[EPA-R08-OAR-2010-0909; FRL-9228-9]


Finding of Substantial Inadequacy of Implementation Plan; Call 
for Utah State Implementation Plan Revision

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: Pursuant to sections 110(a)(2)(H) and 110(k)(5) of the Clean 
Air Act, EPA is proposing to find that the Utah State Implementation 
Plan (SIP) is substantially inadequate to attain or maintain the 
national ambient air quality standards or to otherwise comply with the 
requirements of the Clean Air Act. Specifically, the SIP includes Utah 
rule R307-107, which exempts emissions during unavoidable breakdowns 
from compliance with emission limitations. This rule undermines EPA's, 
Utah's, and citizens' ability to enforce emission limitations that have 
been relied on to ensure attainment or maintenance of the national 
ambient air quality standards or meet other Clean Air Act requirements. 
If EPA finalizes this proposed finding of substantial inadequacy, Utah 
will be required to revise its SIP to correct this deficiency within 12 
months of the effective date of our final rule. If EPA finds that Utah 
has failed to submit a complete SIP revision as required by a final 
rule or if EPA disapproves such a revision, such finding or disapproval 
would trigger clocks for mandatory sanctions and an obligation for EPA 
to impose a Federal Implementation Plan. EPA is also proposing that if 
EPA makes such a finding or disapproval, sanctions would apply 
consistent with 40 CFR 52.31, such that the offset sanction would apply 
18 months after such finding or disapproval and highway funding 
restrictions would apply six months later unless EPA first takes action 
to stay the imposition of the sanctions or to stop the sanctions clock 
based on the State curing the SIP deficiencies. EPA is also requesting 
comment on whether EPA should exercise its discretionary authority 
under the Clean Air Act to impose highway funding restrictions in all 
areas of the State, not just in nonattainment areas.

II. Background

    On September 20, 1999, Assistant Administrator for Enforcement and 
Compliance Assurance, Steven A. Herman, and Assistant Administrator for 
Air and Radiation, Robert Perciasepe, issued the EPA's most recent 
policy on appropriate State Implementation Plan (SIP) provisions 
addressing excess emissions during periods of startup, shutdown and 
malfunction (SSM). ``State Implementation Plans: Policy Regarding 
Excess Emissions During Malfunctions, Startup and Shutdown'' (1999 
Policy). The 1999 Policy indicated that it was expanding on and 
clarifying two previous policies issued in 1982 and 1983 by then 
Assistant Administrator for Air, Noise and Radiation Kathleen Bennett 
(``1982 Policy'' and ``1983 Policy'').
    In the 1982 and 1983 Policies, Assistant Administrator Bennett 
enunciated the Agency's position that SIPs should not be approved if 
they include exemptions for excess emissions during malfunction 
events.\1\ These policies reflect the Agency's interpretation that 
broad exemptions from compliance with emission limitations during 
periods of malfunction prevent a SIP from adequately ensuring 
attainment and maintenance of national ambient air quality standards 
(NAAQS). For purposes of demonstrating attainment and maintenance, 
states rely on assumed compliance with emission limitations. See, e.g., 
Clean Air Act (CAA) sections 110(a)(2)(A) and (C); 40 CFR 51.112; Train 
v. NRDC, 421 U.S.

[[Page 70890]]

60, 78-79 (1975). Thus, the 1982 and 1983 Policies indicated that, 
because SIPs must provide for attainment and maintenance of the NAAQS, 
any SIP provisions addressing malfunctions must be narrowly drawn and 
should not provide a blanket exemption from compliance with emission 
limitations; all periods during which emissions exceed emission 
limitations (``excess emissions'') should constitute violations under 
the SIP.
---------------------------------------------------------------------------

    \1\ As indicated above, the 1982, 1983, and 1999 Policies also 
address excess emissions provisions for startup and shutdown events. 
However, because our proposed action only addresses a malfunction 
provision--Utah's unavoidable breakdown rule--we are not including 
any further discussion of the Policies as they relate to startup and 
shutdown.
---------------------------------------------------------------------------

    The 1982 and 1983 Policies stated that EPA could approve SIP 
revisions that incorporated an enforcement discretion approach as 
described in the Policies. This enforcement discretion approach 
envisioned commencement of a proceeding to notify the source of its 
violation and a demonstration by the source that the excess emissions, 
``though constituting a violation,'' were due to an unavoidable 
malfunction. Following the proceeding and consideration of specific 
criteria, the state agency would decide whether to pursue an 
enforcement action. The 1982 and 1983 Policies also advised that the 
state could choose not to include in the SIP any provision on 
malfunctions, which reflected the fact that the CAA does not require 
states to include in SIPs any form of relief for violations caused by 
malfunctions.
    EPA understood that some malfunctions are unavoidable: ``Generally, 
EPA agrees that the imposition of a penalty for sudden and unavoidable 
malfunctions caused by circumstances entirely beyond the control of the 
owner and/or operator is not appropriate.'' (1982 and 1983 Policies). 
However, EPA was also mindful of its duty under the CAA to protect the 
NAAQS:

    ``The rationale for establishing these emissions as violations, 
as opposed to granting automatic exemptions, is that SIPs are 
ambient-based standards and any emissions above the allowable may 
cause or contribute to violations of the national ambient air 
quality standards. Without clear definitions and limitations, these 
automatic exemption provisions could effectively shield excess 
emissions arising from poor operation and maintenance or design, 
thus precluding attainment. Additionally, by establishing an 
enforcement discretion approach and by requiring the source to 
demonstrate the existence of an unavoidable malfunction on the 
source, good maintenance procedures are indirectly encouraged.'' 
(1982 Policy.) \2\
---------------------------------------------------------------------------

    \2\ Even prior to the issuance of the 1982 and 1983 Policies, it 
was our interpretation that all excess emissions, regardless of 
cause, should be treated as violations so as to provide sources with 
the incentive to properly design their facilities in the first 
instance and to improve their operation and maintenance practices 
over time. See, e.g., 42 FR 58171 (November 8, 1977).

    The 1999 Policy reiterated EPA's interpretation that all periods of 
excess emissions should be considered violations. However, the 1999 
Policy reflected our interpretation that a state could include a 
narrowly crafted affirmative defense provision in the SIP as an 
alternative to an enforcement discretion provision. Under this 
approach, a SIP could provide an affirmative defense to an enforcement 
action for penalties, but not to an action for injunctive relief. The 
Agency explained that because periods of excess emissions could 
undermine attainment and maintenance of the NAAQS and protection of 
prevention of significant deterioration (PSD) increments, an 
affirmative defense to an action for injunctive relief would not be 
appropriate.\3\
---------------------------------------------------------------------------

    \3\ In a 2009 decision, the United States Court of Appeals for 
the Tenth Circuit held that the policy was a ``reasonable 
interpretation of the Clean Air Act.'' Arizona Public Service 
Company v. EPA, 562 F.3d 1116, 1129 (10th Cir. 2009). See also 
Michigan Dept. of Environmental Quality v. EPA, 230 F.3d 181 (6th 
Cir. 2000).
---------------------------------------------------------------------------

    We also indicated in the 1999 Policy that we would not approve a 
rule that would bar EPA or citizen enforcement based on a state's 
decision to exercise its discretion not to pursue an enforcement 
action. EPA explained that such a rule would be inconsistent with the 
regulatory scheme established in Title I of the CAA.
    Finally, the 1999 Policy noted that some SIPs had been approved 
that appeared to be in conflict with EPA's SSM policies. The Policy 
indicated that EPA Regional Offices should work with the states to 
ensure SIPs were consistent with EPA's interpretation of the Act's 
requirements.
    Since the 1999 Policy was issued, EPA Region VIII has worked with 
states within the Region to ensure that their SIPs are consistent with 
EPA's interpretation of the Act as set forth in the 1982, 1983, and 
1999 Policies.\4\ Shortly after the 1999 Policy was issued, we advised 
Utah that its unavoidable breakdown rule was inconsistent with the CAA, 
and since that time, we have asked Utah several times to revise the 
rule. Among other things, the rule provides that ``emissions resulting 
from an unavoidable breakdown will not be deemed a violation * * * ''
---------------------------------------------------------------------------

    \4\ For example, at our request, the State of Colorado revised 
its SIP provisions for SSM. We approved revised provisions in 2006 
(71 FR 8958, February 22, 2006) and 2008 (73 FR 45879, August 7, 
2008). At our request, the State of Wyoming revised its SIP 
provision for malfunctions. We approved the revised provision on 
April 16, 2010 (75 FR 19886). At our request, the State of North 
Dakota revised its SIP provision for malfunctions and submitted the 
revised provision to us on April 6, 2009. That provision is modeled 
on the Wyoming provision, and we intend to propose action on it 
shortly.
---------------------------------------------------------------------------

