In accordance with the SAP, the baseline soil samples were collected from 0-15 cm and analyzed
for radium-226 and -228, natural uranium and natural thorium. The corresponding U.S.
Environmental Protection Agency (EPA) analytical methods are EPA M901.1 for the two
radiums and EPA M 6020 (Inductively Coupled-Mass Spectroscopy) for natural uranium and
thorium.

Table 4.2 documents the results of the soil sampling. The soil sample results represent a baseline
to compare results for soil samples collected at similar locations and depth during the
construction, operational, and closure phases of the Upton Project. It is recognized that
topography and other features may change over time; however, some of the sample locations are
expected to remain intact.
