Dear Mr. Persiani:
The Wilmington Regional Office received a Stormwater Management Permit Application for Lot 201
Renovations-MCB on May 12, 1997. A preliminary review of that information has determined that the
application is not complete. The following information is needed to continue the stormwater review:
I. A revised permit application which reflects the numbers for built -upon area and project area
used in the calculations.
2. The need for a vegetated filter is not determined by whether or not the required surface area
is exceeded. By using the 90% TSS chart, you automatically bypass this requirement.
V 3. Extend the 6:1 vegetated shelf around the entire perimeter of the pond, not just in the
forebay, as currently depicted.
�j 4. Delineate all wetlands on site, or note on the plans that none exist.
J
5. Relocate the vegetated shelf so that it will be inundated periodically, ie., between 22 and 23.
6. Delete the O & M shown on the plans. A separate document has been submitted.

MCB-Lot 201 Renovations
Onslow County
Dear Mr. Persiani:
The Wilmington Regional Office received a Stormwater Management Permit Application for MCB-
Lot 201 Renovations on December 2, 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. Sealed calculations indicating the drainage area to the pond, the TSS removal chart used, the
required surface area at permanent pool based on the depth and percent impervious, the
required and provided volumes, and the orifice sized for a 2-5 day drawdown. If using 85 %
TSS, a vegetated filter is required at the outlet structure.
2. Signed Operation and Maintenance plan.
3. A 6:1 vegetated shelf around the pond's perimeter and a forebay are required. Please
add/revise details as needed. The forebay must be shallower than the pond (generally 3' deep
maximum), and must hold at least 20% of the total volume..
4. Delineate all wetlands on site, or note on the plans that none exist.
