I. INTRODUCTION

On September 16, 1997, the U.S. Environmental Protection Agency (U.S. EPA)

promulgated an 8

- hour ozone National Ambient Air Quality Standard (NAAQS or

standard) of 0.08 parts per million (ppm). When d esignating the nonattainment areas

for this standard in 2004

, U.S. EPA split the former Southeast Desert 1

- hour ozone

nonattainment area. The Riverside Count y portion of the Southeast Desert became the

Coachella Valley 8

- hour ozone nonattainment area (Coachella Valley), while the

Southwestern portion of San Bernardino County and the n ortheastern portion of

Los Angeles County became the Western Mojave Desert 8

- hour nonattainment area

(Western Mojave Desert). These areas were given different classifications by U.S. EPA,

with the Coachella Valley classified as serious and the Western Mojave Desert

classified as moderate.

The Clean Air Act (Act) requires states wi th nonattainment areas to prepare and submit

State Implementation Plans (SIPs) to demonstrate how the area s will attain air quality

standard s

. State law assigns the Air Resources Board ( ARB) the primary responsibility

to ensure California's compliance wit h the Act. Traditionally, ARB shares that

responsibility with local air districts through regulatory actions, incentive programs, and

defined SIP commitments for further action to achieve emission reductions necessary

for attainment of the standard . The State also has an expectation that the federal

government will provide necessary emission reductions from sour ces under U.S. EPA’s

authority.

In 2007 and 2008, ARB submitted SIPs to U.S. EPA for the Coachella Valley (2007

Coachella Valley Plan) and the Western Mojave Desert (2008 Western Mojave Desert

Plan). These plans included requests that U.S. EPA reclassify both areas to

appropriate classifications given the amount of ozone and ozone precursors transported

into the areas from the South Coast Air Ba sin and the much lon ger deadline the South

Coast Air Basin has to reduce emissions and attain the standard

.

T he 2007 Coachella Valley Plan and the 2008 Western Mojave Desert Plan included

u pdated air quality data, emission inventories

, control strategies ( based on State, local,

and federal measures ), modeled attainment demonstrations

, reasonable further

progress (RFP) demonstrations

, and contingency measures.

The attainment demonstrations in the 2007 Coachella Valley Plan and the 2008

We stern Mojave Desert Plan outlined stra tegies for achieving the 1997 8

- hour ozone

standard in the Coachella Valley and the Western Mojave Desert. The attainment

demonstration relied on the statewide measures and commitments in California's 2007

State Imple mentation Plan f or Federal PM2.5 and 8

- Hour Ozone Standards (2007 State

Strategy) to provide the needed reductions. Since 2007, ARB has adopted and

implemente d measures from the 2007 State S trat egy.

The 2007 Coachella Valley Plan and the 2008 Western Moja ve Desert Plan included

RFP demonstrations using U.S. EPA guidance at that time. That guidance allowed

emission reductions from sources outside the nonattainment area s to show progress

### 2

toward attainment. U.S. EPA later determined that using emissions fro m sources

outside a nonattainment area was inappropriate for RFP purposes, and revised its RFP

policy to limit emission reductions to sources w ithin a nonattainment area.

ARB is revising the 2007 Coachella Valley Plan and the 2 008 Western Moja ve Desert Plan

(2014 Update) to reflect the new U.S. EPA guidance for the RFP demonstration and

updated emission inventories . The 2014 Update demonstrate s that the required RFP

milestones are met through adopted measures along with additional emission red uctions

needed to meet the RFP contingency requirement

. The 2014 Update includes updated

emission inventories, attainment demonstrations, RFP demonstrations, new transportation

conformity budgets, and provides vehicle miles traveled (VMT) offsets demonstr ations.

The 2014 Update demonstrates that the adopted regulations will provide the emission

reductions necessary to achieve attainment of the 0.08 ppm 8

- hour ozone standard in

the Coachella Valley and the Western Mojave Desert nonattainment areas by their

attainment date and meet RFP requirements in the milestone years. The 2014 Update

also sets transportation conformity budgets for 2014, 2017 and 2018, and i ncludes VMT

offset demonstrations based on guidance issued by U.S. EPA in August 2012.

