The viewpoint I have heard is that most enterprises want to fix the leaks if they are informed about where they are to a high degree of specificity (e.g., ~20 meters). Then they can send a crew with detection equipment. They're trying the carrot rather than the stick for now. Anecdotally, this has worked. It's not clear, to me at least, that there should be criminal penalties for medium sized leaks like in TFA. I don't know at all what the regulations are.
