Jo L Averill Farms mainly consists of two dairies, Kilchis Mist Dairy and Averill Dairy, and a calf raising operation at the Idaville Farm. Jo L Averill Farms is owned and managed by Donny Averill and his family who are planning to milk 340 cows on the Kilchis Mist Dairy and 340 cows on the Averill Dairy. Approximately 100 heifers will be raised at the Kilchis Mist Dairy and 45 heifers and 15 bulls will be raised at the Averill Dairy. Approximately 280 calves will be raised on the Idaville Farm. The three facilities will be used, in conjunction with one another to best manage the dairy animal housing needs at various growth stages and the fields at those facilities for maximizing forage composition and yield. A request for consolidation of the permits for the Kilchis Mist Dairy, Averill Dairy and the heifer and calf operation at the Idaville Farm and a modification of permitted animal numbers from a maximum of 980 to 1,190 dairy animals is located in Section 5. The dry cows, heifers, calves and bulls on Jo L Averill Farms are out on pasture for varying times throughout the year as weather conditions permit. The animals will spend more time in the livestock barns and less time on the hay and pasture fields in the winter months and more time on the hay and pasture fields in the spring, summer and fall months and less time in the livestock barns. Mortalities that occur during the year on the Jo L Averill Farms are picked up and processed by a rendering service provided by the Tillamook Creamery Association. Manure Handling Most of the wastewater is generated by the dairy facilities and stored in the above and below ground concrete tanks until weather conditions allow application to the hay and pasture fields. Stored wastewater containing manure is applied to fields at agronomic rates by various methods including a big gun traveler or a tank wagon. Solids containing manure, bedding and wasted feed is mainly generated from calf hutches and livestock barns. This manure will be stored onsite in roofed storage facilities until weather conditions allow application to the hay and pasture fields at agronomic rates. Forage Jo L Averill Farms owns and leases 603 acres for the dairy and heifer facilities and the hay and pasture land fields used to produce forage for the dairy livestock. These acres consist of 23.9 acres for the dairies and heifer farm facilities, shops and houses and Jo L Averill Farms AWMP Page 1-3 Section 1 GENERAL INFORMATION 579.1 acres of irrigated hay and pasture land used to produce forage for the dairy livestock. The crop rotation for the Jo L Averill Farms consists of 5 to 7 years of perennial grass that is harvested by grazing livestock and for hay. Jo L Averill Farms also grows annual field corn for silage and a grass cover crop. The estimated yields for the irrigated grass harvested by grazing livestock and as hay ranges from 6 to 13 tons per acre at various dry matter percentages. The estimated yields for the irrigated field corn for silage is 20 tons per acre at 31% dry matter and the estimated yield for the grass cover crop is 10 tons per acre at 61% dry matter. Nutrient Management Performance based nutrient management will be employed to insure nutrient balance on all fields. Forage yield will be tracked annually and used to determine the rate of manure application on a per field basis. Manure will be tested annually and tested values will guide application rates. Actual yield varies from year to year depending upon weather conditions and specific field management. All fields are well managed and in good condition. The soil concentration of phosphorus ranges from low to high in the Jo L Averill Farms hay and pasture land fields. Applications of wastewater and solids containing manure are planned on a nitrogen basis on all fields based on the fields having a medium phosphorus index rating. The soil phosphorus concentrations in the hay and pasture fields will be monitored using soil tests. Some solids containing manure may have to be exported off farm if the soil concentrations of phosphorus increase significantly in the future. It is estimated that the dairy does not produce enough manure to meet the nutrient demand for the hay and pasture land fields. Supplemental nutrient applications to the hay and pasture land fields should be based on soil tests and fertilizer guides to prevent excess soil nutrient concentrations.

The planned number of dairy animals for Jo L Averill Farms consists of 750 milk and dry cows and 425 heifers and calves and 15 bulls. A request to consolidate permits for the Kilchis Mist Dairy, Averill Dairy and Idaville heifer and calf farm and modification of permitted animal numbers is located in Section 5. This plan was written based on 1,190 dairy livestock and land base described herein. ANIMAL MORTALITY MANAGEMENT Currently animal mortalities for the Jo L Averill Farms are being disposed of by a rendering service provided by the Tillamook Creamery Association. Other methods of dealing with mortalities may be employed by Jo L Averill Farms as needed. Having dead animals sent to an acceptable disposal site is the best method to deal with animal mortalities. A list of landfills and phone numbers can be found on the internet at http://www.deq.state.or.us/lq/sw/disposal/permittedfacilities.html. If a local landfill is not permitted to accept animal carcasses, the Oregon Department of Environmental Quality (DEQ) may grant an exception. Phone numbers to local DEQ offices can be found in most phone books or on the internet at http://www.deq.state.or.us/about/locations.html. Under no circumstances are animal mortalities to be disposed of in any type of liquid manure storage facility. COLLECTION OF MANURE, PROCESS WATER AND RUNOFF Manure, bedding and wasted feed is collected in the livestock barns. The estimated volume of Manure bedding and wasted feed that will be collected annually was generated using the ORAWM workbook located in Section 5. Rainfall runoff from paved and unpaved areas that comes into contact with animal manure is directed to catch basins that drain to the wastewater collection tanks. The estimated volume of rainfall runoff that will be collected annually was generated using the ORAWM workbook located in in Section 5. All rainfall runoff from roofs is directed to drainage ditches. All process water from the dairy operations is directed to catch basins that drain to wastewater collection tanks. The estimated volume of process water that will be collected annually was generated using the ORAWM workbook located in Section 5. TREATMENT FACILITIES The separated solids are composted and recycled for bedding. STORAGE FACILITIES Capacities and estimate volumes to store for the