ACTION: Proposed rule.
Through letters dated April 4, 2017,
August 22, 2017, and September 28,
2018, the State of North Carolina,
through NCDEQ, submitted three SIP
VerDate Sep<11>2014

Jkt 247001
revisions for EPA approval.1 These SIP
revisions include structural
amendments to 15A North Carolina
Administrative Code (NCAC) 02D
Section .0501—Compliance with
Emission Control Standards, and
typographical amendments to 15A
NCAC 02D Section .0536—Particulate
Emissions from Electric Utility Boilers.2
Additionally, the SIP revisions
incorporate, for primarily structural,
organizational reasons, four new rules:
15A NCAC 02D Sections .2609—
Particulate Testing Method, .2610—
Opacity, .2611—Sulfur Dioxide Testing
Methods, and .2617—Total Reduced
Sulfur. EPA has preliminarily
determined that a number of these
changes to the North Carolina SIP are
either structural or minor and
ministerial and do not alter the meaning
of any SIP provisions, that others are
SIP-strengthening, and that all are
consistent with federal regulations
regarding source testing and are
approvable pursuant to section 110 of
the CAA. The changes that are the
subject of this proposed rulemaking are
described in further detail in section III
below.
II. Background
On November 19, 2008, North
Carolina submitted to EPA for approval
a SIP revision which restructured the
way the SIP identified source testing
methods. The November 19, 2008, SIP
revision removed all references to
required source testing methods from
the source-category rules of the SIP and
compiled them into a new section:
Subchapter 2D Section .2600, Source
Testing. This new rule section
consolidated North Carolina’s testing
protocols with federal air source testing
methods formerly located throughout
DEQ’s rules and amended existing
source-category standards to add crossreferences to the applicable testing rules
in the new section, 2D Section .2600.
EPA partially approved the November
19, 2008, SIP revision, together with
several other SIP revisions, but did not
act on some of the proposed
amendments at the time. See 78 FR
27065 (May 9, 2013).
Through a letter dated April 4, 2017,
North Carolina submitted a request to
withdraw some of the proposed changes
from the November 19, 2008, SIP
revision and to resubmit these changes

Federal Register / Vol. 84, No. 29 / Tuesday, February 12, 2019 / Proposed Rules
for EPA’s approval. In its request, North
Carolina withdrew amendments to 2D
Sections .0501—Compliance with
Emission Control Standards, .0536—
Particulate Emissions from Electric
Utility Boilers, and .2609—Particulate
Testing Methods, as well as one rule
under Subchapter 2Q, Section .0523—
Changes Not Requiring Permit Revisions
and resubmitted these changes with an
updated redline strikeout of each
section.
Similarly, through a letter dated
August 22, 2017, North Carolina
withdrew from the November 19, 2008,
SIP revision, new provisions found at
2D Sections .2610—Opacity, .2611—
Sulfur Dioxide Testing Methods, and
.2617—Total Reduced Sulfur, and
resubmitted these new provisions with
an updated redline strikeout of each
new section.
Lastly, in letters dated September 28,
2018, North Carolina submitted: (1) An
additional SIP withdrawal and revision,
and (2) a separate withdrawal.
Specifically, the September 28, 2018,
SIP revision withdrew the changes to 2D
Sections .0501 and addition of .2609
from the April 4, 2017, SIP revision, and
concurrently resubmitted these for
incorporation into the SIP with updated
redline strikeouts. In the separate
withdrawal letter, also dated September
28, 2018, North Carolina withdrew 2Q
Section .0523 from the April 4, 2017,
SIP revision.3 North Carolina decided
not to resubmit 2Q Section .0523
because this provision applies to North
Carolina’s Title V permitting program
and is not appropriate for approval into
the SIP.
The changes proposed for approval
herein are a part of North Carolina’s
strategy to attain and maintain the
national ambient air quality standards
(NAAQS), and EPA has preliminarily
determined that they are approvable
pursuant to section 110 of the CAA. The
changes that are the subject of this
proposed rulemaking and EPA’s
rationale for proposing to approve them
are described in further detail below.
III. Analysis of the State Submittal
EPA is proposing to approve into the
North Carolina SIP amendments to
Subchapter 2D Sections .0501—
Compliance with Emission Control
Standards, and .0536—Particulate
Emissions from Electric Utility Boilers,
as well as the addition of four new
rules, Sections .2609—Particulate

Jkt 247001
and .2617—Total Reduced Sulfur.
Below is a description of these changes
and our rationale for proposing to
approve them.
