Abstract

This Butte Priority Soils Operable Unit (BPSOU) Insufficiently Reclaimed (IR) Site Evaluation Summary Report (SESR) presents results of soil sampling conducted on August 12, 2022, at the IR source area Butte Reclamation Evaluation System (BRES) No. 16 – Curry Site and adjacent areas (referred to herein as Site) within the BPSOU. The BPSOU Consent Decree (CD) required further evaluation of this IR Site since reclamation was conducted in 1991, prior to establishment of the Butte Hill Revegetation Specifications (BHRS) (EPA, 2020) and because the Site did not meet BRES requirements during the 2017 assessment performed by the Clark Fork Watershed Education Program, with oversight from the Environmental Protection Agency (EPA) (BSB, 2017). Further evaluation was conducted to determine if the Site meets or fails the BHRS requirements, poses a threat to human health, contributes metals-impacted sediment to existing or planned wet weather control features, or contributes to the degradation of surface water quality as described in the BPSOU CD, Appendix D, Attachment C Further Remedial Elements Scope of Work (FRESOW) (EPA, 2020).
