PRODUCT LABEL AND ANALYTICAL INFORMATION.................................G GARRETT EAv27 & MOORE Engineering for the Power and Waste Industries WALLACE FARM, INC. 1.0 GENERAL LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE Wallace Farm, Inc. (herein also referred to as Wallace Farm) operates a Large Type 3 Compost Facility on Eastfield Road, Huntersville, Mecklenburg County, North Carolina. The facility processes various types of feedstocks, including animal manures, yard waste, wood waste, land clearing debris, waste water treatment residuals, cotton and tobacco materials, food and/or animal processing residuals, and food waste. All of the feedstocks used at the facility are non- hazardous. (Further details on materials for composting operations are detailed below.) These operations offer environmentally friendly options to landfills, help ease environmental and energy burdens on the state, and produce useful end -products, while helping meet the state's recycling goals. General Statute 130A-309.04 calls for reducing the public's use of, and reliance upon, landfills. Composting is a key, preferred method for achieving this goal. With its green operations, Wallace Farm enhances and promotes this critically important goal for all citizens of North Carolina. The accompanying permit documents have been compiled to meet requirements of the North Carolina Department of Environment and Natural Resources (NC DENR) Division of Waste Management - Solid Waste Section as outlined in the North Carolina Solid Waste Compost Rules - Section .1400 - Solid Waste Compost Facilities. 2.0 APPLICATION REQUIREMENTS This application addresses requirements for a Large, Type 3 Solid Waste Compost Facility, as detailed in the North Carolina Solid Waste Compost Rules - Section .1400. These materials were prepared under the supervision and direction of a professional engineer duly registered in the State of North Carolina. 2.1 PERMIT DRAWINGS A permit drawing, which includes a one-fourth mile map and site plan are included as an attachment to this report. 2.2 ZONING Documents from the unit of government having zoning jurisdiction over the site are included in Appendix A. 2.3 SITING AND DESIGN STANDARDS The following sections include description of how the solid waste composting operations comply with siting and design standards in Rule .1404 of the North Carolina Solid Waste Compost Rules. 2.3.1 FLOODPLAIN The solid waste composting operations are not within the 100-year floodplain. GARR ETT �. Page 1 of 23 & Moou I Engineering far the Power and Waste Industries WALLACE FARM, INC. 2.3.2 PROPERTY LINE BUFFER LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE Wallace Farm will operate such that the minimum 100-foot buffer from the property line to the solid waste composting area will be maintained. The permit drawings demonstrate compliance with the property line buffer. 2.3.3 RESIDENCES BUFFER This facility was permitted by NCDENR and has been in operation based on a 100-foot buffer from compost operations to the property line. A 500-foot buffer from residences is not applicable for this site because the facility was permitted prior to the existence of residences. 2.3.4 WELL BUFFER There are two water wells located on the Wallace Farm property. The wells are greater than 100 feet from the composting areas. There are also seven groundwater monitoring wells, as shown on the site plan. 2.3.5 PERENNIAL STREAMS/RIVERS BUFFER A minimum 50-foot buffer will be maintained between perennial streams/rivers and solid waste composting areas. The permit drawings demonstrate compliance with perennial stream/river buffers. 2.3.6 SURFACE WATER QUALITY STANDARDS Surface water is addressed through a number of means. Stormwater from compost areas is directed to a collection pond, which has a storage volume of approximately 2,000,000 cubic feet. Charlotte -Mecklenburg Utilities (CMU) has issued Wallace Farm a permit for routing water from this pond to the CMU wastewater system via a sewer line which traverses the Wallace Farm property. A copy of the renewed permit (effective on August 22, 2012) is provided in Appendix B. All details regarding flow rates, sampling and testing regimens, and reporting requirements, are stipulated in the CMU permit and other Appendix B information. Wallace Farm has been issued a storm water permit (a copy is included, in Appendix C) by the Division of Water Quality. Underground pipes, shown on the site plan, divert non - process stormwater runoff off -site. Passive treatment methods (including grassy areas) are in place. No known violations of water quality standards have ever occurred. 2.3.7 CLOSED -OUT DISPOSAL AREA The composting facility is not located over a closed -out disposal area. GARR ETT �. Page 2 of 23 & Moou I Engineering far the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE 2.3.8 ADEQUATE ACCESS A 25-foot minimum distance will be maintained around the periphery of the composting areas to allow adequate access by fire -fighting equipment. The permit drawings demonstrate compliance with adequate access. 