IPM Analysis of the Final Mercury and Air Toxics

Standards (MATS)

On December 16, 2011, EPA signed a Notice of Final Rulemaking for the

Mercury and Air Toxics Standards (MATS). EPA analyzed the impact of

MATS on the U.S. electric power sector using version 4.10_MATS of the

Integrated Planning Model (IPM). From this page you can download

documentation for IPM v4.10_MATS, the "NEEDS" database of electric

generation unit records used in the modeling, and the IPM run results files.

IPM Analysis of the proposed Toxics Rule on the U.S. electric power

sector.

Documentation: Updates to EPA Base Case v4.10_MATS

EPA Base Case v4.10_MATS is the IPM version that EPA used to analyze the Final MATS. To learn

more about the v4.10_MATS assumptions, see the link below. EPA Base Case v4.10_MATS builds

on the last major update to the IPM model, EPA Base Case v4.10, as well as two subsequent

updates: Updates to EPA Base Case v410_PTox and Updates to EPA Base Case

v4.10_FTransport.

Please note that the documentation for v4.10_MATS (presenting new modeling capabilities and

updated input assumptions) supplements the more comprehensive documentation of EPA's IPM

Base Case v4.10 and the two updates to that document noted above.

National Electric Energy Data System (NEEDS) v4.10_MATS

The National Electric Energy Data System or "NEEDS" database contains the generation unit

records used to construct the "model" plants that represent existing and planned/committed units

in EPA modeling applications of IPM. NEEDS includes basic geographic, operating, air emissions,

and other data on these generating units. The following link provides access to the updated

version of NEEDS used in modeling the proposed Toxics Rule.
