Technical Amendment to the Finding of Significant Contribution 
and Rulemaking for Certain States for Purposes of Reducing Regional 
Transport of Ozone

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; technical amendment.

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

SUMMARY: The EPA is revising the oxides of nitrogen (NOX) 
statewide emissions budgets for the 22 States and the District of 
Columbia that are required to submit State implementation plan (SIP) 
revisions to address the regional transport of ozone (also referred to 
as the NOX SIP call). These revisions are based on the 
comments received during the comment period for emissions inventory 
revisions to 2007 baseline sub-inventory information used to establish 
each State's budget in the NOX SIP call.

DATES: This rule is effective June 14, 1999.

ADDRESSES: Dockets containing information relating to this rulemaking 
(Docket Nos. A-96-56, A-97-43, and A-98-12) are available for public 
inspection at the Office of Air and Radiation Docket and Information

SUPPLEMENTARY INFORMATION: By notice dated October 27, 1998, EPA 
published, ``Finding of Significant Contribution and Rulemaking for 
Certain States in the Ozone Transport Assessment Group Region for 
Purposes of Reducing Regional Transport of Ozone'' (63 FR 57356), which 
may be referred to as the NOX SIP call. The final 
NOX SIP call provided that the opportunity for comments on 
2007 baseline sub-inventory revisions would be available for 60 days 
after signature of the NOX SIP call.
    The EPA received numerous requests to allow more time to accept 
revisions to source-specific inventory data used to establish each 
State's emissions baseline and budget in the NOX SIP call 
and to also allow revisions to vehicle miles traveled (VMT) 
projections. Therefore, by notice dated December 24, 1998, EPA 
published, ``Correction and Clarification to the Finding of Significant 
Contribution and Rulemaking for Purposes of Reducing Regional Transport 
of Ozone'' (63 FR 71220), which may be referred to as the correction 
notice.
    In these notices, EPA reopened and extended the comment period on 
emissions inventory revisions to 2007 baseline sub-inventory 
information used to establish each State's budget in the NOX 
SIP call. This included source-specific emission inventory data, data 
on VMT and nonroad mobile growth rates, VMT distribution by vehicle 
class, average speed by roadway type, inspection and maintenance 
program parameters, and other input parameters used in the calculation 
of highway vehicle emissions. The EPA extended this time period for 
additional comment to February 22, 1999 in the correction notice.
    The EPA is proceeding to final action now based on the comments 
received from the public in response to this extended comment period. 
To the extent the Administrative Procedure Act might require 
publication of a notice of proposed rulemaking for this action, EPA 
finds good cause to dispense with such proposal, because EPA has 
already provided an opportunity for public comment (5 U.S.C. 
553(b)(B)).

I. Public Comments

    The EPA stated in ``Correction and Clarification to the Finding of 
Significant Contribution and Rulemaking for Purposes of Reducing 
Regional Transport of Ozone'' that the Agency would evaluate the data 
submitted by commenters and, if it was determined to be technically 
justified, revise the State baseline inventory and budgets for the 
NOX SIP call to reflect the new data by April 23, 1999. The 
Agency received approximately 300 comments. The Response to Comment 
Document (RTC) entitled ``Responses to the 2007 Baseline Sub-inventory 
Information and Significant Comments for the Final NOX SIP 
Call,'' addresses EPA's response to the submitted comments in detail. 
The EPA also

[[Page 26299]]

developed a technical support document (TSD) entitled ``Development of 
Emission Budget Inventories for the Regional Transport NOX 
SIP call.'' Upon promulgation of this technical amendment (i.e., 
signature), the TSD and RTC documents will be available in the dockets 
and the website listed above in ADDRESSES. All comments were considered 
in finalizing this technical amendment including numerous comments 
submitted after the February 22, 1999 deadline and those where the 
commenter did not adhere to the requests for data that were specified 
in the final NOX SIP call and the correction notice. 
Individuals interested in the specific modifications requested by 
commenters may review the materials as they were submitted to the 
dockets.

