Commons) Shallotte, Brunswick County. The following responses are to Linda Lewis' telephone request to me on 09/27/2006. L Two copies of revised calculation pages 4a and Sa covering forebay volumes and orfice size have been sealed and signed and are enclosed. 2. Two copies of the Storm Water Management Plan are submitted on "white print paper" rather than blue print copies originally . submitted. 3. The bottom elevation of the forebay has been revised to elevation 28.0 feet rather than decreasing the volume. 4. The project name was changed to "K.T. Commons" by the owner sometime in July or later? I did not learn of it until after the July submittals for this project. The project is the same with a new name. Please resume review of this project using the above requested information furnished. Sincerely, C5L i, fi* Eric J.

The additional information we requested was received on July 17, 2006. Our time frame for this permit is anytime prior to October 17, 2006, but we are running a little over 60 days at the moment, so I projected that it would be issued the last week of September. That was by no means a guarantee that the permit will be issued. The information submitted by the consultant still has to be reviewed for completeness and accuracy, and if ii is not, additional information will need to be requested again. Please be reminded that the 90 day time clock begins upon receipt of a complete application. I apologize for not being able to return your phone calls in a timely manner. I get upwards of 25 calls and over 5o emails daily, and it is simply impossible tc return them all and get my permit review work done. I make the choice to spend my time reviewing and issuing permits and put returning phone calls on the back burner because most of the calls I get are for permit status. The Shallotte Mini Mall is the next project for me to review and, if Mr. Matzke has adequately addressed each of the 18 deficiencies, you will have your permit by the,end of the week. However, it has been my experience that with so many deficiencies, other questions are bound to come up. Kamran Goudarzi is listed as the applicant, so you would not be able to pick up the permit- only Mr. Goudarzi can do that. We can certainly call you to let you know that the permit has been issued.

For your information our Project Engineer called your office several times last week, left messages, and his calls were never returned.

Ross Jr., secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.I-'. Director Division of Water Quality The Wilmington Regional Office received a Stormwater Management Permit Application for Commercial Mini Mall Shallotte on April 28, 2006. 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 provide the receiving stream name and classification in Section 111.6 of the application. Where does the road ditch end up? Please follow the drainage until it enters a named water body, and report that water body on the application. You can look up the water body and its classification on DWQ's home page at: http://h2o.enr.state.nc.us/bims/reports/reportsWB,html 2. Please complete Section VII, the agent authorization. This is the place to designate who will be providing the necessary information regarding the stormwater application, on your behalf. This is normally the design engineer. 3. Please hand initial the blanks on page 2 of the supplement form. 4. Please specify the type of vegetation to be planted on the side slopes of the pond and specify the type of wetland species to be planted on the 6:1 shelf. Please note that Weeping Love Grass is not recommended for use in North Carolina as either a temporary or permanent ground cover. 5. Please specify the width of the 6:1 shelf on the plan or section view of the pond. 6. The blanks on page 3 of the supplement above the pond section diagram are for the sediment removal depths, not elevations. Please report these numbers as depths. Additionally, the pond may never be less than 3' deep, so the sediment removal elevation would 28.5, which corresponds to a sediment removal depth of 3.0 feet. 7. Please print your name in the blank above your signature in Section VI11 of the application, to verify that it is your signature. 8. Please provide a phone number in Section 1.3 of the application, where you can be reached during normal business hours.

If the inclusion of the baffle has created the necessary 3:1 L:W ratio, please initial the appropriate blank on page 2 of the supplement. 10. Please delineate the 2.04 acre drainage area to this pond. The calculations indicate the possibility that the 2.04 acre DA contains some offsite drainage area. If so, please identify the offsite drainage area and it's acreage. Additionally, any offsite drainage that is not rerouted around the pond must be accounted for in the pond design at the full build -out potential. 11. Please use the minimum calculated 1" volume of 5,332 cubic feet to size the orifice. 12. Please report the forebay volume actually provided in the pond (3600 ftz?) on the supplement. The supplement appears to report only the minimum required forebay volume of 2,115 ft. The supplement should reflect all the provided elevations, areas and volumes for this pond, not the minimums. 13. Please provide the street address of the project in Section 1.5 of the application. 14. Please revise the top elevation of the baffle wall to at least the temporary pool elevation of 32.5, in order to act as a true means of providing a 3:1 L:W ratio in this pond. 15. Please provide dimensions for all of the proposed built -upon area including the building, parking lot and sidewalks. 16. There are no sidewalks noted on the plans, however, most commercial developments provide a sidewalk between the parking lot and the building in order for customers to access the building. Please locate, label and dimension the sidewalk. 17. The invert of the 4" PVC orifice pipe on the inside of the outlet structure should be set at the permanent pool elevation. The current configuration will cause the permanent pool to be somewhat higher than 31.5. 18. All slopes to be vegetated must be 3:1 or flatter. Unless the forebay slopes above the permanent pool are to be riprapped or stabilized by means other than vegetation, please grade them back to 3:1 or flatter. Please note that this request for additional information is in response to a preliminary review. The requested information should be received in this Office prior to August 10, 2006, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee.

Linear interpolation should be employed to determine the correct value for non- standard table.entrics. 2 In the 20 coastal counties, the requirement for a vegetative filter may be waived ifthe wet detention basin is designed to provide 90°iu TSS removal. The NCDENt2, BMP manual provides design tables for both 85% TSS removal and 90% TSS removal. III. 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 2FI .1008. Initial in the space provided to indicate the following design retluiretncnts 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. If a requirement has not been met, attach justification. Applicants Initials a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).' b. The forebay volume is approximately equal to 20% of the basin volume. r c. The temporary pool controls runoff from the design storm event. Y d. The temporary pool draws down in 2 to 5 days_ - M/A e. If required, a 30-foot vegetative filter is provided at the outlet (include non -erosive flow calculations) F. The basin length to width ratio is greater than 3:1. 115IN& BaFiFLEf> PA144 g. The basin side slopes above the permanent pool are no steeper than 3:1.— h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail). -~ i. Vegetative cover above the permanent pool elevation is specified.- j. A trash rack or similar device is provided for both the overflow and orifice.✓ k. A recorded drainage casement is provided for each basin including access to nearest right- of-way. 1. If the basic} is used for sediment and erosion control during construction, clean out of the basin is specified prior to use as a wet detention basin. r m. A mechanism is specified which will drain the basin for maintenance or an emergency. 1.11. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. "This systein (check one) -0 ddie f does not incorporate a vegetated tiller at the outlet. "This system (check one) -A-des $ does not incorporate pretreatment other than a forehay. Form SWU-102 Rev 3.99 Page 2 of 4 Maintenance activities shall be performed as follows: After every significant runoff producing rainfall event and at least monthly: a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation, vegetated cover, and general condition. b. Clieck and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within 2 to 5 days as designed. 2. Repair eroded areas immediately, rc-seed as necessary to maintain good vegetative cover, ITlow vegetative cover to maintain a maximum height of'six inches, and remove trash as needed. 1 Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain proper functioning. 4. Remove accumulated sediment from [tic wet detention basin system semi-annually or when depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of in an appropriate manner and shall be handled in a manner that will not adversely impact water duality (i.e. stockpiling near a wet detention basin or stream, etc.). ' The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads . �'—, feet in the main pond, the sediment shall be removed. When the permanent pool depth reads feet to the forebay, the sediment shall be. removed.