waste storage facilities can be found on the Manure Storage and Nutrient Balance Summary on page 1-5. Jo L Averill Farms AWMP Page 2-1 Section 2 PRODUCTION AREA TRANSFER OF MANURE, PROCESS WATER AND RUNOFF Wastewater, manure, bedding and wasted feed from the livestock barns is directed to collection tanks where it is pumped to the separation facility to separate solids from the wastewater stream. Wastewater from the separation facility is directed to the above ground wastewater storage tanks and separated solids are transferred to the solids storage facilities shown on the Production Area Map on page 2-9. Wastewater stored in the above ground wastewater storage tanks is pumped to the hay and pasture fields using underground pipelines transferred using a tank wagon to be utilized as a source of nutrients. Traveling big gun irrigation systems, traveling big gun spreader bar systems, tractor pulled tank wagons, and truck tankers are used to apply the wastewater at agronomic rates to the hay and pasture fields. Solids stored in the solids storage facilities are hauled to the hay and pasture land fields and applied at agronomic rates using a tractor pulled solids spreader to be utilized as a source of nutrients. Wastewater and Solids will be transferred from farm to farm as needed to maximize storage capacity. Jo L Averill Farms AWMP Page 2-2 Section 2 PRODUCTION AREA OPERATION AND MAINTENANCE CONSIDERATIONS WASTEWATER COLLECTION AND STORAGE TANKSThe wastewater collection and storage tanks shown on the Production Area Map on page 2-9 are used to store wastewater containing manure generated by the Jo L Averill Farms. The storage capacity and estimated storage period for the wastewater collection and storage tanks are shown on the Manure Storage and Nutrient Balance Summary on page 1-5. Emptying of the wastewater collection and storage tanks should begin in the spring and continue through the spring and summer months as weather conditions permit applying wastewater in accordance with the guidance given in Section 3, Utilization Area. To function properly and have the greatest management flexibility, the wastewater collection and storage tanks must be as empty as possible in the fall before the fall and winter rainy season begins. Any annual buildup of solids in the wastewater collection and storage tanks must be removed to maintain design capacity and applied to land application areas in accordance with guidance given in Section 3, Utilization Area. Inspect all tanks weekly to insure structural integrity. If the structural integrity of a tank is compromised, immediately empty the tank to determine the cause and make necessary repairs before putting the tank back into service. Do not allow equipment that exceeds the design limit of the tanks on or within 20 feet of the structure. Inspect all uncovered tanks on a biweekly basis to insure at least 1 foot of freeboard is being maintained to accommodate excess rainfall such as a 25 year-24hour storm and prevent overtopping of the tank. Keep pumps, agitators, piping, valves and all other electrical and mechanical equipment in good condition by following the manufacturer’s recommendations. Maintain grounding rods and wiring for all electrical equipment in good condition. Immediately remove all foreign debris within the structure that may cause damage to pumps or agitators. Pump the wastewater collection and storage tanks completely empty during the summer months and cleanout any debris and other solid materials that may have accumulated in the tanks. Inspect the tanks for structural damage and if structural damage to a tank is discovered seek the services of a qualified engineer to assess the damage and recommend necessary repairs before putting the tank back into service. Follow the guidance given in Section 3, Utilization Area, when applying wastewater to fields. Do not dispose of animal carcasses in any wastewater collection and storage tank. It is against the law to do so. Maintain all fences, railings, and/or warning signs to provide warning and/or prevent unauthorized human or livestock entry. Immediately repair vandalism, vehicular or livestock damage to the structure, earthen areas surrounding the structure, or any appurtenances. Maintain lids, grates and shields on openings. Provide proper ventilation before entering the tank, for any reason what so ever. Provide and use self - contained breathing apparatus (scuba) equipment when entering a tank. No persons should enter the tank unless safety ropes are used and someone else capable of providing rescue assistance is outside the tank. Jo L Averill Farms AWMP Page 2-3 Section 2 PRODUCTION AREA Do not assume any tank, including open top tanks, are well ventilated. SOLIDS STORAGE FACILITIESThe solids storage facilities shown on the Production Area Map on page 2-9 are used to store solids containing manure generated by the Jo L Averill Farms. The storage capacity and estimated storage period for the solids storage facilities are shown on the Manure Storage and Nutrient Balance Summary on page 1-5. Emptying of the solids storage facilities should begin in the spring and continue through the spring and summer months as weather conditions permit applying solids in accordance with the guidance given in Section 3, Utilization Area. To function properly and have the greatest management flexibility, the solids storage facilities must be as empty as possible in the fall before the fall and winter rainy season begins. Periodically inspect concrete and asphalt slabs, walls and curbs and repair or replace broken sections as needed. Cleanup any spillage of manure and organics from outside of the solids storage area and place them back in the solids storage facilities. Maintain all fences, railings, and/or warning signs to provide warning and/or prevent unauthorized human or livestock entry. Immediately repair vandalism, vehicular or livestock damage to the structure, earthen areas surrounding the structure, or any appurtenances. BUILDING ROOFSInspect building roofs annually as a minimum. Repair and/or replace all rusted sections and secure loose sections as needed. Immediately replace all broken trusses, rafters, beams, poles as needed. Immediately determining the cause and necessary modification(s) to prevent reoccurring structural failure is essential. COMPOSTING The cause for any excess leachate from the composting process during the seasonal composting process performed in farm fields will be determined the operator will determine the cause of the excess leachate and take immediate corrective action such as turning the windrow pile(s) and inspecting the feedstock and compost for the presence of excess leachate. Guidance for the composting processTake a representative sample of the raw compost mixture and have a laboratory determine the moisture content, pH, and the carbon and nitrogen content. The carbon to nitrogen ratio should range between 25 and 40 to 1. Make adjustments as needed to the ingredients of the raw compost mixture as necessary to achieve a carbon to nitrogen ratio within the acceptable range. The moisture content should be between 40 and 60 percent. Add water or drier material to adjust the moisture content. Care must be taken to see that the carbon to nitrogen ratio of the mix is still in the 25 – 40 to 1 range after adjusting the moisture content. The pH preferably should range between 6.5 and 8 however composting may be achieved between a pH of 5.5 and 9.0. Jo L Averill Farms AWMP Page 2-4 Section 2 PRODUCTION AREA Check pile temperature using thermometer probe on a daily basis. The pile temperature should be checked at a point one-third the distance from the outside of the pile to the center of the mass. Initially it will take approximately 2 to 3 days for the compost to get above 105 degrees F. Compost temperatures should peak between 130 and 140 degrees F in 5 to 7 days. When the temperature of the compost material falls below 110 degrees F the compost needs to be aerated by turning or other means. Failure to achieve the desired temperatures may result in the incomplete destruction of pathogens and weed seeds and can cause fly and odor problems. Odors given off by the composting operation is a good indicator of how the compost operation is proceeding. Foul odors may mean that the process has turned from aerobic to anaerobic. Anaerobic conditions are the result of insufficient oxygen in the compost. This may be caused by excessive moisture in the compost or the need for turning or aerating of the compost material. For a well managed windrow or static pile composting operation, the composting time during the summer months should range from 14 days to a month. To ensure a finished compost, observe that the composted material has little or no trace of the original raw material and has little odor. The material should be black to brown in color. Particle size should be consistent and soil-like in texture. All materials that are not considered feedstocks for the composting process (i.e. plastic ear tags, plastic gloves, etc…) are to be collected and transported to a permitted landfill by a garbage collection service or other means. It is anticipated that there will be no other material that will require offsite disposal. FENCESDo not allow livestock access to open water courses and drainageways. Provide off stream watering facilities where possible and limit access to designated watering areas. Inspect fences periodically and repair or replace broken or decayed posts and tighten sagging wire as needed. Broken wire can be spliced or replaced. Replace broken or missing insulators on electric fences as needed and repair or replace inoperative electric fence controllers. Insure gates and other appurtenances are in good working order. Replace or repair components as needed. Jo L Averill Farms AWMP Page 2-5 Section 2 PRODUCTION AREA IRRIGATION SYSTEMSMaintain sprinkler irrigation systems in accordance with the manufacturer’s recommendations to help ensure trouble free operation. Prevent livestock access to equipment during operation. Clean plugged nozzles and replace if worn or defective. Promptly repair all leaks by replacing valves, fittings, gaskets, worn or damaged parts. Prompt repair or replacement of damaged or worn components is necessary. Check to make sure all application components i.e. water control structures, gates, valves, ditches, etc. are functional and are in good operating condition. Maintain screening and filtering facilities. Maintain vigorous vegetative growth where applicable. LIVESTOCK WATERING FACILITIESCheck all above ground connections, valves, gates, rodent guards, inlets and outlets to make sure they are functioning properly. Check troughs and tanks for leaks or cracks and repair or replace immediately, if necessary. Make certain the area adjacent to the trough is well protected with gravel, paving, or good cover. Be sure that the outlet pipe has a free outlet and is not causing any serious erosion problems. Check periodically to see if debris has fallen into the trough or tank which may restrict inflow or planned functions of the outflow system. Clean the entire system periodically and remove moss, algae growth, and/or sludge. Chemicals such as copper sulfate and chlorine can be used to prevent moss and algae growth. Local rules and regulations are to be followed when using chemicals to make sure they are safe for animals. Where necessary maintain coverings and insulation to prevent damage by freezing. Eradicate or otherwise remove all rodents or burrowing animals. Immediately repair any damage caused by their activity. Immediately repair any vandalism, vehicular or livestock damage. PIPELINESFlush pipelines used for liquid waste applications with clean water following waste application, or as needed, to prevent particle buildup. Drain the pipeline and components in areas that are subject to freezing. If parts of the pipeline cannot be drained, a non-toxic antifreeze solution may be added. Check to make sure all valves and air vents are set at the proper operating condition so they can provide protection to the pipeline. Inspect pipelines for signs of failure. Inspect risers and valves periodically for leaks or worn gaskets. Repair or replace pipeline, risers and valves as needed. Eradicate or otherwise remove all rodents or burrowing animals. Immediately repair any damage caused by their activity. Jo L Averill Farms AWMP Page 2-6 Section 2 PRODUCTION AREA PUMPSOperate and maintain pumps in accordance with good judgment and manufacture’s manuals and recommendations. Drain liquid manure from pumps during cold weather to prevent freezing. If parts of the system cannot be drained, a non-toxic antifreeze solution may be added. Inspect pumps periodically and remove debris wrapped around shafts and impellers. Maintain foot valves and check valves for proper operation. For proper operation of electric motors and controls, maintain lubrication for all bearings, keep electric panel free from obstructions and debris. Maintain electrical safety devices, assure all electrical contacts are tight, and lock main electrical switch to “OFF” position during non-use season. Maintain adequate shade and ventilation for pump motors. For proper operation of pumps, maintain lubrication for all bearings and pump shafts, assure belts are adjusted properly, maintain safety covering devices on open shafts and belt drives, check to make sure