Revision: 2024 3 | P a g e Introduction Purpose The purpose of this document is to define the operation of the Ogden City Green Waste Composting Facility (“Facility”). It is the goal of Ogden City to conduct business in a manner that is environmentally sustainable, adds value to the community, and meets federal, state, and local laws. In Ogden City, there is a pressing need to divert biodegradable material from rapidly filling county landfills. This need has made a composting facility a priority for our community. This Facility accepts green waste (dry leaves, twigs, branches, grass clippings, fresh plant trimmings, etc.) from residents of Ogden City and processes these materials to produce compost, mulch, wood chips, rock chips, and firewood bundles for residents, commercial businesses, and government entities. The Facility also accepts a small amount of sludge from the Ogden Canyon Water Treatment Plant located in the Ogden Canyon. On-Site Lines of Authority The Facility is owned and operated by Ogden City Corporation (“Ogden City”). Daily operation of the Facility is under the direction of the Public Works Maintenance Supervisor. In the event the Maintenance Supervisor is absent, the on-site Equipment Operator oversees the Facility. Contact Information Name Title Phone Email Gina Arellano Public Works Maintenance Supervisor (801)629-8405 GinaArellano@ogdencity.com Caroline Kamoe Public Works Maintenance Crew Leader (801) 629-8318 CarolineKamoe@ogdencity.com JD Gladstone Public Works Equipment Operator (801) 629-8408 JasonGladstone@ogdencity.com General Facility Information The Facility is located at the address and legal description listed below. Appendix A includes maps, plans, and drawings of the Facility. Physical Address 1845 Monro Blvd, Ogden City, UT 84401 Legal Description The legal description for the Facility is attached to Appendix B. Ogden City is the owner of the property and proof of ownership is attached in Appendix B. There are no lease agreements for the Facility. Location Standards In accordance with R315-312-3, the Facility’s proximity to the following sensitive areas or site uses was assessed to confirm compliance. Appendix A includes a map showing the location standards buffer zone which indicates that the only building within the 500-foot buffer zone is an office building owned and operated by Ogden City. Also included in Appendix A are locations of the nearest sensitive areas as indicated in the table below. It can be seen that the Facility does not fall within any of the referenced sensitive areas. Ogden City Green Waste Composting Facility – Plan of Operations Last Revision: 2024 4 | P a g e Feature or Site Use Nearest to Facility Approximate Distance Wetland Utah Geological Survey identified 5.44-acre Freshwater Forested/Shrub Wetland 1000 feet Floodplain FEMA identified 100-year Zone AE floodplain 300 feet horizontal and 50 feet lower in elevation Watercourse Ogden River 300 feet horizontal and 50 feet vertical Market and Feasibility The Facility in Ogden City addresses a vital market need driven by residents' desire for sustainable waste management solutions. Residents are eager to find eco-friendly methods to dispose of their yard waste. This Facility not only meets these needs but also offers significant environmental benefits. By composting green waste, the Facility reduces the volume of waste sent to landfills, decreasing methane emissions, a potent greenhouse gas. The compost produced enriches soil, promotes healthier plant growth, and reduces the necessity for chemical fertilizers, which can pollute local waterways. Moreover, the facility supports broader sustainability initiatives by promoting a circular economy, where organic waste is transformed into valuable resources, thereby enhancing community resilience and environmental stewardship. Historical and archeological identification efforts Ogden City requested an assessment by the Utah State Historic Preservation Office of potential historical or archaeological impacts at the Facility as required by R315-310-3(1)(k). This request and the Utah State Historic Preservation Office’s response has been included in Appendix C. Appendix C also includes site photos and historic aerial imagery of the Facility. It was determined that this Facility's operation does not affect any known cultural resources. Compost Facility Services Area Served The composting facility accepts green waste from residents of Ogden City and processes these materials to produce mulch, wood chips, rock chips, and firewood bundles for residents, commercial businesses, and government entities both within and outside of Ogden City boundaries. Waste Types Accepted The Facility strictly accepts organic green waste from Ogden City residents with a Green Waste Pass. The green waste accepted at the facility includes bulk yard debris (dry leaves, twigs, branches, grass clippings, fresh plant trimmings, etc.). In addition to green waste, the Facility also accepts sludge from the Ogden Canyon Water Treatment Plant located on Ogden Canyon Road. This treatment facility is owned and operated by Ogden City and treats surface water from Wheeler Creek and Pineview Reservoir to drinking water standards during the summer months. The sludge produced is a byproduct from the drinking water treatment clarifiers. The Ogden City Water Production Supervisor in charge of the Treatment Plant sent a certification that the sludge produced at the Ogden Canyon Water Treatment Plant is non-hazardous and contains no PCB’s or treated wood. This certification is included in Appendix C as well as a sludge sample from the treatment process out for analysis in 2008 to Chemtech- Ford. There were no hazardous materials found in the sludge. The only detectible analyte found, was Barium (see attached sample report in Appendix C). The level of Barium found was very low (.75 ppm or mg/L). The Ogden City drinking water treatment plant sludge is dewatered though a belt press with a liquid capture rate of 95% - 99%. The final sludge product delivered to the compost facility is a moist dirt texture and contains no free liquids. Ogden City Green Waste Composting Facility – Plan of Operations Last Revision: 2024 5 | P a g e During plant operation, the Facility accepts approximately 2 dump truck loads of this sludge which is mixed with green waste to produce the final compost product. The sludge makes up no more than 8% of the final compost product. This Facility is identified during an emergency operation to accept windblown trees and other vegetation from surrounding cities. However, this is not a regular service provided by the Facility. The Facility does not accept nor utilize domestic sewage sludge, septage, or municipal solid waste. Facility Services The Facility services include: • Green Waste Management Services: Disposal facility for bulk yard debris (dry leaves, twigs, branches, grass clippings, fresh plant trimmings, etc.). For drop off by Ogden City residents only. • Products: Compost, mulch, wood chips, rock chips, and firewood bundles are generated from green waste described above for purchase by anybody. Compost produced at the Facility is quality tested on a quarterly basis, to analyze key elements like nitrogen, phosphorus, potassium, micronutrients, moisture, pH, and salinity. This helps determine optimal application rates to improve soil health and prevent nutrient imbalances or environmental issues. Run-on/Run-off Analysis The Facility is elevated in relation to surrounding areas such that no storm water runs on site. Storm water which falls onto the Facility is retained by a mulch berm that is approximately 6 feet tall has been placed around the perimeter of the Facility to retain storm water. Appendix A includes a Site Drainage plan which provides storm water calculations, site contours, details for the mulch berm, and shows where ponding occurs within the Facility. Utah Administrative Code R315-312- 3(4)(h)(ii) requires that the run-off systems for a compost facility are designed, installed, and maintained to control and collect the run-off from a 25-year storm event. It can be seen in the Site Drainage Plan that the Facility currently exceeds this requirement. Plan of Operation Waste Handling Procedure As mentioned above in the Compost Facility Services section, this Facility only accepts green waste and sludge from the Ogden City drinking water treatment plant. All material that is delivered to the Facility will be processed as follows: • All waste arriving at the Facility undergoes a preliminary visual inspection upon entry. Once the material is determined to be green waste or drinking water treatment sludge, the vehicle will be directed to the composting area via an access road directly north of the site entrance. • All vehicles containing clean loads of green waste will be directed to unload at the green waste unloading area termed the “branch pile” and/or the “grass pile”, depending on the type of green waste delivered • Any Ogden City vehicle delivering drinking water treatment sludge is directed to unload such material in a pile directly west of the grass pile. Ogden City Green Waste Composting Facility – Plan of Operations Last Revision: 2024 6 | P a g e • Green waste will be consolidated into the “branch pile” for holding until a 3rd party is contracted to grind the material using a tub grinder and track hoe. A third party is contracted to conduct grinding 2-3 times per year. • The green waste from the “branch pile” will be reduced in size (ground) by the tub grinder. Half of the branch pile is ground once (single ground), and the rest is ground twice (double ground). The windrow piles are then produced by mixing approximately 30% of materials from the “grass pile”, 30% of