ABSTRACT
This report presents a comprehensive tabulation of the nation's air
quality and monitoring activities for 1974. These summaries are based
on data acquired through extensive monitoring activities conducted by
Federal, state and local air pollution control agencies, and compiled
according to the nation's 247 Air Quality Control Regions. Information
is provided on the five pollutants for which National Ambient Air Quality
Standards have been set (suspended paniculate matter, sulfur dioxide,
carbon monoxide, oxidants, and nitrogen dioxide). Analyses of pollutant
trends are presented for the period 1970-1974, plus a discussion of non-
urban ozone and estimates of nationwide emissions for the period 1970-1974.

MONITORING
AND AIR QUALITY
TRENDS REPORT, 1974
1. INTRODUCTION
1.1 GENERAL DESCRIPTION
Progress toward achieving compliance with the National Ambient
Air Quality Standards (NAAQS) is measured through the collection and
analysis of air quality data. These data are obtained by state and
local control agencies through their monitoring activities, and are
forwarded to the U.S. Environmental Protection Agency (EPA). This
report, the fourth in a series issued by EPA , summarizes (1) the
air quality data collected in 1974 and (2) the scope of monitoring
activities for that year. Trends in air quality over recent years
are discussed at length in two sections of this report. Other sections
treat selected aspects of data interpretation.
Data are included in this report on five of the six pollutants
for which NAAQS have been set: total suspended particulate matter
(TSP) , sulfur dioxide (SO,-), carbon monoxide (CO), oxidants (0 ),
& X
and nitrogen dioxide (NO_). As yet, no reference method has been
designated by EPA for NO,,; the data presented in this report were
obtained by one or more of eight methods that are regarded as candi-
dates for the reference method or as possible equivalent methods.
The nonmethane hydrocarbons guide (NMHC) is used for meeting
oxidant standards because of the relationship between emission of
hydrocarbons and the production of oxidants; but monitoring of hydro-
carbons is not currently required. Thus, no information is given in
this report for this group of pollutants.
The principal sources of air quality data in 1974 were the many
monitoring networks operated by or responsible to the state air pol-
lution control agencies. Data acquired through these state-supervised
-------
monitoring networks must be submitted quarterly to EPA's National
Aerometric Data Bank (NADB). This schedule is designed to facilitate
periodic appraisal, nationwide, of progress in implementing the mon-
itoring networks themselves and progress toward achieving the air
quality standards. According to this schedule, data for a calendar
quarter are to be submitted through one of EPA's ten Regional Offices,
entered in the data bank, and made accessible for summarization within
120 days after the close of that quarter.
The summaries in this report reflect all 1974 data received by
September 1, 1975.
Reporting stations have been included in the data tables in the
Appendices if they have submitted at least three sample values from
monitors which collect an integrated sample over a 24-hour period or
at least 400 hourly values from a continuous monitor.
Annual means of pollutants have been calculated only if four
valid quarters of data have been collected and reported. A tentative
annual mean (followed by a question mark) is calculated if at least
two but fewer than four valid quarters of data are present.
Extraordinarily high maximum values have been flagged (#) in the
Appendices of this report. Some may be the consequence of measurement
or data processing errors; some may be legitimate values. This is the
only publication in which such values will be flagged as being suspect.
Because it is the responsibility of the agencies submitting the data
to check suspect values and delete erroneous ones, routine data re-
trievals from EPA's National Air Data Bank will not identify these
potentially anomalous values.
The monitoring results reported here are by no means comprehensive.
For example, diffusion modeling of emissions from large point sources
of SO- indicates areas in which violations of NAAQS have probably
occurred, even though no actual monitoring data have been reported.
Also, data from some short-term or sporadic monitoring for such
purposes as special studies and complaint investigations are usually
not submitted to the National Air Data Bank because the data are not
extensive enough to provide equitable comparisons with routine data
from permanent monitoring sites.
The special topics section of this report contains a review of
urban-nonurban oxidant investigations and a summary of estimated
nationwide emissions for 1970 through 1974.

2. SUMMARY
Air quality in the United States in 1974 was in many respects
similar to that reported for 1973. Air Quality Standards were exceeded
at approximately the same percentage of reporting stations, with one
exception: there was an evident decline in the proportion of stations
at which the 8-hour carbon monoxide standard was exceeded.
The dicussion that follows is presented in condensed form in
Table 2-1.
The primary annual standard for total suspended particulates (TSP)
was exceeded at 23 percent of the high-volume air sampler (high-vol)
stations reporting a valid year's data (467 out of 2004) in 1974.
(A valid year of data is defined as a data record containing at least
five 24-hour samples in each quarter or 75 percent of the possible
hourly values from a continuous monitor.) These 467 stations represent
111 Air Quality Control Regions (AQCRs) in which the annual particulate
standard was exceeded. This is 56 percent of the 198 AQCRs reporting
at least one station with valid yearly data. All 247 AQCRs, however
should be reporting at least one such station.
The primary 24-hour standard for TSP was exceeded at less than
one-tenth of all high-vol stations reporting326 out of 3788, in-
cluding stations reporting minimal* data; however, these 326 stations
represent some 40 percent of the AQCRs reporting such data (99 out of
236) .
The annual sulfur dioxide (SCO standard was exceeded at only
3 percent of the stations** reporting valid annual means (31 out
of 1030) ; these stations represent 11 out of 155 AQCRs reporting a full
*At least three 24-hour high-vol or bubbler samples, or 400 hourly
values from continuous monitors.
**These figures on SCu violations may be subject to reevaluation
if they were based on measurements taken with 24-hour bubbler samplers,
Preliminary results from a current review of this sampler's chemistry
indicate that elevated temperatures inside the sampler box may result
in the underestimation of ambient concentrations.

Each of the 247 AQCRs should have at least one station for TSP and SO-.
Total number of reporting stations given includes those stations reporting minimal data for
1-hour, 8-hour, or 24-hour measurements.
-------
year's data for at least one station. As with particulates, all 247
AQCRs should be operating at least one sulfur dioxide monitoring
station full-time.
The 24-hour S02 standard was exceeded at less than 5 percent of
all reporting stations99 out of 2241, including stations reporting
minimal data. These 99 stations represent 22 of the 210 AQCRs report-
ing such data.
Carbon monoxide (CO) data were reported from 377 stations in 92
AQCRs. The 1-hour CO standard was exceeded at 27 stations, or 7 percent,
in 13 AQCRs; the 8-hour CO standard was exceeded at 211 stations, or
56 percent, in 58 AQCRs.
Oxidant/ozone (Ox/0,) data were reported from 343 stations in 86
3
AQCRs; the 1-hour standard was exceeded at 273 of those stations, 80
percent, representing 76 AQCRs.
Nitrogen dioxide (NO_) measurement methods are still being reviewed
for the purpose of redesignating a Federal reference method. Valid
annual data for NO_ are reported for 582 stations. The method used
by these stations are deemed candidates for the status of reference
or equivalent methods. These stations represent 101 AQCRs. The
currently defined annual standard for NO- was exceeded at only 18
stations in 4 AQCRs.
Difficulty by many monitoring stations in acquiring or reporting
a full year's data continues to handicap the evaluation of the nation's
...air quality. From the preceding paragraphs it can be deduced that of
the 3788 TSP monitoring stations and 2241 SO- monitoring stations
reporting minimal data in 1974, only 53 percent and 46 percent, respec-
tively, reported data sufficiently complete to permit calculation of a
valid annual mean. Not only can the annual standards for these pol-
lutants be evaluated at only about half the existing stations, but
the incidence of 24-hour standard violations remains indeterminate
wherever the data record is incomplete. Thus, expediting the flow of
data from the state and local monitoring agencies to EPA's national
data bank is being given increased emphasis.
Historical trends in air quality levels afford a convenient
guide to determining progress in the control of air pollution. For
some pollutants, lack of historical data on a national basis limits
the inferences that may be made. The recent expansion, however, of
air pollution monitoring networks is resulting in data that will serve
as a baseline for future trend assessment. Currently, a good historical
data base on the national level is available for total suspended parti-
7
-------
culates and sulfur dioxide primarily in urbanized areas. For oxidants,
carbon monoxide, and nitrogen dioxide, historical data are limited and
their geographical distribution is very sparse. Therefore, trends
for these three pollutants are considered as a series of special
cases. The present status of historical data reflects the evolution
of air pollution monitoring efforts. For the most part, initial ef-
forts were concentrated on the assessment of total suspended particu-
lates and sulfur dioxide in center-city areas.
Based on composite averages from 1096 sites, total suspended
particulate levels have improved from 1970 to 1974. During this period,
3 3
the composite annual average declined from 80 yg/m to 66 yg/m . This
is an overall decrease of 17 percent, or slightly less than 5 percent
per year. This improvement was generally reflected throughout the
nation, but specific localities are still experiencing TSP levels in
excess of the national ambient air quality standards. The principal
sources of the problem are (1) fugitive particulate emissions from
various industrial processes; (2) wind-blown dusts from barren terrain,
plowed fields, dirt roads, etc., primarily a problem in western states;
and (3) the miscellaneous detritus more typical of eastern cities, a
sort of urban background that includes salt and grit from, the treat-
ment of snowy streets, secondary particulates formed in reactions
among gaseous pollutants, and re-entrained particulates from paved areas
and roof tops. In spite of continued NAAQS violations, particulate
emissions are estimated to have declined 29 percent from 1970 to 1974.
Sulfur dioxide levels have declined from an annual composite
3 3
average of 38 yg/m in 1970 to 26 yg/m in 1974, according to data
from 258 sites. This represents an overall decrease of 32 percent
or approximately 9 percent per year. Over 90 percent of these sites,
however, are located in urbanized areas and caution must be used in
generalizing these results. During this time period, estimated emis-
sions decreased 8 percent. The much greater reduction in ambient S02
levels may reflect a shift in SOx emissions away from center-city
areas, where monitoring sites are concentrated. Thus, the overall
decline in S02 levels may be the combined result of emission reductions
and redistribution of emissions. The data for 1975 are expected to
show additional decline in SO2 emissions in response to The Clean Air
Act's mid-1975 compliance deadline for meeting air quality standards.
Carbon monoxide trends in the few cities for which there are his-
torical data suggest general improvement. This is consistent with the
estimated emission reduction for this period. Although peak concentra-
-------
tions have shown little or no decrease in the majority of urban areas,
the 8-hour standard has been the more serious problem and there is
clear evidence of a reduction in the incidence of violations of that
standard. Data from the states of California, New Jersey, New York,
and Washington show improvement in the percentage of the time the
8-hour standard is exceeded. Data from Los Angeles and New Jersey
indicate that the percentage of time the 8-hour CO standard was ex-
ceeded was reduced by approximately one-half from 1970 through 1974,
going from about 12 percent to 6 percent. The state of Washington
showed consistent progress during the 1971 through 1973 period, and
New York State and San Francisco data showed that less than 0.5
percent of the 8-hour values were in excess of the standard. Nationally,
the number of CO monitoring sites increased consistently from 1970
through 1974, having grown more than 400 percent between 1970 and
1974 and 25 percent from 1973 to 1974.
California is still the primary source of good historical data
on oxidants. Oxidant trends in California continue to show long-term
improvement in both peak values and in the incidence of violations.
Data from the Los Angeles and San Francisco areas show decreases of
20 to 50 percent in the number of times the 1-hour oxidant standard
was exceeded. Recent studies have shown that high oxidant levels are
widely distributed, extending even into rural areas. This spatial
distribution is an important aspect of the oxidant problem. One of the
special topics in Section 5 of this report deals with a study of photo-
chemical oxidant concentrations in rural versus urban areas. In the
future, broader interpretations of ambient oxidant levels should be
possible because of the expansion of oxidant montitoring networks.
The number of oxidant or ozone monitoring stations increased almost
600 percent nationally between 1970 and 1974.
Nitrogen dioxide emissions have increased nationally about 10
percent since 1970. Upward trends of approximately 30 percent in ambient
concentrations of NO2 have been reported in two specific urban areas,
Los Angeles and Philadelphia since the mid-sixties. Because of recent
changes in measurement methodology for monitoring nitrogen dioxide,
few areas have sufficient historical data with which to assess NO2
trends for 1970 through 1974. Between 1973 and 1974, however, the
number of stations reporting a complete year of acceptable N02 data
increased by almost 800 percent, so that future reports should be
able to assess more accurately the national trends in NO- levels.

