INTRODUCTION North Carolina Permit No. NCS000101 requires this Stormwater Pollution Prevention Plan to be an active document during the coverage of the permit. The International Paper Company site which is covered by this Plan is located in Riegelwood, NC, at 865 John L. Riegel Road off HWY 87, south of the Cape Fear River and adjacent to Livingston Creek. International Paper discharges treated effluent from its wastewater treatment facility into the Cape Fear River under NPDES Permit No. NC0003298. A USGS quadrangle map showing the location of the facility in relation to transportation routes and surface waters is located in Appendix E. The majority of the stormwater which comes into contact with industrial processes is routed to the wastewater treatment system. A network of treatment ponds and effluent discharge structures limit the influence of stormwater on the performance of the WWTS. Discharges are regulated by the NPDES permit and are monitored continuously. Stormwater routed to this system is not discussed in this plan. The limited areas of industrial activity exposed to rainwater discharging to either the Cape Fear River or Livingston Creek are the subject of this plan and are covered by the permit. Page 14 IV. STORMWATER POLLUTION PREVENTION TEAM A separate Spill Prevention and Response Plan (SPRP) is not needed in the SWPPP because there is no uncontained chemical storage in stormwater basins. There is a separate SPRP section in the mill Spill Prevention Control and Countermeasures (SPCC) Plan that addresses oil spill response. In addition, there are numerous other manuals and plans in place that describe the activities governing environmental management systems at the facility in general and in stormwater basins in particular. Spill prevention and response are collectively addressed by the: 1) the Operations Manual for Waterfront Dock Transfers, 2) the Operations Manual for Oil Spill Response Plan, 3) the Chemical Hygiene Plan, 4) the Spill Prevention Control and Countermeasures (SPCC) Plan, 5) the Best Management Practices Plan for Spent Pulping Liquor, Soap, and Turpentine Management, Spill Prevention, and Control, 6) the Environmental Manual, and 7) the Stormwater Pollution Prevention Plan. These plans specify procedures and instructions for achieving regulatory compliance. This Stormwater Plan specifies individuals who would best be capable of addressing problems and concerns in the stormwater basins. The pulpmill foreman is the responsible party after hours and on weekends The MILL MANAGER is responsible for providing resources for the working team and designating responsible individuals as specified in this Plan. Page 15 The ENVIRONMENTAL PERFORMANCE MANAGER is responsible for coordinating improvements to facilities to allow for compliance with this plan and the Stormwater Permit. He is also responsible for relaying the proper methods used for stormwater management to the Mill Engineers. The Environmental Performance Manager will be a member of the Audit/Inspection Team. The MAINTENANCE MANAGER is responsible for providing manpower support for correction to facilities, for providing the necessary information to maintenance personnel in stormwater housekeeping techniques, and for requiring compliance with erosion and sediment control standards by all contractors working with maintenance. The Maintenance Manager will be a member of the Audit/Inspection Team. The ENVIRONMENTAL COORDINATOR is responsible for implementing and maintaining this Plan, for maintaining contact with NC-DEM, for remaining up- to-date with any regulation changes related to stormwater discharges, for smaintaining the documentation associated with stormwater control facilities, for spill reporting, and for coordinating sampling. The Environmental Coordinator will be a member of the Audit/Inspection Team and will coordinate the periodic inspections. Page 16 The SAFETY DIRECTOR is responsible for maintaining equipment for emergency spill response, for conducting the emergency response, for providing Spill Response Training for the Emergency Response Team, and is responsible for contractors working at the milt_ TABLE IV.1.

