Ye Reverse f.r Inst�tions USE BY SPECIAL REVIEW QUESTIONAIRE The following questions are to be answered and submitted as part of the USR application. If a question does not pertain to your use, please respond with "not applicable", with an explanation as to why the question is not applicable. 1. Explain, in detail, the proposed use of the property. The existing and proposed use of this property is a dairy. The dairy includes an existing dairy milking facility and a proposed new milking facility. Additional related structures include free stall barns for housing milking cows, dry lot pens for dry cows, heifers and immature livestock, a commodity shed and feed area, environmental controls and stormwater and wastewater containment structures and employee housing. This application is for a total of10,000 cattle and supporting structures and facilities. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22. The use is consistent with the Weld County Comprehensive plan through the preservation, enhancement and growth of agriculture. A dairy has existed at the site since approximately the 1960's. This facility is located on prime farmland when irrigated. The facility supports commercial and industrial uses directly related to or dependent upon agriculture. Efforts to preserve productive agriculture land include the maintenance, enhancement and growth of a viable, profitable, agricultural business. The proposed site is not located within a geologic hazard zone or airport overlay zone. The property use is necessary in Weld County to preserve the agricultural economic base historically attributed to the area. The proposed use provides approximately 50 agriculture jobs for Weld County residents. Typically, feedlot and dairy operations contribute 2.5 times their gross sales into the local economy. 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 and the zone district in which it is located. This proposal meets the intent of the agricultural zone district where the site is located. A livestock confinement operation exceeding four(4) animal units is permitted in the A (Agricultural)zone district as a Use-by-Special Review. Public health safety and welfare are protected through adherence to applicable county, state and federal regulations and requirements. 4. What types of uses surround the site? Explain how the proposed use is consistent and compatible with surrounding land uses. Agricultural uses surround this site. There are two feedlots and two dairies within 1 to 1.5 miles of the proposed use. Other uses consist of irrigated and dry land farming, cattle grazing, and hay production. Rural residential homes in the Agricultural zone also exist in the area. This proposal is compatible with the surrounding agricultural uses and the Weld County Comprehensive Plan. 5. Describe, in detail, the following: a. How many people will use this site? Approximately fifty(50) employees, the owners and owners' family, sales representatives and supply delivery people. b. How many employees are proposed to be employed at this site? Approximately fifty(50)employees will work on site through three shifts. c. What are the hours of operation? The facility will continue to operate feeding and milking operations 24 hours per day as it does presently. Equipment operations, trucks, farming activities and maintenance activities other than emergencies will occur primarily during daylight hours. d. What type and how many structures will be erected(built) on this site? Nine freestall animal housing units are planned in addition to a new modern milking facility. Several stormwater containment and wastewater processing ponds will be located south of the freestall barns and milking facility. See "Highland Dairy Site Layout" figure for details and locations. e. What type and how many animals, if any, will be on this site? Approximate numbers are in the table below: Animal Type Weight/Lbs. Number of Head* Milking Cows 1400 5500 Dry Cows 1200 600 Springers 1000 600 Heifers 750 1275 Heifers 450 1275 Calves 200 750 Total 10000 *Individual cattle types and weights will fluctuate. Total not to exceed 10,000 head. f. What kind(type, size, weight) of vehicles will access this site and how often? Typical vehicles accessing this site include feed and hay delivery trucks and semi- tractors and trailers, employee and owner vehicles, animal product vendors, and ag- related equipment. Operating equipment includes typical farming equipment, tractors, loaders and attachments. Semi-Tractor Livestock Trucks 15-20/wk Semi-Tractor Commodity Truck 10/wk Commodity Farm Trucks 5/wk Hay Trucks, Semi-Tractors daily during hay season Silage—daily during silage cutting season Rendering Truck— when needed. g. Who will provide fire protection to the site? Nunn Fire District h. What is the water source on the property? (Both domestic and irrigation) A public water tap issued by North Weld County Water District services the facility. There are five (5) registered irrigation wells and two (2) registered domestic/livestock wells. i. What is the sewage disposal system on the property? (Existing and proposed). Existing septic system(s). Statements of existing septic systems are included in the application documents. New septic systems will service the proposed milking facility bathrooms and employee housing units. j. If storage or warehousing is proposed, what type of items will be stored? Storage and warehousing are not proposed as the primary use of this site. Feedstuffs, livestock bedding, manure, equipment parts and supplies typical of farming activities are stored on site. 6. Explain the proposed landscaping for the site. The landscaping shall be separately submitted as a landscape plan map as part of the application submittal. The facility layout is designed for a grass pasture buffer area on the southwest corner of the parcel. Irrigated farm ground is preserved on the south and eastern parts of the parcel. A windbreak/screen of trees and shrubs is existing on the western boundary of the parcel as shown on the site plan. No additional landscaping is currently planned except as outlined in the Nuisance Management Plan. 7. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Reclamation procedures include compliance with applicable regulations such as the Colorado Confined Animal Feeding Control Regulations to manage solid manure and stormwater runoff until all relative material is adequately removed. Should the facility be permanently discontinued for use as a dairy, it will be marketed under applicable county planning and zoning regulations to its greatest and best use. 8. Explain how the storm water drainage will be handled on the site. Storm water drainage is handled by a series of stormwater and aerated wastewater containment and treatment ponds which will be maintained and operated in accordance with the Colorado Confined Animal Feeding Control Regulations. Wastewater recycling through the facility is planned. Remaining water from these ponds is used to irrigate farm ground. Specific details regarding storm water and wastewater management are outlined in the Comprehensive Manure and Wastewater Management Plan. 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. New construction will begin immediately. The application material is a long-range plan for the ultimate capacity of the facility. Final construction may be 10 or 15 years from inception. 10. Explain where storage and/or stockpile of wastes will occur on this site. Most of the manure produced at the facility is land applied to farmground after being removed from pen surfaces. Remaining solid manure will be stockpiled and composted on the eastern portion of the parcel. Storm water and process wastewater will be stored in wastewater retention structures designed to meet State CAFO regulations. No hazardous material storage is proposed for this site. Stormwater and wastewater will be periodically land applied at agronomic rates. Details of the manure management system are outlined in the Comprehensive Nutrient Management Plan. Debris and refuse are collected and removed by BFI trash service.

