1.0 Introduction

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 an

Annual Monitoring Network report to the Environmental Protection Agency (EPA), no later 

than July 1st, each year, starting July 1, 2007. The report must contain specific monitoring 

network information and the report must be presented for a 30-day public review period prior 

to submittal to EPA. This report covers the period: January 1, 2010-December 31, 2010.

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

Sacramento County State and Local Air Monitoring sites (SLAMS), National Core (NCore) multipollutant monitoring stations, Speciated Trend Network (STN), Special Purpose Monitoring 

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

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 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 discusses additional 

SPM monitoring instrumentation being operated, such as Aethalometers and Nephelometers, 

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 submittal of this report.

This report is not an "in depth" analysis of the local air monitoring network 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 objectives 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. 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 million1. 

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 25

th largest MSA in the USA, based upon population, with a population of 2.1 million 

people1. The Sacramento MSA is a non-attainment area for the Federal 8 hr averaged O3

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 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 O3 and PM2.5 standards. 

Sacramento County is in attainment for the Federal CO, NO2, and SO2 standards. It has attained 

the Federal PM10 standard and has requested resignation to attainment status. Sacramento 

County is a non-attainment area for the California O3, PM10, and PM2.5 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 October 15, 2011.

The primary focus of the current ambient air monitoring network is the collection of O3 and 

photochemical pollutant precursors such as NOX and VOC, and PM2.5 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 PM2.5 CSN trend site. The map 

below identifies the locations of current 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. To 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 pollution 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 site 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 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 ranging 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 population of 2.1 million. The 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

- 10 -

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 PM10 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 NOy analyzer, SO2 trace level analyzer, CO trace 

level analyzer, and low volume PM10 FRM sample in 2010. The low volume PM10 FRM sampler 

will serve as a PM10-2.5 (coarse) and non-source oriented Pb-PM10 monitor. The gaseous 

analyzers are operational beginning in July 2011.

Due to the revisions to the Lead Ambient Air Monitoring Requirement (Docket ID No. EPA–HQ–

OAR–2006–0735), effective January 26, 2011, the Pb-PM10 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, if the maximum Pb-PM10 threemonth arithmetic mean concentration is greater than or equal to 0.10 ug/m3. The District also 

may cease operation of the Pb-PM10 sampler when the Pb-TSP sampler becomes operational.

Due to the revised SO2 NAAQS, a plan for establishing the required SO2 monitoring sites shall be 

submitted to EPA by July 1, 2011, as a part of the Annual Network Plan. One SO2 monitor is 

required in this CBSA. This requirement is met using the trace level SO2 FRM monitor operating 

at Del Paso Manor NCore station.

The revised SO2 NAAQS introduced a requirement for the minimum number of SO2 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 SO2 emission is 694 tons per year). If the PWEI is 5,000 and 

10,000, then a minimum of one SO2 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 the 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 approved to proceed. The District is evaluating to relocate the CO monitor 

to one of the required NO2 near-roadway sites that must be operational no later than January 

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

of the CO NAAQS review.
- 11 -

Sacramento-Goldenland Ct

As mention under Sacramento-Del Paso Manor, a PM10 TEOM was relocated from Del Paso 

Manor in July 2010.

The District will submit a request for termination of the CO monitor and PM10 SSI at this site. 

Termination of these monitors will free up resources necessary for operation of the future NO2

near-roadway sites. The District will comply with monitoring requirements as promulgated in 

the final rule of the CO NAAQS.

North Highlands-Blackfoot Way 

EPA approved the request for SO2 analyzer termination on November 3, 2010. Thus, the 

District terminated the SO2 monitoring at this location

The District will submit a request for termination of the PM10 SSI sampler.

The District is evaluating shutting down the O3, CO, and NO2 at this site. This site is a redundant

air monitoring site and was originally sited to support a proposed power plant project at 

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

support the new NO2 near roadway monitoring sites, 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 PM10 SSI, PM10 TEOM, and PM2.5 FRM at 

this site. The PM10 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 usable for forecasting or analysis 

due to negative bias during the winter time when there is wood combustion. The PM2.5 FRM is 

redundant, as it collects the same PM2.5 data as the nearby T St site.

Sacramento-Sloughhouse Rd

The District requested the site owner 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 O3 monitor was changed from SPM to SLAMS.
- 12 -

5.0 Process to review changes to PM2.5 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 PM2.5 monitoring network that impact the location of a 

violating PM2.5 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 PM2.5 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 PM2.5 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 days, 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 58 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.

