Procedure for calculation of technological values of emissions with a purpose of developing for an integrated environmental permit

System of technological regulations of negative impact on the environment based on best available techniques could be perspective environment regulation. The hygienic regulation of environment is based on the principle of non-exceedance of outdoor (ambient) air pollution level at control points. The level is represented by maximum allowable concentrations. The implementation of technological standards into the environment regulation has changed its essence. Technological standards are standards for emissions and discharges of pollutants, as well as standards for permissible physical impacts, which are established using technological values.The assessment of air pollution and comparing the results with technological values seems possible after implementation of technological standards into the environment regulation. The main focus of the study is to determine the procedure of calculating the technological values of emissions. It was considered on the example of an inorganic chemical industry enterprise in the Perm region. A number of environmental documentation developed for the enterprise was analyzed, the methodology for selecting information and technical reference documents was described during the study to calculate the technological values of emissions. Procedure calculating the technological values of pollutant emissions was developed during the study. It is universal and applicable to enterprises in any sectors of industry.
