# AIR MONITORING NETWORK PLAN

Background

Formed in 1974, the Monterey Bay Unified Air Pollution Control District ( District ) is the public agency

responsible for air quality management in Monterey, Santa Cruz, and San Benito Counties

, which make

up the North Central Coast Air Basin (NCCAB)

. The District collects and reports data from a network of

six air monitoring stations throughout the NCCAB

. These monitoring sites include five State a nd Local

Air Monitoring Stations (SLAMS) and three Special P urpose Monitoring (SPM) station s

.

## 2

Seven of the stations are directly operated and maintained by the D istrict

. The Pinnacles site is operated

and m aintained by the National Parks Service

. The District also performs sho rt

- term monitoring and

special testing as needed

. The District also maintains a network consisting of both mobile and stationary

instruments

, which include beta attenuation monitors, BAM

- 1020s and E

- BAMs that are primarily

intended for the detection of PM2.5 from outdoor and residential burning, as well as wildfires

.



# NETWORK DESCRIPTION

Network Plan

The District adopt s and submit s an A nnual M onitoring N etwork P lan to the EPA Regional Administrator

. This plan provides for the establishment, maintenance, and evolution of an air quality monitoring system.

The Code of Federal R egulations currently requires that th is report be submitted to the U.S.

Environmental Protection Agency (U.S. EPA) by July 1 of each year. The geographical scope of this

report consists of Monterey, Santa Cruz, and San Benito counties , which make up the North Central Coast

Air Basin (NCCAB) in California

.

General Information

The a mbien t air quality standards are limits on air pollutant concentrations . They are set by the California

Air Resources Board ( C ARB ) and the EPA

, and they are designed to protect human health and the

environment. Based on these standards, the District monitors the air qualit y in the NCAAB. I f an area

does not meet the air quality standards, then regulations and control strategies are developed to reduce

pollutants. The District collects data on both pollutant and meteorological parameters. The primary

pollutants of concern, from a regulatory and public health perspective, are O3, PM2.5, and PM10. Most

sites monitor for multiple pollutants and some sites collect data for other pollutants, such as NO

- NO2

- NOx, and CO. Meteorological parameters are monitored at all sit es and include atmospheric temperature

monitors (ATM), wind speed average (WSA), and wind direction average ( WDA)

.

Data Use

The a ir monitoring data collected by the District is used in a number of ways. It is available to various

regulatory agencies

, health and environmental researchers, and to the general public ; includ ing

en vironmental groups, business es , and concerned citizens

. This data is reviewed for compliance with the

ambient air quality standards , as well as associated public health and envir onmental effects and impacts.

The data is submitted to CARB and the EPA

, and is published on the District’s website, the “AirNow”

website

, and in newspapers

.

EPA Monitoring Require ments

EPA regulations dictate the mi nimum number of monitoring sites to be established by S tate and l ocal air

agencies. The District network meets the minimum monitoring requirements for all criteria pollutants

(Tables 1

- 5 ). These requirements are based on local Metr opolitan Statistical Area (MSA) data

, as set

forth in the Code of Federal Regulations, ( 40 CFR 58 ) . MSA s are part of a classification of geographical

regions developed by the U.S. Census Bureau and include one or more counties , although not all counties

fall within an MSA. For the criteria pollutants, such as O 3, PM2.5, and PM10, the required minimum

number of monitoring sites is based on both the population and t he pollutant concentration in a MSA

.

## 3

The San Jose

- Sunnyvale

- Santa Clara MSA falls across the jurisdictions of both the Monterey Bay Unified

Air Pollut ion Control District and the Bay Area Air Quality Management District (BAAQMD). Because

of this, in accordance with 40 CFR Part 58, Appendix D, Section (2)(e), and interagency agreement (See

Appendix B) has been entered into in order for both Districts to share responsibility in meeting some of

these requirements. S tate and local agencies may deploy additional monitors to meet more stringent S tate

standards, to track specific local air quality issues, or to address local public concerns

. For example,

CA RB which is the primary quality assurance organization for MBUAPCD, maintains a network of

collocated PM2.5 sites. The Salinas Air Monitoring Station is part of that network and maintains

relatively low design values (See detailed site information)

## Ambient Air Quality Standards

The EPA sets National Ambient Air Quality Standards (NAAQS

- Table 6 ) for criteria pollutants as

directed by the Federal Clean Air Act. The State of California has adopted a set of S tate standards (Table

7 ) which are required to be at least as stringent as the NAAQS. The S tate standards and the federal

primary standards are both designed to protect the health of the public

. The S tate standards and the

federal secondary standards safeguard public welfare , including protection against decreased visibility

, damage to property

, and damage to the environment

. The federal primary and secondary standards for the

pollutants currently meas ured in the NCCAB are identical

.

