1983 ANNUAL REPORT ON AIR OUALITY
IN NEW ENGLAND
This report represents 1983 annual air quality information for all
states in New England. The majority of the data included in this report
was 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 Massachusetts
and New Hampshire, and from Maine’s licensing program which supplements
the state’s network.
This report is intended to list potential nonattainment areas for
planning purposes. The majority of data used has been evaluated and
verified by EPA; however, for the areas listed as nonattaintuent, the data
may require further evaluation by both EPA and the states.
Table 1 is a summary of the status of the National Air Monitoring
Sites (MANS) and the State/Local Air Monitoting Sites (SLANS) 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 slxws the number of stations violating the National Ambient
Air Quality Standards (NAAQS) and the total number of stations reporting
data during 1983. There were no stations in violation of the 24—hour
primary SO 2 standard, the 3—hour secondary SO 2 standard, or the annual
primary SO 2 standard. For particulates, five stations were in violation
of the 24—hour primary standard, and eighteen stations were in vfolatio i of
the 24—hour secondary standard. The annual primary standard was violated
at one station. Six 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—seven 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 MAAOS. 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 NAAOS by Air
Quality Control Region (AOCR), as well as the total number of monitors in
each AOCR. A map delineating the AOCRs in Region I 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 particulates at two sites;
for CO at one site; and for ozone at eleven sites.
Tables 6 and 7 list the precision and accuracy data submitted by the
six New England states. The 95% probability limits for five criteria
pollutants are given as a network average for each state.
Table 8 lists the results from the Region I audit program fo’r TSP,
SO 2 , O, 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—
if ied areas in which there were 1983 violations to NAAOS.
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 c seasonalized monthly means for TSP, SO 2 , and CO 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.

1983 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 (NANS), and as of January 1, 1983 for 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. 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
1983 national statistics are included on Tables 6 and 7.
Generally, precision and accuracy values were similar to those in
1982. Massachusetts, Maine and Vermont showed improvement in their
accuracy data for ozone. Massachusetts also reported improved NO 2
accuracy data. Areas where the range exceeds 25% and improvements are
still needed include Rhode Island’s SO 2 and NO 2 accuracy data, and Pb
precision data; Massachusetts’ ozone and TSP precision data; Connecticut’s
NO 2 , TSP, and Pb precision data; and New Hampshire’s Pb precision data.

REGION I 1983 PERFORMANCE AUDIT PROGRAM
Region I conducts an audit program to determine the performance of
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 mixtures containing known concentrations
of specific pollutants and noting the analyzers’ responses. High—volume
air samplers for TSP and lead 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 148 audits were conducted in the six New England States
for TSP, SO 2 , CO, NO 2 , and 03 by personnel from Region I and an EPA
contractor (RTI). In general, the results were very good with 140 audits
(95%) satisfactory, 6 audits (4%) marginal, and only 2 audits (1%)
unsatisfactory. In all cases, this represents an improvement over 1982.
TSP showed a substantial improvement over 1982 during which 5% of
the audits were marginal and 1.5% were unsatisfactory. In 1983, only 2%
were marginal and none were unsatisfactory.
Performance on NO 2 audits improved slightly with all completed audits
meeting satisfactory criteria. Three NO 2 monitors in Massachusetts,
however, were not audited because they were not operating at the time
that the audit was scheduled to occur.
The ozone audit results were generally good with 97% of the audits
being satisfactory, but the remaining two audits, both in Massachusetts,
were unacceptable.
Results for both CO and SO 2 were generally good with only two SO 2
audits rated as marginal. The remainder were all satisfactory. Table 8
summarizes the results of the audit program on a state—by—state basis.