Staff Recommendation

Staff recommends that the Board adopt the proposed 2014 Update for the 2007

Coachella Valley Plan and the 2008 Western Mojave Desert Plan as a r evision to the

California SIP.

### 3

II. COACHELLA VALLEY UPD ATE

The 2014 Update revises the 2007 Coachella Valley Plan that was adopted and

submitted to U.S . EPA as a SIP revision on November 28, 2007. The 2007 Coachella

Valley Plan outlined a strategy for ac hieving the 1997 0.08 ppm 8

- hour o zone standard

in the Coachella Valley. The 2007 Coachella Valley Plan also included a request that

U.S. EPA reclassify the Coachella Valley to severe

- 15. On May 5, 2010, U.S. EPA

approved the reclassification to severe

- 1 5 but did not take action on the attainment

demonstration or other planning requirements of the Act ( such as the RFP

demonstration )

. The 2014 U pdate provides information to support U.S. EPA ap proval of

the 2007 Coachella Valley Plan.

Emission Inventory Update

An emission inventory is a critical tool used to evaluate, control, and mitigate air

pollution. The emission inventory is a systematic listing of the sources of air pollutants

along with the amount of pollutants emitted from each source or category over a given

time period. For ozone, the emission inventory is a summer season inventory, which

reflects the activity levels and conditions present when higher ozone levels occur in the

Southern California r egion.

Appendix A contains a detailed inventor y of the two ozone precursors, reactive organic

gases (ROG) and oxides of nitrogen (NOx)

, for the Coachella Valley. The 2007

Coachella Valley Plan relied in part on emission reduction commitments from the 2007

State Strategy. M obile sources are the large st contributors to ozone

- forming emissions

in the Coachella Valley . A doption of the ARB in

- use fleet rules for on

- road trucks and

off

- road equipment provided the emission reductions needed to meet this commitment

. The emission inventory has been updated to incorporate the benefits of these rules as

well as other adopted rules post 2007, new economic forecast s

, and updated

transportation activity projections provided by the Southern California Ass ociation of

Governments (SCAG). The 2014 Update demonstrate s that emissions expressed as

tons per day (tpd) are lower than assume d in the 2007 Coachella Valley Plan (Table 1).

Attainment Demonstration Update

The 2007 Coachella Valley Plan used photochemical modeling to demonstrate that the

proposed emission reduction strategy would result in the level of reductions necessary

to bring the Coachella Valley into attainment for the 0.08 ppm 8

- hour ozone standard by

2018, the attainment deadlin e for severe

- 15 nonattainment areas.

The model ing used in the 2007 Coachella Valley Plan determined the percentage of

emission reductions needed from the base year for the Coachella Valley to reach

attainment ( 20% ROG and 53 % NOx). The analysis in the 2014 Update verifies that the

emission reductions in the new inventory (3 0 % ROG and 59% NOx) exceed the

percentage of emission reductions calculated in the modeled attainment demonstration

from the 2007 Coachella Valley Plan (Table 2).

** Percentages may be slightly different due to rounding

### 5

Since the revised inventory changed both the base year and attainment year emission

estimates

, the 2014 Update attainment analysis, to be conservative, re calculates the

attainment target by applyi ng the percentage of NOx and ROG emission reductions

needed in the 2007 Coachella Valley Plan to the upda ted invento ry, resulting in new

NOx and ROG emission targets, expressed as tons per day. Those targets are then

compared to the updated inventory, which includes the effects of new rules, to assess

current progress toward attainment of the standard. The analysis is detailed in

Appendix B. It shows that adopted controls will provide the new ROG and NOx

reductions needed, from 2002 levels, to attain the standard.

Ozone in the Coachella Valley is significantly affected by emissions transported from

the So uth Coast Air Basin. While the updated Coachella Valley inventory predicts that

emissions will meet their attainment targets before the 2018 deadline, the attainment

target of 2018 has been retained due to the extent of transported emissions into the

Coac hella Valley fr om the South Coast Air Basin.

Reasonable Further Progress Demonstration Update

The Act requires RFP demonstrations to ensure that between the base year and the

attainment year, an area is making continued and steady progress toward attaining air

quality standards.

