Charles,
The MRO is in agreement with the rescission for NCG510207.
The permittee has disconnected the system and the system no longer has capacity to discharge to the outfall. The
permittee has also submitted an NOI for the construction of a AS/VE deemed permitted system to continue treatment of
the remaining plume constituents.
Best Regards,
Ed

Hello Maribeth,
The disconnection of power to the system is good. However, have the avenues of flow to the outfalls been sealed so no
flow can travel through the outfall channel? Also, all associated wells need to remain open so they can be utilized for
the AS/SVE system.
Regards,
Ed

Hello Maribeth,
The old treatment system will need to be adequately disconnected so that discharge from the old pump and treat
system can no longer occur. Please notify our office once the old system has been disconnected and email photos of the
disconnected treatment system.
Once we receive the documentation of the disconnection, we can recommend the rescission of the permit.

Hello Ms. Hughes,
Please submit a Notice of Intent to Construct (NOI) request for the deemed permitted Bio-Sparge system to Mr. Mike
Rogers in the UIC permitting office of the Division of Water Resources for the construction of the Bio-Sparge system.
These permits are issued from our Central office in Raleigh. Mike can be contacted at ' [e-mail].
Please have our consultant submit the NOI including the number of well points and a diagram of the treatment system.
Once we receive the approved permit for the Bio-Sparge system, I will advise Charles Weaver that we will agree to
rescind the current Pump and Treat permit.
Please keep our office informed if Colonial is planning to amend the construction.

Mr. Watson —
In late 2018 Colonial prepared a CAPA for incident #6162 and submitted it to the Department. That CAPA was approved
on 11/7/18.
However, prior to implementation of the CAPA, there was an incident on 12/31/2018 at the Charlotte Delivery facility
(the release associated with Tank Line 762). It was decided, in conjunction with the UST group of NCDENR, to revisit the
approved system defined within the CAPA to determine if it would address/impact both the original remediation effort
being performed by the existing pump -and -treat (P&T) system and the newer release. It was agreed that while the
assessment for the newer release was ongoing, Colonial would continue to operate the existing P&T system until the
approved bio-sparge system within the CAPA was implemented.
There have been multiple issues over the last few months with the existing P&T system. After significant efforts, it has
proven to be unfeasible to repair the existing P&T system. Therefore, Colonial, with your approval, will be moving
forward with decommissioning the existing P&T system and implementing the CAPA described system (biosparge). It is
anticipated that the applications for the bio-sparge system wells will be submitted to NCDENR by 4/1/23 and, pending
approval, the new system is expected to be functional by the end of 2023.
Please let me know if you have any comments or questions.

Ms. Hughes — in order to rescind NCG510207, you will need t contact Mr. Ed Watson of the NC DEQ Mooresville Regional
Office [copied on this message] and explain how the existing remediation system is to be replaced. One the MRO is
satisfied with the information, I will receive approval to rescind NCG510207.

Hello Charles.
No. We have not received information from the permittee regarding alternative GW treatment for this facility. If you
have received any documentation referencing this system, can you forward it to me, as I have not seen it.
Thanks
