1984 ANNUAL REPORT ON AIR QUALITY
IN NEW ENGLAND
This report represents 1984 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 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 nonattainment, 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 (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.
Table 2 shows the number of stations violating the National Ambient
Air Quality Standards (NAAQS) and the total number of stations reporting
data during 1984. There were no stations in violation of the 24-hour
primary S02 standard, the 3-hour secondary S02 standard, or the annual
primary S02 standard. For particulates, four stations were in violation
of the 24-hour primary standard, and sixteen stations were in violation of
the 24-hour secondary standard. The annual primary standard was violated
at one station. Nine 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 N02 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 S(>2 and NC^). 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 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 eight 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 1 audit program for TSP,
SC>2, CO, N02, 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 mentoring sites which show a linear regres-
sion of the deseasonalized monthly means for TSP, S02, 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.

1984 PRECISION AND ACCURACY DATA
Current Federal Regulations require that each State report both pre-
cision and accuracy data for all data from National Air Monitoring sites
(NAMS), and State/Local Monitoring Sites (SLAMS). Tables 9 and 10 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 9 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 1984 national statistics are included on Tables 9 and 10.
Generally, precision and accuracy values were slightly worse than
those in 1983, possibly reflecting aging equipment and the increased
size of the networks. Significant improvements were noted, however, in
the TSP and lead precision data from Connecticut and the lead precision
data from New Hampshire and Rhode Island. Areas where the total range
exceeds 25% and improvements are needed include: Connecticut's precision
data for S02 and N02 and accuracy data for CO, S02, and N02; Maine's
precision data for TSP; Massachusetts' precision data for N02, 03, and
TSP and accuracy data for N02 and 03. In addition, Maine failed t0
report any accuracy audits for CO for 1984, although their precision
data is satisfactory. Similarly, Rhode Island submitted no accuracy
data for N02 during 1984 due to failures in their audit equipment.

REGION I 1984 PERFORMANCE AUDIT PROGRAM
Region I conducts an audit program to determine the performance of
ambient air monitoring systems and to provide their operators with tech-
nical assistance in improving data quality. Continuous air monitors are
audited by allowing them to sample gas mixtures containing known concentra-
tions 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 143 audits were conducted in the six New England States
for TSP, S02, CO, N02, and 03 by personnel from Region I. In general, the
results were very good with 133 audits (93%) satisfactory, 8 audits (6%)
marginal, and only 2 audits (1%) unsatisfactory. This indicates a slight
decline from the 1983 results.
TSP audit results showed a substantial decline over 1983 during which
2% of the audits were marginal. In 1984, 7% were marginal, although none
were unsatisfactory. One possible reason for the decline may be the incon-
sistencies in some of the State procedures for computing flow rates which
were permitted under the earlier TSP Reference Method regulations. All of
the States in Region I have adopted or are planning to adopt revised TSP
procedures consistent with the current EPA requirements which should yield
better results.
Performance on N0£ audits improved again with all completed audits
meeting satisfactory criteria.
Ozone audit results were generally good with only one marginal audit
in Massachusetts.
S02 audit results were satisfactory with the exception of two failures
in Maine and two marginal audits in Massachusetts. Region I provided Maine
with assistance in diagnosing the possible cause of failure.
Results for CO were generally good in all States audited. The remainder
were all satisfactory. Table 8 summarizes the results of the audit program
on a state-by-state basis.

AIR QUALITY 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 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, CO, and SC>2 sites. Due to an insuf-
ficient data base, these programs were not employed for Pb, 03, and N0£.
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 1980—1984) 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,
CO and S02 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; 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 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.

-------
1984 CONNECTICUT AMBIENT AIR QUALITY SUMMARY
TSP
There were no violations or exceedences of either the primary or
secondary National Ambient Air Quality Standards (NAAQS). The highest
annual geometric mean was measured in Bridgeport and was 52 ug/m^ or
69% of the primary NAAQS. Annual geometric means were 67% of the stan-
dard in Stamford, 64% in Hartford, and 63% in Waterbury. The maximum
second highest daily average was measured in Bridgeport and was 46% of
the primary daily NAAQS. The second maximum daily average in the larger
urban areas ranged from 24% to 46% of the primary daily NAAQS. Rural
background levels were approximately 31% of the annual primary standard
and 48% of the secondary daily standard. In general, the 1984 TSP levels
were approximately the same as those reported in 1982 and 1983.
