IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. 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, re -seed 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 S.. 0 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 2H .1000 must be designed, approved and constructed.
I 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.

I1I. 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 that 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. Attach justification if a requirement has not been met.
Applicants Initials
3JA a. System is located 50 feet from class SA waters and 30 feet from other surface waters.
3» b. System is located at least 100 feet from water supply wells.
IDth C. Bottom of system is at least 2 feet above the seasonal high water table.
I.& d. Bottom of the system is 3 feet above any bedrock or impervious soil horizon.
AAA e. System is jwrsited on or in fill material or DWQ approval has been obtained.
f.
System is located in a recorded drainage easement for the purposes of operation and
maintenance and has recorded access easements to the nearest public right-of-way.
JJlri g.
Drainage area for the device is less than -5 acres.
.�J Pr h.
SoiIs have a minimum hydraulic conductivity of 0.52 inches per hour and soils report is
attached.
i.
System captures and infiltrates the runoff from the first 1.0 inch of rainfall (1.5 inch event
for areas draining to SA waters ). Design volume and 'infiltiation calculations attached.
j.
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.
J� k.
All side slopes stabilized with vegetated cover are no steeper than 3:1 (H:V)_
ash 1. A pretreatment device such as a catch basin, grease trap, filter strip, grassed swale or
sediment trap is provided.
,1 a'W m. 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
length is 50 feet for SA waters, 30 feet for other waters). .
NIk o. Flow distribution mechanism within the basin is provided.
J 1� P. A benchmark is provided to determine the sediment accumulation in the pretreatment
device.
33pt q. Runoff in excess of the design volume bypasses off-line systems (bypass detail provided).
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 draw -down 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
1. 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, re -seed 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 Co.7-6' 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 2H .1000 must be designed, approved and constructed.
I 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.
