All of the animals on Pozzi Dairy 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. Manure, bedding and wasted feed collected on the alleyways of the livestock barns for Pozzi Dairy are scraped to below ground collection tanks (BGCT) shown on the Production Area Map for the dairy on page 2-9. Some of the manure, bedding and wasted feed collected in the livestock barns is collected and directly transferred to the solids storage area (SSA). Wastewater from the holding pen and milking facility is transferred to a below ground collection tank by gravity flow through underground pipelines. Any rainfall runoff from paved areas containing manure and the solids storage area drain to the collection tanks. Wastewater stored in the underground collection tanks is pumped through a pipeline to an above ground collection tank (AGCT). Wastewater is pumped from the above ground collection tank to a solid/liquid separation facility. Wastewater from the solid/liquid separation facility drains by pipeline to the above ground storage tank (AGST) shown on the Production Area Map on page 2-9. Wastewater from the above ground storage tank will be pumped to the reinforced concrete lagoons (RCL1 & RCL2) shown on the Production Area Map on page 2-9 when they are competed for long term storage. The solids cleaned from the livestock barns and from the solid/liquid separation facility are stored on an unroofed concrete slab area (SSA) and planned solids storage area shown on the Production Area Map for the dairy on page 2-9. Approximately 30 percent of the solids are applied on farm with a tractor pulled spreader and the other 70 percent are transferred to the heifer feeding facility on the Fort Rock Ranch owned by the LaFranchi family. Wastewater stored in the storage tank and lagoon are applied to the hay and pasture land fields during the spring and summer months to utilize the nutrients and organics. Wastewater is applied using traveling big gun sprinkler system and tractor pulled tank wagon. The wastewater and solids from the storage facilities will be applied to the hay and pasture land fields owned by Pozzi Dairy by employees of the dairy or members of the LaFranchi family to be used as a nutrient source. Pozzi Dairy AWMP Page 1-3 Section 1 GENERAL INFORMATION Mortalities that occur during the year on the Pozzi Dairy are buried or transferred to the West Coast Game Park Safari in Bandon, Oregon to be used as feed for the animals housed there. Pozzi Dairy owns 493.9 contiguous acres for the dairy farm facilities described above and the hay and pasture land fields used to produce forage for the dairy livestock. The dairy farm facilities, shops and houses consist of 28.9 acres and the irrigated hay and pasture land consists of 465.0 acres used to produce forage for the dairy livestock. The crop rotation for the Pozzi Dairy consists of 5 to 7 years of perennial grass that is harvested by grazing livestock and for hay. The estimated yields for the irrigated grass harvested by grazing livestock and as hay is 6.5 tons per acre of dry matter. The Fort Rock Ranch has 1,638.5 contiguous acres for the feedlot, headquarters and center pivots used to grow alfalfa, triticale and barley for hay in a 5 to 7 year rotation. The feedlot, shops and houses consist of 52.1 acres and the irrigated alfalfa, triticale and barley consists of 1,586.4 acres used to produce hay. The estimated yields for the irrigated alfalfa is 5 tons per acre of dry matter and the estimated yield for the triticale and barley is 5 tons per acre of dry matter. The soil concentration of phosphorus is very low in the Pozzi Dairy hay and pasture land fields and the Fort Rock Ranch hay fields. Applications of wastewater and solids containing manure are planned on a nitrogen basis on all of the Pozzi Dairy fields and the soil phosphorus concentrations will be monitored using soil tests. Only applications of and solids containing manure are planned on a nitrogen basis for the Fort Rock Ranch fields and the soil phosphorus concentrations will be monitored using soil tests. It is estimated that enough manure is produced to meet the nutrient demand for the Pozzi Dairy hay and pasture land fields but not the Fort Rock Ranch hay fields. Supplemental nutrient applications to the Pozzi Dairy hay and pasture land fields and Fort Rock Ranch hay fields should be based on soil tests and fertilizer guides to prevent excess soil nutrient concentrations.