(Note: The EPA adopts both rounding and truncating conventions depending on the standard

. Where rounding conventions are

used, a s long as the measured pollutant level does not round up to a value higher than the standard, as read with the same number

of significant digits as listed by the standard, the standard is not considered to be exceeded.

## Quality Assurance

The District follow s a quality assurance program to ensure compliance with the regulations set within 40

CFR 58

. Consistent with these federal regulations, t he C alifornia Air R esources B oard, Quality

Assurance Section ( C ARB QAS) conducts an nual performance evaluations of nitrogen dioxide, ozone

and carbon monoxide analyzers

, meteorological instruments, and flow rates for PM2.5 and PM10

m onitor s

. C ARB QAS also conducts site evaluations as part of the annual audit at each air monitoring

station . Physical measurements and observations, including probe/sensor height above ground level,

distance from trees, type of ground cover, residence tim e, obstructions to air flow, distance to local

sources, topography, vehicle counts, predominant wind direction, and probe material are used to

determine compliance with the requirements of 40 CFR 58, Appendix E

.

The CARB QAS als o ensures the quality of the data collected by the air monitoring sites operating in the

NCCAB . This is done on a monthly basis through analysis of precision data submitted to the U.S. EPA

Air Qu a lity System ( EPA A QS )

. The EPA review s the frequency of flow rate verifications for manual

samplers and the frequency of one

- point quality control checks for gaseous instruments. On an annual

basis, the EPA perform s an analysis of the precision data that concentrates on three parameters: pre cision

data submission, validity, and usability. The data analyses are conducted in accordance with 40 CFR 58,

Appendix A

.

The EPA QAS

, through a contractor, conducts annual flow rate audit s on PM2.5 and PM10 monitors

. The District performs both weekly and monthly checks of instrument functionality

. Calibrations are done

on either a quarterly or a semi

- annual basis depending on the individual requirements for each instrument

. The District has collocated PM2.5 monitors in Salinas a s a further quality check as required by 40 CFR

58, Appendix A

.

Finally, C ARB QAS conducts technical systems audits to determine if the District ’s air monitoring

program satisfies the requirements of 40 CFR 58

, and U.S. EPA’s Quality Assurance Handbook for Air

Pollution Measurement Systems, Volume II, April 1994. Compliance with these regulations is necessary

for the data to be considered data

- for

- record

, as required by the California Code of Regulations (Title 17,

Article 3, S ection 70301) . Data meeting these requirements is eligible to be used in actions taken

pursuant to the Federal and State Clean Air Act s

.

## 6

Proposed Modifications to Network in the Next 18 Months

There are several p roposed changes to the air monitoring network approved by the District’s Board and

the APCO to reduce air monitoring costs and improve efficiencies by shutting down monitoring

parameters a nd stations

.

 Parameter changes for SLAM stations:

o None planned at this time.

 Parameter changes for SPM stations :

o The District will continue to carry out a PM2.5 survey of wood smoke concentrations

during the winter season s in the Santa Cruz mountain area in the San Lorenzo Valley

.

o The District intends to conduct a roadside monitori ng study in Salinas , looking at trace

level NOx, trace level CO, black carbon, PM2.5, and MET in 2013.

Modifications Made to Network in 20 1 2 and Early 201 3

The District collected data from seven monitoring sites in 20 1 1

. The following sites and/or monitoring

parameters were changed:

 A special purpose air monitoring station was started up in August , 201 2 for a term of two years to

collect ozone data in Scotts Valley.

 A special purpose air monitoring station was started up in March , 201 3 for a term of three years

to collect PM2.5 data in Felton

.

