A soil berm wall 18 inches high and 6 feet wide will be constructed along the west side of the property and inside and adjacent to the existing private road which runs parallel to the west boundary The length of the west berm wall will be +/- 2,640 feet. Additionally a similar berm wall 18 inches high and 6 feet wide will be constructed along the north end of the property on the south side of the existing barbed wire fence. The length of the north berm wall will be +/- 1,000 feet. The calculated "effective" containment volume of the berm wall structure is estimated to be 960,000 cubic feet based on a water retention "area" created by the berm walls in the northwest corner of the property with the dimensions of 800' L X 800' W X 1.5' H. This estimated retention volume capability represents 22.03 acre feet of water. The property's 25 year rainfall runoff is estimated at 3.02 inches (based on 5 CCR 1002-81 charts and data) . The total rain runoff potential for this property (based on the CCR data) is 660,000 cubic feet (2,640 ' x 1000 ' x 0.25 ') or a calculated 15.15 acre feet of runoff volume. The proposed berm wall, therefore, represents a storm water capacity of 145 %. Please refer to the attached Proposed Storm Water Containment System Plat attached to this questionnaire.

First, I have added a paragraph to the specifications on page 20 of the Design and Operations plan regarding mixing of bentonite or bentonite slurry for the lagoon liner. The only practical way to distribute solid bentonite over a large area is via an end-dump truck,spread with a box blade and tractor and incorporated into the lift of soil with a tractor and a disc. Bentonite slurry will be spread with a slurry truck and spread with a box blade and disc as above. We have used these methods for several years. If you have any other ideas, I am interested in helping our client with an easier more practical method. Second,we believe that the method specified in the Design and Operations plan is adequate. However, if you request an undisturbed sample,we believe an in-field concentric-ring infiltrometer test method ASTM D3385 is better that the flex-wall permcameter method ASTM D5084. The concentric ring test will also yield final results faster. Third,we did not designate the ASTM method for nuclear gauge density testing in the Design and Operations plan. However, it is method ASTM D2922 and the plan has been updated to clarify this JULIE Chester- Roger Doak letter 01.doc Page 2 I January 12, 2001 Page 2 • issue. Finally,a Colorado registered professional surveyor will survey the lagoon during construction and after completion to verify liner thickness. A copy of the updated specification page is included. We assume these are your final comments with the Design and Operations plan. If you have any questions on these issues,please contact us at(970) 535-9318. Sincerely, Thomas Haren Environmental Consultant Pc: Cindi Etcheverry,Trevor Jiricek, Weld County Health Department Julie Chester,Weld County Planning and Zoning Tim Smith,StroMo, LLC '.. End: Updated Liner Specifications JULIE Chester- addendum02.doe Page 1 Stormwater Containment Liner Specifications The following letter from Earth Engineering Consultants, Inc. outlines the general testing and construction methodology and procedures for the StroMo,LLC composting facility stormwater ponds. Specific data analysis and site testing will occur before construction and continue throughout construction pending land-use approval from Weld County. All testing and certification documentation will be supervised and certified by a registered professional engineer and forwarded to Weld County and the Colorado Department of Public Health and Environment. The stonnwater pond will be constructed according to the guidelines developed by Earth Engineering Consultants and the specifications outlined below. Bentonite,bentonite well drilling mud, or other suitable clayey soils if found available on site during excavation, of demonstrated low permeability will be tested for standard Proctor moisture-density relationship (ASTM D-698) and for permeability by the falling- head permeability procedure (ASTM D-5856). If bentonite well drilling mud is used, a sample shall be tested for additives other than bentonite commonly found in drilling mud prior to determining suitability, or a reliable or certified letter supplied from the source listing the components or additives in the drilling mud be submitted to the supervising engineer and the Colorado Department of Public Health and Environment for approval prior to use as a liner material. Solid bentonite will be evenly distributed over the area of each successive lift via end- dump or belly dump trucks,spread with a box blade and tractor or motor grader, and incorporated into the lift of soil with a tractor and a construction disc in the volume and quantities determined by the supervising geotechnical engineer and results from the preliminary laboratory liner material tests to achieve the specified hydraulic conductivity. Bentonite slurry will be evenly distributed over the area of each successive lift with a slurry truck, spread with a box blade or motor grader, and incorporated into each lift of soil with a tractor and a construction disc in the volume and quantities determined by the supervising geotechnical engineer and results from the preliminary laboratory liner material tests. The stonnwater pond will be over-excavated and the compacted liner installed to the final finished grade as follows. Liner fill material will be placed in lifts no thicker than 9 inches. Each lift shall be tested for moisture content and compacted to a maximum dry density of 95% standard proctor. Density testing will be conducted in-place using a nuclear moisture density gauge test method ASTM D2922. A minimum of one in-place nuclear moisture-density test will be conducted on each lift for every 1000 square feet of liner fill area. The liner lifts will be installed to achieve a minimum liner thickness of 18 inches. A Colorado registered surveyor will conduct the constructing staking, site grading plan, JULIE Chester-addendum02.doc Page 2 and final lagoon survey and submit a report verifying the base grades and top of liner grades to ensure a minimum liner thickness of 18 inches. Upon completion of field testing and liner lift installation to the finished grade, one final random sample of the compacted liner material shall be sampled using a double-ring infiltrometer test ASTM method D3385. Once the final permeability rate is determined, a final report including field testing data shall be submitted to the supervising engineer and the Colorado Department of Public Health and Environment for final pond liner certification. The stormwater pond and liner will be field supervised and tested in place by Earth Engineering Consultants, Inc. and AgPro Environmental Services, LLC. A registered professional engineer will certify the liner and the results will be submitted to Weld County and the Colorado Department of Public Health and Environment upon completion.