    Some version of the Utah unavoidable breakdown rule has been in the 
SIP for many years. In 1980, EPA approved a variation of the current 
Utah unavoidable breakdown rule. In the proposed rulemaking preamble, 
EPA stated that it could ``not fully approve Regulation 4.7 because it 
exempts certain excess emissions from being violations of the Air 
Conservation Regulations,'' but then proposed to approve Utah's 
malfunction procedures because any exemptions granted by the Utah 
Executive Secretary ``are not applicable as a matter of federal law.'' 
44 FR 28688, 28691 (May 16, 1979). EPA's final approval of the 
regulation mirrored this concept. 45 FR 10761, 10763 (February 19, 
1980). However, thirty years later, it is not clear how EPA reached the 
conclusion that exemptions granted by Utah would not apply as a matter 
of federal law or whether a court would honor EPA's interpretation; the 
Utah rule itself makes no reference to a reservation of federal 
authority. Instead, the rule merely states that information submitted 
by a source regarding a breakdown event would be ``used by the 
executive secretary in determining whether a violation has occurred 
and/or the need of further enforcement action.''
    EPA approved a revised version of the rule in 1994 with no preamble 
discussion, except to say that the Utah air rules had been renumbered 
and new requirements had been added (59 FR 35036, July 8, 1994; 40 CFR 
52.2320(c)(25)(i)(A)). The key aspects of the unavoidable breakdown 
rule remained the same.
    Subsequently, Utah again re-numbered its entire SIP regulations, 
and EPA approved the re-numbered regulations, including the re-numbered 
unavoidable breakdown rule, to conform the federally-approved SIP to 
the numbering of Utah's regulations. (70 FR 59681 (October 13, 2005).) 
EPA did not consider the substance of the unavoidable breakdown rule in 
that action. Instead, EPA indicated that it was only approving the 
renumbering and that attempts to address problems in the rules were 
ongoing:

    ``By this action, EPA has reviewed the Utah Department of Air 
Quality's (UDAQ) SIP submittals and found that these SIP submittals 
only renumber and restructure UDAQ's rules. EPA has not reviewed the 
substance of these rules as part of this action; EPA approved these 
state rules into the SIP in previous rulemakings. The EPA is now 
merely approving the renumbering system submitted by the State. The 
current version of UDAQ's rules does not contain substantive changes 
from the prior codification that we

[[Page 70891]]

approved into the SIP. EPA acknowledges that there are ongoing 
discussions with Utah to address EPA's concerns with some rule 
language that EPA previously approved into the Utah SIP. In an April 
18, 2002 letter from Richard Sprott, Director of Utah's Division of 
Air Quality, to Richard Long, Director of the Air and Radiation 
Program in EPA Region 8, UDAQ committed to work with us to address 
our concerns with the Utah SIP. Because the SIP submittals only 
restructure and renumber the existing SIP-approved regulations, 
contain no substantive changes, and UDAQ has committed to address 
EPA's concerns, we believe it is appropriate to propose to approve 
the submittal. Approving the restructured and renumbered Utah rules 
into the SIP will also facilitate future discussions on the rules. 
EPA will continue to require the State to correct any rule 
deficiencies despite EPA's approval of this recodification.'' (70 FR 
at 59683)

    Over the years Utah personnel acknowledged that the unavoidable 
breakdown rule should be revised and committed to do so. For example, 
in a January 17, 2001 letter to EPA, Rick Sprott, then the Executive 
Director of the Utah Division of Air Quality (UDAQ), wrote the 
following:

    ``With respect to EPA's concern with the breakdown rule 
currently approved into Utah's SIP, UDAQ agrees that the rule would 
benefit from clarification.''

Later, in an April 18, 2002 letter,\5\ Mr. Sprott wrote the 
following:

    \5\ April 18, 2002 letter from Rick Sprott, UDAQ to Richard 
Long, EPA referred to as 15-point commitment letter.
---------------------------------------------------------------------------

    ``The Utah Division of Air Quality commits to work with EPA in 
good faith to develop approvable SIP revisions, which address the 
following issues:
    * * *
    8. Unavoidable breakdown rules and consistency with the EPA 
September 20, 1999 policy regarding such breakdowns.''