One of the special topics included in this year's report is a
discussion of air pollutant emissions. Nationwide estimates of pol-
lutant emissions from 1970 through 1974 show steady declines in the
tonnage of particulates and carbon monoxide being dumped into our
air. The two principal categories of particulate emissions
stationary-source fuel combustion and industrial processesshowed
reductions of some 30 percent for this 5-year period. Carbon monoxide
emissions from motor vehicles, which are responsible for three-fourths
of the total CO emissions, were reduced by 10 percent.
Emissions of sulfur oxides fluctuated, but ended the 5-year
period with a 10 percent decrease in emissions from the dominant
category, stationary-source fuel combustion.
Hydrocarbon emissions showed a small overall decline, the com-
bined result of a more than 10 percent decrease in the principal
category, motor vehicles, and increases of smaller magnitude in other
categories.
Nitrogen oxides showed an increase of about 10 percent. The
majority of the increase came from motor vehicles, although the other
principal category of NO emissions, stationary-source fuel combus-
X
tion, also showed an increase.

3. STATUS OF AIR QUALITY AND MONITORING ACTIVITY
The majority of the summaries in this report deal with data for
the calendar year 1974. Most of the data summarized are the product
of measurements of pollutant concentrations in the ambient air taken
by state and local monitoring networks. These data are submitted to
EPA's National Aerometric Data Bank (NADB) for assessments of nation-
wide progress in achieving and maintaining air quality standards
(Table 3-1). The assessments presented here are based on data incorpor-
ated in the NADB as of September 1, 1975. Since these assessments are

based only on air quality data reported to EPA, fewer ACQRs will be
shown in violation here than in "attainment/non-attainment" evaluations,
because the latter also draw upon diffusion modeling of source emissions
and other information to estimate ambient pollutant levels where moni-
toring data are unavailable.
The nationwide status of air quality in 1974 is presented in
two principal ways: (1) a summary of data from all reporting stations
and (2) a summary of data from the 247 Air Quality Control Regions that
encompass the 50 states, 4 territories, and the District of Columbia
covered by the Clean Air Act. Detailed summaries of 1974 data re-
ported from individual stations within each AQCR are presented in the
appendices.
Two tables, 3-2 and 3-3, presenting a 5-year perspective (1970 -
1974), show some increases in the numbers of stations now on record
for prior years compared with the number shown in previous reports;
the numbers in these tables, therefore, supercede the numbers in pre-
vious annual reports. Some of the increase results from additional
submitted data; some increase results from a change in the criterion
for including a station in the total. Previous publications listed
only stations reporting at least one quarter's valid data* in a
calendar year. The new criterion accepts any station reporting at
least three 24-hour values from a manual method (high volume or
bubbler) or 400 hourly values from an automated (continuous) monitor
in a calendar year. The choice of three 24-hour values virtually
eliminates the scattering of miscoded samples that show up as spurious
sites having usually one, sometimes, two samples. Three such samples,
if collected consecutively on the "every sixth day" schedule prescribed
by the reference methods, would encompass a 13-day period. In very round
numbers, 400 hourly values represent a similar period of time. This
change arises from the recognition that if even such a limited data
record contains values that exceed a short-term standard, this consti-
tutes information, albeit limited, on the existence of a problem area.
Obviously, the absence of violations in such partial data warrants no
conclusive claim for compliance with a standard.
* At least 5 values from a manual-method, 24-hour monitor- equitably
distributed in the quarter; or at least 75 percent of the possible
hourly values from a continuous monitor.

The nationwide status of monitoring activity is summarized in the
last part of this section. A minimum number of monitors is required
2
in the Air Quality Control Regions of each state . An accounting of
these AQCR requirements versus the number of monitors actually reporting
data is summarized for each state, for the 10 EPA Regions, and for the
nation as a whole in Section 3.6.
3.1 NATIONAL SUMMARY OF AIR QUALITY BY STATION
A general picture of national air quality is obtained from the
number of reporting sites at which ambient pollutant concentrations ex-
ceeded the standards (Table 3-2). In addition to the totals for 1974,
Table 3-2 includes figures for the previous 4 years, 1970 through 1973.
This conveys some essential historical perspective on the increase in
the number of monitors in recent years as well as the number of mon-
itors at which air pollution exceeds standards.
It is important to keep in mind, when reflecting on the changing
percentage of stations where standards were exceeded each year, that
the number of monitoring stations has increased substantially in 'this
5-year period. Changes in the percentage of stations that reported
values exceeding the standards could be largely a consequence of a
shifting balance in the types of stations reporting. Also, administra-
tive changes occasionally result in mid-year transfers of stations to a
different identification code, which causes such stations to be counted
twice, thus inflating annual totals. Of course, when a station is
physically moved, a new site code is essential. To separate these
effects from true changes in air quality requires the examination of a
subset of stations that have reported data throughout the period, as
is done in Section 4 of this report.
In 1974, the primary annual standard for suspended particulates
was exceeded at some 23 percent of all hi-vol stations reporting valid
annual data (467 of 2004 stations). This is a decrease from 1970,
when approximately 50 percent of the stations reporting at that time
(385 of 763) recorded values that exceeded the annual standard. The
24-hour primary TSP standard has characteristically been exceeded at
substantially fewer stations than has the annual primary standard. Of
the total number of stations reporting at least minimal data (3 or more
samples per year), TSP stations at which the 24-hour primary standard
14
-------
was exceeded have declined from about 16 percent in 1970 (212 of 1283)
to less than 9 percent (326 of 3788) in 1974.
Among sulfur dioxide monitoring stations reporting a valid year's
data, concentrations at approximately 3 percent (31 of 1030) exceeded
the annual SO2 standard in 1974. The percentage of stations at which
the annual standard was violated decreased from 16 percent in 1970
to its present plateau in 1972. At about 5 percent (99 of 2241) of
all SO^ stations reporting at least minimal data (3 or more bubbler
samples or 400 hourly values), the 24-hour SO- standard was exceeded
in 1974. This percentage has changed little since 1971, declining
from 11 percent in 1970.
These figures on SO- violations may be subject to reevaluation
where they are based on measurements taken with 24-hour bubbler
samplers. Preliminary results from a current review of the bubbler's
chemistry indicate that elevated temperatures inside the sampler box can
convert some portion of the collected SO2 into an insoluble compound.
The resulting decrease in the apparent S0_ concentration is 'variable,
depending on both temperature and the time the collected sample remains
in the box.
The carbon monoxide standard most frequently exceeded "'is the
8-hour standardat 56 percent of CO monitoring stations reporting in
1974 this standard was violated.* The 1-hour CO standard was exceeded
at only 7 percent of these stations.
The 1-hour oxidant standard was exceeded at 80 percent of the
stations reporting in 1974, and the rate has fluctuated around this
value since 1970.
Nitrogen dioxide monitoring technology has been in a state of
flux since revocation of the initially designated reference method
(Jacobs-Hochheiser Method). The presently defined annual standard
for NO- was exceeded at 5 percent of the stations using methods which
are candidates for reference or equivalent methods and reporting a full
year's data.
*See Section 3.4 for a description of the "different-day, second-
high value" interpretation of the 8-hour CO standard used in this report,

3.2 POPULATION-ORIENTED AND SOURCE-ORIENTED MONITORING STATIONS
The TSP and S0_ monitoring stations are sufficiently numerous to
afford a broad comparison between population-oriented stations and
source-oriented stations. (The last two digits in a station's SAROAD
code identify a station's project function: 01 = population-oriented,
02 = source oriented). Although some sites are in complex neighborhoods
where the balance between population and source influence requires some
subjective judgment in the choice of a station's designation, the
national composites reveal some interesting contrasts.
Figure 3-1 presents the percentage of population- and of source-
oriented particulate stations at which primary standards were exceeded.
In addition to the national composites, the two groups of stations with-
in Standard Metropolitan Statistical Areas (SMSAs)* are in turn grouped
into three population categories in this figure. The population-oriented
stations show an increasing percentage of annual standard violations with
increasing SMSA population. A consistently higher percentage of the
source-oriented TSP monitoring stations reported violations of both the
annual and the 24-hour primary standards.
Data from sulfur dioxide monitors exhibit patterns (Figure 3-2)
that differ from those of TSP data. First, the percentage of stations
at which the annual or the 24-hour primary S0~ standard was exceeded
is substantially smaller than for the particulate standards. Further,
in contrast to TSP, it is the 24-hour SO- standard that is more often
exceeded. As might be expected, the 24-hour standard is exceeded by
a higher percentage of source-oriented SO- stations than population-
oriented stations. The opposite is true for the annual S02 standard-
it was exceeded by a larger percentage of the population-oriented groups.
Table 3-3 further subdivides the SO stations according to their
use of 24-hour bubblers or continuous instruments. Understandably, a
larger proportion of violations of the 24-hour standard are recorded
by the continuous instruments. The continuous instruments are, by
intent at least, in operation every day, while the periodic sampling
*An SMSA is, basically, a county or group of contiguous counties that
meets certain criteria of population size, metropolitan character,
and economic and social integration with the central city. In New
England, towns and cities are used to define SMSAs.

