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:
BILLING CODE 6560-50-P
[[Page 2070]]
[GRAPHIC] [TIFF OMITTED] TP15JA97.000
[[Page 2071]]
3. On page 65862, replace Figure 1 with new Figure 1 which has
easier to read shading as follows:
[GRAPHIC] [TIFF OMITTED] TP15JA97.001
[[Page 2072]]
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:
BILLING CODE 6560-50-P
[[Page 2073]]
[GRAPHIC] [TIFF OMITTED] TP15JA97.002
[[Page 2074]]
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.''
