Agency (EPA).
ACTION: Proposed rule.
AGENCY:
SUMMARY: EPA is proposing to approve
four related revisions to the Kentucky
State Implementation Plan (SIP)
submitted by the Commonwealth of
Kentucky on November 12, 2004. These
revisions affect the Northern Kentucky
area, which is comprised of the
Kentucky Counties of Boone, Campbell,
and Kenton, and is part of the
Cincinnati-Hamilton Metropolitan
Statistical Area. EPA is proposing to
approve the movement of the regulation
underlying the Northern Kentucky
inspection and maintenance (I/M)
program from the active portion of the
Kentucky SIP to the contingency
measures section of the Northern
Kentucky 1-Hour Ozone Maintenance
Plan. EPA is also proposing to approve
revisions to a Kentucky rule which
provides for the control of volatile
organic compounds from new solvent
metal cleaning equipment. Further, EPA
proposes to add a new rule to the
Kentucky SIP affecting commercial
motor vehicle and mobile equipment
refinishing operations in Northern
Kentucky. Finally, EPA is proposing to
approve updated mobile source category
emission projections using MOBILE6.2,
with updated, subarea motor vehicle
emission budgets (MVEBs) for the year
2010. EPA’s final approval is contingent
upon Kentucky making some
clarifications in the final SIP submittal.

I. What Changes to the Kentucky SIP
Were Submitted for EPA Approval?
In response to a Kentucky Legislative
action signed by the Governor on April
9, 2004, Kentucky submitted to EPA a
proposed revision to the Kentucky SIP
on November 12, 2004, for parallel
processing. This revision affects
regulation 401 KAR 65:010, ‘‘Vehicle
emission control programs,’’ which is a
SIP-approved regulation underlying the
Northern Kentucky I/M program, also
known as the Northern Kentucky
Vehicle Emissions Testing (VET)
Program. Kentucky has requested to
move the VET Program regulation from
the active control measures portion of
the SIP to the contingency measures
portion of the Northern Kentucky 1Hour Ozone Maintenance Plan, which is
part of the Kentucky SIP. The Northern
Kentucky VET Program is a basic I/M
program that includes on-board
diagnostics (i.e., OBD) and results in
emissions reductions of nitrogen oxides
(NOX), volatile organic compounds
(VOC), and carbon monoxide (CO). The
VET Program began testing vehicles in
Boone, Campbell, and Kenton Counties
in September 1999, to help meet
nonattainment area requirements for the
ozone NAAQS effective at the time.
The Northern Kentucky area is
comprised of the Kentucky Counties of
Boone, Campbell, and Kenton, and is
part of the Cincinnati-Hamilton
Metropolitan Statistical Area (MSA).
Presently, Boone, Campbell, and Kenton
Counties comprise the Northern
Kentucky portion of the Cincinnati 1Hour Ozone Maintenance Area. This
maintenance status means these
counties were formerly designated
nonattainment for the 1-hour ozone
standard, are now attaining this
standard, and have since been
redesignated to attainment for the 1hour ozone standard effective July 5,
2000 (July 31, 2002, 67 FR 49600). This
area was previously classified as a
moderate ozone nonattainment area. As
such, the area was required to
E:\FR\FM\04APP1.SGM
04APP1
Federal Register / Vol. 70, No. 63 / Monday, April 4, 2005 / Proposed Rules
implement a basic I/M program under
section 182(b)(4) of the Clean Air Act.
Kentucky’s November 12, 2004, draft
SIP submittal proposes to implement
new emission reductions to compensate
for the NOX and VOC emission
increases resulting from removing the
Northern Kentucky VET Program as an
active control measure in the SIP. To
demonstrate non-interference with
applicable requirements of the Act
through replacement emissions
reductions, the compensating emissions
reductions must be equivalent to or
greater than those achieved with the
VET Program. Equivalent emissions
reductions are needed to replace an
anticipated increase of 0.78 tons per
summer day (tpsd) of VOC and 0.29
tpsd of NOX in the year 2005 due to
closure of the VET Program. These
replacement VOC and NOX emissions
reductions must also occur in a time
period contemporaneous to the VET
Program’s closure, as explained further
in section IV. The VOC and NOX
replacement emissions reductions are
needed to support a demonstration of
non-interference with the 8-hour ozone
and fine particulate matter (PM2.5)
NAAQS.
The VET Program also reduces CO
emissions. In response to EPA
comments on the November proposal,
Kentucky will also include a
demonstration of non-interference with
the CO NAAQS in the final SIP
submittal to address the CO emission
increases due to discontinuation of the
VET Program.
The November 12, 2004, submittal
proposes VOC emissions reductions
from two Kentucky rules. The revisions
to Kentucky rule 401 KAR 59:185, ‘‘New
solvent metal cleaning equipment,’’
requires the use of VOC solvents with
lower vapor pressures in batch cold
cleaning machines used in specified
facilities located in the Northern
Kentucky Counties of Boone, Campbell,
and Kenton. These revisions were
originally submitted to EPA on July 16,
2004. Kentucky’s public hearing on the
proposed amendments to 401 KAR
59:185 was held August 25, 2004, with
written comments due by August 31,
2004. In a letter dated August 31, 2004,
EPA concurred with the revisions and
the analysis for estimating VOC
emissions reductions from these rule
changes. (A copy of this letter is located
on the RME Web site under the Docket
ID, R04–OAR–2004–KY–0003.) The
November 12, 2004, submittal, which
replaces the July 16, 2004, proposed SIP
revision, also proposes to add a new
rule, 401 KAR 59:760, ‘‘Commercial
Motor Vehicle and Mobile Equipment
Refinishing Operations,’’ to the
VerDate jul<14>2003
15:01 Apr 01, 2005
Jkt 205001
Kentucky SIP. This new regulation
requires the use of high transfer
efficiency application techniques at auto
body repair and refinishing operations,
and prescribes operating procedures to
minimize the emissions of VOCs. The
Commonwealth also enacted and
included in the November 12, 2004,
submittal an emergency version of rule
401 KAR 59:760, i.e., 401 KAR 59:760E,
with a State effective date of November
15, 2004, and a compliance date of
February 1, 2005. EPA is not taking
action on this emergency regulation, 401
KAR 59:760E. The public hearing on
rule 401 KAR 59:760 and movement of
the VET Program to the contingency
measures list was held on January 4,
2005.
Under the parallel processing
procedure, the Commonwealth of
Kentucky submits a copy of the
proposed regulation or other revisions
to EPA before conducting its public
hearing. EPA reviews this proposed
State action, and prepares a notice of
proposed rulemaking for publication in
the Federal Register within the same
general time frame as Kentucky’s public
comment period. After the
Commonwealth submits a final SIP
revision (including a response to public
comments raised during the
Commonwealth’s public participation
process) to EPA, the Agency will
prepare a final rulemaking notice. If the
Commonwealth’s final SIP submittal
contains changes which occur after
EPA’s notice of proposed rulemaking,
such changes must be described in
EPA’s final rulemaking action. If the
Commonwealth’s changes are
significant, then EPA must decide
whether it is appropriate to re-propose
the Commonwealth’s action.
II. What Authorities Apply To Moving
the Northern Kentucky I/M Program to
a Contingency Measure in the Kentucky
SIP?
Section 110(l) of the Clean Air Act
(i.e., ‘‘Act’’) states:
Each revision to an implementation plan
submitted by a State under this Act shall be
adopted by such State after reasonable notice
and public hearing. The Administrator shall
not approve a revision to a plan if the
revision would interfere with any applicable
requirement concerning attainment and
reasonable further progress (as defined in
section 171), or any other applicable
requirement of this Act.
The States’ obligation to comply with
each of the NAAQS is considered as
‘‘any applicable requirement(s)
concerning attainment.’’ A
demonstration is necessary to show that
this revision will not interfere with
attainment or maintenance of the
PO 00000
Frm 00065
Fmt 4702
Sfmt 4702
17031
NAAQS, including those for ozone, CO,
and PM2.5, or any other requirement of
the Act.
With respect to the 1-hour ozone
NAAQS, EPA redesignated the
Kentucky portion of the CincinnatiHamilton area to attainment for the 1hour ozone standard in a final action
published July 31, 2002 (67 FR 49600).
The Cincinnati-Hamilton moderate 1hour ozone nonattainment area
(Cincinnati-Hamilton area) includes the
Ohio Counties of Hamilton, Butler,
Clermont, and Warren, and the
Kentucky Counties of Boone, Campbell,
and Kenton. As part of its redesignation
to attainment for a NAAQS, the area
must have a plan to maintain the
standard, called a ‘‘maintenance plan.’’
Under section 175A(a) of the Act,
emission reduction programs in a
maintenance plan for a NAAQS must be
continued unless a demonstration is
made that the future, projected
emissions for the area, without credit for
reductions due to the emission
reduction program being removed,
remain at or below the baseline
attainment level of emissions identified
in the maintenance plan. If such a
demonstration is made, that program is
eligible for removal from the SIP.
However, section 175A(d) of the Act
requires that available contingency
measures in the maintenance plan
include all measures in the SIP for the
area before that area was redesignated to
attainment. Since the VET Program was
in the SIP prior to redesignation to
attainment for the 1-hour ozone
NAAQS, the VET Program must be
listed in the contingency portion of the
1-hour ozone maintenance plan as
required by section 175A(d). Kentucky
was able to demonstrate continued
maintenance of the 1-hour ozone
standard for the requisite timeframe
without taking credit for reductions
from the Northern Kentucky VET
Program, as summarized in section III
below.
In addition, provisions in EPA’s I/M
rule, set forth in 40 CFR 51.372(c) under
the heading ‘‘Redesignation requests,’’
apply to the Northern Kentucky VET
Program situation. These provisions
were published January 5, 1995, at 60
FR 1735. The provisions allow certain
areas seeking redesignation to submit
only the authority for an I/M program
rather than an implemented program in
satisfaction of the applicable I/M
requirements. Under these I/M rule
provisions, a basic I/M area (i.e., was
required to adopt a basic I/M program)
which has been redesignated to
attainment for the 1-hour ozone NAAQS
can convert the I/M program to a
contingency measure as part of the
E:\FR\FM\04APP1.SGM
04APP1
17032
Federal Register / Vol. 70, No. 63 / Monday, April 4, 2005 / Proposed Rules
area’s 1-hour ozone maintenance plan,
notwithstanding the new
antibacksliding provisions in EPA’s 8hour ozone implementation rule
published April 30, 2004 (69 FR 23858).
A basic I/M area which is designated
nonattainment for the 8-hour ozone
NAAQS, yet not required to have an
I/M program based on its 8-hour ozone
designation, continues to have the
option to move its I/M program to a
contingency measure as long as the 8hour ozone nonattainment area can
demonstrate that doing so will not
interfere with its ability to comply with
any NAAQS or any other applicable
Clean Air Act requirement pursuant to
section 110(l) of the Act. For further
details on the application of 8-hour
ozone anti-backsliding provisions to
basic I/M programs in 1-hour ozone
maintenance areas, please refer to the
May 12, 2004, EPA Memorandum from
Tom Helms, Group Leader, Ozone
Policy and Strategies Group, Office of
Air Quality Planning and Standards,
and Leila H. Cook, Group Leader, State
Measures and Conformity Group, Office
of Transportation and Air Quality, to the
Air Program Managers, the subject of
which is ‘‘1 Hour Ozone Maintenance
Plans Containing Basic I/M Programs.’’

