WQA = Water Quality Analysis |
|
1Action may take two forms: submittal of a Total Maximum Daily Load (TMDL) or submittal of a Water Quality Analysis (WQA). TMDLs are developed when a given substance or stressor is exceeding water quality standards. WQAs are developed when supplemental data indicate the waterbody is meeting water quality standards for that substance. This list is subject to change.
2Action to address this listing has yet to be determined, but will likely include a watershed protection plan. |