2.3.9 SURFACE WATER REQUIREMENTS The site shall meet the following surface water requirements: (A)A site shall not cause a discharge of materials or fill materials into waters or wetlands of the state that is in violation of Section 404 of the Clean Water Act; No waters or wetlands of the state will be filled to construct or operate the proposed facility. (B) A site shall not cause a discharge of pollutants into waters of the state that is in violation of the requirements of the National Pollutant Discharge Elimination System (NPDES), under Section 402 of the Clean Water Act. Stormwater discharges for operations of the proposed facility are permitted in accordance with NPDES General Permit No. NCG 240000. (C)A site shall not cause non -point source pollution of waters of the state that violates assigned water quality standards. Stormwater discharges for operations of the proposed facility are permitted in accordance with NPDES General Permit No. NCG 240000. 2.3.10 GROUNDWATER REQUIREMENTS Soils at the facility are observed to have a texture finer than loamy sand for all waste receipt and storage, active composting, and storage areas. Appendix D includes an April 26, 2000 letter from the Division of Water Quality indicating that the composting operation has not been a factor affecting ground water quality. The seasonal high water table has been determined by Wallace Farm's geologist to be greater than two feet from the surface (see the May 9, 2008 letter in Appendix D). 2.3.11 PUBLIC ACCESS The facility will not allow uncontrolled public access. A fence surrounds the proposed facility on all sides and trespassing has never been an issue. Members of the public can only visit the facility operations when accompanied by a Wallace Farm employee. 2.3.12 SEDIMENTATION POLLUTION CONTROL LAW Stormwater discharges for operations of the facility are permitted in accordance with NPDES General Permit No. NCG 240000. GARR ETT �. Page 3 of 23 & Moou I Engineering far the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE 2.3.13 AIR POLLUTION CONTROL REQUIREMENTS The facility will be operated to meet air pollution control requirements to minimize fugitive odorous emissions and to minimize odors at the property boundary. Minimize means to reduce to the smallest amount, extent, or degree reasonably possible. Operational procedures for maintaining aerobic conditions within the compost piles will be applied to minimize odor generation. These procedures include adjusting the porosity, moisture content and pH of mixes. Additionally, the carbon to nitrogen (C:N) ratio of the initial mix will be greater than 20:1 to minimize the release of nitrogen based compounds such as ammonia. An additional step that will be utilized, when necessary, is covering windrows with carbonaceous materials, as described in Section 2.6 and in the O&M Manual. Conveyors have been added to two spreaders to apply a layer of carbonaceous materials to windrows after formation and following turning. 2.4 FEEDSTOCK AND MATERIAL TYPES Feedstocks to be composted under this permit include animal manures, wood materials, yard waste, cotton materials, food and/or animal processing residuals, food waste, waste water treatment residuals, grease trap residuals, US domestic tobacco material, wood ash, cardboard, bleaching clay, cosmetics production materials, virgin gypsum board, lime, and starch water. Wood materials to be composted at the facility under this permit include land clearing debris, yard waste, wood shavings, sawdust, and pallets. Wood materials are from ground and unground land clearing debris and pallets. Ground and unground yard waste is generated by local municipalities and the general public. The wood shavings are generated from sawmill and furniture manufacturing operations. No wood materials will have been painted, stained, glued, or treated. The ash is from facilities that have received approval from NCDEQ or DWQ for ash distribution. The food processing residuals result from biological treatment of animal and/or food processing wastewater (with no human components) and the food waste comes from vegetable, dairy, meat, and bakery products. No domestic wastewater is included in the food residuals, food waste, the cosmetic, or starch water waste streams. New waste streams will not be received until approval by the Division of Waste Management. The only feedstocks that are expected to have seasonal variations in availability are leaves, yard waste, and mulch. Leaves are seasonal and arrive in the fall and winter. Ground mulch typically arrives during the drier months of the year when land clearing jobs are undertaken. These