SUPPLEMENTARY INFORMATION: On June
18, 2020, the Maryland Department of
the Environment (MDE) submitted the
negative declaration for the 2016 Oil
and Gas CTG as a revision to the
Maryland SIP.
I. Background
The CAA regulates emissions of
nitrogen oxides (NOX) and volatile
organic compounds (VOCs) to prevent
photochemical reactions that result in
ozone formation. Reasonably available
control technology (RACT) is a strategy
for reducing NOX and VOC emissions
from stationary sources within areas not
meeting the National Ambient Air
Quality Standards (NAAQS) for ozone.
EPA has consistently defined ‘‘RACT’’
as the lowest emission limit that a
particular source is capable of meeting
by the application of the control
technology that is reasonably available
considering technological and economic
feasibility.
Control Technique Guidelines (CTGs)
and Alternative Control Techniques
(ACTs) form important components of
the guidance that EPA provides to states
for making RACT determinations. CTGs
are used to presumptively define VOC
RACT for applicable source categories.
CAA section 182(b)(2)(A) requires that
for ozone nonattainment areas classified
as moderate or above, states must revise
their SIPs to include provisions to
implement RACT for each category of
VOC sources covered by a CTG
document. CAA section 184(b)(1)(B)
extends the RACT obligation to all areas
of states within the Ozone Transport
Region (OTR), including Maryland.1
States subject to RACT requirements
are required to enact controls for
sources subject to CTGs that are at least
as stringent as those found within the
CTG either via the adoption of
regulations, or by issuance of single
source permits that outline what the
source is required to do to meet RACT.2
On March 6, 2016 (80 FR 12264), EPA
issued a final rule entitled
‘‘Implementation of the 2008 National
1 CAA section 184(a) establishes a single OTR
comprised of 11 eastern states (including Maryland)
and the Consolidated Metropolitan Statistical Area
(CMSA) that includes the District of Columbia.
2 EPA took final action to approve Maryland’s SIP
revision addressing VOC RACT requirements
(including the other CTGs) for the 2008 8-hour
ozone NAAQS on February 20, 2019. See 84 FR
5004.

Frm 00022
Fmt 4702
Sfmt 4702
Ambient Air Quality Standards for
Ozone: State Implementation Plan
Requirements’’ (2008 Ozone
Implementation Rule). In the preamble
to the final rule, EPA makes clear that
if there are no sources covered by a
specific CTG source category located in
an ozone nonattainment area or an area
in the OTR, the state may submit a
negative declaration for that CTG. See
80 FR 12264, 12278.
On October 27, 2016 (81 FR 74798),
EPA published in the Federal Register
the ‘‘Release of Final Control
Techniques Guidelines for the Oil and
Natural Gas Industry,’’ (2016 Oil and
Gas CTG).3 This CTG provided
information to state, local, and tribal air
agencies to assist in determining RACT
for VOC emissions from certain VOC
emission source within the oil and
natural gas industry. The 2016 Oil and
Gas CTG replaces an earlier 1983 CTG
entitled ‘‘Control of Volatile Organic
Compound Equipment Leaks from
Natural Gas/Gasoline Processing Plants.
December 1983.’’ EPA–450/3–83–007
(1983 CTG) 49 FR 4432; February 6,
1984. See 2016 Oil and Gas CTG, p. 8–
1.
II. Summary of SIP Revision and EPA
Analysis
The 2016 Oil and Gas CTG divides the
industry into four segments: Production,
processing, transmission and storage,
and distribution. The transmission and
storage sector includes compressor
stations, pipelines and storage facilities.
The distribution sector is the final step
in delivering natural gas to customers
and includes gas mains and service
pipelines. See CTG p. 3–1; see also CTG
pp. 3–1 through 3–3 for a brief
explanation of each segment. However,
not all four segments of the industry are
subject to the requirements of the CTG.
The CTG covers select sources of VOC
emissions in the onshore production
and processing segments of the oil and
natural gas industry (i.e., pneumatic
controllers, pneumatic pumps,
compressors, equipment leaks, fugitive
emissions) and storage vessel VOC
emissions in all segments (except
distribution) of the oil and natural gas
industry. These sources were selected
for RACT recommendations because
current information indicates that they
are significant sources of VOC
emissions.
According to Maryland’s June 18,
2020 submittal, MDE conducted a
review of potential sources subject to