Cherry Creek Dr. S. Denver, Colorado 80246 - 1530 Re: Response to CDPHE Comments Subject: Application for Class III Composting Facility STROMO, LLC 6600 W. 20th St. , # 11 Greeley, Colorado 80634 Dear Roger, I have received your letter dated 21 September, 2000 regarding the above cited project and would offer the following responses to your itemized comments which I would ask be included in the Section 14 Regulatory Review document previously submitted as an addendum to that document. 1. The applicants are aware that a Class III facility does not require a Certificate of Designation (CD). The "Design and Operations Plan" is represented in the document from page 3 of 9 to page 9 of 9. It is our understanding that the requirements for financial assurance would be stipulated by the CDPHE at the time the "Application Document" was reviewed. Please advise us as to what the amount of the surety bond is required to be. 2) The name, address, and telephone number of the owner of the facility is; Mr. John Moser 6600 W. 20th St. , # 11 Greeley, Colorado 80634 (970) 330 - 3474 However, the emergency contact details provided in the application in the "Design and Operations Plan" section on page 3 of 9 indicates that the emergency contact person is Mr. Tim Smith, the manager of the facility. 3) The maximum time that raw manure will be temporarily stockpiled prior to being placed in windrows will be 2 weeks. Office: 303/823-9091 Mobile: 303/548.7085 Fax: 303/823-9091 yyy EXHIBIT Serving Industry with Enviromentut Soulutinn.s Since 1982 / / Mr. Roger Doak October 2, 2000 Page Two 4) The "nearby well" referred to on page 7 of 9 of the Operations Plan is identified in the "Vicinity Map" portion of the plat map and is described as a "domestic well". This well is located in the SW/4 of the NW/4 of section 26 and is not shown on the larger scale drawing because it is not located in the area being permitted for a compost facility. It's relevance to the application lies in the fact that it is down-gradient to the site and will serve as excellent monitoring well for the facility. The depth to ground water in this well is reported at 40 feet BGL Since shallow ground water can fluctuate significantly during any given season, we chose to report the last measured depth to groundwater. If necessary, we will provide a current measurement of ground water depth for this application. 5) The elements of a "Fire Protection Plan" were reviewed by the project engineer and Mr. Wes Scott, Manager of the Platteville/Gilcrest Fire Protection District. The specific elements which Mr. Scott suggested should comprise the "Fire Protection Plan" are as follows; a) Access to the site should be clearly marked by signage posted at the main entrance. The signage should identify the Platteville/Gilcrest Fire Protection District as the designated "Fire Suppressor Provider" for the site, the business hours phone number for the district, as well as the "911" emergency contact number. b) The site service road should provide easy access to all areas of the site being used for the composting process and allow for fire engine turnarounds within the site. NOTE: Since no buildings are planned for construction at the site nor are any employees of the applicant required to be at the site on a permanent basis, no other special requirements or elements were required by Mr. Scott in preparation of the "Fire Protection Plan". 6) The distance of "designated/linear intervals" for windrows is 20 feet. The approximate size of the windrows as noted on page 4 of 9 in section "C" is 10 feet wide and 3 feet high. The length of any individual windrow will vary from 200 feet to 600 feet. 7. Nuisance conditions control will be handled as follows; FLIES: On-Site: a) the presence of flies will be minimized by frequently turning the windrow piles of manure waste to avoid anaerobic conditions which tends to produce pockets of decayed wastes which, in turn, attracts flies. Additionally, the fly population will be controlled through the use of spray/mist equipment using EPA approved chemicals to treat the surface areas of the site where flies are observed to congregate. Off-Site: a) If flies are observed to be originating at the subject site and move offsite; fly bait traps will be placed along the perimeter of the site to minimize off-site migration. Mr. Roger Doak October 2, 2000 Page Three Nuisance conditions control will be handled as follows Cont'd: ODOR: On-Site: a) odors associated with the composting process will be minimized by frequently turning the windrow piles in order to introduce oxygen into the waste mass and accelerate the bio-degradation of the waste manure which in turn will minimize odors in the compost mass. Off-Site: a) See "a" above. 8. Reference to the retention pond being located in the "northeast" corner of the site was a typographical error. The retention pond is to be located in the northwest corner of the site as described on page 4 of 9. 9. Interim Closure Plan - In the event the facility ceases operation for more than 90 days, the following procedure will be followed to de-activate the site; a) All existing composted manure will be removed from the site and applied in a land farming operation off- site. b) Any remaining raw manure or other materials used as filler or blending agents will be removed from the site and disposed of either through approved recycling techniques or by commercial disposal at an approved Class II disposal site. 10. The following requirements will be added to the "Description of Surface Water Control System" segment of the "Application Document"; a) The retention pond structure will be constructed of low permeability materials (clay soil or commercial bentonite) that will achieve a hydraulic conductivity of less than or equal to 1 X 10 Am/sec. b) The retention pond structure will be de-watered within 15 days of a storm event so that the full runoff storage capacity is restored and the hydraulic head is removed. The leachate/storm water will be pumped from the retention pond structure to a dryland pasture located to the east and upgradient to the site through irrigation sprinklers. c) The surface water control system is designed to prevent storm water flow from backing up onto the windrow area of the site during the 25-year storm event. Mr. Roger Doak October 2, 2000 Page Four If possible, please include the above cited responses to your September 21st review letter as an "addendum" to the originally submitted document. However, if you would prefer that we re-submit the regulatory review document related to Section 14 and entitled "Applicability of Solid Waste Composting Regulations" with the above noted revisions added to the document please advise at yourearliest convenience.

The thickness of the Aquifer is unknown. (6) Hydrologic Properties of Uppermost Aquifer. Unknown (7) Quality of Ground Water Beneath Site: Unknown. A sample of the water from the nearby water well will be collected and tested if required by the CDPHE. (8) Types & Regional Thickness of Unconsolidated Bedrock: Based on core data generated during water well drilling activities, the principal type of bedrock is a claystone/shale. The thickness of the bedrock is estimated at 6-12 feet. (9) Geologic Hazards: None Plans for interim and final closure of the site: CDPHE Ref: 14.4.2(J) See Section 14.6 for details Contingency Plan for Corrective Actions: CDPHE Ref: 14.4.2(K) The shipping/receiving procedures described in 14.4.2(E)(A) are intended to discourage the (1) Presence of any CDPHE "unapproved wastes". (2) The protection of any shallow ground water will be accomplished by constructing the compost pads with a 3 % slope to enhance surface water runoff to be directed to the storm water retention area in the northeast corner of the site. Additionally, pumping of any accumulated storm water to the adjacent cultivated field to the west will further prevent any tendency for the accumulated water to percolate downward in the direction of any shallow ground water. (3) Nuisance Conditions including odor and/or flies will be minimized by properly managing the compost piles as described in the operations section of this document. Fire Protection Plan CDPHE Ref: 14.4.2(L) A Fire Protection plan will be submitted to the Platteville Fire Protection District as one of the requirements of the Weld County USR application. STROMO, LLC COMPOST FACILITY DESIGN AND OPERATIONS PLAN PAGE 8 OF 9 Low Permeability Work Pad: CDPHE Ref: 14.4.3 Given the type of soils and the degree of slope existent at the site, it is the opinion of the site engineer that the precautions and concerns articulated in this section of the regulations has been properly reviewed and resolved. Ground Water Monitoring Waiver. CDPHE Ref: 14.4.4 The USR document previously submitted to the Weld County Planning Department discusses the monitoring of ground water by using the existing domestic water well located adjacent to the site and down gradient as the primary source for ground water sampling. That plan describes, as a contingency, the installation of additional monitor wells if any contaminants are found in the domestic water well as a result of periodic sampling and testing of the well water. STROMO therefore requests a waiver to the requirement to install monitor wells at this site until or unless circumstances warrant such action. Management of the Compost Piles: CDPHE Ref: 14.5.4(A) (1) The density of the fecal coliform present in the compost shall be maintained at less than 1000 Most Probable Number per gram of total solids (dry weight basis); or (2) The density of Salmonella sp. bacteria in the compost shall be maintained at less than three (3) Most Probable Number per four (4) grams of total solids (dry weight basis) at the time the compost is to be sold or otherwise distributed for use. NOTE: To comply with 14.4.5(A) of the regulations, a sample of the compost windrow subsequent to the blending of bulk materials with the manure will be taken in procedures described in the attached document entitled "SAMPLING/ANALYSIS PROCEDURES". If the fecal coliform density exceeds the regulatory level, additional bulk materials will be added to the compost pile to reduce the density number to the target level. During the compost process stage, the SOLVITA Maturity Index procedure will be used to monitor the maturity stage of each compost pile. Data generated by the SLOVITA protocol include CO2 rate and ammonia levels (NH3) in the compost mass and provides guidelines for manipulating these constituents to enhance the compost process. A copy of the SLOVITA testing guidelines are provided as an attachment to this document entitled "Guide to SLOVITA testing for compost maturity index" and is located in the "Appendix Section". STROMO, LLC COMPOST FACILITY *********eat*******.,*******„******,* DESIGN AND OPERATIONS PLAN PAGE 9 OF 9 Management of the Compost Piles: CDPHE Ref: 14.5.4(B) Compliance with 14.4.5(B) is to be accomplished by maintaining the in-process compost pile at a temperature of 55 degrees Celsius (131 degrees Fahrenheit) or higher for 15 days or longer. During the period when the compost is maintained at 55 degrees Celsius or higher, there shall be a minimum of five (5) turnings of the windrow. Procedures for sampling and testing are previously described for in the attached document entitled "SAMPLING/ANALYSIS PROCEDURES". Closure Plans: CDPHE Ref: 14.6 14.6.1 & 2: It is not anticipated that the site will experience some interim period of non-use. 14.6.3 & 4 Since no permanent structures will be constructed at the site, closure of the site at the conclusion of composting operations will consist of removing all compost and bulk materials from the site; discing of the surface areas used for composting, and re-seeding of the impacted site with a dryland pasture grass mix to be drilled in. Additionally, a straw mulch will be lightly disced into the seed bed along with a separate seeding of the area with a cover crop of winter rye or oats to minimize soil erosion during the grass germentation/maturation stage. Post Closure Care and Maintenance: CDPHE Ref: 14.7 A. Following closure of the facility, a notation will be placed on the deed notifying any potential purchaser that the property has been used as a composting facility. B. The post closure care and maintenance shall be for (5) five years and shall consist of: (1) the continued monitoring and sampling of groundwater or surface water. (2) inspection and maintenance of any cover material or vegetation. Submitted by: L.C.

