On April 12, 2010, and June 16, 2010, the DWQ received additional information from you, however, the DWQ has determined that your application remains incomplete and/or provided inaccurate information as discussed below. The DWQ will require additional information in order to process your application to impact protected wetlands and/or streams on the subject property. Therefore, unless we receive five copies of the additional information requested below, we will place this project on hold as incomplete until we receive this additional information. 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: 1. A Wet Detention Pond does not provide an adequate level of total nitrogen removal (25%) to be used in place of a level spreader (a minimum of 30% total nitrogen removal is required). At Outlets 1 and 4/5, please replace the proposed wet detention ponds with stormwater wetlands. A stormwater wetland will work in an area with a high SHWT and also provide sufficient total nitrogen removal to be used in place of a level spreader (40%). 2. For the level spreader designs, please address the following issues: a. Per Item 2 of the Required Items Checklist, please provide custom plan details at a 1" = 30' scale or large with 1' topographic lines, showing proposed topo and its connection to existing topo. On these details, please include specific details on the proposed flow splitting devices with correct swale dimensions, invert elevations, etc. 401 Oversight/Express Review Permitting Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 Location: 2321 Crabtree Blvd., Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-17861 FAX: 919-733-6893 Internet: http://portal.ncdenr.org/web/wgtws An Equal Opportunity 1 Affirmative Action Employer Franklin County Economic Development Commission Page 2 of 2 June 28, 2010 b.

For level spreader 7, please show 1' contours downslope of the level lip. Please explain the choice of discharge location for the bypass channel (for example, it could be an existing natural draw). 3. The Operation and Maintenance Agreements must be signed and notarized.

If we do not receive this requested information within 30 calendar days of the date of this letter, your project will be withdrawn and you will need to reapply with a new application and a new fee.
