Suite 105 Post Office Box 2469 Shailotte. North Carolina 28459 Office: 910-754-8029 Firm License Number: C-3014 Ward Mine Brunswick County, North Carolina Evaluation of Requirements for Operation and Monitoring Plan and Stormwater Pollution and Prevention Plan NPDES General Permit NCG020000 January 2010 Introduction - An Operation and Monitoring; Plan.. when required, is site specific for each mine even though many components of the various Stormwater Best Management Practices (BMPs) that can be utilized from different projects may be similar. The implementations of Stormwater Best Management Practices are utilized to develop a Stormwater Pollution and Prevention Plan (SPPP). The intent of this document is to discuss each BMP or O & M plan component that must be utilized for this particular mine site. The goal is to identify and provide all measures necessary to assure the protections of any nearby wetlands and water quality. Compliance with Part II Section A: Requirements to Construct New or Expanding Treatment Facilities - Since the proposed Ward Mine will not utilize a process recycle wastewater system. an Authorization to Construct will not be necessary and the permittee will not be required to meet the requirements for operation of such a treatment facility per Part I1 Section A nor will the permitee be required to meet the requirements for Part II Section B. Compliance with Section A Part III: Monitoring, Controls, and Limitations for Permitted Discharges - Section A of Part III requires the permittee to develop and implement a Stormwater Pollution and Prevention Plan (SPPP). This requires a written plan that can be easily followed, understood or implemented by mine employees. The Stormwater Pollution and Prevention Plan for this project is included herein as Exhibit A. The SPPP addresses items I through 6 in Section A of Part III and also follows as closely as possible the Table of Contents provided in the permit in order to assure that all areas of concern have been addressed. The SPPP includes a thorough inspection and maintenance plan, recommended preventative maintenance and good housekeeping measures. spill control and cleanup measures; stormwater management requirements as well as the requirement that all temporary and permanent erosion and sedimentation control measures that are either required within the mining permit or shown on the mining plan approved by the Division of Land Resources be implemented in accordance with the permit and/or approved plan. Compliance with Section B Part III: Stormwater Discharges: Analvtical Monitoring Requirements — Section B of Part III defines stormwater discharges as stormwater from mining activity areas, including, but not limited to, areas of mine excavations, other land disturbance, process areas and vehicle maintenance. This section does not apply to wastewater discharges from mine dewatering and process areas. It shall be noted that analytical monitoring is not required for any basin or pond designed to contain the 25- year, 24-hour storm without discharging, and that can regain capacity to hold such and event within 5 days' time through means other than discharging to surface waters. A basin or pond that meets this provision is considered a non -discharging stormwater C VI-1 control. This mine will not contain anv stormwater bypass structures, it has been determined that the mine excavation area will easily contain the 25-year. 24-hour storm"' without allowing any discharge. According to the National Resources Conservation Service (NRCS), the 25-year, 24-hour storm for Brunswick County yields 8.8-inches of rainfall while the 100-year, 24-hour storm yield 10 inches of rainfall. The supporting documentation and calculations demonstrating that the mine excavation area will contalr not only the 25-year, 24-hour storm but even the 100-year, 24-hour storm is included in the attached Exhibit B. Compliance with Section C Part III: On -Site Vehicle Maintenance Monitoring Requirements (Stormwater Discharges) — This section of the permit requires that facilities that have any on -site vehicle maintenance activity that uses more than 55 gallons of new motor oil per month when averaged over the calendar year shall perform analytical monitoring. There will be no vehicle maintenance will on this site. Any maintenance performed on vehicles used in the removal or transport of any source material from the property will be performed at off -site shop locations. Compliance with Section D Part III: Qualitative Monitoring Requirements (Stormwater Discharges) —This section of the permit requires that a visual inspection of each Stormwater outfall regardless of representative outfall status and shall be performed as listed within Table 6. Qualitative Monitoring Requirements. Since no stormwater outfall is necessary for this project as discussed in the Compliance with Section B Part III above, compliance with this section of the permit is not necessary. Compliance with Section E Part III: Effluent Limitations and Monitoring Requirements for Mine Dewatering Wastewater and Process Wastewater - This section of the permit also requires the permittee to provide a Pumping Operation and Monitoring (O&M) flan for mine dewatering activities that have the potential to drain wetlands or other surface waters. Since it has been determined that the subject property does not contain any wetlands or other surface waters, a determination of the proximity to any nearby wetlands -and surface waters on adjacent properties within the radius of influence was also necessary, According to the Brunswick County wetland inventorv. no wetlands or other surface waters are located within 1600 feet of -the proposed mine. The , _ property is located within a rural area of managed pineland forest with pine flats within close proximity The radius_of_influence for this project has been determined to extend approximately 300_feet from the. -ultimate —excavation —area. Therefore, it can be reasonably anticipated that no wetlands will have the potential to be drained as a result of infrequent dewatering activities that will be utilized by this particular project. The calculations and supporting documentation used in this evaluation is included in the attached Exhibit C. In addition; hydraulic calculations and other supporting documentation related to proposed dewatering activities is included within the attached Exhibit D. The mine owner will engage a contractor to utilize a pump with sufficient capacity to drain the excavation area in order to begin intermittent excavation activities. After initial drawdown, smaller groundwater control "maintenance" pumps will be used to maintain a semi-dry condition while any excavation activities occur. During testing procedures that were necessary to estimate the withdrawal rate (less than 10,000 gpd), the exceptional clarity of the discharge water both being pumped into the stilling basin as well as that exiting the stilling basin. This can be attributed to the fact that the pump discharge location is a substantial distance from any remaining excavation area. Prior to initiation of the pumping drawdown testing procedures that were performed, as well as during the entire test period, the clarity of the water within the excavation area as well as the pumped discharge remained exceptional. If desired, grab samples could be obtained during the performance of any pumping activities in order to determine discharge characteristics such as Settleable Solids, Total Suspended Solids or Turbidity. It is estimated that the stilling basin will have to accommodate a flowrate of less than 15,0 gallons per minute in order to maintain a semi -dry condition during the performance of intermittent excavation activities. It is our opinion that benchmark values of 0.1 ml/l for Settleable Solids, 100 mgll for Total Suspended Solids and 50 NTU for Turbidity will not be exceeded by the proposed dewatering activities related to this project. It should be noted that there will not be any p ocessing of any mine material that will occur on this site. This particular mine has been approved by Brunswick County as a Class I Mine, which does not allow the processing of materials on -site. Brunswick County allows processing of material on -site only for mines that are classified as Class 11 Mines. East Coast Engineering & Surveying, P.C. Appendix A Stormwater Pollution and Prevention Plan Ward Mine Brunswick County North Carolina Fxhihif A Ward Mine Brunswick County, NC Stormwater Pollution and Prevention Plan 1. Site Plan. The site plan shall provide a description of the physical facility and the potential pollutant sources that may be expected to contribute to contamination of stormwater discharges. The site plan shall contain the following: (a) A general location map (USGS quadrangle map or appropriately drafted equivalent map), showing the facility's location in relation to transportation routes and surface waters, the name of the receiving water(s) to which the stormwater outfall(s) discharges, or if the discharge is to a municipal separate storm sewer system, the name of the municipality and the ultimate receiving waters, and accurate latitude and longitude of the point(s) of discharge. The general location map (or alternatively the site map) shall identify whether each receiving water is impaired (on the state's 303(d) list of impaired waters) or is located in a watershed for which a TMDL has been established, and what the parameter(s) of concern are. A topoquad map has been included and identifies the site by latitude and longitude. The receiving waters are not listed in the state's 300(d) v list of impaired waters and is not located in a TMDL watershed. (b) A narrative description of storage practices, loading and unloading activities, outdoor process areas, dust or particulate generating or control processes, and waste disposal practices. A narrative description of the potential pollutants that could be expected to be present in the stormwater discharge from each outfall. The mine will be operated as a sand pit. There will be no process, unloading, dust or particulate generating activities on the site. There will be no pollutant generating,activities at the site. The site will be operated strictly as a source site for fill dirt to be used on other sites. (c) A site map drawn at a scale sufficient to clearly depict: the site property boundary, the stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial activity areas (including storage of materials, disposal areas, process areas, loading and unloading areas, and haul roads), site topography, all drainage features and structures, drainage areas for each outfall, direction of flow in each drainage area, industrial activities occurring in each drainage area, buildings, existing BMPs (with design capacities), and permanent impervious surfaces, such as roads or process areas that are unlikely to change frequently. The site map shall include a distance legend. In addition, the following industrial activity areas most also be identified on the site map: fueling, engine maintenance and repair, vessel maintenance and repair, washing, painting, sanding, blasting, welding, and metal fabrication. A site map including all applicable items listed above has been included with this submittal. There will be no fueling, or vehicle/machinery maintenance on the site. (d) A list of significant spills or leaks of pollutants that have occurred during the previous three (3) years and any corrective actions taken to mitigate spill impacts. There have been no significant spills or leaks on the site. (e) Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. The certification statement will be signed in accordance with the requirements found in Part IV, Standard Conditions, Section B, Paragraph 5. The permittee shall re -certify annually that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. The certification has been included with this submittal and the permittee has been informed of the requirement of the annual re- certification for non-stormwater discharges. 