Introduction
The Clean Air Act (Act) requires periodic review and, if
appropriate, revision of the national ambient air quality
standards (NAAQS) and of the air quality criteria on which they
are based. The Environmental Protection Agency (EPA) completed
its last formal review of the air quality criteria for ozone in
1989. Based on that review, on March 9, 1993, the EPA published
a decision to not revise the current ozone standards (58 FR
13008) .
However, since 1989, a substantial number of new studies
have been published on the health and environmental effects of
ozone. Based on this significant new research, the EPA has begun
another formal review of the ozone standards. (Attachment D is
the Federal Register notice announcing this review.)
Based on an initial assessment of the scientific literature
and the need to plan and conduct analyses in support of the NAAQS
review, EPA staff developed a range of alternative ozone standards
for potential consideration. These standards, summarized in the
"Background" section, were identified in the ozone NAAQS
Development Plan that was given to the Clean Air Scientific
Advisory Committee (CASAC1) in December 1993.
The purpose of this document is to provide the public with air
quality information which will enhance its understanding of the
various alternative NAAQS currently under consideration.
For further information concerning air quality data or the
NAAQS review process, the user should contact his or her
appropriate EPA Regional Office. Attachment C is a list of
Regional contacts and their phone numbers.
'The Clean Air Scientific Advisory Committee (CASAC) is a
committee of independent scientific experts established under the
Clean Air Act to provide review and advice on NAAQS reviews and
on the scientific criteria upon which the NAAQS are based.
-------
Overview
As required by the Clean Air Act, EPA is undertaking a
review of the national ambient air quality standards (NAAQS)
for ground-level ozone (smog). Since EPA's last Ozone
Criteria Document update occurred in 1989, a substantial
number of new studies have been published.
Currently, both the primary (health) and secondary (welfare)
ozone standards are set at .12 parts per million (ppra),
[daily maximum, 1-hour average, with 1 expected exceedance
allowed per year]. The primary standard is set to protect
for acute health effects; the secondary standard for effects
on crops, ecosystems, and materials.
The EPA is currently considering a number of alternatives
for both the primary and secondary standards including
different levels and different averaging times. (See table
of alternatives on "Background" page.)
The EPA will not make a final decision on whether or how to
revise the ozone standards until the Agency's Ozone Criteria
Document has gone through an extensive peer review and
public comment period. The EPA anticipates issuing a
proposed decision in mid-1996 and the final decision in mid-
1997.
As part of the review process, EPA has prepared air quality
maps for each alternative currently under consideration.
These maps are meant only to provide an indication of the
number of people living in counties with monitors measuring
ozone concentrations within a specified range.
These maps do not represent current or potential ozone
nonattainment areas. They reflect air quality data taken
from counties with ozone monitors and are used only to
illustrate areas with ozone readings (1987-1992 monitored
data) that would exceed each alternative presently under
consideration .
During the standards review process, EPA intends to continue
vigorously to pursue implementation of the current ozone
standards. Assessments indicate that control strategies to
attain the current standards will continue to be needed
under any of the alternative standards presently under
consideration.
Several supporting materials accompany these maps. Their
purpose is to aid the public in interpreting the maps and to
enhance the public's understanding of the NAAQS review
process.
-------
BACKGROUND
A. The Alternative NAAQS Presently Under Consideration
The primary NAAQS is designed to protect public health. The
secondary NAAQS addresses ozone effects on public welfare,
including damage to crops, trees and other vegetation,
ecosystems, and materials.
Currently, the primary (health) and secondary (welfare)
ozone standard levels are identical at .12 parts per million
(ppm). They are both 1-hour (average) standards and are attained
when the expected number of days per calendar year with maximum
hourly average concentrations above .12 pm is equal to or less
than 1.
The alternative standards presently under consideration are:

Note: A combination is also possible. For example, one possibility is for
the EPA to propose keeping the current primary standard and adding a second
primary standard to it.