It is based on measuring carbon-dioxide respiration and ammo- nia content simultaneously in the same test. Each test alone provides important clues to compost quality, and used together provide valuable information to judge the condition and safety of any composted product. Compost Maturity is a term that has been used in a variety of ways.The Solvita Maturity Test ranks your compost on a 1-to-8 index scale of increasing maturity. Maturity means resistant to further decomposition and free of compounds such as ammonia and organic acids which can be toxic to plant growth The Solvita test can be used effectively for the following purposes: 1)Evaluating compost conditions in order to make improvements to the compost process; 2)Establishing compost maturity for marketing reasons and to determine the best end-use prior to distribution and sales. Solvita Compost Testing: 3 Steps to Satisfactory Results There are three easy steps involved in using the Solvita test kit to evaluate compost. A-Obtain and prepare the sample. B- Perform the test by placing both Solvita gel-paddles in the jar. Use enclosed Color Keys to find the appropriate color numbers. Use the simple computation table to determine your compost's Maturity Index. C- Interpret the results. Once you know the maturity index, consider the process management and desired end use of your compost. Use the tables in the manual as well as the troubleshooting section to evaluate the process and determine the best use. TIPS ABOUT HANDLING THE SOLVITA KIT All Solvita kits are carefully packaged at the factory to insure highest quality prior to ship- ping.The gel-paddles should be the"Control Color"when the foil pack is opened(see color chart). If the foil packs have been punctured or damaged, or the jar cracked in any way, then the test may not work properly. Store at room temperature and use within the indi- cated time period. Shelf-life is significantly extended by refrigerating the un-opened foil packs. Do not allow to freeze.

OVERVIEW: The primary source of animal manure waste will be generated by MORWAI Dairies. Each load of manure received at the compost site will be logged into a traffic journal maintained at the compost site. The manure received will be either stockpiled in the receiving area or dumped directly into a compost row where bulking materials will be blended with the manure mass. There will be two stages of sampling/analysis conducted at the compost site. II. Initial Sampling/Analysis Procedure: A. Sampling Procedure: Once the manure wastes are windrowed but prior to blending with bulking materials, random grab samples of the manure waste will be collected at designated linear intervals from one end of the row to the other end. Each grab sample should consist of +/- 1/2 pound of sample material and should be placed in one or more clean plastic 5 gallon pails. The grab samples will then be thoroughly blended in a large plastic tub. Once the sample mass has been successfully homogenized, a 1 pound composite sample will be collected and placed in a 1 gallon zip lock plastic bag; placed in a iced or refrigerated cooler; and delivered within 8 hours to a designated laboratory with a "chain of custody' document completed for each sample submitted (several samples may be entered on to a single document form. B. Analysis Procedure: The composite sample will be submitted for laboratory analysis to determine the following constituent concentrations; - Moisture (%) - Nitrates (ppm) - Nitrogen (%) - pH - EC (salts) - Organic Matter[(%) & (carbon:nitrogen ratio)] The test results for each sample submitted will entered into a "Lab Analysis" log book for future reference. NOTE: Based on the lab data generated during the initial sampling/analysis stage, the raw manure waste will be mixed with bulking materials, water, and/or other nutrients to accelerate the bio-degradation process. After subsequent cyclical rotations (turnings) and other treatment of the windrowed manure mass has been completed, the second stage of sampling analysis will be accomplished. STROMO, LLC COMPOST FACILITY SAMPLING/ANALYSIS PROCEDURE Page 2 of 3 Ill. Final SamplinglAnalysis Procedure: A. Sampling Frequency: In compliance with 14.5.2 of the CDPHE regulations, "(A) Finished compost will be sampled and tested once every 20,000 cubic yards of compost produced or annually, whichever is more frequent; and (B) Finished compost which has been sampled and tested, but to which additional feedstock is added prior to, or during distribution, shall be re-sampled and re-tested prior to commencing or continuing distribution". A. Sampling Procedure: In compliance with 14.5.3 of the CDPHE regulations, the following sampling procedure will be implemented to " assure valid and representative analytical results": Once the compost operations supervisor determines that an individual windrow of processed manure waste appears to have completed the bio-degradation cycle, random grab samples of the processed material will be collected at designated linear intervals from one end of the row to the other end. Each grab sample should consist of +/- 1/2 pound of sample material and should be placed in one or more clean plastic 5 gallon pails. The grab samples will then be thoroughly blended in a large plastic tub. Once the sample mass has been successfully homogenized, a 1 pound composite sample will be collected and placed in a 1 gallon zip lock plastic bag; placed in a iced or refrigerated cooler; and delivered within 8 hours to a designated laboratory with a "chain of custody' document completed for each sample submitted (several samples may be entered on a single document form.

Weld County, Colorado Dear Julie, As you are aware, John Moser, Ron Ditson (John's farm manager) and I met with Trevor Jericek and Cindi Etcheverry to discuss to the phase down of an existing compost facility which is currently being operated without a permit and the initiation of a USR application for a proposed compost facility to be operated at a different location. In developing a USR for the ENVIRO Cycle facility last year, it was extremely helpful for me to submit the various documents required by the USR process in a package for preview to you and Trevor prior to submittal of the formal USR package. This brief preview of the prepared documents allows me to make any needed corrections to the documents and saves you and Trevor the time to write letters requesting corrections to those documents. As of this date, the USR application package lacks a recorded deed for the subject property and the completed 24" X 36" scaled "Special Review Plat Map". However, given the stipulated time deadline of March 31, 2000 established by agreement in Treavor's 10 March letter, a copy of which you have, - I trust that this submittal of the USR application for review purposed will honor that deadline. I will attempt to contact both you and Trevor on Thursday morning to arrange for a brief meeting to review the USR documents I have completed and to receive any additional directions you or Trevor is necessary in order to expedite this USR application.

