This permit shall be effective from the date of issuance until December 4, 2012, and shall be subject to the following specified conditions and limitations: I. DESIGN STANDARDS 1. This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data. 2. This stormwater system has been approved for the management of stormwater runoff as described on pages 4 and 5 of this permit, the Project Data Sheets. The wet ponds must provide storage for the runoff from a 1.5" storm event over each individual drainage area. 3. The flow from the orifice of the wet pond must discharge into a spreader swale designed to force a sheet flow runoff condition into the bermed infiltration area. 4. The orifice size has been designed to allow the wet ponds to draw down in 4 days, therefore the infiltration basin has been designed to store and infiltrate a maximum volume per day equivalent to the total volume pumped to the basin from each pond within the first 24 hours of a 1.5" rain event. 5. The tract will be limited to the amount of built-upon area indicated on pages 4 and 5 of this permit, and per the approved plans. The maximum total built-upon area allowed on the site is 605,360 square feet. 6. All overflows in excess of the 1.5" design storm from the wet ponds must pass through a 2 State Stormwater Management Systems Permit No. SW8 011119Mod 50' vegetated filter. 7. The runoff from all built-upon area within the permitted drainage area of this project must be directed into the permitted stormwater control system, as shown on the approved drainage area plan. 8. Within the 575'AEC, the percent impervious must be maintained at 25% or less. For the entire Mayfaire development, the area of the AEC is 59.28 acres, and the proposed built- upon area within the 575'AEC is 14.5 acres. 3 State Stormwater Management Systems Permit No. SW8 011119Mod DIVISION OF WATER QUALITY PROJECT DESIGN DATA SHEET Project Name: The Village at Mayfaire (Infiltration Basin) Permit Number: SW8 011119 Location: New Hanover County Applicant: Ms. Jessica L.

Instream analytical monitoring shall be conducted quarterly, concurrent with documentation of a system inspection. In addition, instream monitoring shall be required during four representative storm events in each year of the permit. Monitoring sites shall be selected both upstream and downstream of the project site on Howe Creek. Monitoring sites shall be selected by agreement between the permittee and the Division. 5. Each BMP shall be monitored. Grab samples shall be obtained at specified locations in the BMP to demonstrate the efficiency of the practices (inflow/outflow). The sample locations will be determined by agreement of the permittee and the Division. Monitoring of the BMP's shall be concurrent with the instream storm event monitoring. 3 BMP samples shall consist of a grab sample of the first flush inflow and the discharge outflow. The first flush inflow sample window is within the first 30 minutes of a discernable inflow from a representative storm event. The discharge outflow sample window is within the first 30 minutes of discharge from a representative storm event. Samples must be collected in each quarter of each year of the permit. 4. Monitoring parameters shall include, at a minimum, the below-listed items, a. -h. Additional monitoring parameters may be required later to address water quality issues in the affected area. a. Total Suspended Solids C. Temperature b. Turbidity f. Conductivity C. Fecal Coliform g. Flow d. Dissolved Oxygen h. pH 5. All samples shall be collected from a represcntative storm event. A representative storm event is an event that measures greater than 0.1 inches of rainfall and that is breceded by at least 72 hours during which no storm event measuring greater than 0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no 7 State Stormwater Management Systems Permit No. SW8 011119Mod precipitation. For example, if it rains for 2 hours without producing any collectible discharge, and then stops, a sample may be collected if a rain producing discharge begins again within the next 10 hours. The storm event date, total rainfall and duration must be recorded for both the storm event prior to the sampled event and the sampled event. 6. The permittee shall split samples with the DWQ for at least one sample event per year. The permittee shall make arrangements with Regional Office staff to deliver the samples to a State-certified lab, certified for the necessary parameters. Since Flow and Temperature samples cannot be split, they are excluded from the split sample requirement. 7. The use of portable meters for measuring Temperature, Turbidity,Flow,pH,Dissolved Oxygen and Conductivity is approved, as long as "Standard Methods" are followed. 8. All sample results shall be submitted to NCDENR within 30 days of receiving the laboratory results. All submitted data shall reference the project name, location, and permit number. Results must be submitted to: NCDENR-DWQ Stormwater and General Permits Unit 1617 Mail Service Center Raleigh,NC 27699-1617 A copy of the lab sampling results shall also be submitted to: NCDENR-DWQ Wilmington Regional Office 127 Cardinal Drive Extension Wilmington,NC 28405. 9. The permittee may petition DWQ to have monitoring requirements modified, reduced, or eliminated after 10 valid data points have been submitted for each BMP. The permittee may opt to monitor more frequently than quarterly to generate the 10 required data points from 10 different storms, as long as the data is collected over the course of at least one full year with samples collected in each season. Modification shall be determined on a case-by-case basis. 10. The permittee shall submit a map designating all sampling point locations, as agreed to between the permittee and the Division. III. GENERAL CONDITIONS 1. This permit is not transferable. In the event there is a desire for the facilities to change ownership, or there is a name change of the Permittee, a formal permit request must be submitted to the Division of Water Quality accompanied by an application fee, documentation from the parties involved, and other supporting materials as may be appropriate.

The collected samples are to be analyzed for total suspended solids, turbidity and fecal coliform by a certified analytical lab; the samples are to be field analyzed by MACTEC for dissolved oxygen, temperature, l conductivity, flow and pH. ➢ lnstream monitoring is required during four representative storm events in i each year of the permit. Each BMP at the Village at Mayfaire site; three wet detention storage ponds, shall be monitored concurrently with the instream storm event monitoring(4 events per year). Grab samples shall be obtained at specified locations in the BMP to demonstrate the efficiency of the practices L (inflow/outflow). The collected samples are to be analyzed for total suspended solids, turbidity and fecal coliform by a certified analytical lab; the samples are to be field analyzed by MACTEC for dissolved oxygen, temperature, conductivity, flow and pH. ➢ One sample event per year will be "split" with the DWQ. The samples will be delivered to a State-certified lab; since flow and temperature samples 1 I The Village at Mayfaire—Monitoring Services for Permit Compliance November 28,2007 MACTEC Project No.6550-03-0070 cannot be split,they will be excluded from the split sample requirement. The split sample event is scheduled to occur during the March sampling event. I 2.0 THE VILLAGE AT MAYFAIRE This section presents the results from field activities and laboratory analysis for the t f Village at Mayfaire site. l t 2.1 Semiannual Inspection by a P.E. Semiannual scheduled inspections are required to be performed by a Professional Engineer (P.E.) every six months to assure that the permitted stormwater system at the Mayfaire Town Center site functions at optimum efficiency. These inspections are scheduled to occur during the June and December (second and fourth calendar quarters) sampling events. No inspection was performed by a P.E. during the third quarter of 2007. 2.2 Instream Analytical Monitoring Instream analytical monitoring is required to be conducted quarterly, concurrent with documentation of a system inspection. Two surface water monitoring sites have been selected after negotiation with the DWQ. On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate surface water monitoring locations. Two surface water monitoring sites have been selected on the unnamed tributary of Howe Creek that runs through the site; one upstream and one downstream of the Village at Mayfaire site. The surface water monitoring locations are I ` illustrated on the attached Figures 1 and 2. Latitude and longitude coordinates were obtained in the field by MACTEC on December 8, 2004; these coordinates are included on Figures 1 and 2. On August 6, 2007, MACTEC attempted to conduct the instream analytical monitoring Levent for the third quarter of 2007 at the Village at Mayfaire site. MACTEC could not collect the required samples due to very dry conditions of the summer months. As a 2 L i The Village at Mayfaire—Monitoring Services for Permit Compliance November 28,2007 MACTEC Project No. 6550-03-0070 result, the field sampling worksheet and the laboratory analytical cal data for the instream analytical monitoring event (normally included in Appendix A as well as the results of the sampling event usually listed in Table 1 were P 8 y ) e left blank at this time. The classifications assigned to the waters of the State of North Carolina are based upon existing or contemplated best usage of the various streams and segments of streams in the basin determined through studies and evalVations'and the holding of public hearing for consideration of the classifications. According to 15A NC-AC 02B .0311, Howe Creek is considered a class SA Outstanding Resource Water (SA ORW) from its source to the Intracoastal Waterway. In Howe Creek, the fecal coliform standard is based on the median value of five readings in a 30-day period; the median value is not to exceed 14 colonies per 100 mL of water. The table showing all results of all fecal coliform sampling for August 2007 is normally attached as Table 2; the laboratory analytical results for the additional fecal coliform sampling events are usually included in Appendix r B. According to 15A NCAC 02B .0220 "violations of the fecal coliform standard are expected during rainfall events and, in some cases, this violation is expected to be caused by uncontrollable nonpoint source pollution" As previously mentioned, the results of the surface water sampling event for this quarter { could not be determined because samples could not be collected due to very dry conditions, therefore correlating tables are blank at this time. t 2.3 Storm Event Monitoring I A representative storm event is defined as an event that measures greater than 0.1 inches of rainfall that is preceded by at least 72 hours during which no storm event measuring greater than 0.1 inches has occurred. Accordingthe State to e Stormwater Management permit, each BMP must be monitored during a representative storm event to demonstrate the efficiency of the practices (inflow/outflow). BMP samples must consist of a grab sample of the first flush inflow and the discharge outflow. The first flush inflow sample window is within the first 30 minutes of a discernable inflow from a representative storm L 3 M The Village at Mayfaire—Monitoring Services for Permit Compliance November 28,2007 MACTEC Project No.6550-03-0070 event; the discharge outflow sample window is within the first 30 minutes of discharge from a representative storm event. The permit requires that this storm event monitoring be conducted quarterly (March, June, September, and December), and instream samples (- must also be collected during this event. On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate BMP sampling locations. Although four BMP structures exist at the Village at Mayfaire site, Wet Detention Pond 1, Wet Detention Pond 2, Wet Detention Pond 3, and Holding Pond 4, it will only be necessary to monitor the "outflow" structure for three of these areas. Holding Pond 4 does not have a typical "outflow" structure; the water in this pond is pumped to the other BMPs when the level is high using a transfer pump. It will not be necessary to collect "outflow" samples from this location. Detention Pond 3 is comprised of 2 separate cells; the "inflow" sampling location has been designated as the structure where the west cell flows f into the east (final) cell. MAC T EC will collect the "outflow" samples from the outflow structure on each of the ponds by dipping a sample probe through the grate on the top of the outflow box at each of the ponds. The BMP monitoring locations are illustrated on the attached Figure 2. A rain gauge is located on the Village at Mayfaire site; this gauge is monitored after storm events by MACTEC. On September 20, 2007, it began to rain over 0.1 inches (a total of 0.7 inches) at the Mayfaire site; prior to this event, a measurable amount of rainfall (equal to or greater than 0.1 inches) had not been recorded since September 17, 2007 (0.7 inches). Samples were collected from the outflow structures at each of the four { BMPs. Samples were collected from the inflow structures at all four of the BMPs. L MACTEC did not go to each of the surface water sample locations, which includes Howe Creek Upstream and Downstream because both sampling points were dry. The collected samples were analyzed for dissolved oxygen, temperature, conductivity, flow, and pH. d Samples for total suspended solids, turbidity, and fecal coliform were collected in 4 The Village at Mayfaire—Monitoring Services for Permit Compliance November 28,2007 MACTEC Project No.6550-03-0070 Ilaboratory prepared bottles, placed in an ice-filled cooler, and hand-delivered to F Environmental Chemists,Inc., in Wilmington,North Carolina for analysis. F The field sampling worksheet and the laboratory analytical data for the storm monitoring event are included in Appendix C. The results of the sampling event are also listed in Table 3. IWater quality standards exist for the surface water samples collected from Howe Creek; however, no formal standards are established for the pond discharges. It should be noted that these ponds are used as a habitat by Canadian Geese and other waterfowl native to the site area; it is expected that fecal coliform readings will be significantly elevated in the ponds. f As illustrated on the tables,the results of the storm sampling event for September 20, 2007 show fecal coliform levels for ull locations sampled to be out of compliance with i the 15A NCAC 2B standards. It should also be noted that levels were high for all Pond Inflow locations with readings of>60,000 colonies/100 ml water. The results exceed the 15ANCAC 2B standard of 14 colonies/100 mL water. (Please note the standard is based on 5 readings during a month.) Dissolved Oxygen for all locations sampled were also out of compliance except for Pond 1 Inflow and Pond 2 Inflow. It is assumed that dissolved oxygen levels were low due to increased water temperatures as a result of the hot dry weather and low rainfall commonly experienced this time of year.

