U.S. Environmental Protection Agency

RE: Request for Agency Stay Pending Review of Interim Final Rule Establishing

Nonconformance Penalties for On-Highway Heavy Heavy-Duty Diesel Engines

Dear Administrator Jackson:

We are writing on behalf of Daimler Trucks North America LLC (“DTNA”) and Detroit Diesel

Corporation (“DDC”), pursuant to Federal Rule of Appellate Procedure 18(a), to request that the U.S.

Environmental Protection Agency (“EPA”) stay its Interim Final Rule, signed January 20, 2012 and

published January 31, 2012, pending judicial review.1 DTNA and DDC intend to file a petition for

review of the Interim Final Rule in the United States Court of Appeals for the District of Columbia

Circuit pursuant to the Clean Air Act, 42 U.S.C. §§ 7401-7671q (“CAA”). Federal Rule of Appellate

Procedure 18(a) provides that, before moving for a stay of agency action in the Court of Appeals, a

petitioner must ordinarily move first before the agency for a stay pending review of its action.

Accordingly, DTNA and DDC request that EPA stay its Interim Final Rule. If DTNA and DDC have

not received a response within 10 days of the date of this letter, we will assume that EPA has denied

our request for stay pending review pursuant to Federal Rule of Appellate Procedure 18(a).

I. Background

On January 20, 2012, EPA announced its decision to establish nonconformance penalties

(“NCPs”) for oxides of nitrogen (“NOx”) emissions from on-highway heavy heavy-duty diesel

engines. EPA issued an Interim Final Rule, effective as of January 31, 2012, establishing NCPs for

model years 2012 and 2013. At the same time, EPA issued a Notice of Proposed Rulemaking

proposing essentially identical NCPs for heavy heavy-duty engines, but also including proposed

NCPs for medium heavy-duty engines, which would supersede the interim NCPs upon issuance of

the final rule, which is expected no sooner than late in 2012. Although EPA is accepting comments

on the NCP rulemakings until April 4, 2012, any comments received will be considered “in the

1

The Interim Final Rule entitled “Nonconformance Penalties for On-Highway Heavy Heavy-Duty Diesel

Engines” was signed and announced on January 20, 2012 and published in the Federal Register at 77

Fed. Reg. 4,678 on January 31, 2012. At the same time, EPA announced a Notice of Proposed

Rulemaking, which was published in the Federal Register at 77 Fed. Reg. 4,736 (Jan. 31, 2012).
- 2 - February 2, 2012

context of the accompanying notice of proposed rulemaking” and will not affect the Interim Final

Rule, which was issued without notice or opportunity for comment before it became effective. See

77 Fed. Reg. 4,678, 4,680 (Jan. 31, 2012).

NCPs are intended to provide a limited exception to meeting regulatory emissions standards

where EPA finds that the regulatory lead time it has provided is insufficient to enable manufacturers

to develop the technology necessary to meet the standards. By paying NCPs, such manufacturers

are allowed, on a limited basis, to produce and sell engines that do not comply with the standard.

Congress recognized that an escape valve is desirable under certain limited circumstances where

the required technology does not yet exist, so that technological laggards are not immediately forced

out of the marketplace when EPA issues more stringent standards.

The Clean Air Act permits EPA to establish NCPs within certain specified statutory limits.

First, EPA must promulgate regulations governing NCPs “after notice and opportunity for public

hearing.” CAA § 206(g)(1), 42 U.S.C. § 7525(g)(1). EPA must set an emissions “upper limit,” or

percentage determined to be “practicable,” above which no engine may be certified, even through

the manufacturer’s payment of NCPs. CAA § 206(g)(2), 42 U.S.C. § 7525(g)(2). EPA must also

establish a formula by regulation for determining the amounts of NCPs. CAA § 206(g)(3), 42 U.S.C.

§ 7525(g)(3). Under this formula, the penalties must: (1) “take into account the extent to which

actual emissions of any air pollutant exceed allowable emissions under the standards”; (2) “be

increased periodically in order to create incentives for the development of production vehicles or

engines which achieve the required degree of emission reduction”; and (3) “remove any competitive

disadvantage to manufacturers whose engines or vehicles achieve the required degree of emissions

reduction.” Id.

By regulation, EPA has specified certain additional criteria that must be met for EPA to

establish the availability of NCPs and set an NCP amount for a given emission standard. See 40

C.F.R. § 86.1103-87. First, there must be a new or revised emission standard that is more stringent

than the previous standard for the pollutant, or the existing standard for the pollutant must become

more difficult to achieve because of a new or revised standard. 40 C.F.R. § 86.1103-87(a). Second,

EPA must find that substantial work will be required to meet the emission standard. 40 C.F.R.

§ 86.1103-87(a)(1). Substantial work is defined as “the application of technology not previously

used in an engine or vehicle class or subclass, or the significant modification of existing technology

or design parameters, needed to bring the vehicle or engine into compliance.” 40 C.F.R. § 86.1103-

87(b). Third, EPA must find that there is likely to be a technological laggard, 40 C.F.R. § 86.1103-

87(a)(2), which EPA has explained is “a manufacturer who cannot meet the emission standard due

to technological (not economic) difficulties and who, in the absence of NCPs, might be forced from

the marketplace, including the elimination of one or more engine families/configurations from

production.” 67 Fed. Reg. 51,464, 51,465 (Aug. 8, 2002).

EPA has established NCPs applicable to heavy-duty diesel engines only five times over the

past 27 years, since it issued its generic “Phase I” regulations setting out the framework and formula

for NCPs in 1985. In 1985, EPA set NCPs for particulate matter and NOx emissions for model year

1988. In 1990, EPA set NCPs for NOx for model year 1991. In 1993, EPA set NCPs for particulate

matter for model year 1994. In 1996, EPA set NCPs for NOx for model year 1998. Most recently, in

2002, EPA set NCPs for non-methane hydrocarbon plus NOx emissions for model year 2004. Now,

in 2012, EPA is establishing NCPs for the heavy-duty diesel NOx emission standard, which was

promulgated in 2001, was phased in beginning in 2007, and became fully effective in 2010.