2. Erosion and Sedimentation Control. The permittee shall implement the management practices and the erosion and sedimentation control measures that are included in the mining permit or erosion and sedimentation control permit issued by the Division of Land Resources (DLR). Compliance with the DLR issued permit is considered a requirement of this general permit. Any deviation from the DLR issued permit, or amendments to the issued permit, that impacts water quality shall constitute a violation of the terms and conditions of this general permit. All erosion and sediment controls shall be inspected, and a respective written record of repairs and maintenance shall be available to DWQ inspectors. A signed copy of the issued permit including the approved erosion and sedimentation control measures and the reclamation plan shall be maintained on the site at all times. Once an area is released by the Division of Land Resources in accordance with NC G. S. Chapter 74, Article 7, it shall no longer be subject to this general permit. The mining plan for this project has been prepared and submitted to NCDENR — Land Quality Section — Division of Land Resources (DLR) for approval. A copy of the.mining permit will be submitted to the NCDWQ upon issuance by the DLR. . 3. Stormwater Management Plan.The stormwater management plan shall contain a narrative description of the materials management practices employed which control or minimize the exposure of significant materials to stormwater, including structural and nonstructural measures. The stormwater management plan, at a minimum, shall incorporate the following. - (a) Management of Stor�mwa, ter Runoff and Runon. The permittee shall maintain stormwater BMPs for mine excavation and disturbance areas, process areas, and any other areas associated with mining or vehicle maintenance activities. In addition, controls should be used to limit or isolate selected land disturbance and process areas and limit the amount of off site stormwater runon to those areas. Appropriate Best Management Practices (BMPs) should be used to divert, infiltrate, reuse or otherwise manage stormwater runoff and runon in a manner that reduces pollutants in stormwater discharges leaving the site. Appropriate BMPs may include but are not limited to: vegetative swales, berms, use of reclaimed mine areas, and reuse of collected stormwater (such as for an industrial process or as an irrigation source). The static water table elevation has been observed to be approx. 61.0' MSL and the elevation of the top of the mine pit has been measure to be approx. 65.0' MSL. The 100 year rain event produces 10 inches of - rainfall in a 24 hour period per the Brunswick County NRCS Storm Data. This will cause a 0.83 foot rise in elevation. The mine pit j�iut SW7 provides storage in excess of the 100 year storm event and as such t ,�,,,;wU 4WA,--4P�jwiil not cause a discharge for this rain event. Therefore there should c WW be no stormwate��'unoff from the mine pit. Any pumped discharge will be directed to a stilling basin and then to a vegetated swale with a. length in excess of 1000 feet. The suction intake for any water pumped from the mine site is at the far end of the mine relative to the excavation and observations indicate high clarity of the water at the suction point. (b) BMP Controls Inspection and Maintenance. All stormwater controls shall be inspected. All inspections are to be documented with a written record of repairs. BMPs shall be inspected by or under the direction of the permittee at least once every seven calendar days and within 24 hours after any storm event that results in a discharge, unless the site is inactive. The permittee has been informed of the requirement to inspect, and if required, repair all stormwater controls at least once every seven calendar days and within 24 hours after any storm event that results in a discharge. However, discharge is unlikely as stated above due to the fact that the mine pit provides over 3 feet of storage in excess of the 100 year rain event. Reduced inspections for inactive mines: For inactive mines that have obtained an "Inactive Renewal" Mining Permit from DLR, BMPs must be inspected at least once every month, and within 24 hours of any storm event of 0.5 inches or more. For mines where active mining has suspended temporarily, but the mine maintains an active Mining Permit from DLR, the permittee must certify to DWQ that all portions of the site where clearing, grading, andlor excavation activities have temporarily ceased have been stabilized with vegetation, and may then conduct BMP inspections within 24 hours of any storm event that results in a discharge (no weekly minimum). The permittee must send certification to the DWQ Regional Office of "inactive" status and may be subject to an inspection for verification. The permittee must also notify the Regional Office upon resuming mining activities. The permittee has been informed of the requirements for a mine in an "inactive" status. A rain gauge and monitoring records are to be kept on site. BMPs shall be operated and maintained. BMPs must be cleaned out when sediment storage capacity is at 50% permitted volume. If visible sedimentation is leaving the property, corrective Permit No. NCG020000 Part 111 Page 3 of 16 Pages action shall be taken to reduce the discharge of sediments. Visible sedimentation shall be recorded with a brief explanation of measures taken to prevent future releases, as well as any measures taken to remove the sediment that has left the site. Visible sedimentation records shall be kept onsite. All other stormwater specific controls (e.g. oilAvater separators) shall be inspected and qualitatively