Section 182(b)(1)(A) of the Act requires nonattainment areas classified as moderate

and above to achieve a 15 percent reduction of ROG within six years of the

nonattainment desi gnation. Section 182(c)(2)(B) requires further emission reductions of

ROG or NOx

, in areas classified as serious and above, of three percent per year after

the initial six year period. Finally, t he RFP demonstration must also include contingency

emission reductions available if an area fails to meet the required milestone year

emission reduction targets.

The 2007 Coachella Valley Plan submittal to U.S. EPA demonstrated RFP in

accordance with U.S. EPA’s implementation rule and guidance at the time, which

allowed the inclusion of ozone precursor emissions transported from upwind areas.

Since that time, U.S. EPA determined it was no longer appropriate to include emissions

from sources outside the nonattainment area in the RFP demonstration and revised its

RFP policy to limit emission reductions to sources within the nonattainment area.

ARB staff has revised the RFP demonstration using the newly updated emissions

inventory and reflecting the most recent U.S. EPA implementation rule and technical

guidance, which no longer allow the inclusion of upwind transport area emission

reductions.

Appendix C demonstrates that the Coachella Valley nonattainment area meets the RFP

targets in all milestone years.

### 6

Transportation Conformity Budgets Update

Transportation conformity is a provision of the Act that requires transportation planning

agencies to demonstrate that their transportation plans, funding programs, and projects

are consistent with or conform to the SIPs purpose of achieving expeditious at tainment

of the standard s . The Act distinguishes transportation actions [those undertaken by the

Federal Highway Administration (FHWA) or the Federal Transit Administration (FTA)]

from all other federal actions.

Metropolitan Planning Organizations (MPOs) must make findings that the regional

transportation plans (RTPs) and transportation improvement programs (TIPs) conform

to the SIP. They submit this conformity finding along with the RTP and TIP to FHWA

and FTA for approval. The conformity finding must d emonstrate that the emissions

associated with the RTP and TIP do not exceed “emission budgets” that are contained

in the SIP. An emissions budget is the maximum level of emissions from on

- road motor

vehicles that ensures an area makes progress toward clea n air and ultimately meets air

quality stan dards by the mandated deadline.

The ARB Early Progress Plans Demonstrating Progress Toward Attaining the 8

- hour

National Air Quality Standard for Ozone and Setting Transportation Conformity Budgets

for Ventura Cou nty, Antelope Valley

- Western Mojave Desert, Coachella Valley, Eastern

Kern County, Imperial County was submitted to U.S. EPA on March 24, 2008. The

U .S. EPA published an adequacy finding on the Coachella Valley motor vehicle

emissions budgets on May 5, 2 008, effective May 20, 2008. Transportation conformity

budgets were established for ROG and NOx using the California EMissions FACtor

Model (EMFAC 2007) and included off

- model reductions from adopted rules not

reflected in EMFAC 2007.

The updated emission budgets have been developed with EMFAC 2011 using the latest

SCAG VMT data and speed distributions where available. On March 6, 2013, U.S. EPA

a pproved the use of this latest version of the California EMFAC model for use in SIP

development.

The updated transportation conformity budgets include a safety margin to provide

flexibility to adjust for uncertainties that may affect on

- road mobile emission estimates.

The safety margin has been included in both the RFP and attainment demonstrations

( see Appendix B and C).

The updated transportation conformity budgets are applicable to the federal 0.08 ppm

8

- hour ozone standard for the Coachella Valley, and ensure that on

- road emissions will

be consistent with the attainment demonstration in future y ears. This technical revision

of the transportation conformity budgets accounts for the current emission inventory

included in this update, and includes transportation conformity budgets for the years

2014, 2017, and 2018 (see Appendix D).

### 7

Ozone Vehicle Miles Traveled Offset Demonstration

Section 182(d)(1)(A) of the Act requires that SIPs for areas classified as severe and

above include a demonstration that “...identifies and adopts specific enforceable

transportation control strategies and transportation control measures to offset any

growth in emissions from growth in vehicle miles traveled or numbers of vehicle trips in

such area....”. 1 

### Appendix E to this 2014 Update includes a VMT offset demonstration

for the Coachella Valley that complies with the Ac t by demonstrating that emission

increases due to VMT growth in the SIP timeframe are appropriately offset by

transportation control strategies and transportation control measures.

