This is how oil pipeline owners get away with leaking millions of petroleum products all over our natural landscape. They legislated to be able to keep using their 60 year old pipeline leak detection methods, which are a false alarm hell, despite better methods existing and being cheaper to maintain. Hire a guy whos job is to stand around and press a button if things go wrong, give them 99 false signals out of 100, then fire anybody who presses the button too often. And pretty soon, nobody ever sounds the alarm when bad shit happens, because ignoring the problem and letting people die is more profitable.
