Gathman Case Number: MUSR14-0030 Applicant: Heartland Biogas, LLC Authorized Tim Naylor—AGPROfessionals Agent: Request: A Minor Amendment to a Site Specific Development Plan and Use by Special Review Permit No. USR-1704 (solid waste disposal site and facility including Class I composting, an animal waste recycling or processing facility (an anaerobic digester-based renewable energy plant (gas)) along with a concrete batch plant to be used for construction of the facility) for the addition of a Digester Process System and a 70-foot flare in the A (Agricultural) Zone District Legal Being a part of the SE4 of Section 25, T4N, Ri351/1/of the 6th P.M., Weld County, CO Description: Location: West of and adjacent to County Road 49; north of and adjacent to County Road 40 Size of Parcel: +/- 115.91 acres Parcel No.105525400011 THE DEPARTMENT OF PLANNING SERVICES' DIRECTOR APPROVES THIS APPLICATION FOR THE FOLLOWING REASONS: 1. The proposed change(s) will be compatible with existing and allowed uses in the surrounding area and be in harmony with the neighborhood. The proposed digester processing system will not increase traffic to the existing Heartland Renewable Energy Plant. The application indicates that traffic to the site will be reduced by approximately 10%. Only four (4) employees (2 employees per shift will be associated with this use. Per the application materials, the flare will be used only periodically (during maintenance or when the facility or when the valve for sale of gas is shut). Additionally, the flare allows 100% of the gases produced by Heartland to be combusted should an emergency situation occur. 2. The proposed change(s) is consistent with the County Comprehensive Plan pursuant to Chapter 22 of the Weld County Code. Section 22-2-20 B.3 A.Policy 2.3. states: "Encourage development of agriculture and agriculturally related businesses and industries in underdeveloped areas where existing resources can support a higher level of economic activity. Agricultural businesses and industries include those related to ranching, confined animal production, farming, greenhouse industries, landscape production and agri-tainment or agri-tourism uses." The proposed digester system will reduce traffic to the site and enhance the ability of the Heartland facility to process agricultural and other wastes. 3. The proposed change(s) will not result in a substantial adverse impact on the other property in the vicinity of the subject property. MUSR14-0030 Page 3 of 12 The proposed digester and flare are located approximately 1/3-1/2 mile to the east and northwest of the nearest single family residences. No letters or phone calls have been received from surrounding property owners in regards to this application. The site is already developed and the digester will reduce traffic to the site and the flare will only be operated when necessary. 4. The recommendations of the referral agencies have been considered. The attached Development Standards and Conditions of Approval address the requirements of the referral agencies. 5. Not deemed to be a major change. A Pre-Application (PRE12-0179) meeting was held on August 7, 2014. In discussions with the Weld County Department of Planning Services, the Weld County Public Department of Public Health and Environment, the Weld County Department of Public Works, and the Weld County Building Department it was determined that the proposed modifications are consistent with the existing permit and minor in nature. 6. Must be consistent with the original development standards. Many of the original development standards are still applicable and will be listed on the MUSR map. Some of the development standards have been updated to match existing policies and standards that have been revised since USR-1704 was originally approved in July of 2010. This approval is based, in part, upon a review of the application materials submitted by the applicant, other relevant information regarding the request, and responses from referral entities. The Department of Planning Services' staff recommendation for approval is conditional upon the following: 1. Prior to recording the plat: A.

WELD COUNTY'S RIGHT TO FARM: Weld County is one of the most productive agricultural counties in the United States, typically ranking in the top ten counties in the country in total market value of agricultural products sold. The rural areas of Weld County may be open and spacious, but they are intensively used for agriculture. Persons moving into a rural area must recognize and accept there are drawbacks, including conflicts with long-standing agricultural practices and a lower level of services than in town. Along with the drawbacks come the incentives which attract urban dwellers to relocate to rural areas: open views, spaciousness, wildlife, lack of city noise and congestion, and the rural atmosphere and way of life. Without neighboring farms, those features which attract urban dwellers to rural Weld County would quickly be gone forever. MUSR14-0030 Page 11 of 12 Agricultural users of the land should not be expected to change their long-established agricultural practices to accommodate the intrusions of urban users into a rural area. Well-run agricultural activities will generate off-site impacts, including noise from tractors and equipment; slow-moving farm vehicles on rural roads; dust from animal pens, field work, harvest and gravel roads; odor from animal confinement, silage and manure; smoke from ditch burning; flies and mosquitoes; hunting and trapping activities; shooting sports, legal hazing of nuisance wildlife; and the use of pesticides and fertilizers in the fields, including the use of aerial spraying. It is common practice for agricultural producers to utilize an accumulation of agricultural machinery and supplies to assist in their agricultural operations. A concentration of miscellaneous agricultural materials often produces a visual disparity between rural and urban areas of the County. Section 35-3.5- 102, C.R.S., provides that an agricultural operation shall not be found to be a public or private nuisance if the agricultural operation alleged to be a nuisance employs methods or practices that are commonly or reasonably associated with agricultural production. Water has been, and continues to be, the lifeline for the agricultural community. It is unrealistic to assume that ditches and reservoirs may simply be moved "out of the way" of residential development. When moving to the County, property owners and residents must realize they cannot take water from irrigation ditches, lakes, or other structures, unless they have an adjudicated right to the water. Weld County covers a land area of approximately four thousand (4,000) square miles in size (twice the size of the State of Delaware) with more than three thousand seven hundred (3,700) miles of state and County roads outside of municipalities. The sheer magnitude of the area to be served stretches available resources. Law enforcement is based on responses to complaints more than on patrols of the County, and the distances which must be traveled may delay all emergency responses, including law enforcement, ambulance, and fire. Fire protection is usually provided by volunteers who must leave their jobs and families to respond to emergencies. County gravel roads, no matter how often they are bladed, will not provide the same kind of surface expected from a paved road. Snow removal priorities mean that roads from subdivisions to arterials may not be cleared for several days after a major snowstorm. Services in rural areas, in many cases, will not be equivalent to municipal services. Rural dwellers must, by necessity, be more self-sufficient than urban dwellers. People are exposed to different hazards in the County than in an urban or suburban setting. Farm equipment and oil field equipment, ponds and irrigation ditches, electrical power for pumps and center pivot operations, high speed traffic, sand burs, puncture vines, territorial farm dogs and livestock, and open burning present real threats. Controlling children's activities is important, not only for their safety, but also for the protection of the farmer's livelihood. MUSR14-0034 Page 12 of 12 iQ4Ao.

