Risk-Screening Environmental Indicators is the EPA model that turns the raw pounds in the TRI into a comparative risk score. It weights each reported release by the chemical's toxicity and models how it disperses and reaches people, so a small release of a potent compound near a population can outrank a large release of a benign one far from anyone.
RSEI is a screening tool, not a measurement of harm to any individual — its value is in ranking and trend, letting an analyst compare facilities and watch a site's risk profile move over time. The platform pulls RSEI as a committed [reference] dataset scoped to a site's geography, and treats a score as an [inference] about relative chronic risk rather than a [verified] exposure. Its inputs are only as current as the TRI year it was run on.
