Describe the attachments or
comments:
The applicant is currently working on this project and has run into an issue with regard to the jack and bore
method proposed under the stream. The streambed is at a greater depth than surveyed requiring a greater
angle for the jack and bore and also they have encountered bedrock at depth that impacts the jack and bore
method. They are proposing to reduce the casing pipe from 24-inches to 12-inches but request to temporarily
disturb the stream/streambed with an open cut. They are anticipating an approximate width of temporary
disturbance of 10 feet over a 5 -foot-wide section of streambed. They will be utilizing a pump around to
maintain the stream hydrology with other soil erosion measure already in place to avoid/minimize
sedimentation downstream. Attached to this request are sheets C110 — Sanitary Sewer Plan and Profile,
EC103 — Erosion Control Stream Crossing and EC202 - Erosion Control Details.
The applicant is requesting a quick turnaround for approval as the contractor is currently onsite working and are
also working against a deadline for buildings to be ready for tenants moving from the Alamance County
Regional Hospital.

The purpose of this letter is to request a modification to a previously approved 401 Water Quality
Certification for the above referenced project. The applicant is currently working on this project
and has run into an issue with regard to the jack and bore method proposed under the stream.
The streambed is at a greater depth than surveyed requiring a greater angle for the jack and bore
and also they have encountered bedrock at depth that impacts the jack and bore method. They
are proposing to reduce the casing pipe from 24-inches to 12-inches but request to temporarily
disturb the stream/streambed with an open cut. They are anticipating an approximate width of
temporary disturbance of 10 feet over a 5 -foot-wide section of streambed. They will be utilizing a
pump around to maintain the stream hydrology with other soil erosion measure already in place
to avoid/minimize sedimentation downstream. Attached to this request are sheets C110 —
Sanitary Sewer Plan and Profile, EC103 — Erosion Control Stream Crossing and EC202 - Erosion
Control Details.
The applicant is requesting a quick turnaround for approval as the contractor is currently onsite
working and are also working against a deadline for buildings to be ready for tenants moving from
the Alamance County Regional Hospital.
ECS looks forward to your attention to this request. Please contact me at [phone] or
