Notice of Data Availability Supporting Federal Implementation
Plans To Reduce Interstate Transport of Fine Particulate Matter and
Ozone: Revisions to Emission Inventories
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of data availability (NODA).
-----------------------------------------------------------------------
SUMMARY: EPA is providing notice that it is supplementing the record
for the Proposed Transport Rule (75 FR 45210). EPA has placed in the
docket for the Proposed Transport Rule (Docket ID No. EPA-HQ-OAR-2009-
0491) additional information relevant to the rulemaking, including
updated emissions inventory data for 2005, 2012 and 2014 for several
stationary and mobile source inventory components. The data revisions
reflect new approaches to calculating emissions inventories for
specific source categories and related new information and models that
have become available since the emissions data were developed and
modeled for the proposed rule. EPA is requesting comment on the new
data provided in the docket and the proposed revisions identified in
this document. These data and revisions could impact the final rule,
although such impacts have not yet been quantified by EPA.

SUPPLEMENTARY INFORMATION: Detailed background information describing
the proposed rulemaking may be found in a previously published
document: Federal Implementation Plans to Reduce Interstate Transport
of Fine Particulate Matter and Ozone (Proposed Transport Rule);
Proposed Rule (75 FR 45210, August 2, 2010). The information placed in
the docket is also available for public review on the Web site for the
Transport Rule at http://www.epa.gov/airtransport/. If additional
relevant supporting information becomes available in the future, EPA
will place this information in the docket and make it available for
public review on this Web site. EPA is requesting comment only on the
data and revisions explicitly identified in this document. EPA
requested comment on all aspects of its emissions inventories in the
proposed Transport Rule. The comment period for that proposal closed on
October 1, 2010. EPA has not yet reviewed all comments received on the
proposed Transport Rule and notes that emission inventory data may be
further revised based on comments received on the proposed Transport
Rule or on additional information that becomes available before the
rule is finalized.
I. Additional Information on Submitting Comments
A. How can I help EPA ensure that my comments are reviewed quickly?
To expedite review of your comments by Agency staff, you are
encouraged to send a separate copy of your comments, in addition to the
copy you submit to the official docket, to: Alison Eyth, Air Quality
Assessment Division, USEPA, C339-02, 109 T.W. Alexander Drive, Research
Triangle Park, NC 27709; e-mail address: [email protected].
B. What should I consider as I prepare my comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through
EDOCKET, http://www.regulations.gov, or e-mail. Clearly mark the part
or all of the information that you claim to be CBI. For CBI information
in a disk or CD-ROM that you mail to the EPA docket office specified in
the Instructions, mark the outside of the disk or CD-ROM as CBI and
then identify electronically within the disk or CD-ROM the specific
information that is claimed as CBI. In addition to one complete version
of the comment that includes information claimed as CBI, a copy of the
comment that does not contain the information claimed as CBI must be
submitted for inclusion in the public docket. Information so marked
will not be disclosed except in accordance with procedures set forth in
40 CFR part 2.
2. Tips for preparing your comments.
When submitting comments, remember to:
i. Identify the NODA by docket number and other identifying
information (subject heading, Federal Register date and page number).
ii. Follow directions. The Agency may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal Regulations (CFR) part or section number.
iii. Explain your comments, why you agree or disagree; suggest
alternatives and substitute language for your requested changes.
iv. Describe any assumptions and provide any technical information
and/or data that you used.
v. If you estimate potential costs or burdens, explain how you
arrived at your estimate in sufficient detail to allow for it to be
reproduced.
vi. Provide specific examples to illustrate your concerns, and
suggest alternatives.
vii. Explain your views as clearly as possible, avoiding the use of
profanity or personal threats.
viii. Make sure to submit your comments by the comment period
deadline identified.
II. Web Site for Rulemaking Information
EPA has previously established a Web site for the proposed
rulemaking at http://www.epa.gov/airtransport. The Web site includes
the proposed rulemaking actions and other related information that the
public may find useful in addition to a link to this NODA.
III. New Information Placed in the Docket
EPA requests comment on the information described below that has
been added to the proposed Transport Rule docket: EPA-HQ-OAR-2009-0491.
Revised 2012 and 2014 projected non-electric generating
units (EGU) emissions for the cement industry, including new units and
facilities and closures; and for 2014, only expected facility changes
as provided by the Industrial Sector Integrated Solutions model as
described by the National Emission Standards for Hazardous Air
Pollutants From the Portland Cement Manufacturing Industry, and
Standards of Performance for Portland Cement Plants, September 9, 2010
(75 FR 54969).
Revised 2012 and 2014 projected emissions from the non-EGU
point and nonpoint emissions sectors to reflect emissions reductions
resulting from the National Emission Standards for Hazardous Air
Pollutants for Reciprocating Internal Combustion Engines, August 20,
2010 (75 FR 51570).
Revised 2012 and 2014 non-EGU point and nonpoint projected
emissions to reflect controls required by the New York State
Implementation Plan.
