Monthly, or after every runoff producing rainfall event, whichever comes first: A. Inspect the trash rack; remove accumulated debris, repair/replace if it is not functioning. B. Inspect and clear the orifice of any obstructions. If a pump is used as the drawdown mechanism, pump operation will be checked. A log of test runs of the pump will be kept on site and made available to DWQ personnel upon request. C. Inspect the pond side slopes and grassed inlet swales; remove trash, and repair eroded areas before the next rainfall event. D. If the pond is operated with a vegetated filter, the filter will be checked for sediment accumulation, trash accumulation, erosion and proper operation of the flow spreader mechanism. Repairs/cleaning will be done as necessary. II. Quarrtetly (Four times a year) : A. Inspect the collection system (ie. catch basins, piping, grassed swales) for proper functioning. Accumulated trash will be cleared from basin grates, basin bottoms, and piping will be checked for obstructions and cleaned as required. B. Pond inlet pipes will be checked for undercutting. Riprap or other enerQ structures will be replaced, and broken pipes will be by dissipation P repaired. I]iI. Semi-annually (twice a year): f:. A. Accumulated sediment from the bottom of the outlet structure will be removed. B. The forebay depth will be checked at various points. Sediment removal is required when the depth is reduced to 75 % of the original forebay design depth of * ( see }below) C.

Sediment removal is required when the depth is redyced to 75 % of the original design depth or T, whichever is greater. Design depth is *b418S)', measured vertically from the orifice down to the pond's bottom. �s Sediment must be removed to at least the original design depth. * Pond 31= Ft. 4 Ft. V. General: A. Mowing of the side slopes will be accomplished according to the season. Maximum grass height will be 6". B. Cattails are encouraged along the pond perimeter, however they will be removed when they cover more than 1/2 the surface area of the pond. The best time to cut them is at the end of the growing season, in November. Environmentally sensitive chemicals for use in killing cattails can also be used. Contact your nearest Agricultural Extension Agent. C. The orifice/pump is designed to draw down the pond iu 2-5 days. If drawdown is not accomplished in that time, the orifice will be replaced with a larger or smaller orifice. Slow dFawdown may be attributed to a clogged system. The source of the clogging will be found ' and eliminated. D. All components of the detention pond system will be kept in good woriana or replacement components will meet the original design a order. Repair b gn specifications as per the approved stormwater plan. If previously approved components are determined to be ineffective, the component must be redesigned and/or replaced.

Lowe's Home Center Morehead City, North Carolina July 2, 1998 STORMWATER TREATMENT USING WETLANDS Wetlands for use in stormwater treatment has been more recent than that for wastewater treatment. In that capacity, created wetlands have been shown to be most effective in controlling organic matter, suspended sediments, and nutrients (Mitsch and Gosselink 1993). When water flows to a wetland in an urban setting, it will include nutrients such as nitrogen and phosphorus, as well as sediments and other contaminants from auto residues, etc. Since nitrogen is often the most limiting nutrient in flooded soils, much attention has been given to the transformation of this particular nutrient. Wetlands often function well in nitrogen mineralization i.e. the transformation of organic nitrogen to forms which can be taken up by vegetation. This can be undertaken in processes such as ammonification. Suspended sediments are retained by the wetlands in wetting/drying cycles. Wetlands have been shown to be sinks for many of the materials that would be part of stormwater runoff that would result from a major shopping center. ti10pMWATER E C E I V E JUL 0 61998 D D E M PROJ # 'Taken from report dated 6125/98 provided by Land Management Group, Inc., Wilmington, NC.

