The facility is located on the south side of Old US 421. The receiving waters for the stormwater discharge is an unnamed tributary to Indian Branch. Indian Branch is a WS-IV stream in the Cape Fear River Basin (Figure 1, Attachment A). Other pertinent information for the facility includes: Address: 1085 Old US 421, Lillington, NC 27330 Phone: 919-775-7951 Latitude: 350 23' 38.7528" N Longitude: 78150' 34.5156" W The facility has one building that contains metal processing equipment and an office area. The Standard Industry Classification (SIC) Code for the facility is 5093 (Scrap Metal Recycling). Limited scrap metal equipment and vehicle refueling activities are conducted at the site. Several above ground storage tanks (ASTs) are located at the facility. All vehicle maintenance is conducted inside the building The facility accepts scrap metal and processes the material for recycling purposes. Commonly accepted materials include copper, steel, aluminum, scrap cars, and other raw metal materials. No hazardous or toxic materials of any kind are accepted at the facility. The scrap metal materials including vehicles are stockpiled in the gravel/grass areas outside of the building. The majority of the materials processing occurs within the building. Vehicles to be processed have fluids drained inside the building. The fluids are drained directly into barrels or other temporary storage containers. The liquids are then transferred to the above ground tanks located outside of the building. End of life vehicles are also processed by a crusher that is located outside of the building. No significant spills or leaks have occurred at the site during the previous three (3) years. 11,aCertificatian far N6n`Starmwmater DlScli'Nar ,._ . _.. The Lee Iron & Metal requires a permit to discharge storm water because materials are potentially in contact with storm water. As a requirement of this permit, the outfalls associated with storm water discharges from areas of industrial activity have been evaluated for the presence of non -storm water discharges. Based on the evaluation, to the best of my knowledge and belief, no non -storm water discharges exist.

Page 2 2.0 STORMWATERIMANAGEMENT�S,T�R.ATEG�Y, '�µ,fi The Lee Iron & Metal facility has one (1) discharge point (See Storm Water Plan, Sheet 1). Discharges are stormwater runoff from the building and storage areas. Stormwater runoff is conveyed by an existing grassed ditch and the discharge occurs at a natural low point on the western boundary of the property. Possible pollutants that could discharge include soil particulate, metals, and petroleum (gasoline, diesel, used motor oil, and hydraulic oil). The Facility Stormwater Plan (Sheet 1) shows the discharge point, watershed area, and the potential pollutants that could occur from these activities. Outfall No. 1 The watershed for Outfall No. 1 is approximately 10.57 acres and includes approximately 5.31 acres of impervious area. The entire site including the building, stockpiled materials, and ASTs drain to this outfall. 2.1 ASTsand Secor<dary,Containmenta �I; A Spill Prevention Control and Counter Measure Plan (SPCC) has been prepared and implemented for the storage of petroleum products and other fluids. This plan is contained under separate cover. At the Lee Iron & Metal Facility, five (5) Above Ground Storage Tanks (AST's) are in -use that are outside of the plant buildings. The Storm Water Plan, Sheet No. 1, shows the locations of these tanks. These AST's include the following: • One (1) 200 gallon off -road diesel transfer tank • One (1) 1,000 gallon off -road diesel tank • One (1) 1,000 gallon gasoline tank • One (1) 1,000 gallon used oil tank • One (1) 1,000 gallon water and antifreeze tank The 200 gallon off -road diesel tank is on wheels and is used to fill the crusher. This tank is usually empty unless it is being used to transfer fuel to the crusher. All of the other tanks are double -walled for secondary containment purposes. The majority of scrap metal processing occurs inside of the building. Vehicles to be processed have fluids drained inside the building. The fluids are drained into barrels or other temporary storage containers. All chemicals are stored inside of the plant buildings. e2.s Storrawater Pollution Prevention Plan (SPPP) Lee Iron & Metal Co. Page 3 Some scour and rill erosion is occurring on the gravel surfaced parking/storage area. Stormwater runoff with erosive velocities from the upslope areas is the likely cause of the scouring. In order to decrease the runoff velocity and reduce the potential for additional scouring, water bars are proposed. The water bars should consist of a 9" high compacted earthen ridge with cross slopes of less than I %. The relatively flat cross slopes will help to attenuate the stormwater runoff to non -erosive. The proposed water bars should discharge into the existing ditch located in the central portion of the property. Please note that these proposed measures are tentative and subject to change. In order to implement, maintain and revise the SPPP; Lee Iron & Metal Co. has assigned the following personnel to be members of the Pollution Prevention Team. The activities and responsibilities of each team member are listed below. A responsible person shall be on -site at all times during facility operations that have increased potential to contaminate stormwater runoff through spills or exposure of materials associated with the facility operation.

The ultimate solution of pollution runoff is storage of materials and conducting activities under roof to prevent direct contact with precipitation. 61S Stormwater Pollution Prevention Plan (SPPP) Lee Iron & Metal Co. Page 4 The majority of scrap metal processing occurs inside of the building. Vehicles to be processed have fluids drained inside the building. The fluids are drained into barrels or other temporary storage containers. All chemicals are stored inside of the plant buildings. Spills and leaks are a significant potential source of stormwater pollutants, and in many cases, are avoidable. The standard operating procedures such as spill prevention procedures, along with proper employee training can reduce the potential for accidental releases. The following areas are identified for potential spillage: -Above ground gasoline and diesel tanks. -Waste oil collection, hydraulic oil collection, radiator fluid collection and other fluids used and handled at the building. -Petroleum releases from hydraulic equipment, construction equipment, vehicles and stationary motor operated equipment. -Car crusher For the above ground gasoline and diesel tanks, the operation procedures are outlined separately in the Spill Prevention Control and Countermeasures Plan. Storage of fluids at the plant buildings is in areas out of congested pedestrian and vehicle traffic. Should a spill occur, the material is immediately cleaned up using absorbent pads and powder. Should the release saturate the ground, the soil is removed and placed in appropriate containers (barrels, roll -offs, etc.). At various locations of the plant, a release could result from any of the hydraulic equipment, stationary motors and from moving trucks and construction equipment. The release is immediately adsorbed, and ground contaminated is excavated and the soil is removed and placed in barrels. All releases are immediately reported to the Stormwater Plan Coordinator or any of the other Pollution Prevention Team Members, G? 3 Stormwater Pollution Prevention Plan (SPPP) Lee Iron & Metal Co. Page 5 TATIVE' MAINTENANCE A _ , 4 4.0 PREVEN _ � ND GO"Q—VSEKEEPING`" , The following areas require Good Housekeeping Activities to minimize stormwater releases: 1) Plant Building Cleaning 2) Draining of vehicle fluids 3) Raw material handling Following is a discussion of the good housekeeping activities for the above items 1. Handling of the containers is conducted in a manner to minimize spillage. Spills are immediately cleaned up. 2. Building floor cleaning is conducted by using absorbent powder, dry wiping and sweeping. The used material is appropriately disposed off -site. No washing with water is allowed, unless the water is vacuumed at the same time. The following items are inspected routinely for future maintenance activities: 1. Vehicles 2. Scrap metal moving equipment 3. Hydraulic lines 4. Crushing equipment Following is a discussion of the preventative maintenance activities for the above items. 1. At the designated parking areas for the various transport vehicles, the ground should be checked for any ground staining or liquid ponding before each day's use. Staining or ponding is evidence of needed vehicle maintenance. 2. Material handling equipment should be checked for hydraulic line leaks and other leaks that require maintenance. 3. Hydraulic lines should be checked by the operator before each day's use for leakage. Any spill should be cleaned immediately, and repairs made when leakage is noted. 4. Self contained petroleum tanks, hydraulic lines, and the area around the equipment should be checked for leak and/or spills. Any spill should be cleaned immediately, and repairs made when leakage is noted. 5. Metal crushing equipment should be periodically inspected for signs of leaks and ground staining. Labels should be placed on all containers containing flammable, hazardous, or corrosive materials. The labels should indicate the type of material contained. Signs indicating proper handling and cleanup procedures should be posted where these materials are stored. Standards for hazardous material labeling are per OSHAIMSHA standards. 61 Stormwater Pollution Prevention Plan (SPPP) Lee Iron & Metal Co. _ _ Page 6 5 U'FACILITYaINSPECTIS ON Inspection of the facility shall occur at a minimum of twice a year; once during the first half of the year (January to June) and once during the second half (July to December), with at least 60 days separating inspection dates. The Bi-Annual observation by qualified personnel is conducted to perform the following: • Inspect storm water drainage areas for evidence of pollutants entering the site drainage system. • Evaluate the effectiveness of measures to reduce pollutant loadings and whether additional measures are needed. • Inspect any equipment needed to implement the plan, such as spill response equipment. • Revise the plan as needed within two weeks of inspection (potential pollutant source description of measures and controls). • Implement any necessary changes in a timely manner, but at least within 12 weeks of the inspection. • Prepare a report summarizing inspection and follow up actions, the date of inspection and personnel who conducted the inspection; identify any incidents of noncompliance or certify that the facility is in compliance with the plan. • Sign the report and keep it with the plan.

