REQUEST FOR MORE INFORMATION
Dear Mr. Lafrenaye:
On August 3, 2011, the Division of Water Quality (DWQ) received your application dated August 3, 2011 to fill or
otherwise impact 32 linear feet of intermittent stream channel (permanent impacts), 4,353 square feet of Zone 1
Neuse River basin protected riparian buffer, and 3,931 square feet of Zone 2 Neuse basin protected riparian buffer
to construct a UNC Hosptial Campus in Hillsborough. The DWQ has determined that your application was
incomplete and/or provided inaccurate information as discussed below. The DWQ will require additional
information in order to process your application to impact protected streams and buffers on the subject property.
This project is on hold and incomplete until we receive the additional information requested below. If we do not
receive the requested information, your project will be formally returned as incomplete. Please provide the
following information so that we may continue to review your project.
Additional Information Requested:
DWQ does allow new stormwater conveyances to directly discharge into a stream without
30% nitrogen removal and attenuated flow through the riparian buffer per [15A NCAC 02B
.0233(6)]. In addition, DWQ does not allow concentrated flow from manmade conveyances
through the buffer.
a. Please provide a diffuse flow plan for the site.
b. You must show that this site meets diffuse flow requirements with a level spreader or
other BMP per Chapter 8 of the BMP Manual (see
http://portal.ncdenr.org/web/wq/ws/su/bmp-manual).