    In 2004, UDAQ staff drafted replacement rule language for the 
breakdown rule, consulted with EPA and other stakeholders, and 
initiated the State's public process for SIP revisions. EPA provided 
detailed comments regarding draft rule language and in January 2005 
traveled to Utah to provide a detailed presentation to UDAQ and 
industry stakeholders regarding EPA's interpretations of the CAA and 
concerns regarding UDAQ's proposed replacement rule language.
    Following the January 2005 meeting, Fred Nelson of the Utah 
Attorney General's Office prepared another draft of possible 
replacement rule language, which he shared with EPA and industry 
representatives. In May 2005, in an attempt to ensure that any rule 
revision could ultimately be approved by EPA, EPA provided specific 
comments and suggestions to Mr. Nelson regarding this draft. However, 
UDAQ did not pursue further rulemaking action at that time.
    During the August 2, 2006 midyear review between UDAQ and EPA, the 
unavoidable breakdown rule was again discussed. Mr. Sprott indicated 
that he did not want to pursue further action on the unavoidable 
breakdown rule given the disagreement between Utah industry and EPA. 
However, he said he was aware that Colorado was in the process of 
revising its malfunction rule, that he would be happy to benefit from 
the Colorado process, and that if it concluded successfully, he would 
lead the effort to adopt a new rule in Utah. Mr. Sprott also said that 
while he wanted to complete a rule revision through a cooperative 
process, if it couldn't be done that way, EPA should do a SIP call. 
Although Colorado subsequently adopted a revised malfunction rule and 
we approved it into the SIP without challenge (73 FR 45879, August 7, 
2008), we are unaware of any further steps taken by Utah to revise its 
unavoidable breakdown rule.
    To assure that a state's SIP provides for attainment and 
maintenance of the NAAQS, and compliance with other CAA requirements, 
sections 110(a)(2)(H) and 110(k)(5) of the CAA authorize EPA to find 
that a SIP is substantially inadequate to attain or maintain a NAAQS, 
or comply with other CAA requirements, and to require (``call for'') 
the state to submit, within a specified time period, a SIP revision to 
correct the inadequacy. This CAA requirement for a SIP revision is 
known as a ``SIP call.'' The CAA authorizes EPA to allow a state up to 
18 months to respond to a SIP call.
    On September 3, 2009, WildEarth Guardians (WEG) filed a complaint 
against EPA in the U.S. District Court for the District of Colorado 
(Civil Action No. 09-cv-02109-MSK-KLM) seeking, among other things, an 
injunction requiring EPA to issue a SIP call to Utah to revise the 
unavoidable breakdown rule. On November 23, 2009, we entered into a 
Consent Decree with WEG that requires us to sign a notice of final 
rulemaking action by February 28, 2011. In that final rulemaking action 
we must determine whether the Utah breakdown provision (Utah 
Regulations 307-107-1 through 307-107-5) renders the Utah SIP 
``substantially inadequate'' within the meaning of section 110(k)(5) of 
the CAA, 42 U.S.C. 7410(k)(5), and, if EPA determines that the SIP is 
substantially inadequate, require the State to revise the SIP as it 
relates to the Utah breakdown provision. We intend to meet the 
requirements of the Consent Decree through the rulemaking action we are 
initiating today.

III. Why is EPA proposing a SIP call?

    Utah rule R307-107 contains various provisions that are 
inconsistent with EPA's interpretations regarding the appropriate 
treatment of malfunction events in SIPs and which render the Utah SIP 
substantially inadequate. As a result, we are calling for a SIP 
revision.

A. Deficiencies in R307-107-1

    R307-107-1 indicates it applies to all regulated pollutants 
including those for which there are NAAQS and states that ``emissions 
resulting from unavoidable breakdown will not be deemed a violation of 
these regulations.'' As described above, our interpretation of the CAA 
as expressed in our various policy statements since the early 1980s is 
that SIP provisions may not provide that periods of excess emissions 
are not violations.
    We believe the Utah rule's broad exemption undermines the ability 
to protect the NAAQS, PSD increments, and visibility through 
enforcement of emission limits contained in the SIP. The Utah SIP 
contains generic emission limits that help areas maintain the NAAQS as 
well as emission limits specifically modeled and relied on to bring 
areas not attaining the NAAQS into attainment. See, e.g., Utah rule 
R307-201 (``General Emission Standards'') and Section IX.H.1 of the 
Utah SIP (contains emission limits for the Utah County PM10 
nonattainment area SIP). Because the NAAQS are not directly enforceable 
against individual sources,\6\ SIPs rely on the adoption and 
enforcement of these generic and specific emission limits to attain and 
maintain the NAAQS, as well as to protect PSD increments and meet other 
CAA requirements, such as protection of visibility in Class I areas.
---------------------------------------------------------------------------

    \6\ See, e.g., Coalition Against Columbus Ctr. v. New York, 967 
F.2d 764, 769 (2d Cir. 1992); League to Save Lake Tahoe, Inc. v. 
Trounday, 598 F.2d 1164, 1173 (9th Cir. 1979); 57 FR 32276, July 21, 
1992.
---------------------------------------------------------------------------

    In the case of an unavoidable breakdown, the rule's exemption 
eliminates any opportunity to obtain injunctive relief that may be 
needed to protect the NAAQS, increments, and visibility. Thus, the rule 
impedes the ability to protect public health and the environment. 
Furthermore, the rule's exemption reduces a source's incentive to 
design, operate, and maintain its facility to meet emission limits at 
all times.
    We expect some commenters may assert that we need to show a direct 
causal link between unavoidable breakdown excess emissions and specific 
threats to or violations of the

[[Page 70892]]

NAAQS to conclude that the SIP is substantially inadequate. We do not 
agree. It is our interpretation that the fundamental integrity of the 
CAA's SIP process and structure are undermined if emission limits 
relied on to meet CAA requirements related to protection of public 
health and the environment can be violated without potential recourse. 
We do not believe we are restricted to issuing SIP calls only after a 
violation of the NAAQS has occurred or only where a violation can be 
directly linked to specific excess emissions. It is sufficient that 
emissions limits to which the unavoidable breakdown exemption applies 
have been, are being, and will be relied on to attain and maintain the 
NAAQS and meet other CAA requirements.\7\
---------------------------------------------------------------------------

