recoverable material 

which could be used are needlessly buried each year; (2) methods are available to separate usable 

materials from solid waste; and (3) the recovery and conservation of such materials can reduce 

the dependence of the United States on foreign resources and reduce the deficit in its balance of 

payments.”17

Furthermore, Congress stated specific objectives for encouraging materials recovery and reuse 

throughout Solid Waste Disposal Act.18

If EPA fails to consider impacts on materials recovery and beneficial use from its CCR disposal 

rulemaking, the agency will be in direct opposition to the letter and spirit of the Act from which 

it derives its rulemaking authority.

*In, the August 2nd, 2013 CCR NODA under RCRA, EPA recently requested comment on 

whether it should add requirements to "overfills" which would greatly increase the costs and 

decrease the viability of overfills. EPA has coined the term overfills to describe the process 

whereby an existing fly ash pond is converted to a dry landfill, by placing a vertical expanded lift 

of dry fly ash on top of the previously ponded ash. EPA has requested input on how it should 

require final cover over "closed" ash ponds and whether it should require a double composite 

liner between the "closed" ash pond and the new overfill. Even though DTE's Monroe ash pond 

already has an existing liner beneath the existing ash fill, EPA's new RCRA regulation could 

conceivably require in addition the natural clay liner beneath the existing bottom ash basin:,

 a final cover over the existing fill,

 a composite liner between the existing fill and vertical extension or overfill and

 a final, 2nd cover, on top of the overfill.

 Since the plastic in any composite liner could not be placed over the existing 

unconsolidated fill without extensive and expensive pre-compaction, an additional 

expense would be incurred.

DTE commented on the enormous costs and inappropriateness of such a design and pointed out 

that it could well preclude the overfilling of the existing on site facility and drive the company to 

a new off-site greenfield landfill. DTE reiterated its 2010 RCRA comments that the existing 

natural clay liner beneath the existing ash pond should be a sufficient liner for both the ash pond 

and overfill, and the new cover of the overfill should be a sufficient cover for both the ash pond 

and overfill.

Moreover, to ensure that such dry wastes do not then filter into the environment from landfills, 

the EPA must also classify coal ash as the hazardous waste that it is, under the Resource 

Conservation and Recovery Act (RCRA). Only by taking these steps can the EPA truly begin to 

protect public health, and the health of our wildlife and ecosystems, from the debilitating and

often lethal impacts of coal combustion residuals. As these toxic pollutants do not degrade in the 

environment and accumulate in the bodies of living organisms, we will only see more people and 

animals negatively impacted. The only way to slow the number of living things impacted by 

these toxic pollutants is to prevent them from entering the environment in the first place, and the 

best mechanism to prevent this is the Resource Conservation and Recovery Act (RCRA).

As EPA correctly recognizes, the final ELG and CCR rules will regulate or affect the same unit 

and/or activity—i.e., the management of CCR in surface impoundments. Therefore, USWAG 

appreciates EPA’s request for comment on its views for how to harmonize these two 

regulations. As explained in Section II below, USWAG believes that harmonization of the two 

rules requires:

 Selection of the Subtitle D Prime option in the final CCR rule to enable CCR 

impoundments, that meet applicable groundwater monitoring and corrective action 

requirements, to remain operational and to continue to manage and receive specified 

wastewaters as contemplated under the ELG Proposal;

 Modification of the proposed Subtitle D Prime Rule to ensure application of only 

specified location restrictions to existing CCR surface impoundments to prevent the 

premature closure of such impoundments and to enable the impoundments to remain 

operational and to continue to manage and receive specified wastewaters as contemplated 

under the ELG Proposal;

 Modification of the proposed Subtitle D rule to eliminate the requirement that CCR units 

automatically commence closure upon the cessation of the receipt of CCR in order to 

prevent the premature closure of such units under the final CCR rule;

A. Coordination of Substantive Requirements

EPA’s evaluation of how to harmonize the substantive requirements of the CCR and ELG rules 

focuses on how to coordinate the requirements for surface impoundments because these units 

will be regulated under both rules. Id. at 34441. In particular, EPA is evaluating how facilities 

will modify their operations to comply with the ELG rule and then will factor those results into 

determining “whether separate RCRA requirements under the CCR rule are needed to ensure 

protection of human health and the environment.” Id. For example, EPA explains that “[w]hile 

the ELG would not compel the use of a particular technology, EPA predicts that one possible 

consequence of the proposed ELG requirements is that some number of facilities will choose to 

convert their sluicing operations to dry ash-handling systems, and will no longer send such 

wastes to surface impoundments.” Id. Given the possibility that some facilities “would no 

longer need to operate surface impoundments, it is possible that this might affect the time frame 

(or other requirements) necessary for closure of such impoundments” under the final CCR rule. 

Id. at 34442.

Assuming that the final ELG rule results in some facilities ceasing the management of certain 

CCR transport waters in surface impoundments, there should be corresponding modifications in 

the substantive requirements for surface impoundments in the final CCR rule. Reduced use of 

impoundments for the management of CCR necessarily will reduce the risk of potential CCR 

groundwater contamination from these impoundments. This consequence must be considered for 

purposes of a final CCR rule.
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-70

In addition, as discussed below and addressed in detail in USWAG’s comments recently filed in 

response to EPA’s Notice of Data Availability in the coal combustion residuals rulemaking 

(“CCR NODA”), it is expected that the modeled risks from CCR impoundments identified in 

EPA’s draft CCR risk assessment will be substantially reduced in the final CCR risk assessment 

based on the more comprehensive data on CCR management collected by the Agency in 

response to the ELG information collection request (“ICR”). Id. at 34442. Given that the ELG 

rule may result in a reduction in the future role of some impoundments managing CCR transport 

waters, coupled with what USWAG (and EPA) believes will be a significant reduction in the 

CCR risk assessment associated with such units, there are compelling reasons to significantly 

modify the requirements for CCR surface impoundments in the final CCR rule. Given the above, 

USWAG’s suggestions for EPA selecting the Subtitle D Prime option and modifying the 

requirements for surface impoundments in the final CCR rule are fully consistent with EPA’s 

goal of coordinating “any final RCRA requirements with the ELG requirements, to minimize the 

overall complexity of these two regulatory structures, and facilitate implementation of 

engineering, financial and permitting activities.” Id. at 34441.

1. Harmonization of the CCR and ELG Rules Requires Selection of the Subtitle D Prime 

Option in the Final CCR Rule

USWAG believes that EPA’s selection of the Subtitle D Prime option in the final CCR rule is 

critical for EPA to effectively align and integrate the final CCR with the final ELG rule. This is 

because only the Subtitle D Prime option provides for the realistic possibility of surface 

impoundments continuing to operate to manage CCR, provided that applicable groundwater 

monitoring and corrective action requirements are met. The Subtitle D Prime option is necessary 

to align the final CCR rule with the structure of the ELG Proposal because the ELG rulemaking 

contemplates a future role for impoundments for purposes of managing legacy CCR transport 

waters, as well as serving as part of the ELG treatment train for other specified 

wastewaters. Indeed, any CCR rule that results in the mandatory and premature closure of 

impoundments that are otherwise operating in a protective manner would be inconsistent with 

the contemplated future role of impoundments in the ELG rule. Failure to align the rules in this 

manner will result in serious compliance concerns and create an unnecessarily complex 

regulatory structure, both of which are inconsistent with the directions in RCRA Section 

1006(b).

(a). The Technical Record Supports the Subtitle D Prime Option

Before elaborating on the above point, USWAG would like to emphasize that new 

data referenced in the ELG Proposal clearly demonstrate that, strictly from a risk perspective, the 

Subtitle D Prime option is now the more technically justified option of the two Subtitle D 

choices presented in the CCR Proposal. Under the Subtitle D Prime option, existing surface 

impoundments can continue to operate for the remainder of their useful lives, provided they 

continue to meet all applicable groundwater monitoring and any associated corrective action 

requirements. 75 Fed. Reg. at 35210. Under the Subtitle D Prime option, any groundwater 

contamination threats from an impoundment during its operating life and during post-closure 

would be detected and appropriate corrective action would be taken. In all other respects, the 

Subtitle D Prime and the alternative Subtitle D option are identical.
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-71

In contrast, under the alternative Subtitle D option, all existing surface impoundments would 

have to be dredged of CCR and retrofitted with a composite liner within five years of the 

effective date of the regulations, or close. Id. at 35244 (proposed to be codified at 40 C.F.R. § 

257.71(g)). As EPA is aware, however, the draft CCR risk assessment is the technical basis for 

the proposed requirement in the alternative Subtitle D option that all existing impoundments be 

retrofitted or closed within 5 years. See id. at 35202 (discussing Subtitle D design requirements 

and stating that the “quantitative groundwater risk assessment” clearly shows “the need for 

effective liners—namely composite liners—to very significantly reduce the probability of 

adverse risks” from CCR impoundments). As EPA readily acknowledges, though, 

the preliminary conclusions in the draft CCR risk assessment have been thrown into 

considerabledoubt due to the more comprehensive data on CCR management collected by the 

Agency in response to the ELG ICR in the ELG rulemaking. 78 Fed. Reg. at 34442. Indeed, 

EPA acknowledges that the incorporation of these new data into the CCR risk assessment model 

“have the potential to lower the CCR rule risk assessment results by as much as an order of 

magnitude.” Id.