Highland Dairy Comprehensive Manure& Wastewater Management Plan 3 AgPro Environmental Services, LLc 05.31.2002 Site Description Facility Highland Dairy is an existing dairy facility located in the northeast corner of the intersection of Weld County Roads 39 and 92, approximately 3.5 miles east, northeast of Pierce, Colorado. Dairy construction is industry-typical steel and wood posts, pipe and cable fence, concrete feed aprons and feed bunks, feed alleys and cow movement alleys, feed storage areas and associated storage structures and maintenance facilities,waste management and control structures. Highland Dairy is planning an expansion of the facility. The ultimate maximum capacity at Highland Dairy will be 10,000 head including up to approximately 5,500 milking, 1,200 dry cows and springer heifers, with the balance made up of young heifers and calves. Cattle numbers fluctuate throughout the year as calves are born, and cattle are bought and sold. However, the average number of cattle at the facility is expected to be approximately 10,000 head. Farm ground surrounds the facility. Maps The maps described below are included in Appendix A. Topographic Map The Topographical Location Map shows the location of Highland Dairy, land application areas, topography and major drainages. Site Layout Map The Site Layout Map details the expanded configuration of the dairy. Soils Map The USDA Soil Survey map details the area's soil types. Also included are detailed soil descriptions. Stormwater and Process Wastewater Management Surface Runoff Highland Dairy controls stormwater with several retention ponds at appropriate locations throughout the site (see Site Layout Map in Appendix A). • Northwest area serviced by NW Storm Pond • Southeast area serviced by SE Storm Pond • Compost area serviced by Compost Storm Pond • Small amount of Northeast area serviced by Process Pond System (non-dairy areas, including freestall roofs, are diverted away to the east and eventually off site) Highland Dairy will monitor the site and maintain appropriate diversion structures to ensure runoff enters the various stormwater collection systems. 25 year, 24-hour Storm The 25-year, 24-hour storm event for the area east, northeast of Pierce, Colorado is 3.2 inches. Using the SCS runoff curve number 90 for un-surfaced areas and 97 for paved or covered areas, Table 1 was generated: Highland Dairy Comprehensive Manure& Wastewater Management Plan 4 AgPro Environmental Services, LLu 05.31.2002 Table 1 -25-Year,24-Hour Storm Containment Requirements NW Area SE Area Compost NE Area Area Surface Runoff from Storm,Acre-Feet 6.57 1.90 3.16 0.17 Rain falling directly on ponds, Acre-Feet 0.61 0.24 0.34 2.32 Total Containment Capacity Required, Acre-Feet 7.18 2.14 3.51 2.49 Containment Capacity Available,Acre-Feet 7.70 2.63 3.75 65.38 Excess Containment Capacity Available, Acre-Feet 0.52 0.49 0.24 62.89 The 25-year, 24-hour storm and pond capacity calculations are located in Appendix B. 10 year, 10-day Storm The 10-year, 10-day storm event for Nunn, Colorado is 3.36 inches.

Surface Runoff Management Highland Dairy will divert runoff from the freestall-barn roofs, new milk parlor's roof, and areas between freestall barns away from the stormwater retention system. Runoff from the furthest southwest freestall's south roof will enter the NW Storm Pond and runoff from the existing freestall's south roof will enter the Process Pond System. Stormwater from the northwest, southeast and compost areas will drain to each appropriate pond and enter via sheet flow. One corral in the southwest corner of the dairy will be self-contained utilizing a containment berm. As the SW corral fills with stormwater, it will eventually force runoff toward the NW Storm Pond. Stormwater left within the corral can either be pumped out into a storm pond or left to evaporate. Highland Dairy will maintain the lagoon systems to contain a 25-year, 24-hour storm event. Should stormwater runoff or process wastewater elevate the lagoons beyond their capacity to contain a 25-year, 24-hour storm, the system will be dewatered within 15 days to achieve the required retention capacity as outlined in the state's regulations. Pumping to surrounding farm Highland Dairy -- Comprehensive Manure& Wastewater Management Plan 5 AgPro Environmental Services, LLC 05.31.2002 ground dewaters the lagoons. Highland Dairy has available approximately 73 acres of flood- irrigated farm ground and 147 acres of center-pivot irrigated land available for application of wastewater. The land application areas are located adjacent to the dairy west and southeast respectively (see the Topographic Map in Appendix A). Process Wastewater Highland Dairy generates process wastewater within the milking parlor. It is estimated that Highland Dairy will generate a maximum of 25,000 gallons of process wastewater per day at maximum capacity. A table summarizes the process wastewater in Appendix B. Dairy parlor floors and walls, milking equipment, pipelines, and tanks are washed with fresh water. Wastewater flows via concrete alley between the freestall barns to the south into a mechanical separation system and then into an earthen settling basin. Water then flows into a primary pond, and into subsequent secondary ponds before it is available for land application. The freestall barns are flushed utilizing recycled water from the last secondary pond, thus adding no additional water to the system. Pumping to surrounding farm ground dewaters the lagoons. Highland Dairy has available approximately 73 acres of flood-irrigated farm ground and 147 acres of center-pivot irrigated land available for application of wastewater. The land application areas are located adjacent to the dairy west and southeast respectively (see the Topographic Map in Appendix A). Ground Water Protection The stormwater ponds and the process wastewater system will be constructed to meet the 1/32 inch-per-day maximum seepage requirement in the state's regulations. Upon completion of the wastewater retention structures, the liners will be inspected and certified by a licensed professional engineer. Proof of lining will be kept on site and copies forwarded to the Weld County Department of Public Health and Environment. Pond Levels The stormwater ponds and process wastewater ponds will have appropriate pond-level gauges installed when built. The gauges will show incremental depths as well as the appropriate level to maintain capacity for a 25-year, 24-hour storm event. Floodplains AgPro Environmental Services, LLC, has reviewed the Weld County FEMA maps and contacted the Colorado Water Conservation Board concerning possible floodplains in the area of Highland Dairy. No maps exist for the area of Highland Dairy, leading us to conclude that Highland Dairy is not located within a mapped 100-year floodplain. Off-Site Drainage Diversion While Highland Dairy is not within a mapped 100-year floodplain, there is an area drainage waterway that goes through the dairy property. Highland Dairy proposes to divert this drainage around the facility on the north and east. The proposed diversion will be capable of delivering the flow from a 100-year storm. Detailed design calculations are located in Appendix C. The diversion is shown on the Site Layout Map in Appendix A. Highland Dairy - Comprehensive Manure& Wastewater Management Plan 6 AgPro Environmental Services, LLC 05.31.2002 Land Application of Stormwater/Process Wastewater Wastewater will be pumped from the ponds onto farm ground in accordance with the Colorado CAFO regulations, "tier two" land application requirements. Highland Dairy will have, on site, adequate pumping equipment to dewater the ponds. They can utilize a PTO-driven pump, a floatable pumping system, or an installed permanent pumping system. The primary application areas for stormwater/process wastewater are flood-irrigated land west of the dairy consisting of approximately 73 acres and 147 acres of center-pivot irrigated land southeast of the dairy. Table 3 below shows the land necessary to utilize nutrients from a 25-year, 24-hour storm. The nitrogen content and losses are based on Colorado State Cooperative Extension Bulletin No. 568A, Best Management Practices for Manure Utilization. The calculation in Table 3 indicates that Highland Dairy requires approximately 120 acres of corn to utilize the nitrogen contained in runoff generated from a 25-year, 24-hour storm.

