For this question do not use units in your answer. Background pollution is 40 ppm, pollution from source 1 is so 1=100 tons and source 1 has a transfer coefficient of a;= 0.2 ppm/ton. Pollution from source 2 is so 2=200 tons and source 2 has a transfer coefficient of a2= 0.2 ppm/ton. What is current pollution at the receptor? ppm If MC;(A1)=15A1 and MC2(A2)=6A2, and the goal is to reduce ambient pollution down to 53 ppm. How much should firm 1 abate? tons How much should firm 2 abate? tons
