[KY-9917; IN92-1; FRL-6346-3]

Clean Air Act Reclassification or Extension of Attainment Date,
Kentucky and Indiana; Louisville Nonattainment Area; Ozone

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA proposes to find that the Louisville moderate ozone
nonattainment area (Louisville area) has failed to attain the one-hour
ozone National Ambient Air Quality Standard (NAAQS) by its applicable
attainment date. If EPA takes final action on this finding, the
Louisville area would be reclassified as a serious nonattainment area.
The Louisville area consists of Jefferson County and portions of
Bullitt and Oldham Counties in Kentucky, and Clark and Floyd Counties
in Indiana.
However, EPA is also proposing to extend the Louisville area's
attainment date, if Kentucky and Indiana meet the criteria of EPA's
July 16, 1998 attainment date extension policy. The extension policy
provides that a nonattainment area, such as the Louisville area, may be
eligible for an attainment date extension if it meets certain
conditions. The extension policy applies where pollution from upwind
areas interferes with the ability of a downwind area to demonstrate
attainment with the one-hour ozone standard by the dates prescribed in
the CAA. Kentucky and Indiana are working together to comply with the
conditions for receiving an extension. If Kentucky and Indiana make
submittals in response to the extension policy, EPA will address the
adequacy of those submittals in a subsequent supplemental proposal. If
the submittals meet the criteria for an extension, the attainment date
for the Louisville area will be extended, and the area will not be
reclassified. EPA does not intend to take final action on
reclassification of the Louisville area prior to allowing the area an
opportunity to qualify for an attainment date extension under the
extension policy.

DATES: Comments must be received on or before June 21, 1999.

ADDRESSES: All comments should be addressed to: Kay Prince, Section

I. What Action Is Being Taken in This Document?

EPA is proposing to find that the Louisville area has failed to
attain the one-hour ozone NAAQS by the November 15, 1996, attainment
deadline prescribed under the CAA for moderate ozone nonattainment
areas, or by the November 15, 1997 extended deadline granted to the
Louisville area under Section 181 (a)(5) of the CAA. EPA's authority to
make this finding is discussed under section 181(b)(2) of the CAA.
Section 181(b)(2) explains EPA's responsibility to determine whether an
area has attained the one-hour ozone standard, and its duty to
reclassify the area if necessary. If EPA finalizes this finding, the
Louisville area will be reclassified by operation of law from moderate
nonattainment to serious nonattainment.
Alternatively, EPA is also proposing to extend the Louisville
area's attainment date, provided that Kentucky and Indiana submit State
Implementation Plans (SIPs) pursuant to EPA's July 16, 1998 policy,
entitled ``Guidance on Extension of Air Quality Attainment Dates for
Downwind Transport Areas'' (Richard D. Wilson, Acting Assistant
Administrator for Air and Radiation) by November 15, 1999. If the
States meet the extension policy criteria and EPA proposes to approve
the States' submittals, then a specific extended attainment date will
be proposed in the same notice. EPA will take final action on the new
attainment date at the time it takes final action on the attainment
demonstration and the other necessary submittals. However, if Kentucky
and Indiana fail to meet the criteria of the extension policy, EPA will
finalize this proposed finding of

[[Page 27735]]

failure to attain, and the Louisville area will be reclassified to a
serious ozone nonattainment area.
EPA believes that this approach is reasonable since it (1) ensures
that the local control measures mandated by the CAA for moderate
nonattainment areas, such as Volatile Organic Compound (VOC) and
Nitrogen Oxides (NOx) Reasonably Available Control Technology (RACT),
are achieved; (2) takes into consideration the transport of pollutants
into the Louisville area which impair the ability of the area to meet
the air quality standards; and (3) harmonizes the Louisville area
attainment date with the schedule for emissions reductions in upwind
areas associated with the NOx SIP call.

II. What Are the National Ambient Air Quality Standards?

Since the CAA's inception in 1970, EPA has set NAAQS for six common
air pollutants: carbon monoxide, lead, nitrogen dioxide, ozone,
particulate matter, and sulfur dioxide. For these common air pollutants
there are two types of pollution limits referred to as the primary and
secondary standard. The primary standard is based on health effects;
and the secondary standard is based on environmental effects such as
damage to property, plants, and visibility. The CAA requires these
standards be set at levels that protect public health and welfare with
an adequate margin of safety. These standards allow the American people
to assess whether or not the air quality in their communities is
healthful. Also, the NAAQS present state and local governments with the
air quality levels they must meet to achieve clean air.