III. What Is EPA’s Analysis of
Kentucky’s Demonstration of NonInterference With the 1-Hour Ozone
and CO NAAQS?
A. EPA’s Analysis of Kentucky’s
Demonstration of Non-Interference With
the 1-Hour Ozone NAAQS
The November 12, 2004, Kentucky
SIP revision seeking removal of the VET
Program includes an evaluation for the
1-hour ozone NAAQS of the potential
emission impacts associated with
increased emissions that would result
from removal of the Northern Kentucky
VET Program as an active control
measure in the SIP. For the 1-hour
ozone NAAQS, the submittal provides
VOC and NOX emission inventory data
for the Northern Kentucky portion (i.e.,
Boone, Campbell, and Kenton Counties)
of the Cincinnati-Hamilton MSA for
1996, the year the area met the 1-hour
ozone NAAQS, and projected emissions
through 2010. The emission inventory
data for the ‘‘Mobile’’ source category
are calculated using MOBILE6.2 because
this same model was used to determine
the emissions reductions from the VET
Program needing to be replaced.
MOBILE6.2 is a model which provides
estimates of emissions from onroad
mobile sources. The mobile source data
updated with MOBILE 6.2 are to replace
the MOBILE5a emissions data in the
currently approved Northern Kentucky
1-Hour Ozone Maintenance Plan, which
results in updated MVEBs for the year
2010 of 7.68 tons per summer day (tpsd)
VOC and 17.42 tpsd NOX.
In Tables 1 and 2 below, the emission
inventory projections for 2005, 2008,
and 2010 are updated to reflect the
changes proposed by the November 12,
2004, submittal, namely removal of the
VET Program as an active control
measure and application of two rules to
further control VOCs in the Northern
Kentucky area. The VOC and NOX
emission totals for this area include
emissions from the point, area, mobile,
and non-highway (or nonroad) source
categories. As shown in Tables 1 and 2
below, the projected, total VOC and
NOX emissions without the VET
Program for 2005, 2008, and 2010 for
the Northern Kentucky area all fall
below the 1996 attainment year
emission levels of 45.10 tpsd VOC and
74.13 tpsd NOX. For example, Table 1
shows the current 2005 total VOC
emissions projected for the area are
34.16 tpsd. By adding the predicted
increase of 0.78 tpsd VOC in 2005 due
to the closure of the VET Program, this
results in 34.94 tpsd of VOC in 2005,
which is below the 1996 attainment
level of 45.10 tpsd VOC. This same
analysis proves true when comparing
the VOC emissions in tpsd of 34.01 in
2008 and 34.40 in 2010 to the 1996
attainment level of 45.10, and when
comparing the NOX emissions in tpsd
for 2005, 2008, and 2010 of 69.13, 65.13,
and 64.06, respectively, to the 1996
attainment level of 74.13 tpsd. The area
does not exceed its 1-hour ozone
maintenance level of emissions, even
after removal of the VET Program. Thus,
the Northern Kentucky area
demonstrates continued maintenance of
the 1-hour ozone NAAQS without the
Northern Kentucky VET Program.

B. Updated MVEBs for 2010
In the November 12, 2004, submittal,
Kentucky notes that the MVEBs
established for the year 2010 for the
Kentucky portion of the CincinnatiHamilton MSA (i.e., the Northern
Kentucky area) are also updated using
MOBILE6.2. A MVEB is the projected
level of controlled emissions from the
transportation sector (mobile sources)
that is estimated in the SIP. The SIP
controls emissions through regulations,
for example, on fuels and exhaust levels
for cars. The MVEB concept is further
explained in the preamble to the
November 24, 1993, transportation
conformity rule (58 FR 62188). The
preamble also describes how to
establish the MVEB in the SIP and
revise the MVEB.
The 2010 MVEBs were originally
established by Kentucky and Ohio for
this area as a part of the 1-hour ozone
maintenance plan that was associated
with the redesignation of this area to
attainment of the 1-hour ozone NAAQS.
Subsequently, both Kentucky and Ohio
revised the 2010 MVEBs for this area,
and established individual State MVEBs
for their respective portions of the
Cincinnati 1-hour ozone maintenance
area. Kentucky’s revised 2010 MVEBs,
applicable only to Boone, Kenton and
Campbell counties in Kentucky, were
approved by EPA on May 30, 2003,
through final rulemaking (68 FR 104).
These MVEBs, which included an
allocation from the available safety
margin, were developed with the
MOBILE5 emissions factor model, and
are 7.02 tpsd of VOC and 17.33 tpsd of
NOX. The establishment of the
individual State MVEBs for these areas
allows each State to implement the
conformity requirements independent of
one another. Today’s action relates only
to revisions to the Kentucky 2010
MVEBs.
EPA is proposing to approve the
updated 2010 MVEBs of 7.68 tpsd VOC
and 17.42 tpsd NOX because the total
emissions from all sources in the
Northern Kentucky area remain below
the 1996 attainment levels, as depicted
in Tables 1 and 2 above. These revised
MVEBs were developed with the
MOBILE6.2 mobile emissions factor
model and do not include an allocation
from the available safety margin. Upon
final approval of these updated MVEBs,
the budgets will be used by the
Northern Kentucky area to determine
transportation conformity.

C. EPA’s Analysis of Kentucky’s
Demonstration of Non-Interference With
the CO NAAQS
The November 12, 2004, submittal
does not include a demonstration of
non-interference with the CO standard
to show that the CO increases expected
from closure of the VET Program will
not interfere with continued attainment
of the CO NAAQS in the Northern
Kentucky area. Because CO is one of the
applicable requirements of the Act,
Kentucky will need to include a
demonstration of non-interference for
CO in the final SIP submittal. In
Kentucky’s July 16, 2004, proposed SIP
revision, the Commonwealth provided
data showing that CO levels are
expected to increase by 12.5 tpsd in
2005 due to discontinuation of the VET
Program.
The Northern Kentucky area has
always been attainment for the CO
NAAQS, and CO monitoring data from
the years 1991–2001 show CO levels
trending downward. Specifically, in
1991, CO levels in Northern Kentucky
were 77 percent below the 1-hour and
46 percent below the 8-hour CO
standards. In contrast, monitored CO
levels in 2001 fell 93 percent below the
1-hour and 80 percent below the 8-hour
CO standards. Based on a preliminary
review of this data, EPA believes closure
of the VET Program will not interfere
with continued attainment of the CO
NAAQS in the Northern Kentucky area.
IV. What Is EPA’s Analysis of
Kentucky’s Demonstration of NonInterference With the 8-Hour Ozone
and Fine Particulate Matter NAAQS?
A. What Criteria Must Be Met?
EPA designated the Kentucky
Counties of Boone, Campbell, and
Kenton nonattainment for the 8-hour
ozone NAAQS on April 30, 2004 (69 FR
23858), effective June 15, 2004. EPA
designated these same counties
nonattainment for the PM2.5 NAAQS in
a final action published January 5, 2005
(70 FR 944), effective April 5, 2005. For
an area such as the Northern Kentucky
area that does not yet have an
attainment demonstration for the new 8hour ozone and PM2.5 NAAQS, EPA has
provided its interpretation of section
110(1) of the Clean Air Act in a May 11,
2004, letter from EPA to Louisville’s
Assistant County Attorney. (To view a
copy of this letter, go to the RME Web
site, https://docket.epa.gov/rmepub/,
enter the Docket ID for this action, R04–
OAR–2004–KY–0003, and click on the
appropriate Document ID.) A strict
interpretation of the requirement in
section 110(1) of the Clean Air Act
would allow EPA to approve a SIP
PO 00000
Frm 00067
Fmt 4702
Sfmt 4702
17033
revision removing a SIP requirement
only after determining, based on a
completed attainment demonstration,
that it would not interfere with
applicable requirements concerning
attainment and reasonable further
progress. However, EPA recognizes that
prior to the time areas are required to
submit attainment demonstrations for
the 8-hour ozone and PM2.5 NAAQS,
this strict interpretation could prevent
any changes to SIP control measures.
EPA does not believe this strict
interpretation is necessary or
appropriate.
Prior to the time that attainment
demonstrations are due for the 8-hour
ozone and PM2.5 standards, it is
unknown what suite of control
measures are needed for a given area to
attain these standards. During this
period, to demonstrate no interference
with any applicable NAAQS or
requirement of the Clean Air Act under
section 110(l), EPA believes it is
appropriate to allow States to substitute
equivalent emissions reductions to
compensate for the control measure
being moved from the active portion of
the SIP to the contingency provisions, as
long as actual emissions in the air are
not increased. EPA concluded that
preservation of the status quo air quality
during the time new attainment
demonstrations are being prepared will
prevent interference with the States’
obligations to develop timely attainment
demonstrations.
‘‘Equivalent’’ emissions reductions
mean reductions which are equal to or
greater than those reductions achieved
by the control measure to be removed
from the active portion of the SIP. To
show the compensating, emissions
reductions are equivalent, modeling or
adequate justification must be provided.
(EPA memorandum from John Calcagni,
Director, Air Quality Management
Division, to the Air Directors in EPA
Regions 1–10, September 4, 1992, pages
10 and 13.) As stated in the May 11,
2004, letter referenced earlier, the
compensating, equivalent reductions
must represent actual, new emissions
reductions achieved in a
contemporaneous time frame to the
termination of the existing SIP control
measure, in order to preserve the status
quo level of emissions in the air. In
addition to being contemporaneous, the
equivalent emissions reductions must
also be permanent, enforceable,
quantifiable, and surplus to be approved
into the SIP.