A. Section .0501—Compliance With
Emission Control Standards
Section .0501 is amended by
removing all language regarding testing
methods for determining compliance
with emission control standards, which
was previously found in paragraphs (b)
and (c)(1) through (c)(18). As mentioned
in Section II, above, North Carolina’s
November 19, 2008, SIP revision
included a new set of rules at 2D
Section .2600, Source Testing. As
described in more detail below, the
operative portions of the deleted
language from Section .0501 have all
been relocated to the appropriate
subsections of 2D Section .2600, some of
which were previously approved into
the SIP in 2013. See 78 FR 27065 (May
9, 2013). Other subsections of 2D
Section .2600 are now being proposed
for SIP approval through the April 4,
2017, August 22, 2017, and September
28, 2018, SIP revisions. In addition, all
of the corresponding deletions of
Section .0501 language are now being
proposed for SIP approval. Further
details on the proposed deletions of the
Section .0501 testing methods and their
current or new locations are presented
below.
1. Whereas the relocation of Section
.0501’s testing methods to Section .2600
was previously approved in the 2013
final rule for the November 19, 2008,
SIP revision, the corresponding deletion
of the paragraphs from Section .0501
now being proposed for approval is as
follows 4:
• Paragraphs (b), (c)(14), and (c)(18)
language is found in current Section
.2602—General Provisions on Test
Methods and Procedures.
• Paragraph (c)(1) language is found
in current Section .2604—Number of
Test Points.
• Paragraph (c)(2) language is found
in current Section .2605—Velocity and
Volume Flow Rate.
• Paragraph (c)(7) language is found
in current Section .2612—Nitrogen
Oxide Testing Methods.
• Paragraph (c)(12) language is found
in current Section .2608—Number of
Runs and Compliance Determination.
4 Paragraph (c)(9) language is found in Section
.2616—Fluorides, and paragraph (c)(11) language is
found in Section .2618—Mercury, but these
Sections are currently not part of the North Carolina
SIP. Sections .2616 and .2618 have not been
incorporated into the SIP because North Carolina
withdrew its request to adopt them into its SIP on
September 1, 2016, letter. These rules pertain to
CAA section 111(d) or 129 plans and not CAA
section 110.
PO 00000
Frm 00039
Fmt 4702

• Paragraph (c)(13) language is found
in current Section .2606—Molecular
Weight.
• Paragraph (c)(15) language is found
in current Section .2621—Determination
of Fuel Heat Content Using F-Factor.
• Paragraph (c)(17) language is found
in current Section .2613—Volatile
Organic Compound Testing Methods.
2. Deletion being proposed for
approval through the April 4, 2017, SIP
revisions:
• Paragraph (c)(3) and (c)(16)
language is found in new Section
.2609—Particulate Testing Methods.
3. Deletion being proposed for
approval through the August 22, 2017,
SIP revision:
• Paragraph (c)(4), (c)(5), and (c)(6)
language is found in new Section
.2611—Sulfur Dioxide Testing Methods.
• Paragraph (c)(8) language is found
in new Section .2610—Opacity.
• Paragraph (c)(10) language is found
in new Section .2617—Total Reduced
Sulfur.
If EPA finalizes this proposed
approval, all of the necessary testing
methods will have been deleted from
Section .0501 and relocated to one of
the current or new subsections in
Section .2600. EPA has reviewed these
changes to Section .0501 and has
preliminarily determined that they are
approvable pursuant to section 110 of
the CAA because they are structural in
nature and the deleted language is
relocated and retained in 2D Section
.2600 of the North Carolina SIP.
B. Section .0536—Particulate Emissions
From Electric Utility Boilers
Section .0536 is amended by updating
cross-references that identify the
location of the testing method
procedures and requirements.
Previously, Section .0536 referred to
Section .0501 to identify the applicable
procedures and requirements for stack
testing when measuring emission rates
for electric utility boilers. Because North
Carolina has relocated all language
regarding testing methods to Section
.2600, amendments to Section .0536
substitute all cross-references to Section
.0501 with cross-references to Section
.2600.
Additionally, North Carolina is
adding a reference in Section .0536 to
its quality assurance program found in
Section .0613 and making a minor
typographical change by substituting the
word ‘‘director’’ with ‘‘Director’’
throughout Section .0536.
EPA has reviewed these changes and
has preliminarily determined that the
amendments to Section .0536 are minor
ministerial changes that do not result in
a change to the existing source testing

Federal Register / Vol. 84, No. 29 / Tuesday, February 12, 2019 / Proposed Rules
requirements in the North Carolina SIP
and are approvable pursuant to section
110 of the Act.
C. Section .2609—Particulate Testing
Methods
As noted in Section III.A.2, above,
most of the language of new Section
.2609 was previously found in
paragraphs (c)(3) and (c)(16) of Section
.0501, which are now being proposed
for deletion. Section .2609 adopts the
federal testing Method 5 of Appendix A
of 40 CFR part 60, and Method 202 of
Appendix M of 40 CFR part 51, which
are meant to demonstrate compliance
with particulate matter (PM) emission
standards. As an alternative to Method
5, Section .2609 also adopts Method 17
of Appendix A of 40 CFR part 60, which
can be used under certain testing
conditions. For steam generators that
use soot blowing as a routine method of
cleaning heat transfer surfaces, Section
.2609 also establishes specific testing
requirements to account for the soot’s
contribution to particulate emissions.
