Each site proposed for temporary storage of snow must be approved by environmentalists. The first raid on the territory of future authorized snow ranges was carried out today by inspectors of the Central Territorial Administration of the Ministry of Ecology and Natural Resources of the Republic of Tatarstan. All sites for future snow placement are evaluated by specialists from the laboratory of the Ministry. Soil samples are taken from the site for a comparative analysis at the end of the winter season in order to prevent reagent contamination of the land.
