1985 ANNUAL REPORT ON AIR QUALITY
IN NE J ENGLAND
This report represents 1985 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 EPA—required networks in New Hampshire
and from Maine’s licensing program which supplements the state’s network.
This report is intended to list potential nonattaininent areas for
planning purposes. The majority of data used has 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.
Table I is a summary of the status of the National Air Monitoring
Sites (NANS) 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.
Table 2 shows the number of stations violating the National Ambient
Air Quality Standards (NAAQS) and the total number of stations reporting
data during 1985. There were no stations in violation of the SO 2 standards.
For particulates, no stations were in violation of the 24 hour primary
standard, and eleven stations were in violation of the 24 hour secondary
standard. The annual primary standard was violated at two stations. Five
stations were in violation of the CO 8—hour primary standard, and no
stations were in violation of the 1—hour primary standard. For ozone,
there were twenty five stations in violation of the 1—hour primary
standard. No stations violated the NO 2 annual standard or the lead
quarterly standard.
Table 3 lists every state site in New England. 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 (geometric mean for TSP, arithmetic mean or average
for SO 2 and NO 2 ). Those stations reporting a maximum above the standard,
but a second high below the standard are included in this table. For

-------
intermittent data, an annual mean is not valid unless there are four
valid quarters. To be considered valid, a quarter must have at least
five values; and if any one month is missing, each of the other two months
must have two or more values. For continuous data, 75 percent of the
year must be available to calculate a valid annual average.
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 1 is included at the
end of this table (Figure 1).
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 condi-
tions 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 reoccur within the next 24 hours.
Episode levels were reached or exceeded for ozone at two sites.
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.
Table 8 lists the results from the Region I audit program for TSP,
SO 2 , CO, NO 2 , and 03. The results presented on a state—by—state basis
give the number of satisfactory, marginal, and unsatisfactory audits.
Tables 9 and 10, respectively, list the nonattainment areas in New
England with the last reported violation and the attainment and unclass-
ified areas in which there were recent violations to NAAQS.
Following Table 10 is a discussion of air quality trends in New
England for the criteria pollutants. This discussion includes several
charts of selected air quality montoring sites which show a linear regres-
sion of the deseasonalized monthly means for TSP, Pb, CO. SO 2 , and NO 2
during the last five years. For ozone, a chart of the number of days
exceeding the standard each year for the last five years is used.

1985 PRECISION AND ACCURACY DATA
Current Federal Regulations require that each State report both
precision and accuracy data for all data from National Air Monitoring
sites (NAMS), and State/Local Monitoring Sites (SLAMS). Tables 6 and 7
list the precision and accuracy data submitted by the six New England
States. The data listed in these tables are the upper and lower 95%
probability limits in percent difference from a known standard reported
as a network average. The accuracy data in Table 7 are only for the
lowest reported concentration range. For TSP, the accuracy limits apply
only to the flow measurement, and the precision limits are the 95%
confidence limits between co—located monitors.
From these tables, CO has the lowest probability limits generally
within + 10%. All the other pollutants reported are, in general, within
approximately + 15%. Although no acceptance criteria have been set by
EPA to date, Region I expects this type of performance to be satisfactory.
For comparison, the 1985 National Statistics are also included in Tables
6A and 7A.
Generally, precision and accuracy data improved over that reported
in 1984. Particular improvement was noted in Connecticut’s precision
data for all pollutants and accuracy data for 0, SO 2 , and NO 2 . Also
notable was improved TSP and Pb accuracy data for Massachusetts, TSP and
ozone accuracy data for New Hampshire, and ozone accuracy data for Vermont.
TSP precision data and Pb accuracy data for New Hampshire, however, were
worse as was Pb precision data for Rhode Island. All other precision and
accuracy data for Region I remained relatively unchanged. By contrast,
the National average accuracy data was noticably worse with precision
improving significantly only for SO 2 .