Federal Register / Vol. 70, No. 63 / Monday, April 4, 2005 / Proposed Rules
1. Contemporaneous
Kentucky Senate Joint Resolution 3
dated March 29, 2004, the closure of the
Northern Kentucky VET Program is
legislated to occur once EPA approves,
through rulemaking, a revision to the
Kentucky SIP incorporating
compensating, equivalent emissions
reductions to replace the VET Program.
(To view a copy of the Senate Joint
Resolution 3, please see Appendix A of
the November 12, 2004, submittal
available in EPA’s RME system.) As long
as closure of the VET Program occurs
within one year from the replacement
emissions reductions, these reductions
will be contemporaneous to the
emissions reductions from both rules,
401 KAR 59:185 and 401 KAR 59:760.
While ‘‘contemporaneous’’ is not
explicitly defined in the Clean Air Act,
a reasonable interpretation is to enact
the compensating, equivalent emissions
reductions within one year (prior to or
following) the cessation of the
substituted control measure. The State
effective date of revisions to regulation
401 KAR 59:185 is January 4, 2005. The
State effective date of 401 KAR 59:760
is likely to occur, at the latest, during
the March-April 2005 timeframe,
contingent on the typical schedule of
Kentucky’s rulemaking process, with
the emergency version of this rule
already in effect as of November 15,
2004. The November 12, 2004, submittal
requests two different effective dates for
the VET Program’s closure. Kentucky
will clarify in the final submittal the
correct date requested. The actual
effective date is contingent upon EPA’s
final action. In accordance with
2. Equivalent
The VET Program reduces emissions
of VOC, NOX, and CO. VOC and NOX
are contributors (‘‘precursors’’) to the
formation of ground-level ozone and
fine particulate matter. Thus, the
increase in VOC and NOX need to be
offset with equivalent (or greater)
emissions reductions from another
control measure(s) in order to
demonstrate non-interference with the
8-hour ozone and PM2.5 NAAQS.
Substitute CO emissions reductions are
not needed for this demonstration
because the area is attaining the CO
NAAQS and CO levels in the area are
well below the standard, as noted in
section III.C. of this document. It is
unlikely that removing the VET Program
will interfere with the area’s ability to
continue to attain the CO NAAQS.
a. Selection of the Year 2005 To
Estimate Emission Increases From
B. What Is EPA’s Analysis of Whether
the Proposed Reductions Meet the
Criteria of Contemporaneous,
Equivalent, Quantifiable, Permanent,
Enforceable, and Surplus?
The November 12, 2004, submittal
proposes equivalent VOC emissions
reductions for the Northern Kentucky
VET Program from two Kentucky rules.
The following is a description of how
the proposed VOC emissions reductions
from two Kentucky rules, 401 KAR
59:185 and 401 KAR 59:760, meet the
six criteria of contemporaneous,
equivalent (or greater), permanent,
enforceable, quantifiable, and surplus.
Closure of the Northern Kentucky VET
Program. To demonstrate that the VOC
emissions reductions from 401 KAR
59:185 and 401 KAR 59:760 provide the
equivalent benefit of the VOC and NOX
emissions reductions achieved by the
VET Program, Kentucky first identified
the expected increases in emissions due
to closure of the program for the years
2005, 2008, and 2010. As shown in
Table 3 below, VOC and NOX emissions
from onroad mobile sources are
expected to increase in 2005 by 0.78
tpsd and 0.29 tpsd, respectively, due to
closure of the Northern Kentucky VET
Program. In 2008 and 2010, expected
VOC and NOX reductions from the VET
Program decline. In particular, NOX
reductions are predicted to be 0.02 tpsd
in 2008 and 0.09 tpsd for 2010. Thus,
the year 2005 provides the greatest
number of VET Program emissions that
need to be replaced. For these reasons,
EPA believes that analyzing emissions
for 2005 is conservative, and represents
the greatest impact on air quality from
the Program’s closure beginning in
2005, when emissions from the loss of
the Program would first impact the area.
Kentucky used MOBILE6.2, EPA’s
latest version of the mobile model for
estimating onroad mobile source
emissions, to develop the onroad mobile
emission estimates for the Northern
Kentucky area. The MOBILE6.2-based
emissions are proposed to replace the
Mobile5a-generated emissions in the
current, approved 1-hour ozone
maintenance plan for the Northern
Kentucky area.

Program. To determine the equivalent
number of VOCs to replace 0.78 tpsd
VOC and 0.29 tpsd NOX emissions
reductions predicted in 2005 from the
VET Program, Kentucky converted the
0.29 tpsd of NOX into VOC using an
equation developed in accordance with
the August 5, 1994, EPA memorandum,
‘‘Clarification of Policy for Nitrogen
Oxides (NOX) Substitution,’’ from John
Seitz. This memorandum pertains to
EPA’s ‘‘NOX Substitution Guidance’’

(December 1993). The guidance
acknowledges that controlling only
VOCs may not be the most effective
approach in all areas for attaining the
ozone standard, and allows for
substitution of NOX for VOC emissions
reductions required for Reasonable
Further Progress, contingent upon
approval by EPA. The 1994
memorandum further clarifies that NOX
for VOC substitution is a viable
approach prior to completing modeling
to support an area’s attainment
demonstration. Using the principles of

