Transport Region, Stage II 

Dear Ms. Esher: 

Pursuant to the requirements of § 11 0 of the federal Clean Air Act, we are officially 

requesting approval of a revision to the Commonwealth of Virginia State Implementation Plan 

(SIP) approved and submitted under the authority of§ 10.1-1185 of the Code of Virginia and in 

accordance with the requirements of 40 CFR Part 51 (Requirements for Preparation, Adoption, 

and Submittal oflmplementation Plans). 

On May 16, 2012 (77 FR 28772), the U.S. Environmental Protection Agency (EPA) 

determined that onboard refueling vapor recovery (ORVR) technology is in widespread use 

throughout the motor vehicle fleet for purposes of controlling motor vehicle refueling emissions, 

and, therefore, is waiving the requirement for states to implement Stage II gasoline vapor 

recovery systems at gasoline dispensing facilities. A state that had been previously required to 

implement a Stage II program may now take appropriate action to remove the program from its 

SIP. Phasing out the use of Stage II systems may lead to long-term cost savings for gas station 

owners and operators while air quality protections are maintained. 

This submittal revises the SIP for the northern Virginia jurisdictions located in the Ozone 

Transport Region (OTR) such that Stage II vapor recovery systems on gasoline dispensing 

stations are no longer required after December 31, 2013. The Virginia jurisdictions that are part 

ofthe OTR, as defined under §184(a) ofthe Act, are the counties of Stafford, Arlington, Fairfax, 

Loudoun, and Prince William, and the cities of Alexandria, Fairfax, Falls Church, Manassas, and 

Manassas Park. These localities, with the exception of Stafford County, make up the Northern 

Virginia ozone nonattainment area, which is currently classified as marginal for the 2008 ozone 
NAAQS. The Fredericksburg area, including Stafford County, is designated as attainment for the 

2008 ozone NAAQS. The Commonwealth has determined that Stage II is no longer needed in the 

areas' attainment and maintenance plans, which are approved into the Virginia SIP at 40 CFR 

52.2420( e). 

Removing this requirement does not interfere with maintenance of any ozone NAAQS. 

Federal guidance indicates that incompatibility excess emissions negate the benefit of Stage II in 

these jurisdictions. Modeling studies also show that reductions in nitrogen oxides (NOx) are 10 

to 1,000 times more effective than VOC reductions in lowering ozone concentrations in the 

Commonwealth. This SIP revision satisfies the requirements of the widespread use 

determination of 40 CFR 51.126 as well as in EPA guidance, the noninterference requirements of 

§ 11 0(1) of the Act, and the comparable reduction requirements of§ 184(b )(2) of the Act. 

Enclosed are the following: 

1. SIP submittal. 

2. Certification of public participation activities. 

3. Record of hearing and summary of comment. 

4. An electronic copy (CD) of the complete submittal. This electronic copy is an exact

STATE IMPLEMENTATION PLAN REVISION

REMOVAL OF STAGE II GASOLINE VAPOR CONTROLS AT GASOLINE 

DISPENSING FACILITIES LOCATED IN VIRGINIA JURISDICTIONS DEFINED AS 

PART OF THE OZONE TRANSPORT REGION

Overview

The purpose of this document is to revise the Commonwealth's ozone attainment and 

maintenance plans for the portions of Virginia that are part of the Ozone Transport 

Region (OTR) such that Stage II vapor recovery systems (VRS) are no longer required 

beginning on January 1, 2014.

The state implementation plan (SIP) submittals for the 1990 ozone National Ambient Air 

Quality Standards (NAAQS) required the implementation of the Stage II program in the 

Virginia OTR jurisdictions. Later submittals quantified the benefits of this program, 

which was fully implemented by those submittal dates. Since the development of these 

submittals, the United States Environmental Protection Agency (EPA) has determined 

that onboard refueling vapor recovery (ORVR) is in widespread use. The

Commonwealth has examined whether Stage II is still necessary for ozone control 

purposes and has determined that Stage II is no longer needed in the area's plans, 

which are approved into the Virginia SIP at 40 CFR 52.2420(e).

Removing this control requirement does not interfere with maintenance of any ozone 

NAAQS. EPA guidance suggests that after December 31, 2013, incompatibility excess 

emissions resulting from the use of certain Stage II VRS that are not compatible with 

vehicles equipped with ORVR offset emission reductions from Stage II controls. Volatile 

organic compound (VOC) emissions are a precursor to ozone formation in the ambient 

air; however, in this region of the country, reductions in VOCs are only marginally 

effective for reducing ozone concentrations. Modeling studies show that reductions in 

nitrogen oxides (NOX) are 10 to 1,000 times more effective in reducing ozone 

concentrations in the Washington DC-MD-VA and Fredericksburg area than VOC 

reductions. Therefore, this SIP revision satisfies all requirements in EPA guidance 

regarding the removal of Stage II vapor recovery system requirements and § 110(l) of 

the federal Clean Air Act (CAA). 