As part of the standards review process, EPA has prepared an
air quality map for each alternative presently under
consideration. The air quality data used for these maps was
1987-1992 data collected from the existing national network of
ozone monitors. These data are stored on EPA's national air
quality database called the Aerometric Information Retrieval
System (AIRS). Attachment A provides a detailed explanation of
how the ozone design values used for the maps were calculated.
Following review, if the EPA determines that a revision of
the ozone standards is warranted, the target date for proposal of
the revised standard(s) is mid-1996. Promulgation is projected
for mid-1997 (see Attachment D).
-------
B. How the Maps Were Developed and What They Mean
These maps reflect air quality data taken from counties with
ozone monitors. The maps show design value concentrations. For
this exercise, the design values varied depending on which and
how many years were considered for the attainment test and on the
averaging time applied.
The key at the bottom of each map indicates the
concentration range for each county. The scale to the left of
each map indicates the number of people living in counties which
have design value concentrations within the corresponding range.
These maps do not represent ozone nonattainment areas and do
not match the current list of ozone nonattainment areas. Their
only purpose is to illustrate counties with ozone monitors
relative to a particular concentration range and relative to a
particular averaging time. White areas on the maps are those
areas for which the EPA has insufficient or no air quality data
1987-92.
Presently, there are 94 classified ozone nonattainment
areas.
The most recent national list of ozone nonattainment areas is
contained in 40 CFR1 Part 81.301. The only way for a
nonattainment area to be redesignated to attainment is to meet
EPA's redesignation policy and the requirements in section
107(d)(e)(i-v) of the 1990 Amendments.
For the secondary standard the EPA is reviewing several
SUMOX alternatives. The SUMOX values are calculated by summing
all of the hourly ozone concentrations at or above a specified
concentration measured during the maximum (consecutive) 3-month
period of the year.
C. Implementation
The 1990 Amendments revamped the requirements for areas that
had not attained the national ambient air quality standards
(NAAQS). Ozone nonattainment areas in particular were subject to
a host of new requirements in order to meet the NAAQS. The Act
set up a classification scheme which imposed additional and more
stringent controls based on the severity of the ozone problem.
To date, States have had to adopt and implement a myriad of
control measure requirements as mandated by the Act.
'"CFR11 stands for Code of Federal Regulations. The CFR is a
codification of all the Federal rules published in the Federal
Register, a daily U.S. Government publication. The CFR is
available at most public libraries and is updated every July.
-------
Control measures approved into the State implementation
plans (SIP's) have brought a number of lower classified areas
into attainment. Additionally, the other higher classified areas
with future attainment dates have shown lower ozone air quality
levels, which can be attributed to implementation of controls.
Depending on an area's classification, States will still have to
implement additional SIP measures to reach attainment.
Consequently, it is important to continue implementation of the
current program to attain the .12 ppm 1-hour NAAQS.
Nevertheless, the question arises as to whether these efforts to
meet the current standard would be appropriate for meeting a
potentially more stringent standard with a longer averaging time.
Recent EPA analyses show that emission control measures
implemented by States to reduce volatile organic compound (VOC)
and nitrogen oxides (NOx) reduce both 1-hour and 8-hour ozone
concentrations. Preliminary photochemical modeling analyses
using the Regional Oxidant Model looked at the effect of the
current ozone control program mandated by the Act coupled with
additional VOC and NOx reductions on peak 1-hour and 8-hour ozone
concentrations in three ozone nonattainment areas. The modeling
further shows that controlling VOC and NOx emissions for both 1-
hour and 8-hour average ozone levels does not change the spatial
distribution of the maximum concentrations.
The EPA believes these preliminary results suggest that the
current NAAQS control programs would still be needed to address
an 8-hour peak standard, if one is promulgated by EPA. During
the ozone standards review process, the EPA will continue
implementing the current control program designed to meet the
current standards and the requirements of the 1990 Amendments.
