ENVIRONMENTAL RELEASES

Scenario#: 1 Number of Release Sites: 1. 

Release Activity: MFGa

Release Description: WATER LANDFILL INCINER LAND/INCIN FUGITIVE

Total Releases: 800.00 0.00 7300.00 0.00 0.00

(kg/yr) (kg/yr) (kg/yr) (kg/yr) (kg/yr)

(kg/day) (kg/yr) (kg/yr) (kg/yr) (kg/day)

Remarks: Releases are to water or incineration. Water release is combination of 2 releases, assuming

overlap (50+150 kg/site/day). Incineration release is combination of 2 releases (200+7100

kg/yr) and is below assessment threshold after assuming 99.9% destruction.

Consumer use expected? No, consumer use is not expected.

Parameter Exp Based Persistent Exceedance value

Drinking (Surface) Water Dose (mg/kg/day) Yes N/A 6.43E-02

Fish Ingestion Dose (mg/kg/day) Yes N/A 1.94E-02

Inhalation Dose (mg/kg/day) No N/A 

Groundwater Dose (mg/kg/day) No N/A 

Surface Water Release after treatment (kg/yr) No N/A 

Total Release After Treatment (kg/yr) No N/A 

Consumer Exposure Dose? No 

**Exposure-based table developed without assuming overlap.

FATE TESTING RECOMMENDATIONS: On one or more of P-06-0263-4/6-7, first conduct ready biodeg

test. Then if eco concern persists, conduct activated sludge test (OECD 303A). Testing should probably be

done without the , which might confuse results because it is degradable.
