Regulatory citations have been added to the permit. 3. Outfall map has been updated. 4. Facility address has been updated on the cover sheet per the renewal application. 5. Receiving stream characteristics have been updated on the Supplement to Permit Cover Sheet. 6. The facility grade and parameter codes have been added in Sections A. (1), A. (2), and A. (3). 7. Monitoring for copper and chlorides has been removed in Section A. (2) per the reasonable potential analysis. 8. Monitoring for total hardness has been added in Section A. (3). 9. Footnotes for total residual chlorine have been added in Section A. (1) and updated in Sections A. (2) and A. (3). 10. Toxicity testing language has been updated in Sections A. (4) and A. (5). 11. Language in Section A. (7) has been updated. Please note that the receivingstream for Outfall 002 is listed as an impaired waterbodyon the North p Carolina 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then mitigative measures may be required. QEQ North Carolina Department of Environmental Quality I Division of Water Resources 1617 Mail Service Center I Raleigh,North Carolina 27699-1617 919-707-9000 The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC Environmental Management Committee(EMC) on November 13, 2014. The US EPA subsequently approved the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water Resources NPDES Permitting Unit is required to implement the new dissolved metal standards in all permits public noticed after April 6, 2016. The new standards for most metals include acute standards. Further, the freshwater standards for several metals are expressed as the dissolved form of the metals, and seven metals have hardness-dependent equations. As a result, the NPDES Permitting Unit will need site-specific effluent hardness data and instream hardness data, upstream of the discharge, for each facility monitoring these metals in order to calculate permit limitations. Effluent hardness and instream hardness sampling, upstream of the discharge, has been added to this permit at a monitoring frequency of quarterly. See Sections A. (2) and A. (3) Effluent Limitations and Monitoring Requirements. With this notification, the Division will solicit public comment on this draft permit by publishing a notice in newspapers having circulation in the general Cabarrus County area, per EPA requirements. Please provide your comments, if any, to me no later than 30 days after receiving this draft permit. Following the 30-day public comment period, the Division will review all pertinent comments and take appropriate action prior to issuing a final permit. If you have questions concerning the draft, please contact me at 919-707-3619, or via e-mail [Brianna.Young@ncdenr.gov].

(7) STORMWATER MONITORING, CONTROLS,AND LIMITATIONS FOR PERMITTED DISCHARGES [143-215(a)] FINAL LIMITATIONS AND CONTROLS FOR STORMWATER DISCHARGES No later 180 days prior the expiration date of this permit, the permittee shall submit an NPDES stormwater permit application to the Division of Energy, Mineral, and Land Resources (DEMLR). During the period beginning on the effective date of the permit and lasting until expiration, the permittee is authorized to discharge stormwater associated with industrial activity from outfalls 001 and 002. Such discharges shall be controlled, limited, and monitored as specified below: 1. Stormwater Pollution Prevention Plans The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). The SPPP shall be maintained on site unless exempted from this requirement by the Division. The SPPP is public information in accordance with Part II, Section E.10. of this permit. The SPPP shall include, at a minimum, the following items: a) Site Overview. The Site Overview shall provide a description of the physical facility and the potential pollutant sources that may be expected to contribute to contamination of stormwater discharges. The Site Overview 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 waters to which the stormwater outfalls discharge, or if the discharge is to a municipal separate storm sewer system, the name of the municipality and the ultimate receiving waters; and accurate latitude and longitude of the points of stormwater discharge associated with industrial activity. The general location map (or alternatively the site map) shall identify whether any receiving waters are impaired (on the state's 303(d) list of impaired waters) or if the site is located in a watershed for which a TMDL has been established, and what the parameters 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 Page 11of19 Permit NC0086169 practices. A narrative description of the potential pollutants that could be expected to be present in the stormwater discharge from each outfall. c. A site map drawn at a scale sufficient to clearly depict: the site property boundary; the stormwater discharge outfalls; all on-site and adjacent surface waters and wetlands; industrial activity areas (including storage of materials, disposal areas, process areas, loading and unloading areas, and haul roads); site topography and finished grade; all drainage features and structures; drainage area boundaries and total contributing area for each outfall; direction of flow in each drainage area; industrial activities occurring in each drainage area; buildings; stormwater Best Management Practices (BMPs); and impervious surfaces. The site map must indicate the percentage of each drainage area that is impervious, and the site map must include a graphic scale indication and north arrow. d. A list of significant spills or leaks of pollutants during the previous three (3) years and any corrective actions taken to mitigate spill impacts. e. Certification that the stormwater outfalls have been evaluated for the presence of non- stormwater discharges. The permittee shall re-certify annually 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 II, Section B.11. b) Stormwater Management Strategy. The Stormwater Management Strategy shall contain a narrative description of the materials management practices employed which control or minimize the stormwater exposure of significant materials, including structural and nonstructural measures. The Stormwater Management Strategy, 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 rainfall and run-on flows. Wherever practical, the permittee shall prevent exposure of all storage areas, material handling operations, and manufacturing or fueling operations. In areas where elimination of exposure is not practical, this review shall document the feasibility of diverting the stormwater run-on 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 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). 