Denison Mines (USA) Corp. ("Denison") is please to provide this Environmental Protection Plan (EPP)
for the Denison Sunday Mines Group.
On February 8, 2008, Denison received Notices of Determination of Designation Mining Operation
(DMO) from the State of Colorado Division of Reclamation, Mining and Safety (the "Division") for the
following five Colorado Mines:
• Sunday Mine (M-1977-285)
• Carnation Mine (M-1977-416)
• St. Jude Mine (M-1978-039 HR)
• West Sunday Mine (M-1981-021)
• Topaz Mine (M-1980-055 HR)
By letters dated March 7, 2008, Denison notified the Division under Rule 7.2.3(1) of the Colorado
Mineral Rules and Regulations for Hard Rock, Metal and Designated Mining Operations, that it was not
challenging these determinations, but that it would proceed to prepare EPPs for each of these mines in
accordance with Rule 7.2.3(2). In those letters, Denison also advised the Division that it believed that in
the course of preparing such EPPs it may be able to demonstrate that some or all of the mines should be
considered to be exempt from the EPP requirements under Rule 1.1(14)(e) or Rule 7.2.6(1).
Two of these mines, the Carnation and St. Jude are currently permitted as limited impact operations (110
permits), while the remaining three, the Sunday, Topaz and West Sunday, are currently permitted as
Regular Operations (112 permits).
On February 8, 2008, Denison received the formal notice of determination of DMO status from the
Division. Due to the complexity and anticipated time necessary for concurrently preparing an EPP for the
