Correction
In proposed rule document 2023-27758, appearing on pages 88315-
88336 in the issue of Thursday, December 21, 2023, make the following
correction:
On page 88326, in the table titled ``Table 7: Alternative 1:
Dissolved Oxygen Criteria Expressed as Concentration (mg/L)'', the
table is corrected to appear as set forth below:
Table 7--Alternative 1: Dissolved Oxygen Criteria Expressed as Concentration
[mg/L]
----------------------------------------------------------------------------------------------------------------
Water
Season temperature Magnitude (mg/ Duration Exceedance frequency
([deg]C) L)
----------------------------------------------------------------------------------------------------------------
Spawning and Larval Development * 23.3 (14.7) * 5.6 (6.7) Daily Average........ 10% (12 Days
(March 1-June 30). Cumulative).
Juvenile Development (July 1- \+\ N/A 5.4 Daily Average........ 10% (12 Days
October 31). Cumulative).
\+\ N/A 6.1 Daily Average........ 50% (61 Days
Cumulative).
Overwintering (November 1-February * 12.4 (5.6) * 7.0 (8.3) Daily Average........ 10% (12 Days
28/29). Cumulative).
----------------------------------------------------------------------------------------------------------------
\*\ The 90th percentile of seasonal water temperature and corresponding criterion is used for the main estimate,
while the average water temperature and corresponding criterion is shown in parentheses.
\+\ Water temperature is not applicable during the Juvenile Development season because the criteria magnitudes
are derived from the EPA's Atlantic Sturgeon cohort model, described in section IV.C.1 of this preamble.