Highland Dairy does not apply wastewater on frozen ground or during rainfall events. • Highland Dairy --- Comprehensive Manure& Wastewater Management Plan 7 AgPro Environmental Services, LLC 05.31.2002 Average Years' Stormwater / Process Wastewater Application Four, five-year wastewater generation tables can be found in Appendix B. The tables estimate the average annual amount of wastewater to be land applied from each separate area. The tables estimate land application amounts by maintaining enough capacity to contain a 25-year, 24-hour storm. The tables included in Appendix B are: • Table 1: Stormwater/Process Wastewater Accumulation Calculation (Average Years) (NW Dairy Area) • Table 2: Stormwater/Process Wastewater Accumulation Calculation (Average Years) (SE Dairy Area) • Table 3: Stormwater Accumulation Calculation (Average Years) (Compost Area) • Table 4: Stormwater/Process Wastewater Accumulation Calculation (Average Years) (NE Dairy Area) The tables account for the following: • Average monthly precipitation values from local weather data • Average monthly lake-evaporation data from local weather data • Process wastewater generation rate of 25,000 GPD for the northeast area only • Evaporation area equal to the bottom of the ponds for the three stormwater ponds • Evaporation area equal to the surface area of the settling and primary ponds full and the secondary ponds 3/2 full for the process wastewater system • Northwest drainage area of 35.6 acres • Southeast drainage area of 10.4 acres • Compost drainage area of 17.5 acres • Northeast drainage area of 0.71 acres • Runoffpercentage from NRCS National Engineering Handbook • Trial-and-error pumping amounts to maintain capacity for a 25-year, 24-hour storm The calculation table shows that annual land application of approximately 12.4 acre-feet of process wastewater will maintain capacity for a 25-year, 24-hour storm. Table 5 below shows the land necessary to utilize the nutrients from average years' pumping requirements in accordance with tier two of the state CAFO regulations. The nitrogen content and losses are based on Colorado State Cooperative Extension Bulletin No. 568A, Best Management Practices for Manure Utilization. The calculation in Table 5 indicates that Highland Dairy requires approximately 96 acres of corn to utilize the nitrogen contained in average years' stormwater/process wastewater.

The calculations utilize an equilibrium mineralization rate for organic nitrogen of 42 percent. This represents the cumulative organic nitrogen released over three years. The previous three tables indicate that Highland Dairy has enough available land (220 acres) to assimilate nutrients produced in stormwater/process wastewater year after year. Also, the nitrogen loss calculations are for flood-irrigated fields. While Highland Dairy does have some flood-irrigated acreage, it also has center-pivot irrigated land, which would have more nitrogen loss during application. Therefore, the calculated land required is conservative, and if Highland Dairy utilized the center-pivot irrigated acreage, the land required for nutrient utilization would be less. Solid Manure Management Highland Dairy manages solid manure through routine pen cleaning and maintenance. Pen density is managed to optimize the surface area and keep cows clean while maintaining solid, dry footing for livestock. Highland Dairy cleans outside pens at least annually and flushes the freestall barns daily. Manure from the outside corrals and solids off of the mechanical separation unit are composted together on site. Compost is sold or given away to area farmers for utilization on their land. The composting area is noted on the site layout map in Appendix A. Table 6 below calculates the amount of manure produced and the associated nutrients on an "as excreted basis". In addition, `as-hauled' and `composted' weights are calculated accounting for predictable moisture losses. The calculations are based on NRCS Agricultural Waste Management Field Handbook, for various size dairy cattle and an average capacity of 5,500 lactating cows.

