Site Reclamation Activity
April 2000 - March 2001
Page 9
Other surface and groundwater sample results in the Mayflower
Mill area (Pond No.3 stream SCTP31 and SCTP32 and Wells EOMW1
and EOMW2) were at or below levels of metals observed in the
past.
2) American Tunnel area
Cement Creek monitoring reflects some improvement due to
stream treatment. Seeps entering the stream bed between CC1
and CC2 carry enough metals that CC2 quality is not the same
as treated effluent from the American Tunnel treatment system
even though basically all of the stream flow has been treated
from August through the end of April, since 1996 (except for
June 1999 g November 1999 when treatment was temporarily
suspended).
The seep ATS2, originally from the toe of the American Tunnel
waste dump, has maintained the level of improvement first seen
after completion of the waste dump reclamation. The seep ATS1
appears to have disappeared or relocated due to the
reclamation of the waste dump.
3) Terry Tunnel /Lake Emma
Eureka Creek monitoring above the Terry Tunnel continues to
show the same level of improvement, as compared to previous
years.
4) Mine Pool
The Terry Tunnel and American Tunnel bulkhead mine pool water
quality samples submitted with this report reflect the quality
of water behind the bulkheads.
MONITORING - Settling, phreatic water levels and bulkhead
inspections
Included in Appendix A are settlement monitoring data for Tailings
Pond No.4, phreatic water level monitoring for Tailings Pond No.4
and American tunnel pressure gage readings indicating depth of mine
pool.
Tailings Pond No.4 settling and phreatic level monitoring does not
reveal any adverse trends. The phreatic level remained low since
pond reduction occurred.
Monitoring of the bulkhead pressure gage in the American Tunnel was
performed more often than required by TR -14. As of March 30, 2000,
the pressure was 438 psi which reflects a pool surface elevation of
11,661 feet MSL. With some annual variation, this level reflects
mine pool physical equilibrium. During each monitoring visit, the
tunnel and bulkhead are inspected for changes. No changes have been
noted to -date.
