Answer 1

Industrial chimneys like the ones on powerhouses must be a certain height depending on emissions. It depends on what kind of plant and where it is. Different states have different guidelines and there are federal guidelines for some things. Remember most of the things coming out of smokestacks are very bad for humans that is why they are released usually over 300 ft up so it can mix with the wind.
