1991 ANNUAL REPORT ON AIR QUALITY
IN NEW ENGLAND
This report represents 1991 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 4
CFR 58 . The only data from industrial monitors which have been included are from
the Massachusetts Industrial Network, EPA-required networks in New Hampshire
and from Maine’s licensing program which supplements the state network.
This report is intended to list potential nonattainment areas for planning
purposes. The majority of data used have been evaluated and verified by EPA;
however, for the areas listed as nonattainment, the data may require further
evaluation by both EPA and the states. This report reflects the status of the AIRS
database in April, 1992.
Table 1 is a summary of the status of the National Air Monitoring Sites
(NAMS) and the State/Local Air Monitoring Sites (SLAMS) submitting data to
Region I. This table lists the number of sites operating, the required number of
sites, the number of sites reporting precision and accuracy data, and the number of
sites not meeting EPA minimum data capture requirements. Following Table 1 is
a list of health effects of the criteria pollutants.
Table 2 shows the number of stations violating the National Ambient Air
Quality Standards (NAAQS) and the total number of stations reporting data during
1991.
Table 3 lists, by state, a summary of criteria pollutant data from sites in each
state in New England, and industrial sites from New Hampshire, Massachusetts, and
Maine. The information presented compares the measured values to each NAAQS.
The information included is the number of exceedences, the maximum and second
high values, and the annual means (arithmetic mean or average for SO 2 , PM 10 and
NO 2 ). For intermittent data, an annual mean is not valid unless there are four valid
quarters. For PM 10 , 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.
This table includes charts of selected air quality monitoring sites which show
a five year span of data for PM 10 , Pb, CO, SO 2 , and NO 2 . For ozone, a chart of the
number of days exceeding the standard each year for the last five years is used.
Also included is a discussion of the compliance status for each pollutant. In addition,
state maps are included which display pollutant levels and location of monitoring
sites.

-------
Table 4 shows the number of stations violating the NAAQS by Air Quality
Control Region (AQCR), as well as the total number of monitors in each AQCR.
A map delineating the AQCRs in Region I is included at the end of this table.
Table 5 has been developed to point out areas where air quality levels have
exceeded the emergency, warning, or alert episode levels. An air pollution alert,
warning or emergency will be called when specified pollutant concentrations are
reached, provided that meteorological conditions are such that these levels can be
expected to persist for 12 hours or more. In the case of ozone, an alert, warning or
emergency will be called if the situation is likely to recur within the next 24 hours.
Tables 6 and 7 list the precision and accuracy data submitted by the six New
England states. The 95% probability limits for six criteria pollutants are given as
a network average for each state.
Figure 8 lists the results from the Region I audit program for 03, SO 2 and
Particulates. The results presented on a state-by-state basis give the number of
satisfactory, marginal, and unsatisfactory audits.
Table 9 and 10, respectively, list the nonattainment areas in New England
with the last reported violation and the attainment and unclassified areas in which
there were recent violations of the NAAQS.
Appendix A is a list of AIRS state and regional Air Quality Contacts, their
addresses and phone numbers.

