{"abstract":"In its response to a citizen petition submitted under section 21 of the Toxic Substances Control Act (TSCA), EPA indicated that as a first step, it would convene a stakeholder process to develop an approach to obtain information on chemical substances and mixtures used in hydraulic fracturing. To gather information to inform EPA's proposal, the Agency is issuing this advance notice of proposed rulemaking (ANPR) and initiating a public participation process to seek comment on the information that should be reported or disclosed for hydraulic fracturing chemical substances and mixtures and the mechanism for obtaining this information. This mechanism could be regulatory (under TSCA section 8(a) and/or section 8(d)), voluntary, or a combination of both and could include best management practices, third- party certification and collection, and incentives for disclosure of this information. In addition, the Agency is seeking comment on ways of minimizing reporting burdens and costs and of avoiding the duplication of state and other federal agency information collections, while at the same time maximizing data available for EPA risk characterization, external transparency, and public understanding. Also, EPA is soliciting comments on incentives and recognition programs that could be used to support the development and use of safer chemicals in hydraulic fracturing.","action":"Advance notice of proposed rulemaking.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2014/05/19/2014-11501.html","cfr_references":[{"chapter":0,"citation_url":null,"part":null,"title":40}],"citation":"79 FR 28664","comment_url":null,"comments_close_on":"2014-08-18","correction_of":null,"corrections":[],"dates":"Comments must be received on or before August 18, 2014.","disposition_notes":null,"docket_ids":["EPA-HQ-OPPT-2011-1019","FRL-9909-13"],"dockets":[{"supporting_documents":[{"title":"Documentation of EO 12866 Review; Hydraulic Fracturing Chemicals and Mixtures ANPRM (RIN 2070-AJ93)","document_id":"EPA-HQ-OPPT-2011-1019-0009"},{"title":"Ref 1: 1.
