Subject: State Stormwater Management Permit No. SW8 931204
Ocean Harbour Estates
High Density Residential Infiltration Trench Project
Brunswick County
Dear Mr. Johnston:
The Wilmington Regional Office received a complete modified Stormwater Management Permit Application for the
subject project on November 6, 2012. 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 21-1.1000, effective September 1,
1995. We are forwarding Permit No. SW8 931204, dated November 2, 2012, for the construction, operation, and
maintenance of the subject project. The plans previously approved on May 31, 2002 and renewed on January 4,
2012 remain in effect.
Modifications Include: Lot 4 of Ocean Harbour Estates has been issued individual State Stormwater permit
SW8121008 so that that lot can increase its impervious area beyond the amount allocated to it by SW8
931204. That permit, SW8121008, will drain partially offsite to this permit, SW8 931204, and will be treated
partially onsite with its own infiltration trench which will be maintained by the SW8121008 permittee. This
permit, SW8 931204, has therefore had a decrease in drainage area because some of the previous
drainage area is now being treated by the infiltration trench permitted under SW8121008. The total
impervious area and the impervious area per lot for this permit, SW8 931204, have not been changed. No
other changes have been made to SW8 931204. The plans previously approved on May 31, 2002 and
renewed on January 4, 2012, in accordance with the regulations set forth in Title 15A NCAC 21-11.1000
effective September 1,1995, remain in full force and effect.
On August 5, 2009, the Governor signed Session Law 2009406. This law impacts any development approval issued
by the Division of Water Quality under Article 21 of Chapter 143 of the General Statutes, which is current and valid at
any point between January 1, 2008, and December 31, 2010. The law extends the effective period of any stormwater
permit that is set to expire during this time frame to three (3) years from its current expiration date. On August 2,
2010, the Governor signed Session Law 2010-177 which grants an extra year for a total of four (4) years extension.
Accordingly, Stormwater Permit # SW8 931204, which was set to expire on May 31, 2022, is now in effect until May
31, 2026. This permit shall be effective from the date of issuance until May 31, 2026, 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 by filing a petition with the Office of Administrative Hearings (OAH). The petition must conform
to Chapter 150B of the North Carolina General Statutes, and must be filed with the OAH within thirty (30) days of
receipt of this permit. A petition is considered filed when it is received in the Office of Administrative Hearings during
normal office hours. The OAH accepts filings Monday through Friday between the hours of 8:00 a.m. and 5:00 p.m.,
except for official state holidays. The petition may be filed by facsimile (fax) or electronic mail by an attached file

Infiltration Trench Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— The drainage area of the infiltration trench will be carefully managed to reduce
the sediment load to the sand filter.
— The water level in the monitoring wells will be recorded once a month and after
every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
The infiltration trench will be inspected once a quarter and within 24 hours after every
storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of
operation and maintenance will be kept in a known set location and will be available
upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

u. A benchmark for checking sediment accumulation is provided.
IV. UNDERGROUND INFILTRATION TRENCH OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly inspect the bypass/overflow structure for
blockage and deterioration and the infiltration system for erosion, trash accumulation, grass cover, and general
condition.
2. Repair eroded areas immediately, reseed as necessary to maintain adequate vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash and blockages as needed to maintain
system performance.
3. Remove accumulated sediment annually or when depth is reduced to 75% of the original -design depth. Restore
depth to 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.
4. The water level in any monitoring wells will be recorded after a 1 inch rainfall event and at least once a month.
Chronic high water table elevations (within 1 foot of the bottom of the system for a period of three months)
shall be reported to DWQ immediately.
5. If DWQ determines that the system is failing, the system will immediately be repaired or replaced 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.
6. Remove accumulated sediment from the infiltration system annually or when depth -in the 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 infiltration system. 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 depth at the benchmark reads , the accumulated sediment shall be removed
from the system.

6. Remove accumulated sediment from the infiltration system annually or when depth in the 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 infiltration system. 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 depth at the benchmark reads , the accumulated sediment shall be removed
from the system.
