Box 249 Laurinburg NC 283530249 SUBJECT: April 14, 2014 Compliance Evaluation Inspection City of Laurinburg Leith Creek WWTP Permit No: NC0020656 Scotland County Dear Mr. Ellis: John E. Skvarla, III Secretary Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted on April 15, 2014. The Compliance Evaluation Inspection was conducted by Mark Brantley, Environmental Senior Specialist, of the Fayetteville Regional Office. The facility was found to be in Compliance with permit NC0020656. As a reminder, preservation of the Waters of the State can only be achieved through consistent NPDES Permit compliance. Comments • Facility was clean and neat in appearance at the time of the inspection. • Log books and maintenance logs were maintained. • In anticipation of the new industry, FCC, the Division of Water Resources encourages the town to prepare for the additional wastewater flow. Currently the WWTP is permitted for 4 MGD and operated at 58% capacity during 2013. Some of the projected flow rates from FCC have been up to 2MGD and this would put the Leith Creek WWTP at 100% capacity. Please review the Division of Water Resources rule (attached below) on wastewater treatment capacities and make plans as required. 15A NCAC 02T .0118 DEMONSTRATION OF FUTURE WASTEWATER TREATMENT CAPACITIES In order to insure that treatment, utilization, or disposal systems do not exceed their hydraulic treatment capacities, no permits for sewer line extensions shall be issued to wastewater treatment systems owned or operated by municipalities, counties, sanitary districts or public utilities unless they meet the following requirements: (1) Prior to exceeding 80 percent of the wastewater. treatment system's permitted hydraulic capacity (based on the average flow of the last calendar year), the permittee must submit an approvable engineering evaluation of their future wastewater treatment, utilization, and disposal needs. This evaluation must outline specific plans for meeting future wastewater treatment, utilization, or disposal Fayetteville Regional Office 225 Green Street, Suite 714, Fayetteville, North Carolina 28301-5095 Main Phone: 910-433-3300' 1 Internet: http://www.ncdenr.gov . An Eaual Opportunity \ Affirmative Action Emolover — Made in Dart by Recycled Paoer needs by either expansion of the existing system, elimination or reduction of extraneous flows, or water conservation and must include the source(s) of funding for the improvements. If expansion is not proposed or is proposed for a later date, a detailed justification must be made to the satisfaction of the Director that wastewater treatment needs will be met based on past growth records and future growth projections and, as appropriate, shall include conservation plans or other specific measures to achieve waste flow reductions. (2) Prior to exceeding 90 percent of the wastewater treatment, utilization, or disposal systems permitted hydraulic capacity, (based on the last calendar year), the permittee must obtain all permits needed for the expansion of the wastewater treatment, utilization, or disposal system and, if construction is needed, submit approvable final plans and specifications for expansion including a construction schedule. If expansion is not proposed or is proposed for a later date, a detailed justification must be made to the satisfaction of the Director that wastewater treatment needs will be met based on past growth records and future growth projections and, as appropriate, shall include conservation plans or other specific measures to achieve waste flow reductions. (3) The Director shall allow permits to be issued to facilities that are exceeding the 80 percent or 90 percent loading rates if the additional flow is not projected to result in the facility exceeding its permitted hydraulic capacity, the facility is in compliance with all other permit limitations and requirements, and it is demonstrated to the satisfaction of the Director that adequate progress is being made in developing the needed engineering evaluations or plans and specifications. In determining the adequacy of the progress, the Director shall consider the projected flows, the complexity and scope of the work to be completed and any projected environmental impacts.
