Oyu Tolgoi Mining and Processing EIA

Oyu Tolgoi ProjectMining and Processing EIAground and underground water resources, soil, flora and fauna, living condition of human inhabitantsor native herder families of the area, socio-economic conditions, historical and cultural heritagespreserved in the area, provided that the proposed copper-gold mine and associated process facilitiesare developed at Oyu Tolgoi; and (ii) the optimal methods to mitigate the negative impacts thereof. Inorder for these objectives, Eco Trade XXK has performed the following studies since 2002:1. Environmental Baseline Study for the Oyu Tolgoi mining lease and the surrounding areas. Thestudy was performed by an independent study team in 2002 in the following areas:geographical and geological settings, ground and underground water resources, climate, airquality, soil, flora and fauna, population, socio-economic conditions, livestock and usage ofpastureland. The findings of the studies were incorporated in this assessment.2. Detailed study on the damage and degradation of ground and underground water, air quality,soil and vegetation cover of the Oyu Tolgoi mining lease; and determination of rare and veryrare plant species, their distribution and possibility to relocate, soil rehabilitation, rate of dustemission and methods to mitigate dust and dust sources. The findings of the studies are usedin this assessment.3. Summer and winter camps of the herder families who live near the project, potable andhousehold water sources and their quality, current socio-economic condition of the herderfamilies.4. Determination of the extent of impact from Oyu Tolgoi Project on the landscape, air quality,ground and underground water sources, soil and vegetation cover and socio-economic aspectsof the local residents within the project area and the surrounding areas; indicate the impactsmitigation methods. In addition, review of applicable Mongolian and international laws,regulations, standards and procedures were also done.These studies were conducted by research teams led by Sc.D. (Geography) D. Dorjsuren, Director ofEco Trade XXK, Sc.D. (biology) and Prof. A. Bold, Member of the Academy of Sciences, Sc.D.(Geology and Minerals) and Prof. N. Batsukh, Ph.D. (History) and Prof. D. Tseveendorj, Sc.D.(Physics and Math) and Prof. R. Mijiddorj, Sc.D. (Geology and Minerals) R. Battumur, Sc.D.(Economy), Т. Narantuya and T. Enkhtulga, botanist J. Sanjid, pedologist Т. Munkhbat, geotechnicianYa. Jambaljav, geographer and IT specialist P. Janchivdorj and geographer А. Tsend-Ayush. About 60researchers and specialists, The Central Laboratory of Environmental Studies, Institute of Chemistry atthe Academy of Sciences, chemistry laboratories of the Geo-ecological Institute, and the researchlaboratories of the University of Science and Technology were involved in the assessment studies. Thefindings of the studies were processed and incorporated into the final report.Prepared by ECO-TRADE LLC.,Environmental Consultants, MongoliaClient: Ivanhoe Mines Mongolia Inc(IMMI) XXKExecutive summary of OT EIA Report.