This plan is prepared for the Lee Iron & Metal facility in Lillington, NC (See Figure No. 1 of Attachment A for location). The 24" by 36" Facility Stormwater Plan (I 12.7(a)(3)) drawing shows the subject site and facility. The Lee Iron & Metal facility is located in Lillington, Harnett County, NC. The facility is located on the south side of Old US 421. Other pertinent information for the facility includes: Address: 1085 Old US 421, Lillington, NC 27330 Phone: 919-775-7951 Latitude: 350 23' 38.7528" N Longitude: 78° 50' 34.5156" W The facility has one building that contains metal processing equipment and an office area. The Standard Industry Classification (SIC) Code for the facility is 5093 (Scrap Metal Recycling). Limited scrap metal moving equipment and vehicle refueling activities are conducted at the site. Five (5) above ground storage tanks (ASTs) are located at the facility. These ASTs are described in further detail in Section I.I. The facility accepts scrap metal and processes the material for recycling purposes. Commonly accepted materials include copper, steel, aluminum, scrap cars, and other raw metal materials. No hazardous or toxic materials of any kind are accepted at the facility. The scrap metal materials including vehicles are stockpiled in the gravel/grass areas outside of the building. The majority of the materials processing occurs within the building. Vehicles to be processed have fluids drained inside the building. The fluids are drained directly into barrels or other temporary storage containers. The liquids are then transferred to the above ground tanks located outside of the building. End of life vehicles are also processed by a crusher that is located outside of the building. C?S Spill Prevention Control and Counter Measure Plan (SPCC) Lee Iron & Metal Co. Page 2 1:3 �,IAS'I'.and�Secottcla ,�Coritainment �4„ ,; At the Lee Iron & Metal Facility, five (5) -Above Ground Storage Tanks (AST's) are in -use that are outside of the plant buildings. The Storm Water Plan, Sheet No. 1, shows the locations of these tanks. These AST's include the following: • One (1) 200 gallon off -road diesel transfer tank • One (1) 1,000 gallon off -road diesel tank • One (1) 1,000 gallon usedgasoline tank • One (1) 1,000 gallon used oil tank • One (1) 1,000 gallon water and antifreeze tank The 1,000 gallon off -road diesel tank is used to refill the on -site equipment. The other tanks are used to store used gasoline, oil, and antifreeze, respectively, that is drained from vehicles that are brought to the facility to be scrapped. The 200 gallon off -road diesel tank is on wheels and is used to fill the crusher. This tank is usually empty unless it is being used to transfer fuel to the crusher. All of the other tanks are double -walled for secondary containment purposes. The 1,000 gallon off -road diesel tank A the only AST at the facility that is filled by delivery tank truck unloading, and is the only tank used to dispensed product. An on -site representative should monitor anytime that the 1,000 gallon off -road diesel is being filled by a delivery tank truck, and ensure that the tank is not overfilled. In general, any release would be absorbed by the grassed areas before leaving the property. However, a timely response will minimize potential cleanup costs, such as plugging the culvert and/or providing absorbent pads and booms along the ditch. '-1 3Wq!Pasi-ReleaseDo men aNn' No past releases have occurred at the facility within the past 5 years. However, at times minor cumulative releases do occur during filling of vehicles or equipment repair. This accumulation on ,the ground is removed periodically to prevent deeper infiltration into the ground. This facility is considered non -transportation -related on -shore and does not require a Facility Response Plan. This facility contains no more than 25,000 gallons of petroleum -based product and Protene, and does not transfer oil over bodies of water. Attachment B contains the Certification of the. Applicability of the Substantial