"Oil and gas companies that are using hydraulic fracturing -- or fracking -- off the Southern California coast must report chemicals discharged into the ocean under new requirements released Thursday by federal environmental regulators."

"The U.S. Environmental Protection Agency (EPA) published the requirement in the federal register. It becomes effective March 1.

Environmentalists hope the change will allow the public a better view of chemicals used in both onshore and offshore fracking. Calif. Gov. Jerry Brown signed a law requiring companies that frack on land in California to disclose what chemicals they use. Companies that participate in fracking in other states often don’t have to disclose the chemicals they use."