Lastly, paragraph (f) of Section .2609
establishes requirements for sources to
use Method 201 or 201A, in
combination with Method 202, to
demonstrate compliance specifically for
PM10 emission standards.
Method 5 and Method 17, which are
meant to measure filterable PM, were
testing method options previously
found in Section .0501 that are now
relocated to new Section .2609. A
source’s total particulate emissions,
however, also includes condensable PM,
and is measured using different testing
methods. The additional requirement in
.2609 to use Method 202 to demonstrate
compliance with particulate emission
standards, as well as the option to use
a combination of Methods 201 or 201A
in conjunction with Method 202 for
PM10 compliance, are new provisions to
this rule that require testing of
condensable PM as well as filterable
PM. North Carolina requires the use of
testing methods for both filterable and
condensable PM to capture total
particulate emissions.
EPA has reviewed this change and has
preliminarily determined that the
addition of Section .2609, including the
additional test methods, is consistent
with federal regulations. The addition of
new Section .2609 both retains and
strengthens the existing source testing
requirements of the North Carolina SIP.
D. Section .2610—Opacity
As noted in Section III.A.3, above,
most of the language of new Section
.2610 was previously found in
paragraph (c)(8) of Section .0501, which
is being proposed for deletion. Section
VerDate Sep<11>2014
18:15 Feb 11, 2019
Jkt 247001
.2610 adopts the federal Method 9 of
Appendix A of 40 CFR part 60, which
is meant to determine compliance with
opacity standards by visual observation,
and Method 22 of Appendix A of 40
CFR part 60, which is meant to
determine compliance with opacity
standards when they are based upon the
frequency of fugitive emissions from
stationary sources as specified in an
applicable rule.
The requirement to use Method 9
when determining opacity by visual
observation was previously found in
Section .0501 and is now relocated to
new Section .2610. A new provision not
found in Section .0501 is the option to
use Method 22 for determining
compliance with opacity standards
based upon the frequency of fugitive
emissions from stationary sources. The
use of Method 22, as described in
Section .2609, is allowed only in cases
where this method is required by a
permit condition or another applicable
regulation.
EPA has reviewed this change and has
preliminarily determined that the
addition of new Section .2610,
including the option to use Method 22,
is consistent with federal regulations.
The addition of new Section .2610 both
retains and strengthens the existing
source testing requirements of the North
Carolina SIP.
E. Section .2611—Sulfur Dioxide
Testing Methods
As noted in Section III.A.3, above, the
language of this new provision, Section
.2611, was previously found in
paragraphs (c)(4), (5), and (6) of Section
.0501, which are being proposed for
deletion. Section .2611 establishes
testing methods and methodologies for
sulfur dioxide in different types of
sources, specifically:
a. If compliance is to be demonstrated
for a combustion source through stack
sampling, the procedures described in
Method 6 or Method 6C of Appendix A
of 40 CFR part 60 shall be used. When
using Method 6 procedures to
demonstrate compliance, compliance
shall be determined by averaging six 20minute samples taken over such a
period of time that no more than 20
minutes elapses between any two
consecutive samples. The 20-minute run
requirement applies to Method 6 only,
not to Method 6C. Method 6C is an
instrumental method and the sampling
is done continuously.
b. Fuel burning sources not required
to use continuous emissions monitoring
to demonstrate compliance with sulfur
dioxide emission standards may
determine compliance with sulfur
dioxide emission standards by stack
PO 00000
Frm 00040
Fmt 4702
Sfmt 4702
3383
sampling or by analyzing the sulfur
content of the fuel.
c. For stationary gas turbines, Method
20 of 40 CFR part 60 shall be used to
demonstrate compliance with
applicable sulfur dioxide emissions
standards.
d. When compliance is to be
demonstrated for a combustion source
by analysis of sulfur in fuel, sampling,
preparation, and analysis of fuels shall
be according to American Society of
Testing and Materials (ASTM) methods.
The Director may approve ASTM
methods different from those described
in the regulation if they will provide
equivalent or more reliable results. The
Director may prescribe alternate ASTM
methods on an individual basis if that
action is necessary to secure reliable test
data. Paragraph (d)(1) of Section .2611
outlines specific ASTM methods for
Coal Sampling, and paragraph (d)(2)
outlines specific ASTM methods for Oil
Sampling.
e. When compliance is shown for
sulfuric acid manufacturing plants or
spodumene ore roasting plants through
stack sampling using the methods
provided in Sections .0517 and .0527,
respectively, the procedures described
in Method 8 of Appendix A of 40 CFR
part 60 shall be used. When Method 8
of Appendix A of 40 CFR part 60 is used
to determine compliance, compliance
shall be determined by averaging
emissions measured by three one-hour
test runs unless otherwise specified in
the applicable rule or subpart of 40 CFR
part 60.
f. When compliance is shown for a
combustion source emitting sulfur
dioxide not covered under paragraphs
(a) through (e) of Section .2611 through
stack sampling, the procedures
described in Method 6 or Method 6C of
Appendix A of 40 CFR part 60 shall be
used. When using Method 6 procedures
to demonstrate compliance, compliance
shall be determined by averaging six 20minute samples taken over such a
period of time that no more than 20
minutes elapses between any two
consecutive samples. The 20-minute run
requirement applies to Method 6 only,
not to Method 6C. Method 6C is an
instrumental method and the sampling
is done continuously.