Health Effects of Criteria POllutanLs
Lead (Pb)
Carbon Monoxide (CO)
Lead causes retardation and brain damage, especially
in children. Lead also causes liver disease, interferes
with blood formation, the nervous system and the
renal system and can affect the normal functions of
the reproduction and cardiovascular systems. The
sources of lead pollution are motor-vehicle exhaust,
lead smelters and battery manufacturing plants.
Ozone (03)
Respiratory tract problems such as difficult breathing
and reduced lung function may be caused by high
ozone levels. Ozone also causes asthma, eve
irritation, nasal congestion, reduced resistance to
infection and premature aging of lung tissue. 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.
Nitrogen Oxides (N0 )
The health effects of this pollutant include respiratory
illness, lung damage,and increased airway resistance.
It may make one more susceptible to respiratory
infection. Nitrogen oxides can cause edema (in
concentrations of l0ppm for 8 hours); concentrations
of 20-30 ppm for 8 hours can produce fatal lung
damage. NO also reacts with hydrocarbons to form
photochemical oxidants. The sources of nitrogen
oxides are: Motor-vehicle exhaust, heat and power
generation, nitric acid, explosives, fertilizer plants,
and combustion of fuels.
Carbon Monoxide acts in the bloodstream to deprive
the heart and brain of oxygen. It impairs ability of
the blood to carry oxygen, and affects the
cardiovascular, nervous, and pulmonary system.
Moderate concentrations significantly reduce brain
functions, and can cause angina. Carbon Monoxide
is caused by the incomplete combustion of carbon,
which occurs in motor-vehicles, and some industrial
processes.
Sulfur Dioxide (SO,)
This pollutant causes respiratory tract problems, eve
irritation, and permanent harm to lung tisSue. It
combines with water to firm acid aerosols and
sulfuric acid mist which falls to earth as acid rain,
causing plant and structural damage, and acidifying
bodies of water. Sources of sulfur dioxide include
heat and power generation facilities, combustion
processes that use oil or coal containing sulfur.
sulfuric acid plants, petroleum refineries and smelters
of sulfur-containing ore.
Suspended Particulate Matter (PM 0 )
This pollutant causes eye and throat irritation.
bronchitis, lung damage, and impaired visibility. It
soils materials, causes corrosion, and acts as a carrier
of toxics adsorbed or absorbed in it. Motor vehicle
exhaust, industrial processes, incinerators, heat and
power generation, steel mills, smelters, demolition,
wood burning stoves, fugitive dust, and plants are
sources of suspended particulate matter.

There were no exceedances or violations of the 1-hour NAAQS at any of the five Carbon Monoxide (CO)
nonitoring sites in the state. The Morgan Street site was the only site which had one exceedance of the 8-hour
^AAQS. In 1990, the site was shutdown for part of the year because of construction and it reported values just
jnder the 8-hour standard. The Morgan Street site had one exceedance of the 8-hour NAAQS in 1989 and three
stceedances of the 8-hour NAAQS in 1988. The five year trend graph shows that the Bridgeport, Stamford, and
Vew Haven sites are well below the standard and are relatively stable. The graph also shows a slight decrease of
:O in Hartford.

Thirteen sites monitored for Sulfur Dioxide (SO2) in 1991. There were no exceedances or violations of the
nual, 24-hour or 3-hour NAAQS. Four sites shutdown (Milford, New Britain, Stamford, and Waterbury) and a
w site was established in Mansfield. The maximum SO2 annual average occurred at the State Street site in New
iven at 41% of the standard (a 4% decrease from last year) while the minimum SO2 annual average of 14% of the
tndard was reported in Mansfield. The highest second maximum daily SO2 levels were reported in New Haven at
% of the NAAQS, East Haven at 33% of the NAAQS and Bridgeport at 32% of the NAAQS. These three sites
o reported the highest second maximum 3-hour SO2 levels at 30%, 17%, and 18% of the NAAQS, respectively.
e SO2 five year trend graphs do not show any apparent trends for the monitoring locations chosen.

All eleven Ozone (O3) sites in the state have exceedances or violations of the NAAQS. The maximum value
monitored at any site in Connecticut was 0.193 ppm or 154% of the standard and was reported in Madison. The
highest second maximum of 0.175 ppm or 140% of the standard was also reported in Madison. An ozone site was
established in Torrington this year which reported a second maximum value of 0.126 ppm or 101% of the NAAQS.
In general, O3 levels were about the same as last year. The five year trend graph reveals that the greatest number of
exceedances/violations were reported in 1988.

