# Reference: Northern Virginia Ozone 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.

1. SIP submittal.
2. Certification of public participation activities.

1 COMMONWEALTH OF VIRGINIA STATE IMPLEMENTATION PLAN REVISION REMOVAL OF STAGE II GASOLINE VAPOR CONTROLS AT GASOLI NE 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 plan s for the portions of Virginia that are part of the Ozone Transport Region (OTR) such that Stage II vapor recovery systems (VRS) are no longe r required beginning on January 1, 2014

. The state implementation plan (SIP) submittals for the 1990 ozone National Ambient Air Quality Standards ( NAAQS ) required the impleme ntation of the Stage II program in the Virginia OTR jurisdictions. L ater submittals quantified the benefits of this program, which was fully implemented by th ose 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 ne cessary for ozone control purposes and has determined that Stage II is no longer needed in the area's plans , which are approved into the Virgi nia S IP at 40 CFR 52.2420(e). Removing th i s control requirement do es not interfere with maintenance of any ozone NAAQS. EPA guidance suggests that after December 31, 201 3 , incompatibility excess emissions resulting from the use of certain Stage II VRS th at are not compatible with vehicles equipped with ORVR offset emission reductions from Stage II controls. V olatile organic compound (V OC ) 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 (NO X 

# ) ar e 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 re covery 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 tha t the incremental emissions control achieved by S t age II VRS beyond ORVR is less than 10% of the area

- wide emissions inve ntory associated with refueling highway motor vehicles. In fact, this analysis, which is based on EPA’s guidance, shows that incompati bility 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 b a sed 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 emerg ing 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 refu eling 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 t wo 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 hel p move the vapors out of the vehicle tank and in to 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 re cover 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 re turned to the tank against the volume of liquid dispensed. The larger the design A/L ratio, the greater the amo unt 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 t he 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 te chnology. 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. Federa l 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 a n ORVR

- vehicle with a vacuum assist

- type Stage II equipped dispenser, compatibility problems may result in an increase in e missions 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 func tion 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 determine s wh en an ORVR vehicle is being refueled and reduce s the A/L ratio to avoid compatibility emission effects

.

Im plementation of Stage II in the Virginia Jurisdictions Included in the OTR
Under the 1990 1

- hour ozone NAAQS of 0.12 p arts per million (p pm ) or 124 parts per billion (ppb), EPA originally des i gnated the OTR jurisdictions in Virginia a s a serious nonattainment area on November 6, 1991 (56 FR 56694). These localities included the counties of Stafford, Arlington, Fairfax, Loudoun, and Prince Wil liam, 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) , t he area submit ted 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 det ermination of attainment for the 1990 ozone NAAQS for the area on July 25, 2008 (73 FR 43360). EPA revoked the 199 0 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 Fr edericksburg 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 submit ted 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 P rince 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 Ju ne 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 implem entation 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 o zone NAAQS, with a classification of marginal. The Virginia portion of the Washington DC

MD

- 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, Mana ssas 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 199 0 ozone NAAQS under § 182(b)(3): (A) Gasoline Vapor Recovery.

— General Rule.

— Not later than 2 y ears 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 di spensing systems to install and operate, b y 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, E PA 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 o ccurred, 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 f or 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 o n 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 loc ated 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. No t 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 199 0 and 1997 ozone no nattainment areas, as well as the maintenance plan for the Fredericksburg 1997 ozone maintenance area, contain Stage II VRS emission reduction benefits

. The 199 0 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 fr o m the implemented control program

. Th e 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 emission s resulting from the implementation of both Stage II VRS and ORVR, removing State II control requirements after Decemb er 31 , 201 3 , 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 wi th 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 Liqu id Storage and Transfer Operations, of Part II of 9VAC5

- 40 (Existing Stationary Sources).
To re mov e Stage II control requirements from the Virginia SIP pertinent to the Virginia OTR jurisdictions , this submittal demonstrates compliance with the noninterfe rence 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 pla n 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 § 1 84(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 th an 10% of the area

- wide emissions inventory associated with refueling highway motor vehicles. These estimates are area

specific 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 technolog y phases into the fleet. For this effort, the Virginia Department of Motor Vehicles (DMV) supplied vehicle population data including vehicle mix and fleet age informati on for each jurisdiction

. The Virginia Department of Transportation (VDOT) supplied ve hicle 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 guidanc e. 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). A ttachment A provides t he 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, o r 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 A ttachment 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 (7 7

. 6 %), the percentage of VMT by ORVR

equipped vehicles (7 9.3 %), and the amount of gasoline dispensed into ORVR

- equipped vehicles (7 7 .3%) exceeded 75% by the end of 20 11 , 200 9 , and 20 09 respectively. Using the latest year for the benchmark of widespread use, which is vehicle population percentage, the area achieved widespread use in year 201 1

