EPA Announces Advance Notice of Proposed Rulemaking Regarding Hydraulic Fracturing Chemicals and Mixtures under TSCA
EPA has taken another step toward additional regulation of hydraulic fracturing chemicals and mixtures. In August 2011, Earthjustice and 114 other groups filed a petition asking EPA to promulgate rules under Sections 4 and 8 of the Toxic Substances Control Act (TSCA) that would force companies to perform toxicity testing, provide mandatory chemical identification and disclosure, and submit health and safety studies on chemicals used in hydraulic fracturing and related oil and gas production activities. In response to the Petition, EPA declined some aspects of the requests, but chose to move forward with regard to additional disclosure of hydraulic fracturing chemical substances and mixtures, and the best way to obtain this information.