REGION 1 1985 PERFORMANCE AUDIT PROGRAM
Region I conducts an audit program to determine the performance of
ambient air monitoring systems and to provide their operators with technical
assistance in improving data quality. Continuous air monitors are audited
by allowing them to sample gas inixtrures containing known concentrations of
specific pollutants and noting the analyzers’ responses. High—volume air
samplers for TSP, lead, and inhalable particulates (PM—b) are audited by
attaching a flow reference device and comparing a known air flow rate with
the rate recorded or indicated by the sampler.
A total of 188 audits were conducted in the six New England states for
particulates (TSP, lead, and PM—1O), SO 2 , CO, NO 2 and ozone by personnel from
Region I. In general, the results were very good with 175 audits (93%)
satisfactory, 7 audits (4%) marginal, and only 6 audits (3%) unsatisfactory.
These results are similar to those achieved in 1984.
Particulate sampler audit results were relatively unchanged from 1984,
during which 7% of the audits were marginal. In 1985, only 4% were marginal,
but 2% were unsatisfactory. All of the states in Region I have adopted
revised procedures consistent with the current TSP Reference Method promul-
gated by EPA, which should yield better results once site operators and
laboratory personnel become familiar with the changed procedures.
Performance on individual NO 2 audits improved in 1985. There was,
however, one audit in Massachusetts In which the instrument did not meet
satisfactory criteria. Recent replacement of older NO 2 instruments should
result in improved results.
Ozone audits were generally good with the exception of one marginal
audit in Massachusetts.
SO 2 audit results were generally satisfactory with the exception of a
single failure each in Connecticut, Rhode Island and Vermont. Region I
provided the states with assistance in diagnosing the possible causes of
the failures. Most of the failed analyzers were older units in which
critical components malfunctioned. These results Indicate the need for
replacement or repair of older analyzers in those states affected.
Results for CO were generally good in all states audited.
Table 8 summarIzes the results of the audit program on a state—by—state
basis.

selected trends for each of the New England States. The data for these
analyses were collected by the New England States and were submitted to
EPA in fulfillment of the Federal monitoring requirements.
In evaluating the five—year urban air quality trends throughout New
England, a statistical program package developed by Region 5 was used to
help characterize the trends for TSP,Pb, CO, NO 2 and SO 2 sites. Due to an
insufficient data base, these programs were not employed for 03 sites.
This statistical program segments the data at each site into monthly cells,
produces monthly means, deseasonalizes these monthly means by aligning the
data for various years (in this case, five years 1981—1985) for each common
month, performs a linear regression on these deseasonalized monthly means,
and finally computes two test statistics which indicate the relative sig-
nificance of any trends identified. To be consistent with the appropriate
National Ambient Air Quality Standards (NAAQS), geometric means are used
for TSP, while arithmetic means are used for the other pollutants. TSP, Pb,
O, SO 2 , and NO 2 trend lines for selected air monitoring sites are presented
in Figures 2 through 6.
A different approach was used to present ozone trends. Ozone viola-
tions only occur during the late spring and summer months in New England.
Monitoring is conducted from April through October only; consequently, the
deseasona].ized linear regression lines would be of little value. Figure 7
shows a plot of the number of days over the standard for selected sites in
Middletown, Connecticut; Cape Elizabeth, Maine; Medfield, Massachusetts;
Manchester, New Hampshire; and Kent County, Rhode Island. The sites
selected for this figure show both increasing and decreasing trends. When
using the ozone trend lines, please remember that meteorology plays a very
important and complex role in the formation of ozone. Given the yearly
variation in meteorology, it is possible that the apparent fluctuations in
ozone levels are a result of normal variations due to meteorology rather than
actual reductions In emissions.