When EPA sets NCP amounts, it must gather cost data from manufacturers in order to

determine the costs of compliance with the emission standard and ensure that it removes “any

competitive disadvantage” to complying manufacturers. See CAA § 206(g)(3)(E), 42 U.S.C.
- 3 - February 2, 2012

§ 7525(g)(3)(E). From these data, EPA is able to derive various factors and inputs necessary to

calculate the appropriate penalty amount, so that any competitive disadvantage to complying

manufacturers is removed. In the past, EPA has requested information in writing from engine

manufacturers, proposed the values for a new NCP for a given emission standard with proper public

notice, accepted comments from the manufacturers and other members of the public, revised its

proposal accordingly, and then issued its final rule. In this case, EPA contacted various engine

manufacturers via telephone in late 2011 requesting preliminary information for a proposed NCP

rulemaking but did not take written submissions and refused requests for additional meetings with

individual manufacturers. Without prior notice, EPA then issued its Interim Final Rule establishing

NCP values much lower than the preliminary cost estimates it had received from DTNA and DDC—

effective immediately.

In its Interim Final Rule, EPA admits that, although any manufacturer may use these NCPs,

they were established to benefit one manufacturer. After using credits to certify its engines rather

than meeting the 2010 NOx standard for more than two years, this manufacturer “notified [EPA] late

in 2011 that it would not have enough emissions credits for its model year 2012 heavy heavy-duty

engines.” 77 Fed. Reg. at 4,679. This same manufacturer—not named by EPA but known to be

Navistar, Inc.—filed multiple lawsuits against EPA in 2009, in part challenging the 2010 NOx

standard as infeasible. The NOx standard was set through rulemaking in 2001, was phased in

beginning in 2007, and became fully effective in 2010. In 2001, several different technologies were

considered by EPA and heavy-duty diesel engine manufacturers to have the potential to meet the

stricter 0.2 gram per brake horsepower-hour NOx standard. Over the course of the next six to eight

years, as manufacturers utilized the lead time provided by EPA, it became clear that only selective

catalytic reduction (“SCR”) technology was capable of meeting the 0.2 g/bhp-hr NOx standard.

While the rest of the industry adopted SCR technology, Navistar committed itself to using only

exhaust gas recirculation (“EGR”) to meet the 0.2 g/bhp-hr NOx standard. Since then, Navistar has

waged a media campaign against its competitors’ SCR technology, and filed another set of lawsuits

in 2011 against the California Air Resources Board and EPA, seeking to subject its competitors’

SCR-equipped engines to unwarranted testing requirements in an effort to force the recall of their

engines. All the while, Navistar has failed to produce an engine capable of meeting the 0.2 g/bhp-hr

NOx standard.

In response to Navistar’s belated notice that it would not have enough emissions credits for

the 2012 model year, EPA acted hastily and announced its Interim Final Rule on January 20, 2012,

providing no notice or opportunity for comment. In its Notice of Proposed Rulemaking, announced at

the same time, EPA acknowledges the many ways in which the current NCP process and calculation

differs from EPA’s prior rules, and requests comments on many of the flaws in its current approach.

Given its many flaws, DTNA and DDC respectfully request that the agency stay its Interim Final

Rule.

II. Factors Supporting Request for Stay

Under the Administrative Procedure Act, EPA has authority to postpone the effective date of

a rule pending judicial review when it finds that “justice so requires.” 5 U.S.C. § 705. Even under

the rubric that Article III courts use to evaluate a stay, the Interim Final Rule should be put on hold

pending review. That rubric dictates that a court stay an agency rule when: (1) the movant is likely

to prevail on the merits; (2) the movant will suffer irreparable harm absent a stay; (3) the adverse

party will suffer no substantial harm from the issuance of a stay; and (4) the public interest will be

served by granting a stay. Wis. Gas Co. v. FERC, 758 F.2d 669, 673-74 (D.C. Cir. 1985). All four

factors weigh in favor of a stay of EPA’s Interim Final Rule pending review by the D.C. Circuit Court
- 4 - February 2, 2012

of Appeals.2 Accordingly, DTNA and DDC request that EPA stay the Interim Final Rule and

postpone the availability of nonconformance penalties until the proposed rulemaking is finalized

through public notice-and-comment and proper consideration of comments received, or until the

Interim Final Rule is upheld by the D.C. Circuit.

A. DTNA and DDC Are Likely to Prevail on the Merits

DTNA and DDC intend to petition for review of the Interim Final Rule on the basis that EPA

has taken actions that are arbitrary, capricious, an abuse of discretion, or otherwise not in

accordance with law. DTNA and DDC are likely to prevail for at least three reasons: (1) EPA has not

met the legal criteria required by its own regulations for establishing NCPs; (2) EPA has not

complied with the statutory requirements for establishing NCPs under the Clean Air Act; and (3) EPA

has unlawfully issued an Interim Final Rule without prior notice and opportunity for comment.

1. EPA Has Not Met the Legal Criteria Required by Its Own Regulations

NCPs are not to be granted lightly. And the Agency’s regulations reflect that, imposing

stringent triggers that will rarely be met. As we demonstrate below, EPA’s decision to establish the

NCPs here does not meet the three regulatory criteria. The Agency’s missteps share a common

denominator: there is nothing new and certainly nothing exigent that warrants this radical relief. The

NOx standard at issue here was issued more than a decade ago. During that time, every

manufacturer—save for Navistar—invested tens of millions of dollars to comply with EPA’s mandate

by using a well-proven technology. That Navistar chose a different route—one that has led to a

dead end so far—is no reason to change the rules now. NCPs should not be granted simply to

appease the idiosyncratic—and stubbornly wrong—choices of a single manufacturer in the industry.

a. There Is No New or Revised Emission Standard for 2012

Under EPA’s own regulations, an NCP may be set only “when any new or revised emission

standard is more stringent than the previous standard for the pollutant, or when an existing standard

for that pollutant becomes more difficult to achieve because of a new or revised standard.” 40

C.F.R. § 86.1103-87(a). Here, there is no new or revised NOx standard; the standard is the same

for 2012 as it was for 2010, and it was promulgated in 2001 with adequate notice to manufacturers.3

Further, there are no other new or revised standards that make the 2012 NOx standard more difficult

to achieve. In attempting to justify its Interim Final Rule establishing NCPs, EPA conveniently

ignores the fact that it is now 2012 and instead focuses on the fact that the 2010 NOx standard was

lower than the 2004 standard. See 77 Fed. Reg. at 4,681. EPA also states: “When promulgated

[i.e., in 2001], the Agency concluded that the 0.20 g/bhp-hr NOx standard was a technology forcing

standard.” Id. (emphasis added). EPA’s conclusion 11 years ago has no bearing on whether there

now exists a new or revised and more stringent emission standard applicable to the current model

year for which EPA seeks to set NCPs.

