[EPA-R04-OAR-2009-0140; FRL-9789-6]

Approval and Promulgation of Air Quality Implementation Plans:
North Carolina; Control Techniques Guidelines and Reasonably Available
Control Technology

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve several State Implementation Plan
(SIP) revisions submitted to EPA by the State of North Carolina,
through the North Carolina Department of Environment and Natural
Resources (NC DENR), to address the nitrogen oxides (NOx) reasonably
available control technology (RACT) requirements for the North Carolina
portion of the Charlotte-Gastonia-Rock Hill, North Carolina-South
Carolina 1997 8-hour ozone nonattainment area (hereafter referred to as
the ``bi-state Charlotte Area''). The bi-state Charlotte Area for the
1997 8-hour ozone national ambient air quality standards (NAAQS)
includes six full counties and one partial county in North Carolina;
and one partial county in South Carolina. Additionally, EPA is
proposing to approve in part, and conditionally approve in part,
several SIP revisions to address the volatile organic compounds (VOC)
RACT requirements which include related control technology guidelines
(CTG) requirements. Together, these SIP revisions establish the RACT
requirements for sources located in the North Carolina portion of the
bi-state Charlotte Area. In a separate rulemaking, EPA has already
taken action on RACT and CTG requirements for the South Carolina
portion of the bi-state Charlotte Area. EPA has evaluated the proposed
revisions to North Carolina's SIP, and has made the preliminary
determination that they are consistent, with the exception of
applicability for some CTG VOC sources, with statutory and regulatory
requirements and EPA guidance.

I. Background

    On April 30, 2004, EPA designated the bi-state Charlotte Area as a
moderate nonattainment area with respect to the 1997 8-hour ozone
NAAQS.\1\ See 69 FR 23858. The bi-state Charlotte Area includes six
full counties and one partial county in North Carolina; and one partial
county in South Carolina. The North Carolina portion of the bi-state
Charlotte Area consists of Cabarrus, Gaston, Lincoln, Mecklenburg,
Rowan, Union and a portion of Iredell County which includes Davidson
and Coddle Creek Townships.\2\ The South Carolina portion of the bi-
state Charlotte Area consists of the portion of York County, South
Carolina that falls within the Rock Hill-Fort Mill Area Transportation
Study Metropolitan Planning Organization Area. As a result of this
designation, North Carolina and South Carolina were required to amend
their SIPs for their respective portions of the bi-state Charlotte Area
to satisfy the requirements of section 182 of the Clean Air Act (CAA or
Act). Today's action specifically addresses the North Carolina portion
of the bi-state Charlotte Area. EPA approved the RACT requirements for
the South Carolina portion of the bi-state Charlotte Area on November
28, 2011. See 76 FR 72844.
---------------------------------------------------------------------------

    \1\ Portions of the bi-state Charlotte Area were previously
designated as a moderate nonattainment area for the 1-hour ozone
NAAQS. The Area was subsequently redesignated to attainment for the
1-hour ozone NAAQS, and a maintenance plan was approved into the
North Carolina SIP. The original Charlotte-Gastonia, North Carolina
1-hour moderate ozone nonattainment area consisted of Mecklenburg
and Gaston counties in North Carolina.
    \2\ Effective July 20, 2012, EPA designated one full county and
six partial counties in the bi-state Charlotte area as a marginal
nonattainment area for the 2008 8-hour ozone NAAQS. Today's proposed
actions regarding RACT are not related to requirements for the 2008
8-hour ozone NAAQS.
---------------------------------------------------------------------------

A. Statutory Requirements

    Section 182(b)(2) of the CAA requires states to adopt RACT rules
for all areas designated nonattainment for ozone and classified as
moderate or above. The three parts of the section 182(b)(2) RACT
requirements are: (1) RACT for sources covered by an existing CTG
(i.e., a CTG issued prior to enactment of the 1990 amendments to the
CAA); (2) RACT for sources covered by a post-enactment CTG; and (3) all
major sources not covered by a CTG (i.e., non-CTG sources). Pursuant to
40 CFR 51.165, a major source for a moderate ozone area is a source
that emits 100 tons per year (tpy) or more of VOC or NOX.
See Section I. B. below for further information regarding major
sources.
    A CTG document is guidance issued by EPA which, as a result of CAA
section 182(b)(2), triggers a responsibility for states to submit, as
part of their SIPs, RACT rules for stationary sources of VOC that are
covered by the CTG. EPA defines RACT as ``the lowest emission limit
that a particular source is capable of meeting by the application of
control technology that is reasonably available considering
technological and economic feasibility.'' See 44 FR 53761, 53762
(September 17, 1979). Each CTG category includes a ``presumptive norm''
or ``presumptive

RACT'' that EPA believes satisfies the definition of RACT.
    If a state submits a RACT rule that is consistent with presumptive
RACT, the state does not need to submit additional support to
demonstrate that the rule meets the CAA's RACT requirement. However, if
the state decides to submit an alternative emission limit or level of
control for a source or source category for which there is a
presumptive RACT, the state must submit independent documentation as to
why the rule meets the statutory RACT requirement.
    As mentioned above section 182(b)(2) of the CAA addresses moderate
and above areas for the 1-hour ozone NAAQS. Further clarification of
the RACT requirements for areas classified as moderate or above for the
1997 8-hour ozone NAAQS is provided in EPA's regulations.\3\ See 40 CFR
51.912.
---------------------------------------------------------------------------

    \3\ On July 18, 1997, EPA promulgated a revised 8-hour ozone
NAAQS of 0.08 parts per million--also referred to as the 1997 8-hour
ozone NAAQS. On April 30, 2004, EPA designated areas as
unclassifiable/attainment, nonattainment and unclassifiable for the
1997 8-hour ozone NAAQS. In addition, on April 30, 2004, as part of
the framework to implement the 1997 8-hour ozone NAAQS, EPA
promulgated an implementation rule in two phases (Phase I and II).
The Phase I Rule (effective on June 15, 2004), provided the
implementation requirements for designated areas under subpart 1 and
subpart 2 of the CAA. See 69 FR 23951. EPA's Phase II Rule,
finalized on November 29, 2005, addressed control and planning
requirements as they applied to areas designated nonattainment for
the 1997 8-hour ozone NAAQS such as RACT, reasonably available
control measures (RACM), reasonable further progress, modeling and
attainment demonstrations, new source review, and the impact to
reformulated gas for the 1997 8-hour ozone NAAQS transition. See 70
FR 71612.
---------------------------------------------------------------------------

    The CTG established by EPA are guidance to the states and only
provide recommendations. A state can develop its own strategy for what
constitutes RACT for the various CTG categories, and EPA will review
that strategy in the context of the SIP process and determine whether
it meets the RACT requirements of the CAA and its implementing
regulations. If no major sources of VOC or NOX emissions
(each pollutant should be considered separately) in a particular source
category exist in an applicable nonattainment area, a state may submit
a negative declaration for that category.
    In addition, section 183(e) of the CAA directs EPA to: (1) List for
regulation those categories of products that account for at least 80
percent of the VOC emissions, on a reactivity-adjusted basis, from
consumer and commercial products in ozone nonattainment areas; and (2)
divide the list of categories to be regulated into four groups. EPA
published the initial list, following the 1990 CAA Amendments, in the
Federal Register on March 23, 1995 (60 FR 15264), and has revised the
list several times. See 71 FR 28320 (May 16, 2006), 70 FR 69759
(November 17, 2005), 64 FR 13422 (March 18, 1999), 63 FR 48792
(September 11, 1998). As authorized by CAA section 183(e)(3)(C), EPA
chose to issue CTG in lieu of regulations for each listed product
category. See 73 FR 58481 (October 7, 2008) (Group IV CTG); 72 FR 57215
(October 9, 2007) (Group III CTG); and 71 FR 58745 (October 5, 2006)
(Group II CTG).

