"incident_comment": "Throughout the week of July 27, the jobsite experienced sustained heavy rainfall. During this timeframe, the 21-inch manway cover on the FRAC tank was left open. This access point allowed excess stormwater to accumulate inside the tank, exceeding capacity and resulting in overfilling onto the surrounding paved lot. \n\nThe Temporary Sanitary Sewer Discharge Application process, administered under Loudoun Water Pretreatment, authorizes the disposal of passivation wastewater into the sanitary sewer system only. Discharge of any industrial wastewater to stormwater conveyances is strictly prohibited under this process and cannot be authorized by Loudoun Water under any circumstance. The discharge described above therefore constitutes an unauthorized release of industrial wastewater to the stormwater system.",
"location_comment": "The contents of the frac tanks had been emptied onto the paved lot due to heavy rainfall earlier in the week. Evidence observed by Pretreatment staff indicates that the wastewater flowed across the paved surface to a nearby stormwater inlet",
"closure_comment": "Frac tank overflow. The overflow of the wastewater reached state waters via stromdrains. 5-day letter received on 8-4-2026. No further action requried."
