[EPA-R03-OAR-2018-0730; FRL-9989-12--Region 3]


Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; Removal of Stage II Gasoline Vapor Recovery Program 
Requirements

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve a state implementation plan (SIP) revision submitted by the 
State of Maryland. This revision seeks to remove requirements for 
gasoline vapor recovery systems installed on gasoline dispensers, the 
purpose of which are to capture emissions from vehicle refueling 
operations (otherwise known as Stage II vapor recovery). Specifically, 
this action would remove from the approved SIP prior approved Stage II 
requirements applicable to new gasoline dispensing facilities (GDFs) 
and existing GDF's undergoing major modification. GDF's will have the 
choice whether to install Stage II at new stations or whether to 
decommission Stage II at existing stations already equipped with Stage 
II. Owners that elect to retain existing Stage II equipment can do so, 
but in doing must continue to test and to maintain or replace existing 
equipment. Maryland's SIP revision includes a demonstration that 
removal of Stage II requirements is consistent with the Clean Air Act 
(CAA) and meets all relevant EPA guidance.

I. Background and Purpose

    On August 25, 2017, the Maryland Department of the Environment 
(MDE) submitted a revision to its SIP. This SIP submittal consists of 
Maryland's revised Stage II requirement regulations, at COMAR 26.11.24, 
Vapor Recovery at Gasoline Dispensing Facilities, which have been 
revised to allow the decommissioning of existing Stage II vapor 
recovery systems and which allows newly constructed GDFs (or those 
undergoing major modifications) the option not to install Stage II 
equipment. The SIP submittal also includes a demonstration that removal 
of Stage II vapor recovery systems in Maryland will not interfere with 
any requirement concerning attainment or reasonable progress of any 
National Ambient Air Quality Standard (NAAQS), or any other applicable 
requirement of the CAA. Maryland's SIP demonstration is also intended 
to show that removal of Stage II requirements is consistent with all 
relevant EPA guidance.
    Stage II vapor recovery is an emission control system that is 
installed on gasoline dispensing equipment at GDFs for the purpose of 
capturing fuel vapor that would otherwise be released from vehicle gas 
tanks into the atmosphere during vehicle refueling. Stage II vapor 
recovery systems installed on dispensing equipment capture these 
refueling emissions at the dispenser and route the refueling vapors 
back to the GDF's underground storage tank, preventing volatile organic 
compounds (VOCs) that comprise these vapors from escaping to the 
atmosphere.
    Beginning in 1998, newly manufactured gasoline-burning cars and 
trucks have been equipped with on-board vapor recovery (ORVR) systems 
that utilize carbon canisters installed directly on the vehicle to 
capture refueling vapors in the vehicle to be later routed to the 
vehicle's engine for combustion during engine operation.
    Stage II vapor recovery systems and ORVR systems were initially 
both required by the 1990 amendments to the CAA. Section 182(b)(3) of 
the CAA requires areas classified as moderate and above ozone 
nonattainment to implement Stage II vapor recovery programs. Also, 
under CAA section 184(b)(2), states in the Northeast 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 cars and trucks (passenger vehicles). EPA adopted these 
requirements in a final action published in the April 6, 1994 Federal 
Register (59 FR 16262 (hereafter referred to as the ORVR rule). Upon 
the effective date of that final rule, moderate ozone nonattainment 
areas were no longer subject to CAA section 182(b)(3) Stage II vapor 
recovery requirements. Under the ORVR rule, new passenger cars built in 
model year 1998 and later were required to be equipped with ORVR 
systems, followed by model year 2001 and later light-duty trucks. ORVR 
equipment has been installed on nearly all new gasoline-powered light-
duty cars, light-

[[Page 3370]]

duty trucks, and heavy-duty vehicles manufactured since 2006.\1\

Programs from State Implementation Plans and Assessing Comparable 
Measures, August 7, 2012, Table A-1.
---------------------------------------------------------------------------