III. WESTERN MOJAVE DESER T UPDATE

The 2014 Update revises the 2008 Wester n Mojave Desert Plan that was adopted and

submitte d to U.S. EPA as a SIP revision on July 22, 2008. The 2008 Western Mojave

Desert Plan outlined a strategy for achieving the 1997 0.08 ppm 8

- hour ozone standard

in the Western Mojave Desert.

In 2008, phot ochemical modeling of the Mojave Desert Air Basin indicated that the

Western Mojave Desert, then classified as a moderate nonattainment area, would not

meet the emission reduction target required for attainment of the standard by the

moderate attainment de adline. The 2008 Western Mojave Desert Plan demonstrated

that the proposed emission reduction strategy would bring the Western Mojave Desert

into attainment by 2020, the attainment deadline for severe

- 17 nonattainment areas.

The 2008 Western Mojave Desert Plan therefore included a request that U.S. EPA

reclassify the Western Mojave Desert from moderate to severe

- 17.

U.S. EPA later determined that the Act only allowed reclassification to severe

- 15 and

not severe

- 17. This determination was based on section 181(b)(3) of the Act that

permits reclassification only to the classifications listed in Table 1 of the Act section

181(a), which does not include severe

- 17. 2 

### On March 14, 2012, ARB requested that

U.S. EPA reclassify the Western Mojave Desert from moderate to severe

- 15 rather than

severe

- 17 . O n June 7, 2012, U.S. EPA reclassified Western Mojave Desert to

severe

- 15 but did not take action on the attainment demonstration or other planning

requirements of the Act, such as the RFP demonstration . The 2014 U pdate provides

information to support U.S. EPA ap proval of the 2008 Western Mojave Desert Plan

.

Emission Inventory Update

An emissions inventory is a critical tool used to evaluate, control, and mitigate air

pollution. The emissions inventory is a s ystematic listing of the sources of air pollutants

along with the amount of pollutants emitted from each source or category over a given

time period. For ozone, the emissions inventory is a summer season inventory which

reflects the activity levels and co nditions present when higher ozone levels occur in t he

Southern California region.

Appendix A contains a detailed inventory of the two ozone precursors, reactive organic

gases (ROG) and oxides of nitrogen (NOx)

, for the Western Mojave Desert. The

inventory has been updated since the previous submission to U.S. EPA as part of the

2007 State Strategy

. The updated inventory incorporat es implementation of control

measures since 2007, new economic forecast s

, and updated transportation activity

projections provided by the Southern California Ass ociation of Governments (SCAG).

The 2014 Update demonstrates that emissions are lower than assumed in the 2008

Western Mojave Desert Plan (Table 3 ).

Attainment Demonstration Update

The modeling used in the 2008 Western Mojave Desert Plan determined the percentage

of emission reductions needed from the base year of 2002 for the Western Mojave

Desert to reach attainment in 2020 (

- 2% ROG, 32% NOx). With the classification

change to severe

- 15, the attainment year in the 2014 Update is 2018. The analysis in

the 2014 Update demonstrates that the Western Mojave Desert achieves a greater

percentage of emission reductions by 2018 (23% ROG, 51% NOx) than the percentage

reductions needed as determined by the 2008 Western Mojave Desert Plan to attai n in

2020, the attainmen t year in the 2008 Western Mojave Desert Plan (Table 4 ).

### Since the revised inventory changed both the base year and attainment year emission

estimates, the 2014 Update attainment analysis, to be conservative, recalculates the

attainment target by applying the percentage of NOx and ROG emission reductions

needed in the 2008 Western Mojave Desert Plan to the updated inventory, resulting in

new NOx and ROG emission targets, expressed as tons per day. Those targets are

### 10

then compared to the updated inventory, which includes the effects of new rules, to

assess current progress toward attainment of the standard. The analysis is detailed in

Appendix B. It shows that adopted controls will provide the new ROG and NOx

reductions needed, from 2002 levels, to attain the standard

.

