Please clarify if">90" means >90% reduction of <br /> BOD and TSS between the influent and post treatment effluent, and the operational procedure when <br /> these sampling or monitoring parameters fall out of range: i.e. Recirculate, adjust the alkalinity feeder, <br /> taking the system off-line, etc. Please submit an addendum that will address these issues to EHD for <br /> review by 10/27/2022. <br /> 4) Exhibit 2 of the Plan indicated a Solid Pump Vault and a tight line extending from Building 2 (Fuel Tank <br /> Storage Building) which is adjacent to Building 3 (Truck Wash Center), to Building 1 (Gas Station & <br /> Truck Stop).
