The subject matter of this paper is the operation of Kotlass pulp and paper plant. The amount payable by the plant for the discharge of pollutants into the basin of the Northern Dvina River represents its substantial performance indicator. The pollutant discharge payment is minimal, if the maximal permissible discharge limit is not exceeded. Otherwise, the payment amount goes up. If the concentration of discharged pollutants may cause degradation of the water body, the amount would be by far bigger, given the cost of the water body recovery. If the quality of discharges is higher than the one declared, or if the quality of the discharges is higher than the quality of the water in the recipient water body, the enterprise is exempt from a fraction or the whole of the tax amount due and payable. The analysis of the wastewater discharged by this enterprise has proven that the major portion of the pollutant discharge payment represents the amount due and payable for excessive discharges that fall beyond the limits. The diagrams that accompany the paper constitute a clear representation of this statement. Three streams of wastewaters discharged by Kotlass pulp and paper plant are delivered into surface fishery waters. The composition of each wastewater stream and the per-pollutant payment amount is provided in the tabular form. The top five pollutants that account for 97 % of the payment amount have been identified. The major pollutants include methanol (54 % of the discharge payment) and suspended solids (21 % of the discharge payment). On the basis of the above, the principal environmental protection plan of actions was developed to assure that the maximal permissible discharge limit is not exceeded by Kotlass pulp and paper plant. The proposed plan is designated to resolve specific process-related issues from the viewpoint of economy and environmental protection. Its implementation will reduce discharges of suspended solids by 50 %, whereas the concentration of methanol in the wastewater will also go down.