The five-year trend lines were prepared for 19 sites and are con-
sidered representative of the entire State. Ten sites had decreasing
trends between the 90% and 100% confidence level. Nine sites had no
significant trends but did show a definite negative slope. The trend
lines for both Bridgeport and Hartford are shown in Figure 2.
Lead
There were no violations to the NAAQS reported in 1984. The highest
quarterly average was measured in Waterbury and was only 47% of the NAAQS.
Maximum quarterly averages in other urban areas ranged from 10% to 45% of
the standard. In general, lead levels are slightly lower than those
reported in 1982 or 1983.
CO
There were no exceedences or violations to the one-hour NAAQS
reported in 1984. Both Hartford and Stamford reported violations of the
8-hour NAAQS. The levels for CO were slightly lower in 1984 than in
1983 or 1982 in New Britain and New Haven. Bridgeport CO levels in 1984
were slightly lower than those reported in 1983 and slightly higher than
in 1982. Stamford recorded higher CO values in 1984 than in 1983 and
slightly lower levels than in 1982. A new microscale site in Hartford
has reported 13 exceedences of the 8-hour NAAQS during 1984 compared to
three in 1983 and two in 1984 at the old CO site.
74
-------
Five-year trend lines for New Britain and Stamford show a significant
decreasing trend. The Bridgeport, New Haven, and Hartford five-year trends
show a significant increasing trend. The Stamford CO site is included in
Figure 3.
S02
No violations or exceedences to the NAAQS were measured in 1984. The
maximum SC>2 annual averages occurred in Bridgeport, Milford, and New Haven
and were approximately 43% of the NAAQS. Annual averages were 39% of the
annual NAAQS in Hartford, 40% in Stamford, and 36% in Waterbury. The
highest daily S02 levels were measured in New Haven, the maximum being 67%
of the NAAQS. The second highest daily averages measured in the major urban
areas were approximately 55% of the daily NAAOS. In general, the 1984 S02
annual averages were approximately the same or slightly lower than in 1982 or
1983; also, the maximum and second highest daily averages in general were
somewhat higher in 1984 than in either 1982 or 1983. The five year trends
for seven sites were analyzed. Sites in Danbury, Bridgeport (Hallet
Street), Hartford, New Haven, and Waterbury showed a significant decreasing
trend. The Milford site showed a slightly positive nonsignificant trend,
while Stamford showed a negative nonsignificant trend plot. Figure 4 shows
the Bridgeport (Hallet Street) trend line.
N02
The three N02 SLAMS sites which are located in Bridgeport, East
Hartford, and New Haven reported values of 52%, 40%, and 58%, respectively of
the annual standard. N02 values at these three sites are slightly down
from those values recorded in 1983. The five-year trend plots for the three
N02 sites were analyzed. Bridgeport showed a significant decreasing trend,
while New Haven showed a slightly negative nonsignificant trend, and East
Hartford's four-year trend plot showed a positive nonsignificant trend.
75
-------
Every site in Connecticut reported between 7 days and 28 days over the
primary NAAQS. The maximum daily reading was .232 ppro in Stratford during
1984. In general, the ozone levels were lower in 1984 than in 1983 and
slightly higher than the 1982 values. Figure 5 shows a plot of the number
of days over the standard for the Bridgeport and Stratford sites.
76
-------
1984 MAINE AMBIENT AIR QUALITY SUMMARY
TSP
Primary National Ambient Air Quality Standards (NAAQS) violations
were measured in Augusta, Presque Isle, and Washington County. Secondary
standards violations were reported in Augusta, Jay, Lincoln, Madawaska,
Millinocket, Old Town, Oxford County, Presque Isle, Washington County,
and Westbrook. An exceedence was reported in Bangor and Rumford. There
were no violations of the annual standard. The annual geometric mean
was 84% of the NAAQS in Westbrook, 67% in Augusta, 65% in Millinocket,
48% in Jay and 56% in Lincoln. The TSP site with the best air quality
was Acadia National Park which reported levels 17% of the annual NAAQS.
The five-year trend analysis was performed on 47 TSP sites in Maine.
