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

\*\ 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.
