(Beaver Shaft, La Sal, Pandora, and Snowball Mines)
The La Sal Mines Complex is made up of the Pandora Mine and 3 mines known as the La Sal Complex (La Sal, Snowball, and the Beaver Shaft).

Uranium Watch Comments on Scope of EA for Expansion of the
La Sal Mines Complex
On January 31, 2011, Uranium Watch and Living Rivers, Canyonlands Watershed Council, Grand Canyon Trust, Center for Biological Diversity, and the Glen Canyon Group of the Sierra Club submtted extensive comments to the Bureau of Land Management on the scope of the Environmental Assessment for the expansion of the La Sal Mines Complex. Among other things Uranium Watch et al. asked that the BLM develop a full Environmental Impact Statement (EIS) for the expansion of the mining operations.

Environmental Assessment of Expansion of the
Pandora, Beaver Shaft, La Sal, and Snowball Mines
In November 2010 Denison submitted a the final version of the Plan of Operations Amendment (POA) for the La Sal Mines Complex to the Utah Division of Oil, Gas and Mining, Bureau of Land Management (BLM), and US National Forest Service-Manti-La Sal National Forest. The BLM and Forest Service are in the process of developing an Environmental Assessment (EA). The draft EA, not expected until early 2012, will be available for public comment.
The Agencies held two EA scoping meetings and provided an opportunity for submittal of written comments, which were due on January 31, 2011. The EA will primarily address the portions of the La Sal MInes Complex that are on BLM or Forest Service Land: La Sal, Pandora, and Snowball Mines and the Beaver Shaft waste rock pile and radon vents on BLM land.
Denison has hired and will pay a consultant — CDM Inc. — to prepare the EA, under the direction of the BLM and Forest Service. CDM Inc. is the same consultant that Denison hired to develop their amendment to the Plan of Operations for the La Sal Mines Complex.

DIVISION OF AIR QUALITY
On May 22, 2008, Denison Mines submitted a Notice of Intent of Construct the Proposed La Sal Mines Project to the Division of Air Quality (DAW). The project includes the Pandora Mine and the La Sal, Snow Ball, and Beaver Shaft. Denison only plans to use the Beaver Shaft and Pandora access shafts.
The Utah Division of Air Quality (DAQ) accepted comments on their Intent to Approve Denison Mines Corporation's request for an Approval Order for their uranium mines in La Sal, San Juan County, Utah. The DAQ action is in response to the May 2008 Notice of Intent to Construct the Proposed La Sal Mines Project (as supplemented).

NOTICE OF INTENT TO MODIFY THE LA SAL MINES PROJECT APPROVAL ORDER
In October 2010, Denison submitted a Notice of Intent to Modify the La Sal Mines Project Approval Order to the Utah Division of Air Quality (DAQ). The request incorporates the La Sal Mine (one of the four mines that are part of the La Sal Mines Complex) into the La Sal Mines Complex mining operation. However, Denison has already commenced operation of the La Sal Mine. Denison is removing ore from the mine and disposing of waste rock on one or more of the La Sal Mine waste rock piles.
The DAQ is in the process of reviewing the NOI to Modify.
