1975 ANNUAL REPORT ON
AIR QUALITY IN NEW ENGLAND
This report presents 1975 annual air quality information for all
states in New England. The data used are as submitted to EPA by the
states from their ambient monitoring networks in accordance with
40 CFR 51.7 . These data have not been evaluated or verified, as this
report is intended only to point out potential problem areas which
will, of course, require more detailed study.
TABLE 1 shows the number of stations violating the National Ambient
Air Quality Standards (NAAQS) and the total number of stations reporting
data during 1975. There were no violations of the SOS, standards. For
particulates, six stations were in violation of the 2 -hour primary
standard and forty stations were in violation of the 24-hour secondary
standard. The annual primary standard was violated at nine stations.
No stations violated the CO 1-hour primary standard, but twenty-one
stations were in violation of the 8—hour primary standard. For ozone,
every station in New England violated the standard except for the two
that did not report data for the sununer months (Berlin, New Hampshire
and Portland, Maine). Two stations violated the NO 2 annual standard.
TABLE 2 gives more specific information on those stations exceeding
the NAAQS. The information included is the number of violations, the
maximum and second high values, the dates of occurrence for those values
above the standards, and the annual means (geometric mean for TSP, arith-
metic mean or average for SO and NO 2 ). Those stations reporting a
maximum above the standards ut a second high below the standards are
included in this table. Also included are those stations (Kenmore Square
in Boston, Waterbury, Conn. City Hall, and the trailer site in Waterbury)
which have an annual mean above the standards but which do not have
sufficient data to meet the averaging criteria. (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 muse have two or more
values. For Continuous data, 757. of the year must be available to calcu- .
late a valid annual average.) Double asterisks are used in Table 2 and
in Table 3 to indicate sites that are likely to be in violation of annual
standards if sufficient data were available to calculate valid means.
They are Wellington Circle in Medford, Massachusetts, the trailer in
Bridgeport, Connecticut, and Clinton School in New Haven, Connecticut,
in addition to the three sites already mentioned.

-------
It should also be noted that 24-hour values above the standards
are not included in Table 2 if they are not midnight-to-midnight
values. A TSP reading of 293 ug/m was reported at Berlin, New Haxnp-
shire (Angel Guardian School) for a sample run from 2:00 p.m. on
October 30 to 2:00 p.m. on October 31. For SO 2 , the high 2 -hour
average at Bridgeport, Connecticut (City Hall) was 414 ug/m from
6:00 3 a.m. on March 7 to 6:00 a.m. on March 8. A second high of 407
ug/m occurred from 11:00 a.m. on August 31 to 11:00 a.tn. on September 1.
A legal interpretation of the 24-hour standard has been requested.
With regard to violations of SO 2 standards, a recent study by the
Environmental Monitoring and Support Laboratory, EPA, North Carolina,
suggests that bubbler data may be low by as much as 50%. Sites reporting
high 24—hour averages or annual averages within 50% of the standards are:
in Connecticut — Bristol City Hall, Hartford Health Lab (Clinton Street),
and the Stamford trailer on North Street; in Maine - Winslow Junior High
School and the site at Hathaway Shirt in Waterville; in Massachusetts —
Fall River Fire Station, Creenfield Police Station, and Holyoke (Canal
Street); in New Hampshire — Manchester Fire Station (Merrimack Street)
and Nashua Health Office (Mulberry Street) and in Rhode Island — the
Dyer Street site in Providence.
TABLE 3 lists every state site in New England. The information
presented compares the measured values to each NAAQS.
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 the report.
TABLE 5, Stations Where Readings Exceed Episode Levels, has been
developed to point out areas where emergency episodes are likely to occur.
When the specified concentrations are reached, if meteorological condi-
tions are such that these levels can be expected to persist for 12 hours
or more, or increase, an alert (warning or emergency) will be called. 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 particula 5 es at four sites; for SO 2 x TSP
(product of SO 2 concentration, in ug/m , and TSP), at one site; for CO
at •six sites; and for ozone at twelve sites.
Another area of increasing concern is that of calculating annual
means for data from stations with variable sampling frequencies. Since
some pollutant concentrations are seasonal, if the number of valid samples
varies substantially per quarter (due to voided samples, instrument mal-
function, or design of the sampling schedule), an annual mean weighing
each value equally will be biased. On the other hand, an annual mean

-------
calculated from the 12 monthly means should be more representative.
An addi ional station violates the TSP annual primary standard of
75 ug/m when the geometric mean is calculated using monthly means:
at Waltham, Massachusetts (Moody and Main Streets), where each quarter
is valid but the total number of observations in the first and fourth
quarters (when higher concentrations typically Occur) is 14 and the
second and third quarters 3 have a total of 26 bservations, the annual
geometric mean is 83 ug/m instead of 73 ug/m . For NOW,, one f the
two stations violating the annual primary standard of 1 O ug/m is no
longer in violation when the annual average is 3 calculated using mon hly
averages: the annual average becomes 100 ug/m instead of 102 ug/in at
Boston, Massachusetts (Kenmore Square), where the fourth quarter con-
tains only 11C/e of the total observations, in contrast to each of the
other three quarters which contain 277 , 327 , and 3O7 , respectively,
of the total observations. A legal opinion on this issue is forthcoming.