will similarly allow substitution of VOC
for NOX emissions reductions on a

Furthermore, the most recent

that although a NOX control strategy

would be most effective for reducing
regional scale ozone transport, VOC
reductions are most effective in more
dense urbanized areas. The Kentucky
Counties of Boone, Campbell, and
Kenton are in the Cincinnati-Hamilton
MSA adjacent to the highly populated
Ohio Counties of Hamilton and
Clermont.
To determine the amount of VOC that
will provide equivalent ozone reduction
benefits as the 0.29 tpsd of NOX,
Kentucky used the following equation
in accordance with EPA guidance: (NOX
increase due to closure of the VET
Program)/(Total NOX Emissions for the
Northern Kentucky Area) × (Total VOC
Emissions for the Northern Kentucky
Area) = Equivalent VOC emissions
reductions required. This equation
incorporates calculation of the VOC/
NOX ratio, which determines what a one
percent reduction in VOC is equivalent
to, in tpsd, for a one percent reduction
in NOX. This ratio is based upon EPA’s
NOX Substitution Guidance (December
1993). To calculate the VOC/NOX ratio,
the area’s total VOC emissions are
divided by the area’s total NOX
emissions from all source categories for
a given year. For example, the 2005
VOC/NOX ratio is: (32.56 tpsd VOC)/
(64.77 tpsd NOX) = (1 percent VOC
reduction)/(1 percent NOX reduction) =
0.50 tpsd VOC/1.0 tpsd NOX. Thus, to
reduce 1.0 tpsd of NOX, 0.50 tpsd of
VOC is required to be reduced. Using
this same calculation, the ratios for 2008
and 2010 are 0.52 tpsd VOC/1.0 tpsd
NOX and 0.53 tpsd VOC/1.0 tpsd NOX,
respectively. In the 2005 example, the
VOC/NOX ratio is then applied as
follows to solve for ‘‘X’’: 0.50 tpsd VOC/
1.0 tpsd NOX = X tpsd VOC/0.29 tpsd
NOX. For 2005, ‘‘X’’ equals 0.145 or,
with rounding, 0.15 tpsd of VOC must
be reduced to be equivalent to a 0.29
tpsd reduction of NOX. Similar
calculations for 2008 and 2010 show
that the equivalent amount of VOC
emissions reductions needed to replace
the 0.29 tpsd NOX are 0.151 tpsd and
0.154 tpsd, respectively, which both
round to 0.15 tpsd VOC. This analysis
shows that the year used to develop the
VOC/NOX ratio does not alter, after
rounding, the resulting amount of 0.15
tpsd VOC-equivalent for 0.29 tpsd of
NOX.
In the November 2004 submittal,
Kentucky’s methodology applied total
VOC and NOX emission data for the year
2010 in the ‘‘VOC Equivalent
Emissions’’ equation above because this
provides the greatest number of VOCequivalent emissions to replace.
VerDate jul<14>2003
15:01 Apr 01, 2005
Jkt 205001
Kentucky computed the VOC-equivalent
to the 0.29 tpsd of NOX emissions
reductions expected in 2005 from the
VET Program as follows: (0.29 tpsd
NOX)/(63.77 tpsd NOX) × (34.05 tpsd
VOC) = 0.1548 or, with rounding, 0.15
tpsd VOC. In the final submittal,
Kentucky will clarify references to the
VOC/NOX ratio in the November 2004
proposed revision to show how the
ratios derived in Appendices B and E
are used in the ‘‘VOC Equivalent
Emissions’’ equation above.
c. Equivalent Emissions Reductions
From Two Kentucky Rules. To calculate
the total number of VOC emissions
reductions needed to replace the VET
Program, Kentucky added the 0.15 tpsd
VOC-equivalent of 0.29 tpsd NOX to the
0.78 tpsd VOC emissions increase
expected in 2005 from closure of the
program, yielding 0.93 tpsd VOC (i.e.,
0.15 + 0.78). Thus, 0.93 tpsd of VOC
emissions reductions are needed to
replace the VET Program.
As explained in the following section,
‘‘4. Quantifiable,’’ revisions to rule 401
KAR 59:185 and new rule 401 KAR
59:760 are expected to reduce VOCs in
2005 by 0.71 tpsd and 0.27 tpsd,
respectively, yielding a total of 0.98 tpsd
VOC emissions reductions (i.e., 0.71 +
0.27 = 0.98) from these rules. These
emissions reductions exceed the 0.93
tpsd VOCs needed to replace the VET
Program by 0.05 tpsd (i.e., 0.98–0.93 =
0.05).
Therefore, based on this conservative
equivalency analysis, the proposed 0.98
tpsd of VOC reductions from the two
Kentucky rules are equivalent, in terms
of reduced ozone formation benefits, to
the VOC and NOX reductions from the
VET Program. In addition, VOC and
NOX, the relevant pollutants controlled
by the VET Program, are contributing
precursors to the formation of PM2.5 and
thus, EPA concludes that these
equivalent reductions also demonstrate
non-interference with the PM2.5
NAAQS.
3. Quantifiable
The November 12, 2004, submittal
shows that in 2005, 0.71 tpsd of VOC
will be reduced through the revisions to
rule 401 KAR 59:185, and 0.27 tpsd of
VOCs will be reduced through rule 401
KAR 59:760. The emissions reductions
meet the criterion for quantifiable, as
the VOC emissions reductions may be
calculated as follows.
The rule revisions to 401 KAR 59:185
establish a vapor pressure limit for
solvents used in cold cleaning
degreasing operations in the Northern
PO 00000
Frm 00069
Fmt 4702
Sfmt 4702
17035
Kentucky Counties of Boone, Campbell,
and Kenton. Section 4(3)(a) of the
regulation requires that vendors provide
in these counties only solvents with a
vapor pressure at or below 1.0
millimeters (mm) of mercury measured
at 20 degrees Celsius for solvents sold
in units greater than five gallons for use
in cold cleaners. Section 4(3)(b)
prohibits operations of a cold cleaner
using a solvent exceeding the vapor
pressure limit described for section
4(3)(a). In addition, section 4(4) of the
regulation requires users to keep records
of their solvent purchases.
To determine the amount of VOC
reductions from revisions to 401 KAR
59:185 affecting the Northern Kentucky
counties, the projected 2005 cold
cleaning degreasing emissions (in tpsd)
for these counties are multiplied by 67
percent, which is the control efficiency
(CE) of the rule, and 80 percent, which
is the rule effectiveness (RE) factor. The
CE provides an estimate of the percent
VOC reduction expected from lowering
the vapor pressure limit in the rule as
described above. The 67 percent CE has
been used in similar cold cleaning
degreasing regulations in the States of
Indiana, Illinois, and Maryland. The RE
factor of 80 percent is an EPA estimate
of the effectiveness of this type of rule.
The results of this calculation provide
the 2005 cold cleaning degreasing
estimated emissions reductions. For
example, in Boone County, 0.32 tpsd of
VOC emissions are projected for 2005
from cold cleaning degreasing. This
2005 cold cleaning degreasing
projection was derived from identifying
the percent contribution to the 2005
VOC projections from the total solvent
degreasing area source category listed in
Appendix I of the Northern Kentucky 1Hour Ozone Maintenance Plan
approved by EPA into the Kentucky SIP.
Using EPA emission factors, Kentucky
determined that cold cleaning
degreasing VOC emissions contribute 84
percent to the total solvent degreasing
emission projection of 0.38 tpsd VOC,
i.e., (0.38 tpsd VOC) × (84 percent) =
0.32 tpsd VOC. Using the multipliers
described above for the Boone County
example, (0.32 tpsd VOC) × (67 percent
CE) × (80 percent RE) = 0.17 tpsd VOC
cold cleaning degreasing emissions are
expected to be reduced in 2005 from the
rule revisions. Table 4 below presents
the VOC reductions expected for Boone,
Campbell, and Kenton Counties from
the revisions to 401 KAR 59:185, which
total 0.71 tpsd VOC.

Kentucky rules, 401 KAR 59:185 and
401 KAR 59:760, are made permanent
through Kentucky’s rulemaking process.
Once State effective, these regulations
have the full force of a law and establish
obligatory requirements applicable to
affected groups. EPA’s approval of the
final SIP revision will incorporate
revisions to 401 KAR 59:185 and new
rule 59:760 into the federally
enforceable Kentucky SIP. EPA is not
taking action on emergency rule, 401
KAR 59:760E, included in the
November 12, 2004, submittal because
the rule has an expiration date under
Kentucky Revised Statute 13A.190, and
thus, is not permanent. Since the

emergency rule are not included in the
calculation of equivalent emissions

5. Enforceable
The emissions reductions are
enforceable by the Commonwealth of
Kentucky as of the State effective date
of these regulations. Upon final
approval into the Kentucky SIP, revised
rule 401 KAR 59:185 and new rule
59:760 will be Federally enforceable by
the EPA, as of the effective date of EPA’s
final rulemaking.
6. Surplus
The VOC emissions reductions from
Kentucky’s two rules are surplus for two
reasons. The emissions reductions go
beyond the reductions already required
in the Kentucky SIP, and the reductions
are not from a Federal Control Measure
that would occur without any State or
local action. Specifically, the 0.71 tpsd
of VOC emissions reductions from
revisions to 401 KAR 59:185 are due to
new provisions created in sections 4(3)
and 4(4) which prohibit the sale and use
of solvents with vapor pressure limits
exceeding that specified in the
regulation. Rule 401 KAR 59:760 is a

technology at mobile equipment
refinishing operations in Northern
Kentucky.
V. What Is EPA’s Proposed Action?
EPA is proposing to move 401 KAR
65:010, ‘‘Vehicle emission control
programs’’ from the active control
measure portion of the Kentucky SIP to
the contingency measures section of the
Northern Kentucky 1-Hour Ozone
Maintenance Plan. EPA is also
proposing to approve revisions to
Kentucky rule 401 KAR 59:185, ‘‘New
solvent metal cleaning equipment’’ and
the addition of new rule 401 KAR
59:760, ‘‘Commercial Motor Vehicle and
Mobile Equipment Refinishing
Operations,’’ into the Kentucky SIP.
Finally, EPA is proposing to approve
updated mobile source category
emission projections using MOBILE6.2,
with updated, subarea MVEBs of 7.68
tpsd VOC and 17.42 tpsd NOX for the
year 2010. EPA’s proposed approval is
contingent upon Kentucky addressing
E:\FR\FM\04APP1.SGM
04APP1
Federal Register / Vol. 70, No. 63 / Monday, April 4, 2005 / Proposed Rules
the requested clarifications in EPA’s
December 29, 2004, comment letter on
this proposed SIP revision. Kentucky
must include a demonstration of noninterference with the CO NAAQS, as
demonstrated by very low levels of
ambient CO—well below the NAAQS—
and the fact that the area is in
attainment of the CO NAAQS. Kentucky
must also clarify references to the VOC/
NOX ratio and modify subsection (1)(j)
of section 3, ‘‘Operating requirements,’’
of 401 KAR 59:760. This subsection uses
language which mirrors that of the
Ozone Transport Commission model
rule. However, to be consistent with
current Agency policy, this language
needs to be revised to include some
form of public review for determining
other coating application methods
which achieve emissions reductions
equivalent to high volume low pressure
or electrostatic spray application
methods. In the current language
proposed, the Kentucky Cabinet makes
this determination.
VI. Statutory and Executive Order
Reviews
Under Executive Order 12866 (58 FR
51735, October 4, 1993), this proposed
action is not a ‘‘significant regulatory
action’’ and therefore is not subject to
review by the Office of Management and
Budget. For this reason, this action is
also not subject to Executive Order
13211, ‘‘Actions Concerning Regulations
That Significantly Affect Energy Supply,
Distribution, or Use’’ (66 FR 28355, May
22, 2001). This proposed action merely
proposes to approve State law as
meeting Federal requirements and
imposes no additional requirements
beyond those imposed by State law.
Accordingly, the Administrator certifies
that this proposed rule will not have a
significant economic impact on a
substantial number of small entities
under the Regulatory Flexibility Act (5
U.S.C. 601 et seq.). Because this rule
proposes to approve pre-existing
requirements under State law and does
not impose any additional enforceable
duty beyond that required by State law,
it does not contain any unfunded
mandate or significantly or uniquely
affect small governments, as described
in the Unfunded Mandates Reform Act
of 1995 (Public Law 104–4).
This proposed rule also does not have
tribal implications because it will not
have a substantial direct effect on one or
more Indian tribes, on the relationship
between the Federal Government and
Indian tribes, or on the distribution of
power and responsibilities between the
Federal Government and Indian tribes,
as specified by Executive Order 13175
(65 FR 67249, November 9, 2000). This
VerDate jul<14>2003
15:01 Apr 01, 2005
Jkt 205001
action also does not have Federalism
implications because it does not have
substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132 (64 FR 43255,
August 10, 1999). This action merely
proposes to approve a State rule
implementing a Federal standard, and
does not alter the relationship or the
distribution of power and
responsibilities established in the Clean
Air Act. This proposed rule also is not
subject to Executive Order 13045
‘‘Protection of Children from
Environmental Health Risks and Safety
Risks’’ (62 FR 19885, April 23, 1997),
because it is not economically
significant.
In reviewing SIP submissions, EPA’s
role is to approve State choices,
provided that they meet the criteria of
the Clean Air Act. In this context, in the
absence of a prior existing requirement
for the State to use voluntary consensus
standards (VCS), EPA has no authority
to disapprove a SIP submission for
failure to use VCS. It would thus be
inconsistent with applicable law for
EPA, when it reviews a SIP submission,
to use VCS in place of a SIP submission
that otherwise satisfies the provisions of
the Clean Air Act. Thus, the
requirements of section 12(d) of the
National Technology Transfer and
Advancement Act of 1995 (15 U.S.C.
272 note) do not apply. This proposed
rule does not impose an information
collection burden under the provisions
of the Paperwork Reduction Act of 1995
(44 U.S.C. 3501 et seq.).

AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to approve four related revisions to the
Kentucky State Implementation Plan (SIP) submitted by the Commonwealth
of Kentucky on November 12, 2004. These revisions affect the Northern
Kentucky area, which is comprised of the Kentucky Counties of Boone,
Campbell, and Kenton, and is part of the Cincinnati-Hamilton
Metropolitan Statistical Area. EPA is proposing to approve the movement
of the regulation underlying the Northern Kentucky inspection and
maintenance (I/M) program from the active portion of the Kentucky SIP
to the contingency measures section of the Northern Kentucky 1-Hour
Ozone Maintenance Plan. EPA is also proposing to approve revisions to a
Kentucky rule which provides for the control of volatile organic
compounds from new solvent metal cleaning equipment. Further, EPA
proposes to add a new rule to the Kentucky SIP affecting commercial
motor vehicle and mobile equipment refinishing operations in Northern
Kentucky. Finally, EPA is proposing to approve updated mobile source
category emission projections using MOBILE6.2, with updated, subarea
motor vehicle emission budgets (MVEBs) for the year 2010. EPA's final
approval is contingent upon Kentucky making some clarifications in the
final SIP submittal.

I. What Changes to the Kentucky SIP Were Submitted for EPA Approval?
In response to a Kentucky Legislative action signed by the Governor
on April 9, 2004, Kentucky submitted to EPA a proposed revision to the
Kentucky SIP on November 12, 2004, for parallel processing. This
revision affects regulation 401 KAR 65:010, ``Vehicle emission control
programs,'' which is a SIP-approved regulation underlying the Northern
Kentucky I/M program, also known as the Northern Kentucky Vehicle
Emissions Testing (VET) Program. Kentucky has requested to move the VET
Program regulation from the active control measures portion of the SIP
to the contingency measures portion of the Northern Kentucky 1-Hour
Ozone Maintenance Plan, which is part of the Kentucky SIP. The Northern
Kentucky VET Program is a basic I/M program that includes on-board
diagnostics (i.e., OBD) and results in emissions reductions of nitrogen
oxides (NOX), volatile organic compounds (VOC), and carbon
monoxide (CO). The VET Program began testing vehicles in Boone,
Campbell, and Kenton Counties in September 1999, to help meet
nonattainment area requirements for the ozone NAAQS effective at the
time.
The Northern Kentucky area is comprised of the Kentucky Counties of
Boone, Campbell, and Kenton, and is part of the Cincinnati-Hamilton
Metropolitan Statistical Area (MSA). Presently, Boone, Campbell, and
Kenton Counties comprise the Northern Kentucky portion of the
Cincinnati 1-Hour Ozone Maintenance Area. This maintenance status means
these counties were formerly designated nonattainment for the 1-hour
ozone standard, are now attaining this standard, and have since been
redesignated to attainment for the 1-hour ozone standard effective July
5, 2000 (July 31, 2002, 67 FR 49600). This area was previously
classified as a moderate ozone nonattainment area. As such, the area
was required to
[[Page 17031]]
implement a basic I/M program under section 182(b)(4) of the Clean Air
Act.
Kentucky's November 12, 2004, draft SIP submittal proposes to
implement new emission reductions to compensate for the NOX
and VOC emission increases resulting from removing the Northern
Kentucky VET Program as an active control measure in the SIP. To
demonstrate non-interference with applicable requirements of the Act
through replacement emissions reductions, the compensating emissions
reductions must be equivalent to or greater than those achieved with
the VET Program. Equivalent emissions reductions are needed to replace
an anticipated increase of 0.78 tons per summer day (tpsd) of VOC and
0.29 tpsd of NOX in the year 2005 due to closure of the VET
Program. These replacement VOC and NOX emissions reductions
must also occur in a time period contemporaneous to the VET Program's
closure, as explained further in section IV. The VOC and NOX
replacement emissions reductions are needed to support a demonstration
of non-interference with the 8-hour ozone and fine particulate matter
(PM2.5) NAAQS.
The VET Program also reduces CO emissions. In response to EPA
comments on the November proposal, Kentucky will also include a
demonstration of non-interference with the CO NAAQS in the final SIP
submittal to address the CO emission increases due to discontinuation
of the VET Program.
The November 12, 2004, submittal proposes VOC emissions reductions
from two Kentucky rules. The revisions to Kentucky rule 401 KAR 59:185,
``New solvent metal cleaning equipment,'' requires the use of VOC
solvents with lower vapor pressures in batch cold cleaning machines
used in specified facilities located in the Northern Kentucky Counties
of Boone, Campbell, and Kenton. These revisions were originally
submitted to EPA on July 16, 2004. Kentucky's public hearing on the
proposed amendments to 401 KAR 59:185 was held August 25, 2004, with
written comments due by August 31, 2004. In a letter dated August 31,
2004, EPA concurred with the revisions and the analysis for estimating
VOC emissions reductions from these rule changes. (A copy of this
letter is located on the RME Web site under the Docket ID, R04-OAR-
2004-KY-0003.) The November 12, 2004, submittal, which replaces the
July 16, 2004, proposed SIP revision, also proposes to add a new rule,
401 KAR 59:760, ``Commercial Motor Vehicle and Mobile Equipment
Refinishing Operations,'' to the Kentucky SIP. This new regulation
requires the use of high transfer efficiency application techniques at
auto body repair and refinishing operations, and prescribes operating
procedures to minimize the emissions of VOCs. The Commonwealth also
enacted and included in the November 12, 2004, submittal an emergency
version of rule 401 KAR 59:760, i.e., 401 KAR 59:760E, with a State
effective date of November 15, 2004, and a compliance date of February
1, 2005. EPA is not taking action on this emergency regulation, 401 KAR
59:760E. The public hearing on rule 401 KAR 59:760 and movement of the
VET Program to the contingency measures list was held on January 4,
2005.
Under the parallel processing procedure, the Commonwealth of
Kentucky submits a copy of the proposed regulation or other revisions
to EPA before conducting its public hearing. EPA reviews this proposed
State action, and prepares a notice of proposed rulemaking for
publication in the Federal Register within the same general time frame
as Kentucky's public comment period. After the Commonwealth submits a
final SIP revision (including a response to public comments raised
during the Commonwealth's public participation process) to EPA, the
Agency will prepare a final rulemaking notice. If the Commonwealth's
final SIP submittal contains changes which occur after EPA's notice of
proposed rulemaking, such changes must be described in EPA's final
rulemaking action. If the Commonwealth's changes are significant, then
EPA must decide whether it is appropriate to re-propose the
Commonwealth's action.
II. What Authorities Apply To Moving the Northern Kentucky I/M Program
to a Contingency Measure in the Kentucky SIP?
Section 110(l) of the Clean Air Act (i.e., ``Act'') states:
Each revision to an implementation plan submitted by a State
under this Act shall be adopted by such State after reasonable
notice and public hearing. The Administrator shall not approve a
revision to a plan if the revision would interfere with any
applicable requirement concerning attainment and reasonable further
progress (as defined in section 171), or any other applicable
requirement of this Act.
The States' obligation to comply with each of the NAAQS is
considered as ``any applicable requirement(s) concerning attainment.''
A demonstration is necessary to show that this revision will not
interfere with attainment or maintenance of the NAAQS, including those
for ozone, CO, and PM2.5, or any other requirement of the
Act.
With respect to the 1-hour ozone NAAQS, EPA redesignated the
Kentucky portion of the Cincinnati-Hamilton area to attainment for the
1-hour ozone standard in a final action published July 31, 2002 (67 FR
49600). The Cincinnati-Hamilton moderate 1-hour ozone nonattainment
area (Cincinnati-Hamilton area) includes the Ohio Counties of Hamilton,
Butler, Clermont, and Warren, and the Kentucky Counties of Boone,
Campbell, and Kenton. As part of its redesignation to attainment for a
NAAQS, the area must have a plan to maintain the standard, called a
``maintenance plan.'' Under section 175A(a) of the Act, emission
reduction programs in a maintenance plan for a NAAQS must be continued
unless a demonstration is made that the future, projected emissions for
the area, without credit for reductions due to the emission reduction
program being removed, remain at or below the baseline attainment level
of emissions identified in the maintenance plan. If such a
demonstration is made, that program is eligible for removal from the
SIP. However, section 175A(d) of the Act requires that available
contingency measures in the maintenance plan include all measures in
the SIP for the area before that area was redesignated to attainment.
Since the VET Program was in the SIP prior to redesignation to
attainment for the 1-hour ozone NAAQS, the VET Program must be listed
in the contingency portion of the 1-hour ozone maintenance plan as
required by section 175A(d). Kentucky was able to demonstrate continued
maintenance of the 1-hour ozone standard for the requisite timeframe
without taking credit for reductions from the Northern Kentucky VET
Program, as summarized in section III below.
In addition, provisions in EPA's I/M rule, set forth in 40 CFR
51.372(c) under the heading ``Redesignation requests,'' apply to the
Northern Kentucky VET Program situation. These provisions were
published January 5, 1995, at 60 FR 1735. The provisions allow certain
areas seeking redesignation to submit only the authority for an I/M
program rather than an implemented program in satisfaction of the
applicable I/M requirements. Under these I/M rule provisions, a basic
I/M area (i.e., was required to adopt a basic I/M program) which has
been redesignated to attainment for the 1-hour ozone NAAQS can convert
the I/M program to a contingency measure as part of the
[[Page 17032]]
area's 1-hour ozone maintenance plan, notwithstanding the new
antibacksliding provisions in EPA's 8-hour ozone implementation rule
published April 30, 2004 (69 FR 23858). A basic I/M area which is
designated nonattainment for the 8-hour ozone NAAQS, yet not required
to have an I/M program based on its 8-hour ozone designation, continues
to have the option to move its I/M program to a contingency measure as
long as the 8-hour ozone nonattainment area can demonstrate that doing
so will not interfere with its ability to comply with any NAAQS or any
other applicable Clean Air Act requirement pursuant to section 110(l)
of the Act. For further details on the application of 8-hour ozone
anti-backsliding provisions to basic I/M programs in 1-hour ozone
maintenance areas, please refer to the May 12, 2004, EPA Memorandum
from Tom Helms, Group Leader, Ozone Policy and Strategies Group, Office
of Air Quality Planning and Standards, and Leila H. Cook, Group Leader,
State Measures and Conformity Group, Office of Transportation and Air
Quality, to the Air Program Managers, the subject of which is ``1 Hour
Ozone Maintenance Plans Containing Basic I/M Programs.'' A copy of this
memorandum may be obtained at https://www.epa.gov/ttn/oarpg/t1pgm.html
under the file date ``5-12-04.''
III. What Is EPA's Analysis of Kentucky's Demonstration of Non-
Interference With the 1-Hour Ozone and CO NAAQS?
A. EPA's Analysis of Kentucky's Demonstration of Non-Interference With
the 1-Hour Ozone NAAQS
The November 12, 2004, Kentucky SIP revision seeking removal of the
VET Program includes an evaluation for the 1-hour ozone NAAQS of the
potential emission impacts associated with increased emissions that
would result from removal of the Northern Kentucky VET Program as an
active control measure in the SIP. For the 1-hour ozone NAAQS, the
submittal provides VOC and NOX emission inventory data for
the Northern Kentucky portion (i.e., Boone, Campbell, and Kenton
Counties) of the Cincinnati-Hamilton MSA for 1996, the year the area
met the 1-hour ozone NAAQS, and projected emissions through 2010. The
emission inventory data for the ``Mobile'' source category are
calculated using MOBILE6.2 because this same model was used to
determine the emissions reductions from the VET Program needing to be
replaced. MOBILE6.2 is a model which provides estimates of emissions
from onroad mobile sources. The mobile source data updated with MOBILE
6.2 are to replace the MOBILE5a emissions data in the currently
approved Northern Kentucky 1-Hour Ozone Maintenance Plan, which results
in updated MVEBs for the year 2010 of 7.68 tons per summer day (tpsd)
VOC and 17.42 tpsd NOX.
In Tables 1 and 2 below, the emission inventory projections for
2005, 2008, and 2010 are updated to reflect the changes proposed by the
November 12, 2004, submittal, namely removal of the VET Program as an
active control measure and application of two rules to further control
VOCs in the Northern Kentucky area. The VOC and NOX emission
totals for this area include emissions from the point, area, mobile,
and non-highway (or nonroad) source categories. As shown in Tables 1
and 2 below, the projected, total VOC and NOX emissions
without the VET Program for 2005, 2008, and 2010 for the Northern
Kentucky area all fall below the 1996 attainment year emission levels
of 45.10 tpsd VOC and 74.13 tpsd NOX. For example, Table 1
shows the current 2005 total VOC emissions projected for the area are
34.16 tpsd. By adding the predicted increase of 0.78 tpsd VOC in 2005
due to the closure of the VET Program, this results in 34.94 tpsd of
VOC in 2005, which is below the 1996 attainment level of 45.10 tpsd
VOC. This same analysis proves true when comparing the VOC emissions in
tpsd of 34.01 in 2008 and 34.40 in 2010 to the 1996 attainment level of
45.10, and when comparing the NOX emissions in tpsd for
2005, 2008, and 2010 of 69.13, 65.13, and 64.06, respectively, to the
1996 attainment level of 74.13 tpsd. The area does not exceed its 1-
hour ozone maintenance level of emissions, even after removal of the
VET Program. Thus, the Northern Kentucky area demonstrates continued
maintenance of the 1-hour ozone NAAQS without the Northern Kentucky VET
Program.

