Dear Mr. Stancil:
John E. Skvada, III
Secretary
Effective August 1, 2013 the State Stormwater program has been transferred from the Division of Water Quality (DWQ) to
the Division of Energy, Mineral and Land Resources (DEMLR). All previous references to DWQ will remain in older
stormwater permits issued prior to August 1, 2013 until they are modified. Please note that any updated pages or
addendums to the permit will now reference DEMLR as the Division responsible for issuance of the permit.
The Wilmington Regional Office received a complete, modified State Stormwater Management Permit Application for the
subject project on November 14, 2014. 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 January 1,1988.
We are forwarding Permit No. SW8 950215 dated November 25, 2014, for the construction, operation and maintenance of
the BMP's and built -upon area associated with the subject project. This permit shall be effective from the date of issuance
until rescinded and shall be subject to the conditions and limitations as specified therein.
The following requirements are continued from the attached Certification of Compliance originally issued on April 24,1995
and transferred to the HOA on February 6, 2013:
1. Staff review of the project plans and specifications, including the statement of intent has determined that the
stormwater control system as proposed for Beacon Woods Subdivision will comply with the Stormwater
Regulations set forth in Title 15A NCAC 21-1.1003(i), effective January 1,1988. This Certification is to restrict the
built -upon area for each of the 112 lots, as shown on the approved plan.
2. Any modification of the plans submitted to and approved by this Office or further development of this site
regardless of the fact that the modification may be less than 1 acre, will require an additional Stormwater
Submittal/Modification and approval prior to initiation of construction. Modifications include but are not limited to;
project name changes, transfer of ownership, redesign of built -upon surfaces, addition of built -upon surfaces,
redesign or further subdivision of the project area.
This Cerfification shall be effective from the date of issuance until rescinded. The project shall be constructed and
maintained in accordance with the plans and specifications approved by the Wilmington Regional Office, This
Certification does not supersede any other permit or approval. The developer is responsible for obtaining any and
all permits and approvals necessary for the development of this project. This could include the Division of Coastal
Management under CAMA requirements, the Division of Water Resources Wetland 401 Water Quality
Certification and/or a Dredge and Fill Permit and/or a Sewer Extension/Collection Permit, U.S. Army Corps of
Engineers 404 Wetland Permit, NPDES Stormwater Permit if disturbing five acres or more, local County or Town
Agency permits under their local ordinances, or others that may be required.
4. A professional engineer must certify. that the stormwater system has been installed in accordance with the
approved plans and specifications upon completion of construction. The attached certification should be received
by this Office within 30 days of completion of construction.
5. The detention pond must be constructed in its entirety, operational for its intended use, and permanently
vegetated prior to the construction of any impervious surfaces proposed as a part of the project, except roads.

The following modifications are included and covered by this permit:
1. All lots shall be limited to 4,000 square feet of impervious area per lot with the exception of Lot 77 which is
approved for 5,100sf of impervious area. The runoff from the impervious area specified in the summaries for
Ponds 1 and 2 will be treated to achieve 90% reduction in Total Suspended Solids. Two-thirds of each lot must be
graded to drain into the street.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an
adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The written petition must
conform to Chapter 150B of the North Carolina General Statutes, and must be filed with the OAH within thirty (30) days of

Footnotes:
1 When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 The requirement for a vegetative filter may be waived if the wet detention basin is designed to meet 90% TSS removal.
3 The legally responsible party should not be a homeowners association unless more than 50% of the lots have been sold and a
resident of the subdivision has been named the president.
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, forebay, non-integrated pretreatment
systems (pretreatment other than forebays),, and the vegetated filter if one is provided.
This system (check one) ❑ does ❑ does not incorporate a vegetated filter.
This system (check one) ❑ does ❑ does not incorporate non-integrated pretreatment.
Maintenance activities shall be performs as follows:
1- After every significant runoff producing rainfall event and at least monthly:
Form SWU-102 Rev 1/August 1998 Page 2 of 3

a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation, grass
cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth. 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
wet detention basin or stream, etc.).
The original design depth is: (p
The sediment removal benchmark dep is: 4.13
5. Remove cattails and other indigenous wetland plants when they cover 75% of the basin surface. These
plants shall be encouraged to grow along the basin perimeter.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through
the emergency drain shall be minimized to the maximum extent practical.
7. All components of the wet detention basin system shall be maintained in good working order.
I acknowledge and agree by my signature below that I am responsible for the performance of the above
maintenance procedures. I agree to notify DWQ of any problems with the system or changes in the name of the
project, responsible party, or address.

Wet Detention Basin 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.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
❑ does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
- Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
- No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
- Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
- If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
- Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month 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 should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
