The NOV was issued after an inspection on February 22, 2011 revealed that the sites did not have a Stormwater Pollution Prevention Plan, and had not submitted annual monitoring reports. Garner Construction Company immediately contacted me and asked me to assist them in bringing the sites into compliance with their permits. Neither site had discharged any stormwater or mine dewatering wastewater during 2010, and Annual Discharge Monitoring Reports were sent to your office with this information on February 25, 2011, as acknowledged in your letter. Garner Construction Company will continue to monitor any pit discharges on a quarterly basis as required in the permit. Stormwater Pollution Prevention Plans were prepared for each site before March 1, and were placed on file in the Garner Construction Company office in Newport, NC. We were not aware that these Plans were required to be submitted to the regional office. It was our understanding of the permit requirements that the Plans were to be kept on file in the facility office and available for inspection upon request. Please find enclosed with this letter a copy of the main text of the plans, along with some of the appendix information included in the original binders. Note that the Plans on file in the main office are quite bulky, and are kept in a 3-ring binder. It is hoped that the information included herein will sufficient for your review.

Goldstein and Associates (RJG&A) has completed a revised Operation and Monitoring Plan for the Nine Foot Road Mine #2 site (attached) for Garner Construction Company in Newport, NC. Information presented here and in the Plan is based on our detailed on -site evaluation and formal delineation of wetlands and their associated hydrology on the 48.23 acre property (Carteret County tax PIN 633809166091000). The property is bordered to the north by Nine Foot Road (NC 1124) and to the south by the Newport River. The northeastern corner of the parcel that borders Nine Foot Road is 1.17 miles west of US 70. The property's southwestern corner is approximately 1,000 feet east of the confluence of Big Ramhom Branch and the Newport River (Figure 1). Discharge from mine dewatering will ultimately flow into the Newport River whose DWQ Surface Use classification is "C". During our site evaluation, consecutively numbered survey ribbons were hung along all wetland boundaries on the property, pursuant to the US Army Corps of Engineers 1987 Wetland Delineation Manual. The location of all wetland boundary flags and ditch channel centerlines and/or banks were recorded using sub -meter accurate GPS. Wetland flags visible from all disturbance areas will be maintained throughout the life of the mine. The USACE site visit determined that no portion of the mining area was in the Corps' jurisdiction as stated in their September 22, 2006 letter to the client (Appendix A). For over a year, water table depth data has been collected at this site and at an appropriate hydrologic reference area on a tributary west of the site, whose confluence is just upstream along the Newport River. Four groundwater wells are installed at the reference site and eight groundwater wells are associated with two wetlands on the mine site (Figure 1) (Appendix B).

Goldstein and Associates, Inc. ENVIRONMENTAL CONSULTANTS Existing Conditions Wetlands Two wetlands exist within the Nine Food Road Mine #2 parcel. Wetland A is the northern -most wetland and occupies a low 2.13 acre area between the proposed mine excavation site (to the south) and the northern property line (Figure 2). The Soil Survey of Carteret County North Carolina (Goodwin, 1987) indicates that most of the area inside the wetland boundary is mapped as Rains fine sandy loam, while the southern -most portion is mapped as Autryville loamy fine sand. The wetland is bordered to the west by a narrow, mature loblolly pine stand (Pinus taeda), which parallels a south -flowing ditch. A narrow loblolly stand also separates the southern boundary of Wetland A from the mining area while the eastern boundary is bordered by a mixed pinelhardwood stand. A portion of the wetland's northern boundary is adjacent to a small ditch that receives south -flowing stormwater from residential lots between the mine parcel and Nine Foot Road. On -site indicators (i.e. water stained leaves, rack and drift lines and topography) indicate that Wetland A receives surface flow during storm events from a drainage ditch connected to the wetland's eastern tip. This ditch receives flow from the north through an off -site stormwater ditch and runoff from residential parcels. Wetland B occupies the southern third of the parcel (15.74 acres) (Figure 2). It is south of the proposed excavation area and entirely inside the existing cypress/hardwood floodplain forest that is directly connected to and contiguous with the Newport River. Hydrology The surface hydrology at this property involves three major ditches and the secondary ditches that flow into each. The primary source of surface waters through the site is the south flowing ditch that enters at the property's northwest corner (Ditch 1) (Figure 2). At its point of entry into the mine parcel, Ditch 1 (DI) is transporting flows from Nine Foot Road and the subdivisions to the west and northwest along a network of inter- connected roadside ditches (approximately 95 off -site acres). DI flows east across the northern portion of the property and then turns south, crosses an adjacent parcel, and receives flow from a west flowing ditch near the parcel's northern boundary. D1 receives flow from two more small west flowing ditches as it continues south across the non - forested portion of the parcel. D 1 enters the floodplain forest and flows southeast for 125 feet, where it splits. One branch turns south and gradually shallows before equaling swamp swale elevation and disappearing (<100 feet). The eastern branch turns east and parallel's the toe of slope to the north until it joins with Ditch 2 (D2). D2 is contained entirely inside the floodplain forest. It flows west just inside the treeline at Wetland B's northern boundary and then turns south for 830 feet until it discharges into one of the Newport River's many oxbows (Figure 2). Page 2 Robert J. Goldstein and Associates, Inc. ENVIRONMENTAL CONSULTANTS D3 flows south along the parcel's eastern -most boundary until just inside the floodplain treeline, where the ditch splits, one portion turns east and crosses a small pine stand into the floodplain forest of the adjacent parcel. The western portion of D3 continues south and drains into a swamp swale at Wetland B's northern boundary. Mining operations have been conducted at this site within the constraints of the existing permit. These activities have resulted in two shallow pits that will be utilized for dewatering wastewater storage and groundwater recharge.

Goldstein Bic Associates, Inc. ENVIRONMENTAL CONSULTANTS 1221 Corporation Parkway, Raleigh, NC 27610 (919) 872-1174 www.dgaCarolina.com Pursuant to North Carolina Division of Land Resources (DLR) pen -nit 16-61 (originally issued on 17 November 2005, expires on 17 November 2015), Garner Construction Company plans to mine sand from its Nine Foot Road Mine #2 in Carteret County. The type of discharge is mine dewatering. Operation Tv -Des of excavation Mine dewatering will occur as needed during two different stages in the excavation process: 1) mechanical excavation using track hoes, front -end -loaders and haul trucks and 2) hydraulic excavation using a hydraulic dredge controlled from a barge. Dewatering will first become necessary when mechanical pit excavation extends below the water table. This type of excavation will continue until the pit depth is approximately 10 feet below the water table. At this point, dewatering will cease and the pit will be allowed to fill up to water table depth with groundwater, which will provide the water depth necessary to float the dredge barge. When the barge is in place, mining will begin using the hydraulic dredge. Dewatering will begin again after all areas in the pit have been mined to the extent of the dredge hose (approximately 25 feet below the water surface). Dewatering is necessary at this stage to lower the dredge barge and allow access to mine deeper materials. The maximum depth of the permitted mine is 40 feet below the existing surface elevation, which ranges from five to ten feet above mean sea level within the mining area. Sequence of excavation The mine will be split into two separate pits, Pit 1 and Pit 2 (Figure 2), that will be excavated sequentially, not simultaneously. Some mechanical excavation of both Pits has already occurred within the constraints of the original mining permit but dewatering will be required to continue mechanical excavation. Within the Pit 1 area, a temporary settling basin will receive water from the dewatering pump after the opposite pit area is already filled. During mechanical excavation of Pit 1, dewatering will discharge into Pit 2 until filled and then into the temporary settling basin and then into Ditch 1. During mechanical excavation of Pit 2, dewatering will discharge into Pit 1 until filled and then into the temporary settling basin. The sediment basin will receive no additional flow from stormwater runoff, Water will discharge by sheet flow across a gravel spillway into Ditch 1. Once hydraulic excavation begins, dewatering of Pit 1 will discharge into Pit 2 until filled and then into the temporary settling basin. When all other areas of Pit 1 have been excavated to the appropriate depth, the temporary settling basin will also be excavated, leaving the gravel spillway portion of this structure intact. In this way, Pit 1 becomes the settling basin itself. During mechanical excavation of Pit 2, dewatering will discharge into Pit 1. When filled, water will discharge from Pit 1 through the remaining sediment basin spillway area into Ditch 1. When all areas of both Pits are excavated, dewatering will cease permanently. The remaining portion of sediment basin and the ditch area itself will be excavated to the depth accessible without dewatering. Since the mining plan ensures that one pit will be filling with water during any dewatering activities and since the soils throughout the mining area are coarse sand, water should readily recharge groundwater from the pit area and ultimately recharge the nearby wetlands. Monitoring Wetlands will be monitored using hydrologic data from wells and through qualitative visual assessment of the overall condition of the soils and vegetation in the wetlands. These data will be used to determine if impacts to the wetlands are occurring due to the mining operation. Thresholds of these data have been chosen and if exceeded, will result in remedial action on the part of the mining operator. Hydrologic Water table depths inside the permit area vary from water at the surface to more than ten feet below the surface depending on the time of year and weather and climate conditions. Eight groundwater monitoring wells were installed on the mine site on 16-18 May 2007, pursuant to Vepraskas, 2005 (Installing Equipment for the Hydric Soil Technical Standard). Three wells (9ft-1, 9ft-2, and 9ft-3) were installed inside wetland A. One well (9ft-4) was installed just outside wetland A in a forested upland. Four monitoring wells were installed in wetland B (9ft-5, 9ft-6, 9ft-7, and 9ft-8) (Figure 2). Four wells were also installed on an adjacent "reference" property (K-1, K-2, K-3, and K-4) (Carteret County PIN 63280234) (Figure 2). Depth to water table (below soil surface) has been recorded at all sites from 19 May 2007 to 06 May 2008. Mean monthly depth to water table at all wells ranges from 0 to 3.51 feet with well depths at approximately 4.5 feet (Figure 3). The average monthly depth to water table for the reference site is 1.55 feet, for wetland A is 1.06 feet, and for wetland B is 1.57 feet. Since depth to water table at the mine site wetlands is the same or smaller than that depth at the reference site, the two sites can be compared monthly to determine the impact of mining operations on the on -site wetlands. Well data has been including in Appendix B. Monthly readings for each well are shown graphically along with the monthly precipitation data from NC State Climate Office gauges at Cherry Point MCAS and the Beaufort Airport. Raw well data are presented in a table. Once dewatering activities have begun, depth to water table will be measured and recorded monthly at all sites. If the monthly average depth to water table in Wetland A (average of 9ft-1, 9ft-2, and 9ft-3) or Wetland B (average of 9ft-5, 9ft-6, 9ft-7, and 9ft-8) is ever one foot greater than the monthly average depth to water table at the reference site (average of K-1 through K-4), all dewatering on the mine site will be suspended until reference and monitoring groundwater levels equilibrate. Similarly, if the monthly average depth to water table at on -site wetlands becomes less than one foot than monthly average depth to water table at the reference wells, dewatering will cease, until on -site groundwater levels equilibrate with reference levels. Visual Assessment During collection of well data, a qualitative visual assessment will be performed of the vegetative and physical characteristics of each wetland. Any changes to plant species composition or signs of soil instability will be recorded. Dewatering inside the permit boundary will be suspended if significant changes to vegetation or soil parameters observed inside wetlands A or B, not also occurring in the reference area, appear to be the result of pit dewatering (e.g. high mortality of obligate wetland species, or significant invasion of exotic facultative wetland species). All monitoring data collected will be maintained by and available through the site operator. a S w�.V+ �, _ M �r •.- .41Io. 10 IL C J i' . if2. ip .f�� r 7"•.���� e t ti n , ;':,' .., sZ `f.

Goldstein and Associates (RJG&A) has completed a revised Operation and Monitoring Plan for the Nine Foot Road Mine 92 site (attached) for Garner Construction Company in Newport, NC. Information presented here and in the Plan is based on our detailed on -site evaluation and formal delineation of wetlands and their associated hydrology on the 48.23 acre property (Carteret County tax PIN 633809166091000). The property is bordered to the north by Nine Foot Road (NC 1124) and to the south by the Newport River. The northeastern corner of the parcel that borders Nine Foot Road is 1.17 miles west of US 70. The property's southwestern corner is approximately 1,000 feet east of the confluence of Big Ramhorn Branch and the Newport River (Figure 1). Discharge from mine dewatering will ultimately flow into the Newport River whose DWQ Surface Use classification is "C". During our site evaluation, consecutively numbered survey ribbons were hung along all r wetland boundaries on the property, pursuant to the US Army Corps of Engineers 1987 soy �''� ,a Wetland Delineation Manual. The location of all wetland boundary flags and ditch nW 0Sed2 channel centerlines and/or banks were recorded using sub -meter accurate GPS. Wetland flags visible from all disturbance areas will be maintained throughout the life of the mine. The USACE site visit determined that no portion of the mining area was in the Corps' jurisdiction as stated in their September 22, 2006 letter to the client (Appendix A). For over a year, water table depth data has been collected at this site and at an appropriate hydrologic reference area on a tributary west of the site, whose confluence is just upstream along the Newport River. Four groundwater wells are installed at the reference q+4— site and eight groundwater wells are associated with two wetlands on the mine site l (Figure 1) (Appendix B).

Wetland A is the northern -most wetland and occupies a low 2.13 acre area between the proposed mine excavation site (to the south) and the northern property line (Figure 2). The Soil Survey of Carteret County North Carolina (Goodwin, 1987) indicates that most of the area inside the wetland boundary is mapped as Rains fine sandy loam, while the southem-most portion is mapped as Autryville loamy fine sand. The wetland is bordered to the west by a narrow, mature loblolly pine stand (Prnus taeda), which parallels a south -flowing ditch. A narrow loblolly stand also separates the southern boundary of Wetland A from the mining area while the eastern boundary is bordered by a mixed pine/hardwood stand. A portion of the wetland's northern boundary is adjacent to a small ditch that receives south -flowing stormwater from residential lots between the mine parcel and Nine Foot Road. On -site indicators (i.e. water stained leaves, rack and drift lines and topography) indicate that Wetland A receives surface flow during storm events from a drainage ditch connected to the wetland's eastern tip. This ditch receives flow from the north through an off -site stormwater ditch and runoff from residential parcels. Wetland B occupies the southern third of the parcel (15.74 acres) (Figure 2). It is south of the proposed excavation area and entirely inside the existing cypress/hardwood floodplain forest that is directly connected to and contiguous with the Newport River. Hydrology The surface hydrology at this property involves three major ditches and the secondary ditches that flow into each. The primary source of surface waters through the site is the south flowing ditch that enters at the property's northwest comer (Ditch 1) (Figure 2). At its point of entry into the mine parcel, Ditch I (D1) is transporting flows from Nine Foot Road and the subdivisions to the west and northwest along a network of inter- connected roadside ditches (approximately 95 off -site acres). D 1 flows east across the northern portion of the property and then turns south, crosses an adjacent parcel, and receives flow from a west flowing ditch near the parcel's northern boundary. D1 receives flow from two more small west flowing ditches as it continues south across the non - forested portion of the parcel. DI enters the floodplain forest and flows southeast for 125 feet, where it splits. One branch turns south and gradually shallows before equaling swamp swale elevation and disappearing (<100 feet). The eastern branch turns east and parallel's the toe of slope to the north until it joins with Ditch 2 (D2). D2 is contained entirely inside the floodplain forest. It flows west just inside the treeline at Wetland B's northern boundary and then turns south for 830 feet until it discharges into one of the Newport River's many oxbows (Figure 2). Page 2 Robert J. Goldstein and Associates, Inc. ENVIRONMENTAL, CONSULTANTS D3 flows south along the parcel's eastern -most boundary until just inside the floodplain treeline, where the ditch splits, one portion turns east and crosses a small pine stand into the floodplain forest of the adjacent parcel. The western portion of D3 continues south and drains into a swamp swale at Wetland B's northern boundary. Mining operations have been conducted at this site within the constraints of the existing permit. These activities have resulted in two shallow pits that will be utilized for dewatering wastewater storage and groundwater recharge.

