EPA Analysis of the Proposed Clean Power Plan

On June 2, 2014, EPA proposed the Clean Power Plan. EPA analyzed the proposal using IPM (v5.13).

Supplemental Documentation for the proposed Clean Power Plan

You will need Adobe Acrobat Reader to view some of the files on this page. See EPA's About PDF page to learn more about PDF, and a link to the free Adobe Acrobat Reader.

To learn more about several modeling assumptions used as part of EPA's analysis of the Clean Power Plan (Carbon Pollution Guidelines for Existing Electric Generating Units) using the EPA v5.13 Base Case using Integrated Planning Model (IPM), see the EPA v5.13 Supplemental Documentation for the proposed Clean Power Plan (PDF). (11 pp, 86K)

This supplemental documentation complements more comprehensive modeling documentation available at EPA's Base Case v5.13 using IPM.

IPM Run Description

EPA Base Case for the proposed Clean Power Plan (Zip 100 MB)

Base case model run, including the national Title IV SO2 cap and trade program; NOX State Implementation Plan (SIP) Call regional ozone season cap and trade program; Mercury and Air Toxics Rule (MATS); the Clean Air Interstate Rule (CAIR); and settlements and state rules through 2013 impacting SO2, NOX, directly emitted PM, and CO2. This scenario represents conditions without the proposed Guidelines.

Option 1 - Regional (Zip 102.5 MB)

Illustrative Regional compliance scenario for Option 1.

Option 1 - State (Zip 102.5 MB)

Illustrative State compliance scenario for Option 1.

Option 2 - Regional (Zip 102.5 MB)

Illustrative Regional compliance scenario for Option 2.

Option 2 - State (Zip 102.5 MB)

Illustrative State compliance scenario for Option 2.

Block 1 & 2 - Regional (Zip 102.5 MB)

Illustrative Regional compliance for the two building block approach.

Block 1 & 2 - State (Zip 102.6 MB)

Illustrative State compliance for the two building block approach.

Note: On 6/12/14, EPA revised the state emission summary tables for each scenario above to correctly reflect CO2 emissions associated with generation from landfill gas and municipal solid waste, and also to summarize emissions from fossil fuel-fired EGUs in Indian country. Additionally, corrections were made to the "EnvironmentalMeasures" RPT file for the "Block 1 & 2 - State" scenario.
