POST-INITIAL REVIEW EXPOSURE REPORT (IRExR)

Chemical ID: P-18-0320 Reviewer: Mottl/Childs/ND

This assessment is based on the Focus Ready Complete dated 11/5/2018.

The Fugitive Air release was refined and modeled with IIOAC (Integrated Indoor-Outdoor Air Calculator, version 1.0).

Remarks: Dose and concentration are at the fenceline (100 meters away from source). No releases to Stack Air. Exposure from predicted environmental incineration release(s) was not assessed for the acute and chronic scenarios, as

they are expected to be negligible. Specific Air releases from the Engineering Report were modeled using the Fugitive Air option.

Default Assumptions: USE – Coarse (exposure used the particulate coarse setting to reflect a droplet/mist-type exposure, based on the

Engineering report)

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 concentration 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.
