Dear Mr. Golasa:
The Washington Regional Office received a complete Stormwater Management Permit Application for
Lots 17-23, Block 7A, Whalebone Beaches on October 19, 2005. Staff review of the plans and

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, 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.
Remove accumulated sediment from the pretreatment system and infiltration basin annually or when the 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 _1.65 feet in the pretreatment unit, the sediment shall be removed from both
the pretreatment unit and the infiltration basin.
S. 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.
