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

2 Release activities are from engineering report's Manufacturing (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 (ADR), Lifetime Average Daily Dose (LADD), and Probabili stic

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

aquatic concentration of concern.9/19/12 Page 2 of 60

4 This column displays concentration values for the 7Q10 streamflow, which is defined as the average da ily

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