Last Tuesday, November 13, 2007, 1 hand delivered a stormwater permit transfer resubmittal package (white binder)to your attention at DENR's office in Wilmington, NC requesting transfer of the stormwater permit from The Village at Mayfaire, LLC (the developer)to The Village at Mayfaire Condominium Owners Association. The initial request for transfer was returned to me with correspondence from you stating four criteria were required to be addressed before the permit would be transferred. Your comments have since been addressed and supporting documentation, along with a copy of your letter, are included and individually tabbed in the binder delivered to you. It is my understanding that you are scheduled to be out of the office beginning in early December. I have communicated to the Association, which recently elected a new Board of Directors comprised of unit owners, that the resubmittal has been delivered to DENR. Since our request for transfer is a resubmittal (vs. a new submittal), would you or a member of your staff review and process the resubmittal prior to your departure. The Association and the developer would appreciate compieting the transfer in 2007. Thank you.

The permit for the Village at Mayfaire was issued December 4, 2002, permit number SW8 011119; this permit is set to expire December 4, 2012. Monitoring requirements are outlined in Section III of the permit, and include the following elements: ➢ Semiannual scheduled inspections (every 6 months) by a Professional Engineer (P.E.) to assure that the permitted stormwater system functions at optimum efficiency. These records must indicate the date, activity, name of person performing the work and what actions were taken. These inspections are scheduled to occur during the second and fourth quarter sampling events. ➢ Instream analytical monitoring shall be conducted quarterly.(March, June, September, and December), concurrent with documentation of a system inspection. The collected samples are to be analyzed for total suspended solids, turbidity and fecal coliform by a certified analytical lab; the samples are to be field analyzed by MACTEC for dissolved oxygen, temperature, conductivity,flow and pH. ➢ Instream monitoring is required during four representative storm events in each year of the permit. Each BMP at the Village at Mayfaire site; three wet detention storage ponds, shall be monitored concurrently with the instream storm event monitoring(4 events per year). Grab samples shall be obtained at specified locations in the BMP to demonstrate the efficiency of the practices (inflow/outflow). The collected samples are to be analyzed for total suspended solids,turbidity and fecal coliform by a certified analytical lab; the samples are to be field analyzed by MACTEC for dissolved oxygen, temperature, conductivity, flow and pH. ➢ One sample event per year will be "split" with the DWQ. The samples will be delivered to a State-certified lab;' since flow and temperature samples P:IProjectslCL1ENTYState Street(Village at Mayfaire)10wrterly Reports1200712nd Quater 2007L?nd gtr 2007 report.doc 1 i The Village at Mayfaire—Monitoring Services for Permit Compliance August 14,2007 MACTEC Project No.6550-03-0070 cannot be split, they will be excluded from the split sample requirement. The r split sample event is scheduled to occur during the March sampling event. 2.0 THE VILLAGE AT MAYFAIRE This section presents the results from field activities and laboratory analysis for the Village at Mayfaire site. 2.1 Semiannual Inspection by a P.E. On July 2, 2007, Daniel C. Shields (licensed Professional Engineer in the state of North Carolina) conducted an inspection of the stormwater system in operation at the Village at Mayfaire site. During the inspection, the system was observed to be operating as intended and no maintenance or corrections were necessary at this time, other than items t included on the weekly reports. l - - �' 2.2 Instream Analytical Monitoring Instream analytical monitoring is required to be conducted quarterly, concurrent with documentation of a system inspection. Two surface water monitoring sites have been selected after negotiation with the DWQ. On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate surface water monitoring locations. Two surface water monitoring sites have been selected on the unnamed tributary of Howe Creek that runs through the site; one upstream and one downstream of the Village at Mayfaire site. The surface water monitoring locations are illustrated on the attached Figures 1 and 2. Latitude and longitude coordinates were obtained in the field by MACTEC on December 8, 2004; these coordinates are included on Figures 1 and 2. L On April 30, 2007, MACTEC went to the Village at Mayfaire site to conduct the instream analytical monitoring event for the second quarter of 2007. MACTEC went to each of the two pre-determined surface water sample locations, and collected samples to be field L P.IProjectsICUENMtate Street(Village at Mayfaire)lQuarterly Reports1200712nd Quater 200712nd qtr 2007 report.doc 2 i The Village at Mayfaire—Monitoring Servicesfor Permit Compliance August 14,2007 MACTEC Project No.6550-03-0070 Ianalyzed for dissolved oxygen, temperature, conductivity, flow, and H. Unfortunately Y (` samples for the Howe Creek Upstream location could not be acquired due to very dry weather conditions. Howe Creek Downstream was the only location sampled at this time. Samples for total suspended solids, turbidity, and fecal coliform were collected in laboratory prepared bottles, placed in an ice-filled cooler, and hand-delivered to Environmental Chemists, Inc., in Wilmington,North Carolina for analysis. The field sampling worksheet and the laboratory analytical data for the instream analytical monitoring event are included in Appendix A. The results of the sampling fevent are also listed in Table 1. The classifications assigned to the waters of the State of North Carolina are based upon existing or contemplated best usage of the various streams and segments of streams in the basin determined through studies and evaluations and the holding of public hearing for consideration of the classffiications. According to 15A NCAC "v2B .0311, Howe Creek is considered a class SA Outstanding Resource Water (SA ORW) from its source to the Intracoastal Waterway. In Howe Creek, the fecal coliform standard is based on the median value of five readings in a-30-day period; the median value is not to exceed 14 colonies per 100 mL of water. The table showing all results of all fecal coliform sampling for February 2007 is attached as Table 2; the laboratory analytical results for the additional fecal coliform sampling events are included in Appendix B. According to 15A NCAC 02B .0220 "violations of the fecal coliform standard are expected during rainfall events and, in some cases, this violation is expected to be caused by uncontrollable nonpoint source pollution" As illustrated on the tables, the results of the surface water sampling event for April 30, 2007 show the unnamed tributary of Howe Creek Downstream that runs through the Mayfaire site to be out of compliance with the 15A NCAC 2B standards, except for pH. Howe Creek Upstream was dry and therefore not sampled as previously mentioned. The water level at this sampling point was very low and appeared to be very stagnant on the P:IProjectsICL1ENTSIState Street(Village at Mayfaire)IQuarterly Reports1200712nd Quater 2007Und gtr 2007 report.doc 3 1 The Village at Mayfaire—Monitoring Services for Permit Compliance August 14,2007 rMACTEC Project No.6550-03-0070 I sampling date. As seen on Table 2, fecal coliform results for the downstream sampling location was clearly out of range with 37 colonies / 100 mL of water. The downstream median value for April 2007 was 110 colonies / 100 mL water. Only one of the five sampling dates,April 23, 2007,had acceptable fecal coliform values. 2.3 Storm Event Monitoring A representative storm event is defined as an event that measures greater than 0.1 inches of rainfall that is preceded by at least 72 hours during which no storm event measuring greater than 0.1 inches has occurred. According to the State Stormwater Management permit, each BMP must be-monitored during a representative storm event to demonstrate the efficiency of the practices (inflow/outflow). BMP samples must consist of a grab Isample of the first flush inflow and the discharge outflow. The first flush inflow sample window is within the first 30 minutes of a discernable inflow from a representative storm Ievent; the discharge outflow sample window is within the first 30 minutes of discharge from a representative storm event. The permit requires that this storm event monitoring be conducted quarterly (March, June, September, and December), and instream samples must also be collected during this event. On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate BUT sampling locations. Although four BMP structures exist at the Village at Mayfaire site, Wet Detention Pond 1, Wet Detention Pond 2, Wet Detention Pond 3, and Holding Pond 4, it will only be necessary to monitor the "outflow" structure for three of these areas. Holding Pond 4 does not have a typical "outflow" structure; the water in this pond is pumped to the other BMPs when Lthe level is high using a transfer pump. It will not be necessary to collect "outflow" samples from this location. Detention Pond 3 is comprised of 2 separate cells; the "inflow" sampling location has been designated as the structure where the west cell flows into the east (final) cell. MACTEC will collect the "outflow" samples from the outflow structure on each of the ponds by dipping a sample probe through the grate on the top of P:IProjectslCL1ENTYState Street(Village at Mayfaire)10uarterly Reportsl2007k2nd Quater 2007l2ndq&2007 report.doc 4 The Village at Mayfaire—Monitoring Services for Permit Compliance August 14,2007 (� MACTEC Project No.6550-03-0070 the outflow box at each of the ponds. The BMP monitoring locations are illustrated on r the attached Figure 2. r A rain gauge is located on the Village at Mayfaire site; this gauge is monitored after I storm events by MACTEC. On April 11, 2007,it began to rain over 0.1 inches (a total of 0.5 inches received by the morning of April 12, 2007) at the Mayfaire site; prior to this event, a measurable amount of rainfall (equal to or greater than 0.1 inches) had not been recorded since March 21, 2007 (0.1 inches). Samples were collected from the outflow structures at each of the four BMPs. Samples were collected from the inflow structures at r all four of the BMPs. MAC,TEC went to each of the pre-determined BMP and surface water sample locations, except for Howe Creek Upstream because it was dry at this time, and collected samples to be field analyzed for dissolved oxygen, temperature, conductivity, flow, and pH. Samples for total suspended solids, turbidity, and fecal coliform were collected in laboratory prepared bottles, placed in an ice-filled cooler, and hand-delivered to Environmental Chemists, Inc., in Wilmington, Nor la Carolina for f analysis. The field sampling worksheet and the laboratory analytical data for the storm monitoring event are included in Appendix C. The results of the sampling event are also listed in Table 3. { Water quality standards exist for the surface water samples collected from Howe Creek; however, no formal standards are established for the pond discharges. It should be noted that these ponds are used as a habitat by Canadian Geese and other waterfowl native to the site area; it is expected that fecal coliform readings will be significantly elevated in the ponds. l As illustrated on the tables,the results of the storm sampling event for April 11,2007 show the unnamed tributary of Howe Creek Downstream that i uns through the Mayfaire site to be out of compliance with the 15A NCAC 2B standards. Results for pH, fecal P:IProjectslCLIENTSLState Street(Village at May faire)lQuarterly Reports12007Und¢eater 2007l2nd qtr 2007 report.doc 5 I The Village at Mayfaire—Monitoring Services for Permit Compliance August 14,2007 rMACTEC Project No.6550-03-0070 I coliform, dissolved oxygen and turbidity for the Howe Creek downstream sampling location were all shown to be out of compliance. Since no sample was taken from the Howe Creek Upstream location,we can not conclude that a low dissolved oxygen level r may be naturally occurring for the area at this time. The fecal coliform results for Howe I Creek Downstream was 590 colonies/ 100 mL water,which is far above the standard of 14 colonies/ 100 mL water. r l I I { I I P:1ProjectslCL1ENTSIState Street(Village at Mayfaire)(Quarterly Reports1200712nd Quater 200712nd gtr 2007 report.doc 6 I {.

Unfortunately, your request cannot be granted at this time. The following information is required prior accepting your request to transfer the permit: 1. Please submit the transfer of ownership document with original signatures only. The document I received appears to have photocopied signatures, which cannot be accepted. If all parties need an original, please sign 3 original documents, keep one, return one to me and one to The Village at Mayfaire, LLC. 2. Please provide documentation of your status as the Vice President of the Association. This would be in the form of the minutes of a meeting of the Association wherein it has been documented that you are the duly elected Vice President of said Association. 3. Please submit a current Designer's Certification. The certification issued in 2004 was a partial certification only. A new certification, which addresses the partial items from 2004 as well as the other items, must be submitted. 4. The Operation and Maintenance plan included in your transfer package is not acceptable. I have attached copies of the permitted original supplement forms, which contain the specific design criteria and maintenance procedures for the infiltration basins that currently serve as the stormwater treatment devices for this project. Please sign, date, notarize and return the documents to the Division with an original signature. By copy of this letter to Michael Kavanaugh, I am informing him that the rules require a person to be at least the level of Vice President in order to sign any document associated with a permit, and that his signature can be accepted only if he provides a signed letter of authorization from a person of at least the level of Vice President in The Village at Mayfaire, LLC, authorizing him to sign the permit transfer request on their behalf. Additionally, please include documentation of the named Vice-President or President who signs the letter.

