This LAP outlines current site conditions, land application practices and monitoring. This LAP will be kept on-site. This LAP is intended to be utilized temporarily, until the land application area reaches an equilibrium with the proposed application amounts. At that time Kerbs Dairy plans to follow "tier two" application practices. Kerbs Dairy will keep records relating to the LAP onsite for a minimum of three years. Contacts and Authorized Persons Brad or Lisa Kerbs 33440 Weld County Rd 55 Gill, CO 80644 (970) 667-2697 The individual(s) at this facility who is (are)responsible for developing and implementation, maintenance and revision of this LAP are listed below: Brad or Lisa Kerbs Owners (Name) (Title) Legal Description The legal description of Kerbs Dairy is: Most of the SW'/4 of Section 15, Township 6 North, Range 64 West, Weld County, Colorado. Site Description and Current Conditions Facility _ Kerbs Dairy is an existing facility located on Weld County Road 55, north and east of the intersection of WCR 55, and HWY 392. The Kerbs Family recently acquired the dairy and are revising and expanding the operation. Previous owners had land-applied liquid and solid manure on the circular sprinkler area in excess of what the growing growing could utilize. Therefore, r excess nitrogen exists within the land application field. This LAP is designed to facilitate the utilization of excess nitrogen within the soil as well as that which will be applied over the next several years. Soils Soils at Kerbs Dairy consist of primarily Nelson fine sandy loam, Otero sandy loam and Thedalund loam. Soils map and detailed descriptions are in Appendix A. The Nelson fine sandy loam is a moderately deep,well-drained soil that formed in residuum from soft sandstone. Typically,the surface layer is light brownish gray fine sandy loam about 9 inches thick. The underlying material is light olive brown fine sandy loam. Soft sandstone is at a depth Kerbs Dairy Comprehensive Nutrient Management Plan 3 AgPro Environmental Services,LLC 03.22.2001 of about 30 inches. Permeability is moderately rapid. Available water capacity is moderate. The effective rooting depth is 20 to 40 inches. Surface runoff is slow to medium and the erosion hazard is low. The Otero sandy loam is a deep well drained soil that was formed in mixed outwash and eolian deposits. Typically, the surface layer is brown sandy loam about 12 inches thick. The underlying material to a depth of 60 inches is pale brown calcareous fine sandy loam. Permeability is rapid. Available water capacity is moderate. The effective rooting depth is 60 inches or more. Surface runoff is slow and the erosion hazard is low. The Thedalund loam is a moderately deep, well-drained soil that formed in residuum from shale. Typically the surface layer is brown loam about 8 inches thick. The underlying material is pale brown and very pale brown loam. Shale is at a depth of about 28 inches. Permeability and available water capacity are moderate. The effective rooting depth is 20 to 40 inches. Surface runoff is medium, and the erosion hazard is low. Maps The maps described below are included in Appendix A. Topographic Map The Topographical Location Map shows the location of Kerbs Dairy, surrounding sites, topography and major drainages. Site Layout The Site Layout details the configuration of the expanded dairy and the land application field. Current Soil Analysis AgPro Environmental Services, LLC has recently tested the soil at Kerbs Dairy for nutrients down to 12 feet from the ground surface. Table 1, below, summarizes the laboratory results of these tests(Laboratory reports are in Appendix B). As shown in the table, testing was performed on the top two feet at one-foot intervals and continuing down to 12 feet at two-foot intervals. The top two feet were tested for pH, soluble salts, organic matter, nitrate, phosphorus and potassium. Horizons below two feet were sampled for nitrate only.

One test was performed in early January and another in mid February of 2001. Kerbs Dairy Comprehensive Nutrient Management Plan 4 AgPro Environmental Services,LLC 03.22.2001 — The early January sample was taken from the long main lagoon on the east end. The mid February sample was taken directly from the incoming water stream as the lagoon was frozen. Table 2, below, summarizes the laboratory results of these tests (Laboratory reports are in — Appendix B). As shown in the table, the process wastewater was analyzed for the major nutrients normally present in dairy process wastewater. Table 2 also demonstrates that the sample taken in mid February was predictably higher than the one taken in early January due to — the sampling location and the incoming process water not having time for treatment and/or volatilization of ammonium nitrogen.

It is calculated that approximately 12 acre-feet of annual land application is required to keep the — process wastewater system in balance to maintain storage for a 25-year, 24-hour storm. Solid Manure Analyses and Current Year's Application — Kerbs Dairy applied some solid manure to the land application site during the past winter. This application was in conjunction with dairy clean-up operations and did not approach normal solid manure application amounts. For conservative purposed here, an application amount of 10 tons — per acre will be assumed. This represents a conservative estimate as visual inspection indicated less than 10 tons per acre. — AgPro Environmental Services, LLC has recently tested the solid manure at Kerbs Dairy for nutrients. One test was performed on a fresh stockpile and another on a more mature stockpile, and more representative of what was land applied. Table 3, below, summarizes the laboratory — results of these tests (Laboratory reports are in Appendix B). As shown in the table, the solid manure was analyzed for the major nutrients normally present in dairy solid manure. Table 2 also demonstrates that the sample taken from the fresh stockpile was predictably higher than the — one taken from the more mature stockpile due to the mature stockpile having more time for —, volatilization of ammonium nitrogen. — Kerbs Dairy will not normally apply solid manure to the land application field. Area farmers will take solid manure off site to utilize on their own farm ground.

