Sincerely, l M. Kevin Weston kweston @s mithfield.com www.smithfieldfoods.com 1/3/2013 NUTRIENT UTILIZATION PLAN Owner(s): Facility Name: County: Facility Type: Storage Structure: Storage Period: Application Method: Murphy -Brown, LLC Warsaw Sanitation TW Duplin Trailer Wash Anaerobic Lagoon 76.5 Irrigation The wastewater from your facility must be land applied at a specified rate to prevent pollution of surface water and/or groundwater. The plant nutrients in the wastewater should be used to reduce the amount of commercial fertilizer required for the crops in the fields where the waste water is to be applied. This nutrient utilization plan uses nitrogen as the limiting nutrient. Wastewater should be analyzed before each application cycle. Annual soil tests are strongly encouraged so that all plant nutrients can be balanced for realistic yields of the crop to be grown. Several factors are important in implementing your nutrient utilization plan in order to maximize the fertilizer value of the wastewater and to ensure that it is applied in an environmentally safe manner. These factors are to be used as guidance. 1. Always apply wastewater based on the needs of the crop to be Grown and the nutrient content of the wastewater. Do not apply more nitroeer than the crop can utilize 2. Soil types are important as they have different infiltration rates, leaching potentials, cation exchange capacities, and available water holding capacities. 3. Normally waste shall be applied to land eroding at less than 5 tons per acre per year. Waste may be applied to land eroding at 5 or more tons per acre annually, but less than 10 tons per acre per year providing that adequate filter strips are established. 4. Do not apply waste on saturated soils: when it is raining, or when the surface is frozen Either of these conditions may result in runoff to surface waters which is not allowed under DWQ regulations. 5. Wind conditions should also be considered to avoid drift and downwind odor problems. 6. To maximize the value of the nutrients for crop production and to reduce the potential for pollution, the waste should be applied to a growing crop or applied not more than 30 days prior to planting a crop or forages breaking dormancy. Injecting the waste or disking will conserve nutrients and reduce odor problems. 1of8 This plan is based on the wastewater application method shown above. If you choose to change methods in the future, you need to revise this plan. Nutrient levels for different application methods are not the same. The estimated acres needed to apply the wastewater is based on typical nutrient content for this type of facility. In some cases you may want to have plant analysis made, which could allow additional wastewater to be applied. Provisions shall be made for the area receiving the wastewater to be flexible so as to accommodate changing wastewater analysis content and crop type. Lime must be applied to maintain pH in the optimum range for specific crop production. AMOUNT OF PLANT AVAILABLE NITROGEN PRODUCED PER YEAR (Ibs): Applying the above amount of wastewater is a big job. You should plan time and have appropriate equipment to apply the wastewater in a timely manner. LAND UTILIZATION SUMMARY The following table describes the nutrient balance and land utilization rate for this facility Nate that the Nitrogen Balance for Crops indicates the ratio of the amount of nitrogen produced on this facility to the amount of nitrogen that the crops under irrigation may uptake and utilize in the normal growing season. Total Irrigated Acreage: 32.46 Total N Required 1st Year: 8509.32 Total N Required 2nd Year: 5380.26 Average Annuaf Nitrogen Requirement of Crops: 6,944.79 Total Nitrogen Produced by Facility: 3,219.30 Nitrogen Balance for Crops: (3,725.49) The following table describes the specifications of the hydrants and fields that contain the crops designated for utilization of the nitrogen produced on this facility. This chart describes the size, soil characteristics, and uptake rate for each crop in the specified crop rotation schedule for this facility. 2 of !! :!■!!!2■■■■■■ | |k §■!!!])|§||f§ !| ------------- /k ----------------- f- .\f1+IT1 ƒ . . ....zzzzz_,z � � � _! lr;raaR�:�,;, � ■ §! :§■§!!u§¥!#K( ,I � ;, § !, 888 .... rr „ j !® 4■�4e77;P7K4§ - f !/ 2a220;4MRR � : ,# {| /!;)#f)$f$))) - ,<!!!)@)) W 00)\!I.N ,;\ < /� � IS MIN This plan does not include commercial fertilizer. The facility should produce adequate plant available nitrogen to satisfy the requirements of the crops listed above. The applicator is cautioned that P and K may be over applied while meeting the N requirements. In the future, regulations may require these facilities to have a nutrient management plan that addresses all nutrients. This plan only addresses nitrogen. In interplanted fields ( i.e, small grain, etc, interseeded in bermuda). forage must be removed through grazing, hay, and/or silage. Where grazing, plants should be grazed when they reach a height of six to nine inches. Cattle should be removed when plants are grazed to a height of tour inches. In fields where small grain, etc, is to be removed for hay or silage, care should be exercised not to lei small grain reach maturity, especially late in the season (i.e. April or May). Shading may result if small grain gets too high and this will definitely interfere with stand of bermudagrass. This loss of stand will result in reduced yields and less nitrogen being utilized. Rather than cutting small grain for hay or silage just before heading as is the normal situation, you are encouraged to out the small grain earlier. You may want to consider harvesting hay or silage two to three times during the season, depending on the time small grain is planted in the fall. The ideal time to interplant small grain, etc, is late September or early October. Drilling is recommended over broadcasting. Bermudagrass should be grazed or cut to a height of about two inches before drilling for best results.

