### 1.0 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 ( 40 CFR 58 .10) , to submit a n

Annual Monitoring Network report to the 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 repor t must be presented for a 30

- day public review period prior

to submittal to EPA. This report covers the period: January 1, 2010

- December 3 1

, 2010

.

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

Sacramento Co unty State and Local Air Monitoring sites (SLAMS)

, National Core ( NCore ) multi

pollutant monitoring stations , Speciated Trend Network (STN), Special Purpose Monitoring

(SPM), and Photochemical Assessment Monitoring (PAMS) sites, operated by our District an d

CARB, 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 F e d eral

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 incorp oration in to the ambient air monitoring network. This analysis is due

July 1, 2010.

### 2.0 Overview of Network Operations

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,

C alifornia 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 2 5 th 

### largest MSA in the USA

, based upon population , with a population of 2. 1 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 (S FNA)

. This

network plan focuses on the monitors that are operated within Sacramento County. For details

on the monitors operated in the other counties within the SFNA , please refer to the Annual

Monitoring Network Report for Small Districts in California dated May 2010 prepared by the

California Air Resources Board ( http://www.arb.ca.gov/aqd/amnr/smnetrpt10.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 County as

unclassified for the 2008 Federal Pb standard. Final EPA designation as attainment or

unclassified for the 2008 Pb standard is due in O ctober 15, 2011

.

T he 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 not ification , 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

below identifies the locations of curr ent air monitoring stations within Sacramento County,

whether they are a SLAMS site or not. Map 1 shows the approximate location of each

monitoring station in Sacramento County. Table 1 gives detailed information of each station,

including location, AQS ID, pollutants monitored and designates whether it is a SLAMS site.

2.1 Monitoring Objectives 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 emission

strategy development; and 3) support air pollution research studies. T o support these

monitoring objectives there are a variety of types of monitoring sites including sites located to

determine the highest pollutant concentration, the representative concentrations in areas of

high population density , the impact of major poll ution emissions sources, the general

background concentration levels, the extent of pollutant transport, and impacts on visibility,

vegetation, 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 location of the site with respect to the pollutant sources. It

estimates the size of the area surrounding the monitoring s ite that experiences uniform

pollutant concentrations. Table 2 shows the different types of site and the appropriate spatial

scale. Table 3 shows each of the monitoring sites in Sacramento County and its criteria

pollutant monitoring objective s and spati al 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

 Neighborh ood Scale

– An area with dimensions in the 0.5 to 4.0 kilometer range

 Urban Scale

– Citywide pollutant conditions with dimensions r anging 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

### 3.0 Minimum Monitoring Requirements

Sacramento County is within the Sacramento

- Arden Arcade

- Roseville MSA as discussed in

Section 2.0. The minimum number of monitors for each pollutant is based on the MSA

population as described in 40 CFR 58 Appendix D. The Sacramento

- Arden Arcade

- Roseville

MSA has a popul ation of 2. 1 million. Th e monitoring network within the MSA exceeds the

minimum monitoring requirements for all criteria pollutants. Details are provided in table 4

. For current National Ambient Air Quality Standards, please refer to the NAAQS Table

### 4.0 Recent or Proposed Modifications to the Network

Sacramento

- Del Paso Manor

In July 2010

, the District received approval from EPA and relocated the PM 10 

### TEOM sampler to

Sacramento

- Goldenland Ct. to free up instrument rack space for NCore instrumentations.

EPA approved Sacramento

- Del Paso Manor as an NCore multi

- pollutant monitoring station for

this MSA in 2009. Thus

, the District installed a NO

y 

### analyzer, SO 2 

### trace level analyzer, CO trace

level analyzer, and low volume PM 10 

### FRM sample in 2010 . The low volume PM 10 

### FRM sampler

will serve as a PM 10

- 2.5 

### (coarse) and non

- source oriented Pb

- PM 10 

### monitor. The gaseous

analyzers are operational beginni ng in July 2011.

Due to the r evisions to the Lead Ambi ent Air Monitoring Requirement (Docket ID No. EPA

– HQ

–

OAR

– 2006

– 0735), effective January 26, 2011

, the Pb

- PM 10 

### monitor must be operational by

December 27, 2011.

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 . T he District also

may cease operation of the Pb

- PM 10 

### sampler when the Pb

- TSP sampler becomes operational.

Due to the revised SO 2 

### NAAQS, a plan for establishing the required SO 2 

### monitoring sites shall be

submitted to EPA by July 1, 2011, as a part of the An nual Network Plan. O ne SO 2 

### monitor is

required in this CBSA . This requirement is met using the trace level SO 2 

### FRM monitor operating

at Del Paso Manor NCore station

.

The revised SO 2 

### NAAQS introduced a requirement for the minimum number of SO 2 

### analyzers

within a CBSA, via a Population

- Weight Emission Index (PWEI). The PWEI for the Sacramento

CBSA is 1,476 millions of people

- tons per year (CBSA population estimate is 2,127,355 as of

7/1/2000 and annual CBSA SO 2 

### emission is 694 tons per year). If the PWEI is  5,000 and

 1 0, 000, then a minimum of one SO 2 

### analyzer would be required in this CBSA.

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. Termination of

this instrument would free up rooftop space for future NCore instrumentations.

