Rathbun - OSM Joe Dudash -DMG Mike Neuman -TerriMatrix (office record review only) This was a Random Sample Oversight Inspection. The inspection began at the TerriMatrix office in Steamboat Springs, CO. The records for the mine are kept at this private office as there are no facilities remaining at the mine. Credentials were presented to Mr. Neuman prior to initiating the inspection. Current Status: The mine has been backfilled, graded, resoiled and seeded. Generally speaking the disturbed area is divided into the "East" side (330 acres) and the "West" side (32 acres). County Road 53 separates these two areas. The East side was seeded at different times ranging from 1979 to 1986. HGCC has supplied DMG with a map delineating the areas by year of seeding. The West side was seeded in 1987. Phase I bond release has been approved for those lands on the East side. No release as of this date on the West side. The loadout was transferred to the Seneca Mine as a separate permit in 1992. Records review: 4 ponds and 2 Small area exemptions serve the disturbed area. Ponds #1, #2, and #3 were reconstructed (spillways) and recertified on January 13, 1993. These three ponds are located on the West side. Pond 4 (HG-8), located on the East side was certified as-built on April 14, 1986. All ponds are receiving Quarterly inspections the last being accomplished 1-19-95. The two SAE's are located on the West area and are associated with topsoil stockpile areas. One of the piles (Storage Area B) has been removed while the other (Storage Area C) is still in place. Future use of this material, outside of pond rehabilitation work, is unknown. This will need to be addressed prior to Phase I bond release for the West side. 6 seeps have been identified in the reclamation area and are being monitored by H-G with results submitted to DMG on an annual basis. Seep #RSP-5 is in close proximity to a slump area in the South-East section of the East area. The seeps have a pH range of from 6.5 to 8.5 and flows of from 1 to 6 gaUmin.