The Board of County Commissioners met with Public Works and Planning staff on Monday morning and unanimously directed staff to work with the applicant on the following items: 1. The applicant proposed access point, which is approximately 1,400 feet north of CR 40 on CR 49 will be closed. The closure will occur after the new access at CR 40 is completed. 2. The permanent access to the applicant's facility on CR 49 will be at CR 40. 3. The applicant will be responsible for the construction of the road from their facility to the intersection of CR 49 at CR 40.The estimated distance is 2,000 feet.The estimated cost to construct a new roadway equivalent to applicants existing roadway, is $128,380. 4. The applicant submitted a cost estimate of $864,000 for the turn lane improvements to be constructed with asphalt pavement. The $128,380 will be subtracted from the $864,000 estimate. Thus, the applicant will submit to Weld County$735,630 for intersection improvements at CR 40 and 49 as the permanent access point. 5. Applicant and Public Works staff will cooperate on creating a revised improvements agreement which will be submitted to the Board of County Commissioners for approval within 30 days. Please respond to this email, so we know you have received it. We look forward to resolving the above items and bringing the Heartland project to a close. If you have any additional questions please feel free to contact Elizabeth Relford or myself. Janet Lundquist Traffic Engineer Weld County Public Works Dept. P.O.

There have also been discussions about installing the needed improvements to the intersection of CR 40 and abandoning the approved access on CR 49 and moving the facility access to CR 40 west of CR 49. HBG is agreeable to the concept of the relocation of the approved access and the required road improvements to CR 40 at an equitable exchange comparable to the construction costs of the turn lanes at CR 49. HBG requests forty five (45) days to evaluate and review the construction requirements, easements and limitations of both CR 40 and the internal access road and all associated logistics and cost thereof. HBG will request additional bids for the construction of the original turn lanes to reflect current market conditions as well as costs for the internal road relocation and CR 40 improvements. In order to fully evaluate the engineering requirements of the intersection of CR 40 and the expansion of CR 40, HBG request the county's intersection and road design plans be provided to HBG's design engineer. HBG will not release the authorization to proceed with the above described review and evaluation until HBG is provided a response of basic agreement with this proposal by Weld County. In summary, the only remaining item would be agreement on exact costs and not access points and relocation. Please fl iree'to contact me if you have any questions with regards to the HBG proposal. r Sinncerely;' /; ------. ,Tom aren z'/' CEO Cc: Ralph Daley, EDF ENGINEERING, PLANNING, CONSULTING & REAL ESTATE 3050 671h Avenue• Suite 200•Greeley,CO 80634 970.535.9318/office• 970.535.9854/fax• wu w atzpros.conn From: Janet Lundquist To: Chris Gathman; Elizabeth Relford Cc: Michelle Martin Subject: RE: Heartland MUSR comments(DRAFT) - Let me know if you need anything added Date: Tuesday,February 24,2015 11:04:16 AM Hi Chris, I think you have us covered with the note about getting an approved access permit and the improvements agreement.To date we have not heard anything further from AgPro regarding the access on CR 40 or the current IA, but they told us they needed 45 days to respond.

Explain, in detail, the proposed amendment to the property. Heartland Biogas, LLC (HBG) is requesting a minor amendment to USR-1704 to allow the addition of the Digester Process System (DPS) at the HBG site. The DPS will receive source separated food waste material as described in the Colorado Department of Public Health and Environment Approved Engineered Design and Operations Plan (EDOP), Waste Characterization Plan and be processed for the HBG facility digester. Locating the DPS at the HBG site will reduce truck traffic by approximately 10%by eliminating the added water if emulsified off site. Trucks containing food waste from the northeast Colorado vicinity will enter the facility, off load at the DPS receiving area, and leave. These incoming Substrates will be documented,particle sized reduced, hydrated, and blended as needed prior to transferring to HBG facility digester system. The DPS EDOP will be included in the HBG EDOP as an addendum and submitted to the Colorado Department of Public Health and Environment, Solid Waste Division for review and approval as part of the Use by Special Review (USR)process. The CDPHE solid waste department has reviewed the preliminary facility design and provided a letter stating that the amendment to the approved EDOP is not considered a substantial change to the provisions of the Certificate of Designation, the letter is included in the USR application. The HGB project has a flare that will be used if the PSA system is undergoing maintenance or if the valve for the sale of gas is shut so no gas will go to the common carrier pipeline. In the worst case, raw biogas will be sent to the flare for destruction. These flares provide for the combustion of 100%of the biogas being produced by the HGB facility should an emergency situation occur (such as a fault in the interstate gas pipeline that precludes injection of HGB's product gas). 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 (Comprehensive Plan). Sec. 22-2-20. Agriculture Goals and Policies A. 5. A.Policy 1.5. Support and entice agriculturally related businesses and processing facilities. The proposed use is consistent with the Weld County Comprehensive Plan through the encouragement of agriculture and agriculturally related businesses. The DPS is to be operated as part of a permitted agricultural business related animal waste material Minor Amendment to USR Al Organics/Heartland Biogas,LLC Page 2 of 3 recycling. The DPS will provide substrate as part of the input into the digester for the Heartland Biogas facility. 3. What types of uses surround the site?

Therefore, a storm water quality pond is not required for this development as the improved area lies within the existing Heartland Biogas drainage area. The grading has been designed to allow for runoff consistent with the approved Heartland Biogas drainage and, other than the spill containment areas, act in accordance with the Heartland Biogas drainage plan. The A-1 Organic proposed area is almost entirely located within the previously described low perm pad location on the Heartland plan, so the area will be significantly more permeable than the low perm pad. Per the items described above, there should not be additional drainage submittals required for the introduction of the DPS site to the Heartland drainage area. r)f_ / d ,(O% 11 1 �� e° \J F•� ze.o��e �N "✓ Chad TeVelde Civil Engineer ENGINEERING, PLANNING, CONSULTING & REAL ESTATE 3050 67th Avenue• Suite 200 •Greeley.

