Document Description
The Class 2 Permit Modification allows Boeing to reroute the extracted groundwater from the Area II RD-9 UV/Peroxidation facility and treat it at the Area II Road Air Stripping facility. In addition, the Permit Modification would add activated carbon canisters to the downstream liquid discharge for polishing the effluent while Boeing tests for additional constituents that may be present and which the air stripping system alone may be unable to remediate. Treated discharge from the groundwater facilities is discharged to channels that enter an on-site reservoir not used for drinking water. The Class 2 Permit Modification also modifies the sampling and inspection frequencies, generally to lower both frequencies, and adds sampling analytical requirements.
