Re:

Comments of the National Mining Association on Supplemental Finding That It Is

Appropriate and Necessary To Regulate Hazardous Air Pollutants From Coaland Oil-Fired Electric Utility Steam Generating Units, 80 Fed. Reg. 75,025 (Dec.

1, 2015)

Dear Dr. Hudson:

The National Mining Association (NMA)1 submits these comments in response to

the proposed supplemental finding that it is appropriate and necessary to regulate

hazardous air pollutants (HAPs) from coal and oil-fired electric utility steam generating

units (EGUs), 80 Fed. Reg. 75,025 (Dec. 1, 2015). In addition to submitting these

comments NMA incorporates by reference the comments of the Utility Air Regulatory

Group of which NMA is a member.

NMA urges EPA to rescind and re-propose its “appropriate and necessary”

finding for electric generating units. EPA’s proposed finding is based on an arbitrarily

limited view of the information the agency should examine in assessing the costs and

benefits of regulation. EPA seems more interested in quickly reaffirming the flawed

appropriate and necessary finding it made when it issued the MATS rule rather than

conducting the type of searching analysis the Supreme Court called for in Michigan v.

EPA, 135 S. Ct. 2699 (2015), where the Court directed the agency to “consider costincluding, and most importantly, cost of compliance before deciding whether regulation

is appropriate and necessary.” (Emphasis added.) Despite this rebuke from the Court,

NMA’s membership includes the producers, transporters and consumers of coal. Our member

companies mines over 75 percent of the coal produced annually from operations located in 26 states.

Most of the coal produced by NMA members is used by coal-fired EGUs subject to this rulemaking.

our analysis of the Supplemental Finding demonstrates that it, like the agency’s prior

determination, is wrong in reaching the conclusion that it is appropriate and necessary

to regulate HAP emissions from EGUs.2

1.

EPA has completely failed to consider the effect of its rule on coal.

Four years after MATS was issued, with the damage the rule caused in the coal

industry all but complete, EPA maintains its preposterous view reached in the MATS

Regulatory Impact Analysis (RIA) that the rule will have little effect on coal. EPA has no

new analysis to support this assertion as no such analysis can be constructed. It simply

proposes to limit its consideration of costs to the information it included in the RIA,

including the RIA forecast that the rule would result in the retirement of less than 5 GW

of coal capacity.3 By limiting its cost consideration in this fashion, the agency believes it

can erase the actual experience of the last four years and the hardship the agency has

wrought on our nation’s coal communities and ratepayers who were previously the

beneficiaries of affordable, reliable coal-based electricity.

As numerous commenters, including NMA, told EPA during the MATS

rulemaking, the rule would cause a wave of coal unit retirements. Unfortunately, events

have confirmed the accuracy of these forecasts and disproved EPA’s. Between 2012

when the rule went into effect and 2016 when the rule’s compliance period ends, almost

60 GW of coal capacity will have retired, including units that have already retired or, for

2016, have announced their retirement.

Prior to the final MATS rule, total retirements of coal-fired capacity for the

previous 11 years were just 9,745 MW, 3.1 percent of the nation’s existing coal-fired

capacity. Because of MATS, power companies retired more capacity than in all of those

years combined—10,308 MW—in 2012 alone.

Shortly after MATS was published, the Energy Information Administration (“EIA”)

recognized that this rule would contribute to a wave of retirements of coal-fired power

plants. EIA published an article in July 2012 reporting the surge of planned retirements,

which would peak in 2015, the year the initial MATS compliance period ended. This is

described graphically in the chart shown below.

Planned Retirement of Coal-Fired Generators, 2012 (MW)5

In public statements and in litigation EPA has blamed the decline in natural gas

prices for the coal unit retirements. Natural gas prices have certainly affected the

amount of actual coal generation, but low natural gas prices did not lead to the plant

retirements. While natural gas prices did fall in 2012 from 2011, the decline was not to

unusually low levels. Gas prices in 2012 were still higher than the average price of

natural gas throughout the 1990’s, as shown below. However, coal plants did not retire

in any significant quantities throughout that decade of low gas prices. The coal industry

is familiar with and has previously experienced the impact of cyclical, non-sustainable

low natural gas prices. The massive retirement of coal plants began in 2012, coinciding

with the MATS rule, not the decline in gas prices. Natural gas prices recovered in 2013

and 2014, yet coal plants continued to retire in these years also.

EPA’s reliance on its stark under-prediction of the number of retirements as a

result of MATS taints every aspect of EPA’s new appropriate and necessary finding.

Having understated the retirements in the RIA, that document also understates the

overall compliance costs of the rule, the resulting impact to electric ratepayers, the

amount of coal production that would be lost, the number of miners that would be laid

off, and the impacts to coal communities and coal states that would ensue. Forty

thousand coal miners have lost their jobs since 2012. These layoffs have occurred in

some of the poorest areas of the country, where coal-mining provides some of the

highest-paying jobs. Whole communities and a number of states are dependent on the

revenue the coal industry brings.

NMA and others warned EPA, in comments on the MATS rulemaking, of the chain

of devastation the rule would create, but EPA chose to discount those warnings. In light

of subsequent events, it is completely arbitrary for EPA to continue to pretend that the

rule has had little impact on coal.

2.

EPA Has Not Explained Why It Ignores the Actual Retirements Caused by

the Rule.

EPA offers no explanation for ignoring the actual number of retirements the rule

caused. Instead, EPA simply says, without elaboration, that it has chosen to restrict its

examination of cost impacts to the information in the RIA because doing so is

“reasonable.”7 It cannot be reasonable, however, to continue relying on cost information

that has demonstrably been proven wrong time-and-time again.

The closest EPA comes to an explanation for relying on incorrect data in the RIA

is the assertion that the public had an opportunity to comment on that information and

EPA responded to those comments.8 In the first place, it is not true that EPA conducted

notice-and-comment rulemaking on whether regulation of EGU HAP emissions is

justified in light of the regulatory costs. During the rulemaking and throughout the

litigation, EPA’s firm position was that cost information played no role in its appropriate

and necessary finding. As a consequence of this view, the agency’s main response to

the cost information proffered by NMA and others was that such information was

irrelevant.9 At no point did EPA ever examine the cost information submitted by

commenters in light of the ultimate question of whether it was appropriate and

necessary to regulate.

More fundamentally, even if EPA had fully considered the cost information

submitted in the record that would not justify EPA’s failure to rely on information from

the RIA that has proved to be faulty. The Supreme Court required EPA to make a de

novo appropriate and necessary determination that, for the first time, considers costs

and benefits. That determination must be based on cost information that is reliable and

accurate. EPA has no excuse for not considering costs associated with the large

number of retirements that the rule caused. It must redo its entire RIA cost analysis in

light of that information.

3.

EPA must accept new evidence on the purported benefits of the rule and

reconsider the evidence already submitted as to the lack of benefits

EPA states that it is not accepting comments on its finding that “mercury and

other HAP emissions are hazardous to public health and the environment.” EPA says

the public has already commented on this finding and that the agency has already

responded to all significant comments.10

As discussed above, however, because EPA is making a de novo appropriate

and necessary finding, EPA cannot exclude relevant evidence. EPA must at least

reconsider the evidence it relied on in its previous finding in determining now whether

the cost of regulation is justified by the benefits. Because EPA did not weigh costs and

benefits in its prior appropriate and necessary finding, it was of the opinion that virtually

any evidence of a risk to health or the environment would justify a decision that

regulation was appropriate and necessary. It is now EPA’s task to judge for the first time

whether the benefits it relies on are significant enough to justify the costs. This applies

to asserted impacts of all HAP emissions, but applies most critically to the asserted

impacts of acid gas emissions, as more fully discussed below.

4.

EPA Cannot Mask the Impacts of the Rule by Spreading those Impacts

Over the Entire Power Sector.

In an attempt to make the $9.6 billion annual cost of the rule seem small, EPA

compares the MATS costs with total utility industry costs.11 In EPA’s view:

x

The $9.6 billion annual cost of the rule is only a small fraction of the total annual

industry-wide dollar value of electricity sales;

x

The annual capital expenditures to comply with MATS are again only a small

fraction of all utility industry annual capital expenditures;

x

The impact of the rule on the average national electricity rate are small;

x

EPA’s estimate of 4.7 GW of retirements represents only a minimal amount of

total electric generating capacity: “This analysis indicates that the vast majority of

the generation capacity in the power sector directly affected by the requirements

of MATS would be able to absorb the anticipated compliance costs and remain

operational.”

These comparisons of MATS costs with national-level costs are meaningless.

First, as noted, they are based on EPA’s fundamentally flawed RIA that far understated

the number of coal unit retirements and thus underestimates the cost of the rule.

Additionally, national level figures are of little use in assessing the cost of MATS

in the real world. For instance, no one pays an average national electricity rate; electric

consumers pay the rate charged by their local utility which in turn reflects that utility’s

costs.

As EPA is aware, coal-fired generation is predominately confined to the middle

and southeastern parts of the country. The major population centers of California, the

Pacific Northwest, New York, New Jersey, New England and peninsular Florida use

very little or no coal generation. Obviously, the rule would not be expected to have and

has not had much impact in those areas. Spreading the cost of the rule over the large

populations served by utilities in these states therefore masks the impact the rule has

on other states.

Equally as obvious, the rule can be expected to have major impacts in coaldependent states. Information submitted to EPA during the MATS rulemaking showed

the possibility of more than 20 percent rate impacts regionally. For instance, heavy

manufacturing and coal-dependent states like Ohio can expect prices to rise by

approximately 23 percent.12 Moreover, as the economy recovers and electricity demand

increases the tightening of electric generation supplies resulting from the rule will

inevitably force electric rates to rise.

EPA seems to recognize that the rule will have disproportionately high effects in

coal-dependent regions, but dismisses those impacts with the statement that rates in

these areas are lower than the national average.13 The implication seems to be that

EPA is justified in pursuing policies that raise electric rates in these areas because

people can afford the increases. It is not EPA’s job, however, to impose the energy

policies of the coastal states—and the resulting high energy prices—on the rest of the

country. In any event, the middle of the country on average has lower incomes than the

coastal states and is therefore not in a position to absorb the higher costs. As NMA has

repeatedly told EPA in comments, high energy prices produce their own set of negative

health and welfare impacts, none of which are accounted for in EPA’s new appropriate

and necessary finding.

EPA’s focus on the rule’s national-level utility industry impacts also fails to

address the specific impacts the rule will have on coal production, coal employment and

coal communities. These impacts are clearly relevant to an analysis of the rule’s costs.

5.

EPA Must Separately Address Whether the Cost of Acid Gas Regulation Is

Justified by the Benefit.

Another topic EPA tries to declare off limits is whether EPA could decide it is not

appropriate and necessary to regulate one HAP if it is appropriate and necessary to

regulate any other HAP. EPA’s view is that this outcome is foreclosed by the court of

appeals’ decision in White Stallion Energy Ctr., LLC v. EPA, 748 F.3d 1222, 1233 (D.C.

Cir. 2014) and by the terms of the issue the Supreme Court accepted for review in

Michigan v. EPA, 135 S. Ct. 2699 (2015).

EPA is incorrect. White Stallion determined only that, as a matter of Chevron

step two deference, “EPA's conclusion that it may regulate all HAP emissions from

EGUs must be upheld,” even if it is not appropriate and necessary to regulate one

particular EGU HAP emissions. White Stallion, 748 F. 3d at 1245 (bold added, italics in

original). This EPA exercise of discretion may have been, as the White Stallion court

found; reasonable in light of the court’s finding that costs are irrelevant in the

appropriate and necessary finding. However, given the Supreme Court’s ruling that

costs are relevant, it is now unreasonable for EPA to neglect, on a pollutant-by-pollutant

basis, whether regulation may be inappropriate and unnecessary given an extreme

mismatch of costs and benefits.

Moreover, the relative costs and benefits of regulating each particular EGU HAP

emission remains relevant even if EPA is required to regulate all EGU HAP emissions

on a finding that it is appropriate and necessary to regulate one particular such

emission. In considering whether it is appropriate and necessary to regulate all EGU

HAP emissions, certainly one relevant factor would be that regulating one HAP would

impose extraordinarily high costs for almost no benefit. Accordingly, EPA could decide

that the costs and benefits of regulating one HAP is so out of balance that regulation of

any HAPs is not warranted.

In this regard, it is worth reiterating the severe lack of balance between the costs

and benefits of regulating acid gas emissions. On the cost side, acid gas regulation

comprises about half of the $9.6 billion annual cost of the rule.14 On the benefits side,

EPA produced no evidence that acid gas emissions from EGUs endanger human

health. Neither the 1998 Utility Study nor the only study that EPA subsequently

performed of the health risks of electric generator acid gas emissions,15 found any such

risks.

The best EPA could do in the regulatory preamble as to health impacts was to

express “concern” that acid gases in general are known to “contribute to chronic noncancer toxicity,” without making any finding that acid gases in the quantities emitted by

electric generators pose a meaningful risk of doing so.16 The only actual analysis EPA

performed to determine whether acid gas emissions from electric generators create a

health concern concluded that “individuals are not exposed to acid gas emissions from

Utility Units at concentrations which pose hazards to public health.”17

Even EPA’s findings as to possible environmental impacts of electric generator

acid gas emissions lacked a substantive foundation. EPA’s “evidence” of the

environmental impacts of these emissions consists of EPA’s general claim that “[i]n

areas where the deposition of acids derived from emissions of sulfur and NOx are

causing aquatic and/or terrestrial acidification, with accompanying ecological impacts,

the deposition of hydrochloric acid could exacerbate these impacts.”18 That may be true,

but it does not prove – or even lead to an inference – that electric generators emit acid

gases in sufficient amounts, given EPA’s other regulations, to create a material

environmental concern. The Utility Study did not conclude that electric generator acid

gas emissions resulted in environmental harm, and EPA did not conduct any further

study of possible environmental impacts of electric generator acid gas emissions.