INTRODUCTION Heartland Renewable Energy, LLC (Heartland) is proposing to design, permit, build and operate an anaerobic digester-based renewable energy plant for the primary purpose of producing pipeline grade natural gas from cattle manure and other organic waste streams. This traffic impact study updates the April 10, 2009 traffic impact study for this project. It reflects an access change, provides anticipated construction traffic, and addresses County comments of the earlier study. Heartland is located along the west side of Weld County Road 49 (CR 49) at Weld County Road 40 (CR 40). Access will be provided by a driveway to CR 49 north of CR 40. A vicinity map is presented in Figure 1. Key work tasks undertaken as part of this effort are described below, U Obtain current traffic and roadway data in the immediate area of the site. • Determine site generated traffic and distribute this traffic to the nearby street system. O Estimate traffic for future roadway conditions. • Evaluate traffic operations with the proposed facilities fully operational un- der future conditions. O Identify areas of potential deficiencies. 9 Recommend measures to mitigate the impact of site generated traffic and other deficiencies as appropriate.

CURRENT CONDITIONS A). Current Road Network CR 49 is a major north — south roadway extending from 1-76 to U.S. 34. It is a two lane roadway with a posted speed limit of 65 MPH. The site is located in the north- west corner of the CR 49 — CR 40 (extended) intersection. CR 40 to the east of CR 49 is an unpaved two lane roadway which is under stop sign control at CR 49. Cur- rent roadway geometry is shown on Figure 2. B). Current Traffic Conditions Traffic counts were undertaken in conjunction with this study. Traffic was counted at the CR 49 - CR 40 intersection between the hours of 7:00 AM and 9:00 AM and between the hours of 4:00 PM and 6:00 PM framing the typical highway morning and afternoon peak hours. The high continuous peak hour within the two hour count times represents the morning and afternoon peak hours. Traffic during these peak hours is shown on Figure 3 with count sheets provided in Appendix A. The County has indi- cated that the traffic counts seem low, but further discussion determined that they are within normal fluctuations. Capacity analyses were conducted at the CR 49 — CR 40 intersection using current traffic demands and the existing roadway geometry. Current operating levels of service are shown below.

As shown, acceptable operations are currently being experienced. Capacity worksheets are provided in Appendix B. C). Surrounding Land Uses The site is currently vacant and is surrounded by rural and agricultural land uses. III. SITE ASSUMPTIONS Heartland Renewable Energy, LLC is proposing to design, permit, build and operate an anaerobic digester-based renewable energy plant for the primary purpose of producing pipeline grade natural gas from cattle manure and other organic waste streams. This renewable energy gas production plant will use proprietary anaerobic digester technology that converts organic waste (cattle manure, food wastes, livestock processing, etc.) into a methane-rich gas which will be scrubbed of impurities and then injected into a natural gas pipeline. The plant will use technology in which an organic feed stock is placed in an air tight vessel where naturally occurring microbes digest the feedstock and create methane and carbon dioxide which is captured and processed. In addition to generating a needed domestic energy source, the gas production plant will have other significant benefits including: 6 t Producing a high grade compost which can be used in agriculture, land recla- mation, landscaping, golf courses, gardening, greenhouses, erosion preven- tion and mitigation; e Capturing carbon dioxide which is a "greenhouse gas" for use in medical ap- plications, welding, refrigeration and other uses. • By using cattle manure, food wastes and other organic wastes as feed stocks, the digester facility will help preclude release of pollutants to the environment and, in particular, will preclude the emission of significant amounts of nitrous oxide A temporary batch plant will be located on-site during construction. Some 30 - 40 truckloads per day of aggregate, cement, etc. are expected, with 10 - 15 worker vehicles. Construction will be complete prior to the start of routine operations. Since construction traffic will be temporary and significantly less than normal operating traffic, it is not considered critical Routine site activity is expected to start in 2010 at about 50% and increase to full production about 6 months later. Given the short time between start up and full production, the site is assumed at full production at the onset of operations. Heart- land will operate this facility 24 hours per day with three work shifts each having 6 — 8 employees. Shift times are expected to be from 7:00 AM — 3:00 PM, 3:00 PM — 11:00 PM and from 11:00 PM - 7:00 AM. At full operation, the facility will generate some 70 — 90 trucks per day with relatively equal distribution over the 24 hour work- day. Site visitors will be minimal with only 1 - 2 visitors per day. Peak site traffic will occur during shift changes. During these times 20 site trips are expected with a trip representing either an inbound or outbound traffic movement. Daily site traffic is expected to be 205 trips. The site will be served by a driveway along the west side of CR 49. It will be located about 900 feet north of CR 40 and will have with one lane in each direction. The 7 driveway will be paved as required by County standards. A field review of sight distance at the site driveway location was conducted. It was determined that with the driveway located on the roadway crest, about 900 feet north of CR 40, sufficient sight distance will be easily available. A concept plan for the Heartland site is provided on Figure 4. Site traffic is expected to arrive and depart the site equally to/from the north and south on CR 49. Anticipated site traffic shown on Figure 5. IV. FUTURE CONDITIONS A). Background Traffic Background traffic was developed using straight-line growth based on County growth factors contained in the Upper Front Range Regional Transportation Plan. Background peak hour traffic is shown on Figures 6 and 7 for the short-term (201 0) and long-term (2029) time frames, respectively. B). Total Traffic Total traffic (the combination of site traffic and background traffic) was developed for each future evaluation year. This information is shown on Figure 8 for the short-term and on Figure 9 for the long-term. 8 — I 1 - - hi?( ,{G 6)'.a l L(£1 it;i5 X61 i nom, mY.o tr3.rou,.-n,'r 54 '05 6()]Z-JU]cuJ(')u S Yt•,�i l{()At vrtc.aj tIIHxaix...�'.1 r.,nuvrnI.v au a uir+ ,_ r.d a�rsv�iraasoaax =I flsl! 11 a j, (?2i f1'j` t!_�: l ADS-AN-A RIaielt Ralf GKV-L.2[V--3N fI; {:III. _ I II i I, 4 ; s ! i : i r >,. . g l _ - - i :a Q I a.)