All of the above the testing methods
identified in Section .2611 were
previously found in Section .0501, with
the exception of Method 6C. This new
alternative method allows for the use of
a sampling instrument that tests
continuously rather than periodically.
EPA has reviewed this change and has
preliminarily determined that the
addition of new Section .2611,
including the addition of Method 6C as
E:\FR\FM\12FEP1.SGM
12FEP1
3384
Federal Register / Vol. 84, No. 29 / Tuesday, February 12, 2019 / Proposed Rules
an alternative method, is consistent
with federal regulations. The addition of
new Section .2611 both retains and
strengthens the existing source testing
requirements of the North Carolina SIP.
F. Section .2617—Total Reduced Sulfur
As noted in Section III.A.3, above, the
language of this new provision, Section
.2617, was previously found in
paragraph (c)(10) of Section .0501,
which is being proposed for deletion.
Section .2617 adopts the use of federal
testing Method 16 of Appendix A of 40
CFR part 60 or Method 16A of
Appendix A of 40 CFR part 60 to
demonstrate compliance with total
reduced sulfur emissions standards. The
rule also adopts the federal testing
Method 15 of Appendix A of 40 CFR
part 60 to be used as an alternative to
determine total reduced sulfur
emissions from tail gas control units of
sulfur recovery plants, hydrogen sulfide
in fuel gas for fuel gas combustion
devices, and where specified in other
applicable subparts of 40 CFR part 60.
The requirement to use Method 16 or
16A was previously found in Section
.0501 and is now relocated to new
Section .2617. The option to use Method
15 in certain circumstances is a new
provision to this rule. Although Method
15 has a slightly different process of
testing for reduced sulfur, the resulting
conclusions are the same. Additionally,
consistent with section 1.2.1 of Method
15 in the CFR, Section .2617 provides
that Method 15 may be used only as an
alternative in certain specified sources,
as described in the paragraph above, or
where specified in other applicable
federal subparts.
EPA has reviewed this change and has
preliminarily determined that the
addition of Section .2617, including the
addition of Method 15 for certain
sources, is consistent with federal
regulations. EPA is proposing to
approve all changes in this section of
this rulemaking pursuant to section 110
of the Act.
IV. Incorporation by Reference
In this rule, EPA is proposing to
include in a final EPA rule, regulatory
text that includes incorporation by
reference. In accordance with
requirements of 1 CFR 51.5, EPA is
proposing to incorporate by reference
under Subchapter 2D, of the North
Carolina SIP, Sections .0501—
Compliance with Emission Control
Standards, .0536—Particulate
Emissions from Electric Utility Boilers,
.2609—Particulate Testing Methods,
.2610—Opacity, .2611—Sulfur Dioxide

2008. EPA has made, and will continue
to make, these materials generally
available through www.regulations.gov
and at the EPA Region 4 office (please
contact the person identified in the FOR
FURTHER INFORMATION CONTACT section of
this preamble for more information).
V. Proposed Actions
EPA is proposing to approve North
Carolina’s April 4, 2017, August 22,
2017, and September 28, 2018, SIP
revisions. Specifically, EPA is proposing
to approve under Subchapter 2D of the
North Carolina SIP, the adoption of new
Sections .2609, .2610, .2611, and .2617,
as well as amendments to existing
Sections .0501 and .0536. EPA is
proposing to approve these revisions
under section 110 of the CAA, including
section 110(l), for the reasons stated
above.5
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.