B. Requirements for RACT Analysis for Major Sources

    Section 172(c)(1) of the CAA requires SIPs to provide for the
implementation of all RACM as expeditiously as practicable. A subset of
RACM is RACT, which relates specifically to stationary point sources.
Section 182(b)(2) of the CAA requires RACT rules be adopted for all
point sources of VOC and NOX with potential to emit at least
100 tpy or greater.\4\ \5\
---------------------------------------------------------------------------

    \4\ The potential to emit threshold is based on an area's
nonattainment designation classification. Section 182 of the CAA and
40 CFR 51.912(b) define ``major source'' for ozone nonattainment
areas to include sources which emit or which have the potential to
emit 100 tpy or more of VOC or NOX (ozone precursors) in
areas classified as ``marginal'' or ``moderate,'' 50 tpy or more of
these ozone precursors in areas classified as ``serious,'' 25 tpy or
more of these ozone precursors in areas classified as ``severe,''
and 10 tpy or more of these ozone precursors in areas classified as
``extreme.'' The bi-state Charlotte Area is a moderate nonattainment
area.
    \5\ Section 182(b)(2) also requires that all CTG source category
sources, including those with less than 100 tpy emissions meet RACT.
CTG sources are addressed later in this document.
---------------------------------------------------------------------------

C. Regulatory Schedule for Implementing CTG

    CTG categories that were established in 1978 ultimately were
required to be adopted by the states by 1990 (see schedule below for
details). CAA section 182(b)(2) provides that a CTG issued after 1990
must specify the date by which a state must submit a SIP revision in
response to the CTG. States were required to have the pre-1990 CAA CTG
categories and post-1990 CAA CTG categories for applicable areas
addressed in their SIPs according to the following schedule:

                  additional CTG categories    1980. EPA initially
                  were issued in 1978 (1 of    approved most of these
                  those (vegetable oil) was    rules into the state
                  rescinded).                  SIPs. Subsequently, EPA
                                               reviewed these state
                                               rules to see if they were
                                               technically adequate and
                                               if they met national
                                               standards for national
                                               consistency. Based on
                                               this review, EPA issued
                                               the RACT fix-ups in 1987
                                               (See general preamble (57
                                               FR 13498, April 16,
                                               1992)). In 1988, EPA
                                               published a technical
                                               document to address
                                               technical inadequacies
                                               found in these state

                                               of national consistency.
                                               States were required to
                                               adopt revised rules by
                                               1990. Congress

II. Analysis of the North Carolina's Submittals

    NC DENR submitted final SIP revisions on October 14, 2004, April 6,
2007, June 15, 2007, January 31, 2008, November 19, 2008, September 18,
2009, February 3, 2010, April 6, 2010, and November 9, 2010, to EPA for
review and approval into the North Carolina SIP. North Carolina's SIP
revisions include changes made by North Carolina to its Air Quality
Rules, found at Chapter15A NCAC 02D, and include changes to NC DENR's
NOX and VOC rules, including its NOX and VOC RACT
requirements. A brief description of each North Carolina SIP revision
submitted to meet NOX and VOC RACT requirements is provided
in Section II. A. of this rulemaking. Section II. B. of this rulemaking
provides EPA's analysis of how major sources for NOX in the
Area meet RACT requirements. Section II. C. of this rulemaking provides
EPA's analysis for the individual rules being changed by North Carolina
to meet NOX and VOC RACT requirements.
    Today, EPA is proposing to approve the portions of five of the
aforementioned SIP revisions as they relate to RACT requirements for
the North Carolina portion of the bi-state Charlotte Area (hereafter
referred to as ``the Area'').\6\ In addition to the SIP revisions, or
portions of SIP revisions for which EPA is proposing approval, NC DENR
submitted a letter on August 30, 2012, requesting that EPA
conditionally approve portions of previously-submitted SIP revisions as
they relate to VOC RACT and CTG requirements.7 8
Specifically, NC DENR committed to include appropriate applicability
thresholds for VOC RACT for all sources addressed by CTG in the Area. A
copy of NC DENR's letter is provided in the docket for today's
rulemaking. Consequently, EPA is proposing to conditionally approve
portions of five of the aforementioned SIP revisions as they relate to
VOC RACT and CTG requirements for the Area. Comprehensively, these SIP
revisions address NOX RACT, VOC RACT and CTG requirements
for the Area.\9\
---------------------------------------------------------------------------

    \6\ SIP revisions submitted on April 6, 2007, June 15, 2007,
January 31, 2008, November 19, 2008, February 3, 2010, and April 6,
2010,
    \7\ SIP revisions submitted on October 14, 2004, April 6, 2007,
January 31, 2008, September 18, 2009, and November 9, 2010.
    \8\ Additional information regarding the conditional approval is
found in Section III of this action.
    \9\ South Carolina met the RACT requirements for the South
Carolina portion of the bi-state Charlotte Area.
---------------------------------------------------------------------------

A. Summary of North Carolina's SIP Submittals

a. October 14, 2004, SIP Submittal
    On October 14, 2004, North Carolina submitted a SIP revision
amending several rules. The VOC applicability Rule 15A NCAC 2D .0902,
was amended to: (1) Specify what sources Rule .0902 does not apply to;
(2) change the rule to address attainment for the 1-hour ozone NAAQS
and nonattainment for the 8-hour ozone NAAQS; and (3) exclude emissions
from startup or shutdown operations. Today, EPA is proposing to
conditionally approve all changes to Rule 15A NCAC 2D .0902, with the
exception of North Carolina's amendment to exclude emissions from
startup or shutdown operations (15A NCAC 2D .0902 (b)(3)).\10\
---------------------------------------------------------------------------

    \10\ In this action, EPA is not proposing to approve or
disapprove any existing state provisions with regard to excess
emissions during start up, shut down and malfunction (SSM) of
operations at a facility. EPA believes that a number of states have
SSM provisions which are contrary to the CAA and existing EPA
guidance, ``State Implementation Plans: Policy Regarding Excess
Emissions During Malfunctions, Startup, and Shutdown'' (September
20, 1999), and the Agency plans to address such state regulations in
the future. In the meantime, EPA encourages any state having
deficient SSM provisions to take steps to correct them as soon as
possible.
---------------------------------------------------------------------------