Of these 47 sites, four showed significant increasing trends. Twelve
sites showed no significant trends, and the remaining 31 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 several years. Several sites
showed higher values than those reported last year. Figure 2A shows
decreasing five-year trend lines for Augusta and Lincoln.
Lead
There were no violations of the quarterly lead NAAQS. The highest
statewide concentration was measured in Portland (microscale site) and
was 73% of the standard. Last year's maximum level was 96% of the NAAQS
at the Portland site. Maximum levels measured in Augusta were 61% of
the standard in 1984, while levels in Auburn were 51% of the standard.
Although maximum values increased slightly in Augusta since last year,
lead levels generally followed a decreasing trend throughout the State.
CO
The only CO monitoring site in the State was located in Portland.
The site was moved from Bangor in 1984. Reported CO levels in Portland
were slightly higher than the levels meassured in Bangor last year. The
77
-------
highest concentration was 31% of the 1-hour NAAQS, and for the 8-hour
NAAQS, the highest concentration was 79% of the standard. These levels
occurred with less than a full year of monitoring data. CO levels state-
wide generally show a decreasing trend, assuming maximum values do not
increase once a full year of monitoring data is collected.
S02
The highest daily SC>2 levels were monitored in Rumford. The values
were approximately 62% of the 24-hour standard. Monitored values in
Portland were 41% of the standard, while Lewiston, Lincoln, and Washington
County showed values of approximately 42% of the daily standard. The
highest 3-hour levels were monitored in Mexico at 56% of the standard.
Rumford measured values 49% of the standard, and Levels in Madawaska were
48% of the standard. Although maximum SC>2 values in Maine are only 62%
of the NAAQS, a review of the historical data base shows mixed trends.
The five-year trend analysis was conducted for 13 sites. Seven sites
showed decreasing trends, while four showed no significant trends, and two
sites (Lincoln and Mexico) showed increasing trends. The trend lines for
Millinocket show a 46% 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 80% reduction as a result of reduced fuel burning
activity at a local mill. Figure 4 shows a reducing trend line for
Madawaska.
N0?
Maine is not required to monitor N02J however, at present, one special
purpose NC>2 site is operating in Portland. This site is gathering infor-
mation for an ozone study.
03
Of the six sites operated in Maine, only two monitors measured NAAQS
violations. The Cape Elizabeth site measured six days over the standard,
while the York County site measured eleven days over the standard. Acadia
78
-------
National Park and the Washington County sites measured one day over the
standard. The Gardiner and Lincoln county sites had no monitored or pre-
dicted violations in 1984. The highest value recorded (.171 ppm) was
measured at the Cape Elizabeth site. The site measuring the lowest
values was located in Lincoln County. This site measured a maximum value
of .119 ppm or 91% of the NAAQS.
In general, ozone values and the number of days over the standard
decreased from 1983 results. However, the frequency of violations at
the York County site increased from seven in 1983 to eleven in 1984.
Figure 5 shows a plot of the number of days over the standard for the
Cape Elizabeth site.

1984 MASSACHUSETTS AMBIENT AIR QUALITY SUMMARY
TSP
There were no reported violations to the primary or secondary National
Ambient Air Quality Standards (NAAQS) in 1984, although secondary NAAQS
exceedences were reported for four sites: Boston, Pittsfield, Springfield,
and Worcester. TSP sites with the highest annual geometric means were
located in Boston at 75% of NAAQS, Chelsea at 72% of NAAQS, Springfield at
65% of NAAQS, and Worcester at 73% of NAAQS. The highest second-high daily
TSP values were measured in Boston at 88% of the secondary NAAQS, in Chelsea
at 79% of the NAAQS, in Pittsfield at 77% of the NAAQS, in Springfield at
84% of the NAAQS, and in Worcester at 98% of the NAAQS. Rural background
levels were 39% of the primary annual, 37% of the primary daily, and 65% of
the secondary daily standards.
In general, TSP levels in 1984 showed a continued downward trend for
most sites in the State. A total of 22 sites were analyzed for five-year
trends. Of these, 16 sites (73%) showed a significant downward trend, one
site (5%) showed a significant upward trend and five sites exhibited no
significant trends.
The five-year trend lines for the Southampton Street site in Boston and
Howard Street site in Springfield are presented in Figure 2A. These two center
city urban sites are representative of the significant downward trend that
most TSP sites are experiencing in Massachusetts.
