14.0 Construction Schedule <br />The Environmental Protection Plan (EPP), and related Environmental <br />Protection Facilities (EPF), includes three systems, specifically 1) the <br />Stormwater Management Plan (SWMP), 2) a groundwater monitoring well <br />network, and 3) the installation of impervious liners under ore pads at each of <br />the mine sites prior to reactivation of mining operations. <br />Denison has an approved SWMP and is currently implementing ongoing site <br />inspections, records documentation, and reporting programs under the <br />SWMP. SWMP inspections have also been conducted by the Colorado <br />Department of Public Health and Environment, and Denison has responded <br />promptly to any requests for additional information. <br />Included in Section 11 of this EPP are the proposed locations and construction <br />details for groundwater monitoring and compliance wells for the Sunday <br />Complex. Denison commits to install these wells as soon as the designs and <br />plans are approved (including BLM approval), dependent on site accessibility <br />during spring weather. In any case, these EPF groundwater monitoring wells <br />will be installed during 2012 so that background sampling can commence as <br />soon as practical. <br />All mines in the Sunday Complex are currently on Temporary Cessation <br />status. No ore stockpiles are present on any of the sites, so no uncontrolled <br />runoff and related discharge of potentially radioactive solids is occurring. <br />Prior to reactivating any of these mines, Denison must notify DRMS of the <br />intentions to resume operations. In conjunction with submitting formal <br />notification of the intentions to resume mining operations at a mine site, <br />Denison will provide a detailed schedule for installation of the ore pad liner at <br />that site. The schedule for reactivation of a given mine will provide at least 90 <br />days notification prior to the start of liner installation work. Denison will <br />coordinate directly with DRMS to schedule pre- construction site inspections as <br />well as post- construction inspections and approvals, if required. Upon <br />completion of installation of each of the ore pad liners, Denison will provide <br />DRMS with certification by a Registered Professional Engineer, or other <br />appropriately qualified person, affirming that the facilities have been <br />constructed in accordance with the approved designs. Denison agrees and <br />accepts that no ore will be placed on the surface at any of the reactivated <br />Sunday Mines sites until such time as the ore pad liner at each of the <br />reactivated sites have been installed and the construction thereof approved by <br />DRMS. <br />C \Users\cwoodward1Desktop \Sundays \FINAL - Environmental Protection Plan Sunday Mines Revised January 2012 docx <br />14 -1 <br />
