Site Characteristics

General Site Description: (5/2/03 MLC/SAS) The mine site consisted of German and Wildhog Tunnels. There was 1.1 acres of mining workings on the site which included tailing piles and waste rock. There was adit drainage from the German and Wild Hog Tunnels. The site is not secure from trespassers. There were no buildings on the property.
Site History: (5/2/03 MLC/SAS) The Vesuvius vein was discovered in 1895, and the adit driven to explore the vein was known as the German Tunnel. A five-stamp mill was moved in from the old Knott Mill and operated at the German Tunnel until 1902 [Taber, 1949]. During the same time period, the Stocks-Harlow vein was being mined and this location also had a five-stamp mill. In 1902, both of these properties were organized into one mining company, and a new camp was built about Ľ mile down the mountain below the German Tunnel [Taber, 1949]. Near the camp site, a new adit called the Wild Hog was driven into the hillside, and a five-stamp mill was moved to this new location. Development on the new adit was intermittent through 1923. In 1945, the workings were mostly caved in according to the mine and mineral deposit reports, with the exception of the Wild Hog adit. In 1949, more development work was completed on the Stocks-Harlow vein, but in all, the entire mine’s production was considered small [Oregon Metal Mines Handbook, 1951]. The site is currently being used for timber harvest.
Contamination Information: (5/2/03 MLC/SAS) Possible metals contamination (arsenic, copper, lead, and mercury) in waste rock and adit drainage from German and Wild Hog Tunnels.
Manner and Time of Release: (5/2/03 MLC/SAS) Impacts to the envirnoment are from past mining operations.
Hazardous Substances/Waste Types: (5/2/02 MLC/SAS) No analytical data has been collected. There maybe elevated metals in site soil, waste rock, adit discharge, surface water and sediments.
Pathways: (5/2/03 MLC/SAS) Possible impacts to Sharps Creek from the Wild Hog Tunnel drainage.
Environmental/Health Threats:
Status of Investigative or Remedial Action: (5/2/03 MLC/SAS) In August 2002, DEQ conducted a site inspection at the German and Wild Hog Tunnels.
German Tunnel: The German Tunnel is located on a small road heading north of the Bohemia Saddle. At the German Tunnel, water was discharging from the adit opening at a rate of approximately 1 gallon per minute. The adit water and the channel rock were stained yellow. DEQ measured the pH (4.06) and conductivity (605 µmhos/cm) of the adit water. Both the yellow staining and the field parameter measurements indicated the presence of AMD. A large PVC pipe funneled the AMD down the slope into a road side ditch. The drainage went under the road and drained into a meadow. There was approximately 500 feet of visible AMD. There was approximately 200 cubic yards of waste rock present on the small road and down the slope near the German Tunnel. The waste rock was partially vegetated in a few areas. In addition, a 15 to 20-foot cut in the hillside was excavated just north of the German Tunnel. According to Larry Broker the excavation had occurred in the last 3 months.
Wild Hog Tunnel: The Wild Hog Tunnel is located above Sharps Creek by the Lower Musick access road. At the Wild Hog Tunnel, clear water was discharging from the adit opening, and a slight orange staining was observed on the channel rock (See Attachment C – Site Photo Log). The adit discharge drains into Sharps Creek. DEQ measured the pH (7.55) and conductivity (167 µmhos/cm) of the adit water. The field parameter measurement results do not demonstrate AMD; however, the orange staining may indicate past AMD discharge (iron oxide). A large tailings pile was observed approximately eighty feet west of the Wild Hog Tunnel. The tailings pile measured approximately 100 feet high by 150 feet wide at the base and did not appear to be actively eroding into the creek. DEQ collected field parameters from Sharps Creek below the Wild Hog Tunnel at the Lower Musick access road. The pH reading was 6.5 and the conductivity reading 148 µmhos /cm.
Based on the completed site evaluation, the Site Assessment Program recommends an expanded preliminary assessment to evaluate metals in soil, sediment and surface water.
