RE: Heintzelman Project (Pit 116); DRMS File No. M-2009-018; Adequacy Review - 06
Dear Mr. Janes,
The Division of Reclamation, Mining and Safety (Division) has identified several other
comments and questions that must be addressed prior to the Division's decision due date. Please
be advised that if you are unable to satisfactorily address any concerns identified in this
review before the decision date, it will be your responsibility to request an extension of the
review period. If there are outstanding issues that have not been adequately addressed
prior to the end of the review period, and no extension has been requested, the Division will
deny this application.
6.4.7 Exhibit G - Water Information
The Division has received the water level data from the Varra Del Camino site, submitted by
CGRS on January 27, 2010. The information provided to the Division did not contain enough
data to properly characterize the local groundwater hydrology. Therefore, the Division
cannot approve the Applicant's proposed trigger point. The Division has identified the
following options in regard to satisfying this adequacy issue:
a. Commit to not exposing groundwater until five quarters of baseline elevations from
the proposed monitoring wells have been collected, to be measured on a monthly
basis. The collected data shall be submitted to the Division as a Technical Revision,
at which time the Division will review the data and establish dewatering trigger
points.
b. In lieu of collecting five quarters of baseline data, the Applicant may provide the
Division with historic groundwater data, through a Technical Revision, which
adequately characterizes the local hydrology. The Division would review the data and
establish appropriate dewatering trigger points.
c. The Applicant may also choose to obtain agreements between Varra Companies and
well owners within the defined cone of depression, stating Varra Companies is to
provide a form of compensation to the well owners in the event their wells are
