1. I NTRODUCTION

State and Local agencies that conduct ambient air monitoring for regulatory purposes

are required, by Title 40, Code of Federal Regulations, Part 58.10 , to submit an Annual

Monitoring Network Plan to the U.S. Environmental Protection Agency ( EPA ) , no later

than July 1 st 

### , each year, starting July 1, 2007. The report must contain specific

monitoring network information and the report must be presented for a 30

- day publ ic

review period prior to submittal to EPA. This report covers the period: January 1, 2011

- December 31, 2011.

The primary purpose of this ambient air monitoring network report is to document the

existing Sacramento County State and Local Air Monitoring s ites (SLAMS) , National

Core (NCore) multi

- pollutant monitoring stations, Chemical Speciation Network (CSN),

Special Purpose Monitoring (SPM), and Photochemical Assessment Monitoring (PAMS)

sites, operated by our District and California Air Resources Board (C ARB ) , and to show

that the ambient air monitoring network meets the requirements of 40 CFR 58, including

Appendix A, C, D, and E, where applicable. The report will include the Federal

Reference Method ( FRM )

, Federal Equivalent Method ( FEM ) , and Approved Regional

Method ( ARM ) monitors. Though not required by 40 CFR Part 58, the report also

discuss es additional SPM monitoring instrumentation being operated, such as

Aethalometer s and Nephelometer s, and surface/upper air meteorological sensors

required for the PAMS program. The secondary purpose of this report is to discuss

proposed changes (additions, relocations, and terminations of non

- SPM monitors) in the

ambient air monitoring network that may be proposed to occur within an 18 month

period following su bmittal of this report.

This report is not an "in depth" analysis of the local a ir m onitoring n etwork design. An in

depth analysis of the monitoring network is required every 5 years to determine, at a

minimum, if the network meets the monitoring objectiv es defined in 40 CFR Part 58

Appendix D, whether new sites are needed, whether existing sites are no longer

needed, and whether new technologies are appropriate for incorporation in to the

ambient air monitoring network.

2. OVERVIEW OF NETWORK OPERATION S

The County of Sacramento is located in the middle of California's Central Valley, at the

southern end of the Sacramento Valley. Sacramento County has a population of 1.4

million 1 

### . Sacramento County is the most populated part of the Sacramento

-- Arden

Arcade

-- Roseville, California Metropolitan Statistical area (MSA) which includes the

western sections of Placer and El Dorado County, Yolo County, and parts of Solano and

Sutter Counties. The Sacramento MSA is the 24 th 

### largest MSA in the USA by

population , with 2.2 million people 1 

### . The Sacramento MSA is a non

- attainment area for

the Federal 8 hr averaged O 3 

### standard and is referred to as the Sacramento Federal

Nonattainment Area (SFNA). This network plan focuses on the monitors that are

operated within Sacramento County. For details on the monitors operated in the other

1 

### 2010 U.S. Census

### 7

counties within the SFNA, please refer to the Annual Monitoring Network Report for

Small Districts in Californ ia dated June 2011 prepared by CARB

( http://www.arb.ca.gov/aqd/amnr/smnetrpt11.pdf ).

Sacramento County is a nonattainment area for the Federal O 3 

### and PM 2.5 

### standards.

Sacramento County is in attainment for the Federal CO, NO 2 

### , and SO 2 

### standards. It

has attained the Federal PM 10 

### standard and has requested resignation to attainment

status. Sacramento County is a non

- attainment area for the California O 3 

### , PM 10 

### , and

PM 2.5 

### health standards. The California Air Resources Board recommended that EPA

designate Sacramento Cou nty as unclassified for the 2008 Federal Pb standard.

The primary focus of the current ambient air monitoring network is the collection of O 3 

### and photochemical pollutant precursors such as NO X 

### and VOC, and PM 2.5 

### data to

support SIP development, attainment /non

- attainment decisions, public notification, and

data for air quality modeling efforts. Sacramento is one of 24 areas in the nation that

are required to operate PAMS. Sacramento is one of the 54 areas in the US, with a

PM 2.5 

### CSN trend site. The map b elow identifies the locations of current air monitoring

stations within Sacramento County, whether they are a SLAMS site or not. Figure 2

- 1

shows the approximate location of each monitoring station in Sacramento County.

