### Introduction

This document is the Connecticut 201 5 Air Monitoring Network Plan (Network Plan) , prepared by the

Connecticut Department of Energy and Environmental Protection (DEEP) in accordance with 40 CFR

58.10. This plan meets the requirement to develop and submit to the Environmental Protection Agency

(EPA) an annual air quality m onitoring net work plan to describe the air monitoring network and propose

an y changes of air quality monitoring sites and monitored air pollutants planned in the 18 months

following submittal

.

DEEP held a public comment period from May 15 , 201 5 to June 14 , 201 5 , for the d raft Network Plan. The

Network Plan is posted on DEEP’s website at DEEP: Air Monitoring Network

.



### Background

The Clean Air Act of 1970 (CAA) established the Environmental Protection Agency as the principal

administrative body to enact regulations to meet the requirements of the CAA and subsequent

amendments thereto . One such requirement directed EPA to set prima ry and secondary air quality

standards, known as the National Ambient Air Quality Standards ( NAAQS) for the six “criteria pollutants”

that Congress determined presented serious negative impacts to human health and welfare. For areas

within Connecticut that do not meet a NAAQS, DEEP develops State Implementation Plans (SIPs) to detail

the steps to be taken to bring air quality into attainment. Ambient air quality monitoring is essential to

track progress towards meeting clean air goals and demonstrate attai nment.

While DEEP monitors ambient air quality in Connecticut primarily for comparison with the NAAQS, there

are other important objectives to ambient air quality monitoring. This monitoring provides local air

quality data to the public, supports air q uality forecasting and the Air Quality Index (AQI), supports long

term health assessments and other scientific research, assists with air permitting and identifying long

term air quality trends to gauge effectiveness of air pollution control strategies and serve s as an accuracy

check on computer based air quality models. DEEP’s ability to manage the air quality monitoring network

depends significantly on federal support from EPA.

F uture federal funding levels for air monitoring programs remain uncertain. In addition, as with state

governmental operations everywhere, state resources allocated to ambient air quality monitoring are

unable to keep pace with rising costs

. DEEP must continue to provide an acceptable level of service within

these constraints by continually improv ing and focus ing its efforts to ensure the completion of the most

critical ambient air quality monitoring. As operating costs and federal monitoring requirements increase,

DEEP must do more with fewer resources by either improving oper ational efficiencies or reducing other

aspects of the air monitoring network

. E fficiencies being employed include improvements to data

acquisition (through software upgrades and the automating of data streams previously manual) , to public

data access (tho rough Kiosks and improvements to the website), and to reduction of the number of

monitoring sites by increasing multi

- pollutant monitoring (resulting in consolidation of resources)

.



### Network Overview

DEEP currently operates 15 stations in its air monitor ing network (Figure 1) . Given continuously evolving

standards , this Plan assumes the current level of staffing and federal funding will be maintained through

federal FY1 5

. Should E P A monitoring requirements significantly increase or should DEEP be impact ed by

staff attrition or a reduction in federal funding , the level of effort proposed in this Plan will have to be

revisited.

In October 2006, EPA established a network of core multi

- pollutant sites . These sites are known as the

National Core (NCore) network , the primary purpose of which is to consolidate monitoring of multiple

pollutants at fewer sites for efficiency and cost savings. In addition, the NCore sites provide a

comprehensive suite of high

- resolution poll utant data for NAAQS compliance assessment, research

studies and long

- term trends analysis. There are t wo NCore sites located in Connecticut: Criscuolo Park

in New Haven, and Mohawk Mountain in Cornwall. Although these sites predated NCore, DEEP upgraded

both sites consistent with NCore requirements.Connecticut 2015 Annual Air Monitoring Network Plan 5

Proposed Network Changes

Details of the proposed monitoring network configuration are described in the following site informa tion

pages. In addition to infrastructure maintenance and improvements, DEEP proposes to make the

following changes to the monitoring network during the period 2015

- 2016 :

**•** Discontinuing Pb

- PM10 (lead) sampling at the New Haven Criscuolo Park NCore site on

Sept ember 3 0 , 2015 (end of EPA fiscal year)

.

