The project includes the following proposed improvements to the IWTP, which are detailed further in the Basis of Design Report: o Addition of a new on-site biological "aerated gravel bed" (AGB) treatment system to allow discharges of treated industrial wastewater to Puget Sound in accordance with NPDES permit discharge limitations. o Addition of a 5 Million gal fully buried prestressed concrete storage tank at the AGB site ("AGB Tank") to expand high BOD industrial wastewater storage capacity. o Splitting existing Lagoon 3 (low BOD storage) into two lagoons using a berm, resulting in a new high BOD lagoon ("Lagoon 4") and a reduced size low BOD lagoon ("Lagoon 3"). o Realignment of the existing Puget Sound outfall to go around the proposed expanded footprint of Lagoons 3 and 4. o Modifications to existing IWTP dissolved air flotation (DAF) system, including replacement of DAF units and associated infrastructure with larger capacity units. o Modifications to existing IWTP solids handling system, including replacement of the existing decant tanks with a gravity thickener unit. o Modifications to controls and flow routing schemes to integrate new and existing infrastructure, as detailed in Section 7 of the Basis of Design Report.