Harm Criteria. �2S Spill Prevention Control and Counter Measure Plan (SPCC) Lee Iron & Metal Co. Page 3 The above ground storage tanks have been installed to meet North Carolina, "American Petroleum Institute and OSHA Requirements for Oil Storage Tanks," The tank support and foundation is visually inspected weekly by properly -trained personnel for any signs of deterioration or leaks which might cause a spill or accumulation of oil (I 12.7(c)). All unloading or transfer of fluids is done under constant supervision of the properly trained personnel (112.7(f)(1)). Any visible oil leaks that might be observed are promptly corrected (I 12.7(c)). All above ground valves, pipelines, and containers are inspected weekly by the properly trained personnel, and any deficiencies promptly reported and corrected (I 12.7(c)). A representative will attend the unloading of liquids at all times. No unloading will be conducted during inclement weather. The on-site-reptesentative will monitor anytime that the 1,000 gallon off -road diesel is being filled - by a delivery tank truck. The representative will ensure that the tank is not overfilled. Prior to filling and departure of any tank truck, the on -site representative will verify that all outlets of such vehicles are examined for leakage and if necessary ensure corrective measures are taken to prevent liquid leakage while in transit on the facility (I 12.7(h)(3)). A. sign (I 12.7(h)(2)) is provided in the unloading.area to warn delivery trailer drivers to disconnect flexible hose and close valves before moving the trailer. The on -site representative will verify disconnection before the tank truck departs (I 12.7(h)(3)). E's Spill Prevention Control and Counter Measure Plan (SPCC) Lee Iron & Metal Co. Page 4 AWN 1 . Inspection of the facility shall occur at a minimum of twice a year; once during the first half of the year (January to June) and once during the second half (July to December), with at least 60 days separating inspection dates. A written record of the periodic inspection signed by the Properly Trained Personnel shall be kept on file for a period of at least 3 years (112.7(c)). Attachment C.contains a copy of this inspection report. Periodic inspection will be conducted each time the 1,000 gallon off -road diesel tank is filled by the tanker truck. The tanks are secured by perimeter fencing and the entrance gates are locked when the tanks are unattended (I 12.7(g)(1)). The dispenser for the 1,000 gallon off -road is de -energized when in non - operation or non -standby status (I 12.7(g)(2)(3)). The loading/unloading connection should be securely capped when not in use (I 12.7(g)(4)). Lighting is present to provide visibility to identify possible leaks and releases (I 12.7(g)(5)).

The rate of flow, direction of flow, and quantity of liquids that could be discharged as a result of a release is provided below (I 12.7(b)). All of tanks are located in the rear of the processing/office building. The tanks are located on a concrete slab. A release from the tanks or tanker truck would spill on the concrete pad and then discharge to the grassed ditch. Maximum flow rate is estimated at 50 gpm. In general, any release would be absorbed by the grassed areas. However, a timely response will minimize potential cleanup costs, such as plugging the culverts and/or providing absorbent pads and booms along the ditches. Minor spills can be absorbed with dry granular absorbents, pads, or booms, Minor spills can be controlled by sweeping or mopping the material into approved containers for proper disposal. Proper disposal includes removing absorbent compounds from the floor on a timely basis. 62.S ATTACHMENT A: Vicinity Map �2� papal P Ilk ik WINN d1i 'fl-��5�(SU .die rl. ¢� ,�� f y, `f _ l 1, 4 7' Y, 'f ,`.`� � 'f'! -'—� •1 'Y^.. , . . . . . . . . . . . life t UL 2 ENGINEERING & ENVIRONMENTAL SCIENCE COMPANY N 3008 ANDERSON DR SUITE 102 RALEIGH, NORTH CAkbLINA 27609 (919) 781-7798 Vicinity Map DATE: Lee Iron & Metal Co. 2112/18 1085 Old US 421 1 I= 1k, 1.