III. What Is the NAAQS for Ozone?

The NAAQS for ozone is expressed in two forms which are referred to
as the one-hour and eight-hour standards. Table 1 summarizes the ozone
standards.

Table 1.--Summary of Ozone Standards
----------------------------------------------------------------------------------------------------------------
Value
Standard (parts per Type Method of compliance
million)
----------------------------------------------------------------------------------------------------------------
1-hour.............................. 0.12 Primary and secondary.. Concentration of ozone monitored in
ambient air must not exceed standard
value, on average, more than one day
per year over any 3-year period.
8-hour.............................. 0.08 Primary and secondary.. The 3-year average of the annual
fourth highest daily maximum 8-hour
average ozone concentration measured
at each monitor within an area must
be equal to or below the standard
value.
----------------------------------------------------------------------------------------------------------------

The one-hour ozone standard of 0.12 ppm has existed since 1979. The
eight-hour ozone standard, which replaces the one-hour standard, was
adopted by EPA on July 18, 1997 (62 FR 38856). However, the one-hour
ozone standard continues to apply for existing nonattainment areas
until such time as EPA determines that the area has attained the one-
hour ozone standard (40 CFR 50.9(b)). The one-hour standard continues
to apply to the Louisville area and it is the classification of the
Louisville area relative to the one-hour ozone standard that is
addressed in this document.

IV. What Is the Louisville Ozone Nonattainment Area?

The Louisville ozone nonattainment area is an interstate area which
includes counties in both Kentucky and Indiana as follows: Jefferson
County and portions of Bullitt and Oldham Counties in Kentucky; and
Clark and Floyd Counties in Indiana.
Under section 107(d)(1)(C) of the CAA, each area that EPA
designated nonattainment for the one-hour ozone standard prior to
enactment of the 1990 CAA amendments, such as the Louisville area,
retained its nonattainment designation by operation of law upon
enactment of the 1990 amendments. Under section 181(a) of the Act, each
ozone nonattainment area was also classified by operation of law as
``marginal,'' ``moderate,'' ``serious,'' ``severe,'' or ``extreme,''
depending on the severity of the area's air quality problem. The design
value for a nonattainment area, which characterizes the severity of the
area's air quality problem, is represented by the highest design value
at any individual ozone monitoring site. The design value of a
monitoring site is the fourth highest one-hour daily maximum ozone
value recorded in a given three-year period with complete monitoring
data. Table 2 provides the design value ranges for each nonattainment
classification. Ozone nonattainment areas with design values between
0.138 and 0.160 ppm were classified as moderate, such as the Louisville
area which had a design value of 0.149 ppm in 1989. These nonattainment
designations and classifications were codified in 40 CFR part 81 (see
56 FR 56694, November 6, 1991).

Table 2.--Ozone Nonattainment Classifications
----------------------------------------------------------------------------------------------------------------
Area class Design value (ppm) Attainment date
----------------------------------------------------------------------------------------------------------------
Marginal................................ 0.121 up to 0.138.............. November 15, 1993.
Moderate................................ 0.138 up to 0.160.............. November 15, 1996.
Serious................................. 0.160 up to 0.180.............. November 15, 1999.
Severe.................................. 0.180 up to 0.280.............. November 15, 2005.
Extreme................................. 0.280 and above................ November 15, 2010.
----------------------------------------------------------------------------------------------------------------

[[Page 27736]]

Under section 182(b)(1)(A) of the CAA, states containing areas that
were classified as moderate nonattainment were required to submit SIPs
to provide for certain controls, to show progress toward attainment,
and to provide for attainment of the ozone standard no later than
November 15, 1996. Moderate area SIP requirements are found primarily
in section 182(b) of the CAA.

V. Why Is EPA Proposing To Reclassify the Louisville Area?

In regard to reclassification for failure to attain, section
181(b)(2)(A) of the Act provides that:
Within 6 months following the applicable attainment date (including
any extension thereof) for an ozone nonattainment area, the
Administrator shall determine, based on the area's design value (as of
the attainment date), whether the area attained the standard by that
date. Except for any Severe or Extreme area, any area that the
Administrator finds has not attained the standard by that date shall be
reclassified by operation of law in accordance with table 1 of
subsection (a) to the higher of--
(i) the next higher classification for the area, or
(ii) the classification applicable to the area's design value as
determined at the time of the notice required under subparagraph (B).