Figure 9 LONG-TERM TOTAL TRAFFIC 14 -�. C). Roadway System Short-term and long-term roadway features were estimated using known major im- provements (roadway widening, etc) along CR 49. Since no major improvements are anticipated, the existing roadway geometry was assumed through the long term. VI.TRAFFIC IMPACTS In order to assess operating conditions with the Heartland facility fully operational, highway capacity analyses were conducted at the site access intersection. Short- and long-term conditions were evaluated. At the onset of these undertakings, peak hour traffic was reviewed at each intersec- tion to identify the need for new auxiliary lanes or an upgrade in traffic controls. Findings for each time frame are documented in the following sections. A). Short Term A review of peak traffic was conducted to determine the need for auxiliary lanes at the CR 49 — site access intersection. CDOT's State Highway Access Code auxiliary lane criteria for R-B roadways and the existing 65 MPH speed limit were used in this assessment. It was determined that site traffic will not be high enough to warrant any auxiliary lanes at this intersection. Consequently, the short-term roadway geometry shown on Figure 10 is appropriate. This reflects existing conditions supplemented by the site driveway. Short-term operating conditions were evaluated at the driveway using highway capacity analysis procedures. Resultant 2010 levels of service with the Heartland facility fully operational are shown below. 15 rn ct 4/I SITE Access `5'°P 4 A 110'; --CR 40 Figure 10 SHORT-TERM ROADWAY GEOMETRY16 l SHORT-TERM OPERATIONS WITH HEARTLAND • Movement/ Level of Service ' Intersection Control j Direction AM ! PM I CR 49 — Access Stop NB LT A A EB LR B B As shown, very acceptable operations are expected with the facility fully operational. Capacity worksheets are presented in Appendix C. B). Long Term A review of long-term peak hour traffic determined that no new turn lanes will be warranted at the CR 49 -- site access intersection with Heartland fully functional. Consequently, the short-term roadway geometry was retained through the long-term. Long-term total peak hour traffic was loaded onto the short-term roadway geometry to reflect conditions in 2029. Resultant operating levels of service are shown below. LONG-TERM OPERATIONS WITH HEARTLAND Movement/ Level of Service Intersection Control Direction AM PM CR 49 — Access Stop NB LT 1- A A l EBLR As indicated above, the site access intersection will operate very acceptably in the long-term. Capacity worksheets are available in Appendix D 17 VII.CO NCLUSICNS Based upon the above documented investigations and analyses, the following can be concluded. • At full operation, the Heartland project will generate a minor amount of traf- fic with only 20 peak hour trips and 205 trips per day. These trips can be easily managed. • No improvements are needed to serve this development. • Site traffic can be accommodated by the existing roadway geometry at the CR 49 — site access intersection. c With this development level of service 'B' or better is expected for all peak hour traffic movements at the CR 49 — site access intersection through the long term. Accordingly, very acceptable operations are expected for the fo- reseeable future. Long term conditions will, in fact, closely replicate current conditions. • Sufficient intersection sight distance is expected at the planned site access location to CR 49. O The Heartland development is viable from a traffic engineering perspective. In summary, the existing roadway geometry supplemented by the site access to the west of CR 49 will facilitate acceptable operations for the foreseeable future. 18 APPENDIX A to b f--- V' O ti CO O 0) CO CO C.")

NAL ENG\`' to Chad TeVelde, PE AGPROfessionals AGPROfessionats _ 5 A-1 Organics—Digester Processing System Design and Operations Plan Executive Summary Heartland Biogas, LLC ("Heartland" or "HBG") owns and will operate an anaerobic digester facility located in southeast Weld County, Colorado. Anaerobic digestion of organic wastes in a controlled environment yields environmentally sound products for beneficial reuse. This facility will use agricultural wastes which include cattle manure from animal feeding operations and other organic residuals ("substrate"). A-1 Organics will own and operate the Digester Processing System (DPS) that will receive digester substrates for additional processing prior to delivery to the Heartland Biogas (HBG) facility digester system. These incoming substrates will be documented, particle size reduced, hydrated, blended as needed, and transferred to the HBG digester system under agreement. This A-1 Organics Digester Processing System Engineered Design and Operation Plan (EDOP) was prepared as an addendum to the Heartland Biogas, LLC Engineering, Engineered Design and Operation Plan. The sections that are applicable to the DPS facility have been included in this EDOP addendum. If the section was not changed from the Heartland EDOP it is noted as "No Change" at the section header.

Introduction This EDOP addendum has been prepared pursuant to the Colorado Regulations Pertaining to Solid Waste Disposal Sites and Facilities 6-CCR 1007-2 (Regulations), Section 14 for Class I Composting Facilities, Section 8 pertaining to Recycling Facilities, Section 11 for Waste-to- Energy Facilities, and Section 9 for Waste Impoundments for review and approval by the Colorado Department of Public Health and Environment (CDPHE) and Weld County Department of Public Health and Environment (WCDPHE). The intent of this EDOP is to protect the environment and citizens of Colorado by documenting the design, control, and management measures to prevent ground and surface water impacts, prevent nuisance conditions, and properly decommission the site in the event of facility closure. A-1 Organics is proposing a Digester Processing System (DPS) that will receive digester substrates. These incoming substrates will be documented, particle size reduced, hydrated, and blended as needed prior to transferring to Heartland Biogas (HBG) facility digester system or other off-site facility. The system is designed in accordance with all relevant federal, state and local requirements including, but not limited to, the requirements of the State of Colorado, Weld County, health laws, standards, rules and regulations of CDPHE's Hazardous Materials and Waste Management Division, Water Quality Control Division, and Air Pollution Control Division. The system shall comply with local building codes, fire codes, safety codes, and in accordance with applicable engineering and construction codes and standards. A.