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. Lead
levels averaged 15% lower in 1984 than in 1983 at five of the six sites.
The remaining site, East Columbus Avenue in Springfield, experienced a slight
increase (3%) over 1983 levels. This site also recorded the maximum quarterly
lead level for the State at 86% of the NAAQS, an increase of 29% over the
corresponding quarter for 1983.
80
-------
CO
Four of the eight sites which monitored this pollutant in 1984 recorded
violations to the primary 8-hour NAAQS: Boston with three violations, Lowell
with four violations, Springfield with four violations, and Worcester with
two violations. None of the eight sites reported exceedences to the 1-hour
primary NAAQS. Maximum and second maximum CO levels for both the 1-hour and
8-hour averaging times decreased at all four Boston sites by an average of
30% between 1983 and 1984. The remaining four sites in other urban areas
of the State experienced average increases of 35% for these averaging times.
Five-year trends were analyzed for the seven sites which had sufficient
data. All four sites in Boston exhibited significant decreasing trends,
while a site in Worcester exhibited a significant increasing trend. The two
remaining sites, both located in Springfield, did not exhibit any significant
trends. Figure 3 depicts the five-year trend line for the Commonwealth
Avenue site in Boston. Neighborhood (suburban) CO levels were 35% and 73%
of the 1-hour and 8-hour NAAQS in Boston, and 29% and 73% of the NAAQS in
Springfield. The maximum second-high 1-hour and 8-hour averages for the
State in 1984 were measured at the Old City Hall site in Lowell at 63% and
128% of the NAAQS, respectively.
S02
There were no violations of the NAAQS at any of the 18 sites which
reported S02 data for 1984 in Massachusetts. The maximum S02 site in the
State for 1984 was the Commonwealth Avenue site in Boston with levels of 54%
of the annual standard and 52% of the daily standard reported. The 1984
annual average at this Boston site was significantly lower than previous
years, although the maximum daily levels were higher in 1984 than previous
years. Figure 4 depicts the five-year trend line for the Commonwealth Avenue
site and indicates a significant downward trend.
After Boston, the next highest annual mean concentrations were measured
in Fall River, Lawrence, and Springfield at approximately 40% of the annual
standard. All three areas experienced increases in both the annual mean and
daily S02 levels in 1984 over previous years' levels. Minimum S02 levels
in Massachusetts were measured at a rural background site in Medfield with
levels at 25% of the daily standard and 16% of the annual standard.
81
-------
A total of 15 sites were analyzed for five-year trends. Signifi-
cant downward trends were identified at nine sites located in Chicopee,
Fall River, Lowell, Medfield, Springfield, Watertown, and three sites
in Boston. A significant upward trend was identified for a site in
Springfield. The remaining five sites did not exhibit any significant
trends.
N02
In 1984, ten sites collected N02 data in Massachusetts. The maxi-
mum site in the State was located in Boston where the annual mean for
1984 was 83% of the NAAOS and represents an increase of 73% over the
1983 levels at this site. A 27% increase in the annual mean was measured
at the other Boston site in 1984 and represents 61% of the NAAQS. N02
levels in Springfield and Worcester did not appreciably change between
1983 and 1984. The other sites in the network did not have sufficient
monitoring records to determine if changes have occurred in the past
year. A five-year trend analvsis was performed on three sites which
had a sufficient sampling record. No significant long-term trends were
identified for these three sites. The minimum levels for this pollutant
were measured at a site in Fall River at 28% of the NAAQS.
"3
As in past years, violations continue to be reported throughout
Massachusetts. Violations were recorded at 11 out of 14 sites which
operated in 1984. Sites in Pittsfield and Lawrence did not record any
values greater than the NAAQS. A site in Newburyport reported one
daily exceedence of the standard.
In general, ozone levels decreased in 1984, with nine sites averag-
ing decreases of 15% in the maximum and second maximum daily values in
1984. Four other sites measured average increases of 9% in maximum and
second maximum values. The total number of days in excess of the stan-
dard for the 13 sites, which operated in both 1983 and 1984, was reduced
from 89 days in 1983 to 45 days in 1984. Nine sites recorded reductions
in number of days over the NAAQS, while two sites, Attleboro and F.aston
saw minor increases. Two other sites, Newburyport and Ware, saw no
change in number of days over the standard.