Table 2

- 1 gives detailed informati on of each station, including location, AQS ID,

pollutants monitored and designates whether it is a SLAMS site.

2.1 MONITORING OBJECTIVE S AND SPATIAL SCALES

The basic three monitoring objectives are to: 1) provide air pollution data to the general

public in a timely manner; 2) support compliance with ambient quality standards and

emissions strategy development; and 3) support air pollution research studies. To

support these monitoring objectives there are a variety of types of monitoring sites

including sites located to determine the highest poll utant concentration, the

representative concentrations in areas of high population density, the impact of major

pollution emissions sources, the general background concentration levels, the extent of

pollutant transport, and impacts on visibility, vegetati on, and other welfare

- based

impacts.

The physical sitting of an air monitoring station must achieve a spatial scale of

representativeness that is consistent with the monitoring objective of the monitor. The

spatial scale results from the physical locatio n of the site with respect to the pollutant

sources. It estimates the size of the area surrounding the monitoring site that

experiences uniform pollutant concentrations. Table 2

- 2 shows the different types of

site and the appropriate spatial scale. Tabl e 2

- 3 shows each of the monitoring sites in

Sacramento County and its criteria pollutant monitoring objectives and spatial scales.

The categories of spatial scale are:

 Microscale

– An area of uniform pollutant concentration ranging from several

meters up to 100 meters

 Middle Scale

– Uniform pollutant concentrations in an area of about 100 meters

to 0.5 kilometers

 Neighborhood Scale

– An area with dimensions in the 0.5 to 4.0 kilometer

range

 Urban Scale

– Citywide pollutant conditions with dimensions rangin g from 4 to

50 kilometers

 Regional Scale

– A large area, usually rural, of the same general geography and

without large sources that extends from tens to hundreds of kilometers

. MINIMUM MONITORING R EQUIREMENTS

Sacramento County is within the Sacramento

- Arden Arcade

- Roseville MSA as

discussed in Section 2. The minimum number of monitors for each pollutant is based

on the MSA population as desc ribed in 40 CFR 58 Appendix D. For current National

Ambient Air Quality Standards, please refer to the NAAQS Table

( http://epa.gov/air/criteria.html ).

Details of the minimum monitoring requirements of all criteria pollutants are provided in

table s 3

- 1 , 3

- 2, and 3

- 3. M inimum monitoring requirement is based on the population of

Sacramento

- Arden Arcade

- R oseville MSA, which is 2.2 million according to 2010 U.S.

Census . Sacramento

- Arden Arcade

- Roseville MSA is composed of El Dorado, Placer,

Sacramento, and Yolo Counties.

. RECENT AND PROPOSED MODIFICATIONS TO THE NETWORK

Sacramento

- Bercut Dr. (Proposed Site)

Contingent on approval from the EPA, Bercut Dr. is tentatively selected as the near

road NO 2 

### site required by the new NO 2 

### monitoring requirement. Appendix C to this

network plan discusses site selection criteria and the rationale for locating the near

- roa d

NO 2 

### station at this location.

As per Appendix D to 40 CFR Part 58, this station will monitor the required pollutants

– NO 2 

### and CO

– as well as optional pollutants and meteorological parameters

– black

carbon, wind direction, wind speed, temperature, and relative humidity. This air

monitoring station was required to be installed an d operational by January 1, 2013

. However, EPA a dvised that they plan to revise 40 CFR 58 to extend the deadline

January 1, 2014, for CBSA with population greater than 1 million , during the 2012 Air

Quality Conference

.

Elk Grove

- Bruceville Rd.

The District is considering to discontinue the speciated V OC measurement. As per

Appendix D to 40 CFR Part 58, only two speciated VOC measurement sites are

required per PAMS network area

. Sacramento

- Del Paso Manor (type II PAMS) and

Folsom

- Natoma St. (type III PAMS) satisfy this requirement. Speciated VOC

meas urement collected at this site is insignificant due to its low, background

concentration.