To this point and as noted above, USWAG filed comments in the recent CCR NODA regarding 

how the ELG ICR (and other) data should be used in modifying the final CCR risk 

assessment. 78 Fed. Reg. 46940 (Aug. 2, 2013). USWAG retained Gradient to conduct a critical 

review of the new data to assess how their proper incorporation into EPA’s risk model would 

influence the final CCR risk assessment (the Gradient report, entitled “The Implications of US 

EPA’s Notice of Data Availability (September 3, 2013) on the Human and Ecological Risk 

Assessment of Coal Combustion Wastes,” is an attachment to USWAG’s comments in the 

CCR NODA docket2and is attached to these comments as well). The Gradient report confirms 

that EPA was correct in suggesting that the new information referenced in the NODA 

substantially reduces the alleged risks reflected in the CCR risk assessment associated with the 

disposal of CCR in landfills and surface impoundments.

The Gradient report makes clear that a revised CCR risk assessment that properly incorporates 

the new data referenced in the NODA can no longer support EPA’s proposal to regulate CCR as 

Subtitle C hazardous waste or to impose a mandatory retrofit requirement for all unlined CCR 

surface impoundments under the Subtitle D option. The Gradient report explains that the revised 

risk assessment, when adjusted to reflect the more comprehensive and realistic data regarding 

CCR management practices referenced in the NODA, results in a significantly lower risk from 

CCR management units which supports the Subtitle D Prime option and cannot be used to 

support the Subtitle C option or the mandatory retrofit option for all impoundments under the 

Subtitle D option. Given this new information, USWAG submits that the final CCR risk 

assessment and the corresponding CCR rulemaking record will provide compelling technical 

justification for EPA to select the Subtitle D Prime option in the final CCR rule.

(b). The Subtitle D Prime Option is Necessary to Align the CCR and ELG Rules

In addition to the above, the Subtitle D Prime option is necessary to effectively align and 

integrate the final CCR and ELG rules because, as noted above, only the Subtitle D Prime option 

allows for the realistic possibility that most CCR surface impoundments will be able to continue 

operating beyond a five-year time period. This strategy is consistent with the structure of the 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-72

ELG Proposal, which expressly contemplates that certain legacy CCR transport waters—

including, for example, fly ash, bottom ash and flue gas mercury control legacy transport 

waters —will continue to be managed in impoundments and remain subject to existing BPT 

effluent limits. See 78 Fed. Reg. at 34461, 34462, & 34464. Indeed, the technologies identified 

as the basis for the discharge requirements for the underlying wastewaters were not demonstrated 

for the corresponding legacy transport waters, so continued pond management of these waters is 

a critical component of the ELG Proposal. Id. In addition, the ELG Proposal contemplates that 

impoundments—even when no longer receiving certain CCR transport waters—will remain in 

service as part of the ELG treatment train for other regulated effluents, including, for example, 

bottom ash transport water (at least in three of the four preferred options) and combustion 

residual leachate. Id. at 34458. The premature closure of these impoundment systems at 

power plants will present a serious compliance dilemma for management of regulated 

wastewaters under the ELG rule.

Given the continued role of wastewater impoundment management under the ELG Proposal, it is 

absolutely critical that the final CCR rule not compel the premature closure of CCR surface 

impoundments that are meeting applicable groundwater monitoring and/or corrective action 

requirements. Only the Subtitle D Prime option offers this possibility under the CCR 

Proposal. Given that CCR impoundments can continue to operate in a manner fully protective of 

human health and the environment under this option, there is no reason for EPA not to pursue 

this choice and ensure the effective alignment and coordination between the two rules.

In contrast to the Subtitle D Prime option, EPA has made clear that one of the primary objectives 

of the mandatory retrofit or closure requirements under the alternative Subtitle D option is to 

compel the premature closure of CCR surface impoundments. See 75 Fed. Reg. at 35202 (in 

explaining the consequences of this requirement, the Agency stated that it “expects that many 

surface impoundments will choose to close rather than install a liner . . . .”). Given that such 

premature closure is not necessary to meet RCRA’s objective of protecting human health and the 

environment (especially given the reduction in risk from such units that will be reflected in a 

revised CCR risk assessment) and the important treatment function these ponds are expected to 

serve in the final ELG rule, USWAG urges EPA to select the Subtitle D Prime option in the final 

CCR Rule.

2. Harmonization of the CCR and ELG Rules Requires Tailoring of the Location Standards for 

Impoundments in the Final CCR Rule

Consistent with the principle that coordination between the CCR and ELG rules requires the 

continued operation of qualified impoundments under the CCR rule, it also is critical that EPA 

modify the final Subtitle D rule so that existing surface impoundments are not subject to the full 

array of location restrictions, but rather are subject to the same location restrictions as those for 

existing landfills—i.e., the floodplain and unstable area location restrictions. 75 Fed. Reg. at 

35198. In the preamble to the CCR Proposal, EPA readily acknowledges that subjecting existing 

CCR surface impoundment to the full array of locations standards including (in addition to the 

two above) wetlands, fault areas and seismic impacts areas, will cause “many” surface 

impoundments to close. Id. at 35199. As is the case with the CCR Proposal’s mandatory retrofit

requirements, such accelerated closures of these impoundments would be directly at odds with 

the continued role that the ELG Proposal contemplates for impoundments under that rule.

Furthermore, as we addressed in our comments on the 2010 proposal, USWAG does not believe 

that EPA has conducted research or compiled record evidence suggesting that there is any need 

to retroactively apply the additional location restrictions applicable to new units (i.e., wetlands, 

fault areas and seismic impact zones) to existing surface impoundments. Because these units 

have not been shown to have problems addressable by the imposition of the additional location 

restrictions for new units, these additional restrictions should not apply to existing 

impoundments. Rather, imposing these requirements on existing impoundments will serve only 

to limit the options contemplated in the ELG Proposal for the management of legacy transport 

waters and other regulated wastestreams in these units.

To avoid this inconsistency and the lack of record evidence supporting these additional 

restrictions, USWAG urges EPA to amend the final Subtitle D rule by tailoring the application of 

the location restrictions for existing CCR impoundments to mirror those applicable to existing 

CCR landfills—i.e., floodplains and unstable areas. Importantly, application of the fully array of 

location standards to existing CCR surface impoundments are not necessary to ensure their 

structural stability. Rather, the combination of the CCR Proposal’s structural 

stability requirements for all existing surface impoundments, see 75 Fed. Reg. at 35243, 35245 

(proposed to be codified at 40 C.F.R. §§ 257.71 & 257.83), together with the application of the 

unstable area location restriction to these impoundments will ensure that any potential structural 

deficiencies in a CCR impoundment are detected and corrected.

The CCR Proposal’s structural stability requirements are modeled on the long-standing Mine 

Safety and Health Administration (“MSHA”) dam safety requirements and require, among other 

things, an annual certification by an independent registered professional engineer to ensure that 

the design, operation, and maintenance of the impoundment is in accordance with current, 

prudent engineering practices for the maximum volume of CCR which can be impounded in the 

unit. Id. at 35245. This is in addition to the proposed requirement that impoundments be 

inspected on a regular basis to ensure that any potentially hazardous condition or structural 

weakness is quickly identified and addressed. Id. Indeed, EPA observed that the proposed 

structural stability requirements in the Subtitle D proposal “are necessary to ensure that major 

releases [from CCR impoundments] do not occur that would cause adverse effects on health or 

the environment.” Id. at 35203.

Given the above, USWAG urges EPA to tailor the location restrictions for existing surface

impoundments to include those for floodplain and unstable area locations. These location 

restrictions, along with the MSHA-based structural stability requirements for all CCR surface 

impoundments, will ensure the early detection and response to potential impoundment structural 

stability issues, while also allowing for the proper integration and harmonization of the 

requirements in the final CCR and ELG rules.

To assist EPA in ensuring the harmonization of the CCR and ELG rules, USWAG provided EPA 

with proposed draft text for § 257.100(j)(1) clarifying that one of the potential triggering events 

for the closure of a landfill or surface impoundment is when it ceases to receive any waste (in 

addition to CCR) it is permitted to manage. We reiterate our suggested language below.

SUGGESTED TEXT FOR INITIATING CCR UNIT CLOSURE:

40 C.F.R. § 257.100 Closure Criteria

. . . .

(j) (1) Subject to paragraph (2) of this subsection, the owner or operator of a CCR landfill or 

surface impoundment must commence closure activities thirty days after the final known receipt 

of a waste the unit is permitted to manage or within thirty days after the conclusion of the 

functions authorized for such surface impoundment or landfill as set forth in a state-approved 

operating plan or other state authorization, whichever is later.

(2) If the CCR landfill or surface impoundment has remaining capacity and there is a reasonable 

likelihood that the unit will resume managing a waste, the unit must commence closure activities 

within two years after the most recent receipt of waste. This period may be extended in two year 

increments provided the owner or operator demonstrates in a written certification to the 

facility’s operating record and relevant state agency, at expiration of the initial two year period 

and every subsequent two year period as applicable, that the owner or operator has a reasonable 

belief that the unit will resume managing a waste.

D. Identification of Subtitle D as Likely Management Option for CCR Rule

USWAG read with interest EPA’s statement in the preamble to the ELG Proposal that 

development of the final ELG rules, combined with the anticipated reduction in the risk 

assessment for CCR, could have broad implications for the final CCR rule. Specifically, EPA 

stated that:

If this proves to be the case [i.e., a reduced risk in the CCR risk assessment], EPA’s current 

thinking is that, the revised risks, coupled with the ELG requirements that the Agency may 

promulgate, and the increased Federal oversight such requirements could achieve, could provide 

strong support for a conclusion that regulation of CCR disposal under RCRA Subtitle D would 

be adequate.

