Supplementary Information

In today'sFederal Register, a proposed rule titled, “National Ambient Air Quality Standards for Particulate Matter,” with the same RIN as this correction (RIN 2060-AO47) was published. This correction corrects a typographical error in section X.A, Table 4 of the preamble. This correction will make a change to the summary of the potential costs and benefits of attaining several alternative PM 2.5 standards as presented in the Regulatory Impact Analysis (RIA). In NAAQS rulemaking, the RIA is done for informational purposes only, and the proposed decisions announced in today'sFederal Registerare not in any way based on consideration of the information or analyses in the RIA. Specifically, the net benefits presented in Table 4 (3% discount rate) for alternative PM 2.5 standard levels of 11/35 μg/m 3 (annual and 24-hour standards) were incorrectly identified as $8,900 to $2300 million in the proposed rule. The correct estimates are $8,900 to $23,000 million. Table 4 is corrected to read as follows:
