On March 29, 2017, EPA Region 6 issued an Administrative Order (AO) for Plan Implementation (AO Plan Implementation) to the Millersview-Doole WSC(Respondent). Respondent has requested additional time with the construction schedule. The AO incorporates the new construction schedule compliance deadline extension request submitted by Respondent in their compliance plan. On November 16, 2011, EPA Region 6 issued the original AO to Respondent for violations at its water system in Millersview. The Original AO was issued in response to violations of the Radionuclides maximum contaminant level (MCL). The Original AO required Respondent to comply immediately with the referenced MCL or to submit to EPA 1) a detailed plan to meet the Radionuclides MCL; 2) a cost analysis of the proposed plan; and 3) a construction schedule. This AO extends the compliance deadline to December 17, 2018 and supersedes the AO issued on November 16, 2011.
