Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge from any conveyance that is used for collecting and conveying storm water and that is directly related to manufacturing,processing or raw materials storage areas at an industrial plant. The term does not Page 2 of 10 include discharges from facilities or activities excluded from the NPDES program under this part 122. For the categories of industries identified in this section, the term includes, but is not limited to, storm water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled by carriers of raw materials, manufactured products, waste material, or byproducts used or created by the facility; material handling sites; refuse sites; sites used for the application or disposal of process waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of material handling equipment; sites used for residual treatment, storage, or disposal; shipping and receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and intermediate and final products; and areas where industrial activity has taken place in the past and significant materials remain and are exposed to storm water. For the purposes of this paragraph, material handling activities include storage, loading and unloading, transportation, or conveyance of any raw material, intermediate product, final product, byproduct or waste product. The term excludes areas located on plant lands separate from the plant's industrial activities, such as office buildings and accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm water [sic] drained from the above described areas." Section 2. Monitoring Information and Compliance History: • November 2018 to June 2023, benchmarks exceeded for: o North: COD Ix • Annual samples for 2019, 2020, 2021, and 2022 were provided for numerous other chemicals (see attachment in permit application). • Permit renewal application(Table B of the application)provided parameters monitored for as part of the facility's wastewater permit NC0004952, however, these are not expected to be present in the stormwater discharge • Per the November 2023 inspection report: o Facility records were not well organized. The version of the SWPPP provided during the inspection had not been reviewed within the last year and training records were not available. After the inspection, permittee provided a more recent version of the plan that had been reviewed within the last year and training records were provided shortly after the inspection by email. o The facility is conducting analytical monitoring and qualitative monitoring. However, better follow up is needed for potential issues identified in the qualitative monitoring. Section 3. Proposed Monitoring for Stormwater Discharges: The Division considered potential pollutants from past and present industrial activities and data was submitted for November 2018 to June 2023. Quantitative sampling included pH, TSS, BOD, and COD. Annual samples for 2019, 2020, 2021, and 2022 were provided for numerous other chemicals (see attachment in permit application). Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases, dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the proposed monitoring for each outfall at the CNA Holdings— Shelby site.

Stormwater benchmarks are numerical action levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark concentrations are intended as guidelines for the facility's development and implementation of the Stormwater Pollution Prevention Plan(SWPPP). Benchmark exceedances require the permittee to increase monitoring, increase management actions, increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a tiered approach to specify actions the permittee must take in response to analytical results above benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide flexibility to address issues that may arise with one or more parameters and/or outfalls. Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of DWR. NC DWR follows established federal procedures for calculating acute standards when developing the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L. Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this approach because of the ephemeral nature of rainfall events. The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or ash removal in specific drainage areas at this site. For parameters that do not have a stormwater benchmark, the Division may develop a benchmark value if appropriate toxicity data become available or if rising trends in concentrations suggest a persistent source. A summary of the benchmarks in the draft permit, and their basis, is below: Page 5 of 10 Parameter Benchmark Basis Total Suspended 100 mg/L National Urban Runoff Program(NURP) Study, 1983 Solids TSS H 6 s.u. —9 s.u. NC Water Quality Standard(Range) Non-Polar Oil & Review of other state's daily maximum benchmark Grease 15 mg/L concentration for this more targeted O&G;NC WQS that EPA Method 1664 does not allow oil sheen in waters SGT-HEM BOD 30 mg/L BPJ; Based on Secondary Treatment Regulation(40 CFR 133.03 COD 120 mg/L BPJ; Generally found at levels 4x BOD5 in domestic wastewaters Copper Total 10 µg/L Acute Aquatic Criterion, '/2 FAV Lead Total 75 /L Acute Aquatic Criterion, '/2 FAV Zinc (Total) 126 µg/L Acute Aquatic Criterion, '/2 FAV Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's pollution prevention approach to stormwater permitting. The Division's maintains that implementation of Best Management Practices (BMPs) and traditional stormwater management practices that control the source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are designed to be flexible requirements for implementing site-specific plans to minimize and control pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT. Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an alternative monitoring plan for approval by the Region: • Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional Engineer may direct the response actions on the part of the permittee as provided in Tier Three, including reduced or additional sampling parameters or frequency. • If pursuing the alternative above after two consecutive exceedances, the permittee may propose an alternative monitoring plan for approval by the Regional Engineer. The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For example, the permittee may request that mercury only be monitored semi-annually under the tiers, or that only parameters over the benchmark be monitored more frequently. In this way, changes to the monitoring scheme for any outfall could be handled outside of a permit modification. Other Proposed Requirements: • It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an annual certification that stormwater outfalls have been evaluated for the presence of non- Page 6 of 10 stormwater discharges, and if any are identified, how those discharges are permitted or otherwise authorized. • Requirement to submit a request for permit modification if the facility identifies or creates any new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants. • The Division expects the permittee to apply best professional judgment and consider the safety of its personnel in fulfilling sampling obligations under the permit. • Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a state does not establish a system to receive such submittals, then permittees must submit DMRs electronically to the EPA. • Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout year. Section 4. Changes from previous permit to draft: • Monitoring increased from semi-annually to quarterly for all parameters (qualitative and quantitative) • "No discharge" clarifications made • Feasibility study requirement removed per updated stormwater program requirements • eDMR requirement added • Boilerplate language moved into body of the permit; boilerplate no longer attached • Outfall-specific monitoring been implemented to reflect industrial activity and potential pollutants specific to each discharge area • Monitoring for total copper, total lead, and total zinc added for outfall SWO02 due to storage of scrap metals outdoors • Monitoring for total hardness added for outfalls where monitoring for hardness dependent metals is required • Benchmarks updated for parameters per guidance from DWR Standards group on stormwater benchmarks Section 5. Changes from draft to final: • Regulatory citations have been added • Annual online SWPPP certification removed from Part B o Mistakenly included in draft permit • Outfall descriptions for SW001 (EAST) and SWO03 (SOTH)have been updated Section 6. Discussions with the Facility and Regional Office: • Initial contact with facility: 9/22/2023 • Initial contact with Regional Office: 9/22/2023 • Draft sent to CO peer review: N/A • Draft sent to Regional Office: 1/4/2024 • Final permit sent for supervisor signature: Page 7 of 10 Section 7. Comments received on draft permit: • Melissa Bamford (Trinity Consultants on behalf of permittee; via email 2/2/2024): o Update outfall IDs as follows in Table 1 title and outfall description to be consistent with Permit Summary information: ■ East outfall ID changed from "SW001"to "EAST" ■ South outfall ID changed from"SW003"to "SOTH" ■ DEMLR response: Outfalls must be assigned a numeric value in order for NC DEQ to transfer monitoring data from the state's database to the US EPA's database. The outfall denotation provided during the renewal process is still included in the permit to ensure clarity in reporting monitoring data for the correct outfall. o Add the following footnote to the Non-polar oil & grease monitoring line item to clarify that monitoring is only required in vehicle or equipment maintenance areas with>55 gallons/month of oil: "Monitoring for Non-Polar Oil & Grease is only required in vehicle or equipment maintenance areas in which more than 55 gallons of new motor oil and/or hydraulic oil per month is used when averaged over the calendar year." ■ DEMLR response: Monitoring for non-polar oil and grease is no longer required in only vehicle maintenance areas. This is a programmatic update. If more than 55 gallons (averaged) of oil are used per month, whether it's used for vehicle maintenance, equipment maintenance, or other usage, monitoring is required. o Update outfall descriptions under Table 1 (Page 14) as follows: ■ Outfall SW001 EAST (East): Drainage area consists of loading and unloading activities, Marley cooling tower, 300 gallons of caustic, 120 gallons of boiler treatment, 120 gallons of oxygen scavenger, 120 gallons of corrosion inhibitor, 120 gallon of bromine, 120 gallons of biocide, and 120 gallons of cooling tower treatment, decommissioned tank farm and unloading station, decommissioned south tank farm, decommissioned railcar unloading station, and north tank farm consisting of one (1) 50,000 gallon tank of acetic anhydride, one (1) 50,000 gallon tank of acetic acid, one (1) 30,000 gallon tank of trieth, leene glycol, one 1) 30,000 gallon tank of spent glycol, one (1) 10,000 gallon tank of ethyleneglycol. ■ Outfall SWO03 SOTH (South): Drainage area consists of scrap metal dumpsters, hazardous waste storage, fuel oil tank storage, solid waste dumpsters,potable water for processes, propane refueling, a#6 closed in place AST, a gasoline and diesel unloading/loading station, hazardous and non-hazardous storage (sodium hydroxide 300 and corrosion inhibitor for the process water tank), an abandoned cooling tower tank farm, , 50,000 gallon tank facet;,. aeid, e ( ) 30,000 gallon tank ftFiethyle„e gi,,eo > > glyeol, and a waste holding pad. ■ DEMLR response: Based on updated information provided on the draft permit, the outfall descriptions have been updated. o Update North outfall ID as follows