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. In writing the permit, I could not determine where that portion of Outparcel #4, which is part of the drainage area for Pond #1, was included in the impervious area breakdown. The separate breakdown table provided does not include any "Other On -Site" impervious area in the column for Pond 1. In checking, it appears that the outparcel may have been left out of the design calculations. The BUA summary provided on the 11/30/98 drainage area delineation sheet indicates that the only outparcel accounted for in any pond design under this permit is #3. Has this now changed? Please clarify. Provide a revised tabular breakdown, and a .revised BUA summary, if required. 2. From the drainage area delineation plan, it appears that a little less than 1/2 of OP #4 will drain to Pond 1, and the rest will drain into Wetland #1. Has this portion of OP #4 been included in the 943,000 square feet of "Other On -Site" for Wetland #1? Is it your intention to. require that all the runoff from OP #4 be directed into Pond 1? If yes, then the drainage area delineation needs to show all of OP #4 within the drainage area of Pond 1. If OP #4 is not to be permitted at this time, please remove it from the drainage area of Pond 1. 3. What makes up the "Other On -Site" impervious area shown for Pond 3 and Wetland #44? The plans suggest that there isn't anything but buildings, asphalt (parkiAg and streets), or sidewalks comprising the built -upon area. If this is intended to be future area, please label it as future on the table, and show the location of the future area on the plans. 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. McCutcheon April 26, 1999 Stormwater Project No. SW8 980427 Please note that this request for additional information is in response to a preliminary review.

The revised pond calculations are now sealed by the Civil Engineer of Record. 2. A trash rack is not a prudent design measure for the overflow weir of the Pond 3 outlet structure. In our opinion, it is better for floating debris to be passed over this weir to allow unrestricted overflow of the pond during major storm events. For this reason, a trash rack has not been specified for this structure. 3. The areas to which you refer are drained onto the currently undeveloped area of Outparcels 2 and 3 and the designated future pond area. It is my opinion that this situation, given the relatively small proportion of impervious area, falls well within the intent of the stormwater treatment regulations. Stormwater from this area will flow to, and be effectively treated by, the established grass vegetation and soil infiltration before leaving the property. When these outparcels are developed, this impervious area would then be routed to appropriate BMP's for full build - out and permitted separately at that time. 4. A map is now submitted clearly identifying the outparcel and future development areas. It is true that no future development may occur within the wetland preservation areas; however, my client's arrangements do allow future paved vehicular circulation and parking areas within the ARCHITECTURE ENGINEERING PLANNING INTERIOR DESIGN no -build areas.

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 seal the revised pond design calculations. 2. The trash rack for the orifice outletting from Pond 3 has been provided, however, my last letter also requested that one be provided for the overflow weir. That is why I originally suggested vertical rebar along the top of the weir, spaced 3 -4 apart. Please revise. 3. The drainage area map provided indicates some new road areas that are not being collected and treated by either a pond or a wetland preservation area. All new impervious areas associated with this development must be directed into a treatment system. Please regrade these areas to flow into a proposed treatment system, and provide revised plans, supplement forms and calculations as needed 4. The plans do not clearly delineate the areas of future development. Is it correct to say that the future development areas are those areas that are not located within wetland preservation areas or no -build areas? Please label and provide boundaries for the future development and outparcel areas. 5. Wetland #1 is not listed on the application. This area appears to treat runoff from a portion of the new entrance road off of Highway 24. Please add to the application. Will this area treat any future impervious areas? Please establish a limit on the built -upon area to be treated in this wetland. 127 Cardinal Dr. Ert., 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. McCutcheon November 18, 1998 Stormwater Project No. SW8 980429 6.