See 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. These actions merely propose
to approve state law as meeting Federal
requirements and do not impose
additional requirements beyond those
imposed by state law. For that reason,
these proposed actions:
• Are not significant regulatory
actions subject to review by the Office
of Management and Budget under
Executive Orders 12866 (58 FR 51735,
October 4, 1993) and 13563 (76 FR 3821,
January 21, 2011);
• Are not Executive Order 13771 (82
FR 9339, February 2, 2017) regulatory
actions because SIP approvals are
exempted under Executive Order 12866;
• Do not impose an information
collection burden under the provisions
of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.);
• Are 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.);
• Do not contain any unfunded
mandate or significantly or uniquely

SUPPLEMENTARY INFORMATION:
I. What action is the EPA taking today?
Through letters dated April 4, 2017, August 22, 2017, and September
28, 2018, the State of North Carolina, through NCDEQ, submitted three
SIP revisions for EPA approval.\1\ These SIP revisions include
structural amendments to 15A North Carolina Administrative Code (NCAC)
02D Section .0501--Compliance with Emission Control Standards, and
typographical amendments to 15A NCAC 02D Section .0536--Particulate
Emissions from Electric Utility Boilers.\2\ Additionally, the SIP
revisions incorporate, for primarily structural, organizational
reasons, four new rules: 15A NCAC 02D Sections .2609--Particulate
Testing Method, .2610--Opacity, .2611--Sulfur Dioxide Testing Methods,
and .2617--Total Reduced Sulfur. EPA has preliminarily determined that
a number of these changes to the North Carolina SIP are either
structural or minor and ministerial and do not alter the meaning of any
SIP provisions, that others are SIP-strengthening, and that all are
consistent with federal regulations regarding source testing and are
approvable pursuant to section 110 of the CAA. The changes that are the
subject of this proposed rulemaking are described in further detail in
section III below.
---------------------------------------------------------------------------
\1\ EPA received the SIP revisions on April 28, 2017, September
6, 2017, and October 10, 2018, respectively.
\2\ In the table of North Carolina regulations federally
approved into the SIP at 40 CFR 52.1770(c), 15A NCAC 02D is referred
to as ``Subchapter 2D Air Pollution Control Requirements.''
---------------------------------------------------------------------------
II. Background
On November 19, 2008, North Carolina submitted to EPA for approval
a SIP revision which restructured the way the SIP identified source
testing methods. The November 19, 2008, SIP revision removed all
references to required source testing methods from the source-category
rules of the SIP and compiled them into a new section: Subchapter 2D
Section .2600, Source Testing. This new rule section consolidated North
Carolina's testing protocols with federal air source testing methods
formerly located throughout DEQ's rules and amended existing source-
category standards to add cross-references to the applicable testing
rules in the new section, 2D Section .2600. EPA partially approved the
November 19, 2008, SIP revision, together with several other SIP
revisions, but did not act on some of the proposed amendments at the
time. See 78 FR 27065 (May 9, 2013).
Through a letter dated April 4, 2017, North Carolina submitted a
request to withdraw some of the proposed changes from the November 19,
2008, SIP revision and to resubmit these changes
[[Page 3382]]
for EPA's approval. In its request, North Carolina withdrew amendments
to 2D Sections .0501--Compliance with Emission Control Standards,
.0536--Particulate Emissions from Electric Utility Boilers, and .2609--
Particulate Testing Methods, as well as one rule under Subchapter 2Q,
Section .0523--Changes Not Requiring Permit Revisions and resubmitted
these changes with an updated redline strikeout of each section.
Similarly, through a letter dated August 22, 2017, North Carolina
withdrew from the November 19, 2008, SIP revision, new provisions found
at 2D Sections .2610--Opacity, .2611--Sulfur Dioxide Testing Methods,
and .2617--Total Reduced Sulfur, and resubmitted these new provisions
with an updated redline strikeout of each new section.
Lastly, in letters dated September 28, 2018, North Carolina
submitted: (1) An additional SIP withdrawal and revision, and (2) a
separate withdrawal. Specifically, the September 28, 2018, SIP revision
withdrew the changes to 2D Sections .0501 and addition of .2609 from
the April 4, 2017, SIP revision, and concurrently resubmitted these for
incorporation into the SIP with updated redline strikeouts. In the
separate withdrawal letter, also dated September 28, 2018, North
Carolina withdrew 2Q Section .0523 from the April 4, 2017, SIP
revision.\3\ North Carolina decided not to resubmit 2Q Section .0523
because this provision applies to North Carolina's Title V permitting
program and is not appropriate for approval into the SIP.
---------------------------------------------------------------------------
\3\ The September 28, 2018, withdrawal letter can be found in
the docket for this proposed rulemaking.
---------------------------------------------------------------------------
The changes proposed for approval herein are a part of North
Carolina's strategy to attain and maintain the national ambient air
quality standards (NAAQS), and EPA has preliminarily determined that
they are approvable pursuant to section 110 of the CAA. The changes
that are the subject of this proposed rulemaking and EPA's rationale
for proposing to approve them are described in further detail below.
III. Analysis of the State Submittal
EPA is proposing to approve into the North Carolina SIP amendments
to Subchapter 2D Sections .0501--Compliance with Emission Control
Standards, and .0536--Particulate Emissions from Electric Utility
Boilers, as well as the addition of four new rules, Sections .2609--
Particulate Testing Methods, .2610--Opacity, .2611--Sulfur Dioxide
Testing Methods, and .2617--Total Reduced Sulfur. Below is a
description of these changes and our rationale for proposing to approve
them.