    During the phase-in of ORVR controls, Stage II has provided VOC 
emission reductions in ozone nonattainment areas and in certain areas 
of the OTR. Congress recognized that ORVR systems and Stage II vapor 
recovery systems would over time become largely redundant technologies 
acting to capture the same pollutants. Therefore, Congress provided 
authority in the 1990 amendments to the CAA for EPA to allow states to 
remove Stage II vapor recovery programs from their SIPs upon EPA making 
a finding that ORVR is in ``widespread use.'' EPA issued a widespread 
use finding in a final rule published in the May 16, 2012 Federal 
Register (77 FR 28772), in which EPA determined that ORVR was in 
widespread use on a nationwide basis. EPA estimated that as of the end 
of 2016, more than 88 percent of gasoline refueling nationwide would 
occur with ORVR-equipped vehicles.\2\ Thus, Stage II vapor recovery 
programs have become largely redundant control systems (for ORVR-
equipped vehicles) and as a result, Stage II vapor recovery systems 
achieve ever declining emissions benefits as more ORVR-equipped 
vehicles continue to enter the on-road motor vehicle fleet.\3\ In areas 
where certain types of vacuum-assist Stage II vapor recovery systems 
are used, the interaction between ORVR systems and certain 
configurations of Stage II vapor recovery systems results in the 
reduction of overall control system efficiency in capturing VOC 
refueling emissions compared to what would otherwise be achieved by 
ORVR or Stage II acting in the absence of the other. In its May 16, 
2012 widespread use 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, which among other things, 
exempted 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 program may submit SIP 
revisions that would allow for the phase-out of Stage II vapor recovery 
systems.

II. Summary of Maryland's Stage II Vapor Recovery Program and SIP 
Revisions

    The Maryland portion of the Philadelphia-Wilmington-Trenton, PA-NJ-
DE-MD metropolitan area (hereafter referred to as the Maryland portion 
of the Philadelphia area or the Philadelphia area) and the Baltimore, 
MD metropolitan area were designated by the CAA as severe nonattainment 
for the 1979 1-hour ozone NAAQS.\4\ At the same time, the Maryland 
portion of the Washington, DC-MD-VA metropolitan area (hereafter 
referred to as the Maryland portion of the Washington area, or the 
Washington area) was designated as serious nonattainment under the 1-
hour ozone NAAQS. As a result, Maryland adopted Stage II vapor recovery 
regulations (COMAR 26.11.24) for the Maryland portion of the Washington 
area, the Maryland portion of the Philadelphia area, and for the 
Baltimore, MD area on January 18, 1993 (Maryland Register, February 5, 
1993, Vol. 20, Issue 3). Maryland submitted a revision to EPA on 
January 18, 1993 to request the addition of Maryland Stage II 
requirements to the Maryland SIP, which EPA approved in a final action 
published in the June 9, 1994 Federal Register (59 FR 29730). Maryland 
submitted a revised version of this regulation to EPA as a SIP revision 
on May 23, 2002, which EPA approved in a final action published in the 
May 7, 2003 Federal Register (68 FR 24363). Maryland further amended 
its Stage II regulation on January 26, 2005, and EPA approved that 
revised rule as a revision to the Maryland SIP in a final rule 
published in the May 8, 2006 Federal Register (71 FR 26688).
---------------------------------------------------------------------------

    \4\ 40 CFR 81-321, effective November 15, 1990.
---------------------------------------------------------------------------

    Maryland was also required to adopt Stage II, or comparable 
measures, on a statewide basis under the Stage II OTR provisions of CAA 
section 184(b)(2). Maryland submitted a comparable measures 
demonstration to satisfy the Stage II comparability requirement to EPA 
on November 5, 1997. EPA approved Maryland's November 1997 Stage II 
comparability SIP in a final rule published in the December 9, 1998 
Federal Register (63 FR 67780). Maryland's OTR Stage II comparability 
demonstration relied on five area source VOC control rules as 
comparable measures to Stage II.
    On August 25, 2017, Maryland submitted a SIP revision to EPA 
consisting of revised Stage II requirements (COMAR26.11.24) adopted by 
MDE on November 2, 2015 (state effective November 23, 2015), along with 
a demonstration of the emission impacts of removal of the Stage II 
requirements on affected Maryland areas. The revised rule removes the 
requirements for new Stage II vapor recovery systems in Maryland Stage 
II areas, while allowing GDFs with installed Stage II systems the 
option to decommission their equipment or to retain it. Maryland's 
revised Stage II vapor recovery requirements rule incorporates by 
reference requirements and procedures for stations opting to 
decommission Stage II vapor recovery equipment, based on Section 14 of 
the Petroleum Equipment Institute's Recommended Practices for 
Installation and Testing of Vapor Recovery Systems at Vehicle-Fueling 
Sites, 2009 edition, PEI/RP300-09.
    Under Maryland's revised rule, GDFs opting to continue to operate 
Stage II vapor recovery equipment, as well as those opting to 
decommission Stage II vapor recovery equipment, are subject to 
continued testing requirements (at specified intervals) and 
recordkeeping and reporting requirements related to testing. Maryland's 
revised rule incorporates by reference several test methods applicable 
to GDFs that opt to decommission or to continue to operate Stage II 
vapor recovery systems (Leak Rate and Cracking Pressure of Pressure/
Vacuum Valves, TP-201.1E, California EPA Air Resources Board) and 
(Determination of Vapor Piping Connections to Underground Gasoline 
Storage Tanks (Tie-Tank Test), TP-201.3C, California EPA Air Resources 
Board). For GDFs opting to continue Stage II operation (in addition to 
prior Stage II test requirements), new tests are added to include a 
periodic leak rate and cracking pressure test (per TP-201.1E), as well 
as a tie tank test (per TP-201.3C). GDFs opting to decommission will be 
subject only to the newly added periodic leak rate and cracking 
pressure test (TP-201.1E) and the tie tank test (TP-201.3C). Copies of 
test results must be forwarded to MDE within 30 days of the test.
    The August 25, 2017 SIP revision also includes a demonstration 
supporting the discontinuation of the Maryland Stage II vapor recovery 
program. This demonstration, discussed in greater detail below, 
consists of an analysis that after the year 2016, the overall emissions 
benefits associated with the Stage II program (operated in conjunction 
with ORVR) are overwhelmed by an emissions disbenefit caused by an ORVR 
incompatibility with certain vacuum-assist type Stage II equipment. 
MDE's

