Well, the EPA has done it again. On Friday they adopted a series of changes that challenge the legitimacy of the Clean Air Act, by easing restrictions on companies that continue to use old-as-hell equipment that was grandfathered in under older environmental standards. The new rules let facilities continue to use and repair old equipment without being subject to newer regulations. In other words, as long as the companies can justify that their facilities haven't "been upgraded," they can continue to pollute at older, greater levels. How does this provide a company incentive to clean up its act? It doesn't. Boston Globe has full story here.
