Art,
Thank you for the update and the report. Given the size of these basins and large amounts of muddy material there, I'm
actually a bit surprised more material didn't escape out. I'm glad repairs were done promptly, too.
You said the sediment would be dug out by hand....any remaining thin layers can be covered with native seed mix and
likely help keep the majority of areas outside the project area stable.
Considering the size of the basins and steepness of the slopes, anything else than DOT can do to "beef up" the BMPs
would be appreciated, such as mulching or covering the berm with fabric, or adding a second line of sediment fence as a
backup on the sides facing the tributary. I'm mostly throwing ideas out to consider that I've seen in other projects.
With possible rains over the few days, if the Division can give James and me a followup update in a week or so on how
things look and how things are holding up here, that would be great, and we can chalk this up as a one-time issue.
Thanks. Have a good afternoon,

Art,

Please see the attached photos regarding silt loss on R-3421A. This information with be in regards to Waste Site 3. This is
the area that silt went off site around 4-8 CY of silt is estimated to have gone off site and entered a JS. Clean up is
underway in these areas once all areas have been sufficiently cleaned I will send follow up pictures. All production work
on the job site has been shut down until erosion control measures and silt is cleaned. A couple of the last photos here
show clean up already completed in some areas around waste site 3.

Art,
Thank you for the notice. I'll look forward to the detailed report from the assistant engineer.
Be sure that it includes photos of the basin and tributary to confirm repair & clean up. Also a markup of the
plan sheet for the site showing the site location as it relates to the stream for our records. At that time I can
assess if need be to do site inspection.
Thanks,
Rob Ridings

Subject: Sediment loss R-3421A

Mr. Lastinger,
Mr. Ridings,

As required, I am reporting a sediment loss on R-3421A in Richmond County. The loss came from the failure of
a large sediment basin that was overwhelmed by a rain event that was reported to have dropped 3 inches of
rain on the site in about 30-40 minuets. The project inspectors only discovered the loss after they were able to
access the site after it had dried enough for them to enter it. I am not sure when the event took place The
estimated material loss is around 8 cubic yards. I visited the site yesterday and the contractor had already
started the cleanup process. They have also started repairs to the erosion control devices that were damaged.

Fortunately the sediment loss was mostly confined to a small tributary through a wooded area and did not
reach the larger creeks. The contractor is removing the material from the wooded area by hand.

The Assistant Resident is putting together a more detailed report that I will forward to you when I receive it.

Please let me know if you need additional information

Thanks,

Art King
