In their response they express concern that the facility may impact their ability to develop, produce, operate and maintain oil and gas wells on the land. Al Organics is aware of Patina's existing oil and gas wells located on the property we would be purchasing. We are also experienced with operating on other sites that have existing wells as well as the potential for future wells. As you are aware, the nature of our operations allows us great flexibility as to where we process and place material. We have not had conflict with the other oil companies who operate existing wells and have also drilled new wells on our sites. I have been in contact with Dave Siple at Patina and have expressed our intent to communicate and cooperate with them in operation of our site as it pertains to their leasehold rights.

Our use of catalyst will allow us to use less physical space, control odors more effectively (since windrows will not need to be aerated), and speed up our process. You requested additional information on the catalyst we intend to use at this site, as well as ow other sites. Over the past several months, AI and I larvest Quest International (the manufactute of the catalyst), have been accumulating data. The purpose of this correspondence is to present that data to you so that the department can approve the use of this material at Rattler Ridge, as well as our other sites. I have enclosed the following: • Correspondence to I larvest Quest from Colorado State University Environmental Health Services indicating that the isolated microorganisms contained in the catalyst are not considered "pathogenic to animals, plants, or humans." The letter also contains a detailed description of each of the isolates. • Correspondence to Harvest Quest from Colorado State University with general laboratory results containing organism counts. • A description of the Harvest Quest Catalyst provided by Harvest Quest. • Pathogen test results for biosolids compost produced by the Harvest Quest method at our Highway 66 facility. • Analytical data on compost produced by the Harvest Quest method. • Temperature data from composting operations using the Harvest Quest method reflecting data on a specific production unit.

At the time, I mentioned to Cindi that we would be taking it to Keenesburg instead, at least during the 30 day abatement plan period. It was our understanding that if we had our permit application submitted by the end of the initial 6 months, that we could continue operations at Keenesburg while the permit application was being processed. Today, when I reviewed the departments letter of October 8, 1999 regarding the pilot project, I noticed that it states"subsequent volumes to be allowed on the site, if any, following the 6 month period will be determined at that point". The situation at Highway 66 required us to take some material to the Keenesburg site, but the volume and duration has not been established. Before we divert the material back to the Highway 66 facility,I think feel it would be in prudent to consider another alternative that would benefit the County,Al, and the Grandview Estate residents next to the Highway 66 facility. We would propose that we continue to take the feedstock material to the Keenesburg facility over the next few months while our permit application is proceeding. This plan would be logical and beneficial for the following reasons: • It is our "unofficial"intent, that if our permit for Keenesburg is approved, that we will close down the Highway 66 facility and move the bulk of our operations to Keenesburg. [ say `unofficial"for the obvious reason that if it is not, we will need.to continue operations at the Highway 66 facility. • If we indeed move to Keenesburg, it would be logical and beneficial to not bring new feedstocks to Highway 66, but instead to continue processing those materials already at the Environmental Solutions • Economic Sense Eaton Facility 16350 WCR 76 • Eaton, Colorado 80615 • Tel 970-454-3492• 800-776-1644• Fax: 970-454-323r.

While we feel we can maintain a very low level of odor, it has been documented in several situations that tolerance levels decrease after initial complaints. Founded or unfounded, we would probably see more intense scnrtiny from the Grandview Estate residents. The best way to eliminate this, at least regarding our facility., would be to continue to reduce the volume on the site and not increase it by bringing new feedstocks on, at least for the short term. • We have shown that we can process a relatively large amount of material at Keenesburg on a fairly small amount of land space effectively without any adverse effects. Plus the Keenesburg site is much more remote which is an advantage. • The Keenesburg operation has been operating smoothly without incident. I met recently with the Town Council and they responded that they saw no conflict with our application • Increasing the volume of material at Keenesburg will provide additional beneficial information regarding the operation of this site if approved. We will be using our new Harvest Quest system that we would be using for larger volume composting in the future. The initial material we composted there was done in EcoPOD and standard windrow fashion, To facilitate continued operations at Keenesburg and not resuming new feedstocks going to Highway 66 we would not need to change any of the general conditions listed on the initial authorization with the exception of one. Since we have finished screened material on the site, plus the overs from the screening operation, plus additional material coming in we will need some additional area on which to process the new material. We feel we can handle all of the material needed during this period on a total of 15 acres (current 5 plus 10 more). Some of this area would be needed to store finished material and bulking agent. I feel we could need less, but that is my best guess at this time. Again, all other conditions of the pilot authorization would remain unchanged. We are also hopeful that we can have our application approved prior to January 1st. We also understand that allowing continued use of the Keenesburg site, and allowing us to expand the acreage on which we are operating there does not guarantee that Al Organics will receive approval for a Certificate of Designation and Use by Special Review or otherwise limit the exercise of the Board of County Commissioners discretion in considering the Certificate of Designation or Use by Special Review. I will also personally communicate with the Keenesburg Town Council to let them know that we would be expanding the 5 acre site to allow us to evaluate the impact of additional material being processed on the site.

While I had been in contact with Cindi, Roger, Julie Chester, and Julie Cotter numerous times during the project, I had not prepared a formal report after the second and fourth months. All of the material that we composted during the first 6 month phase of the pilot were in place by the end of March,which was basically the 2nd month After.that time we continued processing activities only. The six month report that I prepared has the total amount of material plus the activities we performed on it for the entire project. Since the project was not complex, and no problems were encountered, I was unsure if you wanted me to put together a separate two month report and an 4 month report since the six month report contains the information required. Please let me know if you would like separate reports for those months, or if the six month report, plus the verbal and in person information provided during those months time is sufficient.

The first used a ratio of 1.67 cy of bulking agent to 1 cy of brewery/biosolids waste. The second pod was filled using a ratio of 1.5 cy of bulking agent to 1 ay of brewery/biosolids waste. Bulking agent consisted of ground yardwaste, ground pallet waste, leaf mold, and some over sized material from previous composting. The bulking agents used were on an"as available"basis to simulate actual production situations. Feedstock and bulking agents were mixed and then loaded into the bag system with front end loaders. Sand was evident in the mix as a result of the loader mixing activity. Air was supplied by portable blowers powered by a portable generator. The blowers were attached to 2 perforated plastic air pipes that were placed in the bottom of the EcoPod bags, underneath the compost feedstock/bulking agent mix. The compost material was fed into the EcoPODS by a specialized machine designed by AgBag. Vents were installed near the top of the bags on both sides. The vents were spaced approximately 30 feet apart in an alternating pattern from side to side: A vent was thus present every 15 feet on one side of the bag or the other. The blower unit timers were set to turn on and off as desired. The initial setting was 4 minutes on and 10 minutes off. This pattern was changed during the process as determined necessary by the project manager. Temperature readings were taken during the process to monitor the composting process and to verify pathogen destruction based on EPA guidelines for in-vessel composting. After approximately 90 days of composting the bags were harvested by removing them. The composted material was left in place to cure and thy. The material was dry on the surface but fairly wet toward the center. There was no odor present, other than the earthy smell generally associated with finished compost_ The material was rather coarse in texture. Since on turner was used to aerate the material, this was not an unexpected condition. After 30 days in a curing stage, the materials were moved off the bottom plastic and placed in a windrow. The windrow was turned several times to further dry it and to loosen composted material from the uncomposted bulking agents. After turning the material was again piled to await screening.. The material was screened the end of August. The finished material screened from the EcoPODS was measured for volume. The north bag produced 135cy of finished compost The south bag produced 180 cy of finished compost. Finished compost was sampled and tested for standard compost nutrient test and pathogens as required by Colorado Department of Public Health and Environment and EPA 40 CFR 503.13 standards FROM : Al ORGANICS LOST ANTLERS PHONE NO. : 3P33849259 Sep. 14 200 E :4aPr Owing the composting period some light odors were evident around the bag vents, however, no odor was detected at the site boundaries, After a few days, the odor coining from the bag vents bad decreased and was non-offensive. Windrow Operations: Outing the remaining time of the initial pilot phase, standard windrows were formed using the same techniques used at other Al facilities. Biosolids cake and bullring agents were mixed using a front end loader and then placed in individual piles. Each pile represented 1 load of cake and required bulking agents- After the piles set for approximately 24 hours they were placed in standard windrows measuring approximately 16 feet wide and 6 feet tall. The windrows were aerated with a Frontier turner. Wmdrow temperatures were monitored dining the process and recorded After 150 days of processing the windrows were allowed to cure prior to being turned again to further dry them. They were then placed in larger stockpiles and screened. Screened compost was sampled as normal- Final volume of finished compost will not be determined until all material has been screened and shipped. Dining the windrow composting process odors:were minimal and not noticed off site. Truck trips were limited to a maximum of 25 trips per day, including truck trips facilitated by Coors Energy- - An application for a Use by Special Review and Certificate of Designation for the site was subuiittbd to the Weld County Planning Department on July 24, 2000 and is currently in process.

