EXECUTIVE SUMMARY
MAG 2014 STATE IMPLEMENTATION PLAN REVISION

FOR THE REMOVAL OF STAGE II VAPOR RECOVERY CONTROLS

EXECUTIVE SUMMARY

The Maricopa Association of Governments has prepared the MAG 2014 State

Implementation Plan Revision for the Removal of Stage II Vapor Recovery Controls in the

Maricopa Eight-Hour Ozone Nonattainment Area through a coordinated effort among the

Arizona Department of Weights and Measures, Arizona Department of Environmental

Quality, and Maricopa County Air Quality Department. On May 16, 2012, the

Environmental Protection Agency (EPA) made a determination that onboard refueling

vapor recovery (ORVR) systems are in widespread use throughout the motor vehicle fleet. 

Since Stage II is a duplicative system, this plan revision requests that EPA remove the

requirement to install and operate Stage II vapor recovery systems in the Maricopa eighthour ozone nonattainment area for new gasoline dispensing facilities beginning in 2014

and for existing gasoline dispensing facilities beginning in October 2016, before a

disbenefit begins to occur in 2018. 

Since September 2012, the Arizona Department of Weights and Measures, Arizona

Department of Environmental Quality, Maricopa County Air Quality Department, and MAG

have been coordinating with the Environmental Protection Agency on various approaches

to remove the Stage II vapor recovery systems based upon the EPA guidance. In a

November 15, 2013, conference call with the Arizona agencies, EPA recommended

following a Stage II removal schedule for new gasoline dispensing facilities beginning in

2014 and existing facilities beginning after the 2016 ozone season (October 2016-

September 2018). A removal schedule that begins after the 2016 ozone season results

in the smallest temporary emission increases of the options considered. EPA requested

that the statutory authority for Stage II removal be included in the plan revision. In addition,

EPA prefers one plan revision for both new and existing facilities.

Section 182(b)(3) of the Clean Air Act, as amended in 1990, requires gasoline dispensing

facilities located in nonattainment areas classified as Serious and above for the ozone

National Ambient Air Quality Standards to operate Stage II vapor recovery systems. Stage

II vapor recovery systems are installed at gasoline dispensing facilities to control emissions

of displaced volatile organic compound (VOC) vapors during the transfer of gasoline from

storage tanks to motor vehicle fuel tanks. The displaced vapors from the vehicle fuel tank

are captured by the Stage II controls and returned to the underground storage tanks at the

gasoline dispensing facility.

Onboard refueling vapor recovery systems consist of an activated carbon canister installed

on the motor vehicle into which displaced volatile organic compound vapors are routed

from the vehicle fuel tank during refueling. When the engine of the motor vehicle is

started, the vapors are purged from the activated carbon canister and into the engine

ES - 1
where they are burned as fuel. Onboard refueling vapor recovery and Stage II are

redundant emission control systems.

In response to the requirements of Section 182(b)(3) of the Clean Air Act, the State of

Arizona passed legislation in 1992 (S.B. 1430) that mandated the implementation of Stage

II vapor recovery controls in ozone nonattainment areas classified as Moderate or above. 

The legislation was incorporated into law as Arizona Revised Statute Title 41, Chapter 15,

Article 7. Under this law, most gasoline dispensing facilities were required to implement

Stage II vapor recovery by November 15, 1993, with all facilities required to implement

Stage II by November 15, 1994.

The Arizona Department of Environmental Quality (ADEQ) originally submitted the

statutory provisions and rules establishing Stage II controls in the Maricopa County onehour ozone nonattainment area in February 1993. In May 1994, ADEQ submitted

amended Stage II vapor recovery rules which EPA approved into the Arizona State

Implementation Plan on November 1, 1994. The latest version of the statutory provisions

and rules regarding Stage II controls in the Maricopa area were approved into the Arizona

State Implementation Plan by EPA in a final rule published on June 13, 2012.

On April 16, 2014, the Arizona State Legislature passed House Bill 2128 which authorized

the removal of Stage II controls in the Maricopa eight-hour ozone nonattainment area for

new gasoline dispensing facilities beginning in 2014 and for existing gasoline dispensing

facilities beginning in October 2016, but no later than September 30, 2018, upon approval

of this revision by EPA. House Bill 2128 contains an emergency clause which allows the

bill to become effective immediately when signed by the Governor. The Governor signed

House Bill 2128 on April 22, 2014. House Bill 2128 also maintains the existing

requirements associated with installing and operating Stage I vapor recovery systems and

clarifies that annual tests are required for Stage I vapor recovery systems. The Arizona

Revised Statutes that authorize the scheduled removal of Stage II controls and maintain

and clarify existing Stage I vapor recovery systems requirements are listed in Table ES-1. 

The Arizona Revised Statutes listed in Table ES-1 are included in Appendix A, Exhibit 2.

On August 7, 2012, the EPA released Guidance on Removing Stage II Gasoline Vapor

Control Programs from State Implementation Plans and Assessing Comparable Measures. 

The EPA guidance provides technical and policy recommendations on how to develop and

submit approvable State Implementation Plan revisions that remove the requirement to

implement Stage II controls. This guidance provides equations that are used to estimate

the areawide impact of Stage II controls on vehicle refueling emissions. 

When assessing the emission reduction benefits associated with Stage II controls on

vehicle refueling emissions, the EPA guidance recommends the use of an equation that

calculates the areawide incremental emission control gain from Stage II controls as

onboard refueling vapor recovery systems are phased in over time. In addition to

calculating the incremental benefits of Stage II controls over time, the guidance also

provides an equation for calculating the areawide volatile organic compound emission

facilities will be complete by September 30, 2018.

reductions associated with the use of Stage II controls as onboard refueling vapor recovery

systems are phased in. The EPA equations indicate that Stage II controls no longer

provide areawide volatile organic compound emission reductions in the Maricopa area

beginning in 2018. A summary of the areawide emission reduction benefits and disbenefits

of Stage II controls along with the percent distribution of onboard refueling vapor recovery

in the gasoline-powered highway vehicle fleet is shown in Table ES-2.

The requested schedule for removal of Stage II controls in the Maricopa eight-hour ozone

nonattainment area in this State Implementation Plan revision includes removing the

requirement to install and operate Stage II controls at new gasoline dispensing facilities

beginning in 2014 and a two-year phased removal of Stage II controls at existing gasoline

dispensing facilities beginning in October 2016 and ending no later than September 30,

2018. Removal of Stage II controls under the schedule requested in this revision optimally

minimizes the temporary areawide increase in volatile organic compound emissions in the

Maricopa area. The temporary increases from new and existing gasoline dispensing

facilities are summed in Table ES-3 to provide the total emission increases associated with

the scheduled removal of Stage II controls in the Maricopa eight-hour ozone nonattainment

area in calendar years 2014 through 2018.

Section 110(l) of the Clean Air Act precludes the EPA from approving a State

Implementation Plan revision if it would interfere with attainment of the National Ambient

Air Quality Standards, reasonable further progress towards attainment, or any other

applicable requirement under the Clean Air Act. Two analyses are performed in this

revision to demonstrate that the loss of temporary emission reduction benefits resulting

from the scheduled removal of Stage II controls in the Maricopa eight-hour ozone

nonattainment area will not interfere with attainment of the ozone National Ambient Air

Quality Standards, or reasonable further progress toward attainment, as required by Clean

Air Act Section 110(l).

The first analysis is consistent with EPA guidance by following a planned phase-out of

Stage II controls in the Maricopa area that optimally minimizes both the temporary volatile

organic compound emissions increase from the loss of Stage II emission reduction benefits

in 2014 through 2017 and the Stage II emissions disbenefit that begins in 2018. EPA’s

guidance on removing Stage II control programs states the following,

“Under the circumstances created by the CAA’s widespread use waiver, a planned

Stage II phase-out that is shown to result in an area-wide VOC emissions increase

may also be consistent with the conditions of CAA section 110(l). A phase-out plan

that would result in very small foregone emissions reductions in the near term that

continue to diminish rapidly over time as ORVR phase-in continues, may result in

temporary increases that are too small to interfere with attainment or progress

towards attainment.” (p. 5)

The temporary emission increases associated with the scheduled removal of Stage II

controls represent less than 0.05% of ozone season day mobile source (onroad and

nonroad) volatile organic compound emissions in years 2014 through 2018. Compared

against the entire volatile organic compound emissions inventory, the temporary emission

increases from removal of Stage II controls represent an even smaller percentage. As

suggested by EPA guidance, temporary emission increases of this size are too small to

interfere with attainment, or progress towards attainment, in the Maricopa eight-hour ozone

nonattainment area. 

The second analysis demonstrates that removal of Stage II controls in the Maricopa eighthour ozone nonattainment area beginning in 2014 still produces a downward trend in future

year mobile source volatile organic compound emissions. For this analysis, EPA’s

NONROAD2008a and MOVES2010b models are used to generate daily ozone season

nonroad and onroad volatile organic compound emissions in the Maricopa area for the

calendar years of 2013 through 2020. The model runs are structured to calculate

emissions without the benefit of Stage II controls. 

Table ES-4 includes the resulting emissions from the model runs and the emission

reduction benefits of Stage II controls. Subtracting the emission reduction benefits of

Stage II controls from the mobile source emissions modeled without Stage II controls

results in total mobile source emissions with Stage II controls in the Maricopa area for

calendar years 2013 through 2020.

Figure ES-1 displays the values in Table ES-4 through trend lines of total mobile source

emissions with and without Stage II emissions in years 2013 through 2020 in the Maricopa

area. Table ES-4 and Figure ES-1 demonstrate that even when the emission reduction

benefits of Stage II controls are removed from total mobile source emissions beginning in

2014, total daily ozone season mobile source volatile organic compound emissions in the

Maricopa area are reduced each year after 2013, continuing their downward trend.