    \7\ The U.S. Court of Appeals for the Eleventh Circuit has 
recognized that a SIP call under CAA section 110(k)(5) is the 
appropriate mechanism for EPA to require a change to an existing SSM 
provision in a SIP: ``EPA policy guidance cannot trump the SSM Rule 
adopted by Georgia and approved formally by the EPA * * * If the EPA 
believes that its current interpretation of the Clean Air Act 
requires Georgia to modify its SSM Rule, the EPA should require the 
state to revise its SIP to conform to EPA policy'' (citing CAA 
section 110(k)(5)).
---------------------------------------------------------------------------

    Our interpretation of the CAA is supported by sections 110 and 302 
of the CAA. Section 110(a)(2)(A) requires each SIP to include 
enforceable emission limitations necessary or appropriate to meet the 
CAA's applicable requirements. As noted above, these applicable 
requirements include attainment and maintenance of the NAAQS, 
prevention of significant deterioration, and improvement and protection 
of visibility in national parks and wilderness areas. Section 302(k) 
defines emission limitation as a requirement established by a state or 
EPA that ``limits the quantity, rate, or concentration of emissions of 
air pollutants on a continuous basis.'' (Emphasis added.) Because of 
the exemption in R307-107-1, emission limits in the Utah SIP that have 
been relied on by the State to demonstrate attainment and maintenance 
of the NAAQS and meet other CAA requirements do not limit emissions on 
a continuous basis and are not fully enforceable.
    R307-107-1 is also substantially inadequate because it applies to 
all regulated pollutants, not just NAAQS pollutants, and because it 
indicates that excess emissions from an unavoidable breakdown are not 
deemed a violation of ``these regulations.'' ``These regulations'' 
includes the totality of Utah's air pollution control regulations, 
which include the regulations Utah has incorporated by reference to 
receive delegation of federal authority--for example, New Source 
Performance Standards (NSPS) and National Emission Standards for 
Hazardous Air Pollutants (NESHAPS). See Utah rules R307-210 and R307-
214. To the extent any exemptions with respect to malfunctions from 
these technology-based standards are warranted, the federal standards 
contained in EPA's regulations already specify the appropriate 
exemptions. See, e.g., 40 CFR 60.48Da(c). No additional exemptions are 
warranted or appropriate. See, e.g., 40 CFR 60.10(a); 40 CFR 
63.12(a)(1); and the 1999 Policy, Attachment, page 3. Thus, R307-107-1 
is substantially inadequate because it improperly provides an exemption 
not contained in and not sanctioned by the delegated federal standards.
    Our interpretation, as it applies to both technology-based 
standards and SIP limits, is further supported by a 2008 U.S. Court of 
Appeals decision that vacated EPA's general malfunction exemption from 
CAA section 112(d) maximum achievable control technology (MACT) 
standards. Sierra Club v. EPA, 551 F.3d 1019 (DC Cir. 2008), cert. 
denied. The court vacated the exemption because it was inconsistent 
with the CAA's requirement that emission standards--such as the 112(d) 
MACT standards--must apply continuously, as expressed in section 302(k) 
of the CAA. The court specifically held that a regulatory provision 
establishing a general duty to minimize hazardous air pollutant (HAP) 
emissions during malfunctions was not an emission standard under CAA 
section 112. Although the decision addressed the HAP program and not 
the SIP program, it carries significant weight for the SIP program as 
well because section 302(k) is equally relevant for the SIP program. 
R307-107-1's broad malfunction exemption from ``these regulations'' is 
inconsistent with section 302(k) as interpreted by the Court in Sierra 
Club.
    As referenced in R307-107-1, ``these regulations'' would also 
include Utah's PSD and nonattainment major new source review (NSR) 
requirements. This means a source could use the provisions of R307-107 
to claim an exemption from best available control technology (BACT) or 
lowest achievable emission rate (LAER) limits in a major source permit 
for excess emissions resulting from an unavoidable breakdown. We have 
consistently interpreted the Act to not allow for outright exemptions 
from BACT limits, and the same logic applies to LAER limits. See, e.g., 
1977 memorandum entitled ``Contingency Plan for FGD Systems During 
Downtime as a Function of PSD,'' from Edward E. Reich to G.T. Helms and 
January 28, 1993 memorandum entitled ``Automatic or Blanket Exemptions 
for Excess Emissions During Startup and Shutdowns under PSD,'' from 
John B. Rasnic to Linda M. Murphy. As noted, in order to ensure non-
degradation of air quality at all times under the PSD program and 
protection of the NAAQS at all times, it is necessary for a source to 
comply with its permit limits at all times. This is another reason 
R307-107's exemption renders the Utah SIP substantially inadequate.