Actual total acres in the fields listed may, and most likely will be, more than the acres shown in the tables. See attached map showing the fields to be used for the utilization of this wastewater. 4 of SLUDGE/GRIT APPLICATION: The following table describes the Plant Available Nitrogen produced per year in the sludgelgrit The nutrient utilization plan must contain provisions for periodic land application of sludge/g6l at agronomic rates. The sludge/grit will be nutrient rich and will require precautionary measures to prevent over application of nutrients or other elements. Your wastewater facility will produce approximately 47.158 pounds of plant available nitrogen per year will in the lagoon sludge/grit based on the rates of accumulation listed above. If you remove the sludge/grit every 5 years, you will have approximately 235.79 pounds of plant available nitrogen to utilize. Assuming you apply this PAN to hybrid bermuda grass hayland at the rate of 300 pounds of nitrogen per acre, you will need 0.785966666666667 acres of land. If you apply this PAN to corn at a rate of 125 pounds per acre, you will need 1.88632 acres of land. Please note that these are only estimates of the PAN produced and the land required to utilize that PAN. Actual values may only be determined by sampling the sludge/grit for plant available nitrogen content prior to application Actual utilization rates will vary with soil type, crop, and realistic yield expectations for the specific aoplication fields designated for sludge/grit appheation at time of removal. APPLICATION OF WASTE BY IRRIGATION The irrigation application rate should not exceed the intake rate of the soil at the time of irrigation such that runoff or ponding occurs. This rate is limited by initial soil moisture content, soil structure, soil texture, water droplet size, and organic solids. The application amount should not exceed the available water holding capacity of the soil at the time of irrigation nor should the plant available nitrogen applied exceed the nitrogen needs of the crop. If surface iuigation is the method of land application for this plan, it is the responsibility, of the producer and irrigation designer to ensure that an irrigation system is installed to property irrigate the acres shown in the preceding table. Failure to apply the recommended rates and amounts of nitrogen shown In the tables may make this plan invalid. 'This is the maximum application amount allowed lot the soil assuming the amount of nitrogen allowed for the crop is not over applied. In many situations, the application amount shown cannot be applied because of the nitrogen limitation. The maximum application amount shown can be applied under optimum soil conditions. Your facility is designed for Duplin of temporary storage and the temporary storage must be removed on the average of once every 4 months. In no instance should the volume of the wastewater stored in your structure be within the 25 year 24 hour storm storage or two feet of freeboard except in the event of the 25 year 24 hour storm. It is the responsibility of the producer and wastewater applicator to ensure that the application equipment is operated properly to apply the correct rates to the acres shown in the tables. Failure to apply the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid. Call your technical specialist after you receive the wastewater analysis report for assistance in determining the amount of wastewater per acre to apply to achieve the proper application amount prior to applying the wastewater. 5 of Application Rate Guide The `.ollowing is provided as a guide for establishing application rates and amounts.

The rate is 30 Ibs Wac and application window, is Sept -April. The total N applied to this cover crop must be deducted from the following crops starting PAN fate. The grit from the grit separator at this facility may be applied to the sprayfields at agronomic rates using NCDA Lab anallical results of the grit. These applications will be recorded on SLUR-2 forms and the Copper and Zinc levels will be monitored by the NCDA & CS soil test Cu-1 and Zn-I. If these index levels reach 2000, producer should start looking for alternative sites. If these index levels reach 3000, applications should cease on these sites.
