Title 42 › Chapter CHAPTER 6A— - PUBLIC HEALTH SERVICE › Subchapter SUBCHAPTER XII— - SAFETY OF PUBLIC WATER SYSTEMS › Part Part D— - Emergency Powers › § 300i–2

Last updated Apr 6, 2026|Official source

Summary

Require community water systems that serve more than 3,300 people to check the risks to their system and how well it can bounce back. The check must look at risks from bad actions and natural hazards, the strength of pipes and other built parts and electronic systems, monitoring, money matters, chemicals used, and how the system is run and maintained. Systems may also look at capital and operational needs. Systems must tell the Administrator they did the check by these dates: March 31, 2020 (100,000+ people), December 31, 2020 (50,000–99,999), and June 30, 2021 (>3,300–49,999). They must review the check at least every 5 years and certify any review or update. Each system must prepare or update an emergency response plan based on the check and certify to the Administrator as soon as reasonably possible after October 23, 2018, but no later than 6 months after finishing the check. Keep the check and plan for 5 years. Coordinate with local emergency planning groups. The Administrator will give guidance to systems under 3,300 people and may accept recognized technical standards instead of the exact check or plan. The Administrator will run a Drinking Water Infrastructure Risk and Resilience Program and may give grants in fiscal years 2020 and 2021 to help carry out emergency-response projects tied to the plan. Grant money can pay for things like detection equipment, fencing, tamper-proofing, treatment upgrades, cyber/financial improvements, training, chemical handling fixes, security screening, emergency power or water equipment, and alternative source or flood protections. Grants cannot pay for personnel or for monitoring, operation, or maintenance. Up to $5,000,000 per year may be used for urgent technical help, and up to $10,000,000 per year may be for systems serving fewer than 3,300 people or certain nonprofits. Congress authorized $25,000,000 for each of fiscal years 2020 and 2021. Resilience = ability to withstand or quickly recover from a bad act or natural event. Natural hazard = a natural event like an earthquake, tornado, flood, hurricane, wildfire, or changes in water flow.

(2)The Administrator, not later than August 1, 2019, after consultation with appropriate departments and agencies of the Federal Government and with State and local governments, shall provide baseline information on malevolent acts of relevance to community water systems, which shall include consideration of acts that may—
(A)substantially disrupt the ability of the system to provide a safe and reliable supply of drinking water; or
(B)otherwise present significant public health or economic concerns to the community served by the system.
(3)(A)Each community water system described in paragraph (1) shall submit to the Administrator a certification that the system has conducted an assessment complying with paragraph (1). Such certification shall be made prior to—
(i)March 31, 2020, in the case of systems serving a population of 100,000 or more;
(ii)December 31, 2020, in the case of systems serving a population of 50,000 or more but less than 100,000; and
(iii)June 30, 2021, in the case of systems serving a population greater than 3,300 but less than 50,000.
(B)Each community water system described in paragraph (1) shall review the assessment of such system conducted under such paragraph at least once every 5 years after the applicable deadline for submission of its certification under subparagraph (A) to determine whether such assessment should be revised. Upon completion of such a review, the community water system shall submit to the Administrator a certification that the system has reviewed its assessment and, if applicable, revised such assessment.
(4)A certification required under paragraph (3) shall contain only—
(A)information that identifies the community water system submitting the certification;
(B)the date of the certification; and
(C)a statement that the community water system has conducted, reviewed, or revised the assessment, as applicable.
(5)No community water system shall be required under State or local law to provide an assessment described in this section (or revision thereof) to any State, regional, or local governmental entity solely by reason of the requirement set forth in paragraph (3) that the system submit a certification to the Administrator.
(b)Each community water system serving a population greater than 3,300 shall prepare or revise, where necessary, an emergency response plan that incorporates findings of the assessment conducted under subsection (a) for such system (and any revisions thereto). Each community water system shall certify to the Administrator, as soon as reasonably possible after October 23, 2018, but not later than 6 months after completion of the assessment under subsection (a), that the system has completed such plan. The emergency response plan shall include—
(1)strategies and resources to improve the resilience of the system, including the physical security and cybersecurity of the system;
(2)plans and procedures that can be implemented, and identification of equipment that can be utilized, in the event of a malevolent act or natural hazard that threatens the ability of the community water system to deliver safe drinking water;
(3)actions, procedures, and equipment which can obviate or significantly lessen the impact of a malevolent act or natural hazard on the public health and the safety and supply of drinking water provided to communities and individuals, including the development of alternative source water options, relocation of water intakes, and construction of flood protection barriers; and
(4)strategies that can be used to aid in the detection of malevolent acts or natural hazards that threaten the security or resilience of the system.
(c)Community water systems shall, to the extent possible, coordinate with existing local emergency planning committees established pursuant to the Emergency Planning and Community Right-To-Know Act of 1986 (42 U.S.C. 11001 et seq.) when preparing or revising an assessment or emergency response plan under this section.
(d)Each community water system shall maintain a copy of the assessment conducted under subsection (a) and the emergency response plan prepared under subsection (b) (including any revised assessment or plan) for 5 years after the date on which a certification of such assessment or plan is submitted to the Administrator under this section.