A. Section .0501--Compliance With Emission Control Standards
Section .0501 is amended by removing all language regarding testing
methods for determining compliance with emission control standards,
which was previously found in paragraphs (b) and (c)(1) through
(c)(18). As mentioned in Section II, above, North Carolina's November
19, 2008, SIP revision included a new set of rules at 2D Section .2600,
Source Testing. As described in more detail below, the operative
portions of the deleted language from Section .0501 have all been
relocated to the appropriate subsections of 2D Section .2600, some of
which were previously approved into the SIP in 2013. See 78 FR 27065
(May 9, 2013). Other subsections of 2D Section .2600 are now being
proposed for SIP approval through the April 4, 2017, August 22, 2017,
and September 28, 2018, SIP revisions. In addition, all of the
corresponding deletions of Section .0501 language are now being
proposed for SIP approval. Further details on the proposed deletions of
the Section .0501 testing methods and their current or new locations
are presented below.
1. Whereas the relocation of Section .0501's testing methods to
Section .2600 was previously approved in the 2013 final rule for the
November 19, 2008, SIP revision, the corresponding deletion of the
paragraphs from Section .0501 now being proposed for approval is as
follows \4\:
---------------------------------------------------------------------------
\4\ Paragraph (c)(9) language is found in Section .2616--
Fluorides, and paragraph (c)(11) language is found in Section
.2618--Mercury, but these Sections are currently not part of the
North Carolina SIP. Sections .2616 and .2618 have not been
incorporated into the SIP because North Carolina withdrew its
request to adopt them into its SIP on September 1, 2016, letter.
These rules pertain to CAA section 111(d) or 129 plans and not CAA
section 110.
---------------------------------------------------------------------------
Paragraphs (b), (c)(14), and (c)(18) language is found in
current Section .2602--General Provisions on Test Methods and
Procedures.
Paragraph (c)(1) language is found in current Section
.2604--Number of Test Points.
Paragraph (c)(2) language is found in current Section
.2605--Velocity and Volume Flow Rate.
Paragraph (c)(7) language is found in current Section
.2612--Nitrogen Oxide Testing Methods.
Paragraph (c)(12) language is found in current Section
.2608--Number of Runs and Compliance Determination.
Paragraph (c)(13) language is found in current Section
.2606--Molecular Weight.
Paragraph (c)(15) language is found in current Section
.2621--Determination of Fuel Heat Content Using F-Factor.
Paragraph (c)(17) language is found in current Section
.2613--Volatile Organic Compound Testing Methods.
2. Deletion being proposed for approval through the April 4, 2017,
SIP revisions:
Paragraph (c)(3) and (c)(16) language is found in new
Section .2609--Particulate Testing Methods.
3. Deletion being proposed for approval through the August 22,
2017, SIP revision:
Paragraph (c)(4), (c)(5), and (c)(6) language is found in
new Section .2611--Sulfur Dioxide Testing Methods.
Paragraph (c)(8) language is found in new Section .2610--
Opacity.
Paragraph (c)(10) language is found in new Section .2617--
Total Reduced Sulfur.
If EPA finalizes this proposed approval, all of the necessary
testing methods will have been deleted from Section .0501 and relocated
to one of the current or new subsections in Section .2600. EPA has
reviewed these changes to Section .0501 and has preliminarily
determined that they are approvable pursuant to section 110 of the CAA
because they are structural in nature and the deleted language is
relocated and retained in 2D Section .2600 of the North Carolina SIP.
B. Section .0536--Particulate Emissions From Electric Utility Boilers
Section .0536 is amended by updating cross-references that identify
the location of the testing method procedures and requirements.
Previously, Section .0536 referred to Section .0501 to identify the
applicable procedures and requirements for stack testing when measuring
emission rates for electric utility boilers. Because North Carolina has
relocated all language regarding testing methods to Section .2600,
amendments to Section .0536 substitute all cross-references to Section
.0501 with cross-references to Section .2600.
Additionally, North Carolina is adding a reference in Section .0536
to its quality assurance program found in Section .0613 and making a
minor typographical change by substituting the word ``director'' with
``Director'' throughout Section .0536.
EPA has reviewed these changes and has preliminarily determined
that the amendments to Section .0536 are minor ministerial changes that
do not result in a change to the existing source testing
[[Page 3383]]
requirements in the North Carolina SIP and are approvable pursuant to
section 110 of the Act.
C. Section .2609--Particulate Testing Methods
As noted in Section III.A.2, above, most of the language of new
Section .2609 was previously found in paragraphs (c)(3) and (c)(16) of
Section .0501, which are now being proposed for deletion. Section .2609
adopts the federal testing Method 5 of Appendix A of 40 CFR part 60,
and Method 202 of Appendix M of 40 CFR part 51, which are meant to
demonstrate compliance with particulate matter (PM) emission standards.
