Clean Air Interstate Rule, Acid Rain Program and Former NOx Budget Trading Program 2012 Progress Report

2012 Progress Reports

Each year EPA releases reports summarizing and evaluating progress under both the Clean Air Interstate Rule (CAIR) and the Acid Rain Program (ARP). These reports show the combined effect of the programs on power sector emissions of SO2 and NOx and the resulting benefits through 2012.

2012 ARP and CAIR at a Glance

CAIR and ARP Annual SO2 Emissions: 3.3 million tons (68 percent below 2005)

CAIR Ozone Season NOx Emissions: 514,000 tons (37 percent below 2005)

CAIR and ARP Annual NOx Emissions: 1.7 million tons (53 percent below 2005)

Compliance: Perfect compliance for all facilities reporting to the CAIR and ARP programs

The first report presents 2012 data on combined emission reductions and compliance results for CAIR and the ARP as well as some historic emissions data from the NOx Budget Trading Program (NBP). It includes state-level emission reductions and trends, emission monitoring information, compliance details and analysis of market activity.

The second report, available in early 2014, evaluates the effects of these emissions reductions programs through improvements in air quality. It summarizes significant benefits to human health, reductions in acid deposition, and trends in recovery from acidification in fresh water lakes and streams.
