The bulk of the analysis relies on data from the Risk-Screening Environmental Indicators (RSEI) model, which was developed by the U.S. Environmental Protection Agency. Manufacturing facilities with 10 or more employees in particular industries, which are in possession of chemical quantities above specific thresholds, are required to disclose information on their toxic emissions to the Toxics Release Inventory, a program administered by the EPA. The EPA releases this information online each year as required by the 1986 Emergency Planning and Community Right-to-Know Act. RSEI translates the TRI data, which is reported by weight, into values that reflect the relative risk to human health. These indicators allow regulators, companies and communities to assess risks and take action relative to a specific facility or waste stream.