78 Fed. Reg. at 34442. USWAG obviously supports this statement and believes that the reduced 

risk assessment results for CCR alone will be sufficient for EPA to select the Subtitle D Prime 

option. We also must note, however, as made clear in our initial comments, that the Subtitle D 

option is the only legally viable option available to EPA in the final CCR rule. See USWAG 

CCR Comment at 41. Therefore, the real choice for EPA is not choosing between the Subtitle C 

and Subtitle D options, but rather which Subtitle D option to select. As explained above, to 

ensure consistency and integration between the final CCR and ELG rules, while continuing to 

protect human health and the environment, the Agency should select the Subtitle D Prime option.

Critical to the effective alignment and integration of the two rules is for EPA to select the

Subtitle D Prime option in the final CCR rule because only this option offers the realistic 

possibility of surface impoundments continuing to manage CCR. This regulatory option is 

necessary because the ELG rulemaking contemplates a future role for impoundments for 

purposes of managing legacy CCR transport waters, as well as serving as part of the ELG 

treatment train for other specified wastewaters. Therefore, it is important that nothing in the

XIV. The Rule Needs to Allow for the Continued Treatment of “Legacy Wastes”

EPA’s ELG proposal recognizes that certain “legacy” CCR transport waters, such as fly ash, 

bottom ash, and flue gas mercury control legacy waters, will continue to be managed in 

impoundments, subject to present BPT limits. See 78 Fed. Reg. at 34,461-63. As EPA 

recognizes, impoundments may be necessary both to treat “legacy” wastes already in the 

impoundments and to treat other wastestreams (like combustion residual leachate or low volume 

waste) that do not require dry handling.

EPA should be careful, then, to allow ash ponds to remain in use as needed. This requires 

crafting the CCR rule so as not to require operators to commence closing ponds within 30 days 

of last receiving CCRs (75 Fed. Reg. 35,127, 35,252 col. 3 (June 21, 2010)) and not to require 

dredging and lining them within five years. Promulgating the “Subtitle D Prime” option in the 

CCR rulemaking is necessary to accomplish this.

For example, the utilities were never asked about the location of wellhead protection areas 

nearby. Our comments specifically attempt to address the questions:

o Are ash ponds or landfills in aquifers (beneath the water table) and if so, are these 

aquifers used as a drinking water source by people nearby?

o How many private wells are nearby ash ponds?

o Are there public water supply wells nearby? How close are wellhead protection areas?

o How close are these wells to the ash disposal sites, and where are they located in relation 

to these sites, upgradient? downgradient? sidegradient?

o What effects might significant water withdrawal operations either individually or 

cumulatively have on groundwater flow directions from ash dump sites?

We do not think the United States Environmental Protection Agency (hereafter called “EPA”) 

should make decisions to reduce the risk modeled in its Human and Ecological Risk Assessment 

“by as much as an order of magnitude” without even having asked any of these questions in its 

2010 Information Collection Request or comprehensively attempted to gather answers to these 

questions through other means.

2) EPA’s Risk Assessment is failing to assess or model physical factors that are common 

and significantly affect the risks modeled from CCR placement.

Furthermore, we note that this Human and Ecological Risk Assessment (RA)5fails to even 

assess higher risks from scenarios occurring at coal combustion waste sites that are common and 

documented in these comments. Like the ICR’s, the RA fails to even attempt to determine the 

distances of drinking water or other wells from coal ash sites instead relying on a 1988 survey of 

the distribution of residential and municipal wells around municipal solid waste landfills.6 The 

RA’s EPACMTP model and the ash disposal scenarios that were modeled did not allow EPA to 

assess risks from disposal practices that have been documented to produce the highest risks to 

people, involving the following physical inputs:

1. Disposal in impoundments that do not have an unsaturated zone beneath them;

2. Disposal in impoundments that produces a mound in the water table driving groundwater 

radially outward in all directions from the impoundment; and

3. An impoundment in which ash has been placed below the water table.

NO UNSATURATED ZONE

The RA discusses the existence of the unsaturated zone relied upon in the EPACMTP model in 

Section 3.5.2 Modeling Approach and Assumptions:

Figure 3-5 illustrates a compartmentalized surface impoundment with stratified sediment. Shown 

in the figure are the liquid compartment, the sediment compartment (with loose and consolidated 

sediments), and the unsaturated zone (with clogged and unaffected native materials). The model 

assumes that all sediment layer thicknesses remain unchanged throughout the life of the unit.

The EPACMTP surface impoundment model uses the unsaturated zone flow model to calculate 

the infiltration rate out of the bottom of the impoundment. This model is designed to simulate 

steady-state downward flow through an unsaturated (vadose) zone consisting of one or more soil 

layers. Steady-state means that the rate of flow does not change with time. In the case of flow out 

of an unlined surface impoundment, the model simulates flow through a system consisting of 

three layers: a consolidated sediment layer, a clogged soil layer, and a native soil layer.

The native unsaturated soil extends downward to the water table.7
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-79

Implicit in the contamination of shallow groundwater that has been so commonly documented 

from unlined surface impoundments is the fact that with time, there is no unsaturated zone of soil 

or other earthen material left between the bottom of the pond and the underlying groundwater. 

Therefore no attenuation of ash contaminants and no reduction in infiltration of ash leachate 

migrating through unsaturated materials are occurring. Yet the modeling in the RA assumes 

such a scenario never exists in its calculation of risks from unlined CCW impoundments.

MOUNDING ARTIFICIALLY CONSTRAINED

The RA’s modeling also artificially constrains the effects of groundwater mounding that 

commonly occurs at unlined CCW impoundments. Section 3.5.2 explains this constraint:

The modeled infiltration is governed by the depth of liquid in the impoundment and the 

following limiting factors: . . .

 Limitations on maximum infiltration rate from mounding. If the calculated 

infiltration rate exceeds the rate at which the saturated zone can transport the 

groundwater, the groundwater level will rise into the unsaturated zone. The model 

accounts for groundwater mounding when calculating the infiltration rate from the 

surface impoundment unit and, if necessary, constrains the value to ensure that the 

groundwater mound does not rise to the bottom of the surface impoundment unit.8

Just as the unsaturated zone is invariably extinguished under some portion of an unlined surface 

impoundment that is contaminating underlying groundwater, monitoring at countless unlined 

CCW impoundments and other damage sites from ash disposal demonstrates that mounding is 

often occurring at these sites. The water table has risen to and above the bottom of the ash pond 

or landfill in these scenarios. The higher head within the disposal site is driving groundwater 

radially outward from the site including in directions considered to be upgradient based on 

predisposal topographic flow assumptions. Information from monitoring and documented 

damages establishing the existence of mounding have already been submitted to EPA for sites 

such as the Gibson plant site in Indiana,9the Shawnee plant site in Kentucky, the Cardinal and 

Gavin sites in Ohio10 and many other sites. Mounding at the Gibson site’s ash ponds, examined 

further in these comments has been identified as the probable culprit for the contamination of 

private wells upriver from the site. Mounding is also evident in the radial flow outward from a 

Rush Island Plant ash pond in Missouri examined further in these comments.

DISPOSAL IN GROUNDWATER IGNORED

Perhaps the most egregious CCW disposal practice, dumping ash directly into the water table, is 

also not accounted for in the RA.11 The EPACMTP model cannot do the arithmetic necessary to 

simulate groundwater moving laterally through thousands of tons of coal ash in the bottom of an 

ash pond that was excavated directly into the sand and gravel of a shallow floodplain aquifer. 

Without such capability, EPA cannot assess the greatly reduced attenuation and sorption of CCW 

metals from the lack of any unsaturated material to interact with ash leachate. Instead the 

groundwater has become the source water, i.e., the concentrated ash pore-water. Even saturated 

material that would underlie ponds built above the water table is not available to attenuate or

sorb ash contaminants in this scenario. The infiltration rate will be far higher in such a scenario. 

The concentrations of contaminants such as arsenic reaching human receptors from this scenario 

could also be far higher than the concentrations producing the highest risks modeled in the RA. 

Mitigating arsenic risk has been a primary driver of EPA’s proposed coal ash rule. Given this 

concern and the emphasis in RCRA of preventing endangerment and harm, it is hard to 

understand why EPA persists in using a model in the RA that cannot calculate risks from the 

scenario of ash disposal below the water table.

EPA’s modelers may have assumed that nobody would be foolish enough in the electric power 

industry or in state regulatory agencies to have started this practice, much less allowed it to 

continue up to the present day. Unfortunately the evidence from EPA’s damage cases and state 

files indicates any such assumption was and still is woefully mistaken.

Neither of the states whose impoundments are examined in this comment, Indiana nor Missouri, 

has a law or regulation prohibiting the construction of an ash pond excavated into groundwater.

Because EPA did not ask utilities if their ash ponds or landfills are built below the water table in 

the May 2010 ICR Questionnaire or in any previous ICR, it is not easy to make such 

determinations from information available to the public. However, we were able to make 

approximate determinations by comparing the deepest (lowest) elevation reported for the bottom 

of ponds in responses to the May, 2010 Questionnaire to the elevation for the average static 

water level for all wells within one mile of the ten power plants in Indiana that we examined in 

this comment. Utilities managing two of these plants, Clifty Creek and Tanner Creek, redacted 

all information on the dimensions of their ash ponds from their responses to the Questionnaire.

