COVID Preparedness, Response, and Effective Planning for Advanced Requirements by the Executive Branch Act of 2020 or the COVID PREPARE Act of 2020 This bill requires federal agencies to submit to Congress plans for responding to any resurgence of COVID-19 (i.e., coronavirus disease 2019). Specifically, each agency shall submit (1) an initial report detailing an action plan, informed by research and best practices learned from the onset of COVID-19 and previous presidentially declared emergencies, for addressing the needs and mitigating and eliminating the risks and challenges associated with any resurgence in COVID-19 cases; and (2) subsequent reports, on a quarterly basis until the President ends the declared emergency, that update the details submitted in the plan. The initial report shall include agency priorities for preparing for and responding to any resurgence; measurable goals specific to priorities and a time line for addressing each priority; anticipated challenges to addressing priorities and how the agency will address such challenges; how the agency will consult with Congress, the public, state and municipal governments, and relevant stakeholders while working remotely; and how the agency plans to issue relevant guidance to entities under the jurisdiction of the agency.
