Approval and Promulgation of Implementation Plans; Kentucky; 
Approval of Revisions to the Jefferson County Portion of the Kentucky 
SIP; Emissions During Startups, Shutdowns, and Malfunctions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve part of a revision to the Kentucky 
State Implementation Plan (SIP), submitted by the Commonwealth of 
Kentucky, through the Kentucky Division for Air Quality (KDAQ), on 
March 22, 2011. The proposed revision was submitted by KDAQ on behalf 
of the Louisville Metro Air Pollution Control District (District), 
which has jurisdiction over Jefferson County, Kentucky. The portion of 
the revision that EPA is proposing for approval modifies the Regulation 
entitled, ``Emissions During Startups, Shutdowns, Malfunctions and 
Emergencies'' in the Jefferson County portion of the Kentucky SIP. EPA 
is proposing approval of this portion of the March 22, 2011, SIP 
revision because the Agency has determined that it is in accordance 
with the requirements for SIP provisions under the Clean Air Act (CAA 
or Act). EPA will act on the other portions of KDAQ's March 22, 2011, 
submittal, which are severable and unrelated, in a separate action.

DATES: Comments must be received on or before June 20, 2013.

I. What action is EPA proposing?

    EPA is proposing to approve a revision to the Jefferson County 
portion of the Kentucky SIP to incorporate revisions to Jefferson 
County Regulation 1.07, ``Emissions During Startups, Shutdowns, 
Malfunctions and Emergencies'' (referred to hereafter as the 
``Jefferson County SSM rule'').\1\ The revision modifies all seven 
sections of the existing version of Regulation 1.07 currently in the 
EPA-approved SIP for Jefferson County. EPA believes that the changes to 
the Jefferson County SSM rule are consistent with CAA requirements that 
apply to excess emissions during startup, shutdown and malfunction 
(SSM) events. In addition, EPA believes that these changes will correct 
existing concerns about the prior version of the Jefferson County SSM 
rule in the SIP for this Area, as explained below. Please refer to the 
docket for this rulemaking for the complete text of the adopted 
provisions.
---------------------------------------------------------------------------

    \1\ In 2003, the City of Louisville and Jefferson County 
governments merged and the ``Jefferson County Air Pollution Control 
District'' was renamed the ``Louisville Metro Air Pollution Control 
District.'' However, each of the regulations in the Jefferson County 
portion of the Kentucky SIP still has the subheading ``Air Pollution 
Control District of Jefferson County.'' Thus, to be consistent with 
the terminology used in the SIP, we refer throughout this notice to 
regulations contained in Jefferson County portion of the Kentucky 
SIP as the ``Jefferson County'' regulations.
---------------------------------------------------------------------------

