Do you believe the EPA should not be able to restrict the high-pressure injection of toxic chemicals into the aquifer because the information isn't "public"?
We agree on many things, but this isn't one of them.
The EPA clearly (at least at present) has jurisdiction over polluted groundwater. That's the kind of thing it was created for.
Industry is not "allowed" to pollute groundwater just because its use of the pollutant is a "trade secret". That's not how it works. This is about the basis of regulations. If the public and "reasonably reproducible" science says (thin air example) isofurans above 20ppb are harmful to health, they can be regulated.
That means they could not be released into groundwater, "trade secret" or not. (Not that I am any fan of EPA... I have had far too much experience with it to think it is our friend.)
Look, I'm a big fan of Edward Snowden and Chelsea Manning too, but when you have corporations with vested interests in keeping information away from the public, forcing the government to only be able to act on information that's public will only let them run further amok.
That's really not how it is written. I suggest you read the actual bill.
