# §300j–19g. Midsize and Large Drinking Water System Infrastructure Resilience and Sustainability Program

- (a) **Definitions—** In this section:
  - (1) **Eligible entity—** The term “eligible entity” means a public water system that serves a community with a population of 10,000 or more.
  - (2) **Natural hazard; resilience—** The terms “resilience” and “natural hazard” have the meanings given those terms in [section 300i–2(h) of this title](/usc/42/300i–2.md?p=h).
  - (3) **Resilience and sustainability program—** The term “resilience and sustainability [program](/usc/42/274l–1.md?p=4)” means the Midsize and Large Drinking Water System Infrastructure Resilience and Sustainability [Program](/usc/42/274l–1.md?p=4) established under [subsection (b)](#b).
- (b) **Establishment—** The [Administrator](/usc/42/4005.md?p=1) shall establish and carry out a [program](/usc/42/274l–1.md?p=4), to be known as the “Midsize and Large Drinking Water System Infrastructure Resilience and Sustainability [Program](/usc/42/274l–1.md?p=4)”, under which the [Administrator](/usc/42/4005.md?p=1), subject to the availability of appropriations for the resilience and sustainability [program](/usc/42/274l–1.md?p=4), shall award grants to eligible entities for the purpose of—
  - (1) increasing resilience to natural hazards and extreme weather events; and
  - (2) reducing cybersecurity vulnerabilities.
- (c) **Use of funds—** An eligible entity may only use grant funds received under the resilience and sustainability [program](/usc/42/274l–1.md?p=4) to assist in the planning, design, [construction](/usc/42/300s–3.md?p=7), implementation, operation, or maintenance of a [program](/usc/42/274l–1.md?p=4) or [project](/usc/42/13641.md?p=2) that increases resilience to natural hazards and extreme weather events, or reduces cybersecurity vulnerabilities, through—
  - (1) the conservation of water or the enhancement of water-use efficiency;
  - (2) the modification or relocation of existing drinking water system infrastructure made, or that is at risk of being, significantly impaired by natural hazards or extreme weather events, including risks to drinking water from flooding;
  - (3) the design or [construction](/usc/42/300s–3.md?p=7) of new or modified desalination facilities to serve existing communities;
  - (4) the enhancement of water supply through the use of watershed management and source water protection;
  - (5) the enhancement of energy efficiency or the use and generation of renewable energy in the conveyance or [treatment](/usc/42/11851.md?p=11) of drinking water;
  - (6) the development and implementation of measures—
    - (A) to increase the resilience of the eligible entity to natural hazards and extreme weather events; or
    - (B) to reduce cybersecurity vulnerabilities;
  - (7) the conservation of water or the enhancement of a water supply through the implementation of water reuse measures; or
  - (8) the formation of regional water partnerships to collaboratively address documented water shortages.
- (d) **Application—** To seek a grant under the resilience and sustainability [program](/usc/42/274l–1.md?p=4), an eligible entity shall submit to the [Administrator](/usc/42/4005.md?p=1) an application at such time, in such manner, and containing such information as the [Administrator](/usc/42/4005.md?p=1) may require, including—
  - (1) a proposal of the [program](/usc/42/274l–1.md?p=4) or [project](/usc/42/13641.md?p=2) to be planned, designed, constructed, implemented, operated, or maintained by the eligible entity;
  - (2) an identification of the natural hazard risks, extreme weather events, or potential cybersecurity vulnerabilities, as applicable, to be addressed by the proposed [program](/usc/42/274l–1.md?p=4) or [project](/usc/42/13641.md?p=2);
  - (3) documentation prepared by a Federal, [State](/usc/42/201.md?p=f), regional, or local government [agency](/usc/42/8262.md?p=1) of the natural hazard risk, potential cybersecurity vulnerability, or risk for extreme weather events to the area where the proposed [program](/usc/42/274l–1.md?p=4) or [project](/usc/42/13641.md?p=2) is to be located;
  - (4) a description of any recent natural hazards, cybersecurity events, or extreme weather events that have affected the community water system of the eligible entity;
  - (5) a description of how the proposed [program](/usc/42/274l–1.md?p=4) or [project](/usc/42/13641.md?p=2) would improve the performance of the community water system of the eligible entity under the anticipated natural hazards, cybersecurity vulnerabilities, or extreme weather events; and
  - (6) an explanation of how the proposed [program](/usc/42/274l–1.md?p=4) or [project](/usc/42/13641.md?p=2) is expected—
    - (A) to enhance the resilience of the community water system of the eligible entity to the anticipated natural hazards or extreme weather events; or
    - (B) to reduce cybersecurity vulnerabilities.
- (e) **Report—** Not later than 2 years after November 15, 2021, the [Administrator](/usc/42/4005.md?p=1) shall submit to Congress a report that describes the implementation of the resilience and sustainability [program](/usc/42/274l–1.md?p=4), which shall include a description of the use and deployment of amounts made available to carry out the resilience and sustainability [program](/usc/42/274l–1.md?p=4).
