On November 23, the Environmental Protection Agency announced it will solicit public input on hydraulic fracturing chemical disclosure rules, in response to a petition submitted August 4 by Earthjustice, the Sierra Club, and American Rivers asking the agency to require public disclosure of the chemicals and their potential risks to human health and the environment. This decision follows a November 2 interim response to the petition from EPA that did not grant the environmental coalition’s request that all exploration and production chemicals be identified and tested for toxicity.