No area shall be reclassified as Extreme under clause (ii).
Furthermore, section 181(b)(2)(B) of the CAA provides that:
The Administrator shall publish a notice in the Federal Register,
no later than 6 months following the attainment date, identifying each
area that the Administrator has determined under subparagraph (A) as
having failed to attain and identifying the reclassification, if any,
described under subparagraph (A).
Table 3 lists the number of days when ambient ozone concentrations
exceeded the one-hour ozone standard and the average number of expected
exceedances at each monitoring site in the Louisville area for the
period 1994-1996. The ozone design value for each monitor is also
listed. Note that the average number of expected exceedances per year
is not always equal to the average number of days with measured ozone
above the standard. Expected exceedance calculations take missing data
into account. If a monitor does not collect a complete set of valid
data over its monitored period, fractional ``expected exceedances'' are
added to account for ozone exceedances that, statistically, could have
occurred during periods of missing data within high ozone episodes. The
three year average number of expected exceedances is used to determine
attainment of the ozone standard. See 40 CFR 50.9(a). Table 3 shows
that for 1994-1996, one monitoring site in the Louisville area averaged
more than one exceedance day per year; therefore, the area did not
attain the standard by November 15, 1996.
Section 181(a)(5) of the CAA states that an area may be eligible
for up to two one-year extensions if ``no more than one exceedance of
the NAAQS level for ozone has occurred in the area in the year
preceding the extension year.'' On October 23, 1997, EPA determined
that Louisville qualified for a one-year extension of the attainment
date to November 15, 1997 (See 62 FR 55173). Table 4 shows the ozone
data for 1995-1997. During this period, two monitoring sites in the
Louisville area averaged more than one exceedance per year, and the
area's design value was greater than the ozone standard. Because there
were multiple exceedances at two monitors during the 1997 ozone season,
the Louisville area was not eligible for a second one-year extension
under Section 181(a)(5), and the states did not request an extension.
Therefore, in this notice, pursuant to section 181(b)(2)(B) of the CAA,
EPA proposes to find that the Louisville area did not attain the 1-hour
standard by its applicable attainment date.

Table 5 is provided to show expected exceedance days per year for
1995 through 1998. Due to measured ozone exceedances at one monitor,
the Louisville area was again unable to attain the standard for the

As discussed later in this document, because EPA has now
interpreted the CAA to allow for an extension of the attainment date
based on an understanding of transport data not available at the time
of Louisville's original attainment date and after the one year
extended attainment date, EPA believes it is fair to allow Kentucky and
Indiana an opportunity to qualify for this attainment date extension
before EPA finalizes its finding of failure to attain and reclassifies
the Louisville area to serious nonattainment.
This proposal details the following reasons which support EPA's
decision to proceed in this manner:
1. EPA has concluded that this is the best way of reconciling the
CAA's provisions with respect to ozone transport with the provisions
governing graduated attainment dates and with the reclassification
provisions. The CAA shows Congressional intent that transport be
considered when the Agency acts to reclassify an area, and a reluctance
to subject an area to greater controls than necessary to bring local
sources into compliance.
2. The Louisville area has been shown to be affected by ozone
transport from upwind areas.
3. The Louisville area is now monitoring air quality that, were the
area being newly classified, would entitle it to the classification of
a marginal nonattainment area. However, if the Louisville area is
reclassified to serious nonattainment, it will be required to impose
emission control regulations which are normally demanded only for areas
monitoring much higher levels of air pollution.
4. Kentucky and Indiana have committed to submit an attainment
demonstration by November 1999, which includes all the local control
measures required under the CAA for moderate nonattainment areas,
demonstrating attainment by the date when upwind controls are expected
to be implemented.
Furthermore, EPA's proposal for an extension date is balanced by
EPA's action in moving forward with the process of reclassification in
the event that the States do not meet the criteria for an extension.