IDENTIFICATION OF STORM WATER DISCHARGE POINTS. The site is divided into 19 specific storm water drainage areas associated with industrial activities. These drainage points are limited to those not treated through the WWTS. No pesticides, soil conditioners, or fertilizers are stored or used in the stormwater basins at the mill. No off -site drainages combine with stormwater runoff from these basins. No waste disposal activity takes place within the stormwater drainage areas. There are no dust control processes in stormwater basins. A USGS General Location Map and a Stormwater Basins Map are located in Appendix F. When additional discharge channels are found during stormwater inspections or at other times, these potential discharge locations are corrected. Any additional discharge points that develop are considered monitoring points and are sampled for qualitative observation if the flow is strong enough. 1) Basin A Basin A is located north northeast of the mill at 34" 21' 25" N and 78'0 12' 38" W. It covers about 4.24 acres of land that is all impervious. Oil barge unloading is the only mill activity in Basin A. The area includes the oil unloading pipeline and a mill access road. Runoff passes through drainage channels under the fenceline, then is diffused by gravel and riprap as it sheets to the Cape Fear River. Page 18 2) Basin B Basin B is located north northeast of the mill at 340 21' 19" N and 781 12' 32" W. It covers about 0.57 acres of land that is 60% impervious. Stormwater is directed via a grassy swale, drainage pipes, and three culverts through a collection basin, then on through the woods to the Cape Fear River. The area consists of a firewater house, No. 5 cooling tower, chemical storage and feed equipment for corrosion inhibitor in cooling water, electrical control room C-94, and a mill access road. Chemicals are stored in non -corrosive tanks within secondary containment. The containment drains to the mill WWTS. Much of the area is riprapped and graveled. 3) Basin C Basin C is located north of the mill at 340 21' 27" N and 780 12' 46" W. It covers about 1.58 acres of land, of which 40% is impervious. Stormwater is directed via a concrete culvert and a drainage pipe to an unnamed tributary of the Cape Fear River. Industrial activities in this area are limited to transfer and storage of raw wood chips, a wood chip truck dumper, and a mill access road. Secondary containment around the truck dump hydraulic reservoir and the hydraulic truck lift in Basin C ensures that any losses from the truck lift or reservoir pump are prevented from flowing off -site. 4) Basin D Basin D is located north of the mill, next to Basins C & E at 340 21' 27" N and 7811 12' 43" W. It covers about 0.37 acres of land that is approximately 24% impervious. Stormwater is directed via a concrete culvert, a pipe and drainage Page 19 channels to an unnamed tributary of the Cape Fear River. Industrial activity in this area is limited to transfer and storage of raw wood chips, a firewater house, and a mill access road. 5) Basin E Basin E is located north of the mill, next to Basins C & D at 340 21' 25" N and 780 12' 48" W. It covers about 4.04 acres of land, of which 25% is impervious. Stormwater is directed via pipe and drainage channels to the unnamed tributary of Cape Fear River. Industrial activities in this area are limited to transfer and storage of raw wood chips, a wood chip truck dumper, chip screening, and a mill access road. Secondary containment surrounds the truck dump hydraulic reservoir and the hydraulic truck lift. Runoff from the truck lift and mill road passes through an oil/water separator (OWS) before discharge. 6) Basin F Basin F is located north of the mill, next to Basin E at 340 21' 25"N and 780 12' 48"W, 34 21' 26" N and 78 12' 50" W, and 34 21' 26" N and 78 12' 51"W, It covers about 0.48 acres of land and is approximately 46% impervious. Industrial activities in this area are limited to a mill access road, an electrical control room, and water storage. Runoff down the intake road flows along a rocky channel with stone deflectors and is directed to the discharge point by a paved diverter across the road. Runoff from the roadway around the potable water tank is directed through an underground gravel French drain to a pipe Page 20 through the fence. Remaining runoff sheets across the ground and exits the fenceline through a pipe. All runoff is directed via drainage channels to an unnamed tributary of the Cape Fear River. 