all safety valves and devices are set at proper operating conditions so they may provide protection to the pump and power unit. For centrifugal pumps, periodically measure tolerance between pump impeller and pump casing (i.e. wearing) and replace wear ring as needed to help restore new pump operating characteristics. Use portable pressure gauge (preferably a liquid filled gauge) to monitor pump performance. Operate and maintain agitators in accordance with the manufacture’s manual and recommendations. Inspect all plumbing annually as a minimum. Replace, tighten, or repair broken or loose connections and lines as needed. SOLID/LIQUID SEPARATION FACILITYInspect the solid/liquid separation facility daily to ensure the facility is operating properly and there has been no damage to structural components. Clean screens and outlets if they have become clogged or their capacity is not adequate for proper operation of the facility. Inspect the capacity of settling basins daily to ensure adequate capacity is available for Prevent any spillage or leakage onto roadways when transferring solids from the solid/liquid separation facility to the solids storage facilities and to utilization areas. Jo L Averill Farms AWMP Page 2-7 Section 2 PRODUCTION AREA WELL(S)Protect the area immediately surrounding the well from being damaged by agriculture machinery, vehicles, or livestock. All fences, railings, and/or warning signs shall be maintained to provide warning and/or prevent unauthorized human or livestock entry. Do not allow any foreign debris to accumulate and maintain soil and vegetative covering in the immediate vicinity of the well. Eradicate or otherwise remove all rodents or burrowing animals. Immediately repair any damage caused by their activity. Check metal surfaces for rust and other damage especially sections in contact with earthfill and with other materials. Repair or replace damaged section and apply paint as a protective covering. Keep all surface water from entering or accumulating at the immediate vicinity of the well site. Immediately repair any vandalism, vehicular, or livestock damage. CHEMICAL HANDLING CHECKLISTThe following measures shall be taken to prevent chemicals from contaminating process water or storm water storage and treatment systems: 1. Make sure all chemicals are stored in proper containers. Expired chemicals and empty containers are to be properly disposed of in accordance with state and federal regulations. Pesticides and associate refuse are to be disposed of in accordance with the FIFRA label. 2. Chemical storage areas are to be self-contained with no drains or other pathways that will allow spilled chemicals to exit the storage area. 3. Chemical storage areas are to be covered to prevent chemical contact with rain or snow. 4. Emergency procedures and equipment are to be in place to contain and clean up chemical spills. 5. Chemical handling and equipment wash areas are to be designed and constructed to prevent contamination of surface waters, waste water, and storm water storage and treatment systems.

Yield data and nutrient utilization rates for the crops grown are also shown on the inventory worksheet in ORAWM located in Section 5. Irrigated and nonirrigated crop yield data from the Tillamook County Soil Survey referenced in Section 5 indicates the yield data used in developing this plan is within the range of the given crop yields for well managed fields. Traveling big gun irrigation systems are also used to irrigate and apply wastewater containing manure and other organics produced from the Jo L Averill Farms. These systems use single large sprinkler nozzles usually mounted on a cart with wheels that is attached to a high density polyethylene pipeline that is rolled up on a large reel that provides a constant travel speed for the sprinkler. These systems apply water depending on the nozzle size, operating pressure and travel used and have an efficiency of 65 to 75 percent. Traveling big gun sprinkler systems must be well managed to prevent excess percolation, surface runoff, wind drift and evaporation losses. Other types of irrigation systems will be used to irrigate the crops that must be well managed to prevent excess percolation, surface runoff and erosion, wind drift and evaporation losses. The amount of irrigation water to apply based on the net irrigation requirements for the crop being grown can be found in the tables starting on page 3-42.

No application of wastewater or solids containing manure is to be made to the field buffer areas shown on the Setback Map on page 3-11. Applications of wastewater and solids containing manure should be made in accordance with guidance starting on page 3-8 to reduce the risk of contaminated runoff to surface water sources and leaching of contaminants to ground water sources. The phosphorus runoff rating for each of the farm fields is based on the Western Oregon Phosphorus Index and is shown in the table on page 4-73. Wastewater, solids and commercial fertilizer for any field with a high runoff rating must be applied on a phosphorus basis. Wastewater, solids and commercial fertilizer for any field with a low or medium runoff rating can be applied on a nitrogen basis. No applications manure or commercial fertilizer containing phosphorus are to be made on a field with a very high phosphorus runoff rating. GENERAL CONSIDERATIONS FOR MAKING MANURE APPLICATIONS Manure applications may be made at any time of the year provided certain factors have been considered. However, the overriding factor one should use in considering whether or not to apply nutrients to a crop, irrespective of the nutrient source, is the agronomic need of the crop at the time of application. The following guidelines are to be considered once the decision has been made to make a manure application.  Manure applications may commence once T-Sum 200 has been reached for the calendar year as long as you can comply with all other permit and AWMP requirements. Calculations for T-Sum 200 are outlined in OSU Extension Fertilizer Guide for Pastures (OSU FG63, 2000). T-Sum 200 is based on accumulated heat units and is an accurate guide to estimate plant activity. Research has shown that TSum 200 is the earliest date when plant roots begin to grow in the spring and thus are receptive to applied nutrients. Surface air temperature is monitored and the daily minimum and maximum air temperatures are summed and divided by two to get the average daily air temperature then converted to centigrade (F degrees minus 32 times 0.556). Manure applications may begin once 200 heat units have been accumulated. The average date of T-Sum 200 for Jo L Averill Farms is February 12th for the 30 year average from 1981-2010. However, one must still apply manure at agronomic rates based on the estimated growth potential of the crop and anticipated climatic events. Based on crop nutrient uptake patterns, manure applications should stop when the crop is done growing for the year and before the first significant rainfall event that is expected to result in saturated soils or surface runoff. Jo L Averill Farms AWMP Page 3-8 Section 3 UTILIZATION AREA  Fields that are subsurface (TILE) drained require additional precautions when manure is applied. Any pre-application tillage should leave as much residue as possible on the soil surface. Water control structures installed in subsurface drainage systems should be managed to prevent discharge of manure and wastewater during periods of application.  