The only acid gas study that EPA relied on was one study of hydrochloric acid

deposition in the United Kingdom, which EPA cites for the proposition that (a)

hydrochloric acid is highly mobile in the environment, (b) hydrochloric acid can transport

longer distances than previously thought, and (c) hydrochloric acid can be a larger

driver of acidification than previously thought.19 EPA, however, did not even try to

analyze the impact, if any, of electric generator emissions of hydrochloric acid in the

United States and, as a result, could not point to even a single instance in which

domestic electric generator hydrochloric acid emissions have affected acid deposition

anywhere or otherwise created an environmental impact.20

In fact, the “evidence” on which EPA most relied in concluding that acid gases

are worthy of regulation is that acid gases are listed under CAA Section 7412(b) and

that electric generators emit more hydrogen chloride and hydrogen fluoride than other

source categories21. But those facts, in and of themselves, are not significant given that

those emissions, even when combined with directly emitted acid gas emissions from all

other sources, do not represent more than a nominal percentage of emissions that have

the potential to result in acidification.22

Given the high costs and negligible benefits of regulating EGU acid gas

emissions, EPA has two choices. It may choose to regulate other HAP emissions while

not regulating acid gases, or it may choose not to regulate EGU HAP emissions at all.

What it cannot do, however, is simply ignore the stark mismatch of the costs and

benefits of regulating acid gases.

For the above reasons, NMA urges EPA to rescind and re-propose its

appropriate and necessary finding based on a more complete analysis of costs and

benefits.

Re:

Comments of the National Mining Association on the above-docketed

proposed rules; 76 Fed. Reg. 24976 et seq., May 3, 2011.

Dear Ladies and Gentlemen:

The National Mining Association (“NMA”) takes this opportunity to submit the

following comments on the Environmental Protection Agency’s (“EPA”) proposed

rules, as titled above, published in the Federal Register on May 3, 2011.

NMA’s membership includes the producers, transporters and consumers of

coal. Our member companies mine over 75 percent of the coal produced annually

from operations located in 26 states. Most of the coal produced by NMA members

is used by coal-fired utilities subject to this proposed rulemaking.

NMA’s members also include the transporters of coal. For example, railroads

deliver about two-thirds of all coal to coal-fired units. NMA’s members include the

producers of metals, and industrial and agricultural minerals. Their operations are

major consumers of electricity as a raw material or feedstock. Because energy

costs comprise a substantial part of their operating costs, this rulemaking will also

have a material impact upon on their global competitive position. NMA’s

membership also includes the manufacturers of mining and mineral processing

machinery and supplies. This rulemaking will affect both their markets as the

suppliers of machinery and equipment for coal mines and their competitive position

as manufacturers bearing the brunt of higher energy prices. In sum, this

rulemaking is of utmost importance to NMA.

Please let me know if you have any questions regarding NMA’s comments. I

can be reached directly at (202) 463-2608 or via email at tperry@nma.org.

Sincerely,

Thomas C. Perry

EXECUTIVE SUMMARY

I.

THE PROPOSED RULE REPRESENTS A HUGE REGULATORY BURDEN

FOR LITTLE ENVIRONMENTAL GAIN

The Environmental Protection Agency (“EPA”) has now either planned,

proposed or finalized several interrelated and costly regulations under the Clean Air

Act (“CAA”) aimed at substantially reducing the usage of coal as a fuel source in

this country. The proposed rule is no exception with its EPA-estimated $10.9 billion

in annual compliance costs. Further exacerbating the situation is EPA’s new source

emissions standards that make it virtually impossible for advanced coal-based

generating capacity to be built in this country. The reality is that as EPA continues

on its course of “leveling the playing field”1 for electric power generation in the

United States, the agency appears unwilling to grapple with the fundamental fact

that coal is the only sustainable fuel, at scale, that can reliably meet our growing

electricity needs. In a world of increasing global scarcity, the United States cannot

afford to disregard the importance of its abundant coal resources.

A. The Essential Role of Coal in the U.S. Economy

Energy is as basic to human life as food, water, clothing or oxygen.2 Access

to secure, affordable, abundant and sustainable energy from coal is the engine that

has driven American economic might for more than a century. These energy

attributes are essential to American economic success. Expensive energy chokes

off economic recovery, punishes family budgets, sends factories overseas and

determines winners and losers in global competition.

Coal is fundamental to how the nation produces electricity. Approximately

46 percent of electricity is derived from combusting coal. Coal is also by far the

nation’s most abundant source of energy, constituting 94 percent of the nation’s

fossil fuel resources. The United States has nearly 261 billion tons of recoverable

coal reserves, according to the Energy Information Administration, which is a 240year supply at current rates of use.

The correlation between coal-fueled electricity and economic growth is nearperfect.3 For example, states that rely predominantly on coal generation are

generally the states with the lowest electricity rates. Twenty of the twenty-five

states with the lowest electricity costs rely upon coal generation for at least 40

percent of their electricity generation—and all have rates below the national

average. It is no coincidence that these states also have the highest concentrations

of manufacturing.

Moreover, advanced coal technologies provide a path forward for both

retaining the country’s competitive edge and being environmentally conscious.

Supercritical coal technologies deployed in new coal-based power plants increase

efficiencies and reduce emissions by 20 percent as compared to the national

average of the existing coal-based plants. The next generation of ultra-supercritical

technologies will produce even higher efficiencies and a corresponding reduction in

emissions of 35 percent below the existing fleet of coal-based power plants.4

B. EPA’s Cost Estimate is Significantly Understated

EPA’s proposed rule disregards these important and fundamental

contributions. Moreover, even in the face of widespread retirements and sharply

increasing electric rates, EPA still continues to claim that these rules are flexible

and common-sense without any sort of credible cumulative cost analysis to support

this claim. NMA has repeatedly demonstrated the need for such an assessment,

along with providing an analytical framework for completing this important task.

Without such an assessment, EPA’s cost estimates are essentially meaningless.

EPA requires cumulative assessment under the National Environmental Policy Act

because assessing individual actions masks the overall effects that a series of

related actions will produce. For the same reason, EPA utilized cumulative analysis

to examine the effects of power plant emissions of hazardous air pollutants

(“HAPs”) in this rulemaking. EPA’s rule-by-rule cost-benefit analysis, including the

one here, similarly hides the true impacts of the agency’s overall program of power

sector regulations.

EPA’s estimated cost of this regulation is $10.9 billion per year, a cost that

this economy can ill-afford to bear. But even that number is understated given that

EPA’s underlying cost analysis suffers from a number of glaring deficiencies in

addition to the agency’s failure to assess the cumulative costs of the rule. First, the

agency’s assumption that many units will—56 GWs worth—be able to meet the

stringent acid gas standard by using dry sorbent injection (“DSI”) as an alternative

to installing costly scrubbing technology at over ten times the cost is misguided.

There is a paucity of evidence in the rulemaking demonstrating that DSI will be

effective at removing SO2 emissions at nearly as many units anticipated by EPA.

Second, EPA fails to account for the age of existing scrubbing technology in

erroneously assuming that approximately half of the fleet will meet all of the

NESHAPs without further need of retrofitting. Third, overlapping compliance

Emissions, National Coal Council Issues Paper 2009.

-2-

App.266

obligations like the Cross-State Air Pollution Rule (“CSAPR”) will effectively

foreclose the option of using DSI as those units will need to install costly scrubbing

technology in order to comply with that regulation. Taken together, these mistaken

assumptions demonstrate that EPA’s cost estimate is biased low and the projected

9.9 GW of early coal retirements is clearly understated.

Thus, as the National Economic Research Associates (“NERA”) recently

projected, based on the impact of this rule and the recently finalized CSAPR,5

compliance costs for the electric sector are a staggering $18 billion per year. The

study also estimates that nationwide average retail electricity prices rise by 11.5

percent, and heavy manufacturing states such as Ohio can expect prices to rise by

approximately 23 percent. These rules will force Americans to pay more for

electricity, including the cost of natural gas, and precipitate significant job losses

not only in coal production and transportation but also in the manufacturing sector.

C. EPA’s Benefits Analysis is Equally Flawed

EPA attempts to justify the proposed rule based on an exaggerated claim

that the proposed rule will result in $52 to 139.4 billion in health benefits.

However, the facts paint a different story as only a de minimus amount—or less

than 0.01 percent of this total benefits estimate—are expected to result from

regulating the hazardous air pollutants (“HAPs”) that are ostensibly the subject of

this rulemaking. EPA readily admits virtually all of its claimed benefits result from

the incidental collateral reduction of SO2 emissions, which in turn, reduces the

atmospheric concentrations of PM2.5, thus (according to EPA) saving lives and

improving health. However, PM2.5 is already subject to stringent regulation under

the National Ambient Air Quality Standards (“NAAQS”) program and will be further

regulated by the recently finalized CSAPR. Thus, EPA appears to be double-, and

perhaps triple-counting health benefits—or relying on benefits that would have

otherwise occurred through implementation of the NAAQS program to enhance the

appearance of justification for this rule and CSAPR.

Even more telling is the fact, as demonstrated by Figure 6-15 of the

Regulatory Impact Analysis (“RIA”), almost the entire alleged PM2.5 benefits stem

from exposures that occur below the level of the PM2.5 NAAQS. Yet EPA set that

NAAQS at a level that, as required by the CAA, the agency deems protective of

human health with an “adequate margin of safety.” Thus, despite its statements in

the preamble, in reality, even the agency does not believe the proposed rule will

produce benefits from reducing PM2.5.

The agency is preparing to propose a new PM2.5 NAAQS, and that standard

may be lower than the current NAAQS. Until it does so, however, it is inappropriate

for EPA to adopt rules based on claimed benefits below the current NAAQS level.

5

See http://www.americaspower.org/NERA_CATR_MACT_29.pdf for study results [hereinafter “NERA

Study”].

-3-

App.267

Until changed, the current 15 —g/m3 NAAQS represents EPA’s judgment of the

standard necessary to protect human health with a margin of safety. In any event,

the lowest standard contemplated by EPA is 11—g/m3. Even at this level, Figure 615 demonstrates that 80 percent of the asserted benefits would still be occurring at

levels below the NAAQS.

In sum, both EPA’s cost and benefits calculations are fundamentally flawed.

The proposed rule will be far more costly than beneficial, and EPA’s imposition of

large costs on the economy by forcing a reduction of the use of coal for electricity is

completely unjustified by any corresponding health benefit.

II.

EPA’S RULEMAKING PROCESS IS LEGALLY DEFICIENT UNDER THE

CLEAN AIR ACT

EPA has made it extremely difficult, indeed impossible, for the public to have

a meaningful opportunity to provide comments on the proposed rule. EPA’s haste

in finalizing the proposed rule by November 2011 has resulted in insufficient time

for comments, only ninety days despite the extraordinarily complex nature of the

regulation.

The rushed schedule has resulted in at least one significant error in setting

the “maximum achievable control technology” (“MACT”) standards. On May 5,

2011, the Utility Air Regulatory Group (“UARG”)6 sent a letter to EPA identifying a

critical conversion error in the agency’s calculation of mercury emissions resulting

from errors in half the mercury data used in new and existing MACT floors that

were 1000 times lower than actually measured. EPA admitted the error, but

without proper correction, the public is left to sift through the docket and discern

whether to comment on the standard in the supplemental document or the one

proposed in the Federal Register.

Another fundamental error in EPA’s rulemaking process is the agency’s

undocumented and unsupported claims of key stakeholder collaboration to

“safeguard[ing] completely against any risk of adverse impacts on electricity

system reliability.”7 NMA can find no evidence of these consultations in the

rulemaking docket. Indeed Senator Lisa Murkowski (R-Alaska) on May 17 sent a

letter to the Federal Energy Regulatory Commission (“FERC”) seeking clarification

on its collaboration with EPA.

It is inappropriate for EPA to claim that its rule will not create reliability

problems based on discussions the agency claims it is having with government and

non-government entities with direct authority over electric reliability, and yet not

include a record of those discussions in the rulemaking docket, at the time of

App.268

publication, thus affording the public an opportunity to review and comment on

these discussions.

Notwithstanding these deficiencies, on August 3—exactly one day before the

close of the comment period—Senator Murkowski announced that she has received

responses from FERC outlining the extent of its consultations with EPA.8

Preliminary review of FERC’s responses belies EPA’s exaggerated assurances of

electric system reliability. EPA must include FERC’s responses, including a record of

all the meetings between EPA, CEQ and FERC, data, and files as described in

Appendix A and B of Chairman Wellinghoff’s responsive,9 in the rulemaking docket,

extend the comment period, and provide an opportunity for public inspection and

comment.

These critical errors, in addition to several others, are directly at odds with

the rulemaking requirements under section 307(d). Under paragraph (d)(3), a

“notice of proposed rulemaking…shall be accompanied by a statement of its basis

and purpose,” and this statement “shall include a summary” of the “factual data on

which the proposed rule is based,” and the “methodology used in obtaining the data

and in analyzing the data.” In addition, “[a]ll data, information, and documents

referred to in this paragraph on which the proposed rule relies shall be included in

the docket on the date of publication of the proposed rule.” EPA has not followed

these statutory commands, as “all data” on which the proposal is based were not

included in the docket at the time the proposed rule was published in the Federal

Register.10

This type of rulemaking does little to instill confidence that the agency is

conducting an open and transparent process consistent with President Obama’s

Executive Order 13563. EPA must immediately seek an extension of the November

deadline from the Court in order to conduct a legitimate rulemaking process.

III.

EPA’S APPROPRIATE AND NECESSARY DETERMINATIONS ARE

INCONSISTENT WITH THE CLEAN AIR ACT

Congress specifically carved out electric utility steam generating units

(“EGUs”) from section 112 compliance unless and until the Administrator

determined that it is “appropriate and necessary after considering the results of”

insofar as their absence “makes impossible any meaningful comment on the merits of EPA’s assertions.”).

-5-

App.269

the public health hazards study required by that section. See § 112(n)(1)(A). In

2000, EPA inappropriately determined that it was both appropriate and necessary to

list EGUs as a source category and promulgate MACT standards under section 112.

