IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion,
trash accumulation, vegetative cover, and general condition.
2. Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow
vegetated cover to maintain a maximum height of six inches, and remove trash as needed,
3. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage and repair the structure to approved design
specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth
in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored to the
original design depth without over -excavating. Over -excavating may cause the required water table
separation to be reduced and may compromise the ability of the system to perform as designed. Removed
sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will
adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream, etc.).
A benchmark shall be established in the pretreatment unit. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken. The measuring device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
41ev,TOh 3, 31 �
When the design dept#reads 3: feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
• 5. If the Division determines that the system is failing, the system will immediately be repaired to original
design specifications. If the system cannot be repaired to perform its design function, other stormwater
control devices as allowed by NCAC 2H .1000 must be designed, approved and constructed.
I acknowledge and agree by my signature below that I am responsible for the performance of the five
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.

e. System is located in loamy sand fill material. Fill material from the excavated
marina basin has been laid across the site to build it up for finished grades.
q. System captures and infiltrates the runoff from the first 3.0 inch of rainfall.
Therefore, no bypass structure has been included. A level spreader overflow
structure has been provided at or above the 3.0 inch storm storage elevation which
allows for rainfall in excess of the design storm to sheet flow to wetlands.

Subject: Stormwater Permit Renewal & Ownership Change
Stormwater Management Permit SW7060811
River Dunes Marina & Residential Development
Village Center, Phase l
Pamlico County
Dear Palm Hill Realty, Inc.:
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7060811 for a stormwater treatment system consisting of two
infiltration basins serve the subject development located in Pamlico County expires on
September 20, 2020. This is a reminder that permit renewal applications are due 180
days prior to expiration. We do not have a record of receiving a renewal application.
The permit was originally issued to River Dunes Corporation. It was noted in the
Pamlico County tax records that the property is now owned by River Dunes Land
Holdings, LLC. Permits are not automatically transferred to new owners without the
submittal of an ownership change application and fee. Please submit a completed
permit renewal application along with a $505.00 fee for permit renewal and an
ownership change application. Application forms for renewal and ownership change can
be found on our website at:
https:/./deq.nc.gov/about/div sion:s.luergy-mineral-land-resources/ener_gy-mincr'�-1 Dd--
rul,es stormwater-orggram/post-construction. North Carolina General Statutes and the
Coastal Stormwater rules require that this property be covered under a stormwater
permit. Failure to maintain a permit subjects the owner to assessment of civil penalties.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application forms. You can request a copy by e-mailing me at