monitored (as per Part i/I. D) on a semi-annual schedule. A log of all sampling data, including activities taken to implement BMPs associated with vehicle maintenance activities, shall be maintained and incorporated into the SPPP and kept onsite and available for inspection purposes. These items shall be available for the duration of the permit term and made available to the Director upon request. These data shall be sent to the Regional Office upon request. The permittee has been informed of the requirement to maintain a rain gauge and monitoring records on site as well as the requirement to take corrective action per General Permit No. NCG020000 Part ill. (c) Secondary Containment Requirements and Records. Secondary containment is required fora bulk storage of liquid materials; storage in any amount of Section 313 of Title 111 of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals; and storage in any amount of hazardous substances, in order to prevent leaks and spills from contaminating stormwater runoff. A table or summary of all such tanks and stored materials and their associated secondary containment areas shall be maintained. If the secondary containment devices are connected to stormwater conveyance systems, the connection shall be controlled by manually activated valves or other similar devices (which shall be secured closed with a locking mechanism), and any stormwater that accumulates in the containment area shall be at a minimum visually observed for color, foam, outfall staining, visible sheens and dry weather flow, prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found to be uncontaminated by any material. Records documenting the individual making the observation, the description of the accumulated stormwater, and the date and time of the release shall be kept for a period of five (5) years. There are no secondary containment areas located on this site. 4. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall incorporate an assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel (or the team) responsible for implementing the SPRP shall be identified in a written list incorporated into the SPRP and signed and dated by each individual acknowledging their responsibilities for the plan. A responsible person shall be on -site at all times during facility operations that have the potential to contaminate stormwater runoff through spills or exposure of materials associated with the facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP, but may not be sufficient to completely address the stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be incorporated by reference into the SPRP. The site will be used loading mined fill sandldirt only. There will be no transfer of fluids or other pollutants that would necessitate the incorporation of a SPRP. 5. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and good housekeeping program shall be developed and implemented. The program shall ensure equipment used during mining activity on a site must be operated and maintained to prevent potential pollution of the surface water or groundwaters of the state. Fuels, lubricants, coolants, hydraulic fluids, or any other petroleum products shall not be discharged on the ground or into surface waters_ Spent lubricants and fuels shall be disposed of properly and in accordance with applicable federal disposal regulations_ Spilled fluids shall be cleaned up to the maximum extent practicable and properly disposed of to prevent entry to surface waters or groundwaters of the state. The program shall establish schedules of inspections, maintenance, and housekeeping measures for vehicle maintenance and industrial activity areas (including material storage and handling areas, Permit No. NCG020000 Part 111 Page 4 of 16 Pages disposal areas, process areas, loading and unloading areas, and haul roads), where not already addressed under another element of this Plan. Schedules for inspections, maintenance, and housekeeping, and documentation that these program elements are being implemented, shall be recorded and maintained in the SPPP. The permittee has been informed of the requirement to maintain all mining equipment in good working order to prevent any discharge of pollutants into surface waters or groundwater. Any fluids spilled on site shall be cleaned up and the area remediated to maximum extent practicable. 6. Employee Training. Training programs shall be developed and training provided at a minimum on an annual basis for facility personnel with responsibilities for: spill response and cleanup, preventative maintenance activities, and for any of the facility's operations that have the potential to contaminate stormwater runoff. Facility personnel (or team) responsible for implementing the training shall be identified, and their annual training shall be documented by the signature of each employee trained. Additional required training items include: used oil management, spent solvent management, disposal of spent abrasives, disposal of vessel wastewaters, fueling procedures, sanding, painting and blasting procedures, and used battery management. The permittee has been informed of the requirement to identify and train all personnel involved in any of the mine operations that have the potential to contaminate stormwater runoff. And at a minimum this training is to take place on an annual basis. Certification Statement in Accordance with NCDENR-DWQ General Permit No. NCG02000 Part IV, Section B, Paragraph 55 I certify under penalty of law, that any stormwater outfalls for- the John D. Ward Mine have been evaluated for the presence of non- stormwater discharges. This evaluation was prepared under my direction in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based upon my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true. accurate and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fines and imprisonment for knowing violations.