VI. What Is EPA's New Policy Regarding Extension of Attainment
Dates for Downwind Transport Areas?

A number of areas in the country that have been classified as
``moderate'' or ``serious'' are affected by pollutants that have
traveled downwind from other areas. For these downwind areas, transport
of pollutants from upwind areas has interfered with their ability to
meet the ozone standard by the dates prescribed by the CAA. As a
result, many of these areas, such as the Louisville area, find
themselves facing the prospect of being reclassified to a higher
classification (e.g., from ``moderate'' to ``serious'') for failing to
meet the ozone standard by the specified date.
For some time, EPA has recognized that pollutant transport can
impair an area's ability to meet air quality standards. As a result, in
March 1995 a collaborative, Federal-state process to assess the ozone
transport problem was begun. Through a two-year effort known as the
Ozone Transport Assessment Group (OTAG), EPA worked in partnership with
the 37 easternmost states and the District of Columbia, industry
representatives, academia, and environmental groups to develop
recommended strategies to address transport of ozone-forming pollutants
across state boundaries.
On November 7, 1997, EPA acted on OTAG's recommendations and issued
a proposal (the proposed NO_X SIP call, 62 FR 60318)
requiring 22 states and the District of Columbia to submit state
implementation plans addressing the regional transport of ozone. These
state implementation plans, or SIPs, will decrease the transport of
ozone across state boundaries in the eastern half of the United States
by reducing emissions of NO_X (a precursor to ozone
formation). EPA took final action on the NO_X SIP call on
October 27, 1998 (63 FR 57356). EPA expects that the final
NO_X SIP call

[[Page 27738]]

will assist many areas in attaining the one-hour ozone standard.
On July 16, 1998, in consideration of these factors and the
realization that many areas are unable to meet the CAA mandated
attainment dates due to transport, EPA issued the extension policy. In
this policy the attainment date for an area may be extended provided
that the following criteria are met: (1) the area must be identified as
a downwind area affected by transport from either an upwind area in the
same state with a later attainment date or an upwind area in another
state that significantly contributes to downwind nonattainment (by
``affected by transport,'' EPA means an area whose air quality is
affected by transport from an upwind area to a degree that affects the
area's ability to attain); (2) an approvable attainment demonstration
must be submitted with any necessary, adopted local measures and with
an attainment date that shows that it will attain the one-hour standard
no later than the date that the reductions are expected from upwind
areas under the final NO_X SIP call and/or the statutory
attainment date for upwind nonattainment areas, i.e., assuming the
boundary conditions reflecting those upwind reductions; (3) the area
has adopted all applicable local measures required under the area's
current classification and any additional measures necessary to
demonstrate attainment, assuming the reductions occur as required in
the upwind areas; and (4) the area must provide that it will implement
all adopted measures as expeditiously as practicable, but no later than
the date by which the upwind reductions needed for attainment will be
achieved.
EPA contemplates that when it acts to approve such an area's
attainment demonstration, it will, as necessary, extend that area's
attainment date to a date appropriate for that area in light of the
schedule for achieving the necessary upwind reductions. The area would
no longer be subject to reclassification for failure to attain by its
original attainment date under section 181(b)(2).

VII. Is the Louisville Area Eligible for an Attainment Date
Extension Under the Extension Policy?

EPA believes that the Louisville area is affected by upwind
transport. In fact, according to the final NO_X SIP call, the
Louisville area is affected by transport of pollutants from upwind
areas to an extent that the area's ability to meet the one-hour ozone
standard is impaired. Therefore, EPA believes that the first of the
transport criteria is satisfied. However, before the Louisville area
can qualify for an attainment date extension under the extension
policy, the remainder of the criteria specified in the extension policy
must be met.
In October 1998, EPA notified the Governors of Kentucky and Indiana
of the availability of the extension policy. EPA also requested that,
if they wished to demonstrate their eligibility for the extension
policy, the Governors respond to EPA with a letter committing their
respective States to meet the requirements necessary to qualify for an
attainment date extension under the policy by November 15, 1999.
On December 3, 1998, Kentucky submitted a letter to EPA providing a
commitment to meet the requirements of the extension policy. Similarly,
on December 19, 1998, Indiana submitted a letter to EPA providing a
commitment to meet the requirements of the extension policy. (EPA's
letters notifying the Kentucky and Indiana Governors of the extension
policy, and their respective responses, are included in the docket for
this rulemaking.)
EPA's review of the Attainment Demonstration SIP for the Louisville
area indicates that Kentucky and Indiana must submit the following in
order to meet the requirements set forth in the extension policy:
1. A technical analysis establishing the influence of transport on
ozone levels within the Louisville area. This requirement can be met by
citing the analysis contained in EPA's aforementioned NO_X
SIP call;
2. Regulations or negative declarations addressing certain CAA
requirements for the Indiana portion of the Louisville area including:
(a) Synthetic Organic Chemical Manufacturing Industry (SOCMI)
distillation; (b) SOCMI reactors; (c) Lithography; (d) Batch processes;
(e) Industrial wastewater treatment; (f) Business plastics; (g) Cleanup
solvents; and (h) Aerospace coatings;
3. Source specific reasonably available control technology
(NO_X RACT) measures for the Kentucky portion of the
Louisville area; and
4. A revised attainment demonstration meeting the criteria set
forth in the extension policy.
In addition, the States must submit SIP revisions addressing any
other local control measures necessary for attainment. All measures
must also be implemented in accordance with the time frames set forth
in the extension policy.