B. Updated MVEBs for 2010
In the November 12, 2004, submittal, Kentucky notes that the MVEBs
established for the year 2010 for the Kentucky portion of the
Cincinnati-Hamilton MSA (i.e., the Northern Kentucky area) are also
updated using MOBILE6.2. A MVEB is the projected level of controlled
emissions from the transportation sector (mobile sources) that is
estimated in the SIP. The SIP controls emissions through regulations,
for example, on fuels and exhaust levels for cars. The MVEB concept is
further explained in the preamble to the November 24, 1993,
transportation conformity rule (58 FR 62188). The preamble also
describes how to establish the MVEB in the SIP and revise the MVEB.
The 2010 MVEBs were originally established by Kentucky and Ohio for
this area as a part of the 1-hour ozone maintenance plan that was
associated with the redesignation of this area to attainment of the 1-
hour ozone NAAQS. Subsequently, both Kentucky and Ohio revised the 2010
MVEBs for this area, and established individual State MVEBs for their
respective portions of the Cincinnati 1-hour ozone maintenance area.
Kentucky's revised 2010 MVEBs, applicable only to Boone, Kenton and
Campbell counties in Kentucky, were approved by EPA on May 30, 2003,
through final rulemaking (68 FR 104). These MVEBs, which included an
allocation from the available safety margin, were developed with the
MOBILE5 emissions factor model, and are 7.02 tpsd of VOC and 17.33 tpsd
of NOX. The establishment of the individual State MVEBs for
these areas allows each State to implement the conformity requirements
independent of one another. Today's action relates only to revisions to
the Kentucky 2010 MVEBs.
EPA is proposing to approve the updated 2010 MVEBs of 7.68 tpsd VOC
and 17.42 tpsd NOX because the total emissions from all
sources in the Northern Kentucky area remain below the 1996 attainment
levels, as depicted in Tables 1 and 2 above. These revised MVEBs were
developed with the MOBILE6.2 mobile emissions factor model and do not
include an allocation from the available safety margin. Upon final
approval of these updated MVEBs, the budgets will be used by the
Northern Kentucky area to determine transportation conformity.
C. EPA's Analysis of Kentucky's Demonstration of Non-Interference With
the CO NAAQS
The November 12, 2004, submittal does not include a demonstration
of non-interference with the CO standard to show that the CO increases
expected from closure of the VET Program will not interfere with
continued attainment of the CO NAAQS in the Northern Kentucky area.
Because CO is one of the applicable requirements of the Act, Kentucky
will need to include a demonstration of non-interference for CO in the
final SIP submittal. In Kentucky's July 16, 2004, proposed SIP
revision, the Commonwealth provided data showing that CO levels are
expected to increase by 12.5 tpsd in 2005 due to discontinuation of the
VET Program.
The Northern Kentucky area has always been attainment for the CO
NAAQS, and CO monitoring data from the years 1991-2001 show CO levels
trending downward. Specifically, in 1991, CO levels in Northern
Kentucky were 77 percent below the 1-hour and 46 percent below the 8-
hour CO standards. In contrast, monitored CO levels in 2001 fell 93
percent below the 1-hour and 80 percent below the 8-hour CO standards.
Based on a preliminary review of this data, EPA believes closure of the
VET Program will not interfere with continued attainment of the CO
NAAQS in the Northern Kentucky area.
IV. What Is EPA's Analysis of Kentucky's Demonstration of Non-
Interference With the 8-Hour Ozone and Fine Particulate Matter NAAQS?
A. What Criteria Must Be Met?
EPA designated the Kentucky Counties of Boone, Campbell, and Kenton
nonattainment for the 8-hour ozone NAAQS on April 30, 2004 (69 FR
23858), effective June 15, 2004. EPA designated these same counties
nonattainment for the PM2.5 NAAQS in a final action
published January 5, 2005 (70 FR 944), effective April 5, 2005. For an
area such as the Northern Kentucky area that does not yet have an
attainment demonstration for the new 8-hour ozone and PM2.5
NAAQS, EPA has provided its interpretation of section 110(1) of the
Clean Air Act in a May 11, 2004, letter from EPA to Louisville's
Assistant County Attorney. (To view a copy of this letter, go to the
RME Web site, https://docket.epa.gov/rmepub/, enter the Docket ID for
this action, R04-OAR-2004-KY-0003, and click on the appropriate
Document ID.) A strict interpretation of the requirement in section
110(1) of the Clean Air Act would allow EPA to approve a SIP revision
removing a SIP requirement only after determining, based on a completed
attainment demonstration, that it would not interfere with applicable
requirements concerning attainment and reasonable further progress.
However, EPA recognizes that prior to the time areas are required to
submit attainment demonstrations for the 8-hour ozone and
PM2.5 NAAQS, this strict interpretation could prevent any
changes to SIP control measures. EPA does not believe this strict
interpretation is necessary or appropriate.
Prior to the time that attainment demonstrations are due for the 8-
hour ozone and PM2.5 standards, it is unknown what suite of
control measures are needed for a given area to attain these standards.
During this period, to demonstrate no interference with any applicable
NAAQS or requirement of the Clean Air Act under section 110(l), EPA
believes it is appropriate to allow States to substitute equivalent
emissions reductions to compensate for the control measure being moved
from the active portion of the SIP to the contingency provisions, as
long as actual emissions in the air are not increased. EPA concluded
that preservation of the status quo air quality during the time new
attainment demonstrations are being prepared will prevent interference
with the States' obligations to develop timely attainment
demonstrations.
``Equivalent'' emissions reductions mean reductions which are equal
to or greater than those reductions achieved by the control measure to
be removed from the active portion of the SIP. To show the
compensating, emissions reductions are equivalent, modeling or adequate
justification must be provided. (EPA memorandum from John Calcagni,
Director, Air Quality Management Division, to the Air Directors in EPA
Regions 1-10, September 4, 1992, pages 10 and 13.) As stated in the May
11, 2004, letter referenced earlier, the compensating, equivalent
reductions must represent actual, new emissions reductions achieved in
a contemporaneous time frame to the termination of the existing SIP
control measure, in order to preserve the status quo level of emissions
in the air. In addition to being contemporaneous, the equivalent
emissions reductions must also be permanent, enforceable, quantifiable,
and surplus to be approved into the SIP.
[[Page 17034]]
B. What Is EPA's Analysis of Whether the Proposed Reductions Meet the
Criteria of Contemporaneous, Equivalent, Quantifiable, Permanent,
Enforceable, and Surplus?
The November 12, 2004, submittal proposes equivalent VOC emissions
reductions for the Northern Kentucky VET Program from two Kentucky
rules. The following is a description of how the proposed VOC emissions
reductions from two Kentucky rules, 401 KAR 59:185 and 401 KAR 59:760,
meet the six criteria of contemporaneous, equivalent (or greater),
permanent, enforceable, quantifiable, and surplus.
1. Contemporaneous
While ``contemporaneous'' is not explicitly defined in the Clean
Air Act, a reasonable interpretation is to enact the compensating,
equivalent emissions reductions within one year (prior to or following)
the cessation of the substituted control measure. The State effective
date of revisions to regulation 401 KAR 59:185 is January 4, 2005. The
State effective date of 401 KAR 59:760 is likely to occur, at the
latest, during the March-April 2005 timeframe, contingent on the
typical schedule of Kentucky's rulemaking process, with the emergency
version of this rule already in effect as of November 15, 2004. The
November 12, 2004, submittal requests two different effective dates for
the VET Program's closure. Kentucky will clarify in the final submittal
the correct date requested. The actual effective date is contingent
upon EPA's final action. In accordance with Kentucky Senate Joint
Resolution 3 dated March 29, 2004, the closure of the Northern Kentucky
VET Program is legislated to occur once EPA approves, through
rulemaking, a revision to the Kentucky SIP incorporating compensating,
equivalent emissions reductions to replace the VET Program. (To view a
copy of the Senate Joint Resolution 3, please see Appendix A of the
November 12, 2004, submittal available in EPA's RME system.) As long as
closure of the VET Program occurs within one year from the replacement
emissions reductions, these reductions will be contemporaneous to the
emissions reductions from both rules, 401 KAR 59:185 and 401 KAR
59:760.
2. Equivalent
The VET Program reduces emissions of VOC, NOX, and CO.
VOC and NOX are contributors (``precursors'') to the
formation of ground-level ozone and fine particulate matter. Thus, the
increase in VOC and NOX need to be offset with equivalent
(or greater) emissions reductions from another control measure(s) in
order to demonstrate non-interference with the 8-hour ozone and
PM2.5 NAAQS. Substitute CO emissions reductions are not
needed for this demonstration because the area is attaining the CO
NAAQS and CO levels in the area are well below the standard, as noted
in section III.C. of this document. It is unlikely that removing the
VET Program will interfere with the area's ability to continue to
attain the CO NAAQS.
a. Selection of the Year 2005 To Estimate Emission Increases From
Closure of the Northern Kentucky VET Program. To demonstrate that the
VOC emissions reductions from 401 KAR 59:185 and 401 KAR 59:760 provide
the equivalent benefit of the VOC and NOX emissions
reductions achieved by the VET Program, Kentucky first identified the
expected increases in emissions due to closure of the program for the
years 2005, 2008, and 2010. As shown in Table 3 below, VOC and
NOX emissions from onroad mobile sources are expected to
increase in 2005 by 0.78 tpsd and 0.29 tpsd, respectively, due to
closure of the Northern Kentucky VET Program. In 2008 and 2010,
expected VOC and NOX reductions from the VET Program
decline. In particular, NOX reductions are predicted to be
0.02 tpsd in 2008 and 0.09 tpsd for 2010. Thus, the year 2005 provides
the greatest number of VET Program emissions that need to be replaced.
For these reasons, EPA believes that analyzing emissions for 2005 is
conservative, and represents the greatest impact on air quality from
the Program's closure beginning in 2005, when emissions from the loss
of the Program would first impact the area.
Kentucky used MOBILE6.2, EPA's latest version of the mobile model
for estimating onroad mobile source emissions, to develop the onroad
mobile emission estimates for the Northern Kentucky area. The
MOBILE6.2-based emissions are proposed to replace the Mobile5a-
generated emissions in the current, approved 1-hour ozone maintenance
plan for the Northern Kentucky area.