B. Deficiencies in R307-107-2

    R307-107-2 requires the source to submit information regarding an 
unavoidable breakdown to the executive secretary of Utah's Air Quality 
Board (UAQB) and indicates that the information ``shall be used by the 
executive secretary in determining whether a violation has occurred 
and/or the need of further enforcement action.'' In other words, the 
executive secretary shall determine whether the excess emissions were 
caused by an unavoidable breakdown and, thus, whether the excess 
emissions constitute a violation or not. This rule provision appears to 
give the executive secretary exclusive authority to determine whether 
excess emissions constitute a violation.\8\ We believe this is 
inconsistent with the enforcement structure contemplated by the CAA. 
Specifically, the CAA provides authority to enforce violations of SIP 
and other CAA emission limits to EPA and citizens as well as to the 
states. Thus, the CAA provides EPA and citizens with authority to 
pursue a violation even if a state chooses not to. See sections 113 and 
304 of the CAA. It is our interpretation, expressed in our 1999 Policy, 
that SIP provisions that give exclusive authority to a state to 
determine whether an enforcement action can be pursued for an 
exceedance of an emission limit are inconsistent

[[Page 70893]]

with the CAA's regulatory scheme. EPA and citizens, and any court in 
which they seek to file an enforcement claim, must retain the authority 
to independently evaluate whether a source's exceedance of an emission 
limit warrants enforcement action. Because a court could interpret 
section R307-107-2 as undermining the ability of EPA and citizens to 
independently exercise enforcement discretion granted by the CAA, it is 
substantially inadequate to comply with CAA requirements related to 
enforcement. Because it undermines the envisioned enforcement 
structure, attainment and maintenance of the NAAQS and compliance with 
other CAA requirements related to PSD, visibility, NSPS, and NESHAPS is 
less certain. Potential EPA and citizen enforcement provides an 
important safeguard in the event a state lacks resources or appropriate 
intention to enforce CAA violations. Thus, R307-107-2 renders the SIP 
substantially inadequate to attain or maintain the NAAQS or otherwise 
comply with the CAA.
---------------------------------------------------------------------------

    \8\ As we noted earlier, in a 1980 approval of a predecessor to 
the current unavoidable breakdown rule, EPA indicated that EPA might 
not approve exemptions granted by the State and that the State's 
exemption would not apply as a matter of federal law. Thirty years 
later, we are not sanguine that a court would uphold our 
interpretation, or that five years from now, anyone will remember 
that interpretation. See, e.g., U.S. v. Ford Motor Co., 736 F.Supp. 
1539 (W.D. Mo. 1990) and U.S. v General Motors Corp., 702 F.Supp. 
133 (N.D. Texas 1988) (EPA could not pursue enforcement of SIP 
emission limits where states had approved alternative limits under 
procedures EPA had approved into the SIP.) While we do not agree 
with the holdings of these cases, we think the reasonable course is 
to eliminate any uncertainty about reserved enforcement authority by 
requiring the State to revise or remove the unavoidable breakdown 
rule from the SIP.
---------------------------------------------------------------------------

C. Conclusion

    For the reasons stated above, EPA is proposing to find, pursuant to 
sections 110(a)(2)(H) and 110(k)(5) of the CAA, that the Utah SIP is 
substantially inadequate to attain or maintain the NAAQS or to 
otherwise comply with the requirements of the CAA. Utah rule R307-107 
improperly undermines EPA's, Utah's, and citizens' ability to enforce 
emission limitations that have been relied on in the SIP to ensure 
attainment and maintenance of the NAAQS or meet other CAA requirements. 
Pursuant to sections 110(a)(2)(H) and 110(k)(5) of the CAA, we are 
proposing to call for Utah to remove R307-107 from the SIP or revise it 
to be consistent with CAA requirements.
    We are proposing that Utah must respond to our SIP call within 12 
months of the effective date of a final rule issuing a SIP call. We 
think this is a reasonable amount of time for several reasons. First, 
Utah has been aware of our concerns for years. Utah previously 
initiated the State rulemaking process to address the SIP deficiencies 
but dropped its efforts when it couldn't achieve consensus. Second, 
industry and WildEarth Guardians' predecessor had extensive involvement 
in the development of the Colorado malfunction rule, which, as noted 
above, we approved in 2008. The Colorado malfunction rule is readily 
available online, and use of the Colorado rule as a template would give 
the UAQB a substantial head start in addressing the SIP deficiencies. 
Other examples of provisions that have been approved or promulgated by 
EPA for areas within the Region are also available. See, e.g., https://
yosemite.epa.gov/R8/R8Sips.nsf/641057911f6bd13987256b5f0054f380/
722dcc2462e7856a87256ef3005f6d4f/$FILE/Ch%201%20Sect%205.pdf (Wyoming 
air rules, Chapter 1, Section 5, approved at 75 FR 19886, April 16, 
2010); 73 FR 21418, 21464, April 21, 2008. Third, another option to 
address the deficiencies is to simply remove R307-107 from the SIP. 
Under this option, no time would be needed to develop replacement SIP 
rule language.

