Re: Section 401 Water Quality Certification application for North Fork Estates
Dear Mr. Hill:
May 4, 2009
DWQ# 09-0071
Guilford County
On April 2, 2009, the North Carolina Division of Water Quality (Division) received your additional'information for the
application for a 401 General Water Quality Certification to impact 146 linear feet of stream and 0.065 acres of wetlands
to install a road crossing for the Ashton Place Facility, near Greensboro NC in Guilford County. Additional information
is still required in order that we may determine your project's compliance with 15A NCAC 2H.0500. The Division will
require this information in order to process your application to impact protected wetlands and/or streams on the subject
property. Therefore, we will place this project on hold as incomplete until we receive this additional information, and if
we do not receive the additional information requested below, we will have to move toward denial of your application as
required by 15A NCAC 2H .0506. Please provide the following information so that we may continue to review your
project.
1. The new site drawings submitted indicate that the toe of the stormwater pond will be constructed just
outside the wetland boundary line. The Division is unclear how construction of the pond slope can be
completed without some impacts (possibly temporary) to the wetland from construction needs and/or
erosion control requirements. Please clarify this issue.
2. As noted in the letter sent February 18, 2009, per the requirements of the General Certification, all work
shall be done "in the dry". Therefore, dewatering methods will be necessary to temporarily dewater the
stream channel during structure installations. Please provide a construction sequence that details the
method of dewatering to be utilized at the site and the sequence of construction events to be
followed to ensure compliance with this condition.
3. As noted in the letter sent February 18, 2009, per the requirements of GC 3705, please enumerate all
temporary impacts (in addition to permanent impacts already indicated) to the stream channel and any
wetland areas. Temporary impacts include areas of disturbance necessary for proper pipe installation,
proper dewatering, as well as any impacts from temporary erosion control measures or fill stabilization.
Please note that temporary impacts should be minimized to the maximum extent practical.

4. Per the requirements of GC 3705, pipes and culverts must be buried below the stream bed elevation.
The pipe profile submitted does not indicate pipe burial. Please modify this design and drawings or
submit a request for a waiver with justification for installing the pipe at stream grade elevations.
Please respond in writing within 30 calendar days of the date of this letter by sending a copy of this information to Sue
Homewood at the address on this letterhead, and a copy to Ian McMillan N. C. Division of Water Quality, Wetlands/401
Certification Unit, 1650 Mail Service Center, Raleigh, NC 27699-1650. If you will not be able to provide the requested
information within that timeframe, please provide written confirmation that you intend to provide the requested
information, and include a specific timetable delineating when the requested materials will be provided. If we do not hear
from you in 30 calendar days, we will assume that you no longer want to pursue this project and we will consider the
project as returned.
This letter only addresses the application review and does not authorize any impacts to wetlands, waters or protected
buffers. Please be aware that any impacts requested within your application are not authorized (at this time) by the
Division. If you have any questions, please contact me at 336-771-4964 or [e-mail].