**•** Commencing reporting of continuous PM 2.5 data from all remaining non

- FEM continuous PM 2.5 monitoring sites as federal equivalent method (FEM) data eligible for comparison to the PM 2.5

NAAQS on January 1, 2016

.

**•** Discontinu ing FRM PM 2.5 monitoring at the Westport Sherwood Island State Park site on December

31, 2015

.

**•** Reducing sampling frequencies to one

- in

- six days for PM 2.5 FRM monitors at Bridgeport Roosevelt

School, Danbury WCSU, East Hartford McAuliffe Par k and Waterbury Bank Street on January 1,

2016

.

**•** Reducing sampling frequency from every day to one

- in

- three days for the PM 2.5 FRM monitor at

New Haven Criscuolo Park on January 1, 2016

.

**•** Discontinuing PAMS VOC and NO/NO 2 /NO X monitoring at the Westport Sherwood Island State

Park as of January 1, 2015.

DEEP maintain s its air monitoring network to fulfill critical data needs. Recent EPA NAAQS rule revisions

have mandate d additional monitoring , reporting and analysis associated with the SLAMS networks, and

,

con sistent with the LEAN culture embraced by DEEP , this Network Plan calls for continued effort s to

streamline data handling

, while also looking for opportunities to identify and address low value added

monitoring sites. If li mited opportunities exist to disinvest from low value added monitoring sites,

efficiencies nonetheless will occur by eliminating lower value data collection. Such efficiencies will beConnecticut 2015 Annual Air Monitoring Network Plan 6

necessary to enable limited staff resources to focus o n competing priorities, which may not be limited to

air quality monitoring

. If efficiencies alone are insuffi cient, either additional resour ces will be required or

the scope of the monitoring program will need to be revisited.

Decommissioning Discontinued Sites : DEEP is planning to take steps to ensure that all former

monitoring sites are properly decommissioned with regard to shelter, landscaping, security, monitoring,

electronics and utility equipment during 2015

- 2016.Connecticut 2015 Annual Air Monitoring Network Plan 7

### National Ambient Air Quality Standards (NAAQS)

The EPA ’s Office of Air Quality Planning and Standards (OAQPS) has set NAAQS for six principal

pollutants, known as the criteria pollutants. Table 2 summarizes the current NAAQS compliance

requirements for the criteria pollutants

.

(1) Final rule signed October 15, 2008. The 1978 lead standard (1.5 μg/m3 as a quarterly average) remains in effect until one

year after an area is designated for the 2008 standard, except that in areas designated nonattainment for the 1978, the 1978

standard remains in effect until implementation plans to attain or maintain the 2008 standard are approved.

(2) The official level of the annual NO 2 standard is 0.053 ppm, equal to 53 ppb, which is shown here for the purpose of clearer

comparison to the 1

(3) Final rule signed March 12, 2008. The 1997 ozone standard (0.08 ppm, annual fourth

- highest daily maximum 8

- hour

concentration, averaged over 3 years) and rel ated implementation rules remain in place. In 1997, EPA revoked the 1

- hour

ozone standard (0.12 ppm, not to be exceeded more than once per year) in all areas, although some areas have continued

obligations under that standard (“anti

- backsliding”). The 1

- hour ozone standard is attained when the expected number of

days per calendar year with maximum hourly average concentrations above 0.12 ppm is less than or equal to 1.

(4) Final rule signed June 2, 2010. The 1971 annual and 24

- hour SO 2 standards were rev oked in that same rulemaking.