This SIP revision also satisfies all requirements in EPA guidance regarding the 

comparability analysis required by § 184(b)(2) of the CAA. The analysis provided 

herein shows that the incremental emissions control achieved by Stage II VRS beyond 

ORVR is less than 10% of the area-wide emissions inventory associated with refueling 

highway motor vehicles. In fact, this analysis, which is based on EPA’s guidance, 

shows that incompatibility excess emissions resulting from the use of certain Stage II 
2

VRS that are not compatible with vehicles equipped with ORVR fully offset emission 

reductions from Stage II controls after December 31, 2013.

This document and supporting evaluations are based on 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).

Equipment and Technology Description

Stage II VRS

Gasoline dispensing facilities (GDF) generally store fuel in underground storage tanks 

(UST) and dispense this fuel to individual vehicle fuel tanks. As the vehicle tanks fill, 

the liquid gasoline displaces a commensurate amount of vapor that contains air and 

VOC. Stage II VRS capture these displaced vapors emerging from inside fuel tanks as 

gasoline is dispensed into the tank and return that vapor to the UST. In the UST, vapor 

either condenses to liquid form or is removed and transported to the fuel terminal by 

tanker refueling trucks. Fuel terminals vent the vapors to either a vapor combustion 

system, where the vapors are destroyed via oxidation, or a vapor recovery system, 

where the vapors are captured and regenerated as a liquid via carbon bed technology.

GDFs employ two different types of Stage II systems: balance-type systems and 

vacuum assist-type systems. Balance systems rely on pressure differentials to transfer 

vapor from the vehicle fuel tank to the UST. Vacuum assist-type systems rely on a 

vacuum source to help move the vapors out of the vehicle tank and into the UST. 

Passive vacuum-assist systems use an electrically driven vacuum pump located in the 

dispenser cabinet. An active system maintains a vacuum through a central pump on 

the entire Stage II VRS to recover vapors from the entire system. A key feature of 

vacuum assist system design and operation is the design air/liquid (A/L) volume ratio. 

This ratio measures the volume of air or vapor returned to the tank against the volume 

of liquid dispensed. The larger the design A/L ratio, the greater the amount of air 

returned to the UST.

ORVR

This method of vapor recovery is a system employed on gasoline-powered highway 

motor vehicles to capture gasoline vapors displaced from a vehicle fuel tank during 

refueling events. ORVR systems are comprised of an activated carbon canister that 

captures the displaced vapor during refueling. While driving, a portion of the engine 

intake air regenerates the carbon, and the hydrocarbons desorb and burn as fuel in the 

engine. Section 202(a)(6) of the CAA required the development and implementation of 

this technology. Federal regulations (40 CFR Part 86) mandated these systems for 

light-duty vehicles beginning in the 1998 model year, with 40%, 80%, and 100% of new

light-duty vehicle production having ORVR systems in 1998, 1999, and 2000, 

respectively. Federal regulations now require ORVR installation on all gasoline-
3

powered passenger cars, light trucks, and complete heavy trucks of less than 14,000 

pounds gross vehicle weight rating. EPA estimates that ORVR-equipped vehicle 

percentages nationwide will exceed 80% of all highway gasoline vehicles and 85% of all 

gasoline dispensed during 2015. 

ORVR/Stage II Compatibility

When refueling an ORVR-vehicle with a vacuum assist-type Stage II equipped 

dispenser, compatibility problems may result in an increase in emissions from the UST 

vent pipe and other system fugitive emissions. In an ORVR-equipped vehicle, the liquid 

seal in the fill pipe blocks the vapor flow from the vehicle fuel tank, and fresh air drawn 

into the UST enhances gasoline evaporation in the UST. This additional evaporation 

increases pressure in the UST, and as tank pressure exceeds the rating of the 

pressure/vacuum valve, the valve allows vapor to escape to the atmosphere. The 

magnitude of these excess emissions at a specific facility is a function of the A/L ratio at 

the dispenser as well as other factors, such as gasoline throughput dispensed to 

ORVR-equipped vehicles.

Balance-type Stage II equipped dispensers are compatible with ORVR equipment and 

do not cause these excess emissions. Also, not all vacuum assist-type Stage II 

equipment causes these excess emissions. Some vacuum assist-type Stage II 

equipment maintains A/L ratios near unity (1/1) and therefore do not exhibit these 

increases. Other assist-type Stage II equipment determines when an ORVR vehicle is 

being refueled and reduces the A/L ratio to avoid compatibility emission effects.

