In this work, an economic assessment of environmental damage to water and land resources is calculated, and the cost of a project for the reclamation of destroyed lands within the territory of the Komsomolsk gold recovery plant is determined. The object of the study is directly the territory of the enterprise, which is located in the Tisulsky municipal district of the Kemerovo region. According to our calculations, the total assessment of environmental damage from the plant's activities amounted to 458 million rubles, of which: 294 million rubles - accumulated environmental damage from water pollution; 164 million rubles - accumulated environmental damage from soil pollution in the surrounding area. The cost estimate of the destroyed land reclamation project amounted to 716.7 million rubles.