If the ozone NAAQS are revised, States will be apprised of any
changes through the NAAQS review process.

MEMORANDUM
SUBJECT: Ozone and Carbon Monoxide Design Value Calculations
FROM: William G. Laxton, Director
Technical Support Division (MD-14)
TO: See Below
In discussions related to the Clean Air Act legislation, design
values for ozone and carbon monoxide are receiving particular
attention. Previously, it sufficed to designate areas as either
attainment or nonattainment but now areas will be further classified
into different categories based upon the magnitude of the appropriate
design value. This additional classification step places added
emphasis on the need to accurately determine these design values. The
classification will be done according to concentration cutpoints, and
on a schedule, specified in the legislation.
Obviously, once this process is set in motion we will be working
very closely with you to develop these design values. However, I
thought it would be appropriate to reiterate our design value
computation procedures in advance to help people anticipate the types
of data review questions that may arise. The computation procedures
stated here are consistent with our previous methods. There are
differences between the procedures for ozone and carbon monoxide
because the ozone National Ambient Air Quality Standard (NAAQS) is
structured in terms of expected exceedances while the carbon monoxide
NAAQS uses the older "once per year" format. The most apparent
difference is that the CO design values are based upon 2 years of data
while design values for ozone use 3 years. Another difference is that
the ozone NAAQS uses the daily maximum ozone value while the CO NAAQS
considers running 8-hour averages so that, even though they must be
non-overlapping, it is possible to have more than one CO exceedance per
day. Because of these differences, it is convenient to discuss each
pollutant separately. With respect to terminology, you may hear the CO
design value approach referred to as "the highest of the second highs',
while the ozone design value is frequently simplified as "the fourth
high in 3 years."
One point to remember is that all locations within an area have to
meet the standard (NAAQS). Therefore, when we do our evaluations, we
look at each individual site to make sure that every site meets the
standard. A separate design value is developed for each site that does
not meet the NAAQS, and the highest of these design values is the
design value for the area.
-------
Carbon Monoxide
CO design values are discussed in terms of the 8-hour CO NAAQS,
rather that the 1-hour NAAQS, because the 8-hour NAAQS is typically the
standard of concern. However, a 1-hour design value would be computed
in the same manner. For 8-hour CO, we simply look at the maximum and
second maximum (non-overlapping) 8-hour values at a site for the most
recent 2 years of data. These values may be readily found on an AIRS
AMP450, "Quick Look", printout. Then we choose the highest of the
second highs and use this as our design value for that site. We then
look at all design values within an area and the highest of these
serves as the design value for the area. Note that, for each site,
individual years of CO data are considered separately to determine the
second maximum for each year - CO data are not combined from different
years. It is probably worth commenting on this. The CO NAAQS requires
that not more than one 8-hour average per year can exceed 9 ppm
(greater than or equal to 9.5 ppm to adjust for rounding). We evaluate
attainment over a 2-year period. If an area has a design value greater
that 9 ppm, it means there was a monitoring site where the second
highest (non-overlapping) 8-hour average was greater that 9 ppm in at
least 1 year. Therefore, there were at least two values above the
standard during 1 year at that site and thus the standard was not met.
Hypothetical Case (two CO sites in an area)
(8-Hour Averages)
MAX 2nd High
SITE 1 1987 14.6 8.9
1988 13.9 10.9
10.9 is the Design Value
for Site 1
(8-Hour Averages)
MAX 2nd High
SITE 2 1987 12.2 11.1
1988 10.8 10.4
11.1 is the Design Value
for Site 2
11.1 ppm would be the design value for the area.
