Shawn‐
This email serves as a brief update on the investigation associated with the leachate force main at the Mayo Steam
Electric Plant Monofill (PN 7305‐INDUS).
Provisions were made on the Monofill force main line to video the condition. Near Station 32+45 (~55’ upstream of
cleanout 3 located at Station 33+00 – see figure below), separation of a weld on the inner 6” HDPE pipe was
discovered. Attached you can see an image from the camera inspection where the dual containment spacer is
visible. At this time there is no apparent integrity issue with the outer 10” HDPE pipe. The area will be excavated in
order to visually inspect the outer pipe and ultimately repair the primary pipe. Hydro excavation of the area will begin
as soon as weather permits.
If you and your team would like, I can set up a conference call to brief you on the information in this email in addition to
any work that occurs between now and a conference call. You mentioned that Friday might be preferred, just let me
know a suggested time and I will set up a call.
Should any condition change, or additional pertinent information become available prior to us potentially talking on
Friday, I will reach out to you immediately.
Regards‐
Kim