Five stations were sampled on January 24, 2006: two stations located at the Village at Mayfaire and three in the Mayfaire Town and Community Centers (Table 1, Figure 1). Table 1. Station Names and Numbers for Split Sampling Event at Mayfaire. Station Name Number Howe Creek Upstream (Village) 1 Howe Creek Downstream (Village) 2 Two Mile Branch 3 Howe Creek Upstream (Mayfaire) 4 Howe Creek Downstream (Mayfaire) 5 DWQ and MACTEC conducted field measurements concurrently and MACTEC staff collected water samples at all stations. Instream physical measurements taken were: temperature, dissolved oxygen, pH and conductivity. Samples were collected for fecal coliform bacteria, total suspended solids (TSS), and turbidity. The permit states a "split sampling" requirement for these projects. MACTEC provided sample bottles and all but the fecal coliform samples were collected in one container, mixed well and split into two separate containers. In order to follow sampling protocol and avoid possible contamination, fecal coliform samples were collected in individual bottles. Where there was sufficient flow, the fecal samples were collected concurrently. Where there was low flow, they were collected one after the other. All samples were analyzed by Environmental Chemists, Inc. laboratory in Wilmington. MACTEC and DWQ physical and chemical sampling results are summarized in Table 2. The relative percent difference (RPD) was calculated for the two data sets as a gross guideline for acceptable precision between data sets. Relative difference is used when comparing two "experimental quantities", neither of which is considered to be the "correct" value. Although there are no specific criteria for comparability of field duplicate analyses, a brief literature search indicated that a RPD of up to 25% may be acceptable for inorganics and other miscellaneous water quality parameters. Field measurements had an average RPD of 7%, which appears to be well within acceptable limits, particularly considering two different brand meters were used that were calibrated using different standards. The RPD for conductivity alone was considerably higher with 3 of the five samples being higher than 25%. This is likely a matter of difference between meters and not an issue of methodology. The average RIPD for collected samples was 12%, well within acceptability limits. In summary, the split sampling requirements were met for 2006 and overall, field measurements and sample results were well within acceptable limits.

Consistency Determination for Mayfaire I, LLC. New Hanover County, North Carolina 1. Background Mayfaire I, LLC and North Carolina Agricultural Foundation, Inc [College of Agriculture and Life Sciences, North Carolina State University (NC State)] propose to implement a management plan to create and maintain visibility over an approximate 1.4-acre site along Military Cutoff Road adjacent to Smokey Bones Restaurant at Mayfaire. The site currently obscures visibility between Military Cutoff Road and an unleased parcel west of the site. The marketability of this unleased parcel is the focus of the Purpose and Need. This is a revised formal request (original draft dated 30 June 2005) for permit modification of the Department of the Army Permit— ID 20000135 and 401 Water Quality Certification - #3341 based on agency comments received on 8 July (DCM), 12 July (COE, DWQ, and WRC) and 8 August 2005 (FWS). We request modification of Special Conditions P and T of the above referenced Department of the Army permit and Water Quality Certification. Special Condition P states: "The permittee and its contractors and/or agents shall not excavate, fill, or perform mechanized land clearing at any time in the construction or maintenance of this project within waters and/or wetlands, except as authorized by this permit, or any modification to this permit. There shall be no excavation from or waste disposal into jurisdictional wetlands or waters associated with this permit without appropriate modification of this permit." Special Condition T states: "The Permittee shall preserve and maintain the entire on-site mitigation area as described in the Mayfaire Compensatory Mitigation Plan. Except as specifically authorized by the Mayfaire Compensatory Mitigation Plan, the Permittee is prohibited from performing any of the following activities on the mitigation property: filling; grading; excavating; earth movement of any kind; construction of roads, walkways, buildings, signs, or any other structure; any activity that may alter the drainage patterns on the property; the destruction, mowing, or other alteration of vegetation on the property; disposal or storage of any garbage, trash, or other waste material; or any other activity which would result in the wetlands being adversely impacted or destroyed." The proposed modification requests a more active versus passive management approach to this site and will have multiple benefits that are mutually compatible. Acceptance of this proposed modification will result in the addition of 6.9 acres of upland buffer along Howe Creek into the permanent conservation easement in exchange for the removal of upper- and mid-story canopy on the 1.4-acre site. Mayfaire benefits with a more aesthetic appearance to their Military Cutoff Road frontage and increased site visibility to currently unleased parcels. Authorization of this permit modification will not affect the jurisdictional status or preservation/conservation status of the site and it will remain under management of NC State. The proposed 6.9-acre site to be added to the conservation easement represents Page 1 of 3 27 October 2005 forested land, portions of which are currently available for development. Compared to the 1.4-acre site proposed for modification, the 6.9 acres represents: 1) about five times the amount of area proposed for modification, 2) similar and/or better wildlife habitat, 3) a larger block of habitat that is contiguous with existing wetland (44+ acres) within the conservation easement, and 4) an area within Howe Creek drainage basin and in closer proximity to the water body. In addition to the proposed on-site mitigation, an additional acre of non-riparian hardwood wetlands will be restored at the off-site Taylor Farm in Pender County, NC. This will increase the amount of wetland mitigation occurring at this site for Mayfaire from 10.96 acres (authorized in the original permit/certification) to 11.96 acres. 2. Project The proposed project is described in the attached proposal titled "Proposal to Manage Vegetation on a 1.4-acre Site at Mayfaire, New Hanover County, North Carolina," dated September 2005, as sent to the US Army Corps of Engineers and copied to the NC Division of Coastal Management on 16 September 2005. This same proposal was also sent to the NC Division of Water Quality with a completed application (Engineer Form 4345) on 11 October 2005. 3. Areas of Environmental Concern (AECs) The project is located within the Howe Creek drainage basin in New Hanover County, NC. In order to assess whether the project required a CAMA Major Development Permit it was necessary to determine if the project impacted areas of environmental concern as defined in the North Carolina Administrative Code 15A NCAC07H. Although there are numerous AECs, the ones of most concern include coastal wetlands, estuarine waters, estuarine shorelines, and public trust areas. The Environmental Management Commission pursuant to T15A NCAC .021 B designates an additional are of concern as outstanding resource waters (ORW). The area proposed for vegetation maintenance occurs near a ditch that drains into Howe Creek, which is designated as an ORW, but the proposed activity is not within 575 feet of the ORW, and the proposed project will not directly impact waters of the State of North Carolina or ORW. Conclusion The proposed project is outside of any area of environmental concern. As defined in General Statute 113A-103(5)a, the project does not require authorization pursuant to the Coastal Area Management Act in that it will not occur in a duly designated area of environmental concern. 4. General Policy Guidelines The proposed project is consistent with,15A NCAC 07M General Policy Guidelines for Coastal Areas. More specifically, Section 7M.0200 Shoreline Erosion Policies are not germane to the topic because there is no proposed shoreline erosion control device proposed. Section 7M.0300 Shorefront Access Policies are not contravened because the proposed project will not impact current access to estuarine shoreline neighborhood Page 2 of 3 27 October 2005 access sites, regional access sites, rnulti-regional access sites, or other areas in which the public generally accesses the estuarine waters in this area. Section 7M.0306 Local Government and State Involvement have not identified this site with a plan to provide local access. Section 7M.0400 Coastal Energy Policies are not contravened because the proposed project does not involve the development of energy facilities or energy resources within the State. Section 7M.0500 Post-Disaster Policies are not applicable to the proposed activity. Section 7M.0600 Floating Structure Policies are not applicable to the proposed activity. Section 7M.0700 Mitigation Policies are addressed in conjunction with the proposed mitigation presented to the U.S. Army Corps of Engineers as compensation for any affects associated with the proposed activity. Therefore, the mitigation policies are consistent with the proposed plan for development. Section 7M.0800 Coastal Water Quality Policies will not be an issue since no fill or discharge is proposed to jurisdictional waters. Section 7M.0900 Policies and Use of Coastal Air Space are not applicable to the project. Section 7M.1000 Policies on Water and Wetland Based Target Areas for Military Training Activities are not applicable to the project. Section 7M.1100 Policies on the Beneficial Use and Availability of Materials Resulting from the Excavation or Maintenance of Navigational Channels are not applicable to the project. Section 7M.1200 Policies on Ocean Mining are not applicable to the project. Conclusion Based on the review of the General Policy Guidelines for Coastal Areas, the proposed project is consistent with T15A NCAC Subchapter 07M. 5. Land Use Plan Review Our initial review of the New Hanover County Land Use Plan does not reveal any inconsistency with the proposed project/activity. The latest 2005 draft Land Classification Map identifies the project area as "resource protection." The proposed project/activity a) does not propose any fill to jurisdictional wetlands or waters, b) does not increase in impervious surface, c) propose any change in the land use classification. Conclusion It is our determination that the proposed project is consistent with the New Hanover County Land Use Plan. 6. Project Consistency Conclusion These supporting documents, in accordance with 15 CFR 930.58 supply the data necessary to assess our conclusion that the project is consistent with the Federal Coastal Zone Management Act of 1972, as amended and the enforceable policies of the North Carolina approved Coastal Management Program. We request that the North Carolina Division of Coastal Management concur with our Consistency Certification that the proposed activity complies with the enforceable policies of the North Carolina Approved Management Program and will be conducted in a manner consistent with such Program.

