Please give a brief project description below.

Based on our email exchange with Ms. Sue Homewood and
conversation with Mr. Alan Johnson the North Carolina Department of
Environmental Quality (DEQ; Appendix A), Corblu Ecology Group,
LLC (Corblu) has been advised to submit an "After -the -Fact" pre -
construction notification (PCN), 401 Water Quality Certification
(General Certification 4132), for disturbances to Dixon Branch and
the abutting emergent wetland area on behalf of our client, Colonial
Pipeline Company (CPC) for pipeline preventative maintenance
activities. Corblu received notification of an erosional issue within
Dixon Branch and the abutting wetland which required CPC to
respond immediately to maintain the exsting and serviceable
pipeline, known as Line 1. The performed maintenance activity,
referred to as Line 1 Washout (35.353412,-80.860634), is located in
Mecklenburg County, North Carolina and was accessed through
CPC's right-of-way (ROW) from 1-485. The total disturbance to the
streambed (Dixon Branch) exceeded 40 linear feet which requires
401 Water Quality Certification from the DEQ.
Please give a couple of dates you are available for a meeting.
