Section 1. 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, to 

submit an Annual Monitoring Network Plan to the U.S. Environmental Protection 

Agency (EPA), no later than July 1st, each year. 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, 2012-December 31, 2012.

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) 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 (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. This

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 nonSPM 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 network plan focuses on the monitors that are operated within Sacramento 

County, which is a part of Sacramento-Arden Arcade-Roseville Metropolitan 

Statistical Area (MSA). For details on monitors in neighboring counties within the 

MSA, please refer to the latest California Air Annual Monitoring Network Report 

for Small District in California <http://www.arb.ca.gov/aqd/amnr/amnr2012.pdf>.

Section 2. Network Operations

Sacramento County is located in the middle of California’s Central Valley and at 

the southern end of the Sacramento Valley. Sacramento County is the most 

populous part of the Sacramento-Arden Arcade-Roseville, California, MSA 

(Sacramento MSA). The Sacramento MSA also includes the western sections of 

Placer and El Dorado County, Yolo County, and parts of Solano and Sutter 

Counties. According to the latest U.S. Census estimates, Sacramento MSA is 

the 25th largest MSA in the U.S. by population. It has 2.2 million people, of which 

1.4 million of those reside in Sacramento County. Figure 2-1 shows a map of 

Sacramento MSA.

The Sacramento MSA is a non-attainment area for the Federal 8hr O3 standard 

and is referred to as Sacramento Federal Nonattainment Area (SFNA). The area 

is shown in Figure 2-2. While Sacramento is designated as a federal nonattainment area for PM10 and 24-hr PM2.5, it has met both standards and is 

currently working with EPA to re-designate the attainment status. Sacramento 

County is in attainment for the Federal CO, NO2, and SO2 standards. The 

California Air Resources Board recommended that EPA designate Sacramento 

County as unclassified for the 2008 Federal Pb standard.

SMAQMD operates ten air monitoring sites within Sacramento County. While 

most sites operate a suite of instruments to monitor multiple pollutants and 

meteorological condition, only a few sites monitor a specific pollutant. Each site 

has monitors that belong to one or more national monitoring networks, such as 

SLAMS, PAMS, NCore and CSN, or is an SPM. In addition to SLAMS and 

PAMS, SMAQMD operates one of the 80 NCore sites and one of the 54 PM2.5

CSN trend sites. Figure 2-3 shows the location of these monitoring sites, which 

includes one site that is operated by ARB: Sacramento-T Street. Table 2-1 lists 

the type of monitoring network each site belongs to and the pollutants monitored 

at each site.

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. The network is designed to 

meet three basic monitoring objectives: (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 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. An overview of monitoring 

objective is in Table 2-2.
2013 Annual Monitoring Network Plan July 1, 2013

Page | 3

The physical siting 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 2-3 summarizes 

the site type and spatial scale. For in-depth details on individual monitors, 

including monitoring objective and statement of purpose, see Appendix B, 

Detailed Site Information. Site type and spatial scale description can be found in 

Appendix D to 40 CFR 58.

Section 3. Minimum Monitoring Requirements

Depending on the specific pollutant, the minimum number of monitors required

for each pollutant is based on the one or more applicable factors as described in 

Appendix D to 40 CFR 58: MSA population, pollutant design value, pollutant 

maximum concentration, attainment status, annual average daily traffic (AADT), 

state implantation plan (SIP), maintenance plan, population weighted emission 

index (PWEI), and EPA’s national emission inventory (NEI) data.

Sacramento MSA meets or exceeds minimum monitoring requirement for all 

criteria pollutants – O3, PM2.5 (manual and continuous methods), PM10, NO2, 

SO2, CO, and Pb. Details of the minimum monitoring requirements of all criteria 

pollutants are provided in tables 3-1 and 3-2. Monitors in these tables represent

Sacramento MSA (or CBSA, ID#40900). As mentioned in Section 2, Sacramento 

MSA has 2.2 million residents (U.S. Census, 2010) and is composed of El 

Dorado, Placer, Sacramento, and Yolo Counties.

In addition to the criteria pollutants, Sacramento MSA also meets minimum

monitoring requirement for PAMS, which is required due to the severity of ozone 

non-attainment classification in Sacramento MSA. Currently, there is one of 

each PAMS type I, II, and III sites. There is also a secondary type II site. Table 

3-3 lists the instruments operating at each PAMS.

