Regulatory Impact Analyses (RIAs)

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. As it does with all major rules, EPA conducts benefits and costs analyses of each proposed or revised National Ambient Air Quality Standard (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.