Harvesting of the alfalfa will commence during the summer of 2002. Alfalfa has the deep-rooting properties needed to mine the soil for nitrate and remove the deep nitrogen present in the land application field. Kerbs Dairy figures the yield for this year's corn silage to be 25 tons per acre. The alfalfa is expected to yield approximately 4 tons per acre. Nutrient Balance — Utilizing the crops and yields mentioned above, the nutrient content of the process wastewater and the solid manure, and the current nutrient content of the soil, Table 4 was generated to calculate the amount of nitrogen present, applied, and taken out of the ground during the next — four years at Kerbs Dairy. Table 4 shows that during the fourth year an equilibrium is reached, such that the amount of — nitrogen added annually will continue to be approximately 98 pounds per acre and the amount of nitrogen removed will be 180 pounds. Extrapolating the table out to five years will yield total available nitrogen in the soil after crop harvest of approximately 4 pounds. Table 4 is — reproduced in Appendix B extrapolated out to five years. — Kerbs Dairy Comprehensive Nutrient Management Plan 6 AgPro Environmental Services, LLC 03.22.2001 Table 4-Nitrogen Balance

AgPro Environmental Services,LLC 03.22.2001 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. Kerbs Dairy will test soil on land application areas at least annually using protocol in Appendix C. The first year(2001) Kerbs Dairy will test soil twice; the first test has already been conducted, and the second will occur after corn silage harvest. Irrigation Water Testing Kerbs Dairy will test irrigation water once per year using the protocol in Appendix C. Manure, Compost and Stormwater Testing _ Manure, compost 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. Kerbs Dairy will test stormwater/process wastewater prior to land application following the protocol in Appendix C. Record Keeping Records of each wastewater application event will be kept on the Process Wastewater Application Log. These forms are included in Appendix B. Soil, wastewater, and irrigation water testing results will be retained for a minimum of three years. These records associated with manure and nutrient management at Kerbs Dairy will be kept with this LAP.

Samples will be sent to Olsen's Agricultural Laboratory, Inc., McCook, NE. Brad Kerbs will be responsible for notifying AgPro when the silage crop is harvested in the fall of 2001, when alfalfa harvest is occurring, when wastewater is several weeks from application, and during mid-irrigation season, when irrigation water has been running for several days. -` Soil Testing Kerb's 50 acre field on the south east corner of the property will be sampled in the fall of 2001 after corn silage harvest and again each spring prior to wastewater application. A composite of 8-20 cores will be taken at depths of 0-1, 1-2, and 2-10 feet, the latter in 2 foot increments. The first foot will be analyzed for nitrate-N, phosphorus (bicarbonate method), potassium, organic matter, and pH. The remaining samples will be analyzed for nitrate-N only. Samples will be sent to the lab immediately, or air dried and sent as soon as possible. "- Process Wastewater/Stormwater Testing Wastewater from the final storage lagoon will be tested prior to each land application. A sample composite will consist of 6 subsamples taken from all sides of the pond and at a depth of 12-18 inches. The composite sample will be placed in a plastic bottle and either be sent immediately to the lab or be frozen and sent as soon as possible. The sample will be analyzed for total N, organic N, ammonium-N, nitrate-N, phosphorus, potassium, total solids, and moisture. _ Irrigation Water Testing Sampling will be conducted mid-season, and after water has been running for several days. Water will be collected either from the ditch or holding pond, using procedures similar to wastewater testing, or from a spigot at the pivot, after it has run for 5 minutes. A 100 ml sample will be collected and placed in a sterile plastic bottle. It will either be sent immediately to the lab or frozen and sent as soon as possible. The sample will be analyzed for nitrate-N. Forage Testing Forage analysis will be conducted on all harvested crops immediately after harvest. Corn silage will be sampled by Brad Kerbs while the product is being chopped and placed into storage. If harvesting occurs over more than one day, samples will be collected each day. For each day of harvesting, two to four handfuls of chopped product will be collected from each of several loads. A minimum of 15 grab samples will be combined for a composite sample, frozen daily, and sent to the lab as soon as possible. Yield records will be kept by Brad Kerbs. Alfalfa will be sampled using a forage probe immediately after the baling of each cutting. A minimum of 20 bales will be sampled and combined into one composite. Yield records will be kept by Brad Kerbs. Both silage and hay will be analyzed for moisture and crude protein. The % crude protein will be divided by 6.25 to determine%N.