Boring locations A geotechnical site exploration was conducted by Soilogic in October 2014 for the DPS site (See Appendix 3). Two borings were advanced to a depth of 30 feet beneath the proposed DPS location. Reportedly, groundwater was not encountered in the B-2 boring. Groundwater was encountered in the B-1 boring at a depth of approximately 29 feet below ground surface (bgs). Twenty-four hours following drilling, static water level in the B-1 boring was measured at 27.5 feet bgs. See Appendix 3 referenced above for maps of the boring locations and detailed findings. This site is located in the Beebe Draw tributary of the South Platte Basin above the Laramie-Fox Hills Alluvial Aquifer. This confined aquifer occurs primarily in the lower sandstone units of the Laramie Formation and the upper sandstone and siltstone units of the underlying Fox Hills AGPROfessionals _ _� In A-1 Organics-Digester Processing System - Design and Operations Plan sandstone. The geological formations of this aquifer are primarily composed of Cretaceous and Tertiary sandstone, conglomerate and shale. The thickness of the aquifer ranges from zero at the boundary to between 200-300 feet in the central part of the basin. The Laramie Fox Hills Aquifer is underlain by nearly impermeable Pierre shale and on top consists of fine, to very fine, grained sandstone or siltstone imbedded in the shale. Groundwater within the Laramie-Fox Hills Aquifer tends to contain small amounts of dissolved solids with concentration ranges from 200 to 2,000 milligrams per liter. Some gases, such as hydrogen sulfide and methane exist within the aquifer. The edges of the aquifer tend to have hard water, consisting of a sodium bicarbonate or sulfate. Depth to alluvial groundwater within the aquifer generally ranges up to 250 feet. The preliminary geotechnical report (Appendix L) did not indicate any groundwater within 25 feet of the existing grade surface. Subsequent drilling identified alluvial water at a depth of 42 feet in the center of the site. Several nearby wells indicate depth to groundwater ranges from 70- 200 feet bgs. if. Site Soils A Soils Report from the Natural Resources Conservation Service is provided to describe types of soils and engineering properties of the soils on the site (See Appendix G). Approximately three to six inches of topsoil and vegetation were encountered at the surface during drilling. Beneath that was light brown to brown silty sand and sandy lean clay. The three main strata were classified as a fine silty sand, then sandstone to clayey sand in places, with a elaystone layer existing between 25-50 feet. The silty sand was generally medium dense to dense with occasional loose zones and showed low swell and low to moderate settlement potential with an increase in moisture content at current moisture and density conditions. The sandy lean clay/clayey sand conglomerate was generally very stiff to hard in terms of consistency and/or medium dense to dense in terms of relative density and showed low swell potential and low to moderate consolidation potential at in-situ conditions. The silty sand and sandy lean clay/clayey sand conglomerate extended to the bottom of borings B-3, B-4, B-5 and B-8 at a depth of approximately 25 feet bgs. At boring locations B-1, B-2, B-6, B-7, B-9, B-10, B-11, the silty sand and sandy lean clay/clayey sand conglomerate extended to depths ranging from approximately 18 to 29 feet bgs and was underlain by brown/grey/rust claystone which varied to siltstone/sandstone in places. The claystone with siltstone/sandstone was medium to very hard and showed low to high swell potential at in-situ moisture and density conditions. Borings B-1, B-2, B-6, B-7, 13-9, B-10, B-11, were terminated at depths ranging from approximately 25 to 45 feet bgs in the claystone with siltstone/sandstone bedrock. Natural Resource Conservation Service's (NRCS) soil report classified these soils as Valent sand and Vona loamy sand. Run-off potential from this site is considered to be low because the soils are classified as well drained to excessively drained (See Appendix G).

Surface Water & Groundwater Protection — No Change a) Run-on, Run-off- No Change b) Wastewater Ponds - No Change c) Secondary Containment In-process materials located in both the low solids liquid storage tanks and the 227,800 gallon substrate storage tank have secondary containment. The tanks will be placed on top of and surrounded by 60 mil HDPE liner protected by an earthen blanket. A containment wall designed for 110% containment of the largest tank will be constructed surrounding the tank battery(See Appendix 4). The tanks and containment area will be visually inspected for leaks monthly. See attached drawings for tank cross section details (Appendix 5). In the event of a catastrophic tank failure, waste will be removed from the secondary containment as soon as possible, not to exceed 48 hours. Clean-up will follow the procedures detailed in the contingency plan. Substrate processing pit design has secondary containment comprised of a sprayed on rubber like membrane on the interior walls of the concrete pit. The membrane will be inspected for integrity on a monthly basis, and the concrete in ground structures will be designed to hold water without coating. 3. Process A.

General Substrate Processing The digester processing system receives digester substrates requiring additional processing and or blending prior to delivery to the HBG Digester System. The incoming substrates are AGPROfessionals 12 A-] Organics—Digester Processing System Design and Operations Plan inspected, recorded, reduced, hydrated, and then blended as needed. The product is then transferred to the HBG biogas digesters. The DPS anticipates having the capacity to process and transfer up to 350,000 gallons per day of various digester substrates. The DPS will consist of three (3) 30,000 gallon (+-) in-ground concrete processing tanks identified as: Tiger de-packaging tank (Tiger), DODA and Non-DODA (Appendix 6). Each concrete tank will have a mixing and/or transfer pump (Appendix 7). The Tiger tank receives de-packaged substrates produced by the Tiger unit, the DODA tank will receive source separated substrates requiring further processing through the DODA bio-separator. The Non-DODA tank will receive substrates that do not require processing through the Tiger and/or DODA, but may require additional particle size reduction and/or blending prior to delivery to the HBG digester system. Substrates in the tanks will be similar to but exclusive to the substrates described above. Incoming substrates will be transferred to the unloading pad and directed to the appropriate processing vault via the press grate and the cascading transfer augers. Additionally, the DODA and Non-DODA tank will have a secondary drop location to provide contingent unloading options. The Tiger and DODA are employed to remove packaging and other incidental materials such as plastics from the substrates prior to delivery of the substrates to the HBG system. Separated packaging and other materials removed by the Tiger and/or DODA will be recycled and or disposed of at an appropriate landfill facility. The substrates produced by the Tiger will be transferred to the tank for additional processing and blending. The DODA Bio-separator and Tiger machine will be located in a 73-foot by 70-foot coverall building, on a sloped concrete pad surrounded by small curbs to prevent any unwanted spread of product. Concrete pad will drain back to the concrete tanks. There will be as many as six (6) tanks that can store fresh water, south pond water, centrifuge water, and/or other low solid substrate liquids required for hydration and blending requirements. The on-site 227,800 gallon vertical steel tank will store processed substrate material until transferred to the HBG digester system. 9. Feedstock Receiving Digester substrates will be placed on or near the press plate located on the concrete receiving pad. Operational procedures shall be to push the materials through the press plate with machinery into the cascading augers. The cascading augers provide for initial particle size reduction and slicing prior to delivery to the transfer auger. The transfer auger moves material to the appropriate processing tank. Alternatively, substrates can be directly placed into the desired processing tank via a secondary drop. Low solid substrates that are used for hydration can be unloaded directly into the appropriate tank. Packaged materials targeted for de-packaging by the Tiger will be temporarily stored in a designated area in the coverall building until processed. As appropriate, hydration water or low solid substrates may be added at the transfer auger or directly into the processing tank. A mixing pump will assist to mix and slurry the material. As tanks become full, a valve is operated, and the mixing pump transfers prepared substrates to the digester system.

