This permit is issued pursuant to the requirements of North Carolina General Statute 143-215 .1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection agency dated October 15, 2007 (or as subsequently amended). This final permit includes minor changes from the draft permit sent to you on September 23, 2009. We received a letter dated November 18, 2009.requesting reconsideration of the proposed new analytical testing requirements. A site visit was conducted by Corey Basinger of the Winston Salem Regional Office to help evaluate the request. The analytical monitoring has been revised to eliminate the Total Copper, Total Zinc, and TPH monitoring but now includes Total Aluminum. The letter proposed four specific changes the facility needs to perform or has performed in order to reduce the possibility of spillage. Please perform or maintain the following changes or TPH may be added back into the permit upon the next regional office inspection: 1. S1 Waste oil drum storage would be moved indoors. 2. S2 5000 gallon tank (not used) would be disposed of or removed for site. 3. S3 Recycled water glycol tote storage has already been moved indoors 4. S4 & S5 compressor oil drums (one at each location) are already under roof but could be moved indoors if required. The qualitative monitoring strategy remains the same (semi-annual) as the draft permit. Failure to complete the monitoring as required is a violation of the permit and any permit noncompliance constitutes a violation of the Clean Water Act. Reference Part III, Section A, Item 2 "Duty to Comply", Item 9 "Penalties for Tampering " and Item 10 "Penalties for Falsification of Reports" of your permit for further information. If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter.

This Plan shall be considered public information in accordance with Part III, Standard Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a minimum, the following items: 1. Site PIan. The site plan shall provide a description of the physical facility and the potential pollutant sources which 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 stotmwater 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 longitudebfthe 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 which -could be expected:to-be present in the stormwater discharge from each outfall. (c) A site map drawn to scale (including a distance legend) showing: 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, and impervious surfaces. The site map must indicate the percentage of each drainage area that is impervious. (d) A list of significant spills or Ieaks of pollutants that have occurred at the facility during the three (3) previous 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 11I, Standard Conditions, Section Part II Page I of 9 Permit No. NCS000158 B, Paragraph 5. The.permittee shall re -certify annually that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. 2. Stormwater Management Plan. The stonnwater management plan shall contain a narrative description of the materials management practices employed which control or minimize the exposure of significant materials to stonnwater, including structural and nonstructural measures. The stonnwater management plan, at a minimum, shall incorporate the following: , (a) Feasibility Study. 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. Wherever practical, the pennittee shall prevent exposure of all storage areas, material handling operations, and manufacturing or fueling operations. In areas where elimination of exposure is not practical, the stormwater management plan shall document the feasibility of diverting the stonnwater runoff away from areas of potential contamination. (b) 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 stonnwater 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 stonnwater. Accumulated stonnwater 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 years. (c) BMP Summary. A listing of site structural and non-structural Best Management Practices (BMP) shall be provided. The installation and implementation of BMPs shall be based on the assessment of the potential for sources to contribute significant quantities of pollutants to stormwater discharges and data collected through monitoring of stormwater discharges. The BMP Summary shall include a written record of the specific rationale for installation and implementation of the selected site BMPs. The BMP Summary shall be reviewed and updated annually. 3. 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 Part II Page 2 of 9 Permit No. NCS000158 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. 4. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and good housekeeping program shall be developed. The program shall list all stonnwater control systems, stormwater.discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial activity areas (including material storage areas, material handling areas, disposal areas, process areas, loading and unloading areas, and haul roads), all drainage features and structures, and existing structural BMPs. The program shall establish schedules of inspections, maintenance, and housekeeping activities -of stormwater control systems, as well as facility equipment, facility areas, and facility systems that present a potential for stormwater exposure or stonnwater pollution. Inspection of material handling areas and regular cleaning schedules of these areas shall be incorporated into the program. Timely compliance with the established schedules for inspections,'maintenance, and housekeeping shall be recorded in writing and maintained in the SPPP. 5. 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. FaciIity-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. 6. _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. 7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in design, construction, operation, or maintenance which 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 years, or the notation that no spills have occurred. The annual update shall include written re -certification that the stonnwater 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 Stonnwater 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 penmittee shall Part II Page 3 of 9 Permit No. NCSOOo158 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 III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes have been made. 8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of the Preventative Maintenance and Good Housekeeping Program at a minimum on a semi-annual schedule, 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 (unless performed more frequently than semi-annually). These facility inspections are different from, and in addition to, the stonnwater discharge characteristic monitoring required in Part It B and C of this pen -nit. 9. Implementation. The permittee shall implement the Plan. 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 in 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. Part I l Page 4 of 9 Permit No. NCS000158 SECTION B: ANALYTICAL MONITORING REQUIREMENTS Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All analytical monitoring shall be performed during a representative storm event. The required monitoring will result in a minimum of ten analytical samplings being conducted over the term of the permit at each stormwater discharge outfall (SDO). A representative storm event 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 .72 hours. A single storm event may have a period of no precipitation of 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. Table 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. 5. 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. Tier Two If: During the term of this permit, the first valid sampling results from two consecutive monitoring periods are above the benchmark values, or outside of the benchmark range, for any specific parameter at a 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 consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three consecutive sample results are below the benchmark values or within the benchmark range. 3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly monitoring report indicating "No Flow' to comply with reporting requirements. 4. Maintain a record of the Tier Two response in the Stormwater Pollution Prevention Plan. During the term of this permit, if the valid sampling results required for the pen -nit monitoring periods exceed the benchmark value, or are outside the benchmark range, for any specific parameter at any specific outfall on three occasions, the permittee sball notify the DWQ Regional Office Supervisor in writing within 30 days of receipt of the third 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; require the permittee to install structural stormwater controls; require the permittee to implement other stormwater control measures; or • require that the permittee implement site modifications to qualify for the No Exposure Exclusion. Part Il Page 7 of 9 .:'� ' . - Permit No. NCS000158 SECTION C: QUALITATIVE MONITORING REQUIREMENTS Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of representative outfall status and shall be performed as specified in Table 4, during the analytical monitoring event. Qualitative monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution Prevention Plan (SPPP) and -assessing new sources of stormwater pollution. In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall document the suspected cause of the condition and any actions taken in response to the discovery.