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. There were no copies of a drainage area map included with the submittal. Please forward for review. 2. You're probably going to be better off letting Ponds 1 and 2 stand alone in terms of shortcircuiting. By relocating the single outlet structure, you now place Pond 2 in jeopardy of shortcircuiting, just as Pond 1 was when the outlet was located there. If each pond can function independently from a design standpoint, I would recommend deleting the equilibrium pipe and just provide outlets from both ponds. If the owners don't wish to do that, then the only recourse is to run ALL of the incoming runoff into ONE pond and let it function as the forebay, and then let it flow into the other pond via the equilibrium pipe and outlet from the other pond. 3. The outlet structure detail for Ponds 1 & 2 on sheet C10 still shows the overflow weir elevation (the design storage elevation) as 14, but your calculations indicate it as 13. Please clarify. 4. Please provide a trash rack for the outlet structure for Pond 3. The unorthodox design of the structure makes it a little more difficult to put in a trash rack, but I have seen similar outlets provide vertical rebar spaced about 3 "-4" apart as trash racks. The location of the orifice at the bottom is a potential clogging problem. Please provide some type of screening over it to keep it..clear, or negatively -slope. -the orifice pipe -so -that -the outlet -invert-is-at-12, and the inlet invert on the pond side is 6"42" below 12. An additional detail of the side view may be needed to illustrate the negative slope. r 9rdinsl r�-Carolinw-M -- �.ephsone�WO9-39"900-FAX-910-350-2004 �- _ An Equal Opportunity_Allirm-ativeAction Employee-:-- __-� 50%•recycled/10% post -consumer paper Mr. McCutcheon September 3, 1998 Stormwater Project No. SW8 980429 5. I am unable to locate the drawdown calculations for either pond. Please indicate where on the plans I can find these calculations which indicate that the specified orifice will drawdown the pond in 2-5 days. 6. The application still does not indicate the breakdown of impervious areas to be treated in each wetlands preservation area. The wetlands are part of the stormwater treatment for this project, and the design statistics must be included on the application just as the ponds are. The drainage area map must also show the drainage area for each wetland preserve area. 7. The design calculations presented on the plans are not matching up with the figures presented on the supplement sheets. I have summarized the differences below. Please make the necessary revisions. The supplement sheets will list the actual pond surface areas, volumes and orifice that will be provided, not the minimums required by the State.

Based on the volume provided for Pond 3, a 1" orifice, as specified on the outlet detail, is too small-drawdown occurs in 10 days. The 2.5" orifice specified on the supplement sheet is too large, and will draw down the pond in 1.6 days. The orifice size is based on the volume actually provided in the pond. Please resize this orifice and make the necessary revisions on the calculations, plans, details, and application supplement sheet. 9. The entire project is 39 acres, but only 11.6 acres have been accounted for in the drainage area of the ponds, and 6.22 acres is accounted for in the wetland recharge areas.

We are scheduled to meet with Tommy next week and we can put this one in front of him. I've attached a copy of a F&D I've worked up and I'd like for you to give it your review. I've tried to keep this one looking as much like previous cases as possible; I believe this is a knock off of one of the Ted Parker cases. In doing so, I've assumed some of the same procedures were followed as I saw in the earlier Ted Parker and Johnnie Mercer cases - that they first requested approval for an erosion control plan and we were notified by one of the land agencies of the potential activity. If that's so, can you tell me when we were notified and when we responded to say a stormwater permit would be required? If you have copies of any documentation that would be helpful for when we meet with Tommy. I cannot find any of this in Central Files. In Central Files, there was a file for another Lowe's development in Carteret County, perhaps at the same site. I think it was a 1995 file. Was this an earlier submittal for this site, submitted by another entity or was it something altogether different. I'm going to be out both tomorrow and Monday, so I'm not very available. If you can respond via e-mail, I can pick it up early Tuesdayand incorporate the information in the F&D or otherwise modify the document. Hope you have a Happy Thanksgiving.

The revised pond calculations are now sealed by the Civil Engineer of Record. 2. A trash rack is not a prudent design measure for the overflow weir of the Pond 3 outlet structure. In our opinion, it is better for floating debris to be passed over this weir to allow unrestricted overflow of the pond during major storm events. For this reason, a trash rack has not been specified for this structure. 3. The areas to which you refer are drained onto the currently undeveloped area of Outparcels 2 and 3 and the designated future pond area. It is my opinion that this situation, given the relatively small proportion of impervious area, falls well within the intent of the stormwa ter treatment regulations. Stormwater from this area wiii flow to, and be effectively treated by, the established grass vegetation and soil infiltration before leaving the property. When these outparcels are developed, this impervious area would then be routed to appropriate BMP's for full build - out and permitted separately at that time. 4. A map is now submitted clearly identifying the outparcel and future development areas. It is true that no future development may occur within the wetland preservation areas; however, my client's arrangements do allow future paved vehicular circulation and parking areas within the ARCHITECTURE • ENGINEERING • PLANNING • INTERIOR DESIGN no -build areas. -The term "no -build" refers specifically to buildings in this case. 5. Wetland Preservation Area No. 1 is now included on the application. 6. The supplement form, calculations and breakdown for Pond No. 2 are now clarified within the application package to be 85%.