The Owner of the property; Dr. John D. Ward, plans to excavate material from said property and offer the sand material that is suitable for construction purposes for sale to the general public as well as to use some of the sand material in the future development of additional property he owns within the local area. Determination of the rate of withdrawal: Initial pumping and recharge —In order to determine the rate of withdrawal and groundwater recharge for the site, we initiated a 24 hour drawdown test whereby a contractor utilized pumps to remove water from a previously excavated area of the property that continuously maintained a static water level. The reader is requested to see the existing conditions map within the design plan set. Readings on the changes in water elevations were recorded throughout the 24 hour test. An initial report provided to the Owner is attached. To summarize the initial report, it was impossible to determine the withdrawat and recharge rate from the first testing. Although precise measurements had been recorded, the initial results showed that the static water level was both rising and then lowering although no further pumping had occurred. We concluded that the existing excavated area needed to be pumped completely down in order to be able to better estimate the withdrawal and groundwater recharge rate. Final pump dawn and recharge determination - The owner solicited bids from several local contractors to provide the pumping capacity necessary to pump the existing excavated area completely down. A contractor was selected and larger pumps were then used that allowed for a successful test. Survey data and measurements were made immediately prior to beginning and immediately alter completion of the drawdown test. The entire existing excavated area was pumped down on Monday, November 19, 2009. Our survey crew was at the site to record the bottom of the existing excavated area on the morning of "Tuesday, November 20th. It was noted that a small swale exists in the bottom of the excavated area that directs all water to one end (where a pump intake is possible). The intake elevation is approximately two feet below the actual basin floor. The surface area of the swale is very small and negligible in the water removal volume calculations. There are a few areas of the bottom of the excavated area that extend up anywhere from six inches to about a foot. However, most of the bottom is at the same elevation, as can be seen in the last of the three enclosed photographs. On Wednesday, November 21 st, our survey crew informed us that the water level had not risen to a predetermined benchmark elevation. Again, the following day our survey crew verified that the water had not vet risen to the predetermined benchmark elevation. We went to the site to observe. Walking around the entire drained excavated area, we saw where there were three areas in which groundwater was entering but that the rate was very slow. Still there had not accumulated enou&h water in the small swale area to cover the bottom and establish a good elevation to start calculating the recharge rate. On Friday, November 23rd we again returned to the site for observation. There had been some rain overnight - just enough to wet the area - but negligible in amount. In observing the excavated area, the water level still had not risen above the bottom of the basin as can be seen on the last three pictures that are attached. Therefore, after a total of seventy-two hours, the water level still had not risen more than approximately six inches above the basin bottom -- not enough to even fill the small pumping intake swale. Summary: In reviewing the on -site data taken from August 22 to August 29 after the elevation of the pond had been lowered, showed that the surface elevation had actually dropped 0.13 feet or an average of' 0.0186 feet per day. Over this same period, there was 0.058 feet of rainfall that is not included in the data above. Ten thousand gallons is approximately 1,336 cubic feet. This amount spread out over the surface area of the lake (73,479 square feet) would give a rise in elevation of approximately 0.0182 feet. Therefore we concluded that evaporation at the site is will be the controlling factor. In discussing this with both Rob Moul and John Williams of the Land Management Group, they also concluded this to be the case. As a result of interviewing the contractor that performed the existing excavation on the property, we learned they had been operating the small pumps that were used in our initial pumping test approximately once a week in order to remove any accumulated water. We also learned that in order to maintain a dry excavation area they would not have to use all of the four small pumps that were present but only one or two at a time. They only used all four small pumps in order to maintain a dry excavation area immediately after a significant rainfall event. Therefore, we concluded based upon the data collected during the final November 19 through 23`d test period that the withdrawal and recharge rate for this small area would be more rainfall driven than recharge driven and since the small swale still had not been filled that the total withdrawal rate would be less than 10,000 gallons per day. ,�-' L%* Donald R Butler, PE East Coast Engineering & Surveying, PC East Coast Engineering & Surveying, P.

