System of Systems Tools
- Multimedia, Multi-pathway, Multi-receptor Exposure and Risk Assessment (3MRA) - This technology provides the ability to conduct screening-level risk-based assessment of potential human and ecological health risks resulting from long term (chronic) exposure to HWIR chemicals released from land-based waste management units (WMUs) containing currently listed waste streams.
- Speciated Modeled Attainment Test Documentation (SMAT Documentation) - (PDF, 13 pp., 436 KB) EPA has issued draft guidance (EPA, 2001) that describes a procedure for combining monitoring data with outputs from simulation models to estimate future concentrations of PM2.5 mass. The guidance recommends that model predictions be used in a relative sense to estimate changes expected to occur in each major PM2.5 species.
- Council for Regulatory Environmental Modeling Knowledge Base (CREM Models Knowledge Base) - Database containing an inventory of EPA's environmental models. [Metadata]