The planned number of animals for Pozzi Dairy is 1,550 dairy animals consisting of 1,200 milk cows, 150 dry cows, 100 heifers, and 100 calves. A request for modifying the permitted animal numbers for Pozzi Dairy is location in Section 5. This plan was written based on the 1,550 animals and land base described herein. ANIMAL MORTALITY MANAGEMENT Currently animal mortalities for the Pozzi Dairy are being disposed of by burial or transferred to the West Coast Game Park Safari in Bandon, Oregon for use as wild animal feed. Other methods of dealing with mortalities may be employed by Pozzi Dairy 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 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. Flushwater used to clean the alleyways in the barns is directed to catch basins that drain to the wastewater collection facilities via underground pipelines. Flushwater is recycled from the main waste storage facility during the fall and winter storage period so there is no additional fresh water added. Leachate and rainfall runoff from the solids storage area drain to wastewater collection tank. The estimated volumes of leachate and rainfall runoff from the silage and solid storage areas that will be collected annually were 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 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 away from areas containing animal manure. All process water from the dairy operation is directed to collection tanks. The estimated volume of process water that will be collected annually was generated using the ORAWM workbook located in Section 5. Pozzi Dairy AWMP Page 2-1 Section 2 PRODUCTION AREA TREATMENT FACILITIES A solid/liquid separator will be used to separate solids from the wastewater produced from this operation. Improvements to the solid/liquid separation system are planned for the future. STORAGE FACILITIES The underground reinforced concrete collection tanks (BGCT & AGCT) shown on the Production Area Map on page 2-9 are used to collect wastewater containing manure. These facilities are considered collection and temporary storage facilities only and their capacity was not included in the long term storage calculations. Capacities and estimate volumes to store for the waste storage facilities can be found on the storage worksheet in the ORAWM workbook located in Section 5. TRANSFER OF MANURE, PROCESS WATER AND RUNOFF Wastewater, manure, bedding and wasted feed from the livestock barns is directed to the collection tanks where it is pumped to the solid/liquid separation facility to separate solids from the wastewater. Wastewater from the solid/liquid separation facility is directed to an above ground wastewater storage tank and separated solids are transferred to the solids storage area shown on the Production Area Map on page 2-9. Wastewater stored in the wastewater storage facilities is pumped to the hay and pasture fields using underground pipelines to be utilized as a source of nutrients. Traveling big gun irrigation systems and a tractor pulled tank wagon are used to apply the wastewater to the hay and pasture land fields. Solids stored in the solids storage area are hauled to the hay and pasture land fields and applied using a tractor pulled solids spreader to be utilized as a source of nutrients. Approximately 30 percent of the solids containing manure are applied on the Pozzi Dairy hay and pasture land fields and 70 percent is transferred by truck to the Fort Rock Ranch hay fields. Pozzi Dairy AWMP Page 2-2 Section 2 PRODUCTION AREA OPERATION AND MAINTENANCE CONSIDERATIONS WASTEWATER COLLECTION AND STORAGE TANKS (BGCT, AGCT & AGST)The wastewater collection (BGCT & AGCT) and storage tanks (AGST) shown on the Production Area Map on page 2-9 are used to collect and store wastewater containing manure generated by the Pozzi Dairy. The storage capacity and estimated storage period for the above ground wastewater storage tank (AGST) are shown on the ORAWM workbook storage worksheet located in Section 5. Emptying of the above ground wastewater storage tank 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 above ground wastewater storage tank must be as empty as possible in the fall before the fall and winter rainy season begins. Any annual buildup of solids in the above ground wastewater storage tank 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 collection or storage facility. 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. Pozzi Dairy AWMP Page 2-3 Section 2 PRODUCTION AREA Do not assume any tank, including open top tanks, are well ventilated. REINFORCED CONCRETE LAGOONS (RCL1 & RCL2)The reinforced concrete lagoons (RCL1 & RCL2) shown on the Production Area Map on page 2-9 are used to store wastewater containing manure generated by the Pozzi Dairy. The storage capacity and estimated storage period for the reinforced concrete lagoons are shown on the ORAWM workbook storage worksheet for tanks located in Section 5. Emptying of the reinforced concrete lagoons 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 reinforced concrete lagoons must be as empty as possible in the fall before the fall and winter rainy season begins. Any annual sludge buildup in the reinforced concrete lagoons must be removed to maintain design capacity and applied to land application areas in accordance with guidance given in Section 3, Utilization Area. Inspect the reinforced concrete lagoons weekly to insure structural integrity and that at least 1 foot-6 inches of