II. What is the background of the Jefferson County Rule on startups, 
shutdowns, malfunctions (SSM) and emergencies?

    The regulation of emissions from stationary sources is a part of 
the Louisville Metro Air Pollution Control District's program for 
attaining and maintaining compliance with the national ambient air 
quality standards (NAAQS) and for meeting other CAA requirements. The 
current EPA-approved SIP for the Jefferson County area incorporates a 
prior version of the Jefferson County SSM rule that includes certain 
provisions applicable to excess emissions from such sources during 
startup, shutdown, malfunction, and emergency events. EPA published 
approval of the original version of this rule on January 25, 1980. See 
45 FR 6092. On February 11, 1999, Kentucky submitted multiple changes 
to the Jefferson County portion of the Kentucky SIP, which EPA approved 
on October 23, 2001. See 66 FR 53658. Among other elements, Kentucky's 
February 11, 1999, submittal included several changes to the Jefferson 
County SSM rule. The submittal added to this rule a definition of 
``Emergency'' in Section 1, Definitions, and a new Section 5, 
Emergencies, which contains an affirmative defense provision for 
emergencies that is very similar to the affirmative defense provision 
of the title V operating permit regulations. See 40 CFR 70.7(g). 
Additionally, the February 11, 1999, submittal modified Section 2, 
Excess Emissions, of the rule such that excess emissions would not be 
deemed in violation of otherwise applicable emission limits in the SIP 
if, based upon a showing by the owner or operator of the source and an 
affirmative determination by the District, certain requirements 
regarding startups and shutdowns, malfunctions, and emergencies are 
satisfied. Those requirements, as revised by the February 11, 1999, 
submittal, are specified in the following sections of the Jefferson 
County SSM rule: Section 3, Startup or Shutdown; Section 4, 
Malfunctions; Section 5, Emergencies; Section 6, Initial Notification 
and Reporting Requirements for Malfunctions and Emergencies; and 
Section 7, Extended Malfunctions and Emergencies.
    Acknowledging deficiencies in the Jefferson County SSM rule, the 
District proactively adopted changes on June 21, 2005. The District 
adopted these changes with the intent of correcting inconsistencies 
between its rule and the CAA and EPA guidance,\2\ regarding SIP 
provisions that apply to the treatment of excess emissions that may 
occur during source startup, shutdown, maintenance, and malfunction 
events. These changes were included in the March 22, 2011, SIP revision 
provided to EPA by KDAQ. The most salient features of these latest 
changes to Jefferson County Regulation 1.07 include: (1) Changing the 
name of the regulation from ``Emissions During Startups, Shutdowns, 
Malfunctions and Emergencies'' to ``Excess Emissions During Startups, 
Shutdowns, and Upset Conditions;'' (2) clarifying that excess emissions 
from a process or process equipment due to startup, shutdown or upset 
condition shall be deemed in violation of the applicable emission 
standards; (3) removing the authority of the District to grant 
discretionary exemptions from compliance with SIP emission standards 
during SSM events; (4) augmenting the source excess emission reporting 
requirements to assist the District in evaluating whether ambient 
standards and goals have been exceeded and whether enforcement actions 
are needed to protect public health and welfare; and (5) removing the 
provisions that created exemptions for excess emissions during 
emergencies based upon factors comparable to an affirmative defense.
---------------------------------------------------------------------------

    \2\ The District's Regulatory Impact Analysis for the June 21, 
2005, changes to the SSM rule references the following memoranda as 
part of the basis for the revisions to its SSM rule: ``Policy on 
Excess Emissions During Startup, Shutdown, Maintenance, and 
Malfunctions,'' Kathleen M. Bennett, September 28, 1982; ``Policy on 
Excess Emissions During Startup, Shutdown, Maintenance, and 
Malfunctions,'' Kathleen M. Bennett, February 15, 1983; and ``State 
Implementation Plans: Policy Regarding Excess Emissions During 
Malfunctions, Startup, and Shutdown,'' Steven A. Herman, September 
20, 1999.
---------------------------------------------------------------------------

III. What is EPA's evaluation of the revisions to the Jefferson County 
SSM Rule?

    EPA has evaluated the revised version of the Jefferson County SSM 
rule submitted as part of the March 22, 2011, SIP submission from KDAQ 
on behalf of the District. Based upon this evaluation, EPA believes 
that the District has made several significant changes that make the 
Jefferson County SSM rule consistent with CAA requirements and with EPA 
guidance on SIP provisions relevant to the treatment of excess 
emissions during SSM events.

[[Page 29685]]

    First, the District has explicitly provided that excess emissions 
from sources due to startup, shutdown, or upset (i.e., malfunction) 
events are not exempt from compliance with applicable emission limits. 
Revised Section 2.2 of the Jefferson County SSM rule clearly provides 
that excess emissions during such events ``shall be deemed in violation 
of the applicable emission standard.'' This provision is consistent 
with EPA's longstanding interpretation of the CAA to prohibit SIP 
provisions that include any exemptions for excess emissions during SSM 
events and requiring that such emissions be treated as violations.\3\
---------------------------------------------------------------------------

    \3\ See, e.g., ``State Implementation Plans (SIPs): Policy 
Regarding Excess Emissions During Malfunctions, Startup, and 
Shutdown,'' sent by Steven A. Herman, Assistant Administrator for 
Enforcement and Compliance Assurance, and Robert Perciasepe, 
Assistant Administrator for Air and Radiation, to the Regional 
Administrators, Regions I-X, on Sept. 20, 1999.
---------------------------------------------------------------------------