    Additionally, in the October 14, 2004, SIP revision, the rule which
applies to petroleum liquid storage in external floating roof tanks,
Rule 15A NCAC 2D .0933, was amended to clarify the seal requirements
for external floating roof tanks. Today, EPA is proposing to approve
all changes to Rule 15A NCAC 2D .0933 as provided in North Carolina's
October 14, 2004, SIP revision.
    The October 14, 2004, SIP revision, also amends NOX
Rules 15A NCAC 2D .1404, 1409, .1416 through .1419 and .1422. Rule
.1404, .1409, 1418 and .1422 were amended to clarify monitoring
requirements, stationary internal combustion engine requirements,
offsets for new electric generating units, large boilers and large
internal combustion engines, and clarifying the use of compliance
supplement pool credits, respectively. NC DENR requested approval of
revisions to Rules .1416, .1417, and .1419 regarding emission
allocations for utility companies and large combustion sources, and
regarding nitrogen oxide budget trading program but subsequently
repealed these rules and submitted them for approval on November 19,
2008. The November 19, 2008, request for approval of the repeals
replaces the October 14, 2004, request for rule revision approval.
Today, EPA is proposing to approve all changes to Rules .1404, .1409,
.1418 and .1422 provided in North Carolina's October 14, 2004, SIP
revision. The changes to Rules .1416, .1417 and .1419 are replaced by
the November 19, 2008, submittal.
    EPA is not taking action on any of the remaining rule changes in
the October 14, 2004, SIP revision.\11\ These remaining rule changes
will be addressed in a separate action.
---------------------------------------------------------------------------

    \11\ The remaining rule changes that EPA is not acting on in
this action include 15A NCAC 2D .0101, .0521, 15A NCAC 2Q .0806,
.0809, 15A NCAC 2D .1901 through .1904 and .1906. These rules
address Air Pollution Control Definitions, Emission Control
Standards, Permitting Requirements and Open Burning and are not
required to meet RACT for the 1997 8-hour ozone standard.
---------------------------------------------------------------------------

b. Summary of the April 6, 2007, SIP Submittal
    On April 6, 2007, North Carolina submitted a SIP revision to
address RACT and meet the EPA requirements for a full SIP revision for
the bi-state Charlotte Area ozone nonattainment area to address the
1997 8-hour ozone NAAQS. Specifically, the VOC applicability rule, 15A
NCAC 02D .0902, and NOX applicability rule 15A NCAC 02D
.1402, were amended to require facilities with the potential to emit
100 tpy or more of VOC or NOX to comply with RACT
requirements for VOC or NOX in the bi-state Charlotte
nonattainment area for the 1997 8-hour ozone NAAQS. The VOC Compliance
Schedule Rule 15A NCAC 02D .0909, and the NOX Compliance
Schedule Rule 15A NCAC 02D .1403, added compliance schedules for the
facilities to comply with RACT requirements. Today, EPA is proposing to
approve all changes to rules 15A NCAC 02D .1402, and .1403, and is
proposing to conditionally approve all changes to rules 15A NCAC 02D
.0902 and .0909, that were included as part of the April 6, 2007, SIP
revision.
c. Summary of the June 15, 2007, SIP Submittals
    The June 15, 2007, SIP revisions consisted of the attainment
demonstration, reasonable further progress (RFP) and the RACT
submissions related to the 1997 8-hour ozone NAAQS for the Area. On
December 19, 2008, North Carolina withdrew its attainment demonstration
that the NC DENR submitted on June 15, 2007. However, North Carolina
did not withdraw its submissions for RFP or RACT. See 74 FR 21550 (May
9, 2009). In a previous action, EPA approved North Carolina's RFP SIP
revision. See 77 FR 62159 (October 12, 2012). As a result, today's
action only addresses

North Carolina's RACT SIP for its portion of the bi-state Charlotte
Area. EPA has made the preliminary determination that North Carolina's
June 15, 2007, SIP revision, in combination with others addressed in
this rulemaking and previous rulemakings,\12\ meets RACT requirements,
and thus EPA is proposing to approve North Carolina's June 15, 2007,
RACT SIP revision.
---------------------------------------------------------------------------

    \12\ While North Carolina's June 15, 2007, submission references
VOC rules 15A NCAC 2D .0901 through .0960, and NOX rules
15A NCAC 2D .1402 through .1412, and 15A NCAC 2D .1415 through
.1422, the SIP revision did not provide amendments to these rules
for EPA approval. However, in its June 15, 2007, SIP revision North
Carolina is using these previously approved rules as demonstration
that they meet RACT requirements.
---------------------------------------------------------------------------

d. Summary of the January 31, 2008, SIP Submittal \13\
---------------------------------------------------------------------------

    \13\ The January 31, 2008, SIP revision also amended Rule 15A
NCAC 02Q .0207, ``Annual Emissions Reporting.'' In an action taken
on April 24, 2012, (77 FR 24382), EPA approved these revisions to
Rule 15A NCAC 02Q .0207.
---------------------------------------------------------------------------

    On January 31, 2008, North Carolina submitted a SIP revision to
address certain RACT requirements, and meet the EPA requirements for a
full SIP revision for the bi-state Charlotte Area ozone nonattainment
area to address the 1997 8-hour ozone NAAQS. Specifically, the VOC
Applicability Rule 15A NCAC 02D .0902 was amended to cover facilities
with the potential to emit between 50 and 100 tons of VOC per year in
Cabarrus, Gaston, Lincoln, Mecklenburg, Rowan, and Union Counties and
Davidson and Coddle Creek Townships in Iredell County. Additionally,
North Carolina's NOX Applicability Rule 15A NCAC 02D .1402,
was amended to describe the actions to be taken at facilities with the
potential to emit between 50 and 100 tons of NOX per year.
    At the time that the rules in North Carolina's January 31, 2008,
SIP revision were changed and submitted to EPA, the bi-state Charlotte
Area had not yet attained the 1997 8-hour ozone NAAQS, and there was a
possibility that EPA would have to reclassify the bi-state Charlotte
Area to a serious nonattainment area. North Carolina revised these
rules as a contingency for the bi-state Charlotte Area should this area
be reclassified from a ``moderate'' nonattainment area to a ``serious''
nonattainment for the 1997 8-hour ozone NAAQS.\14\ The bi-state
Charlotte Area subsequently attained the standard, and is currently a
moderate nonattainment area. The VOC Compliance Schedule Rule 15A NCAC
02D .0909, and NOX Compliance Schedule Rule 15A NCAC 02D.
1403 added compliance schedules for the facilities to comply with RACT
requirements should the bi-state Charlotte Area fail to attain and as a
result was reclassified as serious area.
---------------------------------------------------------------------------

    \14\ As provided for in the CAA, on May 31, 2011, North Carolina
was granted a 1 year extension of the attainment date (See 76 FR
31245), attained the standard prior to the extended attainment date,
was not reclassified to serious and continued to be a moderate area.
---------------------------------------------------------------------------

