                       2007 ANNUAL REPORT ON AIR QUALITY

                                   IN NEW ENGLAND

This report provides a summary of 2007 annual air quality information for all states in New
England. The majority of the data included in this report were submitted to EPA by the states
from their ambient monitoring networks in accordance with 40 CFR 58. The only data from
industrial monitors which have been included are from the Massachusetts Industrial Network.
These industrial sites supplement the state network.

This report reflects the status of the AQS database as of May 2008. The majority of data used
have been evaluated and verified by EPA. However, for those monitors that appear to be violating
an applicable ambient air quality standard, the data may require further evaluation by both EPA
and the states. EPA had designated areas in New England as non-attainment for the 1997 8-hour
ozone standard and the 1997 annual PM2 5 standard. Designations for the 2006 PM2 5 24-hour
standard will be issued in December 2008. Designations for the 2008 ozone standard have not yet
been made. Statements in this report relative to ozone exceedances and violations are in relation to
the 0.08 Standard which was in effect in 2007.

A table of the National Ambient Air Quality Standards (NAAQS) follows this introduction.

There is a list of potential health effects of the criteria pollutants after the NAAQS.

The following table lists, by state, a summary of criteria pollutant data  from sites in each state in
New England, and from industrial sites in Massachusetts. The information presented compares the
measured values to each NAAQS; it includes the number of violations, the maximum and second
high values,  and the  annual means (arithmetic mean or average for SO2, PM10 and NO2). An
annual mean is not valid for intermittent data unless there are four valid quarters. For PM10 and
PM2 5, 75% of the scheduled samples must be available for a quarter to be considered valid.  For
continuous data, 75% of the year must be available to calculate a valid annual average. However,
years with at least 11 samples in each quarter shall be considered valid, notwithstanding quarters
with less than complete data, if the resulting annual mean is greater that the level of the standard.

Included with this table are graphs of selected air quality monitoring sites that show a multi-year
span of data  for PM10, CO, PM2 5, SO2, and NO2.  For hourly ozone, there is a graph of the number
of days ozone exceeded 0.125ppm.

The State maps  display the location of the monitoring sites (when measuring particulates, each
state has at least one location where duplicate, or co-located, monitors run side by side for quality
assurance purposes.)

Additional maps are provided to show the current areas in New England designated non-
attainment by EPA.  This is followed by a summary of information from the Performance
Evaluation Program  Audits.

The last section provides a list of AQS state and regional Air Quality Contacts, their addresses and
phone numbers.

The Clean Air Act which was last amended in 1990, requires EPA to set National Ambient Air Quality
Standards (40 CFR part 50) for pollutants considered harmful to public health and the environment. The
Clean Air Act established two types of national air quality standards. Primary standards set limits to protect
public health, including the health of "sensitive" populations such as asthmatics, children, and the elderly.
Secondary standards set limits to protect public welfare, including protection against decreased visibility,
damage to animals, crops, vegetation, and buildings.
The EPA Office of Air Quality Planning and Standards (OAQPS) has set National Ambient Air Quality
Standards for six principal pollutants, which are called "criteria"  pollutants. They are listed below. Units of
measure for the standards are parts per million (ppm) by volume, milligrams per cubic meter of air (mg/m3),
and micrograms per cubic meter of air (|ig/m3).

                   Health Effects of Criteria Pollutants

Lead (Pb)

Brain damage, kidney damage, and gastrointestinal distress are seen from short-term exposure to high levels of lead.
Long-term exposure to lead in humans results in effects on the blood, central nervous system, blood pressure,
kidneys, and Vitamin D metabolism. Children are particularly sensitive to the chronic effects of lead, with slowed
cognitive development, reduced growth and other effects reported. The major sources of lead air pollution are lead
smelters and battery manufacturing plants.

Ozone (O3)

Ozone  can irritate the respiratory system, causing coughing, throat irritation, and/or an uncomfortable sensation in
the chest. Ozone can reduce lung function and make it more difficult to breathe deeply and vigorously. Ozone can
aggravate asthma and increase susceptibility to respiratory infections. It injures vegetation, and has adverse effects
on materials. Ozone is generally highest on sultry summer afternoons. Ozone is formed in the atmosphere by the
reaction of nitrogen oxides, and hydrocarbons in the presence of sunlight.

