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 in the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
11. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: 15 A NCAC 2H .1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below. If a requirement has not been met, attach justification.
Is
a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
b. The forebay volume is approximately equal to 20% of the basin volume.
c. The temporary pool controls runoff from the design storm event.
d. The temporary pool draws down in 2 to 5 days.
e. If required, a 30-foot vegetative filter is provided at the outlet (include non -erosive flow
calculations)
f. The basin length to width ratio is greater than 3:1.
g. The basin side slopes above the permanent pool are no steeper than 3:1.
h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
i. Vegetative cover above the permanent pool elevation is specified.
j. A trash rack or similar device is provided for both the overflow and orifice.
k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
1. If the basin is used for sediment and erosion control during construction, clean out of the
basin is specified prior to use as a wet detention basin.
% m. A mechanism is specified which will drain the basin for maintenance or an emergency.
111. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
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) 0 does O does not inco porate a vegetated filter at the outlet.
This system (check one) O does Q does not incorporate pretreatment other than a forebay.
Form S WU-102 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
l . After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated 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 as designed.
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 -heeded.'
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quartefly 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 (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 3.0 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3.0 feet in the forebay, the sediment shall be removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
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.

Permit No. SW7060118
Beaufort County
Dear Beaufort County Schools:
On September 23, 2009, Amy Adams and Wayne Bryant of the Washington Regional Office of the .Division of Water Quality
(DWQ) inspected Bath Elementary School in Beaufort County to determine compliance with Stormwater Management Permit
Number SW70601 18 issued on March 1, 2006, DWQ file review and site inspection revealed that the site is compliant with the
tenns and conditions of this permit Please find a copy of the completed form entitled "Stormwater Inspection Report" attached
to this letter. As a result of the site inspection and file review, there were no violations found
There were however some areas of maintenance issues that need addressing or monitoring. A copy of a Wet Pond Operation
and Maintenance agreement is provided for your use in maintaining your stormwater pond.
Please be advised that you are required to comply with the terms, conditions and limitations of your Stonnwater Management
Permit under Title 15A North Carolina Administrative Code 2H .1003 and North Carolina General Statute 143-214.7, including
operation and maintenance of your permitted Stormwater system. Please be advised that violations of your Stormwater
Management Permit may be subject to the assessment of civil penalties of up to $25,000 per day per violation.
Thank you for your cooperation and conscientious effort to help safeguard the waters of the State. If you should have any
questions regarding these matters, please feel free to contact me at [phone].

State Stormwater Inspection Report
l . Some minor areas of bare soil were noted around the top of the pond slopes. Please make sure that you are not mowing too low
causing the grass to die off. Re -seed as necessary to maintain a healthy grass cover.
2. A small area of erosion was noted adjacent to the inlet pipe. Please continue to monitor and take corrective actions as necessary.
3. The vegetated shelf was void of any vegetation. Please continue to work on establishing the plants for the vegetated shelf.
4. The outlet structure does not include any sort of trash rack for the overflow weir and is allowing trash to enter your outlet pipe.
This may cause clogging within the pipe. Please install a trash rack device on the overflow side of the outlet structure.
5. The drawdown pipe has algae growth around the outside of the pipe. Please remember to monitor this and clean the orifice of
any obstructions.