Since New Haven is classified as a nonattainment area for Participate Matter less than 10
Microns (PM,0), daily monitoring is required. An exceedance occurred at the site located at the
corner of Stiles and Alabama Streets in New Haven. A first maximum value of 186 ug/m3 or
124% of the NAAQS was reported, and a second maximum value of 152 ug/m3 or 101% of the
NAAQS was reported. The annual arithmetic mean at this site was 47 ug/m3 or 94% of the
standard. The Stiles Street site in New Haven reported a first maximum value of 118 ug/m3 or
79% of the NAAQS and a second maximum value of 112 ug/m3 or 75% of the standard, as well
as an annual arithmetic mean of 40 ug/m3 or 80% of the standard. The Stiles Street site and the
site at the corner of Stiles and Alabama Streets continue to have the highest second maximum
daily and annual arithmetic means. An exceedance also occurred at the Darien site. A value of
171 ug/m3 or 114% of the NAAQS. This has been classified as an exceptional event due to
sandblasting near the monitor location. The five year weighted arithmetic mean trend graph
shows a decrease in the PM10 weighted arithmetic mean. There are no apparent trends for the
second maximum 24-hour value trend graph.

There were no violations of the quarterly Lead (Pb) NAAQS at any of the eight sites in Connecticut. The
site with the highest values in the state was the Waterbury Shed site which has a maximum quarterly average of 46%
of the NAAQS. This can be attributed to the sandblasting effect of bridge paint on 1-84. Two special purpose
monitoring sites which were installed in Waterbury to monitor the sandblasting effect of bridge paint were
discontinued this year when the bridge project was completed. Maximum quarterly Pb levels ranged from 1% - 10%
of the NAAQS. The quarterly averages for 1991 were generally lower than those for 1990 and for the most part
continue the five year downward trend.

The Carbon Monoxide (CO) background site at Bald Mountain which was established in 1990 shutdown in the
beginning of 1991. There were no exceedances or violations of the 1-hour or 8-hour NAAQS. CO values at this site were
3% of the 1-hour standard and 11% of the 8-hour standard. The five year trend graph shows a decreasing trend in CO
concentration for the Portland site which shutdown in 1989 due to a loss of lease on the site.

? INDICATES THAT THE MEAN DOES NOT SATISFY SUMMARY CRITERIA
There were no exceedances or violations reported at any of the seventeen Sulfur Dioxide (SOj) sites in 1991. The
highest annual arithmetic mean was reported in Madawaska at 26 ug/m3 or 33% of the standard. Madawaska also
reported the highest 24-hour second maximum of 126 ug/m3 or 35% of the standard as well as the highest 3-hour second
maximum of 300 ug/m3 or 23% of the standard. Acadia National Park reported the lowest 24-hour second maximum
of 17 ug/m3 or 5% of the standard as well as the lowest 3-hour second maximum of 45 ug/m3 or 3% of the standard.
The SOj five year trend graphs do not show any apparent trends for the monitoring locations chosen, except for
Rumford. The annual arithmetic mean graph for SO2 shows a decrease for Rumford.

Eight of the twelve Ozone (O3) sites operating in Maine had exceedances or violations of the O3 NAAQS in 1991.
The site which had the most exceedances in the state was Isle au Haut which had five. The Ocean Ave. site in
Kennebunkport had the highest second maximum value of 0.148 ug/m3 or 118% of the standard. In 1991, special study
sites were established at Augusta and Appledore Island. An O3 monitoring site was also established at the Pray Street
School in Gardiner during 1991. This replaced the Gardiner High School site. The five year trend graph reveals that
the greatest number of exceedances/violations occurred in 1988.

None of the thirty-nine Particulate Matter less than 10 Microns (PM10) sites in Maine had
exce«dances or violations of the annual or 24-hour NAAQS for PM10 in 1991. As in the past, the
highest values were reported at the Northeastland Hotel in Presque Isle. It reported the highest
second maximum value of 120 ug/m3 or 80% of the daily standard. All other sites were well below
the NAAQS. Two TSP monitors located in Brewer and Old Town were converted to PMi0 monitors
this year. PM10 sites were established at Rines Hill Parking Lot in Augusta and at the Municipal
Parking Lot in Waterville this year. The five year trend graphs show no discernable trends for
PM,n.

