Dear Mr. Blumenfeld:

We are transmitting our recommendations for area designations and boundaries under

the federal air quality standards for particulate matter 2.5 microns or less in diameter

(PM2.5) as requested in the U.S. Environmental Protection Agency (U.S. EPA)

memorandum of April 

### 16, 2013 from the Assistant Administrator to the Regional

Administrators.

PM2.5 Nonattainment Areas

We base our recommendations on ambient PM2.5 concentrations measured from 2010

through 2012 by over 90 Federal Reference Method (FRM) and Federal Equivalent

Method (FEM) monitors located throughout California. FEM data for both the

South Coast Air Basin and the San Diego Air Basin were excluded from this process as formally requested by the affected air districts and detailed in the accompanying staff

report.

The Air Resources Board (ARB) recommends that U.S. EPA designate the following

three areas as nonattainment for the revised PM2.5 annual standard of 12.0 tg/m 3

, with

the remaining areas of the State designated as unclassifiable/attainment:

• South Coast Air Basin.

• San Joaquin Valley Air Basin.

• Imperial County (partial).

As specified in the enclosed Staff Report, ARB staff recommends that the

nonattainment area boundaries coincide with the each area’s current PM2.5

nonattainment boundary.

The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption.

For a list of simple ways you can reduce demand and cut your energy costs, see our website: http:llwww.arb.ca.ov.

### Summary

On December 14

, 2012 , the U.S. Environmental Protection Agency ( U.S. EPA )

strengthened the annual National Ambient A ir Q uality S tandard (NAAQS or

standard ) for particulate matter 2.5 micrometers or less in diameter (PM 2.5 

### ) from

15.0 μ g/m 3 

### to 12.0 μ g/m 3



### . The State of California is required to submit area

designation recommendations and appropriate boundaries to U.S. EPA for this

standard by December 14

, 2013

. The purpose of this report is to share the

staff’s technical analysis and recommendations to be sent to U.S. EPA.

U.S. EPA will m ake final designations in Dece mber 2014.

California Air Resources Board ( ARB ) staff has performed an analysis to

determine appropriate designation areas throughout the S tate using criteria

outlined in the U.S. EPA’s guidance memorandum

. 1 

### Determination of

attainment/nonattainment is based on comparing a three

- year average of the

annual average concentration to the level of the standard. This is known as the

design value. These three

- year rolling averages are updated once the year’s

monito ring data is reviewed and certified.

Due to the success of ongoing programs, many California counties already meet

the 12.0 μ g/m 3 

### standard . B ased on 2010

- 2012 PM 2.5 

### air quality monitoring data

, the three areas that do not meet the standard are: South Coast Air Basin, San

Joaquin Valley and Imperial County. Staff is recommending that the b oundaries

for the 15.0 μ g/m 3 

### standard for the South Coast Air Basin and the San Joaquin

Valley be retained for the new standard. The recommended boundary fo r Imperial County is the same as the boundary for the 35 μ g/m 3 

### 24

- hour standard

. While U.S. EPA is expected to base final designations on 2011

- 2013 PM 2.5 

### data

, the attainment status is not expected to be different with the addition of 2013

data.

Air Quality Analysis

ARB maintains a comprehensive PM 2.5 

### monitoring network, including Federal

Reference Method (FRM) mass samplers, Federal Equivalent Method (FEM)

continuous mass samplers, and chemical speciation samplers. ARB staff use s

these monitoring da ta to determine PM 2.5 

### concentrations in relation to the federal

standard

. S peciation samplers are used to determine the nature of the PM 2.5 

### pollution and to assist in assessing the efficacy of emission reduction strategies

. ARB staff’s initial designation recommendations are based on ambient PM 2.5 

### concentrations measured from 2010 through 2012 by over 90 FRM/FEM

monitors , sited and operated in accordance with federal requirements, and

located throughout the S tate.