Brooke Lamson, Corps of Engineers Noelle Lutheran,NC Division of Water Quality Joanne Steenhuis,NC Division of Water Quality Ron Sechler,National Marine Fisheries Service Becky Fox,Environmental Protection Agency Howard Hall,Fish and Wildlife Service Stephen Rynas,Division of Coastal Management Steve Everhart,Wildlife Resources Commission Joe Taylor, Murchison and Taylor Samuel Cooper,CZR Incorporated Jim Hudgens,CZR Incorporated William Hoffmann,NC State University Proposal to Manage Vegetation on a 1.4-Acre Site at Mayfaire, New Ilanover County, North Carolina Purpose and Need: Mayfaire I, LLC and North Carolina Agricultural foundation,Inc [College of Agriculture and Life Sciences, North Carolina State University (NC State)] propose to implement a management plan to create and maintain a visibility corridor over an approximate 1.4-acre site adjacent to Smokey Bones Restaurant at Mayfaire. The visibility corridor will be created by removing all trees and maintaining the shrub layer at 2 meters on the forested/shrub-scrub site. The site currently obscures visibility between Military Cutoff Road and an unleased parcel west of the site. The marketability of this unleased parcel is the focus of the Purpose and Need. The removal of trees will provide additional protection to surrounding and adjacent property. The maintenance of the 1.4-acre project area will remain under the management of NC State, as NC State owns the property in fee simple. Compensatory mitigation for the removal of trees and biannual maintenance of the shrub/scrub layer within the 1.4-acre project area will be the donation of an additional 6.9 acres of an on-site upland area within the watershed of Howe Creek into the existing conservation easement, dated 6 March 2003. This undivided upland parcel is available and suitable for development but will be preserved in its natural condition and restricted by the conditions of the permanent conservation easement and permit thereby protecting it from development. Request(Manalzement Plan): Mayfaire and NC State requests approval from the U.S. Army Corps of Engineers and N.C. Division of Water Quality to implement a management plan to create and maintain visibility over an approximate 1.4-acre site. This will be accomplished through tree removal and biannual maintenance of the shrub/scrub layer to 2 meters above existing ground level. The estimated number of trees to be removed is 141 hardwoods and 35 pine trees, for a total of 176 trees. Annual maintenance will involve the employment of mechanical and hand clearing methods. Vegetative debris will be removed from the site and no alteration to site topography or hydrology will occur in conjunction with the activity. The current condition of the forested/shrub-scrub site lacks a view corridor, preventing clear visibility to retail shops from the intersection of Destiny Way Drive and Military Cutoff Road. In exchange for tree removal and maintenance of shrubs of the 1.4 acre site, an additional 6.9 acres of on-site upland buffer within the Howe Creek watershed are offered. These areas will be donated and preserved in perpetuity in the existing conservation easement and remain subject to all conditions of the conservation easement. The conservation easement is partial mitigation for impacts authorized by Department of the Army permit, Action ID 200001359. Proposal 1 19 September 2005 Location: The 1.4-acre site proposed for modification is located south of the existing Smokey Bones restaurant and west of the intersection of Destiny Way Drive and Military Cutoff Road. The site is also adjacent to an unnamed tributary/drainage ditch to Howe Creek in New Hanover County,North Carolina(Figure 1). An undivided, 6.9-acre on-site upland buffer mitigation area,being proposed for donation into the conservation easement, is located along Howe Creek contiguous to the existing conservation easement and Area C, a wetland mitigation area (Figure 2). The site is located north of Howe Creek and borders the western boundary of Mayfaire property. Existing Site Conditions of 1.4-Acre Project Area: An evaluation of existing upland and wetland soils, vegetation, and hydrology of the 1.4- acre project area was conducted by CZR Incorporated to assist with management recommendations of the entire tract. The site is occupied by 1.10 acres of Section 404 jurisdictional wetland, and is characteristic of U.S. Fish and Wildlife's classification of palustrine forested/shrub scrub, needle leaved evergreen, seasonally flooded wetland (see photographs in Appendix A). The site vicinity prior to development scored 30.5 using the Division of Water Quality's (DWQ)wetland rating system (0-100 scale). Recent conditions still score the site under 40 using DWQ's rating system. Hydrology, monitored with five manual wells and a semi-continuous monitoring well from 18 February 2005 to 3 June 2005, has ranged from +2.5 to 36 inches below the surface; however, area rainfall was below average in February, March, and April, and slightly above average in May of 2005. Hydroperiods range from 8.2% to 15.6% based on New Hanover County's growing season of 27 February to 26 November(271 days). The site is nearly surrounded by impervious surface, several feet higher in elevation than the site. Elevations of the tract range from 22 to 25 feet,with the wettest portion in the northeast corner. The underlying soil is mapped as Murville fine sand, a mineral hydric soil. The texture, color, and depth of each soil horizon were described at each well location at the time of well installation(Table 1). Soils at the site were hydric loams, sands, or mucks. Existing dominant vegetation was characterized by herb, shrub, and tree species sampling and wetland indicator status designations. The most common species in the herb stratum are broom-sedge (Andropogon virginicus) (FAC-), red bay (Persea borbonia) (FACW), and yellow jessamine (Gelsemium sempervirens) (FAC). The project area has a well established shrub layer consisting of red maple (Acer rubrum) (FAC), loblolly pine (Pinus taeda) (FAC), red bay, gallberry (Ilex glabra) (FACW), yellow jessamine, and sweetgum (Liquidambar styraciflua) (FAC+). Tree species present are: red maple, red bay, loblolly pine, and sweetgum and range from 14 to 62 feet tall, and are mostly less than 30 years old(based on tree cores). The estimated number of trees is 141 hardwoods and 35 pine trees, for a total of 176 trees, with an average diameter at breast height of 5.4 inches and 6.2 inches,respectively. Proposal 2 19 September 2005 Historic Natural Conditions of 1..4-Acre Project Area: The historical natural condition of the project area was a non-riparian interstream wet flat underlain by hydric soil (Murville fine sand). The site appears to have been a pine flatwood community most recently with a. canopy of loblolly pine, pond pine (Pinus serotina), and possibly longleaf pine (Pinus palustris). Lack of fire has allowed the development of a thick shrub stratum. The project area was timbered by the previous owner prior to Mayfaire development. Proposed NUtigation Site Conditions: The proposed site for exchange totals 6.9 acres of upland buffer mitigation,which will be donated into the conservation easement (Figure 2). An evaluation of the site for dominant vegetation composition was conducted by CZR Incorporated on 12 September 2005 to assist in the comparative analysis of the vegetative composition of upper- and mid-story canopy (Table 2 and Appendix B). The site, ranges in elevation from 23 to 28 feet, and is underlain by Pamlico muck, Murville fine sand, and Leon sand. All three soil types characterize poorly drained hydric soils. Biotic communities range from mature mixed pine/hardwood forest, bay forest, to shrub/scrub. The native dominant canopy vegetation within the site consists of loblolly pine, pond pine, sweet bay magnolia (Magnolia virginiana), red maple, and water oak (Quercus nigra) (Appendix B, photographs). Tree species, based on field evaluations, range in age from 15 to 30 years. The shrub and herbaceous layer mainly consisted of gallberry, greenbrier (Smilax bona-nox), giant cane (Arundinaria gigantea), and fetterbush (Lyonia lucida). Highbush blueberry (Paccinium eorymbosum), bracken fern (Pteridium aquilinum), and cinnamon fern (Osmunda cinnamome) were also found occasionally in the herbaceous layer. Federally Protected Species Potentially occurring federally protected species within New Hanover County were addressed during the permitting phases of the Mayfaire project. Surveys for rough-leaved loosestrife (RLL) (Lysimachia asperulaefolia)were conducted during the permitting process and none were detected. The NC Natural Heritage Program database does not identify occurrence records for protected species near the project site. The proposed modification will not adversely affect any federally listed species. Proiect Summary: The maintenance and removal of the upper- and mid-story canopy within the 1.4-acre project area is not likely to adversely affect wetland functions, nor will wetland hydrology will be altered. Any affects of site maintenance will be mitigated with the protection and addition of 6.9 acres of land with similar vegetative characteristics near Howe Creek and in a more valuable landscape position. Mayfaire seeks to ensure that compensatory mitigation provide adequate replacement of habitat for wildlife resources. The 1.4-acre project area currently represents an "island," the product of a formerly larger system that has been fragmented by surrounding development. Due to isolation and Proposal 3 19 September 2005 fragmentation of the project area, an extensive "edge effect" has occurred. These edge effects are well known to decrease productivity of some sensitive wildlife, like neotropical migrant birds. Many neotropical migrants are area sensitive, requiring large blocks of habitat. The current 1..4-acre site represents a small island of habitat,unlikely to harbor area-sensitive species. This site is more likely to support species favoring ecotones, like brown-headed cowbirds (Molothrus ater),which are harmful to neotropical migrants. Residential or commercial development of the proposed 6.9-acre mitigation site would create an opening in the current forest canopy, increasing habitat degradation to adjacent areas by the introduction of fragmentation and edge-effects. Removal of vegetation and development of the 6.9-acre site would likely prove to be more detrimental to area-sensitive wildlife by fragmenting the landscape, compared to maintaining forest vegetation at the 1.4-acre site. The 1.4-acre site has a greater potential to provide other important wetland functions (compared to wildlife habitat), while the larger 6.9-acre site has a better opportunity to offer wildlife habitat and maintain/improve the habitat corridor along Howe Creek. Upland areas, bordering jurisdictional wetlands, often serve to filter, catch, and retain dissolved and suspended matter carried by surface runoff of water from surrounding landscapes. When an upland adjacent to a wetland is developed, sedimentation (the increase of deposited particulate matter) can become a major water quality problem for the wetland, as well as Howe Creek, classified as Outstanding Resource Waters. However, the upland vegetation is particularly effective at controlling sedimentation and turbidity (particulate matter suspended in water). Preserving wetland and upland within the drainage basin is important to protecting water quality in wetlands, in the groundwater, and in downstream coastal waters. The preservation of an additional 6.9 acres of upland buffer will provide replacement mitigation with similar species composition and underlying hydric soils. These areas provide an extension of approximately 500 feet of upland buffer adjacent to riparian jurisdictional wetlands along Howe Creek as well as serve as a corridor to existing contiguous interstream wetlands (over 44 acres). The cover types present in the buffer zone, including early successional pine forest, bay forest, and mature mixed pine-hardwood forest, provide a diversity of habitat for wildlife species. The wider buffer zone would contribute to the protection of Howe Creek's water quality.

The permit for the Village at Mayfaire was issued December 4, 2002, permit number SW8 011119; this permit is set to expire December 4, 2012. Monitoring requirements are outlined in Section III of the permit, and include the following elements: ➢ Semiannual scheduled inspections (every 6 months) by a Professional Engineer (P.E.) to assure that the permitted stormwater system functions at optimum efficiency. These records must indicate the date, activity, name of person performing the work and what actions were taken. These inspections are scheduled to occur during June and December of each year. ➢ Instream analytical monitoring shall be conducted quarterly, concurrent with documentation of a system inspection. The collected samples are to be analyzed for total suspended solids, turbidity and fecal coliform by a certified analytical lab; the samples are to be field analyzed by MACTEC for dissolved oxygen, temperature, conductivity, flow, and pH. ➢ Instream storm event monitoring is required during four representative storm events in each year of the permit. Each BMP at the Village at Mayfaire site; three wet detention storage ponds, shall be monitored concurrently with the instream storm event monitoring (4 events per year). Grab samples shall be obtained at specified locations in the BMP to demonstrate the efficiency of the practices (inflow/outflow). The collected samples are to be analyzed for total suspended solids, turbidity and fecal coliform by a certified analytical lab; the samples are to be field analyzed by MACTEC for dissolved oxygen, temperature, conductivity, flow and pH. ➢ One instream analytical monitoring event per year will be "split" with the DWQ. The samples will be delivered to a State-certified lab. Since flow and temperature samples cannot be split, they will be excluded from the split sample requirement. The split sampling event is scheduled to occur during the first quarter of each year.

Semiannual scheduled inspections are required to be performed by a Professional Engineer (P.E.) every six months to assure that the permitted stormwater system at the Village at Mayfaire site functions at optimum efficiency. These inspections are scheduled to occur during June and December of each year. There was no inspection conducted by a P.E. during this quarter. 2.2 Instream Analytical Monitoring Instream analytical monitoring is required to be conducted quarterly, concurrent with documentation of a system inspection. Two surface water monitoring sites have been selected after negotiation with the DWQ. On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate surface water monitoring locations. Two surface water monitoring sites have been selected on the unnamed tributary of Howe Creek that runs through the site; one upstream and one downstream of the Village at Mayfaire site. The surface water monitoring locations are illustrated on the attached Figures 1 and 2. Latitude and longitude coordinates were obtained in the field by MACTEC on December 8, 2004. These coordinates are included on Figures 1 and 2. On September 7, 2005, MACTEC went to the Village at Mayfaire site to conduct the instream analytical monitoring event for the third quarter of 2005. MACTEC went to each of the two pre-determined surface water sample locations and attempted to collect samples to be field analyzed for dissolved oxygen, temperature, conductivity, flow, and pH; and laboratory analyzed for total suspended solids,turbidity, and fecal coliform. The field sampling worksheet and the laboratory analytical data for the instream analytical monitoring event are included in Appendix A. The results of the sampling event are also listed in Table 1. G:clientslstate streeAquarterly reports13rd0200513rd02005.doe 2 The Village at Mayfaire—Monitoring Services for Permit Compliance October 24,2005 MACTEC Project No. 6550-03-0070 2.3 Instream Analytical Monitoring Results The classifications assigned to the waters of the State of North Carolina are based upon existing or contemplated best usage of the various streams and segments of streams in the basin determined through studies and evaluations and the holding of public hearing for consideration of the classifications. According to 15A NCAC 02B .0311, Howe Creek is considered a class SA Outstanding Resource Water (SA ORW) from its source to the Intracoastal Waterway. In Howe Creek, the fecal coliform standard is based on the median value of five readings in a 30-day period; the median value is not to exceed 14 colonies per 100 mL of water. The table showing all results of all fecal coliform sampling for September is attached as Table 2; the laboratory analytical results for the additional fecal coliform sampling events are included in Appendix B. According to 15A NCAC 02B .0220 "violations of the fecal coliform standard are expected during rainfall events and, in some cases, this violation is expected to be caused by uncontrollable nonpoint source pollution" Due to the low amounts of rainfall and the hot summer temperatures leading up to this event, there was no water present at the upstream or downstream sampling locations of the unnamed tributary of Howe Creek that runs through the Village site. Therefore, it was not possible to collect water samples or take field readings from these locations during the instream sampling event for September 2005. 2.4 Storm Event Monitoring A representative storm event is defined as an event that measures greater than 0.1 inches of rainfall that is preceded by at least 72 hours during which no storm event measuring greater than 0.1 inches has occurred. According to the State Stormwater Management permit, each BMP must be monitored during a representative storm event to demonstrate the efficiency of the practices (inflow/outflow). BMP samples must consist of a grab sample of the first flush inflow and the discharge outflow. The first flush inflow sample window is within the first 30 minutes of a discernable inflow from a representative storm event; the discharge outflow sample window is within the first 30 minutes of discharge from a representative storm event. The permit requires that this storm event monitoring be conducted quarterly, and instream samples must also be collected during this event. G:clientsWate streetlquarterly reports Ord0200513rdQ2005.doe 3 The Village at Mayfaire—Monitoring Services for Permit Compliance October 24,2005 MACTEC Project No.6550-03-0070 On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate BMP sampling locations. Although four BMP structures exist at the Village at Mayfaire site, Wet Detention Pond 1, Wet Detention Pond 2, Wet Detention Pond 3, and Holding Pond 4, it will only be necessary to monitor the"outflow" structure for three of these areas. Holding Pond 4 does not have a typical "outflow" structure; the water in this pond is pumped to the other BMPs when the level is high using a transfer pump. It will not be necessary to collect "outflow" samples from this location. Detention Pond 3 is comprised of 2 separate cells; the "inflow" sampling location has been designated as the structure where the west cell flows into the east (final) cell. MACTEC will collect the "outflow" samples from the outflow structure on each of the ponds by dipping a sample probe through the grate on the top of the outflow box at each of the ponds. The BMP monitoring locations are illustrated on the attached Figure 2. A rain gauge is located on the Village at Mayfaire site, and this gauge is monitored daily, when rain events occur, by MACTEC. On August 23, 2005, 1.9 inches of rain were received at the Village. Prior to this event a measurable amount of rainfall greater than 0.1 inches had not been recorded since August 17, 2005 (0.8 inches). Samples were collected from the inflow structures at each of the four BMPs and at the outflow structure for Pond 3. Due to the low amounts of rainfall and the hot summer temperatures leading up to this event, there was no water present at the upstream sampling location of the unnamed tributary of Howe Creek that runs through the Village site. Therefore, it was not possible to collect water samples or take field readings from this location during the storm sampling event for August 2005. Pond 4's outflow was not sampled because when the water level is high, it is pumped to another pond. MACTEC personnel went to each of the pre-determined BMP and surface water sampling locations and collected samples to be field analyzed for dissolved oxygen, temperature, conductivity, flow, and pH where possible. Samples for total suspended solids, turbidity, and fecal coliform were collected in laboratory prepared bottles, placed in an ice-filled cooler, and hand-delivered to Environmental Chemists, Inc., in Wilmington,North Carolina for analysis. The field sampling worksheet and the laboratory analytical data for the storm monitoring event are included in Appendix C. The results of the sampling event are also listed in Table 3. G:clientsWate stree6quarterly reports OrdO2005 BrdO2005.doc 4 The Village at Mayfaire—Monitoring Services for Permit Compliance October 24,2005 MACTEC Project No. 6550-03-0070 2.5 Storm Event Monitoring Results Water quality standards exist for the surface water samples collected from Howe Creek; however, no formal standards are established for the pond discharges. It should be noted that these ponds are used as a habitat by Canadian Geese and other waterfowl native to the site area; it is expected that fecal coliform readings will be elevated in the ponds. The data in Table 3 indicates that total suspended solids, turbidity, conductivity, dissolved oxygen, and temperature measurements were very similar when comparing the Detention Pond 3 inflow data point to the outflow data point. An increase in fecal coliform was reported by the laboratory for the Detention Pond 3 inflow and outflow data points. The dissolved oxygen levels are above the established standard in every sample. The pH values of the BMP samples were elevated compared to the standard range except for the value at the Howe Creek Downstream, which was within the standard range. Due to low or no water levels in the unnamed tributary of Howe Creek that runs through the Village site, it was not possible to collect water samples from the upstream sampling location very many times in the third quarter of 2005. Water levels were also very low at the downstream location during the third quarter. Therefore, it was not possible to collect five samples during the month of August for the upstream location, and many samples from the downstream location came nearly from the bed of the creek. Every effort was made to collect each sample with sufficient water for analysis while at the same time trying not to stir up the bed of the creek. Based on the limited samples taken and the circumstances under which they were collected (i.e. low water levels), it is difficult to compare the results to the standards for this quarter. 3.0 FUTURE WORK MACTEC's next quarterly sampling events for the Village at Mayfaire are scheduled for the fourth quarter of 2005, October through December.

