Federal Regulations, 40 CFR 132, Tables 1 and 2

EPA disapproved the acute and chronic aquatic life criteria for copper and nickel (Wis. Adm. Code NR 105, Tables 2 and 6), a chronic aquatic life criterion for endrin (Wis. Adm. Code NR 105, Table 5) as being inconsistent with Tables 1 and 2 of the Great Lakes Guidance at 40 CFR 132. In addition, EPA also disapproved Wisconsin's failure to adopt and submit to EPA a chronic aquatic life water quality criterion for selenium as required by 40 CFR 132.3(b). Pursuant to the Great Lakes Guidance, these water quality criteria are replaced by corresponding federal water quality criteria contained at 40 CFR 132, Tables 1 and 2.