Sacramento

- Del Paso Manor

In March 2012, the District was added to EPA’s national lead analysis contract. Thus,

lead sampling began in April 2012 using with a PM 1 0 

### low volume sampler. As per 40

CFR 58, Appendix C, Section 2.10.2, the District will install and operate a Pb

- TSP

sampler at Sacramento

- Del Paso Manor within six months, i f the maximum Pb

- PM 10



### three

- month arithmetic mean concentration is greater than or equal to 0.10 ug/m3 . The

District also may cease operation of the Pb

- PM 10 

### sampler when the Pb

- TSP sampler

becomes operational.

The District plans to replace the existing non

- FEM PM 2.5 

### BAM monitor with an FEM by

November 1, 2012. This FEM monitor will operate continuously and thus satisfy the

sampling requirement in 40 CFR 58.12(d)

. The non

- FEM monitor will be relocated to

Sloughhouse.

The District is evaluating to shut down the Nephelometer. It is a PM related instrument

installed in 1999 for California Regional Particulate Air Quality Study. After the study

ended, the monitor was not removed and became a special purpose monitor in 2001.

### 16



## Sacramento

- El Camino/Watt

In September 2011, EPA approved the District’s site terminatio n request due to a

street/sidewalk improvement project in 2012 that requires termination or relocation of

this air monitoring station. The termination process was postponed, as the

street/sidewalk project was delayed until April 2013. This site will be t erminated in early

2013 when the project proceeds.

Sacramento

- Goldenland Ct

The District is evaluating to terminate this site. Sacramento

- Goldenland Ct. is a

redundant secondary type II PAMS , as nearby Sacramento

- Del Paso Manor is a

primary type II PAMS that measures a full suite of VOC

. Furthermore, preliminary

analysis shows this site does not measure the highest concentration of criteria

pollutants. If this site is terminated, there are still enough number of monitors within this

CBSA to satisfy the monitoring requirement in Appendix D to 40 CFR Part 58.

North Highlands

- Blackfoot Way

The District is considering to reorganize this site. North Highland

- Blackfoot Way was

originally sited to support a proposed power plant project at McClellan AFB , which was

canceled during the early 1980s. The District is considering to request approval for

termination of PM 10 

### SSI sampler. Also, the district is evaluating to adapt a seasonal

sampling sch edule for O 3 

### and CO. Staff resource used to support this air monitoring

site would reassigned to support the new NO 2 

### near roadway monitoring sites.

Sacramento Health Dept.

- Stockton Blvd.

The District will submit a request for termination of the PM 10 

### T EOM and PM 2.5 

### FRM at

this site. The PM 10 

### SSI is not necessary, as the remaining number of SSI samplers is

more than the required number of SSI samplers, etc. The TEOM data is not usable for

forecasting or analysis due to negative bias during the winter t ime when there is wood

combustion. The PM 2.5 

### FRM is redundant, as it collects the same PM 2.5 

### data as the

nearby T St site.

Sloughhouse

A non

- FEM PM 2.5 

### BAM monitor will be relocated from Sacramento

- Del Paso manor in

November 2012. It will replace the existing PM 2.5 

### E

- BAM (SPM).

5. PM COLLOCATION REQUI REMENT

Quality Assurance Requirements for SLAMS found in Appendix A to 40 CFR Part 58

requires colloc ation for PM 10 

### , PM 2.5 

### FRM and FEM

, and PM 10

- 2.5 

### monitors . Section 3 in

the appendix states that each method within a ―primary quality assurance organization

(PQAO) must have 15 percent of the monitors collocated.‖

### 17

SMAQMD is a small air quality management district and does not maintain a PQAO

. Collocated monitors operated by SMAQMD are part of the CARB PQAO . Currently,

PM 2.5 

### FRM and PM 10 

### FRM monitors at Sacramento

- Del Paso Manor are collocated.