Tanks shall be visually inspected for integrity during wash-downs. ii. Water and Paunch/Processed Substrate Tank Leak Detection Water storage tanks and substrate storage tank leak detection will be provided by visual inspection. If liquid is present in the containment area and is deemed to be possible substrate per visual inspection, it will be sampled to verify substrate is present. Documentation of these inspections will be placed in the system's operations records. The system operator shall provide written notification to the CDPHE within seven days of substrate liquid in the leak detection system. If this sampled liquid is found to be substrate liquid, a report summarizing the management of the liquid from the leak detection system, including volume of liquid removed, analytical test results, and liquid disposition, shall be drafted. The report will also include repairs performed on the leaking tank. The report shall be provided to the CDPHE within thirty days of receiving analytical results or completion of repairs.

B. Water Quality - No Change C. Air Quality Permits - DPS to be Incorporated into Heartland Minor Source Air Permit 1. Expected Air Permit Type: Minor Source Air Permit The DPS is to be incorporated into the Heartland Minor Source Air Permit. Colorado regulations note that an air emissions source is minor if it can be proved that emissions of criteria air pollutants will be less than 100 tons per year(http://www.eea-inc.com/rrdb/DGRegProject/ States/Newsite/COrevised.html#emission). A description of the DPS system is to be submitted to the CDPHE; no new sources of air emissions are expected to be added to the Minor Source Air Permit that is associated with the facility, with the exception of the possibility of additional particulate matter(TSP, 10 and 2.5) from the disturbance of land in the construction of the DPS. D. Colorado Department of Agriculture - No Change 1 " The Colorado Department of Public Health and Environment, Hazardous Materials and Waste Management Division (the "Division")views the addition of the DPS is an operational issue, and not a substantial change to the provisions of the Certificate of Designation (CD). Therefore, the Division does not consider changes to the Heartland CD as being necessary." CDPHE correspondence to Weld County dated October 8, 2014.

(Soilogic) personnel have completed the geotechnical subsurface exploration you requested for the proposed Digester Processing System(DPS) facility to be constructed at the Heartland Renewable Energy site in Weld County, Colorado. The results of our subsurface exploration and pertinent geotechnical engineering recommendations are included with this report. We understand this project involves the construction of several above and below grade water tanks and associated pumping works and support improvements including a concrete pad and office structure at the Heartland Renewable Energy facility, located at 19179 County Road 49 in LaSalle, Weld County, Colorado. The main storage tank (200,000 gallons) is expected to be approximately 36 feet in diameter and approximately 25 feet in height. We understand a ring-wall foundation is the preferred method for support of the 200,000 gallon tank. Several smaller and more lightly loaded rectangular storage tanks are anticipated including several buried 16-foot cubical tanks and 32,000 gallon rectangular tanks with approximate plan dimensions of 12 feet by 40 feet and approximately 6 feet in height. Foundation loads for the 200,000 gallon tank are expected to be light to moderate with the tank bottom exerting approximately 2000 psf on the supporting soils. Foundation loads for the remaining area improvements are expected to be light with rectangular tanks exerting approximately 500 psf on the supporting soils and other structure loads estimated at continuous wall loads less than 3 kips per lineal foot and individual column loads less than 50 kips. Small grade changes are anticipated to develop finish site grades in the DPS area Soilogic, Inc. 3050 67th Avenue, Suite 200•Greeley, CO 80634•(970) 535-6144 P.Q.