The permit for the Village at Mayfaire was issued December 4, 2002, permit number SW8 011119; this permit is set to expire December 4, 2012. Monitoring requirements are outlined in Section III of the permit, and include the following elements: 1 ➢ Semiannual scheduled inspections (every 6 months) by a Professional Engineer ( (P.E.) to assure that the permitted stormwater system functions at optimum t efficiency. These records must indicate the date, activity, name of person performing the work and what actions were taken. These inspections are scheduled to occur during the June and December sampling events. ➢ Instream analytical monitoring shall be conducted quarterly (March, June, September, and December), concurrent with documentation of a system inspection. The collected samples are to be analyzed for total suspended solids, turbidity and fecal coliform by a certified analytical lab; the samples are to be ffield analyzed by MACTEC for dissolved oxygen, temperature, conductivity, C flow, and pH. ➢ Instream monitoring is required during four representative storm events in each year of the permit. Each BMP at the Village at Mayfaire site; three wet detention storage ponds, shall be monitored concurrently with the instream storm event fmonitoring (4 events per year). Grab samples shall be obtained at specified locations in the BMP to demonstrate the efficiency of the practices L (inflow/outflow). The collected samples are to be analyzed for total suspended solids, turbidity and fecal coliform by a certified analytical lab; the samples are I to be field analyzed by MACTEC for dissolved oxygen, temperature, t . conductivity, flow and pH. L > One sample event per year will be "split" with the DWQ. The samples will be delivered to a State-certified lab. Since flow and temperature samples cannot be LGxlientsWate stree6quarterly reports Vune05Vune05.doc I L The Village at Mayfaire—Monitoring Services for Permit Compliance August 21,2005 MACTEC Project No. 6550-03-0070 split, they will be excluded from the split sample requirement. The split sample event is scheduled to occur during the March sampling event. 2.0 THE VILLAGE AT MAYFAIRE This section presents the results from field activities and laboratory analysis for the Village at Mayfaire site. S2.1 Semiannual Inspection by a P.E. Semiannual scheduled inspections are required to be performed by a Professional Engineer (P.E.) every six months to assure that the permitted stormwater system at the Village at Mayfaire site functions at optimum efficiency. These inspections are scheduled 1 to occur during the June and December sampling events. On July 6, 2005, Daniel C. Shields, a licensed Professional Engineer in the state of North Carolina, went to the Village at Mayfaire site to conduct an inspection of the stormwater system in operation at the site. During this inspection, the system was observed to be operating as intended and i no maintenance or corrections were necessary at this time. 0 E 2.2 Instream Analytical Monitoring Instream analytical monitoring is required to be conducted quarterly, concurrent with documentation of a system inspection. Two surface water monitoring sites have been selected after negotiation with the DWQ. On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate surface water monitoring locations. Two surface water monitoring sites have been selected on the unnamed tributaryof Howe Creek that runs through the site; one upstream and one g � p downstream of the Village at Mayfaire site. The surface water monitoring locations are illustrated on the attached Figures 1 and 2. Latitude and longitude coordinates were fobtained in the field by MACTEC on December 8, 2004. These coordinates are included l on Figures 1 and 2. LG:clientslstate streetlyuarterly reports Uune05Uune05.doc 2 ( The Village at Mayfaire—Monitoring Services for Permit Compliance August 21,2005 MACTEC Project No. 6550-03-0070 On June 2, 2005, MACTEC went to the Village at Mayfaire site to conduct the instream analytical monitoring event for the second quarter of 2005. MACTEC went to each of the two pre-determined surface water sample locations and collected samples to be field I analyzed for dissolved oxygen, temperature, conductivity, flow, and pH. Samples for total suspended solids, turbidity, and fecal coliform were collected in laboratory prepared bottles, placed in an ice-filled cooler, and hand-delivered to Environmental Chemists, Inc., in Wilmington,North Carolina for analysis. fThe field sampling worksheet and the laboratory analytical data for the instream analytical monitoring event are included in Appendix A. The results of the sampling r event are also listed in Table 1. The classifications assigned to the waters of the State of North Carolina are based upon existing or contemplated best usage of the various streams and segments of streams in the basin determined through studies and evaluations and the holding of public hearing for consideration of the classifications. According to 15A NCAC 02B .0311, Howe Creek is considered a class SA Outstanding Resource Water (SA ORW) from its source to the Intracoastal Waterway. In Howe Creek, the fecal coliform standard is based on the median value of five readings in a 30-day period; the median value is not to exceed 14 colonies per 100 mI of water. The table showing all results of all fecal coliform sampling for June is attached as Table 2; the laboratory analytical results for the additional fecal coliform sampling events are included in Appendix B. According to 15A NCAC 02B .0220 "violations of the fecal coliform standard are expected during rainfall events and, in some cases, this violation is expected to be caused by uncontrollable nonpoint source pollution" L. As illustrated on the tables, the results of the instream sampling event for June 2005 show Lthe unnamed tributary of Howe Creek that runs through the Mayfaire site to be in compliance with the 15A NCAC 2B standards, with a few exceptions. Turbidity readings were in compliance at the upstream sampling location, but above the standard at the GxlientsWate streetlquarterly reportsVune05l1une05.doc 3 L ( The Village at Mayfaire—Monitoring Services for Permit Compliance August 21,2005 IMACTEC Project No.6550-03-0070 downstream sampling location. There was a petroleum sheen detected on the surface of the water on June 2, 2005 when the water samples were obtained. The higher turbidity reading may have been a result of the same sediment generating activity as the sheen. Dissolved oxygen readings were in compliance at both sampling locations. The downstream sampling location had a pH value slightly below acceptable levels, but since a lower value was also seen in the upstream sample, they may be assumed to be naturally occurring. Fecal coliform results for both the upstream and downstream sampling I locations were above the standard of 14 colonies/100 mL of water. The upstream sampling location had a higher median value than the downstream sampling location, so this violation should not be attributed to the Village at Mayfaire site. 2.3 Storm Event Monitoring A representative storm event is defined as an event that measures greater than 0.1 inches of rainfall that is preceded by at least 72 hours during which no storm event measuring greater than 0.1 inches has occurred. According to the State Stormwater Management j permit, each BMP must be monitored during a representative storm event to demonstrate ( the efficiency of the practices (inflow/outflow). BMP samples must consist of a grab 1 sample of the first flush inflow and the discharge outflow. The first flush inflow sample window is within the first 30 minutes of a discernable inflow from a representative storm event; the discharge outflow sample window is within the first 30 minutes of discharge from a representative storm event. The permit requires that this storm event monitoring be conducted quarterly, and instream samples must also be collected during this event. 1 On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC - representative in the field to select appropriate BMP sam lin locations. Although four psampling g LBMP structures exist at the Village at Mayfaire site, Wet Detention Pond 1, Wet Detention Pond 2, Wet Detention Pond 3, and Holding Pond 4, it will only be necessary Lto monitor the "outflow" structure for three of these areas. Holding Pond 4 does not have a typical "outflow" structure; the water in this pond is pumped to the other BMPs when Lthe level is high using a transfer pump. It will not be necessary to collect "outflow" LGxlientsWate streehquarterly reports Uune05Uune05.doc 4 L The Village at Mayfaire—Monitoring Services for Permit Compliance August 21,2005 MACTEC Project No.6550-03-0070 i- samples from this location. Detention Pond 3 is comprised of 2 separate cells; the "inflow" sampling location has been designated as the structure where the west cell flows into the east (final) cell. MACTEC will collect the "outflow" samples from the outflow structure on each of the ponds by dipping a sample probe through the grate on the top of f.. the outflow box at each of the ponds. The BMP monitoring locations are illustrated on the attached Figure 2. A rain gauge is located on the Village at Mayfaire site, and this gauge is monitored daily by MACTEC. On July 21, 2005, 0.1 inches of rain were received at the Village. Prior to this event a measurable amount of rainfall greater than 0.1 inches had not been recorded fsince July 14, 2005 (0.6 inches). Samples were collected from the inflow structures at each of the four BMPs and at the outflow structure for Pond 3. Due to the low water I levels in Ponds 1 and 2, no discernable outflow was observed following the 0.1 inches of rainfall. Also, due to the low amounts of rainfall and the hot summer temperatures I leading up to this event, there was no water present at the upstream sampling location and not enough present at the downstream sampling location to collect samples or to take readings. Pond 4's outflow was not sampled because it is a pumped to another pond. 1 I According to the stormwater permit, the storm event should measure greater than 0.1 inches of rainfall and should occur during each quarter of the year. However, due the dry l - weather during the month of June, a representative storm event did not occur during June. Therefore, the earliest weekday when a representative storm event occurred after not raining more than 0.1 inches in the 72 hours prior, was July 21, 2005. The summer weather pattern was a forecast for isolated showers, usually late in the afternoon with unpredictable amounts of rainfall expected. The MACTEC representative elected to Lsample on this storm event in order to obtain samples that fit as closely to the permit's specifications. L L LG:clientsWate streetlquarterly reports Uune05Uune05.doc 5 L r The Village at Mayfaire—Monitoring Services for Permit Compliance August 21, 2005 MACTEC Project No, 6550-03-0070 MACTEC personnel went to each of the pre-determined BMP and surface water sampling locations and collected samples to be field analyzed for dissolved oxygen, temperature, conductivity, flow, and pH where possible. Samples for total suspended solids, turbidity, and fecal coliform were collected in laboratory prepared bottles, placed r in an ice-filled cooler, and hand-delivered to Environmental Chemists, Inc., in Wilmington,North Carolina for analysis. The field sampling worksheet and the laboratory analytical data for the storm monitoring event are included in Appendix C. The results of the sampling event are also listed in Table 3. F 2.4 Monitoring Results Water quality standards exist for the surface water samples collected from Howe Creek; however, no formal standards are established for the pond discharges. It should be noted that these ponds are used as a habitat by Canadian Geese and other waterfowl native to the site area; it is expected that fecal coliform readings will be elevated in the ponds. The data in Table 3 indicates that fecal coliform and conductivity measurements were the same when comparing the Detention Pond 3 inflow data point to the outflow data point. Slight increases in total suspended solids and turbidity values were reported by the laboratory for the Detention Pond 3 inflow and outflow data points. The dissolved oxygen levels in the Pond 3 Outflow and Pond 4 Inflow samples are slightly lower than the established standard. The pH values of the samples were within the standard range except for the value at the Pond 3 Inflow, which was slightly above the standard range. Due to low to no water in the unnamed tributary of Howe Creek that runs through the LVillage site, it was not possible to collect water samples during the storm sampling event for July 2005. Because fecal coliform samples were taken at these sites during the month I of June, fecal values were able to be reported for this quarter. Fecal coliform results for L both the upstream and downstream sampling locations were above the standard of 14 colonies/100 mL of water. The upstream sampling location had a higher median value LG•clientsWate streeAquarterly reportsVune05Uune05.doc 6 L The Village at Mayfaire—Monitoring Services for Permit Compliance August 21,2005 MACTEC Project No.6550-03-0070 than the downstream sampling location, so this violation should not be attributed to the Village at Mayfaire site. 3.0 CONCLUSION Due to staff changes and the unpredictability of rain events MACTEC was unable to g p Y conduct stormwater sampling during the second quarter of 2005 in June. The stormwater sampling was instead conducted in July 2005, as close to the second quarter timing as the weather would allow, and was included in this report for the second quarter(except for the fecal coliform values for the stream samples where June data was used). This July data(with the exception of the fecal coliform values from the stream samples)will not be taken into account for the third quarter report. MACTEC will conduct the stormwater jsampling event again during the existing third quarter ending in September,but not in July. Since there are no specific instructions in the permit as to the exact months in which the quarterly storm sampling event must take place, MACTEC will attempt to conduct the storm event sampling during the first months of each quarter rather than the 1 last, allowing three months in which to conduct the storm event sampling. i l . 1 _ L L L LG:clientsWate streetlquarterly reportsVune05Vune05.doc 7 L Tables b L C v tn LJO kn.