7) Basin G Basin G is located north northwest of the mill at 340 21' 25" N and 781 12, 53" W. It covers about 1.12 acres of land, of which approximately 20% is impervious. Basin G stormwater is directed via pipes and drainage channels to an unnamed tributary of the Cape Fear River. The west fenceline has 3 outfalls that drain over gravel and through pipes. Industrial activities in this area are limited to transfer of raw wood chips, maintenance material storage, mill access roads, and rail lines. The water treatment plant is adjacent to Basin G. Runoff from the mill road and rail area collects in a small collection basin, then runs through an oil/water separator and exits the mill through a concrete pipe. Secondary containment surrounds the truck dump hydraulic reservoir, the hydraulic truck lift, and the railcar hydraulic reservoir. These three containments drain via u-drain into the mill 1NWTS. 8) Basin H Basin H is located west of the mill at 341 21' 25" N and 781 12' 53" W. It covers about 0.78 acres of land that is graveled and impervious. Stormwater is directed via drainage channels and a riprapped pipe to an unnamed tributary Page 21 of the Cape Fear River. Industrial activities in this area include rail lines for incoming raw wood chips and a mill access road. 9) Basin I Basin I is located south of the mill, next to Basin L at 341 20' 55" N and 780 12, 54" W. The area covers about 1.67 acres of land that is paved and is impervious. Stormwater in one section flows into a concrete catch basin and pipe, and the remainder sheets across the surface and through a slotted concrete diffusion baffle. Runoff from both areas combines to run across a grassy area to a second catch basin, then exits through a steel pipe to a collection pond. This pond drains via a concrete pipe under the road, then travels along to an unnamed tributary of Livingston Creek, and eventually to the Cape Fear River. Industrial activities in this area are limited to parking for trailers and trucks transporting finished products, and a rail line for some mill process areas. 10) Basin J Basin J is located southwest of the mill at 340 21' 03" N and 780 12' 56" W. It covers about 1.77 acres of land, all of which is graveled and impervious. Stormwater is directed, on the west side by a retaining berm and on the east by a collection pond, through channels and drainpipes to an underground pipe that resurfaces and allows flow to meander through a wooded area. From there stormwater passes through concrete pipes and two collection ponds to Page 22 an unnamed tributary of Livingston Creek, and from there, eventually to the Cape Fear River. Industrial activities in this area are limited to a truck weighing station, rail lines for incoming wood chips and logs, railcar repair, and mill access roads. 11) Basin K Basin K is located south of the mill, next to Basin P at 341 20' 40" N and 781 13' 05" W_ It covers about 1.40 acres of land, and all is impervious. Stormwater is directed via a riprapped Swale and a pipe to a small collection area. Overflow passes through a pipe under the passtracks to an unnamed tributary of Livingston Creek and eventually to the Cape Fear River. The area consists of an access road for utilities and the rail passtracks. 12) Basin L Basin L is located south of the mill, next to Basin I at 340 20' 54" N and 780 12' 48" W. The area covers approximately 2 acres of land, which is covered with geotextile and graveled, and is impervious. Stormwater is directed via a catch basin and concrete culvert to a collection pond, which overflows south via a pipe under the road to an unnamed tributary of Livingston Creek and eventually to the Cape Fear River. Industrial activity in this area is limited to parking for trailers transporting finished products. 13) Basin M Page 23 Basin M is located east northeast of the mill at 340 21' 11" N and 780 12' 27" W. It covers about 1.36 acres of land that is all impervious. Basin M includes mill roads, a firehouse, and a contained methanol storage tank. The Basin M outfall flows into the Ravine, through a meandering stream, and on to the Cape Fear River. Outfall 2 runoff is now ditched to the WTS. 14) Basin N Basin N is located north northeast of the mill, next to Basins B & O at 340 21, 21" N and 780 12' 33" W. It covers about 0.15 acres of land and is all graveled and impervious. Basin N includes access to the north end of No. 3 cooling tower and chemical storage and feed equipment for cooling tower biocides. Cooling water process chemicals are stored in non -corrosive containers in secondary containment that drains to the WWTS. Basin N runoff drains via a concrete drainage channel and a pipe and runs through the woods to the Cape Fear River. 1S) Basin O Basin O is located north northeast of the mill, next to Basins B & N at 341) 20, 26" N and 780 12' 33" W. It covers about 0.10 acres of land, all of which is graveled and impervious. Industrial activities in this area are limited to access to the south end of No. 3 cooling tower and chemical storage and feed equipment for biocides and corrosion inhibitor. Cooling water process chemicals are stored in non -corrosive containers in secondary containment that Page 24 drains to the WWTS. Basin O runoff drains via a concrete drainage channel and a pipe, and runs through the woods to the Cape Fear River. 