Furthermore, all instruments operated by SMAQMD meets operating schedule 

requirement as specified in 40 CFR Part 58.12. As required, all continuous 

monitors reports hourly data. Sampling schedule for non-continuous monitors is 

summarized in Table 3-4. Design value is included in the table if it is needed to 

maintain a specific schedule, for non-continuous monitors. All monitors are 

operated year-round except VOC and carbonyl samplers at PAMS and special 

purpose PM2.5 monitors at Sloughhouse and Rancho Seco. For details on 

sampling season and operating schedule, please refer to Appendix B.

Section 4. Recent and Proposed Modification to the 

Network

This section discusses recent and proposed modification to the monitoring 

network. As required by 40 CFR Part 58.10, modifications within the next 18 

months are included. While the District is not requesting approval for 

modification through this network plan, the modifications discussed in this plan 

include the following:

Sacramento-Bercut Dr. (Proposed Site)

Bercut Dr. is tentatively selected as the near-road monitoring site contingent on 

approval from the EPA. Final revision to ambient NO2 monitoring requirement 

(EPA Docket ID EPA-HQ-OAR-2012-0486) requires this site to be operational by 

January 1, 2014. Appendix C to this network plan discusses site selection 

criteria and the rationale to locate the near-road monitoring site at this location.

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

pollutants – NO2 and CO – as well as optional pollutants and meteorological 

parameters – black carbon, wind direction, wind speed, temperature, and relative 

humidity. In anticipation of the upcoming PM2.5 near-road monitoring

requirement, January 1, 2017 deadline for Sacramento CBSA per final rule of 

PM2.5 NAAQS review (78 FR 3086), the District will also install a PM2.5 monitor. 

Appendix B lists the details such as site type and objective for planned 

instruments at this site.

Elk Grove-Bruceville Rd.

The District is considering to discontinue the speciated VOC measurement. 

Appendix D to 40 CFR Part 58 requires only two speciated VOC measurement 

sites per PAMS network area, and Sacramento-Del Paso Manor (type II PAMS) 

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

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

concentration.

Sacramento-Del Paso Manor 

The District installed a PM2.5 FEM continuous monitor in September 2012 to 

replace the non-FEM monitor because the PM2.5 2011design value was within 

95% of NAAQS. As allowed by 40 CFR 58.20, the FEM monitor was installed as 

a special purpose monitor (SPM). Comparability test concludes that the FEM is 

not comparable to a collocated FRM monitor due to seasonal variability. 

Specifically, the multiplicative bias was outside of acceptable limit during nonwinter months (40 CFR Part 58.35 defines winter as ―coolest three or four 

months of the year at the site‖). The comparability test was performed in 

accordance to 40 CFR Part 58.35. In April 2013, the District relocated the PM2.5

FEM monitor to Folsom-Natoma St, where the monitor will continue to operate as 

an SPM.

Throughout 2012 and 2013, the existing PM2.5 FRM monitor remained the 

primary PM2.5 sampler for comparison to the annual ambient air quality standard. 
2013 Annual Monitoring Network Plan July 1, 2013

Page | 15

In December 2012, the FRM monitor’s sampling frequency increased from 1 in 3 

days to daily sampling to provide daily PM2.5 data that is comparable to the 

NAAQS.

The District is evaluating to shut down the Nephelometer. The monitor was 

originally installed in 1999 for the California Regional Particulate Air Quality 

Study. After the study ended in 2001, the monitor was not removed and became 

a special purpose monitor. 

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 termination process was postponed, 

as the street/sidewalk project was delayed until April 2013. This site will be 

terminated in early 2013 when the project proceeds. A copy of the approval 

letter is attached in Appendix D.

Folsom-Natoma St

In April 2013, the PM2.5 non-FEM continuous monitor was relocated to the 

Sloughhouse site and was replaced by a continuous FEM monitor. The FEM 

monitor will operate as an SPM while the District performs a data quality 

assessment. This special purpose monitor is not eligible for comparison to 

NAAQS because 40 CFR Part 58.20 allows SPM operating less than 24 months 

to be excluded from NAAQS comparison.

