As required under Executive Orders 12866 and 13563, 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. RIA documents are listed below, organized by:

RIAs for National Ambient Air Quality Standard (NAAQS)
Below is a list of RIAs for National Ambient Air Quality Standards (NAAQS). As it does with all major rules, EPA conducts benefits and costs analyses of each proposed or revised NAAQS. These regulatory impact analyses are designed to inform the public and state, local, and tribal governments about the potential costs and benefits of implementing these important air quality standards. NAAQS RIAs are not a part of the standard selection process. The NAAQS RIAs are available in PDF format and can be downloaded by clicking on the links below.

Guidance Relevant to Preparing RIAs
| OAQPS Economic Analysis Resource Document |
|---|
| Note that this document is dated and we are currently considering steps to bring it up to date. The purpose of this document is to serve as a resource for EPA staff and others for understanding and performing economic analyses. This document should not be interpreted as guidance that will be followed exactly by EPA in its analyses. Each analysis performed by EPA presents unique features and hence this guidance is only advisory in nature.