    EPA is now proposing to conditionally approve changes to VOC
Applicability Rule 15A NCAC 02D .0902, and VOC Compliance Schedule Rule
15A NCAC 02D .0909. Additionally EPA is proposing to approve the
remaining changes included in North Carolina's January 31, 2008, SIP
revision regarding NOX Applicability Rule 15A NCAC 02D
.1402, and NOX Compliance Schedule Rule 15A NCAC 02D .1403.
e. Summary of the November 19, 2008, SIP Submittal
    On November 19, 2008, North Carolina submitted a SIP revision to
address adoption of a new rule section (Section 15A NCAC 02D .2600)
that consolidated North Carolina's protocols with federal air source
testing methods from many rules located throughout North Carolina air
rules. Rule amendments to or repeals of Rules 15A NCAC 02D .0901, .0912
through .0916, .0932, .0939 through .0943, .0945 were also made to
cross-reference or be replaced by the new rule section 15A NCAC 02D
.2600. North Carolina's November 19, 2008, SIP revision also amends
Rule 15A NCAC 02D .1402 to remove reference to repealed NOX
SIP Call Rules and Rules 15A NCAC 02D .1407 through .1412, and .1415
through .1422.\15\
---------------------------------------------------------------------------

    \15\ These rules are repealed because CAIR replaced the
NOX Budget Trading Program for North Carolina.
---------------------------------------------------------------------------

    EPA is proposing to approve changes to Rules 15A NCAC 02D .0901,
.0912, .0932, .0943, .0945, .1402, and .1415. EPA is proposing to
approve the repeal of Rules 15A NCAC 02D .0913 through .0916, .0939
through .0942, and .1416 through .1422 as these provisions are no
longer necessary for North Carolina's SIP. EPA is not taking action on
any of the remaining rule changes in the November 19, 2008, SIP
revision.\16\
---------------------------------------------------------------------------

    \16\ The remaining rule changes that EPA is not acting on in
this action include 15A NCAC 02D .0501, .0529, .0535, .0536, .0542,
.0606, .0608, NCAC 2D .2609, .2610, .2611, .2616, .2617, .2618,
.2619, .2620, NCAC 02D .1110, .1203 through .1206, .1208, .1210, and
15A NCAC 02Q .0508, .0523, .0711, and .0902. These rules address
Emission Control Standards, Monitoring and Recordkeeping, Source
Testing unrelated to Ozone, Toxics, Incinerators, and Permitting,
and are not required to meet RACT for the 1997 8-hour ozone
standard. (While Rules NCAC 2D 1104 and NCAC 2Q .0903 were listed in
the submittal, North Carolina requested they not be approved into
the SIP).
---------------------------------------------------------------------------

f. Summary of the September 18, 2009, SIP Submittal \17\
---------------------------------------------------------------------------

    \17\ In a letter dated November 30, 2012, North Carolina
withdrew its request for EPA to approve Rule 15A NCAC 02D .0952,
Petitions for Alternative Controls for RACT into the SIP.
---------------------------------------------------------------------------

    On September 18, 2009, North Carolina submitted a SIP revision to
address certain RACT requirements. First, the VOC definitions Rule 15A
NCAC 02D .0901 was amended to include the definition of Stage I vapor
control. Second, the VOC Applicability Rule, 15A NCAC 02D .0902, was
amended to remove a subparagraph that refers to Rule 15A NCAC 02D
.0953, ``Vapor Return Piping for Stage II Vapor Recovery,'' as this
provision was repealed by the State. Third, the VOC Compliance Schedule
Rule, 15A NCAC 02D .0909, was amended to remove reference to Stage II
vapor recovery at Rules 15A NCAC 02D .0953, ``Vapor Return Piping for
Stage II Vapor Recovery,'' and 15A NCAC 02D .0954, ``Stage II Vapor
Recovery,'' as these provisions were repealed by the State.\18\ Fourth,
the ``Petition for Alternative Controls for RACT,'' Rule 15A NCAC 02D
.0952, was amended to remove reference to Stage II vapor recovery at
Rules 15A NCAC 02D .0953 and .0954 as these provisions were repealed by
the State.
---------------------------------------------------------------------------

    \18\ North Carolina also included a repeal of Rule 15A NCAC 02D
.0953, ``Vapor Return Piping for Stage II Vapor Recovery,'' and Rule
.0954, ``Stage II Vapor Recovery'' in its November 18, 2010, SIP
revision. These rules are not required for RACT. EPA will address
North Carolina's November 18, 2010, SIP revision as it pertains to
the repeal of these rules in a separate action.
---------------------------------------------------------------------------

    EPA is proposing to conditionally approve the changes in the
September 18, 2009, SIP revision related to Rules 15A NCAC 02D .0902
and .0909. Additionally, EPA is proposing to approve the changes to
Rules 15A NCAC 02D .0901 and .0952, as provided in North Carolina's
September 18, 2009, SIP revision. EPA is not taking action on any of
the remaining rule changes in the September 18, 2009, SIP revision.\19\
These remaining rule changes will be addressed in a separate action.
---------------------------------------------------------------------------

    \19\ The remaining rule changes that EPA is not acting on in
this action include 15A NCAC 2D, .0521, .0614, NCAC 2Q .0102, .0304,
and .0902. These rules address Air Pollution Control, Emission
Control Standards, Monitoring and Recordkeeping and Air Quality
Permit Procedures and are not required to meet RACT for the 1997 8-
hour ozone standard.
---------------------------------------------------------------------------

g. Summary of the February 3, 2010, SIP Submittal
    On February 3, 2010, North Carolina submitted a SIP revision to
address a number of different rule amendments

including a change to the NOx applicability Rule 15A NCAC 02D .1402.
Rule .1402 was amended to: (1) Add language to clarify which parts of
Rule Section .1400 apply to sources covered under Clean Air Interstate
Rules (CAIR), which replaced the NOx Budget Trading Program for North
Carolina; (2) clarify RACT requirements in nonattainment areas; and (3)
correct cross-reference errors.
    EPA is proposing to approve North Carolina's changes to Rule .1402,
as provided in the February 3, 2010, SIP revision. This is the only
rule amendment in North Carolina's February 3, 2010, SIP revision being
addressed in today's action. The remaining rule changes will be
addressed in a separate action.\20\
---------------------------------------------------------------------------