3.3 NATIONAL SUMMARY OF AIR QUALITY BY AQCR
The status of the nation's 247 Air Quality Control Regions (AQCRs)
with respect to National Ambient Air Quality Standards is summarized
in Table 3-4 for 1970 through 1974. The increasing number in recent
years of AQCRs with stations at which certain standards were exceeded
(24-hour primary TSP and S0_ standards, for example) may appear to
contradict reports of improving air quality. In fact, examination of
trends later in this report confirm downward trends at stations with
a good historical record of measurements. The contributing effect seen
in Table 3-4 is the result of expansion of monitoring activity over this
5-year period, which adds previously unmonitored areas to the list of
AQCRs in violation. While the number of AQCRs having violations of
standards is beginning to show some decreases in 1974, it should be
kept in mind that a single high station can keep an AQCR in the violation
category even though substantial portions of the AQCR may have achieved
significant improvements.

3.4 DISTRIBUTION OF AQCRs WITH RESPECT TO STANDARDS
To be included in the analysis for short-term standards (1-hour,
8-hour, or 24-hour), an AQCR must report at least one station with at
least three 24-hour values from a manual method (hi-vol or bubbler),
or at least 400 hourly values from an automated (continuous) monitor,
as appropriate. The station with the largest "second-high" value
determines an AQCR's position in the distribution. Stations with
flagged (#) values (see Appendices) are not used.*
To be included in the analysis for annual standards, an AQCR must
report at least one station with a complete year's data (4 valid quarters)
The station with the highest annual mean determines an AQCR's position
in the distribution. AQCRs lacking sufficient data in either of the
above groups are relegated to the "no data" category.
Such an analysis potentially masks some substantive distinctions
between AQCRs. For example, two AQCRs with ten monitors each may rank
equally, on the basis of maximum values reported; yet the other nine
reporting stations in each network may reveal quite contrasting condi-
tions in the remainder of the two regions. The question of how to
comprehensively yet succinctly characterize AQCRs with diverse network
sizes, situated in diverse topography and operating in neighborhoods
of diverse complexion under the influence of diverse meteorology, remains
unreconciled. Nevertheless, as long as one reporting station in an AQCR
registers values in excess of a standard, that AQCR will be grouped in
the violation category. Therefore, this presentation uses the station
reporting the highest values in an AQCR to show the AQCR standing with
respect to a standard, but it does not convey the extent of the area
in which the standard is exceeded.
The TSP data show contrasting profiles for the AQCRs having TSP
concentrations above and below the 24-hour and annual primary standards
(Figure 3-3a) . The majority of AQCRs are reporting second-high 24-hour
values within the standard, yet a significant group of 15 have reported
values in excess of the standard by a factor of three or more. On the
other hand, over half the AQCRs with complete annual stations are re-
porting annual means above the primary annual standard, yet only one
ranges as high as three times that standard.
*Flagged values are only tentatively suspect. Responsibility lies with
the submitting agency to review and delete where appropriate. Subse-
quent retrievals will not include the flag.

Figure 3-3 (continued). Distribution of AQCRs according to reported values exceeding National Ambient Air Quality
Standards, 1974 (based on maximum values reported).
-------
Most AQCRs reported sulfur dioxide data, Figure 3-3b, within both
the 24-hour and the annual standards. Among the AQCRs in which S02
standards were exceeded, the 24-hour standard was exceeded in more
AQCRs than the annual standard.
These comparisons of AQCR distributions for 24-hour versus annual
standards for TSP and S02 are not as useful as they might be since the
numbers of AQCRs in each group are unequal. Because of incomplete TSP
data, only 84 percent of the AQCRs appraised for the 24-hour standard
can also be appraised for the annual standard; for SG>2/ only 74 percent
have annual as well as minimal 24-hour data. Some apparent differences
may thus be at least a partial artifact of different group sizes and
composition.
For carbon monoxide (Figure 3-3c) even minimal data can provide
a comparable appraisal of both the 1-hour and the 8-hour standards.
Therefore, the same AQCRs are included in both distributions* and the
validity of the contrast is unqualified. Violations of the 8-hour
standard for cumulative exposure clearly occur more widely than vio-
lations of the higher 1-hour standard for acute exposure. The 8-hour
standard is also likely to be exceeded by a larger factor.
Notice should be taken of the manner in which the 8-hour CO
averages are interpreted in this report. First, running 8-hour averages
are calculated for each station and the number of these averages ex-
ceeding the standard is reported as a measure of cumulative exposure
potential (see Appendix C). Then, a station's second-highest 8-hour
average, as reported in Appendix C, is drawn from a different day than
the maximum value. This "different-day" second-highest value has been
used here to determine whether a station is in violation and to assign
an AQCR's position in Figure 3-3c. The results of this simple procedure
appear to approximate closely those that would be obtained from the
more elaborate proposal for searching out a non-overlapping second-
highest 8-hour value.
The 1-hour oxidant standard was exceeded in 1974 in most of the
AQCRs where measurements were taken76 of 86 (Figure 3-3d) . The second-
highest value ranged over the standard by a factor of four in 10 AQCRs.
Nitrogen dioxide monitors with valid annual means were reported from
101 AQCRs; of these, only 4 AQCRs reported violations of the NO? annual
standard. The majority of the reporting AQCRs had NO- concentrations
below the standard by the comfortable margin of 40 percent or more.
*With the exception of two AQCRs in Michigan, where data problems thwarted
calculation of 8-hour averages.

3.5 FIVE-YEAR SUMMARY OF AQCR STATUS
Table 3-5 presents a 5-year summary (1970-1974) of the number of
stations reporting data for each pollutant from each of the 247 AQCRs,
and the number of stations at which respective standards were exceeded.
On the same line with each AQCR number and name, under each
pollutant, the figure in parentheses is the minimum number of monitoring
stations required for that pollutant as specified in the Federal
5
Register .
Two different station counts are used in Table 3-5: the columns
headed "# STA(l)" contain the number of stations reporting a valid
year's data (at least five 24-hour values each quarter, representatively
distributed; or 75 percent of the possible hourly values in each quarter);
the columns headed "#STA(2)n contain the number of stations reporting
at least minimal data (at least three 24-hour values or 400 hourly
values). In previous publications, this second category was defined
as including stations with at least one valid quarter's data. This
new criterion means that more stations are being included.
Only values reported from stations with a full year's data can
be judged against an annual standard. All valid annual data plus
partial data can be judged against a short-term standard, although
obviously, when incomplete data show no violations of a short-term
standard, this result must be regarded as inconclusive. Further, the
status of an AQCR must be considered inconclusive if the number of
stations reporting a valid year's data is less than the minimum number
required.
Occasionally, a question mark will appear in a column for the
number of stations at which an annual standard is exceeded. This
indicates that only tentative means rather than validated means are
above the annual standard in that AQCR. Tentative means have been cal-
culated for the first time in this report and are based on two or three
valid quarters. In the appendix tabulations of individual stations,
these tentative means are identified with a question mark. These
stations are not counted in the number of stations reporting valid
annual means, nor are tentative annual means above the standard counted
as confirmed violations.
The remaining columns in Table 3-5 list the number of stations
where standards are exceeded with respect to each pollutant, as
explained in Figure 3-4. The values of those standards are included
in the headings, in both micrograms per cubic meter (yg/cu.m.)

CO STANDARDS ARE IN MILLIGRAMS PER CUBIC METER
-------
milligrams per cubic meter for CO (mg/cu.m.) and in parts per million
(ppm).
Diligent scrutiny will reveal that a few stations are counted in
violation of a standard, yet the appendix table will show the deter-
mining value just equal to the standard. The comparison with the
standard is made with values containing decimal places that are not
printed; thus, the violation consists of only a fraction of a microgram.
For example, a hi-vol station may show an annual mean of 75, yet be
counted technically in violation because that mean is actually some
value like 75.3.
3.6 STATUS OF MONITORING ACTIVITY BY STATE AND BY EPA REGION
As in the other sections of this report, monitoring stations are
counted if they have reported "minimal" data; that is, at least three
values from manual-method, 24-hour monitors (hi-vols and bubblers) or
at least 400 hours from automated or continuous monitors. Station
totals for prior years will not necessarily match previously published
figures both because of these revised criteria and because some addi-
tional data have been belatedly submitted since the completion of the
last annual report.
Table 3-6 lists the number of TSP, SO-, CO, oxidant, and N02
monitors reporting in each state. Sulfur dioxide monitors are sub-
divided into bubbler (24-hour) and continuous (hourly) monitors.
The four columns under each pollutant heading show (1) the number
of monitors required to satisfy minimum Federal requirements; (2) the
number of monitors actually reporting at least minimal data; (3) the
number of required monitors actually reporting to EPA; and (4) the per-
centage of the required monitors actually reporting. Note that there
are separate requirements for SO- bubblers and for S0_ continuous in-
struments. Bubblers are specified where the annual standard is of
principal interest; continuous monitors are specified where short-term
standards are the principal interest. In some instances, agencies have
chosen to install continuous instruments in place of bubblers. A
separate column under "SO- Bubblers" shows the percentage of required
monitors reporting when these continuous monitors are credited toward
bubbler requirements.
In some instances, the number of monitors reporting equals or
exceeds the minimum number required for a state; yet the completion

status appears in the table as less than 100 percent. This simply
indicates that at least one AQCR within that state still does not
have the minimum required number of monitors.
The minimum required number of monitors for each AQCR is included
in Table 3-5. In interstate AQCRs, the total required stations are
apportioned among the component states according to the population in
each state portion of the AQCR.
Table 3-7 summarizes the total stations reporting compared with
the number of stations required and with the required stations actually
reporting for each of the 10 EPA Regions.
Table 3-8 identifies the number of stations monitoring each
pollutant according to the method or principle being used. The pre-
ponderance of air monitoring is being conducted with reference methods
or with methods based on reference-method principles. These are the
sole members of the "approved" category at present. Other methods
that are not reference methods but are considered reasonable candidates
for passing equivalency tests are listed as "unapproved." The "Unac-
ceptable" category includes those methods or measurement principles
that are generally acknowledged to be inaccurate and obsolete.