[[Page 3371]]

analysis shows that continued operation of the Stage II vapor recovery 
program beyond 2016 actually increases VOC emissions due to the 
incompatibility between certain Stage II and ORVR equipment, coupled 
with the increasing prevalence of ORVR-equipped vehicles. While 
Maryland is not requiring every Stage II-equipped GDF to decommission 
their equipment, it is assumed a majority of existing stations will do 
so upon the removal of state and federal Stage II mandates. Even if all 
stations do no decommission their equipment (or delay doing so), 
overall emission benefits will be improved by the shift to primarily 
ORVR use in current Stage II subject areas.

III. EPA's Evaluation of Maryland's SIP Revision

    EPA has reviewed Maryland's revised COMAR 26.11.24, Vapor Recovery 
at Gasoline Dispensing Facilities, and accompanying SIP narrative, and 
has concluded that Maryland's August 25, 2017 SIP revision is 
consistent with EPA's widespread use rule (77 FR 28772, May 16, 2012) 
and with EPA's ``Guidance on Removing Stage II Gasoline Vapor Control 
Programs from State Implementation Plan and Assessing Comparable 
Measures'' (EPA-457/B-12-001; August 7, 2012), hereafter referred to as 
EPA's Stage II Removal Guidance.
    Maryland's August 25, 2017 SIP revision includes a demonstration 
supporting the discontinuation of the Maryland Stage II vapor recovery 
program, in compliance with the requirements of the CAA sections 110(l) 
requirement that revision of the SIP will not interfere with attainment 
of or reasonable further progress towards attainment of any NAAQS or 
any other applicable CAA requirement. This demonstration was prepared 
by MDE based on relevant equations provided in EPA's Stage II Removal 
Guidance. From this analysis, Maryland determined that by 2016 the 
emissions benefits from the Stage II vapor recovery program (in 
conjunction with ORVR) will be overwhelmed by the emission disbenefits 
stemming from an incompatibility between certain Stage II vacuum-assist 
based systems and ORVR. Beyond 2016, the continuation of Stage II vapor 
recovery requirements would increase emissions in the Maryland portions 
of all analyzed areas, as summarized in Table 1. Based on this 
analysis, Maryland elected to allow decommissioning of Stage II vapor 
recovery systems beginning in October 2016.

    In evaluating whether a given SIP revision would interfere with 
attainment of a NAAQS, EPA generally considers whether the SIP revision 
will allow for an increase in actual emission into the air over what is 
allowed under the existing EPA-approved SIP. EPA has not required that 
states produce a new complete attainment demonstration for every SIP 
revision, provided that the status quo air quality is preserved. See 
e.g., Kentucky Resources Council, Inc. v. EPA, 467 F.3d 986 (6th Cir. 
2006).\5\ EPA believes that a planned Stage II decommissioning that is 
shown not to result in an increase in areawide VOC emissions would be 
consistent with the conditions of CAA section 110(l), and would not 
jeopardize attainment or maintenance of an area that formerly relied 
upon Stage II emission reductions in the approved SIP. Maryland has 
demonstrated that Stage II vapor recovery will no longer provide 
emission reductions when compared to ORVR without Stage II vapor 
recovery in all Maryland ozone nonattainment areas. Since 2016, Stage 
II vapor recovery (operated in conjunction with ORVR) has been shown by 
Maryland to result in increased VOC emissions in Maryland's three ozone 
nonattainment areas--due to incompatibilities between certain types of 
Stage II equipment and vehicle ORVR systems. Therefore, EPA believes 
discontinuance of Stage II in Maryland's three ozone nonattainment 
areas will not interfere with those areas' ability to attain or 
maintain the NAAQS, or to provide reasonable further progress in 
meeting the NAAQS.
---------------------------------------------------------------------------

    \5\ EPA Guidance on Removing Stage II Gasoline Vapor Control 
Programs from State Implementation Plans and Assessing Comparable 
Measures, August 7, 2012, Section 2.2.