To date, the validity of EPA’s 2000 determination has never been fully

ventilated in front of the D.C. Circuit Court. Accordingly, since EPA is reaffirming

the 2000 determination as its basis for proposing the instant rule, the legality of

that decision is squarely at issue.

EPA’s appropriate and necessary findings are contrary to the CAA and do not

comport with congressional intent. The agency’s determination that it is

“appropriate” to regulate EGU HAP emissions is based on a set of criteria outside of

the congressionally-directed public health effects inquiry, including environmental

impacts, emissions from other sources, and international cooperation. Injecting

these factors makes the “appropriate” determination so broad that it renders the

statutorily defined prerequisite for regulation meaningless. Congress clearly

wanted EPA to focus and base its inquiry on “hazards to public health” posed by

EGUs, not on a broad set of other factors. Otherwise, Congress would have simply

listed EGUs from the outset. EPA conducted a proper inquiry into whether

regulation of EGU HAP emissions was “appropriate” in 2005, but EPA has now

abandoned that inquiry and replaced it with a flawed analytical approach to mask

an insufficient factual basis for regulating. This is evidenced by the lack of benefit

derived from aggressive mercury control.

Similarly, EPA’s “necessary” finding is overly narrow and contravenes the

purpose of the subsection. EPA believes that only those requirements that

Congress directly imposed on EGUs through the CAA as amended in 1990—namely,

the acid rain program—qualifies under the necessary analysis. This legal conclusion

has no basis in the statutory language. Congress obviously knew that the 1990

amendments would result in numerous regulations potentially eliminating the need

to regulate EGUs under section 112. Even though those regulations may have been

promulgated later in time, the Clean Air Interstate Rule (“CAIR”) and CSAPR for

example, those measures qualify under the necessary analysis. Both of those

programs stem from statutory authority in place as of or before adoption of the

1990 amendments. Thus, EPA has not provided a rational basis for its illogically

narrow statutory construction. Additionally, doubts about the implementation of

the NAAQS program is an unpersuasive basis for not including the results of these

measures; compliance with the NAAQS is a legal obligation—that is why EPA

promulgated first CAIR and then CSAPR. EPA’s appropriate and necessary

determination in 2000 as well as in the instant rulemaking is arbitrary, capricious

and contrary to law.

IV.

EPA’S HAP-BY-HAP APPROACH FOR DETERMINING THE MACT FLOOR

IS UNLAWFUL UNDER THE CAA

EPA continues to set MACT floors based on an impermissible interpretation of

the CAA. The proposed MACT standards are based on a pollutant-by-pollutant

-6-

App.270

approach—or “Franken-plant” approach—relying on a different set of best

performing sources for each HAP standard.

Justice Ginsburg during the medical waste incinerator litigation offered the

following baseball analogy to highlight the apparent lack of logic in EPA’s approach.

He reasoned based on the HAP-by-HAP approach, the “best” baseball player on the

team would have the league’s highest batting average, most home runs and would

have the lowest earned run average every time he pitched. No such player exists.

Likewise, no such unit can meet all of the proposed NESHAPs on a continuous basis

without any operational or equipment upgrades.

Section 112 does not permit the agency to base MACT standards on a

hypothetical amalgamation of ideal units nor does the statue permit the “emissions

control” achieved by the best sources to be determined on a group of best

performing units. If this was the intent of Congress, it would have added specific

language so directing the agency.

The HAP-by-HAP approach violates the CAA because less than 12 percent of

existing units can actually meet all of the proposed standards. In fact, NMA’s

review of the ICR data reveals that only 3 percent of the total population of units

can meet all of the proposed standards. Moreover, this is a conservative approach

as it likely overestimates the number of compliant units because measuring below

the level once does not guarantee compliance on a continuous basis.

V.

EPA’S NEW SOURCE STANDARDS VIRTUALLY ELIMINATE NEW COAL

PLANTS

EPA’s proposed standards for new coal units are so stringent that they will

preclude construction of new coal plants that are subject to them. As reflected in

the comments of the Union for Jobs and the Environment (“UJAE”), EPA provided

UJAE with data as to which existing units comply with EPA’s proposed standards.

As set forth in that data, no existing units can comply with all of the new-unit

standards. Since no single existing unit complies with all the standards, there is no

basis to conclude that a new unit can likewise comply. EPA is required to set the

new-unit standard based on the top performing similar unit in order to ensure that

the proposed standard can actually be achieved under real world conditions. Since

no existing unit, in fact, can meet all of EPA’s new-unit standards, there is no basis

to conclude that a new unit can do so.

Again, at the heart of this issue lies EPA’s impermissible HAP-by-HAP

approach for determining the MACT floor for new sources. One or more existing

unit can meet each of the standards. But that does not mean that any existing unit

can meet all of the standards. None can.

Adopting standards effectively banning new coal units amounts to a

momentous change in national energy policy without discussion or analysis and far

exceeds EPA’s authority. Such a policy would be disastrous for the U.S. and would

undermine the most effective strategy the U.S. can implement to reduce emissions

-7-

App.271

of all kinds while preserving stable and low electric rates. That strategy is to

steadily over-time replace less efficient and older units with modern, efficient coalbased units. By a stroke of its pen, however, unless the new-unit standards have

some basis in reality, EPA will impose a de facto moratorium on the use of coal for

new electric generation.

VI.

EPA’S PERFORMANCE STANDARDS RUN COUNTER TO THE CAA

EPA’s performance standards are legally deficient in many respects. Under

section 111, the agency must consider the cost of achieving such reduction. EPA

has failed to adhere to this statutory command in setting standards of performance

for SO2 and PM2.5. Moreover, this failure is even more disconcerting considering

that EPA’s own benefits analysis clearly states that the proposed rule has little to do

with the HAPs at issue, but rather was adopted to create a regulatory backstop for

reducing ambient concentrations of particulate matter. The agency must rescind

the revisions to the standard of performance for subpart Da.

VII.

EPA SHOULD EXERCISE ITS DISCRETION TO PROPERLY TAILOR THIS

RULE

Assuming arguendo that EPA is correct in its assertion that the agency is

legally compelled to regulate non-mercury HAPs absent an affirmative health-based

finding, NMA urges the agency to exercise its discretion to properly tailor this

rulemaking consistent with the underlying record. There are two specific instances

where Congress has expressly provided EPA the tools to accomplish this objective.

Under section 112(d)(4), EPA should set a health-based standard for acid

gases. Notwithstanding EPA’s claims to the contrary, the agency has the data and

regulatory experience to set these standards. Specifically, the agency reports that

the hazard quotient for HCl never exceeded 0.05 in any of its risk assessments—or

values that are 20 to 200 times lower than the reference concentration (“RfC”) for

HCl. Failure to exercise this discretion, therefore, cannot be based on a lack of

information nor can the agency decline to exercise its discretion to preserve the

alleged “co-benefits” from SO2 and PM2.5 removal.

Additionally, EPA should further subcategorize. In the Clean Air Mercury Rule

(“CAMR”), the agency explicitly recognized the differences in emissions based on

coal types. NMA is supportive of subcategorization for lignite—notwithstanding the

beyond-the-floor measure—but the agency should further subcategorize based on

the stringent acid gas standard. According to the data EPA provided to UJAE, the

higher-sulfur coals supplied to plants in the eastern United States may not be able

to achieve the proposed emissions rate even with scrubbing technology. As such,

and without further subcategorization, the impacts on Midwestern coal suppliers will

be particularly acute. NMA urges the agency to exercise its discretion to develop a

properly tailored rule.

-8-

App.272

VIII. EPA SHOULD PROVIDE THE MAXIMUM AMOUNT OF TIME TO COMPLY

WITH THIS RULE

Requiring virtually the entire existing fleet to retrofit within a three-year

window will have serious ramifications on the amount of early retirements,

affordability and reliability of electricity, and job losses. The CAA permits the EPA

to provide an additional one-year for sources to comply with the new standards,

and the agency has used this authority before. EPA should extend this fourth year

to EGUs without exception.

Moreover, because the agency has failed to properly calibrate both the type

of needed technology and the process utilities employ in developing and

implementing a compliance program, EPA needs to investigate the flexibility

afforded by the Presidential Exception under section 112(i)(4) of the CAA. Without

the additional time afforded by this exception, the ability of utilities to comply even

with a fourth year is in doubt.

In sum, based on the numerous legal and technical flaws pervading this

proposed rule, including but not limited to the agency’s fatally flawed section

112(n)(1)(A) analysis, NMA urges EPA to withdraw the proposed rule, correct and

revise its analysis, and then re-propose based on a reasonable rulemaking

schedule. Upon reissuing the rule, EPA must take a more holistic approach that

properly tailors the regulation of EGUs under the CAA. Fundamental to this

approach is conducting a much needed cumulative cost analysis.

DISCUSSION

I.

THE PROPOSED RULE REPRESENTS A HUGE REGULATORY BURDEN

FOR LITTLE ENVIRONMENTAL GAIN

Contrary to EPA’s assertion that the proposed rule will create benefits far

higher than its cost, the opposite is the case. The benefits are exaggerated and, in

any event, will largely be achieved by other CAA programs. In contrast, the costs

will be far higher than EPA supposes because the agency’s cost projections are

based on a number of overly optimistic assumptions as to compliance strategies.

A.

The Utility MACT Rule Provides Little to No Incremental Health

Benefit

The nation’s air quality has improved dramatically since the enactment of the

CAA and its subsequent amendments. As documented in the EPA’s most recent air

quality trends report, those improvements have occurred despite the major

increase in economic and population growth:

Between 1980 and 2009, gross domestic product increased 122 percent,

vehicle miles traveled increased to 95 percent, energy consumption

increased 22 percent, and U.S. population grew by 35 percent. During the

-9-

App.273

same time period, total emissions of the six principal air pollutants dropped

by 57 percent.11

Mercury is no exception to this trend. The steps States and EGUs have taken to

reduce criteria pollutant emissions have successfully curtailed those mercury

emissions by approximately 58 percent during this period.12

Despite these facts, EPA spends much of the RIA attempting to convince the

public that the enormous costs to comply with this rule will easily be offset by the

health benefits derived from aggressive command-and-control regulation. In fact,

there is little evidence suggesting that any meaningful independent and incremental

health benefits will result from the reduction of the HAPs at issue in the proposed

rule. Of the purported $53 to 140 billion in total health benefits, the agency

estimates that the direct health benefits stemming from the regulation of the

relevant HAPs range from only $0.000005 billion to $0.006 billion per year—or less

than 0.01 percent of EPA’s total benefits estimate.13

1. Mercury emissions from EGUs pose little or no risk to public health

Beginning with EPA’s 2000 determination, the focus of regulation has been

tied to the reduction of mercury emissions from EGUs; and accordingly, the agency

declares that the proposed standards will curtail the small remaining mercury

emissions “by over 90 percent.”14 As the “HAP of greatest concern,” it would

logically follow that a significant portion of the purported health benefits would

emanate from aggressive mercury control. This is not the case as only $450,000 to

5.9 million in estimated health benefits are attributable to mercury control.15

Additionally, costly mercury curtailment options will only improve, based on

questionable assumptions, the average IQ of the most sensitive population—

children exposed in utero to high methylmercury (“MeHg”) concentrations—by only

0.00209 IQ points, which is not even meaningful in an actual IQ setting.16 Thus,

electric ratepayers in this country are going to be forced to incur billions of dollars

in annual costs without any material benefit from reducing HAPs, which is the

reason EPA ostensibly is adopting this rule.

It is unsurprising that so little health benefit would result from aggressive

mercury regulation. EPA even admitted as much when it conducted a proper

rulemaking on HAP emissions from coal-fired EGUs.17 The agency conducted

extensive modeling in preparation for CAMR to analyze how changes in mercury

emissions from coal-fired EGUs would affect mercury deposition and MeHg levels in

fish for a range of cases.18 The results of the modeling revealed that total mercury

deposition in the U.S. is not significantly impacted by mercury deposition from

EGUs, and that EGUs contribute a “relatively small percentage” to fish tissue MeHg

levels in the U.S.19 More importantly, the agency concluded “[t]hat modeling

reveals the implementation of section 110(a)(2)(D), through CAIR, would result in

a level of [mercury] emissions that would not cause hazards to public health.”20

In fact, those trends continue further bolstering the agency’s conclusion in

the 2005 Revision. Dr. Willie Soon states in his comments that power plants emit

an estimated 41-48 tons of mercury per year. But U.S. forest fires emit at least 44

tons per year; cremation of human remains discharges 26 tons; Chinese power

plants eject 400 tons; and volcanoes, subsea vents, geysers and other sources

spew out 9,000-10,000 additional tons per year.21 In short, the United States

releases less than 5 percent of the 2,400 tons of mercury emitted per year due to

human activities. U.S. coal-based power plants emit less than 2 percent of the

global total of human-caused mercury emissions. Taking into account natural

emissions, U.S. power plants contribute less than one percent of total mercury

emissions to the global pool.22

App.275

EPA disregards these findings and reverts back to its legally and factually

deficient 2000 determination in order to regulate mercury emissions from EGUs.

Specifically, EPA’s brings forward that flawed analysis by and through its current

and single analysis of mercury risk.23 The Mercury TSD, which EPA heavily relies

on, is still based on several unsupported general concerns about mercury levels in

the environment ostensibly designed to unearth some demonstrable evidence of

“risk to public health.” Like the 2000 determination, EPA has not adequately

justified its “appropriate and necessary” determination.

