Risk Assessment Tools - RSEI Model
More on Cross-Cutting Programs
The Risk-Screening Environmental Indicators (RSEI) is a computer-based screening tool developed by OPPT that analyzes risk factors to put Toxics Release Inventory (TRI) release data into a chronic health context. RSEI is often used by government regulators, communities, journalists, industry and others to examine trends, identify important emissions situations for follow-up, support community-based projects and initially screen potential impacts of emissions.
- In 2007, OPPT updated the model and a new version, RSEI 2.1.5, was released in January 2008, which has data covering 1996-2005 and includes new features:
- Reporting facilities located using EPA's Locational Reference Tables (LRT)
- Additional site-specific information
- Chromium speciation
- Metals and metal compounds combined
- Updated toxicity weights
- In 2007, OPPT worked with a variety of clients to interpret and utilize risk-related information on industrial releases.
- In 2007, OPPT presented the RSEI model to various groups, including the American Petroleum Institute and at the annual TRI Conference, sponsored by EPA's Office of Environmental Information and the Environmental Council of the States.
- OPPT held workshops to train EPA regional staff on the RSEI model.
