EGLE denied GFL's request to discharge Pit Raider (a bacterial augmentation product) from Arbor Hills' NPDES Outfall 001 because the proposed discharge concentration on Day 1 (41 mg/L) exceeded the Water Quality-Based Effluent Limits (11,000 µg/L or ~11 mg/L). The facility had requested a 13.63 mg/L average discharge concentration, but supporting calculations revealed higher initial concentrations over a multi-month application period.
Key data point: Pit Raider Day 1 discharge concentration 41 mg/L exceeds WQBEL of 11 mg/L; request denied 2022-03-23.
