Federal Register / Vol. 73, No. 72 / Monday, April 14, 2008 / Notices
draft document, Nitrogen Dioxide
Health Assessment Plan: Scope and
Methods for Exposure and Risk
Assessment. This document was
released for public review and comment
in September, 2007 and was the subject
of a consultation with the Clean Air
Scientific Advisory Committee (CASAC)
on October 24 and 25, 2007. Comments
received from that consultation have
been considered in developing the draft
risk and exposure assessment
documents being released at this time.
The draft documents convey the
approach taken to assess exposures to
ambient NO2 and to characterize
associated health risks, as well as to
present the results of those assessments.
These draft documents will be available
online at: https://www.epa.gov/ttn/
naaqs/standards/nox/
s_nox_cr_rea.html.
The EPA is soliciting advice and
recommendations from the CASAC by
means of a review on the draft
documents at an upcoming public
meeting of the CASAC. A Federal
Register notice will inform the public of
the date and location of that meeting.
Following the CASAC meeting, EPA
will consider comments received from
the CASAC and the public in preparing
a second draft risk and exposure
assessment report. The release of the
second draft report will be followed by
another CASAC meeting and ultimately
by a final risk and exposure assessment
report.

Acting Director, Office of Air Quality Planning

SUPPLEMENTARY INFORMATION: Ecological
risk assessment (ERA) is a process for
analyzing environmental problems and
is intended to increase the use of
ecological science in decision making in
order to evaluate the likelihood that
adverse ecological effects may occur or
are occurring as a result of exposure to
one or more stressors. Applying ERA
principles to watershed management
makes scientific information more
relevant to the needs of environmental
managers. Watershed ERAs are complex
because addressing impacts from
multiple sources and stressors on
multiple endpoints presents a scientific
challenge and because multiple
stakeholders have diverse interests. The
needs of managers and stakeholders
may change, and the need to take action
may require using the best available
information at the time, sometimes
before an ERA is completed. Therefore,
some flexibility of ERA methods is
needed when performing watershed
ERAs. It is also important that risk
assessors and managers interact
regularly and repeatedly.
This report supplements the
Guidelines for Ecological Risk
Assessment (U.S. EPA, 1998a) by
addressing issues unique to ecological
assessments of watersheds. Using
lessons learned from watershed ERAs,
the report presents guidance and
examples for scientists performing
watershed ecological assessments. The
report also can be useful to risk
assessors, watershed associations,
landscape ecologists, and others seeking
to increase the use of environmental
assessment data in decision making.

Each activity and phase of the
watershed ERA process is explained
sequentially in this report. Guidance on
how to involve stakeholders to generate
environmental management goals and
objectives is provided. The processes for
selecting assessment endpoints,
developing conceptual models, and
selecting the exposure and effects
pathways to be analyzed are described.
Suggestions for predicting how multiple
sources and stressors affect assessment
endpoints are also provided; these
include using multivariate analyses to
compare land use with biotic
measurements. In addition, the report
suggests how to estimate, describe, and
communicate risk and how to evaluate
management alternatives.
