a. Acceptable soil concentration for 15 mrem/yr above background exposure and residential land use with 50 years of institutional control of the site. This Goal applies to areas other than the Former Hazardous Waste Management Facility.

b. Acceptable soil concentration for 15 mrem/yr above background exposure and industrial land use with 50 years of institutional control and residential land use with 100 years of institutional control of the site. This Goal applies to the Former Hazardous Waste Management Facility.

c. The strontium-90 goal is based on an evaluation of groundwater impacts. It is also protective of residential and industrial use.

d. DOE Order 5400.5 Radiation Protection of the Public and the Environment. Also, commonly used by the Environmental Protection Agency.

e. In addition to the radionuclide specific levels, a post remediation sampling and a dose assessment will be performed to ensure that the dose from the remaining concentrations of all radionuclides present is less than 15 mrem/yr above background considering 50 years of institutional control for the selected land use.

Radionuclide^e	Soil Cleanup Level Residential Land Use (pCi/g)	Soil Cleanup Level Industrial Land Use (pCi/g)
Cesium-137	23^a	67^b
Strontium-90	15^c	15^c
Radium-226	5^d	5^d