16) Basin P is located south of the mill, next to Basin K at 341 21' 46" N and 780 12' 02" W. It covers about 3.20 acres of land that is graveled and impervious. Industrial activities in this area are limited to construction equipment storage, truck and trailer parking, and office trailers. Stormwater directed via a catch basin, pipes, and riprapped drainage, channel. Channelized runoff and pond overflow pass under the passtracks via a pipe to an unnamed tributary of Livingston Creek and eventually to the Cape Fear River. 17) Basin Q Basin Q is located north of the mill, past Basin E at 340 21' 29" N and 780 12' 42" W. It covers about 0.72 acres of land on the Cape Fear River and is approximately 50% impervious. The mill water intake and mill road are in Basin Q. Stormwater is directed through two discharge pipes and channels through the woods to the Cape Fear River. 18) Basin R Basin R is located south of the mill, west of the mill road next to Basin S, at 34 20' 46" N and 78 13' 22" W. It covers 13.57 acres of land and is impervious. Stormwater sheets over gravel from the NE corner and follows meandering streams through two- sections of woods and a grassy swale before joining an Page 25 unnamed tributary of Livingston Creek, and eventually, the Cape Fear River. Industrial activity in this area is limited to parking for trailers transporting finished products. 19) Basin S Basin S is located south of Basin R on •the mill road, in the west one-third of the contractor parking lot at 34 20' 62" N and 78 13' 35" W. Basin S covers approximately 1.95 acres and is impervious. Stormwater sheets over gravel to the south fenceline and is channeled through a rock filter into a sedimentation basin outside the fence. Water from the NW corner of the basin drains into a grassy channel that adjoins the sedimentation basin. Overflow from the pond flows through the woods via a meandering stream, then is directed east via concrete pipes under several roads, then on to an unnamed tributary of Livingston Creek and eventually to the Cape Fear River. Industrial activity in this area is limited to staging for trailers transporting logs, and wood chips. 20) Basin 1 was temporarily named as a mill stormwater basin. A separate Stormwater permit application now designates this basin as an enclosed system operating independently from the mill NPDES permit. Page 26 The truck parking area, or "staging area", located between Basins I and P is excluded from "industrial activity", as specified in the mill's stormwater discharge permit. This area is located on plant lands separated from the plant's industrial activities and is considered a parking area for trucks. The drainage is not mixed with storm water drained from the above described areas; consequently, the term excludes this area from coverage under the permit. Page 27 VI.

Evaluation led to the subsequent relocation of biocide stored in Basins N and O. The biocide is now located in secondary containment which drains to the wastewater treatment system. The evaluation also led to installation of a french drain in Basin A, the relocation of the day oil tanks at the diesel tank, and the installation of a cement pad, drain and sump at the diesel tank in the woodyard. Recent evaluations led to a decision to place an oil water separator and sump within Basins F and G. A containment was built around a second oil storage area by the gasoline garage. A u-drain with an in -line oil/water separator now catches runoff from both the heavy equipment garage and the gasoline garage and diverts it to the WWTS. Consequently the garage area, including liquid cleaner storage, has been removed from stormwater basin J. Also, in the later part of 1999 oil water separators were installed prior to the outfall pipes at Basin G and Basin E. These separators were installed as preventative measures to ensure oil and grease within the basins do not discharge through the storm water outfalls. The separators are preceded by collection sumps and screens to direct flow to the OWS inlet and to remove debris (bark, fiber, dirt) collected in these basins. POLLUTION PREVENTION MEASURES (2001 -2004) Page 30 Stormwater area evaluations led to installation in 2004 of secondary containments around hydraulic chip dumps in areas C, E, and G. A U-drain to the WWTS now catches runoff from the rail and the truck chip dumps in area G, 1 removing them from stormwater area G. The areas of Basin J from the woodyard office west and north to the cooling tower at #6 evaporators, and south to the the diesel fuel tank area have been captured with ditching and piping to the WWTS, removing those areas from stormwater basins. Also in 2004, the black liquor pond adjacent to area H was permanently removed from service. POLLUTION PREVENTION MEASURES (2005-2007) Persistent drainage issues arose after the installation of perimeter fencing in 2005. Erosion issues under the new fenceline in Basins F and G were addressed by installing small flex hoses under the