The two analyses described above adequately demonstrate that the scheduled removal

of Stage II controls in the Maricopa eight-hour ozone nonattainment area comply with the

requirements of Section 110(l) of the Clean Air Act. The initial analysis demonstrates that

the increased emissions from the removal of Stage II controls in years 2014 through 2018

are optimally minimized through decommissioning of existing facilities beginning in October

2016 and ending in September 2018. The resulting temporary emission increases are tiny

and too small to interfere with attainment, or progress toward attainment, as suggested by

EPA guidance.

The second analysis illustrates that the removal of Stage II controls in the Maricopa eighthour ozone nonattainment area does not interfere with the downward trend in total mobile

source emissions. Both analyses ensure that the scheduled removal of Stage II controls

in the Maricopa eight-hour ozone nonattainment area will not interfere with attainment of

the ozone National Ambient Air Quality Standard, or reasonable further progress towards

attainment, as required by Section 110(l) of the Clean Air Act.

CHAPTER ONE

INTRODUCTION

The Maricopa Association of Governments has prepared the MAG 2014 State

Implementation Plan Revision for the Removal of Stage II Vapor Recovery Controls in the

Maricopa Eight-Hour Ozone Nonattainment Area through a coordinated effort among the

Arizona Department of Weights and Measures, Arizona Department of Environmental

Quality, and Maricopa County Air Quality Department. On May 16, 2012, the

Environmental Protection Agency (EPA) made a determination that onboard refueling

vapor recovery (ORVR) systems are in widespread use throughout the motor vehicle fleet. 

Since Stage II is a duplicative system, this plan revision requests that EPA remove the

requirement to install and operate Stage II vapor recovery systems in the Maricopa eighthour ozone nonattainment area for new gasoline dispensing facilities beginning in 2014

and for existing gasoline dispensing facilities beginning in October 2016, before a

disbenefit begins to occur in 2018. 

Section 182(b)(3) of the Clean Air Act, as amended in 1990, requires gasoline dispensing

facilities located in nonattainment areas classified as Serious and above for the ozone

National Ambient Air Quality Standards to operate Stage II vapor recovery systems. Stage

II vapor recovery systems are installed at gasoline dispensing facilities to control emissions

of displaced volatile organic compound vapors during the transfer of gasoline from storage

tanks to motor vehicle fuel tanks. The displaced vapors from the vehicle fuel tank are

captured by the Stage II controls and returned to the underground storage tanks at the

gasoline dispensing facility. 

In addition to the Stage II controls required in Section 182(b)(3), Clean Air Act Section

202(a)(6) requires another method of controlling emissions from vehicle refueling referred

to as onboard refueling vapor recovery systems. Onboard refueling vapor recovery

systems consist of an activated carbon canister installed on the motor vehicle into which

displaced volatile organic compound vapors are routed from the vehicle fuel tank during

refueling. When the engine of the motor vehicle is started, the vapors are purged from the

activated carbon canister and into the engine where they are burned as fuel. 

Beginning with motor vehicles manufactured in 1998, onboard refueling vapor recovery

systems have been phased in, and are a required control on nearly all new highway

vehicles manufactured since 2006. Due to turnover in the motor vehicle fleet, older

vehicles without onboard refueling vapor recovery systems will continue to be replaced by

vehicles equipped with onboard refueling vapor recovery systems. 

Onboard refueling vapor recovery and Stage II are redundant emission control systems. 

Section 202(a)(6) of the Clean Air Act provides authority for the EPA to waive the Stage

II requirements of Section 182(b)(3) after the EPA Administrator determines onboard

refueling vapor recovery systems are in widespread use.

1 - 1
On May 16, 2012, the EPA published a final rule determining that onboard refueling vapor

recovery systems are in widespread use throughout the motor vehicle fleet. By this final

rule, EPA exercised the authority provided in Section 202(a)(6) of the Clean Air Act to

waive the requirement in Section 182(b)(3) for states to implement Stage II vapor recovery

systems at gasoline dispensing facilities in nonattainment areas classified as Serious and

above for the ozone National Ambient Air Quality Standards. This in turn allows states that

were required to implement Stage II vapor recovery systems under Section 182(b)(3) of

the Clean Air Act the option to submit to the EPA revised ozone State Implementation

Plans that remove Stage II controls. 

Since September 2012, the Arizona Department of Weights and Measures, Arizona

Department of Environmental Quality, Maricopa County Air Quality Department, and MAG

have been coordinating with the Environmental Protection Agency on various approaches

to remove the Stage II vapor recovery systems based upon the EPA guidance. In a

November 15, 2013, conference call with the Arizona agencies, EPA recommended

following a Stage II removal schedule for new gasoline dispensing facilities beginning in

2014 and existing facilities beginning after the 2016 ozone season (October 2016-

September 2018). A removal schedule that begins after the 2016 ozone season results

in the smallest temporary emission increases of the options considered. EPA requested

that the statutory authority for Stage II removal be included in the plan revision. In addition,

EPA prefers one plan revision for both new and existing facilities.

BACKGROUND

As mentioned above, Section 182(b)(3) of the Clean Air Act, as amended in 1990, requires

gasoline dispensing facilities located in nonattainment areas classified as Serious and

above for the ozone National Ambient Air Quality Standards to operate Stage II vapor

recovery systems. Originally, Section 182(b)(3) requirements for Stage II controls also

applied to Moderate ozone nonattainment areas. However, Section 202(a)(6) of the Clean

Air Act removed the requirement for Stage II controls in Moderate ozone nonattainment

areas after EPA promulgated onboard refueling vapor recovery standards in April 1994. 

In November 1991, the EPA classified a portion of Maricopa County as a Moderate

nonattainment area for the one-hour ozone National Ambient Air Quality Standard. The

nonattainment area was reclassified to Serious on November 6, 1997, due to failure to

attain the one-hour ozone standard by November 15, 1996.

In response to the requirements of Section 182(b)(3) of the Clean Air Act, the State of

Arizona passed legislation in 1992 (S.B. 1430) that mandated the implementation of Stage

II vapor recovery controls in ozone nonattainment areas classified as Moderate or above. 

The legislation was incorporated into law as Arizona Revised Statute Title 41, Chapter 15,

Article 7. Under this law, most gasoline dispensing facilities were required to implement

Stage II vapor recovery by November 15, 1993, with all facilities required to implement

Stage II by November 15, 1994.

1 - 2
The Arizona Department of Environmental Quality (ADEQ) originally submitted the

statutory provisions and rules establishing Stage II controls in the Maricopa County onehour ozone nonattainment area in February 1993. In May 1994, ADEQ submitted

amended Stage II vapor recovery rules which EPA approved into the Arizona State

Implementation Plan on November 1, 1994. The latest version of the statutory provisions

and rules regarding Stage II controls in the Maricopa nonattainment area were approved

into the Arizona State Implementation Plan by EPA in a final rule published on June 13,

2012.

In April 2004, the EPA classified the Maricopa area as a “Basic” nonattainment area for the

1997 eight-hour ozone standard under Part D, Subpart 1, of the Clean Air Act. The

nonattainment area for the 1997 eight-hour ozone standard included a larger portion of

Maricopa County than the prior one-hour ozone nonattainment area and also included a

small portion of Pinal County located in Apache Junction. Under the anti-backsliding

provision’s of EPA’s rules governing the transition from the one-hour ozone standard to the

eight-hour ozone standard, the Maricopa area remains subject to the requirements of

Section 182(b)(3) of the Clean Air Act due to its classification as Serious for the one-hour

ozone standard on the effective date of the area’s designation as nonattainment for the

1997 eight-hour ozone standard (June 15, 2004).

On June 14, 2005, EPA approved the One-Hour Ozone Redesignation Request and

Maintenance Plan for the Maricopa County nonattainment area. The EPA revoked the

one-hour ozone standard on June 15, 2005, which was less stringent than the eight-hour

ozone standard promulgated in 1997.

On May 14, 2012, EPA reclassified the Maricopa area as a Marginal nonattainment area

under Part D, Subpart 2, of the Clean Air Act for the 1997 eight-hour ozone standard. The

Eight-Hour Ozone Plan for the Maricopa Nonattainment Area was approved by EPA on

June 13, 2012. 

The EPA published a final rule on May 21, 2012, which classified the Maricopa area as a

Marginal nonattainment area for the 2008 eight-hour ozone standard and established an

attainment date of December 31, 2015. The nonattainment area for the 2008 eight-hour

ozone standard was expanded slightly to the south and west in Maricopa County as

compared to the boundary established for the 1997 eight-hour ozone standard. A map of

the Maricopa nonattainment area for the 2008 eight-hour ozone standard is shown in

Figure 1-1.

REMOVAL OF STAGE II VAPOR RECOVERY CONTROLS IN THE MARICOPA EIGHTHOUR OZONE NONATTAINMENT AREA

In response to the determination issued by the EPA that onboard refueling vapor recovery

systems are in widespread use throughout the motor vehicle fleet effective May 16, 2012,

this revision to the Arizona State Implementation Plan is requesting removal of the

requirement to install and operate Stage II controls in the Maricopa eight-hour ozone 

1 - 3
1 - 4
nonattainment area for new gasoline dispensing facilities beginning in 2014 and for existing

gasoline dispensing facilities beginning in October 2016, with all facilities having Stage II

controls removed no later than September 30, 2018. This revision is effective upon

approval by EPA.

