Availability of Documents for the Rulemaking for Certain States 
in the Ozone Transport Assessment Group Region

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

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

SUMMARY: This document announces the availability of various documents 
that relate to the notice of proposed rulemaking and supplemental 
notice of proposed rulemaking for the ozone transport rule. These 
documents have been, or shortly will be, placed in the docket for this 
rule, or have been made available on the EPA website.

DATES: Documents were placed in the docket on or about August 10, 1998.

ADDRESSES: Some of the documents have been placed in the docket for the 
ozone transport rule, Docket No. A-96-56, at the Air and Radiation 
Docket and Information Center (6102), US Environmental Protection 
Agency, 401 M Street SW, Room M-1500, Washington, DC 20460, telephone 
(202) 260-7548, and are available for viewing between 8:00 a.m. and 
4:00 p.m., Monday through Friday, excluding legal holidays. A 
reasonable fee may be

charged for copying. Other documents have been made available in 
electronic form at the following EPA websites: http://www.epa.gov/
scram001/regmodcenter/t28.htm and http://www.epa.gov/capi.

FOR FURTHER INFORMATION CONTACT: Questions concerning today's document 
should be addressed to Kimber Smith Scavo, Office of Air Quality 
Planning and Standards, Air Quality Strategies and Standards Division, 
MD-15, Research Triangle Park, NC 27711, telephone (919) 541-3354; e-
mail: [email protected].

SUPPLEMENTARY INFORMATION: The EPA published a notice of proposed 
rulemaking (NPR) dated November 7, 1997, ``Finding of Significant 
Contribution and Rulemaking for Certain States in the Ozone Transport 
Assessment Group Region for Purposes of Reducing Regional Transport of 
Ozone,'' (62 FR 60318). The EPA published a supplemental notice of 
proposed rulemaking (SNPR) dated May 11, 1998, ``Supplemental Notice 
for the 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 25902). This rulemaking 
may be referred to as the ozone transport rule, and has, more 
colloquially, been referred to as the NOx SIP Call or the 
OTAG SIP Call.
    When EPA published the NPR, EPA established a 120-day comment 
period, ending on March 9, 1998. The EPA received numerous comments 
that this period was not adequate, particularly for performing air 
quality modeling. By notice dated April 9, 1998 (63 FR 17349), EPA 
extended the comment period to the close of the comment period for the 
SNPR, which was June 25, 1998.
    Numerous States, industry groups, and others submitted air quality 
analyses to the docket during the initial and extended comment period. 
Commenters also submitted comments on a wide range of issues raised 
under the NPR and SNPR.
    In response to these comments, EPA has conducted additional air 
quality modeling analyses. The EPA is announcing today that information 
concerning these analyses was placed in the docket as of August 10, 
1998, or shortly thereafter. See Appendix A for a more detailed 
description of this modeling information.
    In addition, EPA has placed four additional sets of IPM run files 
at the http://www.epa.gov/capi web site, which provide the Agency's 
results of analysis of cap-and-trade options that EPA examined in 
developing the ozone transport rulemaking using the 1998 version of 
IPM. These files are described in Appendix B.
    The EPA has previously made other information publicly available on 
EPA's Technology Transfer Network (TTN) site or the http://www.epa.gov/
ttn/oarpg/otagsip web site (which, in effect, superseded the TTN site) 
or the http://www.epa.gov/capi web site. For example, EPA made 
available updated emissions inventory information on the TTN on or 
about February 3, 1998. See Appendix C for a list of documents already 
made available on the TTN or web site. The EPA indicated in the NPR 
that related documents could be found on the TTN or on other web sites 
(62 FR 60318).
    The EPA anticipates that the notice of final rulemaking will be 
signed in September 1998.
    In addition, the following documents have been, or will shortly be, 
placed in the docket.
    1. E.H. Pechan & Associates, Inc., ``Ozone Transport Rulemaking 
Non-Electricity Generating Unit Cost Analysis--Final Report,'' August 
1998.
    2. Documents evidencing the public availability of the IPM model 
and UAM-V: (i) Letter from Gary Vicinus, Executive Vice President, ICF 
Kaiser, to Paul M. Stolpman, Director, Office of Atmospheric Programs, 
U.S. EPA, July 22, 1998 (IPM); (ii) Excerpts from ``Analyzing Electric 
Power Generation Under the CAAA,'' Office of Air and Radiation, U.S. 
EPA (March 1998) (IPM); (iii) Letter from William F. Hunt, Jr., 
Director, Emissions Monitoring and Analyses Division, Office of Air 
Quality Planning and Standards, U.S. EPA to Andrea Bear Field, Esq., 
Hunton & Williams (April 15, 1998) (UAM-V).
    In addition, EPA anticipates placing the following document in the 
docket in the near future.
    a. Comparison of 8-hour model predictions and ambient 8-hour design 
values.
    EPA may place additional documents in the docket, and if EPA does 
so, EPA will announce their availability by posting a notice on the 
http://www.epa.gov/ttn/oarpg/otagsip web site.

    Dated: August 17, 1998.
Robert D. Brenner,
Acting Director, Office of Air Quality Planning and Standards.

Appendix B--IPM Runs

    EPA has placed four additional sets of IPM run files at the http:/
www.epa.gov/capi web site, which provide the Agency's results of 
analysis of cap-and-trade options that EPA examined in developing the 
Ozone Transport Rulemaking using the 1998 version of IPM. These options 
are: 0.25, 0.20, 0.15, and 0.12 (all which interstate trading); as well 
0.15 (with intrastate trading).
    The files are initially marked by a run number (e.g. ``SIPI'' is 
the alpha-numeric identifier of the Initial Base Case Run followed by a 
designation of the file type in abbreviated form (e.g. ``CAR'' for 
capacity available report) and a run year (e.g T05 for 2005), if 
appropriate). They are ``zip'' (compressed) files, which can be 
``unzipped'' (made ready for review with a text editor) using Pkunzip 
software. Text files can be directly reviewed using Word Perfect and 
other word processing software. On file, containing unit-specific 
emissions projections, is in Microsoft Excel `97 format. The other 
files can be reviewed by using any good text editor. EPA uses the LIST 
utility for this purpose, but several others are available.
    EPA recommends having on hand its Analyzing Electric Power 
Generation under the CAAA, March 1998, and the Supplemental Ozone 
Transport Rulemaking Regulatory Analysis, 1998, when reviewing the 
results. It is important to recognize that the costs in the IPM runs 
are in 1997 dollars, which EPA converted to 1990 dollars.

Appendix C--Information Available on TTN or Web Site

    The following describes documents that, at various times during the 
course of this rulemaking, EPA has made available on the TTN or the 
http://www.epa.gov/ttn/oarpg/otagsip or http://www.epa.gov/capi web