The type of discharge is mine dewatering. Operation Types of excavation Mine dewatering will occur as needed during two different stages in the excavation process: 1) mechanical excavation using track hoes, front -end -loaders and haul trucks and 2) hydraulic l excavation using a hydraulic dredge controlled from a barge. Dewatering will first become necessary when mechanical pit excavation extends below the water table. This type of 1 / excavation will continue until the pit depth is approximately 10 feet below the water table. At O / this point, dewatering will cease and the pit will be allowed to fill up to water table depth with groundwater, which will provide the water depth necessary to float the dredge barge. When the Tel barge is in place, mining will begin using the hydraulic dredge. Dewatering will begin againi� I after all areas in the pit have been mined to the extent of the dredge hose (approximately 25 feet below the water surface). Dewatering is necessary at this stage to lower the dredge barge and allow access to mine deeper materials.

Monitoring Wetlands will be monitored using hydrologic data from wells and through qualitative visual assessment of the overall condition of the soils and vegetation in the wetlands. These data will be used to determine if impacts to the wetlands are occurring due to the mining operation. Thresholds of these data have been chosen and if exceeded, will result in remedial action on the part of the mining operator. Hydrologic Data Water table depths inside the permit area vary from water at the surface to more than ten feet below the surface depending on the time of year and weather and climate conditions. Eight groundwater monitoring wells were installed on the mine site on 16-18 May 20 , pursuant to Vepraskas, 2005 (Installing Equipment for the Hydric Soil Technical Standard. Three wells (9ft-1, 9ft-2, and 9ft-3) were installed inside wetland A. One well (911-4) was installed just outst a wet an Tn a forested upland. Four monitoring wells were installed in wetland B (9ft-5, 911-6, 9ft-7, and 9ft-8) (Figure 2). Four wells were also installed on an adjacent "reference" property (K-1, K-2, K-3, and K-4) (Carteret County PIN 63280234) (Figure 2). Depth to water table (below soil surface) has been recorded at all sites from 19 May 2007 to 06 May 2008. Mean monthly depth to water table at all wells ranges from 0 to 3.51 feet with well depths at approximately 4.5 feet (Figure 3). The average monthly depth to water table for the reference site is 1.55 feet, for wetland A is 1.06 feet, and for wetland B is 1.57 feet. Since depth to water table at the mine site wetlands is the same or smaller than that depth at the reference site, the two sites can be compared monthly to determine the impact of mining operations on the on -site wetlands. Well data has been including in Appendix B. Monthly readings for each well are shown graphically along with the monthly precipitation data from NC State Climate Office gauges at Cherry Point MCAS and the Beaufort Airport.

Goldstein and Associates (RJG&A) has completed a revised Operation and Monitoring Plan for the Nine Foot Road Mine 92 site (attached) for Garner Construction Company in Newport, NC. Information presented here and in the Plan is based on our detailed on -site evaluation and formal delineation of wetlands and their associated hydrology on the 48.23 acre property (Carteret County tax PIN 633809166091000). The property is bordered to the north by Nine Foot Road (NC l 124) and to the south by the Newport River. The northeastern corner of the parcel that borders Nine Foot Road is 1.17 miles west of US 70. The property's southwestern corner is approximately 1,000 feet east of the confluence of Big Ramhorn Branch and the Newport River (Figure 1). Discharge from mine dewatering will ultimately flow into the Newport River whose DWQ Surface Use classification is "C". During our site evaluation, consecutively numbered survey ribbons were hung along all wetland boundaries on the property, pursuant to the US Army Corps of Engineers 1987 Wetland Delineation Manual. The location of all wetland boundary flags and ditch channel centerlines and/or banks were recorded using sub -meter accurate GPS. Wetland flags visible from all disturbance areas will be maintained throughout the life of the mine. The USACE site visit determined that no portion of the mining area was in the Corps' jurisdiction as stated in their September 22, 2006 letter to the client (Appendix A). For over a year, water table depth data has been collected at this site and at an appropriate hydrologic reference area on a tributary west of the site, whose confluence is just upstream along the Newport River. Four groundwater wells are installed at the reference site and eight groundwater wells are associated with two wetlands on the mine site (Figure 1) (Appendix B).

ENVIRONMENTAL CONSULTANTS Existing Conditions Wetlands Two wetlands exist within the Nine Food Road Mine #2 parcel. Wetland A is the northern -most wetland and occupies a low 2.13 acre area between the proposed mine excavation site (to the south) and the northern property line (Figure 2). The Soil Survey of Carteret County North Carolina (Goodwin, 1987) indicates that most of the area inside the wetland boundary is mapped as Rains fine sandy loam, while the southern -most portion is mapped as Autryville loamy fine sand. The wetland is bordered to the west by a narrow, mature loblolly pine stand (Pinus taeda), which parallels a south -flowing ditch. A narrow loblolly stand also separates the southern boundary of Wetland A from the mining area while the eastern boundary is bordered by a mixed pine/hardwood stand. A portion of the wetland's northern boundary is adjacent to a small ditch that receives south -flowing stormwater from residential lots between the mine parcel and Nine Foot Road. On -site indicators (i.e. water stained leaves, rack and drift lines and topography) indicate that Wetland A receives surface flow during storm events from a drainage ditch connected to the wetland's eastern tip. This ditch receives flow from the north through an off -site stormwater ditch and runoff from residential parcels. Wetland B occupies the southern third of the parcel (15.74 acres) (Figure 2). It is south of the proposed excavation area and entirely inside the existing cypress/hardwood floodplain forest that is directly connected to and contiguous with the Newport River, Hydrology The surface hydrology at this property involves three major ditches and the secondary ditches that flow into each. The primary source of surface waters through the site is the south flowing ditch that enters at the property's northwest corner (Ditch 1) (Figure 2). At its point of entry into the mine parcel, Ditch 1 (D 1) is transporting flows from Nine Foot Road and the subdivisions to the west and northwest along a network of inter- connected roadside ditches (approximately 95 off -site acres). D I flows east across the northern portion of the property and then turns south, crosses an adjacent parcel, and receives flow from a west flowing ditch near the parcel's northern boundary. D I receives flow from two more small west flowing ditches as it continues south across the non - forested portion of the parcel. D 1 enters the floodplain forest and flows southeast for 125 feet, where it splits. One branch turns south and gradually shallows before equaling swamp swale elevation and disappearing (<100 feet). The eastern branch turns cast and parallel's the toe of slope to the north until it joins with Ditch 2 (132). D2 is contained entirely inside the floodplain forest. It flows west just inside the treeline at Wetland B's northern boundary and then turns south for 830 feet until it discharges into one of the Newport River's many oxbows (Figure 2). Page 2 Robert J. Goldstein and Associates, Inc. ENVIRONMENTAL. CONSULTANTS D3 flows south along the parcel's eastern -most boundary until just inside the floodplain treeline, where the ditch splits, one portion turns east and crosses a small pine stand into the floodplain forest of the adjacent parcel. The western portion of D3 continues south and drains into a swamp swale at Wetland B's northern boundary. Mining operations have been conducted at this site within the constraints of the existing permit. These activities have resulted in two shallow pits that will be utilized for dewatering wastewater storage and groundwater recharge. Please review the attached Operation and Monitoring Plan for the site. Should you have questions, or desire clarification on any point, plcase call or e-mail.

The type of discharge is mine dewatering.

Dewatering will begin again after all areas in the pit have been mined to the extent of the dredge hose (approximately 25 feet below the water surface). Dewatering is necessary at this stage to lower the dredge barge and allow access to mine deeper materials. The maximum depth of the permitted mine is 40 feet below the existing surface elevation, which ranges from five to ten feet above mean sea level within the mining area. SMuence of excavation The mine will be split into two separate pits, Pit I and Pit 2 (Figure 2), that will be excavated sequentially, not simultaneously. Some mechanical excavation of both Pits has already occurred within the constraints of the original mining permit but dewatering will be required to continue mechanical excavation. Within the Pit 1 area, a temporary settling basin will receive water from the dewatering pump after the opposite pit area is already filled. During mechanical excavation of Pit 1, dewatering will discharge into Pit 2 until filled and then into the temporary settling basin and then into Ditch 1. During mechanical excavation of Pit 2, dewatering will discharge into Pit 1 until filled and then into the temporary settling basin. The sediment basin will receive no additional flow from stormwater runoff. Water will discharge by sheet flow across a gravel spillway into Ditch 1. Once hydraulic excavation begins, dewatering of Pit i will discharge into Pit 2 until filled and then into the temporary settling basin. When all other areas of Pit 1 have been excavated to the appropriate depth, the temporary settling basin will also be excavated, leaving the gravel spillway portion of this structure intact. In this way, Pit 1 becomes the settling basin itself. During mechanical excavation of Pit 2, dewatering will discharge into Pit 1. When filled, water will discharge from Pit 1 through the remaining sediment basin spillway area into Ditch 1. When all areas of both Pits are excavated, dewatering will cease permanently. The remaining portion of sediment basin and the ditch area itself will be excavated to the depth accessible without dewatering. Since the mining plan ensures that one pit will be filling with water during any dewatering activities and since the soils throughout the mining area are coarse sand, water should readily recharge groundwater from the pit area and ultimately recharge the nearby wetlands. Monitoring Wetlands will be monitored using hydrologic data from wells and through qualitative visual assessment of the overall condition of the soils and vegetation in the wetlands. These data will be used to determine if impacts to the wetlands are occurring due to the mining operation. Thresholds of these data have been chosen and if exceeded, will result in remedial action on the part of the mining operator. Hydrologic Data Water table depths inside the permit area vary from water at the surface to more than ten feet below the surface depending on the time of year and weather and climate conditions. Eight groundwater monitoring wells were installed on the mine site on 16-18 May 2007, pursuant to Vepraskas, 2005 (Installing Equipment for the Hydric Soil Technical Standard). Three wells (911-1, 9ft-2, and 9ft-3) were installed inside wetland A. One well (9ft-4) was installed just outside wetland A in a forested upland. Four monitoring wells were installed in wetland B (9ft-5, 9ft-6, 911-7, and 9ft-8) (Figure 2). Four wells were also installed on an adjacent "reference" property (K-1, K-2, K-3, and K-4) (Carteret County PIN 63280234) (Figure 2). Depth to water table (below soil surface) has been recorded at all sites from 19 May 2007 to 06 May 2008. Mean monthly depth to water table at all wells ranges from 0 to 3.51 feet with well depths at approximately 4.5 feet (Figure 3). The average monthly depth to water table for the reference site is 1.55 feet, for wetland A is L06 feet, and for wetland B is 1.57 feet. Since depth to water table at the mine site wetlands is the same or smaller than that depth at the reference site, the two sites can be compared monthly to determine the impact of mining operations on the on -site wetlands. Well data has been including in Appendix B. Monthly readings for each well are shown graphically along with the monthly precipitation data from NC State Climate Office gauges at Cherry Point MCAS and the Beaufort Airport. Raw well data are presented in a table. Once dewatering activities have begun, depth to water table will be measured and recorded monthly at all sites. If the monthly average depth to water table in Wetland A (average of 9ft-1, 9ft-2, and 911-3) or Wetland B (average of 9ft-5, 9ft-6, 9ft-7, and 9ft-8) is ever one foot greater than the monthly average depth to water table at the reference site (average of K-I through K-4), all dewatering on the mine site will be suspended until reference and monitoring groundwater levels equilibrate. Similarly, if the monthly average depth to water table at on -site wetlands becomes less than one foot than monthly average depth to water table at the reference wells, dewatering will cease, until on -site groundwater levels equilibrate with reference levels. Visual Assessment During collection of well data, a qualitative visual assessment will be performed of the vegetative and physical characteristics of each wetland. Any changes to plant species composition or signs of soil instability will be recorded. Dewatering inside the permit boundary will be suspended if significant changes to vegetation or soil parameters observed inside wetlands A or B, not also occurring in the reference area, appear to be the result of pit dewatering (e.g. high mortality of obligate wetland species, or significant invasion of exotic facultative wetland species).

Sullins, P.E. Director Division of Water Quality January 20, 2009 Walton Engineering Attn. Mark Walton P.O. Box 564 Burgaw, North Carolina 28425 Dear Mr. Walton, DWQ has reviewed the proposed O & M plan for Garner Sand Pit in Brunswick County. Currently the mining permit is being sought. Once the mining permit is received the permittee should fill out a notice of intent for the NCG020000 General Permit for mining activities. Herein is a list of items that need to be addressed. 1. The calculations predict a 489 foot radius of influence from dewatering operations at the mine site. Please comment on the distance between the mine pit and the closest surface waters. If any are within this cone of influence, please indicate the measures that will be taken to demonstrate the dewatering activities will not cause adverse impacts. 2. The O & M plan indicates there are 4 monitoring wells, the mine map shows 2. Please show the location of each well on the map. The wells should be in the wetlands in order to be effective in demonstrating wetland hydrology. 3. Groundwater table is shown to be 10 feet deep. The depth of the monitoring wells are being proposed at 5 feet. Will the proposed locations for the '`yells adequately depict the hydrology? 4. Monitoring well data should be collected as soon as possible to establish the wetland hydrology before any dewatering from the mine site occurs. 5. A point source discharge using two 24" pipes is being proposed. What is the expected velocity from these pipes under normal conditions and during the 24 hour 25 year storm event? 6. What are the size of the pumps that will be used in the mine pit for dewatering to the settling basin? Please provide calculations demonstrating the settling basin will have adequate detention time to allow particle settling and the ability to meet the NPDES permit limitations for TSS, settleable solids and turbidity. These calculations should be done based on the maximum flow rate to the settling basin. 7. The mine map shows a 0.5 acre settling pond, the legend identifies 0.2 acres. Please clarify. 8. Please ensure that any tributaries (blue line streams) to Haw Creek are identified on the map. The USGS maps show tributaries bordering the entire mine site (except along the mine road). 9. The monitoring well construction was reviewed by the Aquifer Protection Section. APS stated the wells should have locking caps and should be deep enough to ensure the well intercepts the groundwater table throughout each season and during droughts (suggest 15-20'). The wells should be packed with grout from the ground surface to five feet deep. Please direct any questions concerning proper design of monitoring wells to the Wilmington Regional Office Aquifer Protection Section. 10. The O & M narrative stated the mine boundary would be properly marked to prevent heavy equipment operators from disturbing outside the mine site boundary. The 25 and 50 foot undisturbed buffers must also be marked to ensure the operators will not disturb those areas.