However, these standards remain in effect until one year after an area is designated for the 2010 standard, except in areas

designated nonattainment for the 1971 standards, where the 1971 standards remain in effect until impl ementation plans to

attain or maintain the 2010 standard are approved.Connecticut 2015 Annual Air Monitoring Network Plan 9

### Overview of Network Operation

DEEP operates a network of 1 5 sites throughout Connecticut used for monitoring air pollutant s and

meteorological parameters. This section contains information about monitoring methods and sampling

frequencies, as well as monitoring network maps for each pollutant parameter. N etwork changes planned

before the end of 201 6 are discussed as are any anticipated network changes beyon d that period.



### PM 2.5 

### Network

Network Design The DEEP PM 2.5 network

consists of Thermo Partisol ®

- Plus 2025/2025i

sequential FRM air samplers with BGI VSCC

(RFPS

- 0498

- 118 ) and Met One BAM 1020

continuous FEM air samplers ( EQPM

- 0798

- 122) at nine air monit oring stations

. The

distribution of PM 2.5 sampling methods in the

network and their applicability to NAAQS

attainment are s hown in Table 3. For the

NAAQS compliance monitors, valid data from

collocated and supplemental monitors,

respectively, are used to fill in any missing or

invalidated scheduled or nonscheduled days

for the primary data set used for computing

the design values. Four of the eight continuous

BAM samplers in the network are designated

FEM monitors (continuous FEM) , having

previous ly met performance criteria based on

comparison with co

- located FRM monitors,

while the remaining four are designated as

non

- FEM (continuous BAM)

, by DEEP request and EPA concurrence, for non

- NAAQS compliance purp oses

, such as AQI forecasting.

DEEP performed a network

- wide FRM/FEM analysis, described below, using the most current data to

determine the efficacy of designating addition al continuous BAM PM 2.5 samplers as FEMs. Based on this

review, DEEP is proposing to report all Met One BAM 1020 PM 2.5 data as FEMs commencing January 1,

2016. Given the increased availability of NAAQS compliance PM 2.5 data from the continuous FEMs , DEEP

also proposes to reduce sampling frequency to 1

- in

- 6 days at SLAMS sit es, with the exception of the two

NCore sites and the Hartford near

- road site

. Because DEEP maintains sufficient PM 2.5 sampling capacity in

the Bridgeport

- Stamford

- Norwalk metropo litan statistical area (MSA) and PM 2.5 design values in this area

continue to decrease, PM 2.5 sampling will be discontinued at Westport Sherwood Island State Park.

Continuous PM 2.5 BAM Performance Evaluation DEEP compared the continuous PM 2.5 (Met One BA M)

data with PM 2.5 FRM data for the 3

- year period 2012

- 2014. Hourly BAM data was aggregated to valid 24

- hour averages when at least 75 percent of the hours in each day were valid. In cases where BAMs haveConnecticut 2015 Annual Air Monitoring Network Plan 13

been designated FEMs in 2014, the FEM and non

- FEM d ata sets were combined for the 3

- year analysis

. Linear regressions performed on the correlation plots are given in Appendix A. The s lopes and intercepts

of the regression lines are summarized in Table 4. Figure 2 shows the results of these correlations

gra phically, where slope/intercept points enclosed by the polygon comply with EPA FEM performance

criteria.

The data indicate that three sites, Bridgeport Roosevelt School , East Hartford McAuliffe Park and

Waterbury Bank Street, currently meet FEM criteria. The remaining sites nearly comply, with the

exception o f Cornwall, where PM 2.5 concentrations are unif ormly low. Given these facts, Connecticut’s

relatively low PM 2.5 design values and DEEP ’ s ongoing commitment to implementing best practices in

field operations

, DEEP plans to consider all Met One BAM 1020 PM 2.5 monitors FEMs and commence

reporting this data as available for NAAQS compliance beginning January 1, 2016.

