Please review this draft carefully to ensure your thorough understanding of the information, conditions, and requirements it contains. The first draft permit included the following significant changes from the existing permit: 1. Section A. (3)has been updated concerning electronic submission of effluent data. Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). 2. Outfall map has been updated. 3. The address of the facility has been updated on the cover sheet and Supplement to Permit Cover Sheet based on the renewal application. 4. Language has been updated on the Supplement to Permit Cover Sheet per the renewal application and the current water treatment plant strategy. 5. The flow measurement frequency has been changed to continuous and the sample type has been changed to recording in Section A. (1)per the current water treatment plant strategy. 6. Instream monitoring for turbidity has been removed in Section A. (1) as instream turbidity monitoring is not required by the current water treatment plant strategy. 111:-"IrCT) WNrks�sl d�[ex�ars�.a�s� North Carolina Department of Environmental Quality I Division of Water Resources 512 North Salisbury Street 11617 Mail Service Center I Raleigh,North Carolina 27699-1617 919.707 9000 Mr. Rich Hester Draft NPDES Permit NC0084735 7. Monitoring for Total Aluminum have been removed in Section A. (1) as the permit renewal application indicated alum/aluminum sulfate does not have the potential to be discharged. , 8. Monitoring for Total Manganese has been reduced to quarterly in Section A. (1)per the current water treatment plant strategy. 9. Monitoring for Total Fluoride has been reduced to quarterly and the limits removed in Section A. (1)based on a reasonable potential analysis. 10. Since the facility performs Ion Exchange treatment,monitoring has been added for salinity, conductivity, and dissolved oxygen per the current water treatment plant strategy. 11. Sampling has been changed to composite for Total Dissolved Solids,Total Suspended Solids, Total Iron,Total Manganese, Total Zinc, Chlorides, Ammonia Nitrogen, Total Nitrogen, Total Phosphorus, and WET monitoring per the current water treatment plant strategy. 12. Monitoring for total dissolved solids has been increased to 2/Month per the current water treatment plant strategy. 13. Monitoring for turbidity has been decreased to 2/Month per the current water treatment plant strategy 14. Effluent and upstream monitoring for Total Hardness and associated footnotes have been added in Section A. (1)per the current water treatment plant guidance. 15. Former footnote#3 has been removed in Section A. (1) as monitoring for Total Zinc is required due to the potential to be discharged. 16. Former footnote#4 has been removed in Section A. (1) as monitoring for Ammonia Nitrogen is required due to the potential to be discharged. 17. Former footnote#5 has been removed in Section A. (1) as monitoring parameters in conjunction with toxicity testing is no longer required. 18. Former footnote#6 has been removed in Section A. (1) as instream turbidity monitoring is not required, and any other parameters requiring instream monitoring would need the Division's approval to use monitoring coalition data. 19. Footnote regarding WET testing in Section A. (1)has been updated. 20. Former Section A. (2) "Permit Reopener: Whole Effluent Toxicity Monitoring"has been removed as the facility has passed the last 12 toxicity tests. 21. Toxicity language and the IWC in Section A. (2)have been updated. The second draft permit includes the following significant changes from the first draft permit: 1. The Supplement to Permit Cover Sheet has been updated to indicate ion exchange treatment is used but is discharged to the Johnston County Wastewater Collection System. 2. The Supplement to Permit Cover Sheet has been updated to include a future expansion of potable water to 14.0 MGD while reflecting the designed maximum discharge potential will remain at 4.0 MGD. 3. As the facility discharges the ion exchange wastewater to the sewer system,monitoring has been removed in Section A. (1) for salinity, conductivity, and dissolved oxygen per the current conventional water treatment plant strategy. 4. Monitoring has been added back for Total Copper in Section A. (1) as it was mistakenly removed in the previous draft permit. Mr. Rich Hester Draft NPDES Permit NC0084735 5. As the facility discharges the ion exchange wastewater to the sewer system, sampling has been changed in Section A. (1) from composite to grab for Total Dissolved Solids, Total Suspended Solids, Total Iron, Total Manganese,Total Zinc, Chlorides,Ammonia Nitrogen, Total Nitrogen, Total Phosphorus,total hardness, and WET monitoring per the current conventional water treatment plant strategy. Thank you for submitting comments on the first draft permit. Please note that upstream total hardness monitoring will remain in the permit as this is required for discharges into freshwater per the current water treatment plant guidance. Increased monitoring for total dissolved solids will remain as this is based on the volume of effluent discharged from the facility per the current water treatment plant strategy. Monitoring for salinity, conductivity, and dissolved oxygen have been removed from the draft permit per the current water treatment plant strategy for conventional treatment technology as the ion exchange wastewater does not have the possibility to be discharged to the Neuse River. Composite sampling for total dissolved solids, total suspended solids, chlorides,total iron,total manganese,total zinc, ammonia nitrogen,total nitrogen,total phosphorus, and WET monitoring has been changed to grab sampling per the current water treatment plant strategy for conventional treatment technology as the ion exchange wastewater does not have the possibility to be discharged to the Neuse River. It is the Division's understanding that Johnston County is in the process of requesting a 2.0 MGD expansion from the Department of Environmental Quality's Public Water Supply program, which is projected to increase the volume of wastewater discharged. As communicated by Johnston County,this expansion will not cause the wastewater discharge to exceed the current design discharge flowrate of 4.0 MGD at the Johnston County WTP. If wastewater discharge volumes are expected to exceed the current design capacity, a permit modification must be requested. After review,the facility will remain classified as Grade II Physical Chemical Water Pollution Control System as the classification is based on the treatment process, and the Johnston County WTP utilizes both conventional and ion exchange treatment. If you have further concerns about the ORC certification,please contact the NC Operators Certification Program directly. With this notification, the Division will solicit public comment on this draft permit by publishing a notice in newspapers having circulation in the general Johnston 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].
