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. The chlorides test appears to have been taken at a point in Mill Creek that is upstream of the proposed discharge, and that is not outside a 1/2 mile arc. Please see the attached map. I have drawn in an arc in blue ink that has a radius of roughly 2,640', based on the scale provided. Since no bar scale was provided, I cannot verify whether or not the map scale has been reduced. I have marked an X in blue ink where the sample should be taken to provide an accurate determination of whether this site drains to SA waters or not. 2.

State of North Carolina .- Department of Environment I and Natural Resources Wilmington Regional OfficeEk ON Ain James B. Hunt, Jr., Governor Wayne McDevitt, Secretary NORTH CAROLINA DEPARTMENT OF Division of Water Quality ENVIRONMENT AND NATURAL RESOURCES December 14, 1998 Mr. Fred Cone, P.E. 1116 Greenway Road Jacksonville, NC 28546 Subject: ACKNOWLEDGEMENT OF RECEIPT AND REQUEST FOR ADDITIONAL INFORMATION Stormwater Project No. SW8 981020 CVS Pharmacy Stump Sound Onslow County Dear Mr. Cone: The Wilmington Regional Office received a Stormwater Management Permit Application for CVS Pharmacy Stump Sound on October 20, 1998. 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. Delineate all wetlands on site, or note on the plans that none exist. Please add the line symbol for wetlands to the legend. 2. Mill Creek is class SA waters. In order to allow a detention pond for stormwater treatment, please provide the results of a chlorides test taken at a point in the receiving stream that is at least 1/2 mile from the proposed discharge point, as the crow flies, and after 3 days without rain. If the chlorides are greater than 500 ppm, a pond cannot be used. Please include a quad sheet with the project site and sample site located. The remaining comments assume that a pond will be allowed. If not, please revise the submittal to an infiltration pond. 3. The supplement lists the storage elevation as 23.18, which is 4 feet BELOW the permanent pool. It appears this is a typo and should be 28.21, based on the pond detail. Please confirm. 4. The spaces for initials on the wet pond supplement form have been marked N/A. This is not acceptable. Each item must be intialled, as applicable to the project. For item f, a portable pump is an acceptable emergency drain; Item 1 is N/A, since you have used the 90% TSS table. 5. For purposes of determining percent impervious and required surface area, the drainage area to the pond is used. In this case, the DA is 75,090 sf. however, you then turn around and use 71,290 sf to determine the percent built-upon and required surface area. Please revise. 127 Cardinal Dr.Ext.;Wilmington,North Carolina 28405 Telephone 910-395-3900 FAX 910-350-2004 An Equal Opportunity Affirmative Action Employer 50% recycled/10°/ post-consumer paper Mr. Cone December 14, 1998 Stormwater Project No. SW8 981020 ---------------------------------------------- 6. The BMP document recommends a minimum 10' wide vegetated shelf. This project specifies a 2' wide shelf. Please revise. Aside from being extremely difficult to construct, the surface area is not affected by extending the shelf further under the permanent pool, and less excavation is needed. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to January 14, 1999, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. The Division is allowed 90 days from the receipt of a completed application to issue the permit. If you have any questions concerning this matter please feel free to call me at (910) 395-3900.
