Box 758 Greeley, CO 80632 Re: Final Agency Action: Certificate of Designation Recommendation of Approval with Conditions—Waste to Energy Design and Operation Plan — Revision#3 Heartland Renewable Energy, LLC Weld County, Colorado Dear Honorable Commissioners, The Colorado Department of Public Health and Environment ("CDPHE"), Hazardous Materials and Waste Management Division of("the Division") received on April 21, 2009 one copy of a Certificate of Designation ("CD") Application entitled "Waste to Energy Design and Operation Plan for Heartland Renewable Energy, LLC" ("the DOP") dated April 2009, submitted and prepared by AGPROfessionals, LLC ("AGPRO"). On May 15, 2009 via e-mail, the Division received official notification from the Weld County Department of Planning Services requesting the Division begin reviewing the document. The Division conducted a completeness review in accordance with procedures outlined in the Solid Waste Act ("Act"), CRS 30-20-101.5 et seq., and corresponding Regulations Pertaining to Solid Waste Sites and Facilities, 6 CCR 1007-2, Part 1 ("the Solid Waste Regulations"). In a letter dated May 27, 2009 the Division notified Heartland Renewable Energy, LLC ("HRE") that the DOP, as submitted, was incomplete. On June 18, 2009, the Division received one copy of Revision #1 to the DOP dated June 15, 2009. In its letter dated July 1, 2009 the Division notified HRE that the revised DOP was determined to be complete. PIA/it �eviec 2010-0774 Li�19�/G C(' .' Pt , H April 7,2010 Weld County Commissioners Final Agency Action: Certificate of Designation Recommendation of Approval with Conditions—Waste to Energy Design and Operation Plan—Revision#3 Heartland Renewable Energy, LLC Weld County, Colorado Page 2 The Division conducted its comprehensive technical review of Revision #1 of the DOP pursuant to the procedures outlined in the Act and the Solid Waste Regulations. The Division's preliminary comments and requests for additional information regarding Revision #1 were provided in its letter dated July 13, 2009. In response to the Division's July 13th letter, AGPRO prepared Revision #2 to the DOP dated September 15, 2009. Revision #2 was received by the Division on September 22, 2009. On September 27, 2009 the Division published a notice in The Greeley Tribune requesting public comments on the DOP. The public comment period ended October 27, 2009 with the Division receiving no comments. After reviewing Revision #2, the Division provided comments in a letter dated November 12, 2009. In a letter dated December 7, 2009, AGPRO provided responses to the Division's November 12th comments. The Division requested additional information and clarification via electronic mail dated December 18, 2009. The Division received via e-mail on January 12, 2010 and via regular mail on January 14, 2010 a letter dated January 11, 2010 from AGPRO which provided written responses and updated drawings. In its letter dated February 1, 2010, the Division approved, with modifications, the AGPRO letters dated December 7, 2009 and January 11, 2010, and the revised drawings dated January 6, 2010. The Division required FIRE to submit an updated DOP to the Division for its review and approval. On March 26, 2010 the Division received Revision #3 to the DOP dated March 19, 2010 ("Revised DOP"). The Division has reviewed the Revised DOP for technical merit. It is the determination of the Division that the proposed facility can comply with the technical, environmental, and public health standards in the Act and corresponding Solid Waste Regulations if the facility is constructed, operated, and monitored as detailed in the Application, and with the conditions of the Division as stated in this letter. Based on this assessment, the Division recommends, as final agency action, that this facility may be approved by Weld County, with the conditions set forth herein and with any additional local restrictions. The Division's approval of the Application has the following conditions that shall be incorporated into the CD when and if issued by Weld County. Please note that certain conditions listed below are included in the Revised DOP but are repeated herein for emphasis. 1. Prior to construction, HRE shall submit to the Division and Weld County for review and approval, a Construction Quality Assurance and Quality Control Plan ("CQA/QC Plan"), technical specifications, and construction drawings. The documents shall be submitted at least sixty(60) calendar days prior to commencement of construction. 2. Following construction, HRE shall submit to the Division and Weld County for review and approval a construction certification report, which includes construction record drawings, deviations from the approved plan, and results of all testing and documentation requirements set forth in the CQA/QC Plan. The construction certification report shall be submitted at least sixty (60) days prior to acceptance of feedstock.

