On November 16, 2023, Region III issued an Administrative Order on Consent (AOC) to Somerset Township Municipal Authority Oakridge System (Somerset) to assure its compliance with the requirements of Section 1433 of the SDWA, as amended by the America's Water Infrastructure Act (AWIA) of 2018. Section 1433 required that Public Water Systems (PWSs) serving over 3,300 people conduct a Risk and Resilience Assessment (RRA) of the PWS including risks of malevolent acts and natural hazards . No later than six months after completion of the RRA, the PWS had to prepare or revise an Emergency Response Plan (ERP) to address the RRA findings. Covered PWSs had to certify to EPA that they had conducted the RRA and revised the ERP by the deadlines specified by AWIA. Somerset had not complied with the requirement to prepare or revise the ERP by the specified deadline. EPA directly implements the Section 1433 requirements, but EPA has notified Pennsylvania of the action against the facility.
