Stormwater Permit No. SW8991140 Wilmington Bridge Maintenance Yard Division tll, East Side Brunswick County Dear Mr. Lee: Dee Freeman Secretary The Division of Water Quality issued a Coastal Stormwater Management Permit, Number SW8991140 to Wilmington Bridge Maintenance Yard Division III, East Side for a High Density Project on March B, 2000. This permit expires on March 8, 2010. Section .1003(h) of 15 A NCAC 2H .1000 (the stonnwater rules) requires that applications for permit renewals shall be submitted 180 days prior to the expiration of a permit and must be accompanied by a processing fee, which is currently set at $505.00. If this is still an active project please complete and submit the enclosed renewal application in a timely manner. If this project has not been constructed and a permit is no longer needed, please submit a request to have the permit rescinded. If you have sold the project, or are no longer the permittee, please provide the name, mailing address and phone number of the person or entity that is now responsible for this permit. Enclosed Is a form for change of ownership, which should be completed and submitted if the property has changed hands. Your permit requires that upon completion of construction and prior to operation of the permitted treatment units a certification of completion be submitted to the Division from an appropriate designer for the system installed. This is to certify that the permitted facility has been installed in accordance with the permit, the approved plans, specifications and supporting documentation. Please include a copy of the certification with your permit renewal request and processing fee. Enclosed is a copy of a sample certification. Also enclosed is a new Operation and Maintenance agreement that should be completed and submitted along with your renewal application. You should be aware that failure to provide the Designer's Certification and the operation of a stormwater treatment facility without a valid permit, are violations of NC General Statute 143-215.1 and may result in appropriate enforcement action including the assessment of civil penalties of up to $10,000 per day.

The permanent pond dimensions are shown on Sheet C-6. 2. The 30-foot vegetative filter has been relocated to an area farther from the wetlands and we now have the required length. 3. The amount of existing impervious area that presently flows untreated to the river is 1.1.3 acres (see Sheet C-1). The new project intercepts all but 0.15 acres of the existing impervious area and directs it to the pond for treatment (see Sheet C-4). We had to extend the collection system to the location shown. The grades do not allow us to put it farther down the ramp. 4. We have initialed Page 4. 5. We used the minimum 1" volume in the revised calculations. 6. The revised impervious percentage is based on the new impervious area and deletes the existing impervious areas. 7. The figures for impervious are now in square feet. 8.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: The grading shown for the vegetated filter suggests that it will be more of a swale rather than a flat grassed area. A swale is not acceptable for a vegetated filter. Please show the 7 contour straight across the filter, at right angles to the sides, not pointing upstream. The idea is to spread the flow out over the grass, not channelize it. 2. The total impervious area shown on the application appears to be a typo- 94,691, is reported, but if you add up the numbers shown in the breakdown area, they total 94,962 ftz. The total BUA reported in the lower section of the breakdown area is what gets carried to the upper section. If 94,691 is the total BUA that will drain to the pond, please revise the breakdown portion of the application to add up to 94,691. If 94,962 is the actual BUA to the pond, please correct the total on the application. Please note that the calculations use 94,961 ft2, so if you change the total to 94,691, you will also need to revise the calculations. The minimum required surface area is 5,123 ft2, but you now show on the supplement that only 5,103-ft2 is provided, rather than the 5,791 ft2 previously reported. Please provide additional surface area. Additionally, if you calculate the area as shown in the permanent pool dimension detail, it adds up to 5,362 ft', not 5,103. Please clarify, recalculate, and revise where needed. 127 Cardinal Dr. Ext., Wilmington, North Carolina 28405 Telephone 910-395-3900 FAX 910-350-2004 An Equal Opportunity Affirmative Action Employer 50% recycled110% post -consumer paper Mr. Lee February 11, 2000 Stormwater Project No. SW8 991140 Please note that this request for additional information is in response to a preliminary review.

Linear interpolation should be employed to determine the correct value for non- standard table entries. In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide 90% TSS removal. The NCDENR Bi1P manual provides design tables for both 85`!o TSS removal and 90% TSS removal. II. REQUIRED ITEMS CHECKLIST EAST SIDE — WET POND The following checklist outlines design requirements per the Stormwater Best Management Practices Manual (N.C.

The Elevation 7 contour has been drawn at the end of the vegetated filter. 2. I did transpose the numbers on the permit. The data in the calculations is correct. The total is 94,962 square feet. 3. In the last review letter, the impervious area was changed to account for the existing impervious area and the percent impervious was adjusted from 52.23% down to 50.7%. The surface area (5,791 sf) of the permanent pool was reduced accordingly after we re -drew the pond. When we use the acreage of 4.3 and interpolate for the 50.7% and recalculate the minimum surface area, we get 5,188 sf which is near your 5,123 sf. The dimensions on the detail sheet show 5,362 sf. When AutoCAD checks the areas with the radii at the ends of the contours, the surface area is slightly less but is more than 5,188. Please advise if you need more data.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Please provide the dimensions for each side of the figure created by the permanent pool contour. 2. The 30' of vegetated filter should be provided parallel with the flow. The detail provided 2 indicates only 20' of grass after the riprap, but a 30' width. The width is determined by.the flowrate, and is not automatically set at 30'. See the enclosed detail. 3. The area around the rear of the site at the boat ramps is allowed to sheet flow into the river without treatment. The rules require that all runoff from impervious areas be treated, however, 0j the site is being partially redeveloped. Please provide a calculation which demonstrates that the new runoff volume into the river is less than or equal to the existing amount of runoff into the river. Please delineate the before and after drainage areas for this calculation. If this requirement cannot be met, please provide additional stormwater control measures for the runoff. You may want to consider a sand filter, which is ideal for this type of application. Sand filters are small and do not need to meet the 2' separation from the water table because they have an impervious bottom. The BMP document distributed at the workshops outlines all the design requirments. ✓ 4. Please initial page 4 of 4 of the application. 5. As discussed at the workshops, please use the minimum 1" volume to size the orifice, not the volume actually provided. ,/ 6. Please recalculate the percent impervious and required volume. Based on 2.18 acres of impervious and a4.3 acre drainage area, the percent impervious is only 50.7%, not 52.23%. This will then reduce the required volume, and ultimately the orifice size needed. 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. Lee December 21, 1999 Stormwater Project No. SW8 991140 r/ 7 As discussed at the workshops, please report the impervious areas on the breakdown part of the application in square feet.