Section 3.0(E)(1), Run-on, Run-off, includes the following statement: "The attached site map, indicates the preliminary grading contours and demonstrates how all runoff will flow toward a storm water retention pond to be constructed in the northwest corner of the property. " The "attached site map"refers to Sheet D-1, Revision #6 dated March 4, 2010 included at the end of the Revised DOP. 4. Section 3.0(E)(2), Wastewater Ponds, includes the following statement: "These ponds will be designed in accordance with Section 9 of the Solid Waste Regulations as Class II impoundments. The Groundwater Monitoring Plan has been implemented and groundwater monitoring wells are located to enable detection and assessment of the controlled seepage impact on groundwater. " Sheet MW-1 in the Groundwater Monitoring Plan shows existing monitoring well MW-2 within the footprint of a proposed reject-water storage pond. AGPRO has informed the Division the HRE plans to keep MW-2 at its current location and reconfigure/relocate the reject-water storage pond to avoid MW-2. The Division requires MW-2 to be located immediately down- gradient from (ie., as close as practical to) the reconfigured/relocated northern-most reject-water storage pond. Following the installation of proposed groundwater monitoring wells MW-4 and MW-5, HRE must submit boring logs and well completion information to the Division and Weld County. 5. Section 3.0(E)(5), Low Permeability Workpad, includes the following statement: "A non-permeable work pad will be located in the soil amendment delivery building where the de-watered digestate (soil amendment) will be contained after removal from the digesters, and prior to being relocated to the soil amendment storage area This non- permeable concrete pad and delivery building will contain daily batches of the initial 90- days of production of de-watered digestate, and will allow for adequate storage of this product while it is being analyzed A waiver request for a low permeable work pad for the area designated as soil amendment storage will be submitted to the Division and WCDPHE for approval, to be supported by the full analysis of the de-watered digestate product. " As a matter of clarification, HRE has indicated that it intends to use the Solids Dewatering Building (structure number 50) as the "soil amendment delivery building" during the initial 90 days of production. If the waiver request is denied, then HRE shall continue to use the Solids Dewatering Building for storage of soil amendment, or HRE shall construct low permeability work pads in the areas designated on the plans as "soil amendment storage." Should low permeability work pads become necessary, the design details, and any necessary revisions to the CQA/QC Plan must be submitted to the Division and Weld County for review and approval prior to construction of low permeability work pads.

Sections 4.0(B)(1) and (2), Inputs/Feed Stock, includes the following statement: HRE's digester facility will not accept hiosolids, or any other solids,processed soild waste, or sludge other than those described above at this time However, at such time that a Type III[sic]feedstock could be beneficially used in the digestion process, HRE shall provide all necessary documentation and request approval to accept the Type III[sic]feedstock. " The Division considers all of the proposed feedstock listed in Section 4.0(B)(2) of the Revised DOP as Type 1 and Type 2 as defined in Section 14.1.4 of the Solid Waste Regulations. As such, the proposed HRE facility is not currently approved to accept Type 3 feedstock. Section 14.1.4 of the Solid Waste Regulations defines Type 3 feedstock as: "Biosolids, solid waste,processed solid waste, and sludges. " Should HRE desire to accept certain Type 3 feedstock material in the future, HRE is required to update the facility's waste characterization plan pursuant to the requirements specified in Section 14.6.1(C) of the Solid Waste Regulations. The acceptance of Type 3 feedstock would be considered a significant change as defined in Section 1.3.9 of the Solid Waste Regulations. The updated waste characterization plan requires approval from the Division and Weld County prior to acceptance of Type 3 feedstock. 7. The Division approves the list of constituents presented in Table 1 on page 5 of the Groundwater Monitoring Plan. Because the Revised DOP limits the feedstock to Type 1 and Type 2 material, the Division agrees with the assessment of AGPRO that it is unnecessary to test ground water for total organic halogen, phenolic compounds, and organic constituents listed in Appendix IB of the Solid Waste Regulations. Should HRE seek approval for certain Type 3 feedstock in the future, the Division may require revisions to the groundwater testing requirements. 8. The facility shall comply with the 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 facility shall also comply with all local laws, ordinances, and CD conditions. As required by the Act, 30-20-I04(3)(a) and (3)(b), Weld County is obligated to notify its citizens and conduct a public hearing regarding the proposed solid waste facility. Please forward a copy of the County's final resolution concerning the CD issuance or denial to the Division. The Division is authorized to bill for its review of technical submittals pursuant to Section 1.7 of the Regulations. An invoice for the Division's review of the Revised DOP will be transmitted to Heartland Renewable Energy, LLC under separate cover. Should you have questions or comments, please call Curt Stovall at (303) 692-2295 or Roger Doak at(303) 692-3437.
