Re: Whirlwind Mine, File No. M-2007-044, Additional Adequacy Review of a 112 DMO
application.
Dear Mr. Filas:
The Division of Reclamation, Mining and Safety (DBMS) has reviewed Energy Fuel's responses to the
original DBMS Adequacy Review of November 5th, 2007. The review is being conducted by the
Division's geochemist, engineers, hydrology specialist and environmental protection specialists. The
additional review has brought up the following issues that need additional clarifications, correction or
responses. As a matter of expedience the review memos forwarded to myself as Lead Specialist are
attached so that Energy Fuels may respond to them directly.
From the review it is apparent that there are some issues, particularly with groundwater characterization,
that will need further information and study as conditions allow. However, staff understands the dynamics
of the situation and some information may not be readily obtained until encountered or as historic mining
areas are accessed. Staff feels that gaining certain commitments from Energy Fuels for continued
hydrological characterizations within the permit is a better alternative then stipulations attached to any
approvals granted in issuance. Please respond as soon as possible to the issues noted in the attached
memos.
Staff is requesting that Energy Fuels agree to the following commitments as part of the Mine and
Reclamation Plans.
1) Energy Fuels will submit a quarterly hydrological report to the Division regarding underground
ground water conditions. The report should include location and nature of the water encountered
such as mine pools, draining drill holes or airshafts, or inflows from natural locations. Quantity
outputs should be noted as well as any remedial actions taken such as sealing, etc.
2) Energy Fuels will place tracer or dye pacts in mine pools that collect perennial flows to monitor for
impacts to surface waters. Visual inspections of the DP and PR springs shall be done quarterly for
the first 5 quarters. Once that bench mark is achieved, DBMS and Energy Fuels shall review the
data to determine if sampling intervals can altered.