4. TRENDS IN CRITERIA POLLUTANTS
This section discusses trends in the criteria pollutants: total
suspended particulates, sulfur dioxide, oxidants, carbon monoxide, and
nitrogen dioxide. The previous section covered nationwide air quality
with respect to the National Ambient Air Quality Standards (NAAQS) and
examined the available data on a calendaryear basis. For the discus-
sion of trends, however, only those sites having data with historical
continuity are considered. Therefore, this analysis uses data from
fewer sites than given in the previous section and, as a consequence,
gives a less detailed picture of the current status of air pollution
with respect to standards. The pollutant trends are presented on a
national basis and also on a regional basis. The data base used for the
analysis is discussed, with particular attention given to how well the
data sample represents the nation. In addition, possible meteorological
influences on air quality trends are briefly discussed. Although there
are many ways of looking at trends in air quality, the primary emphasis
in this section is to discuss trends with respect to the National Ambient
Air Quality Standards since the passage of the Clean Air Act of 1970.
4.1 NATIONAL OVERVIEW
In a discussion of air quality trends, it is reasonable first to
summarize the information on a national level. The purpose of this
section is to give a general overview; later sections will present more
detailed information concerning the nature of the data base and regional
trends. As mentioned earlier, the time period of interest for this
report is 1970-1974. The selection of 1970 as the base year was influ-
enced by the amount of data available and the fact that the Clean Air
Act of 1970 provides a convenient frame of reference for discussion of
trends in the 1970's. It should be noted, however, that while 1970
represents a convenient reference point for considering recent trends,
many localities showed considerable improvement in air quality prior to
69
-------
this date. The progress made in the late 1960's has been discussed in
previous editions of this report
Sufficient data by which to determine trends on the national level
are available only for TSP and S02> Historical data for CO, oxidant,
and N0~ are available only for limited geographical areas and, therefore,
trends in these pollutants are examined only on a regional basis.
Figure 4-1 displays the median and the 10th and 90th percentiles
of the quarterly means and maximums for TSP and SC>2 data on a national
level. Running four-quarter averages of the percehtile values are .also
shown to smooth out the seasonal variation that occurs in pollutant
concentrations. These graphs are based upon data from 1096 sites for
TSP and 258 sites for SO2, these sites having been chosen from the
National Aerometric Data Bank on the basis of availability of historical
data. The selection criteria employed are discussed in the next section.
As shown in these graphs, the general trend in air pollution for the
1970-1974 period has been downward. In all cases, the 10th percentile
indicates a fairly stable pattern for the lower values while the decrease
in 90th percentiles shows improvement at the sites with higher values.
The median values for TSP show improvement in both mean and maximum
values over the 5-year period. For SO-, the median is fairly stable
but is well below the standard. The graphs suggest that although there
has been overall improvement for both these pollutants since 1970, little
or no change has occurred in the past 2 years.
While the graphs of Figure 4-1 give a convenient summary of the
general trends in the nation, an alternative approach is to compare
the 1970-1971 period with the 1972-1974 period and to tabulate how many
sites show improved air quality. This is done in Figure 4-2, which
shows the percentage of sites at which TSP and SO.., concentrations in-
creased or decreased by more than 10 percent between these two time
periods. In this computation, interpolated values were substituted for
missing quarters, according to the scheme discussed in Section 4.3, in
order to assure balanced seasonability- Here again, the results indicate
the general improvement that has occurred on the national scale. For
both TSP and SO-, considerable progress has clearly been made with respect
to mean levels. Although the net effect indicates overall improvement
in maximum values, there appears to be much more fluctuation, which is
not surprising for extreme values. For the purposes of this report,
trends in maximum values will not be treated in further detail. One
reason for this is that in the past few years many sites have increased
their sampling frequency from biweekly to every sixth or every third day,

-------
This increase in sampling frequency would be expected to complicate an
analysis of maximum values by increasing the probability of detecting
the highest values. Any apparent trend would include an indeterminate
component resulting from the more comprehensive sampling schedule,
confounding the effect of any real environmental change.
In considering a national overview for TSP and SO2 trends, the
previous figures have combined data from various types of sites.
Figure 4-3 displays the composite averages for the same data, strati-
fied by population. The population figures were taken from the
Standard Metropolitan Statistical Areas (SMSA) in which the sites are
located. These SMSAs are used by the U.S. Bureau of the Census and
provide a convenient means for summarizing data by population category.
As these graphs indicate, air quality is improving across all population
categories for TSP; however, for SO-, while the overall trend is down,
the smaller-sized cities show a slight increase. Although many of these
sites were in the North Central and Midwest, there does not appear to be
any specific geographical grouping. At most of these sites, means are
well below the annual standards despite these increases. Later sections
will present further stratifications of the data to examine the major
components of national trends.
4.2 METEOROLOGICAL FACTORS AFFECTING AIR QUALITY TRENDS
In considering air quality trends, the effect of meteorology is
important. One reason for examining air quality trends is to see if
genuine improvement is being made because meteorological phenomena
over a given time period may mask actual trends. A study was conducted,
therefore, to examine seasonal patterns and trends in meteorological
parameters on a scale comparable to that of air quality parameters.
To accomplish this, meteorological data for 1970 through 1974 were
selected from National Weather Service observation stations most
representative of the dominant SMSAs within each of 5 major geographic
regions of the U.S. (as discussed in sections 4.4 and 4.5). Wind
speed, rainfall, and temperature were selected for analysis because
of their generally accepted relationships with ambient air quality
and their amenability to large-scale regional analysis. Quarterly
and annual averages were computed for the meteorological parameters in
the same manner as for the air quality data.

4.2.1 Regional Meteorological Trends
In general, dispersion is enhanced and pollutant levels are lower
at higher wind speeds. Conversely, dispersion is limited and pollutant
levels tend to be greater at low wind speed. Examination of the data
indicates that wind-speed conditions that enhance dispersion tended to
occur during the winter and spring seasons; whereas those conditions
limiting dispersion were experienced mostly during the summer and fall.
In addition, the higher maximum and minimum quarterly average wind
speeds observed in the Northeast, Midwest, and Central Plains indicate
that these areas had the most favorable wind-speed conditions for dis-
persion; whereas the Southeast experienced the least favorable.
The seasonality of rainfall was most distinct in the western half
of the nation; in the East, however, no distinct seasonal patterns were
observed. Rainfall is important in relation to air quality because it
can remove particulates from the atmosphere. In general, the eastern
half of the nation received more rainfall annually than the western
half did during the 1970-1974 period. This, together with the observed
seasonal patterns in the West, suggests that rainfall may more favorably
influence annual air quality in the East, but may be more significant
to variability in pollutant levels in the West.
The importance of these effects becomes clear when the seasonality
of rainfall is examined together with that of wind speed. For example,
the greater amounts of rainfall in the Southeast may partially have
negated the unfavorable effects on dispersion of the observed low wind
speeds. More significantly, in the Southwest and plains region, high
wind speeds had a tendency to occur during the same seasons as low
rainfall. This combination may have increased the amount of fugitive
dust in the atmosphere and thereby unfavorably influenced air quality.
The distribution of quarterly average temperatures followed estab-
lished summer maximum and winter minimum seasonal patterns with no un-
usual or dissimilar variations. Seasonality in temperature may be im-
portant with respect to seasonal and regional variations in air quality.
For example, a well-defined seasonality in temperature-related pollutants
would more likely be expected in the eastern two-thirds of the nation
where summer and winter temperature differences generally are about
20 degrees greater and where the seasonability in wind speed is more
distinct than in the West. In addition, the seasonality of sulfur dioxide
75
-------
may be related to temperature patterns in the eastern states since the
major sources of this pollutant are linked with the seasonal consump-
tion of fossil fuel.
It would be advantageous to separate the variability due to meteoro-
logy from that due to changes in emissions. While this would be the
ideal approach, it is difficult to quantify the specific contribution
of each component to the overall trend. For long-term air quality
trends, the effect of meteorology may average out because of the
cyclical nature of variation in meteorological variables; however, for
short-term trends the change in air quality from one year to the next
may be influenced by meteorologocal factors. Table 4-1 summarizes the
short-term trends in the three meteorological parameters for the period
1970-1974 and qualitatively relates these to variations in air quality
that might be expected from the effects previously discussed. To relate
meteorological phenomena more quantitatively to air quality parameters,
it is necessary to reduce the spatial scale of analysis because of the
variability that exists on the regional level. As the scale of the
meteorological data base approaches that of air quality, the interpreta-
bility of quantitative relationships would be expected to improve. The
following section, therefore, examines the relationship between air
quality and meteorological data on an SMSA basis.
4.2.2 Effect of Meteorology on Air Quality in Los Angeles: An Example
In order to help identify the effect of emissions on air qualtiy,
it is desirable to remove the effect of meteorology. As an illustration
of meteorological adjustment of air quality levels, a simple model* was
entertained to relate quarterly air quality levels as a linear function
of trend and the selected meteorological variables discussed in section
4.2.1. Because of the complicating influence of seasonality on an analy-
sis using quarterly data, all regression analyses were performed upon
seasonally adjusted measurements. In effect, an examination was made on
departures from typical quarterly values during the 5-year period. A
discussion of the results of this type of analysis for the Los Angeles
SMSA is presented below.
*The model was of the form: P=y + otY + 3^w + 3nT + ^3R' wnere Y represents
year and P, W, T, and R are seasonally adjusted values of pollutant, in-
verse wind speed, temperature, and rainfall, respectively.

In the Los Angeles SMSA, during the period 1970-1974, average wind
speed displayed a consistent downward trend; rainfall remained constant
from 1970 until mid-1972, and then increased through 1974; and tempera-
ture remained fairly constant. These trends are depicted graphically
in Figure 4-4.

Figure 4-4. Comparison of trends in quarterly average temperature, rainfall, and
windspeed in the Los Angeles Basin, 1970 through 1974.
SO2 levels in the Long Beach-Los Angeles SMSA displayed a slight
increase during the period 1970-1975. Composite average concentrations
at nine sites increased from 34 pg/m in 1970 to 37 pg/m in 1974.
Seasonally adjusted levels of SO,, are highly correlated with those of
TSP, suggesting that both pollutant concentrations were affected by
similar influences, whether emissions or meteorology.
Seasonally adjusted average wind speed was found to be significantly
correlated with seasonally adjusted S0_. The decline in average wind
speed may perhaps be partly responsible for the increase in SO,, levels
during this period. Although the characteristic periodicity of quarterly
average temperature corresponded to the average seasonal behavior of
SO0, their seasonally adjusted values were not related. Rainfall was
also not related to variations in S02 levels.

Each of the three meteorological variables was included in the
model. Only inverse wind speed was found to be significant. The ob-
served quarterly levels of SC>2 were normalized to the average meteoro-
logical conditions observed in each calendar quarter. Both before and
after meteorological adjustment, the trend in SO2 was not statistically
significant, but the adjusted values indicate less variation and a
marginal decrease. This comparison is displayed in Figure 4-5.

TIME, year and quarter
Figure 4-5. Comparison of observed and meteorologically adjusted quarter-

through 1974.
The major impact of the meteorological adjustment occurred in the
first quarter of 1972 and generally throughout the latter part of the
5-year period when wind speed averaged slightly below the 24-year normal
of 7.4 miles per hour.
Total suspended particulates in Los Angeles declined moderately
during the 5-year period. Of the three meteorological variables con-
sidered, only rainfall was correlated with TSP. Although the dry season
during the second and third quarters coincided with the period of high
TSP concentrations, seasonally adjusted rainfall was also negatively
correlated with seasonally adjusted TSP- When all three meteorological
parameters were examined jointly in combination with the assumed presence
of a linear trend, the effects of wind speed, and rainfall were found
to be statistically significant. After the effect of these meteorological
parameters was taken into account, the slight downward trend in TSP was
intensified and became statistically significant.
The impact of meteorology can best be viewed by comparing the
observed TSP with TSP levels adjusted to reflect average meteorological
conditions. This is presented in Figure 4-6.
The impact of meteorology on TSP levels was essentially the same
as that on S02 levels. The major downward adjustment came in the
first quarter of 1972, second, third and fourth quarters of 1973,
and during all of 1974, when generally lower wind speeds occurred.