Ponds at all of the remaining eight plants that we examined have bottom elevations that are 

below the average static water levels reported for wells within a mile of the plant.

In Missouri, ponds at three of the four power plants examined in our comments are below the 

water table. This information is based on “Detailed Site Investigations” that are required for 

those power plants to build a coal ash landfill on their property. While the utility is not required 

to report on groundwater chemistry in a DSI, the utility must submit information on groundwater 

that divulges whether ash ponds on site are in the water table. We note that answers to the 

questionnaire appear to provide bottom elevations for Missouri ash ponds that conflict with 

much of the information in the DSIs.

Placement of CCRs near or below the water table is a fundamental causal factor for the damages 

that EPA has documented from CCRs in its damage case assessments. This analysis of CCR 

ponds at plants in Indiana and Missouri suggests that placement of CCRs below the water table is 

still a fairly common practice, and that there are potentially many active CCR ponds built to 

dimensions below the water table that may operate for many years into the future. EPA must 

model the risks from this practice to understand the risks that Americans will continue to face 

from CCR disposal if EPA fails to promulgate rules that require the prompt phase out of such 

ponds under subtitle C and the removal of their contents from the water table.

There are a number of closed ash ponds at the 14 plants we examined in Indiana and Missouri. 

We did not observe a single such closed pond in the process of going through “clean closure.” 

Given the high numbers of ash ponds at these plants that appear to be below the water table, the 

failure to require removal of the ash from such ponds will leave a continual source of 

contamination in place in the sand and gravel aquifers of floodplains as groundwater continues to 

move laterally through large volumes of CCR into the indefinite future at these sites. These 

shallow aquifers are highly productive and a major resource for farming, industry and water 

supply that is crucially important to the long-term well-being of many communities. Regardless 

of whether EPA’ RA addresses the danger to these communities from large volumes of coal 

combustion residuals that are still being dumped into their water supplies, the agency’s proposed 

rule needs to assure that these communities will not be saddled into the indefinite future with 

monitoring and cleanup bills from the reckless placement of CCR below the water table.

In June 2010 EPA proposed a rule for CCRs. In that rule EPA defined CCRs as follows:

"Coal Combustion Residuals (CCRs) means fly ash, bottom ash, boiler slag, and flue gas 

desulfurization materials destined for disposal. CCRs are also known as coal combustion wastes 

(CCWs) and fossil fuel combustion (FFC) wastes, when destined for disposal (emphasis added).

To avoid the negative impacts anticipated by the Proposed CCR Rule, as summarized below and 

discussed in detail in our comments on the Proposed CCR Rule, CertainTeed continues to 

request that EPA promulgate clarifying language acknowledging that Wallboard Gypsum is not a 

CCR, and in the alternative, an explicit regulatory exemption for Wallboard Gypsum specifically 

excluding Wallboard Gypsum from the scope of any final CCR Rule.

For more than 20 years, gypsum manufacturers have successfully and safely developed 

technologies to use FGD gypsum to manufacture wallboard. Electric utilities use a multistep 

manufacturing process to produce gypsum material that is sold to make wallboard. These public 

comments refer to that gypsum material as“Wallboard Gypsum.” It is also commonly known as 

“washed gypsum,”“washed FGD gypsum,”FGD gypsum and“synthetic gypsum.” Importantly, 

Wallboard Gypsum is not fly ash, boiler slag, bottom ash, FGD sludge, or unwashed FGD 

gypsum.

Comment Excerpt: 

The Proposed ELG Rule includes an important discussion on a related rulemaking regarding 

CCRs. As discussed above, EPA is reviewing the Proposed ELG Rule and Proposed CCR Rule 

together to understand what impact the two rulemakings will have on human health and the 

environment, as well as the regulated community. As part of that coordinated review, EPA has 

suggested that the new regulatory requirements laid out in the Proposed ELG Rule may allow 

CCRs to continue to be regulated under Subtitle D of RCRA. 78 Fed. Reg. at 34442.

CertainTeed believes that regardless of the outcome of the Proposed ELG Rule, CCRs should be 

regulated under Subtitle D. As part of the comments filed by the Gypsum Association, of which 

CertainTeed is a member, the Gypsum Association provided a comprehensive overview of 

external and internal environmental, health and safety studies that repeatedly affirm the safety of 

Wallboard Gypsum. In connection with its review of and comments on the Proposed CCR Rule, 

the Gypsum Association retained ARCADIS, an environmental consulting firm, to evaluate data 

concerning Wallboard Gypsum and determine whether Wallboard Gypsum is safe and 

environmentally responsible. ARCADIS found that Wallboard Gypsum is a manufactured 

product and not a waste. Since Wallboard Gypsum is not a waste, it cannot be a RCRA 

hazardous waste.

In the absence of any risk to human health or the environment, regulation of CCRs as nonhazardous waste under Subtitle D of RCRA remains the appropriate approach. However, even if 

EPA were to conclude that CCRs are to be regulated under Subtitle D, there is an open question 

about how the Agency views Wallboard Gypsum. To avoid any regulatory confusion, and 

consistent with EPA's intent not to regulate beneficially-reused CCRs such as Wallboard 

Gypsum, CertainTeed requests that the Agency acknowledge that Wallboard Gypsum does not 

fall within the definition of a CCR. In the alternative, CertainTeed requests that Wallboard 

Gypsum be specifically exempt from regulation under 40 C.F.R. § 261.4(a). Specifically,

CertainTeed proposes that the Agency adopt the following language as it relates to Wallboard 

Gypsum:

"Wallboard grade synthetic gypsum does not fall within the definition of coal combustion 

residuals.”

In the alternative CertainTeed proposes that the Agency adopt the following language exempting 

Wallboard Gypsum from regulation under 40 C.F.R. § 261.4(a):

“The grade of Wallboard Gypsum used in the manufacture of gypsum panels is excluded from 

regulation under 40 C.F.R. § 261.4(a).

The ELG Rule Does Not Eliminate the Need for Stringent Coal Ash Disposal Rules under 

RCRA. While Options 4 and 5 of the ELG rule are critical steps to controlling the liquid 

discharges from coal-burning power plants, EPA must not stop there— the Agency must proceed 

to finalize a coal ash rule as soon as possible. The most stringent options in the proposed ELG 

rule eliminate the discharge of billions of gallons of toxic wastewater to our rivers and streams 

each year, as well eliminate the disposal of liquid waste in more than 1,000 largely unlined or 

inadequately-lined ash and sludge impoundments. While these are essential and long overdue 

steps, the rule does not begin to address many additional health and environmental threats posed 

by coal ash. Specifically, the ELG rule does not address safe closure of the thousand leaking and

potentially unstable coal ash impoundments nor does it address monitoring and cleanup of 

contaminated groundwater, control of toxic dust, siting and construction of engineered landfills 

or provision of financial assurance for toxic spills and dump closures. Federally enforceable 

minimum standards under RCRA are needed to complement the strongest ELG option, and 

together they can address the toxic pollution from the hundreds of polluting coal-burning power 

plants.

B. EPA’S PROPOSAL TO USE A GROUNDWATER INTERCEPTION MODEL THAT 

GROSSLY UNDERESTIMATES RISK TO DRINKING WATER IS ARBITRARY AND 

CAPRICIOUS AND CONTRARY TO LAW.

EPA proposed in the preamble that the facility-specific data collected by EPA’s Office of Water 

for the ELG rule could be used in EPA’s risk assessment in ways that would significantly affect 

the results of that assessment.856 Specifically, EPA noted that these data could be used to 

determine the extent to which plumes of contamination leaching from coal ash disposal units into 

groundwater are intercepted (and reduced) by surface water bodies that exist between a disposal 

unit and a down-gradient drinking water well. According to EPA, these data “would allow 

EPA to better estimate the contaminant levels that people would be expected to receive in 

drinking water, and to better model the likely environmental risks (e.g., to fish and other aquatic 

life) from such contaminants in surface waters.”857 EPA concluded that “because so many of the 

disposal units ... are located next to rivers, the results of the interception analysis could 

reasonably be expected to have a significant impact on the risk assessment results.”858

There are several significant problems with the use of the data derived from the ELG rulemaking 

and with the use of a new mathematical procedure introduced in the recent CCR NODA that 

purports to determine the impact of these nearby surface water bodies.859 EPA’s use of the data 

ignores key factors that affect migration of CCR contaminants including infiltrating leachate-soil 

interactions, the effects of water table mounding or depletion on the direction of groundwater 

flow at the local scale, aquifer heterogeneities, and the presence of actual receptors that are likely 

impacted by the CCR waste management units. Detailed comments addressing these issue were 

submitted in response to the NODA and they are attached to these comments as Appendix XII-1,

EPA must consider the complex interactions of groundwater flow, leachate development, and 

large waste deposits and examine the site-specific evidence that identifies risks and documents 

high levels of contaminants in groundwater at sites near large bodies of water, where such 

interactions have taken place. To ignore the evidence of groundwater contamination and the 

populations at risk at these sites is without rational basis and contrary to law. Blind adherence to 

a model that may describe contaminant behavior at some, but not all sites, fails to protect human 

health and the environment and ignores the voluminous record of damage contained in the CCR 

docket.

C. EPA’S USE OF CHEMICAL DATA SUBMITTED TO THE OFFICE OF WATER TO 

MODEL IMPACTS TO GROUNDWATER FROM CCR DISPOSAL UNITS IS ARBITRARY 

AND CAPRICIOUS AND WITHOUT RATIONAL BASIS, BECAUSE THE DATA ARE NOT 

REPRESENTATIVE OF LEACHATE FROM CCR LANDFILLS AND IMPOUNDMENTS.