As an alternative to Method 5, Section .2609 also adopts Method 17 of
Appendix A of 40 CFR part 60, which can be used under certain testing
conditions. For steam generators that use soot blowing as a routine
method of cleaning heat transfer surfaces, Section .2609 also
establishes specific testing requirements to account for the soot's
contribution to particulate emissions. Lastly, paragraph (f) of Section
.2609 establishes requirements for sources to use Method 201 or 201A,
in combination with Method 202, to demonstrate compliance specifically
for PM10 emission standards.
Method 5 and Method 17, which are meant to measure filterable PM,
were testing method options previously found in Section .0501 that are
now relocated to new Section .2609. A source's total particulate
emissions, however, also includes condensable PM, and is measured using
different testing methods. The additional requirement in .2609 to use
Method 202 to demonstrate compliance with particulate emission
standards, as well as the option to use a combination of Methods 201 or
201A in conjunction with Method 202 for PM10 compliance, are
new provisions to this rule that require testing of condensable PM as
well as filterable PM. North Carolina requires the use of testing
methods for both filterable and condensable PM to capture total
particulate emissions.
EPA has reviewed this change and has preliminarily determined that
the addition of Section .2609, including the additional test methods,
is consistent with federal regulations. The addition of new Section
.2609 both retains and strengthens the existing source testing
requirements of the North Carolina SIP.
D. Section .2610--Opacity
As noted in Section III.A.3, above, most of the language of new
Section .2610 was previously found in paragraph (c)(8) of Section
.0501, which is being proposed for deletion. Section .2610 adopts the
federal Method 9 of Appendix A of 40 CFR part 60, which is meant to
determine compliance with opacity standards by visual observation, and
Method 22 of Appendix A of 40 CFR part 60, which is meant to determine
compliance with opacity standards when they are based upon the
frequency of fugitive emissions from stationary sources as specified in
an applicable rule.
The requirement to use Method 9 when determining opacity by visual
observation was previously found in Section .0501 and is now relocated
to new Section .2610. A new provision not found in Section .0501 is the
option to use Method 22 for determining compliance with opacity
standards based upon the frequency of fugitive emissions from
stationary sources. The use of Method 22, as described in Section
.2609, is allowed only in cases where this method is required by a
permit condition or another applicable regulation.
EPA has reviewed this change and has preliminarily determined that
the addition of new Section .2610, including the option to use Method
22, is consistent with federal regulations. The addition of new Section
.2610 both retains and strengthens the existing source testing
requirements of the North Carolina SIP.
E. Section .2611--Sulfur Dioxide Testing Methods
As noted in Section III.A.3, above, the language of this new
provision, Section .2611, was previously found in paragraphs (c)(4),
(5), and (6) of Section .0501, which are being proposed for deletion.
Section .2611 establishes testing methods and methodologies for sulfur
dioxide in different types of sources, specifically:
a. If compliance is to be demonstrated for a combustion source
through stack sampling, the procedures described in Method 6 or Method
6C of Appendix A of 40 CFR part 60 shall be used. When using Method 6
procedures to demonstrate compliance, compliance shall be determined by
averaging six 20-minute samples taken over such a period of time that
no more than 20 minutes elapses between any two consecutive samples.
The 20-minute run requirement applies to Method 6 only, not to Method
6C. Method 6C is an instrumental method and the sampling is done
continuously.
b. Fuel burning sources not required to use continuous emissions
monitoring to demonstrate compliance with sulfur dioxide emission
standards may determine compliance with sulfur dioxide emission
standards by stack sampling or by analyzing the sulfur content of the
fuel.
c. For stationary gas turbines, Method 20 of 40 CFR part 60 shall
be used to demonstrate compliance with applicable sulfur dioxide
emissions standards.
d. When compliance is to be demonstrated for a combustion source by
analysis of sulfur in fuel, sampling, preparation, and analysis of
fuels shall be according to American Society of Testing and Materials
(ASTM) methods. The Director may approve ASTM methods different from
those described in the regulation if they will provide equivalent or
more reliable results. The Director may prescribe alternate ASTM
methods on an individual basis if that action is necessary to secure
reliable test data. Paragraph (d)(1) of Section .2611 outlines specific
ASTM methods for Coal Sampling, and paragraph (d)(2) outlines specific
ASTM methods for Oil Sampling.
e. When compliance is shown for sulfuric acid manufacturing plants
or spodumene ore roasting plants through stack sampling using the
methods provided in Sections .0517 and .0527, respectively, the
procedures described in Method 8 of Appendix A of 40 CFR part 60 shall
be used. When Method 8 of Appendix A of 40 CFR part 60 is used to
determine compliance, compliance shall be determined by averaging
emissions measured by three one-hour test runs unless otherwise
specified in the applicable rule or subpart of 40 CFR part 60.
f. When compliance is shown for a combustion source emitting sulfur
dioxide not covered under paragraphs (a) through (e) of Section .2611
through stack sampling, the procedures described in Method 6 or Method
6C of Appendix A of 40 CFR part 60 shall be used. When using Method 6
procedures to demonstrate compliance, compliance shall be determined by
averaging six 20-minute samples taken over such a period of time that
no more than 20 minutes elapses between any two consecutive samples.