The agency concedes as much stating, “[t]he Mercury Study also found that

fish consumption dominates the pathway for human and wildlife exposure to MeHg

and that there was a plausible link between anthropogenic releases of Hg from

sources in the U.S. and MeHg in fish.”24 This “plausible link” was the foundation for

the 2000 determination, which is interesting, given that this same finding was

insufficient to support a regulatory determination in the Utility Study in 1998.25 In

this case “plausible” is very much a euphemism for unproven as the agency further

admits that, “…it was not possible to quantify how much of the MeHg in fish

consumed by the U.S. population results from U.S. anthropogenic emissions, as

compared to other sources of Hg.”26

To date, the agency has not provided any demonstrable evidence in the

rulemaking record to show that anyone in the country has suffered adverse health

problems as a result of mercury emissions from coal-fired EGUs. Rather, EPA is

asking the public to accept a higher cost of electricity and job losses based on an

attenuated line of reasoning—EGUs emit mercury; some of that mercury is bound

to deposit on the land or in water bodies; some of that deposited mercury in the

waterbodies can possibly be transformed into MeHg; and some of the MeHg

produced in the sediments of those waterbodies is consumed by fish where it

ultimately enters the food chain.27 In fact, valid, peer-reviewed scientific research

concluded that the level of MeHg in the world’s oceans is not controlled by

deposition of atmospheric mercury to the oceans of the world.28 Thus, regardless of

the stringency of the mercury controls required of coal-fired EGUs, the levels of

MeHg in ocean fish will not be influenced by this proposed rule.

Like the 2000 determination, the primary driver in EPA’s decision to regulate

mercury from EGUs is premised on the Mercury TSD’s highly conservative reference

dose-based hazard quotients (“HQs”) for MeHg.29 This measure compares the

potential exposure of subsistence anglers fishing in a specific water body to the

MeHg reference dose (“RfD”). UARG states in its comments that the scientific

validity of EPA’s methylmercury RfD is an important question because of its

significance as the divisor in computing the HQ value.

EPA’s RfD served as the lynchpin for two key agency “findings” to justify its

2000 determination—the existence of fish advisories in many states; and, the

number of women of child bearing age who are predicted to have MeHg exposure

above the RfD. By treating the RfD for MeHg in the December 2000 finding as an

absolute threshold for health risk, EPA avoided having to demonstrate some

discernable health risk to a segment of the population at some defined level of

predicted exposure.30

A review of the rulemaking docket reveals that EPA’s RfD is derived solely

from the results of a study involving young children in the Faroe Islands. EPA

chose to use the Faroe Islands study because it concluded that there were adverse

developmental effects as a result of MeHg exposure. Sole reliance on the study is

fundamentally flawed. First, the data underlying the analysis has never been made

See Dr. Soon Critique at 2 (affirming this sentiment by stating, “the EPA proposal neglects key scientific

knowledge and many peer-reviewed papers that suggest there is no straightforward connection between mercury

Executive Order 13563 and the Information Quality Act.31 Second, the Electric

Power Research Institute (“EPRI”) pointed out that the polychlorinated biphenyl

(“PCB”) and lead exposures of pregnant women in the Faroe Islands are among the

highest ever measured in humans—not representative of the United States.32

Moreover, the Faroe Islands study got its MeHg dosage through consumption of

highly contaminated pilot whale meats and blubbers, as admitted by Dr. Pal Weihe,

Chief Physician of the Department of Occupational and Public Health of the Faroese

Hospital System.33 EPA ignored these critical facts in relying on this study.

By contrast, EPA largely ignored the results of the Seychelles Islands study.34

The Seychelles study could not confirm any harmful effects on children through

MeHg exposure from eating a variety of ocean-caught fish, especially at levels that

are more representative for American public health. Furthermore, the underlying

data for this study has been made available to other independent scientists. By

solely relying on the Faroe Islands study, EPA’s RfD for MeHg exposure is

excessively exaggerated by at least a factor of 10 or more.

EPA also cites the existence of fish advisories to demonstrate that mercury

poses a human health concern. These advisories are tied to the RfD set for a given

compound. Accordingly, states that rely on EPA’s much higher RfD for mercury will

inevitably record a higher number of fish advisories. Fish advisories do not

distinguish among the sources of the mercury entering the waterbody at issue or

how much of the mercury came from historical sources. Moreover, the primary

purpose for fish advisories is to warn the public about undue consumption of fish

from a particular source to avoid health issues. Simply put, the number of fish

advisories does not support a legal conclusion that mercury emissions from coalfired EGUs pose risks to public health.35

As noted in UARG’s June 29, 2004 comments, Docket ID No. OAR-2002-0056, EPA’s elevation of the Faroe

Islands study over the Seychelles Island may, in part, have resulted from recommendations in the 2000 report of

the National Research Council (“NRC”), entitled Toxicological Effects of Methylmercury. That report found that

there were no serious flaws in the MeHg studies conducted in the Seychelles and Faroe Islands. The panel

recommended the use of the Faroe Islands study in deriving an RfD because it resulted in the finding of a positive

relationship between MeHg exposure and poor neurodevelopmental outcomes while the Seychelles study did not.

See IRIS Database, Methylmercury, § I.A.2, at 4-5 (2001). EPA’s reliance on the NRC report is misplaced because

the panel’s conclusion is, at bottom, a policy judgment and not a reflection of the science. Thus, the NRC strayed

beyond its initial charge. EPA needs to make its own policy judgment in setting the RfD.

App.278

EPA also ignores the fact that over 75 percent of the mercury that deposits in

the U.S. comes from sources outside the country.36 Once mercury is released, it

accumulates in the atmosphere resulting in deposition long distances from the

actual source exacerbating the lack of causal relationship between the need for

regulation and the risk posed by mercury emissions from EGUs. EPRI has

documented in recent studies the critical role that intercontinental mercury

transport from Asia and other nations play in determining U.S. mercury deposition.

Direct measurements have revealed significant levels of mercury exiting

mainland Asia and crossing the Pacific to the U.S. In 2001 and 2002, EPRI,

in cooperation with the National Center for Atmospheric Research, the

National Aeronautics and Space Administration, the National Oceanographic

and Atmospheric Administration, and other agencies used aircrafts to

measure mercury in air plumes exiting China near the city of Shanghai,

following them over the Pacific for 400 miles. A later set of flights over the

Pacific between southern California and Oregon found evidence of the same

plume crossing the California coast.37

Because mercury is emitted and transported globally, reductions of U.S. mercury

emissions from EGUs would have a negligible impact on mercury deposition in the

United States. For all of these reasons, the factual record does not support a

finding that mercury emissions from EGUs pose a meaningful health risk. It is

therefore not “appropriate” to regulate EGU mercury emissions under section

112(n)(1)(A).

2. EPA has never provided an initial finding of public health concern to

regulate non-mercury HAPs under section 112(n)(1)(A)

Nowhere in the RIA does EPA even attempt to quantify any direct benefits

associated with the regulation of acid gases, or the metallic or organic HAPs

reductions. Interestingly, of the 469 pages of the RIA only 6.5 are dedicated to

discussing the risks posed by non-mercury HAPs.38

36

EPA uses the CMAQ model in the Mercury TSD to predict mercury deposition from EGUs. UARG outlines

in its comments the serious limitations of this model when applied to small areas of localized deposition (citing to

EPRI Comments, § 3.2). The manner in which EPA choose to use the CMAQ model in the Mercury TSD overstates

the mercury deposition attributable to EGUs.

and Necessary Analysis” (Mar. 16, 2011) (“16-Unit Study”). Specifically, UARG states that EPA’s 2010 estimate of

coal usage was overstated and its prediction about the amount of pollution control equipment was grossly

-15-

App.279

As with the lack of health benefits derived from mercury control, it is also

unsurprising that no incremental health benefits accrue from regulating nonmercury HAPs. Even in 2000, the agency concluded that the existing evidence did

not demonstrate that public health concerns exist from the other HAPs. The 2000

determination stated, “arsenic and a few other metals (e.g., chromium, nickel,

cadmium) are of potential concern for carcinogenic effects and that dioxins,

hydrogen chloride, and hydrogen fluoride are of potential concern.”39 The agency

goes on the further note, “[t]he other HAP[s] studied in the risk assessment do not

appear to be a concern for public health based on available information.”40

EPA likewise did not alter this conclusion in its 2005 Revision. In fact, the

agency in 2005 bolstered the notion that it lacked the information necessary to

make this determination. “Based on the information before it at the time [of the

2000 determination], EPA could not have reasonably concluded that coal-fired

Utility Unit non-mercury HAP emissions presented a hazard to public health.”41

EPA has no better evidence now than it had in 2000. For example, none of

the acid gases are listed as carcinogenic, which is important as EPA rests its

decision to regulate acid gases based on EGU emissions of HCl. In its inhalation

risk analysis, EPA estimated HQ for HAPs that pose non-cancer health risks from

chronic exposure. If an HQ is 1.0, EPA states that estimated exposures are at a

level that is likely to be without an appreciable risk of deleterious effects during a

lifetime, but above that point, EPA considers the margin of safety against toxic

effects to be too uncertain to regulate.

EPA reports that the HQ for HCl never exceeded 0.05 in any of its risk

inhalation estimates,42 meaning that for EGUs, the predominant HAP in the acid gas

group has a maximum risk that is only 5 percent of the level that is considered

protective of health with a safety factor included. Thus, the agency itself concludes

understated. EPA needs to square its perception with reality. Indeed, EPRI modeling of every coal-fired EGU

demonstrated that the inhalation risk for every facility was below one-in-one million for carcinogens and a hazard

index of 1 for chronic (long-term) and acute (short-term) exposures to non-carcinogen HAPs.

39

65 Fed. Reg. at 79,380. In the 2005 Revision, EPA acknowledged that § 112(n)(1)(A) only allows EPA to

regulate if the agency identifies a human health concern. A finding that a HAP may pose an environmental

concern is inappropriate for regulation under § 112(n)(1)(A).

See 76 Fed. Reg. at 25,051 n. 170. Although EPA notes that other acid gases (Cl2, HF and HCN) were not

included in the risk calculation “because of uncertainties in their emissions rates,” it is hardly likely that any of

these other gases would involve an HQ so much closer to 1.0 than HCl, especially given that their total EGU

emissions are less than 15 percent of total EGU HCl emissions.

-16-

App.280

that HCl emissions pose no significant potential for exceeding the chronic RfC

value.43

Moreover, EPA does not provide any evidence that more stringent control of

acid gases would benefit ecosystems other than some vague referencing of the

possibility.

In areas where the deposition of acids derived from emissions of sulfur and

NOx are causing aquatic and/or terrestrial acidification, with accompanying

ecological impacts, the deposition of hydrochloric acid could exacerbate these

impacts. Recent research has suggested that deposition of airborn HCl has a

greater impact on ecosystem than previously thought, although direct

quantification of these impacts remains an uncertain process.44

In fact, HCl is a very minor contributor (about 1percent) of all acidification to water

bodies—making EPA’s need for regulating appear rather insignificant. EPA simply

has not provided an adequate basis to regulate acid gases from EGUs.

3. The entire rulemaking is predicated upon questionable health

benefits from an already regulated pollutant

Virtually all of EPA’s claimed benefits are derived from the incidental

collateral reduction of SO2 emissions that will occur as a “co-benefit” of reducing

acid gas emissions. To date, EPA has not been able to document any evidence of

acute or chronic health risk from exposure to the minuscule amounts of amounts of

acid gases emitted by EGUs. In other words, EPA appears to be regulating EGU

acid gas emissions under section 112(n) not because such emissions represent a

health risk—they do not—but because EPA wants to regulate SO2, which is not a

HAP. This is clearly a misuse of the agency’s authority under section 112(n).

EPA concludes that the control technology utilities will install to control acid

gas emissions will also control SO2 emissions, that reducing SO2 emissions will

reduce atmospheric concentrations of fine particles, termed PM2.5, and that

reducing atmospheric concentrations of PM2.5 will save lives and improve health.

Indeed page one of the RIA states, “[t]he great majority of the estimates [health]

are attributable to co-benefits from reductions in PM2.5-related mortality.” This is

based largely on the assertion that the proposed rule will avoid 6,800-17,000

premature deaths per year from PM2.5 exposure.

But, PM2.5 is already comprehensively regulated under other CAA programs,

in particular the NAAQS program, with EPA having set the NAAQS for that pollutant.

EPA, sources, and states under the NAAQS program are required to undertake a

44

76 Fed. Reg. at 25,050 (emphasis added).

-17-

App.281

series of actions to ensure that atmospheric PM2.5 concentrations do not exceed

the standard. Thus, any “co-benefits” the rule might achieve in reducing

concentrations of PM2.5 are duplicative of what other regulations will achieve.

Even more telling is the fact that almost the entire alleged PM2.5 benefits

($52 to 139.4 billion) stem from exposures that are occurring at levels below the

NAAQS. But EPA is required to set the NAAQS at levels protective of human health

with an “adequate margin of safety.”45 Thus, despite EPA’s claim that the proposed

rule will produce large benefits, the fact that the agency set the NAAQS at 15 —g/m3

means that, in reality, even the agency does not believe the proposed rule will

produce benefits anywhere close to those projected in the RIA.

The agency is preparing to propose a new PM2.5 NAAQS, and that proposed

standard may be lower than the current NAAQS. Until it does so, however, it is

inappropriate for EPA to adopt rules based on claimed benefits below the current

NAAQS level. Until changed, the 15 —g/m3 NAAQS represents EPA’s judgment of

the standard necessary to protect human health with a margin of safety. In any

event, the lowest standard contemplated by EPA is 11—g/m3. Even at this level,

Figure 6-15 of the RIA demonstrates that 80 percent of the asserted benefits would

still be occurring at levels below the NAAQS.

Yet EPA goes even further. In 2009, EPA made a significant change in how it

estimates deaths from PM2.5 exposure that substantially puffs up its benefits

analysis. EPA started to count mortality estimates for PM2.5 exposures below the

lowest measured level (“LML”) in any of the statistical studies on which EPA relies.

Although EPA has never set a NAAQS at a level as low as the LML, because the

agency has never believed that protecting public health required such a standard,

measuring benefits below that level lacks any basis in reality. Worse still, EPA

assumes that there is no tapering off of mortality as PM2.5 exposures approach

zero, as if the same risk exists at very low concentrations of PM2.5 as it does at

high concentrations.