Implementation of Stage II in the Virginia Jurisdictions Included in the OTR

Under the 1990 1-hour ozone NAAQS of 0.12 parts per million (ppm) or 124 parts per 

billion (ppb), EPA originally designated the OTR jurisdictions in Virginia as a serious

nonattainment area on November 6, 1991 (56 FR 56694). These localities included the 

counties of Stafford, Arlington, Fairfax, Loudoun, and Prince William, and the cities of 

Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park. These localities, 

along with jurisdictions in southern Maryland and the District of Columbia, made up the 

Washington DC-MD-VA 1990 ozone NAAQS nonattainment area. The area submitted 

an attainment plan for the 1990 ozone NAAQS on December 19, 1997, and EPA gave 

conditional approval of this plan on April 17, 2003 (68 FR 19106). After EPA 

reclassified the area to severe on November 13, 2002 (67 FR 68805), the area 

submitted a severe area attainment plan on February 25, 2004, which EPA 

subsequently approved on May 13, 2005 (70 FR 25688). The area’s air quality 

improved so that the area met the severe area compliance date of November 15, 2005, 

and EPA published a final determination of attainment for the 1990 ozone NAAQS for 

the area on July 25, 2008 (73 FR 43360). EPA revoked the 1990 ozone NAAQS on 

June 15, 2005. 
4

EPA revised the ozone NAAQS on July 18, 1997 (62 FR 38856) by lowering the 

standard to 0.08 ppm or 84 ppb over an 8-hour average. EPA grouped Stafford County

into the Fredericksburg 1997 ozone NAAQS moderate nonattainment area on April 30, 

2004 (69 FR 23941). In addition to Stafford County, this area also includes the City of 

Fredericksburg and Spotsylvania County. Air quality improved and Virginia submitted a

1997 ozone NAAQS redesignation request and maintenance plan on September 28, 

2005, for which EPA published final approval on December 23, 2005 (70 FR 76165). 

EPA also designated the Washington DC-MD-VA area as nonattainment for the 1997 

ozone NAAQS on April 30, 2004 (69 FR 23941), with a classification of moderate. 

Under this standard, the Virginia portion of the Washington DC-MD-VA area consisted 

of the counties of Arlington, Fairfax, Loudoun, and Prince William, and the cities of 

Fairfax, Falls Church, Manassas, Manassas Park, and Alexandria. Virginia submitted 

an attainment plan for this standard on June 12, 2007, and EPA proposed approval of 

this plan on March 20, 2013 (78 FR 17161). Air quality in the region has improved 

significantly, and on February 28, 2012 (77 FR 11739), EPA published a clean data 

determination for the area as well as a final determination of attainment for the 1997 

ozone NAAQS by the federally mandated attainment date of June 15, 2010.

The 1997 ozone NAAQS is not yet revoked. EPA proposed the 2008 ozone NAAQS 

implementation rule on June 6, 2013 (78 FR 34178). This proposal suggests that the 

revocation date will be the publication date for the final 2008 ozone NAAQS 

implementation rule. 

On May 21, 2012 (77 FR 30160), the Fredericksburg area, including Stafford County, 

was designated as attainment for the 2008 ozone NAAQS. In this rulemaking, EPA also

designated the Washington DC-MD-VA area as nonattainment for the 2008 ozone 

NAAQS, with a classification of marginal. The Virginia portion of the Washington DCMD-VA area for the 2008 ozone NAAQS consists of the counties of Arlington, Fairfax, 

Loudoun and Prince William and the cities of Fairfax, Falls Church, Manassas, 

Manassas Park, and Alexandria. 

At the time the 1990 ozone NAAQS attainment plan was developed, Stage II 

requirements were mandatory for areas classified as moderate or higher for the 1990

ozone NAAQS under § 182(b)(3):

(A) Gasoline Vapor Recovery.—General Rule.—Not later than 2 years after the date of the 

enactment of the Clean Air Act Amendments of 1990, the State shall submit a revision to the 

applicable implementation plan to require all owners or operators of gasoline dispensing systems 

to install and operate, by the date prescribed under subparagraph (B), a system for gasoline 

vapor recovery of emissions from the fueling of motor vehicles. The Administrator shall issue 

guidance as appropriate as to the effectiveness of such system. This subparagraph shall apply 

only to facilities which sell more than 10,000 gallons of gasoline per month (50,000 gallons per 

month in the case of independent small business marketers of gasoline as defined in section 

325). 

At that time, EPA had not yet promulgated regulations for ORVR systems on light duty 

trucks and passenger vehicles, nor had EPA made a determination of widespread use. 
5

Therefore, the removal of the Stage II mandate on serious and severe nonattainment 

areas had not yet occurred, as provided in § 202(a)(6):

(6) Onboard Vapor Recovery.—...The requirements of section 182(b)(3) (related to stage II 

gasoline vapor recover) for areas classified under section 181 as moderate for ozone shall not 

apply after promulgation of such standards and the Administrator may, by rule, revise or waive 

the application of the requirements of such section 182(b)(3) for areas classified under section 

181 as Serious, Severe, or Extreme for ozone, as appropriate, after such time as the 

Administrator determines that onboard emissions control systems required under this paragraph 

are in widespread use throughout the motor vehicle fleet.