U.S. EPA allows for the excl usion of certain FEM data, if the data have compared

poorly with FRM data

, in accordance with the Particulate Matter NAAQS rule

### published o n January 15, 2013 2 

### and specific to the provisions detailed in

§58.10 (b)(13) and §58.11 (e)

. Consequently, formal requests were submitted to

the U.S. EPA by t he South Coast Air Quality Management District (South Coast

AQMD) 3 

### and the San Diego County Air Pollution Control District (San Diego

APCD) 4 

### to exclude the use of FEM data in comparison to the NAAQS due to

insuff icient comparability to collocated PM 2.5 

### monitors. In anticipation of U.S.

EPA granting this request, the data from these monitors were not used in

calculating the 2012 annual PM 2.5 

### design values.

The U.S. EPA’s guidance memorandum also states that air quality monitoring

data affected by exceptional events may be excluded from use in identifying a

violation if certain criteria are met

. The 2012 design values in this document do

not reflect the exclusion of impacts from exceptional events

, as these even ts

would not affect attainment status based on data for 2010 through 2012.

H owever, should this change with the addition of data for 2013

, ARB staff will

submit any required documentation to U.S. EPA in accordance with federal policy

on exceptional events prior to final designations

.

T he following ta ble provides the annual PM 2.5 

### design value for three air districts

with monitors violating the standard : South Coast AQMD, San Joaquin Valley Air

Pollution Control District (San Joaquin Valley APCD )

Boundar y Analysis

In California, if the pollution problem is regional in nature

, the primary

considerations for air quality planning are air basi n and air district boundaries

. Consistent with State law, California’s air basin boundaries were established

based on a scientific assessment of emission s

, geography

, and meteorology,

with consideration of political jurisdictions. Basin boundaries are formally

### adopted by ARB in regulation. Local a ir district s have been established

, and

their jurisdictions defined

, by State statute. ARB typically uses a combination of

air basin and a ir district lines to identify boundaries for areas that violate air

quality standards, with the exception of situations where a single city or

community has a unique air pollution problem distinct from the region.

The Clean Air Act requires that a nonat tainment area must include not only the

area that is violating the standard, but also nearby areas that contribute to

violation s . Accordingly, ARB’s recommended nonattainment boundaries are

sufficiently large to include both the violating and contributing areas

. U.S. EPA

guidance recommends that in making boundary recommendations for

nonattainment areas, s tates evaluate each area on a case

- by

- case basis in

consideration of the following five factors:

• Air quality data

• Emissions and emission

- related data

• Meteorology

• Geography/topography

• Jurisdictional boundaries

The boundaries already in existence for the 24

- hour PM 2.5 

### standard , and in the

case of the South Coast and San Joaquin Valley Air Basins, the previous annual

PM 2.5 

### standard , are t he result of exte nsive technical analyses, 5 

### and continue to

appropriately reflect conditions under the revised annual PM 2.5 

### standard

.

Designation Recommendations

After consideration of the five factors outlined in U.S. EPA’s guidance

memorandum

, ARB staff recommends the nonattainment area boundaries

outlined below.

Imperial County Air Pollution Control District

No portion of Imperial County was designated nonattainment for the previous

annual standard of 15 μ g/m 3 

### . In 2006, after extensive technical analysis,

U.S. EP A designated a portion of Imperial County as nonattainment of the

24

- hour PM 2.5 

### standard of 35 μ g/m 3 

### . Based on 2010

- 2012 monitoring data, only

one monitor in Imperial County is in nonattainment for the revised annual PM 2.5



### standard

, with a design value of 14.0 μ g/m 3



### . The violations of the PM 2.5 

### standard

are localized at the monitor at Calexico

, on the U.S.

– Mexico border, at the

southern end of Imperial County

. ARB staff’s assessment of air quality in the

region indicates the area would attain the PM 2.5 

### air quality standard but for

emissions emanating from outside of the United States , in particular, from the

5 Letter from James Goldstene, Executive Officer, ARB, to Wayne Nastri, Regional Administrator,

U.S. EPA , December 17, 2007, plus enclosures; Lett er from Wayne Nastri, Regional

Administrator, U.S. EPA, to Arnold Schwarzenegger, Governor, State of California,

August 18, 2008, plus enclosures; Letter from James Goldstene, Executive Officer, ARB, to

Wayne Nastri, Regional Administrator, U.S. EPA , October 15, 2008, plus enclosures.