They plan to give solid manure and/or compost away to area farmers for use on the farmers' land. Nutrient Utilization Nitrogen is the element that most often limits plant growth. Nitrogen is naturally abundant. However, it is the nutrient most frequently limiting crop production because the plant available Highland Dairy -- Comprehensive Manure& Wastewater Management Plan 9 AgPro Environmental Services, LL, 05.31.2002 forms of nitrogen in the soil are constantly undergoing transformation. Crops remove more nitrogen than any other nutrient from the soil. The limitation is not related to the total amount of nitrogen available but the form the crop can use. Most nitrogen in plants is in the organic form and is incorporated into amino acids. By weight, nitrogen makes up from 1 to 4 percent of harvested plant material. Essentially all of the nitrogen absorbed from the soil by plant roots is in the inorganic form of either nitrate or ammonium. Generally, young plants absorb more ammonium than nitrate; as the plant ages the reverse is true. Under favorable conditions for plant growth, soil microorganisms generally convert ammonium to nitrate, so nitrates generally are more abundant when growing conditions are most favorable. Manure and process wastewater is most typically applied for fertilizers and soil amendments to produce crops. Generally, manure and process wastewater is applied to crops that are most responsive to nitrogen inputs. The primary objective of applying agricultural by-products to land is to recycle part of the plant nutrients contained in the by-product material into harvestable plant forage or dry matter. Another major objective in returning wastes to the land is enhancing the receiving soil's organic matter content. As soils are cultivated, the organic matter in the soil decreases. Throughout several years of continuous cultivation in which crop residue returns are low, organic matter content in most soil decreases dramatically. This greatly decreases the soil's ability to hold essential plant nutrients. Land application of Highland Dairy's stormwater/process wastewater and solid manure to recycle valuable nutrients is a practical, commonly accepted best management practice given that fertilization rates are applicable and that deep soil leaching does not occur. Reference material from Colorado State University is included in Appendix D of this CMWMP for use by the operator in making sound decisions pertaining to the land application of process wastewater and/or solid manure. Soil Testing The purpose of soil sampling is to ensure that the quantity of nutrients later applied to the soil will not lead to undesirable nutrient levels in the soil. Knowledge of nitrogen and other nutrients present in the soil, combined with specific crops and realistic yield goals, are key for calculating appropriate manure and/or stormwater application rates. Highland Dairy will test soil on land application areas annually using protocol in Appendix E. Irrigation Water Testing Highland Dairy will test irrigation water once per year using the protocol in Appendix E. Manure and Stormwater Testing Manure and stormwater testing are essential components of a complete nutrient balance. The amount of nutrients in solid and liquid waste determines the amount that can be land applied agronomically. Highland Dairy will test stormwater/process wastewater and solid manure at least once per year following the protocol in Appendix E. Highland Dairy Comprehensive Manure& Wastewater Management Plan 10 AgPro Environmental Services, LLC 05.31.2002 Agronomic Calculations Agronomic rate is the rate at which plants will utilize nutrients while limiting the amount of nutrients that are lost via percolation through the soil or runoff. Highland Dairy will perform agronomic calculations for every field upon which wastewater or solid manure is applied. Agronomic calculations take into account: • The crop to be grown • Nitrogen content in irrigation water • A realistic yield goal • Nitrogen credit from previous legume crop; • Total nitrogen required to meet the yield and goal • Plant available nitrogen (PAN) in the • Residual soil nitrate wastewater and solid manure • Soil organic matter Forms for performing agronomic calculation are in Appendix F. One agronomic calculation sheet is used for each field on which wastewater or solid manure is applied. In addition, reference materials from Colorado State Cooperative Extension is located in Appendix D, which includes nitrogen requirement information for corn, wheat and other crops commonly grown in Colorado.

Livestock manure contains significant quantities of N, P, and K, and smatter amounts of nutrients such as Ca, Mg, Mn, Zn, Cu, and S.