The information in the ELG database pertaining to chemical data, while potentially relevant to 

determining the quality of water discharged directly to surface water, must not be used to revise 

the CCR risk assessment. The chemical data submitted in response to the questionnaire were not 

generated with the goal of being representative of the chemical diversity and variability of CCR 

disposal units. The reported data represent regulated effluents or monitoring points that have

been selected for purposes unrelated to determining the nature of leachate entering 

groundwater from CCR landfills and impoundments.860 These data cannot be directly compared 

with data that were acquired following the scientific method to characterize specifically the 

compositional variability and diversity of environmental releases from CCR disposal 

units. Combining the ELG’s treated and untreated leachate data with the CCR-specific leachate 

data in the risk assessment would be arbitrary and without rational basis.

Specifically, the use of the chemical data ignores the critical difference between pore water and 

leachate. There is almost never pore water collected as impoundment leachate, and 

impoundment water will almost invariably have lower concentrations of metals and other coal 

ash contaminants than pore water. The two primary reasons for the lower concentrations in 

discharged impoundment leachate are one-time and brief contact with CCR and dilution from 

precipitation and storm water runoff when the leachate is co-managed. In the case of the ELG 

chemical data, the industry responses indicate the leachate is often co-managed. Thus the 

leachate data represent low contaminant concentrations compared to the pore water data used in 

the CCR risk assessment.

In contrast, if a CCR waste disposal unit had a sub-waste leachate collection system and industry 

responders collected that leachate and analyzed it before treatment or mixing with other leachate 

or runoff, it would represent pore water within the landfill or impoundment. Without meeting 

each of these conditions, however, the sampled leachate does not represent pore water, and 

it will almost certainly be less concentrated than a pore water sample would be. There is no 

indication that any of the sampling data submitted by industry pursuant to the ELG questionnaire 

was undiluted pore water, because the questionnaire did not direct responders to analyze 

that type of sample.861 EPA did not place the schematic diagrams or photos of the sampling 

points required by the questionnaire in the record, so commenters cannot consult these 

sources. EPA, however, can and must do so.

Commenters note that any water that comes in contact with CCR is “leachate,” and while it is 

legitimate to identify the data submitted to EPA as “leachate,” it is not “pore water” and 

therefore its application to the risk assessment must be scrutinized. For purposes of 

modeling groundwater impacts in the CCR risk assessment, only pore water should be used. If 

other forms of leachate are combined with the pore water data, gross underestimation of risk will 

result. For example, EPA cannot and must not conclude that the concentrations of arsenic and 

other contaminants in leachate reported in the industry responses to the questionnaire 

are representative of pore water, particularly for surface impoundments.

Further information on the need to use the ELG chemical data for the specific purpose for which 

it was collected and its inapplicability to the CCR risk assessment is found in Appendix XII-A

and an exhibit attached to this comment letter.

860 See ELG Questionnaire, Part G, Leachate Sampling Data. “The untreated leachate samples 

must be collected directly from the leachate collection system or holding tank prior to any form 

of treatment.” “If the [unit] has multiple collection points, the untreated sample may be collected 

from a common header area, if applicable. If there is not a common header area for the [unit], the 

plant may select one of the collections points that is “representative” of the [unit] from which to 

collect the sample. If warranted . . . the plant may need to collect samples from more than one 

collection point to obtain representative samples.”

D. EPA MUST CONSIDER INCREASED RISK FROM THE SUBSTANTIAL RISE IN THE 

NUMBER OF UNLINED AND INADEQUATELY LINED SURFACE IMPOUNDMENTS 

IDENTIFIED IN THE DATA GATHERED FOR THE ELG RULE.

EPA notes in the preamble to the ELG rule that new data submitted by industry provided 

information on the location, size, and the type of waste present in hundreds of CCR 

surface impoundments that were omitted from the data sources on which EPA relied to develop 

the proposed CCR rule. The increase in the number of known surface impoundments is 

substantial; the number of CCR surface impoundments increased 50 percent from 710 to 1,070 

impoundments since 2010. EPA also noted that the newly identified impoundments were 

generally smaller than the impoundments included in the data used to support the proposed CCR 

rule. EPA, must however, look at factors beyond volume, which is not always determinative of 

the risk posed by CCR dumps.

EPA must consider a multitude of factors in addition to volume of CCR when determining risk to 

human health and the environment. According to EPA’s Office of Research and Development, 

the extent of leaching from CCR disposal units involves the following critical controlling factors: 

chemical factors, physical factors and site conditions.862 Chemical factors include 

equilibrium/kinetic control, pH, liquid-solid ration, complexation, redox, sorption and biological 

activities.863 Physical factors include particle size and rate of mass transport.864 Third, site 

conditions include flow rate of leachate, temperature, bed porosity, fill geometry, permeability 

and hydrological conditions.865 These factors, as well as the proximity of sensitive receptors, 

have great impact on the risk posed by the release of hazardous substances from CCR disposal 

units.
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-89

In addition, the Agency must also consider the presence or absence of safeguards to prevent the 

migration of hazardous contaminants. The absence of composite liners at CCR surface 

impoundments is of great concern, and the widespread lack of barriers to stop contaminant 

migration must be factored into the risk assessment.866 According to the draft risk assessment, 

only composite liners are effective in reducing the leaching of dangerous quantities of hazardous 

substances into underlying groundwater.867

This should be of great concern to EPA, because the responses to the ELG questionnaire indicate 

with certainty that at least 61 percent of all surface impoundments lack composite 

liners.868 However, the actual number of impoundments without composite lines may greatly 

exceed this number. Due to the lack of clarity of both EPA’s questionnaire and the industry 

responses (9.5 percent of responders failed to answer the question, most responders did not 

provide a complete response, and some answers were contradictory), an exact count of surface 

impoundments lacking composite liners is impossible.869 However, when one considers that a 

high-density polyethylene (HDPE) membrane is an essential component of a composite liner 

system, only 78 active surface impoundments in total (only 6.8 percent of surface 

impoundments) admitted to using a HDPE liner. The number diminishes even further when one 

considers the requirement that the HDPE liner be combined with a compacted clay liner and 

achieve minimum hydraulic conductivity. Based on these factors, the number of active surface 

impoundments meeting these criteria dwindles to less than a dozen, meaning that 99 percent of 

surface impoundments may lack protective composite liners. While the ambiguity of both the 

questionnaire and the responses prevent a precise count, it is certain that the overwhelming 

majority of operating surface impoundments lack the liners that are critical to protect human 

health and the environment. This must be taken into account in the revised risk assessment.

Lastly, EPA must amend the risk assessment to reflect the large increase in the number of CCR 

surface impoundments, which greatly increases the potential for birds, amphibians and wildlife 

to be injured by these “attractive nuisances.” CCR impoundments often create habitats attractive 

to many species of wildlife.870 Landscape features of CCR impoundments often include wooded 

edges, open herbaceous areas, and open water and can provide nesting habitat for birds 

(e.g., shrub and tree edges) as well as abundant and diverse prey populations (e.g., insects, 

amphibians and fish). However, these impoundments may attract wildlife into areas that pose 

substantial risks to their health because of the CCR contaminants in water, sediment and plants in 

and around the impoundments. For example, birds attracted to nest around coal ash settling 

basins may expose their young to contaminants by provisioning them with contaminated 

food.871 The accumulation of toxic metals, particularly selenium, in fish, birds, amphibians and 

mammals that frequent CCR impoundments can adversely affect their development, 

reproduction, and survival.872 EPA must examine the level of increased risk posed by the 

significant increase in the number of impoundments.

E. EPA MUST CONSIDER INCREASED RISK FROM THE SUBSTANTIAL RISE IN THE 

NUMBER OF UNLINED AND INADEQUATELY-LINED CCR LANDFILLS IDENTIFIED 

IN THE DATA GATHERED FOR THE ELG RULE.

As a result of industry responses to the ELG questionnaire, the number of known CCR landfills 

has also increased substantially. The number of industry-identified CCR landfills increased 30 

percent from 337 to 437 landfills.873 Most critically, the ELG data indicate that the number of 

unlined and inadequately-lined landfills must be taken into account in the CCR risk assessment. 

While industry claims that 60-62 percent of CCR landfills are lined and about 40 percent are 

unlined,874 a closer look at industry responses to the questionnaire indicates that industry has 

these figures exactly backwards.

The analysis requires a close examination of industry responses. Part F of the ELG questionnaire 

was distributed to 97 coal and petroleum coke-burning plants, which is a subset of the 504 coal 

and petroleum coke-burning plants that received the questionnaire.875 Part F contained detailed 

questions regarding the use of landfill liners. Each plant was asked first to indicate whether their 

landfills were lined and, if so, to provide information regarding the type, number and nature of 

the liner(s).876 While industry responded that more than 60 percent of the 108 landfills identified 

were “lined,” the liner descriptions tell a much different story. Because EPA did not define 

“liner,” many of the responses included materials that would not be considered to constitute a 

liner, or certainly not an adequate liner for proper CCW management. For example, layers of 

purely soil, scrubber sludge, bottom ash, and general fill were considered “liners.” Landfills that 

appear to have been placed on existing ground conditions with no amendment were also 

considered to have “liners,” including undisturbed clay, partial clay, natural clay and natural 

chinle. When one considers the absence of a constructed liner and removes these types of clearly 

inadequate liners from the dataset, the percentage of “lined” landfills falls to 39 percent, and 61 

percent of landfills can be considered “unlined,” or inadequately lined at best.

