Great Lakes Initiative (GLI) Toxicity Data Clearinghouse
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Great Lakes Initiative Toxicity Data Clearinghouse
(Clearinghouse) is available for use by States, Tribes, and other
interested parties. The online Clearinghouse, developed in cooperation
with the United States Environmental Protection Agency (USEPA)
Headquarters, Regions 2, 3, and 5, and the Great Lakes States and
Tribes, acts as a central location for toxicity data, exposure
parameters, and supporting documents used in deriving water quality
criteria and guidance values in the Great Lakes Basin.
FOR FURTHER INFORMATION CONTACT: Brian Thompson, Water Quality Branch
(WQ-16J), U.S. EPA, Region 5, Water Division, 77 West Jackson Blvd.,
Chicago, IL 60604, (312) 353-6066, [email protected].
SUPPLEMENTARY INFORMATION:
I. General Information
The Clearinghouse was developed to support implementation of the
Final Water Quality Guidance for the Great Lakes System (GLI). Data
from the Clearinghouse can be shared among States and Tribes to assist
them in developing or updating numeric water quality standards and
guidance values for the protection of aquatic life, human health, and
wildlife. In particular, States and Tribes can use the information in
the Clearinghouse to help derive criteria for pollutants without
specific numeric criteria published in the GLI (40 CFR Part 132).
Data in the Clearinghouse can be viewed online or downloaded in
spreadsheet format. The Clearinghouse includes PDF versions of ``fact
sheets,'' which provide methodology information on how State agencies
and USEPA derive criteria and guidance values. The Clearinghouse also
includes links to GLI-related documents, including Federal Register
notices and technical support documents, as well as formulas that allow
users to calculate criteria according to GLI methodologies. To access
the Clearinghouse go to http://www.epa.gov/gliclearinghouse.

Acting Deputy Regional Administrator, Region 5.