Compost Feedstock Types (14.1.4) The proposed facility intends to receive, treat, and compost Type 1 described as "agricultural crop residues, manure, and untreated wood wastes source separated yard, paper and green wastes". Facility Classification (14.1.5) The proposed facility conforms with the Class III composting facility: • Only Type 1 feed stocks may be received which include agricultural crop residues, manure, untreated wood wastes, source separated yard, paper and green wastes • feed stocks from several generators may be accepted for processing • < 50,000 cubic yards of feedstock in-process or bulking materials onsite at any one time • A Certificate of Designation is not required Minimum Standards of Operation for All Composting Facilities (14.2) Section 14.2.1 (A) The facility will control surface water flowing onto the site by a series of ditches and/or berms located along the upgradient boundaries of the composting areas. The runon water will be directed around the facility and will not be contained within the stormwater containment structure. The stormwater from the composting site that has been in contact with raw composting material or compost in various stages will be collected in a stormwater containment structure located in the northwest corner of the composting site. The stormwater structure will be designed to contain stormwater from a 25-year, 24-hour storm event subject to the runoff factors applied to the surface texture, contour and slope of the compost drainage area. The stormwater structure will be lined with impermeable clay, bentonite or other acceptable material and designed to limit seepage to a maximum seepage rate of 1 x 10 -s cm/see. Containment and liner construction.will be conducted under the supervision of a Registered Professional Engineer in the State of Colorado. The liner will be tested in place and results of the liner certification submitted to the Colorado Department of Public Health and Environment. Additional storm water construction standards, specification and testing procedures are outlined in the Section "Description of Surface Water Control System". AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 11 (B) The proposed facility will control onsite and offsite nuisance conditions such as noise, dust, odor, flies and windblown debris by best management practices outlined in the nuisance management section of this operations plan. (C) Prevent water pollution at or beyond the site boundaries. Offsite water pollution will be prevented by control structures to prevent run-on and to contain runoff are included in detail in this plan. Additionally, three groundwater-monitoring wells will be used to monitor the groundwater surrounding the composting site. (D) Gates, signs and fences to prevent illegal dumping at the facility will be used to control access. Additional details regarding site access control are outlined in the following sections of this plan. Record keeping and Annual Reporting Requirements (14.2.2) (A)The proposed Class III facility will submit, annually on May 1“ of each year, a report to the CDPHE and Weld County providing the total cubic yards of material received at the facility during the previous calendar year including by type: (1) The quantity of finished product used onsite, sold, or distributed offsite. (2) The quantity and type of feedstock and bulking materials received, processed and remaining onsite. (3) The quantity of finished compost remaining on site. (B)The proposed Class III Compost Facility shall maintain, at a minimum, the following applicable records: (1) Type and amount of feedstock(s) and bulking material(s) received, processed, and remaining onsite; (2) Amount of finished compost sold or distributed offsite; (3) Water quality monitoring data; (4) Compost analytical data; (5) Operational monitoring data including; time and temperature readings; (6) Windrow/Pile aeration data; (7) Financial assurance documentation; (8) Design and operations plan; These records will be maintained at the facility and will be available for review by Weld County or the CDPHE. Financial Assurance (14.3) A Certificate of Deposit (CD) has been established according to Section 1.8, Financial Assurance Criteria and Appendix A, Financial Assurance Instrument Language, for the estimated closure sum of$15,000. The closure requirements and estimates include $9,000 for site restoration activities. A letter from MBR, Inc., a Colorado Company, is included outlining the estimated site restoration costs.

Haren December 1, 2000 AgPro Environmental Services, LLC 4311 Highway 66, Suite 4 Longmont, CO 80504 Subject: Cost Estimates Dear Mr. Haren, The following outlines the estimated work and . 1) Removal of Residual Materials from Facility: All raw composting materials, manures and residual materials (sawdust, crop residues, etc.) used in the composting process will be removed from the site and sent to another approved composting facility or permitted solid waste facility as necessary or incorporated into adjacent fields by plow cultivation in an agronomic manner according to Colorado State University, Cooperative Extension fertilization recommendations. 2) Removal of Compost Debris from Surface Soils in Windrow Areas: After the windrow area of the facility has been cleared of all composting material, the shallow surface area will be scalped to remove the compost "hard pan" layer that typically develops over extended periods of processing. This compost hard pan residue will be removed from the site and also incorporated into adjacent fields by plow cultivation similar to paragraph 1 above. 3) Stormwater and Containment Structures: Any stormwater accumulation in the stormwater containment structure will be dewatered onto adjacent farmground in an agronomic manner according to Colorado State University, Cooperative Extension fertilization recommendations. Residual solids accumulations in the structure will be removed and land applied along with the surface soils from the composting areas as outlined in paragraph 2 above. The containment structure will be leveled and the ground returned to an original state prior to construction and operation. �...,3 HIOHI A 60 •Loric,moNi COLORADO 80504 •(303) 449-0445•4243286•FAX I-970-535-4519 4) Re-Contouring of Subject Site: All roads, ditches, berms, earthen diversion and containment structures will be graded back into the "cut area" from which it was generated to re-establish original surface contours. A laser leveling instrument will be used to tie in the re-contoured areas with original grades and contours. 5) Re-Seeding of Disturbed Surface Area: The disturbed surface area will be prepared by disking to produce a seedbed. A dry land grass pasture mix including a winter rye or oats cover crop seed will be drilled into the prepared seedbed. The newly seeded area will be fenced off from use for a time period adequate to allow the grass seed to germinate and become established. We estimate the total cost for implementation for the closure of the proposed facility as outlined above is $9,000.00. Sincerely, John Miskol, President An additional $6,000 is estimated for post closure groundwater monitoring. Water samples from the proposed down gradient monitoring wells will be sampled on a quarterly basis and analyzed for the following: Nitrates Electra Conductivity (EC) Total Dissolved Solids Salts PH RCRA Metals Potassium Phosphorus This monitoring program will be conducted for a period of five years. If year one anaysis inidicates groundwater contaminants are not present, a request to terminate subsequent years 2 through 5's groundwater sampling will be submitted to the CDPH&E. The estimated cost for completion of this task is $6,000.00. - A copy of the Certificate of Deposit financial instrument and letter from American Ag Bank is included in the following pages.

