### 1 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation.

2 Release activities are from engineering report's Manuf acturing (Mfg), Processing (Proc) and Use release

activity labels.

Multiple release activities are combined in one exposure scenario if their releases occur at same location.

3 Exposure calculations are Acute Dose Rate (A DR), Lifetime Average Daily Dose (LADD), and

Probabilistic Dilution

Model (PDM). There may be one, two, or all three exposure calculations per exposure scenario.

CC is the aquatic concentration of concern.

4 This column displays concentration values for the 7Q 10 streamflow, which is defined as the average daily

streamflow

of the seven consecutive days of lowest flow within a ten year period.