II. Major Changes to the Statewide NOX Emissions Budgets

    Changes to the Statewide NOX emissions budgets are 
mainly in response to the comments submitted during the reopened and 
extended comment periods indicated in the section above. Each of the 
sub-inventory sectors of EGU, non-EGU point, area, nonroad mobile, and 
highway mobile were commented on and affected by these comments and EPA 
action.
    As a result of these revisions, EPA anticipates that full 
implementation of the NOX SIP call will reduce total 
NOX emissions by 1.142 million tons. This is a slight 
decrease from the 1.157 million tons in total NOX reductions 
from the final NOX SIP call. The total overall percent 
reduction decreased slightly from 28 percent to 25 percent as a result 
of an increase in the emissions inventory baseline. Even though there 
was a slight increase in the overall NOX emissions 
inventory, EPA expects that the air quality benefits and the impacts on 
cost-effectiveness would remain virtually the same because the 
emissions change is so small.
    The EGU source budgets increased by less than 1 percent. A number 
of EGU point source units were reclassified to the non-EGU source 
sector and some non-EGU sources were reclassified to the EGU source 
sector. Further, in response to comments, the EGU budget also adds 
previously unidentified EGUs. Overall, the emissions reductions from 
this sector are similar to the emissions reductions of the final 
NOX SIP call.
    The non-EGU source budgets increased by 14 percent for several 
reasons. First, many sources were reclassified from large non-EGUs to 
small non-EGUs, thereby removing them from the category of sources 
requiring budget level controls. Second, some non-EGU units for which 
EPA assumed controls were reclassified to categories for which controls 
were not assumed; this reclassification results in excluding them from 
budget level controls (e.g., large industrial boiler reclassified as a 
glass manufacturer). Many State and local agencies submitted revised 
non-EGU point source inventories which replaced their final 
NOX SIP call inventory for non-EGUs. A number of non-EGU 
point source units were reclassified to the EGU source sector and a 
number of EGU sources were reclassified to the non-EGU source sector. 
The result of all of these reclassifications is that fewer non-EGUs 
would be subject to EPA's assumed control strategy. Consequently, the 
overall result of these changes increased the non-EGU budget by 14 
percent. Because the 2007 base budget increased, but the total number 
of units that would be subject to controls under EPA's assumed control 
strategy decreased, these changes lower the amount of emissions 
expected to be reduced by the NOX SIP call by 12,070 tons.
    Changes in the stationary area source budgets resulted in an 
overall budget increase of 11 percent. Some State and local agencies 
submitted revised stationary area source inventories to replace their 
final NOX SIP call inventory. In addition, EPA is applying a 
more consistent method for calculating ozone season emissions based on 
typical ozone season daily emissions. To retain consistency in State 
ozone season estimation methods, EPA is estimating seasonal emissions 
budgets by multiplying the typical ozone season day emission value by 
the number of days in the ozone season. Since EPA does not apply any 
controls to this source sector in calculating the reductions for the 
final NOX SIP call, there is no expected effect on the 
overall reduction due to these changes.
    Changes in the nonroad mobile source budget resulted in an overall 
increase of 19 percent. The EPA applied the same ozone season 
estimation methods change described above for stationary area sources 
to the nonroad mobile source budget. Several State and local agencies 
provided emissions growth and control data for use in estimating the 
nonroad sector of the budgets. Since EPA does not apply any controls to 
this source sector in calculating the reductions for the final 
NOX SIP call, there is no expected affect on the overall 
reduction due to these changes.
    Changes in the highway mobile source sector resulted in a 14 
percent budget increase. Differences in the highway sector of the State 
emissions budgets are in response to State and local agency comments on 
VMT, VMT growth, vehicle mix throughout the State, State to county 
level VMT allocations, speed changes by vehicle and roadway type, and 
inspection and maintenance program application, as well as EPA's 
inclusion of excess NOX emissions from the use of ``defeat 
devices'' on highway heavy-duty diesel engines. This latter effect is 
discussed more fully in the following section. Since EPA does not apply 
any controls to this source sector in calculating the reductions for 
the final NOX SIP call, there is no expected effect on the 
overall reduction due to these changes.

III. Heavy-Duty Diesel Emission Estimates

    The final NOX budget numbers EPA is presenting today 
include the effects of excess NOX emissions from highway 
heavy-duty diesel engines with ``defeat devices.'' These diesel engines 
use computer software that cause the effectiveness of the engines' 
emission control systems to be reduced. In essence, the computer 
software alters the fuel injection timing when the engine operates in 
certain modes (such as highway driving), causing the engine to emit 
higher levels of NOX than indicated by their certification 
standards or by EPA's existing emission models.
    In September of 1998, when EPA developed the budgets for the final 
NOX SIP call, EPA had not yet completed its evaluation of 
the impact of these defeat devices on NOX emissions. As a 
result, EPA did not include the added emissions in those NOX 
budgets. Since that time, EPA has completed its evaluation and entered 
into proposed consent decrees with the manufacturers of diesel engines 
equipped with these devices. These consent decrees would commit the 
manufacturers to reduce emissions from their engines and cease 
equipping them with defeat devices according to an agreed-upon 
schedule, and to take steps to mitigate the emissions effects of 
existing engines equipped with defeat devices. These mitigation 
commitments include the early introduction of heavy-duty diesel engines 
that will meet the more stringent NOX standards scheduled to 
take effect in 2004. Additional information regarding the defeat device 
consent decrees can be found in ``Notices of Filing of Consent Decree 
under the Clean Air Act'' (63 FR 59330-59334, November 3, 1998). 
Additional information about defeat devices and their emissions effects 
can be obtained from the U.S. EPA's Office of Mobile Sources by 
contacting the Engine Compliance Programs Group at (202) 564-9240 and 
requesting document