factors vary depending upon the economy and the extent of construction activities. It is very important for Wallace Farm to stockpile this material when it is available to help make it through times when it is not. GARRETT Page 4 of 23 & MOORE E12 Engineering for the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE Estimated annual quantities of feedstocks are summarized in Table 1. Please note that, as can be shown in annual reports submitted by Wallace Farm, exact quantities received will vary from year to year and from feedstock to feedstock, and in some years certain feedstocks might not be available at all. Note also that approximately 26,000 to 40,000 tons per year of wood materials are estimated as going into Wallace Farm's mulch business. This business component involves grinding, coloring, and/or blending mulch products to be distributed in bulk or packaged form. GAMETT �.

Page 6 of 23 & MOOU I Engineering far the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE 2.4.1 DESIGN (OR MAXIMUM THROUGHPUT) CAPACITY The design capacity (or maximum throughput rate) of a windrow -based facility is a function of a number of factors, including composting, storage, and storage times. These factors can vary depending on operations approaches (composting has minimum time and temperature requirements, for example, but longer times may be used), market conditions, and sales outlets' timing and needs. One means of estimating the design capacity is to consider product mixing rates. Wallace Farm will not receive for composting more than 100,000 tons per year of material. Further, it is expected that the facility will receive approximately 40,000 tons of additional wood materials per year to be used for the mulching component of the facility. 2.4.2 SOILS Refer to Section 2.3.1 2.5 SITE PLAN The facility site plan is included in the permit drawings. 2.6 OPERATION DESCRIPTION Facility Operators are: • Eric Wallace 704-875-2975 ext. 17 • Tony Ramirez 704-224-7429 The following describes facility operations. Dry carbonaceous materials (including wood materials, yard waste, sawdust, wood shavings, and cotton materials) are delivered to the facility and off loaded in the receiving area. A 1564 Hogzilla tub grinder, multiple Volvo, John Deere, and Cat wheel loaders, and a 320 Cat excavator are used for regrinding land clearing debris and for grinding unground land clearing debris, yard waste, and pallets. Materials with significant water content (including food and/or animal processing residuals, waste water treatment residuals, manures, US domestic, tobacco waste, food wastes, cosmetics waste, and starch water) are unloaded directly into the concrete receiving/mixing pit for preparing compost mixes. The mixing pit can hold approximately 900 cubic yards of dry materials and approximately 120 tons of material with significant water content. The facility utilizes three cone -bottom 15,000 gallon vertical tanks. These tanks are used for off-loading shipments of high-water content feedstocks that arrive when the mixing pit is in use and/or filled to capacity. Use of the tanks helps maximize operations efficiency. (More detail on these tanks is provided in Section 2.7.) The receiving pit is concrete, 60' x 60' with 8" thick floors. The walls are 8' high and 10" thick. A concrete unloading and washout area is located above the pit. This area is 60' x 30' with 8" thick floors. (See the Concrete Pit Construction Specifications, Appendix E). GARRETT Page 7 of 23 & MOORE E12 Engineering for the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE Materials are blended in the mixing pit by thorough mixing using one or two Volvo, John Deere or Cat front end loaders at a rate of 300-400 yards per hour, targeting a homogenous mixture with a C:N ratio of 20:1 to 30:1 and a moisture content of 40-60%. After the last mixture is prepared and removed for further processing, the walls and dump areas are washed down with a high pressure hose. The wash water is directed into the pit, to which fresh bulking material is added on the bottom to absorb the moisture. Analytical laboratory results for incoming feedstocks are used to determine the quantity of each feedstock to use in each compost mix. The feedstocks will be sampled annually and such analytical results will be updated and provided to the Division. Parameters for each feedstock (%C, %N, moisture content, and bulk density) are entered into standard mass -balance equations for composting —those in use were originally acquired by Wallace Farm at one of the national composting schools. In addition, a standard computer spreadsheet is on -hand for verifying product mix ratios. Quantities of feedstocks used in mixtures are measured using two approaches: mass measurements of each feedstock load (known using tare readings), and by using the volume of the front end -loader