ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[OH148-1a; FRL-7001-6]


Approval and Promulgation of Maintenance Plan Revisions; Ohio

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is approving a May 31, 2001, request from Ohio for a State 
Implementation Plan (SIP) revision of the Cleveland/Akron/Lorain ozone 
maintenance plan. The maintenance plan revision establishes a new 
transportation conformity mobile source emissions budget for the year 
2006. EPA is approving the allocation of a portion of the safety margin 
for volatile organic compounds (VOCs) to the area's 2006 mobile source 
emissions budget for transportation conformity purposes. This 
allocation will still maintain the total emissions for the area at or 
below the attainment level required by the transportation conformity 
regulations. The transportation conformity budget for oxides of 
nitrogen will remain the same as previously approved in the maintenance 
plan.

DATES: This rule is effective on August 6, 2001, unless EPA receives 
adverse written comments by July 23, 2001. If adverse comment is 
received, EPA will publish a timely withdrawal of the rule in the 
Federal Register and inform the public that the rule will not take 
effect.

ADDRESSES: Send written comments to: J. Elmer Bortzer, Chief, 
Regulation Development Section, Air Programs Branch, (AR-18J), U.S.

I. What Action Is EPA Taking Today?

    In this action, we are approving a revision to the ozone 
maintenance plan for Cleveland/Akron/Lorain, Ohio. The revision will 
change the mobile source emissions budget for VOC that is used for 
transportation conformity purposes. The revision will keep the total 
emissions for the area at or below the attainment level required by 
law. This action will allow State or local agencies to maintain air 
quality while providing for transportation growth.

II. Who Is Affected by This Action?

    Primarily, the transportation sector (represented by Ohio 
Department of Transportation), the metropolitan planning organizations 
for Cleveland and Akron and persons needing to travel in the Cleveland/
Akron/Lorain area will be affected by this revision. The proposed 
transportation plans and programs for the Cleveland/Akron/Lorain area 
must demonstrate conformity to the emissions budget in the State 
Implementation Plan (SIP). Analysis of the current proposed 
transportation plan indicates that it would produce higher emissions 
than currently allowed in the maintenance plan. The conformity rule, 
however, provides that if a ``safety margin'' exists in the maintenance 
plan, then the safety margin can be allocated to the transportation 
sector via the mobile source budget.

III. How Did the State Support Its Request?

    On May 31, 2001, Ohio submitted to EPA a SIP revision request for 
the Cleveland/Akron/Lorain ozone maintenance area. A public hearing on 
this proposal was held on June 13, 2001. No one from the public 
commented on the proposed revisions.
    In the submittal, Ohio requested to establish a new 2006 mobile 
source emissions budget for VOC for the Cleveland/Akron/Lorain, Ohio, 
ozone maintenance area. The State requested that 10 tons of VOC be 
allocated from the maintenance plan's safety margin of 86.3 tons of 
VOC. The mobile source budgets are used for transportation conformity 
purposes.

IV. What Is Transportation Conformity?

    Transportation conformity means that the level of emissions from 
the transportation sector (cars, trucks and buses) must be consistent 
with the requirements in the SIP to attain and maintain the air quality 
standards. The Clean Air Act, in section 176(c), requires conformity of 
transportation plans, programs and projects to an implementation plan's 
purpose of attaining and maintaining the National Ambient Air Quality 
Standards. On November 24, 1993, EPA published a final rule 
establishing criteria and procedures for determining if transportation 
plans, programs and projects funded or approved under Title 23 U.S.C. 
or the Federal Transit Act conform to the SIP.
    The transportation conformity rules require an ozone maintenance 
area, such as Cleveland/Akron/Lorain, to compare the actual projected 
emissions from cars, trucks and buses on the highway network, to the 
mobile source emissions budget established by a maintenance plan. The 
Cleveland/Akron/Lorain area has an approved ozone maintenance plan. Our 
approval of the maintenance plan established the mobile source 
emissions budgets for transportation conformity purposes.

V. What Is an Emissions Budget?

    An emissions budget is the projected level of controlled emissions 
from the transportation sector (mobile sources) that is estimated in 
the SIP. For example, the SIP controls emissions through regulations on 
fuels and exhaust levels for cars. The emissions budget 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 mobile source emissions budget in the 
SIP and how to revise the emissions budget. The transportation 
conformity rule allows the mobile source emissions budget to be changed 
as long as the total level of emissions from all sources remains below 
the attainment level.

VI. What Is a Safety Margin?

    A ``safety margin'' is the difference between the attainment level 
of emissions (from all sources) and the projected level of emissions 
(from all sources) in the maintenance plan. The attainment level of 
emissions is the level of emissions during one of the years in which 
the area met the air quality health standard. For example: Cleveland/
Akron/Lorain was monitoring attainment of the one hour ozone standard 
during 1993, and the 1993 level was used for the attainment year 
inventory in the approved maintenance plan. The emissions from point, 
area and mobile sources in 1993 equaled 458.5 tons per day of VOC and 
495.1 tons per day of oxides of nitrogen ( NO<INF>X</INF>). The Ohio 
Environmental Protection Agency projected emissions out to the year 
2006 and projected a total of 338.3 tons per day of VOC and 453.6 tons 
per day of NO<INF>X</INF> from all sources in Cleveland/Akron/Lorain. 
The safety margin for Cleveland/Akron/Lorain is calculated to be the 
difference between these amounts or 120.2 tons per day of VOC and 41.5 
tons per day of NO<INF>X</INF>.
    In 1997, part of the safety margin for both VOC and NO<INF>X</INF> 
was allocated to mobile sources (see 62 FR 44903 published on August 
25, 1997). The remaining safety margin for the area after the 
allocation in 1997 is 86.3 tons per day VOC and 12.5 tons per day 
NO<INF>X</INF>. Table 1 gives detailed information on the estimated 
emissions from each source category and the safety margin calculation 
after the 1997 allocation of the safety margin to the mobile source 
budgets.
    The 2006 emission projections reflect the point, area and mobile 
source reductions and are illustrated in Table 1.