Sulfur Dioxide (SO2)

Children and adults with asthma who are active outdoors are most vulnerable to the health effects of sulfur dioxide.
The primary effect they experience, even with brief exposure, is a narrowing of the airways, which may cause
symptoms such as wheezing, chest tightness, and shortness of breath. Long-term exposure to both sulfur dioxide and
fine particles can cause respiratory illness, alter the lung's defense mechanisms, and aggravate existing
cardiovascular disease.  It combines with water to form acid aerosols and sulfuric acid mist which falls to earth as
acid rain, causing plant and structural damage, and acidifying watershed and freshwater ecosytems. Major sources
include power plants and industrial boilers.

Nitrogen Dioxide (NO2)

In children and adults with respiratory disease, nitrogen dioxide can cause respiratory symptoms such as coughing,
wheezing, and shortness of breath, and affect lung function. In children, short-term exposure can increase the risk of
respiratory illness. Studies suggest that long-term exposure may cause permanent structural changes in the lungs.  It
also combines with water in the atmosphere to form acid aerosols and contributes to acid rain causing watershed
acidification and damage to material structures. The sources of nitrogen dioxide are motor-vehicle exhaust, and fuel
combustion sources such as electric power generating facilities.

Carbon Monoxide (CO)

People with cardiovascular disease, such as angina,  may experience chest pain and more cardiovascular symptoms if
they are exposed to carbon monoxide, particularly while exercising. In healthy individuals, exposure to higher levels
of carbon monoxide can affect mental alertness and vision. Carbon monoxide forms when carbon and hydrocarbon in
fuels do not  completely burn. Motor vehicles are the most significant source.

Paniculate Matter (PM2 5 and PM10)

Both fine and coarse particles can accumulate in the respiratory system. When exposed to paniculate  matter (PM),
people  with existing heart or lung problems are at increased risk of premature death or admission to hospitals or
emergency rooms. Children and people with existing lung disease may not be able to breathe as deeply or vigorously
as they would normally, and they may experience coughing and shortness of breath symptoms. PM can increase
susceptibility to respiratory infections and can aggravate existing respiratory diseases, causing more use of
medication and more doctor visits. PM includes both solid particles and liquid droplets found in air. Many manmade
and natural sources emit PM directly or emit other pollutants that react in the atmosphere to form PM. Sources of
fine particles include all types of combustion (motor vehicles, power plants, wood burning, etc.) and some industrial
processes. Sources of coarse particles include crushing or grinding operations, and dust from paved or unpaved
roads.

                2007  Summary of New England Ambient Air Quality
2007 Summary of Ambient Air Quality in New England
The New England states operate more than 110 criteria pollutant monitoring sites, with more than 250 ambient air quality
monitors. These monitors measure the criteria pollutants: carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide
(NO2), ozone (O3), lead, and paniculate matter (PM10 and PM2 5).  Levels of these pollutants are compared to the National
Ambient Air Quality Standards (NAAQS), limits set by EPA to protect public health and welfare. In addition, more than a
dozen sites measure precursor pollutants for ozone (PAMS sites) and toxic compounds.

In general, air quality measurements are strongly influenced by seasonal weather patterns.  This is especially true for
ozone and haze (principally composed of fine paniculate matter - PM^ 5) which can be influenced by photochemical and
transport mechanisms. For these pollutants, higher ambient air concentrations are generally recorded during warm and dry
summers and lower concentrations during cool and/or wet summers. In addition, high PM2 5 concentrations can be
recorded during strong temperature inversions in the winter months. Both of these pollutants are tracked real-time by the
EPA AIRNow Air Quality Index (AQI) program, which maps the relative health impacts of ozone and fine paniculate
concentrations throughout the U.S. (http://www.airnow.gov/).

During 2007, weather conditions during the summer favored warmer and drier conditions.  Concentrations of ozone and
fine particles were higher at sites in southern New England than in northern New England. Using the number of days
when at  least one ozone monitoring site exceeded the NAAQS 8-hour ozone concentration of 0.085 ppm, the 2007 ozone
season was comparable to 2005 (26 days), but not similar to 2006 (16 days), 2004 (13 days), or 2003 (15 days), with 27
exceedance days.. The highest 8-hour ozone concentration was measured in Connecticut (0.123 ppm). The other New
England states measured maximum 8-hour concentrations ranging from 0.112 ppm (MA) to 0.086 ppm (VT). Twenty-
three (23) monitoring sites in New England exceeded the fourth highest 8-hour ozone threshold (> 0.085 ppm).  This
compares with previous years: 2006 - 14 monitoring sites, 2005 - 22 sites, 2004 - 2 sites, and 2003 - 14 sites. Vermont
was the only state in New England that has not exceeded the fourth highest 8-hour ozone standard of 0.085ppmduring the
five-year period from 2003 - 2007.