Five stations were sampled on March 17, 2005: two stations located at the Village at Mayfaire and three in the Mayfaire Town and Community Centers (Table 1, Figure 1). Table 1. Station Names and Numbers for Split Sampling Event at Mayfaire: Station Name Number Howe Creek Upstream (Village) 1 Howe Creek Downstream (Village) 2 Two Mile Branch 3 Howe Creek Upstream (Mayfaire) 4 Howe Creek Downstream (Mayfaire) 5 Instream physical measurements taken were: temperature, dissolved oxygen, pH and conductivity. Samples were collected for fecal coliform bacteria, total suspended solids (TSS), and turbidity. While the permit states a "split sampling" requirement for these projects, samples were not collected in a single container and then split into two containers during this sampling event. DWQ accompanied MACTEC staff and conducted field measurements and sample collection at the same locations, generally within five minutes of each other. DWQ fecal coliform samples and all MACTEC samples were analyzed by Environmental Chemists, Inc. laboratory in Wilmington. DWQ TSS and turbidity samples were shipped overnight by courier and analyzed by the state laboratory in Raleigh. MACTEC and DWQ physical and chemical sampling results are summarized in Table 2. The relative percent difference (RPD) was calculated for the two data sets as a gross guideline for acceptable precision between data sets. Relative difference is used when comparing two "experimental quantities", neither of which is considered to be the "correct" value. Although there are no specific criteria for comparability of field duplicate analyses, a brief literature search indicated that a RPD of up to 25% may be acceptable for inorganics and other miscellaneous water quality parameters. Field measurements had an average RPD of 9%, which appears to be well within acceptable limits, particularly considering two different brand meters were used that were calibrated using different standards. The average RPD for collected samples was considerably higher, at 65%. The high rate of difference between samples is not believed to be a matter of sample collection, handling, or analysis error, but more likely a matter of natural variability within the creeks. Samples were collected within five minutes of each other and distribution of sediment, particulates, and bacteria is not uniform within any water body. Also, DWQ TSS and turbidity samples were not processed the same day of collection, although they were analyzed within the proper holding time. From a QA/QC perspective, MACTEC followed standard operating procedures in the field. If the intent is to determine analysis differences, conducting actual "split sampling" may be conducted next year. ❑ r r "I: r N C o o C?

I can't remember the name. It is across from St. Andrews Episcopal Church on Oleander/Military Cutoff Rd. right beyond the intersection of Wrightsville Avenue headed north. The building address is now 1650 Military Cutoff Road, lot 1, R05616-003-006-000. It was built by Wrightsville Builders several years ago who is also Tri Coast Properties. The new parking lot appears to have a connection to the permitted sites parking lot. This parking lot is also next to Unique Landscapes office. I haven't seen a revised permit on this new parking lot and its less than an acre. But if its attached to the previously permitted site I think it is phased development. If you can think of the name please let me know. If not I think I am going to call Wrightsville Builders and ask them what they know about this parking lots connection to their old project. I also have a question about the Villages at Mayfaire. All their ponds have pumps that send water to a vegetated filter which rises up and then drains into an infiltration area on the south side of the site. This may be for the City but I thought it might be part of the State stormwater plan to keep water from leaving the site. If its for the state, could the developer put a sump pump in the vegetated filter and pump that standing water into an irrigation system INSIDE the infiltration area to keep the vegetated filter dry when its not raining? The problem per the developer is that the water breeds bugs etc. and I can't get grass to grow and stay alive when the vegetated filter is under water most of the time.

The permit for the Village at Mayfaire was issued December 4, 2002, permit number SW8 011119; this permit is set to expire December 4, 2012. Monitoring requirements are outlined in Section III of the permit, and include the following elements: ➢ Semiannual scheduled inspections (every 6 months) by a Professional Engineer (P.E.) to assure that the permitted stormwater system functions at optimum efficiency. These records must indicate the date, activity, name of person performing the work and what actions were taken. These inspections are scheduled to occur during the June and December sampling events. ➢ Instream analytical monitoring shall be conducted quarterly (March, June, September, and December), concurrent with documentation of a system inspection. The collected samples are to be analyzed for total suspended solids, turbidity and fecal coliform by a certified analytical lab; the samples are to be field analyzed by MACTEC for dissolved oxygen, temperature, conductivity, flow and pH. ➢ Instream monitoring is required during four representative storm events in each year of the permit. Each BMP at the Village at Mayfaire site; three wet detention storage ponds, shall be monitored concurrently with the instream storm event monitoring (4 events per year). Grab samples shall be obtained at specified locations in the BMP to demonstrate the efficiency of the practices (inflow/outflow). The collected samples are to be analyzed for total suspended solids, turbidity and fecal conform by a certified analytical iab; the samples are to be field analyzed by MACTEC for dissolved oxygen, temperature, conductivity, flow and pH. ➢ One sample event per year will be "split" with the DWQ. The samples will be delivered to a State-certified lab; since flow and temperature samples G:clientslstate stree6quarterly reportsW3-05Vmar05.doc I The Village at Mayfaire—Monitoring Servicesfor Permit Compliance April21,2005 MACTEC Project No.6550-03-0070 cannot be split, they will be excluded from the split sample requirement. The split sample event is scheduled to occur during the March sampling event. 2.0 THE VILLAGE AT MAYFAIRE This section presents the results from field activities and laboratory analysis for the Village at Mayfaire site. 2.1 Semiannual Inspection by a P.E. Semiannual scheduled inspections are required to be performed by a Professional Engineer (P.E.) every six months to assure that the permitted stormwater system at the Village at Mayfaire site functions at optimum efficiency. These inspections are scheduled to occur during the June and December sampling events. No inspection was performed by a P.E. during the first quarter of 2005. 2.2 Instream Analytical Monitoring Instream analytical monitoring is required to be conducted quarterly, concurrent with documentation of a system inspection. Two surface water monitoring sites have been selected after negotiation with the DWQ. On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate surface water monitoring locations. Two surface water monitoring sites have been selected on the unnamed tributary of Howe Creek that runs through the site; one upstream and one downstream of the Village at Mayfaire site. The surface water monitoring locations are illustrated on the attached Figures 1 and 2. Latitude and longitude coordinates were obtained in the field by MACTEC on December 8, 2004; these coordinates are included on Figure 2. On March 17, 2005, MACTEC went to the Village at Mayfaire site to conduct the instream analytical monitoring event for the first quarter of 2005; Stephanie Garrett of the DWQ accompanied MACTEC in the field and collected duplicate samples to satisfy the GxlientsWate stree6quarterly reports W3-051mar05.doc 2 The Village at Mayfaire—Monitoring Services for Permit Compliance April 21,2005 MACTEC Project No. 6550-03-0070 "split" sample event for 2005. MACTEC went to each of the two pre-determined surface water sample locations, and collected samples to be field analyzed for dissolved oxygen, temperature, conductivity, flow and pH. Samples for total suspended solids, turbidity, and fecal coliform were collected in laboratory prepared bottles, placed in an ice-filled cooler, and hand-delivered to Environmental Chemists, Inc., in Wilmington, North Carolina for analysis. The field sampling worksheet and the laboratory analytical data for the instream analytical monitoring event are included in Appendix A. The results of the sampling event are also listed in Table 1. The classifications assigned to the waters of the State of North Carolina are based upon existing or contemplated best usage of the various streams and segments of streams in the basin determined through studies and evaluations and the holding of public hearing for consideration of the classifications. According to 15A NCAC 02B .0311, Howe Creek is considered a class SA Outstanding Resource Water (SA ORW) from its source to the Intracoastal Waterway. In Howe Creek, the fecal coliform standard is based on the median value of five readings in a 30-day period; the median value is not to exceed 14 colonies per 100 mL of water. The table showing all results of all fecal coliform sampling for March is attached as Table 2; the laboratory analytical results for the additional fecal coliform sampling events are included in Appendix B. According to 15A NCAC 02B .0220 "violations of the fecal coliform standard are expected during rainfall events and, in some cases, this violation is expected to be caused by uncontrollable nonpoint source pollution" As illustrated on the tables, the results of the surface water sampling event for March 2005 show the unnamed tributary of Howe Creek that runs through the Mayfaire site to be in compliance with the 15A NCAC 2B standards, with only a few exceptions. Turbidity readings were in compliance at the upstream sampling location, but above the standard at the downstream sampling location. Very low flow was experienced at the GxlientsWate street lquarterly reportsW3-051mar05.doe 3 The Village at Mayfaire—Monitoring Services for Permit Compliance April 21,2005 MACTEC Project No. 6550-03-0070 downstream sampling location during this sampling event; this may have contributed to the high turbidity readings. Dissolved oxygen readings were in compliance at both sampling locations. The Howe Creek Downstream sampling location had pH values slightly below the acceptable levels; however, this is a violation that was also seen in the upstream sample, and may be assumed to be naturally occurring. Fecal coliform results for both the upstream and downstream sampling locations were above the standard of 14 colonies / 100 mL of water. The upstream sampling location had a higher median value than the downstream sampling location, so this violation should not be attributed to the Village at Mayfaire site. 2.3 Storm Event Monitoring A representative storm event is defined as an event that measures greater than 0.1 inches of rainfall that is preceded by at least 72 hours during which no storm event measuring greater than 0.1 inches has occurred. According to the State Stormwater Management permit, each BMP must be monitored during a representative storm event to demonstrate the efficiency of the practices (inflow/outflow). BMP samples must consist of a grab sample of the first flush inflow and the discharge outflow. The first flush inflow sample window is within the first 30 minutes of a discernable inflow from a representative storm event; the discharge outflow sample window is within the first 30 minutes of discharge from a representative storm event. The permit requires that this storm event monitoring be conducted quarterly (March, June, September, and December), and instream samples must also be collected during this event. On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate BMP sampling locations. Although four BMP structures exist at the Village at Mayfaire site, Wet Detention Pond 1, Wet Detention Pond 2, Wet Detention Pond 3, and Holding Pond 4, it will only be necessary to monitor the "outflow" structure for three of these areas. Holding Pond 4 does not have a typical "outflow" structure; the water in this pond is pumped to the other BMPs when the level is high using a transfer pump. It will not be necessary to collect "outflow" GxlientsWate stree6quarterly reportsW3-051mar05.doc 4 The Village at Mayfaire—Monitoring Services for Permit Compliance April 21,2005 MACTEC Project No.6550-03-0070 samples from this location. Detention Pond 3 is comprised of 2 separate cells; the "inflow" sampling location has been designated as the structure where the west cell flows into the east (final) cell. MACTEC will collect the "outflow" samples from the outflow structure on each of the ponds by dipping a sample probe through the grate on the top of the outflow box at each of the ponds. The BMP monitoring locations are illustrated on the attached Figure 2. A rain gauge is located on the Village at Mayfaire site; this gauge is monitored daily by MACTEC. On March 23, 2005, 0.7 inches of rain were received at the Village at Mayfaire site; prior to this event a measurable amount of rainfall (greater than 0.1 inches) had not been recorded since March 19, 2005 (0.3 inches). Samples were collected from the inflow structures at each of the four BMPs, at the outflow structure for Pond 1 and Pond 3, and at each of the two surface water sampling locations. Due to the low water level in Pond 2, no discernable outflow was observed following the 0.7 inches of rainfall. MACTEC went to each of the pre-determined BMP and surface water sample locations, and collected samples to be field analyzed for dissolved oxygen, temperature, conductivity, flow and pH. Samples for total suspended solids, turbidity, and fecal coliform were collected in laboratory prepared bottles, placed in an ice-filled cooler, and hand-delivered to Environmental Chemists, Inc., in Wilmington, North Carolina for analysis. The field sampling worksheet and the laboratory analytical data for the storm monitoring event are included in Appendix C. The results of the sampling event are also listed in Table 3. Water quality standards exist for the surface water samples collected from Howe Creek; however, no formal standards are established for the pond discharges. It should be noted that these ponds are used as a habitat by Canadian Geese and other waterfowl native to the site area; it is expected that fecal coliform readings will be significantly elevated in the ponds. The data in Table 3 illustrates a slight decrease in fecal coliform and G:clientsWate stree6quarterly reportsW3-051mar05.doe 5 The Village at Mayfaire—Monitoring Services for Permit Compliance April 21,2005 MACTEC Project No. 6550-03-0070 conductivity when comparing the Detention Pond 1 inflow data point to the outflow data point. A decrease in total suspended solids, turbidity, and fecal coliform values has been reported by the laboratory for the Detention Pond 3 inflow and outflow data points. As illustrated on the tables, the results of the storm sampling event for March 2005 show the unnamed tributary of Howe Creek that runs through the Mayfaire site to be in compliance with the 15A NCAC 2B standards, with only a few exceptions. The dissolved oxygen levels in the Howe Creek Upstream sample are slightly lower than the established standard; however, since this sample is collected from a location upstream of the Mayfaire site, this dissolved oxygen level may be naturally occurring for the area. Finally, as discussed previously, fecal coliform results for both the upstream and downstream sampling locations were above the standard of 14 colonies / 100 mL of water. The upstream sampling location had a higher median value than the downstream sampling location, so this violation should not be attributed to the Village at Mayfaire site.