Be aware of the location of sensitive areas, concerns of neighbors or concerns of the public, which require special application procedures. To reduce odor problems, apply wastewater and solids containing manure in mid-morning when temperatures are warming and air is rising rather than in the afternoon or evening when air is cooling and settling. Avoid applications during periods of fog.  Calibrate application equipment to insure uniform distribution and accurate application rates in accordance with guidance given in the Considerations for Manure Applications starting on page 3-10. Refer to page 3-27 for guidance on the calibration of application equipment.  Maintain setbacks for manure application from any surface waters. The management goal is to allow no manure to enter surface waters at any time. The following table shows minimum setback requirements for manure applications: Season Manure type Liquid Liquid Solid Application Equipment Big gun Tank Wagon Spreader Wet Dry 75 feet 75 feet 35 feet 35 feet 10 feet 10 feet Note: a. Setbacks are the distance between open waterways and manure application area. b. Setback requirements will generally increase for manures which are applied aerially (such as a traveling big gun) versus manures applied lower to the ground (such as a splash bar) due to potential for drift from wind or splashing.  Record applications, transfers or exports of nutrients (manure and fertilizer) and maintain them for at least 5 years. The CAFO Recordkeeping Calendar or the tools and forms referenced in Section 5 may be used to record this information. Jo L Averill Farms AWMP Page 3-9 Section 3 UTILIZATION AREA CONSIDERATIONS FOR DRY SEASON MANURE APPLICATIONS: Apply wastewater and solids containing manure at agronomic rates shown on the table on page 3-31 using the following guidelines:  Consider using T-Sum 200 as a guideline to begin making manure applications.  Apply to land being prepared for crops and till manure into soil within 3 days of application if possible or apply to actively growing crops such as grass, clover or alfalfa.  Do not apply during rainfall events that are expected to result in saturated soils or surface runoff.  Maintain the setback buffer distances described on page 3-9 and shown on the Setback Map on page 3-11 when making applications of liquids or solids containing manure.  Record applications, transfers or exports of nutrients (manure and fertilizer) and maintain them for at least 5 years. The CAFO Recordkeeping Calendar or the tools and forms referenced in Section 5 may be used to record this information.

Call the ODA CAFO Program at (503) 986-4700 for guidance if a manure application is needed and the following guidelines CAN NOT be met:  Apply manure only to actively growing crops such as grass, clover or alfalfa.  Minimize application rates by using the maximum travel rates for the application equipment.  Maintain the setback buffer distances described in the table on page 3-9 and shown on the Setback Map on page 3-11 when making applications of liquids or solids containing manure.  Do not apply during rainfall events that are expected to result in saturated soils or surface runoff.  Do not apply to saturated or flooded soils. It is recommended that application(s) be limited to soils (areas) where the flooding frequency class rating is None, Very Rare or Rare.  Do not apply to slopes greater than 5%. See the Soil Map in Section 4 for the location of soil map units with slopes greater than 5%.  Applications of wastewater or solids containing manure to frozen soils should be avoided. Do the following if an application of wastewater or solids containing manure is to be made to frozen soils: - Apply only enough wastewater or solids containing manure to address storage limitations until suitable soil conditions for application are available. - Minimize applications to 5 wet tons per acre or less of solids containing manure and 6,788 gallons (0.25 inches) per acre or less of wastewater. - Apply to alternating strips to reduce the risk of contaminated runoff reaching surface water sources. - Apply to fields of established hay, pasture or fields containing at least 90% cover and are the furthest from open water sources. - Do not apply wastewater or solids containing manure within 200 feet of surface water sources, drainageways, wells, or inlets to subsurface drainage systems. - Runoff control systems such as earthen dikes must be in place where applications will be made to fields with slopes greater than 5%.  Record applications, transfers or exports of nutrients (manure and fertilizer) and maintain them for at least 5 years. The CAFO Recordkeeping Calendar or the tools and forms referenced in Section 5 may be used to record this information.  Do not apply manure or commercial fertilizer to fields receiving applications unless the nutrients applied in the manure are less than the annual application of nutrients planned in the nutrient budget for the fields. Jo L Averill Farms AWMP Page 3-17 Section 3 UTILIZATION AREA MANURE AND SOIL SAMPLING FREQUENCY Sample liquids and solids containing manure during applications in early spring annually and have each sample analyzed for Total Nitrogen (TKN), Ammonium Nitrogen (NH 4-N), Phosphorus (P) and Potassium (K) plus percent moisture. Ask the lab to report results in pounds per ton for the solids containing manure and in pounds per thousand gallons for liquids containing manure. Analyses of solids and liquids containing manure should be performed by a laboratory that meets the requirements and performance standards of the Manure Testing Laboratory Certification Program (MTLCP), http://www.mda.state.mn.us/licensing/pestfert/manurelabs.htm. Collect soil samples from all fields receiving solids or liquids containing manure within a 5 year period in the fall (September 15-October 15) in accordance with Pacific Northwest (PNW) Extension publication 570-E, “Monitoring