Runon controls will be sized to divert runon water from up to a 25-year, 24-hour storm event around the composting facility and containment structure. The stormwater from the composting site that has been in contact with raw composting material or compost in various stages will be collected in a stormwater containment structure located in the northwest corner of the composting site. The stormwater structure will be designed to contain stormwater from a 25-year, 24-hour storm event subject to the runoff factors applied to the surface texture, contour and slope of the compost drainage area as outlined in the Natural Resources Conservation Service Service Manual Field Guide, Section 4; Hydrology. The stormwater structure will be lined with impermeable clay, bentonite or other acceptable material and designed to limit seepage to a maximum seepage rate of I x 10 ` cm sec, Containment and liner construction.will be conducted under the supervision of a Registered Professional Engineer in the State of Colorado. The liner will be tested in place and results of the liner certification submitted to the Colorado Department of Public Health and Environment. Stormwater collected in the containment system will be dewatered within 15 days to a level necessary to hold a complete 25-year, 24-hour storm event. The stormwater will be used on the compost when necessary to facilitate the composting process or land applied on 160 acres of available adjacent farmground in an agronomic manner according to the Best Management Practices identified by Colorado State University, Cooperative Extension guidelines. AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 19 Stormwater Containment Liner Specifications The following letter from Earth Engineering Consultants, Inc. outlines the general testing and construction methodology and procedures for the StroMo, LLC composting facility stormwater ponds. Specific data analysis and site testing will occur before construction and continue throughout construction pending land-use approval from Weld County. All testing and certification documentation will be supervised and certified by a registered professional engineer and forwarded to Weld County and the Colorado Department of Public Health and Environment. The stormwater pond will be constructed according to the guidelines developed by Earth Engineering Consultants and the specifications outlined below. Bentonite, bentonite well drilling mud, or other suitable clayey soils if found available on site during excavation, of demonstrated low permeability will be tested for standard Proctor moisture- density relationship (ASTM D-698) and for permeability by the falling-head permeability procedure (ASTM D-5856). If bentonite well drilling mud is used, a sample shall be tested for additives other than bentonite commonly found in drilling mud prior to determining suitability, or a reliable or certified letter supplied from the source listing the components or additives in the drilling mud be submitted to the supervising engineer and the Colorado Department of Public Health and Environment for approval prior to use as a liner material. Solid bentonite will be evenly distributed over the area of each successive lift via end-dump or belly dump trucks, spread with a box blade and tractor or motor grader, and incorporated into the lift of soil with a tractor and a construction disc in the volume and quantities determined by the supervising geotechnical engineer and results from the preliminary laboratory liner material tests to achieve the specified hydraulic conductivity. Bentonite slurry will be evenly distributed over the area of each successive lift with a slurry truck, spread with a box blade or motor grader, and incorporated into each lift of soil with a tractor and a construction disc in the volume and quantities determined by the supervising geotechnical engineer and results from the preliminary laboratory liner material tests. The stormwater pond will be over-excavated and the compacted liner installed to the final finished grade as follows. Liner fill material will be placed in lifts no thicker than 9 inches. Each lift shall be tested for moisture content and compacted to a maximum dry density of 95% standard proctor. Density testing will be conducted in-place using a nuclear moisture density gauge test method ASTM D2922. A minimum of one in-place nuclear moisture-density test will be conducted on each lift for every 1000 square feet of liner fill area. The liner lifts will be installed to achieve a minimum liner thickness of 18 inches. A Colorado registered surveyor will conduct the constructing staking, site grading plan, and final lagoon survey and submit a report verifying the base grades and top of liner grades to ensure a minimum liner thickness of 18 inches. AgPro Environmental Sendees, LLC Your "Pro Ag"Environmental Professionals 20 Upon completion of field testing and liner lift installation to the finished grade, one final random sample of the compacted liner material shall be sampled using a double-ring infiltrometer test ASTM method D3385. Once the final permeability rate is determined, a final report including field testing data shall be submitted to the supervising engineer and the Colorado Department of Public Health and Environment for final pond liner certification. The stormwater pond and liner will be field supervised and tested in place by Earth Engineering Consultants, Inc. and AgPro Environmental Services, LLC. A registered professional engineer will certify the liner and the results will be submitted to Weld County and the Colorado Department of Public Health and Environment upon completion.

Longmont, Colorado 80504 Attu: Mr. Thomas Haren Re: Stormwater Detention Pond Liner Recommendations Stromo LLC Composting Site Hudson, Colorado EEC Project No. 1015006A Mr. Haren: Earth Engineering Consultants, Inc. (EEC) personnel have prepared general guidelines for preparing and testing a low permeability liner for a stormwater detention pond for the referenced project. We understand Stromo LLC is a manure composting facility near Hudson, Colorado. One pond with an approximate area of 3 to 4 acres will be constructed at the composting facility for stormwater detention. Our general guidelines for the preparation and quality control testing for a low-permeability pond liner are provided below. For development of a low permeability pond liner for the referenced project, a suitable liner material should first be selected. We understand that drilling mud will be used as a low-permeability liner. In order to verify the suitability of the drilling mud for use as a liner material, that material should be sampled and tested for standard Proctor moisture- density relationship (ASTM D-698) and for permeability by the falling-head permeability procedure (ASTM D-5856). Once the material's permeability is deemed suitable at a 'target' moisture and density, usually 95% of the materials maximum dry density as determined by the standard Proctor procedure, project specifications can be developed requiring that the target moisture and density be obtained in the field as the liner is being placed. Project specifications also require a minimum pond liner thickness be installed, usually 18 inches. The fill materials should be placed in lifts which allow for full depth compaction; loose lifts no thicker than 9 inches are typically required. During the placement of the pond liner materials, the newly compacted liner materials should be tested for moisture content and in-place density using a nuclear moisture- density gauge to verify that the project specifications are being met.