For complete details on PM collocation, please refer to the Section 6, Required Quality

Assurance of the Monitoring Program, in the Annual Monitoring Network Report for

Small Districts in California dated June 2011 prepared by CARB

( http://www.arb.ca.go v/aqd/amnr/smnetrpt11.pdf ).

. PROCESS TO REVIEW CH ANGES TO PM 2.5 

### MONITORING NETWORK

40 CFR Part 58 requires that this Annual Monitoring Plan to ― document how State and

Local Agencies provide for the review of changes to a PM 2.5 

### monitoring network that

impact the location of a violating PM 2.5 

### monitor or the creation/change to a community

monitoring zone, including a description of the proposed use of spatial averaging for

purposes of making comparisons to the annual PM 2.5 

### NAAQS a s set forth in Appendix N

to Part 58 in 40 CFR 58. The affected State or local agency must document the

process for obtaining public comment and include any comments received through the

public notification process within their submitted plan. ‖ Note that spatial averaging does

not apply in California because the state and local air monitoring districts collectively

elected not to establish community monitoring zone in the 1990s

.

An informational comparison, not required by air monitoring regulation, on t he number

of PM 2.5 

### monitors by area and population has been included. The analysis can be

found in Appendix A.

The general process for any proposed change to the monitoring network is that the

proposed change is discussed in this Annual Monitoring Plan. Then, during spring,

each year, this Annual Monitoring Plan will be sent by SMAQMD to CARB/TSD for

review and comment. Prior to June 1, each year, this report will be posted to our

District Website for no less than 30 day s , for public review and comment. During late

June, each year, the finalized Annual Monitoring Plan and comments on the Plan will be

forwarded to EPA

- Region IX, prior to the July 1 deadline.

. REVIEW OF EXISTING S MAQMD /CARB AIR MONITORING SITES

For each monitor at each monitoring site, the tables in Appendix B were used to

determine if each monitor meets 40 CFR 5 8 requirements, including Appendix A (QA

Requirements), C (FRM/FEM/ARM Requirements), D (Network Design Criteria), and E

(Probe Sitting Criteria), when applicable. The SMAQMD ambient air monitoring

network meets the requirements of 40 CFR 58 including Appendix A, C, D, and E.

A PPENDIX A

- COMPARISON OF NUMBER OF PM2.5 MONITORS BY AREA AND

POPULATION

The Sacramento MSA has a total of 1 6 PM2.5 monitors: 5 FRM, 9 BAM, and 2 SASS

monitor. 8 of the 1 6 PM 2.5 

### monitors are located in areas of high population density to

monitor for population exposure.

To illustrate how the Sacramento MSA compares to other air districts in terms of

monitoring PM 2.5 

### , a comparison of the number of PM 2.5 

### monitors by geographic area

and population in several air districts in California is s hown in the table below.

San Joaquin

Valley 25,000 3. 9 26 1 per 150,000 1 per 962

The numbers of PM 2.5 

### monitors per person show that the Sacramento MSA has a higher

than average number of monitors per person. The numbers of PM 2.5 

### monitors per

square mile show that the Sacramento MSA has a higher than average number of

monitors per square mile.

However, caution should be used when doing these types of co mparisons, as these four

Districts have different ratios of urbanized area vs. rural areas and rural vs. urban

population, etc. For example, Bay Area has a similar size (number of square miles)

compared to the Sacramento MSA, but Bay Area has a higher pop ulation density per

square mile, in the urbanized areas. San Joaquin Valley has a highest amount of area,

more rural population, and lowest population density per square mile. In addition, San

Joaquin Valley has the typical PM 2.5 

### sources of motor vehicle s and residential wood

combustion, but it also has agricultural sources of PM 2.5 

### . Thus, the size of a monitoring

network is largely determined by the number of monitors needed to satisfy the

local/regional monitoring needs, depending upon the unique featu res and needs of that

District.

