VI. Statutory and Executive Order Reviews
I. Background and Purpose
On May 5, 2015, the Massachusetts Department of Environmental
Protection submitted a revision to its State Implementation Plan (SIP).
The SIP revision consists of Massachusetts' revised regulations 310
Code of Massachusetts Regulations (CMR) 7.00, Air Pollution Control:
Definitions and 310 CMR 7.24, Organic Material Storage and
Distribution. Specifically, in addition to the new and revised
definitions in 310 CMR 7.00, the SIP revision consists of
Massachusetts' revised regulation sections:
310 CMR 7.24(3), Distribution of Motor Vehicle Fuel;
310 CMR 7.24(4), Motor Vehicle Fuel Tank Trucks; and
310 CMR 7.24(6), Dispensing of Motor Vehicle Fuel.
These sections of Massachusetts' 310 CMR 7.24 have been revised to
allow the decommissioning of Stage II vapor
[[Page 12441]]
recovery systems and to strengthen Stage I vapor recovery requirements.
The SIP submittal also includes a demonstration that removal of Stage
II vapor recovery systems in Massachusetts is consistent with the Clean
Air Act and EPA guidance.
Stage II and onboard refueling vapor recovery (ORVR) systems are
two types of emission control systems that capture fuel vapors from
vehicle gas tanks during refueling. Stage II vapor recovery systems are
installed at gasoline dispensing facilities (GDFs) and capture the
refueling fuel vapors at the gasoline pump. The system carries the
vapors back to the underground storage tank at the GDF to prevent the
vapors from escaping to the atmosphere. ORVR systems are carbon
canisters installed directly on automobiles to capture the fuel vapors
evacuated from the gasoline tank before they reach the nozzle. The fuel
vapors captured in the carbon canisters are then combusted in the
engine when the automobile is in operation.
Stage II vapor recovery systems and vehicle ORVR systems were
initially both required by the 1990 Amendments to the Clean Air Act
(CAA). Section 182(b)(3) of the CAA requires moderate and above ozone
nonattainment areas to implement Stage II vapor recovery programs.
Also, under CAA section 184(b)(2), states in the Ozone Transport Region
(OTR) are required to implement Stage II or comparable measures. CAA
section 202(a)(6) required EPA to promulgate regulations for ORVR for
light-duty vehicles (passenger cars). EPA adopted these requirements in
1994, at which point moderate ozone nonattainment areas were no longer
subject to the CAA section 182(b)(3) Stage II vapor recovery
requirements. ORVR equipment has been phased in for new passenger
vehicles beginning with model year 1998, and starting with model year
2001 for light-duty trucks and most heavy-duty gasoline powered
vehicles. ORVR equipment has been installed on nearly all new gasoline-
powered light-duty vehicles, light-duty trucks, and heavy-duty vehicles
since 2006.
During the phase-in of ORVR controls, Stage II has provided
volatile organic compound (VOC) reductions in ozone nonattainment areas
and certain attainment areas of the OTR. Congress recognized that ORVR
systems and Stage II vapor recovery systems would eventually become
largely redundant technologies, and provided authority to EPA to allow
states to remove Stage II vapor recovery programs from their SIPs after
EPA finds that ORVR is in ``widespread use.'' Effective May 16, 2012,
the date the final rule was published in the Federal Register (see 77
FR 28772), EPA determined that ORVR systems are in widespread use
nationwide for control of gasoline emissions during refueling of
vehicles at GDFs. Currently, more than 85 percent of gasoline refueling
nationwide occurs with ORVR-equipped vehicles. Thus, Stage II vapor
recovery programs have become largely redundant control systems and
Stage II vapor recovery systems achieve an ever declining emissions
benefit as more ORVR-equipped vehicles continue to enter the on-road
motor vehicle fleet.\1\ In the May 16, 2012 rulemaking, EPA also
exercised its authority under CAA section 202(a)(6) to waive certain
federal statutory requirements for Stage II vapor recovery systems at
GDFs. This decision exempts all new ozone nonattainment areas
classified serious or above from the requirement to adopt Stage II
vapor recovery programs. Finally, EPA's May 16, 2012 rulemaking also
noted that any state currently implementing Stage II vapor recovery
programs may submit SIP revisions that would allow for the phase-out of
Stage II vapor recovery systems.
---------------------------------------------------------------------------
\1\ In areas where certain types of vacuum-assist Stage II vapor
recovery systems are used, the differences in operational design
characteristics between ORVR and some configurations of these Stage
II vapor recovery systems result in the reduction of overall control
system efficiency compared to what could have been achieved relative
to the individual control efficiencies of either ORVR or Stage II
emissions from the vehicle fuel tank.
