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
The 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
The EPA has placed the information described below in the Proposed Transport Rule docket EPA-HQ-OAR-2009-0491.
- An updated version of NEEDS (v4.10). This database provides unit level characteristics of the electric generating units (EGUs) included in the IPM modeling. This includes both units affected by the Proposed Transport Rule and other EGUs (e.g. fossil-fired units smaller than 25 MWe, non-fossil-fired units, and fossil-fired units 25 MWe or greater in States not subject to the Proposed Transport Rule).
- User Guide to NEEDS v4.10.
- Detailed documentation of the IPM v4.10.
- New base case modeling run results with the updated IPM platform (v4.10): Summary Reports (for 2012, 2015, 2020, 2030) and unit level parsed file for 2012 (this modeling run is analogous to the base case run used to support the air quality modeling that determined which States significantly contributed to non-attainment or interference with maintenance in the Proposed Transport Rule).
- New policy case modeling run (identified as “TR SB Limited Trading”) with the updated IPM platform (v4.10): Summary Reports (for 2012, 2015, 2020, 2030) and unit level parsed file for 2014 (this modeling run is analogous to the preferred policy option run in the Proposed Transport Rule).
- New base case run results with the updated IPM platform (v4.10), as described above, except with the Energy Information Administration's Annual Energy Outlook (AEO) 2010 gas resource assumptions: Summary Reports (for 2012, 2015, 2020, 2030) and unit level parsed file for 2012.
- New policy case (identified as “TR SB Limited Trading”) with the updated IPM platform (v4.10), as described above, except with AEO 2010 gas resource assumptions: Summary Reports (for 2012, 2015, 2020, 2030) and unit level parsed file for 2014.
These policy runs include the same State-level caps that EPA modeled in the Proposed Transport Rule. The caps have not been modified to account for any changes that the new modeling might suggest; they are merely provided for informational purposes to allow commenters to understand the impact that changes in the model platform have on the projected impacts of the caps.
- User Guide to IPM v4.10 output files (system summary report and parsed files).
- A description of how to build an alternative gas resource assumption input for modeling (an intermediate option between AEO 2010 and EPA gas resource assumptions).
- A summary of other planned input updates to be implemented in the final rulemaking (further described below).
EPA proposes to use this version of the IPM model in the final Transport Rule, modified to address any comments that EPA receives as part of the transport rulemaking effort and other power sector analysis. Changes from the projections relied on in the proposed rule, from using an updated model, could impact the final rulemaking in a number of ways including, but not limited to:
1. Changing emission projections that were used to determine which downwind areas have air quality concerns (i.e., non-attainment or maintenance) absent this rulemaking and to determine which States contribute to those problems.
2. Changing cost and emission projections used in the multi-factor test to determine the amount of emissions that represent significant contribution.
EPA believes that the assumptions regarding natural gas resources in the primary IPM v4.10 base case are the appropriate ones to use. EPA is however providing information on an alternative set of assumptions (AEO 2010), as well as a third way that gas price assumptions could be developed. EPA requests comment on the appropriate natural gas assumptions to use.
EPA intends to update the NOX rates for fossil-fuel fired units in the final rule to reflect the more recent 2009 data. IPM v4.10 and the previous version of IPM used for the Proposed Transport Rule analysis relied on 2007 unit level NOX rates. The updated NOX rates will more Start Printed Page 53615accurately portray the unit level control installations that have occurred at power plants during the past several years. In general, about 25% of coal plants have a 2009 NOX rate that reflects a change from the 2007 that is greater than 0.1 lb/mmbtu and 10% of the 2007 value. The 2009 unit level data can be retrieved from EPA's Data and Maps at http://camddataandmaps.epa.gov/gdm/.
EPA also intends to update information related to new units, new installation of pollution controls, and planned retirements. Information on changes in these areas that EPA believes have happened since IPM v4.10 version of the model has been finalized is also included in the docket.
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.Start Signature
