2. 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. 4 Stack 100 m A Y 14 2000 m Profile view Stack 2002 m Plan view