2

In setting forth this summary of the four factors weighing in favor of a stay, DTNA and DDC do not

intend to restrict their ability to assert additional arguments and reserve all rights to fully brief these and

any other legal arguments in the D.C. Circuit Court of Appeals.

3

All of EPA’s previous NCP rulemakings were conducted before or at the same time that the emission

standards were taking effect. Most were established one to two years before the standard became

effective—e.g., NCPs for the 2004 standards were promulgated in 2002, two years before the standards

become effective. It is now 2012, eleven years after the NOx standards were promulgated in 2001 and

two years after the NOx standard become effective. The regulatory provisions cannot reasonably be read

to allow for such a belated NCP determination.
- 5 - February 2, 2012

b. Substantial Work as Defined by EPA Is Not Required

Before establishing an NCP for a particular emission standard for a particular subclass of

heavy-duty engines, EPA must also find that “substantial work” will be required to meet the emission

standard. Substantial work is defined as “the application of technology not previously used in an

engine or vehicle class or subclass, or the significant modification of existing technology or design

parameters, needed to bring the vehicle or engine into compliance.” 40 C.F.R. § 86.1103-87(b).

EPA cannot find that substantial work is required to meet the 2010 NOx standard now that SCR has

been used—successfully—in heavy-duty diesel engines, including engines manufactured by

Navistar for other markets.4

This is not a close question. The rest of the industry was able to implement SCR in time to

meet the 2010 standard. Navistar faces a much easier time now that its competitors have done all

of the hard work for it, having developed both the technology and the necessary infrastructure for an

effective solution. EPA has recognized that this situation, where all engine manufacturers except

one have already met the standard, cannot justify a “substantial work” finding: “Obviously,

substantial effort would not be required if many manufacturers’ vehicles/engines were already

meeting the revised standard or could do so with relatively minor calibration changes or

modifications.” 50 Fed. Reg. 35,374, 35,403 (Aug. 30, 1985) (emphasis added). While substantial

work was required before model year 2010, it can no longer be said to be needed in 2012, two years

after SCR was implemented in the same class of engine by every other manufacturer in the industry.

For EPA to insist otherwise gets the regulatory analysis backwards. That freewheeling approach

would justify NCPs any time new technology is used to meet an emission standard—a result

Congress surely did not intend under the Clean Air Act.

c. There Is No Technological Laggard

In addition to finding that substantial work will be required, EPA must also find that there is

likely to be a technological laggard before establishing an NCP for a particular emission standard.

The emphasis is very much on the adjective “technological”; not just any laggard will do. As the

Agency has noted, a technological laggard is “a manufacturer who cannot meet the emission

standard due to technological (not economic) difficulties and who, in the absence of NCPs, might be

forced from the marketplace.” 67 Fed. Reg. 51,464, 51,465 (Aug. 8, 2002) (emphasis added).

The distinction between true technological laggards and economic laggards—particularly

those who have intentionally impoverished themselves—is critical here. As one federal court has

held, “NCPs were intended to give a manufacturer that has made every effort to comply, but has

been unable to achieve compliance, a chance to continue to participate in the market.” United

States v. Caterpillar, Inc., 227 F. Supp. 2d 73, 88 (D.D.C. 2002) (emphasis added). That is exactly

what this Agency has said before as well: “An emission standard may become more difficult to meet

and substantial work may be required for compliance, but if that work merely involves transfer of

well-developed technology from another vehicle class, it is unlikely that a technological laggard

would develop.” 67 Fed. Reg. at 51,465 (emphasis added).

That is precisely this case. It is undisputed that SCR is a proven technology adopted by the

rest of the industry. It is likewise undisputed that Navistar has failed to demonstrate that it cannot

4

See MWM International Press Release, http://www.navinternational.com.br/default.asp?su=7&pa=

detalhes&fo=releases&id=82 (Nov. 22, 2006) (indicating that Navistar’s wholly owned subsidiary MWM

International “has opted to use SCR system for heavy applications, such as trucks” in Brazil); see also

Navistar MaxxForce 9.3H Engine Brochure (using SCR aftertreatment to meet Euro V emission

standards).
- 6 - February 2, 2012

use SCR. To the contrary, Navistar’s wholly owned subsidiary is already using SCR in Brazil. What

that means is that Navistar purposefully chose not to use SCR in the United States, thinking it could

gain some economic or competitive advantage.5 But EPA need not delve into Navistar’s subjective

reasons for refusing to do what every other manufacturer in the industry diligently did to comply.

Instead, it is enough to recognize that the work involved in meeting the 2010 NOx standard now

merely involves the transfer of well-developed technology. From that indisputable premise, only one

conclusion follows: EPA cannot find that a technological laggard exists.

To the extent EPA considered this factor, it offered an ill-fitting justification. According to

EPA, Navistar is a “technological laggard” because it “intends to use a different technology to meet

the NOx standard . . . . Since it has not yet submitted an application for certification for any model

year 2012 heavy heavy-duty diesel engines that would not require emission credits, we believe it is a

reasonable possibility that [Navistar] may not be able to comply for technological reasons with

respect to the 2010 NOx standards for heavy heavy-duty diesel engines in the 2012 and 2013 model

years.” 77 Fed. Reg. at 4,681. Navistar has used credits to sell its engines since the 0.2 g/bhp-hr

NOx standard became fully effective in 2010 and continues to maintain a NOx credit balance into

2012. All along, Navistar has publicly promised its investors, dealers, and customers that it has a

0.2 g/bhp-hr compliant engine ready for certification and production. In fact, Navistar submitted

certification data for a 0.2 g/bhp-hr engine to EPA on January 31, 2012—the same day that the

Interim Final Rule was published in the Federal Register and the NCPs took effect.6 Accordingly, a

critical factual predicate of the Agency’s rulemakings has been proven incorrect on the same day

that it published its no-comment rulemaking in the Federal Register. That alone is good cause to

stay the Interim Final Rule. But Navistar’s recent disclosures provide even more support for staying

the rulemaking.

