SUMMARY: The U.S. Environmental
Protection Agency (EPA) announces the
availability of the EPA Web site,
‘‘Causal Analysis/Diagnosis Decision
Information System (CADDIS)’’—2007.
EPA’s National Center for
Environmental Assessment (NCEA) in
the Office of Research and Development
(ORD) led the development of the
CADDIS Web site in response to strong
demand within the EPA (e.g., the Office
of Water) and from stakeholders and
citizens across the United States seeking
a defensible method for determining
causes of ecological impairment.
CADDIS guides users through EPA’s
Stressor Identification process, with
interactive tools and methods,
worksheets, and examples to help

scientists and engineers evaluate causes
of biological impairment observed in
aquatic systems such as streams, lakes,
and estuaries.
Access: The CADDIS 2007 Web site
can be accessed via the Internet at
https://www.epa.gov/caddis/.

further information about CADDIS,

SUPPLEMENTARY INFORMATION:
Thousands of water bodies in the
United States have been reported to
have an ‘‘unknown’’ cause of
impairment. To formulate appropriate
management actions for impaired water
bodies, it is critical to identify the
causes of biological impairment (e.g.,
excess fine sediments, nutrients, or
toxic substances). Effective causal
analyses call for knowledge of the
mechanisms, symptoms, and stressorresponse relationships for various
stressors, as well as the ability to use
that knowledge to draw appropriate,
defensible conclusions. NCEA
developed CADDIS, a Web-based
decision support system, to help
regional, state, and tribal scientists
perform causal analyses. With this
release, CADDIS will also help scientists
find, access, organize, and share
information useful for causal
evaluations of impairment in aquatic
systems. It is based on EPA’s Stressor
Identification process, which is an EPArecommended method for identifying
causes of impairments in aquatic
environments. EPA released the first
version of CADDIS in 2006, after
addressing comments from the public
and independently selected, external
peer reviewers. The first release of
CADDIS included a step-by-step guide
to conducting causal analysis,
downloadable worksheets and
examples, a library of conceptual
models, and links to useful information
sources.
CADDIS 2007 adds considerable
power and usability to the first release.
Namely, CADDIS ecologists and Web
specialists made the following changes:
• Added eight modules, each
describing a common stressor or
candidate cause of biological
impairment; the stressor modules
include metals, sediments, nutrients,
dissolved oxygen, temperature, ionic
strength, flow alteration, and
unspecified toxic chemicals.
• Added material on data analysis
including:
Æ Information on how nine analytical
methods (e.g., scatter plots, linear
regression, predicting environmental

conditions from biological observations,
quantile regression and species
sensitivity distributions) can be used to
analyze causal relationships.
Æ CADStat, a downloadable software
package for analyzing data using a
variety of exploratory and statistical
approaches.
Æ SSD Generator, a tool for deriving
species sensitivity distributions.
Æ Databases of stressor-response
information including chronic
exposure-response relationships and
species sensitivity distributions for
metals from laboratory tests; and
stressor-response associations from field
observational data for metals and
sediments.
• Greatly expanded the conceptual
model library by adding generic
conceptual models for common causes
of biological impairment.
• Developed an interactive Flashbased conceptual model diagram for one
common stressor (phosphorus), which
provides source citations for cause-andeffect linkages shown in the diagram.
(The CADDIS team anticipates this part
of the site will expand to include other
common stressors and—at some point in
the future—harness information
collaboratively from the greater
scientific community.)
• Updated CADDIS’s underlying
code, which adheres to EPA’s latest Web
guidelines, and—similar to the first
release—continues to maintain
accessibility and 508 compliance.
The CADDIS 2007 release provides
users with state-of-the-art causal
assessment information and tools for
determining why aquatic systems are
biologically impaired. Ultimately, use of
the CADDIS Web site translates to
healthier ecosystems within the United
States, while serving as an example
stressor identification tool for our global
environment.

Notice of public comment
period.
SUMMARY: EPA is announcing a 45-day
public comment period for the external
review draft document titled, ‘‘An
Exploratory Study: Assessment of

The draft document was prepared by the
National Center for Environmental
Assessment (NCEA) within EPA’s Office
of Research and Development.
For the external scientific peer
review, EPA has contracted with Eastern
Research Group (ERG) to convene an
independent panel of experts and

for the external peer-review workshop
will be announced in a separate Federal
Register notice. The public comment
period and the external peer-review
workshop are separate processes that
provide opportunities for all interested
parties to comment on the document. In
addition to consideration by EPA, all
public comments submitted in
accordance with this notice will also be
forwarded to EPA’s contractor for the
external peer-review panel’s
consideration prior to the workshop.
EPA is releasing this external review

SUPPLEMENTARY INFORMATION:
I. Information About the Document
The purpose of this report is to
describe an exploratory investigation of
potential dioxin exposures to artists and
hobbyists who use ball clay to make
pottery and related products. Dermal,
inhalation and ingestion exposures to
clay were measured at the ceramics art
department of Ohio State University in
Columbus, Ohio. Estimates of exposure
were made based on measured levels of
clay in the studio air, deposited on
surrogate food samples and on the skin
of artists. The measurements were made
in two separate studies, one in April
2003 and one in July 2004. This draft
assessment combines the results of these
two studies.