Box 564 Burgaw, North Carolina 28425 WA L ToAi EAiuNEERN Mining Operations In Phase I of mining, water that collects in the mine pit will be pumped out into an existing sediment basin on the subject property) Sediment from the water will be collected in the sediment basin_ The water will filter out of the basin (via rock check dam) and flow into nearby Haws Run Creek. As soon as the mine pit reaches approximately one acre in size, the pit will be converted into a settling pond. Additional miming will be separated from the settling pond by leaving an earth berm between the two areas. Water from the remaining mining activity will be pumped into the, settling pond to infiltrate back into the ground. Two 24" corrugated plastic pipes will be provided to handle overflow in case of storms or in case dewatering exceeds the infiltration capacity of the settling pond. The spill way will also lead to the sediment basin used in Phase I of mining. The buffer areas around the settling pond will be maintained so that rainwater and runoff water from the stockpiles will Clow into the mine pit. When mining is completed, the berm dividing the settling pond and the mine pit will be removed so he entire mine area will form a. pond per the reclamation plan in the State Mining Permit Application. Pumping Frequency The mine in Phase I of the mining process will be pumped as needed to keep the area dry for mining. Pump periods will be monitored by hour meters attached to the pumps. For pumps with no hour meters a pump log will be maintained . These records will be used to determine the Total Flow per the monitoring requirements in Table 1. If there is a negative effect found on the hydrology in the area, the pumping frequency will be modified accordingly. Hvdrolo2v Monitorine There will be four monitoring wells installed around the mine area to monitor the effects on the hydrology in the area. There will be one well installed on the down -slope side of the mine pit (on the northwest side of the settling pond). Another well will be installed on the northeast side of the settling pond. Two others will be installed on the east side and southeast side of the mine pit. The wells will be 2' in diameter at a depth of 10' - 12' b.g.s. (below ground surface) using standard well screen. The well riser will be. approximately 3' — 4' a.g.s. (above ground surface) so that the equipment drivers can see the wells and not destroy them. For the first six months the wells will be checked on a biweekly basis. After the first six months the wells will be checked monthly. After one year of mining the wells will be checked quarterly unless the previous results prove it to be necessary to monitor more frequently. Maintenance The settling pond will be checked regularly and sediment will be removed as needed. The pond water level will be maintained at the invert of the outlet pipe or lower and a maximum depth of 15', The sediment basin and outlet pipe will be monitored accordingly and sediment will be removed as needed. The outlet pipe will be maintained to speci ications of the Mine Plan. The outlet pipe will be checked on a regular basis and maintained as needed. Discharge Monitoring Discharge monitoring and reporting will be performed as specified in Table 1. If the effluent limitations are greater than specified in Table 2 the monitoring frequency will be modified to monthly monitoring of the effluents. Monitoring Reports Discharge monitoring results in accordance with the terms of this permit, NCG020000, shall be submitted no later than 30 days from the end of the monitoring period. Duplicate signed copies of all reports required shall be submitted to the NC DENTR Division of Water Quality, Water Quality Section, ATTENTION.- Central Files, 1617 Mail Service Center, Raleigh, North Carolina 27699-1617, Danny Baysden will report orally any noncompliance within 24 hours Danny Baysden becomes aware of the noncompliance.

Carteret County, NC The purpose of this plan is to provide the necessary precautions to prevent any impact on adjacent wetlands from discharges from the dredge pond. The plan provides protection to the wetlands by providing a steady recharge of water as well as regular monitoring to demonstrate compliance. It should be emphasized that this sand mine is a `'yet mining" operation, and wiil use a hydraulic dredge in its operation; and therefore will not pump water from the pond on a continual basis. The dredge consists of a boat with a pump that removes sand from the bottom of the pond to a small processing plant adjacent to the pond. Water drains from the sand pile, and is recycled back into the pond, maintaining the water level within the pond. In order for this dredge to operate, a high level of natural groundwater must remain within the pond at all times. Since a high level of water will remain within the pond, it is highly unlikely that the natural groundwater level adjacent to the pond will be affected at all. Ho,,vever, in the initial development of the pond, it is necessary to discharge some water to maintain a dry working area. After the pond is developed to a sufficient depth for floating the dredge boa€, the area will be alloyed to fill with groundwater for normal operation. As the pond is developed, there may occasionally be times when it is necessary to discharge some water. However, since the mining method will be l}y hydraulic dredUe, it will always be necessary to maintain a high level of natural groundwater xvithin the pond. This is the most environmentally friendly mining method possible, since it is virtually impossible to discharge any sediment, it maintains natural groundwater levels, and it greatly limits dust since it is a "wct" operation. OPERATION This Wet \-lining operation utilizes a floating hydraulic dredge boat to pump sand from the pond to a small processing area adjacent to the pond. Water from the sand will naturally drain back into the pond, maintaining the water level. The initial pond development requires some stormwater and groundwater to be pumped out of the pond area to maintain a dry working area. As soon as the pond is developed to a depth sufficient for floating the dredge boat, it will be allowed to fill .with water and th_e dredging operation will begin. As the pond is developed with the dredge, it will occasionally be rnecessary to discharge some water from the pond. However, the xyater level .will always remain deep enough to allow the dredge boat to remain afloat and operate. Since a high level of water must remain within the pond in order for the dredge to operate, any pumping of water from the pond will be intermittent and will vary in amount and duration. It is expected that there may be several weeks at a time when there will be no discharge at all. At other times, the water in the pond may be lowered for site development. However, the day to day operation of the dredge does not require regular discharge of�,vater from the pond. The volume of the discharge depends entirely on the capacity of the pump and the duration of the pumping. Based on experience with similar operations, a limit of 12,000 gallons per day is sufficient for an operation of -this size. The N11ning Permit issued by the Land Quality Section gives details of the sediment basin to be utilized for anv discharge of water. The basin is designed for a volume based on a potential of 12.000 gallons per day. However, any water pumped from the dredge pond will originate far from any source of sediment; and will very likely exceed any requirements for clarity even before passing through the basin. When it becomes necessar)' to pump water from the dredge pond, records will be kept of -the volume of water discharged. RECHARGE OF GROUNDNVATER Since this is a "wet" nlrnini) operation, and water will always be maintained %within the pond, it is hi-hly unlikely that any adjacent groundwater levels will be affected. However, in order to assure that adjacent wetlands are not affected during tinges Of pumping; a perimeter "moat" will be excavated between the pond and the wetlands. This will consist of a ditch 12 feet wide, 4 feet deep, and will extend around the northern and southern sides of the pond, between the pond and the wetlands. The ditch will be located 50 feet from the pond, and at least 25 feet from the wetlands. This ditch is shown on the site plan included as part of this Operation and (Monitoring Plan. Whenever an), vvater is to be discharged from the pond, this ditch will be filled with water. Water fiom this ditch -will seep into the sand)' soil; thereby recharging the groundwater in the %vedand area. Water will flow into the ditch from the sediment basin and will subsequently flown out of the ditch into existing ditches within the wetlands, Therefore; the wetlands will also benefit from Some surface water recharge.as well. During times .when there is no discharge from the pond, the ditches will be allowed to maintain any natural water level. MONITORING 1. Any time water is discharged front the pond; the volume of water and date will be recorded. 2. A series of 6 shallow piezonleters will be ]placed within the wetlands as shown on the site.plan. The purpose of the piezonleters is to demonstrate that the pond does not affect the natural hydrology of the site. According to the US Army Carps of Engineers -Wetlands Delineation _Manual (January 1987), natural wetlands hydrology requires '`inundation or saturation to the surface for at least 5% of the growing season". It also states that this inundation or saturation or saturation may be irregular. Our observations of the hydric soil profile of this site confirm that the seasonal high water level is at the surface for at ]east 5% of the growing season and that natural water levels also extend to as much as 3 feet below+ the surface periodically. Fluctuations in this water level are natural and are caused by rainfall events; periods of draught, flooding of the Newport River, seasonal fluctuations.o(-groundwater, absorption by veL33etation, and other factors. These fluctuations are not cyclical and can vary widely. However, in order to maintain ,.vtlands hydrology, it must be shown that the area is "inundated or saturated to the surface continually for at least 5% of the groxving season in most years (50% probabilit. of recurrence)". The piezonleters ,vill be measured monthly and water levels will be recorded. If an)r significant f]uctuation is observed. a comparison will be made to other known data sources such as USGS Ground\vater monitoring in the area, ,veather and drought conditions, The primary purpose: of the piezoineters is to assure that the hydrology of the wetlands is maintained by observing that the site is `inundated or saturated for- at least 5% of the growing season in most years (50% probability of recurrence)" as described by the Army corps of Engineers. 1142 �'4 1]�_5 � � � 114❑ Ll s 1 1 tC2� M r ti �2 vqt" f L of MT �4. `off pG ❑ 'C Mr. James Izzell Carolina Geological Services, Inc. P.O. Box 429 Garner, NC 27529 Dear Mr. Izzell, Michael F. Easley, Governor William G- Ross Jr., Secretary North Carolina Department of Elivironment and Natural Resources October 24, 2006 Alan W. Klimek, P.L. Director Division or Water Quality The Division is in receipt of your correspondence and revised Operation and Monitoring Plan dated October 4, 2006 for the Nine Foot Road Mine #2. 1 have provided the same listed items of concern from the Division's correspondence on August 28, 2006 as a point of reference in responding to your revised plan and comments. Next -to each bulleted item I have attempted to match your response to each, as I understand them from your recent correspondence. How were the wetland boundaries determined? Cover letter/O & M Plan states: The boundaries had been delineated on two separate occasions by qualified wetlands consultants using the Us Army Corps of Engineers Wetland Delineation standards. Division Response: Since Mr. Suggs with U.S. Army Corps of Engineer referenced the utilization of a consultant to determine wetland boundaries, the Division will accept a letter (to be included in your O & M Plan) from the consultants indicating that they possess the qualified skills to determine the boundaries as detailed in the U.S. Army Corps of Engineers Wetland Delineation Manual (January 1987). On July 17, 2006, you advised me by phone that you had not walked any of the ditches that are proposed for use in mine dewatering. Determine the distances each ditch extends into the wetland and the distance from each ditch to the Newport River. Please correct the site map accordingly. Describe how the ditches end. Do they gradually disappear or do they end abruptly? Describe how the discharge to each ditch will accomplish sheet flow to all the adjacent wetlands located around the perimeter of the mine. Describe how the ditches will maintain hydrology for the adjacent wetlands located north of the mine site. Cover letter/O & M Plan states: In the original plan, we proposed to discharge water from the basin into existing ditches. Afield observation showed that there was some connectivity and it was very difficult to determine where the ditches actually end and the natural swales begin. Therefore, we have redesigned the plan to construct new ditches parallel to the edge of the pond and at last 25 feet from the wetlands that will serve to recharge the groundwater. Water pumped from the pond will first pass through the basin, then flood these ditches before passing into the existing ditches utilizing existing drainages. Division Response: You are required to maintain a 50-foot buffer between land disturbances and the wetland boundaries. The ditches (within the mine pit boundaries) must be at least 50 feet (not 25) from any wetlands (per your mining permit). The mine site map indicates the ditches are approximately 50 feet from the wetlands boundaries except for one area on the north side of the mine. Please ensure that a 50- foot buffer between any land disturbance and the wetlands is maintained. The boundaries need to be flagged in order for mining operation personnel digging the ditches to know where those boundaries are so that a 50-foot buffer can be met.