On April 16, 2014, the Arizona State Legislature passed House Bill 2128 which authorized

the removal of Stage II controls in the Maricopa eight-hour ozone nonattainment area for

new gasoline dispensing facilities beginning in 2014 and for existing gasoline dispensing

facilities beginning in October 2016, but no later than September 30, 2018, upon approval

of this revision by EPA. House Bill 2128 contains an emergency clause which allows the

bill to become effective immediately when signed by the Governor. The Governor signed

House Bill 2128 on April 22, 2014. House Bill 2128 also maintains the existing

requirements associated with installing and operating Stage I vapor recovery systems and

clarifies that annual tests are required for Stage I vapor recovery systems. The Arizona

Revised Statutes that authorize the scheduled removal of Stage II controls and maintain

and clarify existing Stage I vapor recovery systems requirements are listed in Table 1-1. 

The Arizona Revised Statutes listed in Table 1-1 are included in Appendix A, Exhibit 2.

CHAPTER TWO

AREAWIDE IMPACTS OF STAGE II VAPOR RECOVERY CONTROLS

ON VEHICLE REFUELING EMISSIONS

On August 7, 2012, the Environmental Protection Agency (EPA) released Guidance on

Removing Stage II Gasoline Vapor Control Programs from State Implementation Plans and

Assessing Comparable Measures. The EPA guidance provides technical and policy

recommendations on how to develop and submit approvable State Implementation Plan

revisions that remove the requirement to implement Stage II controls. This Chapter uses

the equations recommended by EPA in the 2012 guidance to calculate the areawide

emission reduction benefits associated with Stage II controls on vehicle refueling emissions

in the Maricopa eight-hour ozone nonattainment area. The temporary areawide increase

in emissions associated with the phased removal of Stage II controls in the Maricopa eighthour ozone nonattainment area is also calculated in this Chapter.

EPA GUIDANCE EQUATIONS

When assessing the emission reduction benefits associated with Stage II controls on

vehicle refueling emissions, the EPA guidance recommends the use of an equation that

calculates the areawide incremental emission control gain from Stage II controls as

onboard refueling vapor recovery (ORVR) systems are phased in over time. The EPA

guidance equation calculating the incremental value of Stage II controls is represented by

the following formula:

Incrementi

 = (QSII)(1-QORVRi

)(çiuSII) - (QSIIva

)(CFi

)

Where:

• Incrementiis the incremental areawide emission reduction benefit of Stage

II controls in year i;

• QSII is the fraction of gasoline throughput covered by Stage II controls;

• QORVRiis the fraction of annual gallons of gasoline dispensed to onboard

refueling vapor recovery-equipped vehicles for year i;

• çiuSII is the Stage II controls in-use control efficiency;

• QSIIvais the fraction of gasoline dispensed through vacuum-assisted Stage

II controls; and

• CFi

is the compatibility factor for the increase in underground storage tank

vent emissions over the normal breathing/emptying loss emissions

associated with vacuum-assisted Stage II controls for year i.

The incremental value calculated by the EPA guidance equation identifies the areawide

emission reduction benefits of Stage II controls relative to the distribution of onboard

refueling vapor recovery systems in a given year. If the incremental value is greater than

2 - 1
zero, then Stage II controls provide areawide emission reduction benefits. If the

incremental value is negative, then Stage II controls no longer provide areawide emission

reduction benefits and actually produce an areawide emission disbenefit due to

incompatibility issues between vehicles equipped with onboard refueling vapor recovery

systems and gasoline dispensing facilities equipped with vacuum-assisted Stage II

controls.

Table 2-1 shows the calculated incremental value of Stage II controls for years 2013

through 2020 for the Maricopa area. The Table identifies that Stage II controls no longer

provide areawide emission reduction benefits beginning in year 2018 for the Maricopa

area. Additional details regarding the inputs and calculations associated with the EPA

guidance equation used to produce Table 2-1 are provided in the Technical Support

Document (Appendix A, Exhibit 1). 

In addition to calculating the incremental benefits of Stage II controls over time, the EPA

guidance also provides an equation for calculating the amount of areawide volatile organic

compound (VOC) emission reductions associated with the use of Stage II controls as

onboard refueling vapor recovery systems are phased in. The EPA guidance equation

calculating the amount of volatile organic compound emission reductions associated with

use of Stage II controls is represented by the following formula:

VOCi = (Incrementi)(GCi)(EF)

Where:

• VOCiis the amount of areawide volatile organic compound emission

reductions associated with use of Stage II controls during the ozone season

in year i, in kilograms per day;

• Incrementiis the incremental areawide emission reduction benefit of Stage

II controls in year i;

• GCiis the projected gasoline consumption during the ozone season in year

i, in gallons per day; and

• EF is the uncontrolled displacement refueling emission factor during the

ozone season in grams per gallon.

Table 2-2 shows the calculated areawide volatile organic compound emission reductions

associated with the use of Stage II controls in the Maricopa area during the ozone season

(May - September) for years 2013 through 2020. Table 2-2 displays negative emission

reductions for Stage II controls beginning in year 2018, which is a direct reflection of the

negative incremental value. As in Table 2-1, this indicates that Stage II controls no longer

provide areawide emission reductions in the Maricopa area beginning in 2018. Additional

details regarding the inputs and calculations associated with the EPA guidance equation

used to produce Table 2-2 are provided in the Technical Support Document (Appendix A,

Exhibit 1). A summary of the areawide emission reduction benefits and disbenefits of

Stage II controls along with the percent distribution of onboard refueling vapor recovery in

the gasoline-powered highway vehicle fleet is shown in Table 2-3.

TEMPORARY AREAWIDE INCREASE IN VOLATILE ORGANIC COMPOUND

EMISSIONS UNDER A PHASED REMOVAL OF STAGE II CONTROLS IN THE

MARICOPA EIGHT-HOUR OZONE NONATTAINMENT AREA

The requested schedule for removal of Stage II controls in the Maricopa eight-hour ozone

nonattainment area in this State Implementation Plan revision includes removing the

requirement to install and operate Stage II controls at new gasoline dispensing facilities

beginning in 2014 and a two-year phased removal of Stage II controls at existing gasoline

dispensing facilities beginning in October 2016 and ending no later than September 30,

2018. Removal of Stage II controls under the schedule requested in this revision optimally

minimizes the temporary areawide increase in volatile organic compound emissions in the

Maricopa area. 

New Gasoline Dispensing Facilities

The temporary increase in emissions from the construction of new gasoline dispensing

facilities without Stage II controls occurs in 2014 through 2017, since Stage II controls no

longer provide areawide emission reduction benefits beginning in 2018. Increased

emissions from new facilities are calculated by first quantifying the percent of the total

emission reduction benefits from Stage II controls that new facilities account for in 2014

through 2017. Using data provided by the Arizona Department of Weights and Measures

on the number of new and total gasoline dispensing facilities in the Maricopa area for

calendar years 2008 through 2012, the percent of emission reduction benefits from Stage

II controls that are attributable to new gasoline dispensing facilities for calendar years 2008

through 2012 in the Maricopa area is calculated by dividing the number of new gasoline

dispensing facilities by the total number of gasoline dispensing facilities for each calendar

year. Table 2-4 lists the percent of Stage II emission reduction benefits associated with

new gasoline dispensing facilities in the Maricopa area for calendar years 2008 through

2012. The average percent of emission reduction benefits associated with new gasoline

dispensing facilities in calendar years 2008 through 2012 is 2.06% as shown in Table 2-4.

The average percent of emissions reduction benefits associated with new facilities is next

used to calculate the temporary increase in emissions for new facilities for calendar years

2014 through 2017 in the Maricopa area by multiplying the average percent shown in Table

2-4 (2.06%) by the total emission reduction benefits from Stage II controls in 2014 through

2017 as previously calculated and listed in Table 2-2. This calculation results in a

temporary increase of 15 kilograms of volatile organic compound emissions per ozone

season day in 2014 (e.g., 2.06% x 725 kg/day), ten kilograms per ozone season day in

2015, five kilograms per ozone season day in 2016, and one kilogram per ozone season

day in 2017. Table 2-5 lists the temporary increase in emissions from new gasoline

dispensing facilities constructed in 2014 through 2017 without Stage II controls in the

Maricopa area.

Existing Gasoline Dispensing Facilities

In order to optimally minimize the temporary increase in emissions from removal of Stage

II controls at existing gasoline dispensing facilities and allow for adequate time to safely

decommission equipment, the removal of Stage II controls at existing facilities in the

Maricopa area are phased in over a two-year period beginning after the end of the 2016

ozone season (October 2016 through September 2018). The Arizona Department of

Weights and Measures anticipates that the decommissioning of Stage II controls at existing

facilities will be spread evenly over each of the 24 months in October 2016 through

September 2018. Decommissioning is expected to occur for existing facilities during the

month when the annually scheduled Stage II controls test would have occurred. Since it

will take 24 months to decommission the over 1,000 existing gasoline dispensing facilities

in the Maricopa area, the older half of existing facilities will decommission in the first 12

months of the decommissioning period (October 2016 through September 2017), while the

newer half of existing facilities will decommission in the second 12 months of the

decommissioning period (October 2017 through September 2018).

A small number of existing gasoline dispensing facilities without Stage II controls will exist

in the 2015 and 2016 ozone seasons before the decommissioning period begins as a

result of new facilities built in 2014 and 2015 without Stage II controls (e.g., in 2015, 2.06%

of existing facilities will not have Stage II controls due to the new facilities built in 2014; in

2016, 4.12% of existing facilities will not have Stage II controls due to new facilities built

in 2014 and 2015). Accordingly, the temporary increase in emissions from existing

facilities in 2015 and 2016 is calculated by multiplying the percent of existing facilities

without Stage II controls by the emission reduction benefits of Stage II in 2015 and 2016. 

