-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, mflow 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 mfiltration 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 a 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 O. 45 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
