+ | The NMVOC and PAH emissions that result from bitumen blowing are calculated with an emission factor derived from the uncontrolled standard emission factor of the GB 2019 taking account of the maximum permitted levels and reduction-measures requirements specified in the Technical Instructions on Air Quality Control (TA Luft). The emission factors for Cd, Cr and Ni were taken from real measurements with an increased safety factor (maximum or ten-fold). | ||
+ | All emission factors remain constant for all years in question. | ||