As in past years, Ozone (Oj) standard exceedances were reported at multiple sites in Massachusetts for 1991.
Thirteen out of sixteen sites exceeded the standard for 1991. The maximum O3 level measured in Massachusetts for 1991
was 0.165 ppm, recorded at the Turo site. The Turo site also recorded the most days over the standard in 1991, with
7 days in excess of the NAAQS. Second to the Turo site is the Quabbin Reservoir site in Ware with five days over the
standard. Its maximum O3 level was recorded at 0.151 ppm. The trend graph for O3 sites in Massachusetts shows that,
except for 1988, the number of days over the standard at each site has stayed relatively constant and varies between 0
days and 4 days over the standard for the sites selected. In 1988, summer temperatures were extremely and unusually
hot, promoting O3 formation and increasing the number of days over the standard at each site. Each of the trend sites
increased exceedances in 1988 and varied between 2 and 13 days over the standard.

Ten sites were monitored for Nitrogen Dioxide (NO2) in Massachusetts for 1991. An industrial monitoring site
located on Thurston St. was shut down this year. The highest annual means for the state were observed at the Kenmore
Square and Breman St. sites in Boston, with levels at 70% and 64% of the NAAQS, respectively. The lowest NO2 levels
were observed at the Quabbin reservoir in Ware at 18% of the NAAQS. The five year trend graph for NO2 shows a
decreasing trend for Kenmore Square, Worcester and Thurston St., Boston and an increasing trend for Chelsea. While
stable values are indicated for Ware and Breman St., Boston.

No exceedances of the NAAQS were recorded at any of the thirty-two monitoring sites which
reported Sulfur Dioxide (SO2) data for 1991 in Massachusetts. In 1991, there was one site
relocation. This was the Watertown SO2 site which was moved to Waltham. Maximum SO2 levels
for Massachusetts on an annual basis were reported in Boston at the Atlantic Ave. site at 40% of
the annual NAAQS. The site reporting the lowest annual mean was the Quabbin Reservoir site in
Ware at 16% of NAAQS. The site reporting the highest daily 24-hour SO2 values was an industrial
source oriented site in Lynn with a level of 49% of the NAAQS. The five year trend graph of SO2
arithmetic means for typical sites in Massachusetts shows a slight decreasing trend for Fall River
while the SO2 levels in Ware, Worcester, Lawrence, Boston and Springfield have remained relatively
constant. The trend graph for the 24-hour second maxima show similar but noisier trends with
Springfield, and Fall River exhibiting decreasing trends while levels in Lawrence, Worcester, Ware
and Boston have remained relatively constant.

As in past years, Ozone (O3) standard exceedances were reported at multiple sites in Massachusetts for 1991.
Thirteen out of sixteen sites exceeded the standard for 1991. The maximum O3 level measured in Massachusetts for 1991
was 0.165 ppm, recorded at the Turo site. The Turo site also recorded the most days over the standard in 1991, with
7 days in excess of the NAAQS. Second to the Turo site is the Quabbin Reservoir site in Ware with five days over the
standard. Its maximum O3 level was recorded at 0.151 ppm. The trend graph for O3 sites in Massachusetts shows that,
except for 1988, the number of days over the standard at each site has stayed relatively constant and varies between 0
days and 4 days over the standard for the sites selected. In 1988, summer temperatures were extremely and unusually
hot, promoting O3 formation and increasing the number of days over the standard at each site. Each of the trend sites
increased exceedances in 1988 and varied between 2 and 13 days over the standard.