Proposed Changes in PM 2.5 FRM Sampling Frequencies: DEEP proposes reductions in manual (FRM)

sampling frequencies for most of the SLAMS PM 2.5 m onitors in the network, as allowed by CFR 40

58.12(d), where manual FRM and continuous FEM samplers are co

- located. All sites have design values

well below the threshold (85 percent of NAAQS level) that requires a minimum of 1

- in

- 3 day sampling

frequency. Specifically, DEEP proposes to reduce the New Haven Criscuolo Park NCore sampler from 1

- in

1 day to 1

- in

- 3 days, the East Hartford McAuliffe Park sampler from 1

- in

- 1 day to 1

- in

- 6 days, and the

following 1

- in

- 3 day samplers to 1

- in

- 6 days: Bridgeport Roo se velt School, Danbury WCSU, Waterbury

Bank Street , and New Haven Criscuolo Park collocated . Thus, the NCore and near

- road manual FRM

primary samplers will operate on the 3

- day schedule, while the remainder would be on the 6

- day

schedule.

### 40 CFR 58 Appendix D 4.7 for PM 2.5 monitoring require at least one monitor in a Metropolitan Statistical Area (MSA) having a population

between 500,000 and 1,000,000 where design values are below 85 percent of NAAQS. Therefore, for the

Bridgeport

- Stamford

- Norwalk MSA, which has a 2013 estimated population of about 940,000 andConnecticut 2015 Annual Air Monitoring Network Plan 14

maximum annual and 24

- hour design values of 9.3 μ g/m 3 and 24 μ g/m 3 , respectively, DEEP propos es to

terminate the Westport monitor. Westport PM 2.5 has the lowest design values (7.7 and 21 μg/m 3 ) and is

less indicative of population exposure than the other monitors (Danbury and Bridgeport) within the MSA

.

### FRM Network

DEEP operates four PM 10 FRM sites in the air

monitoring network using Thermo Partisol®

-

Plus 2025 /2025i sequential air samplers

(RFPS

- 1298

- 127)

. The two NCore sites,

Cornwall and New Haven, operate on a 1

- in

- 3

day sample schedule, while Bridgeport and

East Hartford are operated on a 1

- in

- 6 day

sample schedule. T he New Haven NCore site

has a collocated PM 10 FRM sampler operating

on a 1

- in

- 6 day sample schedule. In addition

to the FRM PM 10 monitors, three sites

, Cornwall Mohawk Mountain , New Haven

Criscuolo Pa rk and Hartford Huntley Place,

have FEM Met One BAM 1020 continuous

PM10 monitors (EQPM

- 0798

- 122 )

. All sites

that have PM 10 FRM samplers are paired with

PM 2.5 FRM samplers for coarse PM ( PM 10

- 2.5 )

. Coarse PM is defined as thoracic PM having

particle aerodynamic diameters between 2.5

and 10 microns. No changes to this network

are proposed through the end of 201 6

.



### PM Speciation Network

PM 2.5 chemical speciation measurements are

obtained at five sites in the DEEP air

monitoring network. These include filter

based daily composite 1

- in

- 3 day samples at

the NCore sites, and continuous hourly black

carbon at five sites.

The Interagency Monitoring of Protected

Visual Environments ( I MPROVE ) monitor is

located at the Cornwall site and the Che mical

Speciation Network ( CSN ) monitor is at the

New Haven Criscuolo Park site. Both sites

are operated on the standard EPA PM 1

- in

- 3

day sample schedule and provide 24

- hour

integrated filter

- base measurements.

Black carbon (BC) and ultra

- violet channel

carbon ( UVC )

, a wood smoke PM surrogate,

are monitored at the Criscuolo Park,

Cornwall , Hartford

, East Hartford McAuliffe

Park and Danbury WCSU sites using 7

-

channel TAPI Model 633 a ethalometers. No changes are propos ed to the PM speciation network during

2015

- 2016

.Connecticut 2015 Annual Air Monitoring Network Plan 16



### Ozone Network

DEEP operates eleven ozone sites in the

air monitoring network. The ozone

analyzers at the Cornwall and New

Haven Criscuolo Park sites are operated

year

- round, while the remaining sites

are operated from April 1 through

September 30. In addition to the DEEP

network, EPA operates a seasonal

ozone monitor in Abington (Pomfret) as

part of its Clean Air Status and Trends

(CASTNET) netwo rk.

