EPA encourages the use of RSEI to help communities identify areas for further investigation.  However, it’s vitally important to accomplish this goal with quality TRI data.  Facilities are over-reporting their air emissions out of fear of EPA backlash for under-reporting.  As a result, models such as RSEI will predict relative risk scores for chemicals, industry, demographics, etc., that are not representative of actual release conditions possibly resulting in erroneous, unnecessary, and costly reaction on behalf of stakeholders.
