• If all parameters are met, switch the flow to discharge. • Collect samples from the discharge and measure and record the dissolved oxygen level. Visually inspect the discharge flow to verify there is no scouring as the water flows into the wetland. The system operator must remain on site while the system is operating, checking the system components and filtration performance at regular intervals using the daily job log as a minimum amount of testing and documenting of results. If the parameters get out of compliance, the Hach controllers will automatically switch the discharge to recycle. With the system in recycle, make corrections to address the treatability issue and if remedied, switch back to discharge. Any switch to recycle needs to be recorded in the daily job log and include the reason for the change. 3.2.5 Alarm Conditions and Response If the parameters get out of compliance, the Hach controllers will automatically switch the discharge to recycle and trigger both an audible and visual alarm. With the system in recycle, make corrections to address the treatability issue and if remedied, switch back to discharge. Any switch to recycle needs to be recorded in the daily job log and include the reason for the change as well as corrections made to the system to get the discharge back into compliance. 3.2.6 System Shutdown Filter system shutdown requires only stopping the filter feed pump, CO2 and metering pump and reading and recording the discharge volume totalizer. City of Everett EVERETT Reviewed for Permit 10/20/2021 WASHINGTON 3.3 Data Management and Reporting 3.3.1 Daily Treatment Logs A daily job log form will be used to track system operation and discharge compliance (see attached example). These forms will be retained in a binder within the water quality monitoring box for review by the project engineer. A monthly recap sheet will be generated and provided for inclusion in the Discharge Monitoring Reports. 12
