REQUEST FOR MORE INFORMATION
Dear Mr. Alvis:
On June 23, 2008, the Express Review Program of the Division of Water Quality (DWQ) received your
additional information for the above referenced project. The DWQ has determined that your application
still requires the additional information outlined below in order to continue the review process and
prevent denial of your application as required by 15A NCAC 2H.0506:
Additional Information Requested
Diffuse Flow:
a. The outflow calculations for FES IA indicate a pipe outlet velocity of 9.78 fps. It is agreed
that the outlet is sufficiently protected but the velocity of flow is likely to be erosive even
after leaving the dissipater pads. We recommend that a further slowing down of the water is
required by installing a plunge pool of P minimum depth and sufficient length, width and
slope at the end of the pipe instead of a flat dissipater pad.
Please respond within five (5) days of the date of this letter by sending two (2) copies of the above
information in writing. The Express Review Program is a process that requires all parties to participate in a
timely manner.
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 DWQ.
Please contact Joseph Gyamfi or Lia Myott Gilleski at 919-733-1786 if you have any questions regarding
or would like to set up a meeting to discuss this matter.
Sincerely,
4- M - C