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 planning to request 

approval for termination of the PM10 SSI sampler. Also, the district is evaluating 

to adapt a seasonal sampling schedule for O3 and CO. Staff resource used to 

support this air monitoring site would be reassigned to support the new NO2 near 

roadway monitoring sites. 
2013 Annual Monitoring Network Plan July 1, 2013

Sacramento Health Dept.-Stockton Blvd.

The District will submit a request for termination of the PM10 TEOM and PM10 SSI 

monitors. The TEOM monitor is not required, and its data is not used for 

forecasting or analysis due to its negative bias during the winter time when there 

is an abundance of wood combustion. The SSI monitor also is not required 

because there is a sufficient number of SSI monitors in Sacramento MSA to meet 

the minimum monitoring requirement.

Also, the District is considering to terminate the PM2.5 FRM monitor. This monitor

is redundant as it collects the same PM2.5 data as the nearby Sacramento-T 

Street. 

Sloughhouse

A non-FEM PM2.5 BAM monitor was relocated from Folsom-Natoma St. in April

2013. It replaces the existing PM2.5 E-BAM monitor.

Section 5. PM Collocation Requirement

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

58 requires collocation for PM10, PM2.5 FRM and FEM, and PM10-2.5 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.‖

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, PM2.5 FRM and PM10 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 2012 

prepared by CARB (http://www.arb.ca.gov/aqd/amnr/smnetrpt12.pdf).

Section 6. Process to Review Changes to PM2.5 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 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.‖ 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 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.

Section 7. Data Submission Requirements

CARB submits precision, accuracy, and raw data for all District operated 

monitors in 2012. CARB is also the lead agency on annual data certification. 

The following submission dates are provided by CARB.

 2012 Precision/Accuracy reports submitted to AQS: May 2013

 2012 Annual data certification submitted: May 2013 (by CARB)

Section 8. Review of Existing SMAQMD 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 PM2.5 monitors per person show that the Sacramento MSA has 

a higher than average number of monitors per person. The numbers of PM2.5 

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 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 Detailed Site information

Detailed site information covered in this appendix reflects air monitoring 

operation from January 1, 2012-December 31, 2012.

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.3 Elk Grove-Bruceville

Bruceillve air monitoring site is sited in a rural area 4 miles south of Elk Grove, 

CA, and 20 miles south of Downtown Sacramento. It was initiated in 1992 to 

replace the former Sacramento-Meadowview Road O3 monitoring site. 

This site is the upwind O3 and ozone precursor monitoring site for our network, 

also known as a PAMS Type I 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.4 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 is one of the 

largest air monitoring sites in Northern California, in terms of number of 

parameters measured.

It measures O3, CO (trace level), NO2, NOy, SO2 (trace level), NMHC, speciated 

VOC (C2-C12), Carbonyl, PM10 (SSI- main and collocated), PM10 TEOM, PM10 

coarse, Pb-PM10, PM2.5 FRM (main and collocated), PM2.5 BAM, Speciated PM2.5

(SASS), Black Carbon (Aethalometer), Scattering Coefficient (Nephelometer), 

WD-resultant, WS-resultant, ambient temperature, relative humidity, and total 

solar radiation. 

This site is a PAMS Type II primary site and a PM2.5 Chemical Speciation 

Network (CSN) site. This site is the current PM2.5 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 operating in California. 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.8 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 PM10 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 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 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, which is now categorized as 

SLAMS.

B.10 Sloughhouse

Located in a rural area 16.5 miles southeast 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 used for forecasting summer AQI levels.

A tree 10 m southeast of the O3 inlet was removed 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

Appendix C Near-Road NO2 Monitoring

Introduction

In 2010, U.S. EPA promulgated new nitrogen dioxide (NO2) monitoring 

requirements. Local agencies are required to install and operate new near-road 

monitoring stations where hourly maximum NO2 emissions are expected. 

Deployment deadline revised on March 7, 2013, (EPA Docket ID EPA-HQ-OAR2012-0486) requires the first tier of near-road monitoring site, which includes the 

Sacramento—Arden-Arcade—Roseville CBSA, to be operational by January 1, 

2014. The Sacramento CBSA is required to have one near-road NO2 monitoring 

site according to the population and traffic criteria given in Appendix D to 40 CFR 

58. The Sacramento CBSA has a population of 2.2 million (2010 U.S. Census 

count) and annual average daily traffic (AADT) count of 246,000 on the most 

travelled road (2011 Caltrans count). The District will install the near-road 

monitoring site and have it operational by January 1, 2014.

To determine the location with the maximum NO2 emissions, the top ten sites 

with the highest number of cars and trucks traffic were identified, see Figure C-1. 

Each of these locations was reviewed according to the guidelines provided by 

U.S. EPA in the Near-Road NO2 Technical Assistance Document (TAD). For 

example, annual average daily traffic (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. 

Location

Through a series of siting and guideline review, which are discussed in the 

following sections, the Districts determines that a site on Bercut Dr. in

Sacramento (38.593328°N, -121.503728°W) is the best location to meet nearroad NO2 monitoring goals. Located less than one mile northeast of Downtown 

Sacramento, Bercut Dr. is nearly parallel to Interstate 5 (I-5) but is not a frontal 

road, as traffic from I-5 has no direct access to Bercut Dr. The closest major 

intersection to the potential site is Richards Blvd to the north, which has on and 

off ramps to I-5. This site does not have any distinguish feature that makes the 

site unique so that the pollution measured is representative to other near-road 

locations in the CBSA.

If this site is approved as a near-road monitoring site, the District would partner 

with California Department of Transportation (Caltrans) and utilize its building on 

Bercut Dr. to shelter monitoring equipment. Note that this site is 250 feet north 

of the old site that was presented in the 2012 Annual Network Plan. Figure C-2, 

C-3, C-4, and C-5 show location and ground view of the potential site.

Traffic Data

The site on Bercut Dr. would monitor NO2 emissions from I-5. The 150 block of 

Bercut Dr. is located north of I Street on I-5 and south of Richards Blvd. I-5 is a 

major highway that runs parallel to the West Coast. In addition to linking with two 

regional highways, it also links with Interstate 80, a transcontinental highway. A 

map was shown in Figure C-1.

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

of fleet equivalent (FE) AADT. The 2011 latest statistics maintained by the 

Traffic Data Branch of Caltrans, AADT on this targeted roadway is 186,000, of 

which 18,000 is heavy duty truck traffic. FE AADT is a quantitative way to 

compare NO2 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 EMission 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 ratio is calculated and 

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

NO2 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 the highest in 

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

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 north 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 projects in its Metropolitan 
2013 Annual Monitoring Network Plan July 1, 2013

Page | 68

Transportation Plan 2035. The plan includes 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, fleet 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-2 details 

the NOx model emission in Sacramento County for calculation of emission ratio.

Physical Considerations for the Selected Site

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

Near-Road NO2 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 NO2

concentration captured. The characteristics 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 

NO2 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 profile 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 Criteria as specified in 40 CFR Part 58.

• Roadside structure – This portion of Interstate 5 does not have 

obstructions (i.e., sound wall) that funnels NO2 downwind and prevents 

the capture of the highest NO2 concentration. The District is working 

with Caltrans to remove short vegetation along the roadway to 

minimize any adsorption or reaction effect on NO2.

• 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. Figure C-6 shows the wind rose 

compiled by Western Regional Climate Center using 30 years of 

measurement taken at the airport since 1983.

Bercut Dr. Site has no undesirable attributes that would potentially decrease the 

maximum NO2 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 Caltrans to draft a lease agreement for the site.

The sampling inlet probe will 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 recommendation provided in the NearRoad NO2 TAD as well as the Near-Road NO2 Siting Criteria in Appendix E to 

40 CFR, Part 58. A complete matrix among the top ten FE AADT sites is 

provided in Table C-3 and C-4.

Population Exposure

As suggested by the TAD, Bercut Dr. Site was selected despite having limited 

population exposure to NO2. The TAD states that population exposure should 

only be used if two identical sites existed. Current land use around Bercut Dr. is 

zoned primarily for commercial use. There is limited residence in the vicinity. 

However, within the next 3-5 years, City of Sacramento will develop 240 acres of 

land nearby to include medium density housing. Population exposure is 

considered, but this factor is relatively minor compared to the fleet equivalent 

AADT (FE AADT). 

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 NO2 emissions Therefore, this site is likely to measure the 

highest NO2 concentration in Sacramento—Arden-Arcade-Roseville CBSA.
