CONTACT: FOR FURTHER INFORMATION CONTACT: Brenda Millar (MD-14), Monitoring and Quality Assurance Group, Emissions Monitoring and Analysis Division, Environmental Protection Agency, Research Triangle Park, North Carolina 27711, Telephone (919) 541-4036, e-mail: millar.brenda@epamail.epa.gov. ACTION: ACTION: Final rule; correction. SUMMARY: SUMMARY: The EPA is making minor clarification and/or corrections to the final rules revising 40 CFR parts 50, 53, and 58 published on July 18, 1997. WORD COUNT: 1,889 TEXT: SUPPLEMENTARY INFORMATION: On July 18, 1997, EPA revised the national ambient air quality standards for particulate matter set forth in 40 CFR part 50 by, among other things, establishing provisions for particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers (PM sub 2.5) as measured by a new reference method or by an equivalent method. On the same day, EPA revised 40 CFR part 53 to set forth criteria for designation of candidate instruments as reference or equivalent methods for PM sub 2.5; it also revised 40 CFR part 58 to establish air quality monitoring, data reporting, and surveillance requirements for PM sub 2.5 and revise such requirements for particles with an aerodynamic diameter less than or equal to a nominal 10 micrometers PM sub 10). A review of the document resulted in the identification of a number of minor errors which this notice is correcting. Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a "significant regulatory action" and, is therefore not subject to review by the office of Management and Budget. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described in the Unfunded Mandates Reform Act of 1995 (P.L. 104-4), or require prior consultation with State officials as specified by Executive Order 12875 (58 FR 58093, October 28, 1993), or involve special consideration of environmental justice related issues as required by Executive Order 12898 (59 FR 7629, February 16, 1994). Because this action is not subject to notice-and-comment requirements under the Administrative Procedure Act or any other statute, it is not subject to the provisions of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business Regulatory Enforcement Fairness Act of 1996, EPA submitted a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives and the Comptroller General of the General Accounting Office prior to publication of this rule in today's Federal Register. This rule is not a "major rule" as defined by 5 U.S.C. 8094(2).