- CURRENT DETAILED SIT E INFORMATION

B.1 SACRAMENTO

- BRANCH CENTER #2

Sacramento

- Branch Center #2 is a PM 10 

### SSI site. This site was established

, in

early 2006

, to replace the former Sacramento

- Branch Center site , which was

approximately one

- quarter mile to the north

.

The objective of this site is to measure the representative concentration, as

documented in the original site initiation reports filed in the late 1980s. The old

site was relocated since nearby trees were a flow obstacle.

### , CO, and NO 2 

### . This site is a SLAMS site for PM

10 SSI. SO 2 

### was terminated in late 2010.

This entire site was designated as SPM upon its establishment. The original site

objective was to collect data in support of a proposed power plant project

(Prevention of Significant Deterioration) at McClellan Air Force Base, which was

located 3 miles southwest of the site. The purposed power plant project was

canceled during the early 1980’s. The Air Force Base was closed in 2001.

During an annual review of network design in the mid

- 1990s, the District needed

additional NAMS sites for SO 2 

### and PM 10 

### to meet minimum monitoring

requirements. Thus, the designation of the SO 2 

### and PM 10 

### monitors at North

Highlands was changed from SPM to NAMS , which is now categorized as

A PPENDIX C

– NEAR

- ROAD NO 2 

### MONITORING

Introduction

In 2010, U.S. EPA promulgated new nitrogen dioxide (NO 2 

### ) monitoring requirements.

Local agencies are required to install and operate new near

- road monitoring stations

where hour ly maximum NO 2 

### emissions are expected. The Sacramento

— Arden

Arcade

— Roseville CBSA is required to have one near

- road NO 2 

### monitoring site as per

population and traffic criteria given in Appendix D to Part 58 in Title 40, Code of Federal

Regulation. The nea r

- road NO 2 

### monitoring site must be operational by January 1, 2013

as this CBSA MSA is in phase one of U.S. EPA’s Build and Hold plan. Recently, the

EPA postponed the operational deadline to January 1, 2014.

To determine the location with the maximum NO 2 

### emissions, a number of potential

locations were reviewed. Each of these locations was reviewed according to the

guidelines provided by U.S. EPA in the Near

- Road NO 2 

### Technical Assistance

Document (TAD). For example, AADT, number of heavy duty trucks, site

characteristics, and other logical issues are among the factors considered. The final

site selection meets the probe and siting criteria provided in Appendix D and E to 40

CFR Part 58. T his appendix explains the reasons for selecting Bercut Dr. as the

c andidate near

- road NO 2 

### monitoring site for this CBSA.

Traffic Data

Bercut Dr. would monitor NO 2 

### emissions from Interstate 5. The 150 block of Bercut Dr.

is located north of I Street exit on Interstate 5 (ahead leg of postmile 23.799), which is

less than one mile northeast of Downtown Sacramento. Interstate 5 is a major highway

that runs parallel t o the West Coast. In addition to linking with two regional highways, it

also links with Interstate 80, a transcontinental highway. Figure C

- 1 shows the locations

of top potential sites and highways in the region. According to the 2010 latest statistics

maintained by the Traffic Data Branch of California Department of Transportation

(―Caltrans‖), AADT on this targeted roadway is 186,000, of which 18,000 is heavy duty

truck traffic.

Although AADT at the Bercut Dr. site ranks #9 in the region, it ranks # 1 in terms of fleet

equivalent (FE) AADT. FE AADT is a quantitative way to compare NO 2 

### emissions

between roadways with different fleet mix. It is calculated with the heavy duty trucks vs.

non

- heavy duty vehicles emissions ratio. According to the EMissio n FACtors (EMFAC

2011 ) model developed by California Air Resource Board in 2011 , heavy duty trucks

and non

- heavy duty vehicles produce 9.65 and 0. 562 oz of NOx per vehicle per day,

respectively, for scenario year 2010 in Sacramento County. The emission ra tio is

calculated and rounded to 17 . At this ratio, the Bercut Dr. site is estimated to have 17%

more NO 2 

### emissions than the next highest location. If the national default emission

ratio, 10, is used to calculate the FE AADT, this site would still rank t he highest in FE

AADT, which is 16% more emissions than the next highest location.