Specifically, Navistar has an engine that can meet the 2010 NOx standard, but according to

its Senior Vice President of North American Sales Operations: “‘[W]e can’t get optimum

performance’ in fuel economy, and executives don’t want to release the engine for sale, Hebe said.

Tests show the point-2 engine, a 12.4-liter Maxx Force 13, gets fuel economy as good as the current

model, but execs want it to be better. Drivers and owners ‘won’t see the difference’ in the point-2

engine’s performance if they used it as it now is, because there are no equipment changes, he said.

The lower NOx emissions can be achieved with modified fuel pressures, altered introduction of inlet

air, and recalibration of electronic controls.”7 Navistar’s own public statements demonstrate that it

has intentionally chosen not to meet the 2010 NOx standard due to concerns about fuel economy—a

factor completely irrelevant to a determination by EPA of whether NCPs are warranted. Navistar

admits that it is not a technological laggard and that it does not now require “substantial work” for it

finally to comply with the 2010 NOx standard. Thus, Navistar has a choice of two technology paths

for compliance: the EGR technology solution it has promoted as capable of meeting the standard for

years; or the SCR technology proven by the rest of the industry in use for more than two years. The

indisputable existence of either engine technology makes it impossible for EPA to conclude that

there is a technological laggard, or that “substantial work” is still required. There is simply no basis

to conclude that Navistar is anything other than an intentional economic laggard who made a

business decision to cling to EGR technology and use credits to sell otherwise noncompliant engines

until its credits ran out and it was forced to produce a compliant 0.2 g/bhp-hr engine.

2. EPA Has Not Complied with the Statutory Requirements for Establishing NCPs

Under the Clean Air Act

The Clean Air Act mandates that any NCP set by EPA must “remove any competitive

disadvantage to manufacturers whose engines or vehicles achieve the required degree of emissions

reduction.” CAA § 206(g)(3)(E), 42 U.S.C. § 7525(g)(3)(E). EPA has failed to meet this statutory

obligation. The NCP amount set by EPA in the Interim Final Rule comes nowhere near

approximating the true cost of producing an engine that is compliant with the 2010 NOx standard.

EPA is requiring Navistar to pay a maximum of $1,919 per engine to continue selling engines that

pollute at more than double the standard. DTNA and DDC informed EPA that it costs DDC many

times that much per engine for the additional hardware necessary to meet the 2010 NOx standard.

This information does not even include lost market share or the additional warranty costs that have

been recognized by EPA previously as important cost factors. EPA’s current figure is also a fraction

of the $12,210 penalty it established for the same degree of NOx exceedance for the 2004 NOx

standard, which was EPA’s most recent prior rule on NCPs for heavy-duty diesel engines.8 Unlike

the 2010 NOx standard, which to date has required a new type of emissions control technology, the

entire industry met the 2004 NOx standard using in-cylinder emissions control strategies that had

already been developed. EPA has provided no explanation of why the current standards, which to

date have only been met by using new SCR technology, are not more costly than the NCPs for the

2004 NOx standard. Of course, EPA would not take written submissions and refused requests for

additional meetings, saying that it was simply gathering preliminary information for a proposed NCP

rulemaking. Even so, EPA came out with a figure that is a small fraction of the figures presented by

complying manufacturers in the preliminary discussions.

EPA’s figure does not adequately reflect the actual costs of incorporating compliant

technology, in large part because it assumes a baseline engine that already has SCR technology in

place. But Navistar does not already have SCR technology in place on its U.S. engines, and neither

did the complying manufacturers when the standard was promulgated in 2001. The complying

manufacturers invested in the research and development, hardware components, software,

infrastructure, and other advancements necessary to design and produce engines that are actually

compliant with the 2010 NOx standard—investment that Navistar has thus far failed to make. It is

unreasonable, and unfair, to give Navistar the benefit of assuming a baseline engine that

incorporates the very technology that Navistar has chosen not to adopt.

8

See EPA, Regulatory Announcement: Nonconformance Penalties for Heavy-Duty Diesel Engines

(August 2002).
- 8 - February 2, 2012

In fact, the NCP level is so low that Navistar’s competitors will be forced to consider

manufacturing engines that do not meet the NOx standard in order to take advantage of the

competitive advantage afforded by the below-market NOx NCP. The legislative history makes clear

that this was not the intent behind the NCP provision: “The Committee does not intend to encourage

non-compliance with the revised standards. For example, if a manufacturer opts to pay the penalty

and to design or tune the vehicle or engine to higher emission levels, the nonconformance penalty

would probably be inadequate and should be revised.” H.R. Rep. 95-294, at 276 (1977). The NCP

regulations do not give EPA the option of providing NCPs for one manufacturer and not the others.

The only solution is to ensure that the NCP penalty is high enough to encourage full compliance with

the NOx standard.

By assuming a baseline engine with SCR technology and factoring in only the incremental

costs associated with adjusting that SCR technology from a 0.50 to a 0.20 g/bhp-hr NOx emission

level, EPA has completely vitiated the NCP calculation and the intent of the Clean Air Act. Given

proper notice and opportunity for comment, the complying manufacturers could have provided EPA

with the necessary information to enable it to set an NCP that removed any competitive

disadvantage, as required under the Clean Air Act. As it stands now, EPA’s Interim Final Rule must

be vacated due to EPA’s failure to fulfill its statutory mandate to remove any competitive

disadvantage to complying manufacturers.