EPA adopted the ORVR requirements in 1994 under 40 CFR Part 86 (59 FR 16262). 

These regulations phased in the use of ORVR on new passenger vehicles beginning 

with model year 1998 and on light duty trucks and most heavy duty gasoline powered 

vehicles beginning with model year 2001. ORVR equipment has been installed on 

nearly all new gasoline-powered light-duty vehicles, light-duty trucks, and heavy-duty 

vehicles since 2006. EPA published the final rule determining widespread use of ORVR 

on May 16, 2012 (77 FR 28772).

The CAA also obligated Virginia jurisdictions located in the OTR to implement Stage II 

VRS or comparable measures in § 184(b)(2):

(2) Within 3 years after the date of the enactment of the Clean Air Act Amendments of 1990, the 

Administrator shall complete a study identifying control measures capable of achieving emission 

reductions comparable to those achievable through vehicle refueling controls contained in section 

182(b)(3), and such measures or such vehicle refueling controls shall be implemented in 

accordance with the provisions of this section. Not withstanding other deadlines in this section, 

the applicable implementation plan shall be revised to reflect such measures within 1 year of 

completion of the study. ...

The plans for Virginia jurisdictions of the Washington DC-MD-VA 1990 and 1997 ozone 

nonattainment areas, as well as the maintenance plan for the Fredericksburg 1997 

ozone maintenance area, contain Stage II VRS emission reduction benefits. The 1990

ozone NAAQS attainment plan for the Washington DC-MD-VA area required the 

implementation of Stage II controls, and subsequent submittals included estimated 

emission reductions from the implemented control program. The out year in the 

Fredericksburg 1997 ozone maintenance plan is 2015 so that removing Stage II control 

requirements after December 31, 2013, may only affect the final two years of the 

maintenance plan, 2014 and 2015. However, due to the incompatibility excess 

emissions resulting from the implementation of both Stage II VRS and ORVR, removing 

State II control requirements after December 31, 2013, would not change the 

conclusions of the maintenance plan: air quality in the Fredericksburg area complies 

with the 1997 ozone NAAQS and air quality will continue to improve. The 

incompatibility excess emissions also ensure that removing Stage II VRS requirements 

from the Washington DC-MD-VA area’s attainment plans will not impact air quality. 

Therefore, the Virginia OTC jurisdictions comply with requirements under the 

interference clause of § 110(l) and the comparability clause under § 184(b)(2).
6

The Stage II VRS program in the Virginia OTR jurisdictions applies to gasoline 

dispensing facilities that have a monthly throughput of at least 10,000 gallons of 

gasoline. Exempt from this program are independent small business gasoline 

marketers with an average monthly throughput of 50,000 gallons or less. The Stage II 

VRS program is found in 9VAC5-40-5220 F (Transfer of gasoline ─ gasoline dispensing 

facilities ─ Stage II vapor recovery systems) of Article 37, Emission Standards For 

Petroleum Liquid Storage and Transfer Operations, of Part II of 9VAC5-40 (Existing 

Stationary Sources).

To remove Stage II control requirements from the Virginia SIP pertinent to the Virginia 

OTR jurisdictions, this submittal demonstrates compliance with the noninterference 

clause of the CAA, specifically § 110(l):

Each revision to an implementation plan submitted by a State under this Act shall be adopted by 

such State after reasonable notice and public hearing. The Administrator shall not approve a 

revision of a plan if the revision would interfere with any applicable requirement concerning 

attainment and reasonable further progress (as defined in section 171), or any other applicable 

requirement of this Act. 

This submittal also demonstrates comparability under § 184(b)(2) since the incremental 

emissions control that Stage II achieves beyond ORVR is de minimis, as defined by 

EPA guidance. EPA’s guidance notes that such incremental emissions control is de 

minimis if the Stage II control achieved is less than 10% of the area-wide emissions 

inventory associated with refueling highway motor vehicles. These estimates are areaspecific since they rely on an area’s fleet profile and Stage II control program 

parameters.

Section 110(l) Noninterference and Section 184(b)(2) Comparable Measures 

Analyses

Federal Calculations

EPA's "Guidance on Removing Stage II Gasoline Vapor Control Programs from State 

Implementation Plans and Assessing Comparable Measures" provides information on 

the following:

• Determining the projected penetration of ORVR-equipped vehicles;

• Calculating incompatibility excess emissions; and

• Calculating the increment, which identifies the annual area-wide emissions 

control gain or loss from Stage II installations as ORVR technology phases into 

the fleet.

