Climate Adaption and Mitigation - Planning or Assessment

Selected Strategy(ies)	Explanatory Text
Evaluate Reuse options that are climate conscious	Discussion of observed and forecasted climate change conditions and the associated site-specific risk are part of any reuse considerations. Both current and forecasted climate changes may impact the effectiveness of a remedial alternative."
Identify potential risk factors and infrastructure or utility vulnerabilities	Identify potential risk factors and vulnerabilities resulting directly from the impacts of climate change." Possible risk factors and vulnerabilities may include proximity to the ocean, infrastructure vulnerabilities, property affected by a revised FEMA flood plain map, vulnerability related to changes in frequency and intensity of precipitation events, vulnerability of soil type due to moisture and hydraulic changes, and ground and surface drinking water vulnerabilities."

Climate Adaption and Mitigation - Demolition or Cleanup

Selected Strategy(ies)	Explanatory Text
Reduce waste and manage materials sustainably	Practices to reduce water and manage materials sustainably may include minimizing consumption of virgin materials; minimizing waste generation; use of recycled products and local materials; beneficially reusing waste materials (e.g. concrete made with coal combustion products replacing a portion of cement); and segregating and reusing or recycling materials, products, and infrastructure (e.g. soil, construction and demolition debris, buildings)."
Sustainable land management practices	Sustainable land management practices capitalize on a "whole-site" approach that accelerates cleanup while returning a site to its natural conditions. Practices focus on opportunities to preserve natural land features, maintain open space, sequester carbon, enhance biodiversity, increase wildlife habitat, and minimize surface and subsurface disturbance. Sustainable land management practices at a brownfields site may include minimizing unnecessary soil and habitat disturbance or destruction; use of native species to support habitat; and onsite remediation approaches such as bioremediation and/or phytoremediation."

Property Highlights

The property includes the eastern portion of the former Bear River Saw Mill Site. The former Bear River Saw Mill Site was previously assessed under a Voluntary Cleanup Agreement, and environmental investigation and remediation activities have been performed at the Bear River Saw Mill Site since 1988. Remediation activities have included removal of concrete and soil impacted by PCP and preparation of a Removal Action Work Plan (RAW) for remediation of waste, predominately mine waste rock, from historical mining activities. Previous assessments of the subject property identified elevated concentrations of arsenic in areas associated with historical lode (underground hardrock) gold mining claims, primarily in areas containing mine waste rock piles. The City of Grass Valley used USEPA funding associated with the 2017 Gold Country Coalition Assessment Grant to prepare a "Remedial Design and Implementation Plan for the Bear River Mill Site East (Site Code 102417)" (NV5, December 7, 2021), which was approved by the DTSC on December 16, 2021.

Former Use: The property is currently undeveloped and vacant. Various trails and fire roads traverse the property. The property includes the eastern portion of the former Bear River Saw Mill Site, and the historically significant Galena, Bullion and Alaska Hardrock (Quartz Lode) Gold Mines. Portions of the Bear River Saw Mill Site were previously used for processing and storage of hard rock gold mining materials from the 1850s to the 1930s and for lumber milling from approximately 1956 to 1978. Historical mining maps and mineral survey plats depict the historical lode (underground hardrock) gold mining claims on the property, as well as the underground workings, which are to be physically closed as part of the proposed site development along with encapsulation of the mine waste under engineering controls and land use covenant.