VIII. What Progress Has Been Made by Kentucky and Indiana To Meet
the Extension Policy so That an Attainment Date Extension Can Be
Obtained?

Kentucky and Indiana have already done extensive work toward
meeting the extension policy. Several major portions of the extension
policy have already been satisfied, and Kentucky and Indiana have
already made substantial progress toward compliance with the criteria
for obtaining an attainment date extension.
Regarding the first item, EPA believes that Kentucky and Indiana
can establish the influence of transport on ozone levels within the
Louisville area by citing the analysis contained in EPA's
NO_X SIP call.
Regarding the second item, Indiana is reviewing the source
inventory for Clark and Floyd Counties. Indiana has committed to either
develop RACT regulations if those source categories exist in Clark and
Floyd Counties, or make a formal declaration that no subject sources of
the category exist in the two counties. Kentucky has already met the
VOC RACT requirements.
Regarding the third item, the Air Pollution Control District of
Jefferson County, Kentucky has developed and is currently adopting a
NO_X RACT regulation that requires Jefferson County area
sources to submit source specific SIP revisions consistent with
NO_X RACT requirements. For the remaining part of the
Louisville area which includes portions of Bullitt and Oldham Counties
there are no existing major NO_X emission sources, therefore
the Commonwealth of Kentucky is not required to implement
NO_X RACT requirements for that area. Indiana has already met
the NO_X RACT requirements.
Regarding the fourth item, Kentucky and Indiana are currently
working to develop an approvable attainment demonstration. They have
initiated the steps leading to a final attainment demonstration and
have committed to completing and submitting the attainment
demonstration by November 15, 1999.

IX. What Actions Have Kentucky and Indiana Taken To Improve Air
Quality in the Louisville Area?

Jefferson County, Kentucky, has implemented VOC emission reductions
as part of its 15 percent rate-of-progress plan (15 percent plan). EPA
is currently drafting rulemaking on this plan. The VOC controls
Jefferson County has implemented include: (1) VOC emission reduction
requirements and a rule effectiveness improvement plan for

[[Page 27739]]

sources subject to the requirements; (2) architectural and industrial
maintenance coatings regulations; (3) transportation control measures
including transit, rideshare, alternative fuels, and traffic signal
improvements; (4) automobile refinishing emission control regulations;
(5) Stage II vapor recovery and control regulation; (6) solid waste
landfill regulations; (7) a basic plus vehicle inspection and
maintenance (I/M) program which includes loaded idle testing, pressure
testing requirements, and tampering inspections which apply to vehicles
that regularly or routinely commute to Jefferson County; and (8) the
use of the reformulated gasoline (RFG) program for off-road and on-road
mobile sources.
Jefferson County has sought further reductions from the I/M program
by including loaded mode testing and enhanced mechanic training. EPA
recently approved Jefferson County's I/M program requirement for a
check of the On Board Diagnostic (OBD) system on model-year 1996 and
newer automobiles (refer to 64 FR 12798, March 15, 1999). Jefferson
County has maintained an innovative approach to the local I/M program,
also referred to as the Vehicle Emission Testing (VET) program, since
its inception in 1984. The program continues to be effectively
implemented and Jefferson County remains a national leader through, for
example, implementation of a vehicle repair report card which evaluates
the effectiveness of automobile repairs required under the I/M program.
The program also remains on the forefront with the requirement for the
evaluation of automobiles by a VET staff mechanic before an emission
certification waiver request is granted. The I/M program is an
important component of the emission reduction strategy in Jefferson
County.
Jefferson County has adopted RACT regulations requiring additional
emission reductions from bakery oven facilities, ferroalloy and calcium
carbide production facilities, and volatile organic loading facilities.
Jefferson County plans to submit these RACT regulations to EPA in the
near future. To provide further emission reductions, Jefferson County
is currently adopting a cold cleaning operations regulation.
The State of Indiana has also taken a number of actions to improve
air quality in the Louisville area. Indiana has adopted and fully
implemented the VOC emission reduction measures included in its 15
percent rate-of-progress plan (15 percent plan). EPA published final
approval of Indiana's 15 percent plan in May 1997 (62 FR 24815).
Indiana's 15 percent plan limits VOC emissions from local
operations such as volatile organic liquid storage tanks, automobile
refinishing, municipal solid waste landfills, ship building and ship
repair, and a local offset printing facility. The plan also includes an
upgraded vehicle inspection and maintenance program, which uses a
dynamometer to better identify polluting cars. Other measures in place
include required use of Stage II gasoline vapor recovery systems at
service stations, implementation of a gasoline with lower Reid Vapor
Pressure (RVP); a ban on residential open burning, and a ridesharing
program. Municipal solid waste landfills were required to install a gas
collection and combustion system sooner than the federal time schedule.
Indiana has also implemented RACT rules for sources of NO_X.
To further improve air quality, Indiana has implemented additional
measures including a rule establishing vapor pressure limits for
solvents used in cold cleaning degreasing. Indiana has also established
a local steering committee to assist in identifying additional emission
reduction opportunities that will continue to improve and maintain air
quality. The steering committee reflects broad representation including
the public, industry, local government, health associations, and
environmental groups.