---------------------------------------------------------------------------
Stage I vapor recovery systems are systems that capture vapors
displaced from storage tanks at GDFs during gasoline tank truck
deliveries. When gasoline is delivered into an aboveground or
underground storage tank, vapors that were taking up space in the
storage tank are displaced by the gasoline entering the storage tank.
The Stage I vapor recovery systems route these displaced vapors into
the delivery truck's tank. Some vapors are vented when the storage tank
exceeds a specified pressure threshold, however the Stage I vapor
recovery systems greatly reduce the possibility of these displaced
vapors being released into the atmosphere.
Stage I vapor recovery systems have been in place since the 1970s.
EPA has issued the following guidance regarding Stage I systems:
``Design Criteria for Stage I Vapor Control Systems--Gasoline Service
Stations'' (November 1975, EPA Online Publication 450R75102), which is
regarded as the control techniques guideline (CTG) for the control of
VOC emissions from this source category; and the EPA document ``Model
Volatile Organic Compound Rules for Reasonably Available Control
Technology'' (Staff Working Draft, June 1992) contains a model Stage I
regulation.
In more recent years, the California Air Resources Board (CARB) has
required Stage I vapor recovery systems capable of achieving vapor
control efficiencies higher than those achieved by traditional systems.
These systems are commonly referred to as Enhanced Vapor Recovery (EVR)
systems.
II. Summary of Massachusetts' SIP Revision
The Massachusetts Stage II vapor recovery program requirements,
codified in 310 Code of Massachusetts Regulations (CMR) 7.24(6),
Dispensing of Motor Vehicle Fuel, were initially approved into the
Massachusetts SIP on December 14, 1992 (57 FR 58993). Massachusetts'
rule required gasoline dispensing facilities throughout the state to
install Stage II vapor recovery systems.
On May 5, 2015, Massachusetts submitted a SIP revision consisting
of its revised 310 CMR 7.24(6), Dispensing of Motor Vehicle Fuel. This
SIP revision includes regulatory amendments that allow GDFs to
decommission their Stage II vapor recovery systems as of January 2,
2015 and requires that all GDFs equipped with Stage II vapor recovery
systems, decommission their Stage II vapor recovery systems by January
2, 2017.
A Massachusetts GDF equipped with a Stage II vapor recovery system,
and having an annual throughput of less than 500,000 gallons, may apply
for an extension to decommission its Stage II vapor recovery system
based on financial hardship or extenuating circumstances. Massachusetts
DEP may grant an owner, lessee, operator or controller of a GDF making
such request, an extension of up to two years after January 2, 2017.
Any GDF receiving such an extension, is then required to continue to
operate and maintain its Stage II vapor recovery systems in accordance
with Massachusetts' regulations, until the time when such Stage II
vapor recovery system is ever decommissioned.
Massachusetts' May 5, 2015 SIP revision also includes amended
regulation 310 CMR 7.24(3), Distribution of Motor Vehicle Fuel, which
includes requirements for GDFs to upgrade their Stage I vapor recovery
systems to CARB-certified Stage I EVR systems or a Stage I vapor
recovery system composed of EVR system components (Stage I EVR
component systems). As of January 2, 2015, a Stage I EVR system or a
Stage
[[Page 12442]]
I EVR component system is required upon facility start-up for
facilities beginning operation. Also as of January 2, 2015, any
component of a pre-existing Stage I vapor recovery system that is
replaced, is required to be replaced with a CARB-certified Stage I EVR
component. The Massachusetts regulations further require that all Stage
I systems be CARB-certified Stage I EVR systems or Stage I EVR
component systems by January 2, 2022 (seven years from the effective
date of these amended regulations). Furthermore, the revised Stage I
regulations require GDFs with a monthly throughput of 100,000 gallons
or more to maintain Stage I systems that meet the same management
practices required by EPA's National Emissions Standards for Hazardous
Air Pollutants (NESHAP) for Source Category: Gasoline Dispensing
Facilities, 40 CFR part 63, subpart CCCCCC.
In addition, Massachusetts' May 5, 2015 SIP revision also includes
new and amended definitions in 310 CMR 7.00, Air Pollution Control,
that relate to Stage I and Stage II vapor recovery systems and includes
minor clarifying amendments to 310 CMR 7.24(4), Motor Vehicle Fuel Tank
Trucks.