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 Page 12 of 19 Permit NC0086169 the observation, the description of the accumulated stormwater, and the date and time of the release shall be kept for a period of five (5) years. c. BMP Summary. A listing of site structural and non-structural Best Management Practices (BMPs) 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 on 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. c) Spill Prevention and Response Procedures. The Spill Prevention and Response Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel responsible for implementing the SPRP shall be identified in a written list incorporated into the SPRP and signed and dated by each individual acknowledging their responsibilities for the plan. A responsible person shall be on-site at all times during facility operations that have the potential to contaminate stormwater runoff through spills or exposure of materials associated with the facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure plan(SPCC) may be a component of the SPRP, but may not be sufficient to completely address the stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be incorporated by reference into the SPRP. d) Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and good housekeeping program shall be developed and implemented. The program shall address all stormwater control systems (if applicable), 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 where not already addressed under another element of the SPPP. 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 and maintained in the SPPP. e) 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 at the outfalls required in Part A. (7.)(2.) of this Section(Qualitative Monitoring). f) 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 Page 13 of 19 Permit NC0086169 to contaminate stormwater runoff. The facility personnel responsible for implementing the training shall be identified, and their annual training shall be documented by the signature of each employee trained. g) Responsible Party. The SPPP shall identify a specific position or positions responsible for the overall coordination, development, implementation, and revision of the SPPP. Responsibilities for all components of the SPPP shall be documented and position assignments provided. h) SPPP Amendment and Annual Update. The permittee shall amend the SPPP whenever there is a change in design, construction, operation, site drainage, maintenance, or configuration of the physical features which may have a significant effect on the potential for the discharge of pollutants to surface waters. All aspects of the SPPP shall be reviewed and updated on an annual basis. The annual update shall include: a. an updated list of significant spills or leaks of pollutants for the previous three (3) years, or the notation that no spills have occurred (element of the Site Overview); b. a written re-certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges (element of the Site Overview); c. a documented re-evaluation of the effectiveness of the on-site stormwater BMPs (BMP Summary element of the Stormwater Management Strategy). d. a review and comparison of sample analytical data to benchmark values (if applicable) over the past year, including a discussion about Tiered Response status. The permittee shall use the Annual Summary Data Monitoring Report (DMR) form, available from the Stormwater Permitting Program's website(See `Monitoring Forms' here: https://deq.nc.gov/about/divisions/energy-mineral-1 and-resources/npdes-industrial- stormwater). i) The Director may notify the permittee when the SPPP does not meet one or more of the minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit a time schedule to the Director for modifying the SPPP to meet minimum requirements. The permittee shall provide certification in writing (in accordance with Part II, Section B.1 1.) to the Director that the changes have been made. j) SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention Plan and all appropriate BMPs to prevent contaminants from entering surface waters via stormwater. Implementation of the SPPP shall include documentation of all monitoring, measurements, inspections, maintenance activities, and training provided to employees, including the log of the sampling data and of actions taken to implement BMPs associated with the industrial activities, including vehicle maintenance activities. Such documentation shall be kept on-site for a period of five(5) years and made available to the Director or the Director's authorized representative immediately upon request. 2. Qualitative Monitoring Requirements Qualitative monitoring requires a qualitative visual inspection of each stormwater outfall, regardless of representative outfall status, for the purpose of evaluating the effectiveness of the Stormwater Pollution Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests are required. Qualitative monitoring of stormwater outfalls must be performed semi-annually Page 14 of 19 Permit NC0086169 during a measurable storm event(unless the permittee is required to perform further qualitative sampling per the Qualitative Monitoring Response, below). A measurable storm event is a storm event that results in an actual discharge from the permitted site outfall. The previous measurable storm event must have been at least 72 hours prior. The 72- hour storm interval does not apply if the permittee is able to document that a shorter interval is representative for local storm events during the sampling period, and the permittee obtains approval from the local Regional Supervisor(See Part V., Definitions). Inability to sample because of adverse weather conditions must be documented in the SPPP and recorded on the DMR (see Adverse Weather in Part V., Definitions). Only SDOs discharging stormwater associated with industrial activity must be monitored(see Part V., Definitions). 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. This documentation will be maintained with the SPPP. Stormwater Discharge Characteristics Frequency 1 Monitoring Type 2 Monitoring Location 3 Color Semi-annual Visual SDO Odor Semi-annual Observation SDO Clarity Semi-annual Visual SDO Floating Solids Semi-annual Visual SDO Suspended Solids Semi-annual Visual SDO Foam Semi-annual Visual SDO Oil Sheen Semi-annual Visual SDO Other obvious indicators of Semi-annual Visual SDO stormwater pollution 1. Frequency: The first qualitative observation during the term of the permit must be performed within the first six months of the permit term and during the initial analytical monitoring event(applicable to outfall 002). All subsequent qualitative monitoring will be performed twice per year(spaced at least 60 days apart) during a measureable storm event. 2. Monitoring Type: Monitoring requires a qualitative observation of each stormwater outfall. No analytical testing or sampling is required. 