Since 1993, the New England states (except Vermont)  have operated Photochemical Assessment Monitoring Stations
(PAMS), which measure ozone precursors (oxides of nitrogen and organic compounds). The 2007 PAMS data indicate
that the highest concentrations of organics, measured as Total Non-Methane Organic Compounds (TNMOC), were
recorded at the New Haven (CT) Type 2  urban site.  The lowest concentrations were recorded at the far downwind sites
located in Maine (Cape Elizabeth and Acadia National Park).  In general, TNMOC concentrations remained below those
measured during the  1990's, but were similar to the last five years of measurements.

During 2007, the highest daily concentrations of fine paniculate matter PM2 5 (on the order of 40-50 ug/m3) were
measured at sites in Massachusetts, Connecticut and Rhode Island.  No sites exceeded either the 24-hour or the annual
NAAQS. The highest annual average concentrations for fine paniculate matter (>12 ug/m3, but <13  ug/m3) were
measured at Springfield (MA), Bridgeport (CT) and New Haven (CT). The lowest annual average concentrations of fine
paniculate matter were measured at the Bar Harbor and Greenville  (ME) sites (<6.0 ug/m3).  For coarse paniculate matter
(PM10), the highest daily concentration was measured at the Madawaska (ME) site (106 ug/m3). None of the PM10 sites in
New England exceeded either the primary or the secondary NAAQS for PM10.

In general, the concentrations for all of the other criteria pollutants (SO2, NO2, CO, and lead) measured at monitoring sites
throughout New England either declined or remained at historically low levels. The only exception was the Pembroke
(NH) site which continued to measure increasing concentrations of SO2 (five-year trend). However, the SO2
concentrations for this site, and the other SO2, NO2, CO,  and lead sites in New England were well below the NAAQS.

Seven carbon monoxide (CO) ambient monitoring sites operated in 2007, three of which are trace CO
ambient monitoring sites.  No exceedance or violation of the 1-hour or 8-hour CO NAAQS were recorded in
Connecticut during 2007.  The highest recorded maximum 8-hour concentration of 3.4 ppm was recorded at
the Hartford Courthouse site.  This contrasts with previous 8-hour maximum measurements in 2006 (4.4
ppm), 2005 (5.4 ppm), 2004 (5.7 ppm), 2003 (5.7 ppm) and 2002 (5.7 ppm), 2001 (6.1 ppm), and 2000 (8.5
ppm). The trend graph shows for the past twenty four years CO concentrations are well below the national
standards and indicate a downward trend in concentration.

The four nitrogen dioxide (NO2) ambient air monitoring sites that operated during 2007, did not measure any
violation of the NAAQS.  The New Haven site reported the highest annual arithmetic mean NO2
concentration of 0.018 ppm, which is 34% of the NAAQS.  The Photochemical Assessment Monitoring
Stations (PAMS) located in East Hartford and Westport both reported concentrations of NO2 well below the
NAAQS. The trend graph shows for the past twenty four years annual concentrations of NO2 have been
relatively constant  with a slight downward trend since 2001.

During 2007, nine of the twelve ozone monitoring sites reported a fourth-highest daily 8-hour average ozone
concentration above the level of the 8-hour NAAQS. In 2006 and 2005 ten sites recorded values above this
level. In 2004, only 1 site recorded a value above this level.  In 2003, ten of the eleven ozone monitoring
sites recorded fourth high values above this level. In 2007, the highest 8-hour ozone concentration of 0.123
ppm was measured at the Cornwall site.  The highest 8-hour ozone concentration in 2006 was recorded at
the Westport site at 0.119 ppm.

The six sites measuring particulate matter of less than 10 microns (PM10) did not record an exceedance or
violation of the 24-hour NAAQS during 2007. The Bridgeport site reported the highest 24-hour second
maximum value of 43 ug/m3 during 2007, which is 28% of the NAAQS.  The other five monitoring sites
reported highest 24-hour second maximum values of 42 ug/m3, 36 ug/m3, 35 ug/m3, 30 ug/m3 and 28 ug/m3
in 2007.

