Reopening of Emissions Inventory Comment Periods for the Findings
of Significant Contribution and Rulemakings on Section 126 Petitions
and Federal Implementation Plans for Purposes of Reducing Interstate
Transport of Ozone
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of reopening of comment periods for emission inventory
inputs.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that EPA is reopening the comment
periods for emissions inventory revisions to the 2007 baseline sub-
inventory information for the proposed rulemakings concerning the Clean
Air Act section 126 petitions (the section 126 proposal) and the
Federal implementation plans (FIPs) for the purpose of reducing
interstate ozone transport. For both proposals, this includes
opportunity to comment on source-specific emission inventory data; for
the FIP proposal, it also includes the opportunity to comment on
vehicle miles traveled (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
comment periods remain closed for all other issues.
DATES: The EPA is reopening the comment periods for emissions inventory
revisions, ending on February 22, 1999. Comments must be postmarked by
the last day of the comment periods and sent directly to the Docket
Office listed in ADDRESSES (in duplicate form if possible). The EPA
strongly urges commenters to submit proposed changes to the inventories
of electric generating units (EGUs) greater than 25 megawatts (MWe) and
non-EGU boilers and turbines greater than 250 mmBtu/hr by January 25,
1999 to facilitate incorporation of any necessary changes into the
section 126 final rulemaking.

SUPPLEMENTARY INFORMATION: By notice dated September 30, 1998, EPA
proposed ``Findings of Significant Contribution and Rulemakings on
Section 126 Petitions and Federal Implementation Plans for Purposes of
Reducing Interstate Ozone Transport,'' (63 FR 52213). On October 21,
1998, EPA published longer, more detailed versions of these proposals
entitled ``Findings of Significant Contribution and Rulemaking on
Section 126 Petitions for Purposes of Reducing Interstate Ozone
Transport,'' (63 FR 56292), which may be referred to as the section 126
proposal; and ``Federal Implementation Plans to Reduce the Regional
Transport of Ozone,'' (63 FR 56394), which may be referred to as the
FIP proposal. These two proposals each had a comment period of 60 days,
which closed on November 30, 1998.
By notice dated October 27, 1998, EPA published the final
rulemaking, ``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.
Comment Period for Emission Inventory Revisions
In the final NOX SIP call, as described at 63 FR 57427,
EPA provided that the opportunity for source-specific inventory data
revisions would be available for the first 60 days of the 12-month
period between signature of the NOX SIP call and the
deadline for submission of the required SIP revisions (i.e., November
23, 1998). The EPA received numerous requests to allow more time to
accept revisions to source-specific inventory data used to establish
each State's base inventory and budget in the NOX SIP call
and to also allow revisions to VMT projections. The Agency is aware of
difficulties some States have had accessing the emission inventory data
bases. Therefore, in a separate notice (63 FR 71220; December 24,
1998), EPA extended this time period for source specific emissions
inventory revisions and also agreed to accept revisions to VMT
projections until February 22, 1999. Because the section 126 and FIP
proposals rely on the same emissions inventory information as the
NOX SIP call, EPA is today reopening the comment periods for
these actions specifically for emissions inventory revisions.
As specified in section III.F.5 of the final NOX SIP
call, no changes to an emissions inventory will be made unless
information is provided to corroborate and justify the need for the
requested modification. Commenters need to submit any suggested
inventory changes to the EPA Air and Radiation docket (A-97-43 for the
section 126 proposal, and A-98-12 for the FIP proposal) by February 22,
1999. Sources and other non-State commenters should also send a copy of
their comments concerning the inventory changes to their State air
pollution control agency. A courtesy copy of comments mailed to Greg
Stella at the address listed above would be appreciated in addition to
the formal submittal to the docket(s).
For a comment to be considered, the data submitted in the request
for modification must be submitted in electronic format (i.e.,
spreadsheet, data base, text file) and must be accompanied
[[Page 2417]]
by information to support the requested change. The EPA has identified
the specific data elements for each source sector that must be included
in the electronic file submitted with any data modification request.
For budget calculation purposes, emphasis should be on NOX
emissions, noting that other precursor emissions and modeling data are
necessary for final development of the modeling inventory.
However, in many cases, not all of the inventory information needs
to be corrected and resubmitted. For example, it may be the case that
source-specific NOX emission rates are incorrect, but all
stack and other emissions data are acceptable. In these cases, it is
not necessary to resubmit the entire inventory record data. Only source
identification information and additional data that require correction
need to be resubmitted. In those cases where the majority of the data
are incorrect or the submission is for a new, unaccounted for source,
complete files with all data fields outlined in section III.F.5 of the
final NOX SIP call must be submitted.
For those sources so indicated above, a simplified inventory
revision submittal is acceptable and must include the following
information:
Source sector needing revision,
Identification of the specific changes requested to the
inventory,
Reason for requested change,
All of the following sector-specific information in
electronic file format:
Electric Generating Units
Data on a source-specific basis including:

For the FIP action, EPA is also accepting comments 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. These comments must be on a county-level basis and must
include adequate evidence and explanation for any differences between
the input parameters used in the proposed FIP budgets and the input
parameters being proposed in the comments. Comments also must be
consistent with other State submittals, including SIPs, transportation
plans and conformity demonstrations, and other documents, or must
contain an explanation for the differences between the comments and
these other recent submittals and a plan to correct these other
submittals to make them consistent with the comments submitted in
response to this notice.
In the notice which extended the period for emissions inventory
revisions for the NOX SIP call (63 FR 71220; December 24,
1998), EPA also corrected Table III-1 and clarified how large EGUs and
large non-EGUs are defined. Those corrections and clarifications are
applicable and included by reference in the section 126 and FIP
rulemakings. That notice has been placed in the section 126 and FIP
rulemaking dockets.
Availability of Related Information
The official records for the section 126 and FIP rulemakings, as
well as the public versions (including comments and data submitted
electronically as described below), have been established under Docket
No. A-97-43 for the section 126 action and Docket No. A-98-12 for the
FIP action. The official record for the NOX SIP call has
