On December 12, 2017, EPA Region 6 issued an Administrative Order (AO) for Plan Implementation (AO Plan Implementation) to the City of Smyer (Respondent). Respondent requested additional time to complete the construction schedule. This AO incorporates the new construction schedule deadline extension request submitted by the 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 arsenic violations at its water system in Smyer, TX. 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 submit to EPA 1) a detailed plan to meet the arsenic MCL; 2) a cost analysis of the proposed plan; and 3) a construction schedule. This AO extends the compliance deadline to May 31, 2018 and supersedes the AO issued on February 10, 2014.
