The 401 certification requires that a stormwater management plan (SMP) be developed and approved for
each phase of this project prior to any land disturbance and that no buildings shall be occupied until the
stormwater management plan is constructed and operational for that phase. It further requires that all
SMP's be designed in compliance with the NC DENR Stormwater BMP Manual in effect at the time of
submittal. According to these requirements, a stormwater management plan for POD 10 Phase One was
received by this Division on October 30, 2015 and reviewed for compliance.
The DWR approves the SMP for POD One as meeting the 401 Water Quality Certification conditions.
This approval is for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new SMP. This approval requires that
you follow the conditions listed in the Water Quality Certification for the project and the following