Ozone
The form of the ozone NAAQS requires the use of a 3-year period to
determine the average number of exceedances per year. In its simplest
form, the ozone standard requires that the average number of
exceedances over a 3-year period, cannot be greater than 1.0. An area
with four exceedances during a 3-year period, therefore, does not meet
the ozone standard because four exceedances in 3 years averages out to
more than once per year. Now, if the fourth highest value was equal to
the level of the ozone standard, i.e. 0.12 ppm, then the area would
have no more than three exceedances during the 3-year period and the
average number of exceedances per year would not be greater
-------
than one. This assumes no missing data and is how the fourth high
value in 3-years came to be used as the design value. Actually, an
adjustment is specified in the ozone NAAQS to account for missing data
in determining the expected exceedances for ozone. Because of
considerations associated with control strategy modeling, the following
basic approach for ozone design values has been in use since 1981. If
there are 3 complete years of ozone data, then the fourth highest daily
maximum during the 3-year period is the data, then the fourth highest
daily maximum during the 3-year period is the design value for that
site. If only 2 complete years of data are available, then the third
highest is used and, if only one complete year is available, then the
second highest is used. In this approach, a year of ozone data is
considered complete if valid daily maximums are available for at least
75 percent of the ozone season. Note that because of the form of the
ozone NAAQS, data are combined over multiple years but they are not
combined from different sites.
Hypothetical Case (two O3 sites in an area, each year at
least 75% complete)
FOUR HIGHEST DAILY MAXIMUM VALUES
Max 2nd Hi 3rd Hi 4th Hi
SITE 1 1986 .127 .123 .122 .110
1987 .129 .124 .121 .116
1988 .142 .136 .134 .115
The design value for Site 1 is 0.129 ppm, the fourth highest
daily maximum value during the three year period.
FOUR HIGHEST DAILY MAXIMUM VALUES
Max 2nd Hi 3rd Hi 4th Hi
SITE 2 1986 .110 .100 .095 .090
1987 .110 .100 .095 .090
1988 .180 .175 .160 .110
The design value for Site 2 is 0.110, the fourth highest
value during the three year period.
0.129 ppm would be the design value for the area.
There are a few additional comments warranted on the ozone
example. First, note that data from each site was treated
independently in computing the design value for that site. Assuming no
missing data, the second site would meet the ozone NAAQS but the area
would not because the other site shows that the NAAQS is not being met.
Also, it should be noted that the high
-------
values for a year are considered even if the data for that year did not
satisfy the 75 percent data completeness criterion. For example, if a
site had 2 years of data that met the 75 percent data completeness
requirement and 1 year that did not, then the third highest value
during the 3-year period would be the design value because there were
only 2 complete years of data but the data from all 3 years would be
considered when determining the third highest value. This ensures that
valid high ozone measurements in a particular year are not ignored
simply because other data in that year were missing. When computing
data completeness, the number of valid days can be increased to include
days that may be assumed to be less than the standard level as stated
in the ozone NAAQS. Also, for new sites that have just come on line,
the 75 percent data completeness requirement for the start-up year may
be applied beginning with the first day of actual monitoring as long as
the data set is at least 75 percent complete for June through August.
A final practical complication that must be addressed in
determining ozone design values is the case where a site reports data
but has no year that meets the 75 percent data completeness
requirement. Admittedly, this is an unusual situation but, for the
sake of completeness, it needs to be addressed. At the same time,
however, the reason for this consistent data completeness problem
should be examined because ozone monitoring data completeness is
typically greater that 90 percent. In general, if a site has no
complete years of data and fewer than 90 days of data during the 3-year
period, the design value will be determined on a case by case basis.
In such cases, the data base is so sparse that it would be extremely
difficult to describe general rules that would apply and a careful
evaluation would have to be made to determine why this situation
occurred and what is the most appropriate way to use the data. For a
site without a single complete year of data but at least 90 days of
data during the 3-year period, the following steps are followed in
determining the ozone design value:
1. Divide the number of valid daily maximums during the 3-year
period by the required number of monitoring days per year.
As noted earlier, the number of valid days can be increased
by including the number of days that may be assumed to be
less than the standard level as specified in the ozone NAAQS.
