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. 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.

Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention 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 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 (see diagram below). 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 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 2.25 feet in the forebay, the sediment shall be removed.

A heat sensor thermostat and overload shall be attached to the top end of the motor windings and
shall be wired in series with the windings to stop the motor if the motor winding temperature reaches
266°F. The overload thermostat shall reset automatically when the motor cools to a safe operating
temperature. Three phase motors shall be protected by 3 leg overload relay in control box. Overload
shall be of the quick trip ambient compensated type and shall have manual reset button.
POWER CORD - The motor power cord shall be SJOW or SOOW. The cable jacket shall be sealed at
the motor entrance by means of a rubber compression washer and compression nut. A heat shrink
tube filled with epoxy shall seal' the outer cable jacket and the individual leads to prevent water from
entering the motor housing.
SHAFT SEAL - The motor shall be protected by a rotating mechanical shaft seal. The seal shall have
carbon and ceramic seal faces lapped to a tolerance of one light band. Metal parts and springs for
seals shall be 300 series stainless steel.

QUMP IMPELLER - The pump impeller shall be of the two vane enclosed type. The impeller shall be
constructed of engineered thermoplastic or optional bronze. A stainless steel wear ring shall be r
molded into the neck of the plastic impeller to provide a sealing surface. a replaceable Buna-N seal-
ing cup shall effect a seal between the volute and impeller in order to maintain high efficiency and.
prevent recirculation. The impeller shall be threaded onto the 416 stainless steep pump/motor shaft.
PUMP AND MOTOR CASINGS - All castings shall be of high tensile strength Class 30 gray cast iron.
Castings shall be treated with phosphate and chromate rinse and painted with a high quality air dry
alkyd enamel.
