At #HackTheCapitol, EPA cyber branch chief Nushat Thomas says the EPA understands complaints from states and utilities that they lack the resources to comply with a new water cyber assessment rule.

She lists a bunch of resources and services that EPA offers.
Thomas: "We have training in place for those states who actually want to conduct the...assessment themselves." EPA developed a water-specific cyber checklist based on CISA's cross-sector cyber performance goals, "and we're training the states on how to utilize that checklist..."
EPA also made "an easy-to-use tool" that lets water utilities run through that checklist themselves.

Utilities can also register with the EPA to have the agency conduct the required assessments for them.
