National Ambient Air Quality Standards for Particulate Matter and 
Revised Requirements for Designation of Reference and Equivalent 
Methods for PM2.5 and Ambient Air Quality Surveillance for 
Particulate Matter; Correction

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; correction.

-----------------------------------------------------------------------

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.

DATES: Effective on February 17, 1998.

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: [email protected].

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 (PM2.5) 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 
PM2.5; it also revised 40 CFR part 58 to establish air 
quality monitoring, data reporting, and surveillance requirements for 
PM2.5 and revise such requirements for particles with an 
aerodynamic diameter less than or equal to a nominal 10 micrometers 
PM10). 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).