APPENDIX A

Comparison of Number of PM2.5 Monitors by Area and Population

The Sacramento MSA has a total of 16 PM2.5 monitors: 5 FRM, 9 BAM, and 2 SASS monitor. 8

of the 16 PM2.5 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 

PM2.5, a comparison of the number of PM2.5 monitors by geographic area and population in 

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

25,000 3.9 26 1 per 150,000 1 per 962

The numbers of PM2.5monitors per person show that the Sacramento MSA has a higher than 

average number of monitors per person. The numbers of PM2.5monitors 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 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) compared 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 Joaquin Valley has the typical PM2.5

sources of motor vehicles and residential wood combustion, but it also has agricultural sources 

of PM2.5. 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 

features and needs of that District.

APPENDIX B

Current Detailed Site Information

B.1 Sacramento- Branch Center #2

Sacramento-Branch Center #2 is a PM10 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.

B.2 Elk Grove- Bruceville

Sited in a rural area 4 miles south of Elk Grove, CA, Bruceville air monitoring site was initiated in 

1992. It replaced the former Sacramento-Meadowview Road O3 monitoring site. 

This site is the upwind O3 and ozone precursor monitoring site for our network. It is also a 

PAMS Type 1 site. It measures O3, NO2, total NMHC, speciated VOC (episodic only), PM2.5 BAM, 

WD, WS, TMP, RH, SRD, UV radiation, precipitation, and atmospheric pressure

Adjacent to the air monitoring site is the Franklin Field Radar Wind Profiler (RWP) for 

measurement of upper level winds and temperature. This RWP is operated year-round. 

Collection of upper air meteorology data is a requirement for the PAMS program.

B.3 Sacramento- Del Paso Manor

This site has been in existence since 1979. This air monitoring site is the largest air monitoring 

site in the Sacramento Valley air basin. This site may be one of the largest air monitoring sites

in Northern California, in terms of number of parameters measured.

It measures O3, CO, NO2, SO2, NMHC, speciated VOC (C2-C12), Carbonyl, PM-10 (SSI- main and 

collocated), PM-10 TEOM, PM-2.5 FRM (main and collocated), PM-2.5 BAM, Speciated PM-2.5 

(SASS), Black Carbon (Aethalometer), Scattering Coefficient (Nephelometer), WD-resultant, WSresultant, ambient temperature, relative humidity, and total solar radiation. 

This site is a PAMS Type 2 primary site and a PM-2.5 Speciation Trend Network (STN) site. This 

site is the current PM-2.5 design value site for this MSA.

In October 2009, EPA- Region IX approved this monitoring site as an NCore site. This is one of 

six NCore sites proposed for California. The District plans to operate an NCore site at Del Paso 

Manor, no later than January 1, 2011.

To accommodate the NCore monitoring instrumentation, the District expanded the size of the 

existing roof deck, added a 10 meter NOY converter tower, and upgraded the electrical capacity 

in Spring 2010.

B.7 North Highlands-Blackfoot

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

site for O3, CO, and NO2. This site is a SLAMS site for PM-10 SSI. SO2 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 McCllean Air Force Base, which was 3 miles southwest of the site. The purposed power plant 

project was canceled during the early 1980’s.

During an annual review of SLAMS network design in the mid-1990s, the District needed additional 

NAMS sites for SO2 and PM10 to meet minimum monitoring requirements. Thus, the designation of 

the SO2 and PM10 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, this site measures O3, 

wind direction, wind speed, and PM2.5.

Sloughhouse was established in 1997 as a seasonal (April-October) O3 special purpose 

monitoring site to measure elevated afternoon O3 concentrations, under northwesterly winds, 

in support of the District's summer Spare the Air (O3 episodic control measure) program. It was 

sited to cover “data gaps” in the O3 monitoring network, which is still used for forecasting 

summer AQI levels.

A tree existed within 10 meters southeast of the O3 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 complies with Appendix E (Probe and 

Monitoring Path Siting Criteria), the O3 monitor was re-classified from SPM to SLAMS.

Since November 2008, seasonal (November-February) monitoring for PM2.5 is conducted at this 

site. A special purpose PM2.5 E-BAM monitor collects data in support of the South Sacramento 

County Winter PM2.5 study. This study has been extended, due to the extremely low data 

capture rates during the 2008 and 2009 winter seasons.
