You must also complete the "Request For Remission, Waiver of Right to an Administrative Hearing, and Stipulation of Facts" form to request remission of this civil penalty. You should attach any documents that you believe support your request and are necessary for the Director to consider in evaluating your request for remission. Please be aware that a request for remission is limited to consideration of the five factors listed below as they may relate to the reasonableness of the amount of the civil penalty assessed. Requesting remission is not the proper procedure for contesting whether the violation(s) occurred or the accuracy of any of the factual statements contained in the civil penalty assessment document. Pursuant to N.C.G.S. § 14313-282. 1 (c), remission of a civil penalty may be granted only when one or more of the following five factors apply. Please check each factor that you believe applies to your case and provide a detailed explanation, including copies of supporting documents, as to why the factor applies (attach additional pages as needed). (a) one or more of the civil penalty assessment factors in N.C.G.S. 14313-282.1(b) were wrongfully applied to the detriment of the petitioner (the assessment factors are listed in the civil penalty assessment document); (b) the violator promptly abated continuing environmental damage resulting from the violation (i.e., explain the steps that you took to correct the violation and prevent future occurrences); (c) the violation was inadvertent or a result of an accident (i.e., explain why the violation was unavoidable or something you could not prevent or prepare for); (d) the violator had not been assessed civil penalties for any previous violations; (e) payment of the civil penalty will prevent payment for the remaining necessary remedial actions (i.e., explain how payment ofthe civil penalty will prevent you from performing the activities necessary to achieve compliance).

This letter serves as a written request for remission or mitigation of the Civil Penalty in the amount of $4,683.03 assessed to the City of Lincolnton WWTP. The City of Lincolnton has prepared this detailed statement that establishes why we believe the civil penalty should be remitted. We believe the following two of the five factors should be considered as outlined in the Notice of Violation letter under Option 2: Factor (2) whether the violator promptly abated continuing environmental damage resulting from the violation; and Factor (3) whether the violation was inadvertent or a result of an accident. The following is a brief narrative of the single event that led to the weekly and monthly Total Suspended Solids violations. The City of Lincolnton and surrounding areas received a 3.5 inch rainfall event that inundated our Wastewater Treatment Plant with a massive amount of Infiltration & Inflow. The rain event started on December 15, 2022 and lasted through December 16, 2022. We sustained a flow rate of 11 million gallons per day (MGD) for a period lasting approximately 4 hours and a period CITY OF LINCOLNTON WASTEWATER TREATMENT PLANT 550 W. HWY. 150 BYPASS • P.O. BOX 617 • LINCOLNTON, NORTH CAROLINA 28093-0617 PHONE (704) 736-8960 FAX (704) 732-6137 above 6 MGD for several hours before and after the 11 MGD event. Our Wastewater Treatment Plant is designed for 6 MGD of flow with all treatment units in proper working order. However, we currently have 1 of our 2 final clarifiers out of service, as noted in our annual plant inspection. With this amount of flow coming into our plant and with only 1 final clarifier in service, we experienced a solids washout from our clarifier. We tried cutting our blowers off that supply air to our aeration basin in hopes of keeping the solids from overloading our final clarifier, but the duration of the high flow rate pushed solids from the aeration basin into the clarifier. The flow rate coming into our 1 clarifier was to great for the solids to settle out and thus, the solids washed over our weirs and into our plant effluent. These washed out solids were captured by our effluent sampler, and thus caused us to have a daily Total Suspended Solids of 843 mg/I for December 16, 2022. This was the only day we recorded a significantly high Total Suspended Solids and should prove that we promptly abated the solids washout a soon as our flow rates returned to normal levels as outlined in Factor 2 above. The only other operational strategy we could have employed would have been to cut off 2 of our main lift station influent pumps and let the flow stabilize to our Wastewater Treatment Plant at around 5 MGD. However, we would have caused several sanitary sewer overflows (SSO's) within our collection system. We chose not to implement that strategy, as the SSO's would have had a far greater environmental impact than the 1 day Total Suspended Solids violation. We think we made the right decision in a situation that was, without doubt, beyond our control and an Act of God. We would have been compliant for the month of December 2022 had it not been for that one, single day TSS violation. That one day, one event caused us to exceed not only our weekly TSS average, but our monthly average. For example, removing December 16ths 843 mg/I daily result would have led us to have a weekly average of 9.6 mg/I for that week and a monthly average of 18.7 mg/I for December 2022. As I stated above, I could have chose to stabilize the flow to our plant and we would not have sustained a TSS violation. However, I chose to treat as much wastewater as possible and not cause even greater environmental harm by causing multiple SSO's. Choosing the lesser, however, did create this one day, one time Total Suspended Solids violation that was great enough to cause not only a weekly TSS violation, but a monthly TSS violation as well.

BOX 617 - LINCOLNTON, NORTH CAROLINA 28093-0617 PHONE (704) 736-8960 FAX (704) 732-6137 believe a Civil Penalty in the amount of $3,375.00 for Exceeding our Weekly Average and a $1,125.00 fine for Exceeding our Monthly Average is very excessive considering the fact that a one day rain event caused these violations to occur. This event was well beyond our control and we believe the decision to treat as much incoming wastewater as possible was the correct decision to make given the circumstance we were facing. It is our hope that the Wastewater Branch of the Division of Water Resources will consider the information provided above in our request for remission or mitigation of the Assessment of Civil Penalty issued to the City of Lincolnton, Case No. LV-2023-0089. We also hope that the Wastewater Division heavily considers the fact that a heavy rain event caused a one -day extremely high Total Suspended Solids result, which caused the said violations. Without this one -day rain event occurrence, the City of Lincolnton would have been 100% compliant with our NPDES Permit for the month December 2022. Thank you in advance for your consideration of this request. Best regards, Donald A. Burkey, Jr. WWTP Superintendent City of Lincolnton Post Office Box 617 550 W.