Ozone monitoring in the DEEP network

is conducted using Teledyne

- API Model

T400 UV photometric ozone analyzers

(method EQOA

- 992

- 087)

. Ozone

measurements are sent to the EPA

AIRNow website for AQI purposes on an

hourly basis

. No changes to the ozone

monitoring network are planned

through the end of 201 6

.



### PAMS Network

DEEP currently operates two

Photochemical Assessment Monitoring

Stations (PAMS) sites in the air

monitoring network. PAMS

measurements are obtained from June

1 through August 31 each year. PAMS

sampling generates hourly

measurements of 34 volatile organic

compounds (VOCs) that are

considered to be important precursors

to ozone formation

. Many of these

compounds are also ide ntified as

hazardous air pollutants (HAPs)

. T wo Synspec Gas Chromatographs (FID

and PID detectors) are deployed at

the East Hartford McAuliffe Park and

New Haven Criscuolo Park sites.

A third site, Westport Sherwood Island

State Park, was discontinued at the

end of 2014 with EPA Region 1

approval; however, this change in the PAMS network is formally requested in this Network Plan.

The East Hartford and New Haven sites have on

- site surface meteorological monitoring, and New Haven

has a ceilometer (Vaisa la CL

- 51) that measures boundary layer height. Additional upper air

measurements for ozone transport modeling are obtained from regional National Oceanic and

Atmospheric Administration (NOAA) radiosond e s

. Carbonyl sampling at East Hartford was suspended for

2013

- 2014 and will continue to be suspended for 201 6 due to a re

- prioritization of limited funding

resources

. No further changes to the PAMS monitoring network are anticipated through the end of 201 6

.Connecticut 2015 Annual Air Monitoring Network Plan 17



### NO 2 

### Network

DEEP operates four nitrogen

oxide/ nitrogen dioxide / total oxides of

nitrogen ( NO/ NO 2 /NO X or NO X ) sites in

the air monitoring network. All NO X analyzers are Teledyne

- API Model T200U

(RFNA

- 1194

- 099 ) and are operated

year

- round

. DEEP also operates two

nitrogen oxide/total reactive oxide s of

nitrogen (NO/NO Y ) TAPI model

T200U/501 monitors

, at Cornwall

Mohawk Mt and New Haven Criscuolo

Park

, as part of NCore requirements

. NO Y

is defined as N O+NO 2 +NO Z, where NO Z represents higher oxides of nitrogen

. The

NO/NO 2 /NO X monitor at Westport was

discontinued at the end of 2014

, along

with PAMS VOCs

, wit h initial EPA Region

1 approval; however, this change is

formally proposed in this Network Plan.

The NO/NO 2 /NO X and NO/NO Y networks

fulfill requirements for PAMS, NCore and

SLAMS monitoring of these parameters. These requirements include: near

- road NO 2 monitoring

(Hartford), area

- wide NO 2 monitoring (East Hartford), nationwide NO

2 monitoring for susceptible and

vulnerable populations (New Haven), NCore NO/NO Y monitoring (Co rnwall and New Haven), PAMS

NO/NO 2 /NO X monitoring (East Hartford and New Haven) and NO/NO Y monitoring at one PAMS site (New

Haven). In addition, NO/NO

2 /NO X is monitored at Cornwall to complement and support NO/NO Y monitoring.

Nitrogen oxide and total reac tive oxides of nitrogen (NO/NO Y ) monitoring is required at one of the PAMS

sites (in addition to NCore) , which should be either an upwind background (Type 1) o r a maximum ozone

(Type 2 or Type 3) site

. The New Haven Criscuolo Park site monitor is intended to satisfy the PAMS

requirement for NO/ NO Y at a Type 2 PAMS site

.

