Jun 14 2011 While a tall stack may reduce pollution concentrations locally it does not actually reduce total emissions which travel downwind and can hurt air quality elsewhere. At the same time stacks must be built high enough to prevent downwash which occurs when large buildings alter wind patterns and cause emissions to reach ground level more quickly.

For existing plants in rural areas coal cleaning can reduce sulfur content of the coals used by about 40 percent. Advanced coal cleaning methods may be able to increase the amount of sulfur and ash removed but all of the processes are in their early stages of development and many may be high cost for the extra sulfur removal that is accomplished.