For this effort, the Virginia Department of Motor Vehicles (DMV) supplied vehicle 

population data including vehicle mix and fleet age information for each jurisdiction. 

The Virginia Department of Transportation (VDOT) supplied vehicle miles travelled 

(VMT), average road speeds, and VMT distributions. These calculations assume 90% 
7

rule penetration for Stage II VRS or that 90% of the gasoline sold in the area is from 

dispensers equipped with Stage II VRS, as provided in EPA guidance. These 

calculations also assume either a 77% or 56% in-use control efficiency for Stage II VRS, 

as described in EPA's "Procedures for Emissions Inventory Preparation, Volume IV: 

Mobile Sources" (EPA420-R-92-009, December 1992). Attachment A provides the 

details of these calculations.

Projected Penetration of ORVR in the Virginia Jurisdictions Located in the OTR and 

Widespread Use

In the final May 16, 2012, ORVR widespread use determination analysis (77 FR 28772), 

EPA defined a percentage of 75 or greater as substantial enough to be considered 

widespread. Multiple options exist for calculating this percentage. This percentage may 

represent the fraction of gasoline dispensed to ORVR-equipped vehicles, the percent of 

VMT by ORVR-equipped vehicles, or the percent of ORVR-equipped vehicles in the 

fleet. EPA methods in the final rule and local input data for each Virginia OTR 

jurisdiction were used to project the penetration of ORVR in the local fleet through 

calendar year 2030 for comparison to these metrics.

Table 1 summarizes the results of the calculations in Attachment A. For each 

calculation basis, Table 1 presents the end of the calendar year in which the EPA 

threshold of 75% is reached or exceeded. This analysis estimates that the percentage 

of ORVR-equipped vehicles in the local fleet (77.6%), the percentage of VMT by ORVRequipped vehicles (79.3%), and the amount of gasoline dispensed into ORVR-equipped 

vehicles (77.3%) exceeded 75% by the end of 2011, 2009, and 2009 respectively. 

Using the latest year for the benchmark of widespread use, which is vehicle population 

percentage, the area achieved widespread use in year 2011.

Table 1: Widespread Use Analysis

Calculation Basis Year Percentage

Vehicle Population Percentage 2011 77.6%

VMT Percentage 2009 79.3%

Gasoline Dispensed Percentage 2009 77.3%

EPA has also defined, in 77 FR 28772, an alternative approach for estimating ORVR

widespread use. This approach assumes that widespread use occurs when the 

emission reductions achieved by ORVR alone are equivalent to the reductions achieved 

by Stage II alone. As noted in this final rule, EPA estimates that 90% of the gasoline 

sold in the area is from dispensers equipped with Stage II VRS. As described in EPA’s 

"Procedures for Emission Inventory Preparation, Volume IV: Mobile Sources," an in-use 

control efficiency of 77% is assumed for Stage II VRS. Multiplying this estimated control

efficiency (77%) by the estimated fraction of gasoline sold from dispensers equipped 

with Stage II VRS (90%) yields an estimated area-wide Stage II program control 

efficiency of 69.3%. The emission reductions achieved by ORVR alone exceeded this 

percentage by the end of calendar year 2008 (75.5%).
8

The worksheet entitled, "NoVA-MOVES ORVR Penetration" in Attachment A contains 

the details of these calculations.

Increment Calculations

In EPA’s guidance, the overall increment of an area identifies the annual area-wide 

emission control gain from Stage II VRS as ORVR technology phases in. Therefore, 

the increment also indicates the emission reduction potential loss in any particular year 

from removing Stage II requirements. This equation is important for assessing and 

demonstrating compliance with the noninterference provisions of CAA § 110(l). It is 

also important for determining compliance with CAA § 184(b)(2) comparability 

requirements. When an area’s increment calculations show that the emission control 

achieved by Stage II VRS beyond that achieved by ORVR is less than 10%, EPA’s 

guidance states that the area satisfies comparability requirements. 

EPA’s guidance notes that the number of non-ORVR equipped vehicles is small and 

declining. Therefore, the amount of emission reduction achievable from Stage II alone is 

also declining. Due to the vacuum-assist compatibility factor, the incompatibility excess 

emissions that are created from Stage II VRS used on ORVR-equipped vehicles 

eventually overwhelms the emission reductions achieved from the use of Stage II VRS 

on non-ORVR-equipped vehicles. At the point in time where incompatibility excess 

emissions equal Stage II VRS emission reductions, removal of the Stage II VRS 

program will not interference with maintenance of any NAAQS. Therefore, such a 

demonstration satisfies § 110(l) noninterference requirements, as noted in EPA’s 

guidance. At this same time, the emission control achieved by Stage II beyond that 

achieved by ORVR is zero, and therefore removal of Stage II VRS meets comparability

requirements in § 184(b)(2).

