Frack Loophole

Some environmental groups and state lawmakers on the front range say a proposed state rule requiring oil and gas drillers to disclose fracking chemicals will be worthless unless regluators close a trade-secrets loophole. The Denver Post says most companies are voluntarily complying now on a public data base, but the opposition says any number of chemicals could be hidden if a company says they are trade secrets.  The state oil and gas consrvation commission will take up the matter December 5th.
