This project was inspected for compliance with the Stormwater Permit SW7080807 issued to you on August 25, 2008 for the development and operation of a High Density Stormwater Project. The inspection revealed that the project has not yet been completed. As such, you will be rescheduled for an inspection at a later date. This office would like to remind you that you are limited to the impacts proposed in your application and you must comply with all operation and maintenance requirements of this permit. As a reminder, if you change your project you must notify us and you may be required to send us a new application. If the property is sold, the permit must be formally transferred to the new owners/developers by submitting a Name/Ownership Request Form to the DWQ with appropriate documentation. Failure to abide by the conditions and limitations contained in this permit may subject the Permittee to enforcement action by DWQ in accordance with North Carolina General Statue 143-215.6(a) to 143-215.6(c). If your plans to develop the project have been abandoned and/or the property has been sold with the new owners pursuing a new development plan and you no longer require a stormwater permit you may request the permit be rescinded. Please submit a Rescission Request in writing to this Office outlining why the permit is no longer required. The Rescission Request will be considered on its merits, and may or may not be approved.

The feature is labeled as "08-0846 a to 08-0846 b" on the attached maps initialed by me on May22, 2008. The Division of Water Quality (DWQ) has determined that the feature labeled as "08-0846 a to 08-0846 b" on the attached maps and highlighted in red is not subject to the Neuse Buffer Rule. Please note that the stream call for the subject drainage extends 50 feet past the property line as depicted on plan sheet EX-01.

A request for a determination by the Director shall be referred to the Director in writing c/o John Dorney, DWQ Wetlands/401 Unit, 2321 Crabtree Blvd., Raleigh, NC 27604-2260.

You must act within 60 days of the date that you receive this letter. Applicants are hereby notified that the 60-day statutory appeal time does not start until the affected.party (including downstream and adjacent landowners) is notified of this decision.
