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 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 concen tration values for the 7Q10 streamflow, which is defined as the average daily

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

Note: The general Agency guidance for assessing s hort

less than 24 hours that occurs no more frequently than monthly) is to treat such events as independent, acute

exposures rather than as chronic exposure. (Methods for Exposure
