What are you talking about? That article didn't say the pumped slurry directly into a stream. Precautions are taken and when they fail there are procedures for fixing the situation and cleaning it up. There are spills at chemical companies across the country.
Yes, the EPA has made plenty of great regulations that help protect us and nature, but my point is that there is a broad spectrum of where to draw the line. Balancing regulations and business is tricky, and most laws are unnecessarily complex and stuffed with extras outside of the core intent.
I highly doubt this regulation is as simple as the article makes it out to be. If it was it would only consist of a few sentences. Can any of us honestly sit here and judge the validity of this regulation without knowing everything in it?
