Incorporating Supply Chain Resilience in RRAs and ERPs

United States

Safe Drinking Water Act (SDWA) section 1433 was revised by America's Water Infrastructure Act (AWIA) section 2013 and requires community water systems (CWS) serving more than 3,300 people to prepare (or revise) and certify risk and resilience assessments (RRAs) and emergency response plans (ERPs) to the U.S. Environmental Protection Agency (EPA) by specified deadlines every five years. Recertification deadlines are upon us, with deadlines occurring throughout 2025 and 2026. 

Natural hazards and malevolent acts have the potential to disrupt supply chains for a CWS’s treatment chemicals, potentially impacting treatment and operations. In this webinar, EPA will provide examples of how CWSs can address supply chain considerations in their RRAs and ERPs to build resilience to supply disruptions.