Principal Engineer Evaluation of potential impact to surface and ground water (14.4.2 (1)) Site Geological and Hydrogeological Conditions: Geological Conditions: In previous site investigations in the same area related to remediation of a crude oil flowline leak in 1990, the shallow geology of the site was identified to a depth of +1- 16 feet. These geologic investigations indicate that there are at least two separate impermeable layers of clay loam which overlay and protect the sandy gravel located below. The first clay bed is located at 5 feet below ground surface and the second at 10 feet below ground surface. During the site investigation period, the sandy gravel section was dry. A cross section of the geologic profile is.provided as an attachment to this document entitled "Site Geological and Hydrogeological Data" and located in the "Appendix Section". The USDA, Soil Conservation Service Classification of Weld county Soils Survey, 1980 indicates the surface soils as valent sands from 0 to 3 percent slopes and 3 to 9 percent slopes. Valent sands are described as deep, excessively drained brown sands. Hydrogeological Conditions: The proposed site is not located within a "Aquifer Recharge Area" as evidenced by a review of the "Weld County Aquifer Recharge Area" map which was produced from data provided by the Colorado Land Use Commission. A copy of a portion of this map is provided as an attachment to this document entitled " Site Geological and Hydrogeological Data" and is located in the "Appendix Section". The nearest surface water is represented by the East Neres Canal which runs in a northeasterly direction and crosses to the west of Section 26. This canal is located greater than % mile from the proposed site and upgradient to the proposed site. Milton Reservior is located approximately 1 '/ miles north of the site. A registered domestic groundwater well is located north and west of the site approximately '/ to 93 of a mile downgradient of the composting facility. Groundwater monitoring wells will be installed between the facility and the domestic well. The monitoring wells will be sampled and analyzed as outlined in the Groundwater Monitoring Section of this plan. Proximity to Floodplain: • The proposed site is not located in any floodplain as evidenced by a review of the "Hydrologic Unit Map" — State of Colorado. A copy of a portion of this map is attached to this document and is located in the "Appendix Section". AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 23 Public Water Supply: No public water supply wells, springs, or surface water intakes exist within one mile of the proposed site. Identification of all Surface waters: No surface waters are located within 'A mile of the proposed site. Depth for Uppermost Aquifer & Thickness The depth to the uppermost aquifer is 40 feet below land surface based on well data dating to 1964. A review of the State Engineer's office well records do not identify a lower confining layer in the subject site and adjacent site's well records. The thickness of the Aquifer is unknown. Hydrologic Properties of Uppermost Aquifer: Unknown Quality of Ground Water Beneath Site: Groundwater samples from irrigation wells located approximately 1 '/z miles west of the site indicate exteremely high concentrations of total dissolved solids (salts) and groundwater nitrates in the 20 parts-per-million range. This is almost double the EPA recommended 10 parts-per-million nitrate levels for human consumption. Types & Regional Thickness of Unconsolidated Bedrock: Based on core data generated during petroleum well drilling activities, the principal type of bedrock is a claystone/shale. The bedrock is located between 40 and 80 feet below grade in the subject site vicinity. The thickness of the bedrock is estimated at 6-12 feet. Geologic Hazards: Weld County geologic hazards maps and data from the Colorado Geologic Service do not identify any geologic hazards in the subject site area. Plans for interim and final closure of the site 14.4.2(J) In the event that it becomes necessary to close the proposed composting facility including the discontined receipt, processing and sale of materials for more than 180 days , or otherwise approved by the CDPH&E, the site will be returned to its original condition. The CDPH&E will be notified of closure activities and when closure is complete. Closure activities at the facility will not exceed 90 days without a prior written extensions granted by the CDPH&E. No permanent structures are planned for the site. All gates, fences and signs will be removed. The following closure tasks are expected: AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 24 1) Removal of Residual Materials from Facility: All raw composting materials, manures and residual materials (sawdust, crop residues, etc.) used in the composting process will be removed from the site and sent to another approved composting facility or permitted solid waste facility as necessary or incorporated into adjacent fields by plow cultivation in an agronomic manner according to Colorado State University, Cooperative Extension fertilization recommendations. 2) Removal of Compost Debris from Surface Soils in Windrow Areas: After the windrow area of the facility has been cleared of all composting material, the shallow surface area will be scalped to remove the compost "hard pan" layer that typically develops over extended periods of processing. This compost hard pan residue will be removed from the site and also incorporated into adjacent fields by plow cultivation similar to paragraph 1 above. 3) Stormwater and Containment Structures: Any stormwater accumulation in the stormwater containment structure will be dewatered onto adjacent farmground in an agronomic manner according to Colorado State University, Cooperative Extension fertilization recommendations. Residual solids accumulations in the structure will be removed and land applied along with the surface soils from the composting areas as outlined in paragraph 2 above. The containment structure will be leveled and the ground returned to an original state prior to construction and operation. 4) Re-Contouring of Subject Site: All roads, ditches, berms, earthen diversion and containment structures will be graded back into the "cut area" from which it was generated to re-establish original surface contours. A laser leveling instrument will be used to tie in the re-contoured areas with original grades and contours. 5) Re-Seeding of Disturbed Surface Area: The disturbed surface area will be prepared by disking to produce a seedbed. A dry land grass pasture mix including a winter rye or oats cover crop seed will be drilled into the prepared seedbed. The newly seeded area will be fenced off from use for a time period adequate to allow the grass seed to germinate and become established. 6) Post Closure Ground Water Monitoring: Water samples from the proposed down gradient monitor well will be sampled on a quarterly basis and analyzed for the following: Nitrates Total Dissolved Solids Salts Electro Conductivity (EC) PH Potassium Phosphorus RCRA Metals AgPro Environmental Services, GLC Your "Pro Ag"Environmental Professionals 25 This monitoring program is planned for a period of five years. Evaluation of analytical results after year one will further define the need for continuing for all of years 2 through 5. Contingency Plan for Corrective Actions 14.4.2(K) The shipping/receiving procedures described in 14.4.2(E)(A) are intended to discourage the (1) Presence of any CDPHE "unapproved wastes". Deliveries to the site will be from known sources and routine suppliers. Unexpected deliveries from unkown sources are not planned. Should an unapproved waste be inadvertently brought to the site, the deliverer will not be allowed to unload and will be required to leave the premises. (2) The protection of any surface water or shallow ground water will be accomplished by constructing the compost pads with a 3% slope to enhance surface water runoff to be directed to the storm water retention area in the northeast corner of the site. Additionally, pumping and application at agronomic rates of any accumulated storm water to the adjacent cultivated field to the west will further minimize the accumulation of water and potential for contamination (3) Nuisance Conditions including odor and/or flies will be minimized by applying best management practices in the composting area and to the compost piles as described in the nuisance management sections of this document. Additional Details on Nuisance Control 14.4.2(K) This Management Plan for Nuisance Control has been developed and implemented to identify methods StroMo, LLC, will use to minimize the inherent conditions that exist in composting operations. This supplement outlines management practices generally acceptable and proven effective at minimizing nuisance conditions. These management and control practices, to their best and practical extent, will be used by StroMo, LLC. The four potential sources for nuisance conditions at the proposed site are dust, flies, odors, and windblown debris. These nuisance conditions control will be handled as follows: Air Quality Air quality at and around composting operations are affected primarily from the relationship of soil/manure and available moisture. The two primary air quality concerns at composting operations are dust and odor. However, the management practices for dust or odor control are not inherently compatible. Wet surfaces and manure produce odor. Dry surfaces and manure dusty. The two paragraphs below outline the best management practices for the control of dust and odors that StroMo, LLC will use. The manager shall closely observe conditions and attempt to achieve a balance between proper dust and odor control. Dust Dust control will be accomplished by wetting down the access roads and facility