While the updated Western Mojave Desert inventory predicts that emission level s will

meet attainment targets before the 2018 deadline for severe

- 15 areas, ozone in the

Western Mojave Desert is significantly affected by emissions transported from outside

areas. Due to the amount of emissions transported into the Western Mojave Desert

from the South Coast Air Basin, the attainment target of 2018 is being retained in the

2014 Update.

Reasonable Further Progress Demonstration Update

The Act requires RFP demonstrations to ensure that between the base year and the

attainment year, an area is making continued and steady progress toward attaining air

quality standards.

Section 182(b)(1)(A) of the Act requires nonattainment areas classif ied as moderate

and above to achieve a 15 percent reduction of ROG within six years of the

nonattainment designation. Section 182(c)(2)(B) requires further emission reductions of

ROG or NOx in areas classified as serious and above, of three percent per ye ar after

the initial six year period. Finally, the RFP demonstration must also include contingency

emission reductions available if an area fails to meet the required interim milestone year

emission reduction targets.

The 2008 Western Mojave Desert Plan s ubmittal to U.S. EPA demonstrated RFP in

accordance with U.S. EPA’s implementation rule and guidance, which at the time

allowed the inclusion of ozone transport from upwind areas. Since that time, U.S. EPA

determined it was no longer appropriate to includ e emissions from sources outside the

attainment area in an RFP demonstration and revised its RFP policy to limit emission

reductions to sources within a nonattainment area. ARB staff has revised the RFP

demonstration using the newly updated emissions inve ntory and reflecting the most

recent U.S. EPA implementation rule and technical guidance, which no longer allow the

inclusion of upwind t ransport area emission reductions.

As shown in Appendix C, the Western Mojave Desert nonattainment area met the RFP

t argets in all milestone years, except 2008, when the area was required to meet the

target solely through reductions in ROG. The 15 percent ROG

- only target was

achieved by 2011 and the remaining targets were met through 2018 . The additional

reductions nec essary for RFP contingency were met in all years

.

Transportation Conformity Budgets Update

Transportation conformity is a provision of the Act that requires transportation planning

agencies to demonstrate that their transportation plans, funding programs , and projects

are consistent with or conform to the SIP’s purpose of achieving expeditious attainment

### 11

of the standards. The Act distinguishes transportation actions [those undertaken by

FHWA or FTA ] from all other federal actions.

MPOs must make findings that the RTPs and TIPs conform to the SIP. They submit

this conformity finding along with the RTP and TIP to FHWA and FTA for approval. The

conformity finding must demonstrate that the emissions associated with the RTP and

TIP do not exceed “emission budgets” contained in the SIP. An emissions budget is the

maximum level of emissions from on

- road motor vehicles that ensures an area makes

progress toward clean air and ultimately meets air quality standards by the mandated

deadline.

The ARB Early Progress Plans Demonstrating Progress Toward Attaining the 8

National Air Quality Standard for Ozone and Setting Transportation Conformity Budgets

for Ventura County, Antelope Valley

- Western Mojave Desert, Coachella Valley, Eastern

Kern Cou nty, Imperial County was submitted to U.S. EPA on March 24, 2008. The

U.S. EPA published an adequacy finding on the Western Mojave Desert motor vehicle

emissions budgets on May 5, 2008, effective May 20, 2008. Transportation conformity

budgets were est ablished for ROG and NOx in 2009 using the EMFAC 2007 and

included off

- model reductions from adopted rules not reflected in EMFAC 2007.

The updated emission budgets have been developed with EMFAC 2011 using the latest

SCAG VMT data and speed distributions where available. On March 6, 2013, U.S. EPA

announced the availability of this latest version of the California EMFAC model for use

in SIP development.

The updated budgets include a safety margin to provide flexibility to adjust for

uncertainties that may affect on

- road mobile emission estimates. The safety margin has

been included in both the RFP and attainment demonstrations (see Appendix B and C).

The budgets are applicable to the federal 0.08 ppm 8

- hour ozone standard for the

Western Mojave Dese rt nonattainment area, and ensure that on

- road emissions will be

consistent with the attainment demonstration in future years. This technical revision of

the transportation conformity budgets accounts for the current emission inventory

included in this up date, and includes transportation conformity budgets for the years

2014, 2017, and 2018 (see Appendix D).