    \20\ The remaining rule changes that EPA is not acting on in
this action include 15A NCAC 02D, .0405, .0408 .0409, and .0410.
These rules address Ambient Air Quality Standards and are not
required to meet RACT for the 1997 8-hour ozone standard.
---------------------------------------------------------------------------

h. Summary of the April 6, 2010, SIP Submittal
    On April 6, 2010, North Carolina submitted a SIP revision to
address RACT, specifically to make a negative declaration for the
following four CTG categories: (1) Control of Volatile Organic Compound
Leaks from Petroleum refinery Equipment (EPA-450/2-78-036, 1978/06);
(2) Control of Refinery Vacuum Producing Systems, Wastewater
Separators, and Process Unit turnarounds (EPA-450/2-77-026, 1977/10);
(3) Control of Volatile Organic Compound Equipment Leaks from Natural
Gas/Gasoline Processing Plants (EPA-450/3-83-007, 1983/12); and (4)
Control Techniques Guidelines, for Shipbuilding and Ship Repair
Operations (Surface Coating) (61 FR-44050 8/27/96, 1996/08).
    As part of its analysis to support the negative declarations for
aforementioned CTG source categories, NC DENR reviewed its permits
files and emissions inventory information. After this review, NC DENR
determined that there are no stationary sources or emitting facilities
located in its portion of the bi-state Charlotte Area that are subject
to aforementioned CTG source categories. EPA is now proposing to
approve the negative declarations as provided in North Carolina's April
6, 2010, SIP revision.
i. Summary of the November 9, 2010, SIP Submittal \21\
---------------------------------------------------------------------------

    \21\ In a letter dated November 30, 2012, North Carolina
withdrew its request for EPA to approve Rule 15A NCAC 02D .0952,
``Petitions for Alternative Controls for RACT'' into the SIP.
---------------------------------------------------------------------------

    On November 9, 2010, North Carolina submitted a SIP revision
amending, adopting, and repealing various RACT rules. First, Rule 15A
NCAC 02D .0902, VOC Applicability was amended to extend the work
practice standards in Rule 15A NCAC 02D .0958 to all sources of VOC in
the State, and to clarify that all areas that become subject to the VOC
RACT rules shall continue to comply with those rules after the Area is
redesignated to attainment. Second, Rule 15A NCAC 02Q .0306, ``Permits
Requiring Public Participation;'' Rule 15A NCAC 02D .0909, ``Compliance
Schedules for Sources in Nonattainment Areas;'' Rule 15A NCAC 02D
.0951, ``Metal Furniture Coatings Rule;'' and 15A NCAC 02D .0952
``Petition for Alternative controls for RACT'' were amended to change
cross-references.
    Third, Rule 15A NCAC 02D .0922, ``Metal Furniture Coatings'' was
amended to control VOC emissions from metal furniture coatings by
establishing three alternatives. Fourth, Rule 15A NCAC 02D .0923,
``Surface Coating of Large Appliance Parts'' was amended to control VOC
emissions from large appliance coatings by establishing three
alternatives. Fifth, Rule 15A NCAC 02D .0935, ``Factory Surface Coating
of Flat Wood Paneling'' was amended to establish new emission limits
for inks, coatings and adhesives used by the flat wood paneling coating
facilities.
    Sixth, Rule 15A NCAC 02D .0961, ``Offset Lithographic Printing and
Letterpress Printing'' was adopted to control VOC emissions from
heatset inks, fountain solution and cleaning materials used in offset
lithographic printing operations, as well as VOC emissions from heatset
inks used in letterpress printing operations at the level sufficient
for RACT requirements. Seventh, Rule 15A NCAC 02D .0962, ``Industrial
Cleaning Solvents'' was adopted to define measures for controlling
emissions of VOC from the use, storage, and disposal of industrial
cleaning solvents. Eighth, Rule 15A NCAC 02D .0963, ``Fiberglass Boat
Manufacturing'' was adopted to control VOC emissions from open molding
resin and gel coat operations (pigmented gel coat, clear gel coat,
production resin, tooling gel coat, and tooling resin); resin and gel
coat mixing operations; and resin and gel coat application equipment
cleaning operations at the level sufficient for RACT requirements.
Ninth, Rule 15A NCAC 02D .0964, ``Miscellaneous Industrial Adhesives''
was adopted to control VOC emissions from miscellaneous industrial
adhesives; it establishes VOC emission limits based on application
processes (general adhesive application processes, specialty adhesive
application processes and adhesive primer application processes.)
    Tenth, Rule 15A NCAC 02D .0965, ``Flexible Package Printing'' was
adopted to provide equivalent VOC content limits, which can be met by
use of low VOC content materials or combinations of materials and
controls. Eleventh, Rule 15A NCAC 02D .0966, ``Paper, Film and Foil
Coatings'' was adopted to establish an overall VOC control efficiency
of 90 percent for each coating line along with emission limits that are
equivalent to 90 percent overall control. Twelfth, Rule 15A NCAC 02D
.0967, ``Miscellaneous Metal and Plastic Parts Coatings'' was adopted
to control VOC emissions from miscellaneous metal and plastic part
surface coatings. Finally, Rule 15A NCAC 02D .0968, ``Automobile and
Light-Duty Truck Assembly Coatings'' was adopted to establish VOC
emission limits based on application processes (general adhesive
application processes, specialty adhesive application processes, and
adhesive primer application processes).
    Additionally, in the November 9, 2010, SIP revision, North Carolina
repealed Rules 15A NCAC 02D .0917, ``Automobile and Light-duty Truck
Manufacturing;'' 15A NCAC 02D .0920 ``Paper Coating;'' 15A NCAC 02D
.0921, ``Fabric and Vinyl Coating;'' 15A NCAC 02D .0934, ``Coating of
Miscellaneous Metal Parts and Products;'' and 15A NCAC 02D .0936,
``Graphic Art'' because North Carolina adopted new rules to address all
of these categories.
    EPA is proposing to conditionally approve the changes to Rules 15A
NCAC 02D .0902, .0909, .0951, .0961 and .0962. Also, EPA is proposing
to approve the changes to Rules 15A NCAC 02D .0922, .0923, .0935,
.0952, .0963 through .0968, and 15A NCAC 02Q .0306. Further EPA is
proposing to approve the repeal of Rules 15A NCAC 02D .0917,
``Automobile and Light-duty Truck Manufacturing;'' 15A NCAC 02D .0920,
``Paper Coating;'' 15A NCAC 02D .0921, ``Fabric and Vinyl Coating;''
15A NCAC 02D .0934, ``Coating of Miscellaneous Metal Parts and
Products;'' and 15A NCAC 02D .0936, ``Graphic Art.'' The remaining rule
changes in the November 9, 2010, SIP revision will be addressed in a
separate action.\22\
---------------------------------------------------------------------------

    \22\ The remaining rule changes that EPA is not acting on in
this action include NCAC 2Q, .0306. This rule addresses permit
requirements and is not required to meet RACT for the 1997 8-hour
ozone standard.
---------------------------------------------------------------------------

B. RACT Analysis for Major Sources for NOx

    In the mid 1990s, North Carolina's Division of Air Quality
completed a

technical analysis and determined that the entire state is NOx limited
\23\ and that the control program for reducing ozone should therefore
be focused on NOx emission reductions. Consistent with this finding,
North Carolina pursued a number of regulatory efforts to reduce NOx
statewide, several of which were directed at Electricity Generating
Unit (EGU) emissions. Specifically, NC DENR adopted measures to comply
with the NOx SIP Call rule and the General Assembly passed the Clean
Smokestacks Act (CSA). In addition NC DENR adopted rules to implement
CAIR. These programs, which are described further below, substantially
lowered NOx emissions in the bi-state Charlotte Area.
---------------------------------------------------------------------------