The May 5, 2015 SIP revision also includes a narrative
demonstration supporting the discontinuation of the Massachusetts Stage
II vapor recovery program. This demonstration consists of an analysis
that the Stage II vapor recovery controls provide only de minimis
emission reductions due to the prevalence of ORVR-equipped vehicles.
III. EPA's Evaluation of Massachusetts' SIP Revision
EPA has reviewed Massachusetts revised 310 CMR 7.00, 7.24(3),
7.24(4), and 7.24(6) regulations, as well as the accompanying SIP
narrative, and has concluded that Massachusetts' May 5, 2015 SIP
revision is consistent with EPA's widespread use rule (77 FR 28772; May
16, 2012) and EPA's ``Guidance on Removing Stage II Gasoline Vapor
Control Programs from State Implementation Plans and Assessing
Comparable Measures'' (EPA-457/B-12-001; August 7, 2012), hereafter
referred to as EPA's Guidance Document.
Massachusetts' May 5, 2015 SIP revision includes a CAA section
184(b)(2) ``comparable measures'' demonstration and a CAA section
110(l) anti-back sliding demonstration based on equations in EPA's
Guidance Document. According to these calculations, the potential loss
of refueling emission reductions from removing Stage II vapor recovery
systems in 2013 is 5.12 percent, thus meeting the 10 percent de minimis
recommendation in EPA's Guidance Document. The fact that the
Massachusetts' demonstration is based on 2013, while the regulation
allows decommissioning of Stage II systems beginning in 2015,
represents a conservative estimate as the potential loss of emission
reductions decreases over time as more and more ORVR systems are
phased-in.
In addition, Massachusetts' May 5, 2015 SIP revision also includes
calculations illustrating that the overall emissions effect of removing
the Stage II vapor recovery program would be an increase of about 463
tons of VOC in 2013. EPA's 2011 National Emissions Inventory database,
Version 2, illustrates that Massachusetts' statewide anthropogenic VOC
emissions were about 147,213 tons (see www.epa.gov/ttn/chief/net/2011inventory.html). Therefore the 463 annual tons of VOC emissions
increase calculated by Massachusetts are only about 0.3 percent of the
total anthropogenic VOC emissions in Massachusetts. Also, as noted
above, these foregone emissions reductions in the near term continue to
diminish rapidly over time as ORVR phase-in continues. Thus, EPA
believes that the resulting temporary increases in VOC emissions will
not interfere with attainment or maintenance of the ozone National
Ambient Air Quality Standards (NAAQS).
Furthermore, Appendix Table A-1 of EPA's Guidance Document
illustrates that by the end of 2016 (Massachusetts' requires that all
GDFs decommission their Stage II vapor recovery systems by January 2,
2017), about 85% of the vehicles in the national motor vehicle fleet
will be equipped with ORVR. The number of ORVR-equipped vehicles in
Massachusetts will likely be even higher due to Massachusetts having a
more accelerated motor vehicle fleet turnover when compared to the
national motor vehicle fleet.\2\ Appendix Table A-1 of EPA's Guidance
Document also illustrates that by the end of 2016, almost 89% of
gasoline dispensed nationally will be to ORVR-equipped vehicles, which
is also likely to be higher in Massachusetts due to a newer motor
vehicle fleet.\3\ At that point in time, since a vast majority of
Massachusetts vehicles being refueled at gasoline dispensing facilities
will be equipped with ORVR systems, the ORVR systems will be
controlling the VOC emissions, making Stage II vapor recovery systems a
redundant, and potentially incompatible, emissions control technology
in Massachusetts. Therefore, removing the Stage II systems is not
expected to result in a significant emissions increase, but is expected
to avoid emissions increases resulting from the incompatibility of some
Stage II systems with ORVR controls.
---------------------------------------------------------------------------
\2\ Air Program Support for Stage I and Stage II Programs in
Massachusetts Final Report, Eastern Research Group, Inc. and de la
Torre-Klausmeier Consulting, December 12, 2012, includes an analysis
of vehicle registration data, from the Massachusetts motor vehicle
inspection and maintenance program database, illustrating that 76%
of motor vehicles inspected in 2011 throughout Massachusetts had
ORVR controls. This is much more accelerated than EPA's end of 2011
calendar year national estimate of 67.1% of vehicles in the national
motor vehicle fleet are equipped with ORVR.
\3\ Ibid. In 2013, 84.9% of gasoline dispensed in Massachusetts
was dispensed to ORVR-equipped vehicles. This is slightly more
accelerated than EPA's end of 2013 calendar year national estimate
of 81.0% of fuel dispensed to ORVR-equipped vehicles.