Ozone Vehicle Miles Traveled Offset Demonstration

Section 182(d)(1)(A) of the Act requires that SIPs for areas classified as severe and

## Appendix A : Updated Emission Inventory

The 2014 U pdate includes an updated 200 8 baseline emission inventory. T he inventory

was based on 200 8 emissions an d activity levels and emissions in other years were

back cast ed or forecast ed from the 2008 base line inventory. The inventory reflects rules

received through September 2012

. This update incorporates updated emission s

, benefits from regulations, activity data provided by SCAG for on

## Appendix E : Vehicle Miles Traveled Offset Demonstration

The requirement to offset growth in vehicle miles traveled (VMT) is contained in

section 182(d)(1)(A) of the federal Clean Air Act (Act). This section applies to areas

classified as severe or extreme nonattainment of the National Ambient Air Quality

Standard (NAAQS) for ozone. Both, t he Coachella Valley and Western Mojave Desert

ozone nonattainment area s are currently designated as severe

- 15 for the 8

- hour ozone

NAAQS and are subject to this requirement. This demonstration is included as part of

the Update t o the 20 07 8

- hour ozone State Implementation Plan for the Coachella

Valley and Western Mojave Desert (2014 Update) to address the requirements of

section 182(d)(1)(A).

Background

In 1997, the U.S. Environmental Protection Agency (U.S. EPA) replaced the 1

- h our

ozone standard set in 1979 with an 8

- hour standard of 0.08 ppm (62 FR 38856

(July 18, 1997)). The U.S. EPA promulgated rules implementing the new standard.

The “Phase 1” rule was issued on April 30, 2004 (69 FR 23951). That rule included

anti

- backsl iding requirements that meant that many requirements in place as a result of

not attaining the 1

- hour NAAQS remained applicable even after the revocation of that

standard, which was effective June 2005 (40 CFR §51.905(a)(1) and §51.900(f) ) . In

particular, an area that was classified as Severe for the 1

- hour standard would remain

subject to the VMT emissions offset requirement even if it would not otherwise have

been subject to that requirement based on its classification under the new 8

- hour ozone

standard (40 CFR §51.900(f)(11)) . The U.S. EPA’s P hase 2 rule, issued on

November 29, 2005 (70 FR 71612) required that areas classified as severe or e xtreme

under the new 8

- hour standard would also be subject to the VMT offset requirement.

Litigation of the Vehic le Miles Traveled Offset Requirement

Previous to the litigation described below, VMT offset demonstrations addressed the

requirements of s ection 182(d)(1)(A) according to U.S. EPA ’s longstanding

interpretation that no further transportation control measure s (TCM) are necessary if

aggregate motor vehicle emissions are projected to decline each year from the base

year of the plan to the attainment year.

Subsequent to Phase 1 and 2 implementation rules, a decision of the Ninth Circuit Court

of Appeals in Association of Irritated Residents (AIR) v U.S. EPA (reprinted as amended

on January 27, 2012, 632 F.3d 584, 9th Cir. 2011 ) rejected U.S. EPA ’s interpretation of

the Act, which had provided the basis for U.S. EPA’s previous approvals of other VMT

offset de monstrations in district plans. With the AIR decision, the Court determined that

the Act requires additional transportation control strategies (TCS) and TCMs whenever

vehicle emissions are projected to be higher than would have been had VMT not grown,

eve n if aggregate vehicle emissions are decreasing.

U.S. EPA Guidance on Vehicle Miles Traveled Offset Requirement

In August 2012, U.S. EPA issued guidance entitled “Implementing Clean Air Act Section

182(d)(1)(A): Transportation Control Measures and Tran sportation Control Strategies to

Offset Growth in Emissions Due to Gro wth in Vehicle Miles Travelled.” Among other

things, U.S. EPA’s guidance points out that in the AIR decision the Court omitted any

reference to “tra nsportation control strategies” (TCS s ) , which are not defined in the Act

or U.S. EPA regulation, are eligible to offset growth in emissions due to growth in VMT.

The U.S. EPA’s new guidance indicates that technology improvements such as vehicle

technology improvements, motor vehicle fuels, a nd other control strategies that are

transportation

- related could be used to offset increases in emissions due to VMT.