    Second, the District has substantially revised the Jefferson County 
SSM rule in order to alter provisions that previously had the effect of 
providing an exemption for emissions during SSM events through the 
exercise of director's discretion by the District. The prior version of 
the rule contained factors that the District could consider in the 
decision whether or not to grant such a discretionary exemption. 
Revised Section 2.3 removes the authority of the District to grant 
discretionary exemptions from compliance with SIP emission standards 
and in its place provides an ``enforcement discretion'' provision that 
provides specific factors for state personnel in their own exercise of 
enforcement discretion for violations related to startup, shutdown, and 
upset events. These factors are intended to apply only to the District 
and do not affect EPA enforcement or citizen enforcement--both of which 
are separately authorized by the CAA.\4\ These factors include 
consideration of the duration and frequency of the emissions; 
operation/maintenance practices; whether there is a recurring pattern; 
certain public health impacts associated with the excess emissions, 
among other factors. Notably, these factors are also not intended to, 
and do not, operate as an affirmative defense.\5\ This revised 
provision is consistent with EPA's longstanding interpretation of the 
CAA to permit SIP provisions that address the exercise of enforcement 
discretion by state personnel, so long as they do not impinge upon the 
enforcement discretion of EPA or citizens.\6\
---------------------------------------------------------------------------

    \4\ On May 9, 2013, Jefferson County provided EPA with a letter 
clarifying and confirming that the factors included in Regulation 
1.07, Section 2.3, are intended to be discretionary factors that 
Jefferson County may consider as part of its own enforcement 
discretion and that the rule does not intend to or purport to apply 
to any other agency or the public. This letter is a part of the 
basis for EPA's action upon the SIP submission and part of the 
record for the action to be appropriately reflected in the CFR.
    \5\ EPA notes that revised Section 3.4 of the Jefferson County 
SSM rule provides that either startup or shutdown that is 
necessitated by an upset shall be considered part of the upset. 
Provision 2.3, which sets forth enforcement discretion factors, 
refers to Section 3.6 and 4.4 and thus the Jefferson County SSM rule 
treats startups following a malfunction event in the same manner as 
it treats all excess emissions for purposes of enforcement 
discretion. In the context of an enforcement discretion provision, 
as opposed to an affirmative defense provision for malfunctions, the 
Jefferson County SSM rule is consistent with the CAA and EPA's 
policy and guidance.
    \6\ See ``Policy on Excess Emissions During Startup, Shutdown, 
Maintenance, and Malfunctions,'' sent by Kathleen M. Bennett, 
Assistant Administrator for Air, Noise, and Radiation, to the 
Regional Administrators, Regions I-X on Feb. 15, 1983 (indicating 
the CAA would allow appropriately drawn enforcement discretion 
provisions in SIPs).
---------------------------------------------------------------------------

    Third, the District has also substantially revised the Jefferson 
County SSM rule to remove provisions that previously included specific 
treatment for excess emissions during emergencies. The prior version of 
the rule included provisions that together appeared to provide an 
exemption for excess emissions that occurred during emergencies, if the 
source could meet certain factors that were structured as an 
affirmative defense. The District has removed the definition of 
``emergency'' that previously appeared in Section 1.1 and removed the 
provisions applicable to emergencies in Section 5. The prior version of 
the Jefferson County SSM rule could have operated to exempt excess 
emissions during such events, and to provide a bar not just to monetary 
penalties, but also a bar to injunctive relief for the resulting 
violations of SIP emission standards. Moreover, the factors for the 
affirmative defense were not consistent with EPA's guidance for 
affirmative defense provisions for malfunctions.\7\ Removal of these 
provisions from the Jefferson County SSM rule is thus consistent with 
EPA's longstanding guidance concerning SIP provisions, both with 
respect to exemptions for excess emissions and with respect to 
affirmative defense provisions that would be consistent with CAA 
requirements.
---------------------------------------------------------------------------