AIR OUALITY SUMMARIES AND TRENDS
The next several pages contain a discussion of the air quality and
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 fulfil1i ent 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, CO, and SO 2 sites. Due to an insuf-
ficient data base, these programs were not employed for Pb, 03, and NO 2 .
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 1979—1983) 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 fluality Standards (NAAOS), geometric means are used
for TSP, while arithmetic means are used for the other pollutants. TSP,
CO and SO 2 trend lines for selected air monitoring sites are presented
in Figures 2 through 4.
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
deseasonalized linear regression lines would be of little value. Figure 5
shows a plot of the number of days over the standard for selected sites in
Bridgeport and Stratford, Connecticut; Cape Elizabeth, Maine; Medfield,
Massachusetts; Portsmouth, 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 meteor-
ology 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 mete-
orology rather than actual reductions in emissions.

1983 CONNECTICUT AMBIENT AIR OUALITY SUMMARY
TSP
There were no violations or exceedences of either the primary or
secondary National. Ambient Air Quality Standards (NAAOS). The highest
annual geometric mean was measured in Bridgeport and was 72% of the
primary NAAOS. Annual geometric means were 61% of the standard in
Hartford, 65% in New Haven, and 63% in Waterbury. The maximum second
highest daily average was measured in Bridgeport and was 43% of the
primary daily NAAOS. The second maximum daily average in the larger
urban areas ranged from 26% to 43% of the primary daily NAAOS. Rural
background levels were approximately 29% of the annual primary standard
and 40% of the secondary daily standard. In general, the 1983 TSP
levels were slightly lower than those reported in 1981 or 1982. The
five—year trend lines were prepared for 18 sites and are considered
representative of the entire state. Seventeen sites had decreasing
trends between the 90% and 100% confidence level. Only one site had
no significant trend but did show a slight negative slope. The trend
lines for both Bridgeport and Hartford are shown in Figure 2.
Lead
There were no violations to the NAAOS reported in 1983. The highest
quarterly average was measured in Waterbury and was only 56% of the
NAAOS. Maximum quarterly averages in the other urban areas ranged from
18% to 40% of the standard. The maximum quarterly average at any rural
background site was approximately 14% of the NAAOS.
Co
There were no exceedences or violations to the one—hour NAAOS
reported in 1983. Bridgeport, New Haven, and Stamford reported exceed—
ences, while both Hartford and New Britain had violations of the eight—
hour NAAOS. The levels for CO were generally higher in 1983 than in
1982 or 1981. At the Stamford site, however, the number of eight—hour
violations were reduced from 112 in 1981 to four in 1982, and there
were none in 1983. The five—year trend lines for Bridgeport, New
Britain, and Stamford show a significant decreasing trend. The Hartford
68

-------
and New Haven five—year trend lines show no significant trend. The
Hartford CO site is included in Figure 3.
No violations or exceedences to the NAAOS were measured in 1983. The
maximum SO 2 annual averages occurred in Bridgeport, Hartford, and Milford
and were approximately 45% of the NAAOS. Annual averages were 40% of the
annual NAAOS in Hartford, 37% in New Haven, and 23% in Waterbury. The
highest daily SO 2 levels were measured in Milford, the maximum being 52%
of the NAAOS. The second highest daily averages measured in the major
urban area were approximately 45% of the daily NAAOS. In general, the
1983 SO 2 annual averages were the same or lower than in 1981 or 1982;
also, the maximum and second highest daily averages in general were some-
what higher in 1981 than in either 1982 or 1983. The five—year trends
for eight sites were analyzed. Sites in Danbury, Hartford, New Haven,
Stamford, Bridgeport (Hallet Street), and Waterbury showed a significant
decreasing trend. The sites in Milford and Bridgeport (City Hall) showed
a significant increasing trend.
Figure 4 shows the Bridgeport (Haliet Street) trend line.
9 2
The three NO 2 SLAMS sites which are located in Bridgeport, East
Hartford, and New Haven reported values of 57%, 44% and 63%, respectively
of the annual standard. A trend analysis for Bridgeport and New Haven
showed significant decreasing trends. A trend plot for 1980 through
1983 in East Hartford was analyzed and showed an increasing trend. The
NO 2 trend analyses, however, were based on less than five years of data.
Every site in Connecticut reported between 15 days and 46 days over
the primary NAAOS. The maximum daily reading was 0.294 ppm. The maximum
daily reading was 0.274 ppm for 1981 and 0.233 ppm for 1982. Figure 5
shows a plot of the five—year ozone data versus the number of exceed—
ences for Bridgeport and Stratford.

