This beneficial use will be considered restored when the following conditions are met:

There are no observed ongoing occurrences of sludge deposits, oil sheens, scum and other objectionable materials; specifically materials that produce color, odor, or other nuisances.

OR

If Combined Sewer Overflows (CSOs) are a significant cause of aesthetic impairments and the CSOs are being addressed under an approved long term control plan or other legally-binding document, this BUI may be considered restored. Where long-term remedies may take several years to be fully implemented, it may be necessary to develop short-term control strategies.

AND

If Municipal Separate Storm Sewer Systems (MS4s) are a significant cause of aesthetic impairments and the MS4 is regulated under an NPDES Permit or other legally-binding document, this BUI may be considered restored.

Notes

• Aesthetic impairments due to algae or excessive nutrient loading will be addressed under BUI 8.
• Natural physical features (e.g., woody debris, logjams, rootwads) and excessive turbidity following storm events or due to agricultural activities are not considered an impairment under this BUI.
