Final Determination to Withdraw Perchlorate under SDWA (Final)
Jul. 21, 2020
EPA is announcing its withdrawal of the 2011 determination to regulate perchlorate in accordance with the SDWA. On 11 February 2011, the EPA published a Federal Register document in which the Agency determined that perchlorate met the SDWA's criteria for regulating a contaminant. On 26 June 2019, the EPA published a proposed national primary drinking water regulation (NPDWR) for perchlorate and requested public comments on multiple alternative actions, including the alternative of withdrawing the 2011 regulatory determination for perchlorate. The EPA has determined that perchlorate does not occur "with a frequency and at levels of public health concern" within the meaning of the SDWA. In addition, in the judgment of the EPA Administrator, regulation of perchlorate does not present a "meaningful opportunity for health risk reduction for persons served by public water systems." Accordingly, the EPA will not issue a NPDWR for perchlorate at this time. For purposes of judicial review, the regulatory determination in this document is issued as of 21 July 2020.