This seemingly innocuous change made in 2009 had the huge impact of

assuming that people were being killed by PM2.5 exposures in the vast swath of the

United States where PM2.5 levels are less than 10 —g/m3. Whereas these areas

used to contribute nothing to estimates of PM2.5 mortality, under EPA’s new

approach, they contribute fully 70 percent of the mortality in EPA’s upper-end

estimate.

EPA’s drastic damage estimates are facially absurd. Figure C-2 from

Appendix C of the RIA shows the percentage of total U.S. deaths that EPA believes

45

See RIA at Figure 6-15 (demonstrating that almost all of the $53-140 billion in PM2.5 co-benefits are due

to reductions in exposures to PM2.5 already below the level of the current 15 ђg/m NAAQS). Figure 6.5 shows

health impacts occurring under the annual PM2.5 standard. EPA also has a daily PM2.5 standard, which the RIA

does not display similar information.

App.282

are caused by PM2.5 exposure. However, EPA’s figure only shows the lower-end of

the agency’s estimated range, perhaps because revealing the upper-end would

conceivably demonstrate how incredibly faulty the agency’s estimates are. Using

EPA’s upper-end estimates, in the areas of the country with the highest PM2.5

concentrations, 15-23 percent of all deaths are presumed to be caused by PM2.5

exposures! 13 percent of all deaths in almost all of the eastern U.S. are

attributable to PM2.5 exposures! Yet according to CDC, only 20 percent of deaths

annually are cause by tobacco.46

Indeed, the notion that PM2.5 exposures are killing people is itself a product

of a string of uncertain conclusions based on a statistical analysis. There has never

been a diagnosed death from PM2.5 exposure at ambient concentrations. The

uncertainties include: (1) the statistical detectability of thresholds and other forms

of non-linearity in true concentration-response relationships; (2) whether all

particles are equally potent, which is critical because there vast differences in

chemical composition of different forms of PM2.5; and (3) confounding and whether

observed associations are due to some other cause.

In sum, the proposed rule does not produce any meaningful monetized

benefits from reducing HAPs, which is what the rule ostensibly is supposed to do.

And the supposedly tens and even hundreds of billions of annual benefits that the

proposed rule will incidentally produce by lowering the atmospheric PM2.5

concentrations are so exaggerated as to be of no use in judging the wisdom of

promulgating this rule. On the other hand, the $10.9 billion in compliance costs

that EPA estimates, which are significantly understated, are real costs and will have

real impacts on the electric consumers that will have to foot the bill. President

Obama promised that his Administration will be diligent in eliminating unneeded

regulation and regulatory overlap. The proposed rule is a perfect example of the

type of duplicative and unnecessary regulation the President has promised not to

adopt. Yet EPA does not seem to understand the import of the President’s concern.

B.

EPA Has Underestimated the Costs of this Rulemaking

EPA likewise errs in projecting the total cost of compliance. In order to softpeddle the overall impacts to the economy, EPA relies on a series of unverified

assumptions about the type, efficacy, and quantity of needed control technology.

Chief among those speculative suppositions is EPA’s belief that dry sorbent injection

(“DSI”) technology can effectively displace the need for 56 GW of the existing fleet

to install costly scrubbers to meet the stringent acid gas emissions standards.47

Should EPA’s DSI projection not materialize to this anticipated degree, the units

46

EPA’s 2009 change in methodology accounts for some of this exaggeration. For instance, it changed the

3

estimate of premature mortality among people exposed to at least 12 ђg/m from 3 percent of all deaths to 19

percent.

that fall within the estimated 56 GW will either have to install scrubbers at over ten

times the capital cost or retire. Either option will greatly increase the cost to

comply with the proposed rule. Unfortunately, there is little data to support EPA’s

“bullish assumptions” regarding a technology not widely tested or used by EGUs for

this purpose.48

EPA must produce a cumulative cost analysis of its regulatory

program affecting the use of coal

NMA and now many other voices have repeatedly requested EPA perform an

assessment of the cumulative costs associated with its now-numerous completed,

pending and expected rulemakings that are intended to, and will, have the effect of

substantially reducing the usage of coal as an electric power and industrial boiler

fuel in the United States.49 As this rulemaking is part-and-parcel of EPA’s overall

regulatory program to develop, in its words, a “clean, efficient, and completely

modern power sector,” the agency must assess the costs and benefits of all of its

current and expected power sector regulations affecting coal-fired EGUs.

To date, EPA has provided no indication it will seriously entertain this

important request. Consequently, Congress is now considering potential legislation

to require such an assessment. EPA should not have to be compelled through

legislation to act on this repeated request. A cumulative cost assessment is logical

and would help the public and regulated entities understand the risks and rewards

of EPA’s power sector regulatory program.

Analyzing the cumulative impacts associated with these integrated

rulemakings is not only good public policy, it is also required by Executive Order

12866 and the notice and comment rulemaking provisions of the CAA. The import

of this executive order to, “tak[e] into account, among other things, and to the

extent practicable, the costs of cumulative regulations,” was recently reiterated in

President Obama’s Executive Order 135653 to improve regulations and regulatory

review.

EPA seems to recognize the interrelated nature of its rulemakings on the

power sector. In the preamble, the agency states that:

EGUs are the subject of several rulemaking efforts that are either are

or will soon be underway. In addition to this rulemaking proposal,

concerning both hazardous air pollutants under section 112 and

criteria pollutant NSPS standards under section 111, EGUs are the

subject of other rulemakings, including ones under section

110(a)(2)(D) addressing the interstate transport of emissions

contributing to ozone and PM air quality problems, coal combustion

wastes, and the implementation of section 316(b) of the Clean Water

Act (CWA). They will also soon be the subject of a rulemaking under

CAA section 111 concerning emissions of greenhouse gases. EPA

recognizes that it is important that each and all of these efforts

achieve their intended environmental objectives in a common-sense

manner that allows the industry to comply with its obligations under

these rules as efficiently as possible and to do so by making

coordinated investment decisions and, to the greatest extent possible,

by adopting integrated compliance strategies.

In addition, EO 13563 states that “[i]n developing regulatory actions

and identifying appropriate approaches, each agency shall attempt to

promote such coordination, simplification, and harmonization. Each

agency shall also seek to identify, as appropriate, means to achieve

regulatory goals that are designed to promote innovation.” Thus, EPA

recognizes that it needs to approach these rulemakings, to the extent

that its legal obligations permit, in ways that allow the industry to

make practical investment decisions that minimize costs in complying

with all of the final rules, while still achieving the fundamentally

important environmental and public health benefits that the

rulemakings must achieve.50

Unfortunately, despite recognizing the fact that utilities need to adopt an

integrated strategy for addressing all of EPA’s rules, and even with the very nearterm compliance deadlines in at least CSAPR and the instant rulemaking, EPA states

that it will not begin to consider coordinated control strategies until the New Source

Performance Standard (“NSPS”) for greenhouse gas emissions rulemaking. At that

time, EPA says it will “facilitate the industry’s undertaking integrated compliance

strategies in meeting the requirements of these rulemakings.”51 While NMA is

mindful of EPA’s recognition that the power sector needs to have the full benefit of

understanding all of the relevant regulations before determining a compliance plan,

EPA’s undertaking to address coordinated strategies at the NSPS rulemaking stage

is too little, too late. Eastern utilities must begin to complying with CSAPR in

January. When EPA finalizes the instant rule in November, utilities will have only

three years to comply. It would have been far better had EPA undertaken the

process it now plans when it initiated its first rulemaking impacting the power

sector.

The agency’s planned process also does not go far enough. EPA has an

obligation not just to help the regulated community plan for all of these interrelated

regulations; it must also cumulatively assess the societal impacts of these

regulations. A key purpose of Executive Order 12866 and 13563 is to inform the

public of the costs and benefits of regulation, including on a cumulative basis.

Notwithstanding the statements of integrated planning in the proposed rule, it does

not appear that EPA intends to provide such an analysis. It should.

Taken together, this regulatory program will undoubtedly produce a dramatic

and cascading series of impacts not only within the coal industry but across the

entire economy. There will be direct effects on coal employment and indirect

effects on employment generally in the economy as a result of higher energy

prices. Higher energy prices will also affect GDP and economic activity generally.

American competitiveness will also be affected, as higher prices undermine the

ability of American businesses to compete, with resulting offshoring of American

business and jobs. The public has a right to fully understand these impacts.

2.

EPA’s DSI assumption is misguided

The implications of the DSI issue cannot be overstated. For such a crucial

piece of the compliance puzzle there is a paucity of evidence demonstrating that an

actual unit can comply with all of the proposed NESHAPs using DSI without a

scrubber. NMA’s review of the rulemaking docket reveals only two source materials

attempting to support EPA’s DSI theory. Based on the first source, EPA claims that

“HCl removal effect is assumed to be 90% based on information from Solvay

Chemicals.”52 The only support for this conclusory statement is a reference to a 12page slide presentation; hardly persuasive in light of the import the agency places

on this assumption. Moreover, this presentation was predicated on sodium

bicarbonate injection—not Trona—therefore, the agency’s predicted feed rates are

inaccurate.

Second, the agency relies on “assessments” between engineering staff and

the consulting firm of Sargent & Lundy. These “assessments” only contain a

general statement that “demonstrations and recent utility testing have shown SO2

removals greater than 80% for systems using sodium based sorbents.”

Importantly, the report does not analyze the technology for its proposed

application—namely, compliance with the full suite of NESHAPs and the impact the

technology may have on particulate matter and mercury emissions.

on EGUs considered DSI a viable acid gas control option without a scrubber.53 The

U.S. Energy Information Administration (“EIA”) in its 2011 Annual Energy Outlook

likewise doubts EPA’s DSI assumption noting that, “other analyses are not as

optimistic on the prospect of DSI,” leading the agency to conclude that scrubbers

will be needed to comply with the proposed rule. Yet EPA does not seem inclined to

engage in a realistic analysis of the issue.

There are at least three primary reasons for the lack of enthusiasm around

the efficacy of the DSI technology. First, there is limited industry experience

employing the technology to control acid gases without a scrubber. The ICR data

base indicates that there are only 28 units or 9 GWs of DSI capacity in the Base

Case of the model primarily to deal with SO3 reduction—only eleven are used for

SO2 control. According to our review of the information, among the top 12 percent

of the units that set the MACT floor for acid gases, only 15 use DSI technology. Of

those 15 units, only 5 use DSI without a scrubber and only one of those units burns

bituminous coal.54

It is also difficult to precisely calibrate the overall effectiveness of DSI

because the EPA database is missing fuel chlorine data for at least eight of the

listed DSI-only units. Removing these units from the evaluation, leaves only 2

units from the smaller group of eleven—those with proper emissions data—using

DSI without a scrubber, but both of these units are burning low chlorine content

coal. Thus, it is impossible to discern whether any actual unit can effectively and

consistently meet the proposed acid gas standards as a direct result of having

employed DSI technology.

NMA finds it difficult to believe a utility would consider investing in a

technology with such limited industry testing and experience, high variable costs

and other ancillary issues including negative impacts on ash impoundments and

potential leaching. The agency’s aggressive rulemaking schedule makes it

challenging for a utility to obtain the essential on-the-ground testing information to

validate performance and conduct necessary feasibility studies. Moreover, the lack

of experience with the technology also highlights the problem with setting

emissions standards pollutant-by-pollutant as there is also insufficient data to

confirm whether a unit using DSI with or without a scrubber can meet all three

standards on a continuous basis without creating antagonistic impacts to the overall

effectiveness of other control technologies.

App.287

EPA is also making this DSI prediction in a regulatory vacuum. Many of the

units within the scope of the 56 GW will not have the option to choose this

compliance route because overlapping CAA rules will render that decision moot.

The recently finalized CSAPR is designed to reduce the interstate transport of SO2

and NOx from EGUs in 27 eastern states. Importantly, 464 of the 521 units without

scrubbers are located within the geographic reach of CSAPR. Even though a

modest trading program is part of the regulation, a significant portion of these units

will need to install scrubbing technology to comply with the rule beginning in 2012.

The issue of overlapping technology demands is not directly addressed in the

RIA other than some vague referencing to integrated planning in the preamble after

the proposed NSPS for GHGs from EGUs are issued. This lack of analysis further

reinforces the need for a cumulative cost analysis by the agency. Neither a utility

nor a public utility commission would permit the investment in DSI technology and

sorbent storage facilities only to have to install a scrubber two years down the road.

EPA must examine what portion of the estimated 56 GW will actually choose DSI

given EPA’s other regulations in order to provide a realistic estimate of the costs of

this rule.

Third, not every coal type within the projected 56 GW will be able to meet

the stringent acid gas standard using only DSI. The DSI consultant EPA relies on,

Sargent & Lundy, states that “[t]he DSI technology should not be applied to fuels

with a sulfur content of greater than 2 lb SO2/MMBtu.”55 This statement buttresses

the conclusion advanced by the above paragraph—which is, DSI is rarely employed

without a scrubber and is almost never used with units burning coal with high sulfur

content.

Despite the consultant’s assessment, EPA projects the exact opposite stating

“[m]any available pollution controls achieve emissions removal rates up to 99

percent (e.g. HCl removal by new scrubbers), which allows industry to rely more

heavily on local bituminous coal in the eastern and central parts of the country that

has higher contents of HCl and sulfur, and is less expensive to transport than

western bituminous coal.”56 Part of this oversight is attributed to the various

assumptions and biases built into the Integrated Planning Model that result in

biased low projections of compliance costs. The model is designed to determine the

most cost effective means of meeting electric generation capacity requirements

given certain constraints. Thus, the model permits a unit to both select the lowercost DSI technology and take advantage of lower cost local bituminous coals. This

is not a realistic choice for a utility. EPA needs to reexamine the interplay between

the use of DSI without a scrubber using local bituminous coal in order to provide an

accurate assessment of the compliance costs.

