On July 6, 2011, the Bad River Band of Lake Superior Tribe of Chippewa Indians adopted Water Quality
Standards (WQS). One of the three key components of the WQS is an antidegradation policy, which
protects existing uses and prevents clean waters from being unnecessarily degraded. Under the
antidegradation policy, each waterbody is assigned to a tier that provides a basis for addressing activities
that would, or have the potential to, lower the quality of a body of water. Tiers identified in the Tribe’s
antidegradation policy include: Outstanding Tribal Resource Waters (Tier 3 waters), Outstanding Resource
Waters (Tier 2.5 waters), and Exceptional Resource Waters (Tier 2 waters). No new or increased discharges
or alterations of the background conditions are allowed to Outstanding Tribal Resource Waters (Tier 3
waters); however, a short-term, temporary lowering of water quality may be allowed provided that such
discharges will arise entirely from one of the actions listed in provision E.3.ii. in the Tribe’s WQS and meets
the antidegradation demonstration and decision requirements described in provisions E.4.iv. and E.5.ii. in
the Tribe’s WQS. (Read More)
