The aim of this project is to reduce the nutrient inputs from Belarus to the Baltic Sea in the context of the Northern Dimension Environmental Partnership, with particular consideration given to such key sectors and areas as agriculture, municipal waste water, industry, and the production and use of detergents containing phosphorus. So far, the terms of reference for an assessment and identification study have been developed by the Central Research Institute for Complex Use of Water Resources, the Ministry of the Environment, Finland, the European Bank for Reconstruction and Development (EBRD) and HELCOM, and agreed with the Belarusian Ministries of Natural Resources and Environmental Protection and the Ministry of Housing and Communal Services. Achievements: The project team has selected a priority list based on the potential to reduce discharges of nutrients into the Baltic Sea. The list has identified the wastewater treatment plants in the Belarusian cities of Polymir, Kobrin, Lida, Smorgon, Novogrudok, Skidel, Schuchin, Oshmyany, Pruzany and Lyakhovichy as well as a poultry farm in Skidelskaya.The needed investments were broken down into two categories:• investments needed to fulfil the HELCOM recommendations; and• affordable low-cost, high-efficiency investments.From this background, the needed investments at municipal wastewater treatment plants wereidentified with the following results:• Investments needed to fulfil HELCOM recommendations: EUR 60.9 million.• Priority investments: EUR 17.7 million.The total environmental load reductions resulting from the implementation of the selected priority investment projects at municipal wastewater treatment plants are as follows:• Total nitrogen load will be reduced by 166 tonnes/year.• Total phosphorus load will be reduced by 176.0 tonnes/year.And when fulfilling HELCOM recommendations:• Total nitrogen load will be reduced by 367 tonnes/year.• Total phosphorus load will be reduced by 176 tonnes/year.