In 2007, Connecticut operated a network of fourteen fine particulate matter (PM25) sites.  During 2007, the
annual arithmetic mean concentration of PM2 5 was the highest at the Bridgeport site with a value of 12.66
|ig/m3. The highest 98th percentile 24-hour value was 32.7 |ig/m3 recorded at the Waterbury site.  The nine
year annual arithmetic mean concentration trend graph shown for the Bridgeport, Westport, New Haven
State Street, Danbury and East Hartford McAuliffe Park sites have remained relatively flat, except for a
slight increase during 2005.

Nine air quality monitoring sites measured sulfur dioxide (SO2) in Connecticut during 2007, three of which
are trace SO2 ambient monitoring sites.  There were no exceedances or violations at any of the Connecticut
ambient monitoring sites for the annual, 24-hour, or 3-hour SO2 NAAQS. The New Haven-James Street site
reported the highest arithmetic mean concentration of SO2 at 0.0042 ppm, which is 14% of the NAAQS.
The highest 24-hour second maximum concentration of 0.020 ppm and the highest 3-hour second maximum
concentration of 0.065 ppm were also recorded at the New Haven site. The long range trend for SO2
concentrations in Connecticut continually shows a downward trend.

In 2007, the state of Maine operated two low-level, highly sensitive carbon monoxide (CO)
monitors - one at the Cape Elizabeth - Two Lights State Park Photochemical Assessment
Monitoring Station (PAMS) site, and the other at the Bar Harbor  - McFarland Hill Acadia National
Park site. CO measurements were recorded at these sites to help understand ozone formation,
summer photochemistry, and pollution transport along the Maine coast.

During 2007, only one of Maine's seventeen ozone (O3) monitoring sites recorded a fourth highest 8-hr
average ozone concentration above the level of the 8-hr NAAQS. The Bar Harbor - Cadillac Mountain site
recorded a value of 0.086 ppm.  The Cape Elizabeth - Two Lights State Park and the Kennebunkport -
Ocean Ave. / Parsons Way sites recorded the highest 8-hour ozone concentration at 0.099 ppm.  The Bar
Harbor - Cadillac Mountain site recorded  a value of 0.098 ppm. O3 levels in 2007 were similar to those in
2006.

None of Maine's parti culate matter sites which measured particles of 10 microns or less (PM10) reported any
exceedances of the 24-hour NAAQS during 2007. The highest 24-hour PM10 concentration was recorded at
the Presque Isle -Riverside St. monitoring site at 106 ug/m3.  The Portland - Tukey's Bridge site recorded
the highest annual weighted arithmetic mean PM10 concentration at 24.9 |ig/m3.

Maine began monitoring for fine particulate matter (PM2 5) in 1999.  During 2007, there were ten PM2 5
monitoring sites. Data from the sites indicate that none of the sites have recorded PM2 5 concentrations that
would result in an exceedance or violation of either the 24-hour or the annual NAAQS for PM2 5. The
Portland - Tukey's Bridge site recorded the highest weighted arithmetic mean at 10.15 jig/m3. The
Madawaska - Tang's Palace site recorded the highest 24-hour value at 34.8 jig/m3.

In 2007, there were no exceedances or violations of the sulfur dioxide (SO2) NAAQS at the only SO2
monitoring site. The Bar Harbor  - McFarland Hill site 3-hour, 24-hour, and arithmetic mean SO2
concentrations were 0.006 ppm, 0.006 ppm, and 0.0005 ppm respectively, all well below the standards.  The
trend for SO2 concentrations is well below the NAAQS and shows small year-to-year changes.

Massachusetts operated five carbon monoxide (CO) ambient monitoring sites in 2007.  The five sites are
located in Boston (one at Kenmore Square and one at Harrison Ave - Roxbury), Springfield (Liberty Street),
Worcester (Summer Street), and Lowell (Old City Hall). No exceedances of the 8-hour National Ambient
Air Quality Standards (NAAQS) for CO have been recorded at any site in Massachusetts since 1996. The
twenty-three year trend graph of second maximum 8-hour CO concentrations in Massachusetts generally
shows an average decrease of more than 6 ppm over the twenty-four year period at each of the five sites
included in the analysis. The highest 8-hour value was recorded at the Lowell site and was 2.1 ppm. The
2nd highest 8-hour value was recorded at the Worcester Summer St. site and was 1.7 ppm.