1985 CONNECTICUT AMBIENT AIR QUALITY SUMMARY
TSP
There were three exceedences of the daily secondary standard during
1985. These occurred at sites in Norwich, Stamford and New Haven. This
is in comparison to no TSP exceedences in both 1984 and 1983. The
highest annual geometric mean was measured in Bridgeport at 66 ug/m 3 or
88% of the annual primary NAAQS. Annual geometric means were 80% of the
standard in Hartford, 76% in Stamford and 68% in Waterbury. The maximum
second highest daily average was measured in Stamford and was 55% of the
primary daily NAAQS. The second highest daily averages in the larger
urban areas ranged from 26% to 55% of the primary daily NAAQS. Rural
background levels were 28% of the annual primary standard and 41% of the
secondary daily standard. In general, urban TSP levels were greater than
those reported in 1984 and 1983.
Five year trend lines were prepared for thirty six TSP sites in
Connecticut. Five sites had increasing trends of at least a 90%
confidence level. Thirty one sites did not show significant trends,
although the majority of these sites had a definite positive slope. The
trend lines for both Bridgeport and Hartford are shown in Figure 2.
Pb
There were no violations to the NAAQS reported in 1985. The highest
quarterly average was measured in Hartford at 39% of the NAAQS. Waterbury
had the second highest quarterly average at 32% of the standard. Maximum
quarterly averages in other urban areas ranged from 6.0% to 32% of the
standard. In general, lead levels are lower than those reported in 1984
and 1983.
Co
There were no exceedences or violations of the 1 hour NAAQS reported
in 1985. Bridgeport, Hartford and Stamford reported exceedences of the 8
hour NAAQS. In total, seven CO 8 hour exceedences were reported in 1985
as compared to the fifteen exceedences reported in 1984. In general,
Connecticut’s 1985 CO levels were slightly lower than those reported in
1984.
77

-------
A five year trend analysis was prepared for four Co sites. These
sites all showed significant downward trends. The Stamford CO site is
included in Figure 4.
22
No violations or exceedences to the NAAQS were reported in 1985. The
maximum SO 2 annual averages occurred in Bridgeport at 45% of the standard,
and in New Haven at 45% and 55%. The highest daily SO 2 levels were
u asured in New Haven at 68% of the daily standard. The second highest
daily average also occurred in New Haven at 50% of the NAAQS.
In general, 1985 SO 2 annual averages were the same as those in 1984
and 1983. The five year trends for eight sites were analyzed. The Danbury
trailer, Milford Community Center and Hartford trailer sites showed
significant downward trends while the New Haven trailer site showed a
significant u ard swing. The Hartford trailer SO 2 trend line is
included in Figure 5.
The NO 2 sites in Bridgeport, East Hartford and New Haven reported
values of 50%, 39% and 58% of the annual standard, respectively. These
values are generally the same as those reported in 1984. The five year
trend lines for these sites were analyzed. The New Haven trailer site
showed a significant increase in NO 2 concentration. The East Hartford
site showed a non—significant increase and the Bridgeport site displayed a
slight downward trend. These plots are displayed in Figure 6.
Every site in Connecticut reported between three to thirteen days
over the primary NAAQS. The maximum daily reading during 1985 was .219
ppm and occurred in Middletown. In general, ozone levels were slightly
lower in 1985 than the 1984 values. Figure 7 shows a plot of the number
of days over the standard for the Middletown site.

1985 MAINE AMBIENT AIR QUALITY SUMMARY
TSP
A Primary National Ambient Air Quality Standards (NAAQS) exceedence
was measured in Presque Isle. No primary standards violations were
recorded. Secondary standards violations were reported in Bangor,
Lincoln, Oxford County, Presque Isle, Washington County, and Westbrook.
An exceedence was reported in Augusta, Madawaska, Mexico, Millinocket,
Old Town, Bangor and Portland. There were no violations of the annual
standard. The annual geometric mean was 95% of the NAAQS in Westbrook,
80% in Bangor, 79% in Presque Isle, 75% in South Paris, and 68% in
Mexico. The TSP site with the best air quality was Acadia National Park
which reported levels 16% of the annual NAAQS.
The five year trend analysis was performed on thirty nine TSP sites
in Maine. Of these thirty nine sites, six showed significant increasing
trends. Sixteen sites showed no significant trends, and the remaining
seventeen sites showed a significant downward trend. Although the
majority of the regression lines show a downward trend, the number of lines
with no significant and increasing trends indicate that particulate
values may be leveling off after continuous decreases over the past
years. Several sites showed lower values than those reported last year.
These sites include: Jay, Augusta, Madawaska and Presque Isle. Primary
standards violations were eliminated in Augusta and Washington County
since last year. Figure 2 shows a decreasing five year trend line for
Lincoln and an increasing line for Bangor.
Lead
There were no violations of the quarterly lead NAAQS. The highest
statewide concentration was measured in Portland (microscale site) and
was 58% of the standard. Quarterly means were only 21% of the standard.
Last year’s maximum level was 73% of the NAAQS at the Portland site.
However, this site was shut down during 1985 because of road construction.
Maximum levels measured in Bangor and Presque Isle were approximately 41%
of the standard. Lead levels generally followed a decreasing trend
throughout the State. Figure 3 shows a decreasing trend line for the
Portland Tukey’s Bridge site.
79