fenceline in strategic locations to control flow and erosion. Per instructions from NCDENR, these pipes are identified by signage and sampled as outfalls G-1-14 and F-1-3. Additionally, the new fenceline at Basin C was relocated to allow sampling at the outfall culvert. New stormwater signage was erected millwide for employee and contractor education in 2005. Signs mark boundaries of basins as well as outfalls. In 2006, diversions were constructed in Basin F to correct stormwater flow to the designated outfall. Also, a beaver dam was removed from the outlet pipe to Livingston Creek, restoring proper drainage from Basins J, I, and L. Page 31 POLLUTION PREVENTION MEASURES (2008-2010) Basin M Outfall 2 runoff is now ditched to the WTS. The drainpipe for the Basin M outfall 2 was permanently plugged and the ditch on the north side of the road was filled to minimize flow of stormwater toward the river. In addition, the ditch on the south side of the road was improved, and the roadbed was raised and regraded to facilitate drainage to the pond adjacent to the North Basin. Runoff from the new mill landfill cell also flows into this ditch and on to the WWTS. The collection pond at Basin B was cleaned out to remove accumulated sediment and the north bank of the pond was seeded to discourage erosion. Basins N and O were regraded and regraveled to keep flow directed to permitted outfalls. Between Basins K and P, the riprapped area along the Swale was extended and a drainpipe was installed under the roadbed. Grading was corrected near Basin A, and rock was installed to stabilize the surface. In Basin F a gravel French drain was installed from the roadway at the potable water tank to the fenceline to channel flow and control erosion. Also, material storage was removed from Basin F as a mill activity. Page 32 VII. TRAINING PROGRAM Training will be coordinated by the Riegelwood Operations Human Resources Department. Training will be conducted annually via computer -based training (CBT). Employees in the following departments/areas must complete the training annually: EHS, Maintenance, Power, Recovery, PSD, Technical, Filter Plant, Woodyard. Employee Training Maintenance and production supervisors and foremen are on hand around the clock and are instructed on the elements of this plan. Instruction addresses topics such as spill response, good housekeeping and materials management practices. The employee training syllabus is found on page 23. In addition to the annual CBT training, signage is posted marking the boundaries of stormwater basins and describing activities prohibited in the basins. Additional signs indicate the exact locations of stormwater outfalls. All new mill employees and contractors receive environmental management system training related to chemical release prevention and emergency procedures. Best Management Practices from the Environmental Manual that are included in the training include the following environmental procedures: o Ep5.2-2a, Emergency Chemical Release and Spill Management, a Ep5.2-2b, Non -emergency Chemical Release and Spill Management, o Ep5.2-2f, Report for Chemical Release or Spill, and Page 33 o EP5.2-3d, Cleanup procedures for Small Oil Spills and Proper Handling of Oily Materials. Contractor Training Contractors will be instructed in our requirements for pollution prevention through careful chemical handling and quick clean-up response. They will be instructed as to which operations may or may not be accomplished in potential stormwater contact areas described in Section V. New contractors will receive this training as part of their contractor orientation prior to entry on the mill site. For established contractors, refresher instruction will be conducted periodically with the award of new contracts. Every contractor with earth moving potential or chemical operations potential will be covered with this training. EMPLOYEE TRAINING SYLLABUS STORM WATER POLLUTION PREVENTION Training includes: a) International Paper Company's legal and ethical requirement to maintain a Stormwater Permit for discharges outside of its wastewater treatment boundaries. a) Section V of the Stormwater Plan, Identification of Stormwater Discharge Points. Page 34 b) Activities banned from storm water outfall areas. Any variances must be approved by Environmental staff, and appropriate precautions must be in place in writing before the change is implemented. Any exceptions must be accompanied by strict, appropriate, written operating procedures. Typical modification requirements are noted in parentheses. - Painting - Vehicle maintenance involving lube/hydraulic fluids, - Vehicle parking/storage. The only exception is the fenced -off contractor office area in Basin P. Vehicles stored there carry spill containment materials at all times. - Vehicle washing, except for water rinsing. - Outdoor chemical storage, unless adequate containment is provided as in Basins B, N, and O - Outdoor