The site will be located on property we are under contract to purchase from Coors Energy Company of Golden Colorado. The property is located on Section 36, Township 3N, Range 64W. Our purchase contract is conditioned upon the receipt of a USR and CI) from Weld County. The following information corresponds to the Use by Special Review Questionnaire. 1 have also provided information as outlined in the State of Colorado's proposed Compost Facility Regulations (DRAFT) in support of the Certificate of Designation. Use by Special Review Questionnaire: I. Explain, in detail, the proposed use of the property. The site is to be used to stabilize and process all types of nonhazardous and nontoxic organic materials including, but not limited to those materials described in the State of Colorado Draft Compost Regulations types 1,2, and 3. This is not a disposal site. No wastes will be permanently disposed of at this site. Regulatory compliant materials will be processed by use of various composting methods or similar technologies. Current composting technologies include areated windrow, Page 1 of 9 Rattler Ridge USA Submittal Environmental Solutions • Economic Sense Eaton Facility 16350 WCR 76 Eaton, Colorado 80615 - Tel 970-454-3492 800-776-1644 Fa,::970-454-323.: Lost Antlers Facility 6569 Hwy, 93 ' Golden, Colorado 30403 ' Tel 303-384-9232 ' Fax:303-384-9259 aerated static pile, static pile, and various in-vessel systems. Soil's and soil related products will also be processed and or blended with soil amendments. The soil amendments and related soil products will then be marketed and or distributed. For a more detailed description of composting and the related activities, please see the operational plan and appendix information which is part of this submittal. 2. Explain, how this proposal is consistent with the intent of the Weld County Comprehensive Plan. The application is consistent with the Weld County Comprehensive Plan(WCCP) for several reasons: 1. The WCCP indicates an intent to encourage agricultural and farm uses within Weld County, along with those activities that promote products and services associated with, supplemental to, and dependent upon agriculture. This organic recycling facility will utilize waste generated by agriculture entities as both feed stock and bulking agent materials and process these materials into beneficial soil amendments. The finished products will be reused by both agriculture and. nonagricultural markets. Use of the facility and the products produced will benefit agriculture by providing an environmentally superior alternative to current disposal options as well as providing additional market's for materials generated by agriculture entities. 2. The site is also consistent with the county's goal of promoting positive, environmentally responsible alternatives for recycling waste as opposed to disposing of it. $ . The WCCP states that Weld County is a"complete farm and food system". This. organic recycling facility is an instrumental part of the complete system by producing a product ready for purchase. The products produced are beneficial for food production. 4. The WCCP promotes industries that purchase products grown or produced by agriculture. The composting facility may purchase materials from agriculture. But for the most part, it will offer an alternative that may reduce the costs of agriculture waste management. 5. The process can be categorized as a new and innovative method for using and promoting agriculture in Weld County. Page 2 of 9 Rattler Ridge USR Submittal 6. The composting operation is an exporter of goods and importer of income to Weld County. Al Organics' headquarters is located in Weld County and employees numerous Weld County residents. 7. The compost operation will capitalize on the quality of a natural resource ...organic waste. 8. Al Organics is a local rural based organization. Al has operated composting operations in a responsible manner for over 25 years. Included in their experience is composting operations and pilot programs that have processed virtually all of the potential products that would be handled at this facility. The site promotes the "necessary interdependent relationship between urban and rural areas", as put forth in the WCCP. 9. The site is directly dependent on the agricultural industry for both it's raw materials and markets for its finished products. 10. The site uses an appropriate location for a commercial or industrial use of agricultural land that at the same time benefits agriculture. It is consistent with the WCCP's goal of promoting the conversation of geologically suitable non-prime agricultural land to solid, liquid, and waste water disposal (processing) sites. 11. The site is consistent with the WCCP environmental Quality and Natural Resources guidelines. It does not promote erosion, reduced water quality, loss of productive farmland, and reduced fish and wildlife habitats. It assists in taking an active pail in conserving and preserving the environment by providing a responsible proven process for converting waste materials into useable soil amendments. 12. The organic recycling facility does not exceed the physical capacity of the land and water needed to accommodate the operation, nor does it have an adverse effect on water quality and quantity. 13. The organic recycling facility also provides Weld County with an alternative to landfill disposal of a large volume of organic waste (yardwaste, tree trimmings, garden waste, food waste, etc.). 3. Explain how this proposal is consistent with the intent of the Weld County Zoning Ordinance and the zone district in which it is located The applicants use's are both agriculturally and commercially based in nature and are therefore compatible with surrounding use zone districts. Page 3 of 9 Rattler Ridge USR Submittal 4. What type of uses surround the site? Explain how the proposed use is consistent and compatible with surrounding land uses. The site is boarded to the north by Coors Energy's Keenesburg Mine Site. Originally a coal mine, this site is now being used as a fly ash disposal site. The site is boarded to the east by vast expanses of open semiarid to arid range land and a natural gas processing and pumping facility. The site is boarded to the south by open semiarid to arid range land, used for cattle pasture and oil and gas production. The site is boarded to the east by Waste Management of Colorado's Buffalo Run Land Filll. The proposed use is consistent and compatible with surrounding land uses for the following reasons: 1. One of the main functions and benefits of facilities of this type is to divert com.postable organic waste materials from landfill disposal, thus saving valuable landfill space and instead recycling these materials for reuse. The facility mission is highly compatible with the recycling and diversion from traditional disposal site goals established by the State of Colorado and Weld County. The existence of an existing landfill within 2 miles of the site is thus not only consistent and compatible, but also very complimentary. 2. Many of the materials that can be processed at the facility have agricultural origins. The existence of agricultural operations within close proximity of the site is an advantage to both entities. The site will offer an environmentally superior alternative to traditional disposal options for agricultural waste materials, while the agricultural entities and related businesses offer a potential source of feedstock for the recycling facility and a market for the products it produces. 3. One of the markets for finished materials produced by the facility will be the mine/oil field reclamation market. The mine to the north of the facility will be a potential user of the finished compost produced. The material produced could also be.used for reclamation of oil production facilities, as well as land fill cover. The soil amendments produced, when added to existing soil, increase water holding capacity, help reduce erosion, and provide beneficial plant nutrients. Proper soil amendment i.s a vital part of reclamation. 4. A large portion of the land use surrounding the site is industrial and or commercial. Page 4 of 9 Rattler Ridge USR Submittal 5. Describe, in detail, the following: a. How many people will use this site? Site use for these types of facilities does not normally relate to the number of people who will use the site. While the site will have public access, site utilization is more easily equated with the number of trucks that will access the site. Similar sites that we operate average daily truck traffic of between 35 - 50 visits per day, based on a 365 day year. We would anticipate that in the first 5 years of operation an average of 50 trucks per day will be the upper limit of the site. After the first 5 years operation of the site, we would anticipate that the average number of trucks accessing the facility would be in the 75 to 100 trips per day (based on a 365 day year). b. How many employees are proposed to be employed at this site? During the first 5 years of operation of the facility 3-10 full time employees will be utilized at the site. Additional employee's required for project specific operations such as grinding, screening, additional loader work, etc., will add to this number for short periods of time. c. What are the hours of operation? Normal hours of operation for public access will be from 7:00 AM to 5:30 PM, Monday though Saturday. Commercial access will be from 5:00 AM to 11:30 PM, seven days per week. Production or emergency requirements may at times require extended hours of operation. d. What type and how many structures will be erected (built) on this site? Initially, the site will utilize only a office trailer at the main gate. However, during the life of th facility, it is likely that the following structures will be placed into use. • Office building (1) • Bagging or special project facility (1) up to 20,000 square feet • Maintenance shop and equipment storage (1 - 4) of up to 5,000 square feet each • Sorting sheds (1 - 4) of up to 5,000 square feet each • Warehousing (1)up to 60,000 square feet • Truck scale • Page 5 of 9 Rattler Ridge USR Submittal e. What type and how many animals, if any, will be on this site? The only animals that would be on the site would be livestock which would graze on non used portions of the site. A security guard dog may also be kept at the site. f. What kind (type, size, weight) of vehicles will access this site and how often? • The normal types of vehicles that will access the site are trucks and semi trucks with trailers. Weights will be within legal limits for these types of vehicles. Some passenger car and pickup traffic will also access the site. • We would anticipate that in the first 5 years of operation an average of 50 trucks per day will be the upper limit of the site. However, after the first 5 years of the site,we would anticipate that average number of trucks accessing the facility would be in the 75 to 100 trips per day range (based on a 365 day year). g. Who will provide fire protection to the site? The applicant will petition Keenesburg Fire Protection District for service to the site. They are currently providing service for Coors Energy's facility h. What is the water source on the property? (Existing and proposed) The only existing water source on the property is a livestock well which will be modified to provide for non-potable water use. An application for a new well may also be considered. Potable water will be brought to the site. i. What is the sewage disposal system on the property(Existing and proposed) There is no existing sewage disposal system on the property. Initially, the operator will employ use of potable toilet facilities. At a future date, it is anticipated that a septic tank with leach field will be installed for sewage disposal. J. If storage or warehousing is proposed, what type of items will be stored? Warehousing of organic soil amendments, packaging materials and supplies, normal maintenance items such as oils and grease for equipment, and general equipment and tool storage is anticipated. Page 6 of 9 Rattler Ridge USR Submittal 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 site is located on an isolated and privately accessed rural location. There is no formal landscaping plan anticipated for the site. 7. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Per state of Colorado and Weld County regulations for facilities of this type, a reclamation plan along with suitable financial assurance instrument is included as part the requirements for issuance of the Certificate of Designation. Said financial assurance will be in place prior to operation of the site. 8. Explain haw the storm water drainage will be handled on the site. The site topography and geology are such that no storm water will accumulate or leave the site. A discussion of storm water retention is included as part of the Certificate of Designation information required for this facility. 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. The site is large enough to allow for initial operations on approximately 200 acres. Operations will expand to other areas of the facility as required. It will take approximately 60 days or less to construct the initial operational site and locate the modular office facility. Additional construction(such as maintenance buildings, etc.), will be built as needed during the operation of the facility. Proper building permits for permanent structures will be obtained prior to construction activities associated with those facilities. Initial construction of the site would begin within 30 days of issuance of USR and Certificate of Designation. 10. Explain where storage andior stockpile of wastes will occur on the site. Temporary storage of wastes will be done on secluded locations. Appropriate organic wastes will be recycled though the composting process. Trash will be stored in approved containers and land filled as needed. Storage of liquids or solid organic wastes will be necessary. In most cases, the liquid received will be applied directly to bulking agents or composting materials. If liquid Page 7of9 Rattler Ridge USR Submittal storage is needed, it will be facilitated in portable above ground storage tanks or other approved containment. Wood and other solid materials will be stored in stockpiles at various locations around the site. The application form, copy of title insurance, road access information, affidavit of interest: owners - surface estate, names of owners of property within 500 feet, affidavit of interest owners - minerals and subsurface estate, and mineral owners and lessees of mineral interests are attached As you are aware, Al Organics has been actively involved with composting operations within Weld County and the rocky mountain region for over 25 years. The Rattler Ridge Facility will be operated with the same professional standards we apply to our sites in Platteville, Golden„ Loveland, and Cheyenne Wyoming. Sincere Robert S.

Estimated quantities of feedstocks and bulking agents The site has approximately 200 acres of production site. Each acre of production is capable of processing from 7,500 cubic yards per acre per year for standard windrow composting to as much as 30,000 cubic yards per acre per year using aerated static pile composting. These volumes are based on the beginning volume of the composting unit. An average bulk density of compost mixture is around 1,200 to 1,400 pounds per cubic yard,. The total capacity of the site could be expressed as being able to receive between 1,500,000 cubic yards per year(or 975,000 wet tons), and 6,000,000 cubic yards per year (3,900,000 wet tons). These totals-would include both feedstocks and bulking agents. Additionally, the site could handle up to 35,000,000 gallons per year of liquid's. Estimated quantities of in process materials. At any one time the maximum amount of in-process material would be equivalent to approximately 1/3 of the annual inflow quantity. This would calculate to approximately 500,000 cubic yards for windrow composting to 1,980,000 cubic yards for aerated static pile. Estimated quantities of finished product on site. Estimated maximum volume of screened, finished material , ready for shipment on the site at any one time would be 100,000 cubic yards of compost and 35,000 cubic yards of soil product A detailed description of the composting operation specifically defining all procedures and activities: Composting Process Description Composting of organic materials has been a widely accepted practice for centuries. In the past few decades, in has become more refined and accepted as a method of dealing with all types of Page 2 of 15 Rattler Ridge D&O Information organic waste materials such as animal manure's, municipal solid waste, biosolids, food waste, yard wastes, and water treatment plant residuals A typical compost mixture will have a carbon to nitrogen ratio of between 30 - 40:1, and a moisture content of around 40-50%. Less moisture causes a retardation of biological activity, and greater moisture may clog pore spaces between particles, thus restricting oxygen transfer Composting is generally an aerobic process which allows microorganisms indigenous to the material being composted to degrade or decompose (digest) the organic material and convert it into heat, carbon dioxide, and water. Successful composting occurs in the thermophilic temperature range. The elevated temperatures are obtained by biological activity in the composting material. No input of heat or energy is required. The process develops temperatures that eradicate weed seeds and pathogens. Bulking agents are often blended with feedstocks to provide porosity for oxygen flow and to act as a carbon or nitrogen source for the bacteria. The final compost produced contains humus, stabilized organic mater, micro and macro nutrients, and beneficial soil bacteria. It is generally moist, dark in color, has no objectionable odor, and free of pathogens and weed seeds. Introduction of compost to soil increases the water holding capacity, improves structure and texture, increases porosity, and provides soil bacteria critical for healthy, disease resistant plant growth. While compost is classified as a soil amendment, it contains significant levels of organic nitrogen, phosphorus, and potash. Organic nitrogen will not leach or volatilize, and thus will not increase nitrate levels in soils and water supplies. The following overview is intended to provide an overall concept of how the facility will operate. Changes in operational procedures will occur based on experience and actual conditions encountered once the facility is in full scale operation. Composting Operations Feedstocks and bulking agents will arrive at the facility by truck or other means of transportation. After an initial inspection of the material, receipt of the feedstocks and bilking agents will be documented. Documentation will include generator and transporter information, classification of the material, and volume information. If required, samples of the materials may be taken at this time. The generator and or transporter will sign the receiving ticket which will include a statement similar to the following: "The generator/shipper hereby acknowledges that the material described above contains no hazardous or toxic material. AI Organics reserves the right to reject partial or full shipment. The generator/shipper assumes all responsibility and cost for removal and disposal of any non-approved or rejected materials delivered to Al Organics facilities. ' Page 3 of 15 Rattler Ridge D&O Information After documentation is completed, the materials will be off loaded at designated areas for storage and or processing. Production activities will consist of mixing or blending of feedstocks and bulking agents, transportation to processing sites, and formation of, or placement in appropriate processing units (windrows, in-vessel systems, static piles, etc.). Mixing and blending will take place either on a designated mixing pad, or on the final processing area depending on the nature of the feedstocks and or bulking agents being blended. The mixing pad will be used for liquid or semi liquid feedstock materials (biosolids, WTP residuals, etc.). More stable, dryer materials (dry biosolicls, manure's, bedding, yardwaste, etc.), may be either mixed on the pad., or on the processing site. Once prepared on the mixing pad, the mixture will be transported to a production processing area within the site boundaries. After placement on a production processing area, the composting process will begin. Al will utilize the best available technology in determining which composting procedure to use. Currently, composting technologies fall in one of several types of processes: Aerated Windrow: Aerated windrow composting is currently the most common type of composting procedure. In this procedure, feedstocks and bulking agents (if required) are blended to produce the pre-compost mixture. The compost mixture is placed in long piles called windrows. The windrows can be all types of sizes, but generally are approximately 12 - 18 feet wide, and 6 - 9 feet tall. These windrows are normally sized to accommodate the type of equipment that will be used to aerate them. As an example, if a windrow turner is used, they will usually not exceed the 12 - 18 foot by 6 - 9 foot dimension. However, if front end loaders are used to aerate them, the windrows can be 20 - 30 feet wide, and 10 -15 feet tall, depending on the size of the loader used to build them. Once formed the bacteria and fungi present in the windrows will begin the composting process. The bacteria will cause the pile temperatures to increase. Tile temperatures normally will reach the 140-150 degree range. Temperatures are controlled via aeration and by moisture balance. The major byproducts of the decomposition process produced by the bacteria and fungi present in the pile are carbon dioxide, water vapor, and heat. During the composting period, the windrows will be aerated using the specialized equipment or loaders. The aeration process is done to introduce additional oxygen to the pile, release excess moisture, reduce particle size, and to condition the material in the windrow. Windrows will