   Nitrogen dioxide (NO2) measurements were made at 12 monitoring sites in Massachusetts during 2007.
   The highest 1-hour concentrations of NO2 were recorded at monitors in Boston, Springfield and
   Worcester.  The lowest 1-hour concentration was measured at the Newbury site.  The highest annual
   mean NO2 concentration was recorded at Kenmore Square (0.0206 ppm) and the lowest concentration
   was at Newbury (0.0034 ppm). A generally downward trend in NO2 concentration can be detected in the
   twenty-four year trend data.

In 2007, nine of the sixteen ozone monitoring sites recorded a fourth highest 8-hour average ozone
concentration at or above the level of the 8-hour NAAQS. Generally, years that have many days with
temperatures above 90° F, as in 1988, 1993 and 2002, have higher ozone levels while years that are cool
and/or wet as in 2003, 2004 and 2005 tend to have lower ozone levels.

In 2007, Massachusetts maintained seven ambient monitoring sites measuring particulate matter less than 10
microns (PM10). The highest 24-hour PM10 concentration was recorded at the Worcester Summer St. site
(57 |ig/m3).  The lowest 24-hour maximum concentration was measured at the Quabbin Summit site and was
recorded as 31 jig/m3. Over the past twenty-one years PM10 levels have shown significant year to year
variability especially for the 24-hour sampling period. However, overall PM10 levels do not appear to trend
up or down during the time period.

Massachusetts operated a network of sixteen fine particulate matter (PM2 5) ambient monitoring sites in
2007. The highest 24-hour concentration was recorded at the Boston North St. site and measured 50.2
|ig/m3. The highest annual weighted arithmetic mean was calculated at the Springfield Liberty site and
measured 12.22 jig/m3.  Since 1999, a slight downward trend can be seen in the data.

Ten sulfur dioxide (SO2) monitoring sites were operated in Massachusetts during 2007.  No exceedance or
violation of the annual or 24-hour (primary) or the 3-hour (secondary) NAAQS for SO2 was recorded in
2007. The highest 3-hour and 24-hour SO2 concentrations, along with the highest annual arithmetic mean,
were recorded at the Boston North St. site and measured 0.092 ppm, 0.054 ppm and 0.0056 ppm,
respectively.  All  SO2 trend sites in Massachusetts have shown a general decline in concentrations over the
past twenty-four years.

As has been the case for over a decade, in 2007 there were no violations of either the 8-hour or 1-hour
National Ambient Air Quality Standard (NAAQS) for carbon monoxide (CO) at the two CO monitoring sites
in New Hampshire. The last exceedances of the 8-hour CO NAAQS occurred in Manchester (13.5 ppm)
during the winter of 1996. In 2007, Manchester reported a second maximum 8-hour average CO
concentration of 1.8 ppm, which was less than 15% of the standard. The Nashua site recorded a second
maximum 8-hour average CO concentration of 2.2 ppm.  The most recent ten year trend for CO indicates
that the CO levels show relatively small year-to-year fluctuations, but tend to be falling and well below the
NAAQS.

In 2007, nitrogen dioxide (NO2) was measured at four monitoring sites. The Portsmouth and
Manchester monitoring sites recorded the highest NO2 concentrations, but well below the standard.
The ten-year trend in NO2 indicates that there has been no recent upward or downward trend in
concentration.

Two of the thirteen ozone monitors in New Hampshire violated the 8-hour ozone standard. In 2007, the
maximum 8-hour average ozone concentration occurred at the Seacoast Science Center in Rye (0.097 ppm).
The Pack Monadnock Summit PAMS monitoring site recorded the second highest maximum 8-hr ozone
concentration (0.094 ppm)

None of the two coarse particulate matter (PM10) monitoring sites in New Hampshire (Portsmouth and
Manchester) exceeded or violated the annual or 24-hr NAAQS for PM10 over the past ten years (1998-2007).
The highest 24-hour concentration in 2007 was recorded in Manchester (41 ug/m3 each - less than 30% of
the NAAQS).  The highest maximum annual average PM10 concentration was recorded in Manchester (14.7
ug/m3, <30% of the NAAQS). Over the past ten years, all of the PM10 monitors in New Hampshire recorded
PM10 concentrations well below the national standards. PM10 concentration variability is common, due to
differences in weather and local  PM10 emissions.