    The emissions are projected to maintain the area's air quality 
consistent with the air quality health standard. The safety margin 
credit can be allocated to the transportation sector. The total 
emission level, even with this allocation will be below the attainment 
level, or safety level, and thus is acceptable. The safety margin is 
the extra safety [points] that can be allocated as long as the total 
level is maintained.

VII. How Does This Action Change the Cleveland/Akron/Lorain Ozone 
Maintenance Plan?

    It raises the VOC emissions budget for mobile sources. The 
maintenance plan is designed to provide for future growth while still 
maintaining the ozone air quality standard. Growth in industries, 
population, and traffic is offset with reductions from cleaner cars and 
other emission reduction programs. Through the maintenance plan the 
State and local agencies can manage and maintain air quality while 
providing for growth.
    In the submittal, Ohio requested to allocate part of the area's 
safety margin to the mobile source emissions budget. The Cleveland/
Akron/Lorain/Lorain area's safety margin is the difference between the 
1993 attainment inventory year and the 2006 projected emissions 
inventory (86.3 tons/day VOC safety margin, and 12.5 tons/day 
NO<INF>X</INF> safety margin) as shown in Table 1. The SIP revision 
requests the allocation of 10 tons/day VOC into the area's mobile 
source VOC emissions budget from the safety margin. The 2006 mobile 
source VOC emissions budget showing the safety margin allocations are 
outlined in Table 2. The mobile source VOC emissions budget in Table 2 
will be used for transportation conformity purposes.
    Table 2 below illustrates that the requested portion of the safety 
margin can be allocated to the 2006 VOC mobile source budget and that 
total emissions will still remain at or below the 1993 attainment level 
of total emissions for the Cleveland/Akron/Lorain maintenance area. 
Since the area would still be at or below the 1993 attainment level for 
the total emissions, this allocation is allowed by the conformity rule. 
The NO<INF>X</INF> budget and safety margin will remain the same.

VIII. Why Is the Request Approvable?

    After review of the SIP revision request, EPA finds that the 
requested allocation of the safety margin for the Cleveland/Akron/
Lorain area is approvable because the new mobile source emissions 
budget for VOC maintains the total emissions for the area at or below 
the attainment year inventory level as required by the transportation 
conformity regulations. This allocation is allowed by the conformity 
rule since the area would still be at or below the 1993 attainment 
level for the total emissions.

IX. EPA Action

    EPA is approving the requested allocation of the safety margin to 
the mobile source VOC emission budget for the Cleveland/Akron/Lorain 
ozone maintenance area.
    EPA is publishing this action without prior proposal because EPA 
views this as a noncontroversial revision and anticipates no adverse 
comments. However, in a separate document in this Federal Register 
publication, EPA is proposing to approve the SIP revision should 
adverse written comments be filed. This action will be effective 
without further notice unless EPA receives relevant adverse written 
comment by July 23, 2001. Should the Agency receive such comments, it 
will publish a final rule informing the public that this action will 
not take effect. Any parties interested in commenting on this action 
should do so at this time. If no such comments are received, the public 
is advised that this action will be effective on August 6, 2001.

X. Administrative Requirements

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and therefore is not 
subject to review by the Office of Management and Budget. This action 
merely approves state law as meeting federal requirements and imposes 
no additional requirements beyond those imposed by state law. 
Accordingly, the Administrator certifies that this 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 approves 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 rule also does 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), nor will it 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), because it 
merely approves 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 rule also is 
not subject to Executive Order 13045 (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

[[Page 33478]]

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. 
As required by section 3 of Executive Order 12988 (61 FR 4729, February 
7, 1996), in issuing this rule, EPA has taken the necessary steps to 
eliminate drafting errors and ambiguity, minimize potential litigation, 
and provide a clear legal standard for affected conduct. EPA has 
complied with Executive Order 12630 (53 FR 8859, March 15, 1988) by 
examining the takings implications of the rule in accordance with the 
``Attorney General's Supplemental Guidelines for the Evaluation of Risk 
and Avoidance of Unanticipated Takings'' issued under the executive 
order. This 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.).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2). This rule will be effective August 6, 2001 unless EPA receives 
adverse written comments by July 23, 2001.
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by August 21, 2001. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this rule for the purposes of judicial 
review nor does it extend the time within which a petition for judicial 
review may be filed, and shall not postpone the effectiveness of such 
rule or action. This action may not be challenged later in proceedings 
to enforce its requirements. (See section 307(b)(2).)

area's NO<INF>X</INF> safety margin to the transportation conformity 
mobile source emissions budget. The mobile source emissions budgets for 
transportation conformity purposes for the Cleveland/Akron/Lorain area 
are now: 92.7 tons per day of volatile organic compound emissions for 
the year 2006 and 104.4 tons per day of oxides of nitrogen emissions 
for the year 2006. This approval only changes the VOC transportation 
conformity emission budget for Cleveland/Akron/Lorain.