be aerated approximately 5 - 20 times before the process is complete. Page 4 of 15 Rattler Ridge D&O Information Static Pile: Static pile technology is similar to aerated windrow technology in that large piles of predetermined mixtures of materials are constructed. The difference is that the piles are allowed to compost without excessive aeration events (turning). Temperature in the piles will again elevate as they do in the aerated windrow technique. Pile structure is very important if static pile process is used. Pile structure will determine the air flow and subsequent availability of oxygen to the bacteria, moisture balance, and overall efficiency of the composting process. Often a catalyst, accelerator, enzyme, or cultured bacteria is added to the static pile (they can also be added to the aerated windrow). These materials are added to increase the biological population in the pile and thus decrease the time it takes to complete the process. They are also used to target specific constituent's of the material (sulfur, hydrocarbons, etc.). Bio-filter caps (ground wood, etc.), can be placed on top of the static piles to help control odors if necessary. Aerated Static Pile: Aerated static pile composting is very similar to static pile with the exception that pipes with blowers attached to them are placed under or in the compost piles to provide additional oxygen to the bacteria. These pipes can either be sacrificial, or permanent and reusable. The fans are used to pump air through the pipes into the piles when oxygen levels within the piles need to be increased. The air flow also helps remove excess moisture. Bio-filter caps(ground wood, etc.), can be placed on top of the static piles to help control odors if necessary. In-Vessel In-vessel composting is similar to aerated static pile composting with the exception that the process is done within a closed vessel, bag, or building of some typ€' This process may be done either aerobically or anaerobically, and is generally very expensive. In-vessel composting can also utilize accelerator's, enzymes, and bacteria to effect the process. Vern icomposting Often referred to as worm composting, this produces earthworm castings through earthworm activity associated with their consumption of organic materials. Page 5of15 Rat Ridge D&O Information A biological catalyst or accelerator (enzymes, cultivated composting bacteria, etc.), may also be utilized in the various processes to decrease composting time, increase nutrient values of finished products, control odors, or to target specific constituents of the material being composted. Composting, sampling, and testing procedures will be carried out in a manner that will comply with requirements necessary to be certified for Unrestricted Use and Distribution as defined in Colorado State Biosolids Regulation, #64 (5 CCR 1002-64). After 1:he compost process is completed, the compost material will either be placed in a curing pile, screened, or shipped. Material placed in a curing pile will be screened and or shipped at a later date. • Uncornposted organic materials that come off the screening unit (overs) will be reintroduced into the composting process, or further processed for marketing and distribution. Non-compostable overs will be disposed of in a proper manner. The site will also produce other landscape and or horticultural materials, such as top soil, prepared top soil, mulch, potting soil, etc. Top soil and prepared top soil will utilize soil, compost, and water treatment plant residuals as primary ingredients. Water treatment plant residuals will also be utilized as basic feedstocks in the composting process itself. All steps in the production of finished compost and other landscape materials will be documented. Regulated materials (biosolids, water treatment plant residuals, etc.), will be tested by generator with analytical information kept on site for reference. Analytical information will also be made available to the governing body as required. Finished materials will be stockpiled as required and then shipped to various markets via truck or other appropriate transportation means. Compost Standards and Sampling Standards: Compost that is sold or distributed for off-site use, shall meet the standards set forth in Table of the Draft Composting Regulations. Depending on the feedstock and or bulking agent materials used, the Department, after consultation with the governing body, may require additional analysis. Compost that exceeds the levels specified in Table 1 must be: • Reintroduced into the composting process • Disposed of'at a permitted solid waste disposal facility, • Otherwise used in a manner approved by the Department and governing body. Page 6 of 15 Rattler Ridge D&O Information Sampling Procedure's Finished compost shall be sampled and tested once every 20,000 cubic yards of compost produced, or annually, whichever is more frequent 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. Bulking Agents Analysis of bulking agent materials (wood, straw, etc.), will be done as required by production quality control manager or assigned operator personnel. Feedstock Materials Biosolids • Contract Clients Site files will contain biosolids analytical information as required by Colorado State Department of Public Health and Environment. Analytical information will be updated annually. • Occasional or One Time Clients: Biosolids analysis or certification of Class B status for occasional or one time clients will be obtained prior to receipt and processing of the biosolids. Water Treatment Plant Residuals • Contract Clients — Site files will contain WTP residual tests as required by Colorado Department of Public Health and Environment. Analytical information will be by generator facility. Analytical information will be updated quarterly or as defined by CDPH&E. • Occasional or One Time Clients: Residual analysis' as required by CDPH&E will be obtained and on file prior to receipt of material. Page 7 of 15 Rattler Ridge 1*O Information Other Feedstock Materials Any feedstock that would normally require some type of regulatory reporting to CDPH&E may require sampling. Prior to receipt of new materials, the operator will contact the governing body, descriptio the new feedstock and determine what, if any analytical information is required. From time to time, animal manure's, food waste, wood waste, grass, leaves, and other non-regulated feedstock materials will be processed. Analysis of these and similar materials will be up to the operators discretion. Biosolids Compost Pathogen Testing-Salmonella/Fecal/Ascaria Lumbricoides&Enterovirus The total number of combination tests per facility per year will be in compliance with the minimum number of pathogen tests required for each facility based on the number of dry tons of biosolids compost and material containing biosolids compost produced at the facility in a calendar year, as reported on the facility annual report. The CDPH&E Biosolids Regulations will dictate the number required. All pathogen testing required will meet one of the protocols approved and defined in Colorado Department of Public Health and Environment Water Quality Control Commission, Biosolids Regulation # 64 and EPA 40 CFR 503.13 publications. • Aerated Windrows Alternative 1 - Compost being produced using the aerated windrows technique will be sampled when they are near or have completed certification for time, temperature, and aeration requirements. A random grab sample will be taken from the windrow. A minimum of one grab sample per 250 cubic yards of in process material. The individual grab samples will be combined in a mixing bucket and mixed thoroughly. The mixed material will be screened over a 1/2" screen. A grab sample of the screened material will be pulled and placed in a sealed bag (minimum of pound sample). The bag will be labeled with the date, facility location, and windrow number and sent to an EPA certified lab for testing. Alternative 2 - A random grab sample from windrows will be taken as in alternative 1 The sample will be screened though a '/2 " screen. A sample will be pulled from the screened material (minimum of pound sample), labeled with the windrow numbers contained in the sample, and placed in a refrigerator. The sample will be cold pack shipped to a certified laboratory and tested for Ascaria Lumbricoides and Enterovirus as required to be certified as a Class A, Grade I Biosolids materials suitable for unrestricted use and distribution. Page 8 of 15 Rattler Ridge D&O Information • Static Pile A random grab sample from the finished static pile material will be pulled and screened through a 1 " screen. A sample from the screened material (minimum of 1h pound sample) will be taken, labeled with the pile number, refrigerated and then sent to and EPA certified lab and tested for Ascaria lumbricoides and Enterovirus to be certified as Class A, Grade I Biosolids material suitable for unrestricted use and distribution. • Aerated Static Pile and In-Vessel Alternative 1 - Compost being produced using aerated static pile or in-vessel technique will be sampled when they are near or have completed certification for time and temperature requirements. A random grab sample will be taken from the material. A minimum of one grab sample per 250 cubic yards of in process material. The individual grab samples will be combined in a mixing bucket and mixed thoroughly. The mixed material will be screened over a 1/2" screen. A grab sample of the screened material will be pulled and placed in a sealed bag (minimum of/2 pound sample). The bag will be labeled with the date, facility location, and windrow number and sent to an EPA certified lab for testing. Alternative 2 - A random grab sample from windrows will be taken as in alternative I. The sample will be screened though a 1/2 " screen. A sample will be pulled from the screened material (minimum of 1/2 pound sample), labeled with the windrow numbers contained in the sample, and placed in a refrigerator. The sample will be cold pack shipped to a certified laboratory and tested for Ascaria Lumbricoides and Enterovirus as required to be certified as a Class A, Grade I Biosolids materials suitable for unrestricted use and distribution. Biosolids Stock Pile (BATCH) Samples Windrows, static piles, aerated static piles, and in-vessel compost will be screened by batch. Random grab samples (at least 3 per week)will be taken from the batch as it is being screened. A new batch will be designated at least once per month. At the completion of each batch a screened material sample will be pulled and sent to a EPA certified lab for pathogen testing. The batch sample will also be sent to a EPA certified laboratory for nutrient and metal analysis per CDPH&E requirements. Non-Biosolids Compost and Soil Products Grab samples of non-biosolids compost and soil products will be pulled periodically. Samples will be accumulated until the end of the month. A grab sample of the month's production will be taken from the composite and sent to a certified soils lab for analysis. A standard compost or soils analysis will be performed. Page 9 of 15 Rattler Ridge D&O Information