Dear Mr. Campbell:
On November 18, 2005 the Division of Minerals and Geology approved the Technical Revision application submitted to
the Division on October 18, 2005, addressing the following:
Groundwater quality monitoring plan.
^Please note that the operator has proposed that in the event that the quality of groundwater at the point(s) of
compliance exceed maximum baseline levels by one standard of deviation for the parameter of interest and cause an
exceedance of a drinking water standard at a site or a specific well, [hen mitigative measures will be taken. As a point of
clarification, the"trigger" point that will be applied and enforced 63' the Division during on-going water quality
monitoring at the Lupton Lakes Resource is as follows: The Statewide groundwater standard or "MCL" if nvailable, or
the baseline (ambient) concentration for analytes where the baseline concentration exceeds the concentration of the
Statewide groundwater standard or `MCL "; or the baseline concentration for analytes (Phosphate-Total, Chlorinated
Pesticides (8081), Herbicides (8151), TEPC (8015 mod.), BTEX + MTBE (8021 mod.)) where there is no existing
Statewide groundwater standard.
The terms of the Technical Revision No. 2 approved by the Division are hereby incorporated into Permit No. M-2004-
078. All other conditions and requirements of Permit No. M-2004-078 remain in full force and effect. Also, there is no
change in the amount of financial warranty required as a result of this groundwater quality monitoring plan.