U.S. EPA’s revised guidance sets forth a method of calculating the actual growth in

emissions due to growth in VMT. Essentially, the st ate would compare projected

attainment year emissions assuming no new control measures and no VMT growth with

projected actual attainment year emissions (including new control measures and VMT

growth). If the latter number is smaller than the former, no a dditional TCMs or TCSs

would be required. If additional TCMs and TCSs are required, they should be clearly

identified and distinguished from the measures included in the initial calculations for the

base year and the three scenarios iden tified for the att ainment year.

In addition, the guidance recommends that the base year to be used in the

demonstration be the base year used in the attainment demonstration for the ozone

standard. This update includes a VMT offset demons tration in accordance with

U.S. EPA ’s new guidance for the 8

- hour ozone requirements. To address U.S. EPA’s

guidance on the base year, 2002 is used as the base year for the 1997 8

- hour standard.

Transportation Control Strategies and Transportation Control Measures

By listing them separatel y, section 182(d)(1)(A) of the Act differentiates between TCS s

and TCM s , and thus provides for a wide range of strategies and measures as options to

offset increased emissions from growth in VMT

. In addition, the example TCMs listed in

section 108(f)(1)(A ) of the Act include measures that reduce emissions by reducing

VMT, reducing tailpipe emissions, and removing dirtier vehicles from the fleet.

California’s motor vehicle control program includes a variety of strategies and measures

including new engine s tandards and in

- use programs (e.g., smog check, vehicle scrap,

fleet rules, and idling restrictions). The Southern California Association of Governments

(SCAG) has also developed a number of TCMs to provide emission reductions.

Based on the provisions i n s ection 182(d)(1)(A) of the Act and the clarifications provided

in the U.S. EPA guidance, any combination of TCSs and TCMs may be used to meet

the requirement to offset growth in emissions resulting from VMT growth. Since 1990

when this requirement was established, California has adopted a substantial number of

enforceable transportation strategies

– more than enough to meet the requirement to

offset the growt h in emissions from VMT growth. For the 1997 8

- hour standard offset

demonstration, 2002 control s are used as the base case control level since 2002 is the

base year of the SIP.

### E

- 3

A listing of the mobile source control programs adopted by the State since 1990 is

provided in Table E

- 4

. There are no TCMs in the SIP for the Coachella Valley and

Western Mojave Desert because upwind emissions from the South Coast Air Basin and

Ventura County largely influence air quality in both the Coachella Valley and Western

Mojave Desert . TCMs have been implemented by the SCAG in those upwind areas.

Emissions Due to Vehicle Miles Traveled Growth

As discussed above, the U.S. EPA guidance provides a recommended calculation

methodology that could be done to determine if sufficient TCSs and TCMs have been

adopted and implemented to offset the growth in em issions due solely to growth in

VMT. As such, any increase in emissions solely from VMT increases in the future

attainment year from the base year (assuming that there are no further motor vehicle

control programs implemented after the base year) would ne ed to be offset. In addition,

a calculation is needed to show the emissions levels if VMT had remained constant

from the base year to the future attainment year. As discussed earlier, a comparison of

the projected attainment year emissions assuming no ne w control measures and no

VMT growth with projected actual attainment year emissions (including new control

measures and VMT growth) would be made. If the latter number is smaller than the

former, no additional TCMs or TCSs would be required.

Methodology

The following calculations are based on the U.S. EPA guidance recommended

calculation methodology. F or the Coachella Valley and Western Mojave Desert 8

- hour

ozone standard, 2002 is the base year used for the attainment demonstration and 20 18

is the attain ment year.

Analysis Tool

This analysis uses California’s approved motor vehicle emissions model, EMFAC.

The EMFAC model estimates the emissions from two combustion processes: running

exhaust and start exhaust, and four evaporative processes: hot soak, running losse s,

diurnal, and resting losses.

Emissions from running exhaust, start exhaust, hot soak, and running losses are a

function of how much a vehicle is driven. Emissions from these processes are directly

related to VMT, trips, and starts. These processes are included in the calculation of the

emissions levels used in the VMT offset demonstration. Emissions from resting loss

and diurnal loss processes are not related to VMT, trips or vehicle starts and are not

included in the analysis because the se emissions occur regardless if the vehicle make s

a trip (i.e. a start) or not.