1983 MAINE AMBIENT AIR OUALITY SUMMARY
TSP
Primary National Ambient Air Ouality Standards (NAAOS) violations
were reported in Bangor, Madawaska, Presque Isle, and Washington County.
A primary daily exceedence was measured in Augusta and East Millinocket.
Secondary standards violations were reported in Augusta, Bangor, Fort
Kent, Lewiston, Lincoln, Madawaska, Madison, Millinocket, Presque Isle,
Washington County, and Westbrook. An exceedence was reported in Auburn,
East Millinocket, Jay, and Waterville. The annual geometric mean was
65% of the NAAOS in Augusta, 67% in Bangor, 89% in Presque Isle, and 69%
in Westbrook. Similar TSP levels were reported in 1981 and 1982 in
Bangor, Presque Isle, and Westbrook. Annual levels decreased in Augusta,
Portland, and Lewiston. The TSP site with the best air quality was
Creasey Ridge Road, Mapleton, with reported levels of 17% of the annual
NAAOS.
The five—year trend analysis was performed on 21 TSP sites in Maine.
Of these 21 sites, none showed significant increasing trends. Four sites
showed no significant trends, and the remaining 17 sites showed a sig-
nificant downward trend. Figure 2 shows the five—year trend lines for
Bangor and Augusta.
Lead
Although there were no violations of the quarterly lead NAAOS, the
maximum concentration measured in Portland (microscale site) was 96% of
the standard. Maximum levels measured in Presque Isle were 62% of the
standard, while levels in Augusta were 46% of the standard. In general,
lead levels were similar to the levels reported in 1981 and 1982.
CO
The only CO monitoring site in the State was located in Bangor.
Reported CO levels were similar to levels measured last year. The high-
est concentration was 31% of the 1—hour NAAOS, and for the 8—hour NAAOS,
the highest concentration was 76% of the standard. The maximum levels
for 1981 were 36% of the i—hour standard and 94% of the 8—hour standard.
However, the five—year trend line for Bangor (see Figure 3) shows no
significant trend.
70

-------
No primary daily violations or exceedences of the NAAOS were measured
in Maine. SO 2 levels in Madawaska were approximately the same for 1981
and 1982 and reduced in 1983 with a maximum daily average of 353 ug/m 3 in
1981, 365 uglm 3 in 1982, and 238 ug/m 3 in 1983. In Millinocket, the addi-
tion of a new stack at a major industrial facility has reduced the number
of primary violations to zero. Maximum daily averages in Millinocket
were approximately the same for the last three years, with a maximum
daily average of 188 ug/m 3 in 1981 to 202 ug/m 3 in 1982, and in 1983 the
reported maximum value was 194 ug/m 3 . The annual SO 2 average in Portland
was 41% of the NAAOS and approximately 40% of the daily standard. The
Portland levels have been approximately the same for the last three years.
Figure 4 shows a significant downward five—year trend for Portland. In
addition, an SO 2 site in Madawaska and two sites in Millinocket all show
significant downward trends. However, the Route 2 site in Mexico showed
a significant increasing trend with only 60% data coverage over the five—
year period.
Maine is not required to monitor NO 2 ; however, at present, one special
purpose NO 2 site is operating in Portland.
Of the six sites operated in Maine, Acadia National Park, Cape
Elizabeth (Portland), Gardiner and York County sites reported more than
one day over the NAAOS. The Cape Elizabeth site reported nine days over
the standard. Acadia National Park and Gardner reported three days over
the standard, while York County reported seven days over the standard,
and Cumberland County and Hancock County reported only one day over the
standard. In 1982, the Cape Elizabeth site reported five days over the
standard, while Gardner, Hancock County and York County sites reported
one day above the standard. tn 1981, the site in Caribou reported a
maximum daily concentration of 58% of the NAAOS. For both 1980 and 1981,
this site reported the lowest 03 levels in New England. The Caribou site
was not operated in 1982. For 1982, the lowest site in Maine was at
Costigan which reported a daily maximum of 87% of the NAAOS. The lowest
site in 1983 was Cumberland County. Figure 5 shows a plot of the number
of days over the standard for the Cape Elizabeth site.