roads as necessary to minimize fugitive dust at the site and migrating fugitive dust off-site. Dust from surfaces is AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 26 usually controlled by intensive management of the surface by routine cleaning and harrowing of the surface. The purpose of intensive surface management is twofold; to mix dry and moist surfaces and to reduce pest habitat. The best management systems for dust control involve moisture management. Management methods StroMo, LLC shall use to control dust are: Windrow density Moisture can be managed by varying windrow densities. The compost's.moisture content keeps the surface moist and control dust emissions. Regular manure composting StroMo, LLC will incorporate raw manure into the composting operation within 72 hours. Open areas will be harrowed several times per month. This will maintain the surface of the composting operation and level wheel tracks and loader gouges. Sprinkling Should nuisance dust conditions arise, sprinkling may be used for moisture control on surfaces 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 manure composting operations. On-Site: Odors associated with the composting process will be minimized by frequently turning the windrow piles as needed in order to introduce oxygen into the waste mass and accelerate the bio- degradation of the waste manure which in turn will minimize odors in the compost mass. Off-Site: In the event, off-site odors are detected; biofilters or other masking materials will be utilized to mitigate the odor migration problem. Key practices StroMo, LLC may use to control odor are: Establish good surface drainage Dry manure is less odorous than moist manure. Manure will be incorporated into compost within 72 hours of arrival on site. Maintaining good pen drainage can be achieved by regular harrowing of the composting surfaces. The facility will conduct routine cleaning and harrowing to reduce standing water and incorporate wet manure. Reduce standing water Standing water can increase microbial digestion and odor producing by-products. Proper surface maintenance and surface harrowing will be conducted by the facility to reduce standing water. AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 27 The wastewater ponds will be dewatered within 15 days after a 25-year,24-hour storm event. Composting Proper composting turns manure into a nearly odorless, pathogen-free product that is valuable for soil conditioning. StroMo, LLC will maximize manure composting on the land area available for that purpose. Land application timing Typically air rises in the morning and sinks in the evening. StroMo, LLC will consider weather conditions and prevailing wing direction to minimize odors from land application of stormwater. Typically, land applications will be timed for early mornings. Pest Control Insects and Rodents Insects and rodents inhabit areas that I) have an adequate to good food supply and 2) foster habitat prime for breeding and living. Key practices StroMo, LLC will use to manage insects and rodents are to first eliminate possible habitat, and then reduce the available food supply. On-Site: The presence of flies will be minimized by frequently turning the windrow piles of manure waste as needed to avoid anaerobic conditions which tends to produce pockets of decayed wastes which, in turn, attracts flies. Additionally, the fly population will be controlled through the use of spray/mist equipment using EPA approved chemicals to treat the surface areas of the site where flies are observed to congregate. Off-Site: If flies are observed to be originating at the subject site and move offsite; fly bail traps will be placed along the perimeter of the site to minimize off-site migration. The facility will control flies by applying one or more of the following practices as needed: Regular manure removal and composting The management and frequencies outlined in this operations plan removes both food sources and habitat Reduce standing water Standing water is a primary breeding ground for insects Minimize fly habitat AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 28 Standing water, weeds and grass, manure stockpiles, etc., are all prime habitat for reproduction and protection. Reduce or eliminate these areas where practical. Manage weeds and grass Keep weeds and grassy areas to a minimum. These provide both protection and breeding areas. Minimize stockpiles or storage of manure Stockpiles of manure provide both breeding and protective habitat. Keep stockpile use to a minimum. Biological treatments Parasitic wasps are excellent biological fly control and are widely used. The wasps lay their eggs in fly larvae hindering fly reproduction. 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. Windblown Debris The migration of wind blown debris off-site will be minimized by the installation of mesh wire fencing along the perimeter of the proposed facility in the down wind direction of the prevailing winds. Any windblown debris that does escape the proposed facility will be recovered on a periodic basis. AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 29 Fire Protection Plan 14.4.2(L) The elements of a "Fire Protection Plan" were reviewed by the project engineer and Mrs. Wes Scott, Manager of the Platteville/Gilcrest Fire Protection District. The specific elements that Mr. Scott suggested should comprise the "Fire Protection Plan" are as follows: a) Access to the site should be clearly marked by signage posted at the main entrance. The signage should identify the Platteville/Gilcrest Fire Protection District as the designated "Fire Suppressor Provider" for the site, the business hours phone number for the district, as well as the ""911" emergency contact number. b) The site service road should provide easy access to all areas of the site being used for the composting process and allow for fire engine turnarounds within the site. Since no buildings are planned for construction at the site nor are any employees of the applicant required to be at the site on a permanent basis, no other special requirements of elements were required by Mr. Scott in preparation of the "Fire Protection Plan". Low Permeability Work Pad 14.4.3 The site will be graded and maintained to prevent ponding of stormwater and leachate to ensure groundwater protection. The site contains sufficient slopes of 3 to 9 percent to facilitate direction of stormwater drainage to the stormwater collection system. Manure and composted materials used at the site, once compacted, are known to create a "hard pan" of virtually impermeable surface materials approximately 6 to 10 inches thick. Given the type of soils and the degree of slope existent at the site, it is the opinion of the site engineer that the precautions and concerns articulated in this section of the regulations will minimize and adequately address protection of groundwater and surface water resources. Ground Water Monitoring 14.4.4 One up gradient and two down gradient groundwater monitoring wells will be installed around the site. The up gradient well will be located in the southeast portion of the property. The two down gradient wells will be located on the north and northwestern portions of the property respectively. The wells will be measured quarterly for groundwater elevations and calculation for groundwater flow direction. The wells will be sampled quarterly. Quarterly intensity will occur for the first year of operation. If no evidence of contamination is shown after year one, a written request will be submitted to the Colorado Department of Public Health and Environment and the Weld County Health Department to reduce groundwater monitoring frequency to yearly. AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 30 Management of the Compost Piles 14.5.4(A) (1) The density of the fecal coliform present in the compost shall be maintained at less than 1000 Most Probable Number per gram of total solids (dry weight basis); or (2) The density of Salmonella sp. Bacteria in the compost shall be maintained at less than three (3) Most Probable Number per four (4) grams of total solids (dry weight basis) at the time the compost is to be sold or otherwise distributed for use. NOTE: To comply with 14.4.5(A) of the regulations, a sample of the compost windrow subsequent to the blending of bulk materials with the manure will be taken in procedures described in the section entitled "SAMPLING/ANALYSIS PROCEDURES". During the compost process stage, the SOLVITA Maturity Index procedure will be used to monitor the maturity stage of each compost pile. Data generated by the SLOVITA protocol include CO2 rate and ammonia levels (NH3) in the compost mass and provides guidelines for manipulating these constituents to enhance the compost process. A copy of the SLOVITA testing guidelines are provided as an attachment to this document entitled "Guide to SLOVITA testing for compost maturity index? And is located in the "Appendix Section". Management of the Compost Piles 14.5.4(B) Compliance with 14.4.5(B) will be accomplished by maintaining the in-process compost pile at a temperature of 55 degrees Celsius (131 degrees Fahrenheit) or higher for 15 days or longer. During the period when the compost is maintained at 55 degrees Celsius or higher, there shall be a minimum of five (5) turnings of the windrow. Procedures for sampling and testing are previously described in the attached document entitled "SAMPLING/ANALYSIS PROCEDURES". Closure Plans 14.6 In the event that it becomes necessary to close the proposed composting facility, the site will be returned to its original condition. No permanent structures are planned for the site. All gates, fences and signs will be removed. The following closure tasks are expected: 7) Removal of Residual Materials from Facility: All raw composting materials, manures and residual materials (sawdust, crop residues, etc.) used in the composting process will be removed from the site and sent to another approved composting facility or permitted solid waste facility as necessary or incorporated into adjacent fields by plow cultivation in an agronomic manner according to Colorado State University, Cooperative Extension fertilization recommendations. 