---------------------------------------------------------------------------
With respect to Stage I vapor recovery requirements, Massachusetts'
revised regulation 310 CMR 7.24(3) is more stringent than the
previously approved version of the rule,\4\ thus meeting the CAA
section 110(l) anti-back sliding requirements. As noted above, the
revised rule requires upgrades to a CARB-certified EVR Stage I system
or a Stage I system made up of EVR components by January 2, 2022, with
an earlier January 2, 2015 compliance date in the case of a new
facility or when system components are being replaced. CARB-certified
Stage I EVR systems have been certified to achieve a 98 percent
reduction in VOC emissions, as compared to 95 percent for pre-EVR Stage
I systems. Thus, when pre-EVR Stage I systems in Massachusetts are
replaced with CARB-certified Stage I EVR systems, a greater emission
reduction will be achieved. Also, when a component of a pre-EVR Stage I
systems is replaced with a CARB-certified Stage I EVR component, a
somewhat greater reduction is expected to be achieved. These additional
reductions will further mitigate any temporary declining emissions
increases, which are already de minimis, resulting from removal of
Stage II vapor recovery systems.
---------------------------------------------------------------------------
\4\ EPA's most recent approval of 310 CMR 7.24(3) was on
September 3, 1999 (see 64 FR 48297).
---------------------------------------------------------------------------
Finally, we note that the Massachusetts regulation contains the
following language: ``The provisions and requirements of 310 CMR
7.24(3)(a) and (b) are subject to the enforcement provisions specified
in 310 CMR 7.52.'' EPA notes that this language, which also appears in
other parts of the State's regulation with respect to enforcement of
other specific regulatory provisions, and which EPA is proposing to
approve into the Massachusetts SIP, is not
[[Page 12443]]
intended to, and does not as a matter of law, preclude enforcement of
the SIP provisions in question through any other means authorized by
federal law, including, but not limited to, the CAA.
IV. Proposed Action
EPA is proposing to approve Massachusetts' May 5, 2015 SIP
revision. Specifically, EPA is proposing to approve Massachusetts
revised regulations 310 CMR 7.24(3), Distribution of Motor Vehicle
Fuel, 310 CMR 7.24(4), Motor Vehicle Fuel Tank Trucks, and 310 CMR
7.24(6), Dispensing of Motor Vehicle Fuel, as well as new and revised
definitions, in 310 CMR 7.00, Air Pollution Control, that relate to
Stage I and Stage II vapor recovery systems, and incorporate these
regulations into the Massachusetts SIP. EPA is proposing to approve
this SIP revision because it meets all applicable requirements of the
CAA and EPA guidance, and it will not interfere with any applicable
requirement concerning NAAQS attainment and reasonable further progress
or with any other applicable requirement of the Clean Air Act.
Massachusetts' May 5, 2015 SIP revision satisfies the ``comparable
measures'' requirement of CAA section 184(b)(2), because as stated in
EPA's Guidance Document, ``the comparable measures requirement is
satisfied if phasing out a Stage II control program in a particular
area is estimated to have no, or a de minimis, incremental loss of
area-wide emissions control.'' As noted above, Massachusetts' SIP
revision met de minimis criteria outlined in EPA's Guidance Document.
In addition, since the resulting temporary emissions increase from the
removal of Stage II controls are de minimis, the anti-back sliding
requirements of CAA section 110(l) have also been satisfied.
EPA is soliciting public comments on the issues discussed in this
document or on other relevant matters. These comments will be
considered before taking final action. Interested parties may
participate in the Federal rulemaking procedure by submitting written
comments to this proposed rule by following the instructions listed in
the ADDRESSES section of this Federal Register.
V. Incorporation by Reference
In this rule, the 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, the EPA is proposing to incorporate by
reference Massachusetts' 310 CMR 7.00, Air Pollution Control:
Definitions; 310 CMR 7.24(3), Distribution of Motor Vehicle Fuel; 310
CMR 7.24(4), Motor Vehicle Fuel Tank Trucks; and 310 CMR 7.24(6)
Dispensing of Motor Vehicle Fuel. The EPA has made, and will continue
to make, these documents generally available electronically through
http://www.regulations.gov and at the appropriate EPA office (see the
ADDRESSES section of this preamble for more information).
VI. Statutory and Executive Order Reviews
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this proposed 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 Order 12866 (58
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
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 Clean Air Act; 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, the SIP is not approved to apply on any Indian
reservation land or in any other area where EPA or and Indian tribe has
demonstrated that a tribe has jurisdiction. In those areas of Indian
country, the rule does not have tribal implications and will not impose
substantial direct costs on tribal governments or preempt tribal law as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000.
