Environmentalist Shawn Porter contends that the Arkansas Oil and Gas Commission rule on disclosure of chemicals used in fracking to tap gas deposits in the Fayetteville shale isn’t sufficiently transparent. (As noted here, while Arkansas has proposed requiring disclosure of specific chemicals used, it will allow companies to keep secret the formulas for mixing the chemicals in each well.)

Porter writes a call for objection to the Commission’s adoption of the rule without further public hearings.
