General Information 0 Facility/System Name: Jacksonville Land Treatment Facility RECEIVED Responsible Entity: City of Jacksonville MAR PO Box 128 5 2024 Jacksonville, NC 28541-0128 NCDEQ/DWR/NPDES In Charge Contact: Brandon D. Davis, Plant Superintendent Thomas Johnson Jr., Utilities Maintenance Superintendent Applicable Permits: Non-Discharge Permit No. WQ0009267 Collection System Permit No. WQCS00268 The City of Jacksonville's wastewater collection system is composed of approximately 300 miles of sanitary sewer lines and 48 wastewater pumping stations. Twenty-six of these pumping stations have on-site generators to provide power in the event of power failures and the remaining stations have standby connections, which allow them to be powered by portable generators during power outages. In addition, 37 of the pumping stations also have bypass connections that allow the use of portable bypass pumps that will redirect water flow if a power outage occurs. The City currently owns 5 portable generators and 3 portable bypass pumps. The City's Utilities Maintenance Division staff consists of 29 employees and is responsible for maintenance, repair and the proper functioning of the sewage collection system and the maintenance and efficient operation of the wastewater pumping stations. This Division provides routine inspections of the City's manholes and is responsible for jetting sewer lines to clear blockages. This staff also provides preventive maintenance to all the wastewater pumping stations and generators to ensure optimum operation. A section within the Division is responsible for ensuring all privately owned grease traps are maintained within the City ordinance requirements. The Utilities Maintenance Division also has an Inflow&Infiltration (I&I) Analyst on staff to identify, document, and reduce inflow and infiltration into the City's collection system. The Jacksonville Land Treatment Site (LTS) totals 7,400 acres of land and is responsible for the treatment and land application of the City's wastewater. The system is presently designed to treat 9.0 million gallons of wastewater daily via spray irrigation of 2,300 acres of primarily loblolly pine trees. Wastewater is transported 8 miles from Jacksonville to the LTS by a 36-inch diameter force main. The wastewater is treated with hydrogen peroxide for odor removal prior to flowing into the headworks facility. At the headworks facility, the influent (raw wastewater) passes through dual Huber Step Screens where material greater than 1/8 inch in size is removed. The wastewater then flows into an aerated grit and grease removal system where inorganic material and floating materials are removed. From there, wastewater flows into a series of aerated lagoons where biological treatment of the waste occurs. Secondary treated wastewater then flows into storage lagoons where it is held for irrigation. The storage lagoons have a capacity of 690 million gallons and provide storage of treated wastewater during periods of inclement weather and when spray irrigation is not feasible. The treated wastewater is chlorinated to eliminate harmful bacteria and then used to irrigate 2,300 acres of pine forest on the LTS property. The irrigation fields have three classifications of soil types: Well-drained, Moderately Well-drained, and Seasonally Suitable. These irrigation fields are divided into 28 blocks and the annual hydraulic loading for each block is a permitted maximum ranging from 49.0 to 62.6 inches/acre, depending on the relative percentage of each soil type. City of Jacksonville 2023 Annual Performance Report As the pines mature and their ability to store nutrients decreases, the mature trees are harvested and used for pulp wood. Young seedlings are planted to repeat the cycle. The Land Treatment Facility is staffed by a Plant Superintendent, a Lead Operator, six Wastewater Plant Operators, three Plant Maintenance Mechanics, one Crew Leader, and four Equipment Operators. The Laboratory Section is also housed at the LTS and is staffed by the Supervising Chemist, assisted by two Chemists, who performs all the required analyses and is responsible for the certification of the wastewater laboratory. II. Facility Performance The City of Jacksonville's Land Treatment Facility treated 1,668 million gallons of wastewater during the 2023 calendar year, at an average daily flow of 4.6 million gallons. The City was in full compliance with all monitoring and reporting requirements during the 2023 calendar year. III. Collection System Performance There were six (6) reported overflows from the collection system during the 2023 calendar year. The locations with overflows were as follows: • May 14, 2023: 207 Linwood Drive approximately 110 gallons spilled due to debris in the line. • July 6, 2023: 1352 Lejeune Boulevard approximately 1,700 gallons spilled due to continuous heavy rainfall. • August 31, 2023: 2302 Onslow Drive approximately 3,000 gallons spilled due to Tropical Storm Idalia. • August 31, 2023: 411 Wooten Park Drive approximately 1,720 gallons spilled due to Tropical Storm Idalia. • December 27, 2023: 11 Dewitt Street approximately 500 gallons spilled due to continuous heavy rainfall. • December 27, 2023: 303 Southbridge Dr. approximately 700 gallons spilled due to continuous heavy rainfall. The City maintained constant communication with NCDWQ after each of these events to ensure full compliance with Environmental Laws and Regulations. The City continues to identify and remediate inflow and infiltration, as well as rehabilitate wastewater infrastructure to prevent further overflows. IV. Summary The City of Jacksonville's Land Treatment Facility and collection system performed excellently during the calendar year 2023. The total rainfall for 2023 was 62.1 inches at the Administration Building of the Land Treatment Facility and the total influent and effluent for 2023 was 1,668 million gallons and 1,441 million gallons, respectively. New sewer projects totaling 211 linear feet (LF) of 8-inch sewer pipe and 110 linear feet (LF) of 24-inch sewer pipe were added during 2023. The City has ongoing maintenance programs to ensure the wastewater collection system continues to function effectively. The City utilizes cured-in-place lining, point repairs, and manhole lining to reduce or eliminate inflow and infiltration. Other measures include the rain stopper program, fats, oils, and grease management, and pump station maintenance. The rain stopper program is a continuous effort to insert rain stoppers in manholes to prevent or minimize overflows when heavy rainfall occurs. The Fats, Oils, and Grease (F.O.G.) Management Program attempts to mitigate blockages and other issues through ordinances, grease interceptors, cleaning and maintenance, as well as education and awareness efforts. In Jacksonville, there are 252 establishments with grease interceptors that must be cleaned every 30 days. They are also regularly inspected to ensure compliance. In addition, the City cleaned 167,623 linear feet (LF) of sewer pipe in the collection system during 2023. Lastly, the City has a program that evaluates and replaces pumps in wastewater stations that fail or are over 20 years old. 2 I certify under penalty of law that this report is complete and accurate to the best of my knowledge.
