The town of Smog, Idaho is located in a river valley and has a footprint of 6 km x 2 km.  It has an average daily emission rate of 1000 kg/day of PM2.5  into the atmosphere from wood burning stoves.  The background concentration of PM2.5 is 0.5 µg/m3.  During a cold winter day in Smog, the mixing height is only 50-m and the average wind speed is 2 m/s entering perpendicular to 2 km dimension.  Assume no depositional loss for PM2.5.

a) What is the steady state concentration of PM2.5 in this air shed?  

b) Does this meet the NAAQS standard?