-------
Co
The only CO monitoring site in the State is located In Portland.
The site was moved from Bangor in 1984. Reported CO levels in Portland
were higher than the levels measured in Bangor. The maximum 1 hour value
in Portland increased from 12.2 mg/rn 3 in 1984 to 15.6 mg/rn 3 in 1985. The
maximum 8 hour value also showed a slight increase.
The highest 1985 concentration was 39% of the 1 hour NAAQS, and for
the 8 hour NAAQS, the highest concentration was 85% of the standard.
Statewide CO levels appear to be approximately the same or slightly
increasing over the past several years. At present, there is insufficient
data in Portland to conduct a five year trend analysis.
The highest daily SO 2 levels were monitored in Waldo County at an
industrial site. The values were approximately 57% of the 24 hour standard
Monitored values in Millinocket were 48% of the standard, while Rumford
and Kittery showed values of approximately 42% of the daily standard.
Levels in Mexico, Madawaska and Portland were approximately 34% of the
standard. The highest 3 hour levels were monitored in Kittery at 69% of
the standard. Waldo County measured values 46% of the standard, and
levels in Millinocket were 35% of the standard. Although maximum SO 2
values in Maine are only 69% of the NAAQS, a review of the historical data
base shows less SO 2 reduction in current years.
The five year trend analysis was conducted for eighteen sites.
Eight sites showed decreasing trends, while ten showed no significant
trends. The trend line for Millinocket shows a 30% reduction over the
five year period. This resulted from the installation of control
equipment at a local paper mill. Levels in Madawaska show up to 45%
reduction as a result of reduced fuel burning activity at a local mill.
Figure 5 shows a reducing trend line for Madawaska.
22
Maine is not required to monitor NO 2 ; however, at present, one special
purpose NO 2 site is operating in Portland. This site is gathering
information for an ozone study and will be shut down once sufficient
information is obtained.
80

-------
Of the eight sites operated in Maine, four monitors measured NAAQS
violations. The Cape Elizabeth and York County sites measured four days
over the standard, Gardner measured three and the Lincoln County site
measured two days over the standard.
The Hancock County site measured one day over the standard while
Acadia National Park, Waldo and the Washington County site had no monitored
exceedences in 1985. The highest value recorded (.170 ppm) was measured
at the York County site. The site measuring the lowest values is located
in Washington County. This site measured a maximum value of .099 ppm or
79% of the NAAQS.
In general, ozone values and the number of days over the standard
decreased from 1984 results. However, while no violations were measured
at the Gardner and Lincoln County sites in 1984, both sites measured
violations in 1985. The frequency of violations at the York County site
decreased from eleven in 1984 to three in 1985. The Cape Elizabeth site
had six days over the standard in 1984 and four in 1985. Figure 7 shows
a plot of the number of days over the standard for the Cape Elizabeth
site.

