location and sample interval in Appendix 6-5. Effective mitigative
measures will include avoidance; ameliorating reclamation techniques;
blending, dilution, and/or burial by normal overburden/interburden
handling and where necessary, selective handling. These mitigative
measures, listed in Appendix 6-5, are discussed in more detail in Tab
21, Minesoil Reconstruction.
Conclusions. The following conclusions are evident from the overburden
assessment at Nucla Mine:
1. Overburden and interburden information from the Phase I Nucla Mine
OIU sampling area was evaluated and statistically summarized to
define site specific conditions and to select and justify a
chemical and physical parameter list for Mire Areas 2 and 3.
2. There is little lateral variability in the local depositional
environment at Nucla Mine based upon lithologic descriptions ,
textural analyses and standard deviation values within the
individual Phase I and Phase II sampling areas.
3. Based upon local variability and relevant research, four sample
holes (one core and three chip sample holes) in Mine Areas 2 and 3
873E, 874E, 875E and 876E were drilled and sampled to accurately
predict overburden and interburden characteristics.
4. A noncontaminating lithium based drill stem joint lubricant was
used at all 1986 sample sites. Air was the only drilling medium
utilized.
5. Based upon site specific conditions and CMLRD stipulations , the
overburden and interburden parameter list for Mine Areas 2 and 3
included pH, electrical conductivity, acid base potential
(including associated analyses) , saturation percentage, iron and
manganese for all samples. Nickel , molybdenum and zinc analyses
were also included for samples collected from site 873E.