Clearly, without a realistic assessment of the market penetration for DSI,

EPA cannot provide a reasonable cost estimate of the proposed rule. NMA projects

that based on a more grounded assessment of DSI, the cost of complying with just

the acid gas standard could be over three times EPA’s projection, totaling almost

$12 billion/year casting further doubt on EPA’s overall projection of $10.9 billion per

year for the entire proposed rule.57

For purposes of this projection, NMA revised EPA’s cost estimates with a more realistic assessment of the

market penetration for DSI. We assumed an additional 119 MW of scrubber installations, thus Tables 1 and 2

reflect the cost of acid gas compliance for the 521 units without scrubbers. Methodology: As a preliminary matter,

it is not clear what EPA’s total projected compliance costs are. EPA claims that it uses an 11.3 percent capital

charge rate, or roughly a nine year payback period for economic analyses in the model (“Documentation for EPA

Base Case v4.10 Using the Integrated Planning Model,” at 8-14). The Agency also refers to a 20-year depreciation

schedule for environmental retrofits (IPM Background Document at 8-11). Based on our calculations, it appears

that EPA has multiplied total compliance cost estimates by 11.3 percent to arrive at annual costs. So, for example,

an annual capital cost of $1,421 million/year for “Dry FGD and Fabric Filters” corresponds to a total cost (excluding

consideration of the time value of money) of $12,565 million, spread over an approximately nine year period. We

will apply the 11.3 percent capital charge rate to our total cost estimates to compare them with EPA’s annual

projections.

For calculating scrubber capital and fixed operating and maintenance (“FOM”) costs, NMA used Table 5-4 of the

IPM Background Document, along with heat rate and capacity information from the NEEDs database, for the 521

units that do not have a scrubber. Based on the primary fuel listed in the NEEDs database, we assume units

burning bituminous coal would install wet FGD systems and those burning subbituminous or

bituminous/subbituminous blends would install dry FGD systems. Of those 521 units, 439 do not have fabric

filters. For calculating fabric filter capital and FOM costs, we used Table 5-24 of the IPM Background Document,

along with the NEEDs database. For variable operating and maintenance (VOM) costs, which are based on kilowatt

hour (kWh) assumptions, NMA used the ratio of EPA’s variable to fixed O&M cost projections.

EPA needs to reexamine this critical assumption with actual on-the-ground testing

to determine if both the efficacy and unwanted environmental side effects of DSI

makes it a viable control technology.

3.

Many analysts have predicted higher amounts of early coal

retirements

EPA’s claim of “common-sense” rulemaking is, in large part, intertwined with

its DSI assumption. If EPA’s unsupported assumption as to the number of units

that can install DSI as a compliance strategy is wrong, the costs of complying with

the acid gas standard could potentially triple, as many more units will have to

install or upgrade costly scrubbing technology. This increased cost will

correspondingly result in more retirements and higher electricity prices as many

units will not be able to absorb the additional cost. This fact invites legitimate

criticism of the agency’s 10 GW retirement figure. For example, and in addition to

the below chart,58 FBR Capital Markets states that “…the practical applicability of

DSI remains a debatable point due to the additional ash produced, reliability of the

reagent supply chain, lack of utility sector experience with this technology, and the

potential impact of dispatch. More limited adoption of this technology could lift the

retirement number above 50 GW.”59

58

It is important to note that each projection employed a different set of assumptions to arrive at the

retirement projection—i.e. some studies analyzed the proposed rule in isolation, while others like NERA analyzed

the instant rule in conjunction with other related CAA rules. The chart highlights EPA’s glaring need to provide a

cumulative cost estimate of all of these rules.

Even using EPA’s own data it is entirely plausible that 50 GW will be forced to

retire based on this suite of rules. The agency’s 9.9 GW retirement figure is based

on forecasting the Utility MACT rule in isolation, rather than examining the agency’s

own base case of 25 GW gross retirements. EPA’s base case estimates 299 GW of

coal generation in 2015, which is an 18 GW decline in coal capacity from 2010

based on the implementation of CSAPR and Utility MACT. The base case also

assumes, albeit optimistically given the inability to construct new coal plants with

the stringent new source standards, an additional 7 GW in coal additions during this

time.

However, this entire projection is built upon full market penetration of DSI or

56 GW. Even assuming optimistically that the deployment of DSI is even half the

forecasted rate, which is reasonable given that half of the units targeted for DSI

deployment operate without scrubbers and burn medium or high sulfur coal, the

retirement number could easily jump to 50 GW. Nowhere in the record does EPA

engage in this sort of analytical rigor. Rather, the agency simply assumes the best

without any factual support resulting in a flawed rule with an inaccurate assessment

of the true impacts.

4.

EPA’s mistaken beliefs about the current fleet will also increase

the amount of projected retirements

The issue of flawed retirement projections is not confined to the DSI

assumption. Another aspect of this issue stems from Administrator Jackson’s faulty

statements regarding the state of the current fleet. In the proposed rule, EPA

60

Each individual analysis is filed contemporaneously with these comments (Attachment 7).

-27-

App.291

notes that “[t]oday over 50 percent of the power generation fleet has scrubbing

technology installed and the industry is already working on installations to bring

that number to nearly two-thirds of the fleet by 2015.”61 This statement is

seriously misguided and suggests that existing units with scrubbers will not have

any compliance costs associated with this proposed rule. NMA seriously doubts EPA

would be willing to offer this type of safe harbor treatment to existing coal-fired

EGUs.62

This statement also does not seem to comport with other portions of the

preamble where the agency predicts that “…the proposed rule will require

companies to make a decision—control HAP emissions from virtually uncontrolled

sources or retire these sometimes 60 year old units and shift their emphasis to

more efficient, cleaner modern methods of generation, including modern coal-fired

generation.”63 Notwithstanding this apparent contradiction, Administrator Jackson

further reinforces this unsupported conclusion by noting one of the principal

objectives of this rule:

Utilities that have already put pollution control technology in place will no

longer have to compete with those who have delayed those investments—a

group that includes almost half the nation’s coal-fired plants, which lacked

advanced pollution control equipment. In fact, facilities that have already

taken responsible steps to reduce the release of toxins into our air will be at

a competitive advantage over their heavy-polluting counterparts. And to

ensure cost-effectiveness, we have proposed flexibility in meeting the

standards.64

These statements are fundamentally flawed. Over half of the scrubber in the

referenced 50 percent of units will be at least 20 years old and at the end of their

useful life by 2015. Thus, significant costs will be associated with upgrading

existing scrubbers to achieve compliance with the proposed standards. Typical

scrubber modifications to improve SO2 absorption include improving gas flow

distribution, reconfiguring spray headers, adding frothing trays and increasing

recycle flow. Furthermore, many existing scrubbers were built when the CAA only

62

Furthermore, EPA should recognize that the MACT process sets the standard at the average of the top 12

percent, essentially at the 94th percentile, thus only 6 percent of units ostensibly should meet the standard

without modification. Because about half of the units in the U.S. are unscrubbed, that 6 percent can only

accommodate about 1/8th of the scrubbed units. That is, seven out of eight scrubbed units will have undertake

some level of modification.

required 70 percent SO2 removal. Based on this standard, scrubbers typically

included partial FGD bypass and only modest SO2 removal in the absorber.

Bringing these units up to the proposed emissions standards will likely require more

than simply modifying spray headers and adding absorber trays. A more accurate

analysis of this particular issue could double the projected upgrade costs for older

units built before 1995 thereby increasing the number of retirements.

Utilities cannot make important investment decisions based on unverified

assumptions and without considering the implications of the cost of recovery of

these retrofits. Especially for older, less efficient plants the capital break-even

point between installing, retiring or fuel switching when assessed in light of these

multiple regulations makes it highly unlikely that EPA’s view of the utility industry is

accurate. This is evident in American Electric Power’s assessment that these

interrelated air rules will force the utility to prematurely shutter about 25 percent of

its current coal-fueled generating capacity, or 6,000 megawatts.65

5.

EPA’s assessment of impacts on electricity prices and job losses is

premised on questionable assumptions and an inadequate

rulemaking record

Taken together, because EPA has missed the mark in projecting early

retirements based on a series of questionable assumptions, the affordability and

reliability of electricity will accordingly be uncertain. EPA attempts to blunt this

criticism by claiming that “[t]he energy savings driven by these energy efficiency

policies mean that consumers will pay less for electricity as well. EPA has modeled

national average retail electricity prices, including the energy efficiency costs that

are paid by the ratepayer. The Toxics Rule increases retail prices by 3.7 percent,

2.6 percent and 1.9 percent in 2015, 2020, and 2030 respectively relative to the

base case.”66 This statement has limited heuristic value when factoring in the

aforementioned assumptions coupled with the overreliance on modeling that fails to

appropriately examine the issues on a regional basis, like the Midwest or Southeast

where coal is the dominant fuel for electricity.

Part of EPA’s problem in assessing the increase in electricity prices lies in the

implicit biases of its model. The overriding principle of the model is to maintain

adequate generating capacity and target reserve margins in each of the 32

modeling regions.67 In order to maintain adequate resources in each region, the

App.293

model assumes that regions with excess supply will absorb the capacity lost by

retirements. Stated differently, according to the model, retirement decisions are

first a product of geography rather than on a realistic business decision. The

following illustrates the problems with the model:

The model projects retirements of three 750 MW units or 2,250 MW at

the Navajo power plant in Arizona. The units were built in 1974-76

and have wet scrubbers operating at 92 percent efficiency. On the

other hand, seven units in Northern Illinois totaling 2,017 MW built in

1952-59 without scrubbers, SCRs or fabric filters would continue to

operate. The difference is the location. The AZNM modeling region

has more excess capacity than the COMD region of northern Illinois.

Unfortunately, the model may have placed too much faith in

maintaining resource adequacy, particularly given the number of

investor owned utilities. As a result, the projected number of

retirements is unrealistically low. Alternatively, if the model’s

complete faith in resource adequacy proves correct, electricity costs

will increase dramatically in certain regions such as the COMD

modeling source.

EPA cannot wholly rely on this model to accurately analyze this important issue.

EPA also attempts to fall-back on early collaboration with key stakeholders to

prevent the potential for skyrocketing electricity prices and job losses. The agency

states that, “[i]n addition, EPA itself has already begun reaching out to key

stakeholders including not only sources with direct compliance obligations, but also

groups with responsibility to assure an affordable and reliable supply of electricity

including state Public Utility Commissions (PUC), Regional Transmission

Organizations (RTOs), the National Electric Reliability Council (NERC), the Federal

Energy Regulatory Commission (FERC), and DOE.”68 EPA further states, “[i]t is

EPA’s understanding that FERC and DOE will work with entities to ensure an

affordable, reliable supply of electricity….”69 As mentioned in the Executive

Summary, NMA can find no evidence of these consultations in the rulemaking

docket.

More specifically, the public has no ability to discern whether EPA is

presenting the implications of this rule with its overly optimistic DSI assumption

thereby coloring the perceptions of the stakeholder.70 Interestingly, as of October

2010, NERC as one of the identified stakeholders did not share EPA’s view of de

minimus impacts to electric power generating sector.

Overlapping compliance schedules for the air and solid waste regulations,

along with the required compliance for rule 316(b) following shortly

thereafter, may trigger a large influx of environmental construction projects

at the same time as new replacement generating capacity is needed. Such a

large construction increase could cause potential bottlenecks and delays in

engineering, permitting and construction. 71

Based on this assessment, either NERC has changed its position since this time to

align with EPA based on information not included in the rulemaking docket, or EPA

is not being forthcoming about the reality of these “collaborations” to deal with this

important issue. In any event, and unsurprisingly, the foregoing demonstrates that

FERC—responsible for delivering reliable electricity to the country—is not as

confident in EPA’s assessment of the situation as EPA portrays it to be.

Following FERC’s responses to Senator Murkowski, NMA joins the Senator’s

extreme concern with the impending situation, as described in her August 3 press

release, “[h]aving received FERC’s responses this week, I must say that I am now

less confident [after initially hearing the Chairman’s plans for an interagency task

force] of that being the case.” Preliminary review of FERC’s responses completely

validates her position.

In response to EPA’s exaggerated representations in the preamble, Chairman

Wellinghoff stated in his letter, “…this information assessment offered only a

preliminary look at how coal-fired generating units could be impacted by EPA rules,

and is inadequate to use as a basis for decision-making, given that it used

information and assumptions that have changed.” (emphasis added). This

sentiment is further confirmed in Commissioner Moeller’s response, “[a]ccording to

OER staff, EPA’s reliability analysis has been limited,” and that staff have, “pointed

out to EPA that a reliability analysis should explore transmission flows on the grid,

reactive power deficiencies related to closures, loss of frequency response, black

start capability, local area constraints, and transmission delivery.” (emphasis

added). In sum, EPA’s “trust us” mentality has far underestimated the complexity

underlying the delivery of affordable and reliable electricity.

This is further evidenced by the fact that neither FERC nor EPA has

conducted a cumulative impacts analysis. Furthermore, FERC’s assessment that 81

GW of “likely or very likely” retirements may result from the implementation of this

suite of rules, further highlights the need—as expressed by NMA—for a more

transparent and open process to deal with these important issues. Recognizing the

Chairman’s reservations about the results of this preliminary study, it nevertheless

71

Environmental Regulations, October 2010.

-31-

App.295

highlights EPA’s failure to disclose this critical study and any other material that

may exist regarding the EPA-FERC consultation process.

NMA joins Commissioner Moeller’s recommendations to have FERC: (1) use

its expertise to perform an analysis of EPA’s rules that could impact reliability of

electricity—and disclose that analysis for public comment—and then hold a technical

conference for public input; and (2) have EPA extend the timing of these

regulations as the agency’s schedule “does not conform to the relevant planning

horizons in the electric sector of our economy, one of the most capital-intensive

sectors of industry.”

Furthermore, the understatement of potential coal-fired EGU retirements and

electricity prices will be especially acute if EPA holds the line with its new source

emissions limits. As will be discussed below, the new source emissions standards

based on the impermissible HAP-by-HAP approach makes it difficult to foresee

investment in new coal. Credit Suisse projects that at a 60 GW retirement figure,

there would need to be an additional 24 GW just to maintain reserve margins at 15

percent begging the important question of where will coal-dependent regions of the

county replace these important sources of energy.72 Despite EPA’s effort to “level

the playing field,” the agency has done an inadequate job of informing the public as

to the consequences of such a policy.