Should check dams be required, their locations should be identified on the site map. • Your O & M Plan should include the volume of water the settling basin can hold and the amount and the rate and duration of discharge anticipated from the settling basin. You mentioned 12,000 gallons per day in an email to Mr. Ed Beck. Provide the calculations (including any assumptions) justifying that estimate and include them in the Plan. Cover Letter/O & M Plan states: It should be emphasized that this is a "wet mining" operation. The "mining area" will actually consist of a deep -water pond with a floating dredge that pumps sand from the bottom of the water. The pond will never be "de -watered" since it is necessary to retain a high level of water within the pond to float the dredge boat. The mining permit issued by the LQS gives details of the sediment basin to be utilized for any discharge of water. The initial pond development requires some storm water and groundwater to be pumped out of the pond area to maintain a dry working area. As soon as the pond is developed to a depth sufficient for floating the dredge boat, it will be allowed to fill with water and the dredging operation will begin. In order to assure that adjacent wetlands are not affected during times of pumping, a perimeter "moat" will be excavated between the pond and the wetlands. This will consist of a ditch 12 feet wide, 4 feet deep and will extend around the northern and southern sides of the pond, between the pond and the wetlands. Division Response: This response refers to DLQ plans, which DWQ does not have. The site map accompanying your cover letter and O & M Plan shows a picture of a pond but is not to scale and therefore inadequate for determining volume from the diagram. The picture at the upper left hand corner indicates a rock dam structure with a volume of 7200 cubic feet or approximately 50,000 gallons. Your site map shows two basins if both are designed according to the diagram, affords storage of 100,000 gallons total. Utilizing the proposed ditches to receive wastewater pumped from the settling basins provides a better method of introducing wastewater to the surrounding wetlands. It should afford better settling time and lower velocity for the discharge if/when introduced to the wetlands. Crude calculations from the design of the ditches suggest they should be able to hold (roughly) 90,000 gallons of water. Once full, if the proposed ditches can distribute water by sheet flow, they would discharge less than an inch of water per day along 1900 feet (estimated from the O & M map where V=100'). Please take time to read the water quality standards as they pertain to wetlands. The water quality standards for wetlands can be found in the North Carolina Administrative Code 15 A NCAC 02B.0231. When you read these standards you will realize there is more to wetlands protection than just hydrology. I have attache_ d a copy of those standards for your reference and convenience. • The map shows one settling basin east of the ditch that cuts through the narrowest portion of the mine site. During a visit to the mine, a settling pond was seen located West of the ditch. Will this pond remain on site? Will it be used as a settling basin as well? If it will be used as a settling basin please include it on the site map. Division Response: The map provided with the revised O & M Plan shows two settling basins used to recharge the proposed ditches. I will assume the design for both are the same as those provided on the map. • The O & M Plan requires detailed plans to maintain the surrounding hydrology and the respective monitoring to demonstrate compliance. The Plan states that a'series of 6 shallow monitoring wells will be installed at the site, located 25 feet within the wetlands and spaced no greater than 300 feet apart. Please include the locations of wells on the site map in order that their locations can be seen relative to the adjacent wetlands bordering the mine site. O & M Plan (Monitoring) states: The primary purpose of the piezometers is to assure that the hydrology of the wetlands is maintained by observing that the site is "inundated or saturated for at least 5 % of the Page three NCG020683 growing season in most years as described by the Army Corps of Engineers. O & M Plan provided on July 17, 2006 indicates monitoring of the wells will be conducted monthly. Wells will be constructed of 2" diameter PVC, with standard slotted sections and casing. Total depth will extend to approximately 5 feet below existing static water level, and the screened interval will be sealed from surface water by a bentonite plug. Overall condition of the wetland plants and soil conditions will be monitored on a monthly basis. Division Response: The map provided with the revised O & M Plan shows the locations of each monitoring well. Monitoring wells should be in place before any dewatering from the site occurs. Prior to dewatering, the hydrology of the surrounding wetlands should be established based upon data collected from the monitoring wells prior to dewatering. Data from the level of water in the monitoring wells must be well documented and available for review by Division Representatives upon inspection. The Plan states that the monitoring wells will be 5 feet below the static water level, it states also that if the well levels drop 3 feet or more, all dewatering in the excavation will be suspended until groundwater levels have recovered to natural levels. Be advised, to protect a wetland means to protect its hydrology. A drop of 3 feet in the water table could be detrimental to the wetlands. The seasonal high water table in the wetlands must be determined either by a registered soil scientist or through long term monitoring. Those levels should be documented and used as a benchmark to maintain throughout the wet and growing season. Monitoring the overall condition of the vegetation while mining activities occur would be beneficial. Should impacts in the adjacent wetlands occur, what contingency backup plan will you utilize? O & M plan (July 2006).states that if any significant impact is noted in the existing plants or soil conditions, dewatering activity will be suspended until recovery is noted Division Response: Division concurs that discontinuing dewatering until recovery is noted is appropriate. Likewise, inundation of the wetlands from dewatering and not from natural conditions (heavy rain, Newport River flooding, and seasonal fluctuations in the groundwater table) will be considered an impact and dewatering activities will have to cease until natural conditions return. • The Plan states that the monitoring wells will be monitored once per month. This may be adequate, however, should monitoring suggest significant changes in the wetland hydrology, more frequent monitoring will be required. O & M plan (July 2006) states that if any significant impact is noted in the existing plants or soil conditions, dewatering activity will be suspended until recovery is noted Division Response: Immediately discontinuing the activity causing the impact is acceptable and does not require more frequent monitoring. The NCG020000 Permit also specifies analytical and qualitative monitoring for storm water discharges from land disturbance and process areas, effluent limitations and monitoring requirements for mine dewatering wastewater and process wastewater and monitoring requirements for wastewater from sand and or gravel mining. Your plan did not include any of this information. Please revise your plan to include the sampiinglmonitoring requirements as specified in the NCG020000 permit. cf Page three NCG020683 The Division will give approval for mining activities to be conducted prior to a complete O & M Plan with the understanding that your O & M Plan will be revised to include all the pertinent components and that upon inspection by Division Representatives, the permittee will produce a complete and satisfactory O & M plan including all analytical and qualitative monitoring data and records required by the plan and the NCG020000 permit. Any areas that are deficient will be considered a violation to the NCG020000 Permit. Should you require any additional help, please do not hesitate to contact me at 910-796-7343.

After receiving your correspondence and review of our original plan, we have tried to provide the additional information that you have requested and have made some changes to reflect your concerns. It is the sincere desire of Mr. Garner to protect the environment and to remain in compliance with all permit requirements. I hope that this revised plan will demonstrate his willingness to take all necessary measures to protect the wetlands on his property. In your letter of August 28, you ask several questions and express concerns relating to the site that need to be addressed. First, you ask how the wetland boundaries were determined. The wetlands were delineated on two different occasions by qualified wetlands consultants using the US Army Corps of Engineers Wetland Delineation standards, specifically as detailed in the "Corps of Engineers Wetland Delineation Manual" (January 1987). This delineation was done before the site was designed to assure that no land disturbance activities would impact any wetlands: The Land Quality Section requires a minimum 50-foot buffer between any Land Disturbance and any wetland. To be conservative, the site was designed to remain entirely within the cleared field, 50 feet from any wooded vegetation. However, the actual wetland limit is 75 to over 100 feet from the limits of land disturbance. Since the site was located so far from the actual wetlands limits, the US Army Corps of Engineers determined that they had no jurisdiction within the site. P.O. BOX 429, GARNER, NC 27529 (9 1 9)779-001 7 Fax: (91 9)779-7227 OFFICES AT 10 1 WEST MAIN STREET, GARNER, NC Division of Water Quality Page 2 Many of the concerns in your letter indicate that there may be a misunderstanding of the actual design and operation of this facility. It should be emphasized that this is a "wet mining' operation. The "mining area" will actually consist of a deep -water pond with a floating dredge that pumps sand from the bottom of the water. The pond will never be "de -watered" since it is necessary to retain a high level of water within the pond to float the dredge boat. Water may be pumped from the pond occasionally to work the slopes or obtain material from- the deeper sections, but a high level of water will always remain within the pond. Therefore, pumping will not be required for the day to day operation of this facility. This is the most "environmentally friendly" mining method possible, since it has virtually no impact on surrounding groundwater levels. While we understand the need to assure that any adjacent wetlands are protected, we do not see how a pond, which retains a high level of water, will have any impact at all on surrounding groundwater levels or wetlands. In fact, it has been observed in the initial development of this pond that groundwater levels have actually increased! It is highly unlikely that a pond of water will have any impact at all on surrounding wetlands. However, since your office has expressed a concern that the pond may have a negative impact on the wetlands, we have redesigned the Operation and Monitoring plan to address your concerns. In the original plan, we proposed to discharge water from the basin into existing ditches. We agree with your observations that the ditches are somewhat complex. A field observation showed that there was some connectivity and it was very difficult to determine where the ditches actually end and the natural swales begin. Therefore, we have redesigned the plan to construct new ditches parallel to the edge of the pond and at least 25 feet from the wetlands that will serve to recharge the, groundwater. Water pumped from the pond will first pass through the basin, then flood these ditches before passing into the existing ditches utilizing existing drainages. The water contained within these ditches will seep into the sandy soil and constantly recharge the groundwater. The site will also be monitored by keeping records of dates and volume of water that may be pumped from the pond. Keep in mind that pumping from the pond will be intermittent and vary in amount and duration. It is expected that there may be several weeks at a time when no pumping will be required at all. At other times, the water in the pond may be lowered for site development. However, the day to day operation of this site does not require any pumping from the pond. In addition, a series of piezometers will be placed within the wetlands to monitor the hydrology of the wetlands and insure that the site remains in compliance. Division of Water Quality Page 3 1 must again express Mr. Garner's frustration at the time that it has taken for this review. This is a "wet mining" operation utilizing a hydraulic dredge in a pond which retains a high level of water. It is our position that this pond simply could not have any negative impact on surrounding groundwater levels or wetlands. In fact, it can be shown that the initial stages of this operation have actually raised the groundwater levels adjacent to the pond. However, since there will occasionally be some lowering of the water level within the pond, we have designed the Operation and Monitoring plan to provide the necessary protection of the surrounding wetlands. I ask that you review this information as soon as possible so that Mr. Garner can continue his operation. Of course, if you have any questions, please contact me. Sincerely, �w &AaA James C.

Carteret County, NC The purpose of this plan is to provide the necessary precautions to prevent any impact on adjacent wetlands from discharges from the dredge pond. The plan provides protection to the wetlands by providing a steady recharge of water as well as regular monitoring to demonstrate compliance. It should be emphasized that this sand mine is a "wet mining" operation, and will use a hydraulic dredge in its operation, and therefore will not pump water from the pond on a continual basis. The dredge consists of a boat with a pump that removes sand from the bottom of the pond to a small processing plant adjacent to the pond. Water drains from the sand pile, and is recycled back into the pond, maintaining the water level within the pond. In order for this dredge to operate, a high level of natural groundwater must remain within the pond at all times. Since a high level of water will remain within the pond; it is highly unlikely that the natural groundwater level adjacent to the pond will be affected at all. However, in the initial development of the pond, it is necessary to discharge some water to maintain a dry working area. After the pond is developed to a sufficient depth for floating the dredge boat, the area will be allowed to fill with groundwater for normal operation. As the pond is developed, there may occasionally be times when it is necessary to discharge some water. However, since the mining method will be by hydraulic dredge, it will always be necessary to maintain a high level of natural groundwater within the pond. This is the most environmentally friendly mining method possible, since it is virtually impossible to discharge any sediment, it maintains natural groundwater levels, and it greatly limits dust since it is a "wet" operation. OPERATION This Wet Mining operation utilizes a floating hydraulic dredge boat to pump sand from the pond to a small processing area adjacent to the pond. Water from the sand will naturally drain back into the pond, maintaining the water level. The initial pond development requires some stormwater and groundwater to be pumped out of the pond area to maintain a dry working area. As soon as the pond is developed to a depth sufficient for floating the dredge boat, it will be allowed to fill with water and the dredging operation will begin. As the pond is developed with the dredge, it will occasionally be necessary to discharge some water from the pond. However, the water level will always remain deep enough to allow the dredge boat to remain afloat and operate. Since a high level of water must remain within the pond in order for the dredge to operate, any pumping of water from the pond will be intermittent and will vary in amount and duration. It is expected that there may be several weeks at a time when there will be no discharge at all. At other times, the water in the pond may be lowered for site development. However, the day to day operation of the dredge does not require regular discharge of water from the pond. The volume of the discharge depends entirely on the capacity of the pump and the duration of the pumping. Based on experience with similar operations, a limit of 12,000 gallons per day is sufficient for an operation of this size. The Mining Permit issued by the Land Quality Section gives details of the sediment basin to be utilized for any discharge of water. The basin is designed for a volume based on a potential of 12,000 gallons per day. However, any water pumped from the dredge pond will originate far from any source of sediment, and will very likely exceed any requirements for clarity even before passing through the basin. When it becomes necessary to pump water from the dredge pond, records will be kept of the volume of water discharged. RECHARGE OF GROUNDWATER Since this is a "wet" mining operation, and water will always be maintained within the pond, it is highly unlikely that any adjacent groundwater levels will be affected. However, in order to assure that adjacent wetlands are not affected during times of pumping, a perimeter "moat" will be excavated between the pond and the wetlands. This will consist of a ditch 12 feet wide, 4 feet deep, and will extend around the northern and southern sides of the pond, between the pond and the wetlands. The ditch will be located 50 feet from the pond, and at least 25 feet from the wetlands. This ditch is shown on the site plan included as part of this Operation and Monitoring Plan. Whenever any water is to be discharged from the pond, this ditch will be filled with water. Water from this ditch will seep into the sandy soil, thereby recharging the groundwater in the wetland area. Water will flow into the ditch from the sediment basin and will subsequently flow out of the ditch into existing ditches within the wetlands. Therefore, the wetlands will also benefit from some surface water recharge as well. During times when there is no discharge from the pond, the ditches will be allowed to maintain any natural water level. MONITORING 1. Any time water is discharged from the pond, the volume of water and date will be recorded. 2. A series of 6 shallow piezometers will be placed within the wetlands as shown on the site plan. The purpose of the piezometers is to demonstrate that the pond does not _affect the natural hydrology of the site. According to the US Army Corps of Engineers Wetlands Delineation Manual (January 1987), natural wetlands hydrology requires "inundation or saturation to the surface for at least 5% of the growing season". It also states that this inundation or saturation or saturation may be irregular. Our observations of the hydric soil profile of this site confirm that the seasonal high water level is at the surface for at least 5% of the growing season and that natural, water levels also.extend to as much as 3 feet below the surface periodically. Fluctuations in this water level are natural and are caused by rainfall events, periods of draught, flooding of the Newport River, seasonal fluctuations of groundwater, absorption by vegetation, and other factors. These fluctuations are not cyclical and can vary widely. However, in order to maintain wetlands hydrology, it must be shown that the area is "inundated or saturated to the surface continually for at least 5% of the growing season in most years (50% probability of recurrence)". The piezometers will be measured monthly and water levels will be recorded. If any significant fluctuation is observed, a comparison will be made to other known data sources such as USGS Groundwater monitoring in the area, weather and drought conditions. The primary purpose of the piezometers is to assure that the hydrology of the wetlands is maintained by observing that the site is "inundated or saturated for at least 5% of the growing season in most years (50% probability of recurrence)" as described by the Army corps of Engineers.