Smaller feeding operations that directly site-specific values. discharge into state waters or are located in hydrologically sensitive areas may also fall under this regulation. Animal feeding operations are directed to employ Best Management Practices (BMPs) to protect state waters. Nutrient Management Planning Sound management practices are essential to maximize the agronomic and economic benefits of manure while reducing the risk of adverse environmental consequences. Livestock producers do not intentionally put water quality at risk. The problems that occur are usually a result of inattention due to the need to focus limited management time on herd health and production. Virtually every regulatory and voluntary manure management approach now calls for producers to develop a Nutrient Management Plan. This plan documents approximately how much manure is produced and how it will be managed. At the core of these plans is the concept that manure will be applied at "agronomic rates" to crop lands. 1 -- . ... The agronomic rate is a nutrient application rate -cable _squiva e • • based upon a field-specific estimate of crop needs and <Et st C, -�^^ - • ini �:. _ an accounting of all N and P available to that crop prior st► �, to manure (and/or fertilizer) application. Implicit Factor N within the agronomic rate concept is an application Slaughter and Feed Cattle, a,8+•""� — rate that does not lead to unacceptable nutrient losses. • • 1 1 The agronomic rate is not something that can be directly obtained from a textbook or tables. Rather, it must be evaluated for each farm and field. Knowledge of manure or effluent nutrient content and residual soil • nutrients is critical to determining how much can be safely applied so that the agronomic rate is not ex- ceeded. While producers were encouraged in the past to fertilize for maximum crop yields, now they must also consider the environmental risk of nutrient losses in determining how much manure to apply. By knowing the relationship between manure nutrient content, residual soil nutrients, and crop needs, wise decisions can be made such as where to spread manure, how much to spread, and on which nutrient to base the application rate. Long-range planning is fundamental to optimizing manure benefits while minimizing environmental concerns. The basic elements of a nutrient manage- ment plan are: 1. Estimates of manure and waste water production on the farm 2. Farm maps which identify manure stockpiles and lagoons, potential applica- tion sites and sensitive resource areas 3. Cropping information and rotation sequence 4. Soil, plant, water, and manure analyses 5. Realistic crop yield expectations 6. Determination of crop nutrient needs 7. Determination of available nutrient credits 8. Recommended manure rates, timing, and application methods 9. Plans for operation and maintenance of manure storage and utilization. Documentation of any manure to be sold, given away, or used for purposes other than as a soil amendment. If animal feed rations are modified to reduce nutrient content or volume of the waste as part of the management strategy, this also should be documented as part of the waste management plan. Advances have been made in recent years in feed formulation for reducing N and P excretion without reducing rate of gain. The "ideal protein concept" is a feeding method for monogastrics in which crude protein levels are reduced and amino acids are supplemented in order to reduce N excretion. For reduction of phosphorus excretion, adding phytase to the diet has been shown to increase P availability to hogs and chickens. Most of the research on nutritional approaches to reducing manure nutrient excretion has been done on monogastrics, but research is in progress on cattle feeding methods for this purpose. 2 • Nutrient management plans are no Longer just a good idea: they are essential for documenting proper stewardship and regulatory compliance. This publication is designed to help producers develop their own nutrient manage- ment plans in a relatively simple format. However, technical assistance is also available to producers from their local Certified Crop Adviser (CCA), Cooperative Extension agent or USDA NRCS conservationist. Manure Handling and Storage Livestock feedlots, manure stockpiles, runoff storage ponds, and treatment lagoons represent potential point sources of ground water contamination. Research has shown that active feedlots develop a compacted manure/soil layer, which acts as a seal to prevent leaching. When cleaning pens, it is very impor- tant to avoid disturbing this seal. Workers need to be trained to correctly use manure loading machinery to maintain a manure pack on the surface. In addition to maintaining the integrity of the "hard pan" under feedlot pens, it is critical to create and maintain a smooth pen surface that facilitates proper drainage and runoff collection. Pens should be designed with a 3 percent to 5 percent slope for optimum drainage. Low spots and rough surfaces should be filled and smoothed during pen cleaning. Abandoned feedlots have a large potential to cause NO3 leaching as the surface seal cracks and deteriorates. For this reason, pens need to be thoroughly cleaned and scraped down to bare earth prior to abandonment. Revegetation of —the old pens is also important to help absorb excess soil nutrients and prevent erosion. Manure stockpiles should be located a safe distance away (at least 150 ft.) from any water supply and above the 100-year flood plain unless flood proofing measures are provided. Grass filter strips or sediment basins can be used to reduce solids and nutrients in runoff. For land with a slope of greater than 1 percent, plant a strip of a dense, sod-forming grass such as smooth brome or pubescent wheatgrass at least 20 to 50 feet wide around the downhill side of any feedlot or manure stockpile to filter potential contaminants in runoff water. More precise fitter strip seeding recommendations may be obtained from the local USDA-NRCS office. Liquid Effluent and Runoff Collection and Storage Storm water and wastewater runoff from feedlots can Liquid waste holding structure contain high concentrations of nutrients, salts, pathogens, and oxygen-demanding organic matter. Preventing storm water from passing across the feedlot surface by installing terraces or diver- sion channels above the feedlot is a BMP that can significantly reduce the volume of wastewater. Decreasing the active lot area can also help reduce the contaminants moved by storm water. The criteria for waste water treatment lagoons and holding ponds is stricter than for runoff containment ponds. Runoff _ 4 —containment ponds are necessary for large feeding operations to sv a l'--. mold excess wastewater until it can be land applied or evaporated. These should be constructed on fine-textured soils (such as silty clays, clay foams, or clay) with a Lining of soil compacted to a 3 minimum thickness of 12 inches with an additional 18-30 inches of soil cover above the compacted soil. On coarse textured or sandy soils it may be necessary to import bentonite clay or use synthetic liners or concrete. Seepage is required to be less than 0.25 inch/day if the pond contains runoff only. However, if the pond stores process wastewater, the seepage requirement is 0.03 inch/day. New holding facilities must be designed to contain the runoff from a 25-year, 24- hour storm event and should be located above the 100-year flood plain and at least 150 feet down gradient from any well. Do not site storage ponds or treatment lagoons in areas with a high water table (within 10 ft. of the bottom of the pond). The local USDA-NRCS office can provide help with pond or lagoon design. Manure Treatment There are numerous options for treating or processing manure such as composting, solid separation, aeration, anaerobic digestion, and constructed wetlands. A growing number of producers have become interested in manure treatment systems as a way to reduce volume and odor and enhance the value and acceptance of manure. Careful evaluation of the economic feasibility of a manure treatment system and discussion with a professional engineer is recommended before implementing a new treatment system. II \ Composting is a biological process in which microorganisms . " `. convert organic materials, such as manure, into a soil-like mate- rial. During composting, some N is lost from the manure as NH3 —may " gas. Most of the remaining N is tied up within stable organic compounds which will become slowly available to plants after soil application. Composted manure has less odor and is easier to haul - and store than raw manure because the volume and weight can be � r reduced by as much as 50 percent. '=' s Solid separation is a viable treatment for wastewater from Cleaning pens milking parlors or hog operations. Settling basins or vibrating screens are used to remove solids from the wastewater resulting in reduced odor and less lagoon loading. This treatment requires an investment in equipment and maintenance, but improves the ease of handling the wastewater. Aeration of wastewater storage ponds increases the oxygen level in waste- water and reduces odors. Aeration can be achieved through mechanical means or through gas exchange with the air in large, shallow ponds. The disadvantages of aeration include high energy costs for mechanical aeration and additional maintenance expense. Anaerobic digestion is another treatment option in which manure is digested to produce energy for farm use or possibly for sale to a local power company. This treatment can require a large start-up investment and high maintenance, but significantly reduces manure odors because the treatment vessel is enclosed to capture gases. Maintenance costs can be offset by the use of the energy produced by the combustion of the gases. Constructed wetlands can be a useful manure treatment option because of high nutrient use of wetland plants and the denitrification process which transforms nitrate into gaseous nitrogen forms. The disadvantages include 4 _,construction costs, the need for solid separation prior to wetland treatment, and .he need to manage the wastewater discharged from the wetland. Developing a Nutrient Management Plan [NMP) Worksheets to help develop a nutrient management plan can be found near the end of this publication. They are provided as a staffing place to help producers establish sound manure management. Developing a plan is just the beginning. Implementation of the plan and follow up are required to best manage your operation. NMP Section 1.

Determining laud Needs for Long Term Manure NtilizaNn One of the first steps in developing a long term nutrient management plan is to determine if adequate land is available for utilization of the manure and effluent produced. If the land base is determined to be inadequate, arrange- ments must be made to reduce manure production or find alternatives to over- application. To estimate the minimum land base required, you need to know the annual manure production of your facility and have a manure sample analyzed for total N, P, and K. Then calculate the best estimate of annual nutrient removal on a per acre basis. For this calculation, use conservative estimates of annual crop nutrient removal and assume that all N and P in the manure is crop available unless you are using liquid effluents with known N volatilization rates. Total manure production divided by acceptable application rates (tons or gallons per acre) will give an estimate of the land base needed for safe manure utiliza- tion (Calculation 2). This is not the same calculation as is used for determining the agronomic rate of application for a specific field for a specific year. 1 Total N in manure is used to ' t:f;. ` calculate an estimate of safe long q term solid manure application rate because all of the applied N E - yl that is not Lost to leaching or °` ' = ' volatilization will eventually `$z� •.r L z '. become available to the crop. . Liquid wastes such as swine effluent can have a large loss s component due to ammonia volatilization. Long term planning r't - _ .

Excessive manure applications to cropland have been shown to result in P movement to water and subsequent degradation. Manure management plans should consider P loading when runoff from a field is likely to enter sensitive water bodies. In addition, if the soil test shows that extractable P is in the "high" or "very high" range and P movement is likely, manure should be applied at rates based on crop P removal. For planning purposes, all of the P in the manure should be considered crop available in these cases. The consequence of P based management for a producer is that more land is required to safely utilize the manure. Bite Assessmeet The final aspect of the land and resource inventory is an assessment of the manure storage and utilization sites. Site maps of the farm and feeding opera- tion-are an important part of any nutrient management plan. Obtain aerial maps B 1 from your local NRCS office or develop your own maps if necessary. Identify manure storage facilities, fields receiving manure, and any wells, surface water or shallow ground water. These maps can help you identify sensitive resource areas such as surface water bodies that might receive runoff from your farm. Appropriate BMPs such as buffer areas, set backs, reduced application rates, or application timing limitations may be identified as a part of these maps. To determine the pollution potential at your site, the following questions need to be considered: Manure and wastewater storage site evaluation 1. Is the soil texture coarse (sandy with low amounts of clay)? 2. Is the depth to ground water less than 50 feet in the � vicinity of manure storage? r i 4 ;r ' 3. Have recent well water analyses indicated that local ' ground water NO3-N levels are increasing? 4. Is the horizontal distance of the feedlot to surface water bodies (creeks, ponds, drainage ditches, etc.) or wellheads • less than 150 feet? 5.

