[FRL-6439-5]
Notice of Availability of Unit-Specific Information for Affected
Sources Under Section 126 and Proposed Section 110 FIP Rulemakings;
Reopening of Comment Period
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of data availability and request for comment; reopening
of comment period.
-----------------------------------------------------------------------
SUMMARY: EPA is reopening the comment period for the Notice of
Availability of Unit-Specific Information for Affected Sources Under
Section 126 and Proposed Section 110
[[Page 50042]]
FIP Rulemakings, published on August 9, 1999, regarding three sets of
data related to the proposed Federal NOX Budget Trading
Program. The August 9, 1999 notice established a 30-day comment period,
which ended on September 8, 1999. EPA is reopening the comment period
for all information contained within the data files, which were
referenced by the notice, to September 24, 1999. In particular, EPA
continues to solicit comment on 1997 heat input data for all Electric
Generating Units (EGUs), including those EGUs reporting under EPA's
Acid Rain Program.
We may use the data in the data files in the future to allocate
NOX allowances under the Federal NOX Budget
Trading Program. We proposed the program in rulemakings under Sections
126 and 110 of the Clean Air Act. The program aims to reduce interstate
transport of ozone by controlling emissions of nitrogen oxides
(NOX). NOX emissions significantly contribute to
violations of the National Ambient Air Quality Standard for ozone in
downwind states.
Readers should note that we will only consider comments about the
data discussed in this notice and the August 9, 1999 notice. We are not
soliciting comments on any other topic. In particular, we are not
reopening the comment period for the October 21, 1998 proposed rule on
the Section 126 rulemaking or the October 21, 1998 proposed rule on the
Section 110 Federal Implementation Plans (FIPs) through this Notice of
Data Availability. Neither are we soliciting comments on inventory data
for 1995 and 1996 that we used to develop Statewide emission budgets.
DATES: The EPA is reopening the comment period to end on September 24,
1999.
ADDRESSES: Comments may be submitted to the Air and Radiation Docket
and Information Center (6102), Attention: Docket Nos. A-97-43 (section
126 rulemakings) and A-98-12 (section 110 FIP rulemakings), U.S.
Environmental Protection Agency, 401 M Street SW, room M-1500,
Washington, DC 20460, telephone (202) 260-7548. Identify your comments
with these docket numbers. Submit two originals and exact duplicates of
your comments to each docket. Please submit your comments on paper, not
in electronic format. We request this so that we do not receive
multiple versions of the same comment that might contradict each other.
Documents relevant to this action are available for inspection at
the Docket Office, at the above address, between 8:00 a.m. and 5:30
p.m., Monday though Friday, excluding legal holidays. A reasonable
copying fee may be charged for copying.
FOR FURTHER INFORMATION CONTACT: General questions concerning today's
action should be addressed to Margaret Sheppard, Acid Rain Division,
EPA, Mail Code 6204 J, 401 M Street SW, Washington DC, 20460; telephone
202-564-9163, email address [email protected]. For technical
questions concerning heat input data, contact Kevin Culligan at
telephone 202-564-9172, email address [email protected].

2. Why is EPA reopening the public comment period?
3. When are my comments due?
4. What data should I comment on?
5. What things is EPA not requesting comment on?
6. Where are the data files?
1. What Is Today's Action?
Today, we are reopening the public comment period on the August 9,
1999 notice of data availability (64 FR 43124), entitled ``Notice of
Availability of Unit-Specific Information for Affected Sources Under
Section 126 and Proposed Section 110 FIP Rulemakings.'' The public
comment period for that notice ended on September 8, 1999. Today's
notice reopens the public comment period through September 24, 1999.
In addition, we are emphasizing that you may comment on heat input
data for 1997 for units reporting under the Acid Rain Program, as well
as the other data in the files referenced in the August 9, 1999 notice.
For further information and background on the data referenced by
this notice and EPA's rulemakings related to NOX transport
under Sections 126 and 110 of the Clean Air Act, see the August 9, 1999
notice (64 FR 43124).