Although it is admittedly highly simplified, the statistical
model employed for this analysis proved to be effective even with
quarterly data. The model did not take into account interdependence
among the various meteorological parameters and was based on composite
measures of air quality and quarterly aggregates of meteorology. Never-
theless, it illustrates the importance of considering the impact of
meteorology on air quality levels and trends.
4.3 AIR QUALITY DATA BASE CHARACTERISTICS
Any presentation of trends in air quality levels requires some dis-
cussion of the data base employed. In this section are given the gen-
eral characteristics of the data base employed in the trends analyses,
as well as the techniques used to summarize this information. As men-
tioned in the national overview, there are considerable differences in
the sizes of the data bases for different pollutants. Reasons for
differences in numbers of monitors range from economic considerations
to improved knowledge of measurement techniques that has revealed some
methods to be imprecise and their historical data consequently unreliable.
Definite differences exist between the data bases employed in
section 3, which deals with status, and this section, section 4, which
deals with trends. While in both cases data obtained from the National
Aerometric Data Bank (NADB) were used in the analyses, different criteria
were used in selecting the data for the analyses, based upon their respec-
tive purposes. The section dealing with status incorporates as many
stations as possible from a given year in order to give a complete
picture of current status with respect to the National Ambient Air
Quality Standards (NAAQS). For trend analyses, however, historical
81
-------
continuity of data is required. Such continuity is needed to ensure
that any apparent trend is actually the result of changes in measured
air quality at a specific location rather than the result of a change
in site location.
The requirement for historical continuity has certain consequences
in terms of the sites that qualify for trend analysis. This is perhaps
best understood by briefly considering the history of air quality
monitoring. Efforts by Federal government to monitor air pollution
have been historically concentrated in the National Air Surveillance
Network (NASN) and the Continuous Air Monitoring Program (CAMP). With
the expansion of non-Federal networks, the NASN and CAMP networks
have been decentralized and are diminishing in scope. Although there
are other Federal monitoring efforts for special study projects , these
two networks have provided, until the last few years, the major
data base for national trends. Although the NASN program at one time
included some 30 background sites, the vast majority of the sites were
in the center-city locations of urbanized areas. The original six CAMP
stations were also located in center-city areas. As would be expected,
the non-Federal monitoring activities are also initially concentrated
in high population areas as individual cities develop their monitoring
networks. In view of this evolution, it is not surprising that the
selection of trend sites based upon historical continuity results in
a sample that is dominated by population-oriented sites in urban areas.
A detailed breakdown of these sites is given in Tables 4-2 and 4-3.
For this particular analysis, the TSP and S0? sites were selected
on the basis of having four consecutive quarters of data in the 1970-
1971 period and four consecutive quarters in the 1972-1974 period.
The restriction on four consecutive quarters was employed to provide
balanced seasonality. The 1970-1971 requirement was used to ensure
that these sites would have data from the early 1970's, which was an
important time period in the implementation of control measures in
many areas. A site was considered to have a quarter of data if it sat-
isfied the SAROAD validity criteria as discussed in section 3. Once
these sites were selected, missing values were computed using linear
interpolation between corresponding quarters of adjacent years. Miss-
ing end points were extrapolated assuming no change from the corres-
ponding quarter of the adjacent year.
While this procedure results in a data base with the same number
of values in each quarter, it is useful to consider whether the results

For comparative purposes/ the general trends obtained by restricting
station selection ("trend" sites) according to the above criteria are
shown in Figure 4-7, along with the trends obtained by using all avail-
able data for this time period. The all-data medians are derived from
TSP data from 4927 sites and S02 data from 2565 sites. For both pol-
lutants the general agreement in the medians from the two data bases
seems reasonable. In each case, the difference in medians is minimal

in the initial year but in the late time periods the trend-site subset
of data is slightly higher than the all-data set. This pattern is con-
sistent with what would be expected as new sites are added in the clean-
er areas. Because problem areas with higher concentrations would more
likely be the first locations monitored, trends based upon an expanding
data base could be influenced merely by the addition of new monitoring
sites in cleaner areas. Therefore, the data set constructed on the
bases of historical continuity has the advantage of adequately describ-
ing the general trends while minimizing the possible effects of a shift-
ing data base.
4.4 REGIONAL TRENDS IN TOTAL SUSPENDED PARTICIPATES
As indicated in the national overview section, a reduction in TSP
levels has been achieved. The purpose of this section is to examine
the data in terms of geographical regions and the specific cities that
dominate the regional trends. Despite the general improvement in TSP
levels, many localities are having difficulty attaining the KAAQS for
TSP. These difficulties fall mainly into two categories: fugitive dust
4
emissions and urban background levels. Fugitive dust refers to TSP
levels that are attributable to factors such as natural sources, tilled
farm lands, unpaved roads, or to activities such as construction. The
fugitive dust problem occurs generally in the western half of the
nation but can also be a contributing factor in the east. The control
of such dust emissions is quite difficult and in some western states it
is estimated that TSP levels resulting from fugitive dust alone are
sufficient to violate the NAAQS. ' The urban background problem
refers to TSP levels in major urban areas that come from numerous mis-
cellaneous sources, such as tire fragments, salt and sand particles
from snow control, or re-entrainment of street dust caused by wind and
traffic flow. These problems are currently under study in many cities,
but it appears that reduction of urban background will require long-
4
term control strategies. These two factors may contribute to the
leveling off observed in the national TSP trends.
The regional trends for TSP are examined by EPA Regions rather
than more general geographical regions. Figure 4-8 shows the geographical
boundaries of the EPA Regions. Table 4-4 shows the SMSAs that contain
at least 10 percent of the total number of trend sites within a region.

As would be expected from the overall improvement shown on the national
level, most of these regions have downward trends in mean TSP levels.
Figure 4-9 categorizes the upward and downward changes during this
period on a regional basis. This is complemented by the graphs in
Figure 4-10, which show the composite average for each region and for
selected SMSAs that are major components of the regional data base and
that had data continuity through 1974. Because of this selection
criterion, it would be expected that the regional trends and the SMSA
trends would be congruent or at least parallel, and, in most cases,
this is true. In Region I, Providence shows a downward trend that is
consistent with the overall regional trend. TSP levels in New York
and Buffalo show more improvement than in Region II overall. In
Region III, the trend in Wilmington, Delaware, is consistent with
the regional improvement. In contrast, Washington, D.C., shows an
upward trend in the late 1973-1974 period. These higher TSP values
in Washington may have been caused by the subway construction activity
in this city. The downward trend in Region IV is linear, while the
trends in Louisville and Nashville are downward but appear to have
occurred more recently. In Cleveland and Chicago, TSP levels decreased,
followed.by a leveling off, which agrees with the overall Region V
trend. Average TSP concentrations in Region VI show a downward trend
as they do in Dallas; while in Houston, TSP levels are fairly stable.
The TSP trend in St. Louis is consistent with the overall improvement
in Region VII.
While TSP levels in Regions I through VII show general improvement,
levels in Regions VIII, IX, and X show mixed and upward trends. Denver
accounts for 30 percent of the sites in Region VIII and is the dominant
factor in the increase in the regional composite average. It has been
suggested that a major contributing factor to the TSP problem in Denver
g
is the sand and salt used for snow control. In Region IX, TSP levels
in San Francisco have been relatively stable in the 1970"s while those
in Los Angeles have shown a slight decrease. Particulate levels in
Los Angeles have remained relatively high despite the implementation
of the usual particulate control strategies, such as reduction of open
4
burning and use of emission controls on major sources. Part of this
difficulty is caused by the formation of secondary particulates from
gaseous precursors that are frequently unaffected by the usual particu-
late control strategies. This is particularly true in the Los Angeles
area, where it has been estimated that approximately 40 percent of the
TSP pollution is caused by these secondary particulates. In Region X,

TSP levels show a mixed pattern, with those in Seattle showing a fairly
stable pattern and those in Tacoma a slight downward trend.
As discussed in section 4.2, rainfall, windspeed, and temperature
were examined for the period 1970 through 1974 for various geographical
regions. These meteorological parameters were used as covariates on
an SMSA basis with the corresponding TSP data to see if the observed
trend could be attributed to these meteorological factors. None of
the trends in TSP levels could be attributed entirely to meteorological
influences. The improvement seen in TSP levels, then, appears to re-
flect genuine progress resulting from reduction in emissions.
4.5 REGIONAL TRENDS IN SULFUR DIOXIDE
The national improvement in average sulfur dioxide levels since
1970 appears to have leveled off in the past 2 years. Despite this
leveling off, S0_ levels in general are much lower than in the late
1960's. A major problem in assessing overall SO,, trends, however,
is the lack of historical data for point sources. As in past years'
reports, less than 5 percent of the sites satisfying the criteria for
selection as a "trend site" were source-oriented.
In Section 5 (Figure 5-6), fuel combustion is shown to be the main
source of SO emissions. Three factors have been identified as having
X
significant impact on current SO2 air quality levels: S02 emissions from
power plants, general availability of clean fuels, and emissions from
4
non-ferrous smelters. The non-ferrous smelters are located primarily
in the western part of the country in AQCRs that are not scheduled to
attain the primary SC? standards until 1977. Because a minimal number
of source-oriented sites have historical data, S09 levels associated
with smelter activity are not adequately reflected in the SO? trends
data base. The two problems of power plant emissions and availability
of clean fuels, although listed separately, are actually interrelated.
An acceptable method for control of SO emissions is the use of cleaner
fuels. Switching to higher-sulfur fuels could necessitate the use of
additional control measures, such as flue-gas desulfurization. There-
fore, at the present time, the availability of clean fuels is a critical
factor affecting trends in ambient S02 levels as well as the control
strategies required to attain and maintain acceptable SO levels.
Table 4-5 and Figure 4-11 display the trends in average SO
levels for 1970 through 1974. Table 4-5 shows the number of sites at

