II. SITE CHARACTERISTICS

A. Facility Description: Entire watershed below Carson City and below Virginia City, extending approximately 130 miles to the East, at the River's terminus in the Carson Sink.

B. Status: Active Inactive -~X"'---- Unknown ___ _

C. History (Include accidents or injuries on-site, complaints from public, previous releases and agency reports):

SEMS-RM DOCID # 100011071

EPA-lead investigation since the early 90's, when most of the data gathering occurred. In 1995, the source area investigations focused near the historic mill sites in the Carson City, Mound House, Virginia City, Silver City and Dayton communities, culminated in the OUl (Soils) ROD and remedial work. Four yards, some with free product, were remediated by excavation and/or capping. No known accidents occurred during fieldwork. Since the 90's, EPA has worked closely with NDEP, USGS, and UNR, as well as our own consultants, to investigate the nature and extent of mercury contamination in the OU2 (active river channel, sediments and banks) area. Data has been collected from throughout the approximately 130-mile stretch of river from Carson City to the Stillwater Wildlife Refuge. The sample media has included sediments, bank material, water samples (Hg total and MeHg), fish, waterfowl, and other potentially impacted biota. No known accidents have been noted.

October 2015 fieldwork- RPM led team of agency, NDEP and FSPT staff to the OU2 area (delta, Lahontan Reservoir, spillway, Sheckler Reservoir, the FSPT reservation and the Old River), collecting 11 core samples up to 72" deep using the R9 Lab's Vibracore,

D. Is personal protective equipment required by Facility/Site Management? List equipment and specific areas where required: Level D, unless product is observed in general. Additionally, core samples may require starting with Level C (APR), tyvec and gloves, with active vapor monitoring (Ohio Lumex) - see Section III A for soil sampling and processing JHAs.

E. Are employees working at the facility/site monitored for exposure to airborne contaminants? If so, describe: Ohio Lumex.