Routine monitoring for Lead (Pb) began in 1982 with sites established in Boston, Lowell, Springfield and
Worcester. The present network consists of four sites two in Boston and two in Springfield, the two largest urban areas
in the state. Since 1982 lead levels have dropped continuously with the most rapid decline within recent years. This
trend is mainly due to a decrease in the use of leaded gasoline. The highest maximum quarterly average occured at two
sites, East Columbus Ave in Springfield and Kenmore Square in Boston. The highest maximum quarterly average was
less than 3% of the NAAQS.

In 1991 no exceedences of the NAAQS were recorded at either of the two Carbon Monoxide (CO) monitoring
sites in New Hampshire. The highest level recorded at the Nashua site was 8.9 ppm or 99% of the standard The
Manchester site recorded a maximum 8-hour concentration of 6.5 ppm or 72% of the standard Nather locat.on
exceeded the 1-hour standard of 35 ppm. The maximums for the 1-hour time period were 12.5 ppm for Manchester and
20.8 ppm for Nashua. The five year trend graph for CO did not reveal any apparent trend for Nashua white an
apparent upward trend for the relatively new Manchester site was evident. In Manchester, the monitoring locat.on was
changed from Elm St. to Manchester St. midway through 1989.

Sulfur Dioxide (SOZ) standards were not exceeded at any of the twelve monitoring sites located in New
Hampshire. For the second year in a row, the Pembroke monitoring site recorded the highest concentrations for all three
averaging times of interest, with levels of 157 ug/m3 (43% of 24-hour NAAQS), 517 ug/m3 (40% of 3-hour NAAQS) and
23 ug/m3 (29% of Annual NAAQS) in 1991. The SO2 five year trend graphs do not show any apparent trends for the
monitoring locations chosen.

Three of New Hampshire's seven Ozone (O3) sites exceeded the standard in 1991. These three include the Rye
Harbor, Portsmouth and Nashua sites. The Rye Harbor monitor recorded the highest 1-hour value at 135% of the
standard, the Portsmouth monitor recorded a 1-hour value at 115% of the standard and the Nashua monitor recorded
a 1-hour sample at 108% of the standard. Maximums at other sites ranged from 81% to 96% of the standard. The O3
five year trend graph illustrates the number of days per year that New Hampshire monitoring sites exceeded the
standard. For the Manchester site, exceedences were only measured in 1988, while the Rye Harbor site has seen
exceedences for the last five years. O3 levels throughout the region were higher and more frequent in 1988 due in part
to the unusually high summer temperatures for that year.

New Hampshire has increased its Paniculate Matter less than 10 Microns (PMW) Network
from eight sites in 1989 to sixteen sites in 1991. Of the sixteen sites, none exceeded the annual or
twenty four hour NAAQS for 1991. As in past years, the highest New Hampshire PM!0 values were
recorded in the Berlin Area. The Lancaster St. site in Berlin recorded the highest second maximum
24-hour value in the state at 106 ug/m3 (71% of the NAAQS) and an annual arithmetic mean of 40
ug/m3 (80% fo the NAAQS). Other locations in the Berlin area recorded second maximum 24-hour
concentrations ranging from 30% to 36% of the standard and annual means from 34% to 54% of
the standard. The monitor in Nashua recorded the next highest PM10 concentrations in New
Hampshire with levels at 41% of the 24-hour and 42% of the annual NAAQS. The lowest PMIO
levels in the state were measured at a site on top of Mt. Sunapee with PMJO levels averaging 11
ug/m3 or 22% of the the annual standard. The five year trend graphs for both the 24-hour and
annual mean values show slight increasing trends for Berlin and slight decreasing trends for
Manchester and Portsmouth.