In order to calculate the temporary increase in emissions from existing facilities in 2017,

the percent of existing gasoline dispensing facilities in 2017 that will have Stage II controls

removed by the end of the ozone season (September 30, 2017) must be calculated. As

explained above, half of the existing gasoline dispensing facilities with Stage II controls will

be decommissioned between October 2016 through September 2017, with

decommissioning scheduled to occur evenly over each month. Under this schedule, 50.0%

of the existing gasoline dispensing facilities will have Stage II controls removed by the end

of the ozone season. Thus, the temporary increase in emissions from existing facilities in

2017 is calculated by multiplying the percent of existing facilities without Stage II controls

by the emission reduction benefits of Stage II in 2017. 

In 2018, areawide emission reduction benefits from Stage II controls no longer occurs in

the Maricopa area; rather, Stage II controls that remain in place during the 2018 ozone

season produce emission increases due to the incompatibility between Stage II controls

and onboard refueling vapor recovery systems. As such, the temporary increase in

emissions during 2018 are from facilities that have yet to decommission Stage II controls

by the beginning of the 2018 ozone season. The 2018 ozone season begins in May 2018. 

Under the phased-in decommissioning schedule requested in this revision, 79.17% of the

existing gasoline dispensing facilities would have removed Stage II controls by May 2018

2 - 9
(i.e., through April 2018, 19 months of the 24 month decommissioning period has passed,

19 ÷ 24 = 79.17%), leaving 20.83% of existing facilities with Stage II controls still in place. 

The temporary increase in emissions from existing facilities in 2018 is therefore calculated

by multiplying the percent of existing facilities with Stage II controls in place at the

beginning of the 2018 ozone season by the areawide emission disbenefit of Stage II

controls in 2018.

In summary, the temporary increase in emissions associated with the removal of Stage II

controls at existing gasoline dispensing facilities in the Maricopa area in 2015 through 2018

is listed in Table 2-6. The temporary increases from new and existing gasoline dispensing

facilities are summed in Table 2-7 to provide the total emission increases associated with

the scheduled removal of Stage II controls in the Maricopa eight-hour ozone nonattainment

area in calendar years 2014 through 2018.

DEMONSTRATION OF COMPLIANCE WITH CLEAN AIR ACT

SECTION 110(l) REQUIREMENTS

Section 110(l) of the Clean Air Act precludes the EPA from approving a State

Implementation Plan revision if it would interfere with attainment of the National Ambient

Air Quality Standards, reasonable further progress towards attainment, or any other

applicable requirement under the Clean Air Act. The analyses provided in this chapter

demonstrate that the scheduled removal of Stage II controls in the Maricopa eight-hour

ozone nonattainment area complies with the requirements of Section 110(l) of the Clean

Air Act. 

CLEAN AIR ACT SECTION 110(l) REQUIREMENTS

Clean Air Act Section 110(l) states the following,

“Each revision to an implementation plan submitted by a State under this chapter

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 7501 of this title), or any other applicable

requirement of this chapter.”

For this revision, complying with Section 110(l) of the Clean Air Act requires an explanation

of how the removal of Stage II controls in the Maricopa eight-hour ozone nonattainment

area does not interfere with attainment of the ozone National Ambient Air Quality Standard

or reasonable further progress towards attainment. EPA’s August 7, 2012 guidance

document, Guidance on Removing Stage II Gasoline Vapor Control Programs from State

Implementation Plans and Assessing Comparable Measures, additionally states,

“In evaluating whether a given SIP revision would interfere with attainment or

maintenance, as required by section 110(l), the EPA generally considers whether

the SIP revision will allow for an increase in actual emissions into the air over what

is allowed under the existing EPA-approved SIP.” (p. 4)

The loss of the temporary emission reduction benefits of Stage II controls under the

scheduled removal requested in this revision represents a temporary increase in emissions

over what is currently projected for gasoline refueling in the EPA-approved Arizona State

Implementation Plan. The following analyses provide demonstrations that the loss of

temporary emission reduction benefits resulting from the scheduled removal of Stage II

controls in the Maricopa eight-hour ozone nonattainment area will not interfere with

attainment of the ozone National Ambient Air Quality Standards, or reasonable further

3 - 1
progress toward attainment, as required by Clean Air Act Section 110(l).

PHASED STAGEII REMOVALSCHEDULETHAT OPTIMALLY MINIMIZESTEMPORARY

VOLATILE ORGANIC COMPOUND EMISSION INCREASES

EPA’s guidance on removing Stage II control programs states the following,

“Under the circumstances created by the CAA’s widespread use waiver, a planned

Stage II phase-out that is shown to result in an area-wide VOC emissions increase

may also be consistent with the conditions of CAA section 110(l). A phase-out plan

that would result in very small foregone emissions reductions in the near term that

continue to diminish rapidly over time as ORVR phase-in continues, may result in

temporary increases that are too small to interfere with attainment or progress

towards attainment.” (p. 5)

In light of this guidance, the planned phase-out of Stage II controls in the Maricopa area

optimally minimizes both the temporary volatile organic compound emissions increase from

the loss of Stage II emission reduction benefits in 2014 through 2017 and the Stage II

emissions disbenefit that begins in 2018. Since there are over 1,000 gasoline dispensing

facilities in the Maricopa area, the Arizona Department of Weights and Measures estimates

that it will take two years to remove Stage II controls at existing facilities in a manner that

allows for proper decommissioning of Stage II controls. The schedule requested in this

revision begins the removal of Stage II controls at existing facilities in October 2016, after

the 2016 ozone season, and ends no later than September 30, 2018. Additionally, the

schedule allows new facilities (approximately 22 facilities per year on average) to construct

without Stage II controls beginning in 2014. Allowing new facilities to construct without

Stage II controls avoids the additional economic burden of having to both install and

remove Stage II controls in the period of a few years. 

By waiting to start the removal of Stage II controls at existing facilities in October 2016, the

emission reduction benefits of Stage II controls are only lost for a single ozone season

(2017), since Stage II controls no longer provide areawide emission reduction benefits

beginning in 2018. The emission reduction benefits of Stage II controls are also the

smallest in 2017 as compared to earlier years, which limits the impacts of removing Stage

II controls (see Table 2-2). Additionally, since the decommissioning process will take two

years to complete, only fifty percent of existing facilities will have Stage II controls removed

by the end of the 2017 ozone season, with the other fifty percent of existing facilities still

receiving the emission reduction benefits of Stage II controls in the 2017 ozone season.

At the start of the 2018 ozone season, almost eighty percent of existing facilities will have

had Stage II controls removed in the Maricopa area under the schedule requested in this

revision (see Table 2-6). As such, only twenty percent of existing facilities (those with

Stage II controls) will experience the emissions disbenefit of Stage II controls during the

2018 ozone season. By the end of the 2018 ozone season all gasoline dispensing facilities

will be operating without Stage II controls in the Maricopa area, ensuring that the increased

3 - 2
emission disbenefit from Stage II controls in following ozone seasons will be avoided.

The temporary emission increases associated with the scheduled removal of Stage II

controls (see Table 2-7) represent less than 0.05% of ozone season day mobile source

(onroad and nonroad) volatile organic compound emissions in years 2014 through 2018. 

Compared against the entire volatile organic compound emissions inventory, the temporary

emission increases from removal of Stage II controls represent an even smaller

percentage. As suggested by EPA guidance, temporary emission increases of this size

are too small to interfere with attainment, or progress towards attainment, in the Maricopa

eight-hour ozone nonattainment area. 

DECLINING TREND IN ONROAD AND NONROAD VOLATILE ORGANIC COMPOUND

EMISSIONS AFTER REMOVAL OF STAGE II VAPOR RECOVERY CONTROLS

This analysis demonstrates that removal of Stage II controls in the Maricopa eight-hour

ozone nonattainment area beginning in 2014 still produce a downward trend in future year

mobile source volatile organic compound emissions. This provides additional evidence

that the removal of Stage II controls will not interfere with attainment of the ozone National

Ambient Air Quality Standard in the Maricopa area, or reasonable further progress towards

attainment, as required by Section 110(l) of the Clean Air Act.

For this analysis, EPA’s NONROAD2008a and MOVES2010b models are used to generate

daily ozone season nonroad and onroad volatile organic compound emissions in the

Maricopa area for the calendar years of 2013 through 2020. The model runs are

structured to calculate emissions without the benefit of Stage II controls. Resulting

emissions from the model runs are presented in Table 3-1. Additional details on the

development of inputs and calculations associated with each of the model runs are

available in the Technical Support Document (Appendix A, Exhibit 1).

Table 3-1 also includes the emission reduction benefits of Stage II controls in the Maricopa

area as calculated per EPA guidance equations in Chapter 2 of this revision (see Table 2-

2). Subtracting the emission reduction benefits of Stage II controls from the summed

onroad and nonroad mobile source emissions modeled without Stage II controls results in

total mobile source emissions with Stage II controls in the Maricopa area for calendar years

2013 through 2020. As can be seen in Table 3-1, even when the emission reduction

benefits of Stage II controls are removed from total mobile source emissions beginning in

2014, total daily ozone season mobile source volatile organic compound emissions in the

Maricopa area are reduced each year after 2013. Beginning in 2018, mobile source

emissions without Stage II controls are less than mobile source emissions with Stage II

controls, as Stage II controls no longer provide emission reduction benefits, but rather

produce an emissions disbenefit.

It is important to note that the mobile source emissions presented in Table 3-1 either 

completely include or exclude Stage II controls at all gasoline dispensing facilities in the

Maricopa area and do not represent the phased removal of Stage II controls in 2014

through 2018 as scheduled and requested in this revision. However, even conservatively

assuming that all gasoline dispensing facilities do not have Stage II controls beginning in

2014, mobile source emissions without Stage II controls still decline rapidly in the following

years. 

