The plan and profile views of a pollution source and surroundings are given below. For an emissions rate of 165.0 g/s, Class D stability, rough terrain, and a wind speed of 7 m/s (at 10 m), calculate the ground-level concentration at a receptor (A) that is 2002 m away from the source but not directly downwind (see diagrams). Assume plume rise is 50 m. 100 m Stack Stack u 2000 m Profile view U 2002 m Plan view