After the pond is developed to a sufficient depth for floating the dredge boat, the area will be allowed to fill with groundwater for normal operation. As the pond is developed, there may occasionally be times when it is necessary to discharge some water. However, since the mining method will be by hydraulic dredge, it will always be necessary, to maintain a high level of' natural groundwater within the pond. This is the most environmentally friendly mining method possible, since it is virtually impossible to discharge any sediment; it maintains natural uoundwater levels, and it greatly limits dust since it is a "wet" operation. OPERATION This Wet Mining operation utilizes a floating hydraulic dredge boat to pump sand from the pond to a small processing area adjacent to the pond. Water from the sand will naturally drain back into the pond; maintaining the crater level. The initial pond development requires sorne stormwater and groundwater to be pumped out of the pond area to maintain a dry working area. As soon as the pond is developed to a depth sufficient for floating the dredge boat; it will be allowed to fill with water and the dredging operation will begin. As the pond is developed with the dredge, it will occasionally be necessary to discharge some water from the pond. However, the water level will always remain deep enough to allow the dredge boat to remain afloat and operate. Since a high level of water must remain within the pond in order for the dredge to operate; any pumping of water from the pond will be intermittent and will vary in amount and duration. It is expected that there may be several weeks at a time when there will be no discharge at all. At other times, the water in the pond may be lowered for site development. However, the day to day operation of the dredge does not require regular discharge of water from the pond. The volume of the discharge depends entirely on the capacity of the pump and the duration of the pumping. Based on experience with similar operations, a limit of 12,000 gallons per day is sufficient for an operation of this size. The Mining Permit issued by the Land Quality Section gives details of the sediment basin to be utilized for any discharge of water. The basin is designed for a volume based on a potential of 12,000 gallons per day. I-IoNvever, any water pumped from the dredge pond will originate far from any source of sediment, and will very_ likely exceed any requirements for clarity even before passing through the basin. When it becomes necessary to pump water from the dredge pond, records will be kept of the volume of «later discharged. RECHARGE OF GROUND«'ATER Since this is a "wet" mining operation; and water will always be maintained Within the pond, it is highly unlikely that any adjacent groundwater levels will be affected. However, in order to assure that adjacent wetlands are not affected during times of pumping, a perimeter "moat" will be excavated between the pond and the wetlands. This will consist of a ditch 12 feet wide; 4 feet deep, and will extend around the northern and southern sides of the pond; between the pond and the wetlands. The ditch wil l be located 50 feet from the pond; and at least 25 feet from the wetlands. This ditch is shown on the site plan included as part of this Operation and Monitoring Plan. Whenever any water is to be discharged from the pond; this ditch will be filled with water. Water frorn this ditch will seep into the sandy soil, thereby recharging the groundwater in the wetland area. Water will flow into the ditch from the sediment basin and will subsequently flow out of the ditch into existing ditches within the wetlands. Therefore; the wetlands will also benefit from some surface water recharge as well. During times when there is no discharge from the pond, the ditches will be allowed to maintain any natural water level. MONITORING 1. Any time water is discharged from the pond, the volume of water and date will be recorded. 2. A series of 6 shallow piezometers will be placed within the wetlands as shown on the site plan. The purpose of the piezometers is to demonstrate that the pond does not affect the natural hydrology of the site. According to the US Army Corps of Engineers Wetlands Delineation Manual (January 1987), natural wetlands hydrology requires "inundation or saturation to the surface for at least 5% of the growing season". It also states that this inundation or saturation or saturation may be irregular. Our observations of the hydric soil profile of this site confirm that the seasonal high water level is at the surface for at least 5% of the growing season and that natural water levels also extend to as much as 3 feet below the surface periodically. Fluctuations in this water level are natural and are caused by rainfall events, periods of draught, flooding of the Newport River, seasonal fluctuations of groundwater, absorption by vegetation, and other factors. These fluctuations are not cyclical and can vary widely. However, in order to maintain wetlands hydrology; it must be shown that the area is "inundated or saturated to the surface continually for at least 5% of the growing season in most years (50% probability of recurrence)". The piezometers will be measured monthly and water levels will be recorded. If any significant fluctuation is observed, a comparison will be made to other known data sources such as USGS Ground,yater monitoring in the area, weather and drought conditions. The primary purpose of the piezometers is to assure that the hydrology of the wetlands is maintained by observing that the site is "inundated or saturated for at least 5% of the growing season in most years (50% probability of recurrence)" as described by the Army corps of L-ngineers.

The site (sched. to start April 2006?) will discharge stormwater and mining dewatering water into the Newport River (Class C segment) through a settling basin, *and into wetlands* adjacent to the river. The Mining Permit (16-61) was issued from DLR back in November 2005. The NOT is attached; however, there is a larger map that I couldn't scan -- it will be on it's way to you via interoffice mail. At the bottom of the map, a note says "Modification Request, June 2006: Excess stormwater or groundwater will be pumped out of the mining area. A basin has been added within the previously approved mining area. The only discharge of any water will be by pumping through this basin. Discharges will average less than 12,000 gallons per day. All stormwater will be contained within the mining area until it is pumped out." Does the Wilmington Regional Office have any concerns about issuing this facility a COC for this general permit? Obviously, there are potential impacts to wetlands, so I'm not sure if the Region has already been working with this permittee regarding an Operation and Monitoring plan. Normally if we don't receive any objections, we'll issue the COC in 30 days, but I'll wait to hear from you on this one given the wetlands issues.

She made an appointment to be at the site on Friday afternoon, August 11 at approximately 3:00 pm. August 11: Mr. Morgan Garner arrives at the site at 1:00 and gaits until 6:00 for Ms. Willis, who never arrived or called me or Mr. Garner informing us of her change in plans. I telephoned Ms. Willis yesterday, leaving her a message inquiring about the site visit and the progress of the approval of the Operation and Monitoring Plan. She returned my call late yesterday with a message informing us that she did not have time to visit the site on the 1 V as planned. She went on to explain that she was rev-ie«ing another mining operation that had been waiting since 2005 .for approval. She also requested that we "take photographs" of the site and the ditches that discharge into the wetlands, and that we prepare an "Operation and Monitoring Plan"_ She has expressed some concern that the discharge may actually bypass the wetlands and drain directly into the Newport River. The Newport River is over 500 feet a-,vay from the discharge point where the ditches discharge into the wetland. In designing the "Operation and Monitoring Plan'`; ive designed a plan that forces -the discharge water to flow into the wetlands for recharge of the near -surface water. The ditches selected for this purpose were chosen to maximize this recharge. The ditches do not flow into the Newport River. The ditches end within the wetlands, and all water in the ditches will flow by sheet flow back into the wetlands area. Further, the plan calls for regular monitoring of the water level and the health and vitality of the wetland vegetation. This monitoring plan should demonstrate the effectiveness of the recharge and prevent any dewatering of the wetlands. I hope you can understand my client's frustration at this point. He has been forced to shut clown his business for several months, while he has responded to every request as quickly and completely as possible. We have submitted the Operation and Monitoring Plan, which followed the guidelines in the language of the General Pennit and followed the guidance from conversations with you and Nis. Willis. At Ms. Willis' request, we had the US Army Corps of Engineers review the plans; and they have submitted their position to your office. And now we are being asked to submit photographs of the site, which has been inspected numerous times in recent weeks by a variety of agencies and by Ms. Willis herself. Further, we are now asked to submit another Operation and Monitoring Plan with no guidance on how our original plan is inadequate.

As you may recall, Garner Construction Company received a General Stormwater Permit from the Division of Water Quality dated .Tune 30. 2006 to allow them to discharge Stormwater and groundwater from their sand mine. As stated in the cover letter, the mine may have "the potential to impact adjacent wetlands". Therefore, in accordance with the permit requirements, we are herein submitting an Operation and Monitoring Plan. The purpose of this plan is to take every precaution to prevent any impact on adjacent wetlands and to continually monitor site conditions before any impact occurs. The key to minimizing the impact on the wetlands at this site is a recharge of the groundwater. As indicated on the Mine Plan, the Stormwater and groundwater that will be pumped from the pit will first pass through a sediment basin to remove sediment from the water. After leaving this basin it will flow through an existing ditch directly into the adjacent wetlands. All water pumped from this pit will flow by sheet flow into the wetlands, providing a constant recharge during times of pit dewatering. In order to monitor any potential impact on the wetlands; a series of shallow monitoring wells will be constructed near the edge of the wetlands. Regular measurement of the groundwater will assure that the above described recharge is effectively maintaining the groundwater and to demonstrate compliance. ��: � � �� . 8 f � l o e � ► �. do 1��-►ti •, R�.o� �, vrw� ec �u�-r� �-o-�t � 4.��.

Thus, the wetlands will be constantly recharged during times of pit dewatering. 2. Monitoring: In order to monitor any potential impact to the near -surface groundwater, a total of 6 monitoring wells will be installed at the site. These wells will be located 25 feet within the wetlands (75 feet from the excavation), and spaced no greater than 300 feet apart. They will be constructed of 2" diameter PVC, with standard slotted sections and casing. The total depth will extend to approximately 5 feet below existing static water level, and the screened interval will be sealed from surface water by a bentonite plug. The wells will be constructed in accordance with NCDENR Well Construction standards. Water levels in these wells will be measured once a month. According to observations at this site, current groundwater levels are within 2 feet of the surface. While some minor fluctuations are anticipated, any significant drop in the near -surface water levels will be noted. If the groundwater levels drop 3 feet or more, all dewatering in the excavation will be suspended until groundwater levels have recovered to natural levels. In addition, the overall condition of the wetland plants and soil conditions will be monitored on a monthly basis. if any significant impact is noted in the existing plants or soil conditions, dewatering activity will be suspended until recovery is noted. All monitoring records will be maintained and available for review upon request. JUL-18-06 TUE 09:28 AM CAROLINA.GEOLOGICAL 9197797227 To: Carolina Geological Services, Inc. P.O.

Hi Ed, We've received an NOI from Garner Construction for Nine Foot Mine #2 Mine in Newport (Carteret County) for coverage of their sand mine under NCG02 (Mining 5W/WW permit). The site (sched. to start April 2006?) will discharge stormwater and mining dewatering water into the Newport River (Class C segment) through a settling basin, *and into wetlands* adjacent to the river. The Mining Permit (16-61) was issued from DLR back in November 2005. The NOI is attached; however, there is a larger map that I couldn't scan -- it will be on it's way to you via interoffice mail. At the bottom of the map, a note says "Modification Request, June 2006: Excess stormwater or groundwater will be pumped out of the mining area. A basin has been added within the previously approved mining area. The only discharge of any water will be by pumping through this basin. Discharges will average less than 12,000 gallons per day. All stormwater will be contained within the mining area until it is pumped out." Does the Wilmington Regional Office have any concerns about issuing this facility a COC for this general permit? Obviously, there are potential impacts to wetlands, so I'm not sure if the Region has already been working with this permittee regarding an Operation and Monitoring plan. Normally if we don't receive any objections, we'll issue the COC in 30 days, but I'll wait to hear from you on this one given the wetlands issues.

Mine Site Map should clearly show: A. The areas where the excavated sand (mechanical removal) will be stored prior to removal offsite and where the dredged sand will be stored for dewatering. Show all haul roads. B. Clarify what the dewatering area indicated on the map north of pit 2 represents. C. Identify the outfall location for any point source discharge from the mine site. 2. The attached correspondence from the USACOE, verifying wetland boundaries, was strictly commenting on a 12 acre mine site. Does Pit 1 and Pit 2 equal 12 acres? Please indicate the size of the excavation areas in acres. 3. The O & M plan should identify a means to hydrate wetland A and B since digging a 40' deep pit within 50' of the wetland will likely impact the wetland. The monitoring wells should be utilized to demonstrate the effectiveness of the hydration techniques. 4. Dewatering activity: A. Indicate pump rates for dewatering activities. Identify the pump rate for the dewatering activity when mechanical pit excavation is being used and what the pump rate will be for the dredging operation. Describe the pumping schedules (8 hr/d, 12 hr/d, continual). The estimation of flow should be based upon a hydrogeologic study to determine conductivities of formations beneath the site. B. The temporary settling basin appears to be small in comparison to the size of the pits excavated. Provide the size of the temporary settling basin and existing pits. Please provide calculations identifying the detention time and daily flow rate from the settling basin based on the pump rate for dewatering the excavation of pits and pump rate of the dredging operation. Comment an storage capacity of the sediment basin. C. Discuss the ability for the temporary settling basin to provide adequate detention time to meet the discharge limits for TSS of 25 mglL (monthly average) and 45 mg/l. (daily maximum). The proposal mentions the use of Pit 2 for dewatering activities from Pit 3. D. The sequence of excavation section needs more illustration, the text is not clear enough to visualize. F. }low will dredged sand be managed? Discuss dewatering. The proposal indicates the dredged sand would be put in the vacant pit (which will likely be full of water unless aggressively dewatered). Please clarify. F. Proposal indicates stormwater will not be discharged via the sediment basin. How will stormwater be managed? 3. Monitoring activities: A. Clearly spell out the monitoring requirements in the O & M plan for mine dewatering and stormwater _ discharges from the mine site. B. Wetland monitoring should be conducted at least three days a week at first for at least the first year. This requirement can be discussed after a year's worth of data is generated that indicates a less frequent schedule is reasonable. More frequent monitoring of the wells in the adjacent wetlands will identify impacts from dewatering activities immediately and provide immediate indications of whether the attempts to maintain hydrology in the wetlands is effective.

Nl RECEIVED APR 0 5 2011 BY: This STORMWATER POLLUTION AND PREVENTION PLAN was prepared in accordance with the requirements specified in the National Pollutant Discharge Elimination System (NPDES) General Permit for.Mining (NCG020), and specifically as applied in the Certificate of Coverage for this location: Garner Construction Co. Inc. Nine Foot Mine # 2 Certificate of Coverage NCG020683 Nine Foot Road Newport, NC Lat. 34.7925 Long.—76.8946 This plan is designed to satisfy the requirements of Part I11, Section A of the NPDES General Permit NCG020.