    \7\ See ``State Implementation Plans (SIPs): Policy Regarding 
Excess Emissions During Malfunctions, Startup, and Shutdown,'' sent 
by Steven A. Herman, Assistant Administrator for Enforcement and 
Compliance Assurance, and Robert Perciasepe, Assistant Administrator 
for Air and Radiation, to the Regional Administrators, Regions I-X, 
on Sept. 20, 1999 (indicating that the CAA would allow appropriately 
drawn affirmative defense provisions in SIPs).
---------------------------------------------------------------------------

    Fourth, the District has revised the provisions of the Jefferson 
County SSM rule to update and expand the notification requirements for 
sources in the event of excess emissions related to startup, shutdown, 
and upset conditions. These provisions relate to the timing and nature 
of notification that the source is required to make to the District and 
may be germane to the District's exercise of enforcement discretion 
under revised Section 2.3. EPA believes that these updated notification 
provisions will likely enhance compliance and enforcement efforts 
within the Jefferson County area and that they otherwise are consistent 
with CAA requirements because they do not purport to affect the 
exercise of enforcement discretion by EPA or other parties.
    Finally, the District substantially revised the Jefferson County 
SSM rule with respect to ``extended'' malfunctions and emergencies. 
Section 9 of the prior version of the rule appeared to allow sources to 
continue to operate for extended periods of time in the event of a 
malfunction or emergency, without legal consequence, so long as the 
source obtained prior authorization from the District. Revised Section 
5 of the rule now makes unequivocally clear that, even if the District 
authorizes continued operation during such an event following a 
specified process, the excess emissions that occur during that extended 
period of time remain violations of the applicable SIP emission 
standards. The revised provision states that the authorization by the 
District ``shall neither constitute an affirmative defense for 
violations caused by excess emissions nor preempt the rights of the EPA 
or any person to take action under federal, state, or local law.'' EPA 
believes Revised Section 5 in conjunction with revised Section 2.2 thus 
makes clear that any excess emissions during such periods constitute 
violations of the applicable SIP emission standards and that the 
District, EPA, or others using the citizen suit provision of the CAA 
may still pursue appropriate enforcement action against the source. The 
revised provision is thus consistent with EPA's longstanding 
interpretation of the CAA to prohibit SIP provisions that include 
exemptions for excess emissions during SSM events and requiring that 
such emissions be treated as violations.
    EPA believes that the revisions to the Jefferson County SSM rule 
are consistent with the requirements of both section 110(l) and section 
193. Under

[[Page 29686]]

section 110(l), EPA is prohibited from approving any SIP revision that 
would interfere with any applicable requirement concerning attainment 
and reasonable further progress or any other applicable requirements of 
the CAA. In this action, EPA believes that the revisions do not 
interfere with such requirements and in fact strengthen the existing 
SIP by removing or revising various provisions related to excess 
emissions during SSM events that included automatic exemptions, 
director discretion exemptions, affirmative defense provisions, and 
other provisions that were inconsistent with CAA requirements and would 
have interfered with effective enforcement of the SIP. Because all of 
these changes are improvements to the prior version of the Jefferson 
County SSM rule, and because they are themselves consistent with the 
requirements of the CAA as interpreted in EPA guidance for SIP 
provisions, EPA is proposing to find that the revision is consistent 
with the requirements of section 110(l).
    Similarly, CAA section 193 prohibits EPA from approving SIP 
revisions to certain SIP control requirements in effect prior to 
November 15, 1990, unless the modification insures equivalent or 
greater emission reductions. The revision at issue in this action does 
pertain to control requirements that, at least in part, predate 
November 15, 1990, and thus compliance with section 193 is required. 
Because all of the revisions are improvements to the prior version of 
the Jefferson County SSM rule, and because the revised provisions are 
themselves consistent with the requirements of the CAA as interpreted 
in EPA guidance for SIP provisions, EPA is proposing that the revision 
is also consistent with the requirements of section 193. As a result of 
the improved effectiveness of the enforcement program associated with 
emissions during SSM, and the explicit determination that such 
emissions are violations of applicable emission limits, the revision is 
expected to produce equivalent or greater emission reductions and is 
thus consistent with CAA section 193.
    Based upon the foregoing analysis, EPA is proposing to approve the 
changes to the Jefferson County SSM rule contained in the March 22, 
2011, SIP submission from KDAQ on behalf of the District. EPA has 
determined that the specific changes to the rule are consistent with 
CAA requirements for SIP provisions that address excess emissions 
during SSM events, and with EPA guidance concerning such provisions. 
EPA requests comment on this proposal, and in particular requests 
comments on its view that the revisions to the Jefferson County SSM 
rule are consistent with CAA requirements for SIP provisions.
    EPA notes that in a separate rulemaking action, published on 
February 22, 2013, EPA identified several deficiencies associated with 
the Jefferson County SSM rule including: (1) the rule did not consider 
all excess emissions above SIP emission limits to be ``violations;'' 
(2) the rule included insufficiently bounded director's discretion 
provisions regarding whether an excess emissions event constituted a 
violation and thus creating impermissible discretionary exemptions from 
SIP emission limits; (3) the rule provided an impermissible exemption 
for excess emissions that occur during ``emergencies;'' and (4) the 
rule contained affirmative defense provisions that are not consistent 
with CAA requirements. See 78 FR 12460, 12507-12508. Today's action 
proposing approval of Jefferson County's revised SSM rule is separate 
from the February 22, 2013, action. EPA's action in this proposal does 
not reopen the public comment period associated with the separate 
February 22, 2013, action; nor does today's action purport to revise or 
amend that separate proposed action. EPA will be taking a separate 
final action on the February 22, 2013, proposed rulemaking. Today's 
action only proposes to approve the revised Jefferson County SSM Rule 
into the SIP as consistent with the CAA and CAA policy and guidance, 
for the reasons explained above.

