RAIMI - Regional Air Impact Modeling Initiative

RAIMI: A Practical Approach for Implementing Cumulative Type Assessments on a Localized Scale

The U.S. Environmental Protection Agency (EPA),
Region 6, established the Regional Air Impact Modeling Initiative (RAIMI) to evaluate the potential for health impacts as a result of exposure to multiple contaminants from multiple sources, at a community level of resolution. Often when evaluating permitting and enforcement actions, EPA needs to consider the bigger picture as opposed to the traditional source-by-source, program-by-program approach. Such an approach has blindly focused on selective units, often located among a "forest" of others impacting the same receptor neighborhoods. As a result, goals of RAIMI focused on developing the capability to conduct localized assessments in a timely enough manner so as to actually be useful in day-to-day permitting and enforcement activities, that would obviously support cross-program participation, and that would provide results at a level of resolution and traceability that serve as an asset to stakeholders needing to evaluate and implement solutions.