Unfortunately, where EPA’s miscalculations will be most felt is the additional

burden to rate paying customers. Public Utilities Commissions can hardly ask for

the type of rate increase needed to offset these capital costs during times of

economic prosperity let alone in the current economic condition. These consumer

energy costs represent the most regressive de facto tax regimes as areas of the

country reliant on coal-derived energy will rapidly become the most expensive.

This is especially true for the “rust belt” region and states in the southeast that will

be heavily impacted by EPA’s faulty assumption that EGUs will shift to local

bituminous coal based on DSI use, thus masking the overall jobs impact on these

economically challenged areas.

In fact, the market—contrary to EPA’s overly optimistic prediction—has

already responded to the added pressure of these numerous CAA rulemakings. On

May 26, 2011, Louisville Gas and Electric announced its plans to request a raise in

residential electric bills by about 19 percent by 2016 in order to pay for upgrading

its coal-fired power plants to meet rules promulgated pursuant to the CAA.73 This

dramatic increase is also reflected in the NERA study concluding that average

electricity prices will increase by around 12 percent nationwide, with regional

increases as much as 24 percent.74 If EPA is unwilling to modify the proposed rule

and properly tailor its provisions to address environmental concerns and ensure

reliable and affordable energy, the U.S. economy will undoubtedly suffer as a

result.

Lastly, Administrator Jackson in her remarks at the signing ceremony for the

proposed rule noted the uptick in so-called “green jobs” that would result from

implementation of this rule. 75 While it may be true that some jobs will be created in

order to install the requisite control technology, the overall economic impact of

plants being forced to retire, no foreseeable construction of new coal-fired plants,

the “multiplier” effect of job losses in sectors such as coal mining, and the expected

increase in electricity prices of more costly energy sources cannot even begin to be

offset by these so-called “government-created” jobs. The recent NERA study

projects that the combination of CSAPR and the present rulemaking will result in

nationwide net employment losses totaling 1.44 million job-years by 2020. These

net losses take into account these “green jobs” as well as the jobs lost by these

regulations. In other words, employment losses under only these two EPA

regulations will outnumber gains by more than four to one through 2020.

David Montgomery of Charles River Associates, an economist with 40 years

of work in energy and environmental policy recently testified before Congress and

shed further light on the “green jobs” claim:

The serious debate in environmental policy is about how the costs of new

regulations compare to their benefits, and how to design the regulations to

minimize costs, uncertainty and disruption. Claims that regulations that

raise the cost of doing business will create new jobs are, at best, a sideshow.

Such claims only distract attention from the difficult tradeoffs that must be

made between costs and benefits. ‘Green jobs’ is not a subject that leading

economists have usually taken seriously enough in professional journals.76

Based on the foregoing, it is difficult for EPA to legitimately claim that the proposed

rule’s benefits analysis is accurate.

II.

EPA’S RULEMAKING PROCESS IS LEGALLY DEFICIENT UNDER THE

CLEAN AIR ACT

EPA has made it extremely difficult, indeed impossible, for the public to have

a meaningful opportunity to provide comments on the proposed rule. EPA’s haste

in finalizing the proposed rule by November 2011 has resulted in insufficient time

for comments, only ninety days despite the extraordinarily complex nature of the

proposed rule. As the agency is fully aware, the proposal published in the Federal

Register is 171 pages long and includes new MACT and new performance standard

limits and compliance requirements for coal-fired EGUs as well as a new section

112(n)(1)(A) analysis. Moreover, there are over 19 technical support documents

and a more than 500-page RIA in the rulemaking docket.

Furthermore, EPA has provided more time for public comment on other

rulemakings that were both narrower in scope and less costly to the overall

economy than the current proposal. For example, EPA augmented the original 60

day comment period for the Portland Cement MACT rule with an additional 60 days

to ensure sound public participation on the 163 existing facilities (as compared to

this rule’s 1,200 existing units) at issue in the proposed rule.77 While NMA is

mindful of the 30-day extension, there is no reasonable explanation for why the

agency insists on adhering to an unreasonable final deadline to deal with a

rulemaking of this magnitude and significance. Given the agency’s recent

experience with the Industrial Boiler MACT consent decree and self-initiated

reconsideration period, the agency should immediately recognize the undesirable

results of a truncated rulemaking schedule.

The rushed schedule has already resulted in at least one significant error in

setting the MACT standards. On May 5, 2011, UARG sent a letter to EPA identifying

a critical conversion error that an NMA member company found in the agency’s

calculation of mercury emissions resulting in new and existing MACT floors that

were 1000 times higher than the emissions identified in the dataset for those units.

UARG requested the agency re-propose the rule to properly correct the mistake.

EPA refused this request thereby failing to comport with the notice requirements of

CAA § 307(d)(3).

Instead, EPA admitted the error and proposed to correct it by inserting the

correction into a technical support document adding to an already cumbersome

rulemaking docket. Rather than provide a Notice of Data Availability, the public is

left to sift through the docket and discern whether to comment on the standard in

the supplemental document or the one proposed in the Federal Register. Despite

this and other important errors groups like UARG continue to discover with the

proposed rule, EPA refuses to accommodate an adequate rulemaking period,

undermining confidence that the agency is conducting an open and transparent

rulemaking process consistent with the President’s Executive Order.

Furthermore, the failure to provide evidence of the communication between

FERC and other key stakeholders regarding the electric reliability issue is

inexcusable. EPA cannot claim it has adhered to the statutory requirements of the

CAA without installing all records related to these consultations and permitting the

public an opportunity to meaningfully comment. More importantly, given FERC’s

reservations about EPA’s portrayal of the situation, there is a glaring need for more

serious collaboration on this issue with an opportunity for public participation. EPA

must not sacrifice electric affordability and reliability at the feet of an arbitrary

regulatory calendar.

These errors are directly at odds with the rulemaking requirements under

section 307(d). Under paragraph (d)(3), a “notice of proposed rulemaking…shall be

accompanied by a statement of its basis and purpose,” and this statement “shall

include a summary” of the “factual data on which the proposed rule is based;” and

the “methodology used in obtaining the data and in analyzing the data.” Lastly,

paragraph (d)(3) instructs that “[a]ll data, information, and documents referred to

in this paragraph shall be included in the docket on the date of publication of the

proposed rule.” EPA has not followed these statutory commands as the

requirement to provide “all data” on which the proposal was based was not included

in the preamble nor in the docket at the time the proposal was published in the

Federal Register.78

The D.C. Circuit Court of Appeals has held that the public notice and

comment requirements “are designed (1) to ensure that Agency regulations are

tested via exposure to diverse public comments, (2) to ensure fairness to affected

parties, (3) to give affected parties an opportunity to develop evidence in the

record to support their objections to the rule and thereby enhance the quality of

judicial review.”79 These objectives have been undermined in this rulemaking

process. Moreover, there are indications in the preamble that regardless of the

public input, EPA has a predetermined outcome in mind when it crafted these

proposed regulations. The proposed rule states, “…EPA expects that sources will

begin promptly, based upon this proposed rule, to evaluate, select, and plan to

implement, source-specific compliance options.”80 The Court’s holding highlights

the issue of whether EPA’s unreasonable timeframe will effectively prevent the

agency from being responsive to public comments—e.g., technical errors; lack of

evidence to support §112(n)(1)(A) analysis; impermissible MACT standards under

section 112; health based standards; further subcategorization; and recognition

that dry sorbent injection cannot resolve the acid gas issue.

insofar as their absence “makes impossible any meaningful comment on the merits of EPA’s assertions.”).

In light of these rulemaking concerns, NMA urges EPA to promote an open

and transparent rulemaking process by immediately seeking an extension of the

current final deadline. The court acknowledged that the consent decree does

permit extension. “The Court appreciates industry’s concern that this schedule may

be too hasty for the critical and expensive regulatory decisions that will be made;

however, the proposed Consent Decree allows for a change of schedule if need

be.”81 In fact, the judge added that if the scientific and factual basis for the

rulemaking requires more time, “EPA can obtain it.” NMA urges EPA to immediately

seek an extension.

EPA’S APPROPRIATE AND NECESSARY DETERMINATIONS ARE

INCONSISTENT WITH THE CLEAN AIR ACT

The proposed rule is based on a fundamental misreading of section

112(n)(1)(A). Congress purposefully treated EGUs differently than other source

categories under section 112. Section 112(n)(1)(A) states:

The Administrator shall perform a study of the hazards to public health

reasonably anticipated to occur as a result of emissions by electric utility

steam generating units of pollutants listed under subsection (b) of this

section after imposition of the requirements of this Act. The Administrator

shall develop the results of this study to the Congress within 3 years after

November 15, 1990. The Administrator shall develop and describe in the

Administrator’s report to Congress alternative control strategies for emissions

which may warrant regulation under this section. The Administrator shall

regulate electric utility steam generating units under this section, if the

Administrator finds such regulation is appropriate and necessary after

considering the results of the study required by this subparagraph.

Based on the foregoing, Congress clearly did not intend to automatically subject

EGUs to the normal “list and regulate” scheme of sections 112(c) and 112(d).

Moreover, under this section, EPA could not regulate at all until it completed a

study of the “hazards” to public health “reasonably anticipated to occur” as a result

of HAP emissions from EGUs and then, only after considering the reductions of

those hazards that would occur as a co-benefit of regulation of EGUs under other

provisions of the CAA. Furthermore, the agency was directed to “develop and

describe” alternative control strategies for emissions for any HAP emissions that

“may warrant regulation under this section.” Lastly, EPA could only regulate under

section 112 if it found, after proper notice and comment rulemaking, that regulation

of these units was “appropriate and necessary” after considering the results of the

public health hazards study.

The history of EPA’s various attempts at regulating mercury and other HAP

emissions from EGUs under this provision is well-chronicled both in the preamble to

the proposed rule and in UARG’s comments. Importantly, there are two

App.300

inescapable facts that EPA must grapple with in its decision to not only regulate

mercury emissions, but also to extend the 2000 determination as the foundation for

regulating all non-mercury HAPs under section 112(d).82 First, the factual record

and legal issues underpinning the December 2000 determination83 has never been

fully ventilated in front of the D.C. Circuit. The D.C. Circuit’s vacatur of CAMR

focused exclusively on the criteria for removing or delisting EGUs from the list of

section 112(c) major source categories.84 Accordingly, EPA’s authority to regulate

EGUs under section 112(d) is directly at issue during this rulemaking.85

Second, not only is EPA’s requisite factual predicate finding under §

112(n)(1)(A) for mercury legally deficient, but the agency has not even attempted

to undertake the same level of analysis for any other HAP it is proposing to

regulate. EPA mistakenly believes it is legally compelled to regulate all HAPs under

this regulatory construct stating, “…we interpret the statute to require the Agency

to find it appropriate to regulate EGUs under section 112 if the Agency determines

that the emissions of one or more HAP emitted from EGUs pose an identified or

potential hazard to public health or the environment at the time the finding is

made.”86 NMA joins UARG in its disagreement with this legal conclusion.

In addition to these and other serious flaws, NMA contends that EPA’s

interpretation of the term “appropriate” is so overbroad that it renders the entire

analytical exercise required by Congress utterly meaningless. While EPA is correct

that it has the discretion to define the contours of the inquiry within the bounds of

reasonableness, it cannot merely pay lip service to the fact the agency throughout

this entire process has maintained that “[s]ection 112(n)(1)(A) therefore sets an

important and unique condition precedent for regulating Utility Units under section

82

Additionally, the Court did not opine on the legal and factual substance of EPA’s 2005 Revision that it was

not appropriate and necessary to regulate mercury emissions from EGUs.

83

On December 14, 2000, then-Administrator Browner published a “notice of regulatory finding.” This socalled notice stated the Administrator’s “conclusion” that regulation of mercury emissions from EGUs was

“appropriate and necessary” under section 112. See 65 Fed. Reg. 79825 (Dec. 20, 2000).

112….”87 EPA has not heeded this Congressional direction in the proposed rule as

its interpretation of “appropriate” effectively overrides the primary congressional

command to analyze “hazards to public health reasonably anticipated to occur”

from EGUs.

Conversely, in order to ensure that EGUs are regulated under section 112

thereby leveling the market for electricity in the U.S.,88 EPA’s “necessary”

interpretation is so narrow that it precludes consideration of the many measures

under the CAA that have proven to effectively reduce mercury and HAP emissions in

this country. This overly narrow statutory interpretation also infects the agency’s

ability to tailor its regulation of EGUs by investigating other viable regulatory

programs on a cost-benefit basis.

A.

EPA’s Definition of “Appropriate” is Impermissibly Broad

EPA broadly defines the factors it may consider in determining whether

regulation under section 112(n)(1)(A), far more broadly than it did in the 2005

Revision.89 Under the proposed rule, EPA roams far afield from what should be the

central consideration as to whether regulation is “appropriate,” which is whether

EGU emissions of HAPs create “hazards to public health.” First, EPA states that,

“we interpret the statute to authorize the Agency to base the appropriate finding on

either hazards to public health or the environment.”90 The agency then goes on to

explain that the “appropriate” inquiry may be based and expanded beyond impacts

to the environment to also include HAP emissions from other sources. “The hazard

to public health or the environment may be the result of HAP emissions from EGUs

alone or the result of HAP emissions from EGUs in conjunction with HAP emissions

from other sources.”91 Lastly, the agency believes the “appropriate” prong may

also consider the impacts of HAPs internationally, which “would allow the U.S. to

demonstrate effective technologies to reduce Hg; such leadership could provide

confidence to other countries that they can succeed in meeting their

commitments.”92 Indeed, it appears as if EPA believes it has the discretion to base

89

On March 29, 2005, EPA concluded its rulemaking under section112. EPA concluded that “[b]ecause this

new information demonstrates that the level of Hg emissions projected to remain ‘after the imposition of’ section

110(a)(2)(D) does not cause hazards to public health, we conclude that it is not appropriate to regulate coal-fired

Utility Units under § 112 on the basis of Hg emissions.” 70 Fed. Reg. 16,004.