82
-------
The maximum daily values for 1984 were recorded in Chicopee at
0.209 ppm, Fairhaven at 0.206 ppm, and Ware at 0.204 ppm. The Massa-
chusetts site with the roost number of days over the standard for 1984
is in Fairhaven with nine days. This was also the case in 1983 with
the Fairhaven site recording 17 days over the standard. The areas
which experienced the lowest maximum daily values for 1984 are located
in Lawrence at 0.112 ppm, and Pittsfield at 0.117 ppm. Figure 5 shows
the 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.

1984 NEW HAMPSHIRE AMBIENT AIR QUALITY SUMMARY
TSP
The only site which reported a violation to the primary National
Ambient Air Quality Standards (NAAQS) was the Berlin, Lancaster Street
trailer site. This site measured three values over the 24-hour standard,
and the site also measured a violation to the annual NAAQS. The Lancaster
Street site measured six values over the primary 24-hour standard in 1983.
A primary and secondary NAAQS exceedence was measured in Dover in 1984.
The only secondary standards violations in New Hampshire were measured
in Berlin. The air quality in Berlin is influenced by manufacturing
activity at a local paper mill. The annual geometric mean was 67% of the
NAAQS in Portsmouth, 60% in Manchester, and 56% in Nashua. Background
levels in HoHis are 35% of the annual standard.
The five-year trend analysis was performed on 15 sites in New Hampshire.
Of the 15 sites, 12 showed significant downward trends, while the remaining
three showed no significant trends. Although levels generally decreased
throughout the State, values in Dover, Northumberland, and the Hollis back-
ground site showed higher levels than those reported in 1983. Figure 2A
shows a decreasing trend line for the Portsmouth Court Street site.
Lead
There were no lead violations reported in 1984. The highest site - a
microscale site in Concord - reported values 29% of the NAAQS. The lowest
site in the State, located in Berlin, had a maximum quarterly average of
9% of the standard. In general, lead values decreased from those reported
in 1983.
CO
No violations of the 1-hour NAAQS were reported in 1984; however, both
Nashua and Manchester reported violations to the 8-hour NAAQS. A total of
21 violations were monitored in Nashua. The maximum 8-hour level was 81%
over the standard. The frequency and magnitude of the violations are
approximately the same as those observed last year. Manchester recorded
eight violations of the 8-hour standard. The maximum value was 51% over
84
-------
the NAAQS. The magnitude of the violations in Manchester increased slightly
over the 1983 levels, and the number of values higher than the standard
increased substantially over the single exceedence measured in 1983.
S02
No violations to the NAAQS were monitored in 1984. The last violation
in New Hampshire was measured in Berlin in 1980. The highest state-wide
levels recorded during 1984 were monitored in Berlin. The values were 50%
of the 3-hour NAAQS. These levels resulted from local paper mill activity.
Metropolitan Manchester monitored levels 46% of the 24-hour standard, while
a Pembroke site, which is influenced by a utility company, measured levels
42% of the standard. In general, S02 levels in New Hampshire increased
from the values measured last year. However, long-term S02 trend lines
show either downward or no significant trend for the sites that were evalu-
ated. Figure 4 shows a downward trend line for the Northumberland, Groveton
Mobile Lab site.
NO 7
N02 data were not collected in 1984.
23
Of the five sites operated in 1984, Manchester and Nashua each reported
only one day over the standard. No other exceedences were recorded. The
highest state-wide value was monitored in Manchester and was 8% over the
NAAQS. The number of days over the standard decreased from three in Ports-
mouth in 1983 to zero in 1984. In general, ozone levels in 1984 were
similar to those recorded in 1982 and 1983. Figure 5 shows the number of
days over the standard for the Manchester site.

1984 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 1984. The
highest annual geometric mean occurred at the Westminster Street site in
Providence which was 71% of the annual primary NAAQS. This site also had
the second highest daily average which was 38% of the primary daily NAAQS.
The highest daily average was measured in Providence at the Bonanza Bus
Terminal site and was 87% of the secondary NAAQS. The rural background
site, located at the University of Rhode Island, Alton Jones campus in
Kent County, showed levels at 25% of the primary annual NAAQS and a second
highest daily average at 32% of the daily secondary standard.