1985 MASSACHUSETTS AMBIENT AIR QUALITY SUMMARY
TSP
The primary annual and the secondary 24 hour NAAQS were violated at only
one site in Massachusetts; the newly established City Square site in the
Charlestown section of Boston. One other site, the Lowell YMCA site, reported
an exceedence to the secondary 24 hour NAAQS. TSP sites with the highest
annual geometric means were located in Boston at 108% of the NAAQS, Holyoke
at 72% of the NAAQS, Lowell at 72% of the NAAQS, Springfield at 67% of the
NA.AQS, and Worcester at 71% of the NAAQS. The highest second maximum daily
TSP values were measured in Boston at 101% of the secondary NAAQS, in Chelsea
at 97% of the NAAQS, in Lowell at 100% of the NAAQS, and in Worcester at 93%
of the NAAQS. The lowest TSP levels were measured at a rural background site
in Warren with levels at 32% of the primary annual, 20% of the primary daily,
and 34% of the secondary daily standards.
A total of sixteen sites were analyzed for five year trends. The analysis
indicated that one site had a significant upward trend, nine sites had
significant downward trends and six sites had no significant trends. While
the majority of the sites indicated decreasing trends, the large percentage
of sites with no significant trends suggest that particulate levels are
leveling off in Massachusetts after several years of significant decreases.
Figure 2 shows decreasing trend lines for Boston and Springfield.
Lead
Routine monitoring for lead began in 1982 with sites established in
Boston, Chelsea, Lowell, Springfield and Worcester. No violations to the
quarterly lead NAAQS have been reported from the present network to date.
Maximum quarterly lead levels decreased from 1984 levels at all sites. The
highest site in the State was in Springfield with a maximum quarterly average
of 48% of the NAAQS. Maximum quarterly lead levels from other urban areas in
the state ranged from 15% to 29% of the NAAQS.
CO
No exceedences to the 1 hour or the 8 hour NAAQS were reported for
the eight sites which monitored CO in the State for 1985. This is a
significant improvement over 1984 levels where four out of the eight sites
82

-------
reported violations to the 8 hour NAAQS. Second high 8 hour averages
decreased at every site and ranged from —17% to —38% over 1984 levels.
A five year trend analysis was conducted for all eight SO 2
monitoring sites. Seven sites exhibited significant decreasing trends
while the Worcester site exhibited a nonsignificant increasing trend.
Figure 4 depicts the five year trend line for the microscale site
located at 600 Washington Street in Boston. Neighborhood (suburban) CO
levels were 23% and 58% of the the 1 hour and 8 hour NAAQS in Boston,
and 17% and 45% of the NAAQS in Springfield. The highest second
maximum 1 hour average for the State in 1985 was measured at the 600
Washington Street site in Boston and was 40% of the one hour NAAQS.
The highest second maximum 8 hour average for the State was measured at
two sites in 1985; the 600 Washington Street site in Boston and the Old
City Hall site in Lowell at 95% of its NAAQS.
There were no violations of the NAAQS at any of the seventeen
sites which reported SO 2 data for 1985 in Massachusetts. Maximum SO 2
levels for Massachusetts on an annual basis were reported in Boston at
two sites; Kenmore Square and Kneeland Street at 43% of the the annual
NAAQS. Minimum SO 2 levels on an annual basis were measured in Medfield
at 15% of the NAAQS. Highest second maximum daily SO 2 levels were
reported for Springfield at 39% of the NAAQS, Boston at 35% of the
NAAQS, Chelsea at 33% of the NAAQS and Fall River at 31% of the NAAQS.
A total of fifteen sites were analyzed for five year trends.
Significant downward trends were identified for eight sites located in
Chicopee, Lowell, Medfield, Springfield, Watertown and all three sites
in Boston. Significant upward trends were identified for Pittsfield and
Lawrence. The remaining five sites did not exhibit any significant
trends. The trend line for the Kenmore Square site is depicted in
Figure 5.
22
In 1985, six sites collected NO 2 data in Massachusetts. The
maximum site in the State was located in Kenmore Square, Boston, where
the annual mean was 75% of the NAAQS, a 10% decrease over 1984 levels.
At the other Boston site, the annual mean decreased by 7% over 1984
83