b. Methodology for Substituting VOC for NOX to Determine
All ``VOC-Equivalent'' Needed To Replace the VET Program. To determine
the equivalent number of VOCs to replace 0.78 tpsd VOC and 0.29 tpsd
NOX emissions reductions predicted in 2005 from the VET
Program, Kentucky converted the 0.29 tpsd of NOX into VOC
using an equation developed in accordance with the August 5, 1994, EPA
memorandum, ``Clarification of Policy for Nitrogen Oxides
(NOX) Substitution,'' from John Seitz. This memorandum
pertains to EPA's ``NOX Substitution Guidance'' (December
1993). The guidance acknowledges that controlling only VOCs may not be
the most effective approach in all areas for attaining the ozone
standard, and allows for substitution of NOX for VOC
emissions reductions required for Reasonable Further Progress,
contingent upon approval by EPA. The 1994 memorandum further clarifies
that NOX for VOC substitution is a viable approach prior to
completing modeling to support an area's attainment demonstration.
Using the principles of EPA's NOX Substitution Guidance, EPA
will similarly allow substitution of VOC for NOX emissions
reductions on a percentage basis, where it is demonstrated that VOC
emissions reductions are effective in attaining or maintaining the
ozone NAAQS. Furthermore, the most recent authoritative assessments of
ozone control approaches 1 2 have concluded that although a
NOX control strategy
[[Page 17035]]
would be most effective for reducing regional scale ozone transport,
VOC reductions are most effective in more dense urbanized areas. The
Kentucky Counties of Boone, Campbell, and Kenton are in the Cincinnati-
Hamilton MSA adjacent to the highly populated Ohio Counties of Hamilton
and Clermont.

\2\ NARSTO, An Assessment of Tropospheric Ozone Pollution--A
North American Perspective, July 2000.
---------------------------------------------------------------------------
To determine the amount of VOC that will provide equivalent ozone
reduction benefits as the 0.29 tpsd of NOX, Kentucky used
the following equation in accordance with EPA guidance: (NOX
increase due to closure of the VET Program)/(Total NOX
Emissions for the Northern Kentucky Area) x (Total VOC Emissions for
the Northern Kentucky Area) = Equivalent VOC emissions reductions
required. This equation incorporates calculation of the VOC/
NOX ratio, which determines what a one percent reduction in
VOC is equivalent to, in tpsd, for a one percent reduction in
NOX. This ratio is based upon EPA's NOX
Substitution Guidance (December 1993). To calculate the VOC/
NOX ratio, the area's total VOC emissions are divided by the
area's total NOX emissions from all source categories for a
given year. For example, the 2005 VOC/NOX ratio is: (32.56
tpsd VOC)/(64.77 tpsd NOX) = (1 percent VOC reduction)/(1
percent NOX reduction) = 0.50 tpsd VOC/1.0 tpsd
NOX. Thus, to reduce 1.0 tpsd of NOX, 0.50 tpsd
of VOC is required to be reduced. Using this same calculation, the
ratios for 2008 and 2010 are 0.52 tpsd VOC/1.0 tpsd NOX and
0.53 tpsd VOC/1.0 tpsd NOX, respectively. In the 2005
example, the VOC/NOX ratio is then applied as follows to
solve for ``X'': 0.50 tpsd VOC/1.0 tpsd NOX = X tpsd VOC/
0.29 tpsd NOX. For 2005, ``X'' equals 0.145 or, with
rounding, 0.15 tpsd of VOC must be reduced to be equivalent to a 0.29
tpsd reduction of NOX. Similar calculations for 2008 and
2010 show that the equivalent amount of VOC emissions reductions needed
to replace the 0.29 tpsd NOX are 0.151 tpsd and 0.154 tpsd,
respectively, which both round to 0.15 tpsd VOC. This analysis shows
that the year used to develop the VOC/NOX ratio does not
alter, after rounding, the resulting amount of 0.15 tpsd VOC-equivalent
for 0.29 tpsd of NOX.
In the November 2004 submittal, Kentucky's methodology applied
total VOC and NOX emission data for the year 2010 in the
``VOC Equivalent Emissions'' equation above because this provides the
greatest number of VOC-equivalent emissions to replace. Kentucky
computed the VOC-equivalent to the 0.29 tpsd of NOX
emissions reductions expected in 2005 from the VET Program as follows:
(0.29 tpsd NOX)/(63.77 tpsd NOX) x (34.05 tpsd
VOC) = 0.1548 or, with rounding, 0.15 tpsd VOC. In the final submittal,
Kentucky will clarify references to the VOC/NOX ratio in the
November 2004 proposed revision to show how the ratios derived in
Appendices B and E are used in the ``VOC Equivalent Emissions''
equation above.
c. Equivalent Emissions Reductions From Two Kentucky Rules. To
calculate the total number of VOC emissions reductions needed to
replace the VET Program, Kentucky added the 0.15 tpsd VOC-equivalent of
0.29 tpsd NOX to the 0.78 tpsd VOC emissions increase
expected in 2005 from closure of the program, yielding 0.93 tpsd VOC
(i.e., 0.15 + 0.78). Thus, 0.93 tpsd of VOC emissions reductions are
needed to replace the VET Program.
As explained in the following section, ``4. Quantifiable,''
revisions to rule 401 KAR 59:185 and new rule 401 KAR 59:760 are
expected to reduce VOCs in 2005 by 0.71 tpsd and 0.27 tpsd,
respectively, yielding a total of 0.98 tpsd VOC emissions reductions
(i.e., 0.71 + 0.27 = 0.98) from these rules. These emissions reductions
exceed the 0.93 tpsd VOCs needed to replace the VET Program by 0.05
tpsd (i.e., 0.98-0.93 = 0.05).
Therefore, based on this conservative equivalency analysis, the
proposed 0.98 tpsd of VOC reductions from the two Kentucky rules are
equivalent, in terms of reduced ozone formation benefits, to the VOC
and NOX reductions from the VET Program. In addition, VOC
and NOX, the relevant pollutants controlled by the VET
Program, are contributing precursors to the formation of
PM2.5 and thus, EPA concludes that these equivalent
reductions also demonstrate non-interference with the PM2.5
NAAQS.
3. Quantifiable
The November 12, 2004, submittal shows that in 2005, 0.71 tpsd of
VOC will be reduced through the revisions to rule 401 KAR 59:185, and
0.27 tpsd of VOCs will be reduced through rule 401 KAR 59:760. The
emissions reductions meet the criterion for quantifiable, as the VOC
emissions reductions may be calculated as follows.
The rule revisions to 401 KAR 59:185 establish a vapor pressure
limit for solvents used in cold cleaning degreasing operations in the
Northern Kentucky Counties of Boone, Campbell, and Kenton. Section
4(3)(a) of the regulation requires that vendors provide in these
counties only solvents with a vapor pressure at or below 1.0
millimeters (mm) of mercury measured at 20 degrees Celsius for solvents
sold in units greater than five gallons for use in cold cleaners.
Section 4(3)(b) prohibits operations of a cold cleaner using a solvent
exceeding the vapor pressure limit described for section 4(3)(a). In
addition, section 4(4) of the regulation requires users to keep records
of their solvent purchases.
To determine the amount of VOC reductions from revisions to 401 KAR
59:185 affecting the Northern Kentucky counties, the projected 2005
cold cleaning degreasing emissions (in tpsd) for these counties are
multiplied by 67 percent, which is the control efficiency (CE) of the
rule, and 80 percent, which is the rule effectiveness (RE) factor. The
CE provides an estimate of the percent VOC reduction expected from
lowering the vapor pressure limit in the rule as described above. The
67 percent CE has been used in similar cold cleaning degreasing
regulations in the States of Indiana, Illinois, and Maryland. The RE
factor of 80 percent is an EPA estimate of the effectiveness of this
type of rule. The results of this calculation provide the 2005 cold
cleaning degreasing estimated emissions reductions. For example, in
Boone County, 0.32 tpsd of VOC emissions are projected for 2005 from
cold cleaning degreasing. This 2005 cold cleaning degreasing projection
was derived from identifying the percent contribution to the 2005 VOC
projections from the total solvent degreasing area source category
listed in Appendix I of the Northern Kentucky 1-Hour Ozone Maintenance
Plan approved by EPA into the Kentucky SIP. Using EPA emission factors,
Kentucky determined that cold cleaning degreasing VOC emissions
contribute 84 percent to the total solvent degreasing emission
projection of 0.38 tpsd VOC, i.e., (0.38 tpsd VOC) x (84 percent) =
0.32 tpsd VOC. Using the multipliers described above for the Boone
County example, (0.32 tpsd VOC) x (67 percent CE) x (80 percent RE) =
0.17 tpsd VOC cold cleaning degreasing emissions are expected to be
reduced in 2005 from the rule revisions. Table 4 below presents the VOC
reductions expected for Boone, Campbell, and Kenton Counties from the
revisions to 401 KAR 59:185, which total 0.71 tpsd VOC.