3. EPA Unlawfully Issued the Interim Final Rule Without Prior Notice and

Opportunity for Comment

Finally, DTNA and DDC are likely to succeed on the merits because EPA improvidently

issued the NCP Interim Final Rule without any notice-and-comment period. See CAA § 206(g)(1),

42 U.S.C. § 7525(g)(1) (NCP regulations may only be “promulgated by the Administrator after notice

and opportunity for public hearing”). EPA purported to excuse that procedural shortcut by invoking

section 553(b)(B) of the Administrative Procedure Act. But that narrow provision does not offer the

Agency unfettered discretion to exempt itself from orderly rulemaking at its whim. Just the opposite.

Congress provided that safety valve for truly extraordinary cases where notice and comment would

be “impracticable, unnecessary, or contrary to the public interest.” 5 U.S.C. § 553(b)(B). Because

EPA has failed to offer a rational explanation for its unprincipled departure from orderly rulemaking,

the Agency should grant a stay until the D.C. Circuit can review its decision.

And there is little doubt how the D.C. Circuit will resolve the claim. Time and again, that

court has held that “the various exceptions to the notice-and-comment provisions of section 553 will

be narrowly construed and only reluctantly countenanced.” New Jersey v. EPA, 626 F.2d 1038,

1045 (D.C. Cir. 1980) (emphasis added); accord Lake Carriers’ Ass’n v. EPA, 652 F.3d 1, 6 (D.C.

Cir. 2011); Util. Solid Waste Activities Grp. v. EPA, 236 F.3d 749, 754 (D.C. Cir. 2001). And for

good reason: the Administrative Procedure Act’s notice-and-comment requirement “was one of

Congress’s most effective and enduring solutions to the central dilemma it encountered in writing the

APA[:] reconciling the agencies’ need to perform effectively with the necessity that ‘the law must

provide that the governors shall be governed and the regulators shall be regulated, if our present

form of government is to endure.’” Am. Bus Ass’n v. United States, 627 F.2d 525, 528 (D.C. Cir.

1980) (quoting S. Doc. No. 248, 79th Cong., 2d Sess. 244 (1946)). The exception “is not an ‘escape

clause’; its use ‘should be limited to emergency situations.’” Util. Solid Waste Activities Grp., 236

F.3d at 754 (quoting Am. Fed’n of Gov’t Emps. v. Block, 655 F.2d 1153, 1156 (D.C. Cir. 1981)).

EPA ignored these admonitions. Far from identifying any “emergency situations” that

warranted expedited rulemaking, the Agency pointed to a handful of workaday concerns. More

troubling still, the four rationales ginned up by EPA to justify its end-run around the notice-and-
- 9 - February 2, 2012

comment requirement are conclusory and impermissibly vague: (1) taking interim action avoids the

possibility of “an engine manufacturer”—Navistar—from being unable to certify a complete line of

products for model year 2012 and/or 2013; (2) the rule is only amending “limited provisions” in

existing NCP regulations; (3) the rule’s duration is limited; and (4) there is no risk to the public

interest in allowing manufacturers to certify using NCPs before the point at which EPA could make

them available through notice-and-comment rulemaking. 77 Fed. Reg. at 4,680. None of these

justifications is sufficient to salvage the Interim Final Rule.

a. First, EPA cannot waive notice-and-comment rulemaking simply because an individual

market participant—Navistar—may be harmed without the waiver. To the extent that Navistar will

have problems certifying a full range of model year 2012 and 2013 engines, it is a problem of

Navistar’s own making. Keep in mind that Navistar was well aware of the 2010 NOx emission

standard in 2001, when it was first adopted. Navistar was also aware that SCR technology was

available for Navistar to meet its 2010 NOx standard obligations, given that Navistar’s competitors

were spending millions developing it and incorporating it into their fleets. But the real punch line is

that even Navistar was using the technology—just overseas, not here in the United States. Yet

rather than rely on tried-and-true technology, Navistar made a bet. It bet that it could develop a

2010 NOx standard compliant engine without using SCR, and put its regulatory compliance down as

stakes.

That bet did not pay off. And that has been apparent since at least 2009, when Navistar

sought review in the D.C. Circuit of the 2010 NOx standard. Navistar v. EPA, No. 09-1113 (D.C. Cir.

2009). In that litigation, Navistar argued that the 2010 NOx standard was infeasible, in part because

its EGR technology would be unable to meet it. See Petitioner’s Final Opening Brief, at 30-31, 61,

Navistar v. EPA (No. 09-1113) (Apr. 5, 2010 D.C. Cir.) (“Navistar 2009 Brief”) (admitting that

Navistar invested in credits because it knew that it would be unable to comply with the 2010 NOx

standard and arguing that the 0.20 NOx standard should be repealed because it cannot be met).

EPA acknowledged that “Navistar’s EGR engines emit approximately 0.50g NOx, or over twice the

0.20g standard. As such, Navistar will only be certified as meeting the 2010 NOx requirements by

using banked credits.” Respondent’s Final Opposition Brief, at 29-30, Navistar v. EPA (No. 09-1113)

(Apr. 9, 2010 D.C. Cir.).9

EPA’s statement in the 2009 litigation is telling. It demonstrates that EPA was not only

aware that Navistar would not have a 2010 NOx compliant engine—something the whole industry

had known—but also that Navistar would be using credits to put its product line onto the market. It

shows, in other words, that EPA knew that Navistar was living on borrowed time. If EPA wished to

pursue NCPs as a way to allow Navistar to certify a full product line, it could have begun that

process then as it always has—through notice and comment before the emission standard took

effect. Instead, EPA allowed Navistar to gamble that it would be able to bring a 2010 NOx compliant

engine onto the market before its credits ran out, and bailed Navistar out with NCP penalties when

that gamble turned out to be a bust. In short, EPA used the APA’s waiver of notice and comment

provision as an escape clause to save Navistar from its own bad business choices. That is hardly

an emergency. See Util. Solid Waste Activities Grp., 236 F.3d at 754.

9 Of course, the 2009 litigation only represents the culmination of what must have been an understanding

for some time at Navistar that there would be no way for Navistar to comply with the 2010 NOx standard.