The 20-minute run requirement applies to Method 6 only, not to Method
6C. Method 6C is an instrumental method and the sampling is done
continuously.
All of the above the testing methods identified in Section .2611
were previously found in Section .0501, with the exception of Method
6C. This new alternative method allows for the use of a sampling
instrument that tests continuously rather than periodically.
EPA has reviewed this change and has preliminarily determined that
the addition of new Section .2611, including the addition of Method 6C
as
[[Page 3384]]
an alternative method, is consistent with federal regulations. The
addition of new Section .2611 both retains and strengthens the existing
source testing requirements of the North Carolina SIP.
F. Section .2617--Total Reduced Sulfur
As noted in Section III.A.3, above, the language of this new
provision, Section .2617, was previously found in paragraph (c)(10) of
Section .0501, which is being proposed for deletion. Section .2617
adopts the use of federal testing Method 16 of Appendix A of 40 CFR
part 60 or Method 16A of Appendix A of 40 CFR part 60 to demonstrate
compliance with total reduced sulfur emissions standards. The rule also
adopts the federal testing Method 15 of Appendix A of 40 CFR part 60 to
be used as an alternative to determine total reduced sulfur emissions
from tail gas control units of sulfur recovery plants, hydrogen sulfide
in fuel gas for fuel gas combustion devices, and where specified in
other applicable subparts of 40 CFR part 60.
The requirement to use Method 16 or 16A was previously found in
Section .0501 and is now relocated to new Section .2617. The option to
use Method 15 in certain circumstances is a new provision to this rule.
Although Method 15 has a slightly different process of testing for
reduced sulfur, the resulting conclusions are the same. Additionally,
consistent with section 1.2.1 of Method 15 in the CFR, Section .2617
provides that Method 15 may be used only as an alternative in certain
specified sources, as described in the paragraph above, or where
specified in other applicable federal subparts.
EPA has reviewed this change and has preliminarily determined that
the addition of Section .2617, including the addition of Method 15 for
certain sources, is consistent with federal regulations. EPA is
proposing to approve all changes in this section of this rulemaking
pursuant to section 110 of the Act.
IV. Incorporation by Reference
In this rule, EPA is proposing to include in a final EPA rule,
regulatory text that includes incorporation by reference. In accordance
with requirements of 1 CFR 51.5, EPA is proposing to incorporate by
reference under Subchapter 2D, of the North Carolina SIP, Sections
.0501--Compliance with Emission Control Standards, .0536--Particulate
Emissions from Electric Utility Boilers, .2609--Particulate Testing
Methods, .2610--Opacity, .2611--Sulfur Dioxide Testing Methods, and
.2617--Total Reduced Sulfur, state effective June 1, 2008. EPA has
made, and will continue to make, these materials generally available
through www.regulations.gov and at the EPA Region 4 office (please
contact the person identified in the For Further Information Contact
section of this preamble for more information).
V. Proposed Actions
EPA is proposing to approve North Carolina's April 4, 2017, August
22, 2017, and September 28, 2018, SIP revisions. Specifically, EPA is
proposing to approve under Subchapter 2D of the North Carolina SIP, the
adoption of new Sections .2609, .2610, .2611, and .2617, as well as
amendments to existing Sections .0501 and .0536. EPA is proposing to
approve these revisions under section 110 of the CAA, including section
110(l), for the reasons stated above.\5\
---------------------------------------------------------------------------
\5\ Section 110(l) requires that a revision to the SIP not
interfere with any applicable requirement concerning attainment and
reasonable further progress (as defined in section 171), or any
other applicable requirement of the Act.
---------------------------------------------------------------------------
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. See 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. These actions merely
propose to approve state law as meeting Federal requirements and do not
impose additional requirements beyond those imposed by state law. For
that reason, these proposed actions:
Are not significant regulatory actions subject to review
by the Office of Management and Budget under Executive Orders 12866 (58
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
Are not Executive Order 13771 (82 FR 9339, February 2,
2017) regulatory actions because SIP approvals are exempted under
Executive Order 12866;
Do not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Are 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.);
Do 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);
Do not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Are not economically significant regulatory actions based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Are not significant regulatory actions subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Are 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
Do 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).
The SIP is not approved to apply on any Indian reservation land or
in any other area where EPA or an Indian tribe has demonstrated that a
tribe has jurisdiction. In those areas of Indian country, the rule does
not have tribal implications as specified by Executive Order 13175 (65
FR 67249, November 9, 2000), nor will it impose substantial direct
costs on tribal governments or preempt tribal law.