freeboard is being maintained to accommodate excess rainfall such as a 25 year-24hour storm and prevent overtopping the walls. If the structural integrity of a reinforced concrete lagoon wall is found to be compromised, immediately draw the liquid level down below the damaged area to determine the cause. Seek the services of a qualified engineer to assess the damage and recommend necessary repairs before allowing wastewater levels above the damaged area. Pump the reinforced concrete lagoons to the lowest level possible during the summer months and inspect the walls for structural damage. If structural damage to the wall of the reinforced concrete lagoon is discovered, seek the services of a qualified engineer to assess the damage and recommend necessary repairs before allowing wastewater levels above the damaged area. Follow the guidance given in Section 3, Utilization Area, when applying wastewater to fields. Do not permit livestock access to the reinforced concrete lagoons or on earth fills surrounding the lagoon. Control undesirable vegetation growth on earth fills by spraying or mowing. Control rodents as necessary. Check elevations of earth fills periodically and restored to grade and shape as necessary. Fill and reseed eroded earth fill areas or repair with suitable materials. Safety features such as signs and fences should be kept in good repair. Do not dispose of animal carcasses in any wastewater storage facility. It is against the law to do so. SOLIDS STORAGE AREA (SSA)The solids storage area (SSA) shown on the Production Area Map on page 2-9 is used to store solids containing manure generated by the Pozzi Dairy. The storage capacity and estimated storage period for the solids storage area are shown on the ORAWM workbook storage worksheet located in Section 5. Emptying of the solids storage area 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 Pozzi Dairy AWMP Page 2-4 Section 2 PRODUCTION AREA Section 3, Utilization Area. To function properly and have the greatest management flexibility, the solids storage area 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 area. 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. 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. 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. Pozzi Dairy AWMP Page 2-5 Section 2 PRODUCTION AREA 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. 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.

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 Coos 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 used to irrigate and apply wastewater containing manure and other organics produced from the Pozzi Dairy to the hay and pasture land fields. 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. Center pivot sprinkler irrigation systems are used to irrigate the Fort Rock Ranch hay land fields. These systems apply water depending on the sprinkler nozzle size and have an efficiency of 80 to 85 percent. These systems must be well managed to prevent excess percolation, surface runoff, wind drift and evaporation losses. If other types of irrigation systems will be used to irrigate the crops, they 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 3-35.

No application of wastewater or solids containing manure is to be made to the field setback areas shown on the Setback Map on page 3-9. Applications of wastewater and solids containing manure should be made in accordance with guidance starting on page 3-5 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 Eastern or Western Oregon Phosphorus Index and is shown in the table starting on page 4-33. 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 be done as long as you can comply with all permit conditions and can meet the conditions outlined on page 3-6 to 3-11 in the AWMP. 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.  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 3-6. Refer to page 3-21 for guidance on the calibration of application equipment. Pozzi Dairy AWMP Page 3-5 Section 3 UTILIZATION AREA  Maintain setbacks for manure application from any surface waters. The management goal is not to allow 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 35 feet 35 feet 35 feet 35 feet 35 feet 35 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. Pozzi Dairy AWMP Page 3-6 Section 3 TILIZA TION AREA Pozzi Dairy AWMP Page 3?7 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 3-25 using the following guidelines:  Apply to land being prepared for crops. Till manure into soil within 3 days of application if possible or apply to actively growing crops such as grass, clover or alfalfa after cutting.  Do not apply during rainfall events that are expected to result in saturated soils or surface runoff.  Maintain the setback distances described on page 3-6 and shown on the Setback Map on page 3-9 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.

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 distances described in the table on page 3-6 and shown on the Setback Map on page 3-9 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. Pozzi Dairy AWMP Page 3-11 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. Pozzi Dairy AWMP Page 3-12 Section 3 UTILIZATION AREA 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 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. Pozzi Dairy AWMP Page 3-15 Section 3 TILIZA TION AREA Pozzi Dairy AWMP Page 3-1 6 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.

Pozzi Dairy AWMP Page 3-20 Section 3 UTILIZATION AREA HOW TO CALIBRATE APPLICATION EQUIPMENT Calibration of application equipment is a critical part of nutrient management. 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). Pozzi Dairy AWMP Page 3-21 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. Pozzi Dairy AWMP Page 3-22 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. Pozzi Dairy AWMP Page 3-23 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. Pozzi Dairy AWMP Page 3-24 Section 3 UTILIZATION AREA AMOUNT OF MANURE TO APPLY FOR CROPS GROWN The timing and frequency of applications of wastewater and solids containing manure for utilization by crops shown in the table below are based on information provided in Oregon State University Extension publications listed in Section 5. 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:

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 3-35. 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.

Page 4?4 Section 4 Section 4 SOIL AND RISK ASSESSMENT SOIL REPORTS Map Unit Description The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. 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. Pozzi Dairy AWMP Page 4-5 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.

(See Table 1: CAFOs Requiring Permit Coverage.) 22. “Vegetative buffer” as defined at 40 CFR §412.4(b)(2) means a narrow, permanent strip of dense perennial vegetation established parallel to the contours of and perpendicular to the dominant slope of the field for the purposes of slowing water runoff, enhancing water infiltration, and minimizing the risk of any potential nutrients or pollutants from leaving the field and reaching surface waters. 23. “Wastes” is defined at ORS 468B.005(9). 24. “Waste storage facilities” means the physical system used for the isolation and retention of process wastes on the confined animal feeding operation until their ultimate utilization. 25. “Waste water control facility” means a “disposal system” or “treatment works” is defined at ORS 468B.005(8). 26. “Water” or “waters of the state” is defined at ORS 468B.005(10). 27. “Waters of the U.S.” is defined at 40 CFR §122.2. Pozzi Dairy AWMP CAFO NPDES General Permit #01-2009 Expiration Date: May 31, 2014 Page 5 of 24 SPECIAL CONDITIONS S1. PERMIT COVERAGE S1.A. When is a Permit Required? 1. Pursuant to ORS 468B.200, it is the policy of the State of Oregon to protect the quality of groundwater and surface waters of Oregon by preventing animal wastes from discharging into waters of the state. To implement this policy, ORS 468B.050(1)(d) requires that any person who owns or operates a confined animal feeding operation (CAFO) listed in S1.A.2 below obtain a permit from ODA and DEQ. As a result, there is no state process to certify that a CAFO does not discharge or propose to discharge to waters of the state and permit coverage is required regardless of discharge status. Coverage under this general permit is required for all CAFOs listed in S!.A.2 unless application is made for an individual permit or an individual permit is required by ODA and DEQ. 2. Any person who owns or operates a CAFO defined as follows is required by ORS 468B.050(1)(d) to obtain coverage under this permit (see Table 1 below for more detail): (a) State small confined animal feeding operation that confines animals for more than four (4) months and has a waste water control facility or disposal system for wet or dry wastes. (b) State medium confined animal feeding operation that confines animals for more than four (4) months and has a waste water control facility or disposal system for wet or dry wastes. (c) Small, medium, or large concentrated animal feeding operation defined in 40 CFR §122.23(b).