Figure 3-1 displays trend lines of the daily ozone season mobile source volatile organic

compound emissions in the Maricopa area with and without Stage II controls. The trend

line for mobile source emissions without Stage II controls continues to show a decline in

emissions for each calendar year after 2013 in the Maricopa area. Both Figure 3-1 and

Table 3-1 demonstrate that the removal of Stage II controls in the Maricopa eight-hour

ozone nonattainment area will not interfere with attainment of the ozone National Ambient

Air Quality Standard, or reasonable further progress towards attainment, as required by

Section 110(l) of the Clean Air Act.

CONCLUSION

The two analyses described above adequately demonstrate that the scheduled removal

of Stage II controls in the Maricopa eight-hour ozone nonattainment area comply with the

requirements of Section 110(l) of the Clean Air Act. The initial analysis demonstrates that

the increased emissions from the removal of Stage II controls in years 2014 through 2018

are optimally minimized through decommissioning of existing facilities beginning inOctober

2016 and ending in September 2018. The resulting temporary emission increases are tiny

and too small to interfere with attainment, or progress toward attainment, as suggested by

EPA guidance.

The second analysis illustrates that the removal of Stage II controls in the Maricopa eighthour ozone nonattainment area does not interfere with the downward trend in total mobile

source emissions. Both analyses ensure that the scheduled removal of Stage II controls

in the Maricopa eight-hour ozone nonattainment area will not interfere with attainment of

the ozone National Ambient Air Quality Standard, or reasonable further progress towards

attainment, as required by Section 110(l) of the Clean Air Act.

I. INTRODUCTION

The U.S. Environmental Protection Agency (EPA) published a final rule on May 16, 2012,

determining that onboard refueling vapor recovery systems (ORVR) are in widespread use

throughout the motor vehicle fleet. By this final rule, EPA exercised the authority provided

in Section 202(a)(6) of the Clean Air Act to waive the requirement in Section 182(b)(3) for

states to implement Stage II vapor recovery systems at gasoline dispensing facilities in

nonattainment areas classified as Serious and above for the National Ambient Air Quality

Standards for ozone.

This in turn allows states that were required to implement Stage II vapor recovery systems

under Section 182(b)(3) of the Clean Air Act the option to submit to the EPA revised ozone

State Implementation Plans that remove Stage II controls. In response to the May 16,

2012, waiver issued by EPA, the MAG 2014 State Implementation Plan Revision requests

to remove the requirement to install and operate Stage II controls in the Maricopa eighthour ozone nonattainment area for new gasoline dispensing facilities beginning in 2014

and for existing gasoline dispensing facilities beginning in October 2016. All existing

gasoline dispensing facilities in the Maricopa area are scheduled to have Stage II controls

removed by September 30, 2018.

Clean Air Act Section 110(l) requires that any revision to a State Implementation Plan must

demonstrate that the revision does not interfere with attainment of the National Ambient

Air Quality Standards, or reasonable further progress towards attainment. The phased

removal of Stage II controls requested in this revision optimally minimizes the temporary

increases in emissions associated with the removal of Stage II controls in the Maricopa

eight-hour ozone nonattainment area. The temporary emission increases are too small to

interfere with attainment or progress towards attainment.

Chapter II of the Technical Document in Support of the MAG 2014 State Implementation

Plan Revision for the Removal of Stage II Vapor Recovery Controls in the Maricopa EightHour Ozone Nonattainment Area (TSD) describes the EPA recommended equations used

to calculate the areawide impact of Stage II controls on vehicle refueling emissions in the

Maricopa County area. The results of these equations show that beginning in 2018, Stage

II controls no longer provide emission reduction benefits in the Maricopa County area due

to incompatibility issues between gasoline dispensing facilities equipped with vacuumassisted Stage II controls and motor vehicles equipped with ORVR systems. Chapter II

also quantifies the very small, temporary increase in emissions from the phased removal

of Stage II controls from gasoline dispensing facilities in the Maricopa eight-hour ozone

nonattainment area in years 2014 through 2018.

Chapter III of the TSD includes onroad and nonroad modeling that demonstrates the

continued decline in onroad and nonroad volatile organic compound emissions even under

complete removal of Stage II controls beginning in 2014. This provides additional evidence

that removal of Stage II controls will not interfere with attainment of the ozone National

Ambient Air Quality Standards.

I-1
II. AREAWIDE IMPACTS OF STAGE II VAPOR RECOVERY CONTROLS ON

VEHICLE REFUELING EMISSIONS

EPA GUIDANCE EQUATIONS

EPA guidance (EPA, 2012c) indicates that states can use the assessment method

described in Section 3 of the guidance to determine the point in time when onboard

refueling vapor recovery (ORVR) systems achieve equivalent emissions reductions as

compared to the reductions credited to Stage II vapor recovery controls. Three principal

equations are provided in the guidance for assessing areawide impacts of Stage II controls

on vehicle refueling volatile organic compound (VOC) emissions.

EPA Guidance Equation 1: Overall Stage II-ORVR increment

The increment in Equation 1 reflects the calendar year areawide VOC emission reduction

benefit from Stage II controls at gasoline dispensing facilities (GDF) as vehicles equipped

with ORVR systems phase in. A positive value of the increment indicates areawide

emission reduction benefits from Stage II vapor controls, while a negative value indicates

that Stage II controls no longer provide emission reduction benefits due to incompatibility

issues between gasoline dispensing facilities equipped with vacuum-assisted Stage II

controls and the increase in motor vehicles equipped with ORVR systems.

EPA guidance recommends the use of Equation 1 as the key equation for assessing and

demonstrating compliance with the noninterference provisions of Clean Air Act Section

110(l).

EPA Guidance Equation 2: Overall Stage II-ORVR delta

The delta in Equation 2 is the comparison between the Stage II efficiency and the ORVR

efficiency when both refueling VOC emission control technologies are in use together. A

positive value of delta indicates that the Stage II efficiency is higher than the ORVR

efficiency while a negative value represents a higher ORVR efficiency due to incompatibility

issues between vacuum-assisted Stage II controls and increase in motor vehicles with

ORVR systems. 

EPA guidance recommends using Equation 2 as the key equation for assessing and

demonstrating compliance with Clean Air Act Section 193 requirements. As the Maricopa

eight-hour ozone nonattainment area is not subject to the requirements of Section 193,

Equation 2 is included here for completeness sake only.

II-1
EPA Guidance Equation 3: Impact on the refueling VOC emission inventory

Equation 3 quantifies the VOC emission reduction benefits of Stage II controls for each

calendar year as motor vehicles equipped with ORVR systems increase.

Values of the individual variables for the three EPA guidance equations are developed for

the entire Maricopa County area due to data availability and are a conservative estimate

of the areawide impacts of Stage II controls on vehicle refueling emissions in the Maricopa

eight-hour ozone nonattainment area. Description of the individual variables and the data

developed for each variable are described as follows:

QSII - Fraction of gasoline throughput covered by Stage II Vapor Recovery

Systems: The Arizona Department of Weights and Measures (ADWM) provided

a value of 0.95 (95 percent) for Maricopa County. This value is within the range

suggested by EPA guidance for areas like Maricopa County where the Stage II

exemption for independent small business marketers with a gasoline dispensing

throughput of less than 50,000 gallons per month has not been utilized.

QORVR

- Fraction of annual gallons of highway motor gasoline dispensed to

ORVR-equipped vehicles: The values for the years 2006 through 2020 were

obtained from Table A-1, column 4 in the Appendix to the EPA guidance (EPA,

2012c). Section 3.3.3 of the guidance indicates that an area may use national

values in Table A-1 or adjust national values as appropriate depending upon the

local fleet age. To estimate gasoline vehicle fleet age in Maricopa County, gasoline

vehicle registration data on July 7, 2012 for Maricopa County were obtained from

the Arizona Department of Transportation. Vehicle age distribution was derived by

dividing vehicle population for each age by the total population for a specific

gasoline vehicle class. The products of age and age distribution were summed to

calculate the fleet-wide age of a vehicle class for Maricopa County in Table II-1. 

In order to compare national fleet age and Maricopa County fleet age, weighting

factors by vehicle class (distribution of gasoline vehicles in each class) were

developed for both the national fleet and the Maricopa County. Weighting factors

for the national fleet were derived from national vehicle population outputs from

EPA’s Motor Vehicle Emission Simulator (MOVES), while weighting factors for

Maricopa County’s fleet were derived from the July 2012 Maricopa County vehicle

registration data. The weighting factors for each vehicle class were applied to the

national and Maricopa County fleet ages and then summed to calculate the average

fleet age for all gasoline vehicles across the nation and in Maricopa County. As

shown in Table II-2, the average national fleet age is 8.41 years, while Maricopa

County’s average fleet age is 8.68 years. This indicates that the average gasoline

fleet age in Maricopa County is only 0.27 years older than the average national

gasoline fleet age. Due to the similarity between the average national and Maricopa

County fleet ages, the national data in Table A-1 of the EPA guidance were

selected for this variable.

çiuSII- Stage II Vapor Recovery System in-use control efficiency: The ADWM

estimated a value of 67.4% (0.674) based upon an analysis of 316 unannounced

inspections of Stage II controls performed from September 2010 through

September 2012 in Maricopa County.

QSIIva

- Fraction of gasoline throughput dispensed through vacuum-assist type

Stage II Vapor RecoverySystems: The ADWM provided a value of 82.8% (0.828)

based upon distribution records of the types of Stage II control systems used in

Maricopa County.

çORVR- In-use control efficiency for ORVR: The control efficiency for Maricopa

County is 0.98 as recommended by the EPA guidance.