EPA’s guidance describes the methodology for calculating the increment in any year i 

using the following formula and variable definitions:

Incrementi = (QSII)(1-QORVRi)(ηiuSII)-(QSIIva)(CFi)

QSII This variable represents the fraction of gasoline throughput covered by 

Stage II, and data for this variable are located in Table 2 of EPA’s 

guidance.

QORVRi This variable represents the fraction of gasoline dispensed to ORVRequipped vehicles in year i. Development of this information relies on 

MOVES2010a with local input data from the OTR jurisdictions. See the 

table entitled, "Projected Penetration of ORVR in the NoVA Area" in 

Attachment A.

ηiuSII This variable represents the Stage II control efficiency, which for these 

jurisdictions is 77%.
9

QSIIva This variable represents the fraction of gasoline dispensed by vacuum 

assist Stage II systems. EPA’s guidance document provides regional data 

for this variable in Table A-6.

CFi This variable, called the compatibility factor, represents the increase in 

UST vent pipe emissions over normal breathing/emptying loss emissions. 

It is calculated by multiplying the fraction of annual area-wide VMT 

traveled by ORVR-equipped vehicles with a constant term, 0.07645. 

Table 2 provides the summary of the increment calculations assuming a 77% Stage II 

VRS control efficiency in this area. This control efficiency and the equations in EPA’s 

guidance indicate that incompatibility excess emissions will overwhelm and exceed the 

Stage II VRS benefit after December 31, 2013. The negative value in the table below 

denotes this situation.

Table 2: Increment Calculations Using 77% Control Efficiency for Stage II VRS

2008 0.13760 2015 -0.02785

2009 0.10597 2016 -0.03673

2013 -0.00128 2030 -0.06204

2014 -0.01632

Table 3 provides the summary of the incremental calculations assuming a 56% control 

efficiency in this area. The equations in EPA’s guidance used in conjunction with the 

lower control efficiency indicate that incompatibility excess emissions overwhelm the 

Stage II VRS benefit after December 31, 2012.

Table 3: Increment Calculations Using 56% Control Efficiency for Stage II VRS

Year Increment Year Increment

2008 0.08684 2015 -0.03725

2011 0.01534 2018 -0.05245

2012 -0.00275 2020 -0.05702

2013 -0.01736 2030 -0.06279

2014 -0.02862

These calculations and the more conservative control efficiency estimate of 77% for 

Stage II VRS demonstrate that eliminating the Stage II VRS requirements after

December 31, 2013, will result in a net improvement in emission reductions and will not 

violate the requirements of § 110(l) in the CAA. These calculations also show that the 
10

requirements of a comparable program, as noted in § 184(b)(2) of the CAA, have been 

met. These calculations demonstrate that eliminating the Stage II VRS requirements 

after December 31, 2013, results in no loss of VOC control due to incompatibility excess 

emissions. Therefore, removal of the Stage II program in this area beginning January 1, 

2014, will not infringe on any requirements in § 184(b)(2) of the CAA.

Attachment A provides these calculations in the worksheet entitled, "NoVA-Increment 

Equation."

Stage II and Excess Vent Emissions

EPA’s guidance offers two methodologies for evaluating the impact of removing Stage II 

VRS requirements on the area-wide VOC inventory in terms of tons of VOC emitted. 

The first methodology relies on the increment value to calculate the total impact of this 

change:

Tonsi = (Incrementi)(GCi)(EF)

GCi This variable represents the projected gasoline consumption in gallons for 

the particular year i. EPA’s guidance provides data for various areas of 

the country in Table A-4.

EF This variable represents the uncontrolled displacement refueling emission 

factor in grams per gallon. This variable is dependent on the Reid vapor 

pressure of the fuel, the dispensed fuel temperature, and the difference 

between tank fuel temperature and the dispensed fuel temperature.

Table 4 presents the results of this equation, as applied to the Virginia OTR 

jurisdictions. By December 31, 2013, this equation shows that incompatibility excess 

emissions overwhelm Stage II VRS benefits by 0.01 tons/day of VOC.

Attachment A provides the details of these calculations in the worksheet entitled,

"NoVA-Tons Equation."

EPA’s guidance also provides formulas for calculating incompatibility excess emissions 

using either the fraction of annual VMT traveled by ORVR-equipped vehicles or the 

fraction of gasoline dispensed to ORVR-equipped vehicles. MOVES2010a may be 

used to develop Stage II emissions benefit. Comparing the values for this benefit in any 

particular year to the incompatibility excess emissions values generated by EPA’s 

formulas is another approach to determining the impact on the overall VOC emissions 

inventory from the continued implementation of the Stage II VRS program. Table 5

summarizes the results of the calculations detailed in Attachment A for incompatibility 

excess emissions, Stage II benefit as calculated by MOVES2010a, and the total benefit 

from the implementation of both the Stage II and the ORVR control programs. Using 

these methodologies, the incompatibility excess emissions overwhelm the benefit of 

Stage II VRS in the 2014 timeframe, as noted by the negative numbers in the "Stage

II/ORVR Benefit" columns in Table 5.

