Actually, it's thoroughly impossible to tell how the new standards work based upon by the linked articles, but it sounds like in plain language that Florida is using a computer model that could allow more flexibility in discharge permitting. This can lead to better results, whether your definition of better is "more rationally defensible" or "more in line with what my donors want." Determining which way it is better requires review by a competent expert. It might be both.
The real issue here is this phrase from TFA: "one of a kind." That's not so good.
It's important in managing environmental data to do things in the usual way. This is contrary to the way public thinks about new technologies. If there's a new iPhone, you expect it to be better in every way or at least as good. It's not like that with scientific methods; new techniques are proposed because they have certain advantages, obviously. But they always have one big disadvantage: their results are hard to compare with what you already know. You need to do a lot of work to justify doing things a new way, otherwise you can find yourself unable to compare what is happening now to what was happening before.
Fortunately Florida can't do this on its own; it has to get EPA approval. Since this is an administration that is generally favorable to environmental regulation, if they can get this past Obama's EPA that will help give these new methods more credibility.