Aside from discontinuing monitoring at Westport, no further changes to the NO X network are proposed for

the period 2015

- 2016. However, the recent NO 2 NAAQS rule changes (January 22, 2010, revised March

7, 2013) would require near

- road NO 2 monitoring in the Bridgeport

- Stamford and New Haven

- Milford

MSAs by January 1, 2017. As such, planning for these monitors would begin in late 2015, but

implementation would be dependent on EPA funding.



### CO Network

DEEP operate s five carbon monoxide (CO)

sites in the air monitoring network. All CO

samplers are operated year

- round and

employ TE 48i

- TLE analyzers (RFCA

0981

- 054)

. Of the 5 sites, New Haven

and Cornwall comply with the requirement

for CO monitoring at NCore sites

, Hartford

and Bridgeport monitor under CO limited

maintenance plans , and East Hartford and

New Haven include CO as a complement

to PAMS monitoring.

EPA’s most re cent revision to the CO

NAAQS rule, finalized August 12, 2011,

specifies CO monitoring collocated with

NO 2 near

- road monitors in CBSAs with

pop ulations greater than 1,000,000. This

requirement applies to the Hartford

- West

Hartford

- East Hartford M SA. COConnecticut 2015 Annual Air Monitoring Network Plan 18

monitoring at the Huntley Place site meets the local monitoring requirement for DEEP’s Hartford area C O

limited maintenance plan ( DEEP, 2004 )

, as well as the near

- road CO monitoring requirement

. No changes

to the CO monitoring network are anticipated through the end of 201 6

.



### SO 2 

### Network

DEEP operates f our sulfur dioxide (SO

2 ) sites in the air monitoring network. All samplers are TE 43i

- TLE

SO 2 analyzers (EQSA

- 0486

- 060) and are operated year

- round. Both 1

- hour and 5

- minute block average

SO 2 data are validated and reported to EPA.

The Bridgeport Edison School and the East

Hartford McAuliffe Park SO 2 monitors continue to

satisfy the requirements of the J une 2, 2010 SO 2

final NAAQS rule 2 for population

- weighted

emissions index (PWEI) monitoring in the

Bridgeport

- Stamford

- Norwalk and Hartford

- East

Hartford

- West Hartford CBSAs, respectively . In

addition, SO 2 monitoring is required at both the

Cornwall Mohaw k Mountain and the New Haven

Criscuolo Park NCore sites.

EPA’s June 2010 SO 2 final NAAQS rule and

subsequent proposed SO2 data requirements

rule 3 , proposed on May 13, 2014, indicate that,

in addition to design values from NCore and

PWEI

- required monitoring, EPA may use refined

dispersion modeling and/or source monitoring for

SO 2 attainment designations based on source emissions and area population thresholds

. Although not

likely b ase d on proposed source thresholds, it is possible that additional (source) monitoring may be

required by the final rule. No changes to the SO 2 monitoring network are anticipated through the end of

201 6

.



### Lead (Pb) Network

The DEEP Pb monitoring network co nsists of

primary 1

- in

- 6 day and collocated 1

- in

- 12 day

sampling at the New Haven Criscuolo Park

urban NCore site in fufillment of the revised

Pb NAAQS and monitoring requirements

promulgated in December 2010. No additional

Pb monitors are required for sta tionary source

or airport monitoring as required by the rule

. 4

2 Lead measurements are obtained from

Energy Dispersive X

- Ray Fluorescence (XRF)

analysis of the 47 mm Teflon filter samples

collected using a low

- volume (lo

- vol) FRM

R&P Partisol Plus 2025 PM 10 Sequential Air

Samplers. Although the Pb NAAQS is defined

as 0.1 5 μg/m 3 lead in total suspended

particulates (TSP) , Pb monitoring regulations

allow surrogate monitoring of Pb in PM 10 , providing that design values are below two

thirds of the NAAQS, or 0.1 0 μg/m 3 . New Haven Pb values continue to remain w ell below this threshold,

with a 201 4 design value of 0.04 μg/m 3 , while most monthly averages are in the range of 0.00

- 0.01

μg/m 3