Horner Blvd. Sanford, NC 27330 RE: Stormwater Evaluation Lee Iron & Metal Lillington Facility 1085 Old U.S. 421 Lillington, NC 27546 Dear Mr. Carpenter, RECEIVED MAR 02 2013 DENR-LAND QUALITY STORMWATER pERMITf ING Engineering & Environmental Science Company .(E2S) has completed the evaluation for the above referenced project. Following is a brief discussion of this project and our evaluation. Project Information At the Lee Iron & Metal Lill.ington Facility, minor scouring of the gravel surfaced parking/storage areas has occurred. Stormwater runoff with erosive velocities from the upslope areas is the likely cause of the scouring. Water Bars and Stone Check Dams In order to decrease the runoff velocity and reduce the potential for additional scouring, E2S' recommends the installation of water bars with maximum cross slopes of 1 %. The proposed water bars will consist of a 9" high compacted gravel ridge. The relatively flat cross slopes will attenuate the runoff velocity to non -erosive velocities of -less than 2 Wsec. The proposed water bars will discharge into an existing grass lined ditch located in the central portion of the property. ` Two (2) stone check dams are proposed to be installed in the existing ditch. The stone check dams will provide additional velocity attenuation and will decrease the amount of sediment being discharged from the property. The separately submitted 24"x36" drawing shows the proposed locations and details for the proposed water bars and check dams. Calculations for the water bars are provided in Attachment B. Stormwater Culvert and Surface Drains Currently the stormwater runoff being conveyed by the existing ditch discharges and flows overtop an existing drive. In order to prevent water overtopping the drive, E2S recommends installing a catch basin in the ditch with a 36" RCP culvert that discharges to the other side of the drive aisle. This proposed culvert can pass the 10-year rain event without overtopping. Outlet protection consisting of Class B Erosion Control Stone is proposed for the new culvert. Two (2) additional catch basins are proposed near the building. The catch basins will collect the surface runoff which will then be conveyed by 12" smooth walled corrugated plastic pipe before discharging into the ditch. The location and details for the proposed catch basins and culvert are provided on the accompanying 24"06" drawing. Calculations for the culvert are provided in Attachment B. Closure We appreciate serving you on this project. Please contact us if you have any further questions. Sincerely, �'� Q FSEAL T. Patrick Shillington, P. 15472�3 Robert W. Brantly, P.E.

From: Anen, Steven C Sent: Monday, April 30, 2018 10:58 AM To: Lawyer, Mike <mike.iawyer@ncdenr,gov> Subject: Lee Iron & Metal Co. Hi Mike, We got a stormwater permit application for Lee Iron & Metal Co. for an NCG20 (scrap metal). Their site description says that they process and recycle scrap metal from a variety of sources, including vehicles. They drain the fluids from the vehicles and use a crusher on site. From the aerial it looks like most of the site is used to store vehicles, which gives me the sense that automobile wrecking is a majority of what happens onsite, in which case I think that the site would be better covered under and NCG10 permit for automobile wrecking. I was wondering if you or someone from your office may be familiar with the site or has maybe spoken to the applicant. The site is at 1085 Old US 421, Lillington in Harnett County and the permit number is NCG200519. If you could give me any info I would greatly appreciate it.