1983 MASSACHUSETTS AMBIENT AIR OUALITY SUMMARY
TSP
There were no reported violations to the primary National Ambient Air
Ouality Standards (NAAOS). Secondary standard exceedences were reported
in Boston and Pittsfield. The highest TSP site in Boston was 92% of the
primary annual NAAQS. The highest site in Springfield was 64% of the
primary annual NAAOS, while in Worcester the highest site was 65% of the
annual standard. Boston and Springfield data were generally lower in 1983
than In 1980, 1981, or 1982. In Worcester, TSP levels remained constant
for 1982 and 1983, although these levels are higher than in 1980 or
1981. Rural background levels were approximately 40% of the annual
primary and 33% of daily secondary standards.
A total of 22 sites were analyzed for five—year TSP trends. Of these,
14 showed a significant downward trend, and eight sites had no significant
trend. Of these eight, four sites located in Boston, Attlehoro, Lawrence,
and Medfield had a positive slope. The remaining four sites in Brockton,
Holyoke, Worcester, and West Springfield had a negative slope. The five—
year trend line for the Southampton Street site in Boston and Howard Street
in Springfield are included In Figure 2. Both sites had a significant
downward slope.
Lead
Lead monitoring began in both Boston and Springfield during 1982. No
violations to NAAOS were reported. In 1983 all lead sites showed a
decline over 1982 levels. The maximum site in Boston reported a value
38% of the standard, nearly a 100% decrease over 1982 levels. The maximum
site in the state was a Springfield site which reported a value of 67%
of the standard.
Co
Boston and Springfield reported violations to the 8—hour primary NAAOS
with a total of four violations recorded in each city. The Boston microscale
site showed significant decline with only one exceedence reported in 1983
down from 20 violations reported in 1982. One other Boston site and a
site in Worcester also reported an exceedence to the 8—hour standard. The
72

-------
CO sites at Commonwealth Avenue and 600 Washington Street, Boston and East
Columbus Avenue, Springfield, continued to report significant decreasing
five—year trends. No other sites had sufficient data for analysis.
Figure 3 shows the five—year trend for Commonwealth Avenue. Neighborhood
(suburban) CO levels were approximately 35% of the 1—hour standard and
72% of the 8—hour standard in Boston. These neighborhood levels are,
for the 8—hour averaging time, lower than 1982 levels.
There were no violations to any NAAOS reported in 1983. The maximum
State site, located in Boston, was 60% of the annual standard and 42%
of the daily standard. The 1983 annual average at this Boston site
(Commonwealth Avenue) was equal to the 1982 annual average and showed a
slight decrease from 1980 and 1981 levels. Figure 4 shows the five—year
trend line for this site which is a significant decreasing trend. SO 2
levels In Springfield and Worcester were approximately one—third of the
annual standard and 40% of the daily standard. Rural background levels
were approximately 20% of the annual and daily standards. These levels
are similar to the levels measured in 1981 and 1982. In addition to the
Boston Commonwealth Avenue site, a total of nine additional sites were
evaluated for five—year trends. Seven sites in Boston, Chicopee,
Fall River, Fitchburg, Springfield, and Watertown all showed significant
decreasing trends. Two other sites in Lawrence and Medfield had a non-
significant downward trend.
22
The Boston sites were 51% and 48% of the NAAOS in 1q83. The site in
Worcester was 34% of the standard for 1983. A new site in Springfield
reported 1983 levels at 46% of the standard. For 1982 only one site in
Boston had a valid annual average which was 43% of the standard.
9 -3
Violations continued to be reported throughout Massachusetts. Sites
in the Boston, Brockton, Lawrence, New Bedford, Pittsfield, Springfield,
and Worcester urban areas all reported violations. In general, the ozone
levels were much higher in 1983 than in 1981 or 1982, with the highest
second maximum day in the State measuring 0.185 ppm in 1983, 0.165 ppm
in 1981, and 0.162 ppm in 1982. Over the last four years, the city with
73

