Abstract
This Butte Priority Soils Operable Unit (BPSOU) Backfill and Cover Material Quality Assurance Project Plan (QAPP) provides the procedures and protocols necessary to conduct sampling and geotechnical characterization activities on import borrow and other externally sourced materials that will be used in backfill, cover soil, or engineered caps for upcoming BPSOU remediation activities described in the BPSOU Consent Decree (CD) (referred to as BPSOU CD; EPA, 2020a) Further Remedial Elements Scope of Work (FRESOW) (Attachment C of Appendix D to the BPSOU CD), the 2020 Residential Metals Abatement Program (RMAP) Unilateral Administrative Order (UAO) Amendment (EPA, 2020a), and ongoing maintenance activities completed to address Butte Reclamation Evaluation System (BRES) evaluation deficiencies. This QAPP will not be used to characterize materials excavated from a source area to be ‘reused’ in the same area. Reuse of on-site source area material will be addressed under site-specific remedial action design documents and is explicitly omitted from this document.
