Krasnodar GRES Project Volume I11 Environmental Assessment

Maximum concentration of nitrogen oxides accounting for background pollution
and summation effect with sulfur dioxide fim = 0,59 of maximum permissible
concentrations shall be reached at a distance of om = 3324.1 meters.
According to the OND - 86 requirements summation effect from pollutants should
not exceed 1.0.

Table 5.6 indicates that the maximum pollutant concentration (MPC) of nitrogen
oxides calculated account for a background pollution level of 0.0114 mg/m3, and
the summation effect with sulfur dioxide, will be 0.59 shares of MPC in the area
of Perepravnaya which is below the regulatory limit of 1.0 shares.
Appendix 22 to this report (the map of Mostovskoy district) is representative of
nitrogen oxide concentration versus distance from the power plant stack curve
(accounting for background concentrations).
