  • ChemSTEER
    The Chemical Screening Tool for Exposures and Environmental Releases (ChemSTEER) is a personal computer-based software program. ChemSTEER uses established EPA methods to generate screening-level estimates of environmental releases of and worker exposures to chemicals manufactured and used in industrial and commercial operations. The tool also contains data and estimation methods to assess situations involving many common industrial / commercial sectors (e.g., automotive refinishing) and chemical functional uses (e.g., surfactant in hard surface cleaner). ChemSTEER is currently applied in EPA's New Chemicals Program. In the future, engineers and technical users may find the tool helpful in assessing exposures and releases from workplaces.

  • Community Air Screening How-To Manual

FOSTTA (Forum on State and Tribal Toxics Action) is a mechanism by which state and tribal officials jointly, and in cooperation with EPA, address toxics-related issues. The Forum is designed to foster and improve communication and coordination among states, tribes, and EPA.

  • Internet Geographical Exposure Modeling System/Chemical Safety Mapper (IGEMS/CSM)
    The new GEMS is a modernization of OPPT's older Graphical Exposure Modeling System and PCGEMS tools. GEMS brings together in one system several EPA environmental fate and transport models and the environmental data needed to run them. GEMS includes models and data for ambient air, surface water, soil, and ground water, and makes the models much easier to use than their stand-alone counterparts. The GEMS models estimate environmental concentrations that can be used by communities or environmental groups in exposure and risk assessments for local populations.

    With enhanced GIS capability, the IGEMS/CSM models estimate environmental concentrations that can be used by communities or environmental groups in exposure and risk assessments for local populations.

  • Risk Screening Environmental Indicators
    The RSEI model is a personal computer-based, priority setting, screening-level tool that evaluates the hazard and relative risk-related impacts of toxic chemical releases and transfers from industrial facilities. RSEI integrates information on the amount of chemicals released to the environment, the relative long-term toxicity of these chemicals to people outside the workplace, the degree to which people are potentially exposed, and the estimated size of the exposed population.

    Communities can use RSEI, in a comparative fashion, to quickly focus on certain sources of risk that warrant further investigation. The model's pounds-based, hazard-based and risk-related perspectives can be used to examine trends, to rank and prioritize chemicals and industry sectors for strategic planning, to conduct risk-related targeting, and to help investigate environmental justice issues.