which average S0_ levels increased and decreased between 1970-1971
and 1972-1974. Table 4-6 shows the SMSAs in each region that contri-
buted more than 10 percent of the regional trend data base. Figure
4-11 shows the composite averages for each EPA region and for selected
major SMSAs within each region. In some cases, no SMSA contained more
than 10 percent of the total sites for the region or had more than five
sites; and thus there is no SMSA breakdown. There is general agreement
among the regional and SMSA trends, with the majority of regions showing
improvement. The apparent discrepancy in Region VIII was caused by an
increase at a source-oriented site that affects the eight-site composite
average for this region. As indicated in Table 4-5, several of these
regions have very few sites, so that inferences based on these data
have certain limitations. In Region II, the Rochester and New York
City SMSAs show net declines in S02 levels during the 5-year period,
which is consistent with the regional pattern. The stabilization
occurring in the 1973-1974 period also appears typical. In Region V,
SO levels in Chicago and Cleveland also show net declines. In con-
trast to the general downward trends, both West Coast regions, IX and
X, show increases in SO,, levels; however, these levels were initially
quite low. As in the case of Region VIII, there are very few trend
sites in these regions. The Los Angeles SMSA accounts for 45 percent

of the sites in Region IX, and it shows increasing SO- levels. This
is discussed in more detail later in this section.
Because of the potential impact on S02 levels of the use of
higher-sulfur fuels, it is useful to examine changes between the 1972-
1973 winter and the 1973-1974 winter. This was done on the basis of
quarterly SO- averages for the fourth quarter of 1972 and the first
quarter of 1973 versus the fourth quarter of 1973 and the first quarter
of 1974. In order to utilize data from as many sites as possible, the
general trends criteria were dropped and all sites having data in the
National Aerometric Data Bank for these two winter seasons were used.
This resulted in the use of data from 1922 sites rather than from
just the 258 trends sites. Figure 4-12 summarizes these results for
each EPA Region and for the nation. From these results it appears
that the general improvement in S02 levels seen during the early 1970's
has ended and that the current pattern is quite mixed. Ambient le-s 3ls
of SO- in Regions II and III seem to have experienced a definite re-
versal during this period. This suggests that the energy crisis during
this period may have contributed to increases in SO- levels. Because
of the variety of factors that influence air quality levels, a more
detailed analysis on a case-by-case basis, such as was done in last
year's report, is necessary to establish definitely the exact cause
of this increase. Reports, however, by the New York State Department
of Environmental Conservation and the Philadelphia Department of
Environmental Health indicate that the energy crisis had an adverse
effect in those areas.
Among the possible reasons for present trends in SO- levels,
temperature is an important factor because of the emissions associated
with fuel combustion for heating. As discussed in section 4.2, various
meteorological factors, including temperature, were examined for com-
parisons with air quality trends. Seven out of the ten EPA regions
had warmer winters in the 1972-1974 period than in the 1970-1^71
period. Only Regions VI, VII, and VIII departed from this pattern.
Therefore, a portion of the improvement in SO- levels could be attribut-
able to the warmer winters. All ten regions were warmer in the winter
of 1973-1974 than in the winter of 1972-73. Despite the milder winters,
many sites showed increased SO- levels, which reinforces the possibility
that the energy crisis contributed to the incisase.
As discussed in section 4.2, in only one case did these meteorologi-
cal parameters appear to account for a major portion of the apparent trend.
This occurred in Los Angeles, where"the upward trend in SO- levels coin-
cided with decreasing wind speeds, particularly in the forth quarter

of 1974. At the present time it is anticipated that SO- levels in this
area will increase because of fuel switching associated with natural gas
shortages. This possibility also exists in the San Francisco and San
Diego areas. Consequently, though SO- increases caused by clean-fuel
shortages have been primarily confined to the east so far, such shortages
may also result in SO- increases on the west coast.
In summary, it appears that the general improvement in SO- levels
has leveled off. The current pattern is now mixed, and future trends
will be determined by actual changes in emission levels. This is much
more apparent for SO- than for TSP. Because natural SO- background is
essentially zero for urban areas, ambient SO- levels are much more sen-
sitive to changes in emission levels. This was seen in the decreases
in S02 levels effected by controls in the late 1960s and early 1970s.
It is apparent from recent patterns that future SO- levels will be in-
fluenced primarily by the types of fuels available and the emission
controls associated with fuel combustion.
4.6 REGION-SPECIFIC TRENDS IN CARBON MONOXIDE, OXIDANTS,
HYDROCARBONS, AND NITROGEN DIOXIDE
Carbon monoxide, oxidant, hydrocarbon, and nitrogen dioxide trends
for specific areas of the country will be discussed in this section
because there are insufficient historical data from which to derive
national trends. The specific area analyses are based on data from
the National Aerometric Data Bank (NADB), as well as on summaries of
trends taken from several state and local reports. While separate
trend criteria were used for the NADB, state, and local analyses, in
all cases the data covered a 3-year period at a minimum. The areas ex-
amined include several cities in California, as well as Philadelphia and
the states of New York, New Jersey, and Washington. Historically, Cali-
fornia has had the most extensive monitoring network, and this is reflec-
ted in the trend analyses that follow. In 1970 and 1971 a majority of
the sites that were monitoring oxidant, nitrogen dioxide, and carbon
monoxide in the nation and reporting to the NADB were in that state.
California had 38 out of 45 sites (85 percent) monitoring oxidant, 50
out of 77 sites (65 percent) monitoring nitrogen dioxide, and 28 out of
45 sites (58 percent) monitoring carbon monoxide. In 1974, California
was still dominant, reporting data from 26 percent of all oxidant sites
101
-------
(87 out of 330) to the NADB, from 20 percent of the carbon monoxide
sitee (62 out of 316), and from 8 percent of the nitrogen dioxide
sites (98 out of 1217).
4.6.1 Carbon Monoxide Trends
4.6.1.1 California
Using data from the NADB, carbon monoxide trends are examined
here for the Los Angeles and the San Francisco areas. Table 4-7
indicates that the Los Angeles area has made progress toward meeting
the 8-hour standard inasmuch as the percentage of values above the
8-hour standard has declined; and in the San Francisco area data show
less than 0.5 percent violations of the 8-hour standard. With respect
to the annual second-highest 1-hour average CO concentrations, Los
Angeles has shown some progress, while San Francisco has basically
shown no change.
Carbon monoxide trends are also shown in Figures 4-13 and 4-14
12 13
for San Diego and Sacramento, respectively. The CO levels in
San Diego have been fairly stable between 1963 and 1973, while Sacra-
mento has shown improvement.
4.6.1.2 Philadelphia
14 L4
Based on a report by the Philadelphia Department of Public Health,
carbon monoxide in Philadelphia does not show a clear trend (Figure
4-15) in spite of the use of air pollution control devices on automo-
biles and the achievement of reductions in emissions from stationary
sources. The downward trend over recent months is attributed primarily
to the effects of the 1973-1974 winter fuel shortage and its consequent
reduction in use of automobiles. This trend may also show the early
effects of emission controls on new cars.
4.6.1.3 New Jersey, New York, and Washington
Carbon monoxide trends based on data in the NADB, are summarized
in Table 4-8 for the states of New Jersey, New York, and Washington.

-------
Carbon monoxide levels declined in each of the states as evidenced
by a downward trend in the percentage of annual values greater than
the 8-hour standard. This progress is noteworthy because it is the
8-hour CO standard that is most frequently violated.
There appears to be some progress in reducing the annual second-
highest 1-hour average CO concentrations for New Jersey and New York.
In the state of Washington, the apparent discrepancy between the
downward trend in the percentage of annual values greater than the
8-hour NAAQS and the lack of sustained change in the second-highest
1-hour concentrations is not too surprising. Short-term statistics,
such as the 1-hour maximum, are notoriously influenced by irregular
conditions, such as high CO levels caused by an extraordinary traffic
tie-up. Consequently, the high variability of the 1-hour maximum may
cause it to be an unreliable indicator of real, long-term change;
however, because of its relationship to the NAAQS, its information
content should not be ignored. The percentage of values above a parti-
cular threshold, such as the 8-hour NAAQS, is derived from the average
of an entire year of data, so that CO levels arising from a variety of
conditions have been averaged out; it is, therefore, a more stable
indicator of real change.
The decrease in the percentage of values above the 8-hour NAAQS
seen in Table 4-8 can be explained, in part, by the success of the
Federal Motor Vehicle Emissions Control Program, which has resulted
in reducing CO emissions.
4.6.2 Oxidant and Hydrocarbon Trends in California
California oxidant data from the NADB were examined according
to three groupings: Coastal Los Angeles, Noncoastal Los Angeles, and
the San Francisco Bay Area. In general, oxidant levels found in 1974
from the three groups of California sites confirm a continuation of
the longer-term downward oxidant trends previously reported. '
This improvement can be seen in both the magnitude of the peak hourly
oxidant concentrations (Figure 4-16) as well as in the number of
values exceeding the 1-hour NAAQS (Table 4-9).
Air quality at the group of sites within the Los Angeles area

of decline in concentrations did occur, however, in some areas of the
Los Angeles Basin, as indicated by the trend found at four coastal
sites in Los Angeles in 1973. The California Air Resources Board
attributes the high oxidant concentrations recorded during 1973 to
extranormal meteorological conditions, which emphasizes the poten-
tial impact on air quality of adverse meteorological conditions.
These conditions contributed to the slight increase in the number of
annual violations of the 1-hour NAAQS that occurred within the Los
Angeles Basin during 1973. It is interesting to note that the com-
posite average of the second-highest annual 1-hour oxidant values in
1974 returned to the 1972 low at the four coastal sites.
At the sites selected from the San Francisco Bay area, the second-
highest annual maximum value and the number of values exceeding the
NAAQS have shown improvement. A Bay Area Air Pollution Control District
report, however, indicates that the downward trend in oxidant concen-
18
tration has leveled off somewhat since 1974.
Overall, the general pattern seems to be one of the modest im-
provements in peak oxidant levels and in the frequency with which the
NAAQS are exceeded. The improvements are consistent with scheduled
reductions of hydrocarbon emissions, which are known to cause oxidant
formation.
19
Paskind and Kinosian examined long-term trends in oxidants
and nonmethane hydrocarbons for the South Coast Air Basin of Califor-
nia (Los Angeles) for the period 1963-1973. They found an overall
decrease in emissions and ambient levels of hydrocarbons; and a de-
cline in oxidant concentrations in the western portion of the Basin
and an increase in the eastern portion (Figure 4-17). They concluded
that emissions of hydrocarbons must be further reduced to achieve lower
oxidant concentrations in all areas of the South Coast Air Basin.
Long-term oxidant and hydrocarbon trends at the San Diego site
are shown in Figures 4-18 and 4-19, respectively, for the San Diego
Air Basin for the period 1963-1972. The statistic examined is the annual
average of the daily maximum 1-hour oxidant concentrations. At this
12
station, as at five other stations in San Diego, oxidants decreased
several parts per hundred million (pphm) from the maximum (in 1963) to
12
the minimum year.
The average of maximum 1-hour hydrocarbon concentrations, shown
12
in Figure 4-19, generally remained constant from 1965 to 1973.
Since there was an increase in automobiles and other hydrocarbon
107
-------
sources, this decrease may be attributed to control of hydrocarbon
emissions from automobiles and stationary sources. In California,
motor vehicle crankcase emission control began in 1963 and exhaust
control began with 1966 model-year cars.

