Compliance conference regarding dewatering system.

Corrective actions completed 1/24 after failed Site Prep.
- installed riser pipe on outlet to pull water from top of column and increase last pond volume. Filter fabric on top of pipe was not succesful due to backing up water and was removed.
- installed sandbags to direct water into grassy swale instead of straight to pond

Conference and inspection of dewatering activity conducted Wednesday 1/25 @ 8 AM with RP Zach
Dewatering pond discharge was clear at time of inspection prior to construction activity starting for the day. No visible plume or issues. The gravel baffles are working to treat sediment and capture floating foam in the middle chamber to prevent discharge. Sandbags were containing water in the swale channel.

Later @ 4 PM follow up inspection conducted by MMJ and discharge plume in swale channel and pond was visible as well as some foam. Too much water was flowing through system for adequate treatment to occur.

Operator turned off portable work pump and the decreased flow volume. This significantly improved the effectiveness of the dewatering system and discharge started to clear up.

Corrections requested-
- redesign dewatering system/implement controls to keep the flow volume through the settling ponds at continous rate without significant turbid surges to prevent overflow of gravel baffle dams. Submit any dewatering plans to ESC division and notify upon implementation.
- during work, discharge should be monitored regularly to check for issues
- foam captured in middle chamber should not be allowed to discharged