Monitoring requirements are outlined in Section III of the permit, and include the following elements: ➢ Semiannual scheduled inspections (every 6 months) by a Professional Engineer (P.E.) to assure that the permitted stormwater system functions at Coptimum efficiency. These records must indicate the date, activity, name of person performing the work and what actions were taken. These inspections are scheduled to occur during the June and December sampling events. instream analytical monitoring snail be conducted quarterly (March, June, September, and December), concurrent with documentation of a system f inspection. The collected samples are to be analyzed for total suspended i solids, turbidity and fecal coliform by a certified analytical lab; the samples are to be field analyzed by MACTEC for dissolved oxygen, temperature, conductivity,flow and pH. ➢ Instream monitoring is required during four representative storm events in each year of the permit. Each BMP at the Village at Mayfaire site; three wet Idetention storage ponds, shall be monitored concurrently with the instream storm event monitoring(4 events per year). Grab samples shall be obtained at specified locations in the BMP to demonstrate the efficiency of the practices (inflow/outflow). The collected samples are to be analyzed for total Lsuspended solids,turbidity and fecal coliform by a certified analytical lab; the samples are to be field analyzed by MACTEC for dissolved oxygen, Ltemperature, conductivity, flow and pH. ➢ One sample event per year will be "split" with the DWQ. The samples will be delivered to a State-certified lab; since flow and temperature samples LGxlientslstatestreeAquarterlyreports112-041dec04.doc I The Village at Mayfaire—Monitoring Services for Permit Compliance February 24,2005 MACTEC Project No.6550-03-0070 cannot be split,they will be excluded from the split sample requirement. The split sample event is scheduled to occur during the March sampling event. 2.0 THE VILLAGE AT MAYFAIRE This section presents the results from field activities and laboratory analysis for the Village at Mayfaire site. 2.1 Semiannual Inspection by a P.E. On December 8, 2004, Daniel C. Shields, a licensed Professional Engineer in the state of North Carolina, went to the Village at Mayfaire site to conduct an inspection of the stormwater system in operation at the site. During this inspection, the system was observed to be operating as intended and no maintenance or corrections were necessary at this time. 2.2 Instream Analytical Monitoring Instream analytical monitoring is required to be conducted quarterly, concurrent with documentation of a system inspection. Two surface water monitoring sites have been selected after negotiation with the DWQ. On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate surface water monitoring locations. Two surface water monitoring sites have been selected on the unnamed tributary of Howe Creek that runs through the site; one upstream and one Idownstream of the Village at Mayfaire site. The surface water monitoring locations are illustrated on the attached Figures 1 and 2. Latitude and longitude coordinates were obtained in the field by MACTEC on December 8, 2004; these coordinates are included in Table 1. Photographs of the surface water sampling locations are included in Appendix A. LOn December 10, 2004, MACTEC went to the Village at Mayfaire site to conduct the instream analytical monitoring event for the fourth quarter of 2004. MACTEC went to LGxlienW state streetlquarterly reportsU2-04Wec04.doc 2 The'Village at Mayfaire—Monitoring Services for Permit Compliance February 24,2005 MACTEC Project No.6550-03-0070 the two pre-determined surface water sample locations, and collected samples to be field analyzed for dissolved oxygen,temperature, conductivity, flow and pH. Samples for total suspended solids, fi_rbidity, and fecal colifo. .=sere c^llected in laboratory prepared bottles, placed in an ice-filled cooler, and hand-delivered to Environmental Chemists, Inc., in Wilmington,North Carolina for analysis. The field sampling worksheet and the laboratory analytical data for the instream analytical monitoring event are included in Appendix B. The results of the sampling event are also listed in Table 2. I The classifications assigned to the waters of the State of North Carolina are based upon existing or contemplated best usage of the various streams and segments of streams in the basin determined through studies and evaluations and the holding of public hearing for i consideration of the classifications. According to 15A NCAC 02B .0311, Howe Creek is considered a class SA Outstanding Resource Water (SA ORW) from its source to the Intracoastal Waterway. In Howe Creek, the fecal coliform standard is based on the median value of five readings in a 30-day period; the median value is not to exceed 14 colonies per 100 mL of water. The table showing all results of all fecal coliform sampling for December is attached as Table 3; the laboratory analytical results for the additional fecal coliform sampling events are included in Appendix C. According to 15A NCAC 02B .0220 "violations of the fecal coliform standard are expected during rainfall events and, in some cases, this violation is expected to be caused by uncontrollable nonpoint source pollution" As illustrated on the tables, the results of the surface water sampling event for December 2004 show the unnamed tributary of Howe Creek that runs through the Mayfaire site to be in compliance with the 15A NCAC 2B standards, with only a few exceptions. Turbidity readings were in compliance at both sampling locations; dissolved oxygen readings were in compliance at the downstream sampling location. The Howe Creek I Upstream sampling location had dissolved oxygen and pH values slightly below the L. Gxlienislstate streehquarterly reports112-041dec04.doc 3 I The Village at Mayfaire—Monitoring Services for Permit Compliance Fehmary 24,2005 ` MACTEC Project No.6550-03-0070 acceptable levels; however, since this sampling location is upstream of the Ma sire P g P Yf f development, these conditions can be assumed to be naturally occurring. The Howe Creek Downstream sampling location had pH values slightly below the acceptable levels; (� however, this is a violation that was also seen in the upstream sample, and may be I assumed to be naturally occurring. ecal coilforin results for both the upstream and downstream sampling locations were above the standard of 14 colonies / 100 mL of water. The upstream sampling location had a higher median value than the downstream sampling location, so this violation should not be attributed to the Village at Mayfaire site. E 2.3 Storm Event Monitoring f A representative storm event is defined as an event that measures greater than 0.1 inches of rainfall that is preceded by at least 72 hours during which no storm event measuring greater than 0.1 inches has occurred. According to the State Stormwater Management permit, each BMP must be monitored during a representative storm event to demonstrate the efficiency of the practices (inflow/outflow). BUT samples must consist of.a grab sample of the first flush inflow and the discharge outflow. The first flush inflow sample window is within the first 30 minutes of a discernable inflow from a representative storm event; the discharge outflow sample window is within the first 30 minutes of discharge from a representative storm event. The permit requires that this storm event monitoring i be conducted quarterly (March, June, September, and December), and instream samples must also be collected during this event. I On December 7, 2004, Stephanie Garrett of the DWQ accompanied a MACTEC representative in the field to select appropriate BMP sampling locations. Although four BMP structures exist at the Village at Mayfaire site, Wet Detention Pond 1, Wet Detention Pond 2, Wet Detention Pond 3, and Holding Pond 4, it will only be necessary to monitor the "outflow" structure for three of these areas. Holding Pond 4 does not have a typical "outflow" structure; the water in this pond is pumped to the other BMPs when the level is high using a transfer pump. It will not be necessary to collect "outflow" i L LG:clientslstate streetlquarterly reports112-041dec04.doc 4 The Village at Mayfaire—Monitoring Services for Permit Compliance February 24,2005 MACTEC Project No.6550-03-0070 samples from this location. Detention Pond 3 is comprised of 2 separate cells; the "inflow" sampling location has been designated as the structure where the west cell flows into t—be east (final) cell. I ACTFC will collect the samples from the outflav: structure on each of the ponds by dipping a sample probe through the grate on the top of the outflow box at each of the ponds. The BMP monitoring locations are illustrated on the attached Figure 2. Latitude and longitude coordinates were obtained in the field by MACTEC on December 8, 2004; these coordinates are included in Table 1. Photographs fof the BMP sampling locations are included in Appendix A. A rain gauge is located on the Village at Mayfaire site; this gauge is monitored daily by MACTEC. On December 9, 2004, a rain event began at 0845; prior to this event a measurable amount of rainfall (greater than 0.1 inches) had not been recorded since November 30, 2004 (0.4 inches). MACTEC went to the Village at Mayfaire site on December 9, 2004 at 1000 in anticipation of the rain event; this event measured 0.2 inches. Samples were collected from the inflow structures at three of the BMPs (the water level in Holding Pond 4 was not high enough to collect a sample), and at each of the two surface water sampling locations. Due to the low water levels in each of the three ponds, no discernable outflow was observed following the 0.2 inches of rainfall. MACTEC went to each of the pre-determined BMP and surface water-sample locations, and collected samples to be field analyzed for dissolved oxygen, temperature, conductivity, flow and pH. Samples for total suspended solids, turbidity, and fecal coliform were collected in laboratory prepared bottles, placed in an ice-filled cooler, and Ihand-delivered to Environmental Chemists, Inc., in Wilmington, North Carolina for analysis. l The field sampling worksheet and the laboratory analytical data for the storm monitoring levent are included in Appendix D. The results of the sampling event are also listed in Table 4. L L LGxlientslstatestreetlquarterlyreportsU2-041dec04.doc 5 The Village at Mayfaire—Monitoring Services for Permit Compliance February 24,2005 MAC=Project No.6550-03-0070 Water quality standards exist for the surface water samples collected from Howe Creek; however, no formal standards are established for the pond discharges. It should be noted that. these ponds are. used as a habitat by Canadian Geese and other =.�aterfo•.�l ^.ati.ye tc the site area; it is expected that fecal coliform readings will be significantly elevated in the ponds. As illustrated on the tables, pH levels for both surface water sampling points are below the 15A NCAC 2B standard. Since these levels are low both upstream and downstream of the Mayfaire site, it may be assumed that low pH levels are naturally occurring for the area. The dissolved oxygen levels in the Howe Creek Upstream sample are slightly lower than the established standard; however, since this sample is collected from a location upstream of the Mayfaire site, this dissolved oxygen level may be naturally occurring for f the area. Finally, as discussed previously, fecal coliform results for both the upstream I and downstream sampling locations were above the standard of 14 colonies / 100 mL of water. The upstream sampling location had a higher median value than the downstream sampling location, so this violation should not be attributed to the Village at Mayfaire site. l L_ C:clientslstate streeAquarterly reportsV2-04Wec04.doc 6 i i i i i i i i 1 Table 1 Locations for Sampling Points The Village at Mayfaire Wilmington,New Hanover County,North Carolina MACTEC Job No. 6550-04-0186 Sample Point Last Longitude Accuracy Howe Creek Upstream N 34014.9791 W 7r 49.8361 +/-15 feet � I Howe Creek Downstream ( N 34014.8991 I W 7r 49.7911 I +/-37 feet A I I Detention Pond 1-INFLOW N 34014.9941 W 776 49.8001 +/-15 feet 1V Detention Pond 1-OUTFLOW N 34014.9691 W 7r 49.8151 +/-21 feet i Detention.Pond 2-INFLOW I N 34015.1371 I W 77°49.704' I +/-25 feet Detention Pond 2-OUTFLOW N 34015.1051 1 W 7r 49.664' I +A 10.6 feet Detention Pond 3-INFLOW N 34014.8781 l W 770 49.6851 +/-15 feet Detention Pond 3-OUTFLOW N 34014.8631 W 770 49.6551 +/-13 feet 1 ' A, . ..._ k Detention Pond 4-INFLOW N 34014.9711 W 7r 49.6501 +/-10 feet Notes: k Location information was obtained using a hand-held GPS unit.