Pape 1 1.0 .INTRODUCTION This "Spill and Prevention Control and Countermeasure Plan" (SPCC) is prepared in accordance with 40 CFR Paragraph 112.7 "General Requirements for Spill Prevention, Control, and Countermeasure Plans," July 1, 2008 Edition, where applicable. This plan is prepared for the Lee Iron & Metal facility in Lillington, NC (See Figure No.1 of Attachment A for location). The 24" by 36" Facility Stormwater Plan (112.7(a)(3)) drawing shows the subject site and facility. The Lee Iron & Metal facility is located in Lillington, Harnett County, NC. The facility is located on the south side of Old US 421. Other pertinent information for the facility includes: Address: 1085 Old US 421, Lillington, NC 27330 Phone: 919-775-7951 Latitude: 350 23' 38.7528" N Longitude: 78" 50' 34.5156" W The facility has one building that contains metal processing equipment and an office area. The Standard Industry Classification (SIC) Code for the facility is 5093 (Scrap Metal Recycling). Limited scrap metal moving equipment and vehicle refueling activities are conducted at the site. Five (5) above ground storage tanks (ASTs) are Iocated at the facility. These ASTs are described in further detail in Section 1.1. The facility accepts scrap metal and processes the material for recycling purposes. Commonly accepted materials include copper, steel, aluminum, scrap cars, and other raw metal materials. No hazardous or toxic materials of any kind are accepted at the facility. The scrap metal materials including vehicles are stockpiled in the gravel/grass areas outside of the building. The majority of the materials processing occurs within the building. Vehicles to be processed have fluids drained inside the building. The fluids are drained directly into barrels or other temporary storage containers. The liquids are then transferred to the above ground tanks located outside of the building. End of life vehicles are also processed by a crusher that is located outside of the building. 62s Spill Prevention Control and Counter Measure Plan (SPCC) Lee Iron & Metal Co. _ _ _ _ _ Page 2 i.1.AST and Seconclau Containment At the Lee Iron & Metal Facility, five (5) Above Ground Storage Tanks (AST's) are in -use that are outside of the plant buildings. The Storm Water Plan, Sheet No. 1, shows the locations of these tanks. These AST's include the following: • One (1) 200 gallon off -road diesel transfer tank • One (1) 1,000 gallon off -road diesel tank • One (1) 1,000 gallon used -gasoline tank • One (1) 1,000 gallon used oil tank • One (1) 1,000 gallon water and antifreeze tank The 1,000 gallon off -road diesel tank is used to refill the on -site equipment. The other tanks are used to store used gasoline, oil, and antifreeze, respectively, that is drained from vehicles that are brought to the facility to be scrapped. The 200 gallon off -road diesel tank is on wheels and is used to fill the crusher. This tank is,usually empty unless it is being used to transfer fuel to the crusher. All of the other tanks are double -walled for secondary containment purposes. 1.2 Secondary Containment for Delivery 'Wank Truck Unloading The 1,000 gallon off -road diesel tank ;rs the only AST at the facility that is filled by delivery tank truck unloading, and is the only tank -used to (tensed product. An on -site representative should monitor anytime that the 1,000 gallon off -road diesel is being filled by a delivery tank truck, and ensure that the tank is not overfilled. In general, any release would be absorbed by the grassed areas before leaving the property. However, a timely response will minimize potential cleanup costs, such as plugging the culvert and/or providing absorbent pads and booms along the ditch. 1.3 Past Release Documentation No past releases have occurred at the facility within the past 5 years. However, at times minor cumulative releases do occur during filling of vehicles or equipment repair. This accumulation on .the ground is removed periodically to prevent deeper infiltration into the ground. 1.4 A licabili of Substantial Harm This facility is considered non -transportation -related on -shore and does not require a Facility Response Plan. This facility contains no more than 25,000 gallons of petroleum -based product and Protene, and does not transfer oil over bodies of water. Attachment B contains the Certification of the Applicability of the Substantial Harm Criteria. E2s Spill Prevention Control and Counter Measure Plan (SPCC) Lee Iron & Metal Co.

