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. |