hazardous waste collection. - Fuel stations unless the following standards are met: a. Paved area which could capture drips and small spills. b. Double containment of storage tanks. c. Covered double containment of fueling areas. c) Good housekeeping measures must be practiced. Equipment shall be properly maintained and materials shall be correctly stored to eliminate a possible contribution to storm water discharges. Page 35 d) Chemicals and other materials which can contribute to stormwater pollutants shall be stored in double -contained and covered environments. These include but are not limited to: paint, oils, greases, degreasers, and fuels. e) All personnel shall respond to spills in an expeditious manner to prevent the spread to storm water outfall areas. Notify Security (Extension 6222) about any significant event. Generally, a significant event is considered a spill of more than one gallon in a stormwater controlled area. f) For earth moving activities, the Area Supervisor or Engineer shall be responsible for assuring sediment and erosion control measures are in place. g) Any chemical to be used must be approved by the mill Environmental and Safety staff using the "New Chemical Acceptance" forms and procedures. Page 36 VE9. STORM WATER MANAGEMENT PLAN 1) Feasibility Study for Exposure Reduction A review of the technical and economic feasibility of changing the methods of operations and /or storage practices to eliminate or reduce exposure of materials and processes to stormwater is required. Industrial activities are limited in stormwater areas and are removed from runoff areas whenever it is feasible to do so. Precautions taken to minimize exposure are listed in this section of the Plan, and are also detailed in the basin descriptions in Section V of the Plan, and in the BMP descriptions in #3 of this section. Actions accomplished to eliminate or reduce exposure to stormwater follow this section. Basins B, N, O: The mills main two cooling towers are located in Basins B, N, and O. The mill is too congested to relocate these large structures away from the mill perimeter; additionally, it is not economically feasible to change the infrastructure that supports this operation. However, containment is provided for the cooling towers and associated water treatment chemicals, and sump pumps capture rainfall and any spillage and send it to the WWTS for treatment. Basins C, D, E, G, H, J : In all these basins the main activity is transport, unloading, transfer, and storage of wood chips. Due to the magnitude of chip Page 37 handling and its extensive infrastructure it is not feasible to relocate this activity or to completely eliminate exposure. The truck and rail dumpers and pump motors in Basins C, E, and G contain large amounts of hydraulic oil, but this exposure risk is contained and none of these containments discharge to stormwater. Water treatment chemicals have been removed from Basin F, minimizing potential pollutants. Basin G incorporates maintenance material and equipment storage that presents very little exposure risk and has not been relocated due to space and logistical constraints. The inactive black liquor pipeline has been removed from Basins G and H, eliminating the potential for exposure. Rail lines in Basins H and J deliver chips, and railcars containing chemicals and byproducts pass through Basin J and I. Rail lines must pass through stormwater areas to reach production areas; however, materials contained in railcars are considered a low risk of stormwater contamination. Basins A, I, L, R, S, K, P, M, and Q: Basin A includes the mill's riverfront dock. The most efficient way to transport fuel oil to the mill is by barge, and it is not economically feasible to remove this activity from the waterfront. Spill containment equipment is stored at the dock. In Basins I, L, R, and S, exposure risk is very low, being limited to stored trailers: some empty, some containing finished product, and some containing logs or chips. Space and economic constraints prevent complete removal of exposure. In Basin P, a laydown yard, material and equipment storage also poses a very low risk, with most industrial pollutants banned from the area. Basins K and M are mill roads. Basin K offers Page 38 access to utilities and the railroad passtracks that pose little risk. The mill does not own and cannot relocate this infrastructure that is critical to operations. In Basin M the primary potential pollutant is the methanol tank. Methanol is located outside the mill chemical area due to safety and space constraints, but is adjacent to that area for operational reasons. Basin Q is the mill water intake, which must be on the waterfront. This location is permitted and cannot be relocated. The only possible pollutant is backwash from the water treatment plant, which is captured in a pond and pumped back into the mill water supply. The following is a review of precautions taken