Ward Mine Brunswick County, North Carolina Dear Ms. Rogers: Please find enclosed two (2) copies each of the following in response to your December 2, 2009 letter regarding the subject project: I) The signed return receipt from certified snail that the Chief Administrative Officer of the County (County Manager) has been properly notified. 2) The Notice of Intent (NOI) that we are sending today to the NC Division of Water Quality (DWQ) to request coverage under the current National Pollutant Discharge Elimination System (NPDES) General Permit NCG02000 for stormwater discharges associated with sand mining activities. As requested, we contacted Ms. Linda Willis to coordinate our submittal of this request. It is understood that your department will issue the mining permit after the request for coverage under the NPDES General Permit has been approved by the DWQ. 3) The Mining Plan (Sheet I of 3) that has been revised to indicate the discharge point of the stilling basin and the method of discharge (i.e. by pumping only)- 4) The Mining Plan (Sheet I of 3) that has been revised to provide a_construction detail of the stilling basin. 5) The Evaluation of Requirements for Operation and Monitoring Plan and Stormwater Pollution and Prevention Plan report that we are submitting today to Ms. Linda Willis ofthe DWQ as part of our Client's request for coverage under the aforementioned NPDES General Pennit. 6) The hydraulic calculations and supporting documents (included as Appendix D within the report mentioned within item 45 above) which includes the estimated withdrawal rate (in gallons per day) at which the excavation will be periodically dewatered. This report provides more detail regarding the proposed pumping, rate of less than 10,000 gpd and how we -estimated the withdrawal rate. 7) The Mining Plan (Sheet I of')) and page 10 of the application that have both been revised to provide more detailed information on the proposed screening on the northeast boundary of the site. Please be aware that there is existing evergreen vegetation on both sides of the existing ditch in this area as well as evergreen vegetation along both side slopes of this ditch since it has existed for many years. As requested, we have specified that additional screening between the top of the ditch and the proposed silt fence by using 15 gallon wax myrtles (l .5" its diameter at planting) on 10-foot spacing. This has been recommended to us by a local landscaper in an effort to increase the current opacity from about 50 to 60 percent to 90 to 100 percent opacity within two year, of planting.

The Mine Acreage Data Table on the Mining Plan has been moved to the top center of Sheet I of 3. Stockpiles will disturb 0.35 ac., Wastepiles will disturb 0.16 ac.. Haul Roads outside of the tract boundary will disturb 0.50 ac., Haul Roads within the tract boundary will disturb 0.35 ac., the Mine Excavation will disturb 5.21 ac., and the Other Disturbed Area category will disturb 1.36 ac. The Other Disturbed Area category includes areas that will be disturbed between and around the designated stockpiles and wastepiles and other areas within the tract boundary that will be need to be disturbed as part of the operation such as the stilling basin and the area between the on -site haul road and the mine excavation. Basically, the Other Disturbed Area category includes all non listed land disturbing activities that will be located inside of the silt fence and Limits of Disturbance. The total disturbed area has been slightly increased as a result of the requested expansion of the permit boundary all the way to the edge of pavement of NC Highway 130. The total disturbed area for the project is 7.93 acres while the Total Permit Boundary area is 11.50 acres. These changes have caused an increase on the determination of the bond. The bond amount we calculate has increased from $6,100.00 to $6,900.00 as a result of these changes. 9) The Mining Plan (Sheet I of 3) that has been revised to specify that all buffers are to be undisturbed not `undisturbed and unexcavated". All existing vegetation within the required buffers will be retained. Also enclosed is a copy of our submittal letter dated today to Ms. Willis in regards to the request for coverage under the current NPDES General Permit NCG020000. Also enclosed is a copy of the associated NOI application form being provided. Lastly, as mentioned within item #5 above, enclosed are two (2) copies of our Evaluation of Requirements for Operations and Monitoring Plan and Stormwater Pollution Prevention Plan report that we are also submitting to Ms. Willis. On behalf of our Client, we appreciate your assistance in regards to this particular project. Hopefully the submittal of the enclosed information will now allow the issuance of the mining permit.