3. SDO: effluent at outfalls 001 and 002. A minimum of 60 days must separate monitoring events, unless additional sampling has been instituted as part of the Qualitative Monitoring Response below. If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or that significant stormwater contamination is present, the permittee shall investigate potential causes, evaluate the feasibility of corrective actions, and implement those corrective actions within 60 days, per the Qualitative Monitoring Response that follows. A written record of the permittee's investigation, evaluation, and response actions shall be kept in the Stormwater Pollution Prevention Plan. Page 15 of 19 Permit NC0086169 Qualitative Monitoring Response Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, assessing new sources of stormwater pollution, and prompting the permittee's response to pollution. If the permittee repeatedly fails to respond effectively to correct problems identified by qualitative monitoring, or if the discharge causes or contributes to a water quality standard violation, DWR may but is not limited to: • require that the permittee revise, increase, or decrease the monitoring frequency (analytical or qualitative) for the remainder of the permit; • require the permittee to install structural stormwater controls; • require the permittee to implement other stormwater control measures; • require the permittee to perform upstream and downstream monitoring to characterize impacts on receiving waters; or • require the permittee implement site modifications to qualify for a No Exposure Exclusion. A. (8) ANNUAL SHUTDOWN PROCEDURES CONDITION [G.S. 143-215.1(b)] On an annual basis, the permittee is permitted to discharge up to 250,000 gallons of non-contact cooling water and flush water, from the two cooling tower basins, through Outfall 002. The semi-annual monitoring associated with Outfall 002 shall coincide with this event. Corning Incorporated shall develop a HVAC Cooling Tower Shutdown Procedure consistent with Betz-Dearborn recommendations. The HVAC Cooling Tower Shutdown Procedure should include the condition that both cooling towers will not be flushed at the same time. This procedure shall be kept on site and available for review by Division staff upon request. Additionally, the time and duration for the discharge of non-contact cooling water through Outfall 002 shall be recorded in the operations log by the Operator in Responsible Charge and available for review by the Division upon request. A. (9) ELECTRONIC REPORTING OF MONITORING REPORTS [NCGS 143-215.1 (b)] Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015. NOTE: This special condition supplements or supersedes the following sections within Part II of this permit(Standard Conditions for NPDES Permits): • Section B. (11.) Signatory Requirements • Section D. (2.) Reporting • Section D. (6.) Records Retention • Section E. (5.) Monitoring Reports Page 16 of 19 Permit NC0086169 1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1 The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application. Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet. Until such time that the state's eDMR application is compliant with EPA's Cross-Media Electronic Reporting Regulation(CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DEQ/Division of Water Resources/Water Quality Permitting Section ATTENTION: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See "How to Request a Waiver from Electronic Reporting" section below. Regardless of the submission method, the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. Starting on December 21,2020, the permittee must electronically report the following compliance monitoring data and reports, when applicable: • Sewer Overflow/Bypass Event Reports; • Pretreatment Program Annual Reports; and • Clean Water Act (CWA) Section 316(b) Annual Reports. The permittee may seek an electronic reporting waiver from the Division (see"How to Request a Waiver from Electronic Reporting" section below). 2. Electronic Submissions In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of each electronic submission. The permittee should use the EPA's website resources to identify the initial recipient for the electronic submission. Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)]. Page 17 of 19 Permit NC0086169 EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each type of electronic submission and for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well. Information on EPA's NPDES Electronic Reporting Rule is found at: https://www.federalregister.gov/documents/2015/10/22/2015-24954/national_pollutant- discharge-elimination-system-npdes-electronic-reporting-rule. Electronic submissions must start by the dates listed in the"Reporting Requirements" section above. 3. How to Request a Waiver from Electronic Reporting The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the Division. Requests for temporary electronic reporting waivers must be submitted in writing to the Division for written approval at least sixty(60) days prior to the date the facility would be required under this permit to begin submitting monitoring data and reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be submitted electronically to the Division unless the permittee re-applies for and is granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not transferrable. Only permittees with an approved reporting waiver request may submit monitoring data and reports on paper to the Division for the period that the approved reporting waiver request is effective. Information on eDMR and the application for a temporary electronic reporting waiver are found on the following web page: http://deq.nc.gov/about/divisions/water-resources/edmr 4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1 All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II, Section B. (11.)(b). A person, and not a position, must be delegated signatory authority for eDMR reporting purposes. For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user account and login credentials to access the eDMR system. For more information on North Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit the following web page: http://deq.nc.gov/about/divisions/water-resources/edmr Certification. Any person submitting an electronic DMR using the state's eDMR system shall make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION WILL BE ACCEPTED: "I certify, under penalty of law, 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. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the Page 18 of 19 Permit NC0086169 information submitted is, to the best of my knowledge and belief true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fines and imprisonment for knowing violations." 5. Records Retention [Supplements Section D. (6.)] The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions. These records or copies shall be maintained for a period of at least 3 years from the date of the report. This period may be extended by request of the Director at any time [40 CFR 122.41].
