Enforcement Targeting Tool
Overview of the ETT List (formerly known as the Significant Non Complier List)
The ETT (formerly known as the SNC List) is a tool created by the Environmental Protection Agency (EPA) to help State Drinking Water (DW) Programs track Public Water Systems (PWSs) that are deemed by EPA to be significantly out of compliance with the Safe Drinking Water Act (SDWA) regulations. This list is generated quarterly by EPA based on the PWS information transferred to them from the state of Alaska's DW Program database, SDWIS/State. The ETT displays a total "score" based on the violations received by PWS which has not been returned to compliance (RTCd). EPA has assigned a point value to each violation with a higher "weight" being place on health-based violations. In addition to these violations EPA will add the number of years the PWS has been out of compliance to determine the total system ETT score. PWSs with a score of 11 or higher are considered a national enforcement priority.
This list is used by several agencies such as Village Safe Water (VSW), Municipal Grants & Loans (MG&L), Rural Utility Business Advisor (RUBA) Program, EPA, and native health corporations as an indicator of capacity, to determine grant eligibility, and to prioritize enforcement. If you find your system on this list we recommend contacting the Environmental Program Specialist (EPS) assigned to the area, their contact information is available at the bottom of the list. The EPS can assist in identifying why the PWS is on the list and what steps are needed to come back into compliance (i.e. be removed from the list).
