Re: Sunday Mine, Permit M-1977-285, Environmental Protection Plan, Clarification of Due Date
for Submittal, and DMO Permit Amendment.
Dear Ms. Woodward,
In response to your recent letter indicating confusion over the due date for the submittal of the
Environmental Protection Plan (EPP) that Denison is preparing for the above-named permit, the
Division would like to provide clarification of the timeframe and the subsequent permit amendment
requirement.
On February 8, 2008, Denison received the formal notice of determination of designated mining
operation (DMO) status from the Division. Due to the complexity and anticipated time necessary for
concurrently preparing an EPP for this permit and five others, Denison requested that the due date be
set for 365 days after receipt of the Division's notice. The extended timeframe was approved, and the
due date for the EPP was set for February 7, 2009. -
On June 6, 2008, the Division sent a letter to Denison, that described the implementation of new
legislation (BB 1161) which changed the definition of a designated mining operation (DMO), and
stated that all uranium operations, including the Sunday Mine, were now defined as DMOs. The DMO
requirements cited in that letter may have been misinterpreted to have reset the 365-day timeframe for
submittal of the EPP, to be based on the receipt of this second notice.
The Division agrees that Denison has demonstrated steady progress in the data collection, report
preparation and submittal of several of the important portions of the EPP. The Division recognizes
that the final EPP is not ready for submittal, and additional time is needed for EPP completion and
submittal as an amendment to Permit M-1977-285. The Division also acknowledges the potential for
confusion regarding the due date for submittal. Therefore, the Division is extending the EPP due date
and clarifying the deadline for amendment of the application.
Pursuant to HB-1161, Denison Mines must submit a completed EPP and all materials necessary to
amend the existing 112 permit to a 112d-2 permit by June 8 2009.