    \23\ NOx and VOC are precursors to ozone. NOx limited is a term
that describes an area in which naturally occurring VOCs are so high
that a reduction of manmade VOC does not measurably reduce ozone.
Therefore, a focus is placed on NOx reductions instead of a
combination of NOx and VOC reduction.
---------------------------------------------------------------------------

    In October 1998, EPA made a finding of significant contribution of
NOx emissions from certain states and published a rule that set ozone
season NOx budgets for the purpose of reducing regional transport of
ozone (63 FR 57356). This rule, referred to as the NOx SIP Call rule,
called for, among other things, ozone season controls to be put on
utility and industrial boilers, as well as internal combustion engines
in 22 states in the Eastern United States. As noted above, in October
2000, the North Carolina Environmental Management Commission adopted
similar rules requiring these reductions. When the North Carolina's NOx
SIP Call rule \24\ was adopted NC DENR concluded that the NOx SIP Call
would reduce summertime NOx emissions from power plants and other
industries by 68 percent by 2006. As part of the rulemaking and
consistent with EPA guidance, the North Carolina Environmental
Management Commission established a NOx trading program, allowing
sources to buy credits to meet their NOx budget as opposed to actually
installing controls. The emission budgets were to be met by the
beginning of 2004.
---------------------------------------------------------------------------

    \24\ This was federally approved into the SIP. See 67 FR 78987,
December 27, 2002.
---------------------------------------------------------------------------

    As mentioned above, in June 2002, the North Carolina General
Assembly enacted the CSA.\25\ CSA reduces NOx emissions beyond the
requirements of the NOx SIP Call rule and required coal-fired power
plants to reduce annual NOx emissions by 78 percent by 2009.
---------------------------------------------------------------------------

    \25\ This was federally-approved into the SIP on September 26,
2011. See 76 FR 59250.
---------------------------------------------------------------------------

    In response to the EPA's CAIR, the NC DENR developed a state
version of CAIR. Under EPA's rule, North Carolina is distributed a
statewide budget for NOX. These NOX allowances,
in turn, have been allocated to the affected facilities in North
Carolina by the NC DENR. For the most part, the rules incorporate EPA's
model rule. NC DENR adopted North Carolina's CAIR on March 9, 2006, and
the rule became effective July 1, 2006.
    On November 29, 2005 (70 FR 71612), EPA published an ozone
implementation rule to address nonattainment SIP requirements for the
1997 8-hour ozone NAAQS (the ``Phase 2 Ozone Implementation Rule'').
The Phase 2 Ozone Implementation Rule addressed various statutory
requirements, including the requirement for RACT level controls for
sources located within nonattainment areas generally, and controls for
NOX emissions from EGUs in particular. Through the Phase 2
Ozone Implementation Rule, EPA also provided its determination that the
regional NOX emissions reductions that result from either
the NOX SIP Call or CAIR would meet the NOX RACT
requirement for EGUs located in states included within the respective
NOX SIP Call or the CAIR geographic regions. Thus, EPA
concluded that: ``[t]he State need not perform a NOX RACT
analysis for sources subject to the State's emission cap-and-trade
program where the cap-and-trade program has been adopted by the State
and approved by EPA as meeting the NOX SIP Call requirements
or, in States achieving the CAIR reductions solely from electric
generating units (EGUs), the CAIR NOX requirements.''\26\
Based on the then existing EPA guidance, NC DENR concluded that the
NOX SIP Call rule, the CSA, and CAIR, in aggregate,
sufficiently addressed the implementation of RACT for point sources.
---------------------------------------------------------------------------

    \26\ See Phase 2 Ozone Implementation Rule, 70 FR 71617.
---------------------------------------------------------------------------

    In November 2008, several parties challenged EPA's Phase 2 Ozone
Implementation Rule. In particular, they challenged EPA's determination
that compliance with the NOX SIP Call and/or CAIR could
satisfy NOX RACT requirements for EGUs in nonattainment
areas and EPA's determination that compliance with CAIR could satisfy
NOX RACT for EGUs in ozone nonattainment areas. As a result
of this litigation, the court decided that the provisions in the Phase
2 Ozone Implementation Rule providing that a state need not perform (or
submit) a NOX RACT analysis for EGU sources subject to a
cap-and-trade program that meets the requirements of the NOX
SIP Call were inconsistent with the statutory requirements of section
172(c)(1).\27\ The court specifically held that the Phase 2 Ozone
Implementation Rule allowing use of the NOX SIP call to
constitute RACT without any locally applicable analysis regarding the
equivalence of NOX SIP Call and RACT reductions: ``Is
inconsistent with the Clean Air Act * * * in allowing participation in
a regional cap-and-trade program to satisfy an area-specific statutory
mandate.'' The court emphasized that: ``The RACT requirement calls for
reductions in emissions from sources in the area * * * [and that]
reductions from sources outside the nonattainment area do not satisfy
the requirement * * * [a]ccordingly, participation in the
NOX SIP call would constitute RACT only if participation
entailed at least RACT-level reductions in emissions from sources
within the nonattainment area.'' In view of its decision in North
Carolina v. EPA, in which the Court had previously remanded CAIR, the
court deferred consideration of the litigant's challenge to the Phase 2
Ozone Implementation Rule insofar as they related to the CAIR program.
In light of the above, as well as a 2007 petition for reconsideration
that EPA granted on this issue as it pertains to CAIR,\28\ EPA is
proposing in this action to not approve the presumption or
determination that CAIR or the NOX SIP Call constitutes RACT
for EGU sources in the Area. However, after evaluating controls at
individual point sources, EPA has determined that the point sources in
the area have implemented RACT. This analysis is included below.

    NC DENR identified six facilities in the North Carolina portion of
the bi-state Charlotte Area that are or were major sources of
NOX. Table 1 summarizes their emissions in 2003 and in 2011.
NOX controls installed on these facilities have resulted in
an average of 69 percent reduction across the bi-state Charlotte Area.