SUBJECT: Evaluation and test results of the Hestron-TRIBEK tract as to NCDEH&NR-DWQ water quality standards for detention or infiltration stormwater usage. Tract located between U.S. Hwy 70 and NC Hwy 24, Morehead City west area, Carteret County, North Carolina. TO: TRIBEK & Mr. Perry McCutcheon Isom Associates, PA 1311 Collegiate Drive Wilkesboro, NC 28697 (336) 838-4007 NCDEH&NR "Stormwater Runoff Disposal' rules and regulations (NCAC 15-2H-.1000) were used as guidelines in making this evaluation. The proposed project site is greater than 1 acre in size and has >25% impervious surfaces which requires stormwater treatment of all run-off waters from impervious surfaces. If the proposed site drains to Class S.A. Waters infiltration basins must be utilized versus detention ponds. Class S.A. Waters are determined for stonrA ater purposes as waters that exceed 500 mg/I chloride content, after +3 days of insignificant rainfall, and during a median tide time period. The sampling point for water classification is 0.5 mile from the project site down -gradient along the primary drainageway. The enclosed map shows the project site (see map), and the water sampling point which is -0.50 miles from the from the project site along a drainage tributary towards the Newport River. Two separate water samples were taken on 06/17/98 at -11:50 a.m. for chloride content. The last significant rainfall was on 06/13/98 and high tide was at -1:30 p.m. on 06/17/98. The samples were taken to Environmental Chemists Inc (NCDEHNR-DWQ #94; DLS #37729) for chloride analysis. These samples show a chloride content of -53 mg/I which is well below the standard of 500 mgll for S.A. Water classification (see lab test results). Based upon these samples and standards the drainageway waters -0.5 miles down -gradient from the project site are not S.A. Waters. Thus the Hestron-TRIBEK project should be allowed to utilize detention ponds for stormwater treatment purposes. ;��- � l*,�I/c S1UHMVVAfER <LaF. aCPSS/SC NCLSS #1040; ARCPACS #2183 D E C E I V E JUL 0 61998 D D E M PROJ # I�IJK� I AINL �.�rLVL G 1 11.E o u rX v u 1 5653 IV SE (NEWPOR T) 335 2 - 1152 �' ; • 'i� •/r • 1153 IN jls17 '� f•'l • rl 11 1 l% N St ka s !I I ' • C•haaf11 pow 2 �Traile: IIII Park xote / a / f /III r/ ■ loseall ' I ■ II N 1 • • • �• • `N lob I I _ ■ ■ • . 11 ■ • , • � Ili ■ _ ■ • It. • > bey-beaca.n a QaYbeacon &Light vir hem Environmental Chemists, Inc. ® MAILING ADDRESS: TELEPHONE: SHIPPING ADDRESS: 41400wP.O.

I also want to formalize the changes that you requested for the application. Concerning the on -site mitigation effort, Hestron Corp. agreed that a planting plan would be provided. Juncus effusus, Typha lafifolia, and Sarurus cenurus will be planted throughout the creation, restoration and enhancement areas with Nyssa sylvatica and Acer rubrum planted at approximately 8' intervals along the wetland edges. Species planted are flexible and subject to your approval. As mentioned in my letter to Mickey Sugg (dated April 8, 1997), a monitoring well and vegetation sample plot will be located in the restoration area and creation area of the Hestron Tract, as well as in the enhancement area of the Bob -a -Lou tract. All areas will be monitored for five years. The off -site mitigation changes you proposed will also be implemented. All ditches will be filled with suitable fill material (rather than plugged). A monitoring well will be established in the preservation area for use as a reference site. Hydrological success criteria will be the maintenance of wetland hydrology for 12.5% of the growing season during normal precipitation conditions or the maintenance of a hydroperiod as long as that of the reference site. A final stormwater plan will be submitted with stormwater ponds moved to utilize the wetlands as post rather than pre-treatment areas. A final site plan will be sent to your office within a week. This site plan will not significantly change the amount of wetland area impacted but will be redrawn to better satisfy the client's needs and to allow for a more efficient stormwater plan. On behalf of Land Management Group and Hestron Corp., 1 would like to thank you and Linda for meeting with us and providing your inputs. We would appreciate your sending us 401 water quality certification approval as soon as possible. If you have questions in the meantime, please contact Lary Baldwin or myself.

