Re: DWQ#08-1606 - Section 401 Water Quality Certification application for
Crow's Nest Phase III
Dear Ms. Homewood,
In response to your letter to Mr. Sean Long dated November 26, 2008, we offer you the following
information regarding your comments:
1. A revised, complete application has been submitted to Andrew Williams with the US Army
Corps of Engineers for their review.
2. Item XI on Page 12 of the PCN has been answered. I have attached that page for you.
3. We have extended the rip-rap apron beyond the required minimum per NCDENR for
outlet protection to ensure proper re-alignment with the existing channel. A revised
detail has been attached.
4. The rip-rap apron at the inlet has been removed from the plan.
5. The proposed pipe will be constructed away from the existing channel and "in the dry"
therefore, no dewatering of the channel is necessary. I have included the Construction
Sequence from the plans forreference which outlines the construction procedure.
6. Given the nature of the installation of the proposed pipe, there are no temporary impacts
anticipated. Permanent impacts include re-alignment of the channel to the proposed
pipe, removal of the existing 15" RCP and placing permanent fill in the "old" channel bed.
Provisions have been made to ensure constant supervision of this crossing to ensure regulatory
compliance. Copies of the proposed erosion control plans can be provided upon request.
Please contact us if you have any questions, concerns or need additional information or
clarification.