2. Add 1.0 to the above total and then use the integer portion
of the result as the rank of the design value.
These steps are not as complicated as they may initially appear.
For example, suppose a site with a required ozone monitoring season of
214 days each year reports 0, 121, and 130 valid days of ozone data
during the 3-year period. Step 1 would give (0+121+130)/214=1.17. In
step 2, 1.0 is added to this total giving 2.17. The integer portion of
2.17 is 2 and so the design value is the second highest value during
the three year period. Again, this type of situation should not occur
that often and the reasons for the data completeness problems should be
identified.
When discussing data completeness for ozone, it is important to
recognize that monitoring sites are occasionally discontinued for valid
-------
practical reasons. In such cases, if data are available from another
site that is representative of the same situation, then data from the
discontinued site may be superceded by data from the other site. The
intent is to ensure that a single year of data from a monitor that was
discontinued 2 years ago, does not dictate the design value if data are
available from another, equally representative, site. This is not
intended to eliminate the missing data penalty when a site is
discontinued and there is no data available from a similar monitor.
I have not discussed certain basic data handling
conventions, such as computing 8-hour CO averages with missing
data, determining the non-overlapping second maximum 8-hour
average, or the definition of a valid daily maximum 1-hour ozone
daily maximum. All of these conventions have been in place since
the 1970's and are routinely incorporated into AIRS outputs so I
have not bothered to discuss these points.

Supplement. The notice made clear that
the Administrator did not take into
account more recent studies on the
health and welfare effects of Oj because
these studies had not been assessed in
the 1986-1989 Criteria Document/
Supplement, nor had they collectively
undergone the rigorous, integrative
review process (including CASAC
review) required to incorporate them
into a new criteria document. The
proposed decision, therefore, was based
on an evaluation of key studies
published through early 1989 as
contained in the 1986-89 Criteria
Document/Supplement, the 1989 Staff
Paper assessment of the most relevant
information in these documents, and the
advice and recommendations of the
CASAC as presented both in the
discussion of these documents at public
meetings and in the CASAC's 1986 and
1989 "closure letters."
In view of the large number of recent
scientific papers and ongoing research .
on the health and welfare effects of Oj,
the August 10,1992 notice also
announced the EPA's intention to
proceed as rapidly as possible with the
next review of the air quality criteria
and standards for Oj. On March 9,1993
(58 FR 13008) the EPA published its
final decision not to revise the current
primary and secondary NAAQS for O3.
Because of the scientific and technical
complexity'of such assessments, the
EPA had estimated that 2 to 3 years
would, be necessary to rigorously assess
more than 1,000 new studies and , '
' incorporate key information into a
revised criteria document, to evaluate
the significance of the key information
for decision-making purposes; to
develop staff recommendations for the
Administrator, and to provide
appropriate opportunities for CASAC
review and public comment. Given the
potential importance of the new studies
and the EPA's continuing concern about
the health and welfare effects of Oj. the
March 9,1993 notice also indicated the
Administrator's intention to move the
review process ahead as quickly as
possible arid, if appropriate, to pjopose
revisions of the standards at the earliest
possible date.
Current -Review Process/Schedule
Following publication of the March 9,
1933 decision, the Agency, in
consultation with the CASAC and the
Science Advisor}- Board, undertook a
igorous examination of the NAAQS
eview process designed to identify all
Measures that could be taken to
ccslerate its review of toe criteria ond

Federal Register / Vol. 59, No. 23 / Thursday. February 3, 1994 / Proposed Rules
held two peer-review workshops on
draft health effects chapters of a revised,
Criteria Document (58 FR 35454} in July
1993. Additional workshops on draft air
quality and ecological effects chapters
(58 FR 48063) were held in September
1993. Since then, the EPA has discussed
the schedule and process outlined in
this notice with the CASAC (58 FR
59034). The EPA is also conducting
exposure and risk analyses. A
subcommittee of the CASAC met on
December 16.1993 to review
methodologies (58 FR 63345). A further
subcommittee meeting on risk analysis
is planned for spring 1994.
