Abstract | Dalur company produces uranium by underground leaching using sulfuric acid, and possesses both production and processing facilities. As is known, with underground leaching, pollution is reduced to an impact exerted on the ground surface and on an aquiferous stratum by the health- and nature-hazardous chemically active substances that are in use or originate in the course of uranium recovery from underground. Aiming at minimization of the environmental impact, the company pays much attention to ecological safety of the production by implementation of a dedicated ecological policy. In accordance with the ecological policy, the company carries out continuous environmental monitoring, predicts probable ecological hazards induced by the production and, based on the prediction, develops and executes various mitigation measures. Since 2012 the quality management system and the ecology management system have been functioning at the company. The certificates on conformity of the production with the international standards ISO 9001:2008 and ISO 14001:2004 are obtained. For the further advance, the Improvement Program and the Quality and Ecology Standard Fruition Program are annually developed, implemented and reported at a quarter basis, and inside and outside auditing is performed. Dalur company maintains close cooperation with governmental and regional authorities. The production is routinely inspected by state supervision agencies. The company carries out reporting on a regular basis to the Kurgan Region Department of the Federal Service for Supervision of Natural Resources of Russia. |
