The Houston Chronicle is reporting that BP, ConocoPhillips and Shell Oil Co., have proposed language for climate change legislation that would prohibit federal regulation of hydraulic fracturing, which is currently regulated by the states. Among other things, "[t]he document recommends that states adopt standards for disclosing the contents of hydraulic fracturing chemicals 'to health professionals or state agencies' in order to protect health or environmental safety but maintain 'the confidentiality of trade secret information' in the fluids."