In 1999, New Hampshire established a network of fine particulate monitors (PM2 5). By 2003, eleven
monitoring sites provided data on the concentration of PM2 5 in the state.  Over the past several years the
highest concentrations of PM2 5 have been in the Nashua and Keene urban areas.  During 2007, relatively
high concentrations of fine parti culate matter (PM2 5 - [FRM - Federal Reference Method] annual weighted
arithmetic mean) were recorded at the Railroad Street site in Keene (10.84 ug/m3), and at the Crown Street
site in Nashua (10.26 ug/m3), compared with the other seven New Hampshire monitoring sites. These
concentrations were well below the primary standard for PM2 5 which is 15 ug/m3.

 No exceedance or violation of the 1-hour or 8-hour carbon monoxide (CO) NAAQS was recorded
 at the two CO monitoring sites in Rhode Island during 2007.  The Dorrance Street Site in
 Providence reported the highest 8-hour second maximum CO level of 2.5 ppm, which was the
 same value reported in 2004, 2005 and 2006.  Over the past six years the highest 8-hour second
 maximum concentration of CO at this site was 2.7 ppm, which occurred in 2002.  Lower
 concentrations of CO were recorded at the East Providence Site with the highest 8-hour second
 maximum concentration within the past six years of 2.6 ppm occurring in 2002.  The 24 year
 trend of CO concentrations shows a downward trend with concentrations leveling off between
 2003 and 2007.

    Rhode Island operated three nitrogen dioxide (NO2) monitoring sites during 2007. NO2
    monitors were located at two Photochemical Assessment Monitoring Stations (PAMS)
    Sites that operated during June, July and August and at the Rockefeller Library in
    Providence which operated all year. This latter site recorded the highest annual arithmetic
    mean NO2 concentration of 0.014 ppm, which is lower than the previous year of 0.015 ppm
    and 26% of the NAAQS. The 24 year NO2 concentration trend at the Rockefeller Library
    Site has remained relatively flat with a slight decreasing trend beginning in 2000. Each
    year, over the past eight years, the mean NO2 concentration during the PAMS season has
    been three to five times higher at the Francis School  Site (0.005 - O.Olppm) compared to
    the Alton Jones Site (0.001 - 0.003 ppm).

None of the particulate matter (PM10) sites in Rhode Island had any exceedances or violations of the 24-hour
standards over the past seven years. Of the four PM10 monitoring sites, the Vernon Street Site in Pawtucket
reported the highest 24-hour second maximum value of 52 |ig/m3 during 2007. The other three monitoring
sites reported the highest 24-hour second maximum values of 24 |ig/m3, 27 |ig/m3 and 29 |ig/m3 in 2007.
The long range graphs for PM10 show values varied up and down from year-to-year with no signs of an
upwind or downwind trend. However, there was a significant decline of the highest 24-hour second
maximum value at the Dorrance Street and Prairie Avenue sites in Providence during 2007 compared to
2006.

In 2007, Rhode Island operated a network of five fine particulate matter (PM2 5) sites.  During 2007, the
annual arithmetic mean concentrations of PM2 5 were highest at the Providence area sites (i.e. Francis
School, Prairie Ave., Vernon St., and Eddy St.) compared to the rural site at Alton Jones. The nine year
concentration trends for the Alton Jones, Francis School, Prairie Ave., and Vernon Street Sites have
remained relatively flat, except for a slight increase at the Vernon Street Site during 2005.  The 2006
and 2007 concentrations at the Vernon Street Site went back to similar levels seen in 2004.

  Two air quality monitoring sites measured sulfur dioxide (SO2) in Rhode Island during 2007. There were
  no exceedances or violations of the annual, 24-hour, or 3-hour NAAQS. The Dorrance Street Site in
  Providence reported the highest arithmetic mean concentration of SO2 at 0.005 ppm, which is 17% of the
  NAAQS.  The highest 24-hour second maximum concentration of 0.018 ppm and the highest 3-hour
  second maximum concentration of 0.039 ppm were recorded at the Rockefeller Library Site in
  Providence. The long range trend for SO2 concentrations in Rhode Island continually shows a downward
  trend.

The state of Vermont operated two carbon monoxide (CO) ambient monitoring sites during 2007, one in
Rutland and one in Burlington.  No exceedance or violation of the 1-hour or 8-hour CO National Ambient
Air Quality Standards (NAAQS) was recorded at either of the two monitoring sites during 2007. The
greatest first and second highest 8-hour concentrations of CO were recorded at the Rutland site. These
values were 2.6 ppm and 1.7 ppm, respectively.  A general decline is shown in the 24 year trend of CO
concentrations in Vermont.