SW8 010512, 011119, and 030701 Wilmington, New Hanover County, North Carolina Dear Ms. Theodorson; Our office received your letters dated November 11, 2004 and would like to address the questions you raised in your correspondence and during our site visit today regarding the monitoring requirements for the aforementioned stormwater permits. • Per our discussion today, BMP grab samples will be collected at the inflow and outflow structures during representative storm events. If there is no outlet structure, only the inlet will be sampled unless the storm event is severe enough that there is a discharge from the overflow. If there is not an above ground outlet pipe, samples are to be taken in the overflow structure by removing the grate on top of the box. • Ms. Linda Lewis has provided clarification regarding the inflow and outflow sample sites for Pond# 3 along Military Cutoff. The two forebay ponds and the pond adjacent to Michael's are considered to be one treatment system (BMP). As such, the 'butfall" structure of the forebay area at the north end of the three ponds is essentially the point at which the two ponds flow into the pond adjacent to Michael's Crafts. Consequently, this location would be considered the inflow location. The outflow site would be at the outfall structure in the pond next to Michael's. These locations will replace the stations we discussed this afternoon • The previous consultant collected their instream fecal samples in accordance with the State standard of five samples within 30 days. It is this office's preference that you continue to follow this methodology until such time as the Mayfaire development is "built out". A reevaluation can be made once development is complete and all appropriate land surfaces have been stabilized. Weekly samples are recommended, although you may need to double up for the month of December due to the timing of this response. N.C.Division of Water Quality 127 Cardinal Drive Extension (910)395-3900 Wilmington Regional office Wilmington,NC 28405 (910)350-2004(fax) Page 2of2 t MACTEC December 6,2004 • There are a variety of techniques and equipment available to measure stream flow and it is assumed by our office that you will employ an accurate method. • WIRO staff will accompany you during your first set of split samples and one set of the samples will be sent to a laboratory designated by WI RO staff. • There are no monitoring requirements for the Mayfaire Community Center(SW8 030701). • It is not necessary for you to sample standing water in the infiltration basins. Please provide our office with copies of the site plans indicating sample site locations, as well as the latitude and longitude of each. Once the station location maps are received, we will provide a final review on the sampling sites and make any adjustments as needed. I hope this addresses your questions regarding the monitoring at Mayfaire. Please feel free to contact me or Rick Shiver, SWP Regional Supervisor at (910) 395-3900 with any additional questions.

Bradley and Ken, if you see anything outrageously wrong, please advise ASAP. Linda Stephanie Garrett wrote: Per the questions from MACTEC,the consultant who will be handling inspections and monitoring at Mayfaire(SW8 010512) -please see if you can help me answer the following or forwardto the appropriate party for response. The consultant wants to begin their quarterly sampling this month so needs answers to at least the first question ASAP. 1. Evidently because the fecal standard is based on 5 samples in 30 days, the previous consultant was collecting 5 fecal samples over the month they were conducting their quarterly sampling. I don't see any language in the permit that dictated they do that. Had they been instructed to do so, and if so, is there a hard copy we can have for the files? The new consultant wants to know if they should be collecting fecal samples in the same manner so as to determine whether or not the instream samples are meeting State Standards, or if they only need a total of 8 fecal samples each year(i.e. the quarterly requirement and the representative storm event requirement) *I remember telling them to do 8 samples per year,but cannot find any documentation. As we discussed, Rick has suggested continuing with the 5 samples in 30 days, as is the standard,until construction is complete. We will then entertain a request from the permittee to change this requirement,based on results. * 2. The permit states that "the permitee shall split samples w/DWQ for at least one sample event per year". Does this mean I make a site visit w/them and we both collect samples or do they just collect two sets of samples and send one set to a certified lab we designate? *Generally, on those occasions where split samples are being done,the permittee would make arrangements ahead of time to collect double samples and send one set to our designated lab. For the Mayfaire permit, as we discussed, it would be preferable if DWQ collected its own split samples the first time, and then allowed the permittee to collect the split samples if the first round came out close.* 3. Some of the ponds at the Village don't have outlet structures; they are pumped to adjacent ponds 1 of 2 12/6/2004 4r54 PM RP:Mayfaire questions on an "as needed" basis. For their monitoring requirements do they only sample the inflow? Do they sample the pumped "outflow" even though it may not be an immediate result of a storm event and not necessarily done during the time of their storm event sampling? *The ponds at the Village (SW8 011119) act as storage areas only. The runoff from the ponds is pumped to the,infiltration basins at a specified rate equal to about a 4 day drawdown in the pond. The pumped runoff is then allowed to infiltrate, so there shouldn't be any discharge to grab a sample of for rainfall events of 2"-3". For larger storm events,runoff may overtop the outlet structure in the pond and flow into the vegetated filter. At those times a sample of the overflow may be taken. The fact that there is no discharge in response to the design storm is evidence of "the efficiency of the practice." Apparently there are no monitoring requirements for the Mayfaire Community Center site(SW8 030701) -the consultant requested confirmation that no monitoring is needed at this site. *No monitoring requirements were placed into the SW8 030701 permit.* Thanks so much!

The classification of thev!receiving stream, should this system ever overflow and engage the vegetated filter, is 8A ORW. This classification means that proposed measures to protect water quality need to be designed and installed to a higher degree of accuracy and quality, not wedged in to the point that they don't function as they were intended to function. Please relocate the vegetated filter for Pond 1. Perhaps another, more suitable location is necessary where the space to construct a functional vegetated filter is available.

Project Name: The Village at Mayfaire Project Number: SW8 011119 Control Measure: Infiltration Basin Water Body: Howe Creek Classification: SA ORW Directions to site, address: off Military Cutoff Road, adjacent Mayfaire 2. Inspection Date: May 11, 2004 Weather Conditions: warm and sunny 3. Compliance Issues: Y N ® ❑ The drainage area (including offsite) and built-upon area to the permitted system are per the approved plan. ® ❑ All the built-upon area associated with the project is graded such that the runoff drains to the system. ❑ ® For ponds/infiltration, the outlet/bypass structure relative elevations are per the approved plan. (Must be verified via as-built survey if in question). ❑ ® The inlets and outlet structure are located'perthe approved plans and do not cause short-circuiting. ❑ ® A trash rack is provided over the outlet weir and orifice. ❑ ® All slopes are grassed with permanent vegetation and are not eroding. ® ❑ Vegetated slopes are no steeper than 3:1. ❑ ® Required drawdown devices are correctly sized per the approved plans. ❑ ® All required parts of the system are provided, such as a vegetated shelf, and a forebay. ❑ ® The designer's certification has been submitted. ® ❑ The built-upon area dimensions are per the approved plan. 4. Required Actions: (Each deficiency is explained below and what needs to be done to bring the system back into compliance) a. The outlet structures for Ponds 1 and 2 are missing. Please install immediately. Pond 1 is in the second-most active construction area on the project, and it needs to be fully functional in order to treat the runoff. b. The location of a previously unknown stream immediately adjacent Pond 1 will make location of the required vegetated filter difficult. Please submit revised plans to show this stream, with the required vegetated filter also located. Upon approval, please install the filter. C. The pump for Pond 3 has not been installed. The Pond 3 watershed is the largest and contains the majority of the current construction. The runoff from Pond 3 must be pumped to the infiltration area for disposal. Only overflow in excess of the permitted storage volume is allowed to bypass the pond via the vegetated filter prior to entering the upstream waters of Howe Creek. d. The slopes of all three ponds need attention. Please repair the eroded areas of the slopes and stabilize with the permanent grass cover indicated on the approved stormwater plans. e. The vegetated filter for Pond 2 has not been installed. f. The bottom and sides of the vegetated filter for Pond 3 need to be stabilized with permanent vegetation, per the approved plans. g. Please submit interim designees certifications for each pond to assure that the basic requirements of the permit are being met in the ponds.

W:21."iuuvv2i County,North C aroiina Wbw ,a MACTEC Project 6550-03-0070 Dear Mr. Shiver and Ms.Wetherill: MACTEC Engineering and Consulting, Inc. (MACTEC) respectfully submits this letter of introduction and request for assistance to determine sample locations for The Village at Mayfaire site, located on Military Cutoff Road in Wilmington,North Carolina. State Street Construction Company (State Street) has selected MACTEC to assist them in complying with the necessary monitoring requirements for their Permit for a Land Disturbing Activity, their State Stormwater Management Permit, and their National Pollutant Discharge Elimination System (NPDES) General Permit for The Village at Mayfaire site. MACTEC intends to work closely with the North Carolina Department of Environment and Natural Resources Division of Water Quality (DWQ) and the New Hanover County Engineering Department (NHC) in this effort, so that all necessary permit requirements are satisfied to your approval. During the current phase of construction, MACTEC is assisting State Street by conducting weekly(more frequent when storm events of greater than 0.5 inches of rain occur)inspections of the erosion and sedimentation control facilities at the site. MACTEC is completing the attached checklist following the inspection, and working with State Street to correct any problems that are found. Based on review of the State Stormwater Management Permit No. SW8 011119, Section III. Monitoring Requirements, 1. "Instream analytical monitoring shall be conducted quarterly, concurrent with documentation of a system inspection. In addition, instream monitoring shall be MACTEC Engineering and Consulting,Inc. 5710 OLEANDER DRIVE,SUITE 110•WILMINGTON,NC 28403 910-452-1185•Fax:910-791-1338 The Village at Mayfaire—Monitoring Services for Stormwater Permit Compliance September 17,2003 MACTEC Project No.6550-03-0070 Page 2 required during four representative storm events in each year of the permit. Monitoring sites shall be selected both upstream and downstream of the project site on Howe Creek. Monitoring sites shall be selected by agreement between the permittee and the DWQ." MACTEC request your assistance in dctermining monitoring locations on Howe Creek. MACTEC proposes to select two monitoring locations upstream, and two monitoring locations downstream of The Village at Mayfaire site. MACTEC also requests your assistance in determining when the monitoring of these sites should begin; based on language in the permit, MACTEC assumes that the monitoring should begin on-ce the stormwater management system is constructed in it's entirety, vegetated and operational, however, it may be useful in the future to collect background samples from the instream monitoring locations,prior to the completion of the stormwater management system. Based on review of Section Ill. Monitoring Requirements, 2. "Each BMP shall be monitored. The sample locations will be determined by agreement of the permittee and the Division." As of the date of this letter, State Street has not completed construction of any of the BMPs; however, MACTEC would also like clarification and assistance in determining the sampling locations for the BMPs. MACTEC appreciates your assistance in determining the instream and BMP sampling locations for The Village at Mayfaire site, and looks forward to working with you on this project. Please contact either Dan Shields or Kristina Theodorson at (910) 452-1185 to further discuss these matters. Sincerely, MACTEC ENGINEERING AND CONSULTING,INC. M & Kristina A. Theodorson Daniel C.
