Summary of State and Local Air Monitoring Stations (SLAMS)
This report is for calendar year 1986 and summarizes information
submitted to MDAD as of December 31, 1986. The information includes the
status of the National Air Monitoring Stations (NAMS) as well as the State
and Local Air Monitoring stations (SLAMS). Some of the changes which occurred
in 1986 and some of those planned for 1987 are tne result of the generic
revisions to 40 CFR 58 which were promulgated ,on March 19, 1986. The
definition of the urbanized area population was changed to specify the most
recent decennial U. S. Bureau of Census Report, which currently is the 1980
census. This affected the number of NAMS monitors for all pollutants because
the number of required monitors for ozone, carbon monoxide, nitrogen dioxide,
and lead in the urbanized areas are ba;sed upon population. The generic
revisions also changed the minimum population requirements for NAMS TSP and
SO2 monitors from 50,000 to 100,000. For these two pollutants the population
and the pollutant levels in each urbanized area affect the number of required
NAMS monitors. Because of these regulatory changes, the required number of
NAMS TSP and S0£ monitors decreased by 22 and 15, respectively, while the
required NAMS NO2, CO, O3, and Pb monitors increased by 2, 5, 3, and 8,
respectively. Although PM^g is not a criteria pollutant at this time, there
are PM^g samplers at 548 sites.
Table 1 provides a summary by Region, State, and pollutant for the number
of SLAMS monitors (excluding NAMS) operating in 1986 and planned for 1987, as
well as the operating NAMS in 1986 and required for 1987. Table 1 shows that
there were 4545 monitors operating on December 31, 1986, which is a decrease
of 129 from the 4674 monitors operating on December 31, 1985. A reduction
of another 145 monitors is anticipated during 1987 for a total of 4400.

-------
The pollutant with the largest change was TSP which decreased by 74
samplers (2424 to 2350). The TSP NAMS decreased by 22 and the SLAMS
(excluding the NAMS) decreased by 52 from 1785 to 1733. The NAMS samplers
are expected to decrease by 33 during 1987 from 617 to 584, while the SLAMS
(excluding the NAMS) is expected to decrease by 105 from 1733 to 1626. The
decrease may be larger than predicted, due to a delay (from the planned
March 1987 date) in the promulgation of the PM^g NAAQS.
The SO2 monitors show a decrease of 20.in 1986 from 1985 (544 to 524).
The NAMS monitors decreased by 15 (216 to 201) and the continuous SLAMS
(excluding the NAMS) decreased by 5 (322 to 317). An additional six SO2
bubblers are also operating. Fifteen SO2 monitors are expected to be
shutdown in 1987 which would result in 509 monitors operating.
The number of NO2 monitors decreased by 19 during 1986 from 246 to
227. Fourteen of the 19-monitor decrease was due to the discontinuance of
NO2 bubblers in Regions VI and VII. The number of NAMS NO2 monitors increased
by two because of changes in population of urbanized areas. The continuous
SLAMS (excluding the NAMS) decreased by seven (175 to 168). One additional
NO2 monitor is predicted to be discontinued in 1987.
CO is the only pollutant which showed an increase in monitors in 1986
from 1985 where three new monitors became operational (440 to 443). The
NAMS monitors increased by five from 112 to 117 due to changes in population
of the urbanized areas. The SLAMS (excluding the NAMS) decreased by two
from 328 to 326. One additional CO monitor is expected in 1987.
There were 18 fewer O3 monitors in 1986 than in 1985 (617 to 599).
The NAMS O3 monitors increased by three from 215 to 218 because of changes
in the population of urbanized areas, while the SLAMS (excluding the NAMS)
2

-------
decreased by 21 (402 to 381). There are 11 new O3 monitors which are
scheduled to be operational in 1987.
The Pb samplers show a decrease of one in 1986 (403 to 402). The
number of NAMS increased by eight from 105 to 113 due to changes in population
of the urbanized areas. The SLAMS (excluding the NAMS) decreased by nine
from 298 to 289. One; less Pb sampler is expected to be operational in 1987.
The highlights for each Region are discussed below.
Region I - For the Region, there were two less monitors operating in 1986
than in 1985 (250 to 248) because of an increase of two SLAMS monitors and
a decrease of four NAMS monitors. The number of monitors planned for 1987
is 247, or a decrease of one monitor.
Connecticut has seven more monitors in 1986 than were operating in
1985 which were all Pb SLAMS. Two CO NAMS monitors are planned for 1987.
Maine had one new O3 monitor in 1986. Massachusetts shows ten fewer SLAMS
monitors operating in 1986 than in 1985 which included four SO2 and three
O3 monitors. Also, three TSP and one SO2 NAMS monitors were discontinued
in 1986. New Hampshire put into operation during 1986 two TSP, one SO2,
one N02» and one Pb SLAMS additional monitors. Rhode Island has discontinued
one SO2 SLAMS monitor in 1986 and plans to discontinue three TSP SLAMS
samplers in 1987. There is no change to the Vermont network.
Region II - There are 302 monitors operational for Region II, which is a
decrease of six from the 308 monitors operating in 1985. Four of the six
monitors are SLAMS and two are NAMS monitors. There are 292 monitors
planned for 1987 which is a decrease of ten from the 312 monitors operating
in 1986.

Pennsylvania operated four more TSP, one SO2, and one Pb monitor and four
fewer NOg monitors in 1986 than in 1985. The Virginia network shows a net
decrease of two SLAMS monitors due to a reduction of five TSP monitors and
an increase of one SO2 and two O3 monitors. One TSP NAMS sampler was
discontinued in 1986.