-------
levels. Increases in NO 2 levels were reported for Chelsea (+7%) and
Fall River (+14%) while slight decreases were reported for Lawrence
(—2%) and Springfield (—4%).
A five year trend analysis was performed on the four sites with
sufficient data records. A significant decreasing trend was identified
for the Lawrence site. No significant long term trends were identified
for the other three sites analyzed. Minimum NO 2 levels for the State
were reported for the Fall River site at 32% of the annual standard.
23
As in past years, ozone violations were reported throughout
Massachusetts for 1985. Violations were recorded at nine out of
fourteen sites which operated in 1985. Sites in Amherst, Chelsea,
Easton and Lawrence reported one daily exceedence of the standard for
the year while the site in Pittsfield did not report any daily values
over the standard.
Overall, maximum daily ozone levels decreased in 1985 as compared
with 1984. Six sites reported decreases in the top two maximum days
for the year and ranged from —5% to —29%. Maximum daily values for the
year did not change significantly at four sites. The remaining four
sites reported increases averaging 8% to 21% over 1984 maximums. The
total number of days in excess of the standard for the fourteen sites
which operated in both 1984 and 1985, decreased from forty seven days
in 1984 to thirty five days in 1985. Six sites recorded reductions in
the number of days over the standard while an equal number of sites
experienced increases.
The maximum daily value for 1985 in Massachusetts was recorded in
Chicopee at 0.198 ppm. The Chicopee site also recorded the most number
of days over the standard with six days for 1985. The Fairhaven site had
previously been the site with the most number of days over the standard
with seventeen days in 1983 and nine days in 1984. Fairhaven dropped
to only three days in 1985. Figure 7 shows a five year trend plot of
the number of days over the standard for the Medfield site which is
located in the southwestern sector of the Boston urban area.

-------
1985 NEW HAMPSHIRE AMBIENT AIR QUALITY SUMMARY
TSP
The only site in New Hampshire which reported violations to the primary
and secondary NAAQS in 1985 was the Berlin, Lancaster Street, trailer site.
Four values over the 24 hour secondary standard were recorded at this site
in 1985. This is an improvement over 1984 levels where the primary 24 hour
standard was exceeded three times and the secondary 24 hour standard was
exceeded eleven times. Although this site continued to show a violation to
the primary annual standard in 1985, the annual geometric mean dropped from
87 ug/m 3 in 1984 to 77 ug/m 3 in 1985. One other site, located on Dutil
Street in Berlin recorded one exceedence of the secondary daily standard.
The air quality in Berlin is influenced by manufacturing activity at a
local paper mill. All other TSP sites in the State are below standards.
The annual geometric means for other areas in New Hampshire were 41% of
the standard in Concord, 61% in Manchester, 61% in Nashua and 68% in
Portsmouth. Background levels in Hollis are 33% of the annual standard.
A five year trend analysis was performed on seventeen TSP sites in New
Hampshire. Of these seventeen sites, ten showed significant long term
downward trends, while the remaining seven sites showed no significant
trends. Last year, the long term trend analysis indicated that 80% of the
sites analyzed were significantly decreasing. In this year’s analysis less
than 60% of the sites were significantly decreasing. The indication is
that TSP levels may be leveling off in New Hampshire. Figure 2 shows a
significant decreasing trend line for the State House Annex site in
Concord.
Lead
There were no lead violations reported in 1985 at the nine sites which
monitor this pollutant in New Hampshire. The highest site — a microscale
site in Concord — reported a maximum quarterly average which was 24% of the
NAAQS. The lowest site in the State, which is located in Hollis, had a
maximum quarterly average of 5% of the standard. Lead levels have decreased
at all sites in 1985 as compared with 1984 levels.
85