[[Page 26300]]

VPCD-98-13 (HD Engine), dated October 15, 1998.
    The EPA believes that the emissions impact of defeat devices peaked 
in the late 1990s and subsequently will decline rapidly as newer 
engines replace defeat device-equipped engines and as manufacturers 
undertake the mitigation commitments required under the proposed 
consent decrees. The final baseline NOX emission projections 
and NOX budgets presented in this notice include the effects 
of defeat devices and the commitments made by diesel engine 
manufacturers in the settlement to introduce diesel engines meeting the 
2004 standards prior to 2004. Including the emissions due to defeat 
devices in the statewide NOX emissions budgets will not, by 
themselves, alter the emission reductions that will result from the 
final NOX SIP call, because the change in baseline and 
budget amounts is identical. The increase in NOX budgets 
varies from State to State but averages approximately 5.6 percent 
across the entire 37-State OTAG domain, which EPA believes approximates 
the increase in the States covered by the final NOX SIP 
call. The EPA does not believe this increase is sufficiently large to 
alter the conclusions regarding significant contribution or estimates 
of the overall benefits of the rule, although it may alter the 
projected benefits of the rule in specific locations.
    The EPA is including the effects of the defeat devices in this 
technical amendment even though they were not available at the time of 
proposal or for the final NOX SIP call. The EPA finds good 
cause to use this information without prior proposal. Comment would be 
unnecessary since EPA will be including the effects of the defeat 
devices in both the calculation of the baseline inventories and the 
establishment of the SIP call budgets. Because the effects of the 
defeat devices will be included in both the baseline and the emission 
levels that must be achieved, inclusion of the effects will not alter 
the obligations that the affected States must meet to comply with the 
SIP call. The result of this change does not alter the tons of 
NOX reductions that the States must achieve, nor does it 
change the type of controls States are expected to select to reduce 
NOX emissions. This change will more accurately reflect 
EPA's current understanding of emissions from highway mobile sources. 
Therefore, EPA finds good cause to include these effects in this final 
action.

\1\ The majority of D.C.'s capacity is projected to shut down by 2007. Thus the 2007 base tonnage is very low.
  The budget target for all States is based on current capacity.

V. Administrative Requirements

A. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 804 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. The 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 U.S. prior to 
publication of the rule in the Federal Register. This rule is not a 
``major rule'' as defined by 5 U.S.C. 804(2).

B. Executive Order 12866

    Under Executive Order (E.O.) 12866, (58 FR 51735, October 4, 1993), 
this technical amendment is not a ``significant regulatory action'' and 
is therefore not subject to review by the Office of Management and 
Budget (OMB) because this action simply revises the emissions budget 
numbers of the NOX SIP call final rule. The final 
NOX SIP call was submitted to OMB for review. The EPA 
prepared a regulatory impact analysis (RIA) for the final 
NOX SIP call titled ``Regulatory Impact Analysis for the 
NOX SIP Call, FIP, and Section 126 Petitions.'' The RIA and 
any written comments from OMB to EPA and any written EPA responses to 
those comments are included in the docket. The docket is available for 
public inspection at the EPA's Air Docket Section, which is listed in 
the ADDRESSES section of this preamble. This technical amendment does 
not create any additional impacts beyond what was promulgated in the 
final NOX SIP call, therefore, no additional RIA is needed.

C. Unfunded Mandates Reform Act

    This technical amendment also does not impose any enforceable duty, 
contain any unfunded mandate, or impose any significant or unique 
impact on small governments as described in the Unfunded Mandates 
Reform Act of 1995 (UMRA) (Pub. L. 104-4). The EPA did not reach a 
final conclusion as to the applicability of the requirements of the 
UMRA to the final NOX SIP call. The EPA prepared a statement 
that would be required by UMRA if its statutory provisions applied and 
has consulted with governmental entities as would be required by UMRA. 
Because today's technical amendment does not create any additional 
mandates, no further UMRA analysis is needed.