Soil Nutrients Using a Management Unit Approach” referenced in Section 5. Have the soil samples analyzed for Total Nitrogen (TKN) and Phosphorus (P) and ask the lab to report results in parts per million (ppm). Soil test analyses should be performed by laboratories that meet the requirements and performance standards of the North American Proficiency Testing Program (NAPT) Proficiency Assessment Program (PAP); http://www.naptprogram.org/pap/. HOW TO SAMPLE LIQUID MANURE Obtain a composite following one of the procedures listed below and thoroughly mix. Using a plunger, an up-and-down action works well for mixing liquid manure in a five-gallon bucket. Fill a one-quart plastic bottle not more than three-quarters full with the composite sample. Store sample in freezer if not delivered to the lab immediately. Procedure 1. Sampling from storage- Agitate storage facility thoroughly before sampling. Collect at least five samples from the storage facility or during loading using a five-gallon bucket. Place a sub sample of the composite sample in a one-quart plastic container. Sampling a liquid manure storage facility without proper agitation (2-4 hrs. minimum) is not recommended due to nutrient stratification, which occurs in liquid systems. If manure is sampled from a lagoon that was not properly agitated, typically the nitrogen and potassium will be more concentrated in the top liquid, while the phosphorus will be more concentrated in the bottom solids. Procedure 2. Sampling during application- Place buckets around field to catch manure from spreader or irrigation equipment. Combine and mix samples into one composite sub sample in a one-quart plastic container. HOW TO SAMPLE SOLID MANURE Collect a composite sample by following one of the procedures listed below. A method for mixing a composite sample is to pile the manure and then shovel from the outside to the inside of the pile until well mixed. Fill a one-gallon plastic heavy-duty zip lock bag approximately one-half full with the composite sample, squeeze out excess air, close and seal. Store sample in freezer if not delivered to the laboratory immediately. Procedure 1. Sampling while loading - Recommended method for sampling from a stack or bedded pack. Take at least ten samples while loading several spreader loads and combine to form one composite sample. Thoroughly mix the composite sample and take Jo L Averill Farms AWMP Page 3-18 Section 3 UTILIZATION AREA an approximately one pound sub sample using a one-gallon plastic bag. Sampling directly from a stack or bedded pack is not recommended. Procedure 2. Sampling during spreading - Spread a tarp in field and catch the manure from one pass. Sample from several locations and create a composite sample. Thoroughly mix the composite sample together and take a one-pound sub sample using a one-gallon plastic bag. Procedure 3. Sampling daily haul - Place a five-gallon bucket under the barn cleaner 4-5 times while loading a spreader. Thoroughly mix the composite sample together and take a one-pound sub sample using a one-gallon plastic bag. Repeat sampling 2-3 times over a period of time and test separately to determine variability. Procedure 4. Sampling poultry in-house - Collect 8-10 samples from throughout the house to the depth the litter will be removed. Samples near feeders and waterers may not be indicative of the entire house and sub samples taken near here should be proportionate to their space occupied in the whole house. Mix the samples well in a five-gallon pail and take a one-pound sub sample, place it in a one-gallon zip lock bag. Procedure 5. Sampling stockpiled litter - Take ten sub samples from different locations around the pile at least 18 inches below the surface. Mix in a five-gallon pail and place a one-pound composite sample in a gallon zip lock bag. Sample Identification and Delivery Identify the sample container with information regarding the farm, animal species and date. This information should also be included on the sample information sheet along with application method, which is important in determining first year availability of nitrogen. Keep all manure samples frozen until shipped or delivered to a laboratory. Ship early in the week (Mon.-Wed.) and avoid holidays and weekends.

Manure should be analyzed annually for a minimum of three (3) consecutive years to develop a cumulative manure analysis history as a basis for nutrient allocation to the fields. Jo L Averill Farms AWMP Page 3-21 Section 3 TILIZA TION AREA Jo Averill Farms AWMP Page 3?22 Section 3 UTILIZATION AREA HOW TO SAMPLE SOILS Current soil tests must be used in the development and editing of nutrient management plans. A current soil test is one that is no older than 5 years that is used to represent the nutrient status of the entire field. Soil analysis must be performed by laboratories successfully meeting the requirements and performance standards of the North American Proficiency Testing Program-Performance Assessment Program (NAPT-PAP). Results of these analysis will be used to determine application rates for manure, litter, and process wastewater. Guidance for soil sampling can be found in the Pacific Northwest (PNW) Extension publication 570-E, “Monitoring Soil Nutrients Using a Management Unit Approach”. Oregon State university Extension publication EC1478, “Soil Test interpretation Guide” provides guidance on how to determine soil nutrient concentrations and how to adjust soil pH to improve nutrient availability. Field Area. A composite soil sample should represent a uniform field area. Each area should have similar crop and fertility history. Soil characteristics (color, slope, texture, drainage) should be similar. Exclude small areas within a field that are obviously different. The field area represented by a single composite sample should represent no more than 40 irrigated acres or 100 dry land acres. Sampling Depth. Laboratory tests are calibrated to specific depths. It is vital to collect samples from appropriate depths. Sampling depth for most soils is the rooting depth in 6inch intervals. In Oregon, as a minimum, soil samples should be collected from the 0-12” depth and from the 12-24” depth. The 0-6” surface soil samples are normally used for conventional tests of organic matter, nitrogen, phosphorus, potassium, pH and salt levels. Additionally, subsurface samples from the 6-24” depth are needed to estimate nitrogen availability for crops. Post Harvest Soil Testing for Evaluating Nutrient Applications. Refer to Pacific Northwest (PNW) Extension publication 570-E, “Monitoring Soil Nutrients Using a Management Unit Approach” in Section 5 for guidance on how to evaluate nutrient applications and crop uptake of nutrients.