App.302

this determination on some broader set of criteria not contemplated by Congress

under section 112(n). It does not.

EPA grounds this expansive and sweeping interpretation in the belief that

Congress implicitly authorized EPA to treat these other factors at least on par with

public health hazards because it was authorized to consider these other factors in

the Mercury Study pursuant to § 112(n)(1)(B) and the National Academy of

Sciences (“NAS”) Study in § 112(n)(1)(C). This is a distortion of the statutory

language. Nowhere in section 112(n)(1)(A) does the term “environmental effects”

appear nor does (n)(1)(A) require EPA to even consider the results of the Mercury

Study or NAS Study prior to determining whether or not it is appropriate and

necessary to regulate. Furthermore, on the face of subparagraph (n)(1)(B), the

agency was not even required to complete the Mercury Study until one year after

Congress directed the EPA to complete the Utility Study. EPA’s interpretation is

without merit.

The interpretation in the 2005 Revision aligns much more closely with the

statutory language than the interpretation proffered by the proposed rule or in the

2000 determination. EPA stated in 2005, “[t]his mild direction [mercury study],

when paired with the considerable discretion inherent in any judgment about

whether an action is “appropriate and necessary,” has led EPA to conclude that the

statute permits the agency to consider other relevant factors when determining

whether to regulate emissions from utility units under section 112;” however the

agency confines this consideration by noting that “…these factors may not

independently, or in conjunction with one another, justify regulation under section

112(n) when EPA has concluded that hazards to U.S. public health are not

reasonably anticipated to occur.”93 Thus, EPA cannot conclude that it is authorized

to override the primary inquiry from Congress—i.e. hazards to public health

reasonably anticipated to occur from EGUs.

The 2005 Revision goes on to cite the U.S. Supreme Court’s holding in

Russello v. United States,94 that “where Congress includes particular language in

one section of a statute but omits it in another section of the same Act, it is

generally presumed that Congress acts intentionally…in the disparate inclusion or

exclusion.”95 Thus, if Congress had meant for the agency to make an “appropriate”

finding based on environmental factors, emissions from other source categories,

and in support of international efforts, it would not have gone to such great lengths

to include this particular provision in the CAA. Rather, Congress would have

directed the agency to list EGUs under § 112(c) from the outset and promulgate

MACT standards under section 112(d).

App.303

The underlying question in this exercise of statutory construction is why EPA

needs to impermissibly expand the inquiry—hazards to public health—and confer

great weight to and base its determination on this broader set of criteria to validate

its “appropriate” finding. Again, and as detailed above, the overall accredited

benefits to mercury reduction are particularly telling. Because the HAP of “greatest

concern” derives so little health benefit from command-and-control regulation, the

agency must use these other factors in an unlawful attempt to overcome the

irrefutable fact that HAP emissions from EGUs pose little or no threat to public

health. EPA’s regulation of mercury under section 112(d) is clearly contrary to the

statutory scheme developed by Congress.

To ameliorate this criticism, of heavy regulation for little environmental

benefit, EPA invokes the U.S. Supreme Court’s decision in Massachusetts v. EPA for

the proposition that even if the benefits of regulating are negligible, EPA still must

promulgate standards under section 112. This decision is inapposite of the facts at

issue in this rulemaking.

Whereas in Massachusetts the Supreme Court rejected the EPA’s use of

“policy considerations” as a shield to deny a rulemaking petition urging the agency

to regulate GHG emissions from new automobiles,96 the agency in this setting is

attempting to use the very same “policy considerations” as a sword for regulating

HAP emissions from EGUs. In rejecting EPA’s then-position, the Court emphasized

that the agency may not rest its decision to regulate or not to regulate on

“reasoning divorced from the statutory text.”97 Again, the fact that EPA must

highlight international efforts as a basis for regulation further illustrates its lack of

proper legal and factual support under in § 112(n)(1)(A).

B.

EPA’s “Necessary” Finding is Overly Narrow and Does Not

Comport with Congressional Intent

In contrast to EPA’s impermissibly broad reading of the “appropriate” prong,

the agency’s “necessary” interpretation is so arbitrarily narrow that it clearly

contravenes the intent of the statute. Moreover, it provides another example of the

agency exacting the highest level of stringency on a particular source when the

facts support a more reasonable approach. This interpretation renders the entire

section 112(n)(1)(A) analysis superfluous.

EPA claims the only programs under the CAA that qualify under the

necessary prong are those that “guarantee” emissions reductions directly from

EGUs. The agency states that “[w]e may find it necessary to regulate EGUs under

section 112 even if we were to conclude, based on reasonable estimations of

emissions reductions, that the imposition of the CAA would, or might, significantly

reduce the identified hazard, because the only way to guarantee that such

App.304

reductions will occur at all EGUs and be maintained is through a section 112(d)

standard that directly regulates HAP emissions from utilities.”98

Requiring this level of scrutiny is not what Congress envisioned when it

carved EGUs out of the normal section 112 regulatory scheme. Indeed,

Representative Oxley noted that “…if the Administrator regulates any of these

units, he may regulate only those units that he determines—after taking into

account compliance with all other provisions of the CAA and any other federal,

state, or local regulation and voluntary emission reductions—have been

demonstrated to cause a significant threat of adverse effects on public health.”99

Clearly, Congress was more concerned with the actual impact to public health and

whether those impacts were being addressed by any level of government, rather

than only crediting “guaranteed” federal command-and-control efforts.

According to the proposed rule, the only program under the CAA that falls

within the ambit of the necessary analysis is the Acid Rain Program (“ARP”). EPA

notes that the ARP qualifies because it contained very specific emissions reduction

requirements to be completed during a tight compliance timeframe. Importantly,

the actual implementation of those emission targets was largely left to the

individual utility where “source owners or operators could elect to install controls,

such as scrubbers, switch to lower sulfur fuels at their facilities or purchase

allowances from other EGUs that had reduced their emissions beyond what they

were required by the ARP to achieve.” 100

By comparison, EPA established a similar program with the promulgation of

the Clean Air Interstate Rule (“CAIR”) pursuant to section 110(a)(2)(D)(i)(I). CAIR

required a number of eastern states to develop State Implementation Plans

(“SIPs”) providing for substantial reductions of SO2 and NOx emissions largely

through the same implementation scheme as ARP—installation of scrubbers, SCRs

or purchasing allowances. In the 2005 Revision, EPA at least inherently recognized

the similarity, and accordingly, analyzed CAIR’s impact and concluded that “that the

technologies that most cost-effectively achieve SO2 and NOx reductions for utilities

are scrubbers for SO2 and SCR for NOx. These technologies, as noted above, result

in reductions of utility Hg emissions.”101

The proposed rule likewise acknowledges the 2005 Revision’s CAIR analysis,

but simply concludes that CAIR was remanded back to the agency in North Carolina

v. EPA with no further discussion. While CAIR was remanded by the D.C. Circuit,

the court allowed it to remain in place until the agency finalized its successor—

CSAPR. Like CAIR, CSAPR primarily addresses emissions from EGUs in 27 eastern

states. EPA claims that CSAPR will require a reduction of SO2 from EGUs by 73

percent from 2005 levels and 54 percent for NOx emissions. NMA contends that

the consideration of the achievements of CAIR and its successor should not have

ended with this conclusory statement.

Notwithstanding the similarities between CAIR/CSAPR and ARP, EPA does

not include these programs within its necessary analysis. The agency claims that it

is reasonable to exclude these programs by interpreting the phrase “after the

imposition of the Act” as only requiring “consideration of those requirements that

Congress directly imposed on EGUs through the CAA as amended in 1990 and for

which EPA could reasonably predict emissions reductions at the time of the Utility

Study.”102 Had Congress intended this reading it would have specified in

subparagraph (n)(1)(A) “…after the imposition of the requirements of Title IV of

this chapter,” but it did not. NMA can find no legal or factual basis in support of

this conclusion because Congress clearly appreciated the numerous programs, not

just the ARP, which EGUs and other sources would be subject to with the

amendments to the CAA. Hence the reason for § 112(n)(1)(A). EPA’s conclusion

here is fundamentally flawed and cannot withstand judicial scrutiny.

Returning to the appropriate analysis, EPA is willing to supplement the record

with new information to support its 2000 “appropriate” determination; however, the

agency refuses to do the same record augmentation in its “necessary” analysis.

EPA cannot have it both ways, especially after it already considered CAIR’s impact

in the 2005 Revision.103 As an aside, EPA conveniently cites CAIR in the proposed

rule as a prime example of utilities “engaging in forward planning” to support its

assertion that the necessary controls can be added within the MACT timeframe, but

is quick to minimize the same program’s benefits in other analyses within the same

rule.

Lastly, EPA’s discounting of the considerable achievements in air quality

through the NAAQS program is particularly puzzling. After engaging in a series of

shoulder-shrugging exercises, the agency concludes that the NAAQS program

cannot be factored into the necessary analysis because “EPA cannot predict with

any certainty precisely how states will ensure that the reductions needed to meet

the NAAQS will be realized.”104 This conclusion is suspect for at least two reasons.

First, EPA does in fact have the legal authority under section 110 of the CAA to find

that a state implementation plan is substantially inadequate to attain or maintain

the NAAQS, also known as a “SIP Call.” After receiving the SIP Call, if the named

state fails to complete a SIP revision or if EPA disapproves of such a revision, such

See Nat’l Cable & Telecommunication Ass’n v. Brand X Internet Services, 545 U.S. 967, 981 (2005) where

supported by a rational explanation for the deviation. EPA has not done so in this instance.

a finding will trigger clocks for mandatory sanctions and an obligation for EPA to

impose a Federal Implementation Plan (“FIP”). Thus, EPA clearly has the authority

to hold states accountable if the NAAQS program is not being administered

properly. Doubts about the implementation of the NAAQS program is not a

compelling argument for excluding those benefits from the necessary analysis.

C.

EPA is Not Compelled to Regulate EGUs under a MACT Standard

EPA mistakenly believes that once a positive appropriate and necessary

finding has been made, the agency has no choice but to list the source and

promulgate MACT standards for mercury and all HAPs under section 112(d) despite

never attempting to make a health-based finding for the other non-mercury HAPs.

NMA does not concur with this statutory interpretation.105 Indeed, a correct reading

of the regulatory language under § 112(n)(1)(A) provides EPA with the opportunity

to develop a properly tailored regulation achieving environmental benefit

commensurate with the cost.

Assuming arguendo that EPA has adequately determined it is both

appropriate and necessary to regulate mercury emissions from utilities, the

statutory phrase “under this section” evinces the intent of Congress that a positive

finding for mercury does not automatically subject EGUs to a MACT standard under

section 112(d). Nowhere in section 112(n)(1)(A) is EPA directed or compelled to do

this. By comparison, section 112(c)(2) does specifically compel that “the

Administrator shall establish emissions standards under subsection (d) of this

section.” (emphasis added). Therefore, had Congress wanted EGUs to be

specifically regulated under § 112(d) following the appropriate and necessary

determination, it would have so directed.

Additionally, the CAA directs EPA to develop and describe “alternative control

strategies for emissions which may warrant regulation under this section.” This

language leaves little doubt that Congress contemplated other regulatory options

other than the MACT option the agency mistakenly believes it is compelled to

observe. Furthermore, in developing these alternative control strategies, EPA can

and should consider the cost of control technology. Despite EPA’s protestations to

the contrary, the comparison of alternative control strategies necessarily implies

cost. Interestingly, and with a far less compelling invitation to inject environmental

concerns into the appropriate analysis, the agency steadfastly maintains that

Congress did not contemplate cost as a basis for regulatory comparison. “Finally,

105

As the D.C. Circuit has made clear, an “agency regulation must be declared invalid,’” even though the

agency “might be able to adopt the regulation in the exercise of its discretion,’” if the regulation “was not based on

the [agency’s] own judgment’” but “rather on the unjustified assumption that it was Congress’ judgment that such

[a regulation] is desirable ‘or required.” See Transitional Hospitals Corp. v. Shalala, 222 F. 3d 1019, 1029 (D.C. Cir

2000), quoting Prill v. NLRB, 755 F.2d 941, 948 (D.C. Cir. 1985).

-43-

App.307

significantly, nowhere in section 112(n)(1)(A) does Congress require the

consideration of costs in assessing health and environmental impacts.”106

This flatly distorts the statutory language. In fact, Representative Oxley

stated that “[t]he conference committee produced a utility air toxics provision that

will provide ample protection of the public health while avoiding the imposition of

excessive and unnecessary costs on residential, industrial and commercial

consumers of electricity.”107 Moreover, EPA’s argument is legally deficient as the

D.C. Circuit in Michigan v. EPA held “[i]t is only where there is ‘clear congressional

intent to preclude consideration of cost’ that we find agencies barred from

considering costs.”108 Consequently, when viewed through the lens of heavy

regulatory burdens for little to no incremental health benefit, the agency should

promulgate alternative control strategies to deal with an issue with little impact to

public health. Without such an approach the agency employs a blunt hammer in a

situation begging for the precision of a sharp scalpel.

EPA’s argument that the CAA requires MACT standards for all HAPs based on

a positive mercury predicate finding is equally misguided. As stated previously, at

no point in EPA’s consideration of this issue has it made an affirmative health-based

finding for any HAP other than mercury.

The agency’s attempt to shoehorn the D.C. Circuit’s decision in National Lime

to support this conclusion is also unavailing. In that case, the court’s decision

turned on language of § 112(d)(1) rather than the subsection at issue in the instant

rulemaking. Since EGUs were purposefully omitted from that section by Congress,

the decision has limited persuasive value under the present circumstances.

Moreover, EPA claims it is still appropriate to regulate non-mercury HAPs

because “emissions of these HAP from some EGUs pose a cancer risk greater than

one in one million to the most exposed individual.”109 EPA is attempting to use the

delisting criteria in § 112(c) to obfuscate the proper statutory analysis. For EGUs,

the delisting criteria are not applicable until