-------
Co
No violations of the 1 hour NAAQS were reported in 1985; however,
both Nashua and Manchester reported violations to the 8 hour NAAQS. A
total of eleven violations were monitored in Manchester for 1985 as
compared to eight violations reported for 1984. The maximum 8 hour level
was 36% over the standard in 1985 compared to the 1984 maxImum which was
51% over the standard. For Manchester, the frequency of violations
increased in 1985 while the magnitude of the violations decreased
significantly. In Nashua, both the frequency and magnitude of viola-
tions decreased. The frequency of violations decreased from twenty one
violations in 1984 to only two in 1985, while the maximum 8 hour level went
from 81% to 22% over the standard.
The Nashua site was analyzed for long term trends. A significant
downward trend was identified for mean CO levels at this site.
No violations to the NAAQS were monitored in 1985. The last violation
measured in New Hampshire occured in 1980 at a site in Berlin. The highest
statewide levels recorded on an annual basis were monitored in Manchester
and Pembroke at 31% of the annual NAAQS for 1985. On a short term basis,
the highest SO 2 levels were monitored in Pembroke with levels at 54% of the
daily NAAQS and 37% of the 3 hour NAAQS.
In general, most areas In New Hampshire saw decreases in SO 2 from
levels measured in 1984. Two areas showed Increases in the past year,
Pembroke and Portsmouth. A five year trend analysis was performed for ten
sites. Eight sites were identified with significant decreasing trends,
while two sites located in Pembroke and Berlin had significant increasing
trends. Figure 5 shows a downward five year trend line for the Lancaster
Street site In Berlin.
22
No site in New Hampshire collected NO 2 data in 1985.
23
None of the five sites which operated in 1985 recorded violations of
the NAAQS, although one day exceedences were reported for Nashua and
Portsmouth. The highest daily maximum for the State in 1985 was monitored
86

-------
in Nashua and was 110% of the NAAQS. Generally, 1985 ozone levels were
similar to those recorded in 1984. Figure 7 shows the number of days over
the standard for the Manchester site.

-------
1985 RHODE ISLAND AMBIENT AIR QUALITY SUMMARY
TSP
There were no reported violations or exceedences of the primary and
secondary National Ambient Air Quality Standards (NAAQS) in 1985. The
highest geometric mean occurred at the Bonanza Bus Terminal site in
Providence. This is equivalent to 81% of the annual primary NAAQS. This
site also had the second highest daily average which was 49% of the
primary daily NAAQS. The highest daily average was measured in Providence
at the State Street parking lot site and was 92% of the secondary NAAQS.
The rural background site located at the University of Rhode Island’s
Alton Jones Campus was 27% of the primary annual NAAQS and 33% of the
daily secondary standard.
TSP levels throughout the State have shown a general decrease from
1982 to 1985. The rural Alton Jones site, at approximately 27% of the
primary annual standard, has shown an increase over 1984 at 25% and 1983 at
24%. The background TSP levels of 1986 are similar to those exhibited in
1982.
A five year trend analysis was performed at eleven TSP sites.
Fourth quarter 1985 data was not available at the time these trends were
run. Of these, the Cranston, Newport and East Providence Fire Station
sites showed significant downward trends, while eight sites exhibited no
significant trend. Figure 2 shows a typical five year trend line for a
site in Providence.
Pb
There were no calender quarter arithmetic means greater than the
primary and secondary NAAQS in 1985. As in 1984, the highest quarterly
lead average occurred at Dyer Street and was 35% of the NAAQS. The second
highest quarterly average also occurred at Dyer Street at 27% of the
standard. The maximum background level, as measured at the University of
Rhode Island’s Alton Jones campus in Kent County, was 4% of the standard
during the highest quarter. Pb levels have shown a decrease from 1982 to
1985.
A five year trend analysis was performed for five Pb sites in Rhode
Island. Of these, the Bonanza Bus, Westminster Street and Dyer Street
sites in Providence and the Cranston site showed significant downward
88

