Interim Response Activities Mitigation Decision Matrix. The Interim Response Activities Mitigation Decision Matrix shown in Table 1 provides a description of two prioritized Exposure Categories with a corresponding range of Mitigation Options. TABLE 1 Interim Response Activities Mitigation Decision Matrix The Dow Chemical Company Exposure Category Exposure Category Description Mitigation Options Priority 1 Property presumed or determined to be impacted over 1,000 ppt TEQ proximate to a residence. Those residential properties identified through the above process where waters of the March 2004 flood event inundated, surrounded or approached the residence and those residential properties where it is otherwise known that the ATSDR action level is exceeded in soils proximate to the residence. Residential use, dioxin and furan concentrations in surface soil (0 to 1 inch and/or 0 to 8 inches for garden areas) above 1,000 ppt TEQ. Residential use includes properties with exposure potential that is similar to residential (e.g., schools, child care facilities, nursing homes, adult day care facilities). Mitigation options to be offered to the property owner(s): • Education and outreach • Provide temporary exposure barriers for exposed or poorly covered areas used by the owner : o Cover (e.g., sod, soil, raised garden bed, raised area, paving, mulch) o Augment existing cover o Provide paving or cover at entryways to minimize track-in of contaminated soils. • House cleaning, including cleaning of carpeting , interior ductwork, and other surfaces where contaminants may potentially accumulate • Identification of affected areas (known through sampling and or identification of flooding) by means agreeable to resident [e.g., flagging, marked aerial photographs]) • Monitoring, maintenance, and restoration of mitigation measures as necessary. • Removal of water and deposited sediment and soil after flooding events • Other reasonable mitigation measures identified and agreed to by property owner(s) based on their uses of the property Exposure