X. If EPA Finalizes Its Proposed Rulemaking Reclassifying the
Louisville Area, What Would Be the Area's New Classification?

Section 181(b)(2)(A) of the Act requires that, when an area is
reclassified for failure to attain, its reclassification will be the
higher of the next higher classification or the classification
applicable to the area's ozone design value at the time the notice of
reclassification is published in the Federal Register. The design value
of the Louisville area at the time of the proposed finding of failure
to attain is based on air quality monitoring data from 1996 through
1998. (Refer to Table 5 for 1996-1998 data.) The 1996-1998 design value
is 0.130 ppm, as derived from the Charlestown, Indiana (Clark Co.)
monitoring site, and the classification of ``marginal'' nonattainment
would be applicable to that design value. By contrast, because the
Louisville area is currently classified ``moderate,'' the next higher
classification for the area is ``serious'' nonattainment. Since
``serious'' is a higher nonattainment classification than ``marginal''
under the statutory scheme, the Louisville area would be reclassified
to serious nonattainment, if EPA finalizes its proposal to reclassify.

XI. If the Louisville Area Is Reclassified to Serious, When Would
It Be Required To Attain the Standard?

Under section 181(a)(1) of the Act, the new attainment deadline for
moderate ozone nonattainment areas reclassified to serious under
section 181(b)(2) would be ``as expeditious as practicable,'' but no
later than the date applicable to the new classification, i.e.,
November 15, 1999. However, EPA does not expect to take final action on
this proposed reclassification until after November 15, 1999. As stated
previously, EPA is proposing to allow the states adequate time to
demonstrate that an extension of the attainment date, instead of a
reclassification, would be appropriate under the extension policy. As a
practical matter, even if EPA were to reclassify the Louisville area
immediately, there would likely be insufficient time for Kentucky and
Indiana to submit new attainment demonstrations and actually attain the
one-hour ozone standard by November 15 of this year. EPA believes that
the practical impossibility of meeting the November 1999 statutory
serious area attainment deadline requires EPA to establish a new
attainment date for the area. EPA believes that it is appropriate to
propose an alternative deadline for the Louisville area that is as
expeditious as practicable. Therefore, in this document EPA is
proposing options for extending the attainment date in the event that
the area is reclassified to serious.
Section 182(i) states that the Administrator may adjust applicable
deadlines (other than attainment dates) to the extent such adjustment
is necessary or appropriate to assure consistency for submission of the
new requirements applicable to an area which has been reclassified.
Where an attainment date has already passed or is otherwise impossible
to meet, EPA believes that the Administrator may also adjust an
attainment date to assure fair and equitable treatment consistent with
the provisions in section 182(i), notwithstanding the parenthetical
clause. EPA also notes another provision of the CAA in section
110(k)(5) pertaining to findings of SIP inadequacy that allows the
Administrator to adjust attainment dates when such dates have passed.
Although this latter provision is not directly applicable to a
reclassification, EPA believes that the provision illustrates a
recognition by Congress of the limited instances in which it becomes
necessary to adjust attainment dates, particularly