to prevent material exposure to stormwater: -Basin A has been re -added to the SWPPP. The basin was previously removed from the plan when drainage was routed to the WWTS. However, recent evaluation shows that part of the basin continues to drain to the Cape Fear River. _-Fueling stations have been removed from the basins. -Outdoor hazardous waste collection has been prohibited. -Chemical storage, at Basins B, N, and O has been moved and now has secondary containment leading to the wastewater treatment system. -Secondary containment has been added around hydraulic units in Basins C and F. Page 39 -Material storage has been removed from Basin F. -Secondary containment and drainage to the WWTS have been added at hydraulic units in Basin G. -Drainage has been improved in Basin M to accommodate newly created runoff from landfill construction roads. -The black liquor pond adjacent to Basin H was taken out of service. -Runoff from the woodyard cooling tower and coalpile have been rerouted to the WWTS, removing those areas from Basin J. -In new construction Basin 1(one), the future wet yard, an enclosed runoff recycling system has been constructed to keep this area separate from the SWPPP. A separate permit now covers the wet yard. -The unused black liquor line was removed from Basins G and H. - Basin I was repaved. -Basin L was regarded and partially paved. -In Basins, C and D, the roadways were repaved, reducing erosion potential. -A rock filter was added in both Basins C and R. -Chemical storage for water treatment was relocated outside Basin F. z) Secondary Containment Sumps and containment structures that do not drain directly to the WWTS are pumped out as needed to the WWTS. Page 40 3) Best Management Practices (BMP's) Sedimentation basins are used at some locations to trap and prevent sediment from being discharged from the site. Basins are inspected no less than two (2) times. per year and cleaned as needed. All BMPs are shown on the mill stormwater map. Page 41 APPENDIX A - DISCUSSION OF SIGNIFICANT ENVIRONMENTAL EVENTS In 2007, a potable water reservoir was cleaned and during the process, a pipe broke, spilling sludge from the tank bottom onto the ground. An estimated 100 gallons flowed off site toward the unnamed tributary of the Cape Fear River. At the request of the NCDENR Department of Water Quality, creek water was tested before the confluence with the river, and water quality was found to be uncompromised. In 2008, a potable water line running from the mill to the golf course next door failed, releasing an estimated 500 gallons of potable water to the unnamed tributary of the Cape Fear River. There was no observable impact on the creek. On July 17, 2008 a 2" potable water line cracked, releasing an estimated 17,000 gallons to an unnamed tributary of the Cape Fear River. On .July 19, 2008 a 5" potable water line failed, releasing a maximum of 5000 gallons of potable water to the same unnamed tributary. Both leaks were valved off immediately upon discovery and repaired within a few days. There was no observable impact to the creek#rom either event.

Page 46 APPENDIX D - MONITORING AND SAMPLING PLAN Analytical Monitoring 1 1) Stormwater sampling will be conducted semi-annually each year of the permit term, once in the spring (April -June), and once in the fall (September — November). The Monitoring Report form is in Appendix E, and the actual reports are stored in the Environmental Central Files under the August 1, 2007 NPDES Stormwater permit, Analytical sampling sites are Outfall B, Outfall E, and Outfall I. These sites are considered equivalent to other basin outfalls and provide adequate representation of the mill's overall storm water quality. Equivalent basin history may be found in the Environmental Central Files; current equivalent basins are footnoted in the permit. 2) Rainfall meeting the following specifications may be sampled: -Within specified Spring and Fall months, when possible. .-Greater than 0.1 inches of rainfall. -Is preceded by at least 72 hours in which no storm event of greater than 0.1 inches has occurred. 3) Samples for each outfall to be retrieved are: - Grab samples, defined as individual samples collected instantaneously. All samples, including samples taken from sedimentation basins, must be collected within the first 30 minutes of discharge. Record the times of Page 47 day that samples are collected on the Stormwater Discharge Calculations Worksheet below. Total flow for each sampled representative storm event will be calculated based on the amount of area draining to the outfall and the total amount of rainfall measured. 4) Samples will be analyzed for the following parameters: COMPOSITEMNITS BOD5 (mg/1) COD (mg/1) TSS (mg/1) pH Total Rainfall (inches) Event Duration (minutes) Total Flow (MG) Visual Monitoring 1) Visual monitoring requires semiannual qualitative inspections at outfalls A through S for the following characteristics.