GCi- Projected gasoline consumption, for calendar year of interest: Gasoline

consumption data by month for Maricopa County were provided by the Maricopa

County Air Quality Department for the calendar years 2006 through 2012. The daily

average gasoline consumption for the ozone season (May - September) was

calculated. Historical and future gasoline vehicle daily energy consumption data in

Maricopa County were derived from MOVES2010b runs. MOVES2010b provided

gasoline vehicle daily energy consumption data in mega joule per day, which were

converted to gallons per day using a gasoline heat value of 130,000 Btu/gal. 

Historical (2006-2012) gasoline consumption data for Maricopa County as derived

from MOVES2010b runs underestimated gasoline consumption for Maricopa

County’s fleet when compared to actual historical usage data. To correct for this

underestimation, future gasoline consumption projections from MOVES2010b were

adjusted by using the ratio of actual gasoline consumption to MOVES2010b

gasoline consumption for Maricopa County. The averaged ratio of actual gasoline

consumption to MOVES-derived gasoline consumption for the years 2006 through

2012 is given in Table II-3. The adjusted gasoline consumption projections for the

years 2013 through 2020 are provided in Table II-4. The adjusted gasoline

consumption projection data in Table II-4 were used in calculating the VOC

emission reduction benefits of Stage II controls over time.

EF (g/gal) - Uncontrolled displacement refueling emission factor: This variable

represents the uncontrolled emissions emitted during vehicle refueling and is

calculated by using the following EPA guidance equation:

Arizona values for the dispensed fuel temperature (Td

), and the difference between

storage tank fuel temperature and dispensed fuel temperature (ÄT), are obtained

from Tables A-2 and A-3 of the EPA guidance. The value for Reid Vapor Pressure

(RVP) in Maricopa County is set to 7.0psi to comply with the state statute RVP limit

during the ozone season. The resulting EF for Maricopa County (3.5 g/gal) is

calculated as follows:

CFi

- Compatibility factor: This variable represents an increase in underground

storage tank (UST) vent pipe emissions over normal breathing/emptying loss

emissions per calendar year. This variable increases as more ORVR vehicles refuel

at gasoline dispensing facilities (GDFs) in the presence of vacuum-assisted Stage

II control systems. The compatibility issues occur during refueling ORVR vehicles

at GDFs with vacuum-assist Stage II control systems. As an ORVR vehicle captures

an air vapor mixture from the vehicle fuel tank, the vacuum-assist Stage II system

draws fresh air into the UST instead of an air vapor mixture from the vehicle fuel

tank. The fresh air drawn into the UST increases gasoline evaporation and pressure

in the UST. As a result, fugitive emissions from the UST increase, which causes the

incompatibility problem between ORVR vehicles and vacuum-assisted Stage II

control systems. 

The factor is zero if all GDFs have ORVR-compatible nozzles, or one if all GDFs are

incompatible with ORVR vehicles. The compatibility factor for any given year can

be calculated from either the product of VMTORVR and a constant term of 0.07645

or the product of QORVR and a constant term 0.0777, per EPA guidance. Both

equations result in similar compatibility factors. The compatibility factors for

Maricopa County for the years 2006 through 2020 have been calculated using QORVR

and the constant of 0.0777.

Table II-5 presents the results of EPA Equations 1 through 3 when calculated using the

variables described above. As stated earlier, EPA maintains that Equation 1 is key to

demonstrating compliance with the noninterference provision of Clean Air Act Section

110(l). As such, the results of Equation 1 show that Stage II controls in the Maricopa

County area will no longer provide emission reduction benefits beginning in calendar year

2018 (first year with negative increment value) due to the incompatibility issues between

gasoline dispensing facilities equipped with vacuum-assisted Stage II controls and

increasing numbers of motor vehicles equipped with ORVR systems.

requirement to install and operate Stage II controls at new gasoline dispensing facilities

beginning in 2014 and a two-year phased removal of Stage II controls at existing gasoline

dispensing facilities beginning in October 2016 and ending no later than September 30,

2018. Removal of Stage II controls under the schedule requested in this revision optimally

minimizes the temporary areawide increase in volatile organic compound emissions in the

Maricopa area. 

New Gasoline Dispensing Facilities

The temporary increase in emissions from the construction of new gasoline dispensing

facilities without Stage II controls occurs in 2014 through 2017, since Stage II controls no

longer provide areawide emission reduction benefits beginning in 2018. Increased

emissions from new facilities are calculated by first quantifying the percent of the total

emission reduction benefits from Stage II controls that new facilities account for in 2014

through 2017. Using data provided by the Arizona Department of Weights and Measures

on the number of new and total gasoline dispensing facilities in the Maricopa area for

calendar years 2008 through 2012, the percent of emission reduction benefits from Stage

II controls that are attributable to new gasoline dispensing facilities for calendar years 2008

through 2012 in the Maricopa area is calculated by dividing the number of new gasoline

dispensing facilities by the total number of gasoline dispensing facilities for each calendar

year. Table II-6 lists the percent of Stage II emission reduction benefits associated with

new gasoline dispensing facilities in the Maricopa area for calendar years 2008 through

2012. The average percent of emission reduction benefits associated with new gasoline

dispensing facilities incalendar years 2008 through 2012 is 2.06% as shown in Table II-6.

The average percent of emissions reduction benefits associated with new facilities is next

used to calculate the temporary increase in emissions for new facilities for calendar years

2014 through 2017 in the Maricopa area by multiplying the average percent shown in Table

II-6 (2.06%) by the total emission reduction benefits from Stage II controls in 2014 through

2017 as previously calculated and listed in Table II-5. This calculation results in a

temporary increase of 15 kilograms of volatile organic compound emissions per ozone

season day in 2014 (e.g., 2.06% x 725 kg/day), ten kilograms per ozone season day in

2015, five kilograms per ozone season day in 2016, and one kilogram per ozone season

day in 2017. Table II-7 lists the temporary increase in emissions from new gasoline

dispensing facilities constructed in 2014 through 2017 without Stage II controls in the

Maricopa area.

Existing Gasoline Dispensing Facilities

In order to optimally minimize the temporary increase in emissions from removal of Stage

II controls at existing gasoline dispensing facilities, the removal of Stage II controls at

existing facilities in the Maricopa area are phased in over a two-year period beginning after

the end of the 2016 ozone season (October 2016 through September 2018). The Arizona

Department of Weights and Measures anticipates that the decommissioning of Stage II

controls at existing facilities will be spread evenly over each of the 24 months in October

2016 through September 2018. Decommissioning is expected to occur for existing

facilities during the month when the annually scheduled Stage II controls test would have

occurred. Since it will take 24 months to decommission the over 1,000 existing gasoline

dispensing facilities in the Maricopa area, the older half of existing facilities will

decommission in the first 12 months of the decommissioning period (October 2016 through

September 2017), while the newer half of existing facilities will decommission in the second

12 months of the decommissioning period (October 2017 through September 2018).

A small number of existing gasoline dispensing facilities without Stage II controls will exist

in the 2015 and 2016 ozone seasons before the decommissioning period begins as a

result of new facilities built in 2014 and 2015 without Stage II controls (e.g., in 2015, 2.06%

of existing facilities will not have Stage II controls due to the new facilities built in 2014; in

2016, 4.12% of existing facilities will not have Stage II controls due to new facilities built

in 2014 and 2015). Accordingly, the temporary increase in emissions from existing

facilities in 2015 and 2016 is calculated by multiplying the percent of existing facilities

without Stage II controls by the emission reduction benefits of Stage II in 2015 and 2016. 

In order to calculate the temporary increase in emissions from existing facilities in 2017,

the percent of existing gasoline dispensing facilities in 2017 that will have Stage II controls

removed by the end of the ozone season (September 30, 2017) must be calculated. As

explained above, half of the existing gasoline dispensing facilities with Stage II controls will

be decommissioned between October 2016 through September 2017, with

decommissioning scheduled to occur evenly over each month. Under this schedule,

50.00% of the existing gasoline dispensing facilities will have had Stage II controls

removed by the end of the ozone season. Thus, the temporary increase in emissions from

existing facilities in 2017 is calculated by multiplying the percent of existing facilities without

Stage II controls by the emission reduction benefits of Stage II in 2017.

In 2018, areawide emission reduction benefits from Stage II controls no longer occurs in

the Maricopa area; rather, Stage II controls that remain in place during the 2018 ozone

season produce emission increases due to the incompatibility between Stage II controls

and onboard refueling vapor recovery systems. As such, the temporary increase in

emissions during 2018 are from facilities that have yet to decommission Stage II controls

by the beginning of the 2018 ozone season. The 2018 ozone season begins in May 2018. 

Under the phased-in decommissioning schedule requested in this revision, 79.17% of the

existing gasoline dispensing facilities would have removed Stage II controls by May 2018

(i.e., through April 2018, 19 months of the 24 month decommissioning period has passed,

19 ÷ 24 = 79.17%), leaving 20.83% of existing facilities with Stage II controls still in place. 

The temporary increase in emissions from existing facilities in 2018 is therefore calculated

by multiplying the percent of existing facilities with Stage II controls in place at the

beginning of the 2018 ozone season by the areawide emission disbenefit of Stage II

controls in 2018.

In summary, the temporary increase in emissions associated with the removal of Stage II

controls at existing gasoline dispensing facilities in the Maricopa area in 2015 through 2018

II-11
are listed in Table II-8. The temporary increases from new and existing gasoline

dispensing facilities are summed in Table II-9 to provide the total emission increases

associated with the scheduled removal of Stage II controls in the Maricopa eight-hour

ozone nonattainment area in calendar years 2014 through 2018.

The following chapter of this TSD provides an additional analysis demonstrating that the

removal of Stage II controls beginning in 2014 in the Maricopa area will meet the

requirements of Clean Air Act Section 110(l) by documenting the declining trend in total

mobile source VOC emissions after the removal of Stage II controls in the Maricopa area.