Copies of all analysis information will be keep on file at the site. Windrows, static piles, aerated static piles, or in-vessel materials that fail to meet the minimum standard for compliance will remain in the composting process and be re-tested at a later date. Records will be maintained to verify that biosolids being produced meets or exceeds the requirements of the then current document required for certification of Class A, Grade 1[ biosolids for Unrestricted Use and Distribution. Description of an adequate system of barriers, fencing, and or other site controls to prevent unauthorized site access: The site is located at the end of a 2.25 mile long private road. The site itself is surrounded by barbed wire fencing. Additionally the entrance road to the site itself(off of the private road) will be gated. Signage to ensure adequate traffic control and a telephone number to contact in case of emergency. A facility information sign will be placed at the entrance to the site. The sign will list the operator, emergency numbers, and hours of operation at a minimum. Additionally, on site signage will be used to direct and traffic, and to address site rules and policies. A description of surface water control systems designed, and constructed and maintained to : 1). Prevent flow onto the facility during peak discharge from a 25 year, 24 hour storm event, 2). Control and collect the on-site run-off water volume resulting from a 25 year, 24 hour storm event, 3). Contain and manage leachate which is generated when precipitation comes in contact with on-site materials, 4). All leachate collection structures shall be constructed of compacted or in-situ earthen material or other low permeability materials to achieve a hydraulic conductivity of less than or equal to 1 * 10-5 cm/sec. , 5). Storm water/leachate collection structures shall be dewatered within 15 days of a storm event so that the full runoff storage capacity is restored. Detailed hydrological and geological evaluation of the site. Two detailed hydrological and geological evaluations of this area are included with submittal information. The evaluation done for the Keenesburg Mine site includes the property on which the compost site will be located. The evaluation done for the Waste Management Land Fill was done on property located directly to the west and southwest of the compost site. Page 10 or 15 Rattler Ridge D&O Information These reports, both individually and collectively provide detailed information regarding Hydrologic properties of the uppermost aquifer, Information regarding the existing quality of ground water beneath the proposed facility, The types and regional thickness of consolidated bedrock material, Geologic hazards such as slope stability, faulting, folding, rockfall, landslides, subsidence or erosion potential. Hydrological and Geological information indicate 5 main features regarding the site: 1. The site is covered with a thick layer of eloian sands. 2. There is little ground water beneath the site, and what little water that exists is of poor quality. 3. There are no domestic wells in the immediate area. Wells that are present are used for livestock, irrigation, and or commercial activities. 4. The bedrock and shale located beneath the site separate it from any aquifers. Aquifers are located several hundred feet deep. 5. There is no evidence that surface water moves onto or off the site. Surface water migration is very limited. Based on the hydrological and geological information for the facility and surrounding area, the site will be prepared and monitored as follows: • It would not be logical to construct water retention structures to divert or contain water that will not exist, therefore the basic topography of the site will be left as is. This will also help minimize the potential for wind erosion. • The operator will take background soil samples of the site prior to composting. Periodic soil tests will be taken in areas of active composting to assist in evaluation of the site. • All regulated liquids and semi-liquid materials or volatile materials will be premixed on mixing pads the meet the regulatory requirement. • The mixing pad will be designed to retain moisture from a 24 hour, 25 year event. An evaluation of potential impacts to existing surface water and ground water quality, including but not limited to: Surface Water: There is not existing surface water structures or impoundment's on or near the site. Since no surface migration of water is possible, and in considering the lack of any potable ground water under the site, no impoundment of surface water control features would be constructed on the site. To construct berm's or dam's to hold water which would not be present would be futile. Additionally, disturbance of surface materials to construct these impoundment structures would expose the area to potential wind erosion problems. Page 11 of 15 Rattler Ridge I)&O Information The operator will be processing only nonhazardous and or nontoxic materials. In lieu of surface water containment structures, the operator will conduct annual soil sampling tests to determine the makeup of the surface materials. The types, frequency, and depth of soil sampling will be negotiated between the operator and the governing body. Ground Water: Little to no ground water exists under the site. However, the operator will monitor both existing ground water monitoring wells located on the site, plus any additional monitoring wells established on the site. The number and type of additional wells, if any, will be negotiated by the operator and the governing body. Other Environmental Controls: Airborne Materials: The windrows and or piles, will be kept moist and will crust over within a short period after being formed. Fugitive dust will be controlled via watering. Stockpiles of bulking agents subject to movement by wind will be watered to control wind movement. Odor: The composting process will produce some odors. However, with proper operation, odors can be controlled. Wood or finished compost can be used as a bio-filter if necessary. Odors generated when windrows or piles are turned or moved can be present. The operator will manage these activities to coincide with wind direction, time of day, and or other criteria to midigate any impact from odors. Vectors:. Frequent aeration of windrows, crusting of piles, or containment with in-vessel systems will discourage vermin infestation. Heat and activity also discourages harrowing vermin. Experience has shown that composting actually eliminates fly larvae. Flood plain information including evidence that the proposed site is not located within a 1.00 year flood plain. • Public water supply information including the location of all water supply wells, springs, and surface water intakes within one mile of the proposed facility boundary.

Identification of all lakes, rivers, streams, springs, or bogs, on site or within %2 mile of the proposed facility boundary. There are no lakes, rivers, streams, springs, or bogs on site or within '/2 mile of the facility boundary. Fire protection plan shall be provided in compliance with local fire codes.. Fire protection will be arranged with the Keenesburg Fire Protection district. Plans for interim and final closure of the composting facility as defined in Subsection 14.6 Contingency plans developed, maintained current, and available at all times, which outline the corrective or remedial procedures to be taken in the event of: Page 13 of 15 Rattler Ridge D&O Information • The delivery of unapproved waste: As material is received at the site, it will be classified and documented. The receiving ticket signed by the generator or shipper will contain the following statement: "The generator/shipper hereby acknowledges that the material described above contains to hazardous nor toxic material. Al Organics reserves the right to reject partial or full shipment. The generator/shipped assumes all responsibility and cost for removal and disposal of any non-approved or rejected materials delivered to Al Organics facilities." Unproved or rejected materials received at the site will be removed and taken to a permitted disposal facility. • Contamination of surface water or ground water Contamination of surface or ground water issues will be dealt with on a specific occurrence basis. The operator will notify the governing body of any contamination of surface or ground water that is identified. • The occurrence of nuisance conditions either on site or off site. Nuisance conditions that may occur on or off site will be dealt with on a specific occurrence basis. Remedies or procedure's necessary to remedy a specific condition will be arrived at through discussion with the governing body. • Interim Closure Plans In the event that interim closure becomes necessary due to conditions as defined in section 14.6.2 of the Draft Composting Regulations, the operator will take the following minimum steps: Control nuisance conditions by continuing to process materiaTto a point of stabilization and or contain material is such a manner as to control nuisance conditions. Secure all containment fencing and gates and manage the site until such time as the operation is placed back into full operation. If after a period of 180 days following a notice from the governing body that interim closure status is to be implemented, the operator has not reinitiated normal operations. then the operator will begin implementation of final closure procedure's. Page 14 of 15 Rattler Ridge D&O Information • Final Closure Plans Upon notification from the governing body that final closure plans are to be implemented, the operator will negotiate and implement a closure plan suitable to the governing body and implement the specific plan within 30 days of receipt of notice from the governing body. Page 15 of 15 Rattler Ridge D&O Information Appendix B Weld County Road Access Information Sheet Access to the site is via WCR 18 east to WCR 59 north. WCR 59 ends approximately 2.25 miles south of the site. From this point to the site a private road that accesses Waste Management of Colorado's Buffalo Rim Land Fill and Coors Energy's Keenesburg Mine will also be used to access Al Organics' Rattler Ridge facility. There is currently an agreement in place between Waste Management of Colorado,Coors Energy, and Weld County regarding maintenance and use of WCR 18 and WCR 59 from the intersection located at Interstate 76 east and north to the end of WCR 59. This existing referenced agreement was made at the time the land fill was permitted and assumed that the land fill would be in operation. As of this date, the land fill has not opened for operation. As a part of issuance of the USR and CD for this site, Al Organics would propose that the current stake holders (Waste Management, Coors Energy, Al Organics, and Weld County) negotiate and enter into a new agreement regarding maintenance of WCR 18 and WCR 59. It would be our proposal that such an agreement would allow for current maintenance requirements on the road to be completed or documented, and that future maintenance requirements would be based on percentage of use basis.