4.6.3 Nitrogen Dioxide Trends
4.6.3.1 California
Emissions and ambient levels of oxides of nitrogen show an upward
trend in the South Coast Air Basin (Los Angeles) for the period 1963-
19
1973, according to a paper by Paskind and Kinosian (Figure 4-20).
These authors concluded in their paper that the oxides of nitrogen
emissions must be reduced, along with hydrocarbon emissions, if lower
oxidant concentrations are to be achieved in all areas of the South
Coast Air Basin.
The maximum 1-hour nitrogen dioxide levels in San Diego, shown in
Figure 4^-21, have generally remained unchanged with some random fluc-
12
tuations. Exhaust control systems for hydrocarbon and carbon monoxide
emissions from 1966-1970 model automobiles caused increased emissions
of oxides of nitrogen from these automobiles. Control of oxides of
nitrogen emissions in California began with the 1971 model year.

Philadelphia from 1972 through 1974, possibly reflecting a temporary
increase in nitrogen oxide emissions associated with the 1970-1973
model cars (Figure 4-22), according to a report from the Philadelphia
Department of Public Health. Future reductions in automotive emis-
sions of NO should result in lower N0

4.6.4 Summary
In summary, progress is being made in achieving the NAAQS for
oxidants and carbon monoxide in the Los Angeles Air Basin, the San
Diego Air Basin, the San Francisco Air Basin, and in Sacramento. While
there is no clear trend in carbon monoxide concentrations in Philadelphia,
progress is being made in achieving the 8-hour CO NAAQS in New Jersey
New York, and Washington State.
Hydrocarbon levels are decreasing in the Los Angeles Air Basin
and are unchanged in San Diego. The trend is an increase in NO,,
concentrations in the Los Angeles Air Basin and in Philadelphia, but
relatively no change in San Diego.
As more monitoring stations accumulate at least 3 or more years
of data, long-term air quality trends can be determined for more areas
of the country.

5. SPECIAL TOPICS
5.1 URBAN-RURAL OXIDANT STUDIES
Over the past few years, EPA has been engaged in a program of field
monitoring studies to assess the extent and causes of the high ozone
concentrations (above the NAAQS for photochemical oxidants measured
as ozone) that have been observed in rural areas of the United States,
particularly in the Eastern portion. Because of EPA's interest in
improving the technical basis for oxidant control strategies, the
studies have focused on the contribution to ambient ozone concentrations
of urban ozone precursor emissions and on the relative roles of local
ozone formation and of long-range transport.
A large-scale study was conducted during the summer of 1974 that
covered an extensive area of the Midwest and East. The final report
on the findings and results of the study was published in March 1975.
The study included both ground-based and airborne monitoring of ozone,
ozone precursors, and meteorological variables. Overall direction for
the study was provided by the Monitoring and Data Analysis Division
(MDAD) of OAQPS. Major contributions to the study were made by the
Research Triangle Institute (RTI), the principal MDAD contractor; and
by the Chemistry and Physics Laboratory, NERC-RTP, and its contractors.
Sampling was performed from June 15 through August 31, 1974. The area
covered by the ground monitoring network is shown in Figure 5-1.
Table 5-1 presents data on maximum hourly ozone concentrations observed
and frequency of occurrence of concentrations above the NAAQS of 0.08
ppm (160 micrograms/cubic meter). It should be noted that at DuBois,
a small town in rural Pennsylvania, the oxidant standard was exceeded
for 341 hours during the measurement period. During the same period,
Pittsburgh, approximately 100 miles southwest of the station, had only
106 hours during which the standard level was exceeded. The maximum
hourly concentration at DuBois was 0.20 ppm; at Pittsburgh, it was
0.14 ppm. Oxidant levels in urban areas may I -j suppressed by reactions
of ozone with nitric oxide, a product of automotive exhaust. Oxidant

Recent measurements downwind of urban centers (Houston, Phoenix,
several Ohio cities, and Philadelphia) ' demonstrate that an identi-
fiable urban plume of oxidants and oxidant precursors can be found as
far as 30 to 50 miles from the urban center. In Los Angeles, where the
magnitude of oxidant generation is greater, the distance extends perhaps
75 miles or more downwind. Beyond these distances, the contribution

of pollutants (from one city) becomes so well mixed with other urban and
nonurban contributions that the individual urban effect is difficult to
distinguish.
Data collected in the 1974 EPA oxidant study have been correlated
with meteorological parameters. The data analysis suggests that beyond
the shorter range of 50 to 75 miles, pollutants become rather well mixed
in the prevailing pressure systems. High-pressure systems have been
found to be associated with the highest ozone concentrations. A re-
lationship between average ozone concentrations for the eastern midwest,
using 1973 study data, and average pressure for the area (with a 9-day
smoothing function applied) is shown in Figure 5-2. The central
portions of high-pressure systems in the mideastern portion of the

country have been found usually to contain the highest rural ozone
concentrations. Areas within .central portions of high-pressure
systems are often favored for light winds, high solar intensity, and
higher temperatures. Therefore, the conditions associated with central
portions of high-pressure systems are considered more important than
the existence of high pressure itself. A sequence of 2 days of data
showing ozone, weather, and emission density values during the passage
of a high-pressure weather system during the 1974 Midwest Study is

The following briefly summarizes the findings and conclusions of
the 1974 summer oxidant study.
1. Both maximum concentrations of photochemical oxidants and
the frequency with which the standard was exceeded were generally
higher at rural than at urban sites. The NAAQS was exceeded approxi-
mately twice as frequently at the rural stations. Mean diurnal ozone
concentration curves for the rural and urban stations were similar,
varying mainly in magnitude of hourly ozone concentration and time of
120
-------
maxima. Nocturnal concentrations of ozone were, on the average, three
to five times higher at the rural sites relative to the urban sites.
2. Nitrogen dioxide concentrations observed at the rural stations
were consistently at or near the minimum detectable level for the measure-
ment method (i.e., approximately lOyg/m ).
3. There were periods (at times 5 days or more) during which
the surface and near surface concentrations of ozone measured by air-
craft equaled or exceeded the standard of 160yg/m (0.08 ppm) hourly
average over large areas (2.3 x 10 square kilometers or more). That
the air contained anthropogenic air pollutants was demonstrated by the
presence of acetylene in all hydrocarbon samples and the presence in a
preponderance of samples of carbon monoxide in concentrations two to
six times the usually quoted geochemical background of 91 to 137yg/m
(0.08 to 0.12 ppm).
4. An area-wide system I with a radius of 240 kilometers (150 miles)
or more] of high ozone concentrations can exist in which most features
that suggest precursor origin are no longer apparent; but a short-range
urban influence on both hydrocarbon and ozone concentrations can be
observed. The data showed a discernible urban influence extending
about 48 to 80 kilometers (30 to 50 miles) downwind of a city.
5. When the central region of a synoptic high-pressure system^a
region characterized by relatively clear skies and weak, disorganized
flow near the surfacemoved into the area being studied, high concen-
trations of ozone generally occurred at all stations. In this context,
high concentrations of ozone are defined as levels in excess of 160 ug/m
for 8 hours each day. This condition persisted as long as the high-
pressure center remained in the immediate vicinity.
6. Pertinent data from the 1974 summer study show that the high
concentrations of ozone observed at rural sites were generated in the
lower troposphere.
7. The observed high ozone concentrations cannot be explained in
terms of air flow from a specific point source or from a single urban-
industrial area source.
8. The results of this investigation provide substantial evidence
for the transport of ozone precursors from urban to rural areas under
appropriate meteorological conditions. During transport in the presence
of sunlight, ozone is synthesized.
121
-------
9. The results of this investigation indicate that the control
of hydrocarbon emissions in any individual city will reduce but will not
necessarily prevent the occurrence of high rural ozone concentrations
in excess of the ambient air standard at any given rural site. The in-
dication is that the release of hydrocarbons and oxides of nitrogen from
anthropogenic or biogenic sources, located in either an urban or rural
area, all combine to generate appreciable quantities of ozone over wide
areas.
Additional large-scale field studies took place during the summer
of 1975. These studies attempted to answer relevant questions not
previously resolved by field studies or research. The two studies were
conducted concurrently: one from the Upper Great Plains eastward to the
Appalachians, and the other along the Western Gulf Coast (between Corpus
Christi, Little Rock, and Mobile). Ground and airborne sampling were
included in these studies. The main purpose of the Great Plains Study
was to follow the development of high ozone concentrations in high-
pressure systems as they entered "clean" from areas of origin in
West-Central Canada into the United States and moved eastward. The
analysis is incomplete, but concerted efforts are being made to assess
the relative contributions of natural and man-made sources to the
development of high oxidant concentrations. The Gulf Coast Study was
mainly exploratory, its main purpose being to examine the distribution
and probable causes of ozone concentrations over a wide area characterized
by the presence of large petrochemical sources. Few monitoring data
have heretofore been available for areas surrounding major cities in
the Gulf Coast area in which some of the highest ambient oxidant values
outside of Los Angeles have been observed. Figure 5-5 shows a map of
the general areas covered by the two 1975 studies and the locations
that have been selected for ground-based monitoring. Airborne moni-
toring off-shore and inland were included to assess the role of large-
scale as opposed to smaller-scale circulation of air (such as the sea
breeze), and thus distant versus local generation of the ozone that
contributes to locally observed ozone levels.
Another regional-scale oxidant study was also conducted in the
southeastern New England area during the summer of 1975. Its purpose
was to assess the factors contributing to high concentration levels
in the corridor dominated by New York City and Boston. Results for
this study as for the other two large-scale studies are expected by
mid-1976.