Two nitrogen dioxide (NO2) monitoring sites (Rutland and Burlington) were operated by the state during
2007. No exceedances of the NAAQS for NO2 were recorded for either site. The past 23 years of NO2 data
indicate that the concentrations of NO2 have remained relatively steady with a slight decrease in the past few
years. These concentrations are very low in comparison with the NAAQS.  During 2007, the highest annual
arithmetic mean concentration of NO2 in Vermont was measured at the Burlington site.  This value was
0.0111 ppm, which is approximately 21% of the NAAQS.

Neither of the two ozone monitoring sites in Vermont (Underhill and Bennington) recorded a fourth highest
8-hr average ozone concentration above the level of the 8-hr ozone NAAQS. The highest 8-hour average
ozone concentration in Vermont during 2007 was recorded at the Underhill site and was 0.086 ppm.

During 2007, Vermont maintained four ambient monitoring sites measuring particulate matter less than 10
microns (PM10).  The sites include Underbill, Burlington, Rutland and Brattleboro. The two special purpose
monitoring sites, operating in Shoreham for the past few years, were discontinued at the end of 2006.  Data
for 2007 continued the 12 year trend of low PM10 concentrations recorded by Vermont monitoring sites.
The highest 24-hour PM10 concentration in the state was recorded at the Brattleboro ambient monitoring site
and measured 34 jig/m3.  The Brattleboro site also recorded the highest annual weighted arithmetic mean
PM10 concentration of 15.5 |ig/m3. These concentrations were well below the NAAQS for PM10. The
lowest 24-hour PM10 maximum value concentration was measured at the Underbill ambient monitoring site
and was recorded as 26 jig/m3.  The lowest PM10 annual weighted arithmetic mean concentration was also
measured at the Underhill  site and was recorded as 8.1 jig/m3.

Vermont operated a network of four fine particulate matter (PM2 5) ambient monitoring sites in 2007.  The
sites include Bennington, Underhill, Burlington and Rutland.  The two special purpose monitoring sites,
operating in Shoreham for the past few years, were discontinued at the end of 2006. PM2 5 concentrations in
Vermont have historically been below the NAAQS. The Rutland site recorded the highest annual weighted
arithmetic mean for a POC 1 monitor (Parameter Occurrence Code). This value was 10.95 |ig/m3.

The state operated one sulfur dioxide (SO2) ambient monitoring site during 2007, located in Rutland. The
highest 3-hour SO2 concentration at the site was 0.047 ppm.  The highest 24-hour average SO2 concentration
was 0.028 ppm and the annual arithmetic mean was 0.0046 ppm. With the exception of 1994, the historical
data indicate a general decline in the concentration of SO2 in the state of Vermont.

The PM2 5 Performance Evaluation Program (PEP) is part of a National Quality Assurance Program for PM2 5. Its purpose is to
determine total bias for the PM2 5 sample collection and laboratory analysis processes.  EPA contractors collocate portable
federally referenced PM2 5 samplers adjacent to states' routine PM2 5 samplers.  The instruments run for a 24-hour period at the
states' monitoring sites. Once the run is completed in Region I, the PM2 5 PEP filters are sent to an independent EPA East Coast
Weighing Laboratory in Region IV where PM2 5 concentrations are determined and compared in order to assess bias.  Statistical
analyses are conducted between EPA's data and the states' data in order to decide if bias exists.

In September 2006, the PEP program was modified as follows:

•Primary Quality Assurance Organizations (PQAOs) with five or less PM2 5 monitoring sites are required to have five valid
audits per year distributed across four quarters; PQAOs with more than five PM2 5 monitoring sites are required to have eight
valid audits per year distributed across four quarters.

•100% completeness is required (meaning doing as  many audits as necessary in order to obtain either five or eight valid
samples).

•All samplers are  subject to an audit within six years.

 If a PM2 5 PEP audit isn't successfully completed (either because of problems with the states' or contractor's equipment, or
other obstacles), make up audits are performed as soon as possible - usually within the same quarter. This allows for better data
completeness. In addition, the EPA contractors in Region I also conduct semi-annual collocation studies using all five EPA
portable PM2 5 samplers. The samplers are collocated for three 24-hour sampling periods at EPA's North Chelmsford, MA
facility.

The 2007 PM2 5 PEP graph shows that in general, all six states performed very well during the year.