Although, the general slope of the plain is to the east and southeast, the local topography is dominated by the South Platte River and its tributaries, which have created various landforms including flood plains, terraces, and uplands. Generally speaking, the topography in the north ?ortion of Weld County is gently undulating to rolling. South of the South Platte River valley the land surface is rolling to hummocky. The South Platte River valley itself is gen :rally planar to gently undulating. Elevations in the county range from a low of approximately J 4,400 feet above sea level at the point of egress of the Pawnee Creek to highs of approximately 6,200 feet above sea level in the northwest portion of the county. The topography of the Keenesburg site is characterized by rolling ridges, consistink primarily of eolian sand, stabilized by sage brush and prairie grass vegetation ThE l ground slopes gently to the northeast toward Ennis Draw. Ennis Draw is at best at J ephemeral stream; based on careful observation in the area, no evidence of surface floe has ever been found. Ennis Draw leads to the northwest, ultimately joining the Be Elder Creek drainage system, which is in turn tributary to the South Platte River. 2.2 CLIMATE Climatic conditions at the Keenesburg facility are generally mild and semi-ann. According to mapping presented in Hansen et al. (1978), the mean annual precipitation is in the range of 12 to 14 inches and the mean annual evaporation is greater than TO 1 2-1 Keenesburg Ash Disposal Site Revision 1.0 Ground-Water Monitoring Plan Doty & Associate:_ September 25, 1998 inches. Also from this source, the mean annual relative humidity is between 50 and 55 percent and winds are generally to the north. — 2.3 GEOLOGY The Keenesburg site is located in the Denver structural basin, a major geologic feature extending from Colorado into western Nebraska, Kansas and eastern Wyoming (Robson 1987). The Denver Basin is a north-south trending asymmetrical downwarp invciving a: much as 13,000 feet of sedimentary rock (Costa and Bilodeau, 1982). According ti mapping presented in Costa and Bilodeau(1982),the thickness of the sedimentary sectio beneath the site is probably on the order of 10,000 feet. _ The stratigraphic section at the site consists of the Precambrian crystalline basement roc overlain by a thick section of pre-Cretaceous and Cretaceous sedimentary ants. T units beneath the upper-Cretaceous Pierre Shale are probably somewhat thicker than tl:e 3,135 feet observed on the western flank of the basin (Weimer, 1973). The Pierre She e itself is on the order of 8,000 feet thick(Weimer, 1973) and consists of fossiliferous mar,:: e — shale,silt, and clayey sandstone,containing numerous calcareous concretions (McWhorti-r and Ortiz, 1978). For purposes of this plan, the Pierre Shale is the lowest geologic ur..t of interest, because it is considered the base of the water yielding units in the Deny• r Basin (Robson, 1987). The units above the Pierre Shale are as follows. o Fox Hills Sandstone. The Fox Hills Sandstone is composed of calcareous man re sandstone intermixed with dark-gray to black sandy shale and some massive wh to sandstone (McWhorter to range from 60 feet (Weimer, 1973) to 300 feet thick (Colton an is dAnderson, 1977). o Laramie Formation. The Laramie Formation which directly overlies the Fox H lls Sandstone is the uppermost bedrock unit at the site (younger consolida1 ed materials have been removed by erosion). The Laramie Formation consists of yellow-brown and gray to blue-gray soft carbonaceous shale and clay-shale interbedded with sand and shaley sand (McWhorter and Ortiz, 1978). It contains 2-2 Keenesburg Ash Disposal Site Revision 1.0 Ground-Water Monitoring Plan September 25, 1998 Doty & Associates cress-bedded gray to buff sandstone, which is slightly to well-cemented, and contains coal in the lower portion (McWhorter and Ortiz, 1978). Although individual Laramie coal beds are often lenticular,laterally discontinuous and vary considerably in thickness, seven thicker and more continuous seams have been identified in the lower Laramie (e.g., Amuedo and Ivey, 1975). The coal seam mined at the Keenesburg site is the No. 7 seam (Coors Energy, 1996), which is stratigraphically the highest and youngest seam in the Laramie coal group. The No. 7 seam is the only coal seam that appears to be present in the lower Laramie at the site and averages seven feet thick (Coors Energy, 1996). The depth to the No. 7 seam averages about 120 feet (McWhorter and Ortiz, 1978). _ oQuaternary Deposits. The Laramie Formation is covered with deposits of alluvium and dune sand (McWhorter and Ortiz, 1978). The alluvial materials consist of silty, clayey. fine to coarse grained sands with occasional ravel particles ranging _ from 1/8 to 1.5 inch diameter (Coors Energy, 1996). The occurrence of the alluvial materials is restricted to the Ennis Draw paleo-channel in the eastern third of Section 25 (Coors Energy, 1996). The dune sand (also known as blow sand) covers the alluvial materials or directly _ overlies the Laramie where the alluvium is absent (McWhorter and Ortiz, :978) The dune sand is essentially of uniform thickness, averaging about 20 to 30 feet (McWhorter and Ortiz, 1978). According to testing at an adjacent property, the sand is very fine to fine grained with little or no clay (IC, 1992). Consistent with the location of the site relative to the center of the Denver Basin, the base of the Fox Hills dips gently to the southwest at about 1 degree (Robson et al., 1981). The base of the Laramie probably has an equivalent dip. The top of the Laramie is an erosional surface which appears to slope to the northeast toward Ennis Draw. The location of the alluvium associated with Ennis Draw is shown on Figure 2 and generalized stratigraphic column for the site is presented as Figure 3. In addition, cross-section showing the relationship of the eolian sand and alluvial materials (as wel as other details) is presented as Figure 4. 2.4 HYDROGEOLOGIC CONDITIONS • The significant aquifers of the Denver Basin include the alluvial and terrace deposit; along the major rivers and streams, the Dawson Aquifer, the Denver Aquifer, th Arapahoe Aquifer, and the Laramie-Fox Hills Aquifer. The permeable units beneath th 4 1 2-3 Keenesburg Ash Disposal Site Revision 1.0 Ground-Water Monitoring Plan September 25, 1998 Doty & Associates Laramie-Fox Hills have not been developed for water supply because they are very deep (below the relatively impermeable and thick Pierre Shale) and other shallower supplies are available. Because the site is located on the northern flank of the basin, the younger (stratigraphically higher) aquifers have been removed by erosion; only the Laramie-Fox Hills is present beneath the site (Robson et al., 1981). The Laramie-Fox Hills Aquifer consists of sandstones at the base of the Laramie Formation and the upper portior of the underlying Fox Hills Sandstone. The aquifers of the Denver Basin are largely recharged by infiltration into outcrops (Robson, 1987). In the center of the basin, downward movement of water from overlying units is also an important recharge mechanism (Robson, 1987). However, the vertical movement of water from overlying units is probably an insignificant recharge s echanisn: _ for the Laramie-Fox Hills because of the thick shales in the upper Laramie Formation (Robson, 1987, page 23). Robson (1983) estimates the following regional parameters for the Laramie-Fox Hills Aquifer: o average hydraulic conductivity is 0.05 feet per day, which is equivalent to 1.8x10" centimeters per second lcm/s); o transmissivity is approximately 8 square feet per day; and, o storage coefficient is 3 x In the northern portion of the basin, flow in the Laramie-Fox Hills is away from th« outcrop along the mountain front toward the South Platte River (Robson et al , 1981 There is also considerable use of water from the Laramie-Fox Hills is the general area which has created a potentiometric trough trending to the northeast, located us'; west 1' the site (Robson et al., 1981). Based on 1978 potentiometric conditions shown ir. Robso.t • et al. (1981), ground water beneath the site in the Laramie-Fox Hills is flowing to th northeast under a gradient of approximately 0.002. II 2-4 3 Keenesburg Ash Disposal Site Revision 1 0 Ground-Water Monitoring Plan Doty & Associates September 25, 1998 --- As stated earlier, the vertical movement of water from overlying units is probabl) an insignificant recharge mechanism for the Laramie-Fox Hills. Therefore, the Laramie-Fox Hills is not expected to be impacted by operations at the site. The hydrogeologic units that have potential to be important are as follows. 