5.2 NATIONWIDE EMISSION ESTIMATES
These estimates of nationwide emissions for 1970 through 1974
compris newly calculated, internally consistent sets of figures based
on the most current emission factors and on a more inclusive list of
source categories than previously used. Consequently, the emission
estimates presented here supercede any previously published estimates
for the years since 1970. Obviously.- previously published estimates of
emissions for years prior to 1970 will also lack strict continuity with
these figures for the 1970 through 1974 period.
Appendix Tables F-l through F-5 list the estimates of yearly total
emissions for 1970 through 1974, respectively, for particulates (Part),
sulfur oxides .(SO ) , nitrogen oxides (NO ) , hydrocarbons (KG) , and carbon
X X
monoxide (CO). Sources of these pollutants are divided into the major
categories and several subcategories responsible for significant con-
tributions to the national totals.
Two distinctions between these emission estimates and ambient
pollutant measurements should be noted. First, the emission estimates
for particulates, sulfur oxides, and nitrogen oxides embrace a broader
range of substances than are measured by routine ambient air monitoring
equipment. The high-volume air sampler collects only the particulates
suspended in air that range from approximately 0.3 to 100 micrometers
in diameter, while emission inventories include all man-made particulates,
suspended and settled. Sulfur dioxide and nitrogen dioxide ambient
air monitors measure only those two specific compounds, not all the
oxides of sulfur and nitrogen included in the emission estimates.
In each case, however, the compound actually measured is the most
prevalent constituent of its pollutant class or is acknowledged to be
its most representative indicator.
Second, the tables of estimated emissions include hydrocarbons
but not oxidants, and the tables of ambient data include oxidants
but not hydrocarbons. Obviously, oxidant emissions would not be
meaningful because the overwhelming majority of oxidants are so-called
secondary pollutants generated by photochemical reactions in the at-
mosphere. Emissions of hydrocarbons are important because hydrocarbons
are a major ingredient for those oxidant-producing reactions; yet
ambient measurements of hydrocarbons are not reported because a reliable
method has not yet been developed for the continuous monitoring of
this large and diverse class of compounds. Consequently, monitoring
is not required.

been declining rather steadily, a decline mainly attributable to emis-
sion controls and process changes in two emission categories, stationary-
source fuel combustion and industrial processes. AS a consequence,
a significant number of monitoring stations have reported decreases
in average levels of total suspended particulates (see section 4).
Total emissions of sulfur oxides are estimated to have declined
slightly. Monitoring results show that ambient levels in the relatively
well-monitored urban areas have declined markedly in recent years (see
section 4), which suggests a significant shift in the use of higher-
sulfur fuels by urban sources to their use by a growing number of
sources in relatively sparsely monitored areas. It has also been
1
estimated that SO emissions from electric-power-generating plants in-
X
creased through at least 1973. These plants contribute some 70 percent
of the SO emissions in the stationary-source category.
X
Nitrogen oxide emissions are up slightly, primarily in the trans-
portation category. This can be attributed in part to growth in the
number of vehicular and stationary sources and in part to a slight
increase in NO emissions from the 1968 through 1972 model-year vehicles
X
as a consequence of modification designed to reduce CO and hydrocarbons.
Hydrocarbon emissions have decreased slightly in the transportation
and solid-waste-disposal categories. The decrease in the transportation
category takes on more significance if one remembers that the vehicle
population was still increasing at a fairly steady rate through 1974.
(The installation of closed systems for handling volatile liquids and
the addition of controls on evaporative gasoline losses from automobiles
are examples of actions that will both reduce emissions and conserve
resources.)
Carbon monoxide emissions show the most dramatic decrease, prin-
cipally in the transportation category, and, again, in spite of a
rising number of vehicles.
In addition to the trends shown in Figure 5-6, a prominent feature
of the graphs is the relative contribution from the five source categories
The transportation category (A) dominates CO emissions and contributes
a substantial portion of the NO and HC emissions; transportation is a
X
minor contributor, however, to particulate and SO emissions. The
X
stationary sources group (B) contributes a significant portion to the
totals for particulates, SO , and NO ; but a minor portion to the HC
X X
and CO totals. Industrial processes (C) are the major source of
particulates, contributing smaller yet significant percentages to SO
X
126
-------
and CO totals. Solid waste disposal (D) only really shows up as a
source of CO. The miscellaneous category (E) is significant only for
its tic and CO emissions.

APPENDIX A.
SUSPENDED PARTICULATE MATTER
At present, only one method is generally accepted for the
measurement of suspended particulate matter (the reference
method); that is, the gravimetric determination of the net weight
of material collected on a 20- by 25-centimeter 8- by 10-inch)
glass fiber filter through which approximately 2200 cubic meters of
air have been drawn over a 24-hour period. The high-volume
sampler used to collect such samples is familiarly known as a
high-vol.
In Table A-l, the hi-vol stations are listed by AQCR. Stations in
interstate AQCRs are sorted according to their respective states.
The body of the table (refer to Figure A-l) contains a line for each
reporting station, starting with the state name, site code, station
name, and year - 1974. The next three columns show the number of
valid values reported, and the number of those values exceeding the
secondary (150 yg/m ) and primary (260 yg/m ) 24-hour standards. The
next two columns list the first- and second-highest values, in micro-
grams per cubic meter. From these values, one can judge either the
degree to which the 24-hour standard has been exceeded or the margin
by which it has been met.
The final three columns pertain to the annual geometric mean,
showing its ratio to the secondary (60 yg/m ) and primary (75 yg/m )
annual standards and the annual geometric mean-itself, if four valid
quarters of data have been reported. If only two or three valid
quarters have been reported, a tentative annual mean is shown, followed
by a question mark. Because these tentative means are not used in ap-
praising standards, no ratios are given.
Stations appearing in this listing, but showing no entries in
the last three columns have reported at least three samples for the
year, but fewer than two valid quarters of data.

APPENDIX B.
SULFUR DIOXIDE
Data from 24-hour bubbler monitors, the reference method,
and from continuous SC»2 monitors are summarized in Table B
(refer to Figure B-l) . The right-hand column identifies
the instrumental method used at each station. All of the
continuous instrumental methods are candidate methods pend-
ing. (Federal approval.
Stations are grouped by AQCR in Table B-l. Stations
in interstate AQCRs are grouped according to their respec-
tive states. In the body of the table, each line represents
a station, beginning with its state, station code, station
name and year - 1974. The next column, number of valid
values, represents the number of 24-hour samples for
bubblers or hourly measurements for continuous instruments.
The next column reports the number of values (or 24-hour
averages, midnight to midnight, for continuous instruments)
exceeding the 24-hour standard (365 ug/m ) . The first- and
second-highest 24-hour values (or averages) are reported
in the next two columns .
The next column pertains only to continuous instruments,
reporting the number of times the running 3-hour average
of the hourly SO measurements exceeded the 3-hour standard
(1300
The remaining two columns present the ratio of the
annual arithmetic mean to the annual standard (80 ;ug/m )
and the annual arithmetic mean itself, if four valid
quarters have been reported. If only two or three valid
quarters have been reported, a tentative annual mean is
shown, followed by a question mark. Because these tentative
means are not used in appraising standards, so no ratios are
given.
Stations appearing in these tables , but showing no entries
in the annual summary columns, have reported at least three
bubbler values or 400 hourly values, but fewer than two valid
quarters of data.

Valid annual means are based on 4 valid quarters; " ">. " indicates a tentative mean based on 2 or 3 valid quartan.
Ratio to annual standard (80 p. g/m3) is shown only if annual mean is valid.
Number of 3-hour running average values exceeding the 3-hour standard (1300 /j g/m3). Applies to continuous instruments
only.
Two highest 24-hour concentrations (midnight-to-midnight average for continuous monitors); " #

Number of 24-hour values exceeding the 24-hour standard (365 /j g/m3). Midnight-to-midnight averages used for continuous
monitors.
Number of 24-hour bubbler samples (365 possible), or number of hourly values from continuous monitors (8760 pouibli).
All data in this table are for 1 974.
Following each AQCR number and name is a line for each station reporting in the AQCR showing
number, and the city or county in which ft is located.

APPENDIX C.
CARBON MONOXIDE
Stations are grouped by AQCR in Table C-l. Stations in interstate
AQCRs are grouped according to their respective states. In the body
of the table (refer to Figure C-l), each line represents a station, show-
ing its state, station code, station name, and year - 1974. The next
two columns list the number of valid hourly values reported and the
number of those values exceeding the 1-hour standard (40 mg/m ). The
next column reports the number of times the moving 8-hour average exceeded
the 8-hour standard (10 mg/m ).
The next column lists the 99th percentile in the frequency distri-
bution of 1-hour values; that is, the concentration that 99 percent
of the values are equal to or less than. This statistic gives perspec-
tive on the upper range of values in addition to the first- and second-
highest 1-hour values shown in the next two columns.
The next two columns show the first and second highest moving
8-hour averages (the second-highest value is from a different day than
the maximum value).
The final column lists annual means, if 75 percent of the possible
hourly values for four quarters have been reported. A tentative annual
mean, followed by a question mark, is shown if only two or three valid
quarters of data have been reported. Stations showing no annual statis-
tics reported at least 400 hourly values but fewer than two valid quarters
of data.

All data in this table are for 1974.
Following each AQCR number and name rs a line for each reporting station in the AQCR showing rts stata, the srt« codi
number, and the city or country in which it is located.
No method column; NDIR -11 is reference method and flame ionization - 21* is candidate for equivalent method (values
tagged with * in table were determined by flame ionization - 21).

APPENDIX D.
OXIDANT/OZONE
Table D-l presents results obtained from five different methods, only
one of which - chemiluminescence, No. 44201 11 - is the reference method.
The remaining methods are candidates for equivalency to the reference
method.
Stations are listed by AQCR. Stations in interstate AQCRs are
sorted according to their respective states.
The body of the table (refer to Figure D-l) contains a line for each
reporting station, starting with the state name, the station code, the
station name, and the year - 1974. The next two columns list the number
of valid 1-hour standard (160 yg/m ). The next two columns list the
.first- and second-highest 1-hour values, giving a measure of the degree
to which the standard has been exceeded or the margin by which it has
been met. The next columns, 99th percentile, gives an additional
measure of the upper range of concentrations.
The final column identifies the instrumental methods used at each
station by code numbers, which are elaborated in the table heading
Stations appearing in this listing have reported at least 400 hourly
values.

Method codes are identified in the heading; 44201 is the Federal Reference Method.

APPENDIX E.
NITROGEN DIOXIDE
At this writing, there is no approved reference method
for the measurement of nitrogen dioxide. Eight candidate
methods are reported in Table E.
The NC>2 monitoring stations are listed by AQCR j n Table
E-l. The body of the table (refer to Figure E-l) contains a
line for each station reporting at least three bubbler values
or 400 hourly values. Each line contains the state name,
station code, station name, and the year1974. The next
column records the number of valid values reported. For
24-hour methods, the reported values will be small--usually
less than 60. For continuous methods, the number of 1-hour
values will be 400 or more.
The next column lists the highest 24-hour value or
24-hour average (based on bubbler or continuous instrument,
respectively).
The next two columns show the ratio of the annual mean
to the annual mean standard (100 yg/m3) and the annual arith-
metic mean itself if four valid quarters of data have been
reported. If only two or three valid quarters have been
reported, a tentative annual mean is shown, followed by a
question mark. These tentative means are not used in
appraising standards; so no ratios are given.

16. ABSTRACT
This report presents a comprehensive tabulation of the nation's air quality and
monitoring activities for 1974. These summaries are based on data acquired through
extensive monitoring activities conducted by Federal, state and local air pollution
control agencies, and compiled according to the nation's 247 Air Quality Control
Regions. Information is provided on the five pollutants for which National Ambient
Air Quality Standards have been set (suspended particulate matter, sulfur dioxide,
carbon monoxide, oxidants, and nitrogen dioxide). Analyses of pollutant trends
are presented for the period 1970-1974, plus a discussion of nonurban ozone and
estimates of nationwide emissions for the period 1970-1974.
