C. Inspect the pond side slopes and grassed inlet swales; remove trash, and repair eroded
areas before the next rainfall event.
D. If the pond is operated with a vegetated filter, the .filter will be checked for sediment
accumulation, trash accumulation, erosion and proper operation of the flow spreader
mechanism. Repairs/cleaning will be done as necessary.

A. Inspect the collection system (ie. catch basins, piping, grassed swales) for proper
functioning. Accumulated trash will be cleared from basin grates, basin bottoms, and
piping will be checked for obstructions and cleared as required.
B. Pond inlet pipes will be checked for undercutting, riprap or other energy dissipation
structures will be replaced, and broken pipes will be repaired.
III. Semi-annually:
A. Accumulated sediment from the bottom of the outlet structure will be removed.
B. The pond depth will be checked at various points. If depth is reduced to 75 % of original
design depth or 3 feet whichever is greater, sediment will ,be removed to at least the
original design depth.
C. Grassed swales, including the vegetated filter if applicable, ill be reseeded twice a year

Dear Ms. Houston:
The Wilmington Regional Office received a Stormwater Management Permit Application for NHC
Community Health Center on May 7, 1996. A preliminary review of that information has determined that
the application is not complete. The following information is needed to continue the stormwater review:
1. Please note on the plans that all roof drains must be connected into the on -site stormwater
system and be directed into the pond.
2. Add the building dimensions.
3. Label the vegetated shelf width, the elevations to begin and end the shelf, and the forebay
depth on the forebay section detail.
4. The calculations,
plans, and
application form do not