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 years. (c) BMP Summary. A listing of site structural and non-structural Best Management Practices (BMP) shall be provided. The installation and implementation of BMPs shall be based on the assessment of the potential for sources to contribute significant quantities of pollutants to stormwater discharges and data collected through monitoring of stormwater discharges. The BMP Summary shall include a written record of the specific rationale for installation and implementation of the selected site BMPs. The BMP Summary shall be reviewed and updated annually. 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 Part !I Page 2 of 9 Permit No. NCS000158 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. 4. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and good housekeeping program shall be developed. The program shall list all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial activity areas (including material storage areas, material handling areas, disposal areas, process areas, loading and unloading areas, and haul roads), all drainage features and structures, and existing structural BMPs. The program shall establish schedules of inspections, maintenance, and housekeeping activities of stormwater control systems, as well as facility equipment, facility areas, and facility systems that present a potential for stormwater exposure or stormwater pollution. Inspection of material handling areas and regular cleaning schedules of these areas shall be incorporated into the program. Timely compliance with the established schedules for inspections, maintenance, and housekeeping shall be recorded in writing and maintained in the SPPP. 5. 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.

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. 7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in design, construction, operation, or maintenance which 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 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 Parti l Page 3 of 9 Permit No. NCS000158 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 I1I, Standard Conditions, Section B, Paragraph 5) to the Director that the changes have been made. 8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of the Preventative Maintenance and Good Housekeeping Program at a minimum on a semi-annual schedule, 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 (unless performed more frequently than semi-annually). These facility inspections are different from, and in addition to, the stormwater discharge characteristic monitoring required in Part II B and C of this permit. 9. Implementation. The permittee shall implement the Plan. 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.

Part I I Page 4 of 9 Permit No. NCSOOO 158 SECTION B: ANALYTICAL MONITORING REQUIREMENTS Analytical monitoring of stormwater discharges shall be performed as specified in Table L All analytical monitoring shall be performed during a representative storm event. The required monitoring will result in a minimum of ten analytical samplings being conducted over the term of the permit at each stormwater discharge outfall (SDO). A representative storm event 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 72 hours. A single storm event may have a period of no precipitation of 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. Table 1.

Part 11 Page 4 of 9 Permit No. NCS000158 SECTION B: ANALYTICAL MONITORING REQUIREMENTS Analytical monitoring of stormwater discharges shall be perforted as specified in Table 1. All analytical monitoring shall be performed during a representative storm event. The required monitoring will result in a minimum of ten analytical samplings being conducted over the term of the permit at each stormwater discharge outfall (SDO). A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The tune between this storm event and the previous storm event measuring greater than 0.1 inches must be at leas;. 72 hours. A single storm event may have a period of no precipitation of up to IO.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. Table 1.