A manufacturer does not seek the relief that Navistar sought in that case—an order essentially forbidding

EPA from certifying any SCR engines and revoking the certificates of conformity issued to existing SCR

engines—lightly. See Navistar 2009 Brief, at 60 (demanding that the certificates of conformity issued for

model year 2010 SCR engines be revoked).
- 10 - February 2, 2012

Fundamentally, EPA’s rush to issue the Interim Final Rule is based on a deeply flawed

premise. It assumes that EPA has an obligation to ensure that Navistar is able to sell heavy heavyduty engines. See 77 Fed. Reg. at 4,680 (“[M]aking NCPs available through this Interim Final Rule

is the only way to ensure that the manufacturer’s depletion of NOx credits will not force it to cease

production of heavy heavy-duty engines this year.”). But the Agency’s mandate is not to coddle or

favor one manufacturer to the detriment of an entire industry that has diligently invested millions over

a decade to honor EPA’s mandate.

But even if EPA had some obligation to insulate Navistar from its own misguided decisions,

an impending deadline alone still would not allow the Agency to waive notice and comment

rulemaking. See Council of S. Mountains, Inc. v. Donovan, 653 F.2d 573, 581 (D.C. Cir. 1981).

That makes good sense. Were the rule otherwise, “an agency unwilling to provide notice or an

opportunity to comment could simply wait until the eve of a statutory, judicial, or administrative

deadline, then raise up the ‘good cause’ banner and promulgate rules without following APA

procedures.” Id. In fact, the D.C. Circuit has held that even where an interim rule was of “life-saving

importance,” allowing an exception to notice and comment rulemaking was an “extremely close”

question and only allowed “guardedly.” Id. at 581-82.

Here, of course, the Interim Final Rule is hardly of “lifesaving importance.” Rather, it is more

like the interim rule vacated in Union of Concerned Scientists v. Nuclear Regulatory Commission,

711 F.2d 370 (D.C. Cir. 1983). As the Court explained, “when the Commission incorporated

compliance deadlines into all operating licenses, it saddled itself with the burden of providing an

opportunity for public comment when it became necessary to change those deadlines.” Id. at 383.

Indeed, because the agency’s staff had known of the looming deadline for eleven months, yet did

not undertake notice and comment rulemaking, the agency’s decision to eliminate the notice and

comment opportunity was especially “egregious.” Id. at 382-83.

So too here. When EPA set the 2010 NOx compliance deadlines, “it saddled itself with . . .

providing an opportunity for public comment [if] it became necessary to change those deadlines.” Id.

at 383. EPA knew of Navistar’s impending depletion of its credits for much longer than eleven

months—it knew for over two years. That makes its failure to promptly propose rulemaking even

more egregious than in Union of Concerned Scientists. As the D.C. Circuit has explained, when “an

alleged ‘emergency’ arises as the result of the agency’s own delay, the claims . . . advanced by EPA

[regarding lack of necessity for notice and comment] are baseless.” Envtl. Def. Fund, Inc. v. EPA,

716 F.2d 915, 920-21 (D.C. Cir. 1983). EPA’s claims of emergency in the Interim Final Rule are

equally baseless.

b. EPA’s second justification—that issuing the NCP Interim Final Rule without notice and

comment is permissible because the rule “is only amending limited provisions in existing NCP

regulations,” 77 Fed. Reg. at 4,680—is both factually disingenuous and legally insufficient. It is

disingenuous because the Interim Final Rule does more than just tweak some small portion of the

existing regulations; it creates an entirely new category of NCP for regulatory standards and engine

model years that have never been covered by NCPs before. It also fundamentally changes the

competitive landscape in the heavy heavy-duty diesel engine market for model years 2012 and

2013. Before the Interim Final Rule, Navistar’s competitors could rest assured that Navistar would

either finally certify a 0.2 g/bhp-hr compliant engine or drop out of the market when it finally ran out

of credits for a given service class. But after the Interim Final Rule, the marketplace has been

turned upside-down. Navistar, far from certifying a compliant engine or finally acknowledging that its

gamble on non-SCR technology did not pay off and leaving the market, has been given a license to

sell noncompliant engines at a fraction of the cost of achieving actual compliance.
- 11 - February 2, 2012

Indeed, it is hard to see how any NCP penalty rulemaking could be a “limited” change.

NCPs are binary—either they exist for a certain emission standard in a certain model year or they do

not. And when they do exist, they enable the sale of engines that would otherwise be illegal. That is

why notice and comment is so essential when NCPs are permitted. Only if the industry is allowed to

participate before the rule issues can EPA meet its statutory mandate to “remove any competitive

disadvantage to manufacturers whose engines or vehicles achieve the required degree of emission

reduction.” CAA § 206(g)(3)(E), 42 U.S.C. § 7525(g)(3)(E).

But even if EPA’s statement that the Interim Final Rule is a limited adjustment were true,

which it is not, it would not be legally sufficient “good cause” under the APA. As the D.C. Circuit has

explained, “our cases instruct that ‘the limited nature of the rule cannot in itself justify a failure to

follow notice and comment procedures.’” Tenn. Gas Pipeline Co. v. FERC, 969 F.2d 1141, 1145

(D.C. Cir. 1992) (quoting Council of S. Mountains, Inc., 653 F.2d at 582). If the limited scope of a

rule were enough to excuse notice and comment, “agencies could issue interim rules of limited effect

for any plausible reason, irrespective of the degree of urgency. Should this be allowed, the good

cause exception would soon swallow the notice and comment rule.” Id. Given that there is little—

indeed, no—urgency to implement NCPs, the purported limited scope of the Interim Final Rule is no

grounds to validate its issuance without proper notice and comment.

Nor can EPA brush aside its notice-and-comment obligations by pointing to previous

comments that the Agency has solicited. First, those comments are stale: EPA last solicited

comments on NCPs in 2002. By any measure of relevance, the industry and public’s views on what

NCPs should have looked like in 2002 have no bearing on whether NCPs should be permitted in

2012 and, if so, at what price.10 To the extent an agency can ever sidestep notice and comment by

pointing to comments made in the past, it must rely on comments of far more recent vintage. Musty

comments from a decade ago will not do.