Furthermore, when one attempts to quantify the number of landfills having composite liners, 

which were identified in the risk assessment as essential to preventing migration of CCR 

contaminants, the percentage falls to about 24 percent of the total number of landfills.877 This 

estimate is conservative because the questionnaire did not ask responders to identify composite 

liners. For the purpose of this estimate, all liners employing high density polyethylene or 

PVC and having more than one liner layer were considered to have a “composite liner.”

EPA must take this critical new information into account when revising the CCR

EPA stated in the preamble to the proposed ELG rule that new data regarding landfill size from 

industry responses to the 2010 ELG survey may prompt EPA to refine the screening 

assessment of risks posed by inhalation of fugitive dust from coal ash landfills.878 We addressed 

the serious shortcomings of the screening assessment in comments submitted in response to the 

proposed CCR rule.879 The methodology employed by EPA’s 2009 screening risk assessment, 

entitled Inhalation of Fugitive Dust: A Screening Assessment of the Risks Posed by Coal 

Combustion Waste Landfills,

880 is substantively flawed and considerably underestimated risks to 

communities near coal ash landfills. Specifically, the 2009 screening risk assessment considered 

only one source of fugitive dust emissions from coal ash, i.e., wind erosion, and failed to assess 

the substantial emissions that occur during unloading and grading of the waste as well as from 

trucks traveling on the deposited waste at the landfill. Further, the 2009 screening risk 

assessment only considered risks posed by inhalation of fugitive dust particulate matter emitted 

from coal ash landfills as measured by the potential violation of national ambient air quality 

standards; it does not assess constituent-based risks, i.e., the effects of toxic trace elements 

contained in coal combustion waste nor risks posed by levels of radioactive materials found in 

the ash.

As described in more detail in the letter from Pless, attached as Appendix G, the ELG 

survey was not designed to contribute meaningful data to the risk screening assessment. EPA 

notes that the industry survey includes data on hundreds of surface impoundments that are 

generally smaller than the impoundments used to support the CCR Rule. For purposes of the 

inhalation screening risk assessment, surface impoundments must be kept separate from landfills 

because of their different operating characteristics and surface area exposed to wind erosion.881

The ELG questionnaire contains information regarding use of safeguards, in addition to liners, 

such as caps, groundwater monitoring and leachate collection systems at CCR landfill and 

surface impoundments.882 Failure to use these safeguards greatly increases the risk of release of 

hazardous constituents and/or the likelihood of remediation before toxic chemicals meet 

receptors or enter drinking water. EPA must determine the extent to which both existing and 

closed CCR disposal units are employing critical safeguards and factor this information into the 

final risk assessment. In addition, the data regarding closed units must be used in the risk 

assessment to determine the relative risk posed by legacy waste units. For example, according 

to the ELG data, while 70 percent of operating landfills have some sort of liner, 55 percent of 

closed landfills have absolutely no liner.883

2. The significant increase in the number of CCR damage cases demonstrates the validity of the 

high risk findings of the draft risk assessment, particularly as it relates to arsenic.

Data made available for the proposed ELG Rule demonstrates that the risks to human health and 

the environment from disposal of coal ash have increased throughout the United States. The 

docket for the ELG Rule included a document, entitled Final Determination of Identified Proven 

Damage and Recently Alleged Damage Cases, in which EPA confirms that there are 38 proven 

and 95 potential coal ash damage cases.884 This represents an additional 18 proven and 49 

potential coal ash damage cases than previously confirmed by EPA in its proposed 2010 CCR 

rule, nearly doubling the number of confirmed damage cases and more than doubling the number 

of potential damage cases.885 This new information should be incorporated into EPA’s draft CCR 

risk assessment and factored into EPA’s decision-making process on the CCR disposal rule in 

order to properly account for the increased risks of current disposal practices.

Surprisingly, the preamble to the ELG Rule did not mention the 68 new damage cases, although 

EPA did indicate that new data relating to CCR were available in the docket. While ignoring the 

greater evidence of damage, EPA specifically noted that the new information on size and 

management practices at coal ash disposal units – should serve to “lower the CCR rule risk 

assessment results.”886 EPA, however, must consider the evidence in the record, which 

demonstrates that damage has in fact occurred at far more sites than previously acknowledged. 

Such evidence of damage provides strong support for a RCRA Subtitle C disposal rule.

EPA should use all of the new data made available by the ELG docket regarding potential risks 

to human health and the environment from coal ash disposal sites to prepare both its ELG and 

CCR rule. The Agency must not arbitrarily and capriciously ignore evidence of real world harm 

at dozens of new sites nationwide.

As described in comments submitted to EPA pursuant to the CCR NODA,887 and further 

discussed below, EPA’s impoundment assessment reports,888 which assessed the 

structural integrity of more than 500 CCR impoundments, revealed significant problems at a 

large number of potentially dangerous dams. The assessments documented a high level of risk 

posed by numerous high and significant hazard dams that either were found not to have factors 

of safety889 that met federal standards or had not conducted sufficient analyses to determine such 

factors. Of the 516 assessments completed, only 41 percent of the dams (214 dams) were rated 

“satisfactory,” and 59 percent were rated “poor” or “fair.” In fact, 80 high and significant hazard 

dams were found to be in poor condition.890 In addition, the much more detailed assessments 

conducted on the 24 TVA dams, which involved in-depth geotechnical analysis of each dam, 

revealed that half of the dams were in poor condition, in danger of failure and required repair to 

ensure structural stability. If equivalent analyses were performed on each of the 516 dams 

inspected by EPA, it is likely that many more dams would have been found in conditions similar 

to the TVA dams. These comments also incorporate by reference the comments by former 

MHSA Director, Jack Spadaro, submitted by Commenters as an exhibit to this letter.

Comment Excerpt: 

EPA’s “List of Coal Plant and Closest Receiving Water” purports to link each coal plant with the 

closest receiving water body. EPA’s list, however, does not always include all receiving waters 

associated with a coal plant. EPA states “EPA created a list linking the location of each coal 

plant with the closest receiving water body for evaluating surface water risks as well as human 

health risks.”891 Our review of a handful of National Pollutant Discharge Elimination 

System (NPDES) permits and applications reveal that EPA’s list does not include all receiving 

waters for some plants.892

We reviewed 36 NPDES permits and found that EPA did not list all receiving waters for 13 of 

these plants.893 For example, EPA’s list states that the Ohio River is the sole receiving water for 

the W. H. Zimmer plant. However, the permit states that the plant discharges into the Ohio 

River, Maple Creek, and Little Indian Creek.894 A list of the 36 plants reviewed and additional 

receiving waters for the 13 plants is submitted as an exhibit to this comment letter.

These omissions are significant and would likely impact the risk assessment by erroneously 

lowering risk levels. Large rivers have more capacity to dilute toxic pollution from coal 

combustion waste impoundments and landfills. Toxic pollution in small streams and creeks will 

result in higher concentrations of selenium, cadmium, and other pollutants that are toxic to 

aquatic life in minute concentrations. In addition, humans recreating in and around these smaller 

water bodies will also face a greater risk of adverse health effects from exposure to higher 

concentrations of coal combustion waste pollution. In order to evaluate the risks of 

coal combustion waste disposal in a meaningful way, EPA must account for surface water 

loadings in all receiving waters. Thus, EPA should review the NPDES permit and application 

for each coal plant to ensure that all receiving water bodies are identified and taken into account 

in the risk assessment.

XVI. THE ELG RULE DOES NOT ELIMINATE THE NEED FOR STRINGENT CCR 

DISPOSAL RULES UNDER RCRA

While Options 4 and 5 of the ELG rule are critical steps to controlling the liquid discharges from 

coal-burning power plants, EPA must not stop there—the Agency must proceed to finalize a coal 

ash rule as soon as possible. The most stringent options in the proposed ELG rule require 

conversion to dry handling of fly ash and bottom ash and the treatment of FGD wastewater, and 

thus would eliminate the discharge of billions of gallons of toxic wastewater to our rivers and 

streams each year, as well eliminate the disposal of additional liquid waste in more than 1,000 

largely unlined or inadequately-lined ash and sludge impoundments. While these are 

essential and long overdue steps toward protecting the health and the environment of 

communities living downstream of coal plants, the rule does not begin to address many 

additional health and environmental threats posed by coal ash. Specifically, the ELG rule does 

not address safe closure of the thousand leaking and potentially unstable coal ash impoundments 

nor does it address monitoring and cleanup of contaminated groundwater, control of toxic dust, 

siting and construction of engineered landfills or maintenance of financial assurance for toxic 

spills and dump closures. Federally enforceable minimum standards under RCRA are needed to 

complement the strongest ELG option, and together they can address the toxic pollution from the 

hundreds of polluting coal-burning power plants.

Assuming, as discussed in Section X, that EPA addresses structural stability requirements for

CCR impoundments under specific, timely and enforceable BMPs, the following critical gaps 

still need to be addressed by an enforceable federal coal rule under RCRA as soon as possible.

Comment Excerpt: 

If EPA fails to finalize Options 4 or 5 and to address legacy wastewater, releases of hazardous 

substances from CCR surface impoundments will continue to damage groundwater and surface 

water and adversely impact human health and the environment, absent strong RCRA regulations. 

