PRELIMINARY 1990 OZONE CONCENTRATIONS COMPARED TO 1988 AND 1989
	(FINAL REPORT)	
The Headquarters and Regional National Air Monitoring Station
(NAMS) Coordinators have once again completed a nationwide survey
of preliminary summer ozone (03) data. This report represents 1990
ozone data as collected through October 31 and provides the summary
statistics from 600 of the approximately 770 (proposed for 1990
operation) nationally operating ozone monitoring sites. The data
were compiled by EPA Regional Offices through queries to State and
local air pollution control agencies in order to monitor the
severity of the 1990 ozone season.
To be expeditious in the reporting of the ozone data it must
understood that the data, as summarized in this report, were
gathered as they were being measured and therefore were not
subjected to the quality assurance (QA) procedures that State and
local air pollution control agencies normally apply. It must also
be emphasized that the data depicted in this report, have not gone
through the normal validation process, and as such are not suitable
for regulatory purposes. It is believed that the prescribed final
QA procedures are necessary before the data are suitable for
regulatory purposes.
This report compares the 1990 ozone data to the two previous
years, 1988 and 1989. The last four columns of Table 1 represent
the net change for each monitoring location from 1988 to 1989, and
1989 to 1990. Table 2 is a summary, by Regions, of the number of
1

-------
reported exceedances of the preliminary ozone concentrations
through October 31, 1990. Figures 1 and 2 illustrate the
comparisons between the number and percentages of reported ozone
standard exceedances to the number of reporting monitoring sites.
Figures 3 and 4 contrast these comparisons between the years 1989
and 1990.
SUMMARY
The preliminary ozone data as reported for the summer of 1990
were lower than concentrations reported in both 1989 and 1988. This
is attributed to the less elevated summertime temperatures and
stagnation of 1990 as compared to 1988 and to the near similar
(albeit slightly higher) range of summertime temperatures when
compared to 1989. An important factor to once again keep in mind,
was the difference in meteorological conditions between the summer
of 1988 and the summers of 1989/1990. It is well known that ozone
concentrations for 1988 were the highest in recent history,
particularly in areas east of the Mississippi River. As EPA
reported in the National Air Quality and Emission Trends Report,
1988, the summer of 1988 was the third hottest since 1931 and this
contributed greatly to the increase in 1988 ozone levels. In
contrast, meteorological conditions during the summer of 1989 were
not favorable for ozone formation. 1989 was reported to be one of
the wettest on record in nine States with numerous areas receiving
above average rainfall. 1990 summertime temperatures however,
averaged above the national mean with drier conditions over most of
2

-------
the county. While summer 1990 was reported to be cooler than 1988
though warmer and drier than 1989, preliminary ozone concentrations
were reported as averaging slightly lower than those recorded in
1989.
CONCLUSIONS
The analyses of the preliminary 1990 ozone concentrations have
resulted in the following assumptions:
1. For the approximately 550 sites that reported ozone
data in both 1989 and 1990 the daily peak measured ozone
concentrations through October 31 are, on a national
average, 2 percent lower than those reported in 1989.
2<. The 1990 daily second maximum peak ozone
concentrations through October 31 were 1 percent lower
than the corresponding values as reported in 1989.
3.	As was the case from 1988 to 1989, average decreases
from 1989 to 1990, while somewhat less, were once again
evident throughout the country, although there are again
mixed trends at some of the monitoring sites.
4.	The data as summarized in this report represent ozone
measurements from 600 sites, (78 percent) of the
approximately 770 (proposed in December 1989 for 1990
operation) operating nationally.

-------
CONCLUSIONS - continued:
5. An analysis indicates that while 369 sites (62
percent) report having no violations of the ozone standard
and 84 sites had but one exceedance (14 percent); 38 sites
had two (6 percent), 15 sites had three (<3 percent), 22
sites had four (<4 percent), 14 sites had five (2
percent), with 18 sites being reported as having between
six and nine (3 percent), while 40 sites (<7 percent): one
in New York, (at the World Trade Center, which is not used
for design values), nine in Texas and 30 in California
reported ten or more.
