They claim full disclosure of fracking chemicals will discourage innovation.
From post 14:
Every hydro-fracturing operation has MSDS sheets of all the chemicals used. Just because the list of ingredients are not run in the local paper doesn't mean they are top secret.
If disclosure were a real concern, fracking companies would not want the lists posted at all, I can just drive up to the wellsite and view the list as it stands now.
The companies are trying to avoid stupid, pointless and burdensome federal regulations - you know, the kind of stuff Freepers normally fight.
This is a state issue.