2. Why Is EPA Reopening the Public Comment Period?
Just before the September 8, 1999 deadline for submission of
comments, we received several requests to extend the public comment
period. Some commenters requested more time to understand potential
discrepancies between company records and the data in EPA's data files.
Further, although EPA has received comments on heat input data for 1997
for units reporting under the Acid Rain Program, some commenters said
that it was not clear whether there had been an opportunity to comment
on such heat input data.
EPA agrees that it may improve the quality of the data to provide
some additional time to compare the values with company records.
Further, EPA notes that many commenters submitted comments on heat
input data for 1997 for units under the Acid Rain Program in response
to the August 9, 1999 notice of data availability or prior notices.
However, because some commenters claim that they were unclear about
whether EPA was requesting comment on the 1997 heat input data, we
emphasize that they may comment on such data, in addition to the other
data in the data files.
Most commenters requesting an extension asked for a thirty-day
extension. We are instead reopening the public comment period for
approximately two weeks. Many of the commenters requesting the
extension are checking data (e.g., 1997 and 1998 heat input data) that
they previously reported to EPA or to the Energy Information
Administration (EIA). Under the Acid Rain Program, the designated
representative for the affected source has certified that the data
reported to EPA are accurate. The data we have provided for comment in
the data files differ from the original reports in that: (1) we
calculated heat input and electric generation values for the ozone
season for each year from hourly or monthly data in the reports to EPA
or EIA, and (2) we apportioned electric generation data for an entire
plant to individual units that would receive NOX allowance
allocations. Reopening the public comment period for approximately two
weeks will provide a reasonable, additional period for checking the
original reports and submitting any resulting comments. This also
provides a reasonable, additional period for commenters to submit any
other comments.
3. When Are My Comments Due?
Postmark your comments no later than Friday, September 24, 1999.
4. What Data Should I Comment On?
Comment on any data in the data files ``eguburn.txt,''
``egunonox.txt'' and ``nonegu.txt'' in the compressed file labeled
``allodata.zip''. We are particularly interested in comments that may
change data that we could use to determine NOX allowance
allocations under the Federal NOX Budget Trading Program.
These data include, among other things:
Electric generation data from EGUs from May through
September for the years 1995 through 1998.
[[Page 50043]]
Electric generation data from electric generators that do
not burn fuel from May through September for the years 1995 through
1998.
Nameplate capacity data for electric generators that do
not burn fuel.
Heat rate data for EGUs.
Heat input data for May through September for the years
1997 and 1998 for EGUs.
Heat input data for May through September for the year
1995 for non-EGUs. In addition, if you find that the heat input for
your non-EGU during May through September for the year 1995 is not
representative of your unit's operation over the last several years,
then you may comment and provide us heat input data for May through
September for the years 1996, 1997, and/or 1998.
See the section entitled ``What supporting documentation do I need to
provide with my comments?'' in the August 9, 1999 notice of data
availability for further details on information you should provide with
your comments.
If you have already submitted comments on the August 9, 1999 notice
of data availability, you may submit supplementary comments.
5. What Things Is EPA Not Requesting Comment On?
EPA is requesting comment only on the data in the data files
referenced here and in the August 9, 1999 notice of data availability.
We are not requesting comment on any other issue or data.
6. Where Are the Data Files?
The data files are available on the Regional Transport of Ozone
webpage at http://www.epa.gov/ttn/rto/. You will find links to the data
under the ``Related Documents and Data'' subheadings under the
``Transport FIPs'' and ``Section 126 Petitions'' headings on the
Regional Transport of Ozone webpage. Look for a WinZip file labeled ``a
WinZip file containing heat input and electric generation data that EPA
or States could use for determining NOx allowance allocations. EPA
requests comment on these data.'' In addition to the data files, the
WinZip file also contains a text file describing the fields in the data
files, ``readme.txt,'' and a text file describing EPA's method for
preparing the electric generation data, ``outmethd.txt''. In addition,
these data are in Docket Nos. A-97-43 (Section 126 rulemaking) and A-
98-12 (Section 110 FIP rulemaking).