Colorado Soilogic# 141208 2 The purpose of our exploration was to describe the subsurface conditions encountered in the completed site borings and develop the test data necessary to provide recommendations concerning design and construction of storage tank and associated support equipment foundations and support of a concrete pad and exterior flatwork. The conclusions and recommendations outlined in this report are based on results of the completed field and laboratory testing and our experience with subsurface conditions in this area. SITE DESCRIPTION The DPS area is situated on the south-central portion of the Heartland Renewable Energy site, located at 19179 County Road 49 in LaSalle, Weld County, Colorado. At the time of our site exploration, the proposed construction area had been stripped of topsoil and vegetation and was relatively flat, with the maximum difference in ground surface elevation across the proposed construction area estimated to be less than 2 feet. Evidence of prior building construction was not observed in the proposed construction area by Soilogic personnel at the time of our site exploration. EXPLORATION AND TESTING PROCEDURES To develop subsurface information in the area of the proposed DPS improvements, two (2) soil borings were advanced to depths ranging from approximately 25 to 30 feet below present site grades within the proposed improvement area. The approximate locations of proposed site improvements were premarked in the field by surveyors. The boring locations were established in the field by Soilogic personnel based on the premarked areas. A diagram indicating the approximate boring locations is included with this report. A graphic log of each of the auger borings is also included. The test holes were advanced using 4-inch diameter continuous flight auger powered by a truck-mounted CME-55 drill rig. Samples of the subsurface materials were obtained at regular intervals using California barrel sampling procedures in general accordance with ASTM specification D-1586. As part of the D-1586 sampling procedure, the standard sampling barrel is driven into the substrata using a 140 pound hammer falling a distance Geotechnical Subsurface Exploration Report Digester Processing System(DPS) 4.Heartland Renewable Energy (19179 County Road 49) LaSalle,Weld County, Colorado Soilogic#14-1208 3 of 30 inches. The number of blows required to advance the samplers a distance of 12 inches is recorded and helpful in estimating the consistency, relative density or hardness of the soils or bedrock encountered. In the California barrel sampling procedure, lesser disturbed samples are obtained in removable brass liners. Samples of the subsurface materials obtained in the field were sealed and returned to the laboratory for further evaluation, classification and testing. The samples collected were tested in the laboratory to measure natural moisture content and visually classified in accordance with the Unified Soil Classification System(USCS). The USCS group symbols are indicated on the attached boring logs. An outline of the USCS classification system is included with this report. Classification of bedrock was completed through visual and tactual observation of disturbed samples. Other bedrock types could be revealed through petrographic analysis. As part of the completed laboratory testing, a calibrated hand penetrometer (CHP) was used to estimate the unconfined compressive strength of essentially cohesive specimens. The CHP also provides a more reliable estimate of soil consistency than tactual observation alone. Dry density, -200 wash and swelllconsolidation tests were completed on selected samples to help establish specific soil characteristics. The percent passing the#200 size sieve (-200 wash test) is used to determine the percentage of fine grained soils (clay and silt) in a sample. Swell/consolidation tests are performed to evaluate soil volume change potential with variation in moisture content. The results of the completed laboratory tests are outlined on the attached boring logs and swelllconsolidation summary sheets. SUBSURFACE CONDITIONS The subsurface materials encountered in the completed site borings can be summarized as follows. Light brown to brown silty sand was encountered at the surface at the boring locations. The silty sand was medium dense in terms of relative density, exhibited low swell potential at in-situ moisture and density conditions and extended to a depth of approximately 14 feet below ground surface at the location of boring B-1. At boring location B-2, the silty sand extended to a depth of approximately 6 feet below ground surface and was underlain by brown to reddish brown/olive sandy lean clay. The lean clay was very stiff in terms of consistency, exhibited low swell potential at current Geotechnical Subsurface Exploration Report Digester Processing System(DPS) @ Heartland Renewable Energy (19179 County Road 49) LaSal le,Weld County, Colorado Soilogic# 14-1208 4 moisture and density conditions and extended to a depth of approximately 14 feet below ground surface. The silty sand and sandy lean clay soils were underlain by grey/olive/brown siltstone/sandstone bedrock with occasional claystone interbeds. The siltstone/sandstone varied from hard to very hard in hardness, exhibited low swell potential at in-situ moisture and density conditions and extended to the bottom of both borings at depths ranging from approximately 25 to 30 feet below ground surface. The stratigraphy indicated on the included boring logs represents the approximate location of changes in soil and bedrock types. Actual changes may be more gradual than those indicated. At the time of drilling, groundwater was encountered at boring location B-1 at a depth of approximately 29 feet below ground surface. Groundwater was not encountered at boring location B-2 at that time. When checked approximately 4 days after drilling, groundwater was measured at a depth of approximately 27'/ feet below ground surface at boring location B-1. Boring B-2 had dry caved at a depth of approximately 21 feet below ground surface at that time. Groundwater levels will vary seasonally and over time based on weather conditions, site development, irrigation practices and other hydrologic conditions. Perched groundwater conditions may also be encountered at times throughout the year. Perched water is commonly encountered in soils overlying less permeable soil layers and/or bedrock. The location and amount of perched water can also vary over time. ANALYSIS AND RECOMMENDATIONS Site Development Any existing topsoil and vegetation should be removed from all proposed fill and improvement areas. After stripping and completing all cuts and prior to placement of any fill or flatwork improvements, we recommend the exposed subgrade soils be scarified to a depth of 9 inches, adjusted in moisture content and compacted to at least 95% of the material's standard Proctor maximum dry density. The moisture content of the scarified soils should be adjusted to be within the range of ±2% of standard Proctor optimum Geotechnical Subsurface Exploration Report Digester Processing System(DPS) (a)Heartland Renewable Energy (19179 County Road 49) LaSalle, Weld County, Colorado Soilogic 4 14-1208 5 moisture content at the time of compaction. Fill soils required to develop the site should consist of approved, low volume change (LVC) soils free from organic matter, debris and other objectionable materials. The site silty sand and sandy lean clay could be used as fill in this area. Suitable fill and backfill soils should be placed in loose lifts not to exceed 9 inches thick, adjusted in moisture content and compacted as recommended for the scarified soils above. Care should be taken to avoid disturbing reconditioned subgrades and site fill soils prior to placement of foundation and flatwork concrete. Soils which are allowed to dry out or become wet and softened or disturbed by the construction activities should be removed and replaced or reworked in place prior to concrete placement. Foundations Based on the materials encountered in the completed site borings and results of laboratory testing, it is our opinion the proposed 200,000 gallon storage tank could be supported on a ring-wall foundation and other more lightly loaded tanks and support structures could be supported by continuous spread footing and isolated pad foundations bearing on natural, undisturbed silty sand, sandy lean clay or siltstone/sandstone bedrock with low volume change potential. Each site structure should be supported on like materials in order to reduce the potential for excessive differential movement. If differential foundation bearing conditions are observed at the time of construction, extending footing foundations to bear on similar soils/bedrock at greater depth or development of a uniform thickness of overexcavation/backfill beneath spread footing foundations would be required. We recommend staged loading of the 200,000 gallon tank be completed upon initial filling to allow for monitoring of total and differential foundation settlement. For design of the 200,000 gallon storage tank ring-wall spread footing foundation and other more lightly-loaded tank and structure foundations bearing on natural, undisturbed, medium dense silty sand and/or very stiff sandy lean clay with low volume change potential, we recommend using a maximum net allowable soil bearing pressure of 2,000 psf. Geotechnical Subsurface Exploration Report Digester Processing System(DPS)(0 Heartland Renewable Energy (19179 County Road 49) LaSalle,Weld County, Colorado Soilogic# 14-1208 6 Exterior footings should bear a minimum of 30 inches below finished adjacent exterior grade to provide frost protection. We recommend formed strip footings have a minimum width of 12 inches and isolated pad foundations have a minimum width of 24 inches in order to facilitate construction and reduce the potential for development of eccentrically loaded footings. Actual footing widths should be designed by a structural engineer. For design of footing foundations and foundation walls to resist lateral movement, a passive equivalent fluid pressure value of 250 pcf could be used. The top 30 inches of subgrade could be considered a surcharge load but should not be used in the passive resistance calculations. A coefficient of friction of 0.45 could be used between foundation and floor slab concrete and the bearing soils to resist sliding. The recommended passive equivalent fluid pressure value and coefficient of friction do not include a factor of safety. We estimate settlement of the 200,000 gallon storage tank designed and constructed as outlined above and resulting from the assumed structural loads would be 2'/2 inches or less. If this amount of settlement must be reduced, overexcavation/backfill procedures or other alternative deep foundation systems could be employed. Removal of the upper 5- feet of silty sand and replacement with select granular fill compacted to at least 100% of the material's standard Proctor maximum dry density and within+2% of standard Proctor optimum moisture content would be expected to reduce the anticipated settlement of the 200,000 gallon storage tank to 13/ inch or less. We estimate settlement of the 32,000 gallon above-ground storage tanks and other lightly-loaded spread footing foundations designed and constructed as outlined above and resulting from the assumed structural loads would be less than 1 inch. We estimate settlement of the buried storage tanks resulting from the assumed structural loads would be 1/2 inch or less. Differential settlement would be expected to be more limited, approaching 75% of the total settlement estimated above. If water from any source is allowed to infiltrate the foundation bearing soils, additional movement of foundations could occur. Seismicity Based on our review of the International Building Code (2003), a soil profile type C could be used for the site strata. Based on our review of United States Geologic Survey Geotechnical Subsurface Exploration Report Digester Processing System(DPS) Heartland Renewable Energy (19179 County Road 49) LaSalle,Weld County, Colorado Soilogic#14-1208 7 (USGS) mapped information, design spectral response acceleration values of SDs = .193 (19.3%) and SDI = .087 (8.7%) could be used. Concrete Pad and Exterior Flatwork The concrete pad and exterior flatwork could be supported directly on the reconditioned natural site soils and/or properly placed and compacted fill soils developed as outlined in the "Site Development" portion of this report. A modulus of subgrade reaction (k) value of 150 pci could be used for design of slabs supported on the native silty sand and sandy lean clay soils. Disturbed subgrades or subgrade materials that have been allowed to dry out or become wet and softened should be removed and replaced or reconditioned in place prior to pad and exterior flatwork construction. Drainage Positive drainage is imperative for satisfactory long-term performance of the proposed site improvements. We recommend positive drainage be developed away from the structures during construction and maintained throughout the life of the site improvements, with twelve (12) inches of fall in the first 10 feet away from the tanks and associated site improvements. Shallower slopes could be considered in hardscape areas. In the event that some settlement of the backfill soils occurs adjacent to the tanks, the original grade and associated positive drainage outlined above should be immediately restored. We recommend irrigation systems (if any) be placed a minimum of 5 feet away from the perimeter of the site structures and be designed to discharge away from all site improvements. Water which is allowed to pond adjacent to site improvements can result in unsatisfactory performance of those improvements over time.

