On May 31, 2016, EPA Region 6 issued an Administrative Order (AO) for Plan Implementation (AO Plan Implementation) to the City of Opdyke West (Respondent). City of Opdyke West has requested additional time to complete the construction schedule. The AO incorporates the new construction schedule and the deadline extension request submitted by Respondent in their compliance plan. On July 19, 2011, EPA Region 6 issued the original AO under its authority pursuant to the Safe Drinking Water Act to Respondent for violations at its water system in Levelland. The Original AO was issued in response to violations of the arsenic 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 arsenic; 2) a cost analysis of the proposed plan; and 3) a construction schedule. This AO extends the compliance deadline to February 1, 2017 and supersedes the AO issued on July 19, 2011.
