of the 3-year air screening pilot project in Baltimore, Maryland.
It illustrates the development and implementation of a new methodology
for evaluating air quality impacts of toxic air pollutant emissions.
The risk screening methodology allowed the partnership to evaluate
potential human health risks from more than 175 chemicals emitted
to the air by more than 125 facilities in and around the partnership
neighborhoods. The case study presents the process used as well

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

identify and inventory local sources of air pollutants, review
pollutant sources to identify known hazards that may present a
potential health risk to the community and set priorities and
develop plans for improvement.
- Community
Health Status Indicators Project

The Community Health Status Indicators (CHSI) Project was launched
in response to grassroots requests from local health officials for

with an assessment of needs, quantification of vulnerable populations,
and measurement of preventable disease, disability, and death. In
one brief document, local health officials can see, react, and act
upon the data provided.

to and risk from the release of chemicals to the environment.
E-FAST can be used by community groups to estimate exposure and risk
from such areas as industrial/commercial activities and the use and
disposal of consumer products.

of the Forum on State and Tribal Toxics Action (FOSTTA). 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.

references available for interlibrary loan.
- 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.
