Schwartzwalder Mine
Permit: M-77-300 Anniversary Date: September 28, 1999
Dear Mr. Squire:
The Schwartzwalder Mine (Mine) is located in Jefferson County. Thc~ Mine has a
total permitted affected acreage of 57 acres in Section 25, TZS, R71 W, 6PM artd Section 8,
T3S, R70W, 6PM. The Mine does not have a phased reclamation plan, is not in temporary
cessation, and will continue operations in the next report year. There was n~~ increase in
the amount of affected acreage during the period covered by this report, and no additional
disturbances are anticipated during the next report period. There was a reduction by 2.0
acres in the affected area for Section 8, T3S, R70W during the period covered by this report.
A total of two acres of the permitted affected acreage were reclaimed during the
report period. The two acres reclaimed are located in the NE'/q, NWl/4 of Sep=lion 8, T3S,
R70W, 6PM. The reclaimed area had been used by the Cotter Corporation for ore storage
and was reclaimed at the request of the property owner prior to the cessation of all other
mining activity under M-77-300. The Division of Minerals and Geology (DMG) was notified
of, and approved, this reclamation activity under Technical Revision No. 003 to M-77-300
in May of 1996. The reclaimed area, known as the Transfer Pad, was bonded for
reclamation under the Colorado Department of Public Health and Environment (CDPHE)
radioactive materials license CO-369-03. The CDPHE released the Transfer Pad for
unrestricted public use on December 12, 1998. Approximately 3,600 cubic yards of topsoil
were placed on the Transfer Pad during January and February of 1999, and the area was
seeded for revegetation in May of 1999. The seed mixture used was based L.pon a March
25, 1997 USDA recommended mixture for the Transfer Pad area. This mixture is different
from the mixture specified in M-77-300. No soil amendments were deemed ne~=essary. Note
that all topsoil application and seeding were performed under the direction o:= the property
owner. A map depicting the reclaimed area is attached as Exhibit 1 to this report and a copy
of the USDA-recommended seed mixture and seeding rate per acre is attached as Exhibit 2.
