We wish to install a Phinite Sludge Drying System to manage sludge on this farm. Details and siting information are attached. Approval is requested under Section 1-10 of the North Carolina Swine Farm General Permit. DocuSigned by: ja ln, 1;t d t, BC353E9CE264487... Warm regards, John Bode Owner DocuSign Envelope ID: D6EAF59F-4A48-4686-947D-6D3D0DO1E84D Project description — NC DEQ Permit Modification Overview: The Phinite Sludge Drying System will be located on the farm and acts to dry anaerobically digested hog manure residuals (sludge) that have accumulated in the lagoon over time. Sludge material is removed from the lagoon and loaded into the drying shed. The material harvested from the lagoon is a solid/semi-solid material and has little to no free water. Sludge extraction has no deleterious effect upon lagoon operation, and improves lagoon function by increasing the volume of the anaerobic treatment zone over time. Over a period of typically 2 months, the material dries through the use of ambient airflow. A robot mechanical agitator is located inside the structure and is operated by Phinite to mix the material and assist it in drying. Dried sludge material will stored on -site until it can be utilized as a soil amendment by transfer to a certified manure hauler. Sludge drying and exporting projects have the potential to improve the environmental quality of North Carolina by a substantial amount, through the redistribution of manure nutrients to areas of nutrient deficit. Project Specifics: This drying project has been sized to service 5,000 finishing spaces. The drying system consists of a concrete basin 190ft long and 30ft wide with 2ft high sidewalls. The concrete floor slopes toward a sump which is designed to catch any water. Any water captured by the system is contained within a water -containing structure and is returned to the lagoon. The drying system is covered by a hoop greenhouse which keeps out rainfall. Side curtains are used to allow airflow into the building and are lowered during rain events. The concrete slab is a minimum of 4" thick and is constructed to appropriate engineering standards. The concrete side walls are constructed on -top of the slab with appropriate tie-ins. This water - containing structure is designed to contain and prevent migration of any pollutants handled by the drying system. All liquid is captured and returned to the lagoon on the farm. Although there is no specific structure within the NC siting act that is consistent with a Phinite Drying System, Phinite confirms the proposed location complies with requirements of the NC siting act. See the attached drawings for review of locations with respect to the NC Siting Act. The Waste Utilization Plan at this site has been reviewed by a Technical Specialist. This project is not located within an existing sprayfield. As a result the site Waste Utilization Plan does not need to be updated. Reporting: This project will keep records of: • The date and volume of sludge removed from the lagoon during each sludge extraction event. • The volume of dry product transported off the farm. • The destination of each batch of dry product extracted from the lagoon. These records will be updated to the farm waste logs every 3 months. Sludge removal will be correlated with sludge surveys performed each year under the normal operations on the farm. 1 DocuSign Envelope ID: D6EAF59F-4A48-4686-947D-6D3D0DO1E84D NC STATE Calm Winds (<0.9 m/s): 43.6% of observations Wind Speed: • 0.9to2ms 2 to 3 ms Wind rose for KCTZ in Clinton, NC For Jan 6, 2002 to Aug 9, 2022 (94% of data available) N NNW WNW W Wsw 3 to 5 ms 5 to 7 ms NNE • 7to9ms • ?9ms NE SE ENE E ESE Figure 1 - Windrose for Clinton - the most relevant wind monitoring location for this site.
