IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
After every runolTproducing rainfall event and at least montlily inspect the infiltration system for erosion, trash
accumulation, vegetative cover, and general condition.
Repair eroded areas immediately, reseed as necessary to maintain adequate vegetative cover, mow vegetated
cover to maintain a maximum height of'six inches, and remove trash as needed.
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. Rentove accumulated sediment from the pretreatment system and infiltration basin annually or when 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 strearn, etc.).
A benchmark shall be established in the pretreatment unit. 'file 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.
N
When the design depth reads 7r feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
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 A 000 must be designed, approved and constructed,
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.

areas draining to SA waters ). Design volume and infiltration calculations attached.
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.
�w k. All side slopes stabilized with vegetated cover are no steeper than 3:1 (H:V).
Ay/k 1. A pretreatment device such as a catch basin, grease trap, filter strip, grassed Swale or sediment
trap is provided.
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.
n. Vegetated filter is provided for overflow and detail is shown on plans (Required minimum
'n�
length is 50 feet for SA waters, 30 feet for other waters).
/0ky o. 'Flow distribution mechanism within the basin is provided.
thA)K p. A benchmark is provided to determine the sediment accumulation in the pretreatment device.
MOjV, q, Runoff in excess of the design volume bypasses off-line systems (bypass detail provided).
MAI r. System is designed to draw down the design storage volume to the proposed bottom elevation
under seasonal high water conditions within five days. A soils report and all pertinent
drawdown calculations are attached.
s. Plans ensure that the installed system will meet design specifications (constructed or restored)
upon initial operation once the project is complete and the entire drainage area is stabilized.

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, reseed 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 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 IZ 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 21-1 A 000 must be designed, approved and constructed.
I acknowledge and agree by my signature below that I am responsible for the performance ofthe 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.
