CHICAGO — The Environmental Protection Agency issued a compliance plan requiring the Bad River Band of Lake Superior and Chippewa Indians to correct Clean Water Act violations at the wastewater treatment facilities located on the Tribe’s northern Wisconsin reservation, according to a press release.

The Bad River Band must upgrade plant operations to correct the violations by January 31, 2014.

Violations include failure to meet permit reporting requirements and failure to comply with permit effluent limits for phosphorus, E. coli, total suspended solids and biochemical oxygen demand, noted the release.

EPA will monitor the facilities to ensure that they meet compliance plan requirements and may take more formal action if violations are not corrected.