in Table 2 title and outfall description to be consistent with Permit Summary information: ■ North outfall ID changed from"SW002"to "NRTH" ■ DEMLR response: Outfalls must be assigned a numeric value in order for NC DEQ to transfer monitoring data from the state's database to the US EPA's database. The outfall denotation provided by the permittee is still included in the permit to ensure clarity in reporting monitoring data for the correct outfall. Page 8 of 10 o Add the following footnote to the Non-polar oil & grease monitoring line item to clarify that monitoring is only required in vehicle or equipment maintenance areas with>55 gallons/month of oil: "Monitoring for Non-Polar Oil & Grease is only required in vehicle or equipment maintenance areas in which more than 55 gallons of new motor oil and/or hydraulic oil per month is used when averaged over the calendar year." ■ DEMLR response: Monitoring for non-polar oil and grease is no longer required in only vehicle maintenance areas. This is a programmatic update. If more than 55 gallons (averaged) of oil are used per month, whether it's used for vehicle maintenance, equipment maintenance, or other usage, monitoring is required. o Update outfall description under Table 2 (page 15) as follows: ■ Outfall SWO02 NRTH (North): Drainage area consists of industrial waste dumpsters, covered storage area, cardboard recycling,and covered scrap metal recycling, brown and root scrap yard, oil and chemical storage, emergency firewater basin, HOA secondary containment basin, a cooling tower, and two (2) 5,000 gallons storage tanks of Therminol 66. • Note: See below regarding the requested addition of"covered" for scrap metal recycling in the above bullet. ■ DEMLR response: Celanese is welcome to request a permit modification in the future at such a time site conditions are changed. A site inspection by DEMLR regional office staff will be required to confirm any changes made to the site that will affect monitoring requirements. Until such a site change is made, monitoring for metals and hardness will remain in the permit. o Hardness and metals sampling requirement: ■ The metals (Total Copper, Total Lead, Total Zinc) and hardness benchmarks were added to the North Outfall (SW002 or NRTH) due to the storage of scrap metal. The scrap metal storage is contained in a dumpster at location#4 on the current site map, which is currently uncovered. ■ Celanese proposes adding a cover to the scrap metal storage dumpster such that the storage area is no longer exposed to stormwater and removing metals (copper, lead, zinc) and hardness sampling requirements from Table 2 in the draft permit. ■ DEMLR response: Celanese is welcome to request a permit modification in the future at such a time site conditions are changed. A site inspection by DEMLR regional office staff will be required to confirm any changes made to the site that will affect monitoring requirements. Until such a site change is made, monitoring for metals and hardness will remain in the permit. o The area at the North Outfall location is currently under construction under an approved Erosion and Sediment Control Plan. Following completion of the construction, the location of the north outfall is expected to be moved slightly from the current designated location. The new outfall location will be selected to ensure the location will still capture the full north drainage area as required and is not expected to change potential pollutants in the North Outfall runoff. The construction is expected to be completed in the spring of 2024. ■ Celanese will notify NC DEQ within 14 days of establishing the new outfall location, as required under Condition D-2. Until that time, Celanese will continue to follow the Erosion and Sediment Control Plan. ■ If the current construction is not completed prior to the next required sampling event, Celanese is seeking clarification regarding whether the quarterly benchmark sampling is expected be completed under permit NCS000064. Page 9 of 10 ■ DEMLR response: In the event of a discharge, a sample is required to be collected regardless of where the outfall is located. o If the newly issued permit is effective prior to the start of the second quarter(April 1, 2024), Celanese is seeking clarification on the timing for the first quarterly sample under the newly issued permit, if the expectation will be that a sample will be required to be completed during the 1 st quarter of 2024, with a shortened timeframe within which to complete the sampling. ■ DEMLR response: Per Part E-1. of the permit, "For permits issued between March 1-31, June 1-30, September 1-30 or December 1-31, sampling shall not commence until the next sampling period following initial issuance of the permit."

Eric Johnson and Randy Turner from CNA Holdings were present for the inspection. Facility records were not well organized. The version of the SWPPP provided during the inspection had not been reviewed within the last year. After the inspection, Mr. Johnson provided a more recent version of the plan that had been reviewed within the last year. Likewise, training records were not available on site, but were provided shortly after the inspection by email. The facility is conducting analytical monitoring and qualitative monitoring. However, better follow up is needed for potential issues identified in the qualitative monitoring. Records indicating a light odor and indicating poor clarity were present in the qualitative monitoring, without documented follow up actions. When a potential issue is identified via qualitative monitoring, follow up actions should be well documented and should be maintained with the SWPPP. The stormwater outfalls were observed during the inspection and no issues were identified. Construction was occuring near one outfall under an approved Erosion and Sediment Control Plan.