. Table 1 : Widespread Use Analysis Calculation Basis Year Percentage Vehicle Population Percentage 201 1 7 7.6 % VMT Percentage 200 9 7 9.3 % Gasoline Dispensed Percentage 20 09 7 7 .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 Inv entory 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 percenta ge by the end of calendar year 200 8 (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 requirement s. When an area’s increment calculations show that the emission control achieved by S tage II VRS beyond that achieved by ORVR is less than 10%, EPA ’ s guidance s tates that the area satisfies comparability requirements. EPA’s guidance notes that the numb er 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 fro m 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 reduct ions, 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 b y 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 va riable definitions:
Increment i 

# = (Q SII 

# )(1

- Q ORVR i 

# )(η iuSII 

# )

- (Q SIIva 

# )(CF i 

# ) Q SII 

# 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. Q ORVR i 

# This variable represents the fraction of gasoline dispensed to ORVR

equipped 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.
η iuSII 

# This variable represents the Stage II control efficiency, which for these jurisdict i ons is 77%.

# 9 Q SIIva 

# This variable represents the fraction of gasoline dispensed by vacuum assist Stage II systems. EPA’s guidan ce document provides regional data for this variable in Table A

- 6. CF i 

# 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 f raction 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 eq uations 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 3 provides the summary of the incremental calculations assuming a 56% control efficiency in th is 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, 201 2

T hese 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, 201 3 , 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 cal culations 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 E missions EPA’s guidance offers two methodologies for evaluating t he 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:
Tons i 

# = ( Increment i 

# )(GC i 

# )(EF)
GC i 

# This vari able 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 gr ams 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 appl ied to the Virginia OTR jurisdictions. By December 31, 2013 , this equation shows that incompatibility excess emissions overwhelm Stage II VRS benefits by 0.0 1 tons/day of VOC.

# 11 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 em issions inventory from the continued implementation of the Stage II VRS program

. Table 5 summarizes the results of the calculations detailed in A ttachment 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 " column s in Table 5. Attachment A provides the details of these calculations in the worksheet entitled, "NoVA

- Excess Emissions."

- 0.544 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 significa ntly 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 NO X 

# - limited V ersus VOC

- limited Ozone Formation Two major classes of directly emitted precursors drive ozone formation: NO X 

# and VOC. Figure 1 shows the relationship of peak ozone concentrations plotted as a function of VOC and NO X 

# emission rates. This simplified illustration shows that two distinct regimes exist with different ozone

– NO X 

# – VOC sensitivity . In the NO X 

# - limited regime (with relatively low NO X 

# and high VOC), ozone increases with increasing NO X 

# and changes little in response to increasing VOC. The NO X 

# - saturated or VOC

- limited regime has ozone decreases with increasing NO X 

# and ozone increases with increasing VOC. The dotted line represents a local maximum for ozone versus NO X 

# and VOC, separating the NO X 

# - limited and VOC

- limited regimes.

Figure 1 : Peak Ozone Concentrations as a Function of VOC and NO X 

# Emission Rates Studies in recent years have examined the sensitivity of surface ozone formation to precursor species concentrations of VOC and NO X 

# . (See, for example, B. Duncan et al., "The sensitivity of U.S. surface ozone formation to NO X 

# 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 NO X 

# emissions over most of the United States. This conclusion is due in part to substantial decreases in NO X 

# emissions, primarily from stationary sources and particularly over the last two decades, which have lead to an additional reduction in the NO X 

# - VOC emissions ratio. Another factor is that peak summertime ozone formatio n is more sensitive to changes in NO X 

# 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; o nly 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 sensit ivities 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 NO X 

# and VOC emission reductions on 8

- hour ozone con centrations 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 NO X 

# for jurisdictions within Virginia on ozone formation. The impacts were then normalized by e missions. Figure 3 summarizes the results of the receptor locations in Virginia. The model response to ground level NO X 

# 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 NO X 

# on ozone formation. The impacts were again normalized by emiss ions. Figure 4 provides a summary of these results. Figure 3 : Ozone Response to Reductions in Ground Level NO X



# Figure 4 : Ozone Response to Reductions in Point Source NO X

# 15 The model response to point source NO X 

# 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 rel ative to the receptor locations as compared to the sensitivity run for ground level NO X 

# . These sensitivities demonstrate that NO X 

# reductions are more efficacious than VOC reductions for improvement in ozone air quality in the Commonwealth. Stage II VRS B enefits 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 O 3 

# conditions with no consideration for incompatibility excess emissions.

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). Th ese 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 source s 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 inc lude 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.

Volume 30, Issue 12 Virginia Register of Regulations February 10, 2014 1700 GENERAL NOTICES/ERRATA 

# 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 announcin g 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 inten ds 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 it s 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 wil l enable the N orthern 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 Enviro nmental 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 N AAQS. 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 participati on 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 rev ision 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 b y 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 contacting the DEQ representative named below.