-------
the maximum number of measured days over the standard is in the Springfield
area. In 1983 Agawam reported 15 days over the standard in 1982, four days
over the standard in 1981, seven days over the standard, and in 1980 nine
days over the standard. In the Boston urban area, there were seven days
over the standard in 1982 versus three days in 1982 and two days in
1981. In Worcester, there were six days over the standard in 1983, one
day over the standard in 1982, and four days in 1981. Figure 5 shows
the five—year plot of the number of days over the standard for the
Medfield site which is located in the Boston urban area.

-------
1983 NEW HAMPSHIRE AMBIENT AIR OUALITY SUMNARY
TSP
The only site reporting violations to primary National n,bient Air
Ouality Standards (NAAOS) was in Berlin. There was a violation of the
annual standard and five daily violations at the Berlin, Lancaster Street
site. Secondary TSP violations were also measured in Berlin, and a
secondary exceedence was reported in Portsmouth. The annual geometric
mean in Manchester was 51% of the NAAOS. The rural background site in
Winchester reported a maximum daily level of 28% of the primary NAAOS.
In general, 1983 TSP levels were lower than 1982. Ten sites were analyzed
for trends. Of the ten, two sites had no significant trend. The remaining
eight all had significant downward trends. Figure 2 shows the five—year
trend line for the Court Street site in Portsmouth.
Lead
There were no lead violations reported in 1983. The highest site — a
microscale site in Concord — reported values 31% of the NAAOS. The lowest
site in the State, located in Berlin, had a maximum quarterly average of
5% of the standard.
CO
No violations to the 1—hour NAAOS were reported in 1983; however,
Nashua reported 20 violations, and Manchester reported one exceedence to
the 8—hour NAAOS. The site in Manchester reported significantly fewer CO
violations in 1983 compared to six violations in 1982. Nashua had higher
values and more frequent violations in 1983 as compared to 1982 when two
violations were recorded. However, the two violations were recorded at
the Nashua site with less than one—quarter of data in 1982. Based on
less than five years of data, the trend analysis for Manchester shows a
significant downward trend.
22
No violations to NAAOS were reported in 1983. The implementation of
a control strategy which included the use of taller stacks and a new hark
boiler at a major SO 2 source have resulted in no violations in Berlin
since 1980. In 1983, the maximum daily SO 2 concentration for Berlin was
75

-------
approximately 66% of the NAAOS. In Manchester, the maximum SO 2 levels
decreased frcmi 39% of the annual NAAOS in 1982 to 36% in 1983. The site
in Berlin reported the highest daily SO 2 concentrations for 1983. The
Groveton site reported the second highest level which was approximately
57% of the daily standard. A trend analyses was performed on six sites.
Of the six, the Manchester Spring Street site was the only site with
sufficient data to conduct a valid five—year analysis. However, the
Spring Street site showed no significant trend. Analyses, based on less
than five years of data, showed decreasing trends in Groveton and Berlin.
NO 2 data were not collected in 1983.
23
Portsmouth reported three days over the NAAOS, and Nashua reported
one day over the standard. No exceedences were reported in Berlin, Keene,
and Manchester. In 1982, both Manchester and Keene reported one day over
the standard. Portsmouth reported three days over the standard. Figure 4
shows the number of days over the standard for the Portsmouth site.

