40 CFR Part 52

[EPA-R01-OAR-2020-0132; FRL-10007-96-Region1]

Air Plan Approval and Air Quality Designation; Connecticut; 
Determination of Clean Data for the 2008 8-Hour Ozone Standard for the 
Greater Connecticut Area; Correction

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; correction.

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

SUMMARY: This document corrects information displayed in a Table within 
the proposed rule published in the Federal Register on March 27, 2020. 
The Environmental Protection Agency (EPA) published a proposed rule 
determining that the Greater Connecticut Serious 8-hour ozone 
nonattainment area had attained the 2008 8-hour National Ambient Air 
Quality Standard (NAAQS) for ozone.

DATES: April 20, 2020.

FOR FURTHER INFORMATION CONTACT: Elizabeth Townsend, Air Quality 
Branch, U.S. Environmental Protection Agency, EPA Region 1, 5 Post 
Office Square, Suite 100 (Mail code: 05-2), Boston, MA 02109-3912, 
telephone number: (617) 918-1614, email townsend.elizabeth@epa.gov.

SUPPLEMENTARY INFORMATION: The EPA issued a proposed rule in the 
Federal Register on March 27, 2020 (85 FR 17301). There was an error in 
``Table 1'' contained within section ``II. Analysis of Air Quality 
Data'' of the March 27, 2020 proposed rule. The table erroneously 
listed three data points in the ``2016'' column for Abington, Cornwall, 
and East Hartford. Table 1 should have listed the fourth-high 8-hour 
ozone average concentration in 2016 for Abington as 0.067, Cornwall as 
0.074, and East Hartford as 0.072. The corrected data reflects EPA's 
concurrence on Connecticut's exceptional event demonstrations from the 
2016 Fort McMurray wildfire that caused elevated ozone levels 
throughout Connecticut. The fourth-high 8-hour ozone average 
concentrations exceeded the 2008 8-hour NAAQS at the Cornwall 
monitoring station, and elevated ozone concentrations at the Abington 
and East Hartford stations. This corrective action does not affect the 
calculated design values in Table 2, which determine if an area is 
meeting the NAAQS. This correction notice does not otherwise change the 
remaining portions of the March 27, 2020 notice of proposed rulemaking.

Correction

    In FR Doc. 2020-06273 appearing on pages 17301-17303 in the Federal 
Register of Friday, March 27, 2020, the following correction is made:
    On page 17302, in Table 1, under the heading entitled ``2016'' 
remove the text ``0.074'' associated with Abington and replace the text 
with ``0.067'', remove the text ``0.078'' associated with Cornwall and 
replace the text with ``0.074'', and remove the text ``0.075'' 
associated with East Hartford and replace the text with ``0.072''. The 
complete corrected table is below:
