Please be advised that in accordance with your current NPDES Permit #NC0024244, Part II, Section B (10.) Expiration of Permit; The Permittee is not authorized to discharge after the expiration date. In order to receive automatic authorization to discharge beyond the expiration date, the Permittee shall submit such information, forms, and fees as are required by the agency authorized to issue permits no later than 180 days prior to the expiration date unless permission for a later date has been granted by the Director. Flows for the calendar year 2020 were caculated with a yearly average flow of 6.247 MGD or 52.05% of the 12 MGD permitted flow. Compliance history for the period August 2020 through July 2021 was reviewed with the following reported violations: 11/2020 TSS Monthly Average Limit Violation 26.5% Over Permit Limit 11/2020 TSS Weekly Average Limit Violation 4% " 11/2020 TSS Weekly Average Limit Violation 32.8% ,, 10/2020 TSS Weekly Average Limit Violation 9.6% " 09/2020 TSS Monthly Average Limit Violation 79.2% ,, 09/2020 TSS Weekly Average Limit Violation 30.7% " 09/2020 TSS Weekly Average Limit Violation 12.9% 09/2020 TSS Weekly Average Limit Violation 33.3% 04/2021 Total Ammonia as Nitrogen Limit Violation 5.1% " Annual report for fiscal year 2020/2021 has not been prepaired. Please note that Annual reports must be submitted within 60 days of the end of the applicable 12-month review period. Customers and users are to be provided access to the report. The subject facility is under Special Order by Consent (EMC SOC WQ S19-007) with modified permit parameters for BOD (Summer/Winter), Ammonia Nitrogen (Summer/Winter), and TSS. Please note that in accordance with your SOC (SOC WQ S19-007) Item 2. (d), No later than fifteen (15) calendar days after any date identified for accomplishment of any activity listed in 2(a) above, table of Scheduled Activity, the City shall submit to the Water Quality Regional Operations Section Regional Supervisor written notice of compliance or noncompliance therewith. Please also note that quarterly progress reports detailing the work and activities undertaken and completed on the upgrades to the collection sustem are to be submitted. At time of inspection records and required information appeared to be well kept and readily available for review. At time of insepction it was noted that effluent was turbid. Effluent passes through 10 micron filters before being discharged. The Highway 52 Water Treatment Plant (WTP) reported discharging 313,000 gallons of filter backwash water to Long Creek WWTP the day of inspection. Alum sludge from the WTP is also reported being disposed of by discharging to the WWTP. The Long Creek WWTP reported TSS violations on 11/2020, 10/2020, 09/2020 and 4/2021. Violations under SOC have been addressed with stipulated penalty SP-2020-0010 and SP-2021-0001. The discharge of Alum Sludge into the sewer collection system is adversely affecting effluent discharge into Long Creek by introducing turbidity (Total Suspended Soilds) into receiving waters. Please be advised that in accordance with the Highway 52 Water Tereatment Plant NPDES Permit #0044024, Part II, Section B, 2. Duty to Mitigate, the Permittee shall take all reasonable steps to minimize, to prevent any discharge, or sludge use, or disposal in violation of this permit with a Page# 2 Permit: NC0024244 Inspection Date: 08/25/2021 Owner - Facility: Long Creek WWTP Inspection Type: Compliance Evaluation reasonable likelihood of adversely affecting human health or the environment.

Removal Substances, Solids, sludge, filter backwash, or other pollutants removed in the course of treatment or control of wastewaters shall be utilized/disposed of in accordance with NCGS 143.215.1 and in a manner such as to prevent any pollutant from such materials from entering waters of the State or navigable waters of the United States. It is therefore required that the City of Albemarle submit a written plan for alternative disposal of alum sludge from Highway 52 Water Treatment Plant to the Mooresville Regional Ofice. A written response is to be sent within 30 days of receipt of inspection report.