Coverage under this permit will be canceled upon the issuance of an individual permit. General Permit Coverage 1. Consistent with ORS 468B.200, ODA and DEQ developed this general permit to prohibit routine discharges of manure, litter, and process waste water from CAFO operations to waters of the state. Discharges of manure, litter, or process waste water to waters of the state are only expected to occur under extreme weather conditions and as limited by the conditions of this general permit. Further, the general permit only authorizes the discharge of pollutants resulting from the processes, wastes, and operations that have been clearly identified in the permittee’s AWMP approved by ODA. Pozzi Dairy AWMP 2. 3. S1.E. Except for any toxic effluent standards and prohibitions imposed under section 307 of the federal Clean Water Act (CWA) and groundwater protection requirements established under OAR 340-040, a permittee in compliance with this permit during its term is considered to be in compliance, for purposes of enforcement, with state water quality laws and relevant sections of the CWA, as provided in 40 CFR §122.5. The specific effect of permit compliance on enforcement authority is set out in OAR 340-045-0080. Request for Cancellation 1. Any permittee may request in writing to ODA that coverage under this permit be cancelled if: (a) Conditions or standards have changed so that the CAFO no longer qualifies for or is required to have coverage under this permit; or (b) The CAFO no longer has animals on site and all waste storage and control facilities have been decommissioned in accordance with Natural Resources Conservation Service (NRCS) conservation practice standard, code 360, entitled Closure of Waste Impoundments (Jan. 2006); and (c) The permittee certifies that it will not commence operation of a CAFO regulated by this permit at the same location without making a new application for registration under this general permit and is granted coverage or applies for and is issued an individual permit. 2. S1.F. CAFO NPDES General Permit #01-2009 Expiration Date: May 31, 2014 Page 7 of 24 This permit does not cover disposal of human wastes or waste water control systems that mix human and animal wastes. Any person owning or operating such a system must apply to DEQ for coverage under an individual or general permit issued pursuant to ORS 468B.050. This general permit for CAFOs may be used in addition to an individual or general permit issued by DEQ pursuant to ORS 468B.050. ODA will respond to the request for cancellation by conducting a site inspection and a review of the permittee’s file. ODA will notify the permittee in writing of termination of coverage under this permit or deny the request with an explanation of why the request was denied. Individual Permit Coverage 1. When appropriate, the director may require any person to obtain an individual permit pursuant to OAR 3400033(10). In such cases, the person will be notified in writing by the director. This written notice will include the reason why an individual permit is being required, an application form, the amount of the permit fee due at application, and application due date. 2.

DISCHARGE LIMITATIONS AND OPERATING REQUIREMENTS S2.A. Discharge Limitations The permittee is prohibited from discharging manure, litter, or process wastes to surface waters and groundwaters of the state, except as allowed in S2.B and S2.C and provided these discharges allowed in S2.B and S2.C do not cause or contribute to a violation of state water quality standards. Discharges to surface water due to upset or bypass are authorized only in accordance with applicable requirements in G16 Bypass [40 CFR §122.41(m)], p. 23 and G17 Upset [40 CFR §122.41(n)], p. 24. Types of discharge that are prohibited include but are not limited to: contaminated runoff from confinement or waste accumulation areas; overflow or discharges from waste storage facilities; discharges due to improper land application activities from surface drainages or field tile outlets, discharges due to equipment failure; or leakage or seepage from facilities in the production area in excess of approved designs. S2.B. S2.C. Production Area Limitations 1. For all small and medium confined animal feeding operations and small, medium, and large concentrated animal feeding operations, except new source swine, poultry, and veal large concentrated animal feeding operations: The permittee is prohibited from discharging manure, litter, or process waste water to surface waters of the state from the production area, except when: (a) Rainfall events cause an overflow of waste management and storage facilities designed, constructed, operated, and maintained to contain all manure, litter, and process waste waters including the contaminated runoff and direct precipitation from a 25-year, 24-hour rainfall event; and (b) The production area is operated in accordance with the applicable inspection, maintenance, recordkeeping, and reporting requirements of this permit. 2. For new source swine, poultry, and veal large concentrated feeding operations: The permittee is prohibited from discharging manure, litter, or process waste water to surface waters of the state. 3. The permittee must properly land apply or otherwise handle authorized discharges from the production area in a way that minimizes impacts on surface water or groundwater of the state and complies with state water quality standards. 4. The permittee must not exceed the seepage design rates approved by ODA for waste storage or animal confinement facilities and seepage to groundwater from these facilities must not violate state groundwater quality protection standards. Land Application Limitations 1. When applying manure, litter, and process waste water to lands, the permittee must apply at agronomic rates in accordance with the permittee’s ODA-approved AWMP. Land application areas include land under the control of the permittee, whether it is owned, rented, or leased, to which manure, litter, or process waste water from the production area is or may be applied. 2. The permittee’s discharges to groundwater due to seepage below the root zone of the crop or by other means must not violate state groundwater quality protection standards. 3. The permittee is allowed to apply manure, litter, or process waste water to frozen soil provided: (a) Its AWMP addresses such applications [see S3.C.3(j)]; (b) Discharge to surface waters and groundwaters of the state will not occur, except as allowed in S2.B and S2.C; and (c) Land applications do not cause or contribute to a violation of state water quality standards. Pozzi Dairy AWMP 4. CAFO NPDES General Permit #01-2009 Expiration Date: May 31, 2014 Page 10 of 24 The permittee is prohibited from applying manure, litter, or process waste water to saturated soils or during rainfall events that are expected to result in saturated soils or surface runoff. When such a application is a desired alternative to allowing waste storage or waste water control facilities to overflow (e.g., land application to saturated soils to pond waste water onsite provides for greater protection of surface waters than a direct overflow of a waste storage tank to surface waters), the land application will be considered an upset condition and the permittee must comply with the provisions of G17 Upset [40 CFR §122.41(n)], p. 24. S2.D. Direct Access by Animals to Surface Water in the Production Area Prohibited The permittee must prevent direct animal contact with surface waters of the state in the production area of its CAFO. Direct animal contact means any situation where animals in the production area have free access and are allowed to loiter or drop waste in surface waters. Direct contact with surface waters by animals on pasture or rangeland is not, by itself, a violation of this permit. S2.E. Waste Storage Facilities 1. The permittee 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 allow for agronomic application and are in compliance with the Land Application Limitations in Condition S2.C, p. 9 of this permit. S2.F. 2. The permittee must site, design, construct, operate, and maintain all waste storage facilities consistent with the AWMP. New and modified construction of waste facilities must be approved in advance and prior to construction by ODA in conformance with ORS 468B.055 and OARs 340-051 and 603-074. 3. The permittee with a large concentrated animal feeding operation must also have depth markers in all surface liquid impoundments (e.g., lagoons, ponds, tanks) designed to clearly indicate the: (a) Maximum design volume, (b) Minimum capacity necessary to contain the 25-year, 24-hour rainfall event, including additional freeboard requirements, and (c) Depth of manure and process waste water. Prevention of System Overloading 1. The permittee may not increase the number of animals over 10% or 25 animals, whichever is greater, of the maximum number assigned by ODA in the Notice of Registration and General Permit Summary until an updated plan is approved in writing by ODA (see S3.B AWMP Submittal, p. 12, and S3.D AWMP Changes, p. 13). 2. Animal numbers must not exceed the capacity of the waste storage facilities. S2.G. Handling of Animal Mortalities The permittee must not dispose of animal mortalities in liquid manure or waste water control facilities. Animal mortalities must be handled in such a way as to prevent discharge of pollutants to surface water or groundwater. S2.H. Proper Operation and Maintenance The permittee must at all times properly operate and maintain all facilities and systems used for process waste water collection, storage and utilization, and correct any deficiencies found as soon as possible. S2.I. Maintaining Compliance if System Fails The permittee must control all applications and discharges upon reduction, loss or failure of the waste storage or utilization facilities until the facilities are restored or an alternative method of storage or utilization is provided. Pozzi Dairy AWMP CAFO NPDES General Permit #01-2009 Expiration Date: May 31, 2014 Page 11 of 24 S2.J. S2.K. S2.L. Setback Requirement The permittee must develop a setback for any mechanical application of manure, litter, or process waste water occurring in the land application area(s) adjacent to any surface waters, open tile intake structures, sinkholes, well heads, or other conduits to surface or ground waters where manure, litter, and other process waste waters are prohibited. The setback distances must be included in the permittee’s AWMP. For large concentrated animal feeding operation, this setback must be 100 feet or as a compliance alternative and if demonstrated to the satisfaction of ODA in the AWMP, the permittee for the large concentrated animal feeding operation may: 1. Establish a 35-foot vegetated buffer where manure, litter, and other process waste waters are prohibited; or 2. Demonstrate that a setback or vegetated buffer is not necessary or may be reduced because implementation of alternative conservation practices or field-specific conditions will provide pollutant reductions equivalent or better than the reductions that would be achieved by the 100 foot setback. Manure, Litter, or Process Waste Water Transfers 1. The permittee retains responsibility of the manure, litter, or process waste water until the transfer or export is completed with the required documentation. 2. The permittee must maintain manure, litter, or process waste water transfer or export records as required by S4.C.2(d), p. 17. 3. Prior to transferring manure, litter, or process waste water to other persons, the permittee with a large concentrated animal feeding operation must provide the recipient of manure, letter, or process waste water with the a manure nutrient analysis conducted within the previous 12 months. Proper Disposal of Other Wastes Chemicals, contaminants, and other wastes may not be disposed of in any treatment or storage system for contaminated storm water from the production area, manure, litter, or process waste water unless the system is designed to treat such chemicals, contaminants, or wastes and the chemical, contaminants, or other wastes are identified in the AWMP. In addition, chemicals, contaminants, and other wastes may not be disposed of in any system designed for diversion of uncontaminated storm water.