To determine the amount of VOC reductions in the Northern Kentucky
counties from new rule, 401 KAR 59:760, calculations similar to what
are described for 401 KAR 59:185 are made. Kentucky applied a 35
percent CE for implementation of high transfer efficiency spray gun
technology required by this rule. This 35 percent CE is based on
figures provided in the Ozone Transport Commission Pechan Report, dated
March 31, 2001, and CEs approved by EPA in other areas. Kentucky also
applied EPA's default 80 percent RE factor, resulting in 0.27 tpsd VOC
are predicted to be reduced in 2005 from 401 KAR 59:760. Table 5 below
presents the VOC reductions expected for Boone, Campbell, and Kenton
Counties from 401 KAR 59:760, which total 0.27 tpsd VOC.

EPA has reviewed the calculations, methodology, and supporting
analyses provided by Kentucky and agrees with the 2005 VOC emission
reduction estimates of 0.71 tpsd and 0.27 tpsd for 401 KAR 59:185 and
401 KAR 59:760, respectively, described above and summarized in Tables
4 and 5.
4. Permanent
The emissions reductions from Kentucky rules, 401 KAR 59:185 and
401 KAR 59:760, are made permanent through Kentucky's rulemaking
process. Once State effective, these regulations have the full force of
a law and establish obligatory requirements applicable to affected
groups. EPA's approval of the final SIP revision will incorporate
revisions to 401 KAR 59:185 and new rule 59:760 into the federally
enforceable Kentucky SIP. EPA is not taking action on emergency rule,
401 KAR 59:760E, included in the November 12, 2004, submittal because
the rule has an expiration date under Kentucky Revised Statute 13A.190,
and thus, is not permanent. Since the emissions reductions from the
emergency rule are not included in the calculation of equivalent
emissions reductions needed to replace the VET Program, EPA inaction on
this rule does not affect the approvability of this proposed revision.
5. Enforceable
The emissions reductions are enforceable by the Commonwealth of
Kentucky as of the State effective date of these regulations. Upon
final approval into the Kentucky SIP, revised rule 401 KAR 59:185 and
new rule 59:760 will be Federally enforceable by the EPA, as of the
effective date of EPA's final rulemaking.
6. Surplus
The VOC emissions reductions from Kentucky's two rules are surplus
for two reasons. The emissions reductions go beyond the reductions
already required in the Kentucky SIP, and the reductions are not from a
Federal Control Measure that would occur without any State or local
action. Specifically, the 0.71 tpsd of VOC emissions reductions from
revisions to 401 KAR 59:185 are due to new provisions created in
sections 4(3) and 4(4) which prohibit the sale and use of solvents with
vapor pressure limits exceeding that specified in the regulation. Rule
401 KAR 59:760 is a new regulation proposed for inclusion into the
Kentucky SIP, which will provide 0.27 tpsd of VOC emissions reductions
in 2005 from requirements to use high transfer efficiency spray gun
technology at mobile equipment refinishing operations in Northern
Kentucky.
V. What Is EPA's Proposed Action?
EPA is proposing to move 401 KAR 65:010, ``Vehicle emission control
programs'' from the active control measure portion of the Kentucky SIP
to the contingency measures section of the Northern Kentucky 1-Hour
Ozone Maintenance Plan. EPA is also proposing to approve revisions to
Kentucky rule 401 KAR 59:185, ``New solvent metal cleaning equipment''
and the addition of new rule 401 KAR 59:760, ``Commercial Motor Vehicle
and Mobile Equipment Refinishing Operations,'' into the Kentucky SIP.
Finally, EPA is proposing to approve updated mobile source category
emission projections using MOBILE6.2, with updated, subarea MVEBs of
7.68 tpsd VOC and 17.42 tpsd NOX for the year 2010. EPA's
proposed approval is contingent upon Kentucky addressing
[[Page 17037]]
the requested clarifications in EPA's December 29, 2004, comment letter
on this proposed SIP revision. Kentucky must include a demonstration of
non-interference with the CO NAAQS, as demonstrated by very low levels
of ambient CO--well below the NAAQS--and the fact that the area is in
attainment of the CO NAAQS. Kentucky must also clarify references to
the VOC/NOX ratio and modify subsection (1)(j) of section 3,
``Operating requirements,'' of 401 KAR 59:760. This subsection uses
language which mirrors that of the Ozone Transport Commission model
rule. However, to be consistent with current Agency policy, this
language needs to be revised to include some form of public review for
determining other coating application methods which achieve emissions
reductions equivalent to high volume low pressure or electrostatic
spray application methods. In the current language proposed, the
Kentucky Cabinet makes this determination.
VI. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
proposed action is not a ``significant regulatory action'' and
therefore is not subject to review by the Office of Management and
Budget. For this reason, this action is also not subject to Executive
Order 13211, ``Actions Concerning Regulations That Significantly Affect
Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This
proposed action merely proposes to approve State law as meeting Federal
requirements and imposes no additional requirements beyond those
imposed by State law. Accordingly, the Administrator certifies that
this proposed rule will not have a significant economic impact on a
substantial number of small entities under the Regulatory Flexibility
Act (5 U.S.C. 601 et seq.). Because this rule proposes to approve pre-
existing requirements under State law and does not impose any
additional enforceable duty beyond that required by State law, it does
not contain any unfunded mandate or significantly or uniquely affect
small governments, as described in the Unfunded Mandates Reform Act of
1995 (Public Law 104-4).
This proposed rule also does not have tribal implications because
it will not have a substantial direct effect on one or more Indian
tribes, on the relationship between the Federal Government and Indian
tribes, or on the distribution of power and responsibilities between
the Federal Government and Indian tribes, as specified by Executive
Order 13175 (65 FR 67249, November 9, 2000). This action also does not
have Federalism implications because it does not have substantial
direct effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government, as specified
in Executive Order 13132 (64 FR 43255, August 10, 1999). This action
merely proposes to approve a State rule implementing a Federal
standard, and does not alter the relationship or the distribution of
power and responsibilities established in the Clean Air Act. This
proposed rule also is not subject to Executive Order 13045 ``Protection
of Children from Environmental Health Risks and Safety Risks'' (62 FR
19885, April 23, 1997), because it is not economically significant.
In reviewing SIP submissions, EPA's role is to approve State
choices, provided that they meet the criteria of the Clean Air Act. In
this context, in the absence of a prior existing requirement for the
State to use voluntary consensus standards (VCS), EPA has no authority
to disapprove a SIP submission for failure to use VCS. It would thus be
inconsistent with applicable law for EPA, when it reviews a SIP
submission, to use VCS in place of a SIP submission that otherwise
satisfies the provisions of the Clean Air Act. Thus, the requirements
of section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) do not apply. This proposed rule does
not impose an information collection burden under the provisions of the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