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

[[Page 3372]]

    States in the OTR defined by the CAA remain obligated under CAA 
section 184(b)(2) to implement (on a statewide basis) either a Stage II 
vapor recovery program, or other measures capable of achieving emission 
reductions ``comparable to those achievable'' by Stage II vapor 
recovery. EPA issued guidance on this OTR comparability demonstration 
in 1995 and later updated that guidance as part of its August 2012 
Stage II Removal Guidance--in light of the decreasing role of Stage II 
as a means of controlling refueling emissions and the increasing 
prominence of ORVR-equipped vehicles.
    Maryland submitted a comparable measures SIP revision to EPA on 
November 5, 1997 demonstrating that control measures already 
implemented in those counties in Maryland not subject to Stage II vapor 
recovery under CAA section 182(b)(3) achieved comparable emission 
reductions to Stage II vapor recovery. Maryland's chosen Stage II 
comparable measures included non-point, or area source, controls on: 
Cold and vapor degreasing operations, lithographic printing, screen 
printing, expandable polystyrene operations, and vehicle refinishing. 
To address areas in Maryland subject to Stage II or a comparable 
measure (as a result of the CAA section 184 requirements specific to 
OTR states), EPA approved Maryland's November 1997 Stage II 
comparability SIP for attainment and marginal ozone nonattainment 
counties in a final action published in the December 9, 1998 Federal 
Register (63 FR 67780). Maryland is not required to further demonstrate 
Stage II comparability for those counties as that action remains in 
effect.
    However, Maryland is required to newly demonstrate Stage II 
comparability for the Philadelphia, Baltimore, and Washington areas--
where Stage II vapor recovery was previously mandated by CAA section 
182(b)(3) prior to EPA's issuance of its ORVR ``widespread use'' 
determination. The 110(l) demonstration in Maryland's August 25, 2017 
SIP revision shows that Stage II no longer yields VOC emissions 
benefits in these three nonattainment areas after 2016, when operated 
in conjunction with ORVR. Therefore, since Stage II provides no 
additional benefits beyond ORVR (and results in increases in VOC 
emissions beyond 2016) in these three nonattainment areas, EPA believes 
that removal of Stage II after 2016 satisfies the Stage II 
comparability requirement of section 184 for these three ozone 
nonattainment areas.
    In addition to the CAA section 182 and 184 requirements applicable 
to Stage II vapor recovery, CAA section 193 prohibits modification of 
any control requirement in effect before enactment of the CAA of 1990 
(i.e., November 15, 1990) in a current nonattainment area--unless 
modification ``ensures equivalent or greater emission reductions.'' 
Therefore, a Stage II vapor recovery control program implemented under 
a SIP prior to November 1990 may not be removed from the SIP until 
another requirement is shown to achieve equal or greater emissions 
reductions than Stage II vapor recovery. Maryland did not have a Stage 
II program prior to November 15, 1990, so Stage II was not a part of 
the Maryland SIP prior to that date. Therefore, this ``general savings 
clause'' requirement of CAA section 193 does not apply to Maryland or 
to this action.

IV. Proposed Action

    EPA is proposing to approve Maryland's August 25, 2017 SIP revision 
for statewide removal of Stage II vapor recovery requirements. 
Specifically, EPA is proposing to approve Maryland's revised COMAR 
26.11.24, Vapor Recovery at Gasoline Dispensing Facilities, and 
incorporate it into the Maryland SIP. EPA is proposing to approve this 
SIP revision because it meets all applicable requirements of the Clean 
Air Act and relevant EPA guidance and because approval of this SIP 
revision will not interfere with attainment or maintenance of the ozone 
NAAQS.
    EPA is soliciting public comments on the issues discussed in this 
notice or other relevant matters. These comments will be considered 
before taking final action.

V. Incorporation by Reference

    In this proposed rule, EPA proposes to include in our subsequent 
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 the State of Maryland's revised 
COMAR 26.11.24 Vapor Recovery at Gasoline Dispensing Facilities 
(effective date November 23, 2015), which includes amendments to 
Regulations .01, .01-1, .02, .03, .03-1, .04, and .07 and the addition 
of Regulation .03-1. EPA has made, and will continue to make, these

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 CAA and applicable 
federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
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 SIP approvals are exempted 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 (Public Law 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 rule to remove Maryland Stage II vapor 
recovery requirements does not have tribal implications as specified by

[[Page 3373]]

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.