IV. What happens if EPA issues a final SIP call and the State of Utah 
does not submit a complete SIP revision that responds to the SIP call 
or if EPA disapproves a SIP revision that responds to the SIP call?

    If Utah fails to submit a complete SIP revision that responds to a 
final SIP call, CAA section 179(a) provides for EPA to issue a finding 
of State failure. Such a finding starts mandatory 18-month and 24-month 
sanctions clocks and a 24-month clock for promulgation of a federal 
implementation plan (FIP) by EPA. The two sanctions that apply under 
CAA section 179(b) are the 2-to-1 emission offset requirement for all 
new and modified major sources subject to the nonattainment new source 
review program and restrictions on highway funding. However, section 
179 leaves it up to the Administrator to decide the order in which 
these sanctions apply. EPA issued an order of sanctions rule in 1994 
(59 FR 39832, August 4, 1994, codified at 40 CFR 52.31) but did not 
specify the order of sanctions where a state fails to submit or submits 
a deficient SIP in response to a SIP call. However, the order of 
sanctions specified in that rule (40 CFR 52.31) should apply here for 
the same reasons discussed in the preamble to that rule. Thus, if EPA 
issues a final SIP call and Utah fails to submit the required SIP 
revision, or submits a revision that EPA determines is incomplete or 
that EPA disapproves, EPA proposes that the 2-to-1 emission offset 
requirement will apply for all new sources subject to the nonattainment 
new source review program 18 months following such finding or 
disapproval unless the State corrects the deficiency before that date. 
EPA proposes that the highway funding restrictions sanction will also 
apply 24 months following such finding or disapproval unless the State 
corrects the deficiency before that date. EPA is also proposing that 
the provisions in 52.31 regarding staying the sanctions clock and 
deferring the imposition of sanctions would also apply.
    Mandatory sanctions under section 179 generally apply only in 
nonattainment areas. By its definition, the emission offset sanction 
applies only in areas required to have a part D NSR program, typically 
areas designated nonattainment.\9\ Section 179(b)(1) expressly limits 
the highway funding restriction to nonattainment areas. Additionally, 
EPA interprets the section 179 sanctions to apply only in the area or 
areas of the State that are subject to or required to have in place the 
deficient SIP and for the pollutant or pollutants the specific SIP 
element addresses. In this case, mandatory sanctions would apply in all 
areas designated nonattainment for a NAAQS within the State because 
Utah rule R307-107 applies statewide and applies for all NAAQS 
pollutants.
---------------------------------------------------------------------------

    \9\ An exception to this, not relevant here, is areas located in 
the Ozone Transport Region, which are required to have a part D NSR 
program regardless of the area's designation. See CAA section 
184(b)(2).
---------------------------------------------------------------------------

    EPA has additional authority to impose discretionary sanctions 
under CAA section 110(m). EPA's authority to impose sanctions under 
section 110(m) is triggered by the same findings that trigger the 
mandatory imposition of sanctions. However, under section 110(m), EPA 
may impose sanctions more quickly than provided under the mandatory 
sanction provision and may also impose them in a broader area. 
Specifically, under section 110(m), EPA may impose sanctions ``any 
time'' after it has made a finding of deficiency or disapproved a SIP. 
In addition, EPA may impose the sanctions with respect to ``any portion 
of the State the Administrator determines reasonable and appropriate.'' 
Finally, although imposition of the 2-to-1 offset sanction is still 
limited by its terms to areas with part D NSR programs, the highway 
funding restrictions can be applied in areas designated as attainment 
or unclassifiable as well as those designated nonattainment. See 59 FR 
1476 (January 11, 1994); 40 CFR 52.30(d)(2). EPA may determine whether 
or not to use this authority in response to a SIP failure, and, thus, 
they are termed discretionary sanctions.
    Because only limited portions of the State are designated 
nonattainment, the mandatory sanctions would not be applicable in all 
areas of the State that are covered by the rule we have proposed is 
deficient. EPA is requesting comment on whether to exercise its 
discretionary authority to impose the highway funding restrictions 
sanction in all areas of the State, regardless of

[[Page 70894]]

designation, if it finalizes this proposed SIP call and the State fails 
to submit a complete SIP revision or EPA disapproves such revision. If 
EPA were to impose discretionary sanctions, EPA proposes that the same 
24-month clock would apply to the highway funding sanction as would 
apply under the mandatory sanctions.
    In addition to sanctions, if EPA finalizes this SIP call and then 
finds that the State failed to submit a complete SIP revision that 
responds to the SIP call or disapproves such revision, the requirement 
under section 110(c) would be triggered that EPA promulgate a FIP no 
later than two years from the date of the finding or the disapproval if 
the deficiency has not been corrected.

