An electric utility wants to build a new coal fired power plant in an urban setting. The regulatory agency has determined that in order for the plant to be permitted it must limit its emissions to prevent the ground level SO2 concentration from exceeding 0.01 g/m3 at the site fence line 0.5 km directly downwind from the stack. What is the maximum SO2 discharge rate (g/s) the plant can emit? Use the following: Effective stack height = 50 m, Wind speed = 1.5 m/s Stability Class C, using Martin's equation: sy = 104 · X0.894 and sz = 61 · X0.911 where the dispersion coefficient is in meters and the X distance is in km X(x,y,O,H)=[(E/pi*SySzu)] [exp[-1/2(y/Sy)^2]] [exp[-1/2(H/Sz)^2]]