IV. Why is EPA proposing this action and what is the effect of this 
proposed action?

    The purpose of today's action is to propose approval of changes to 
Regulation 1.07 in the Jefferson County portion of the Kentucky SIP. 
The District determined that the current SIP-approved rule required 
changes in light of EPA policy memoranda regarding excess emissions 
from stationary sources, and voluntarily provided a revision to KDAQ 
who submitted the revised rule to EPA for approval in 2011. The changes 
to Regulation 1.07, which are being proposed for inclusion into the SIP 
today, revise the Jefferson County SSM rule to make it consistent with 
the CAA.
    If finalized, today's action would approve part of the revision to 
the Jefferson County portion of the Kentucky SIP submitted by KDAQ, on 
behalf of the District, on March 22, 2011. Approval of this revision 
would change the name of the regulation to ``Excess Emissions During 
Startups, Shutdowns, and Upset Conditions;'' clarify that excess 
emissions due to startup, shutdown or upset condition shall be deemed 
in violation of the applicable emission standards; augment the source 
excess emission reporting requirements to improve air quality 
management; remove the authority of the District to grant discretionary 
exemptions from compliance with SIP emission standards during SSM 
events; remove the affirmative defense provision for emergencies; and 
explicitly state that the District's decision not to exercise its own 
enforcement discretion would not preempt enforcement by EPA or other 
parties. Today's action does not make any changes or propose any 
findings related to EPA's completely separate rulemaking action 
regarding the current SIP-approved version of the Jefferson County SSM 
rule proposed on February 22, 2013 (78 FR 12460).

V. Proposed Action

    EPA is proposing to approve the portion of Kentucky's March 22, 
2011, SIP revision pertaining to Jefferson County Regulation 1.07, 
``Emissions During Startups, Shutdowns, Malfunctions and Emergencies.'' 
This revision renames the regulation ``Excess Emissions During 
Startups, Shutdowns, and Upset Conditions'' and makes numerous changes 
to the Jefferson County SSM rule to bring it into compliance with the 
CAA and EPA guidance regarding SIP provisions for the correct treatment 
of excess emissions from sources during SSM events.

VI. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
proposed action merely approves state law as meeting federal 
requirements and does not impose additional requirements beyond those 
imposed by Commonwealth law. For that reason, this proposed action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);

[[Page 29687]]

     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the Commonwealth, and EPA notes that it will not impose substantial 
direct costs on tribal governments or preempt tribal law.