Expected Ozone Air Quality Impacts From VOC Reductions

Several studies have shown that the VOC reductions attributable to future 

implementation of Stage II VRS are insignificant to the formation of ozone for this area. 

VOC sensitivity runs using CMAQ suggest that these source sector emissions do not 

significantly contribute to ozone formation and, in some cases, may result in a small 

ozone air quality disbenefit. This information further supports the assertion that the 

proposed removal of the Stage II VRS requirements fully satisfies all requirements of §

110(l). The contribution of emissions from this source sector to the total VOC inventory 

on a regional and statewide basis also supports this conclusion
12

NOX-limited Versus VOC-limited Ozone Formation

Two major classes of directly emitted precursors drive ozone formation: NOX and VOC. 

Figure 1 shows the relationship of peak ozone concentrations plotted as a function of 

VOC and NOX emission rates.

This simplified illustration shows that two distinct regimes exist with different ozone –

NOX – VOC sensitivity. In the NOX-limited regime (with relatively low NOX and high 

VOC), ozone increases with increasing NOX and changes little in response to increasing 

VOC. The NOX-saturated or VOC-limited regime has ozone decreases with increasing 

NOX and ozone increases with increasing VOC. The dotted line represents a local 

maximum for ozone versus NOX and VOC, separating the NOX-limited and VOC-limited 

regimes.

Figure 1: Peak Ozone Concentrations as a Function of VOC and NOX Emission 

Rates

Studies in recent years have examined the sensitivity of surface ozone formation to 

precursor species concentrations of VOC and NOX. (See, for example, B. Duncan et 

al., "The sensitivity of U.S. surface ozone formation to NOX and VOCs as viewed from 

space," presented at the eighth annual CMAS conference, Chapel Hill, NC, October 19-

21, 2009.) These studies have invariably concluded that peak ozone concentrations are 

more sensitive to NOX emissions over most of the United States. This conclusion is due 

in part to substantial decreases in NOX emissions, primarily from stationary sources and 

particularly over the last two decades, which have lead to an additional reduction in the 

NOX-VOC emissions ratio. Another factor is that peak summertime ozone formation is 

more sensitive to changes in NOX with increasing temperature because emissions of 

highly reactive, biogenic isoprene increase with temperature and thus increase the total 
13

VOC emissions available for reaction. Very few exceptions exist to this rule; only a few 

urban core areas such as Chicago and New York City have historically shown 

reductions in ozone due to the implementation of VOC emissions control measures.

The Georgia Institute of Technology (Georgia Tech) conducted a series of emissions 

sensitivities in 2009 as part of the Association for Southeastern Integrated Planning 

(ASIP) project. Attachment B provides a presentation summarizing the results of the 

study. The study examined the impact of NOX and VOC emission reductions on 8-hour 

ozone concentrations using CMAQ model simulations for a summer ozone episode 

(June 1 – July 10, 2002). Figures 2 through 4 present certain results of the study as 

they pertain to Virginia. One of the sensitivity runs examined the effects of a 30% 

reduction in domain-wide anthropogenic VOCs on ozone formation. The impacts were 

then normalized by emissions. Figure 2 summarizes the results for Virginia. 

A second sensitivity run examined the effects of a 30% reduction in ground level NOX

for jurisdictions within Virginia on ozone formation. The impacts were then normalized 

by emissions. Figure 3 summarizes the results of the receptor locations in Virginia. 

The model response to ground level NOX reductions was two orders of magnitude (i.e., 

more than 100 times) greater than the response from anthropogenic VOC reductions. 

Figure 2: Ozone Response to Reductions in Anthropogenic VOC 
14

Similarly, a third sensitivity run examined the effects of a 30% reduction in Virginia point 

source NOX on ozone formation. The impacts were again normalized by emissions. 

Figure 4 provides a summary of these results.

Figure 3: Ozone Response to Reductions in Ground Level NOX

Figure 4: Ozone Response to Reductions in Point Source NOX
15

The model response to point source NOX reductions was two to three orders of 

magnitude (i.e., more than 100-1,000 times) greater than the response from 

anthropogenic VOC reductions. The model response for this sensitivity was more 

variable and dependent on the location of the point source relative to the receptor 

locations as compared to the sensitivity run for ground level NOX. These sensitivities 

demonstrate that NOX reductions are more efficacious than VOC reductions for 

improvement in ozone air quality in the Commonwealth.