More detailed information, such as the name of the receiving water and the longitude 1 latitude of the points of discharge is shown on the site map in part 1(c). , �j 1 b. Narrative description of practices, processes, and potential pollutants This operation is classified as a Sand & Gravel Mine (SIC code 1440). The primary processes employed at this location include excavation of soil from the surface, excavating sand and gravel from the mining area, transporting the sand and gravel from the mining area to the processing plant, washing and sorting the sand and gravel, stockpiling the finished products, and loading the finished product for transportation away from the site. At each point in this process, controls are in place to prevent any potential pollutants from leaving the site via stormwater. These controls are specifically designed in accordance with the Sediment and Erosion Control Plan as approved by the NCDENR, Division of Land Resources (see part 2 of this Plan). The excavation of soil, sand, and gravel is confined to the designated "Mining Area" on the Mine Plan. The primary potential pollutant that is generated by this activity is sediment. The mining area itself acts as the sediment and erosion control structure by holding the stormwater within the pit. There is no discharge from the mining area during any storm event.- The only discharge is by pumping after the sediment has been allowed to settle out. Any water that is discharged from this area leaves the site via sample point NPDES 01, and is monitored as required. The excavated soil (overburden) remains within the mining area or is placed within the perimeter berms. This material is sloped and seeded to prevent erosion. The sand and gravel from the mining area is hauled to the processing plant for washing and sizing. This process occasionally generates some fine rock particles and dust. A dust -suppression system using water and covered equipment prevents this material from becoming airborne. Much of the wash and dust suppression water adheres to the sand and gravel and acts to further control airborne dust. After the sand and gravel is mined, it is stockpiled in areas designated as "stockpile area". The sand and gravel remains in piles until it is loaded onto customer trucks and removed from site. Some sediment is generated by stormwater falling onto the stockpiles, as well as runoff from traffic areas. All of the stormwater from these areas flows back into the pond area and is held there to remove the sediment. In each phase of the processes described above the primary potential pollutant that could be expected to be present in any stormwater discharge from any outfall is sediment, in the form of turbidity, and suspended or settlable solids. These parameters are monitored as required in this permit. Several pieces of heavy equipment are utilized in each phase of this process. This equipment has the potential to leak fuel, fluids, coolants, or oil at any point. This is a very rare occurrence, and is discussed more thoroughly in parts IV and V of this plan. With effective preventive maintenance and a plan to control and clean up any spills, there is virtually no chance of these substances becoming a potentially discharged pollutant. 1d. List of significant spills or leaks of pollutants during past 3 years Date: Description: Corrective Action: Date: Description: Corrective Action: Attach additional sheets as necessary. Retain records for 3 years. 1e. Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. There are no stormwater outfalls in this site. All stormwater is retained within the pond and/or mining area. Therefore, there are no non-stormwater discharges from the site. The signed Certification Statement is found in the Annual Review and Update Checklist in Part 8 of this Plan, 2. Erosion and Sediment Control This site has an approved Erosion and Sediment Control Plan, detailed in the site plans and information submitted as part of the North Carolina Mining Permit application. Mining Permit # 16-61 was approved and issued by the NCDENR — Division of Land Resources on November 17, 2005, and will expire on November 17, 2015. All management practices and erosion and sedimentation control measures that are included in this permit have been implemented at this site. This site remains in compliance with the Mining Permit, and there has been no deviation from the approved plan. Any changes or modifications of the original plan are submitted as a modification request to the Division of Land Resources before such changes are implemented.. All erosion and sediment controls are inspected on a weekly basis. A signed copy of the issued Mining Permit including the approved erosion and sedimentation control measures and the reclamation plan is included in this plan. Further data, including design calculations, is on file at the Central Office and can be examined upon request. Copy of NC Mining Permit 16-61 — in Appendix 3 Complete site plans included as Appendix 1 3. Stormwater Management Plan This site employs Best Management Practices (BMP's) to control or minimize exposure of significant materials to Stormwater. The approved Erosion and Sedimentation Control Plan manages stormwater runoff and runon in a manner that reduces or eliminates pollutants in stormwater discharges leaving the site. BMPs may take the form of a process, activity, or physical structure. This Stormwater Management Plan describes Best Management Practices that were used in the original construction of this facility, BMPs that have been used in modifications since the original construction, BMPs that should be followed for any future modifications, and BMP activities that are used for ongoing inspections and maintenance. The NPDES Permit requires specific monitoring and sampling of stormwater and mine dewatering. The purpose of this monitoring and sampling is to evaluate the effectiveness of the Stormwater Management Plan. The monitoring and sampling requirements are described in the text of the NPDES Permit as referenced below; 3a. Management of Stormwater Runoff and Runon Stormwater BMP's are employed and maintained for mine excavation and disturbance areas, process areas, and other areas associated with mining. In addition, controls are in place to limit or isolate selected land disturbance and process areas and limit the amount of offsite stormwater runon to these areas. Specific details of each BMP control feature are shown in the enclosed Erosion and Sediment Control plan associated with the NC Mining Permit. (see appendix 1). In general, this site is designed to limit stormwater runon with barriers and diversions such as berms, vegetative swales, and natural topography. All stormwater that falls within a disturbed area is diverted to the mining area 1 pond. Land disturbance is kept at a minimum to reduce overall impact. 31b. BMP Controls Inspection and Maintenance All stormwater BMP controls are to be inspected at least once every seven calendar days and within 24 hours after any storm event that results in a discharge. BMP's shall be operated and maintained at the designed efficiency. BMP's must be cleaned out when sediment storage capacity is at 50% volume. If visible sediment is leaving the property, corrective 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. A log shall be kept of all inspections, maintenance, repairs, as well as any visible sedimentation leaving the site. BMP Inspection logs included as Appendix 2 3c. Secondary Containment Requirements. and Records There are no fuels or other potential contaminants stored onsite. 3.d Monitoring Requirements: The following is a written guide for compliance with all Mine Dewatering Discharge Monitoring. It is the responsibility of the Site Manager to make sure that all monitoring and sampling is being performed on schedule. Monitoring Requirements for Mine Dewatering Water that is pumped from the pit and discharged from the site is classified as "Mine Dewatering Wastewater' and is subject to monitoring and sampling as described in Part III, Section E — 1. Frequency: Samples must be taken on a quarterly basis. If any quarterly sample is missed, or if any tested parameter limitation is exceeded, then samples must be taken on a monthly basis for the remaining permit term (through Dec 31, 2014) Sample Location: Samples should be taken from the ditch before the discharged water passes into the wooded area. Analytical Monitoring Required: Analytical monitoring requirements are described in Part 111, Section E, Table 7. For Nine Foot Road Mine #2, the discharge must be monitored for pH, Settleable Solids, Total Suspended Solids, Turbidity, and Total Flow. General sampling protocol: Sample containers should be obtained from the designated laboratory prior to sampling the discharge. The containers should be labeled in accordance with the laboratory requirements. The sample should be labeled "Nine Foot Mine #2 NPDES 0 1 " with the date and time of sampling as well as the requested analysis. All samples should be placed on ice in a cooler so that the temperature of the sample is a minimum of 4 degrees C upon arrival at the lab. A Chain of Custody form should be submitted to the lab with all samples A written log should be kept for all sampling activities. The fog should include the date and time of sample. It should also include a record of daily pH meter calibrations, a record of a pH neutral measurement, the pH of the sample, the temperature of the sample, and the measurement of the flow of water (see below). Monitoring Instructions for Individual Parameters: pH: The pH of the water sample must be taken immediately, or within 15 minutes of taking the sample. A Certified pH meter must be used to measure pKin accordance with the manufacturer's guidelines. pH meters must be Certified by NCDENR on a regular basis. The pH meter must be calibrated daily following manufacturer's guidelines before any samples are measured. A record of the calibrations should be entered into the log. In addition, a pH neutral buffer should be measured by the meter immediately before the sample is measured. The temperature of the sample must also be recorded in the log. Total Flow: A flow meter should be utilized to measure the flow of water from the discharge. This flow rate can be calculated into a volume rate using standard calculations. Alternatively, the flow can be estimated from pump performance data. If the flow is too small to be accurately measured, an estimated flow rate can be entered into the log. If the flow is very small, the rate can be entered as "trace". Turbidity, Total Suspended Solids, Settleable Solids: Each of these parameters must be measured by a Certified Lab. Containers must be obtained from the lab as described above. Samples should be submitted to the Lab within 24 hours or according to lab requirements. Requirements for Monitoring Records and Reporting Sampling Log: A written log must be kept of all sampling and monitoring activities. The field inspector is responsible for keeping this written log, and should produce it on demand by NCDENR. This log should include at a minimum; - date, time, and sample location - record of field analysis (pH, temperature, flow, etc) - analytical samples taken - calibration of pH meter or other instruments - pH neutral checks Recording Results: The Site Manager is responsible for maintaining a permanent record of each monitoring and sampling event. The field inspectors should provide the information from his written log to the Site Manager on a quarterly basis. In addition, the permanent record should include all analytical results from the laboratory reports. The reports and associated chain -of -custody forms should be kept on file. Copies of all reports sent to the NCDENR Division of Water Quality should also be kept on file. Copies of all of the above information should be provided to the Site Manager on a regular basis and kept in the Stormwater Pollution Prevention Plan notebook. All of the records should be kept on file for a minimum of 5 years. Discharge Monitoring Reports: All monitoring data as described above shall be recorded on forms provided by the NCDENR and provided herein. Data from Mine Dewatering Wastewater must be recorded on the form entitled ANNUAL SUMMARY DMR — WASTEWATER. This form must be completed by the Site Manager with data from the above described records. This form must be submitted to the NCDENR Division of Water Quality (DWQ) by March 1 of each for the previous year's monitoring. However, if any samples violate a wastewater effluent limit or benchmark limit, a DMR report must be submitted within 30 days from the date that the Site Manager receives the sampling results from the laboratory. When no discharge has occurred from the site during the report period, the Site Manager should enter "NO FLOW" or "NO DISCHARGE" in the permanent record. This should be noted ANNUAL SUMMARY DMR's. Noncompliance with Monitoring Schedule Requirements It is the responsibility of the Site Manager to make sure that all wastewater discharges are monitored according to the above requirements. He should be in contact with the field inspector to make sure that they schedule the required monitoring and sampling to be in compliance with the NPDES Permit requirements. Mine Dewatering Wastewater: Pit discharge water must be monitored (sampled) on a quarterly basis. If any quarterly sample is missed, then the monitoring (sampling) schedule is immediately increased to monthly for the remaining permit term (until December 31, 2014) Noncompliance with Analytical Test Results It is the responsibility of the Site Manager to review all laboratory reports from all analytical sampling. The NPDES permit details Benchmark Values or Effluent Limitations for the various test parameters. if any of these limits are exceeded, there are additional monitoring requirements that are described in the permit. Mine Dewatering Wastewater Effluent Limitations for Mine Dewatering Wastewater Settleable Solids 0.1 ml/I Total Suspended Solids (TSS) N/A pH 6.0 - 9.0 Turbidity N/A (See below) The discharge shall not cause the turbidity of the receiving water to exceed Water Quality Standards (50 NTU). If turbidity of the receiving stream exceeds these levels due to natural background conditions, the existing turbidity level shall not be increased. According to the NPDES Permit, "an exceedence of any of these limitations is a violation of the permit conditions and may be subject to enforcement action". If the sampling results are above a limitation for any parameter, then the monitoring schedule shall be immediately increased to monthly for the remaining permit term (until December 31, 2014) Reporting non -compliant analytical results: In addition to the increased monitoring schedule descried above, the Site Manager is responsible for notifying the NCDENR Division of Water Quality of any benchmark value exceedences or effluent limit violations. Mine Dewatering: One signed DMR form with wastewater effluent limitations violations shall be sent to the NCDENR DWQ Wilmington Regional Office no later than 30 days from the date that the Environmental Manager receives the sampling results from the laboratory. Copies of all DMR forms shall be kept in the SWPPP notebook onsite. Reporting other violations: It is the responsibility of the Field Inspectors to report any spills or non- compliance issues to the Site Manager. If the non-compliance issue could endanger health, safety, or the environment, or if the spill is considered "significant", then it is the responsibility of the Environmental Manager to contact the NCDENR DWQ of the situation within 24 hours. 4. Spill Prevention and Response Plan The following information is presented as a Spill Prevention and Response Plan (SPRP) prepared in accordance with the requirements of the NPDES Permit Stormwater Pollution Prevention Plan. The goal of this plan is to prevent spills, leaks, or other releases of potential pollutants at the facility that could result in a discharge of these pollutants via stormwater. Assessment of Potential Pollutants Potential pollutants at this site are the various fuels, oils, lubricants, and fluids associated with the equipment operation and maintenance onsite. None of these materials are stored in bulk onsite. The quantities of materials that may be contained within any given piece of equipment is too small to cause a spill that would potentially leave the site. Facility Personnel Responsible for Implementing the SPRP Facility Response Coordinator & team members: Team Member Name & Title Day Phone # Night Phone # Acknowledgement of individual responsibilities "I have read the "Duties and Responsibilities of facility response coordinator and team members" found in Section 5.5.7 of the SPCC Plan and acknowledge my responsibility for this plan". Date 5. Preventative Maintenance and Good Housekeeping Program Preventative maintenance is essential for the proper operation of all equipment. Such maintenance will significantly reduce the potential for leaks and spills of fuels, lubricants, fluids, and coolants, and therefore, greatly reduce potential pollution of surface water or groundwater. Garner Construction Company has a Preventative Maintenance Schedule for each piece of equipment onsite. The schedule should be followed to assure that the potential for leaks or spills is kept at a minimum. In addition, each piece of equipment is thoroughly inspected before each use. If a suspected or obvious leak or potential spill is recognized, the piece of equipment should be immediately shut down and measures should be taken to repair or isolate the problem. No equipment should be used or operated if a known potential leak or spill could occur. Fuels, lubricants, coolants, hydraulic fluids, and other petroleum products shall not be discharged on the ground or into surface waters. Spent lubricants and fuels shall be removed from site as needed. If any spill or leak occurs, action should be taken immediately to contain and clean up the spill. Schedules and records of equipment maintenance are kept by the Site Manager and are available for inspection at any time. Any spills that require clean up are recorded in Part 1 of this SWPPP. 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. At a minimum, all oil -handling personnel are given annual training in oil spill prevention, including operation and maintenance of equipment. Where specific responsibilities are assigned, these requirements will be reviewed. All such training occasions will be documented with an employee roster that is signed by each employee.. A copy of the plan will be on display, accessible to all employees at all times. New employees will be given as much spill prevention training as is commensurate with his new status and ability to be effective. This training is typically provided within one week of his employment. Documentation and records of all training related to the SWPPP are filed in Appendix 7. 7. Responsible Party According to the NPDES Permit, Part IV, Section 5, all applications, reports, or information submitted to the Director shall be signed and certified by a Corporate Officer or a "duly authorized representative". The Stormwater Pollution Prevention Plan is written and reviewed under the direction of the Site Manager. He should review the requirements of the NPDES permit and assure that they are being met. He should assure that the Sediment and Erosion Control Plan associated with the NC Mining Permit meets the requirements of the BMP Plan. He is responsible for submitting any required modifications of the Sediment and Erosion Control Plan with the Mining Permit to keep the site in compliance with the NPDES permit. He should respond to any questions, concerns, or notifications of maintenance or repair issues with any of the BMPs at this site. He should regularly review inspection reports of the BMPs and implement any necessary repairs or maintenance. He should regularly review the BMP plan and any records or logs to assure compliance. He should review the Discharge Monitoring Reports, and if any samples are out of compliance, take immediate measures to correct the issue and bring the site into compliance. He is also responsible for the required inspections of BMP's as specified in the permit. All stormwater BMPs shall be inspected by the Site Manager or his designee at least once every 7 days and within 24 hours after any storm event that results in a discharge. He should follow the guidelines as described in the "Weekly BMP Inspections of Sediment and Erosion Control Structures". The Site Manager is responsible for maintenance and repair of the BMP structures. If any visible sedimentation is seen leaving the site, corrective action shall be taken to reduce or eliminate the discharge of sediments. The Site Manager is responsible for keeping a log of inspections of BMPs as well as a log of any maintenance or repairs to BMPs. He should also maintain a file containing NPDES sampling records and test results. The Site Manager is also responsible for preventive maintenance of equipment as well as good housekeeping practices to prevent potential discharge of pollutants. 8. Plan Amendment This Stormwater Pollution Prevention Plan shall be amended whenever there is a change in design, construction, operation, or maintenance that has a significant effect on the potential for the discharge of pollutants to surface waters. All aspects of the SWPPP shall be reviewed and updated on an annual basis. The annual update shall include an updated list of significant spills or leaks of pollutants for the previous three (3) years, or the notation that no spills have occurred. The annual update shall include written re -certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges (part le). Each annual update shall include a documented re-evaluation of the effectiveness of the BMP's listed in the BMP Summary of the Stormwater Management Plan. The following Annual Review and Update Checklist serves as a guide and certification for the required review. Annual Review and Update Checklist It is the responsibility of the Site Manager to review and update the Stormwater Pollution Prevention Plan (SWPPP) on an annual basis (as per NPDES Permit Part III, Section A-8). It is important that ALL aspects of the SWPPP be reviewed and updated where necessary. This checklist should serve as a guide to assist in this process. While the annual review should be as comprehensive as possible, the SWPPP should be amended whenever there is a change in design, construction, operation, or maintenance that has a significant effect on the potential for the discharge of pollutants to surface waters. Site Inspection: The Annual Review and Update should include a thorough inspection of the site. A current copy of the Site Plan should be used for reference in the inspection. Each BMP 1 Sediment and Erosion Control feature should be inspected. Does the Site Plan accurately reflect the actual site configuration? Is each BMP 1 Sediment and Erosion Control feature functioning as designed? Are they being properly maintained? Are there any points that stormwater is leaving the site due to failure of any sediment and erosion control structure? Are there any other stormwater outfalls not indicated on the Site Plan? Is there any evidence of sediment or other pollutants leaving the site or potentially impacting a surface water? Are there any new sources of potential pollutants not shown on the Site Plan? Is there a functioning rain gauge onsite? Is there evidence of the presence of any non-stormwater discharges at any outfall? Site Plan: Has there been any modification of the State Mining Permit? If so, any changes should be indicated on the SWPPP Site Plan. Are all monitoring locations and BMP's clearly marked on the map? Is the existing Sediment and Erosion Control Plan associated with the State Mining Permit adequate for preventing pollution associated with Stormwater from leaving the site or entering surface waters? Records and reports: Have all Mine Dewatering Discharges been monitored quarterly as required? Have all test results been within the required limits? If not, have the proper steps been taken for additional monitoring? The following records and reports should be filed in the SWPPP notebook: All DMR's filed within the last 5 years. All Mine Dewatering monitoring reports (including lab reports) for the last 5 years. Also includes analysis for semi-annual TPH monitoring. Rainfall.data from onsite rain gauge. Weekly BMP Inspections, properly documented by the Site Manager. Employee Training Are all oil -handling personnel given annual training in spill prevention and proper operation of equipment? Is there written documentation of the employee training? Overall Evaluation After the SWPPP has been reviewed and modified as necessary, the following statement should be signed by the Site Manager: "I have reviewed the Stormwater Pollution Prevention Plan and all associated evaluations, monitoring results, reports, and data.