This shall include all labor, materials and equipment necessary to meet the requirements of this section. GENERAL It is the intent of this specification that the Project and the Contractor comply with all applicable state and local erosion and sedimentation control laws and ordinances. The Contractor is responsible for maintaining all sediment and erosion control measures on the project site during construction. The Contractor is responsible for any damage caused due to failure to implement these requirements. PLANS A Soil Erosion and Sedimentation Control Plan is included in the Contract Documents and is to be implemented as a part of the procedures necessary to implement requirements as set forth by state and local ordinances. REV: 06-19-97 DIVISION 2 REV: 01-03-95 PAGE 7 OF 32 "This sheet is subject to those terms and conditions set forth on the cover page forwarded herewith." Implementation of the requirements of the Plan is based on the following principles: ' The disturbed area and the duration of exposure to erosion elements should be minimized. 2. Stabilize disturbed areas immediately. Retain or accumulate runoff. 4. Retain sediment. 5. Do not encroach upon watercourses. The Soil Erosion and Sedimentation Control Plan contains standard symbols for the different types of measures. These symbols are defined for conditions, design criteria and construction specifications and are detailed on the Drawings. 1. All disturbed areas shall be grassed by sodding or seeding, fertilizing, mulching and watering to obtain a ground cover which prevents soil erosion. As outlined under Section 02930 - Lawns and Grasses. 2. A temporary construction egress pad shall be installed and maintained at any point where construction vehicles enter a public right-of-way, street or parking area. The pad shall be used to eliminate mud from the construction area onto public rights -of -way. The pad shall be constructed as shown on the Drawings. Any mud or debris tracked on streets shall be cleaned up immediately. 3. All measures installed for sediment control shall be checked at the beginning and end of each day when construction is occurring to ascertain that the measures are in place and functioning properly. Any damage observed will be repaired by the end of that working day. Measures shall be maintained until they are called to be removed on the Plans. UiLLI�� I Y: Yu I ►Y The soils under the main building pad shall be treated for termite protection using the following concentration of soil treatment chemicals: Dursban TC 1.0% Applied In Water Emulsion After the installation of gravel fill, prior to slab placement, apply 1.5 gallons of diluted chemical per 10 square feet of area.