None of the six Lead (Pb) sites in New Hampshire exceeded the standard for 1991. In fact, the highest quarterly
mean measured in the state was 0.02 ug/m3 (or less than 2% of the standard) at the Concord, Keene, Manchester and
Portsmouth sites. The two other sites in Hollis and Nashua had a maximum quarterly mean of 0.01 ug/m3 (the minimum
detection limit). Pb levels have dropped off considerably since 1982 when routine Pb monitoring was initiated in New
Hampshire. This is due in part to the use of unleaded instead of leaded gasoline. The maximum quarterly mean for
1982 was 0.47 ug/m3 or 31% of the standard. The five year trend graph for maximum Pb quarterly means shows that
lead levels have dropped in Concord, Nashua and Hollis, with Concord levels reduced by 45% since 1987.

1991 Air Quality DATA SUBMITTAL S
Explanatory Notes:
The Purpose of this Report:
The purpose of this report Is to compare the NAMS air quality data that are in
AIRS/AQS with what should be there, and to report the results for each state.
Explanation of Key:
KEY: D D d NOT R.qjb.msnt ‘ Mst A 4rsmsnt No R.g nh
This means that AMP43O shows that Ihe numbers of monitors meeting summary
crltena is less than the number of monitors for that quarter, for that
pollutant, for that state. The number inside the box indicates the percentage
of monitors meeting, the data completeness cnteria.
For PM1O the data for a monitor must meet 2 requIrements to meet summery
crIteria: (1) the data capture must be 75% based on the sampling frequency
reported with the data and (2) the sampling frequency reported with the data
must be at least as frequent as the required sampling frequency based on
40 CFR Part 58.
D This means that the two numbers referred to above are equal.
0 This means that the numbers of monitorsu referred to above is ZERO. There
may, in reality, be a reporting requirement but as yet no approved NAMS
monitor; this report would categonze that situation as Nno reporting
requirement.

Region I 1991 Performance Audit Program
Region I conducts an audit program to assess the performance
of Ambient Air Monitoring Networks and provides operators of these
Networks with technical assistance to maintain and improve overall
data quality. The procedures used in Volume II, of the U.S. EPA
Quality Assurance Handbook for Air Pollution Measurements. Gaseous
pollutant audits are conducted by introducing a known concentration
of a specific pollutant (traceable to the National Institute of
Standards and Technology, NIST) into the monitor’s sample intake,
recording the response of the audited instrument, and comparing the
instrument’s response to the actual or known concentration. Mass
Flow and Volumetric Flow controlled instruments for Particulate
Matter less than 10 microns in size (PM 10 ) are audited by attaching
a reference flow device to the monitor restricting air flow to a
known rate. The known air flow rate is then compared with the rate
of flow indicated by the sampler. These on site performance audits
are conducted by EPA Region I Ambient ir and Emissions Monitoring
Section in Lexington.
A total of 113 audits were conducted in the six New England
States on instruments that measure Ozone (03), Sulfur Dioxide (SO 2 ),
and Particulate Matter less than 10 microns in size (PM 10 ).
Of the 48 03 audits conducted in 1991, 97% passed, 0% were
Marginal, and 3% failed. The Acadia National Park, Acadia, ME site
recorded widely unstable concentrations during the audit, and
therefore, failed. Approximately one month later a re-audit was
conducted that showed that the problem had been corrected and the
site passed the second audit. The Brown University, Providence, RI
site recorded readings which averaged 20% low during the audit, and
therefore, failed. The State of Rhode Island later discovered that
the internal instrument scrubber was exhausted and was replaced.
EPA then conducted a re-audit and the site passed. Region I’s 03
audits continue to focus on coastal 03 sites due to the concern that
03 may be transported up the coast and peak 03 levels are usually
experienced at these sites.
All of the 19 SO 2 audits which were conducted in 1991 passed.
The number of SO 2 audits have been decreased due to excellent
performance in past years of state monitoring networks. For this
pollutant several representative audits were conducted for each
state network.
Forty-six PM 10 audits were conducted with only one failure in
1991. The only problems encountered with PM 10 in 1991 were related
to the 1991 PM 10 filter shipment. Inconsistent flows were
encountered from filters in the same lot which caused the states to
adjust their existing PM 10 monitoring procedures to compensate for
this problem.
