Permit No. NI-2000-082, East 8r" Street Operation
Dar Mr. Refer:
This letter is being written to address technical issues, which must be resolved before the Division of Minerals
and Geology (DMG) can approve the new 112 application submitted by your company (File No.

storage reservoir, it is recommended that this guide be used.
2) As noted in the Office of the State Engineers (OSE), "Response to Reclamation Permit Application

ground water by evaporation, dust control, reclamation, water removed in the mined product and
processing.

type of well permit, as applicable. However, prior to obtaining a permit, an approved water supply plan or
decreed plan for augmentation is required.
Therefore, prior to exposing any ground water to evaporation, the applicant must demonstrate compliance
with OSE requirements, in order to be in compliance with rule 3.1.6. As an alternative, the applicant can
