Impact/Purpose:
StEWI is a software tool for providing standardized and combined facility based emissions and waste data from EPA inventories.
Description:
The USEPA provide databases that agglomerate data provided by companies or states reporting emissions, release, wastes generated and other activities to meet statutory requirements. Examples of these databases, often referred to as inventories, include the National Emissions Inventory (NEI), Toxic Release Inventory (TRI), Discharge Monitoring Report (DMR), and Biennial Hazardous Waste Report (RCRAInfo). These inventories can be used for a wide variety of environmental reporting and modeling purposes to characterize conditions in the US but can be particularly valuable for providing input into far-field exposure models, occupational exposure models, and for tracking chemical contamination in products. Users of these inventories are often challenged to find, retrieve and interpret these data due to the unique systems/schemes used to describe, format and dispense them that are not consistent across inventories. Combining these data from more than one inventory presents challenges, as information to link facilities, chemicals and industries is not inherent in these data sources, and because overlap exists that could result in double-counting or other erroneous estimation if not acknowledged and handled. To address these challenges, a system called Standardized Emission and Waste Inventories (StEWI) is being developed. StEWI is a Python module that can be used directly to retrieve standardized facility or emission data, or by other applications such as high-throughput exposure models. StEWI can be used to develop chemical release information for workflows being developed for the EPA program offices and state partners.
