All,

I apologize for the delay in responding. I have spoken with Jerry, Donny, and Phil this morning regarding the two losses.

In addition to the recommendations below, ensure maintenance needs and repairs are accurately and thoroughly
documented on the NPDES records including completion date of repairs. Groundcover needs should also be
documented on the NPDES records.

Permit Site #4 Recommendations:
-EC measures should be cleaned out/repaired to good working order and material should be retrieved from the wetland
area per guidance from Jerry/Della. It is my understanding that this is underway.
-Efforts should be made to pursue groundcover to every extent feasible and within the required NCG01 timeframes.
-Efforts should be made to incorporate PAM per plans and wherever feasible to reduce turbidity.

Borrow Site #3 Recommendations: It is my understanding that all of the below recommendations are currently
underway.
-Recommend clean out and repair of EC measures to good working order and material is retrieved per guidance from
Jerry/Della.
-Efforts should be made to reconstruct the TSD at this location with substantial enough berm to prevent
overtopping/failure in the future.
-Ensure TRSC-As are re-installed per plans and per spec. Emphasis should be made on ensuring the TRSC-As are
constructed with a defined weir section to prevent failure of the TSD/berm.
-Erodible area throughout the perimeter of the borrow site should be stabilized within the required NCG01 timeframes
including the TSDs/TDs.

If you have any questions please feel free to call.

Josh,

I have informed DWR of the loss and either Della or I will visit the site on Monday.

Jerry,

We discovered 2 silt losses during today’s walkthrough. Photos are attached for each site.

At Permitted Site 4, silt made it through the stone outlet and into the JS. There were no obvious device failures or
blowouts. Estimated Silt Loss, 0.5 CY.

At Borrow Pit 3, a stone outlet was blown out, resulting in silt and stone making it to the JS. Estimated Silt Loss, 6 CY.

Devices will be repaired, and we will await your recommendations before doing anything in the permitted sites.
