G., Assistant Regional Supervisor Water Quality Regional Operations Section Mooresville Regional Office Division of Water Resources, NCDEQ Subject: Notice of Violation and Intent to Assess Civil Penalty Tracking Number: NOV-2023-LV-0252 Permit No. NC0071528 Lake Norman Woods WWTP Catawba County Mr. Pitner, Thank you for allowing the Lake Norman Woods HOA the opportunity to respond to the Notice of Violation dated March 16, 2023; received April 19, 2023. This response pertains to the (3) BOD daily maximum exceedances, (1) Ammonia Nitrogen average exceedance, and subsequent monthly average exceedances for both parameters that occurred during the February 2023 monitoring period. These exceedances were caused by various complications with plant infrastructure, which are currently being addressed through ongoing reconstruction efforts. The factors described below adversely affected the plant's operations at the time that these violations occurred. During February, the sludge returns were temporarily down. Ongoing complications with the blowers resulted in challenges in the plant receiving enough air, which impacted the biological life in the plant and affected the treatment process. In the interim, operators have conducted manipulation of the blowers on an as -needed basis to ensure that they are operating adequately while the plant continues to undergo rehabilitation. Within the next two weeks, new pulleys are being installed on the blowers, and there are plans to install new air lines within the next 30 days. It is always the goal of the Lake Norman Woods HOA to remain in compliance with regulations set forth by the Division of Water Resources. It is our request that our cooperation and action in these matters be taken into account by the Division when proceeding with enforcement. Sincerely, Z�)aA // Zt l)&t'YL0_.
