Leaders in safe, cost-efficient plans.Denison Environmental Services (DES) is a contracting group based, in Elliot Lake, specializing in all aspects of mine closure and decommissioning Decommissioning is a general term for a formal process to remove something from operational status. Some specific instances include:
Elements of the project included: hazardous material abatement, disposal of assets, construction of till core dams, demolition, shaft capping, tailings, relocation and site landscaping. In 1997, the key people involved in the decommissioning of these properties formed the DES team. Decommissioning at Denison started in 1992 and was completed in 1998. During the operating life of the mine, and beyond; throughout the decommissioning and closure periods,, Denison's employees, now represented by DES, have performed the treatment. and monitoring functions for these sites under the regulations of both federal and provincial agencies. While their work at their own facilities has been a mater of pride for years, they are now seeking to expand services available to other mining firms to encompass the full, range of decommissioning activities including long-term care and maintenance. To this end, they recently bid and were awarded the long-term care and maintenance of Rio Algom's five treat ment facilities including all sampling and reporting. This project validates their approach in answering the client's needs with practical economical solutions that are proven work. They have become a leading force in the safe and efficient implementation of closure plans. DES has an excellent safety record. Their health and safety training programs include NORCAT NORCAT Northern Centre for Advanced Technology Inc. (mineral mining R&D organization) , First Aid, WHMIS WHMIS Workplace Hazardous Materials Information System and Asbestos training for each' of their employees. To maintain excellence in mine decommissioning, the company became ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. 9001:2000 registered in spring 2001. Knowledge of mine hazards, environmental issues, current regulatory standards and contract administration gives them a unique perspective on the best programs available for your project. In their brief history they have completed projects for the following clients: Algoma Steel Inc. (ASI ASI, n See Anxiety Sensitivity Index. ) Algoma Ore Division in Wawa, Ontario. DES managed the entire decommissioning project from start to finish using their own forces for overall project management, asset removal, demolition and earthworks earthworks: see land art. .

This may be a natural process produced by plant colonization and succession, or an artificial (manmade), accelerated process designed to repair damage to a landscape due to wildfire, mining, flood, . They also perform an annual inspection of the fence and monitor the progress of mine flooding for ASI. Echo Bay Mines Limited The Echo Bay Mines Limited company was organized in 1964 to develop a silver deposit at Great Bear Lake, Northwest Territories, which became known as the Echo Bay Mine.

Ontario MNDM (Abandoned Mine Information System-Site Assessments) Timmins District. DES inspected over 300 abandoned mines in the Timmins District of, Northern Ontario to provide detailed site assessments that include GPS data of the site, detailed descriptions-and estimated costs to rehabilitate, Denison Mines Limited (Denison and Stanrock Mine Elliot Lake, Ontario Elliot Lake (2006 population 11,549) is a city in northeastern Ontario, Canada, north of Lake Huron in the Algoma District, midway between the cities of Sudbury and Sault Ste. Marie. . DES performs all long-term monitoring at both sites. The work involves: air, water and ground water sample' collection, treatment plant operation, maintenance of site and regulatory reporting. Data is managed using state-of -the-art environmental data management system Envista Billiton Base Metals (formerly Rio Algom Limited). DES in alliance with Lakefield Research and SENES consultants was awarded a five-year monitoring contract JES (Job Entry Subsystem) Software that provides batch communications for IBM's MVS operating system. It accepts data from remote batch terminals, executes them on a priority basis and transmits the results back to the terminals. The JES counterpart in VM is RSCS. is maintaining and operating effluent treatment plants, undertakes environmental sampling and performs all compliance documentation for Rio Algom, facilities in he Elliot Lake area. SITE DECOMMISSIONING AND RELATED SERVICES Denison Environmental Services offers a wide range decommissioning services: * Acid mine drainage Acid mine drainage (AMD), or acid rock drainage (ARD), refers to the outflow of acidic water from (usually) abandoned metal mines or coal mines. However, other areas where the earth has been disturbed (e.g. (AMD (Advanced Micro Devices, Inc., Sunnyvale, CA, www.amd.com) A major manufacturer of semiconductor devices including x86-compatible CPUs, embedded processors, flash memories, programmable logic devices and networking chips. ) mitigation * Tender preparation * Valuation, marketing and resale of assets * Hazardous material abatement * Permanent capping or closure", of mine openings * Hydraulic, monitoring (relocating tailing and sludge using high pressure water cannons and slurry pumps) and dredging * De-waiting * Demolition * Site landscaping * Soil sampling * Air and water quality monitoring services during the active decommissioning and post remediation phases * Boom truck rental * Long-term environmental monitoring and treatment plant operation.