    Three of the facilities, Duke Energy Buck Steam Station, and Duke
Energy Riverbend and Kannapolis Energy Partners have shut down or plan
to shut down by 2015. Kannapolis Energy Partners is no longer in
operation. Duke Buck and Riverbend are shutting down these units
pursuant to conditions in state issued prevention of significant
deterioration permits and in order to comply with the provisions of
North Carolina's CSA. Because of the time necessary to install
additional controls and the limited remaining useful life between now
and 2015 for the two operating facilities (Duke Energy Buck Steam
Station, and Duke Energy Riverbend), a cost effectiveness analysis
based on one or two years of operation would preclude any additional
controls from being considered RACT.
    Two of the facilities, Rowan County Power and Duke Energy Lincoln,
have been through a BACT analysis and the controls adopted for BACT are
consistent with or more stringent than those that would be required for
RACT. Duke's G.G. Allen Plant has installed SNCR on two units and a
two-tiered LOFIR combustion controls on the remaining three units to
achieve NOx emissions reductions beyond those normally
achieved from Low NOX burners at Duke's G.G. Allen Plant.
    In aggregate, after the planned shutdowns occur, the bi-state
Charlotte Area will have reduced NOX emissions by 77 percent
from 2003 NOX emission levels. Because each of the units has
installed NOX controls to meet BACT requirements, or to
comply with existing source NOX requirements such as CAIR,
the NOX SIP call rule or CSA requirements or is scheduled to
be shutdown, EPA has concluded that the reductions in place at these
facilities in the bi-state Charlotte Area have resulted, in aggregate,
in at least RACT-level reductions in the bi-state Charlotte Area. Thus,
EPA is now taking action to approve North Carolina's rule revisions as
meeting NOX RACT requirements for the bi-state Charlotte
Area.\29\

C. EPA's Analyses of Individual Rule Amendments and Adoptions

    This section will provide a rule by rule analysis of the rules
submitted in the SIP revisions. North Carolina's rule 15A NCAC 02D
.0900 addresses VOC; Rule 15A NCAC 02D .1400 addresses NOX;
and Rule 15A NCAC 02D .2600 addresses Source Testing. Below summarizes
the specifics of each rule and EPA's analyses for these rule changes.
a. CTG Rules
1. Rule 15A NCAC 02D .0915, ``Determination of Solvent Metal Cleaning
VOC Emissions''
    On October 5, 2006 (71 FR 58745), as part of the Group II CTG, EPA
updated the portion of the 1977 Solvent Metal Cleaning CTG regarding
the control of VOC emissions from the use of industrial cleaning
solvents. North Carolina originally adopted this rule in 1979, amended
it November 1, 1984, and submitted it to EPA for approval on November
8, 1984. EPA approved it into the federally-approved SIP on December
19, 1986, (51 FR 45468). The state rule was amended numerous times
after that. Rule 15A NCAC 02D .0915 was referenced in the appendix of
the June 15, 2007, SIP revision but no rule change was made at that
time.
    On June 1, 2008, North Carolina repealed this rule, and replaced it
with existing Rule 15A NCAC 02D .0930, ``Solvent Metal Cleaning;'' and
requirements found in Rule 15A NCAC 02D .2613. In a SIP revision on
November 19, 2008, North Carolina submitted this repeal to EPA for
approval. Today, EPA is taking action to propose approval of the June
15, 2007, SIP revision as it relates to RACT, and to approve the repeal
of Rule 15A NCAC 02D .0915, as submitted in North Carolina's November
19, 2008, SIP revision. EPA is also proposing to approve submittals
that include Rules 15A NCAC 02D .0930, and .2613. Below provides more
details regarding EPA's proposed approval of Rules 15A NCAC 02D .0930,
and .2613.
2. Rule 15A NCAC 02D .0916, ``Determination: VOC Emissions From Bulk
Gasoline Terminals''
    In 1977, EPA established a CTG addressing the control of VOC
emissions from bulk gasoline plants. North Carolina originally adopted
this rule in 1979, amended it November 1, 1984, and submitted it to EPA
for approval on November 8, 1984. EPA approved it into the federally-
approved SIP on December 19, 1986, (51 FR 45468). The state rule was
amended numerous times after that. Rule 15A NCAC 02D .0916 was
referenced in the appendix of the June

15, 2007, SIP revision but no rule change was made at that time.
    On June 1, 2008, North Carolina repealed this rule and replaced it
with Rule 15A NCAC 02D .0927, ``Solvent Metal Cleaning;'' and
requirements found in Rule 15A NCAC 02D .2613. In a SIP revision on
November 19, 2008, North Carolina submitted this repeal to EPA for
approval. Today, EPA is taking action to propose approval of the June
15, 2007, SIP revision as it relates to RACT, and to approve the repeal
of Rule 15A NCAC 02D .0916, as submitted in North Carolina's November
19, 2008, SIP revision. EPA is also proposing to approve Rules 15A NCAC
02D .0927, and .2613. Below provides more details regarding EPA's
proposed approval of Rules 15A NCAC 02D .0927, and .2613.
3. Rule 15A NCAC 02D .0917, ``Automobile and Light Duty Truck
Manufacturing''
    In May 1977, EPA issued a CTG document (1977 CTG) for controlling
VOC emissions from surface coating of automobiles and light-duty
trucks. On October 7, 2008 (73 FR 58481), EPA updated the 1977 CTG, as
part of Group IV CTG, addressing the control of VOC emissions from
automobile and light-duty truck manufacturing.
    North Carolina originally adopted this rule in 1979, amended it a
number of times and submitted it to EPA for approval on April 17, 1990.
EPA approved it into the federally-approved SIP on July 21, 1994, (59
FR 37162). The rule was amended numerous times after that and submitted
to EPA for SIP approval on July 1, 1996. EPA approved these amendments
into the federally-approved SIP on August 1, 1997, (62 FR 41277). Rule
15A NCAC 02D .0917 was referenced in the appendix of the June 15, 2007,
SIP revision but no rule change was made at that time.
    On September 1, 2010, North Carolina repealed this rule and
replaced it with Rule 15A NCAC 02D .0968, ``Automobile and Light Duty
Truck Assembly Coatings.'' In a SIP revision on November 9, 2010, North
Carolina submitted this repeal to EPA for approval. Today, EPA is
taking action to propose approval of the June 15, 2007, SIP revision as
it relates to RACT, and to approve the repeal of Rule 15A NCAC 02D
.0917, as submitted in North Carolina's November 9, 2010, SIP revision.
EPA is also proposing to approve Rule .0968. A detailed rationale is
provided below regarding EPA's proposed approval of Rule .0968.
4. Rule 15A NCAC 02D .0920, ``Paper Coatings''
    In May 1977, EPA established a CTG addressing the control of VOC
emissions from paper coating operations. On October 9, 2007 (73 FR
57215), EPA updated the 1977 CTG, as part of Group III CTG, addressing
the control of VOC emissions from paper, film and foil coating
operations. North Carolina originally adopted this rule in 1979,
amended it a number of times and submitted it to EPA for approval on
April 17, 1990. EPA approved it into the federally-approved SIP on July
21, 1994, (59 FR 37162). The rule was amended again and submitted to
EPA for SIP approval on August 16, 1996. EPA approved these amendments
into the federally-approved SIP on August 1, 1997, (62 FR 41277). Rule
.0920 was referenced in the appendix of the June 15, 2007, SIP revision
but no rule change was made at that time.
    On September 1, 2010, North Carolina repealed this rule and
replaced it with Rule 15A NCAC 02D .0966, ``Paper Film and Foil
Coatings.'' In a SIP revision on November 9, 2010, North Carolina
submitted this repeal to EPA for approval. Today, EPA is taking action
to propose approval of the June 15, 2007, SIP revision as it relates to
RACT, and to approve the repeal of Rule .0920, as submitted in North
Carolina's November 9, 2010, SIP revision. EPA is also proposing to
approve Rule .0966. A detailed rationale is provided below regarding
EPA's proposed approval of Rule .0966.
5. Rule 15A NCAC 02D .0921, ``Fabric and Vinyl Coating''
    In May 1977, EPA established a CTG addressing the control of VOC
emissions from fabric and vinyl coating operations. North Carolina
originally adopted this rule in 1979, amended it a couple of times and
submitted it to EPA for approval on April 17, 1990. EPA approved it
into the federally-approved SIP on July 21, 1994, (59 FR 37162). The
rule was amended again and submitted to EPA for SIP approval on August
16, 1996. EPA approved these amendments into the federally-approved SIP
on August 1, 1997, (62 FR 41277). Rule .0921 was referenced in the
appendix of the June 15, 2007, SIP revision but no rule change was made