Continued operation of CCR impoundments requires stringent ground water monitoring and 

corrective action standards when contaminants are detected. Furthermore, the construction of 

additional new impoundments is likely to continue under EPA’s weaker options, and currently 

there are no federal CCR standards in place to require adequate design and maintenance. The 

widespread absence of adequate state regulations governing CCR disposal 

makes the establishment of minimum federal standards absolutely essential to protection of 

health and the environment.895

programs. See Comments of Earthjustice et al. to U.S. Environmental Protection Agency (“U.S.

It is well established that pH conditions exert strong control on the release, fate, and transport of 

contaminants in the environment (Stumm and Morgan, 1996). This dependence and control is 

illustrated in Figure 1 for arsenic and selenium (EPA, 2006; EPA, 2012).
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

Leachate samples obtained from coal combustion waste (CCW) materials show a very large 

range of pH values, from less than 3 to more than 12 SU, depending on the type of waste or 

waste management unit (EPA, 2006; EPA, 2009).

A review of pH data from the EPA studies that are relied upon in the 2010 risk assessment (EPA, 

2010) and from the Questionnaire results (EPA, 2013) lead to the following observations and 

conclusions:

1. The available pH data for leachate from CCW materials in landfills and impoundments 

indicate that these two modes of disposal result in different leachate pH distributions. 

This is illustrated in Figure 2 using the data from the input files of the 2010 risk 

assessment (n = 89 for landfills, 14 for impoundments). The two leachate pH 

distributions are statistically different from one another (p < 0.05; t-test).

2. The pH data for CCW landfills and impoundments reported in the Questionnaire 

similarly show that the pH distributions are different for these two modes of disposal. 

This is illustrated in Figure 3 using data from the Questionnaire (n = 211 for landfills, 69 

for impoundments). The two leachate pH distributions are statistically different from one 

another (p < 0.05; t-test).

3. The pH distributions for CCW landfills and impoundments from the Questionnaire 

results are substantially different from the distributions from various studies relied upon 

in the 2010 risk assessment. This is illustrated in Figure 4. The leachate pH distributions 

are statistically different from one another (p < 0.05; t-test).

The Questionnaire results report pH conditions for CCW landfills and impoundments that are 

overwhelmingly in the neutral range (pH 6 to 8 range). In this pH range, the solubility and 

mobility of arsenic, selenium, and most metals are low compared to pH values outside of the 

neutral range (see, for example, Figure 1). The leachate pH values reported in the Questionnaire 

are for samples collected from a variety of drains, outfalls, seeps and drainage areas.1 Samples 

collected from these locations most likely represent mixtures of leachate and other drainage and 

precipitation water rather than CCW leachate end-members.

The risk assessment model requires end-member leachate compositions as input. In the model, 

the effect of attenuation processes is applied starting with the end-member 

compositions and carried forward as the leachate transports and reacts in the 

environment. Using compositions that do not represent leachate end-member compositions as 

input to the model is therefore inappropriate for the risk assessment. Samples that represent 

CCW leachate end-member compositions cannot be identified based on the information provided 

in the Questionnaire. The Questionnaire results can therefore not be used as end-member input in 

the risk assessment model.

These observations and conclusions are important and cannot be ignored. First, the data indicate 

that pH distributions are different for CCW landfills and impoundments, and therefore different 

distributions should be used in the risk assessment. Second and most important, the data indicate 

that the Questionnaire results are not representative of the pH conditions in CCW landfills and 

impoundments, and therefore, the Questionnaire data should not be relied upon to represent pH 

conditions in CCW landfills and impoundments. This latest conclusion is supported by:
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

 The pH values reported in the Questionnaire are inconsistent with results obtained by 

several scientific studies that were conducted specifically to characterize and represent 

CCW landfills and impoundments leachate compositions. These studies include EPA 

2006, EPA 2009, and other data sources reviewed and compiled by the EPA for the 2010 

risk assessment. The pH distributions from these studies (as used in the 2010 risk 

assessment input files), the EPA’s large-scale compilation of landfill leachate pH (EPA, 

2009; Section 2.5.2), laboratory pH from fly ash samples (EPA, 2009, Appendix I)2, and 

the Questionnaire results are illustrated in Figure 5. The figure illustration supports the 

conclusion that the Questionnaire results are different and not representative of the endmember leachate compositions from CCW landfills and impoundments. The 

Questionnaire pH distributions for untreated water samples from CCW landfills and 

impoundments have median pH values that are neutral (7.45 and 6.66, respectively). The 

corresponding median values from the scientific studies used in the 2010 risk assessment 

are much more basic (10.10 and 9.05, respectively). These pH distributions are 

summarized in Table 1.

 The pH and chemical results reported in the Questionnaire were not generated with the 

goal of being representative of the chemical diversity and variability of the CCW waste 

management units and the leachate composition generated by these units. The reported 

data most often represent regulated effluents or monitoring points that have been selected 

for various purposes (e.g. NPDES discharge points, post treatment leachate; see footnote 

1).

 The nature of the samples reported as leachate in the Questionnaire and their pH values 

have not been verified.

 In the Questionnaire the reported pH values represent less than 4% of the number of the 

reported CCW impoundments.3

The conclusion that the pH values reported in the Questionnaire are not representative of 

leachate from CCW landfills and impoundments is supported by several scientific studies, as 

discussed above. This conclusion implies that the chemical results reported in the Questionnaire 

are also not representative of the leachate end-members from CCW landfills and impoundments. 

This is a direct consequence of the control pH exerts on dissolved composition and on the 

mobility of chemicals in the environment. This is well established in the peer-reviewed literature 

(see for example Stumm and Morgan, 1996) and illustrated in Figure 1 for arsenic and selenium.

Arsenic concentrations reported for CCW leachate in the Questionnaire are lower than the 

concentrations used in the 2010 risk assessment (for example, the arsenic median concentration 

in the Questionnaire is about 20 times lower than in the 2010 risk assessment). This is simply a 

consequence of the fact that the values reported in the Questionnaire are not representative of 

leachate from CCW landfills and impoundments. Similarly to arsenic, concentration differences 

between the Questionnaire results and the scientific studies relied upon in the 2010 risk 

assessment are best explained by the lack of representativeness of the Questionnaire results. 

Concluding otherwise would rank scientific studies behind self-reporting by an interested party, 

and this without even the benefit of verification of the self-reporting data and information

In summary, the pH values reported in the Questionnaire are not representative of CCW landfill 

and impoundment leachate composition and should therefore not be relied upon as such. The 
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

Questionnaire results show a narrow neutral pH distribution for water samples from CCW 

landfills and impoundments; these values are inconsistent with the much broader distribution 

reported for leachate end-member compositions in the scientific studies. Under the neutral pH 

range reported by the Questionnaire, the solubility and mobility of arsenic, selenium and most 

metals is typically low (see for example Figure 1 and Stumm and Morgan, 1996). Outside of the 

neutral range, leachate concentrations are typically higher, often by orders of magnitudes. 

Combining the Questionnaire results for pH and contaminant concentrations with data from the 

scientific studies would bias the pH distributions toward the neutral range and decrease the 

concentrations of contaminants in the risk assessment model input for leachate end-member 

compositions. Doing so would be inappropriate for the purposes of the risk assessment.

1 In the Questionnaire responses, leachate samples were typically not provided with a detailed 

description of the sample location. However, some of the descriptions provided include: “ditch 

along road where seepage collects”,

2 Data based on testing conducted on 40 fly ash samples from coal-burning facilities. Leaching 

of these samples produced pH values ranging from 3.92 to 12.24 with a median of 10.30 (EPA, 

2009). The distribution of these laboratory pH values is similar to the risk assessment surface 

impoundment data on the acidic end of the distribution and similar to the landfill data on the 

basic end. This data set is also different from both the landfill and surface impoundment data 

reported in the Questionnaire (p<0.05; t-test).

utility facilities, only 54 have associated pH data.

Comment Excerpt: 

Per your request, I have assessed the statement made by the U.S. Environmental Protection 

Agency (“EPA”) in the preamble to the proposed rule Effluent Limitations Guidelines and 

Standards for the Steam Electric Power Generating Point Source Category (“ELG Rule”) to the 

effect that new data regarding landfill size from a 2010 industry survey of coal- and petroleum 

coal-fired power plants may prompt EPA to refine the screening assessment of risks posed by 

inhalation of fugitive dust from coal combustion waste landfills it prepared for the proposed rule 

Disposal of Coal Combustion Residuals from Electric Utilities Coal Combustion Residuals 

(“CCR Rule”).1 My comments below rely and expand upon my previously prepared comments 

on the screening risk assessment.2

First, I would like to reiterate that the methodology employed by EPA’s 2009 screening risk 

assessment, entitled Inhalation of Fugitive Dust: A Screening Assessment of the Risks Posed by 

Coal Combustion Waste Landfills3, is substantively flawed and considerably underestimates risks 

to receptors. Specifically, the 2009 screening risk assessment considers only one source of 

fugitive dust emissions from coal combustion waste, i.e., wind erosion, and fails to assess the 

substantial emissions that occur during unloading and grading of the waste as well as from trucks 

traveling on the deposited waste at the landfill. Further, the 2009 screening risk assessment only 

considers risks posed by inhalation of fugitive dust particulate matter emitted from coal 

combustion waste landfills as measured by the potential violation of national ambient air quality 

standards; it does not assess constituent-based risks, i.e., the effects of toxic trace elements 

contained in coal combustion waste nor does it assess risks posed by radioactive materials found 

in coal combustion wastes or potential hydrogen sulfide release. In addition, the screening risk 

assessment suffers from a number of methodological errors and improper assumptions, which I 

discussed in my previous letter.