Federal Register / Vol. 86, No. 25 / Tuesday, February 9, 2021 / Proposed Rules
the 2016 Oil and Gas CTG. This review
consisted of a search of Maryland’s oil
and gas well records, air permit records,
EPA greenhouse gas reporting records,
and the Standard Industrial
Classification (SIC) system.4 MDE’s
search identified a total of 13 facilities
in Maryland operating in the
production, processing, or transmission
and storage segments of the oil and
natural gas industry. However, none of
these facilities met or exceeded the
applicability criteria of the CTG.5 MDE
identified five facilities in the natural
gas transmission sector, but determined
that none of them had storage tanks
with the potential to emit (PTE) more
than 6 tons per year (tpy) of VOCs,
which is the threshold for applicability
of the CTG. Additionally, MDE
identified eight active individual
production wells. None of these
exceeded the 15 barrel equivalents per
day per well threshold for CTG
applicability. Further, none of the
production wells were determined to
operate pneumatic pumps or
controllers, or compressors. Finally,
with respect to fugitive emissions, none
of the wells exceed the applicability
threshold of a gas to oil ratio (GOR) of
300 or greater.
III. Proposed Action
EPA’s review of this material
indicates that it meets all applicable
CAA requirements, including CAA
sections 182(b)(2)(A) and 184(b)(1)(B),
and that MDE has satisfactorily
demonstrated that there are no sources
operating in Maryland subject to the
2016 Oil and Gas CTG. EPA is
proposing to approve Maryland’s June
18, 2020 negative declaration SIP
submittal as a revision to the Maryland
SIP. EPA is soliciting public comments
on Maryland’s negative declaration,
including the adequacy of MDE’s search
and analysis of the CTG applicability
criteria. Comments concerning the
adequacy of the 2016 Oil and Gas CTG
itself are not germane to this action and
will not be considered. Relevant
comments will be considered before
taking final action.

EPA’s role is to approve state choices,
provided that they meet the criteria of
the CAA. Accordingly, this action
merely approves state law as meeting
Federal requirements and does not
impose additional requirements beyond
those imposed by state law. For that
reason, this proposed action:
• Is not a ‘‘significant regulatory
action’’ subject to review by the Office
of Management and Budget under
Executive Orders 12866 (58 FR 51735,
October 4, 1993) and 13563 (76 FR 3821,
January 21, 2011);
• Is not an Executive Order 13771 (82
FR 9339, February 2, 2017) regulatory
action because this is not a ‘‘significant
regulatory action’’ under Executive
Order 12866.
• Does not impose an information
collection burden under the provisions
of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.);
• Is certified as not having a
significant economic impact on a
substantial number of small entities
under the Regulatory Flexibility Act (5
U.S.C. 601 et seq.);
• Does not contain any unfunded
mandate or significantly or uniquely
affect small governments, as described
in the Unfunded Mandates Reform Act
of 1995 (Pub. L. 104–4);
• Does not have Federalism
implications as specified in Executive
Order 13132 (64 FR 43255, August 10,
1999);
• Is not an economically significant
regulatory action based on health or
safety risks subject to Executive Order
13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action
subject to Executive Order 13211 (66 FR
28355, May 22, 2001);
• Is not subject to requirements of
section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) because
application of those requirements would
be inconsistent with the CAA; and
• Does not provide EPA with the
discretionary authority to address, as
appropriate, disproportionate human
health or environmental effects, using
practicable and legally permissible
methods, under Executive Order 12898
(59 FR 7629, February 16, 1994).
In addition, this proposed
rulemaking, pertaining to Maryland’s
negative declaration for the 2016 Oil
and Gas CTG, does not have tribal
implications as specified by Executive
Order 13175 (65 FR 67249, November 9,
2000), because the SIP is not approved
to apply in Indian country located in the
State, and EPA notes that it will not
impose substantial direct costs on tribal
governments or preempt tribal law.

II. Summary of SIP Revision and EPA Analysis
The 2016 Oil and Gas CTG divides the industry into four segments:
Production, processing, transmission and storage, and distribution. The
transmission and storage sector includes compressor stations, pipelines
and storage facilities. The distribution sector is the final step in
delivering natural gas to customers and includes gas mains and service
pipelines. See CTG p. 3-1; see also CTG pp. 3-1 through 3-3 for a brief
explanation of each segment. However, not all four segments of the
industry are subject to the requirements of the CTG. The CTG covers
select sources of VOC emissions in the onshore production and
processing segments of the oil and natural gas industry (i.e.,
pneumatic controllers, pneumatic pumps, compressors, equipment leaks,
fugitive emissions) and storage vessel VOC emissions in all segments
(except distribution) of the oil and natural gas industry. These
sources were selected for RACT recommendations because current
information indicates that they are significant sources of VOC
emissions.
According to Maryland's June 18, 2020 submittal, MDE conducted a
review of potential sources subject to
