Regulatory Impact Analyses

EPA develops Regulatory Impact Analyses (RIAs) to support the development of national air pollution regulations. RIAs contain descriptions of the potential social benefits and social costs of a regulation, including those that cannot be quantified in monetary terms and a determination of the potential net benefits of the rule including an evaluation of the effects that are not monetarily quantified. Typically, an RIA is structured similarly to an EIA, except that a benefits analysis of the rule is included along with an estimation of the net benefits. Further details about regulatory impact analyses completed by OAQPS can be found in Section 2 of Chapter 2 of the OAPQS Economic Analysis Resource Document.

Below is a list of industries for which RIAs were developed. The RIAs are available in PDF format (unless otherwise noted) and can be downloaded by clicking on the links below.

Final National Ambient Air Quality Standard for SO2

As it does with all major rules, EPA conducted a benefits and costs analysis of the national air quality standard (NAAQS) for SO2, which the Agency finalized on June 2, 2010. This regulatory impact analysis is designed to inform the public and state, local, and tribal governments about the potential costs and benefits of implementing these important air quality standards. It is not a part of the standard selection process.

Final National Ambient Air Quality Standard for Nitrogen Dioxide

As it does with all major rules, EPA conducted a benefits and costs analysis of the national air quality standard (NAAQS) for nitrogen dioxide, which the Agency finalized on January 22, 2010. This regulatory impact analysis is designed to inform the public and state, local, and tribal governments about the potential costs and benefits of implementing these important air quality standards. It is not a part of the standard selection process.

Reconsideration of National Ambient Air Quality Standard for Ozone
1-12-2010
As it does with all major rules, EPA conducted a benefits and costs analysis of the Reconsideration of the 2008 Ozone National Ambient Air Quality Standard (NAAQS), which the Agency proposed on January 6, 2010. This regulatory impact analysis is designed to inform the public and state, local, and tribal governments about the potential costs and benefits of implementing these important air quality standards. It is not a part of the standard selection process.

National Ambient Air Quality Standard for Sulfur Dioxide
11-18-2009
As it does with all major rules, EPA conducted a benefits and costs analysis of the national air quality standard for sulfur dioxide pollution, which the Agency proposed on November 16, 2009. This regulatory impact analysis is designed to inform the public and state, local, and tribal governments about the potential costs and benefits of implementing these important air quality standards. It is not a part of the standard selection process.

2008 National Ambient Air Quality Standard for Lead
10-16-2008
As it does with all major rules, EPA conducted a benefits and costs analysis of the national air quality standard for lead pollution, which the Agency strengthened on October 15, 2008. This regulatory impact analysis is designed to inform the public and state, local, and tribal governments about the potential costs and benefits of implementing these important air quality standards. It is not a part of the standard selection process.

2008 National Ambient Air Quality Standards for Ground-Level Ozone
3-13-2008
As it does with all major rules, EPA conducted an illustrative analysis of the potential costs and human health benefits of nationally attaining alternative ozone standards. The estimates are calculated incremental to a 2020 baseline that incorporates air quality improvements achieved through the projected implementation of existing regulations and full attainment of the existing ozone National Ambient Air Quality Standards (NAAQS)and the particulate matter (PM) NAAQS promulgated in September 2006. This regulatory impact analysis is designed to inform the public and states about the potential costs and benefits of implementing the new air quality standard. It is not a part of the standard selection process.

2006 National Ambient Air Quality Standards for Particle Pollution
10-6-2006
As it does with all major rules, EPA conducted a benefits and costs analysis of the national air quality standards for particle pollution, which the Agency strengthened on Sept. 21, 2006. This regulatory impact analysis is designed to inform the public and states about the potential costs and benefits of implementing these important air quality standards. It is not a part of the standard selection process.

The Expert Elicitation
As part of the Regulatory Impact Analysis, EPA sought the opinions of outside experts to support the characterization of uncertainty associated with reductions in exposure to particle pollution. As recommended by the National Academy of Sciences, EPA is using expert judgment as part of an effort to better describe the uncertainties inherent in any benefits analysis. This report and its findings are intended solely for this purpose.
