EPA will host Office Hours in December 2025 to assist community water systems (CWSs) with specific questions on completing or certifying Risk and Resilience Assessments (RRAs) and Emergency Response Plans (ERPs) under Safe Drinking Water Act (SDWA) section 1433 (also known as America’s Water Infrastructure Act section 2013). These one-on-one discussions with EPA will remain private.
While aimed at medium-sized CWSs serving 50,000-99,999 people who must certify their RRA by December 31st, all CWSs are welcome to register if slots are available.