Stage II VRS Benefits for Ozone Air Quality

These model results can be used to quantify the benefits of the Stage II control 

requirements. Table 6 provides a summary of the estimated ozone air quality benefits 

of the Stage II program during peak summertime O3 conditions with no consideration for 

incompatibility excess emissions.

+1.24E-05

The results in Table 6 show that the ozone benefits resulting from the Stage II program 

emission reductions, excluding the incompatibility excess emissions, are very small. In 

the Richmond-Petersburg area, the model predicted a slight increase in ozone 

concentrations (i.e., a disbenefit). These data demonstrate that the existence of the 

Stage II program has little or no effect on ozone levels.

Contribution to Emissions Inventory

Stage II VRS requirements may also be evaluated based on its contribution to the VOC 

emissions inventory in context of regional air quality modeling. Such modeling accounts 

for impacts from both anthropogenic and biogenic VOC emission sources, and biogenic 

VOC sources often have quite sizeable emissions as compared to anthropogenic 

emissions sources. Table 7 summarizes the contributions to both regional and 

statewide emission inventories, exclusive of incompatibility excess emissions. 

Emissions within this table include emissions from both biogenic sources and 

anthropogenic sources of VOC.

Table 7 illustrates that the Stage II program represents a very small fraction of the total 

regional and state inventories and that there is an abundance of both anthropogenic 

and biogenic VOC emissions present in the atmosphere. This lends further support to 

the air quality modeling results that reveal peak ozone in this area of Virginia is 

unaffected by relatively small changes in VOC emissions.

Conclusion

Based on current and projected emissions, it is clear that Stage II is no longer needed 

to maintain ozone air quality in the Virginia OTR jurisdictions, and Stage II VRS should 

be removed from the Virginia SIP.

AIR POLLUTION CONTROL BOARD

Proposed State Implementation Plan Revision -

Stage II Vapor Recovery Systems in Northern 

Virginia

Notice of action: The Department of Environmental Quality 

(DEQ) is announcing an opportunity for public comment on a 

proposed plan to attain and maintain the national ambient air 

quality standard (NAAQS) for ozone in the Northern Virginia 

portion of the Metropolitan Washington, D.C. Ozone 

Nonattainment Area. The Commonwealth intends to submit 

the plan as a revision to the Commonwealth of Virginia State 

Implementation Plan (SIP) in accordance with the 

requirements of § 110(a) of the federal Clean Air Act (CAA). 

The SIP is the plan developed by the Commonwealth in order 

to fulfill its responsibilities under the CAA to attain and 

maintain the ambient air quality standards promulgated by the 

U.S. Environmental Protection Agency (EPA).

Purpose of notice: DEQ is seeking comments on the overall 

plan and on the issue of whether the plan will enable the 

Northern Virginia area to continue to meet obligations under 

the CAA.

Public comment period: February 10, 2014, to March 14, 

2014.

Public hearing: A public hearing will be conducted on March 

10, 2014, in Conference Room 1, Department of 

Environmental Quality, 13901 Crown Court, Woodbridge, 

Virginia at 11 a.m. Directions may be found at 

http://www.deq.virginia.gov/Locations/NorthernRegionalOffi

ce.aspx.

Description of proposal: The purpose of this SIP revision is to 

amend the ozone attainment and maintenance plans for the 

portions of Virginia that are part of the Ozone Transport 

Region (OTR) such that Stage II vapor recovery systems 

(VRS) are no longer required after December 31, 2013. Since 

the original development of these plans, EPA has determined 

that onboard refueling vapor recovery (ORVR) is in 

widespread use and therefore no longer needed for ozone 

control in OTR localities that can further demonstrate that the

removal of Stage II will not interfere with maintenance of the 

ozone NAAQS. The Commonwealth has determined that 

Stage II is no longer needed in the area's plans and that 

removing this control requirement does not interfere with 

maintenance of any ozone NAAQS.

Localities affected: Counties of Stafford, Arlington, Fairfax, 

Loudoun, and Prince William and Cities of Alexandria, 

Fairfax, Falls Church, Manassas, and Manassas Park.

Federal information: This notice is being given to satisfy the 

public participation requirements of federal regulations (40 

CFR 51.102). The proposal will be submitted as a revision to 

the Commonwealth of Virginia SIP under § 110(a) of the 

CAA in accordance with 40 CFR 51.104. DEQ plans to 

submit all provisions of the proposal as a revision to the 

Commonwealth of Virginia SIP.

How to comment: DEQ accepts written comments by email, 

fax, and postal mail. In order to be considered, comments 

must include the full name, address, and telephone number of 

the person commenting and be received by DEQ by the last 

day of the comment period. All materials received are part of 

the public record.

To review proposal: The proposal and supporting documents 

are available on the DEQ Air Public Notices for Plans 

website: 

http://www.deq.state.va.us/Programs/Air/PublicNotices/airpla

nsandprograms.aspx. The documents may also be obtained by