Revised 2012 and 2014 nonpoint emissions to reflect
improved information on the oil and gas production sector in Texas and
Oklahoma.
Revised spatial surrogate used to allocate county-level
oil and gas emissions into grid cells for 2005, 2012, and 2014.
Revised temporal allocation for the nonpoint fugitive dust
emissions sector.
Revised allocation of volatile organic compounds to the
species used by the air quality modeling for headspace vapor associated
with the nonroad mobile emissions sector.
Expanded summary spreadsheet for point sources to add
total particulate matter less than 2.5 microns (PM2.5)
emissions split into a filterable and condensable portion of
PM2.5 for each
[[Page 66057]]
facility. This spreadsheet does not include the other changes listed
above that affect point sources. Documentation is provided in the
spreadsheet on the location of the data used for computing the
condensable PM2.5 emissions in the 2005 point inventory.
Additionally, EPA seeks comment on whether or not to revise
projected non-EGU emissions inventories for 2014 to reflect sulfur
dioxide (SO2) and PM2.5 reductions from the
proposed National Emissions Standards for Hazardous Air Pollutants for
Major Sources: Industrial, Commercial, and Institutional Boilers and
Process Heaters (75 FR 32006), hereafter referred to as the ``Major
Source Boiler Rule.'' The information included in the docket reflects
reductions that would be expected if the rule were finalized as
proposed. If the projected reductions associated with the final Major
Source Boiler Rule were to differ from the projected reductions
associated with the proposal, EPA would use the projections for the
final rule if they become available in time for use in EPA's modeling
for the final Transport Rule.
In addition, EPA requests comment on the following modified
approaches to calculating emissions inventories that we intend to use
in the modeling for the final Transport Rule.
EPA proposes to use the latest public release of the Motor
Vehicle Emissions Simulator (MOVES) (http://www.epa.gov/otaq/models/moves/index.htm) to estimate on-road mobile emissions data in 2005,
2012, and 2014 for all modeled pollutants and emissions processes in
all States, except California. Future-year vehicle miles traveled will
be revised from proposal to reflect the latest available data. This
approach differs from the proposal in the following significant ways:
(1) EPA will use a newer version of MOVES which has different emissions
values from the version of MOVES used for the proposal; (2) EPA will
use MOVES instead of the Mobile Source Emission Factor Model version
6.2 (MOBILE6) for diesel vehicles and motorcycles; (3) EPA will use
MOVES instead of MOBILE6 for additional pollutants, including
SO2, ammonia (NH3), and PM2.5 from
brake and tire wear; (4) the revised MOVES reflects NH3
decreases in future years that were not reflected by MOBILE6; and, (5)
EPA will use actual MOVES runs for 2012 and 2014 rather than scaling
2005 MOVES emissions. With the exception of these changes, EPA intends
to continue to apply MOVES using the same approaches described in the
Emission Inventory Technical Support Document released with the
Transport Rule proposal (http://www.epa.gov/airquality/transport/pdfs/TR_Proposal_Emissions_TSD.pdf; Section 3.3.1). The revised approach
will be similar to the approach described in the Technical Support
Document for the proposed rule in the following key ways: (1) EPA will
allocate State-total MOVES results to counties by pollutant and process
using results from MOBILE6 and the National Mobile Inventory Model; and
(2) EPA will use MOVES defaults rather than State-specific or county-
specific MOVES inputs.
EPA proposes to use the final projections from 2002 to
2005, 2012, and 2014 emissions for the category 3 commercial marine
sector to reflect the final category 3 commercial marine Emissions
Control Area proposal to the International Maritime Organization (EPA-
420-F-10-041, August 2010).
EPA proposes to reduce the boundaries used to allocate
category 3 commercial marine emissions to States from 200 nautical
miles to reflect State waters (3-10 nautical miles) based on Mineral
Management Service State-federal boundary data consistent with
approaches used for the 2005 and 2008 National Emissions Inventories.
EPA proposes to include the data revisions identified
above in the final Transport Rule, modified to address any comments
that EPA receives as part of the transport rulemaking effort. Changes
in the emissions data could impact the final rulemaking in a number of
ways including, but not limited to:
1. Changing base year emissions and emissions projections could
impact which downwind areas have projected air quality concerns absent
this rulemaking (i.e., non-attainment or maintenance).
2. Changing emissions projections could impact EPA assessment of
which States contribute to those problems.
Between now and the time that EPA finalizes the Transport Rule,
additional information used to support the final transport rulemaking
may be placed in the docket. As noted above, EPA is requesting comment
only on the data and revisions explicitly identified in this document.
EPA requested comment on all aspects of its emissions inventories in
the proposed Transport Rule. The comment period for that proposal
closed on October 1, 2010. EPA has not yet reviewed all comments
received on the proposed Transport Rule and notes that emission
inventory data may be further revised based on comments received on the
proposed Transport Rule or on additional information that becomes
available before the rule is finalized.