TSP levels throughout the State have shown a gradual decrease from
1982 to 1984. The rural Alton Jones site, at 25% of the primary annual
standard, was almost equal to 1983's at 24%, and lower than 1982 at 27%.
The five-year trend analysis was performed for 12 TSP sites in Rhode
Island. Of these, 11 sites showed significant downward trends, while
only one site had no significant trend. Figure 2 shows the five-year
trend line for a typical site in Providence.
Pb
There were no calendar quarter arithmetic means greater than the
primary and secondary NAAQS in 1984. The highest quarterly lead average
occurred at Dyer Street and was 39% of the NAAQS. The second highest
quarterly average also occurred at Dyer Street at 36% of the standard.
The 1984 levels were generally lower than those in 1983 and 1982, and
the maximum rural background levels were 4% of the standard during the
highest quarter.
CO
There were no violations of the 1-hour primary and secondary NAAQS
in 1984. The microscale site in Providence at Dorrence Street reported
three violations of the 8-hour primary and secondary NAAQS in 1984
86
-------
versus two violations in 1983 and only one exceedance in 1982. At the
neighborhood site (Rockefeller Library), the second highest 8-hour concen-
tration decreased to 60% of the 8-hour NAAQS from 77% in 1983 and 64% in
1982. Figure 3 shows the five-year trend line for the microscale site in
Providence. This line shows a significant downward trend in the mean
levels of CO. The five-year trend line for the neighborhood scale site,
however, showed no significant trend.
SO?
No violations to NAAQS were reported in the last four years. The
highest levels reported in Providence during 1984 were approximatley 56%
of the 24-hour primary NAAQS. This is somewhat higher than either the
1982 or 1983 24-hour maximum values of 54% and 47% of the standard,
respectively. The second highest value reported in Providence in 1984
was 48% of the 24-hour standard which is also slightly higher than 1982
or 1983. Figure 4 shows a significant downward five-year trend line for
the mean SO? concentration at a Providence site.
NO?
The one site in Providence reported an annual average of 47% of the
NAAQS. This is slightly higher than the 1983 value of 45% of the stan-
dard; however, insufficient data from previous years precludes an accurate
five-year trend analysis.
The Kent County site reported 15 days during which the 1-hour NAAQS
was exceeded, while the Providence site only reported five such days.
The Kent County site has, over the past three years, had the most number
of measured days over the NAAQS. For 1982 and 1983, these same sites
reported seven and one day over the standard, respectively. The maximum
daily hour values were .215 ppm in 1984, .150 ppm in 1983, and .158 ppm
in 1982 at the Kent County site. Figure 5 shows a plot of the number of
days over the standard for the Kent County site.

1984 VERMONT AMBIENT AIR QUALITY SUMMARY
TSP
There was one exceedence of the primary and one violation of the
secondary National Ambient Air Quality Standard (NAAQS) in Barre and one
violation of the secondary NAAQS in Burlington (47 0140 005 F01). Burlington
also showed values approximately 59% of the annual geometric mean. Rutland
had the highest annual geometric mean which was 72% of the NAAQS (75 ug/m ).
The rural background site in Orange County reported levels 33% of the annual
geometric mean NAAQS. Maximum daily levels at this site were approximately
49% of the secondary standard.
A total of six sites were analyzed for their five-year trends. Of these,
five had significant downward trends: Barre, Bennington, Brattleboro,
Burlington, and Rutland. The Orange County trend plot showed a negative
86% decreasing trend from 1981 through 1984. 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 46% of the eight-hour standard. These levels are approxi-
mately the same as those measured in 1982 and 1983.
SO ?
The only site with a complete year's worth of data is Burlington. Data
from this site is 22% of the annual standard and 22% of the daily standard.
Reported daily values from Rutland and Barre are slightly higher than those
at Burlington. A five-year trend line for Burlington is shown in Figure 4,
indicating a nonsignificant trend with a slight negative slope.
88
-------
Vermont is not required to and does not conduct monitoring for NC>2.
03
There was one day over the NAAQS in Brattleboro and no reported
days over the NAAQS in Burlington. The highest daily value reported
in Burlington was 0.107 ppm or 86% of the standard. Higher levels
were reported during 1984 in Brattleboro and Burlington compared to
those values reported in 1982 and 1983.