To get pda -13D a good, representative soil E ,., _- sample, it is recommended that a _« corKen minimum of 1 soil core per 10 »s x acres or at least 10 cores on fields 40 acres or smaller be collected to form the composite sample for each depth increment. Samples should be thoroughly mixed and either air-dried or delivered to the lab immediately. In situations where effluent or manure is applied in the fall after crop harvest, NH, in the animal waste may not be converted to NO3 prior to spring soil sampling. Additionally, fields with long manure histories may also have a ,ignificant amount of NH4 in the rootzone due to increased mineralization rates. NH, is available to crops and should be credited as part of the N budget in these particular situations. n i Manure is an extremely variable i? t ' material whether in solid or liquid form. '` v+ A representative manure sample is ,t_ critical for a reliable analysis. A mini- mum of six sub-samples should be taken and mixed together for analysis. When sampling a solid manure stock- 47, pile, remove the crust, and use a bucket r,4 -' auger or a sharpshooter (a narrow shovel) to core into the pile as deeply as possible.

' When sampling a liquid manure or `.A • wastewater, there are several ways of sampling.

These lab reports, along with a current manure analysis, should be attached to your nutrient management plan. When plant tissue tests are used to determine in-season fertilizer needs, they should also accompany the plan. See Colorado State University Cooperative Extension Fact Sheet 0.520 for informa- tion on analytical laboratories. Crop Netrleet Need Plant nutrient need depends upon the crop, growing conditions, and actual yield. The crop rotation will determine nutrient needs and nutrient carryover from the previous crop. In some cases, such as a three year stand of alfalfa, nutrient applications are based on more than one year of production. Table 6 12 —indicates approximate N and P content of dry harvested crops. This information can be used to estimate actual crop nutrient removal. Due to inherent ineffi- ciencies in plant uptake, fertilization rates often include an additional amount to compensate for these losses. Tables 7 and 8 contain current Colorado State University fertilization suggestions for selected Colorado crops; information on other crops can be obtained from your local Cooperative Extension office. Realistic Yield Expectations The expected crop yield is the basis for determining how much N and P fertilizer will be needed. Generally, the higher the yield expectation the higher the nutrient requirement. Over-estimating potential crop yield will result in over application of fertilizer or manure. For this reason, producers are encouraged to base yield expectations on a docu- mented 5 year field average plus an additional 5 percent for above average growing conditions. Each field should have a yield history and ry r expectation. , Reterminind Total Nutrient Needs _ Crop nutrient needs are deter- mined using your yield expectations ` and table values for fertilizer rates or a -- crop nutrient removal values. Most > soil laboratories will also give 1 may '- fertilizer recommendations with soil to fi c/' test results. Be sure you understand N/ .r t ki the lab's fertilizer recommendation _ {" u " philosophy to be sure it is compat- N ° 1' " ible with the production and envi- ronmental goals of your operation. In some cases, fertilizer appli- cation rates will need to be adjusted " • a ` Uzi - ' "� above or below the standard table #.g b ` r'r b 'a� k R } -- '1 7 values. Examples of these situations n r p i .1 grfr: ,z;',411:".c. would be 1) where high amounts of crop residue remain, increasing N need by up to 30 lb./acre, 2) where a starter fertilizer is needed due to s, h s tr �+ p ES 2_ .4K' `.*.7.' .,.....

X S' 13 Available N aad P in Mann The total amount of N in manure is not plant available in the =' first year after application due to the slow release of N tied up in '114'1 R. (611: organic forms. Organic N becomes available to plants when soil microorganisms decompose organic compounds such as proteins, and the N released is converted to NH4. This process, known as mineralization, occurs over a period of several years after manure application. The amount mineralized in the first year depends upon manure source, soil temperature, moisture, and handling. In general, anywhere from 15 percent to 55 percent of the organic N in manure becomes available to the crop in the first year after • 7° -- application depending upon climate and management factors. sYr '' Jfr; Nitrogen availability can be estimated as a fraction of the total N 11 -` content of manure or as a fraction of the organic N content. • 'Jr .. :4. Organic N is usually determined by subtracting the NH, and NO3 from the total N content of the manure. This approach is more accurate when reliable NH, content and NH3 volatilization numbers are available. Mineralization of N from applied manure will continue to provide nutrients to the soil system for several years after application. This abl� S " �S <7 rrr M d 1 tIiryi '+ additional N must be accounted for in the nutrient management plan if manure will be applied again to the same field within three years. Mineralization credit for the second and third years after application should be based upon a fraction of this initial organic N content (Table 9). Alter- natively, annual soil sampling for residual soil NO3-N, NHa N and organic matter can be used to estimate mineralization credit in subsequent years. Phosphorus contained in manure is usually considered to be entirely plant available in the first year after application. In reality, some fraction of the P is tied-up -15© in forms that are not immediately available r '� o , wtra- 1/9, to plants. If soil test Pis in the "low to r "' e � S -,r4ter medium" range and the soil is high in time content, it may be appropriate to assume Arai:i� *" • xi that only 80 percent of the P will be plant available in the first year. volatilization lerns new scan .

The rate of volatilization increases Pouf,,, under warm, dry, or windy conditions. Volatilization losses Adapted from USD4,Ag Wa from liquid effluents can result in large N losses, since much of the N in effluents is in the NH, w f1 ;` .J, form, which is easily ' -+ ' 1 ,' converted to ammonia gas.

Additionally, accurate measurement of NH4 content of manure is confounded by a high degree of variability in NH4 concentration in the manure stockpile. The current scientific literature reports losses from sprinkler applied effluents from 10 percent to over 80 percent of the ammonia fraction. For planning purposes, 20 percent to 30 percent of the ammonia can be assumed lost to volatilization during cool season application, white 40 percent to 60 percent may be assumed lost from the soil surface during summer applications. The amount of loss can be reduced by prompt incorpora- tion. In any case, post-season soil testing will provide feedback on how much N is in the soil system after the crop *harvested.