8) Removal of Compost Debris from Surface Soils in Windrow Areas: After the windrow area of the facility has been cleared of all composting material, the shallow surface area will be scalped to remove the compost "hard pan" layer that typically develops over extended periods of processing. This compost hard pan residue will be AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 31 removed from the site and also incorporated into adjacent fields by plow cultivation similar to paragraph 1 above. 9) Stormwater and Containment Structures: Any stormwater accumulation in the stormwater containment structure will be dewatered onto adjacent farmground in an agronomic manner according to Colorado State University, Cooperative Extension fertilization recommendations. Residual solids accumulations in the structure will be removed and land applied along with the surface soils from the composting areas as outlined in paragraph 2 above. The containment structure will be leveled and the ground returned to an original state prior to construction and operation. 10) Re-Contouring of Subject Site: All roads, ditches, berms, earthen diversion and containment structures will be graded back into the "cut area" from which it was generated to re-establish original surface contours. A laser leveling instrument will be used to tie in the re-contoured areas with original grades and contours. 11) Re-Seeding of Disturbed Surface Area: The disturbed surface area will be prepared by disking to produce a seedbed. A dry land grass pasture mix including a winter rye or oats cover crop seed will be drilled into the prepared seedbed. The newly seeded area will be fenced off from use for a time period adequate to allow the grass seed to germinate and become established. 12) Post Closure Ground Water Monitoring: Water samples from the proposed down gradient monitor well will be sampled on a quarterly basis and analyzed for the following: Nitrates Electra Conductivity (EC) Total Dissolved Solids Salts PH RCRA Metals Pottassium Phosphorus This monitoring program is planned for a period of five years. Evaluation of analytical results after year one will further define the need for continuing for all of years 2 through 5. 14.6.1 and 14.6.2 It is not anticipated that the site will experience some interim period of non-use. However, in the event that it becomes necessary to close the proposed composting facility including the discontinued receipt, processing and sale of materials for more than 180 days , or otherwise approved by the CDPH&E, the site will be returned to its original condition. The CDPH&E will be notified of closure activities and when closure is complete. Closure activities at the facility will not exceed 90 days without a prior written extensions granted by the CDPH&E. AgPro Environmental Services, LLC Your "Pro Ag"Environmental Professionals 32 14.6.3 and 14.6.4 Since no permanent structures will be constructed at the site, closure of the site at the conclusion of composting operations will consist of removing all compost and bulk materials from the site; disking of the surface areas used for composting, and re-seeding of the impacted site with a dry land pasture grass mix to be drilled in. Additionally, a straw-mulch will be lightly disked into the seedbed along with a separate seeding of the area with a cover crop of winter rye or oats to minimize soil erosion during the grass germination/maturation stage. Post Closure Care and Maintenance 14.7 A. Following closure of the facility, a notation will be placed on the deed notifying any potential purchaser that the property has been used as a composting facility. B. The post closure care and maintenance shall be for(5) five years and shall consist of: (1) The continued monitoring and sampling of groundwater or surface water.

OVERVIEW: The primary source of animal manure waste will be generated by MORWAI Dairies. Each load of manure received at the compost site will be logged into a traffic journal maintained at the compost site. The manure received will be either stockpiled in the receiving area or dumped directly into a compost row where bulking materials will be blended with the manure mass. There will be two stages of sampling/analysis conducted at the compost site. 11. Initial Sampling/Analysis Procedure: A. Sampling Procedure: Once the manure wastes are windrowed but prior to blending with bulking materials, random grab samples of the manure waste will be collected at designated linear intervals from one end of the row to the other end. Each grab sample should consist of +/- 1/2 pound of sample material and should be placed in one or more clean plastic 5 gallon pails. The grab samples will then be thoroughly blended in a large plastic tub. Once the sample mass has been successfully homogenized, a 1 pound composite sample will be collected and placed in a 1 gallon zip lock plastic bag; placed in a iced or refrigerated cooler; and delivered within 8 hours to a designated laboratory with a "chain of custody" document completed for each sample submitted (several samples may be entered on to a single document form. B. Analysis Procedure: The cornoosite sample will be submitted for laboratory analysis to determine the following constituent concentrations; - :iloisture (%) - Nitrates (ppm) - Nitrogen (°/0) - pH - EC (salts) - Organic Matter [(°/0) & (carbon:nitrogen ratio)] The test results for each sample submitted will entered into a "Lab Analysis" log book for future reference. NOTE: Based on the lab data generated during the initial sarnpiing/analysis stage, the raw manure waste will be mixed with bulking materials, water, and/or other nutrients to accelerate the bio-degradation process. After subsequent cyclical rotations (turnings) and other treatment of the windrowed manure mass has been completed, the second stage of sampling analysis will be accomplished. STROMO, LLC COMPOST FACILITY SAMPLING/ANALYSIS PROCEDURE ****ii**k********************fir****”••• Page 2 of 3 Ill. Final Sampling/Analysis Procedure: A. Sampling Frequency: in compliance with 14.5.2 of the CDPHE regulations, "(A) Finished compost will be sampled and tested once every 20,000 cubic yards of compost produced or annually, whichever is more frequent; and (B) Finished compost which has been sampled and tested, but to which additional feedstock is added prior to, or during distribution, shall be re-sampled and re-tested prior to commencing or continuing distribution". A. Sampling Procedure: ;n compliance with 14.5.3 of the CDPHE regulations, the following sampling procedure will be implemented to " assure valid and representative analytical results": Once the compost operations supervisor determines that an individual windrow of processed manure waste appears to have completed the bio-degradation cycle, random grab samples of the processed material will be collected at designated linear intervals from one end of the row to the other end. Each grab sample should consist of ±1- 1/2 pound of sample material and should be placed in one or more clean plastic 5 gallon pails. The grab samples will then be thoroughly blended in a large plastic tub. Once the sample mass has been successfully homogenized, a 1 pound composite sample will be collected and placed in a 1 gallon zip lock plastic bag; placed in a iced or refrigerated cooler; and delivered within 8 hours to a designated laboratory with a "chain of custody' document completed for each sample submitted several samples may be entered on a single document form.

It is based on measuring carbon-dioxide respiration and ammo- nia content simultaneously in the same test. Each test alone provides important clues to compost quality, and used together provide valuable information to judge the condition and safety of any composted product. I Compost Maturity is a term that has been used in a variety of ways. The Solvita Maturity Test ranks your compost on a 1-to-8 index scale of increasing maturity. Maturity means resistant to further decomposition and free of compounds such as ammonia and organic acids which can be toxic to plant growth. • The Solvita test can he used effectively for the following purposes: 1) Evaluating compost conditions in order to make improvements to the compost process; • 2)Establishing compost maturity for marketing reasons and to determine the best end-use prior to distribution and sales. Solvita Compost Testing: 3 Steps to Satisfactory Results There are three easy steps involved in using the Solvita test kit to evaluate compost. A- Obtain and prepare the sample. B- Perform the test by placing both Solana gel-paddles in the jar. Use enclosed Color Heys to find the appropriate color numbers. Use the simple computation table to determine !I your composts Maturity Index. C- Interpret the results. Once you (mow the maturity index, consider the process management and desired end use of your compost. Use the tables in the manual as well as the troubleshooting section to evaluate the process and determine the best use. TIPS ABOUT HANDLING THE SOLVITA KIT All Solvita lilts are carefully packaged at the factory to insure highest quality prior to ship- ping.The gel-paddles should be the "Control Color" when the foil pack is opened (see color chart). If the foil packs have been punctured or damaged, or the jar cracked in any way, then the test may not work properly. Store at room temperature and use within the indi- cated time period. Shelf-life is significantly extended by refrigerating the un-opened foil _packs. Do not allow to freeze.
