Did not comply with wet weather plant operational requirements, as described in Provision VI.C.5.c.iv(b). INF flow was not maximized while discharge from the Westside Transport/Storage Structure to Discharge Point 001 occurred. This resulted in approximately 6.6 MG of wastewater being discharged as decant rather than 3.1 MGD receiving primary treatment and 3.5 MGD receiving secondary treatment at OSP.