Carolina, "American Petroleum Institute and OSHA Requirements for Oil Storage Tanks." The tank support and foundation is visually inspected weekly by properly -trained personnel for any signs of deterioration or leaks which might cause a spill or accumulation of oil (112.7(c)). All unloading or transfer of fluids is done under constant supervision of the properly trained personnel (112.7(f)(1)). Any visible oil leaks that might be observed are promptly corrected (112.7(c)). 2.2 'Facilities Transfer Operations Pumping and In lent Process All above ground valves, pipelines, and containers are inspected weekly by the properly trained personnel, and any deficiencies promptly reported and corrected (112.7(c)). 2.3 Facili Tank Car and Truck Loading/UnloadingLoading/Unloading Rack A representative will attend the unloading of liquids at all times. No unloading will be conducted during inclement weather. The on-site'reptesentative will monitor anytime that the 1,000'gallon off -road diesel is being filled" by a delivery tank truck. The representative will ensure that the tank is not overfilled. Prior to filling and departure of any tank truck, the on -site representative will verify that all outlets of such vehicles are examined for leakage and if necessary ensure corrective measures are taken to prevent liquid leakage while in transit on the facility (112.7(h)(3)). A sign (112.7(h)(2)) is provided in the unloading,area to warn delivery trailer drivers to disconnect flexible hose and close valves before moving the trailer. The on -site representative will verify disconnection before the tank truck departs (112.7(h)(3)). 62S Spill Prevention Control and Counter Measure Plan (SPCC) Lee Iron & Metal Co. Pane 4 3.0 INSPECTION AND RECORDS Inspection of the facility shall occur at a minimum of twice a year; once during the first half of the year (January to June) and once during the second half (July to December), with at least 60 days separating inspection dates. A written record of the periodic inspection signed by the Properly Trained Personnel shall be kept on file for a period of at least 3 years (I 12.7(c)). Attachment C contains a copy of this inspection report. Periodic inspection will be conducted each time the 1,000 gallon off -road diesel tank is filled by the tanker truck. 4.0 SECURITY The tanks are secured by perimeter fencing and the entrance gates are locked when the tanks are unattended (I 12.7(g)(1)). The dispenser for the 1,000 gallon off -road is de -energized when in non - operation or non -standby status (112.7(g)(2)(3)). The loading/unloading connection should be securely capped when not in use (112.7(g)(4)). Lighting is present to provide visibility to identify possible, leaks and releases (I 12.7(g)(5)). 5.0 PERSONNEL TRAINING AND SPILL PREVENTION PROCEDURE The personnel shall be properly trained and instructed on the operation and maintenance procedures of the spill prevention equipment and the applicable pollution control laws, rules and regulations 012.7(0). The Properly Trained Personnel have been designated responsible for oil spill prevention (112.7(f)). The operation personnel conduct periodic spill prevention briefings in intervals frequent enough (at least annually) to assure adequate understanding of the SPCC plan for the facility (112.7 (f) of Guidelines). Such briefings should highlight and describe known failures or malfunctions.

Horner Blvd. Sanford, NC 27330 RE: Stormwater Evaluation Lee Iron & Metal Lillington Facility 1085 OId U.S. 421 Lillington, NC 27546 Dear Mr. Carpenter, RECENEC MAR 0 2 2013 DeNR-LAND QUALITY STORMWATER PERMITTING Engineering & Environmental Science Company (E2S) has completed the evaluation for the above referenced project. Following is a brief discussion of this project and our evaluation. Project Information At the • Lee Iron & Metal Lillington Facility, minor scouring of the gravel surfaced parking/storage areas has occurred. Stormwater runoff with erosive velocities from the upslope areas is the likely cause of the scouring. Water Bars and Stone Check Dams In order to decrease the runoff velocity and reduce the potential for additional scouring, E2S recommends the installation of water bars with maximum cross slopes of 1%. The proposed water bars will consist of a 9" high compacted gravel ridge. The relatively flat cross slopes will attenuate the runoff velocity to non -erosive velocities of less than 2 ft/sec. The proposed water bars will discharge into an existing grass lined ditch located in the central portion of the property. Two (2) stone check dams are proposed to be installed in the existing ditch. The stone check dams will provide additional velocity attenuation and will decrease the amount of sediment being discharged from the property. The separately submitted 24"06" drawing shows the proposed locations and details for the proposed water bars and check dams. Calculations for the water bars are provided in Attachment B. Stormwater Culvert and Surface Drains Currently the stormwater runoff being conveyed by the existing ditch discharges and flows overtop an existing drive. In order to prevent water overtopping the drive, E2S recommends installing a catch basin in the ditch with a 36" RCP culvert that discharges to the other side of the drive aisle. This proposed culvert can pass the 10-year rain event without overtopping. Outlet protection consisting of Class B Erosion Control Stone is proposed for the new culvert. Two (2) additional catch basins are proposed near the building. The catch basins will collect the surface runoff which will then be conveyed by 12" smooth walled corrugated plastic pipe before discharging into the ditch. The location and details for the proposed catch basins and culvert are provided on the accompanying 24"06" drawing. Calculations for the culvert are provided in Attachment B. Closure We appreciate serving you on this project. Please contact us if you have any further questions. Sincerely, :'o"`c`ROli'',�, :�� r Q 7", � ssnt 3 T. Patrick Shillington, P. - 154-N Robert W.
