Preliminary Assessment of Climate Change Effects on Stream and 
River Biological Indicators

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of public comment period.

-----------------------------------------------------------------------

SUMMARY: EPA is announcing a 30-day public comment period for the draft 
document titled, ``Preliminary Assessment of Climate Change Effects on 
Stream and River Biological Indicators'' (EPA/600/R-07/085). The 
document was prepared by the National Center for Environmental 
Assessment within EPA's Office of Research and Development.
    EPA is releasing this draft document solely for the purpose of pre-
dissemination peer review under applicable information quality 
guidelines. This document has not been formally disseminated by EPA. It 
does not represent and should not be construed to represent any Agency 
policy or determination. EPA intends to consider any public comments 
submitted in accordance with this notice when revising the document.

DATES: The 30-day public comment period begins August 10, 2007, and 
ends September 10, 2007. Technical comments should be in writing and 
must be received by EPA by September 10, 2007.

ADDRESSES: The draft ``Preliminary Assessment of Climate Change Effects 
on Stream and River Biological Indicators'' is available primarily via 
the Internet on the National Center for Environmental Assessment's home 
page under the Recent Additions and the Data and Publications menus at 
http://www.epa.gov/ncea. A limited number of paper copies are available 

from the Technical Information Staff of the National Center for 
Environmental Assessment (NCEA-TIS). Please contact the Technical 
Information Staff by telephone at 202-564-3261 or by facsimile at 202-
565-0050. If you are requesting a paper copy, please provide your name, 
your mailing address, and the draft document title, ``Preliminary 
Assessment of Climate Change Effects on Stream and River Biological 
Indicators.''
    Comments may be submitted electronically via http://www.regulations.gov
, by mail, by facsimile, or by hand delivery/

courier. Please follow the detailed instructions provided in the 
SUPPLEMENTARY INFORMATION section of this notice.

FOR FURTHER INFORMATION CONTACT: For information on the public comment 
period, contact the Office of Environmental Information Docket;

SUPPLEMENTARY INFORMATION: 

I. Information About the Project/Document

    This report describes projected effects of climate change on 
aquatic ecosystems and provides a preliminary analysis of possible 
effects on river and stream bioassessment programs. The report is 
intended for managers and scientists working on biological indicators, 
bioassessment, and biocriteria to provide them with information on the 
potential effects of climate change on indicator organisms used, 
initial strategies for adapting their programs to accommodate these 
environmental changes, and highlight possible next steps. The first 
step described in the report is an approach for identifying biological 
indicators sensitive to climate change; a case study next analyzes 
bioassessment data to detect possible climate change effects; and, 
finally, another analysis discusses methods for continuing to detect 
impairment under climate change. The results show that (1) Some 
biological indicators may be particularly sensitive to climate change; 
(2) depending on species loss rates, magnitude of temperature changes, 
and number samples, effects may be detected in 15 to 100 years; and (3) 
climate change effects may decrease the ability of states to 
discriminate between reference and impaired sites. The report concludes 
with recommendations for more in-depth assessments in different U.S. 
regions and further dissemination and coordination of information 
across EPA and states.