buckets. When liquid wastes are stored, volumes routed to the mixing pit are measured from knowledge of the fraction of tank capacity utilized. Within two hours of blending, the mix is transported to the composting pad using dump trucks and placed into windrows. A front end loader is used to improve the shape of the windrows as necessary. Windrows are constructed approximately 14 - 16 feet wide, 5 - 7 feet high, and several hundred feet long. The windrows are turned periodically using a Backhus windrow turner to maintain aerobic conditions within the pile and to invert and fluff the windrow. The composting areas slope with the natural lay of the land to facilitate drainage and allow access during any weather conditions. Material generally remains in the turned windrows for approximately eight to sixteen weeks, followed by placement in a storage pile for a minimum of six months. The material achieves the process to further reduce pathogens (PFRP) requirements (as well as Vector Attraction Reduction requirements) in the windrows by maintaining pile temperatures at or above 131 °F for at least 15 consecutive days. Windrows are turned at least five times during the period when temperatures are >_ 131°F. During the PFRP period, temperatures are measured one time per week until requirements have been met. An oxygen meter is used to measure oxygen content of compost pile pore space, and usually is applied at the same time that temperatures are checked. Current process durations for the various steps are shown in Table 2. Working windrows vary from 5 - 7 feet in height by 14 - 16 feet in width. Cross -sections vary depending upon initial size at set-up, and due to shrinkage. Windrow lengths may vary. Other windrow sizes may be used, depending upon equipment settings, and other factors. GARR ETT �. Page 8 of 23 & Moou I Engineering far the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE Table 2. Process durations at Wallace Farm. Step Process duration Receiving 0.5 hours for weighing and removal • Storage of feedstocks and bulking agents up to 180 Days • Storage of high water content feedstocks up to 72 hours Preparation • 1 hour for each mixing pit loading • 2 days for each windrow Composting 8 to 16 weeks Storage 6 to 18 months Distribution • 36 months of onsite storage • Occurs all year, with increases in distribution occurring in the Spring and Fall. In the event that a batch of compost does not meet state or facility requirements for distribution, the material can be added to a new compost mix for reprocessing or applied to farm land. (Land application of compost not meeting state requirements must be pre - approved by NCDEQE.) If land is not available for land application, then an approved municipal solid waste landfill will be used as a last resort for disposal. After composting, the material is screened to approximately '/2-3/8 inch to prepare for marketing. The compost is marketed as Composted Cow Manure, Grade A Compost Plus, and Mushroom Compost. In addition, the compost is mixed with other materials to create a variety of products. These products include items such as Blended Top Soil, Planting Soils, and Potting Soils. These products are marketed in both bulk and bagged form. Many professional landscape organizations and retail outlets utilize the final products. In the event material cannot be marketed, it will be applied to pasture or farmland to supplement commercial fertilization practices. Personnel at Wallace Farm are trained to perform various work tasks on the farm and in conjunction with the composting operation. There is not a precise routine at the composting facility. Different personnel will work together to perform various operations on a given day. For example, moving material off of the composting pad to the storage pile may be the priority one week, whereas screening the material in preparation for marketing may be the priority the next week. GARR ETT I.. Page 9 of 23 & MOOU I Engineering far the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE Listed below are some general operations typically performed by personnel at the facility: • General Manager - Manage all operations and direct work efforts • Office Manager - Coordinates all billings and administrative activities • Fleet Manager - Coordinates all deliveries and trucking operations • Tractor Trailer and Dump Truck Drivers - Haul feedstocks and finished materials • Front End Loader Operator - Mixes feedstocks/shapes windrows/loads product/mixes and screens finished products • Compost Turner Operator - Turns windrows/monitors compost piles • Bagging Line Operator - Bags finished products The operation schedule varies as for other farm operations. Operations procedures may be performed seven days per week depending on the work to be accomplished. There are few routine tasks performed at the start of each day. Other than