The GLI Clearinghouse is a central resource for developing water quality standards in the Great Lakes watershed.
The GLI Clearinghouse is a central resource for developing water quality standards in the Great Lakes watershed. It contains information on criteria, toxicity data, exposure parameters and other supporting documents. It can be used to help establish water quality criteria, permit discharge limits, Total Maximum Daily Loads, Remedial Action Plans and Lakewide Management Plans.
Who Should Use the GLI Clearinghouse?
In particular, States and Tribes can use the Clearinghouse to help derive criteria for pollutants without specific numeric criteria published in 40 CFR Part 132 of the GLI.
The target audience for the Clearinghouse is State and Tribal environmental agencies in the Great Lakes basin, as well as other interested parties with a technical background.