1. Soils. Both the eolian sand and the Ennis Draw alluvial materials are relatively permeable. IC (1992) reports an hydraulic conductivity of 1x10-3 cm/s for the eolian sand, although the material is dry at their site and at the Keenesburg facility. It appears that both the hydraulic conductivity contrast between the eolian sand and the underlying Laramie Formation and the rate of recharge are sufficiently small that ground water is not perched in the sand. The Ennis Draw Alluvium is saturated and produces water to several wells and windmills in the general area. McWhorter and Ortiz (1978) report a conductivity cf 1x10-0 cm/s for a single slug test in this material (Table 2-1). Two of the wells in the monitoring system are completed in this material (FPW and DH-96). Data are too limited to define the direction of flow in this material; however, it can be expected to have a component of flow parallel to the axis of the spatial distribution of the material (see Figure 2). 2. Overburden. The silty claystones and sandstones above the coal in the upper portion of the Laramie Formation are known locally as the overburden and have been found to be water-beating. Ground water occurs in these materials under both confined and unconfined conditions (McWhorter and Ortiz, 1.978) and flow is generally to the northeast (Figure 5) McWhorter and Ortiz (1978) were of the opinion that the ground water in the overburden was in good connection with, and discharging to the Ennis Draw alluvium. Based on hydraulic testing described in McWhorter and Ortiz (1978), the overburden has a geometric mean hydraulic conductivity of 3x1O5 cm/s (Table 2-1 , although this is likely an over-estimate of the true value because of wellbore storage effect,. 3. Coal. Ground water also occurs in the coal under confined conditions and probably had little or no communication with the overlying water in the overburden (McWhorter and Ortiz, 1978). Ground-water flow in the coal prior to its removal was mostly to the east (Figure 6). Based on testing described in McWhorter and Ortiz (1978), the coal has a geometric mean hydraulic conductivity of 9x10" cm/s (Table 2-1) although this too is likely an over-estimate of the true value because of wellbore storage effects. 4. Clayey Backfill. The final unit in the hydrogeologic regime at the site is the mixed overburden (known locally as spoil) replaced in the mining pit. Given the degree of comminution and mixing produced by the excavation and replacement process, it is likely that the hydraulic conductivity of the replaced overburden is low and may be similar to that of the undisturbed overburden (an opinion expressed by 2-5 Keenesburg Ash Disposal Site Revision 1.C Ground-Water Monitoring Plan September 25. 1998 _ Doty & Associates McWhorter and Ortiz, 1978). No data are available to quantify the as-placed hydraulic conductivity. Thus, the uppermost aquifer for the ash and mine waste rock disposal cells consists of the Clayey Backfill, Overburden and Ennis Draw Alluvium, all of which form a single interconnected system. The clayey backfill (spoil) and overburden portion of the system is probably relatively impermeable, having an hydraulic conductivity on the order cf 3x10 cm/s, or lower. The alluvium, on the other hand, is probably relatively permeable, having a conductivity of 1x10-0 cm/s, or higher. The entire, interconnected system is generally under unconfined conditions. Prior to raining, flow in the overburden was generally to the northeast to its point of discharge into the alluvium (Figure 5) and flow in the alluvium was also believed to be to the northeast, although there is probably also a northwest component following :he alignment of the draw. Based on measurements made over the past five years, water levels have generally been steady at all points monitored, with the exception of SMW-2 (Figure 7). The SMW-2 data demonstrate a fairly linear trend of rising water levels of about 2 feet per year and even the most recent measurement indicates that the ws.ter level at this location is approximately 26 feet lower than the pre-mining level. A current potentiometric map (Figure 8) has been prepared for the site by superimposing the December 1997 data on the 1978 potentiometric map (Figure 5). The current data for three of the wells (DH-122, FPW and DH-96) agree well with the 1978 depiction and the older potentiometric surface mapping was not changed in these areas. However, considerable modification was required to fit the SMW-2 data into the older mapping (only a slight modification was required for the AMW-1 data). The resulting potentiometric surface map (Figure 8) implies that ground-water flow at the site is dominated by recharge to the replaced overburden (i.e., all flow is inward). The conclusion that recovery of the ground-water system following mining is still occurring is somewhat surprising in light of the opinion expressed in McWhorter and Ortiz (1978) that full recovery would occur in a period on the order of three years after 2-6 ;Keenesburg Ash Disposal Site Revision 1.0 Ground-Water Monitoring Plan Doty & Associates September 25, 1998 cessation of mining. Given that mining ceased in 1987, McWhorter and Ortiz (1978) predict full recovery by about 1990. However, it is clear that the SMW-2 water level is considerably lower than the pre-mining prediction for its location. The SMW-2 reference elevation is reasonable for its location and the measurements are about half the depth of the well; therefore, the data are reasonable and are accepted. In addition, it is clear that the water level is gradually rising in the well; this is a long-term trend that is unlikely to result from measurement error and is therefore accepted. Finally, it is clear that the water level in SMW-2 is lower than the water level in all surrounding wells; therefore, there must be at least a component of flow from all other well locations toward SMW-2. Given all of the foregoing, it is concluded that recovery of the ground-water system is will occurring. In order to test the feasibility of this conclusion, simple closed-form caLc,lations were performed to predict the current recovery rate in the former pit area. There are two sources of recharge to the system:infiltration .and flow from undisturbed materials on '.he pit perimeter. Infiltration recharge is probably on the order of 10 percent of the precipitation, or roughly 1.2 inches of infiltration annually. Assuming that 20 percent of the voids must be filled before the replaced overburden :s resaturated, the 1.2 inches of infiltration result in a recovery of about 0.5 feet per year. The recharge produced. by flow from undisturbed materials can be roughly estimated using the expression for steady radial flow to a well. Assuming that the pit has a radius of 2,000 feet and the radius of influence is 4,000 feet, an inflow corresponding to another 0.5 feet of recovery is predicted (this calculation further assumes that three-quarters of the pit is in undisturbed overburden and the other quarter is in Ennis Draw Alluvium and that 20 percent of the voids in the replaced bacicfill must be filled to achieve resaturation). Thus, an overall recovery rate of about 1 foot per year is estimated for the current conditions. Given the uncertainties in the analysis, this is considered excellent agreement vdth the observed recovery rate of about 2 feet per year and provides additional support to the conclusion that the ground-water system is still recovering. 2-7 1 Keenesburg Ash Disposal Site Revision 1.0 Ground-Water Monitoring Plan September 25, 1998 Doty & Associates 2.5 HISTORICAL GROUND-WATER DATA SUMMARY The quality of the ground-water in the uppermost aquifer (the interconnected Clayey Backfill, Overburden and Ennis Draw Alluvium system) is and always has been of relatively poor quality. Most of the wells produce samples with total dissolved solids (TDS) concentrations in the 500 to 1,500 milligrams per liter (mg/1) range. The samples from SMW-2, completed in the clayey backfill, exhibit TDS concentrations of approximately 7,000 mg/l. The waters are mostly dominated by sulfate among the anions, and by calcium and sodium among the cations. The trace metals are generally non- detectable, except manganese which is present at relatively low concentrations (generally 1 less than 0.5 mg/1). The water quality database is presented in Appendix B, together with temporal plots of some key parameters. The temporal plots presented in Appendix B indicate fairly strong trends toward increasing concentrations (particularly TDS sulfate, chloride, calcium, and magnesium) in the samples from wells DH-122 and FPW. The AIVIW-1 well samples may exhibit a mild trend toward increasing concentrations of some of these parameters. The samples from wells DH-96 and SMW-2 do not exhibit temporal trends. DH-96 is completed in the Ennis Draw Alluvium and is outside the radius of influence of drawdowns to the fanner pit. S1VIW-2 is completed in clayey backfill and exhibits much more saline characteristics than the other wells, perhaps due to intimate contact of the resaturating