The bill mandates the Environmental Protection Agency (EPA) to establish a comprehensive protocol for evaluating and addressing the cumulative public health risks stemming from multiple environmental stressors. This protocol must consider impacts from global climate change, such as extreme weather and sea level rise, alongside exposure to various pollutants regulated under major environmental laws. The EPA Administrator is required to publish a proposed protocol for public comment and hearings, then finalize and implement it within specific timelines. Furthermore, the legislation directs the EPA to identify at least 100 environmental justice communities that have experienced a disproportionately high number of environmental law violations over the past five years. For these identified communities, the Administrator must conduct an in-depth analysis to determine the root causes of these violations, engaging with residents in the process. The EPA will then propose and implement specific measures, in coordination with state and local agencies, to significantly reduce the number of environmental violations in these overburdened areas.