V. Proposed Action

    EPA is proposing that the Utah SIP is substantially inadequate to 
attain or maintain the NAAQS or to otherwise comply with requirements 
of the CAA due to significant deficiencies created by Utah's 
unavoidable breakdown rule, R307-107. Pursuant to CAA sections 
110(a)(2)(H) and 110(k)(5), EPA is proposing to require that Utah 
revise the SIP to correct the inadequacies and submit the revised SIP 
to EPA within 12 months of the effective date of a final rule finding 
the SIP substantially inadequate. EPA is proposing that mandatory 
sanctions under CAA section 179 would apply as provided in 40 CFR 50.31 
should Utah not submit a complete SIP consistent with a final SIP call 
requirement or should EPA disapprove any such submission. EPA is also 
requesting comment on whether EPA should exercise its discretionary 
authority under section 110(m) to impose highway funding restrictions 
in all areas of the State if 24 months after a sanctions clock has been 
triggered, the State has still not corrected the deficiency that 
triggered the sanctions clock.
    We are soliciting comments on these proposed actions. Final 
rulemaking will occur after consideration of any comments.

VI. Statutory and Executive Order Reviews

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
proposed action is not a ``significant regulatory action'' and 
therefore is not subject to review by the Office of Management and 
Budget. For this reason, this action is also not subject to Executive 
Order 13211, ``Actions Concerning Regulations That Significantly Affect 
Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001).
    This proposed action would only require the State of Utah to revise 
UAC R307-107 to address requirements of the CAA. Accordingly, the 
Administrator certifies that this proposed action would not have a 
significant economic impact on a substantial number of small entities 
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.) because 
this proposed action would not impose any requirements on small 
entities.
    Since the only costs of this action would be those associated with 
preparation and submission of the SIP revision, EPA has determined that 
this proposed action would not include a Federal mandate that may 
result in expenditures of $100 million or more to either state, local, 
or tribal governments in the aggregate, or to the private sector in any 
one year. Accordingly, this proposed action is not subject to the 
requirements of sections 202 or 205 of the unfunded mandates reform act 
(UMRA).
    In addition, since the only regulatory requirements of this 
proposed action would apply solely to the State of Utah, this action is 
not subject to the requirements of section 203 of UMRA because it 
contains no regulatory requirements that might significantly or 
uniquely affect small governments.
    Since this proposed action would impose requirements only on the 
State of Utah, it also does not have tribal implications. It would not 
have a substantial direct effect on one or more Indian tribes, on the 
relationship between the Federal Government and Indian tribes, or on 
the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000).
    This proposed action also does not have Federalism implications 
because it would not have substantial direct effects on the states, on 
the relationship between the national government and the states, or on 
the distribution of power and responsibilities among the various levels 
of government, as specified in Executive Order 13132 (64 FR 43255, 
August 10, 1999), because it would simply maintain the relationship and 
the distribution of power and responsibilities between EPA and the 
states as established by the CAA. This proposed SIP call is required by 
the CAA because EPA believes the current SIP is substantially 
inadequate to attain or maintain the NAAQS or comply with other CAA 
requirements. Utah's direct compliance costs would not be substantial 
because the proposed SIP call would require Utah to submit only those 
revisions necessary to address the SIP deficiencies and applicable CAA 
requirements.
    EPA interprets Executive Order 13045 ``Protection of Children from 
Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 
1997) as applying only to those regulatory actions that concern health 
or safety risks, such that the analysis required under section 5-501 of 
the Executive Order has the potential to influence the regulation. This 
action is not subject to Executive Order 13045 because it would not 
establish an environmental standard, but instead would require Utah to 
revise a state rule to address requirements of the CAA.
    Section 12 of the National Technology Transfer and Advancement Act 
of 1995 requires Federal agencies to evaluate existing technical 
standards when developing a new regulation. To comply with the National 
Technology Transfer and Advancement Act, EPA must consider and use 
``voluntary consensus standards'' (VCS) if available and applicable 
when developing programs and policies unless doing so would be 
inconsistent with applicable law or otherwise impractical. In making a 
finding of a SIP deficiency, EPA's role is to review existing 
information against previously established standards. In this context, 
there is no opportunity to use VCS. Thus, the requirements of section 
12(d) of the National Technology Transfer and Advancement Act of 1995 
(15 U.S.C. 272 note) do not apply.
    This proposed action would not impose an information collection 
burden under the provisions of the Paperwork Reduction Act of 1995 (44 
U.S.C. 3501 et seq.), since it would only require the State of Utah to 
revise UAC R307-107 to address requirements of the CAA.