Trenches shall not be excavated wider than one (F) foot, six (6") inches, plus the nominal diameter of the pipe at the point twelve (12") inches above the level of the crown on the pipe. Depth of excavation shall be such that a minimum of 42" compacted fill is provided over top of pipe. The Contractor shall provide adequate facilities for promptly removing water from all excavation. The trench shall be excavated to the required depth and width and bell holes dug in the bedding in advance of pipe laying. The laying of gravity sewer pipes in finished trenches shall be commenced at the lowest point so that the spigot ends point in the direction of the flow. All pipes shall be laid with ends abutting and true to the line and grade indicated on the Drawings or as directed by the Owner. They shall be fitted and matched so that when laid in the work they will form a sewer with a smooth and uniform invert. All gravity sewer shall be bedded in accordance with manufacturer's recommendation for the proposed depth of sewer, and as may be detailed in the contract drawings. In no case will the supporting of pipes on blocks or earth mounds be permitted. REV: 11-25-96 DIVISION 2 REV: 08-06-97 PAGE 22 OF 32 All open ends of the pipe and of branches shall be sealed with stoppers or bulkheads firmly held in place in a manner acceptable to the Owner. Open ends of unfinished pipe lines shall be securely plugged or closed at the end of each day's work or when the line is left temporarily at any other time. The Contractor shall notify the Owner and local authorities when the pipe will be received on the job so that arrangements may be made for inspecting the pipe. Before the Contractor backfills any of the lines_ they shall first notify the Owner and Local Authorities. The Local Authorities shall ,give the Contractor permission to proceed with the ¢filling. The Contractor shall provide 48 hours notice prior to inspection. If any joints, pipes, or other workmanship or materials are found to be defective, they shall be removed and replaced. FINAL INSPECTION OF GRAVTTY SEWER LINES Prior to final acceptance of completed sewer lines, the lines shall be inspected and/or tested to ensure compliance with the following provisions: A. After the sewer lines have been brought to completion and prior to final inspection, the Contractor shall clean out the entire system by pushing through each individual line in the system from manhole to manhole appropriate tools for the removal from the lines of any and all debris and obstructions or may, if possible, flush clean with water or remove by hand. B. All lines or'sections of lines that are found to be laid improperly with respect to line and grade, that are found to contain broken sections of pipe, or are obstructed in such a manner that they cannot be satisfactorily corrected otherwise, shall be removed and replaced. C. The Contractor will be required to lay sewer lines so that the ground water infiltration shall not average more than twenty-five (25) gallons per twenty-four (24) hours per inch of nominal diameter per mile of sewer. These requirements may be applied to any single section of line. In order to test such infiltration, the Owner may require that the Contractor plug the open ends of all lines so that measurements may be made at each section of the sewer line. . D. The Contractor will be required to perform a low pressure air test on twelve (12") inches and smaller sewer lines as a condition to final acceptance. The lines will be tested end to end. Basically, the test will consist of installing a special pneumatic plug in the line and pressurizing the line to about 4 psi. After a two (2) minute temperature stabilization period, the line pressure is brought to 3.5 psi and timing is begun with a stop watch. The time required for a drop in pressure of one (1) psi will be recorded. The minimum time in minutes for this pressure drop of one (1) psi will be recorded. The minimum allowable time in minutes for this pressure drop to occur shall not exceed 0.472 times the inside pipe diameter. For example, on a twelve (I2") inch pipe this would be 0.472 x 12 = 5.664 minutes, or five (5) minutes, forty (40) seconds. If the time for the one (1) psi pressure drop is less than the calculated value, the line shall be repaired and re -tested until it passes the test. The test will be conducted in the presence of the Owner and a complete tabulated report of the tests for each section of the sewer will be prepared and submitted to the Owner. E. Sewer lines that do not meet the air testing requirements will not be accepted. The Contractor shall be responsible for all costs associated with corrective measures required for the sewer lines to pass this test. r1EV: 1"1-96 DIF;'ISION 2 REV: 11-25-96 PAGE 23 OF 32 "This sheet is subject to those terms and conditions set forth on the cover page forwarded herewith."

The site is entirely undevelopec property. Stormwater leaves the site to the north via sheet and ditchline flow into fhe US70 ditch and culvert system. There is a single drainage ditch crossing the property that is a part of the Cypress Bay Shopping Center stormwater management outfall. Proposed Conditions... A large portion of rainfall falling c)n the site will be dispersed by a system of drainage structures, RC pipes, curb flumes and grassed swales to two separate coastal forebay/pond systems with appropriate temporary pool draw -down times. The remaining smaller portion cf rainfall will be discharged directly into wetland enhancement areas for wetland recharge as required by the Corps of Engineers. Pond numbers 1 and 2 are designed with a system of weirs to backflow into a wetland enhancement area for ietland recharge. Pond number 2 forebay is provided for future outparcel development. Pond number 3 is designed to outfall to yet another wetland enhancer. ent area as required by the Corps. Eventually, stormwater from the site entersthe US70 drainage system as under current conditions. Stormwater Treatment... The forebays and ponds are sized per the 90% TSS removal chart. Stormwater discharged from the ponds will be properly treated. Stormwater that is discharged directly into wetland enhancement areas is thought to be properly treated in the wetlands.
