Why are some industrial chimneys so high, like what’s the difference if it’s 150 or 300 meters?

I work at a place currently undergoing expansion. A chemical we emit is dangerous to humans, but *rapidly* decomposes to something harmless when exposed to the enviroent. If our exhaust was only 1′ tall, there is a legitimate risk that downdraft could cause local exposure. If it were 10′ tall, rain might pull some of it down (even though it is decomposed quickly in water). Our exhaust is 50′ tall- eliminating any risk to humans in the area. If we worked in an area with skyscrapers or other humans living above us, we would need to go higher. But OSHA and the engineers who know more than me, the lowly chemist, have determined that this is safe.
