Overview of Technical Support Document

This Technical Support Document (TSD) details the data, tools and methods that EPA used to calculate the benefit per ton of PM_2.5 precursor emissions reduced from 21 industrial and area emission sectors. In January of 2023, EPA updated this page to:

• Reflect an updated version of the TSD that reports benefit per-ton values estimated using concentration-response parameters consistent with the Regulatory Impact Analysis for the proposed Particulate Matter National Ambient Air Quality Standards.
• Report updated Electricity Generating Unit benefit per-ton values quantified using updated air quality modeling simulations.

• Estimating the Benefit per Ton of Reducing PM2.5 and Ozone Precursors from 21 Sectors (pdf) (5.15 MB, September 18 2023)
• Estimating the Benefit per Ton of Reducing PM2.5 Precursors from 17 Sectors (Archive of 2018 TSD) (pdf) (6.01 MB, February, 2018)