Calibration should be completed at least annually to insure manure and fertilizer will be uniformly applied. There are two basic approaches for calibrating a manure spreader – the load area and the weight area methods. The load area method is more accurate and can be used for both liquid and solid manure. The weight area method works only with solid or semi-solid manure. Irrigation System Calibration Place 3-5 buckets throughout the irrigation spray pattern and collect samples while operating the pump at a given rpm and pressure (for a traveling gun record the travel speed also). At the end of the planned sample period measure the amount of liquid collected in inches (average the samples). The following chart shows how many gallons per acre applied per inch of liquid applied: Inches Liquid Manure Applied via Irrigation: 0.20 0.30 0.40 0.50 0.75 1.00 1.25 1.50 Gallons per Acre: 5,431 8,146 10,862 13,577 20,366 27,154 33,943 40,731 Soft Hose Injection System with Irrigation Hose: Alternative 1. Use a flow meter mounted on the injector system and calculate the distance and width to determine amount applied over a measured area. Example the flow meter measures 1,000 gallons over a distance of 600 feet and 10 feet wide. Formula: Application Rate (7,260 gallons/acre) = (Gallons Applied (1,000 gal) X 43,560 sq. ft/acre) divided by (Distance traveled (600 ft) X Application width (10 ft)) Alternative 2. (Requires a 10-20 gallon graduated measuring container) Step 1) In the field, measure the flow out of one injector for 5 seconds into the graduated measuring container and record gallons, repeat three (3) times and average the results. Step 2) Multiply the average amount collected from one injector by the number of injectors (equals amount applied for the whole system for 5 seconds). Step 3) Multiply the results of Step 2 times 12 to get gallons per minute. Step 4) Place the injector in the soil at the planned depth and operating speed and record the distance traveled in 1 minute (average 3 different measurements). Step 5) Determine the effective application width (number of injectors X injector spacing in feet). Jo L Averill Farms AWMP Page 3-27 Section 3 UTILIZATION AREA Step 6) Multiply the effective width times the distance traveled in 1 minute (this gives the square feet covered in 1 minute). Step 7) Divide the result of Step 6 by 43,560 (this gives the acres covered in 1 minute). Step 8) Divide the results of Step 3 (gallons per minute) by the results of Step 7 (acres covered in 1 minute) - (this gives the gallons applied per acre. For example: Step 1) Collect an average of 6 gallons from one injector for 5 seconds. Step 2) Applicator has 8 injectors (8 injectors X 6 gallons per injector = 48 gallons for 5 seconds) Step 3) 48 gallons in 5 seconds X 12 = 576 gallons/minute applied Step 4) Average distance covered in 1 minute was 250 feet Step 5) Average width of the applicator is 12 feet. Step 6) 12 feet wide X 250 feet long = 3000 square feet Step 7) 3000 square feet divided by 43,560 square feet/acre = .0688 acres covered in 1 minute Step 8) 576 gallons/minute divided by .0688 acres/minute = 8,372 gallons/acre. Manure Spreader/Tanker Calibration There are several methods that can be used to calibrate the application rate of a manure spreader. The two best methods are the load-area method and the weight-area method. It is desirable to repeat the calibration procedure 2 to 3 times and average the results to establish a more accurate calibration. Before calibrating a manure spreader, the spreader settings such as splash plates should be adjusted so that the spread is uniform. Most spreaders tend to deposit more manure near the middle than at the edge of the spread pattern. Overlapping can make the overall application more uniform. Calibrating application rates when overlapping is involved requires measuring the width of two spreads and dividing by two to get the effective spread width. Calibration should take place annually or whenever manure is being applied from a different source or consistency. Jo L Averill Farms AWMP Page 3-28 Section 3 UTILIZATION AREA Load-Area Method: The load-area method is the most accurate and can be used for both liquid and soild manure. The load area method is a 3-step process: Step 1) Determine the amount of manure in the spreader. The most accurate way to determine the amount of manure in a spreader is weighting the spreader when it is empty and again when it is full. For a reliable estimate of spreader capacity, weigh several representative loads (at least five) to determine the average gross weight. Subtract the empty spreader weight. Then, calculate the average net loaded weight. Step 2) Determine the area of spread using the method at the right. Width measurements near the beginning and end of the spread pattern should be avoided because the spreader may not be operating at full capacity. Step 3) Calculate the application rate. The application rate is calculated using the formula for either liquid or solid manure. Formula for Solid Manure Equals Tons/Acre (Average Loaded Weight (lbs) x 21.81) divided by (Distance Traveled (ft) x Width of Spread (ft)) Formula for Liquid Manure Equals Gal/Acre (Tank Volume (gal) x 43,560) divided by (Distance Traveled (ft) x Width of Spread (ft)) Weight-Area Method: The weight-area method can only be used with solid or semi-solid manure. When a scale is not available, the application rate of a box spreader can be determined by collecting manure on a tarp or piece of heavy material. The weight area method is less accurate than the load area method. This method consists of eight steps: Step 1) Prepare/cut three 56-inch square tarps or pieces of heavy material (this size equals 1/2,000 of an acre). The pounds of manure collected on 56 inches square equals tons applied per acre. Step 2) Weigh one of the clean tarps and a large bucket on a platform scale. Record the weight. Step 3) Anchor the three tarps in the field ahead of the spreader near the beginning, middle, and end of the area that will be spread with one load. Step 4) Drive over the three tarps at a normal speed to collect a representative manure sample. Step 5) Fold and place the first tarp into the empty bucket without spilling the manure. Weigh the bucket, tarp, and manure. Subtract the weight of the clean tarp and bucket recorded in step 2. Jo L Averill Farms AWMP Page 3-29 Section 3 UTILIZATION AREA Step 6) Repeat the process for each of the two remaining tarps. Calculate the average weight (pounds) of the manure collected. This value equals tons of manure applied per acre. Factor for converting pounds to tons and square feet to acres (21.8 = 43,560 sq ft per acre divided by 2,000 lbs/ton). The factor for converting square feet to acres = 43,560 sq ft per acre. Step 7) Determining Area of Spread. The “area of spread” is the length and width of the ground covered with one load of manure. The area of spread is affected by speed and equipment settings. Spreaders discharge manure at varying rates depending on travel and PTO speed, gear box settings, and discharge openings. It is important to adjust the spreader so the pattern is as uniform as possible. Accurately measuring the length and width of this area is essential. To determine width, measure two adjacent spreads and divide by two to find the “effective” spread width. This accounts for overlap, which is often needed for a more uniform application. The length of spread is determined using the following three values: 1. Desired manure application rate based on soil and manure tests, 2. Width of the manure spread, and 3. Manure spreader holding capacity (weight and/or volume). From these values, calculate the distance or lengths of spread using these formulas: Formula: Solid Manure Equals Feet/Load (Average Load Weight (lbs) x 21.81) divided by (Spread Width (ft) x App. Rate (tons/ac)) Formula: Liquid Manure Equals Feet/Load (Tank Volume (gal) x 43,560) divided by (Spread Width (ft) x Desired App. Rate (gal/ac)) Step 8) Spread a load. If the distance traveled does not equal the calculated distance, adjust the speed or equipment settings.

