Regions 1-10 Drinking Water Branch Chiefs, Regions 1-10 Drinking Water Enforcement Managers, Regions 1-10 Compliance Assistance Coordinators, Regions 1-10 We have noticed that some states are reporting chemical and radionuclide maximum contaminant level (MCI,) violations to the Safe Drinking Water Information System/Federal System (SDWIS/Fed) using an inappropriate compliance period end date (i.e.. the date entered extends beyond the appropriate compliance period for the contaminant} s] at issue). This memorandum clarifies that, consistent with SDWIS data entry instructions, primacy agencies are to report MCL violations for these contaminants with a compliance period end date that is the date the monitoring period ends. Wre will keep you informed if there are updates to these reporting requirements. Please also remind your states that a public water system (PWS) with an ongoing, uncorrected MCL violation must continue to collect samples in accordance with the monitoring and reporting requirements established by regulation for that contaminant, and states must report new MCL violations to SDWIS/Fed with the appropriate compliance period end date. ------- Please note these new MCL violations will each contribute five points to a PWS's Enforcement Targeting Tool (ETT) score. Please take appropriate action to ensure that uncorrected violations are addressed in accordance with EPA's 2009 Safe Drinking Water Act Enforcement Response Policy, Each PWS with ongoing, uncorrected MCL violations must also provide the required public notifications. We thank you for your help in ensuring the consistent reporting of compliance period end dates to SDWIS/Fed, If you have any questions, please contact Ken Harmon of the Office of Compliance at 202-564-7049, or Ed Moriarty at 202-564-3864. cc: Mindy Eisenberg, Chief, Protection Branch, Drinking Water Protection Division, Office of Ground Water and Drinking Water Loren Denton, Chief, Municipal Enforcement Branch Water Enforcement Division, Office of Civil Enforcement Martha Segall, Chief, Water Branch, Monitoring, Assistance, and Media Division, Office of Compliance ------- |