Irrigation water containing NO3 can supply N to the crop since it is applied and taken up while the crop is actively growing. Water tests for NO3-N should be taken periodically during the irrigation season to accurately calculate this credit. Multiply p.m. NO3-N by 2.7 lb./acre foot times the amount of irrigation water consumptively used by the crop prior to the mid-reproductive stage (in acre feet) to determine lbs. N/acre applied in the irrigation water. Inexpensive quick tests are available for on-farm water testing. If a water sample is taken for laboratory analysis, it should be kept refrigerated, but not frozen, until it gets to the lab. Legume crops can be a very significant source of plant available N due to bacterial N2 fixation in root nodules. Plowing down a good stand of alfalfa may release more than 100 lbs. of N per acre in the first year after plowdown. The amount of N credit given for legumes depends upon the crop, stand, and degree of nodulation. A minimum of 30 lbs. of N/acre should be credited in the first year after any legume crop (Table 11). Total all available nutrient sources from soil testing, irrigation water, legumes and any other organic amendments to determine the total nutrient credit. Due to the difficulty of accurately assessing these credits, be sure to scout fields for nutrient sufficiency during the vegetative growth stages.

If soil N, P or E.C. increases significantly over time, manure use should be discontinued until nutrients in the rootzone decline below crop response thresholds. NMP Section 3. Nutrient Use Summary Opentiue iii Maieteeiuee Farm-wide accounting of manure and fertilizer application is the final aspect of a nutrient management plan. This is important to help document a balance between manure production and utilization. Worksheet 3 is provided to help record annual application data. After tallying total nutrient application, you can evaluate nutrient sufficiency or excess on the farm by comparing these numbers to manure production on Worksheet 1. A number of other items should be assessed on an annual basis as a part ^ of nutrient management planning. These include equipment calibration, soil tests, and monitoring water quality near the operation. Accurate record keeping is an essential component of any manure manage- ment program. Keeping accurate recbfds allows managers to make good 11 C decisions regarding manure and nutrient applications. Additionally, these records provide documentation that you are complying with state and local regulations to protect Colorado's water resources. All operators should maintain records of nutrient management plans for at least three years. Spreader Calihratin The value of carefully calculating manure application rates is seriously diminished if manure spreaders are poorly calibrated. Proper calibration is essential in order to apply manure correctly. Manure spreaders discharge at widely varying rates, depending on travel speed, PTO speed, gear box settings, discharge openings, and manure moisture and consistency. Calibration requires measurement of manure applied on a given area. To check spreader calibration, you must know the field size. Secondly, count the number of loads of manure applied to the field. Weigh at least three of the toads, and calculate the average weight. Finally, multiply the number of loads by the average weight, and then divide by the field acreage. This provides you the average application rate per acre for the field. Adjust the spreader or ground speed as necessary to achieve the desired rate. Remember to recheck the calibration whenever a different manure source with a new moisture content or density is applied. Using good equipment and the proper overlap distance will ensure better nutrient distribution and help avoid "hot spots" or areas with nutrient deficiency. (See Colorado State University Cooperative Extension fact sheet 0.561 for more information on spreader calibration.) Fellow Up and Moatterieu Determining agronomic rates of manure or effluent application is not an exact science. Climactic, soil, and management factors influence crop nutrient uptake, mineralization rate, volatilization and overall nutrient availability. Producers must continue to monitor crop yields, as well as soils within and below the rootzone, to determine what adjustments are needed each year in the operating plan to continue protecting water quality. 21 - lest Management Practices for Manure Utilization Guidance Principle: Collect, store, and apply animal manures properly to optimize efficiency while protecting water quality. To select manure BMPs that achieve water quality goals and the greatest net returns for your operation, consider: • most suitable practices for your site and management constraints • need to protect sensitive resources and areas General BMPs 3.1 Develop a nutrient management plan for your operation that includes: 1. Estimates of manure production on your farm 2. Farm maps which identify manure stockpiles, potential application sites and sensitive resource areas 3. Cropping information 4. Soil, plant, water, and manure analysis 5. Realistic crop yield expectations 6. Determination of crop nutrient needs 7. Determination of available nutrient credits 8. Recommended manure rates, timing, and application methods 9. Operation and maintenance plans 3.2 Base manure application rates on crop phosphorus (P) needs IF soil test P is in the high or very high category, the field drains to any sensitive surface water body, AND P movement is likely. In most other cases, appli- cation rates may be based on crop N needs. 3.3 Apply commercial N and P fertilizer to manured fields only when soil available N and P from manure application does not satisfy crop needs. 3.4 Cease effluent application if crop is destroyed during growing season. Plant winter cover crops to scavenge excess nutrients when crop uptake is tower than expected due to hail or other yield limitations. 3.5 Maintain nutrient management plans and actual manure and fertilizer management records on file a minimum of three years or the duration of your crop rotation, if longer than three years. 3.6 Scout fields for nutrient deficiencies/sufficiency throughout the season in order to identify and correct problems that may limit economic crop yields. 21 Manure Application BMPs 3.7 Incorporate manure as soon as possible after application to minimize volatilization losses, reduce odor, and prevent runoff. 3.8 Apply manure uniformly with properly calibrated equipment. 3.9 Time liquid manure applications to match crop nutrient uptake patterns in order to minimize the opportunity for NO3 leaching on coarse textured soils. Effluent application amounts must not exceed the soil water holding capacity of the active rootzone. Several light applications of liquid manure during the growing season are better than a single heavy application. 3.10 Limit solid manure application on frozen or saturated ground to fields not subject to runoff. Liquid effluent should not be applied to frozen or saturated ground. 3.11 Create a buffer area around surface water and wells where no manure is applied to prevent the possibility of water contamination. 3.12 Plant permanent vegetation strips around the perimeter of surface water and erosive fields to catch and filter nutrients and sediments in surface runoff. 3.13 Apply manure on a rotational basis to fields that will be planted to high N use crops such as corn or forage. Long-term annual applications to the same field are not recommended, except at tow rates. Manure Collection and Storage BMPs 3.14 Locate manure stockpiles, lagoons, and ponds a safe distance from all water supply wells. Manure stockpiles, lagoons, and runoff collection ponds should be located on areas not subject to leaching and must be above the 100 year flood plain, unless adequate flood proofing structures are pro- vided. 3.15 Inspect lagoons and liquid manure storage ponds regularly to ensure seepage does not exceed state and local restrictions. 3.16 Divert runoff from pens and manure storage sites by construction of ditches or terraces. Collect runoff water from the lot in a storage pond; minimize Solid manure application runoff volume by diverting runoff water from crossing the feedlot. 3.17 Clean corrals as frequently as possible to maintain a firm, dry corral surface with the loose manure layer less than one inch deep and pen moisture content between 25 percent to 35 percent. Avoid mechanical disturbance of the manure-soil seal when cleaning feedlots. Create a smooth surface with a 3 percent to 5 percent slope when scraping • - lots. 3.18 Scrape feedlots or manure storage areas down to bare earth and revegetate after they are permanently abandoned. 22 —Nutrient Management Plan Guidelines 1. Using Worksheet 1, determine the approximate nutrient inventory from manure production on your farm. If you use manure but do not produce any on your farm go to Worksheet 2. 2. Attach farm maps identifying fields receiving manure, waste storage facilities and natural resource areas of special concern, such as streams, groundwater recharge areas, wetlands, public or private drinking water wells. 3. Fill out 1 copy of Worksheet 2 per field identifying: • cropping sequence • yield expectations • crop nutrient needs • nutrient credits • planned manure and or fertilizer rates • note any special management needed to protect natural resource areas of special concern. 4. Attach soil tests, manure analysis, irrigation water tests, and plant tissue analysis used to determine proper nutrient rates. 5. Use Worksheet 3 to document whole farm nutrient use. —6. Attach information on feed management to reduce nutrients, manure treat- ment to reduce nutrient content or volume, and land management practices used to modify manure loading rates. If other manure utilization options are used, such as composting or sale to other producers, document amount of manure diverted annually. 7. Indicate who prepared forms and date them. 8. Nutrient management plan should be reviewed and evaluated annually. 23 AgPro Environmental Services, L.., 05.31.2002 Appendix E • Soil Testing Protocol • Process Wastewater/Stormwater Testing Protocol • Solid Manure Testing Protocol • Irrigation Water Testing Protocol Highland Dairy Comprehensive Manure& Wastewater Management Plan 16 AgPro Environmental Services, L�..

