On November 23, 2011 the EPA issued a letter partially granting a petition from the environmental group Earthjustice requesting disclosure and evaluation of the fluids and chemicals used in hydraulic fracturing under the Toxic Substances Control Act (TSCA).
Earthjustice had submitted the petition in August 2011 on behalf of more than 100 public health, environmental, and “good government” groups requesting that the EPA “adopt a rule under TSCA section 4 [15 USC 2603], requiring that manufacturers and processors of E&P Chemicals (defined in the petition as “chemical substances and mixtures used in oil and gas exploration or production” - ed.) conduct toxicity testing of all E&P Chemicals and identify all chemical substances and mixtures tested.” The petition also asked for the “promulgation of a rule under TSCA section 8 [15 USC 2607], requiring maintenance and submission of various records related to E&P Chemicals, calling in records of allegations of significant adverse reactions to E&P Chemicals, and requiring submission of all existing health and safety studies related to E&P Chemicals.”
Earlier in November, the EPA provided an initial response to the petition in which they denied the TSCA section 4 request, as the petition did not “set forth sufficient facts to support the assertion that it is ‘necessary to issue’ the requested TSCA section 4 rule, as required by TSCA section 21(b)(1).”
However, as stated in the November 24 letter, the EPA “has now decided to partially grant the TSCA section 8(a) and section 8(d) requests in the petition,” because they “believe there is value in initiating a proposed rulemaking process using TSCA authorities to obtain data on chemical substances and mixtures used in hydraulic fracturing.”