[[Page 27740]]

where it is otherwise impossible to meet the statutory date.
One option is to construct a schedule consistent with recent
reclassifications of other areas. EPA has recently reclassified other
moderate ozone nonattainment areas, including Santa Barbara,
California; Phoenix, Arizona; and Dallas-Fort Worth, Texas. The
attainment date for these areas is November 15, 1999. EPA published the
notice reclassifying the Dallas-Fort Worth area on February 18, 1998,
thereby providing approximately 21 months for the area to attain the
standard. EPA concluded that 21 months was an adequate period for a
moderate attainment area to attain the standard where the CAA mandated
attainment date for the new classification had not yet lapsed, but
where there was less time remaining than the Act had contemplated. If
EPA finalizes this proposed reclassification of the Louisville area,
EPA could require the area to attain the standard on a similar time
frame. Applying this approach to the Louisville area would result in
setting a new attainment date 21 months from publication of the final
reclassification notice.
Another option would be to set an attainment date that takes into
account the impact of transport on the area, even if the area fails to
fully meet the criteria for the attainment date extension policy. As
stated previously, EPA believes that the Louisville area is affected by
transported pollutants. This attainment date would coincide with the
date set for upwind area reductions under the NO_X SIP call,
or May 2003. Although the Louisville area, if reclassified, would have
to meet the requirements for a serious area, under this option it would
not be held responsible for emission reductions necessary to compensate
for transported pollution. This option would then be consistent with
EPA's approach of allocating responsibility for pollution fairly among
the states. EPA welcomes any comments on the options discussed above.
An area reclassified to serious is required to submit SIP revisions
addressing the serious area requirements for the one-hour ozone
standard in section 182(c). If the Louisville area is reclassified, EPA
must also address the schedule by which Kentucky and Indiana are
required to submit SIP revisions meeting the serious area requirements.
One option is to require that the States submit SIP revisions
containing all of the serious area requirements no later than one year
after final action on the reclassification. This submission would
include a new attainment demonstration and all additional measures
required by section 182(c) of the Act. The additional measures include,
but are not limited to, the following: (1) Attainment and reasonable
further progress demonstrations; (2) an enhanced vehicle I/M program;
(3) a clean-fuel vehicle program; (4) a 50 ton-per-year major source
threshold; (5) more stringent new source review requirements; (6) an
enhanced monitoring program; and (7) contingency provisions. If the
submission shows that the area can attain the standard sooner than the
attainment date established in a final reclassification notice, EPA
would adjust the attainment date to reflect the earlier date,
consistent with the requirement in section 181(a)(1) that the standard
be attained as expeditiously as practicable. EPA solicits comments on
the appropriate schedule for submitting these SIP revisions.

XII. When Will EPA Make a Final Decision on Whether To Reclassify
or Grant an Extension to the Louisville Area?

If Indiana and Kentucky submit the aforementioned air quality
analyses and regulations to EPA by November 15, 1999, EPA will publish
a supplemental proposal to address the approvability of the submittals.
If EPA proposes and subsequently takes final action to approve the
States' submittals, the Agency would finalize the attainment date
extension for the Louisville area to an appropriate date, and not
finalize the finding of failure to attain. However, if EPA proposes and
subsequently takes final action to disapprove the States' submittals,
the Agency would instead finalize the reclassification of the
Louisville area to serious. If EPA finalizes the reclassification,
Kentucky and Indiana would be required to submit SIPs that adopt the
serious area requirements. A schedule for submitting the SIPs would be
set at that time.

XIII. Administrative Requirements

A. Executive Order 12866

The Office of Management and Budget (OMB) has exempted this
regulatory action from E.O. 12866 entitled ``Regulatory Planning and
Review.''

B. Executive Order 12875

Under E.O. 12875, Enhancing the Intergovernmental Partnership, EPA
may not issue a regulation that is not required by statute and that
creates a mandate upon a state, local, or tribal government, unless the
Federal government provides the funds necessary to pay the direct
compliance costs incurred by those governments, or EPA consults with
those governments. If EPA complies by consulting, E.O. 12875 requires
EPA to provide to the OMB a description of the extent of EPA's prior
consultation with representatives of affected state, local, and tribal
governments, the nature of their concerns, copies of any written
communications from the governments, and a statement supporting the
need to issue the regulation. In addition, E.O. 12875 requires EPA to
develop an effective process permitting elected officials and other
representatives of state, local, and tribal governments ``to provide
meaningful and timely input in the development of regulatory proposals
containing significant unfunded mandates.''
Today's proposal would not create a mandate on state, local, or
tribal governments. It would not impose any enforceable duties on these
entities. The SIP submission requirements are not judicially
enforceable. Accordingly, the requirements of section 1(a) of E.O.
12875 do not apply to this proposal.