The N01 shall be submitted and a certificate of coverage issued prior to any discharge of stormwater associated with industrial activity, mine dewatering wastewater, or process wastewater that has a point source discharge to the surface waters of the state. This General Permit covers mining and quarrying of nonmetallic minerals (except fuels) including borrow pits (that would not be covered under the statewide DOT stormwater permit) and active or inactive mines that discharge stormwater contaminated with, or that has come in contact with, any overburden, raw material, intermediate products, finished products, byproducts or waste products located at the site of such operations and stormwater runoff from vehicle maintenance areas. This General Permit also covers discharge of wastewater from processing mined materials and mine dewatering wastewater from the groundwater and/or stormwater that accumulates in the mine pit. Any owner or operator not wishing to be covered or limited by this General Permit may make application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H .0100, stating the reasons supporting the request. Any application for an individual permit should be made at least 180 days prior to commencement of discharge. This General Permit does not cover activities or discharges covered by an individual NPDES permit until the individual permit has expired or has been revoked. Any person conducting an activity covered by an individual permit but which could be covered by this General Permit may request that the individual permit be revoked and coverage under this General Permit be provided. Any facility may apply for new or continued coverage under this permit until a Total Maximum Daily Load (TMDL) for pollutants for stormwater or wastewater discharges is established. A TMDL sets a pollutant -loading limit that affects a watershed, or portion of a watershed, draining to an impaired water. For discharges to watersheds affected by a TMDL, coverage under this permit may depend on the facility demonstrating it does not have reasonable potential to violate applicable water quality standards for those pollutants as a result of discharges. If the Division determines that discharges have reasonable potential to cause water quality standard violations, the facility shall apply for an individual permit 180 days prior to the expiration date of this general permit. Once that individual permit is effective, the facility will no longer have coverage under this general permit. [Note the permittee must identify impaired waters (scheduled for TMDL development) and waters already subject to a TMDL in the Site Plan, as outlined in the Stormwater Pollution Prevention Plan (SPPP), Part III, Section A. Parts I -II Page 1 of 4 Permit No. NCGO20000 SECTION B: PERMITTED ACTIVITIES Until this permit expires or is modified or revoked, the permittee is authorized to discharge stormwater, mine dewatering, and/or process wastewater to the surface waters of North Carolina or a separate storm sewer system which has been adequately treated and managed in accordance with the terms and conditions of this General Permit. Types of approved discharges are dependent upon approval and are detailed in the permittee's individual Certificate of Coverage (COC). All discharges shall be in accordance with the conditions of this permit. Any other point source discharge to surface waters of the state is prohibited unless it is an allowable non-stormwater discharge or is covered by another permit, authorization, or approval. If mining activities will expand or change such that the types of discharges are affected, the permittee is to contact DWQ to determine if modifications to the COC are necessary first. The permittee is also responsible for contacting the Division of Land Resources (DLR) if modifications to the Mining Permit are necessary, as compliance with the Mining Permit is a stipulation of this permit. The discharges allowed by this General Permit shall not cause or contribute to violations of Water Quality Standards. Discharges allowed by this permit must meet applicable wetland standards as outlined in 15A NCAC 2B .0230 and .0231 and water quality certification requirements as outlined in 15A NCAC 2H .0500. This permit does not relieve the permittee's responsibility for compliance with any other applicable federal, state or local law, rule, standard, ordinance, order or decree. PART lI - AUTHORIZATION TO CONSTRUCT AND OPERATE A TREATMENT FACILITY Mining operations involving construction and operation of wastewater treatment facilities for mine dewatering or process wastewater (such as saw water, wash water, etc.) are subject to construction and operation requirements for treatment facilities as outlined in Sections A and B below. SECTION A: REQUIREMENTS FOR CONSTRUCTING NEW OR EXPANDING WASTEWATER TREATMENT FACILITIES 1. All new or expanding wastewater treatment facilities must receive an Authorization to Construct (AtC) from DWQ, unless specifically excluded in Part II1, Section E in this permit. Treatment facility arrangements excluded from the AtC requirement are as follows: ♦ Dewatering wastewater directly pumped from the pit through erosion and sedimentation control facilities and that does not require additional treatment other than those structures to meet effluent limits prior to discharge. ♦ Water conveyed from mined sand and/or gravel through erosion and sedimentation control facilities and that does not require additional treatment other than those structures to meet effluent limits prior to discharge., ♦ Closed -loop process recycle wastewater systems that are designed to operate with a minimum of two feet (2') of freeboard and that limit the water entering the system to makeup water and/or precipitation that falls directly into the system (i.e., exclude stormwater runoff from draining into the system). ♦ Facilities designed to administer polyacrylamides (DAMS) or other chemical flocculant materials, as long as administered in accordance with Division requirements and that do not require additional treatment other than those structures to meet effluent limits prior to discharge. Parts I-11 Page 2 of 4 Permit No. NCG020000 Treatment facility arrangements that are subject to AtC requirement include, but are not limited to: ♦ Dewatering wastewater treatment facilities for discharges that do not meet effluent limits and do not protect water quality standards. ♦ Process recycle wastewater systems that are not designed to operate with a minimum of two feet (2') of freeboard and/or do not otherwise meet criteria to be considered closed -loop recycle system (i.e., Non -closed -loop recycle systems). 2. Application for the AtC requires that plans and specifications be submitted to the Division of Water Quality, Stormwater Permitting Unit, 1617 Mail Service Center, Raleigh, NC 27699- 1617 for approval. 3. Upon approval of the plans and specifications by the Division, a set of approved plans and specifications for the subject project will be returned to the permittee. These plans must be retained by the permittee for the life of the treatment facility. 4. Upon receipt of an approved AtC, approved treatment facilities shall be constructed and implemented in accordance with the conditions of this permit, approved plans and specifications, and other supporting data. Treatment facilities shall be constructed to meet the effluent limitations in Part III, Section E of this General Permit. All such inspections must be documented with printed name, date, and signature of individual performing the inspection(s). 5. Upon completion of construction and prior to operation of a permitted facility, a certification of plans and specifications must be received from a professional engineer in accordance with G.S. 89-25 certifying that the permitted facility has been installed in accordance with this permit, the approved plans and specifications, and other supporting materials. Mail the Certification of plans and specifications to the Division of Water Quality, Stormwater Permitting Unit, 1617 Mail Service Center, Raleigh, NC 27699-1617. 6. The permittee shall notify the DWQ Regional Office at least seventy-two (72) hours in advance of operation of the installed facilities so that an in -place inspection can be made if the Regional Office so desires. Such notification to the Regional Supervisor shall be made during normal business hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays. Parts I-11 Page 3 of 4 Permit No. NCG020000 SECTION B: REQUIREMENTS FOR OPERATION OF A WASTEWATER TREATMENT FACILITY Existing, new and expanding wastewater treatment facilities shall be subject to the following operational requirements. Operation and maintenance of treatment facilities must be in accordance with the requirements in this General Permit. For the purposes of this permit no documentation other than a signed Certificate of Coverage is required to operate an existing treatment facility. New treatment facilities must also have an Authorization to Construct (AtC) permit, with the exceptions noted in Section A above. 2. Diversion or bypass of untreated wastewater from a treatment facility is prohibited except under provisions of this permit in Part IV, Section C.3 and Part IV, Section E.7 3. In the event that a facility fails to perform satisfactorily, including the creation of nuisance conditions, the permittee shall take immediate corrective action, including those actions that may be required by this Division, such as the construction of additional or replacement treatment or disposal facilities. 4. The issuance of this permit shall not relieve the permittee of the responsibility for damages to surface waters of the State resulting from the operation of a treatment facility. 5. Any discharge from a treatment system to groundwater must protect the groundwater standards specified in 15A NCAC 2L, Groundwater Classification and Standards. 6. Any groundwater quality monitoring, as deemed reasonably necessary by the Division, shall be provided. 7. Flocculants evaluated by the Division may be used if administered in accordance with maximum application doses and any other current requirements. No other chemical flocculants shall be used in the treatment facility without written authorization from the Division. Evaluated Polyacrylamide (PAMS) information can be found via the Stormwater Permitting Unit website. All discharges of mine dewatering wastewater and process wastewater will be monitored in accordance with Part III, Section E of this permit. Parts I -II Page 4 of 4 Permit No. NCG020000 PART III — MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED DISCHARGES SECTION A: STORMWATER POLLUTION AND PREVENTION PLAN (SPPP) All permittees shall develop and implement a Stormwater Pollution Prevention Plan (SPPP), herein after referred to as the Plan. This Plan shall be considered public information in accordance with Part IV, Standard Conditions, Section E, Paragraph 3 of this General Permit. The Plan shall include, at a minimum, the following items: 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. (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. (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 must also be identified on the site map: fueling, engine maintenance and repair, vessel maintenance and repair, washing, painting, sanding, blasting, welding, and metal fabrication. (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. (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 S. The permittee shall re -certify annually that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. Part III Page 1 of 16 Pages Permit No. NCG020000 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. 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 Stormwater 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). (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. Reduced Inspections far 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, and/or 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. 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 Part III Page 2 of 16 Pages Permit No. NCG020000 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. oil/water separators) shall be inspected and qualitatively monitored (as per Part III. 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. (c) Secondary Containment Requirements and Records. Secondary containment is required for: bulk storage of liquid materials; storage in any amount of Section 313 of Title III 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. 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. 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, Part III Page 3 of 16 Pages Permit No. NCG020000 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. 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. 7. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific position(s) responsible for the overall coordination, development, implementation, and revision to the Plan. Responsibilities for all components of the Plan shall be documented and position assignments provided. 8. Plan Amendment. The permittee shall amend the Plan whenever there is a change in design, construction, operation, or maintenance that has a significant effect on the potential for the discharge of pollutants to surface waters. All aspects of the Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual basis. The annual update shall include an updated list of significant spills or leaks of pollutants for the previous three (3) years, or the notation that no spills have occurred. The annual update shall include written re -certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. Each annual update shall include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management Plan. The Director may notify the permittee when the Plan does not meet one or more of the minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit a time schedule to the Director for modifying the Plan to meet minimum requirements. The permittee shall provide certification in writing (in accordance with Part VI, Standard Conditions, Section B, Paragraph 5) to the Director that the changes have been made. 9. Plan Implementation. The permittee shall implement the Plan and all appropriate BMPs to ensure that contaminants do not enter surface waters via stormwater that comes in contact with any unstabilized overburden, raw materials, intermediate products, finished products, byproducts or waste products located on the site covered by this permit. Implementation of the Plan shall include documentation of all monitoring, measurements, inspections, maintenance activities, and training provided to employees, including the log of the sampling data and of actions taken to implement BMPs associated with the industrial activities, including vehicle maintenance activities. Such documentation shall be kept on - site for a period of five years and made available to the Director or the Director's authorized representative immediately upon request. SECTION B: STORMWATER DISCHARGES: ANALYTICAL MONITORING REQUIREMENTS Stormwater discharges are defined as stormwater from mining activity areas, including (but not limited to) areas of mine excavation, other land disturbance, process areas, and vehicle maintenance. This section does not apply to wastewater discharges from mine dewatering Part III Page 4 of 16 Pages Permit No. NC6020000 and process areas. Analytical monitoring for stormwater discharges shall be performed for parameters as specified in Tables 1 through 3. All analytical monitoring shall be performed during a representative storm event as defined below. Monitoring Exemption Analytical monitoring is not required for any basin or pond designed to contain the 25-year, 24- hour storm (see Part VII, Definitions) without discharging, and that can regain capacity to hold such an event within five (5) days' time through means other than discharge to surface waters. A basin or pond that meets this provision is considered a non -discharging stormwater control. Table 1. Analytical Monitoring Requirements for Stormwater Discharges from Mining Activities Discharge.

