1 Exposure scenario titles consi st 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 scenari o 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 concentration values for the 7Q10 streamflow, which is defin ed as the average streamflow

the 7 consecutive days of lowest flow within a 10 year period.

Note: The general Agency guidance for assessing short

- term, infrequent events (for most chemicals, an exposure of

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