C. Executive Order 13045

Protection of Children from Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997) applies to any rule that: (1) is
determined to be ``economically significant'' as defined under E.O.
12866, and (2) concerns an environmental health or safety risk that EPA
has reason to believe may have a disproportionate effect on children.
If the regulatory action meets both criteria, the Agency must evaluate
the environmental health or safety effects of the planned rule on
children, and explain why the planned regulation is preferable to other
potentially effective and reasonably feasible alternatives considered
by the Agency.
This proposal is not subject to E.O. 13045 because it is not an
economically significant regulatory action as defined by E.O. 12866,
and it does not establish a further health or risk-based standard
because it implements a previously promulgated health or safety-based
standard.

D. Executive Order 13084

Under E.O. 13084, Consultation and Coordination with Indian Tribal
Governments, EPA may not issue a regulation that is not required by
statute, that significantly or uniquely affects the communities of
Indian tribal governments, and that imposes substantial direct
compliance costs on those communities, unless the Federal government
provides the funds necessary to pay the direct compliance costs
incurred by the tribal

[[Page 27741]]

governments, or EPA consults with those governments. If EPA complies by
consulting, E.O. 13084 requires EPA to provide to the OMB, in a
separately identified section of the preamble to the rule, a
description of the extent of EPA's prior consultation with
representatives of affected tribal governments, a summary of the nature
of their concerns, and a statement supporting the need to issue the
regulation. In addition, E.O. 13084 requires EPA to develop an
effective process permitting elected officials and other
representatives of Indian tribal governments ``to provide meaningful
and timely input in the development of regulatory policies on matters
that significantly or uniquely affect their communities.''
Today's proposal would not significantly or uniquely affect tribal
governments. Accordingly, the requirements of section 3(b) of E.O.
13084 do not apply to this proposal.

E. Regulatory Flexibility Act

The Regulatory Flexibility Act generally requires an agency to
conduct a regulatory flexibility analysis of any rule subject to notice
and comment rulemaking requirements, unless the agency certifies that
the rule will not have a significant economic impact on a substantial
number of small entities. Small entities include small businesses,
small not-for-profit enterprises, and small governmental jurisdictions.
This proposal will not have a significant impact on a substantial
number of small entities because a finding of failure to attain under
section 181(b)(2) of the CAA, and the establishment of a SIP submittal
schedule for the reclassified area, do not, in and of themselves,
directly impose any new requirements on small entities. See Mid-Tex
Electric Cooperative, Inc. v. FEC., 773 F.2d 327 (D.C. Cir. 1985)
(agency's certification need only consider the rule's impact on
entities subject to requirements of the rule). Instead, this proposal
proposes to make a determination and to establish a schedule for states
to submit SIP revisions and does not propose to directly regulate any
entities. Therefore, I certify that this action will not have a
significant economic impact on a substantial number of small entities.

F. Unfunded Mandates

Under section 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA
must, unless otherwise prohibited by law, prepare a budgetary impact
statement to accompany any proposed or final rule that includes a
Federal mandate that may result in estimated annual costs to state,
local, or tribal governments in the aggregate; or to private sector, of
$100 million or more. Under section 205, EPA must select the most cost-
effective and least burdensome alternative that achieves the objectives
of the rule and is consistent with statutory requirements. Section 203
requires EPA to establish a plan for informing and advising any small
governments that may be significantly or uniquely impacted by the rule.
Sections 202 and 205 do not apply to today's action because the
proposed determination that the Louisville area failed to reach
attainment does not, in-and-of-itself, constitute a Federal mandate
because it does not impose an enforceable duty on any entity. In
addition, the CAA does not permit EPA to consider the types of analyses
described in section 202, in determining whether an area has attained
the ozone standard or qualifies for an extension. Finally, section 203
does not apply to today's proposal because the SIP submittal schedule
would affect only the states of Kentucky and Indiana, which are not
small governments.
