Analysis of the Proposed Federal Implementation Plan Addressing Regional Ozone Transport for the 2015 Ozone National Ambient Air Quality Standard
On February 28, 2022, EPA proposed CSAPR for the 2015 Ozone NAAQS. EPA's power sector analysis for this proposal uses EPA's Power Sector Modeling Platform v6 using IPM.
Documentation for the EPA's Power Sector Modeling Platform v6 using IPM:
For the power-sector analysis of CSAPR for the 2015 Ozone NAAQS, the EPA relied on the Summer 2021 reference case as the starting platform for its assessment of the CSAPR for the 2015 Ozone NAAQS.
Below is the Summer 2021 version of the National Energy Electric Data System (NEEDS) used for the final modeling for CSAPR for the 2015 Ozone NAAQS, as well as a link to the most recent version used in some of EPA’s Rule analysis. A link to the IPM v.6 documentation is also included. Versions of NEEDS and IPM documentation used in the Air Quality Modeling Base Case and can also be found in the docket for this rule.
- NEEDS Summer 2021 Reference Case (xlsx)
- NEEDS rev: 10-25-21 (xlsx) (Utilized in engineering analytics to capture updated EGU retirement status)
- EPA's IPM v6 Summer 2021 Reference Case Documentation
- Optional template to assist in submitting comments (xlsx) to EPA regarding NEEDS, as well as other inputs and outputs of EPA's Power Sector Modeling using the Integrated Planning Model. Please be sure to submit comments to the docket by the due date. See CSAPR for the 2015 Ozone NAAQS for more information on submitting comments
IPM Run Files
Download IPM run files for CSAPR for the 2015 Ozone NAAQS using the links in the table below. Click on the IPM run name in the first column of the table below to download a file. The files are posted in one of two formats, a zipped archive or an excel spreadsheet, and contain detailed IPM input and output files (i.e., .DAT, System Summary Report, .RPE, and RPT files) for the listed runs. Review the guide of IPM input and output files.
More detailed information on the modeling framework, specific scenarios, assumptions, and other important details of the analysis can be found in the Regulatory Impact Analysis (pdf) that accompanies CSAPR for the 2015 Ozone NAAQS.
| IPM Run Name | IPM Run Description |
|---|---|
| Air Quality Modeling Base Case (zip) | Model run used for the air quality modeling base case at steps 1 and 2, which includes the national Title IV SO2 cap-and-trade program; NOX SIP Call; the Cross-State Air Pollution trading programs, and settlements and state rules. It also includes key fleet updates regarding new units, retired units, and control retrofits that were known by Summer of 2021. |
| Proposed Policy Scenario (zip) |
This run assumes the emission control levels in upwind states at the stringency level considered in the FIP for 2015 Ozone NAAQS, to inform air quality modeling projections and the RIA benefit-cost analysis. |