This supplement outlines management practices generally acceptable and proven effective at minimizing nuisance conditions. Neither nuisance management nor this supplemental plan is required by Colorado State statute or specifically outlined in the Colorado Confined Animal Feeding Operations Control Regulations. This is a proactive measure to assist integration into local communities. These management and control practices, to their best and practical extent, will be used by Highland Dairy. Legal Owner, Contacts and Authorized Persons Correspondence and Contacts should be made to: Highland Dairy Eldon Marrs 875 Condor Road Eaton, CO 80615 303-434-8924 The individual(s) at this facility who is (are) responsible for developing the implementation, maintenance and revision of this supplemental plan are listed below. Eldon Marrs Partner (Name) (Title) Legal Description The confined animal feeding facility described in this NMP is located in: The SW4 and the W2 W2 of the SE4 of Section 17, T8N, R65W, of the 6th P.M., Weld County, Colorado. 2 Highland Dairy AgPro Environmental Services,LLC Air Quality Air quality at and around confined animal feeding operations are affected primarily from the relationship of soil/manure and available moisture. The two primary air quality concerns at dairies are dust and odor. However, the management practices for dust or odor control are not inherently compatible. Wet pens and manure produce odor. Dry pens are dusty. The two paragraphs below outline the best management practices for the control of dust and odors that Highland Dairy will use. The manager shall closely observe pen conditions and attempt to achieve a balance between proper dust and odor control. Dust Dust from pen surfaces is usually controlled by intensive management of the pen surface by routine cleaning and harrowing of the pen surface. The purpose of intensive surface management is twofold; to keep cattle clean and to reduce pest habitat. The best management systems for dust control involve moisture management. Management methods Highland Dairy shall use to control dust are: 1. Pen density Moisture can be managed by varying stocking rates and pen densities. The animals wet manure and urine keep the surface moist and control dust emissions. 2. Regular manure removal Highland Dairy will continue to conduct regular manure removal. Typically, pens are cleaned, conditioned and maintained as needed manure is removed at least annually. 3. Pen Sprinkling Should nuisance dust conditions arise, pen sprinkling may be used for moisture control on pens and internal roadways to minimize nuisance dust conditions. Odor Odors result from the natural decomposition processes that start as soon as the manure is excreted and continue as long as any usable material remains as food for microorganisms. Odor strength depends on the kind of manure, and the conditions under which it decomposes. Although occasionally unpleasant, the odors are not dangerous to health in the quantities customarily noticed around animal feeding operations and fields where manure is spread for fertilizer. Key practices Highland Dairy may use to control odor are: 1. Establish good pen drainage Dry manure is less odorous than moist manure. Maintaining good pen drainage can be achieved by regular cleaning in pens and under fences. The dairy will conduct routine pen cleaning to reduce standing water and remove wet manure. 3 Highland Dairy AgPro Environmental Services,LLC 5. Minimize stockpiles or storage of manure Stockpiles of manure provide both breeding and protective habitat. Keep stockpile use to a minimum. 6. Biological treatments Parasitic wasps are excellent biological fly control and are widely used. The wasps lay their eggs in fly larvae hindering fly reproduction. 7. Baits and chemical treatments Due to environmental and worker's safety concerns, chemical treatments are a last line of defense for insect control. However, they are very effective. Baits and treatments must be applied routinely. Dead Animals Mortality is an unfortunate and unavoidable part of animal husbandry. Dead animals can produce offensive odors, attract scavengers, and create deleterious conditions. Property and timely disposal of dead animals prevents nuisance conditions from occurring. Key practices Highland Dairy may use to handle and dispose of dead animals are: 1. Expedient removal from pens Dead animals will be removed from pens daily and relocated to an area(s) away from the pens. 2. Commercial Rendering Company removal Dead animals will be removed by a commercial rendering company when possible and economically feasible. These practices represent the latest and most modem management and scientific information to date for control of nuisance conditions for the livestock feeding industry. 5 Hello
