C1-2023-27758. Water Quality Standards To Protect Aquatic Life in the Delaware River

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]

Season	Water temperature (°C)	Magnitude (mg/L)	Duration	Exceedance frequency
Spawning and Larval Development (March 1–June 30)	* 23.3 (14.7)	* 5.6 (6.7)	Daily Average	10% (12 Days Cumulative).
Juvenile Development (July 1–October 31)	+  N/A	5.4	Daily Average	10% (12 Days Cumulative).
	+  N/A	6.1	Daily Average	50% (61 Days Cumulative).
Overwintering (November 1–February 28/29)	* 12.4 (5.6)	* 7.0 (8.3)	Daily Average	10% (12 Days 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.