DESCRIPTIVE SOIL CLASSIFICATION: Soil classification is based on the Unified Classification System. Coarse Grained Soils have more than 50%of their dry weight retained on a#200 sieve; their principal descriptors are: boulders, cobbles,gravel or sand. Fine Grained Soils have less than 50%of their dry weight retained on a#200 sieve;they are principally described as clays if they are plastic, and silts if they are slightly plastic or non-plastic. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse-grained soils are defined on the basis of their in-place relative density and fine-grained soils on the basis of their consistency.

The Colorado Department of Public Health and Environment, Hazardous Materials and Waste Management Division (the"Division") views the addition of the DPS is an operational issue, and not a substantial change to the provisions of the Certificate of Designation (CD). Therefore, the Division does not consider changes to the Heartland CD as being necessary. Should you have any questions regarding this letter, i may be reached by phone at 303-692-3384 or email at larry.bruskin@state.co.us. Sincerely, Lawrence J. Bruskin, P.E.

In the event of poor economic or market conditions it may be necessary for A-1 to suspend operation of the facility. At such time that operations are suspended, the Closure Plan shall be implemented. In the event that it becomes necessary to suspend operation of the facility including the discontinued receipt, processing and sale of materials for more than 180 days, or otherwise approved by CDPHE, A-i shall notify CDPHE and Weld County and begin the implementation of the Closure Plan in accordance with 6 CCR 1007-2 Sec. 14.8.2 to maintain safe environmental conditions. A-1 shall provide CDPHE and Weld County written notification within fourteen(14) calendar days of commencing the implementation of the Closure Plan in accordance with 6 CCR 1007-2 Sec. 14.8.4. A-1 shall provide CDPHE and Weld County written notification within thirty(30)calendar days documenting that all of the requirements and conditions of the Closure Plan have been achieved in accordance with 6 CCR 1007-2 Sec. 14.8.5. Following the closure of the facility a notation shall be recorded on the property deed notifying any potential purchaser that the property has been used as a composting facility in accordance with 6 CCR 1007-2 Sec. 14.8.6. The following closure tasks shall be completed within ninety(90) days unless an extension is granted by CDPHE and Weld County. This extension request would be necessary if the closure will take more than ninety(90) days for A-1 to complete all necessary measures to prevent threats to human health and the environment. Closure: Removal of Residual Materials from Digesters and Storage Tanks All stored raw materials and substrate will be used in the on-site digestion process to completion. However, the DPS is not dependent on the digester system to operate and would continue operations if the digester facility were to shut down. Processed material would be shipped to an alternative A-1 facility approved to receive the substrates until the on-site digester is ready to receive material again. Permanent Closure: After all digester processing activities have been completed, each process vessel shall be cleaned of any environmental hazards. The cleaning process will include washing the walls, floors, and any mechanical apparatus within the vessel with a high pressure water system or a high volume water system, and the residual wash water will be pumped to the effluent storage pond. At the end of the five (5) year temporary shut-down the facility shall be permanently closed. The following procedures will be followed to complete the permanent closure. A-1 Organics DAS Financial Assurance November 19,2014 Page 3 of 4 Storage Tanks At the end of this five year period, if permanent facility closure is eminent, all tanks, including the Tiger, DODA and Non-DODA tanks and substrate storage tanks, may remain intact and available for sale and use by another business. Post Closure: Following permanent closure of the DPS, A-1 shall conduct post-closure care in accordance with 6 CCR 1007-2 Sec. 14.9.1 by monitoring the site. In conjunction with the post-closure care, A-1 will maintain the facility to meet the Weld County Use by Special Review #1704 Development Standards including building and facility maintenance, weed control and facility security. Following permanent closure of the facility, Heartland Biogas (HBG)will conduct post-closure care in accordance with 6 CCR 1007-2 Sec. 14.9.1 and EDOP by monitoring the site. HBG will inspect and maintain the ground cover and vegetation indicated in their Closure Plan and will submit an annual report to CDPHE and Weld County detailing post-closure care activities during the prior year. In conjunction with the post-closure care, HBG will maintain the facility to meet the Use by Special Review and Weld County development standards, including building and facility maintenance, weed control and facility security. The post-closure care and maintenance period will be for a minimum of five (5) years unless HBG, after consultation with CDPHE, demonstrates that the reduced period is sufficient to protect human health and the environment in accordance with 6 CCR 1007-2 Sec. 14.9.2.