 The King City Air Monitoring Station Building was replaced during June 18 th 

## to June 22 nd 

## 2012.



# REVIEW OF CHANGES TO PM2.5 MONITORING NETWORK

The NCCAB is currently in compliance with the PM2.5 ambient air quality standards. In the event that

standards are exceeded

, appropriate changes will be made to the PM2.5 monitoring network. This would

then be documented in the A nnual N etwork P lan which would then undergo a 30

- day public review

before submittal to the EPA

.



# DATA SUBMISSION REQUIREMENTS

Precision reports are submitted to the EPA’s A erometric I nformation Retrieval S ystem

. Annual data

certification is submitted by May 1 , each year.

# Detailed Site I nformation f or State and Local Air Monitoring Stations (SLAMS)

Salinas 3

This s tation was established in December 1999 to monitor air quality conditions in the Salinas MSA, the

District’s most populated area. This station features one of the District’s most extensi ve set of

measurements. The data collected include CO, NO 2

, O 3 , PM 2.5

, 

## BAM

- PM 2.5 , WS A , WD A and A T M

. PM2.5 data is collected hourly using the FEM BAM

- 1020 as the primary instrument

. It is also collected

by an R&P FRM

- 2000

, a filter based instrument operatin g on the 1 in 6 day schedule , which is collocated

to the BAM

- 1020

. The collocation is required by CARB, our Primary Quality Assurance Organization

( PQAO ) , and is a part of their overall collocation network. The PM2.5 filters are analyzed by BAAQ MD

according to EPA specifications (See following two pages). Data from this populated area generally

indicate good air quality and meet all S tate and federal standards for CO, NO 2

, O 3

, 

## and PM 2.5 . Data

from this site have been useful in assessing air pollution impacts on populations during unusual events,

such as wildfires at Fort Ord. The 2012 PM2.5 annual design value is 6.2μg/m 3 

## for the primary

instrument (BAM

- 1020) and 6.1μg/m 3 

## for the collocated instrument (R&P FRM

- 2000). The 2012 PM2.5

24 Hour design value is 14μg/m 3 

## for the primary instrument (BAM

- 1020) and 14μg/m 3

Carmel Valley

This station was established in 198 2 due to the smoke sensitive nature of the rural/residential Carmel

Valley

. The limited natural ventilation of the valley can also lead to trapping of ozone. Measurements

made at this site include O 3

, PM2.5, WS A , WD A

, and A T M

. Data from this location has been useful for

issuing public Health Advisories during wildfire events

. A siting waiver for this station ha d been sought

and approved by the EPA (See Appendix C) due to the presence of a nearby tree

. The current PM2.5

monit or has not yet been in place long enough to calculate a design value.

# Detailed Site information for Special Purpose Monitoring (SPM) Sites

Pinnacles National Park

This station was established in 1987 by the National Parks Service (NPS) to monitor conditions at

Pinnacles National Park , which is a federal Class I protected a rea, and part of the N ational P ark

M onitoring N etwork operated by the National Parks Service. Data acquired at this site include O3, WS,

WD , and ATM . In addition, as part of the federal Interagency Monitoring of Protected Visual

Environments (IMPROVE) program, a wide variety of particulate aerosols i s monitored for the purpose

of assessing visibility trends. However, the only parameters reported by the District at this site are O3 and

8HrO3. Although this site is located in a remote and unpopulated area, ozone readings there are the

highest in the District and the ozone data are used to establish the NCCAB’s designations in relation to

th e S tate and federal standards. C ARB’s triennial transport assessments have demonstrated that the cause

of the high readings at this mountai n site ha s often been overwhelming transport, particularly from the

upwind San Francisco Bay Area. Nitrate data from the IMPROVE monitors have also been used in

District plans to indicate an improving trend. This is most likely due to regional reductions in motor

vehicle NOx emissions, as well as controls on stationary sources.

Scotts Valley

This station was set up in August of 2012 and will run until July of 2014 for the purpose of

monitoring ozone. Historically, Scotts Valley generally had the District’s third highest ozone patterns

. Data from this area had been used for ARB’s triennial transport assessments

, which found that duri ng

exceedance events the area could be strongly impacted by transport from the San Francisco Bay Area Air

Basin

. The pres ent station was put in place to assess current ozone trends to see if further monitoring is

warranted. Data collected hourly at this site include O3, WSA, WDA and ATM.