### 60

Level of service (LOS) is another important factor considered. In the Transportation

Corridor Concept Report (TCCR) prepared by Caltrans in 2010, LOS on Interstate 5

nor th of I Street is rated ―F‖, the most congested condition. In April 2012, Sacramento

Council of Government, the regional transportation project coordinator , adopted future

construction project s in its Metropolitan Transportation Plan 2035 . The plan inclu des

the construction of two high occupancy vehicle lanes, one in each direction, north of I

St. on Interstate 5 by 2035. Despite the additional lanes, the TCCR forecasts the LOS

to remain at ―F‖ for the next twenty years.

Table C

- 1 details the AADT, flee t equivalent AADT, its ranking, and level of service

(LOS) of the top ranking sites in this CBSA. For brevity, only potential sites among the

highest ranked AADT or FE AADT are listed. Table C

Physical Considerations for the Selected Site

Bercut Dr. Site is selected partly for its site characteristics. According to the Near

- Road

NO 2 

### TAD, there are four components to physical site characteristics to consider:

roadway design, roadside structure, terrain, and meteorology. Each of these

components may have desirable or undesirable attributes that alter NO 2 

### concentration

captured. The ch aracteristics of Bercut Dr. Site are listed below.

 Roadway Design

– Interstate 5, north of I St., is elevated and can be divided into

two portions: bridge and solid fill. The Bercut Dr. site is located next to the

elevated roadway with solid fill and is 250 m away from the bridge portion to

avoid enhanced dispersion effect. Maximum NO 2 

### can be captured at this

location for two reasons. First, the elevated roadway, approximately 5 m above

surrounding ground level, with solid fill has a similar emissions p rofile as a flat

roadway, which allows direct sampling. Also, the inlet probe will be placed

slightly above roadway level, at 6 m, to minimize sample dispersion. At this

height placement, the inlet probe also meets the Probe and Monitoring Path

Siting Cr iteria as specified in 40 CFR Part 58.

 Roadside structure

– This portion of Interstate 5 does not have obstructions (i.e.,

sound wall) that funnels NO 2 

### downwind and prevents the capture of the highest

NO 2 

### concentration. The District is working with Caltr ans to remove short

vegetation along the roadway to minimize any adsorption or reaction effect on

NO 2



### .

 Terrain

– Sacramento is located in a flat valley. Terrain does not present a

challenge.

 Meteorology

– According to meteorological data observed at an airport five miles

south of Bercut Dr., Sacramento Executive Airport, prevailing wind is at this

location from the south

- southwest. Hence, the station would be downwind of

Interstate 5.

Bercut Dr. Site has no undesirable attributes that would decrease the maximum NO 2 

### captured. Electric power and phone service are also readily accessible. The site can

also be easily accessed by a site operator. The District is currently working with the

land owner to draft a lease agreement.

The sampling inlet probe wil l be placed approximately 20 m from the closest highway

lane. This is as close as practical due to the obstruction of the slope of the solid

- fill,

elevated roadway and a drainage canal that is parallel to the highway. The probe

placement meets the recomm endation provided in the Near

- Road NO 2 

### TAD as well as

the Near

- Road NO 2 

### Siting Criteria in Appendix E to 40 CFR, Part 58.

Table C

- 3 lists the site characteristics of among top ranking sites.

### 65

Population Exposure

As instructed by the TAD, Bercut Dr. Sit e was selected despite having limited population

exposure to NO 2



### . The TAD states that population exposure should only be used if two

identical sites existed. Currently, most of area near Bercut Dr. is not developed for

residential housing. Future urban development would likely increase population

exposure, due to planned high density housing and commercial retail.

Conclusion

The Bercut Dr. site has the highest number of heavy duty truck traffic in the region that

contributes to the highest FE

- AADT and emissions compared to other near

- road

locations. Because of the site characteristic at Bercut Dr., it allows direct sampling of

NO 2 

### emissions Therefore, this site is likely to measure the highest NO 2