ground-water with clay surfaces freshly exposed by the comminution involved in the excavation and replacement of the overburden. The processes responsible for the higher salinity in the SMW-2 samples and the increasing concentrations in samples from wells DH-122, FPW and AMW-1 are not fully l understood. However, they are clearly not impacts from the disposal operation. Because Jground-water flow is currently dominated by resaturation of the clayey backl5ll, the wells exhibiting increasing concentrations (DH-122, FPW and AMW-1) are all in areas tha cannot be impacted by the disposal cells. The increasing concentrations (especially in DH-122 and FPW) appear to be natural processes or are the result of impacts from off-sit( 1 2-8 Keenesburg Ash Disposal Site Revision 1.0 Ground-Water Monitoring Plan Doty & Assoc September 25, 1998 activities of others. The concentrations in the SMW-2 samples, although higher that those in the samples from the other wells, are too steady to result from a release from the disposal cells. Therefore, the high concentrations in these samples appear to result from a natural process, such as dissolution or mobilization of materials from the clayey bac:kfll 2.6 SURFACE WATER HYDROLOGY There are no perennial streams or ponds within the site boundaries. In fact, there is no evidence of surface runoff on-site or in the general vicinity of the site. Essentially all precipitation apparently infiltrates the highly permeable mantle of sand and enters .he uppermost aquifer (as defined above). No water-formed erosional features such as rills and gullies are evident. This is also true of Ennis Draw which is a broad, fiat-bottomed depression with no observable channel or gully. 2.7 LOCAL WATER USE Based on discussions in McVYrhorter and Ortiz (1978), most of the residents in the s•.te vicinity depend on privately owned wells for domestic and livestock watering uses. McWhorter and Ortiz i 1978) report that of the 24 nearby wells, 7 (all located in close proximity of the site) are completed in the Ennis Draw alluvium; the remaining 17 wells are apparently completed in the Laramie-Fox Hills Aquifer. These conditions are not likely to have changed since the preparation of McWhorter and Ortiz (1978) because of limited development in the area. There is essentially no use of surface water it the general site vicinity. 2.9 Keenesburg Ash Disposal Site Revision 1.(i Ground-Water Monitoring Plan Doty 8; Associates September 25, 1998 Table 2-1.

All nine of the isolates are considered normal environmental flora that are commonly isolated from compost, silage, suil and water samples. None of the isolates are consider pathogenic to animals, plants, or humans. A detailed description of each of the isolates follows. Acti nomycetes: Streptomyces thermovulgaris: A common eurythermal thermophile with excellent growth at 60'C, good growth at 40-50'C, and slight growth with sparse formation of aerial hyphae at 28'C. Reportedly grows better under anaerobic conditions at the higher temperatures. Isolated primarily from fresh or rotted manures. Streptomyces thermonitrlfIcans: Named for Its thermophilic nature and virorous nitrate reducing ability. Exhibits no anti microbial activity. It is an obligate thermophile, growing at 37-50'C, with optimum at 45-5(1C. There is no growth at 27'C or below. Thernroactinomyces (sacchari 71 The Thermoactinomyces are commonly isolated f-om soh, compost, manure, self heated hay, and sugar cane rompost. Optimal growth 55-60'C with a range of 35-65t Aerobic bacteria: Bacillus (sterothermophilus ?1: Spores occur in soil of all climatic zones and have been found in deep ocean core sediments. Being obligate thermophiles, they rapidly lose viability at room temperature. They can grow anaerobically and strongly reduce nitrates. Racillus (coagulans 7): Relative rare in soils but common in silage where fermentable sugars and acid concentrations are high. Grows in the 45-55`C range and a pH range of 4.5 to 5.5. Lactobacillus sp.: Commonly isolated from soil, compost, silage, and manure. Some species of lactobacillus are used as starter cultures for cheese. yoghurt, and fermented milks. Growth range is 2S-S0'C with optimum at 35-45'. Streptococcus thermophilus or foecalis Common in dairy wastes, manure, and plant material where rio feces have been found Thrives under acidic conditions and higher temperatures Opitmum growth range is 40-45"C Fungal Isolates: Absidia(corymbifera 71.

Arop ENVIRONNIEN'l'AI, TI?('IINOLOGIF.S • Accelerated Composting Process The I larvest Quest process has been successfully used, over the past 10 years, throughout Europe and South East Asia. Many solutions to long- standing environmental problems have been developed through pilot projects and full scale production facilities, producing organic fertilizers and disposing of problematic waste streams. Harvest Quest has developed an organic "catalyst" that initiates a composting process, which is revolutionary and contrary to known science. Once the windrows are formed, the outer edges become active first, and the microbes generate temperatures in excess of 150 degrees Fahrenheit. 'the microbes then work their way towards the center of the piles generating similar temperatures as they move. This has the effect of reversing normal composting physics and provides many benefits. Transference of the microbes from the outside of the windrows towards the center, ensures total pasteurization and mineralization during composting, eliminates odors and kills primary and secondary pathogens. It also, in some cases, eliminates the need for mechanical turning, therefore saving on production costs. The biggest most amazing benefit however, is the sheer speed of the composting process. Conventional composting can take between 4 to 9 months and therefore requires large areas of land to carry out the task. With the Harvest Quest process however, the timeframe can be reduced to as little as 28 days. Also with conventional composting the resulting end products are, in most cases, very low in nutrients, especially nitrogen, which is lost to the air in the form of ammonia gas. With the I larvest Quest process, because of the lack of mechanical turning and the tact that outer edges of the windrows become active first, any ammonia gas produced in the interior is nitrified by • the microbes in the outer edges before it reaches the air. Therefore, virtually all of the. nutrients are retained, resulting in an end product with a much higher commercial value. Product Data - Organic Catalyst The catalyst is a completely natural organic material that contains a vigorous consortium of bacteria and some fungi. It resembles a compost in appearance and is non-toxic and inflammable. The bacteria used within the catalyst are actinomycetes. Actinomycetes are commonly found in soils and lorm thread-like branched filaments; they are responsible for the distinctive scent of freshly exposed moist soil. The strains used by I larvest Quest in the catalyst are thermophilic species, as they need to be able to function at temperatures exceeding pasteurization. In the compost pile they play an important role in degrading complex organics such as cellulose, lignin, chitin and proteins. Their enzymes enable them to breakdown tough debris such as woody sterns and bark. Actinomycetes arc also becoming increasingly important in field of bioremediation and are capable of filtering and degrading a large variety of human-made pollutants in the soil and groundwater so that they are no longer toxic. Certain bioremediation techniques using the catalyst have therefbre been developed by I larvest Quest. The list of materials they can detoxify includes herbicides, heavy metals, and petroleum products. The actinomycetes and fungal strains used by Harvest Quest are classified as saprophytes, which means they arc only' able to degrade dead cells. They obtain energy from breaking down organic matter from dead plant or animal matter and therefore constitute no risk to human or animal health. They are harmless to plants, aquatic life and beneficial soil organisms. The addition of certain Iungal strains in the catalyst is important for the composting process. They are responsible for the decomposition of many complex plant polymers and breakdown tough debris, enabling the bacteria to continue the decomposition process in a fast and effective manner. They spread and grow vigorously by producing many cells and filaments, and they • attack organic residues that are too dry, acidic, or low in nitrogen for bacterial decomposition. The catalyst can be manufactured anywhere in the world using local strains. Therefore, all the strains of bacteria and fungi, used here within the catalyst, originate from within the U.S. and are naturally occurring and are not altered or modified in any way. The uniqueness of the catalyst therefore, allows it to be safely used in any location.