Measurement Frequency: Twice per year during a representative storm event, as defined for this permit. Failure to comply with semi-annual monitoring in accordance with permit terms for any six-month monitoring, period immediately_ triggers monthly monitoring for the remaining permit term. 2. Grab samples shall be collected within the first 30 minutes of discharge. For sites where multiple outfalls are separated by distances that preclude collection within 30 minutes of each discharge event is not feasible, begin collection procedures within 30 minutes and continue until all outfalls with discharges are sampled. Documentation explaining why it was not possible to take samples within the first 30 minutes must be kept in the SPPP. 3. Sample Location: Samples shall he collected at each stormwater discharge outfall (SDO) unless representative outfall status (ROS) has been granted and documented by the Division of Water Quality. A copy of the letter granting ROS shall be kept on site. 4. Turbidity may be monitored at the Stormwater Discharge Outfall. Alternatively, the permittee may choose to monitor turbidity in the receiving water, directly upstream and downstream of the stormwater discharge outfall(s). 5. For each sampled representative storm event the total precipitation must be recorded. An on -site rain gauge or local rain gauge reading must be recorded. 6. Total flow shall be: (a) measured continuously, or (b) calculated based on the amount of area draining to the outfall, the amount of impervious area, and the total amount of rainfall, or (c) estimated by the measurement of flow at 20 minute intervals during the rainfall event. Total rainfall precipitation and duration of the rainfall event refers to the representative storm event sampled. All analytical monitoring shall be performed during a representative storm event at each stormwater discharge outfall [SDO). The permit allows the permittee to monitor turbidity at the SDO or up- and downstream of the SDO; however, the permittee should consider regular turbidity sampling up- and downstream of the discharge(s) when feasible to ensure compliance with water quality standards. Part 111 Page 5 of 16 Pages Permit No. NCGO20000 A representative storm event for the purposes of this General Permit is a storm event that measures greater than 0.1 inches of rainfall. The time between this storm event and the previous storm event measuring greater than 0.1 inches must be at least 48 hours. One storm event may have a time period within it that has no precipitation. This time period may last up to 10 hours. For example, if it rains but stops before producing any collectable discharge, a sample may be collected if the next rain producing a discharge begins within 10 hours. The permittee shall complete the analytical samplings in accordance with the schedule specified in Table 2. A minimum of 60 days must separate each sample event unless monthly monitoring has been instituted under a Tier 2 response. Failure to comply with semi-annual monitoring in accordance with permit terms for any six-month monitoring period immediately triggers month) monitoring for the remaining permit term, unless adverse weather conditions prevent sample collection during the sample collection period. Inability to sample due to adverse weather conditions must be documented in the SPPP with date, time and written narrative (see Adverse Weather in Definitions) and reported on the Annual Summary DMR. Table 2. Monitoring Schedule Semi-annual MonitoringlEvents� z Start Date, .(AII Year9 End Date (All Years) 3 1 January 1 June 30 2 July 1 December 31 Footnotes: 1. Maintain semi-annual monitoring during permit renewal process (unless tiers prompt monthly). If at the expiration of the General Permit, the permittee has submitted an application for renewal of coverage before the submittal deadline, the permittee will be considered for renewed coverage. The applicant must continue monitoring until the renewed Certificate of Coverage is issued. 2. If no discharge occurs during the sampling period, the permittee must record "No Flow" or "No Discharge" within 30 days of the end of the six-month sampling period in the SPPP. "No Flow" or "No Discharge" shall be reported on the Annual Summary Discharge Monitoring Reports (DMR). This DMR is to be submitted to the Division's Central Office by March 1 of each year. 3. Monitoring periods remain constant throughout the five-year permit term (from January 1, 2010 to December 31, 2014). In all cases, the permittee shall report (as required in Part IV, Section E.) the analytical results from each sample within the monitoring period. The permittee shall compare those results to the benchmark values in Table 3. Exceedences of benchmark values require the permittee to increase monitoring, increase management actions, increase record keeping, send the monthly monitoring results to the appropriate Regional Office, and/or install stormwater Best Management Practices (BMPs) in a tiered program. See below the descriptions of tiered response actions. Table 3. Benchmark Values for Stormwater Discharges Discharge Characteristics Benchmark Values Settleable Solids 0.1 ml 1 Total Suspended Solids (TSS) 100 mg/1 TSS ORW, Ii W, trout, and PNA waters 50 mg/1 Turbidity N/A See below Part III Page 6 of 16 Pages Permit No. NCG020000 The discharge shall not cause the turbidity of the receiving water to exceed Water Quality Standards: ' 10 NTU freshwater streams, lakes, and reservoirs designated as trout waters 25 NTU all lakes and reservoirs, and all salt waters 50 NTU all other streams and surface waters If turbidity of the receiving stream exceeds these levels due to natural background conditions, the existing turbidity level shall not be increased. If the turbidity exceeds these levels as a result of stormwater discharges, the permittee must immediately institute Tier 2 response actions, including monthly monitoring of all stormwater discharge outfalls to the receiving waters. The permit allows the permittee to monitor turbidity in the effluent or up- and downstream of the discharge point; however, the permittee should consider regular turbidity sampling up- and downstream of the discharge(s) when feasible to ensure compliance with water quality standards. Tier One If: The first valid sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at any outfall; Then: The permittee shall 1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling results. 2. Identify and evaluate possible causes of the benchmark value exceedence. 3. Identify potential and select the specific: source controls, operational controls, or physical improvements to reduce concentrations of the parameters of concern, or to bring concentrations within the benchmark range. 4. Implement the selected actions within two months of the inspection. S. Record each instance of a Tier One response in the Stormwater Pollution Prevention Plan. Include the date and value of the benchmark exceedence, the inspection date, the personnel conducting the inspection, the selected actions, and the date the selected actions were implemented. 6. Send all monitoring results for that sample period to the appropriate DWQ Regional Office. Part III Page 7 of 16 Pages Permit No. NCG020000 Tier Two If: During the term of this permit, the first valid sampling results from two (2) consecutive monitoring periods are above the benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall; Then: The permittee shall 1. Repeat all the required actions outlined above in Tier One. 2. Immediately institute monthly monitoring for all parameters at every outfall where a sampling result exceeded the benchmark value for two (2) consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three (3) consecutive samples are below the benchmark values or within the benchmark range. 3. Send all monthly monitoring to the appropriate DWQ Regional Office. 4. If no discharge occurs during the sampling period, the permittee is required to record "No Flow" or "No Discharge" in the SPPP for the sampling the period to comply with monthly monitoring requirements and must submit reports in accordance with this permit. 5. Maintain a record of Tier Two responses in the Stormwater Pollution Prevention Plan. 'Tier'Three During the term of this permit, if the valid sampling results required for the permit monitoring periods exceed the benchmark value, or are outside the benchmark range, for any specific parameter at any specific outfall on four (4) occasions, the permittee shall notify the DWQ Regional Office Supervisor in writing within 30 days of receipt of the fourth analytical results. DWQ may but is not limited to: • Require that the permittee revise, increase, or decrease the monitoring frequency for the remainder of the permit; • Rescind coverage under the General Permit, and require that the permittee to apply for an individual stormwater discharge permit; • Require the permittee to implement in -stream Turbidity Monitoring (U,D) • Require the permittee to install or modify structural stormwater controls; or • Require the permittee to implement other stormwater control measures SECTION C: ON -SITE VEHICLE MAINTENANCE MONITORING REQUIREMENTS (STORMWATER DISCHARGES) Facilities which 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 as specified below in Table 4. This monitoring shall be performed at all outfalls discharging stormwater runoff from vehicle maintenance areas, and in accordance with the Part III Page 8 of 16 Pages Permit No. NCG020000 schedule presented in below.

A copy of any letter granting ROS shall be kept on site. 2. For any outfalls represented by SDOs with representative status for qualitative monitoring, qualitative monitoring is only required annually instead of semi-annually. Representative outfall status (ROS) specifically for qualitative monitoring may be granted for some stormwater.outfalls and must be documented by the Division of Water Quality. Qualitative monitoring for all outfalls represented must still be performed annually at a minimum. Qualitative monitoring records shall not be turned into the Division except when requested. Qualitative monitoring records shall be maintained on site as part of the SPPP. Part III Page 10 of 16 Pages Permit No. NCG020000 Qualitative monitoring is for the purposes of evaluating the effectiveness of the Stormwater Pollution Prevention Plan (SPPP), assessing new sources of stormwater pollution, and prompting the permittee's response actions to pollution. If the permittee repeatedly fails to respond effectively to correct problems identified by qualitative monitoring, or if the discharge causes or contributes to a water quality standard violation, DWQ may but is not limited to: • Require that the permittee revise, increase, or decrease the monitoring frequency for the remainder of the permit; • Rescind coverage under the General Permit, and require that the permittee to apply for an individual stormwater discharge permit; • Require the permittee to implement in -stream Turbidity Monitoring (U,D) • Require the permittee to install or modify structural stormwater controls; or • Require the permittee to implement other stormwater control measures SECTION E: WASTEWATER DISCHARGES: EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS FOR MINE DEWATERING WASTEWATER & PROCESS WASTEWATER 1. MINE DEWATERING WASTEWATER Mine dewatering requirements apply to all mines that dewater from pits including quarries, clay brick, sand & gravel, borrow pits, and refractory mining, as well as mines with similar discharges. Note that for Construction Sand and Gravel or Industrial Sand mines, "mine dewatering' wastewater includes wet pit overflows caused solely by direct rainfall and groundwater seepage. During the period beginning on the effective date of the permit and lasting until expiration, the permittee is authorized to discharge mine dewatering wastewater controlled in accordance with the conditions of this permit. Mine dewatering activities that have the potential to drain wetlands or other surface waters must have secured and implemented a Pumping Operation and Monitoring (O&M) Plan approved by the Division. Pumping 0&M Plans shall include, but are not limited to: • Groundwater monitoring strategies to demonstrate the effect of pumping. • Detailed plans to maintain the surrounding hydrology that protects the affected streams and wetlands and the respective monitoring to demonstrate compliance. • The pumping regime deemed necessary to protect affected streams and wetlands. Alternative site specific pumping and monitoring regimes may be approved by the Division on a case -by -case basis. At the Division's discretion, approval of the Pumping 0&M Plan may be required prior to coverage under this general permit. Analytical monitoring of mine dewatering wastewater shall be performed as specified below in Table 7. For each parameter, an effluent limitation is contained in Table 8. An exceedence of any of these limitations is a violation of the permit conditions and may be subject to enforcement action as specified in Part IV, Section A.2 of this permit. Part III Page 11 of 16 Pages Permit No. NCG020000 Mine Dewatering Treatment System ATC Requirement: Engineered erosion and sedimentation control (E&SC) structures that sufficiently treat mine dewatering wastewater so that permit effluent limits are met and water quality is protected, do not require an Authorization to Construct (AtC) and may operate in accordance with Part 11, Sections A and B. Any additional treatment devices (other than erosion and sediment control structures) needed to meet permit limits and conditions are subject to Authorization to Construct (AtC) requirements. 2. PROCESS WASTEWATER Process wastewater includes, but may not be limited to, the water involved in the slurry transport, washing, sawing of mined material, air emissions control or processing exclusive of mining of sand, gravel and stone washing operations, dimension stone cutting operations, and air scrubbing and dust control operations. A) Overflow From Non -Closed Loop Recycle Systems A "closed -loop" system is a wastewater recycle system where the only other water that may be added is either make-up water or precipitation that falls directly into the system. "Closed -loop" systems must operate at or below two feet of freeboard and must be designed to exclude stormwater runoff from draining into it. Non -closed -loop recycle systems may recycle water, but do not meet the above design criteria. During the period beginning on the effective date of the permit and lasting until expiration, the permittee is authorized to discharge overflow from the process recycle wastewater systems that are not designed as closed -loop recycle systems. Analytical monitoring of overflow from process recycle wastewater systems that are not designed as closed -loop recycle systems shall be performed as specified below in Table 7. For each parameter, an effluent limitation is contained in Table 8. For the purposes of this permit, overflow refers to a discharge of process wastewater as a result of a precipitation event. Non -Closed -Loop Recycle System ATC Requirement: Non -closed loop recycle systems do not meet the requirements for closed -loop recycle systems and are not designed and operated with two feet of freeboard. Authorization to construct and operate requirements (Part Il, Sections A and B) are applicable to non -closed -loop recycle systems. B) Other Treated Process Wastewater Discharges During the period beginning on the effective date of the permit and lasting until expiration, the permittee is authorized to discharge treated process wastewater from mining operations. Treatment may involve conveyance through erosion and sedimentation control (E&SC) structures and/or other engineered treatment systems. Analytical monitoring of process wastewater shall be performed as specified below in Table 7. For each parameter, an effluent limitation is contained in Table 8. An exceedence of any of these limitations will result in a violation of the permit conditions and may be subject to enforcement action as specified in Part IV, Section A.2 of this permit. Part III Page 12 of 16 Pages Permit No. NCG020000 Process Wastewater Treatment System ATC Requirement: Engineered Erosion and Sedimentation control (E&SC) structures that sufficiently treat process wastewater so that permit effluent limits are met and water quality is protected, do not require an authorization to construct (AtC) and may operate in accordance with Part II, Sections A and B.

No limit in the effluent discharge applies, but turbidity in the receiving waters shall not exceed levels described below as a result of wastewater discharges. 4. The total volume of treated wastewater for all discharges combined shall not exceed 50 percent of the total in -stream flow of the receiving waters under 7Q10 conditions in HQW waters, including trout and PNA waters. The discharge shall not cause the turbidity of the receiving water to exceed Water Quality Standards: 10 NTU freshwater streams, lakes, and reservoirs designated as trout waters 25 NTU all lakes and reservoirs, and all salt waters 50 NTU all other streams and surface waters If turbidity of the receiving stream exceeds these levels due to natural background conditions, the existing turbidity level shall not be increased. If the turbidity exceeds these levels as a result of wastewater discharges, the permittee must immediately institute monthly monitoring for all parameters. The permit allows the permittee to monitor turbidity in the effluent or up- and downstream of the discharge point; however, the permittee should consider regular turbidity sampling up- and downstream of the discharge(s) when feasible to ensure compliance with water quality standards. The permittee shall complete the analytical samplings of wastewater discharges in accordance with the schedule specified in Table 9. Failure to comply with quarterly monitoring in accordance with permit terms for any one calendar quarter immediately triggers monthly monitoring for all parameters for the remaining permit term.

Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities, retention of stormwater or maintenance during normal periods of equipment downtime or dry weather. This condition is not satisfied if adequate backup controls should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and C. The permittee submitted notices as required under Section E of this Part. If the Director determines that it will meet the three conditions listed above, the Director may approve an anticipated bypass after considering its adverse effects.