EMFAC combines trip

- based VMT from the regional transportation planning agencies,

starts data based on household travel surveys, and vehicle population data from the

### E

- 4

Departmen t of Motor Vehicles with corresponding emission rates to calculate

emissions. 4



### With the EMFAC model, the calculation of emissions growth and whether it is offset is

simplified to a comparison of future year emissions with “no growth” in VMT or new

control strategies to future emissions with VMT growth and new control strategies. This

follows U.S. EPA ’s 2012 guidance and is consistent with the Ninth Circuit’s

interpretati on of Act section 182(d)(1)(A).

The Advanced Clean Cars (ACC) regulations adopted by AR B in 2012 are not included

in EMFAC 2011. The output from EMFAC 2011 was adjusted off

- model to estimate the

benefits of the ACC regulations. No other off

- model adjustments were taken.

Step 2. Calculate three emissions levels in the attainment year.

For the attainment year,

(1) Calculate emissions level with the motor vehicle control program frozen at

2002 levels and with projected VMT, starts, and vehicle population for the

attainment year. This represents what the emissions in the attainment

year would have been if TCSs and TCMs had not been implemented after

2002;

(2) Calculate emissions level with the motor vehicle control program frozen at

2002 levels and assuming VMT, starts, and vehicle population do not

increase from 2002 levels; and

(3) Calculate an emissions level that represents emissions with full

implementation of all TCSs and TCMs since 2002 and which represents

the projected future year baseline emissions inventory using the VMT,

starts, and vehicle popu lation for the attainment year.

Calculation 1

. Calculate the emissions in the attainment year

assuming no new measures since the base y ear, and including

growth in vehicle miles traveled, starts, and vehicle population.

T o perform this calculation, ARB staff identified the on

- road motor vehicle control

programs adopted since 2002 and adjusted the EMFAC2011 results to reflect the

ROG emissions levels in 2018 without the benefits of the post

- 2002 control

programs. The projected ROG emissions for Coachella Valley and Western

Mojave Desert are 4 tons/da y and 9 tons/day, respectively.

Calculation 2. Calculate the emissions with no growt h in vehicle

miles traveled

, starts, or vehicle population

.

EMFAC2011 allows the user to input different VMT, starts, and vehicle population

than default. As such, for this calculation, the EMFAC 2011 model was run

without the benefit of the post 2002 co ntrol program for calendar year 2018 for

Coachella Valley with the 2002 level of VMT of 10

, 293 ,000 miles per day, the

2002 level of starts at 1,248,220 per day, and the 2002 level of population at

19 8

, 000 vehicles. The ROG emissions associated with 2002 V MT, starts, and

vehicle population are 3 tons/day. The EMFAC 2011 model was also run for

Western Mojave Desert without the benefit of the post 2002 control program for

calendar year 2018 with the 2002 level of VMT of 26,920,000 miles per day, the

2002 lev el of starts at 2,274,199 per day, and the 2002 level of population at

367,000 vehicles. The ROG emissions associated with 2002 VMT, starts, and

vehicle population are 7 tons/day.

As provided in the U.S. EPA guidance, to determine com pliance with the provisions of

the Act, the emissions levels calculated in Calculation 3 should be less than the

emissions levels in Calculation 2:

C oachella Valley ROG: 2 < 3 tons per day

Wester n Mojave Desert ROG: 6 < 7 tons per day

Summary

The previous sections provide an analysis to demonstrate complian ce with the

provisions of the Act. To further illustrate the demonstration, Figure 1 and 2 below show

graphically the emissions benefits of the motor vehicle control programs in offsetting

ROG emissions due to increased VMT, starts, and vehicle population in the Coachella

Valley and Western Mojave Desert, respectively, for the 1997 8

- hour ozone standard

(2002 base year). The left bar (in purple) shows the emissions in the base year with

base year controls. The three bars on the right in each figure show the emissions levels

in the attainment year for the three calculations identified above: the red bar shows

attainment year emissions with base year controls and attainment year VMT, starts, and

vehicle population, the green bar shows attainment year emiss ions with base year

controls, VMT, starts, and vehicle population, and the blue bar shows attainment year

emissions with attainment year controls, VMT, starts, and vehicle population. Based on

the U.S. EPA guidance, if the blue bar is lower than the green bar, then the identified

TCSs and TCMs are sufficient to offset the growth in emissions.
