Proposed Requirements for Designation of Reference and Equivalent 
Methods for PM2.5 and Ambient Air Quality Surveillance for 
Particulate Matter

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule: correction.

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

SUMMARY: The EPA is correcting production errors in the printing of the 
proposed revisions to 40 CFR parts 53 and 58 (61 FR 65780) for 
particulate matter monitoring published on December 13, 1996.

FOR FURTHER INFORMATION CONTACT: Neil H. Frank at (919) 541-5560.

SUPPLEMENTARY INFORMATION: The EPA proposed revisions to 40 CFR parts 
53 and 58 (61 FR 65780) on December 13, 1996 to establish requirements 
for designation of reference and equivalent methods of PM2.5 and 
to establish ambient air quality monitoring requirements for 
particulate matter. A review of the notice resulted in the 
identification of a missing figure from Sec. 58.13 of part 58, text 
that was omitted, and two difficult to read figures from Appendix D to 
part 58. In addition, some minor errors were identified elsewhere. This 
notice presents the missing figure and text, reprints several hard to 
read figures, and makes the other corrections.

    Dated: January 7, 1997.
Richard D. Wilson,
Acting Assistant Administrator for Air and Radiation.

    The following corrections are made to FRL-5659-2, ``Proposed 
Requirements for Designation of Reference and Equivalent Methods for 
PM2.5 and Ambient Air Quality Surveillance for Particulate 
Matter'' published on December 13, 1996 (61 FR 65780).
    1. On page 65800, column 1, Sec. 53.9, revise ``Designation of a 
candidate method as a reference method or equivalent method shall be 
conditioned

[[Page 2069]]

on the applicant's * * *'' to read ``Designation of a candidate method 
as a reference method or equivalent method shall be conditional to the 
applicant's * * *''
    2. On page 65847, column 1, after paragraph (3), insert the 
following figure:

    3. On page 65862, replace Figure 1 with new Figure 1 which has 
easier to read shading as follows:

    4. On page 65862, column 1, the paragraph immediately following 
``2.8.2.1 Core Monitoring Stations for PM2.5'' should be identified as 
``2.8.2.1.1.''
    5. On page 65862, column 1, paragraph 2.8.2.1.2 change ``including 
at least one station in a population oriented area of expected maximum 
concentration; (b) At least one station in an area of poor air 
quality'' to ``including at least one station in a population oriented 
area of expected maximum concentration, and at least one station in an 
area of poor air quality'' and change ``(c) at least one additional 
core monitor'' to ``(b) at least one additional core monitor.''
    6. On page 65862, column 2, change paragraph ``2.8.1.1.4'' to 
``2.8.2.1.4.)
    7. On page 65869, replace Figure 5 with new Figure 5 which has 
easier to read shading as follows:

    8. Following page 65869, insert ``2.8.3.6 In Figure 6, areas of the 
State included within MPA's are shown within heavy solid lines. Two 
MPA's are illustrated. Areas in the State outside the MPA's will also 
include monitors, but this monitoring coverage may be limited. This 
portion of the State will also be represented by SAZ's (shown by areas 
enclosed within dotted lines). Monitors eligible for comparison to the 
NAAQS are indicated by ``X.'' The appropriate monitors within an SAZ 
would be averaged for comparison to the annual NAAQS and examined 
individually for comparison to the daily NAAQS. Other monitors are only 
eligible for comparison to the daily NAAQS. Both within the MPA's and 
in the remainder of the State, some special study monitors might not 
satisfy applicable Part 58 requirements or will not be included in the 
State Monitoring Plan and will not be eligible for comparison to the 
NAAQS. The latter may include SLAMS monitors designated to study 
regional transport or to support secondary NAAQS in unpopulated 
areas.''