III. DECLINING TREND IN ONROAD AND NONROAD VOLATILE ORGANIC

COMPOUND EMISSIONS AFTER REMOVAL OF STAGE II VAPOR RECOVERY

CONTROLS

This analysis provides evidence that the MAG 2014 Revision complies with Clean Air Act

Section 110(l) by demonstrating that removal of Stage II controls in the Maricopa area does

not alter the downward trend (reasonable further progress) in onroad and nonroad mobile

source volatile organic compound (VOC) emissions in the years 2013 through 2020. 

Nonroad and onroad mobile source emissions with and without Stage II controls were

developed as follows:

NONROAD SOURCE VOC EMISSIONS

The EPA NONROAD2008a model (EPA, 2005 and 2013) was executed to estimate

emissions for nonroad equipment categories, excluding aircraft and locomotive emissions,

in the ozone season months of May through September. Nonroad source emissions were

estimated without Stage II controls on refueling emissions for Maricopa County for the

years 2013 through 2020; the Stage II Control Percent option of the NONROAD2008a

model was set to zero. Monthly minimum, maximum, and average temperatures were

calculated from the 2012 hourly temperatures at the Phoenix Sky Harbor International

Airport monitoring site. Monthly local fuel parameters (i.e., RVP, gasoline and diesel sulfur,

and ethanol content) required by NONROAD2008a as inputs were obtained from the

Arizona Department of Weights and Measures (ADWM). The model runs for future years

were based on the monthly local fuel parameter data for Maricopa County in 2012 provided

by the ADWM. Table III-1 summarizes the monthly temperatures and local fuel inputs for

the ozone season in 2012 used to develop the nonroad emissions.

NONROAD2008a model inputs, including equipment population, activity levels for

equipment, and growth factors, were based on default values derived from national

averages, with the exception of commercial lawn and garden equipment. Equipment

population and activity levels for commercial lawn and garden equipment were based on

the results of a survey performed by ENVIRON as a part of the Cap and Trade Oversight

Committee (CTOC) work (ENVIRON, 2003). The survey results indicated that the

population of commercial lawn and garden equipment in Maricopa County is significantly

lower than the default values in NONROAD2008a, while average annual operating hours

for the equipment are slightly higher than the default values. RunSpec files for

NONROAD2008a model runs are provided in Appendix I.

The average daily nonroad emissions for the ozone season were calculated by dividing the

summed monthly NONROAD2008a emissions for May through September by the number

of days in May through September (153 days). Average ozone season day VOC emissions

from nonroad mobile source emissions without Stage II controls in Maricopa County are

provided in Table III-2.

ONROAD SOURCE VOC EMISSIONS

Onroad mobile source ozone season VOC emissions were calculated without Stage II

controls using the latest version of the EPA Motor Vehicle Emission Simulator

(MOVES2010b), the MAG MOVESLink model, and transportation network assignment data

for years 2012, 2015, and 2025 provided by the MAG Transportation Division. The

transportation network assignment data used in this analysis utilize the population

projections adopted by the MAG Regional Council in June 2013; these projections are

based on the 2010 U.S. Census. Transportation network assignment outputs by the

TransCAD Travel Demand Model (TDM) provide link specific traffic volume, length, 

and travel times. MOVES2010b includes emission factors for off-network and network

(rural restricted access, rural unrestricted access, urban restricted access, and urban

unrestricted access) road types. Off-network includes locations such as parking lots, truck

stops, rest areas, and freight or bus terminals, where the predominant activities are vehicle

starts, parking, and idling. As required in the MOVES guidance (EPA, 2012a), onroad

emission inventories include off-network emissions to account for emissions from vehicle

starts and extended idling activity. To eliminate the Stage II refueling emission control

program from MOVES2010b runs, two fields, “refuelingVaporProgramAdjustment” and

“refuelingSpillProgramAdjustment” in the [County Year] table in the MOVES database,

were set to zero for all calendar years, as described in Appendix F of EPA’s MOVES2010b

User Guide (EPA, 2012a). 

MOVES2010b

MOVES2010b is EPA’s state-of-the-art regulatory emissions model, which replaces the

previous mobile source emissions model, MOBILE6.2 (EPA, 2003). MOVES2010b

estimates national, state, and county level emissions from motor vehicles. Each

MOVES2010b model run requires as input the specification of vehicle types, time periods,

geographical areas, pollutants, vehicle operating characteristics, and road types for a

particular scenario in a Run Specification (RunSpec).

In order to calculate onroad vehicle ozone season day emissions for calendar years 2013

to 2020, MOVES2010b was executed using local input data and transportation network

assignment data for calendar years 2012, 2015, and 2025 and the geographical area of

Maricopa County using the County Domain/Scale and the Inventory Calculation Type

options. An example of the MOVES2010b model RunSpec summaries can be found in

Appendix I.

MOVESLink

MOVESLink is a motor vehicle emissions processing model developed by MAG to estimate

onroad mobile source emissions inventories using MOVES2010b and link level activity data

output by the MAG TransCAD Travel Demand Model (TDM). MOVESLink is used to

perform regional transportation conformity analyses, develop periodic emissions

inventories and evaluate transportation projects and emissions control measures in support

III-3
of State Implementation Plans (SIPs).

MOVESLink was developed in the Python programming language using state-of-the-art

GIS technology. This model is used to (1) read link-level activity data from the MAG

TransCAD traffic assignment, (2) prepare MOVES2010b input data, (3) execute

MOVES2010b, and (4) post-process MOVES2010b results.

MOVES Input Data

MOVES2010b requires detailed local data including fuel data, Inspection and Maintenance

(I/M) programs, meteorological data, vehicle population, source type age distribution,

annual vehicle miles traveled (VMT), monthly/daily/hourly VMT fractions, road type

distribution, average speed distribution, ramp fraction, and Alternative Vehicle and Fuel

Technologies (AVFT). Local input data for MOVES2010b were prepared in accordance

with MOVES technical guidance (EPA, 2012b).

Fuel Data

The fuel data for each month were derived from the fuel inspection results in Maricopa

County provided by the Arizona Department of Weights and Measures (ADWM). The fuel

data for Maricopa County were applied to the entire Maricopa County area using the latest

2012 fuel data obtained from the ADWM. The specific MOVES tables for fuel data, which

are [fuelsupply] and [fuelformulation], are presented in Appendix I. 

I/M Programs

The I/M program data in [IMCoverage] table reflect gasoline vehicle inspection programs

being implemented in Maricopa Area A (MCAQD, 2008). The term “I/M vehicles” denotes

vehicles which are required to undergo an emissions test and inspection under the Arizona

Vehicle Inspection/Maintenance Program. Since participation in the I/M program is

required for all vehicles registered in Area A, with the exception of certain model years and

vehicle classes, it is assumed that 91.6 percent of the vehicles operating within Area A

participate in the I/M program and the rest do not participate in the program (MAG, 2004). 

This percentage reflects the control measures “Tougher Enforcement of Vehicle

Registration and Emissions Test Compliance” and “Expansion of Area A Boundaries,”

described in the MAG Eight-Hour Ozone Redesignation Request and Maintenance Plan

for the Maricopa Nonattainment Area (MAG, 2009). This percentage is directly applied to

the Compliance Factor in the [IMCoverage] table. The same I/M programs were applied

for the entire Maricopa County area. The specific MOVES table for I/M programs is

presented in Appendix I.

Meteorological Data

For MOVES temperature and relative humidity inputs, meteorological data at the Phoenix

Sky Harbor International Airport monitoring site were obtained from the National Climatic

III-4
Data Center (NCDC) for the ozone season (May through September) in 2012. The hourly

average temperature and relative humidity data for each month were used in running

MOVES2010b for Maricopa County. The specific MOVES table [ZoneMonthHour] for

meteorological data is presented in Appendix I.

Vehicle Population

The MOVES source type vehicle population data in Maricopa County for the years 2012

and 2013 were derived from the July 7, 2012 and July 25, 2013 vehicle registration data

provided by the Arizona Department of Transportation (ADOT). The July 2012 and 2013

vehicle registration data were allocated to the twenty-eight MOBILE6.2 vehicle types based

on MOBILE6.2 VMT fractions. Then, the vehicle population by MOBILE6.2 vehicle type

was re-assigned to the thirteen MOVES source types using the match-up table (Table A.1)

in accordance with the EPA technical guidance (EPA, 2012b). For MOVES2010b runs with

the 2012 network assignment data for the year 2012, the vehicle population data derived

from the July 2012 vehicle registration data were utilized. For future years, the vehicle

population data derived from the latest July 2013 vehicle registration were adjusted by

applying the ratio of the projected Maricopa County population in a future year to those in

2013. The specific MOVES table [SourceTypeYear] for vehicle population is presented in

Appendix I.

Source Type Age Distribution

MOVES2010b categorizes vehicles according to vehicle classes and model years. The

source type age distribution was prepared using EPA's data converter

(registrationdistributionconverter-_veh16.xls) that takes the registration distribution input

file of MOBILE6.2 and converts it to the appropriate MOVES age distribution input table

[SourceTypeAgeDistribution]. The source type age distribution for Maricopa County was

applied. The specific MOVES table for source type age distribution is presented in

Appendix I.

Annual VMT

Since MOVES2010b requires annual VMTs by Highway Performance Monitoring System

(HPMS) vehicle type as input, the daily VMTs by HPMS vehicle type were derived from (1)

the traffic assignment data provided by the MAG Transportation Division, (2) the MOVES

default VMT fraction for Maricopa County, and (3) the daily VMTs by facility type and the

estimated percentages of daily vehicle travel by vehicle type and highway functional

classification provided by ADOT. The daily VMTs by HPMS vehicle type were multiplied

by 366 days for 2012 or 365 days for other years to obtain the annual VMTs by HPMS

vehicle type. The specific MOVES table [HPMSvTypeYear] for annual VMT is presented

in Appendix I.