More importantly, EPA also ignores the fact that the subject matter of the current rules—

NCPs for model year 2010 NOx standards—have never been subjected to public notice and

comment. EPA identifies specific provisions that it is not revisiting with the issuance of the Interim

Final Rule—“how to calculate penalties from the penalty parameters, how to determine a compliance

level, or how to report to EPA.” 77 Fed. Reg. at 4,680. What it fails to mention are the changes it is

making to the provisions governing the upper limit determination and of course, the fact that for the

first time it is making NCPs available and setting the associated cost parameters for the 2010 NOx

emission standard.

c. EPA’s third justification—that the Interim NCP Rule is “limited in duration”—is also

factually wrong and legally insufficient. The statement is factually wrong because two model years is

not a limited time in the trucking business or engine-manufacturing industry. Two model years of

NOx noncompliant engines will have effects that stretch for much longer than two years. A heavy

10 As the D.C. Circuit has held, “‘[a]lthough the Administrative Procedure Act does not establish a ‘useful

life’ for a notice and comment record, clearly the life of such a record is not infinite.’” Mobil Oil Corp. v.

EPA, 35 F.3d 579, 584 (D.C. Cir. 1994) (quoting Action on Smoking & Health v. Civil Aeronautics Bd.,

713 F.2d 795, 800 (D.C. Cir. 1983)). Thus, in Action on Smoking and Health, the D.C. Circuit refused to

find that the record was sufficiently fresh when the latest comments solicited were between two and four

years old. 713 F.2d at 801. The Court’s reason was obvious: “It cannot be presumed that no evidence

relevant to the problem . . . could have developed in the interim.” Id. If comments between two and four

years old are insufficiently fresh to justify waiving notice and comment, comments that are close to ten

years old are positively rotten. Much has changed in the heavy-duty diesel engine market since then, and

the industry should have had the opportunity to bring those changes to EPA’s attention before it issued

the Interim Final Rule, not after.
- 12 - February 2, 2012

heavy-duty truck engine can be rebuilt an average of four times, giving it an effective useful life of

well over one million miles.11 In short, EPA’s decision to allow NCPs for Navistar’s engines now will

have an effect far beyond the two model years for which these NCPs are authorized. EPA’s

decision will stretch as long as Navistar’s noncompliant engines are on the road.

Moreover, the D.C. Circuit has never allowed notice-and-comment rulemaking to be excused

simply because a rule is only temporary. As the Court has recognized, its “tolerance of ‘temporary’

measures installed without a public airing may give [an] agency an apparent incentive to proceed

with its permanent rulemaking at a leisurely pace.” Mid-Tex Elec. Co-Op, Inc. v. FERC, 822 F.2d

1123, 1132 (D.C. Cir. 1987). The Interim Final Rule’s “interim” status is not enough to evade the

notice and comment requirement.

d. EPA’s final justification for ignoring its notice and comment obligations is its weakest. It

argues in the Interim Final Rule that “should EPA be incorrect in its projection that NCPs will be

needed during model year 2012, the fact that they will be available on an interim basis will have no

practical significance because manufacturers will not use them.” 77 Fed. Reg. at 4,680. According

to EPA, this shows there is “no risk to the public interest.” Id.

But this justification misses the point. The harm to the public interest from the Interim Final

Rule is not that NCPs will be made available on an interim basis and not be used. It is that Navistar

will use them and that will hurt both the environment and the competitive marketplace. Where, as

here, an agency’s justification is a “complete non sequitur,” it is arbitrary and capricious and its order

must be vacated. See Tenn. Gas Pipeline Co. v. FERC, 824 F.2d 78, 84 (D.C. Cir. 1987).

B. Absent a Stay, DTNA and DDC Will Suffer Irreparable Harm

A stay is also warranted because DTNA and DDC will be irreparably harmed by the Interim

Final Rule. First, if a stay is not granted, DTNA and DDC will suffer financial harm that they will

never be able to recoup. This is not a close question. Because the NCP is set so low, Navistar will

exploit a massive competitive advantage by producing nonconforming engines at a fraction of the

per-engine cost compliant manufacturers have to pay to achieve actual compliance. The disparity is

staggering: Navistar is permitted to produce an up to 0.5 g/bhp-hr noncompliant engine at the low

rate of $1,919 per engine. By contrast, the hardware and manufacturing costs alone are many times

that amount for complying manufacturers to meet the 0.2 g/bhp-hr standard.

EPA has created a no-win situation: Navistar has the dual benefits of not having to comply

with the 2010 NOx standard and not having to pay penalties equal to what it actually costs other

manufacturers to comply. In fact, the NCP is so grossly inadequate that compliant manufacturers

will be forced to consider using the NCPs in order to remove the significant competitive advantage

that EPA has impermissibly provided to Navistar.

And unlike a garden-variety civil suit—where those tens of millions of dollars could be

recouped later—EPA enjoys sovereign immunity. And that is why the significant losses that DTNA

and DDC will suffer are irreparable. As the Eighth Circuit has held, the “threat of unrecoverable

economic loss . . . does qualify as irreparable harm.” Iowa Utils. Bd. v. FCC, 109 F.3d 418, 426 (8th

Cir. 1996) (emphasis added). There is nothing remarkable about that rule. The Tenth Circuit has

likewise emphasized that “[i]mposition of monetary damages that cannot later be recovered for

reasons such as sovereign immunity constitutes irreparable injury.” Chamber of Commerce v.

Edmondson, 594 F.3d 742, 770-71 (10th Cir. 2010); see also Cal. Pharmacists Ass’n v. Maxwell11 See EPA, Industry Characterization: On-Road Heavy Duty Diesel Engine Rebuilders 1, 3 (Jan. 3,

1997).
- 13 - February 2, 2012

Jolley, 563 F.3d 847, 852 (9th Cir. 2009) (“Because the economic injury doctrine rests . . . on

ordinary equity principles precluding injunctive relief where a remedy at law is adequate, it does not

apply where, as here, the . . . Plaintiffs can obtain no remedy in damages against the state because

of the Eleventh Amendment.”). In sum, DTNA and DDC will suffer irreparable harm from the Interim

Final Rule because they will suffer significant monetary losses for which they will have no recourse

against EPA to recover.