-------
trends, while one site had no significant tendency. Figure 3 shows the
five year Pb trend line for a typical site in Providence.
Co
There were no exceedences of the 1 hour NAAQS in 1985. However, the
microscale site at Dorrence Street in Providence reported two exceedences
of the 8 hour NAAQS, as compared to five exceedences in 1984 and three in
1983. At the neighborhood site (Rockefeller Library) the second highest
8 hour value decreased to 46% of the standard from 60% in 1984 and 77% in
1983.
Figure 4 shows a significant downward trend in the mean CO levels at
Dorrence Street site. The Rockefeller CO site displayed a significant
urward trend.
Q2
No violations of NAAQS were reported in Rhode Island over the past
five years. The highest levels in 1985 occurred in Providence and
Pawtucket at 38% of the 24 hour primary NAAQS. The second highest values
were reported in Pawtucket at 34% of the 24 hour standard.
A five year trend analysis was performed for four SO 2 sites in Rhode
Island. Of these, the Rockefeller Library and State Street sites in
Providence showed a significant downward trend, while the Dorrance Street
site showed a significant upward trend. Figure 5 displays a typical
trend line for the Providence area.
The one NO 2 site in Providence reported an annual average of 49% of
the standard. This is slightly higher than the 1984 value of 47% and the
1983 value of 45%. Figure 6 shows a trend analysis displaying a slight
uNard trend in Rhode Island’s NO 2 concentrations.
p-3
The Kent County site reported five days during which the 1 hour NAAQS
was exceeded, while the Providence site only reported two such days. The
highest daily value reported for Kent County was .154 ppm. This is lower
than the 1984 value of .215 ppm and is comparable to the concentrations
of .150 ppm and .158 ppm in 1983 and 1982, respectively. The Kent County
89

-------
site has had the greatest number of measured days over the NAAQS for the
past four years. The highest daily value in Providence was .132 ppm or
approximately 10% over the NAAQS. Figure 7 shows a plot of the number of
days over the Kent County site.

1985 VERMONT AMBIENT AIR QUALITY SUMMARY
TSP
In terms of the 24—hour National Air Quality Standards (NAAQS) just
one exceedence of the primary and secondary standards (260 ug/m 3 and 150
ug/m 3 , respectively) was observed in Vermont for 1985. This occurred at the
Burlington site where a value of 341 uglm 3 was recorded on May 31, 1985.
Since the next highest value at this site was 142 ug/m 3 , which is below the
secondary NAAQS, no violation occurred at this site. Maximum 24—hour TSP
levels for the rest of Vermont were below the NAAQS. The 1985 daily maximums
for each of these sites ranged from 140 ug/m 3 in Barre to 53 ug/m 3 in
Randolph.
Mean TSP levels were higher in Rutland and Barre than in Burlington.
Annual geometric means for Rutland and Barre were 69% and 67% of the
primary annual NAAQS while Burlington TSP levels averaged 59% of the
standard. Levels at the remaining sites were all less than 50% of the
standard with the lowest levels measured at the Randolph site at 29% of the
standard.
A five year trend analysis was performed on five sites in Vermont.
Three sites showed significant downward trends, while the two other sites
showed no significant but downward trends over the five year period.
Figure 2 shows the decreasing trend line for the Barre TSP site.
Lead
Vermont is not required to and does not operate a monitoring network
for lead.
CO
Carbon monoxide is monitored only in Burlington. Maximum levels at
this site were 21% of the one hour NAAQS and 64% of the 8 hour standard.
These levels were slightly higher than 1984 maximums. A five year trend
analysis was performed for this site and showed that mean CO levels increased
over the 1981 through 1985 time period. Although a significant u ard
trend was identified, the increase in terms of concentration was small,
averaging 0.07 mg/rn 3 per year.
91

-------
22
The Burlington site is the only site which monitors SO 2 year round
in Vermont. Levels at this site for 1985 were 16% of the daily NAAQS
and 20% of the annual NAAQS, a decrease over 1984 levels. Monitors in
Barre and Rutland operate from September through April each heating
season. Maximum levels at these two sites were 18% of the daily
standard in Barre and 22% of the daily standard in Rutland. Maximum
daily levels for both these sites decreased significantly over 1984
levels with a decrease of 38% in Barre and 49% in Rutland. The five
year trend line for Burlington is shown in Figure 5, and indicates a
nonsignificant trend with a slightly negative slope.
!22
Vermont initiated monitoring for NO 2 in Burlington during the
fourth quarter of 1985. This is Vermont’s first monitoring effort for
this pollutant. The arithmetic mean for three months of data is 31% of
the annual NAAQS.
23
No violations of the ozone NAAQS were monitored in Vermont for 1985.
The maximum daily values for the year were 0.115 ppm for Brattleboro
and 0.103 ppm for Burlington. Ozone levels have remained relatively
stable in Vermont since 1981 and show attainment.