D. Executive Order 12875

    This technical amendment also does not require prior consultation 
with State, local, and tribal government officials as specified by 
Executive Order 12875 (58 FR 58093, October 28, 1993). The final 
NOX SIP call did not create a mandate on State, local or 
tribal governments. As explained in the final NOX SIP call 
in the discussion of UMRA and the Executive Order 12875, the final rule 
did not impose an enforceable duty on these entities. Therefore, the 
Executive Order 12875 does not apply to this technical amendment to the 
final NOX SIP call.

E. Executive Order 13084

    The EPA stated in the final NOX SIP call that Executive 
Order 13084 (63 FR 27655, May 10, 1998) did not apply because the final 
rule does not significantly or uniquely affect the communities of 
Indian tribal governments or call on States to regulate NOX 
sources located on tribal lands.

F. Executive Order 12898

    In addition, since today's action is a technical amendment, this 
action does not involve special consideration of environmental justice 
related issues as required by E.O. 12898 (59 FR 7629, February 16, 
1994). For the final NOX SIP call, the Agency conducted a 
general analysis of the potential changes in ozone and particulate 
matter levels that may be experienced by minority and low-income 
populations as a result

[[Page 26305]]

of the requirements of the rule. These findings are presented in the 
RIA.

G. Regulatory Flexibility Act

    This technical amendment is not subject to the regulatory 
flexibility provisions of the Regulatory Flexibility Act (5 U.S.C. 601 
et seq.). Both the final NOX SIP call and this technical 
amendment will not have a significant impact on a substantial number of 
small entities because this action does not establish requirements 
applicable to small entities.

H. Executive Order 13045

    This technical amendment also is not subject to E.O. 13045 
(Protection of Children from Environmental Health Risks and Safety 
Risks) (62 FR 19885, April 23, 1997) because EPA interprets E.O. 13045 
as applying only to those regulatory actions that are based on health 
or safety risks, such that the analysis required under section 5-501 of 
the Order has the potential to influence the regulation. This technical 
amendment is not subject to E.O. 13045 because it does not establish an 
environmental standard intended to mitigate health or safety risks and 
is not economically significant under E.O. 12866.

I. National Technology Transfer and Advancement Act

    In addition, the National Technology Transfer and Advancement Act 
of 1997 does not apply because today's technical amendment does not 
require the public to perform activities conducive to the use of 
voluntary consensus standards under that Act. The EPA's compliance with 
these statutes and Executive Orders for the underlying rule, the final 
NOX SIP call, is discussed in more detail in 63 FR 57477-81 
(October 27, 1998).

J. Judicial Review

    Section 307(b)(1) of the Clean Air Act (CAA) indicates which 
Federal Courts of Appeal have venue for petitions of review of final 
actions by EPA. This section provides, in part, that petitions for 
review must be filed in the Court of Appeals for the District of 
Columbia Circuit if (i) the agency action consists of ``nationally 
applicable regulations promulgated, or final action taken, by the 
Administrator,'' or (ii) such action is locally or regionally 
applicable, if ``such action is based on a determination of nationwide 
scope or effect and if in taking such action the Administrator finds 
and publishes that such action is based on such a determination.''
    Any final action related to the NOX SIP call is 
``nationally applicable'' within the meaning of section 307(b)(1). As 
an initial matter, through this rule, EPA interprets section 110 of the 
CAA in a way that could affect future actions regulating the transport 
of pollutants. In addition, the NOX SIP call requires 22 
States and the District of Columbia to decrease emissions of 
NOX. The NOX SIP call also is based on a common 
core of factual findings and analyses concerning the transport of ozone 
and its precursors between the different States subject to the 
NOX SIP call. Finally, EPA has established uniform 
approvability criteria that would be applied to all States subject to 
the NOX SIP call. For these reasons, the Administrator has 
also determined that any final action regarding the NOX SIP 
call is of nationwide scope and effect for purposes of section 
307(b)(1). Thus, any petitions for review of final actions regarding 
the NOX SIP call must be filed in the Court of Appeals for 
the District of Columbia Circuit within 60 days from the date final 
action is published in the Federal Register.

H. Paperwork Reduction Act

    The EPA stated in the final NOX SIP call that an 
information collection request was pending. This action imposes no 
additional burdens beyond those imposed by the final NOX SIP 
call. Any issues relevant to satisfaction of the requirements of the 
Paperwork Reduction Act will be resolved during review and approval of 
that information collection request.
