Subject: [URL Verdict: Neutral][Non-DoD Source] DWR#20220746: Colonial Pipeline Company, Line 24 Exposure,
Chatham County - POST CONSTRUCTION SITE VISIT 1/18/2023
Importance: High
Good Afternoon,
Thank you again for taking the time to meet with us for the post -construction site visit today for DWR# 20220746 - Line
24 Exposure 401 certification.
Per the onsite conversations and findings today, this site is considered out of compliance with the parameters listed in
the issued 401.
DWR is requiring a response to this notification of non-compliance that addresses the following:

1. Riprap located on both the upstream and downstream sides of the revetment mat has been placed in a manner
that is causing the stream to flow beneath the material at normal flow conditions. All riprap should be keyed
into the stream channel and banks, as indicated in the plans submitted along with the application and approved
as part of the issued 401, so that the stream can flow overtop of the material without significant
interference. Please respond to this email with a plan for how this will be addressed including a detailed
description and updated impact maps for approval.
2. As part of your plans, please include any temporary impacts that will occur during the construction process
(pump arounds, etc.).
3. As part of your plans, please include an anticipated date that construction will begin and end.
Please provide a response and remediation plans within 30 days of this notification. If you have any questions, please
let me know.
Thank you,

Thank you for the notification, Mackenzie. I will be leaving DWR, so I have CC'ed Sue Homewood and Zach Thomas. I
believe both are tied up in a training course this week, but may wish to schedule a site visit at a later date after
installation.
Please contact Zach Thomas in the future as he will be the 401 Reviewer for the Raleigh Regional Office.
I've also attached a copy of the revised letter. Thank you for catching that typo.
Have a wonderful day,