Moreover, the Interim Final Rule will cause irreparable damage to the environment. As EPA

itself recognizes, NOx is a major component of smog, which can result in a myriad of illnesses,

including “bronchitis, aggravated coughing, and chest pain” as well as “increased incidence/severity

of respiratory problems.”12 Allowing Navistar to pay artificially low NCPs, while producing and selling

engines that pollute at more than twice the legal limit creates excess NOx emissions on the order of

1.01 tons per engine over its effective useful life of one million miles, or 67,024 tons over Navistar’s

projected 2012 fleet of 66,360 engines. The air quality impacts will not be felt only in 2012 and

2013, but over the entire time period that vehicles with these engines are on the road—which could

equate to more than one million miles traveled with the engine rebuilds common to the industry.

C. Neither EPA nor Navistar Will Be Injured by a Stay Pending Review

A stay is further called for because neither EPA nor Navistar will be injured by a stay of the

Interim Final Rule pending appeal. EPA will certainly not be injured by a stay pending review in the

D.C. Circuit. Indeed, EPA will benefit because, if a stay is granted, noncomplying engines will be

kept off the road while review takes place in the D.C. Circuit. That, in turn, will benefit the quality of

the air that the Clean Air Act and EPA exist to protect. Moreover, EPA will save valuable

administrative resources. If the Interim Final Rule is not stayed, but is later overturned by the D.C.

Circuit—as it likely will be—EPA will have wasted its time and effort implementing the Interim Final

Rule and certifying Navistar’s noncompliant engines, only to have that work undone. EPA has

already issued the Notice of Proposed Rulemaking seeking comments on the proposed NCPs that

are designed to supersede those made effective by the Interim Final Rule. Postponing the

effectiveness of the Interim Final Rule NCPs until that rulemaking process is completed will allow

EPA to adhere to its statutory and regulatory mandates, accept and consider public comments

received, and issue more appropriate and justifiable NCPs. Staying the Interim Final Rule can only

benefit, not harm, EPA.

Moreover, a stay pending review would not harm Navistar. EPA has only speculated that

Navistar may run out of credits some time in 2012. Specifically, EPA indicated that Navistar has

NOx emission credits remaining, but EPA suspects that Navistar “could exhaust its supply of heavy

heavy-duty engine NOx credits as early as this year.” 77 Fed. Reg. at 4,680 (emphasis added).

However, subsequent to the EPA Administrator’s signing of the Interim Final Rule, Navistar came

out with an official company announcement that it would submit an application for certification of a

0.2 g/bhp-hr compliant engine as early as February.13 And conveniently, on the same day that the

Interim Final Rule was published in the Federal Register and the NCPs took effect, Navistar

12 EPA, Human Health and Environmental Effects of Emissions from Power Generation 1,

http://www.epa.gov/captrade/documents/power.pdf; see also EPA, Nitrogen Oxides – Health,

http://www.epa.gov/air/nitrogenoxides/ (describing the adverse health effects from NOx emissions,

particularly higher NOx concentrations found near vehicles and roadways).

13 See Navistar Letter to Dealers (Jan. 26, 2012) (“Navistar will submit a 0.2g NOx in-cylinder Big Bore

engine for production certification in the coming weeks.”); Navistar Press Release, Navistar to Host

Annual Analyst and Investor Day February 1, http://www.navistar.com/Navistar/News/Newsroom# (Jan.

20, 2012) (“As previously announced, the company will soon be submitting a .2 NOx (g/hp-hr) engine for

certification.”).
- 14 - February 2, 2012

submitted certification data for a 0.2 g/bhp-hr engine to EPA.14 This highlights the folly of issuing an

NCP when no manufacturer has even made a formal written request for such extraordinary

measures. With the certification of a 0.2 g/bhp-hr engine, Navistar will no longer need the NCPs

EPA has rushed to issue, and Navistar itself has thus now confirmed that there would be no

irreparable harm. At most, Navistar may have a gap of a few weeks in which it may not be able to

sell certain of its engines. Although Navistar may be unable to certify a full line of heavy heavy-duty

diesel engines for every day of model year 2012 without the Interim Final Rule, that would not be a

legally cognizable harm. A stay pending appeal “rests . . . on ordinary equity principles,” Cal.

Pharmacists Ass’n, 563 F.3d at 852, and as the ancient maxim regarding equity goes: “equity aids

the vigilant and not those who slumber on their rights.” Pro Football, Inc. v. Harjo, 565 F.3d 880, 884

(D.C. Cir. 2009). Navistar cannot claim harm from a stay of the Interim Final Rule because it

slumbered on its rights when it failed to seek NCPs for the 2010 NOx standard through notice-andcomment back in 2009, when it claimed in lawsuits against EPA that the standard was infeasible.

Nor can Navistar claim harm because it failed to seek NCPs for the 2012 and 2013 model years

when it first knew or should have known of its impending credit exhaustion, certainly earlier than late

2011. EPA will not be harmed by a stay of the Interim Final Rule, and any harm to Navistar could,

and should, have been mitigated by Navistar itself as long ago as 2009. The balance of the equities

favors a stay.

D. A Stay Is in the Public Interest

Finally, the public interest favors an injunction. For one, “[t]he public interest is served when

administrative agencies comply with their obligations under the APA.” N. Mariana Islands v. United

States, 686 F. Supp. 2d 7, 21 (D.D.C. 2009); see also Creosote Council v. Johnson, 555 F. Supp. 2d

36, 40 (D.D.C. 2008) (stating that there is a “general public interest in open and accountable agency

decision-making”).

But more importantly, the Clean Air Act allows NCPs as a last resort, not a first. Although

the Act grudgingly permits NCPs when there is no other way for a standard to be met, the Act

prefers the solution that SCR-equipped engine manufacturers like DDC and DTNA reached:

complying with the standard. It is undoubtedly in the public interest for Navistar’s noncompliant

engines to be kept off the road while the D.C. Circuit determines whether to uphold EPA’s

unprecedented exercise of NCP rulemaking.