### 3

### much larger adjacent city of Mexicali, Mexico. Consideration of U.S. EPA’s five

factors indicates that this international pollutant transport cont ributes to elevated

PM 2.5 

### levels at Calexico and, to a much lesser extent

, the urban area to the

north

. This analysis of the contribution of international transport to the annual

PM 2.5 

### standard is c onsistent with the assessment previously submitted for the

recently revised 24

- hour PM 2.5 

### standard and U.S. EPA’s extensive technical

analysis in support of the final designations

. 5 

### Consistent with the previous

assessment of the impacts of international pollutant transport on PM2.5 in

Imperial County, ARB re commends the annual PM 2.5 

### nonattainment area

coincide with the nonattainment area already in existence.

The recommended Imperial County PM 2.5 

### nonattainment area include s the urban

areas of Calexico, Brawley, El Centro, Holtville, Imperial, Seeley, and

Westmorland. The area is under the jurisdiction of the Imperial County Air

Pollution Control District. The official boundary is provided in Attachment 2

.

San Joaquin Valle y Air Basin

In 1997 , the San Joaquin Valley Air Basin (San Joaquin Valley) was designated

nonattainment of the annual PM 2.5 

### standard of 15.0 μ g/m 3 

### . Based on 2010

- 2012
monitoring data, the San Joaquin Valley remains in nonattainment of the revised

annual P M 2.5 

### standard with a design value of 16.0 μ g/m 3 

### measured at the Clovis

– N Villa Ave monitoring site. In addition to data recorded at the high site listed in

Table 1

, other monitors distributed throughout the San Joaquin Valley record

violat ions of the standard (Attachment 1). Consideration of U.S. EPA’s five

factors indicates broad regional contribution to elevated PM 2.5 

### levels and

supports the use of the air basin boundary which reflect s the regional nature of

PM 2.5 

### pollution in th i s area

. Consi stent with this recent analysis, the assessment

previously submitted for the recently revised 24

- hour PM 2.5 

### standard

, and U.S.

EPA’s extensive technical analysis in support of their final designations, 5 

### ARB

recommends the annual PM 2.5 

### nonattainment area coincide with the

nonattainment area already in existence.

The recommended San Joaquin Valley PM 2.5 

### nonattainment area consists of

San Joaquin, Stanislaus, Merced, Madera, Fresno, Kings, Tulare

, and Western

Kern Counties. The area is under the jurisdiction of the San Joaquin Valley Air

Pollution Control District. The official boundary is provided in Attachment 2.

South Coast Air Basin

In 1997 , the South Coast Air Basin (South Coast) was designated nonattainment

of the annual PM 2.5 

### standard of 15.0 μ g/m 3 

### . Based on 2010

- 2012 monitoring

data, the South Coast remains in nonattainment of the revised annual PM 2.5 

### standard with a design value of 15.2 μ g/m 3 

### measured at the Mira Loma

– Van Bure n monitoring site. In addition to data recorded at the high site listed in

Table 1

, other monitors distributed throughout the South Coast record violat ions

of the standard (Attachment 1). Consideration of U.S. EPA’s five factors

indicates broad regional contribution to elevated PM 2.5 

### levels and supports the

4

### use of the air basin boundary which reflect s the regional nature of PM 2.5 

### pollution

in th i s area . Consistent with this recent analysis, the assessment previously

submitted for the recently revised 24

- hour PM 2.5 

### standard, and U.S. EPA’s

extensive technical analysis in support of their final designations, 5 

### ARB

recommends the annual PM 2.5 

### nonattainment area coincide with the

nonattainment area already in existence.

The recommended South Coast PM 2.5 

### non attainment area includes Western

Los Angeles (excluding Catalina and San Clemente Islands), Orange,

Southwestern San Bernardino, and Western Riverside Counties. This area is

under the jurisdiction of the South Coast Air Quality Management District. The

o fficial boundary is provided in Attachmen t 2