Sacramento

- El Camino/Watt

In September 2011, EPA approved t he District ’s site termination request due to a

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

monitoring station . The site termination is contingent on the construction project obtaining

funding and being app roved to proceed. The District is evaluating to relocate the CO monitor

to one of the required NO 2 

### near

- roadway site s that must be operational no later than January

1, 2013. The District will comply with monitoring requirements as promulgated in the fina l rule

of the CO NAAQS review.

### - 11

-

Sacramento

- Goldenland Ct

As mention under Sacramento

- Del Paso Manor, a PM 10 

### TEOM was relocated from Del Paso

Manor in July 2010

.

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

### SSI at this site.

Termination of these monitors will free up resources necessary for operation of the future NO 2



### near

- roadway sites. The District will comply with monitoring requirements a s promulgated in

the final rule of the CO NAAQS.

North Highlands

- Blackfoot Way

EPA approved the request for SO 2 

### analyzer termination on November 3, 2010

. Thus, the

District terminated the SO 2 

### monitoring at this location

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

### SSI sampler.

The District is eval uating shutting down the O 3 

### , CO, and NO 2 

### at this site. This site is a redundant

air monitoring site and was or i ginally sited to support a proposed power plant project at

McClellan AFB . Staff resources used to support this air monitoring site would be use d to

support the new NO 2 

### near roadway monitoring site s , which are required to be operational by

January 1, 2013

. The District will comply with monitoring requirements as promulgated in the

current CO NAAQS review.

Sacramento

- Stockton Blvd

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

### SSI, PM 10 

### TEOM, 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. The TEOM data is not usabl e for forecasting or analysis

due to negative bias during the winter time 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.

Sacramento

- Sloughhouse Rd

The District requested the site own er to remove a nearby tree, in order to comply with

Appendix E, 40 CFR 58. The tree was removed in May 2011. Now that this site satisfies SLAMS

probe siting criteria, the classification of the O 3 

### monitor was changed from SPM to SLAMS.

### - 12

-



### 5 .0 Process to review changes to PM 2.5 

### Monitoring Network

40 CFR 58 requires that this Annual Monitoring Plan 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 th e 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 as 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.

For comparison purposes, the number of PM 2.5 

### monitors by area and population has been

inc luded. 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 wi ll 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.



### 6.0 Data Submission Requirements

 2010 Precision/Accuracy reports submitted to AQS: Spring 2011

 2010 Annual data certification submitted: May 2011 (by CARB)



### 7 .0 Review of existing SMAQMD /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 geograph ic area and population in

several air districts in California is shown in the table below.

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 squa re mile.

However, caution should be used when doing these types of comparisons, 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) c ompared to the

Sacramento MSA, but Bay Area has a higher population 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 J oaquin Valley has the typical PM 2.5 

### sources of motor vehicles 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 loca l/regional monitoring needs, depending upon the unique

features and needs of that District.

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

to the north

.

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

original site initiation reports fi led in the late 1980s. The old site was relocated since nearby

trees were a flow obstacle.

### B .7 North Highlands

- Blackfoot

North Highlands

- Blackfoot has been in existence since 1979. It is a Special Purpose Monitoring

site for O 3 

### , CO, and NO 2 

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

- 10 SSI. SO 2 

### was terminated in late

2010

.

Th is en tire 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 McCllean Air Force Base, which was 3 miles southwest of the site

. The purposed power plant

project was can celed during the early 1980’s

.

During an annual review of SLAMS network design in the mid

- 1990s

, the District needed addition al

NAMS sites for SO2 and PM 10 

### to meet minimum monitoring requirements. Thus, the designation of

the SO2 and PM 10 

### monitors at North Highlands was changed from SPM to NAMS.

### B.8 Sloughhouse

Located in a rural area 16.5 miles southwest of Downtown Sacramento, t his site measures O 3 

### ,

w ind d irection, w ind s peed , and PM 2.5



### .

Sloughhouse was established in 1997 as a seasonal (April

- October) O 3 

### special purpose

monitoring site to measure elevated afternoon O 3 

### concentrations, under northwesterly winds,

in support of the District's summer Spare the Air (O 3 

### episodic control measure) program. It was

sited to cover “data gaps” in the O 3 

### monitoring network, which is still used for forecasting

summer AQI levels.

A tree existed within 10 meters southeast of the O 3 

### inlet. Although this tree was downwind of

the sample inlet under prevailing wind, the District requested removal. The land owner

removed the tree in May 2011. Since the site now co mplies with Appendix E (Probe and

Monitoring Path Siting Criteria) , the O 3 

### monitor was re

- classified from SPM to SLAMS.

Since November 2008, seasonal (November

- February) monitoring for PM 2.5 

### is conducted at this

site. A special purpose PM 2.5 

### E

- BAM monito r collects data in support of the South Sacramento

County Winter PM 2.5 

### study. This study has been extended, due to the extremely low data

capture rates during the 2008 and 2009 winter seasons.
