AWIA requires a community drinking water system serving more than 3,300 persons to conduct a risk and resilience assessment (RRA) and prepare an emergency response plan (ERP). AWIA was signed into law on October 28, 2018, and is overseen by the EPA.
A RRA analyzes the risk of manmade malevolent and naturally occurring threats to a water treatment/distribution facility’s infrastructure and the availability and effectiveness of existing resources for response actions.
An ERP describes the utility’s strategies, resources, plans, and procedures to prepare for and respond to an incident (main break, water contamination, flooding, etc.) including strategies and resources to improve the resilience of the system, respond to a malevolent act or natural hazard, obviate or significantly reduce the impact of a malevolent act or natural hazard; and detect malevolent acts or natural hazards.
Deadlines for preparing and submitting RRAs for Tier 1 (>100,000 service population) and Tier 2 (>50,000) systems are in the 2020 calendar year, and Tier 3 (>3,000) deadlines are in the 2021 calendar year.
