In addition a resubmittal fee of $500.00 is enclosed. Below, is a summary of each revision in the order of your comments: I. The calculations have been signed and scaled by Thomas .I. Davis, P.E. and dated 10/ 10/2008. 2. The calculations for drawdown time for each pond's outlet orifice have been recalculated to reflect the fact that the head decreases as the drawdown occurs. 3. The drainage areas for Tarawa Terrace 5 South Pond and the Phase 6 pond have been revised to be consistent throughout the calculations, supplements and drainagc map. 4. The surface area for the Phase 6 temporary pool has been recalculated to the actual surface elevation of 16.14. 5. The drainage area now includes building 237 that was constructed during Phase 2 construction. Calculations for the Phase 5 South Pond now reflect the increase in drainage areas. 6. For Tarawa Terrace Phase 6, planshect C-5.05 has been revised to show the correct SHWT elevation and the increased change in size for the water quality orifice. For Phase 5, plansheet C-5.02 also has been revised to show the increased change in size for the water duality orifices for both the North and South Ponds. 7. A $500.00 check is enclosed made payable to the NCDENR. I believe that this revised submittal addresses all of your comments and concerns.

Sullins Director Division of Water Quality The Wilmington Regional Office received a State Stormwater Management Permit Application for Tarawa Terrace - Phases 1 - 6 on September 24, 2008. A preliminary review of that information has determined that the following information is needed to continue the stormwater review: 1. Provide calculations that have been sealed, signed and dated. The calculations provided with the application submittal were not signed or sealed. 2. The average head used to calculate the discharge rate and drawdown time from the pond should be calculated based on Section 3.5.2 of the 2007 BMP manual where the average head (H13) is used. With the current orifice sizes, it appears that the required storage volumes will drawdown in more than 5 days. Please resize the orifice so that the drawdown rate for the required minimum storage volume is between 2 and 5 days. 3. The drainage areas for the South pond in Phase 5 and the Phase 6 pond are inconsistent between the table provided in the application, the supplement, and the calculations. Also, the impervious areas presented in these documents for the Phase 6 pond are also inconsistent. Please verify the drainage areas and impervious areas are presented consistently and the ponds are sized appropriately. 4. The temporary pool surface area identified on the supplement for the Phase 6 pond appears to be the surface area at an elevation of 16 instead of 16.13, which is the temporary pool elevation identified on page 1 of the supplement. Please verify. 5. Provide an updated and accurate drainage area map. The one supplied with the submittal does not indicate that building 237 is included in the drainage area for the South pond in Phase 5. 6. The proposed pond profile and outlet structure detail for Phase 6 on plan sheet C-5.05 appears to have a few typos. Please verify the SHWT elevation and the temporary pool elevation. 7. Please submit a $500 fee for the additional review required for this application.

Date Received by LQS: February 21, 2007 Plan Type: NEW Dear Mr. Connor: Michael F. Easley, Governor William G. Ross Jr., Secretary This office has received a soil erosion and sediment control plan for the project listed above which was submitted as required by the North Carolina Sedimentation Pollution Control Act (G.S. 113A-57 (4)), The Act requires that all persons disturbing an area of one or more acres of land must obtain approval of a soil erosion control plan prior to the commencement of the land -disturbing activity (G.S. 113A-54(d) (4)). The Act further states that this plan must be filed a minimum of 30 days prior to the activity and the approving authority must approve or disapprove the submitted plan within 30 days of receipt. Failure of the approving authority to approve or disapprove the submitted plan within the 30-day period will be deemed approval of the plan. Commencement or continuation of a land -disturbing activity under the jurisdiction of this Act prior to the approval of an erosion and sediment control plan is a violation of the Act. We have performed a preliminary review of your submitted plan and have determined that additional information will be necessary before a final review can be completed. Enclosed is a checklist of items that must be submitted before we can complete the review process. Failure to provide the additional information may result in disapproval of your plan. The approval of an erosion and sediment control plan is conditioned on the applicant's compliance with Federal and State water quality laws, regulations and rules. If you have questions please do not hesitate to contact this office. Your cooperation in this matter is appreciated and we look forward to working with you on this project.

Copies can be requested from the central office in Raleigh at 919 733-4574 (Gray Hauser or Mell Nevils). Also, please read the pink sheet that commences with "Plan review can be more quickly expedited...". 2. While the telephone and fax numbers for Actus tend Lease are on the plans, please also provide this information on the Financial Responsibility Form in the blanks provided. 3. Plans should be submitted folded as close to 8'/2 x 11" as possible due to the way our files are set up. We need 3 copies of the erosion control plan sheet but only 1 copy of any incidental plan you feel supports the erosion control plans. 4. Silt fence should be used on small disturbed areas that are less than '/ acre per 100 feet of fence (per the North Carolina design manual). It appears that adequate sediment storage is not being provided. Also, no gaps should exist in coverage along the clearing limits or disturbed limits. 5. The proposed stormdrain system must be shown on the erosion control plan. A sediment trap or equal device must be located at the proposed outlets of the stormdrain system unless it dumps into the stormwater pond. Include phasing of construction on the construction sequence. 6. Existing topo elevations are on the erosion control plan, but are hard to read. Proposed grades are not shown on the plan but are required. 7. Please review the seeding specifications for the coastal plain area, well -drained sandy loams to dry sands from the design manual. Also note, mulch is required on all seeded areas — not just slopes. All slopes must be provided groundcover sufficient to restrain erosion within 21 days following any phase of grading. 8. Provide calculations for the proposed sediment basin along with the exterior dimensions. Also, denote where the basin will discharge. Please describe the phases of demolition and/or construction during which this proposed basin be constructed and utilized. Include on construction sequence. 9. Please discuss the stormdrain system, existing and proposed, in the project narrative and on the construction sequence. The current project narrative says that storm water runoff from the site drains into stormwater ponds. Is the Boy Scout Road pond existing? Please specify where the storm water is being discharged at the end of Tulagi Place. If this area is a wetland, it must be denoted as wetlands on the plans. 10. The construction sequence on the erosion control plan should contain the following note as number 1: Notify the Division of Land Resources prior to commencing work on this project, 910 796-7230. 11. Any proposed dewatering activities must be addressed on the erosion control plan. Wilmington Regional Office• 127 Cardinal Drive Extension, Wilmington, NC 28405 Phone: 910-395.3900 Fax: 910-350-2004