unlocking the buildings, work is resumed from the previous evening. For example, bagging lines are restarted, and compost mixing recommences. Activities performed at the end of each day include: washing down the concrete receiving area and mixing pit, removing keys from all trucks and equipment, locking fuel tanks and buildings. Airborne particulates are generally associated with dry compost. The initial mix solids content can be varied during mixing to prevent over drying of the piles during composting. In addition, water from the collection pond, or water from an on -site farm pond may be used to add moisture, if necessary. A tractor driven PTO (power take -off) pump is used to fill a 4,000 gallon Hydroforce water tank that is mounted on an International truck, and/or a 5,000 gallon Hydroforce water tank mounted on a Volvo, off -road truck. The water trucks are equipped with spray nozzles for applying water to travel areas and are equipped with specially designed nozzles for applying water to the top of compost windrows. Wallace Farm reports the following operational approach for meeting PFRP. During the first month following windrow formation, Wallace Farm targets turning windrows every 5-10 days. If necessary, water from the collection or a farm pond is added to windrows during this time, which is prior to the start of PFRP. PFRP is typically met during the second month of active composting. (As stated in the Rules (.1406 (12) (A)), for meeting PFRP, "Aerobic conditions shall be maintained during the compost process. A temperature of 131 degrees F (55 degrees Celsius) or greater shall be maintained in the windrow for at least 15 days. During the high temperature period, the windrow shall be turned at least five times." As noted above, Vector Attraction Reduction is accomplished by meeting PFRP requirements.) If additional GARRIETT Page 10 of 23 & MOORE ■ Engineering for the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE water is needed during this PFRP period, well water is used. After PFRP has been met, turning frequency is reduced to approximately every 10 days. Household wastes are not part of the Wallace Farm feedstocks, such that household hazardous wastes (nor any type of hazardous wastes) are not expected. If household hazardous wastes were delivered, they would be seen during unloading and/or during product mixing, and they would be removed and disposed of in an approved facility. 2.7 PROCESS FLOW The process flow is depicted in Figure 3, with further details in the Process Flow Fact Sheet which follows. Processing steps are described in following sections. The tonnage values are estimates only and are subject to change. The total annual quantity received for composting will not exceed 100,000 tons.

LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE • Topsoil o Approximately 75,000 cubic yards, 365 days 2.7.1 MATERIALS RECEIVING/PROCESSING Wood materials, yard waste, sawdust, wood shavings and cotton materials are delivered by truck to the site and unloaded in the receiving and bulking agent storage area. Grinding of wood materials will be performed with a 1564 Hogzilla Tub Grinder. Any contaminants such as metal or trash that are inadvertently mixed with the wood material are disposed of at a landfill. Manure, food processing residuals, and other feedstocks with high water content are delivered to the concrete receiving/mixing pit shown on the site plan for immediate processing. 2.7.2 MIXING Mixing is accomplished by a front end loader as described in Section 2.6. The mix is then moved by front end loader and dump trucks to a composting area. 2.7.3 COMPOSTING The mix is placed into windrows. A front end loader is used to shape the windrows, as required. Carbonaceous materials may be placed on top of the windrows to increase solids content to adjust the C:N ratio, or to minimize compost smells. The windrows are periodically turned with the Bachkus compost turner. Windrows are constructed approximately 14-16 feet wide at the base and 5-7 feet high and several hundred feet long. The temperatures are measured in each windrow once per week until PFRP is achieved by maintaining temperatures above or equal to 131 °F for a minimum of 15 consecutive days. Windrows are turned at least five times during this period in which temperatures are >_ 131 IF. (Vector attraction reduction is met by having temperatures higher than 104 Fahrenheit with an average temperature higher than 113 degrees for 14 days or longer.) Material remains in windrows for approximately eight to sixteen weeks during the active composting period. 2.7.4 STORAGE After active composting, material is stored in a storage pile for approximately six to twelve months prior to screening. Compost will be stored in the compost storage shed, or in large piles or windrows outdoors. The piles and windrows may be covered with vented plastic covers to keep the compost dry during wet weather. Final storage capacity for approximately thirty six months of compost production is available outdoors. Additionally, approximately twelve months of storage capacity is provided under a roof. 2.7.5 - Screening G2MMETT �� Page 16 of 23 & MOOU I Engineering far the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE The material is screened to approximately '/2-3/8 inch to produce a more marketable compost product. The overs (material greater than 3/8 inch in nominal size) are recycled and stored in the receiving area until being mixed with incoming feedstocks. 2.7.5 AIR EMISSIONS AND CONTROL TECHNOLOGIES Operational procedures as specified in the operation and maintenance manual, such as maintaining aerobic conditions within the composting process (through control of porosity, moisture content, oxygen levels, and proper turning), maintaining a neutral pH, and increasing the C:N ratio will be followed. In addition, nitrogen -containing materials will be handled promptly, helping prevent formation of nitrogenous compounds such as ammonia. All reasonable efforts will be made to avoid turning windrows during unfavorable weather conditions, such as inversion conditions and undesirable wind directions, to minimize odors beyond the facility boundary. Data from an onsite weather station will be monitored on a daily basis. Windrows will be covered with carbonaceous materials (taking care not to reduce air flow), if offensive odors are observed. Airborne particulates are generally associated with dry, dusty compost piles. The initial mix solids content can be varied during mixing to prevent over drying of the piles during composting. In addition, the water collected in the collection pond, or water from an on - site well and/or farm ponds may be used to add moisture back to the piles, if necessary. A tractor driven PTO pump is used to fill 4000 or 5000 gallon truck mounted Hydroforce water tanks. The water trucks are equipped with spray nozzles for applying water to travel areas and are equipped with specially designed nozzles for applying water to the top of compost windrows. Water from the collection pond and the farm pond is not added to windrows after the start of the PFRP period. The following conditions apply: 1. The odor management plan shall be followed to minimize odors at the facility boundary. In response to an odor complaint, the facility shall implement the measures set out within Section 2.7.6 of the operation and maintenance manual. 2. Upon receipt of a facility complaint, the facility operator shall investigate and take action as necessary to minimize the cause of the complaint. A copy of all complaints regarding this facility shall be maintained for the duration of the permit, including the operator's actions taken to resolve the complaints. 2.7.6 LEACHATE TREATMENT Stormwater from composting areas is routed using natural contours and installed diversion berms to the stormwater pond. Water from the stormwater pond is used on windrows that require additional moisture or dust suppression (but not during or after PRFP) and may be used for compost mixes. GARRETT Page 17 of 23 & MOORE E12 Engineering for the Power and Waste Industries WALLACE FARM, INC. 2.8 PRODUCT LABEL LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE A copy of the Wallace Farm product information sheets and product labels and compost (and feedstock) analytical data is included in Appendix G. The Grade A composted cow manure is registered with the NCDA as a fertilizer. The material is required to meet a minimum N-P- K value of .5-.5-.5. It is routinely tested by the NCDA Agronomic Division. Grade A compost plus and mushroom compost are registered with NCDA as a soil amendment. 2.9 ENGINEERING PLANS AND SPECIFICATIONS No additional site modifications are planned at present. Manufacturers' performance data for equipment utilized at the facility is included in Appendix F. 3.0 REQUIRED INFORMATION FOR OPERATING PERMIT The following section describes the information required for reviewing an application for a permit to operate the composting facility. 3.1 CONTINGENCY PLANS Contingency plans for unusual and adverse conditions are as follows: 3.1.1 EQUIPMENT BREAKDOWN Wallace Farm has a full time mechanic on staff, who routinely conducts regular equipment maintenance. Sufficient storage of the feedstocks is provided to allow for routine maintenance problems. If the compost turner breaks down, loaders can be used while it is under repair. Wallace Farm also maintains a good relationship with its vendors and can get equipment repaired quickly. However, equipment can be rented as necessary to maintain operations. 3.1.2 AIR POLLUTION/ODORS These approaches are described in Section 2.7.6. 