The Respondent owns and/or operates a public water system as defined by the Safe Drinking Water Act (SDWA) and 40 C.F.R. Part 141.2, and is, therefore, subject to its requirements. The EPA found that the Respondent's public water system failed to comply with the requirements of the Stage 2 Disinfectants By-products Rule (Stage 2 DBPR,40 C.F.R. Part 141 Subpart V ) by failing to comply with the monitoring requirements for TTHM and HAA5 since the 2014 monitoring period. The Administrative Order requires compliance with these requirements.
