I have reviewed Trapper Mine Inc.'s (Permit No. C-81-010) Phase II Bond
Release Application (SL-6). Specifically, I have reviewed the
Documentation of Successful Vegetation Establishment and Topsoil
Replacement Documentation of the application.
The vegetation monitoring data clearly demonstrates that cover of the
three reclaimed areas, A,D&H Pits RSC 1987-1999, AsH Pits RSB 1995-2001
and D&F Pits RSA/B 1996-2001, meet the Phase III bond release standards
for cover and shrub density at Phase II. The cover sampling data also
shows that the mine has established a diverse mix of perennial species
across the areas. The percent ground cover and species composition
values comply with the requirements of the State's guidelines for Phase
II bond release. Based on this information the Documentation of
Successful Vegetation Establishment section of the application appears
to meet the State's requirements,
The information on topsoil replacement provides values for average
topsoil replacement depths for various parcels within the three areas.
Topsoil replacement depth values from either load count data or
replacement sampling depth data collected by State inspectors. Average
depths range form 10.6 to 22.4 inches based on load count information.
Based on this information topsoil has clearly been replaced and the
overall average would exceed the required replacement depth of 12
inches. Based on this information the Topsoil Replacement Documentation
section of the application appears to meet the State's requirements.
The application also provides a history of reclamation activities at
each parcel that includes topsoil replacement, seedbed preparation,
fertilization, and seed mixture information. This too complies with the
State's requirements.
Based on my review the application complies with the State's
requirements for topsoil replacement and vegetation establishment for
Phase II bond release.
If you have any questions please contact me.