Implementation
It is important to stress that while
conducting this review, the EPA
remains committed to implementing the
existing Oj NAAQS in accordance with
the Clean Air Act Amendments of 1990
(CAAA). During the review, the EPA
will continue to work with States to
implement emission control strategies
required by the CAAA to meet the
existing O3 NAAQS. These efforts
include State and Federal actions to
reduce emissions of volatile organic
compounds and nitrogen oxides, which
act as precursors to O3 formation in the
troposphere. The EPA will make every
effort to maintain implementation
schedules consistent with requirements
of the CAAA to ensure continued
improvement in air quality.
'. As part of the review, the EPA is
examining the ramifications of any
changes to the NAAQS on current
implementation efforts. If appropriate,
new implementation rules and
guidelines will be considered for
alternative NAAQS. The EPA also is
reviewing options to ensure a smooth
transition for implementation of any
new O3 NAAQS in the event a decision
is made to revise the current O3
NAAQS.

ACTION: Proposed rules.
SUMMARY: This Notice of Proposed
Rulemaking (NPRM) proposes to amend
rules which regulate tho terms and
conditions under which customer-
provided terminal equipment may be
connected to the telephone network.
The proceeding was initiated by
petitions for rulemaking Hied by
.Southwestern Bell Telephone Company
(SWB) and Ameritech Operating
Companies (Ameritech) who ask that
regulations governing switched digital
services be added. The effect of the
proposed rules would be to promote
rapid exploitation of switched digital
technology. We propose also to provide
for a registration revocation procedure
which should greatly enhance our
ability to enforce applicable rules as
well as the Telecommunications Trade
Act of 1988; and we take this
' opportunity to propose clarifications to
other rules.
DATES: Comments were to be submitted
on or before January 13,1994, and
replies by January 28,1994; however,

Paperwork Reduction Act
Reporting and recordkeeping
activities needed to comply with the
proposed rules are usual and customary.
Analysis of Proceeding
is By this NPRM we contemplate
amending parts 2 and 68 of the rules. 47
CFR parts 2 and 68. A purpose of part
68 is to maintain uniform standards for
the protection of th£ teleDjionejcetwork
from harms caused by the connection of
terminal equipment and associated
wiring. This proceeding was initiated by
two petitions for rulemaking. one>fr1ed
by SWB (RM-7815) and the other by"'
Ameritech'(RM-6147).
2. SWB requests that part 68 be
amended to include the regulation of
terminal equipment connected to the
two:wire Basic Rate Access (BRA)
interface and to the Primary Rate Access
(PRA) interface provided by Integrated
Services Digital Network (ISDN) access
technology. BRA consists of one or two
64 Kbps information channels with a 16
Kbps channel for dialing and network
access information. The 1.544 Mbps
PRA consists of 23 64 Kbps information
channels and the 64 Kbps dialing and
network access channel. ISDN is in a
developmental phase, being deployed
these last few years in an experimental
mode. The Public Notice of SWB's
petition elicited comments from eight
parties and reply comments from three.
There was overwhelming support for
including this service in part 68 in order
to promote, on a nationwide and
worldwide basis, rapid exploitation of
this technology with minimum
mandatory criteria for connection of
CPE (customer premises equipment).
Thus, we propose for comment
technical standards for including this
service in part 68 in supplement to the
existing standards for non-switched
leased-line digital services which were
added in 1985.
3. Commenting on SWB's petition.
AT&T recommends (a) that part 68 rules
covering PRA not be limited to the two-
wire ISDN BRA service but also
authorize terminal equipment
connected to the 4-wire ISDN PRA
(1.544 Mbps) interface pursuant to
performance and compatibility
standards adopted by ANSI (American
National Standards Institute): (b) that
amendments to part 68 provide
equipment specifications for both PRA