Road Type Distribution

The road type distribution by HPMS vehicle type was derived from the traffic assignment

III-5
data provided by the MAG Transportation Division and the MOVES default VMT fraction

for Maricopa County. As suggested in EPA technical guidance (EPA, 2012b), the same

road type distribution by HPMS vehicle type was used for all MOVES source types within

an HPMS vehicle class. The specific MOVES table [RoadTypeDistribution] for road type

distribution is presented in Appendix I.

VMT Fraction

The month/day/hour VMT fractions for Maricopa County were developed from data

recorded by continuous traffic counters on freeways (ADOT Freeway Management

System) and arterials (Phoenix Automatic Traffic Recorders) during the year 2007. The

specific MOVES tables [MonthVMTFraction], [DayVMTFraction], and [HourVMTFraction]

for VMT fractions are presented in Appendix I.

Average Speed Distribution

In MOVES2010b, vehicle power, speed, and acceleration have a significant effect on

vehicle emissions for all pollutants. MOVES2010b estimates those emissions effects by

assigning activity to operating mode distributions, which are determined by the distribution

of vehicle hours traveled (VHT) by average speed. As recommended in EPA technical

guidance (EPA, 2012b), estimates of local average speeds were derived by MOVESLink

using the traffic assignment data provided by the MAG Transportation Division. To develop

the average speed distribution, VHTs in sixteen speed bins were accumulated separately

for each hour of the day, source type, and road type. Then, the average speed distribution

was calculated by normalizing VHTs in sixteen speed bins for each hour of the day, source

type, and road type. The same methodology was applied to develop the speed estimates

for the entire Maricopa County area. The specific MOVES table [AvgSpeedDistribution]

for the average speed distribution is presented in Appendix I.

Ramp Fraction

The ramp fraction represents the percent of VHT on ramps on both rural restricted roads

(road type 2) and urban restricted roads (road type 4). The fraction of VHT on ramps was

derived by dividing the total VHTs on ramps by the total VHTs for each restricted road type. 

The VHTs were estimated from the traffic assignment data provided by the MAG

Transportation Division. The specific MOVES table [RoadType] for ramp fraction is

presented in Appendix I.

AVFT Strategy

MOVES2010b allows users to modify the fuel engine fraction using different fuels and

technologies in each model year in order to reflect local conditions. The fleet information

for transit buses for the model years 1997 through 2012 provided by Valley Metro was

used to prepare the AVFT input file. Since the fleet data are available only for specific

model years, MOVES2010b default values were obtained from the [fuelEngFraction] table

III-6
in the MOVES default database and used for the rest of the model years. The specific

MOVES table [AVFT] is presented in Appendix I.

Onroad VOC Emissions

Onroad VOC emissions for Maricopa County without Stage II controls were calculated for

five months of the ozone season (May through September) using transportation network

assignment data for the years 2012, 2015 and 2025. The onroad VOC emissions total for

the five-month ozone season was divided by the total number of days in the ozone season,

153 days, for the individual years. Consequently, ozone season average daily VOC

emissions were calculated for the years 2012, 2015, and 2025 in Table III-3.

Ozone season average daily VOC emissions for the years 2013 and 2014 were derived

by interpolating ozone season average daily VOC emissions for 2012 and 2015, and those

for the years 2016 through 2020 were derived by interpolating emissions for 2015 and

2025. The ozone season average dailyVOC emissions from onroad mobile source without

Stage II controls in Maricopa County for the years 2013 through 2020 are presented in

Table III-4. 

SUMMARY OF NONROAD AND ONROAD VOC EMISSIONS WITH AND WITHOUT

STAGE II CONTROLS

The emission reduction benefits of Stage II controls in Maricopa County were calculated

in Chapter II of this TSD according to equations recommended by recent EPA guidance

(EPA, 2012c) and are listed in Table II-5. In order to calculate mobile source emissions

with Stage II controls, the emission reductions benefits of Stage II controls listed in Table

II-5 were subtracted from the sum of the nonroad and onroad mobile source emissions

listed in Tables III-2 and III-4. 

Table III-5 provides a summary of daily ozone season mobile source VOC emissions with

and without Stage II controls in Maricopa County. It is important to note that the mobile

source emissions presented in Table III-5 either completely include or exclude Stage II

controls at all gasoline dispensing facilities in the Maricopa area and do not represent the

phased removal of Stage II controls in 2014 through 2018 as scheduled and requested in

this revision. However, even conservatively assuming that all gasoline dispensing facilities

do not have Stage II controls beginning in 2014, mobile source emissions without Stage

II controls still decline rapidly in the following years. 

It is clear from Table III-5, that even when Stage II controls are no longer in place, mobile

source VOC emissions continue to decline. Figure III-1 displays the data in Table III-5 by

showing the trend lines of mobile source VOC emissions with and without Stage II controls

in 2013 through 2020 in Maricopa County. Figure III-1 demonstrates that removal of Stage

II controls in the Maricopa eight-hour ozone nonattainment area will not interfere with

attainment, or reasonable further progress towards attainment, as required by Clean Air

Act Section 110(l).

This is the options file for the NONROAD program.

The data is sperated into "packets" bases on common

information. Each packet is specified by an

identifier and a terminator. Any notes or descriptions

can be placed between the data packets.

9/2005 epa: Add growth & tech years to PERIOD packet

 and Counties & Retrofit files to RUNFILES packet. 

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

 PERIOD PACKET

This is the packet that defines the period for

which emissions are to be estimated. The order of the

records matter. The selection of certain parameters

will cause some of the record that follow to be ignored.

The order of the records is as follows:

1 - Char 10 - Period type for this simulation.

 Valid responses are: ANNUAL, SEASONAL, and MONTHLY

2 - Char 10 - Type of inventory produced.

 Valid responses are: TYPICAL DAY and PERIOD TOTAL

3 - Integer - year of episode (4 digit year)

4 - Char 10 - Month of episode (use complete name of month)

5 - Char 10 - Type of day

 Valid responses are: WEEKDAY and WEEKEND

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

/PERIOD/

/END/

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

 OPTIONS PACKET

This is the packet that defines some of the user

options that drive the model. Most parameters are

used to make episode specific emission factor

adjustments. The order of the records is fixed.

The order is as follows.

1 - Char 80 - First title on reports

2 - Char 80 - Second title on reports

3 - Real 10 - Fuel RVP of gasoline for this simulation

4 - Real 10 - Oxygen weight percent of gasoline for simulation

5 - Real 10 - Percent sulfur for gasoline

6 - Real 10 - Percent sulfur for diesel

7 - Real 10 - Percent sulfur for LPG/CNG

8 - Real 10 - Minimum daily temperature (deg. F)

9 - Real 10 - maximum daily temperature (deg. F)
10 - Real 10 - Representative average daily temperature (deg. F)

11 - Char 10 - Flag to determine if region is high altitude

 Valid responses are: HIGH and LOW

12 - Char 10 - Flag to determine if RFG adjustments are made

 Valid responses are: YES and NO

 REGION PACKET

This is the packet that defines the region for which

emissions are to be estimated.

The first record tells the type of region and

allocation to perform.

Valid responses are:

US TOTAL - emissions are for entire USA without state

 breakout.

50STATE - emissions are for all 50 states

 and Washington D.C., by state.

STATE - emissions are for a select group of states

 and are state-level estimates

COUNTY - emissions are for a select group of counties

 and are county level estimates. If necessary,

 allocation from state to county will be performed.

SUBCOUNTY - emissions are for the specified sub counties

 and are subcounty level estimates. If necessary,

 county to subcounty allocation will be performed.

The remaining records define the regions to be included.

The type of data which must be specified depends on the

region level.

US TOTAL - Nothing needs to be specified. The FIPS

 code 00000 is used automatically.

50STATE - Nothing needs to be specified. The FIPS

 code 00000 is used automatically.

STATE - state FIPS codes
COUNTY - state or county FIPS codes. State FIPS

 code means include all counties in the

 state.

SUBCOUNTY - county FIPS code and subregion code.

 SOURCE CATEGORY PACKET

This packet is used to tell the model which source

categories are to be processed. It is optional.

If used, only those source categories list will

appear in the output data file. If the packet is

not found, the model will process all source

categories in the population files.

 This is the packet that lists the names of output files

 and some of the input data files read by the model. If

 a drive:\path\ is not given, the location of the

 NONROAD.EXE file itself is assumed. You will probably

 want to change the names of the Output and Message files

 to match that of the OPTion file, e.g., MICH-97.OPT,

 MICH-97.OUT, MICH-97.MSG, and if used MICH-97.AMS.

41-2131. Definitions

4. “Stage I vapor recovery system” means a combination of pipes and hoses that

creates a closed system between the vapor spaces of an unloading gasoline cargo tank

and a receiving storage tank so that vapors displaced from the storage tank are transferred

to the gasoline cargo tank being unloaded.

5. “Stage II vapor recovery system” means a system where at least ninety per cent

by weight of the gasoline vapors that are displaced or drawn from a vehicle fuel tank during

refueling are transferred to a vapor-tight holding system or vapor control system.

41-2132. Stage I vapor recovery systems

A. A person shall not offer for sale, sell, install or use a new gasoline stage I vapor

recovery system, or any new or rebuilt component parts of the system, unless the system

or component part has been certified by the California air resources board as of March 31,

2001 or after that date, or has been approved by a third party accredited to test equipment

and recognized by industry and the department, and has not been rejected by the

department. The department shall maintain and keep current a list of stage I vapor

recovery systems and component parts that are approved by the department. Only those

systems that are approved shall be used in this state. All certified vapor recovery

components must be clearly identified by a permanent identification affixed by the certified

manufacturer or rebuilder.