Inasmuch as EPA’s previous risk estimates for inhalation of fugitive dust particulate emissions 

caused by wind erosion may be affected by the new data from the 2010 industry survey 

regarding landfill size, I note the following:

1. EPA’s screening risk assessment assumes for purposes of estimating controlled emissions that 

the area of a landfill that is operated in any given year can be calculated as its total surface area 

divided by an estimated 40-year operating life.4 This simplistic assumption is erroneous and 

underestimates the active area of landfills subject to wind erosion:
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-108

- The assumption that a landfill is operated consistently over its lifetime such that each year only 

a fraction of the total landfill area is active is not consistent with actual operating practices. 

Landfills for coal combustion waste are built up in height over time (see photographs below) 

and, at the end of their operating life, can be several hundred feet tall. For example, a proposed 

new landfill for the Prairie State Generating Company in Illinois would cover 750 acres and 

would be 290 feet tall;5data from EPA’s 2010 industry survey indicate that landfills can be up to 

2040 feet high.6 Thus, the active landfill area may be operated for many years until the final 

height is reached. Especially at smaller landfills, the active face can extend over the entire 

landfill during its entire operating life. Thus, the screening risk assessment’s assumption of 

consistent operation with a fraction of the landfill active each year is improper and not 

conservative. Instead, for purposes of estimating emissions and calculating risk, the screening 

assessment should conservatively assume that the entire landfill area is operated on unless more 

specific information about the active face is available from surveys.
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-109

- Even if the screening risk assessment’s methodology for calculating the area of a landfill that is 

operated in a given year had merit, its assumption of a uniform 40-year operating life for all 

landfills is not supported. The estimated 40-year operating life is taken from EPA’s 1998 

Technical Background Document for the Supplemental Report to Congress on Remaining Fossil 

Fuel Combustion Wastes: Ground-Water Pathway Human Health Risk Assessment. This 

document assumes 40 years of waste deposition at coal combustion residue landfills7for 

purposes of modeling human exposure to groundwater contaminated by the release of leachate 

from coal combustion waste landfills; therefore, the assumption was intentionally conservative. 

Relying on this conservatively high assumption to estimate the area in use at a landfill per year 

has the opposite effect in that it results in a small, i.e., not as conservative, active area. In reality, 

the operating life of landfills is highly variable and dependent on several factors external to the 

landfill including generation and dispatch of the associated power plant, installation of pollution 

control equipment that may result in additional waste generation such as scrubbers, etc. in fact, 

EPA’s 2010 industry survey demonstrates the enormous variability in the number of years 

landfills are operated. For example, landfills at Plants No. 1 and 1020 were retired after only 7 

years of operation; at Plant No. 103, the landfill is projected to be retired after 20 years; and at 

Plant No. 70, the landfill is projected to be closed after 63 years.8 Thus, the assumption of a 

uniform operating life for the entire universe of landfills considered in the screening risk 

assessment (50th, 60th, 70th, 80th, and 90th percentile of landfill areas) is not realistic and 

introduces substantial errors when calculating the active acreage.
Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category:

EPA’s Response to Public Comments

10-110

- What’s more, the screening risk assessment only considers the 50th through 90th percentiles of 

size and 10th through 50th percentiles of distance to the nearest receptors and excludes the 

maximum size and minimum distance to the nearest receptor as "too conservative to be 

considered reasonable."9 To put this in perspective, the 90th percentile of landfill sizes used in 

the screening assessment is less than 300 acres, the maximum is 900 acres, more than three times 

larger. The reality is that this 900-acre landfill exists, and without appropriate controls, results in 

much higher concentrations of PM10 at the 10th percentile distance to the nearest receptor than 

modeled by the screening risk assessment based on a 90th percentile acreage.

- The screening risk assessment carries the above erroneous assumptions into its estimates of 

controlled emissions from landfills of various sizes (50th, 60th, 70th, 80th, and 90th percentile). 

The screening risk assessment further compounds these errors by assuming that the uncontrolled 

area at a landfill, i.e., the area that is in use, over a month, week, and day can be calculated by 

dividing the annual area by 12 months/year, 52 weeks/year, and 365 days/year, respectively. This 

is entirely unrealistic as the screening risk assessment essentially assumes 100 percent control of 

fugitive dust on all areas on which coal waste is not deposited during a given time period. While 

100 percent control of fugitive dust can be achieved at close of a landfill, or a section of a 

landfill, by installation of a permanent soil cover and revegetation, this is not the case for 

measures that are employed on a short-term basis such as watering, chemical dust suppressants, 

or geosynthetic tarps, etc. Such measures, while effective to control fugitive dust to some extent, 

do not result in 100 percent control. Therefore, the screening risk assessment underestimates 

controlled emissions and, consequently, concentrations of particulate matter in air.

2. EPA notes that the 2010 industry survey includes data on hundreds of surface impoundments 

that are generally smaller than the impoundments used to support the CCR Rule. EPA also notes 

that “reliance on [these] data ... may have the potential to lower the CCR rule risk assessment 

results by as much as an order of magnitude.”10 It is unclear whether the latter statement refers to 

the inhalation screening risk assessment or the 2009 Human and Ecological Risk Assessment of 

Coal Combustion Wastes which addresses risks via the groundwater pathway. For purposes of 

the inhalation screening risk assessment, surface impoundments must be kept separate from 

landfills because of their different operating characteristics and surface area exposed to wind 

erosion.11 Thus, the existence of numerous smaller surface impoundments should not affect the 

inhalation screening risk assessment from landfills.

Finally, EPA should take care not to solely rely on the results from the screening risk assessment 

in developing its recommendations for best 1nanagement practices to control fugitive dust at coal 

combustion waste landfills. Even if all methodological errors discussed above were corrected, 

the screening risk assessment still only provides an indication of whether ambient air quality 

standards for particulate matter may be violated; it is not a probabilistic risk assessment and does 

not estimate the inhalation risk due to the constituents of the coal ash. Instead of solely relying 

on the screening risk assessment, which relies on generic equations that were not developed for 

estimating emission factors from coal combustion waste landfills, EPA should collect monitoring 

data to test its theoretical assumptions. The reality is that there are numerous complaints of 

substantial visible dust clouds emanating frotn coal combustion waste landfills and settling on 

nearby communities. Furthermore, EPA may not assume that "inactive" or "closed" landfills are 

sufficiently stabilized to achieve 100 percent control.

Comment Excerpt: 

Harmonization of the final ELG and CCR rules

As EPA recognizes in the proposed steam electric ELG rule, the final steam ELG and CCR rules 

will regulate or affect the same unit and/or activity. KCP&L appreciates EPA’s request for 

comment on its views for how to harmonize these two regulations. As explained in more detail 

in USWAG comments, KCP&L supports that harmonization of the two rules requires:

 Selection of the Subtitle D Prime option in the final CCR rule to enable CCR 

impoundments, that meet applicable groundwater monitoring and corrective action 

requirements, to remain operational and to continue to manage and receive specified 

wastewaters as contemplated under the steam electric ELGs proposal;

 Modification of the proposed Subtitle D Prime option to ensure application of only 

specified location restrictions to existing CCR surface impoundments to prevent the 

premature closure of such impoundments and to enable the impoundments to remain 

operational and to continue to manage and receive specified wastewaters as contemplated 

under the steam electric ELG Proposal;

 Modification of the proposed Subtitle D option to eliminate the requirement that CCR 

units automatically commence closure upon the cessation of the receipt of CCR in order 

to prevent the premature closure of such units under the final CCR rule;

 Ensuring that any CCR rule implementation and corresponding compliance obligations 

for surface impoundment modifications and/or closure not be triggered until a reasonable 

period of time after the applicable ELG requirements are clearly established for a 

particular facility in its revised NDPES permit; and

 Developing a mechanism to allow for State implementation of the Subtitle D option – as 

opposed to a self-implementing regime – in circumstances where a State is able to 

demonstrate to EPA that its CCR regulations are no less stringent than the final Subtitle 

D controls.

I urge the EPA to adopt the Subtitle C option under their proposed national standards for coal 

ash. I feel this is needed to protect human health and the environment. I believe that proper and 

safe waste disposal is a cost of doing any business.

Fly ash is a very toxic waste and should not be exempted from RCRA hazardous waste 

regulation, and should be treated according to it's toxic characteristics.

Comment Excerpt: 

In addition, effective harmonization of the ELG and CCR rules requires that the Subtitle D Prime 

option be selected by EPA for a final CCR rule. The Subtitle D Prime option is the only option in 

the CCR proposed rule that would provide the possibility that CCR impoundments that are in 

compliance with the applicable groundwater protection standards can continue operation. The 

Subtitle D prime option would be consistent with the structure of the ELG Proposal, which 

includes the continued practice of managing bottom ash, fly ash, CCR leachate, and flue gas 

mercury wastewaters in impoundments that comply with existing BPT requirements.

If the Subtitle D Prime option is not acceptable to EPA, then EPA should at least remove the 

CCR rule Subtitle D mandatory synthetic liner retrofit- or-close requirements for existing 

impoundments that are complying with groundwater standards. Installing liners in 

impoundments is very expensive and synthetic liner requirements could force the closure of 

impoundments that manage CCRs. Many of these impoundments are also part of the plant 

wastewater treatment system for other items such as low volume wastewaters. Forced closure of

these impoundments would be counter to the continued wastewater treatment function that the 

ELG proposal rule includes for surface impoundments.
