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:

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.
