REQUEST FOR MORE INFORMATION
Dear Mr. Pate:
On December 4, 2007, the Division of Water Quality (DWQ) received your application dated November
16, 2007 to impact 509 square feet (ft2) of Zone 1 of the protected riparian buffers to construct the
proposed emergency detention structure and associated utility lines at the subject property. 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 wetland, streams and/or buffers on the subject property. Therefore, unless we receive the
additional information requested below, we will have to move toward denial of your application as
required by 15A NCAC 2H .0506 and 2B .0243(8) and will place this project on hold as incomplete until
we receive this additional information. Please provide the following information so that we may continue
to review your project.
Additional Information Requested:
1. Impact Justification (Avoidance and Minimization)
This Office believes that impacts to Zone 1 of the protected riparian buffer can be avoided or
minimized for the emergency detention structure. Please reconfigure your plans to reflect this
change.
2. Buffer Impacts
Please quantify the square footage of impacts for the emergency detention structure in Zone 2 of the
protected riparian buffer.
3. Variance
The proposed emergency detention structure will require a variance from the Catawba Buffer Rules
(15A NCAC 2B.0243). You are required to fill out and submit three copies of a Variance
application to DWQ.