The formulas for determining the total nutrient application rate per unit yield for each crop shown in the table below are as follows: Total N to apply in pounds = N in pounds per yield unit from the table for the crop grown X percent (%) dry matter (DM) of harvested crop/100 X planned or measured yield per yield unit Total P2O5 to apply in pounds = P in pounds per yield unit from the table for the crop grown X 2.291 P2O5/P X percent (%) dry matter (DM) of harvested crop/100 X planned or measured yield per yield unit Total K2O to apply in pounds = K in pounds per yield unit from the table for the crop grown X 1.205 K2O/K X percent (%) dry matter (DM) of harvested crop/100 X planned or measured yield per yield unit The following table shows the crops that may be grown on this farm:

to the irrigated fields as shown on the Field Map will manage soil moisture to promote the desired crop response, optimize the available water supplies, minimize irrigation induced erosion, decrease non-point source pollution of surface and groundwater sources, manage salts in the crop root zone and manage the crop micro climate. Irrigation water is supplied by wells and surface water sources using pumps through an underground pvc pipelines to sprinkler irrigation systems. The average amount of irrigation water to be applied per application and total annual amount needed for irrigated crops with guidance on when and how much irrigation water to apply can be found starting on page 3-42. Permits: Under Oregon law all water is publicly owned and anyone planning to store or divert surface or groundwater for the purpose of irrigation must obtain a permit or water right from the Oregon Water Resources Department. These permits or water rights must be obtained prior to the use of the water. It is the responsibility of the Farmer to file for the necessary permits or water rights. Permits or water rights are not needed to apply wastewater as a nutrient source.

The map unit descriptions in this report, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. All the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of a given series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. Jo L Averill Farms AWMP Page 4-3 Section 4 SOIL AND RISK ASSESSMENT The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. Additional information about the map units described in this report is available in other soil reports, which give properties of the soils and the limitations, capabilities, and potentials for many uses. Also, the narratives that accompany the soil reports define some of the properties included in the map unit descriptions.

The map unit descriptions in this report, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. All the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of a given series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. Jo L Averill Farms AWMP Page 4-25 Section 4 SOIL AND RISK ASSESSMENT An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. Additional information about the map units described in this report is available in other soil reports, which give properties of the soils and the limitations, capabilities, and potentials for many uses. Also, the narratives that accompany the soil reports define some of the properties included in the map unit descriptions.

The map unit descriptions in this report, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. All the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of a given series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. Jo L Averill Farms AWMP Page 4-37 Section 4 SOIL AND RISK ASSESSMENT The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. Additional information about the map units described in this report is available in other soil reports, which give properties of the soils and the limitations, capabilities, and potentials for many uses. Also, the narratives that accompany the soil reports define some of the properties included in the map unit descriptions.

There is a low probability of an adverse impact to surface waters from P losses on this site. Soil test P and P losses are likely to increase in future due to Nbased nutrient management from animal manure. Nitrogen Medium potential for P movement from this site given current management practices and site characteristics. Practices should be introduced to reduce P losses by surface runoff, subsurface flow, and erosion. Soil test P and P losses are likely to increase in future due to Nbased nutrient management from animal manure. Nitrogen High potential for P movement from this site given current management practices and site characteristics. All practicable management practices to reduce P losses through surface runoff, subsurface flow, or erosion should be implemented. Phosphorus Very high potential for P movement from this site given current management practices and site characteristics. Active remediation techniques should be implemented in an effort to reduce the P loss potential from this site.

Section 5 REFERENCES Land Application Area: Storm water runo?? ?'om the land application area is not considered a prohibited discharge and is allowed if the land is being managed in compliance with the AWMP approved by ODA. The permit requires that each permitted operation have a current AWMP approved by ODA. An AWMP describes how a CAFO is managed with respect to containment, treatment, storage, and utilization of manure, litter, and process wastewater in order to remain in compliance with permit conditions and water quality laws. The AWMP must accurately represent current land base, manure storage, herd/?ock size, and current management practices used at the livestock operation. The AWMP must re?ect production practices and be implemented accordingly. You must provide adequate storage capacity for solid and liquid wastes at all times so that land application occurs only during periods when soil and weather conditions are suitable. Monitoring, recordkeeping and reporting of waste applications, and inspection requirements must occur as described in an AWMP approved by ODA and requirements in section S4. of the permit. Note: Large concentrated CA 0s have additional requirements. You must apply manure. litter and process wastes to lands at agronomic rates in accordance with proper agricultural practices and as speci?ed in a waste management plan that has been approved by ODA. Waste applications must not exceed the capacity of the soil and crops to assimilate nutrients and minim izc water pollution, must be quanti?able, and based on the NRCS Phosphorous Index, Agronomy Technical Note #26, revised June 2008, and must account for all other nitrogen and phosphorus. Prohibitions: If discharge to surface water or groundwater will result, application to ?ooded and saturated land is prohibited. Proposed waste and waste water application to frozen soil must be included in an AWMP. Land application of wastes or waste water during rainfall events that are expected to result in saturated soils or surface runoff is prohibited.
