Dear Mr. Hatchell:
The Washington Regional Office received a completed Stormwater Application for the subject project on
June 11, 2007. Staff review of the plans and specifications has determined that the project, as proposed, will comply
with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000. We are forwarding Permit No. SW7060117
dated June 27, 2007 to Oasis, LLC for the construction and operation of an infiltration basin to serve the Oasis Hotel
developm wed at 7710 and 7722 South Virginia Dare Trail Head in Nags Head, NC.
This permit shall be effective from the date of issuance until June 27, 2017, shall void Permit No. SW7060117
dated March 7, 2007 and shall be subject to the conditions and limitations as specified therein. Please pay special
attention to the Operation and Maintenance requirements in this permit. Failure to establish an adequate system for
operation and maintenance of the stormwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit. This
request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes,

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
I . 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 the 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.
When the design depth reads _1.50_ 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.
1 acknowledge and agree by my signature below that I am responsible for the performance of the five maintenance procedures
listed above. 1 agree to notify DWQ of any problems with the system or prior to any changes to the system or responsible party.

Applicants Initials
or a.
System is located 50 feet from class SA waters and 30, feet from other surface waters.
n ,� b.
System is located at least 100 feet from water supply wells.
�T//W c.
Bottom of system is at least 2 feet above the seasonal high water table.
h. d.
Bottom of the system is 3 feet above any bedrock or impervious soil horizon.
�� e.
System is not sited on or in fill material or DWQ approval has been obtained.
0. N f
System is located in a recorded drainage easement for the purposes of operation and
maintenance and has recorded access easements to the nearest public right-of-way.
P g. Drainage area for the device is less than 5 acres.
h. Soils have a minimum hydraulic conductivity of 0.52 inches per hour and soils report is
attached.
0. (/ i. System captures and infiltrates the runoff from the first 1.0 inch of rainfall (1.5 inch event for
areas draining to SA waters ). Design volume and infiltration calculations attached.
lcc _/ j. System is sized to take into account the runoff at the ultimate built -out potential from all
surfaces draining to the system, including any off -site drainage. Calculations attached.
k. All side slopes stabilized with vegetated cover are no steeper than 3:1 (H:V).
1. A pretreatment device such as a catch basin, grease trap, filter strip, grassed swale or
sediment trap is provided.
b " in. Bottom of the device is covered with a layer of clean sand to an average depth of 4 inches
or dense vegetative cover is provided.
D, ii n. Vegetated filter is provided for overflow and detail is shown on plans (Required minimum
1 length is 50 feet for SA waters, 30 feet for other waters).

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 the 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.
When the design depth reads _1.50_ 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 211 .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.
