The following discussion is an explanation of each proposed sampling requirement. Loadout Wells No. 1, 2, 3, and Upstream and Downstream Roaring Fork River: _ ;; Snowmass proposes to cease all field and laboratory monitoring sj requirements at the unit train loadout facility. Five years of sampling have shown that the loadout has had no impact on the local surface or groundwater.