-------
1983 RHODE ISLAND AMBIENT AIR OUALITY SUMMARY
TSP
No violations to primary or secondary National Ambient Air Ouality
Standards (NAAOS) were reported in 1983. One exceedence, at the Bonanza
Bus Terminal site, of the secondary standard was reported in Providence,
and the annual geometric mean for that site was 76% of the NAAQS primary
standard. The rural background site, located at the University of Rhode
Island Alton Jones campus in Kent County, showed levels at 24% of the
annual NAAOS. TSP levels throughout the State were generally the same as
those in 1982 and lower than those in 1981. The annual geometric mean at
the Bonanza Bus Terminal site in Providence was 76% of the NAAOS primary
standard in 1982 and 81% in 1981, for example. The rural Alton—Jones
site values are slightly lower at 24% of the primary standard versus 31%
in 1982 and 36% in 1981.
A five—year trend analysis was performed for 11 TSP sites in Rhode
Island. All 11 sites showed a significant downward trend. Figure 2
slxws the five—year trend line for a typical site in Providence.
Lead
In 1983, the highest quarterly lead average was measured at the Dyer
Street site in Providence at 62% of the NAAOS primary standard. The 1983
levels were generally lower than those of 1982 and about the same as
those of 1981. The rural background site levels were 5% of the standard
during the highest quarter.
CO
No violations of the 1—hour NAAOS were reported. The microscale site
in Providence recorded three exceedences of the 8—hour NAAOS versus one
exceedence in 1982 and four in 1981. At the neighborhood scale site, the
maximum 8—hour concentration increased to 79% of the NAAQS from 71% in
1982 and 59% in 1981. Figure 3 shows the five—year trend line for the
microscale site in Providence and indicates a downward trend in the mean
levels of CO.
77

-------
No violations of the NAAOS were reported for SO 2 in 1983, 1982, or
1981. The highest levels reported in Providence during 1983 were a 24—
hour value of 46% of the NAAOS and an annual mean value of 34% of the
NAAOS which were somewhat lower than the values reported in 1982 and
1981. Suburban background values were approximately one—fourth of the
annual and daily standards as compared to approximately one—third in 1982
and 1981. Figure 4 shows a significant downward five—year trend for a
Providence site.
The one site in Providence reported an annual average of 45% of the
NAAOS. Insufficient data from previous years precludes an accurate trend
analysis.
9 -3
The Kent County site reported six days during which the 1—hour NAAOS
was exceeded, while the site in Providence reported one such day. In
1982, there were seven days during which the standard was exceeded in
Kent County and one in Providence; in 1981 there were nine days in
exceedence in Kent County and three in Providence. The maximum daily
hourly values at the Kent County site were 0.150 ppm in 1983, 0.158 ppm
in 1982, and 0.210 ppm in 1981.

1983 VERMONT AMBIENT AIR OTJALITY SUMMARY
TSP
There was an exceedence of the primary and secondary National Ambient
Air Ouality Standard (NAAOS) in Barre and an exceedence of the secondary
NAAOS in Brattleboro. Barre had the highest annual geometric mean which
was 75% of the NAAOS. A rural background site in Orange County reported
levels approximately 28% of the annual standard. Maximum daily levels at
this site were approximately 39% of the secondary standard. Data from
Burlington showed values approximately 50% of the NAAOS. There were no
apparent changes in TSP levels from those measured in 1981 or 1982.
A total of six sites were analyzed for the five—year trends. Of
these, three had no significant trends, but they did indicate a slight
negative slope. Bennington, Burlington, and Rutland all had significant
downward trends. Figure 2 shows the five—year trend line for Barre.
Lead
Vermont is not required to and does not operate a monitoring network
for lead.
CO
Maximum levels at the Burlington middle scale site were 22% of the
one—hour standard and 42% of the eight—hour standard. These levels are
approximately the same as those measured in 1981 and 1982. Figure 3
shows the five—year trend for Burlington. This trend shows no significant
downward trend.
The only site with a complete year’s worth of data is Burlington.
Data from this site is 16% of the annual standard and 25% of the daily
standard. Reported daily values from Rutland and Barre are slightly
higher than those at Burlington. A five—year trend line for Barre mdi—
cated an increasing trend, while Burlington showed a decreasing trend
line. Figure 4 shows a five—year trend line for Burlington.
92
Vermont is not required to and does not conduct monitoring for NO 2 .
79

-------
9-3
There were no days reported to be over the NAAOS. The highest daily
value recorded was 0.121 ppm or 97% of the stendard at the Brattleboro
site. The highest day in Burlington was 75% of the standard. Similar
levels were reported in 1981 and 1982.