Animal Waste Management Plan (AWMP) Implementation and Compliance 1. Upon registration to this permit, the permittee must implement its current ODA-approved AWMP developed for its CAFO. 2. The permittee’s ODA approved AWMP is incorporated into this permit by reference. The permittee must comply with all terms and conditions of its ODA-approved AWMP. Failure to comply with the ODAapproved AWMP constitutes a violation of the terms and conditions of this permit. 3. Absence of a AWMP or absence of ODA approval of an AWMP does not allow the permittee to violate the provisions of S2 Discharge Limitations and Operating Requirements, p. 9 or other permit requirements. AWMP Submittal and Public Notice 1. The applicant proposing a new CAFO or electing coverage under this permit must submit its AWMP with the ODA ATR to ODA for review and approval according to the schedule provided in S1.C, p. 6. 2. If necessary to meet the AWMP requirements in this permit, the existing permittee with coverage under the previous version of this general permit must submit a revised or updated AWMP prior to renewing registration under this permit. 3. AWMPs are subject to public notice and participation requirements detailed in condition S1.H, p. 7. AWMP Elements 1. The permittee must ensure that its AWMP is adequate for the proposed or existing population of animals, reflective or the proposed or existing facility operation, and be prepared in accordance with the terms and conditions of this permit, OAR 340-051, and NRCS conservation practice standard guidance 590 for Oregon dated May 2008 entitled Nutrient Management. Note: In the event of any inconsistency between the conditions of this permit and NRCS 590, the conditions of this permit apply. 2. The AWMP may include a schedule for improvement projects. 3. The AWMP must to the extent applicable include the following: (a) Procedures to ensure adequate collection, handling, and storage of contaminated strom water runoff from the production area, manure, litter and process waste water in compliance with the requirements of S2. Discharge Limitation and Operating Requirements. Calculations used to determine that storage capacity exists must be provided, including a demonstration the facilities are at least designed and constructed to contain all manure, litter, process waste water, contaminated storm water runoff from the production area, and direct precipitation from a 25-year, 24-hour rainfall event. (b) Procedures to ensure proper operation and maintenance of the storage facilities; (c) Procedures to ensure proper management of animal mortalities. Animal mortalities may not be disposed of in any storage or treatment system that is not specifically designed to treat animal mortalities; (d) Procedures to ensure that clean water is diverted, as appropriate, from the production area; (e) Procedures to prevent direct contact of confined animals with surface waters; (f) Identification of appropriate site-specific conservation practices to be implemented, including buffers, setback areas, or equivalent practices, to control runoff of pollutants to surface water and groundwater; (g) Protocols to land apply manure, litter or process waste water in accordance with site specific nutrient management practices that ensure appropriate agricultural utilization of the nutrients in the manure, litter or process waste water. The protocols must include the following: (i) The NRCS Phosphorous Index, USDA/NRCS Oregon Agronomy Technical Note #26, revised June 2008, must be completed for all fields that receive manure , litter or process waste water to determine if nitrogen or phosphorous is the most limiting nutrient. The maximum nutrient Pozzi Dairy AWMP CAFO NPDES General Permit #01-2009 Expiration Date: May 31, 2014 Page 13 of 24 application rate must be calculated for the most limiting nutrient (from Technical Note #26) and must account for all other nitrogen and phosphorus sources. (ii) Expected crop yields. (iii) Calculations showing the total nitrogen and phosphorus to be applied annually to each field, including sources other than manure, litter, or process waste water. (iv) Annual manure application rates and an explanation of the basis for determining these rates. For large concentrated animal feeding operations, these rates must be based on actual test data. For other operations, data or “book values” from established reference sources (e.g., Oregon Animal Waste Management program) may be used instead of actual testing. (v) Method(s) used to apply manure, litter, or process waste water. (h) For large concentrated animal feeding operations, protocols for appropriate testing of manure, litter, process waste water, and soil. For other