Brianna— I have worked with Celanese to review the draft permit. We are submitting the following comments on the draft permit following our review. Please let me know if we need to discuss any of these items further. 1. Requested text corrections: o Page 14: ■ Update outfall IDs as follows in Table 1 title and outfall description to be consistent with Permit Summary information: • East outfall ID changed from "SW001"to "EAST" • South outfall ID changed from "SW003"to "SOTH" ■ Add the following footnote to the Non-polar oil &grease monitoring line item to clarify that monitoring is only required in vehicle or equipment maintenance areas with >55 gallons/month of oil: • Monitoring for Non-Polar Oil & Grease is only required in vehicle or equipment maintenance areas in which more than 55 gallons of new motor oil and/or hydraulic oil per month is used when averaged over the calendar year. ■ Update outfall descriptions under Table 1 (Page 14) as follows,with added text in bold underline and removed text in strikethrough below: • Outfall SW001 EAST (East): Drainage area consists of loading and unloading activities, Marley cooling tower, 300 gallons of caustic, 120 gallons of boiler treatment, 120 gallons of oxygen scavenger, 120 gallons of corrosion inhibitor, 120 gallon of bromine, 120 gallons of biocide, and 120 gallons of cooling tower treatment, decommissioned tank 3 farm and unloading station, decommissioned south tank farm, decommissioned railcar unloading station, and north tank farm consisting of one(1) 50,000 gallon tank of acetic anhydride, one (1) 50,000 gallon tank of acetic acid,one(1)30,000 gallon tank of triethylene glycol,one (1) 30,000 gallon tank of spent glycol,one(1) 10,000 gallon tank of ethylene glycol. • Outfall SWQQ3 SOTH (South): Drainage area consists of scrap metal dumpsters, hazardous waste storage, fuel oil tank storage, solid waste dumpsters, potable water for processes, propane refueling, a#6 closed in place AST, a gasoline and diesel unloading/loading station, hazardous and non-hazardous storage (sodium hydroxide 300 and corrosion inhibitor for the process water tank), an abandoned cooling tower tank farm,ene (1) 58;000gallen tank ef aee#s-aRhYdFide e ( ) 50,000.ghee tank f speRt .,l. cel ene ( ) 10,000 nnn gaII9R tank f ethylene l.,ee and a waste holding pad. o Page 15: ■ Update North outfall ID as follows in Table 2 title and outfall description to be consistent with Permit Summary information: • North outfall ID changed from "SW002"to "NRTH" ■ Add the following footnote to the Non-polar oil &grease monitoring line item to clarify that monitoring is only required in vehicle or equipment maintenance areas with >55 gallons/month of oil: • Monitoring for Non-Polar Oil & Grease is only required in vehicle or equipment maintenance areas in which more than 55 gallons of new motor oil and/or hydraulic oil per month is used when averaged over the calendar year. ■ Update outfall description under Table 2 (page 15) as follows: • Outfall SWQQ2 NRTH (North): Drainage area consists of industrial waste dumpsters, covered storage area, cardboard recycling,a-n4 covered scrap metal recycling, brown and root scrap yard, oil and chemical storage, emergency firewater basin, HOA secondary containment basin, a cooling tower, and two (2) 5,000 gallons storage tanks of Therminol 66. o Note: see Item#2 below regarding the requested addition of"covered"for scrap metal recycling in the above bullet. 2. Hardness and metals sampling requirement: o The metals (Total Copper,Total Lead,Total Zinc) and hardness benchmarks were added to the North Outfall (SW002 or NRTH) due to the storage of scrap metal.The scrap metal storage is contained in a dumpster at location #4 on the current site map, which is currently uncovered. o Celanese proposes adding a cover to the scrap metal storage dumpster such that the storage area is no longer exposed to stormwater and removing metals (copper, lead, zinc) and hardness sampling requirements from Table 2 in the draft permit. Also, Celanese is seeking clarification on the following: 3. The area at the North Outfall location is currently under construction under an approved Erosion and Sediment Control Plan. Following completion of the construction,the location of the north outfall is expected to be moved slightly from the current designated location.The new outfall location will be selected to ensure the location will still capture the full north drainage area as required and is not expected to change potential pollutants in the North Outfall runoff.The construction is expected to be completed in the spring of 2024. o Celanese will notify NC DEQ within 14 days of establishing the new outfall location, as required under Condition D-2. Until that time, Celanese will continue to follow the Erosion and Sediment Control Plan. 4 o If the current construction is not completed prior to the next required sampling event, Celanese is seeking clarification regarding whether the quarterly benchmark sampling is expected be completed under permit NCS000064. 4. If the newly issued permit is effective prior to the start of the second quarter(April 1, 2024), Celanese is seeking clarification on the timing for the first quarterly sample under the newly issued permit, if the expectation will be that a sample will be required to be completed during the Vt quarter of 2024,with a shortened timeframe within which to complete the sampling. Also, next week is Eric Johnson's last week with Celanese so please continue to keep myself and Larry Wolnick copied on all communications.