Containeryard Sediment Control Project Lotic Solutions 2. Basin E, T COD — Tier 3 Resolution 3. Inspect ground cover for closure of New Woodyard S&E permit quality improvement. A major rebuild of bank fortifications in Basin 13 is in progress to restore storntwater quality in Basin B. An intensive investigation revealed the source of the ongoing problem, which was a damaged pipe buried from view under heavy riprap. Unfortunately, the first - choice contractor for this project was unable to meet mill safety requirements. This caused some delay while an alternate qualified vendor was hired. Repairs are ongoing, with positive results even before completion. Monthly sampling will continue until runoff quality is within benchmarks for three consecutive months. Basin E Basin E was in Tier 2 in the Fall. 2017 semester; with month]), sampling. Basin E results for BOD, TSS, and pl-I remained within benchmarks. Intensive housekeeping efforts appear to be controlling COD in Basin l=, and the most recent six samples have been within the benchmark of 120 mg/L. `I -he conforming Fall 2017 results are 94, 101, 48, and 50 mg/L. This recent performance exceeds the permit requirement of three consecutive samples within benchmarks, allowing. relief front the monthly Tier 2 sampling obligation. International Paper requests that \CDEQ DEI.MLR allow the facilty to return to semi-annual Tier 1 monitoring`t Basi I-. beginning in the Spring. 2018 semester. Basin I Basin I remains in Tier 1, Basin I BOD and pH were within benchmarks, but COD was above the benchmark of 120 mg/L at 190 mg/L. TSS results were also above the 100 mg/L benchmark with a result of 146mQ/i_. No visible cause was evident for the exceedances: however, in 2016, COD and TSS were similarly high, and an underground pipe section was found to have separated. Pipe repairs were made; with subsequent results within benchmarks. Because of similarities in the exceedances it is suspected that a different section of the pipe may have failed. An inspection of the entire pipeline is planned in an effort to investigate and correct these occurrences. It is our understanding that once a benchmark exceedance is corrected and acceptable runoff quality is proven, as in the 2016 exceedance. that issue is considered completed and closed; and is no longer included when totaling any future exceedances for Tier 2 and Tier 3 qualification. Consequently, the current benchmark exceedances at Basin I, are considered the firstTier1 exceedances for COI) and TSS for Basin I. .:.1 c�w••it3 '�� fie. e/•....., � c a} Basin T Basin T remains in Tier 1. Basin T results for the first valid sample of the semester show BOD. TSS, and p1l within benchmarks. The COD sample was above the benchmark of 120 mg/L, with a value of 188mg/L. Wood debris has been shown to cause high COD, and housekeeping in Basin T remains intensive. N7easures will be reviewed with area departments to ensure that the maximum effort continues in this area to remove woody material.

Lab results are included; as well as a mill stormwater basin reap. Analytical samples were collected on 7/29/2017, 8/5/2017, 9/5/2017, 10/19/2017, and 12/20/2017 for Basins B, E,1, and T. Analytical samples were collected for representative Basins B, E, and 1, and for Basin T. Basin T was added to the mill SWPPP in 2015 due to construction of a new scalehouse for wood trucks_ thus there is no representative status for Basin T. As with previous new basins, full analytical sampling will be continued until quality data is established, then representative status may be requested. Most recent analytical results were received from the contract lab Envirochem on January 8, 2018, and appear in the attached data table. Tier 1 valid samples are collected once a semester. Tier 2 or 3 sampling is required monthly; however, weather conditions sometimes do not allow safe, representative sampling, and more often than not, rain falls in the evenings after work hours. Tier 2I3 monthly sampling will continue as safety and rainfall timing allow_ A rainfall log in the environmental lab documents representative rain events. Analytical Results and Corrective Actions For the Fall 2017 sampling event, most lab results were within permit benchmarks, with good runoff quality. Detailed information for each basin is outlined below. Basin B Basin B COD, BOD, and pH results continue to conform with permit benchmarks. Basin B was under Tier 2 monthly sampling after high TSS results the previous two semesters; monthly sampling began in September 2017, at the first sampling opportunity. In previous months the outfall did not discharge. Despite some repairs, two monthly TSS results (September and October, 2017) were 178 and 590 mg/L, respectively, versus the benchmark of 100. These results may move 13asin B into Tier 3, with a total of 4 occasions of TSS above the benchmark during the current permit term; however, the most recent sample in December 2017 was within the benchmark at 98 mg/E, showing runoff S/Groups/EnvironmentaVStormwater/Reports/2017/FalI 2017/AnaVCvr Ur I certify, under penalty of laxv. that this document and all attachments -were prepared under my direction or supervision in accordance With a system designed to assure that qualified personnel properly gather and evaluate the information submitted.