operations, references used instead of actual testing data or test protocols if testing. (i) If applicable, an Agricultural Compost Management Plan as required by OAR 340-096. (j) Frozen soil application procedures if applications of manure, litter, or process waste water will be made to frozen soil. At a minimum, the following must be provided: (i) Description of the potential receiving field(s), estimates of waste amounts and types, and estimated timing of applications. (ii) Aerial photo(s) identifying all areas and surface water bodies within 1,000 ft. of the boundaries of the receiving field(s). (iii) Soil map(s) identifying soil types for receiving field(s). (iv) Topographic map(s) for receiving field(s). (v) Description of the structural practices in place to ensure that no discharges to surface water occur during application and after the soil thaws. (vi) Description of the method used to determine when soil is frozen and management practices to be followed when planning an application and during and after an application to frozen soil. (vii) Description of monitoring and reporting requirements to ensure that the permittee is in compliance with frozen soil application procedures. (k) Procedures for transfer or export of manure, litter, or process waste water. (l) Identification of specific records that will be maintained to document the implementation and management of the minimum elements described above. S3.D. AWMP Changes 1. Requirements for small or medium confined animal feeding operations (see Table 3,p. 15, for an overview) (a) Substantial changes. The permittee must submit any proposal to make substantial changes to its AWMP to ODA for approval at least 45 days in advance of the proposed changes. ODA will public notice the proposal as described in S1.H, p. 7. ODA will notify the permittee of its final decision concerning the proposed changes after the public notice period ends. The permittee may not implement a proposed change until ODA has approved it. The following types of changes to an AWMP are considered substantial: (i) A change in the type of manure system including but not limited to switching from a dry to a liquid manure system, switching from a liquid to a dry manure system, or changing the manure system to accommodate an animal species or type of operation not included in the scope of the current AWMP. (ii) An increase in maximum allowed animal numbers such that the operation becomes defined as a large concentrated animal feeding operation. (b) Non-substantial changes. Public notice of non-substantial changes (described below) to an AWMP is not required; however, the permittee must submit its proposal to make such a change to ODA for approval at least 45 days in advance of the proposed change unless a different timeframe is allowed by ODA. ODA will notify the permittee of its final decision concerning the proposed change after reviewing the proposal. The permittee may not implement a proposed change until ODA has approved it. The following changes to an AWMP are considered non-substantial provided they do not result in a substantial modification listed in paragraph (a) above: Pozzi Dairy AWMP CAFO NPDES General Permit #01-2009 Expiration Date: May 31, 2014 Page 14 of 24 (i) An increase in animal numbers greater than 10% of the registrant’s maximum allowed animal numbers provided the increase does not change the operation into a large concentrated animal feeding operation.

(a) Bypass is prohibited, and the director may take enforcement action against a permittee for bypass, unless: (i) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; (ii) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (iii) The permittee submitted notices as required under paragraph G16.3 of this section. (b) The director may approve an anticipated bypass, after considering its adverse effects, if the director determines that it will meet the three conditions listed above in G16.4(a) of this section. G17. Upset [40 CFR §122.41(n)] 1. Definition. Upset means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. 2. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of paragraph G17.3 of this section are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. 3. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (a) The upset occurred and that the permittee can identify the cause(s) of the upset; (b) The permitted facility was at the time being properly operated; and (c) The permittee submitted notice of the upset as required in paragraph G2.6(b)(ii) of this section (24 hour notice). (d) The permittee complied with any remedial measures required under paragraph G8 of this section. 4. Burden of proof. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof.