3.1.3 NON -CONFORMING MATERIALS Incoming feedstocks will be inspected upon arrival. Non -conforming materials are not allowed on the site and visual inspection prevents this from being a problem. Any rocks found in shipments are removed. Plastics are not a factor; however these would be separated out, by hand, if present and placed in the on -site dumpster. G2MMETT �. Page 18 of 23 & Moou I Engineering far the Power and Waste Industries WALLACE FARM, INC. 3.1.4 SPILLS LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE Spills of non -composted material will be cleaned up by a front end loader and added to active compost piles. 3.1.5 FIRES The local fire department will be called if needed in the event of any fire at the facility. If piles of material catch on fire, a bulldozer and loaders will be used to separate the unburned material from the burning material and prevent the fire from spreading. 3.1.6 PARTICULATES Particulates are generally associated with overly dry compost piles. Water from on -site farm ponds, from the collection pond, or from an on -site well can be used to increase moisture content and reduce particulates. As noted above, addition of water from on -site ponds will not be performed after the start of PRFP. 3.1.7 NOISE Equipment normally associated with farm operations and grading operations has been used at this location for many decades and will continue to be used on the site. Reasonable levels of noise are expected. 3.1.8 VECTORS Vector attraction reduction takes place during composting. To meet vector attraction reduction, materials are to be treated in an aerobic process for 14 days or longer, during which time the temperature of compost shall be higher than 40 degrees Celsius (104 degrees F) and the average temperature shall be higher than 45 degrees Celsius (113 degrees F). Periodic turning occurs throughout the composting process, as discussed above and in the O&M Manual. This approach is considered very effective at controlling vectors. Nevertheless, Wallace Farm staff makes visual observations for vectors. The attraction of birds has never been an issue on the site. Process modifications will be made, if required, to ensure these vector attraction reduction requirements are met. This may include increasing the amount of wood material and cotton material in the initial mix. Mixing of incoming wet materials and bulking agents occurs is outlined in Section 2.6. Periodic turning occurs throughout the composting process, as discussed above and in the O&M Manual. 3.1.9 UNUSUAL TRAFFIC CONDITIONS Delivery schedules may be modified, if required, to prevent traffic impacts. 3.1.10 ADVERSE WEATHER CONDITIONS Operations will be curtailed as necessary during wind, heavy rain, snow, freezing or other adverse weather conditions. If conditions are very severe, feedstock delivery will be GARRETT �� Page 19 of 23 & Moou I Engineering far the Power and Waste Industries WALLACE FARM, INC. LARGE TYPE 3 COMPOST FACILITY HUNTERSVILLE, SITE stopped, and operations will cease. The compost turner, which runs on tracks, permits operations under all but the most severe conditions. Delivery and other operations will also be reduced to match staff absences due to inclement weather. 3.2 OPERATIONS AND MAINTENANCE MANUAL A separate operations and maintenance (O&M) manual for the facility has been prepared and is included with this permit application. 3.3 QUALITY ASSURANCE PLAN Detailed records, including quantity and type of incoming materials, outgoing products, pile temperatures, moisture and oxygen levels, turning frequency, and product testing will be maintained at the facility. Composite compost samples will be taken quarterly and compared to the standards shown in Table 4. Wallace Farm uses certified laboratories, and their testing procedures are noted on each lab analysis. Wallace Farm will test or obtain test data on the cotton material, food processing residuals, and other incoming feedstocks annually to ensure metals are below Solid Waste standards as shown in Section .1407. Non-compostable materials are not allowed on the site. Wallace Farm receives feedstocks of very consistent quality from known suppliers. This feedstock does not contain any sort of non-compostable materials. Should non-compostable materials be delivered, they will be sent back to those that sent them, if allowable by law. If hazardous materials are received, Wallace Farm will report to the Division of Waste Management immediately to seek solutions with them and determine proper removal and disposal procedures to follow. If non- compostable materials are screened from initial delivery, they will be separated and processed according to law. If they are non -hazardous, they will be routed to a landfill. If hazardous, Wallace Farm will follow directions of experts at the Division of Waste Management. GARRETT �� Page 20 of 23 & MOORE I Engineering far the Power and Waste Industries WALLACE FARM, INC.