single ground “branch pile” materials, 30% of double ground “branch pile” materials, and approximately 8% of drinking water treatment sludge. • The windrow piles are then processed following the composting process described in the Composting Process section of this document until the compost process is completed and the produce is ready to be screened. • Ogen City then rents a trommel screener. The trommel screener will sort the material by size into one of three piles. The screening process starts with a 1.5” screen to remove all material larger than 1.5” diameter and termed “Overs”. This Overs material is then sent to the Landfills. Then a 3/8” screen is used on the remaining material to separate fines and medium particle sizes. “Fines” material is compost that is less than 3/8” in diameter and ready to purchase. “Mediums” material is between 1.5” and 3/8” and is sold as dark woodchips. Alternative Waste Handling or Disposal Typically, all waste accepted at the Facility is processed to produce sellable compost product. Excess product which is not sold can become a fire hazard. Therefore, unsold excess product is disposed of properly at the Landfills. Furthermore, as stated in the section above, large materials screened from the compost product are disposed of at the Landfills. Any materials not destined for processing shall be properly disposed of at the Landfills. Operational Training Plan The on-site Facility Equipment Operator oversees training for all new hires at the Facility. Newly hired employees undergo a rigorous training program that typically takes multiple months to ensure that new personnel are equipped with all resources and education needed to facilitate site operation. The Facility leadership has developed standard operating procedures (SOPs) where new employees are required to review and sign off that facility operational procedures are understood. These SOPs have been attached in Appendix D. Ongoing supervision of all personnel is necessary to ensure successful and safe Facility operation. All Facility employees are also trained annually in the identification of prohibited hazardous waste and prohibited waste containing PCBs and treated wood. See Appendix D for training documents and forms utilized by the Facility. Contingency Plans Fire and Explosion The greatest potential for fire exists in the stockpiles of unprocessed green waste. All stockpiles of unprocessed green waste will be kept at a minimum to lessen the potential impact of a fire. All processing equipment will be operated and stored at a safe distance from material stockpiles. Furthermore, there are multiple fire hoses kept on site and there is easy access to the site fire hydrant. During months of high temperatures, dry grass surrounding the Facility is trimmed and wetted to help mitigate potential fires. In prior operation of the Facility, windrows were placed with minimal to no drive isle between piles. However, this Ogden City Green Waste Composting Facility – Plan of Operations Last Revision: 2024 7 | P a g e practice has been changed to allow a drive isle between the cure pile and the separated windrows to provide access for fire trucks to reach the full extent of the Facility. Ogden City Fire Department is always called to the Facility if a fire occurs to ensure that the fire is eliminated. The primary means of fire control in the Facility is to isolate hot or burning solid waste. In the event of a fire at the Facility during operation hours, the burning material would be separated from the other materials and doused with water simultaneously. This action would be supported, when necessary, by the mobilization of additional equipment and personnel owned and operated by the city (e.g. Ogden City Fire Department). Corrective Action for Groundwater Contamination The possibility of ground water contamination from the composting operation is unlikely. If an impact to the ground water system is suspected, monitoring wells will be installed to collect data. If the data were to indicate that the composting operation is contaminating the groundwater the composting operation would be modified to improve protection of groundwater and a groundwater treatment plan would be developed and implemented. Failure of a Containment System The containment system at the Facility consists of a berm (approximately 6 feet in height) around nearly the full perimeter of the site (See Appendix A). This berm is designed to contain storm water, mitigate disruptive sounds, smells, and views, as well as act as a perimeter control to mitigate trespassing. Outside the berm perimeter is a densely vegetated and wooded hillside where contained storm water on site would be filtered through surface flow in the case of berm failure. In the event of a failure of the berm, on-site personnel should immediately notify all other on-site personnel and the Public Works Maintenance Supervisor and deploy temporary barriers to control the spread of run-off. The situation should be quickly assessed to determine the extent of the failure, and additional containment measures should be implemented if necessary. Authorities must be informed, and coordination with emergency responders should be established as needed. Cleanup operations should commence immediately, and the damaged system should be repaired as soon as possible to prevent future incidents. Detailed documentation of the incident and a review of the response should follow to improve future preparedness. Contingency Plans for Unpermitted Waste The Facility strictly accepts only green waste and Ogden Canyon Water Treatment Plant sludge as specified in our guidelines. Each incoming load is meticulously inspected to ensure compliance with our facility standards. Hazardous waste, materials containing invasive insects or pests, and PCBs are strictly prohibited. Employees receive annual training on identification and rejection of any unaccepted waste. See Appendix D for training documents and forms utilized by the Facility. If unpermitted waste is identified, the load will be rejected, and appropriate measures will be taken to ensure it does not enter the Facility. Starting in December 2024, rejected loads are noted in daily operating records. Special Precautions for Operating During Various Weather Conditions The Facility is generally unimpacted by various weather conditions as it maintains operation year-round. Power outages do not impact operation because equipment is not run on electricity and office staff can conduct services using paper forms which is then imported to computer databases later. Ogden City Green Waste Composting Facility – Plan of Operations Last Revision: 2024 8 | P a g e Wind Preceding large windstorms, the Facility accepts windblown trees and branches which results in increased operational and storage demand as well as a surplus of compost product. However, this has never resulted in disrupted services. Unsold product is given away, donated, or delivered to the Landfills. Dust Mitigation Dust is mitigated by applying water to the piles. Further dust mitigation is established by the berm perimeter which reduces wind loading on the windrows. There are typically 6 – 7 windrows at the Facility at any given time. Heavy Rain During heavy rain events, pools of water buildup on the West and North side of the Facility as shown in Appendix A. Pooled water is then used for moisture control in the windrows. Refer to the Section above for details on the contingency plan in case of failure of the containment system. Snow and Freezing Conditions The Facility has not experienced any issues in dealing with snow and freezing conditions. Excess snow is utilized in windrows to supplement moisture control and freezing conditions result in increased caution for operators and customers to prevent slip hazards. Annual Report The Ogden City will prepare and submit an annual report, as required in R315-302-2(4). Each annual report will be placed in the Facility's operating record discussed in the next section. The annual report will also be submitted to the Director by March 1st of each year for the most recent calendar year or fiscal year of facility operation. The annual report will cover Facility activities during the previous year and will include, at least, the following information: • Name and address of the facility; • Calendar year covered by the report; • Annual quantity, in tons, of solid waste received. Since the amount of waste received must be reported in tons, the following conversion factors shall be used for waste received that is not weighted on scales. o 0.25 tons per cubic yard for green waste o 0.40 tons per cubic yard for Ogden City drinking water treatment plant sludge • Training programs or procedures completed. Records Retention Operational records shall be maintained during the life of the facility and during the post -closure care period, which include, at a minimum, temperature data and quantity and types of material processed. Records for the Facility are stored in the Ogden City Operations file folder at this file path: X:\PW-OPS\REFUSE REFUSE Composting Process The Facility is managed in accordance with the Standard Operating Procedures (SOPs) that are attached in Appendix D. Ogden City Green Waste Composting Facility – Plan of Operations Last Revision: 2024 9 | P a g e Process Timeline It is estimated that the process time for compost at the Facility is between 90 – 120 days from initiation of the composting process to completion. No waste materials collected for the purpose of processing remain on site longer than two years. Weights and Volumes The typical daily volumes of green waste received from residents at the Facility is approximately 38 yards. The Facility does not utilize a scale to weigh vehicles and delivered waste. All measurement of materials received at the Facility are conducted visually on a volume basis using the form titled Green Waste Drop Off Scale. This form has been included in Appendix D. The volumes of waste are then recorded in the Fiscal Year Metrics spreadsheet where all historic volume records have been stored since the start of operation at the Facility. The last 5 years of metrics have been included in Appendix E. Compost product sold is measured utilizing the skid steer bucket which holds approximately ½ yard of compost. Since the amount of waste received must be reported to DWMRC in tons, the following conversion factors shall be used for waste received that is not weighted on scales. • 0.25 tons per cubic yard for green waste • 0.40 tons per cubic yard for Ogden City drinking water treatment plant sludge Windrow Construction The compost operations use a windrow layout. The size of each windrow is approximately 140 – 150 feet in length, 20 – 25 feet in width, and 12 – 13 feet in height. Moisture Management Water content is assessed by utilizing a squeeze test where a handful of compost is taken from about 18–24 inches within the pile and is squeezed tightly. The compost water content is maintained to a point where, when squeezed, the material is tacky and sticks together which means the moisture content is approximately between 49 – 54% moisture which is the desired consistency. If the squeeze test results in dripping water, then there is too much moisture, and the pile is then spread to allow to dry. Temperature and Aeration Management The temperature and aeration of the piles can be adjusted by the surface area, turning frequency, and water content. All these methods are used and modified as necessary; however, each row is turned utilizing a front- end loader and watered utilizing a sprinkler system at a minimum of once every 15 days. This 15-day turning frequency ensures the growth of aerobic microorganisms. Each row is turned 6 - 8 times until the temperatures no longer increase. A 6-foot temperature probe is inserted at the top of the windrow pile to a depth of approximately 4 – 5 feet. Temperature measurements of each windrow are taken in three locations approximately every 2 weeks. The measurements are taken about 8 – 10 feet inward from each end and one in the center. Temperature measurements are then recorded in a temperature log and kept with all other records of the Facility. A sample of the temperature log has been included in Appendix E. It can be seen in the temperature log that each pile is assigned a number, and each pile has 3 recorded temperatures on each date that temperature is taken. Temperatures of the windrow piles are typically maintained between 130- and 160-degrees F. Temperatures measured decrease during winter months, especially in the most northeast pile due to wind conditions and cold temperatures resulting in a slowed decomposition rate. During cold months, temperatures are sometimes Ogden City Green Waste Composting Facility – Plan of Operations Last Revision: 2024 10 | P a g e reported as low as 40 degrees F when piles are first started. However, temperatures of newly developed piles quickly rise to typical composting temperatures within several days. Windrow piles are required to reach at least between 140 – 160 degrees to ensure proper composting, but compost temperatures are retained between 104 and 149 degrees Fahrenheit for at least a period of five days and reach a temperature of not less than 131 degrees Fahrenheit for a minimum consecutive period of four hours during the five-day period. Windrows are not allowed to go beyond 160 degrees to avoid fire hazards and killing of microorganisms. Controlling Disease Vectors Controlling disease vectors on a green waste compost site is essential for maintaining a healthy environment and preventing disease spread. Key procedures implemented at the Facility include: • Ensuring proper drainage to avoid waterlogging • Regular site maintenance • Managing compost temperature to kill pathogens and pests • Covering compost piles with mulch as needed, turning them regularly, and conducting frequent inspections help reduce pest attraction and identify issues early • Implementing insect and rodent control measures • Avoiding contaminants • Training staff on vector management Testing, Monitoring, and Inspections Starting the 2024, the Facility is inspected daily by Facility employees to prevent malfunctions and deterioration, operator errors, and discharges that may cause or lead to the release of wastes to the environment or to a threat to human health. The Facility Daily Inspection Form (attached in Appendix D) are filled out and kept in an inspection log which includes the date and time of inspection, the printed name and handwritten signature of the inspector, a notation of observations made, and the date and nature of any repairs or corrective action. The completed Facility Daily Inspection Forms are kept at 133 W 29th St at the Public Works Building. These inspection records are maintained for at least three years from the date of inspection. Inspection records shall be available to the director or the director's authorized representative upon request. The schedule of testing, monitoring, and inspections conducted at the Facility to ensure proper operation and maintenance is provided on the table below. Monitoring and inspection equipment list and monitoring forms are housed in the main office and are provided in Appendix D. Monitoring and Inspection Schedule Inspection/Monitoring Activity Frequency Compost Quality Testing (Lab Test) Quarterly Windrow Temperature Every two weeks Access Road Condition and Maintenance During operation as needed Storm Water Pollution Prevention Monthly (See appendix D) Perimeter Berm Inspection Weekly and as needed Drainage Following storm events Asphalt and Concrete Surfaces Daily Equipment Maintenance Daily Ogden City Green Waste Composting Facility – Plan of Operations Last Revision: 2024 11 | P a g e Compost Quality Testing (Lab Test) On a quarterly basis, a sample of the processed compost is sent for laboratory testing at the Utah State University Analytical Lab located in Logan, Utah. The compost test at Utah State University analyzes key elements like nitrogen, phosphorus, potassium, micronutrients, moisture, pH, and salinity to assess the nutrient content. This helps determine optimal application rates to improve soil health and prevent nutrient imbalances or environmental issues. A test report for a sample tested on April 29, 2024 has been included in Appendix C. It is important to note that, while the test report indicates that it is a “Manure Report”, no manure is accepted or processed at the Facility. The finished compost also does not contain sharp inorganic objects and is sufficiently stable that it can be stored or applied to land without creating a nuisance, environmental threat, or a hazard to health. Storm Water Pollution Prevention Storm Water Pollution Prevention Plan (SWPPP) Inspections are conducted utilizing the SOP titled FORM 4.2.6.5 High Priority Facility SWPPP Inspection Form which is attached in Appendix D. Blown trash is picked up on a daily basis and SWPPP inspections are conducted monthly. Equipment Maintenance Equipment which exists on site includes a loader, skid steer, log splitter, and various smaller lawn equipment. This equipment is checked daily and maintained as needed and in accordance with Appendix D documents. In the case that any of this equipment fails or breaks down, the equipment is sent to Ogden City’s Fleet department (175 W 29th St) to repair. During repair time, alternate equipment owned by Ogden City is utilized to facilitate continued operations of the Facility. This Facility does not utilize equipment such as leachate and gas collection systems, or groundwater monitoring systems. Due to the types of waste processed at the Facility, these types of monitoring systems are not required. Closure Within thirty days of closure, the state will be notified of the intent to close the site and the following operations will occur: • Transfer unprocessed green waste, wood chips, and other organic materials to the Landfills for proper disposal. • Finished compost would be used on disturbed areas of the site, sold or stockpiled for final cover applications. • The site would be revegetated to obtain stabilization. • The asphalt pad would not be removed. • The Facility would be recorded with the county recorder as part of the record of title, a plat and statement of fact that the property has been used as a composting facility. • Record with the county recorder as part of the record of title, a plat and statement of fact that the property has been used as a composting facility. Post Closure Activities will be consistent with requirements established in R315-312-3(5)(b). . If required, the post-closure care and monitoring shall be for five years and shall consist of the maintenance of any monitoring equipment and sampling and testing schedules as required by the Director. Ogden City Green Waste Composting Facility – Plan of Operations Last Revision: 2024 12 | P a g e Once the Facility is closed, Ogden City Corporation anticipates on utilizing the site for other uses such as, but not limited to, expanding the cemetery in the composting site boundary within the post closure care period. Ogden City has discussed this intended use with personnel in the Division of Waste Management and Radiation Control and has received confirmation that this type of use would be approved so long as any necessary monitoring or assessments of the site, as required by the Director, are completed and deemed satisfactory for the intended use.