Printing.'' In a SIP revision on November 9, 2010, North Carolina
submitted this repeal to EPA for approval. Today, EPA is taking action
to propose approval of the June 15, 2007, SIP revision as it relates to
RACT, and to approve the repeal of Rule .0921, as submitted in North
Carolina's November 9, 2010, SIP revision. EPA is also proposing to
approve Rule .0965. A detailed rationale is provided below regarding
EPA's proposed approval of Rule .0965.
6. Rule 15A NCAC 02D .0922, ``Metal Furniture Coating''
    In June 1978, EPA established a CTG addressing the control of VOC
emissions from Metal Furniture Coating. On October 9, 2007 (73 FR
57215), EPA updated the 1978 CTG, as part of Group III CTG, addressing
control of VOC emissions from metal furniture coating operations. North
Carolina originally adopted this rule in 1979, amended it a couple of
times and submitted it to EPA for approval on April 17, 1990. EPA
approved it into the federally-approved SIP on July 21, 1994, (59 FR
37162). The rule was amended again and submitted to EPA for SIP
approval on August 16, 1996. EPA approved these amendments into the
federally-approved SIP on August 1, 1997, (62 FR 41277). Rule .0922 was
referenced in the appendix of the June 15, 2007, SIP revision but no
rule change was made at that time.
    Changes to this rule were state-effective September 1, 2010, and
submitted in a SIP revision on November 9, 2010, for EPA approval. The
rule was amended to control VOC emissions from metal furniture coatings
by establishing three alternatives. EPA has evaluated North Carolina's
changes and is proposing to approve into the SIP the June 15, 2007, SIP
revision as it relates to RACT, and North Carolina's November 9, 2010,
SIP revision as it relates to metal furniture coating.
7. Rule 15A NCAC 02D .0923, ``Surface Coating of Large Appliance
Parts''
    In May 1977, EPA established a CTG addressing the control of VOC
emissions from large appliance surface coating operations. On October
9, 2007 (73 FR 57215), EPA updated the 1977 CTG, as part of Group III
CTG, addressing the control of VOC emissions from large appliance
surface coating operations. North Carolina originally adopted this rule
in 1979, amended it a couple of times and submitted it to EPA for
approval on April 17, 1990. EPA approved it into the federally-approved
SIP on July 21, 1994, (59 FR 37162). The rule was amended again and
submitted to EPA for SIP approval on August 16, 1996. EPA approved
these amendments into the federally-approved SIP on August 1, 1997, (62
FR 41277). Rule .0923 was referenced in the appendix of

the June 15, 2007, SIP revision but no rule change was made at that
time.
    Changes to this rule were state-effective September 1, 2010, and
submitted in a SIP revision on November 9, 2010, for EPA approval. The
rule was amended to control VOC emissions from large appliance coatings
by establishing three alternatives. EPA has evaluated North Carolina's
changes and is proposing to approve into the SIP the June 15, 2007, SIP
revision as it relates to RACT, and North Carolina's November 9, 2010,
SIP revision as it relates to large appliance coatings.
8. Rule 15A NCAC 02D .0929, ``Petroleum Refinery Sources''
    In 1978, EPA established a CTG addressing the control of VOC
emissions from bulk gasoline plants. North Carolina originally adopted
this rule in 1979, amended it a couple of times and submitted it to EPA
for approval on April 29, 1991. EPA approved it into the federally-
approved SIP on June 23, 1994, (59 FR 32362).
    Rule .0929 was referenced in the appendix of the June 15, 2007, SIP
revision but no rule change was made at that time. In an April 6, 2010,
SIP revision, North Carolina made a negative declaration for this CTG
source category stating that there are no applicable sources in the
North Carolina portion of the bi-state Charlotte Area. As part of its
analysis to support the negative declarations for aforementioned CTG
source categories, NC DENR reviewed its permits files and emissions
inventory information. After this review, NC DENR determined that there
are no stationary sources or emitting facilities located in its portion
of the bi-state Charlotte Area that are subject to aforementioned CTG
source categories. EPA is now proposing to approve the negative
declaration as provided in North Carolina's April 6, 2010, SIP
revision. Today, EPA is also proposing to approve the June 15, 2007,
SIP revision as it relates to the RACT requirements.
9. Rule 15A NCAC 02D .0930, ``Solvent Metal Cleaning''
    On October 5, 2006 (71 FR 58745), as part of the Group II CTG, EPA
updated the portion of the 1977 Solvent Metal Cleaning CTG regarding
the control of VOC emissions from the use of industrial cleaning
solvents. North Carolina originally adopted Rule 15A NCAC 02D .0915,
``Determination of Solvent Metal Cleaning VOC Emissions'' and Rule
.0930, ``Solvent Metal Cleaning'' in 1979. Rule .0915 was amended and
submitted to EPA for approval on April 29, 1991. EPA approved the rule
change on June 23, 1994, (59 FR 32362). Rule 0930, was amended and
submitted to EPA for approval on April 17, 1990. EPA approved the rule
change on June 23, 1994, (59 FR 32362).
    On June 1, 2008, North Carolina repealed Rule .0915,
``Determination of Solvent Metal Cleaning VOC Emissions'' and replaced
it with Rule .0930, ``Solvent Metal Cleaning'' and rules in section
Rule 15A NCAC 02D .2600. In a SIP revision on November 19, 2008, North
Carolina submitted this repeal to EPA for approval. Today, EPA is
taking action to propose approval of the June 15, 2007, SIP revision as
it relates to RACT (Rule .0930, Solvent Metal Cleaning was referenced
in the appendix of the June 15, 2007, SIP revision but no rule change
was made at that time), and to approve the repeal of Rule .0915.
10. Rule 15A NCAC 02D .0932, ``Gasoline Truck Tanks and Vapor
Collection System''
    In 1978 EPA established a CTG addressing VOC emissions from Control
of Volatile Organic Compound Leaks from Gasoline Tank Trucks and Vapor
Collection Systems. North Carolina originally adopted this Rule .0932
in 1980. The following shows the state submittals and corresponding EPA
approvals:
