DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D The following descriptions of the site and the work are for the convenience of the successful Contractor (“Contractor”). All work will be governed by the CQAQC Plan, the Project Specifications, and the Project Drawings. Where there are differences between these documents, the order of precedence shall be the: • CQAQC Plan • Project Drawings • Project Specifications • Description of Work 2.0 Site Description The landfill site is located approximately two miles north-northeast of Wolcott, Colorado. Drawing No. 1 shows the location of the site in relation to vicinity features. The landfill is open to the public and serves all of Eagle County. The present site includes the existing landfill area, a leachate holding pond, a tire storage facility, surface water control features and structures, an office building/scale house, a maintenance shop, a Material Recovery Facility (MRF), and a Household Hazardous Waste Collection (HHWC) Facility. Please refer to Drawing No. 2 of the Project Drawings for existing conditions at the landfill. Water for construction (dust suppression, moisture conditioning soil, etc.) is not available on site. Water is available at the MSC Building located in Gypsum, Colorado or from the Eagle County Fairgrounds in Eagle, Colorado (47 miles and 30 miles round trip, respectively, from the project site). 3.0 Facility Responsibilities Eagle County or its Representative will survey to establish line and grade for construction and to determine quantities. This will include: • Control Points • Pre-construction and post-construction surveys for subgrade, clay liner, drainage layer, and operations layer to confirm lines and grades and for quantity determinations • As-built drawings Eagle County’s consultant, Souder Miller & Associates (SMA), will provide the aforementioned control points, pre-construction and post-construction surveys, and as-built drawings. Construction staking will not be Eagle County’s responsibility; the Contractor must provide their own construction staking. Any control points destroyed by the Contractor shall be replaced by the Contractor at Contractor’s expense. There is no specific soils report for the Mod 9 area. However, in the facility’s EDOP, it is stated that “Surficial sediments at the site generally consist of silty clays immediately underlain by weathered bedrock. These unconsolidated sediments range in thickness from as little as 6 inches to 45 feet.” Previous investigation at the site “indicates that unconsolidated clays are generally silty, brown to brownish-gray, and slightly damp. Previous investigation completed by Fox (White and Watermolen, 1985), which included geotechnical laboratory testing, described these surficial sediments as being high plasticity soils.” DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Subgrade elevations, clay liner grades, and drainage layer grades of Mod 9A must be certified by Eagle County or its Representative before work on the overlying layer may commence. The Contractor shall be invoiced for each post-construction survey that is not certified by Eagle County or its Representative. Eagle County or its Representative will provide the CQAQC Plan. The Plan includes specifications for testing equipment, supplies, and personnel for testing earth construction (moisture/density testing) and observing and documenting geosynthetics installation. 4.0 Contractor Responsibilities The Contractor shall be fully responsible for knowing and understanding the requirements of the work, including the CQAQC Plan, Project Specifications, and Project Drawings. Eagle County or its Representative will assist the Contractor with following and meeting the requirements of the CQAQC Plan, Project Specifications and Project Drawings, but Eagle County or its Representative shall not be responsible for informing the Contractor of the requirements. The Contractor shall provide all equipment, personnel, materials, and construction staking to complete the work to the line, grade and requirements included in this Description of Work, the CQAQC Plan, Project Specifications, and the Project Drawings. If the Contractor provides onsite fuel tanks, the tanks shall be double-walled or provided with acceptable secondary containment. The Contractor shall also provide portable toilets as necessary. Prior to beginning any work, the Contractor will provide a Health and Safety Plan (HASP) addressing the site-specific requirements of this work, including requirements for working in excavations and around landfills (managing refuse and potential leachate, methane gas, etc.). This HASP shall be reviewed by Eagle County and/or its Representative, but the Contractor shall have sole responsibility for the health and safety of its employees and for completing the work in accordance with all local, state, and federal regulations. The Contractor shall protect existing vegetation, structures, equipment, utilities, pavement, and improvements that are not scheduled for demolition during the project. Any damage caused by the Contractor or its subcontractors shall be repaired or replaced equal to existing conditions, at the expense of the Contractor. The landfill will remain open during the construction period. The Contractor shall complete the work in a manner that causes the least possible interference with normal landfill operations.

Construction of Mod 9A includes: DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D • Excavation and fill, as necessary, of Mod 9A to the line and grades shown on Drawing No. 3 to reach subgrade design grades. Shale excavation is anticipated. • Exposure of existing liner system along west side of Mod 9A and subsequent tie-in of new Mod 9A clay liner to existing clay liner. Drawings No. 4 and 7. • Installation of leachate drainage layer and subsequent tie-in of new Mod 9A drainage layer to existing drainage layer. Drawing No. 5 and 7. • Installation of geotextile overlying the drainage layer and subsequent tie-in of existing geotextile overlying existing drainage layer to new Mod 9A geotextile. Details on Drawing No. 7. • Construction of an interim liner termination and stormwater control berm to minimize run-on into Mod 9A and direct it into existing site drainage. • Installation of operations layer overlying the geotextile. Details on Drawing No. 7. • Fertilization, seeding, and mulching, as needed. Soil testing shall be done by Eagle County or its Representative. The minimum frequencies of testing are specified in the CQAQC Plan. The Contractor shall assist Eagle County or its Representative with testing, as necessary, to properly complete all testing to the satisfaction of Eagle County or its Representative. This includes scheduling testing, stopping work in the areas to be tested, as necessary, and preparing areas for testing (e.g., cutting or scraping flat areas for nuclear density testing). 6.2.2 Subgrade Excavation Excavation shall be observed by SMA and excavation conditions documented prior to clay liner construction. The subgrade shall be free of loose, saturated, or frozen soils, pooled water, and unstable materials prior to installation of clay liner. Proof-rolling with heavy equipment will be performed to identify any areas of undesirable material or soft soils and will be observed by SMA. Where unacceptable subgrade conditions exist, the surface will be re-rolled or over-excavated to reduce the impact of such conditions. When over-excavated, the resulting depression will be backfilled with structural fill. Backfilling will be accomplished in accordance with the CQAQC Plan. The completed subgrade will be surveyed to determine that the subgrade is in accordance with the Drawings. Portions of excavation may be extremely difficult due to the dense shale material found on-site. Excavation of this dense shale material may require additional equipment or personnel. Please provide a separate price for excavation of this dense shale material. The price will be utilized only when both Eagle County and the Contractor come to an agreement that field conditions necessitate additional equipment or personnel. Although boulders are not expected, please provide a separate excavation price in the event that boulders greater than 4-feet in diameter are discovered. After the subgrade has been tested (as appropriate), inspected, surveyed, and certified/approved as meeting the requirements of the CQAQC Plan, Project Specifications, and Project Drawings, the Contractor shall place clay liner and the drainage layer, including associated geotextile. After the liner components are installed, the soil cover (1-foot operations layer) shall be placed over the drainage layer geotextile. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 6.2.3 Clay Liner The clay liner shall be installed for Mod 9A using materials specified in the CQAQC Plan and Project Specifications. Prior to installing the clay liner, the prepared subgrade shall be observed by Eagle County or its Representative. Installation of the clay liner shall not begin until the underlying subgrade is approved by Eagle County or its Representative. Clay liner shall be constructed using on-site non-granular soils placed in loose 8-inch maximum lifts and compacted to a minimum of 92% maximum modified Proctor dry density between -2% and +4% of optimum moisture to reach a nominal hydraulic conductivity of at least 1x10-6 cm/sec. The Mod 9A clay liner must be properly tied into the existing liner system as detailed on Drawing No. 7 of the Project Drawings. Previous as-built liner in adjacent modules includes a one-foot thick clay liner and a 6-inch thick granular drainage layer. Mod 9A clay liner shall be placed in the locations and to the extent shown on Drawings No. 4 and 6 of the Project Drawings. As detailed on Drawing No. 7 of the Project Drawings, the clay liner shall be placed a minimum of 3.0 feet above the adjacent floor liner on excavation side walls (i.e., excavation slopes steeper than 4:1). This detail will apply to the area at the toe of slope along the south edge of Mod 9A. Sufficient soil to complete the clay liner is available on-site, located as shown on Drawing No. 2. 6.2.4 Leachate Drainage Layer The leachate drainage layer consists of a minimum 10-inch thick tire shreds layer exhibiting a minimum hydraulic conductivity of 1x10-2 centimeters per second (cm/sec). The County will have stockpiled materials meeting the requirement for the drainage layer. A 4 oz/sy non-woven geotextile shall be placed over the entire drainage layer, separating the drainage layer from the overlying waste (see Section 6.2.5). Work for the drainage layer shall not be considered complete until Eagle County or its Representative has observed and approved the work in writing. Please refer to Drawing No. 2 for location of tire shred stockpile and Drawings No. 5 and 7 for details. 6.2.5 Geotextile A 4 oz/sy non-woven geotextile shall be placed over the drainage layer. The geotextiles shall be installed using the materials specified in the CQAQCP. Alternate materials may be proposed by the Contractor; however, alternate materials shall not be used without written permission of Eagle County or its Representative. The geotextile shall be placed with the long dimension parallel to the slope, placed to minimize seams on slopes and near grade breaks, overlapped a minimum of three inches, and with seams jo ined by welding or sewing. 6.2.6 Operations Layer Twelve inches of operations layer material will be placed over the drainage layer and 4 oz/sy geotextile. This layer shall be constructed using the materials stockpiled by the County and placed in accordance with the CQAQCP. Prior to placing the soil operations layer over the geotextile, the geotextile shall be inspected by the County or its Representative. Overlying layers or materials shall not be placed on the geotextile until the geotextile is approved in writing by the County or its Representative.

EQUIVALENT MATERIALS AND EQUIPMENT: 6.11 Whenever materials or equipment are specified or described in the drawings or specifications by using the name of a proprietary item, or the name of a particular manufacturer, fabricator, supplier, or distributor, the naming of the item is intended to establish the type, function, and quality required. Unless the name is followed by words indicating that no substitution is permitted, materials or equipment of other manufacturers, fabricators, suppliers, or distributors may be accepted by ENGINEER and OWNER if sufficient information is submitted by CONTRACTOR to ENGINEER and OWNER to determine that the material or equipment proposed is equivalent to that named. The procedure for review by ENGINEER and OWNER will be as set forth in paragraphs 6.11.1 and 6.11.2 below. 6.11.1 Requests for review of substitute items of material and equipment will not be accepted by ENGINEER or OWNER from anyone other than CONTRACTOR in accordance with this Section 6.11.1. If CONTRACTOR wishes to furnish or use a substitute item of material or equipment, CONTRACTOR shall make written application to ENGINEER and OWNER for acceptance thereof, certifying that the proposed substitute will perform adequately the functions called for by the general design, be similar and of equal substance to that specified and be suited to the same use and capable of performing the same function as that specified. The application will state whether or not acceptance of the substitute for use in the Work will require a change in the drawings or specifications to adapt the design to the substitute and whether or not incorporation or use of the substitute in connection with the Work is subject to payment of any license fee or royalty. All variations of the proposed substitute from that specified shall be identified in the application and available maintenance, repair and replacement service will be indicated. The application will also contain an itemized estimate of all costs or savings that will result directly or indirectly from acceptance of such substitute, including costs of DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 12 redesign and claims of other contractors affected by the resulting change, all of which shall be considered by ENGINEER and OWNER in evaluating the proposed substitute. ENGINEER may require CONTRACTOR to furnish, at CONTRACTOR'S expense, additional data about the proposed substitute. ENGINEER and OWNER will be the sole judge of acceptability, and no substitute will be ordered or installed without ENGINEER’S and OWNER’s prior written acceptance. OWNER may require CONTRACTOR to furnish, at CONTRACTOR’S expense, a special performance guarantee or other surety with respect to any substitute. 6.11.2 ENGINEER will record time required by ENGINEER and ENGINEER'S consultants in evaluating substitutions proposed by CONTRACTOR and in making changes in the drawings or specifications occasioned thereby, whether or not ENGINEER accepts a proposed substitute. CONTRACTOR shall reimburse OWNER for the charges of ENGINEER and ENGINEER'S consultants for evaluating any proposed substitute. CONCERNING SUBCONTRACTORS: 6.12 CONTRACTOR shall not employ any Subcontractor or other person or organization (including those who are to furnish the principal items of materials or equipment), whether initially or as a substitute, against whom OWNER or ENGINEER may have reasonable objection. A Subcontractor or other person or organization identified in writing to OWNER and ENGINEER by CONTRACTOR prior to the Notice of Award, and not objected to in writing by OWNER or ENGINEER prior to the Notice of Award, will be deemed acceptable to OWNER and ENGINEER. Acceptance of any Subcontractor, other person or organization by OWNER or ENGINEER shall not constitute a waiver of any right of OWNER or ENGINEER to reject defective work. If OWNER or ENGINEER, after due investigation, has reasonable objection to any Subcontractor, or other person or organization proposed by CONTRACTOR after the Notice of Award, CONTRACTOR shall submit an acceptable substitute, and the Contract Price shall be increased or decreased by the difference in cost occasioned by such substitution, and an appropriate change order shall be issued. CONTRACTOR shall not be required to employ any Subcontractor, other person or organization against whom CONTRACTOR has reasonable objection. 6.13 CONTRACTOR shall be fully responsible for all acts and omissions of his Subcontractors, and of persons and organizations directly or indirectly employed by them, and of persons and organizations for whose acts any of them may be liable to the same extent that CONTRACTOR is responsible for the acts and omissions of persons directly employed by CONTRACTOR. Nothing in the Contract Documents shall create a contractual relationship between OWNER or ENGINEER and any Subcontractor or other person or organization having a direct contract with CONTRACTOR, nor shall it create any obligation on the part of OWNER or ENGINEER to pay or to see to the payment of any monies due any Subcontractor, or other person or organization, except as may otherwise by required by law. OWNER or ENGINEER may furnish to any Subcontractor or other person or organization, to the extent practicable, evidence of amounts paid to CONTRACTOR on account of specific Work done. 6.14 The divisions and sections of the specifications and the identifications of any drawings shall not control CONTRACTOR in dividing the Work among Subcontractors, or delineating the Work to be performed by any specific trade. 6.15 All Work performed for CONTRACTOR by a Subcontractor will be pursuant to an appropriate agreement between CONTRACTOR and the Subcontractor which specifically binds the DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 13 Subcontractor to the applicable terms and conditions of the Contract Documents for the benefit of the OWNER and ENGINEER.

All samples will have been checked by, and stamped with the approval of CONTRACTOR, identified clearly as to material, manufacturer, and any pertinent catalog numbers, and the use for which intended. 6.33 At the time of each submission, CONTRACTOR shall, in writing, call ENGINEER'S and OWNER’s attention to any deviations that the shop drawings or samples may have from the requirements of the Contract Documents. 6.34 ENGINEER with prior approval of OWNER will review and approve, with reasonable promptness, shop drawings and samples, but ENGINEER'S and/or OWNER’s review and approval shall be only for conformance with the design concept of the Project, and for compliance with the information given in the Contract Documents, and shall not extend to means, methods, sequences, techniques, or procedures of construction, or to safety precautions of programs incident thereto. The review and approval of a separate item as such will not indicate approval of the assembly in which the item functions. CONTRACTOR shall make any corrections required by ENGINEER or OWNER, and shall return the required number of corrected copies of shop drawings, and resubmit new samples for review and approval. CONTRACTOR shall direct specific attention in writing to revisions other than the corrections called for by ENGINEER or OWNER on previous submittals. CONTRACTOR'S stamp of approval on any shop drawing or sample shall constitute a representation to OWNER and ENGINEER that CONTRACTOR has either determined and verified all quantities, dimensions, field construction criteria, materials catalog numbers, and similar data, or assumes full responsibility for doing so, and that CONTRACTOR has reviewed or coordinated each Shop Drawing or sample with the requirements of the Work and the Contract Documents. 6.35 Where a Shop Drawing or sample is required by the specifications, no related Work shall be commenced until the submittal has been reviewed and approved by ENGINEER as to Shop Drawing and ENGINEER and OWNER as to samples 6.36 ENGINEER'S review and approval of Shop Drawings or ENGINEER’S and OWNER’S review and approval samples shall not relieve CONTRACTOR from responsibility for any deviations from the Contract Documents unless CONTRACTOR has, in writing, called ENGINEER'S and /or OWNER’s attention to such deviation at the time of submission, and ENGINEER with prior approval of OWNER has given written concurrence and approval to the specific deviation, nor shall any concurrence or approval by ENGINEER or OWNER relive CONTRACTOR from responsibility for errors or omissions in the Shop Drawings. CONTINUING THE WORK: 6.37 CONTRACTOR shall carry on the Work and maintain the progress schedule during all disputes or disagreements with OWNER. No Work shall be delayed or postponed pending resolution of any disputes or disagreements, except as CONTRACTOR and OWNER may otherwise agree in writing. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 17 INDEMNIFICATION: 6.38 To the fullest extent permitted by law, CONTRACTOR shall indemnify and hold harmless OWNER and ENGINEER, and their officials, agents and employees, from and against any and all claims, damages, liabilities, losses, cleanup or damages derived from pollutants, and expenses including, but not limited to, attorney’s fees and costs arising out of, or resulting from, the performance or non-performance of the Work, and including, but not limited to, claims, damages, liabilities, losses, or expenses attributable to bodily injury, sickness, disease, or death, or to injury to or destruction of tangible property including the loss of use resulting therefrom or is caused, in whole or in part, by any negligent act or omission of CONTRACTOR, any Subcontractor, anyone directly or indirectly employed by any of them, or anyone for whose acts any of them may be liable. Nothing in the contract shall be interpreted that the OWNER waives its sovereign immunity granted under Colorado Governmental Immunity Act if applicable or other applicable law. 6.39 In any and all claims against OWNER or ENGINEER, or any of their agents or employees, by any employee of CONTRACTOR, any Subcontractor, anyone directly or indirectly employed by any of them, or anyone for whose acts any of them may be liable, the indemnification obligation under paragraph 6.38 shall not be limited in any way by any limitation on the amount or type of damages, compensation, or benefits payable by or for CONTRACTOR or any Subcontractor under worker’s compensation acts, disability benefit acts, or other employee benefit acts. 6.40 The obligations of CONTRACTOR under paragraph 6.38 shall not extend to the liability of ENGINEER, his agents, or employees arising out of the preparation or approval of maps, drawings, opinions, reports, surveys, change orders, designs, or specifications. ARTICLE 7 – WORK BY OTHERS 7.1 OWNER may perform additional Work related to the Project by himself, or have additional work performed by utility service companies, or let other direct contracts therefore which shall contain general conditions similar to these. CONTRACTOR shall afford the utility service companies and the other contractors who are parties to such direct contracts (or OWNER, if OWNER is performing the additional work with OWNER'S employees) reasonable opportunity for the introduction and storage of materials and equipment, and the execution of work, and shall properly connect and coordinate his work with theirs. 7.2 If any part of CONTRACTOR'S Work depends, for proper execution or results, upon the Work of any such other contractor or utility service company (or OWNER), CONTRACTOR shall inspect and promptly report to ENGINEER and OWNER in writing any patent or apparent defects or deficiencies in such Work that render it unsuitable for such proper execution and results. CONTRACTOR'S failure to so report shall constitute an acceptance of the other Work as fit and proper for integration with CONTRACTOR'S Work, except for latent or non-apparent defects and deficiencies in the other Work. 7.3 CONTRACTOR shall do all cutting, fitting, and patching of his Work that may be required to make its several parts come together properly and integrate with such other Work. CONTRACTOR shall not endanger any work of others by cutting, excavating, or otherwise altering their work, and will only cut or alter their work with the written consent of ENGINEER and OWNER and the others whose work will be affected. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 18 7.4 If the performance of additional work by other contractors or utility service companies or OWNER was not noted in the Contract Documents, written notice thereof shall be given to CONTRACTOR prior to starting any such additional work. If CONTRACTOR believes that the performance of such additional work by OWNER or others involves additional expense to CONTRACTOR, or requires an extension of the Contract Time, CONTRACTOR may make a claim therefore as provided in Articles 11 and 12. ARTICLE 8 – OWNER’S RESPONSIBILITIES 8.1 OWNER shall issue communications to CONTRACTOR or through ENGINEER. 8.2 In case of termination of the employment of ENGINEER, OWNER shall appoint an ENGINEER whose status under the Contract Documents shall be that of the former ENGINEER. 8.3 OWNER and all of its employees and agents shall have the right to full access and use of the Project site. Such use shall not constitute acceptance of the Work or any part thereof, or waive any of OWNER’S rights or remedies under the Contract Documents. ARTICLE 9 – ENGINEER’S STATUS DURING CONSTRUCTION OWNER’S REPRESENTATIVE: 9.1 The duties and responsibilities and the limitations of authority of ENGINEER as an OWNER'S representative during construction are set forth in the Contract Documents, and shall not be extended without written consent of OWNER and ENGINEER. Notwithstanding anything to the contrary herein, in all instances in the Contract Documents where ENGINEER has the authority to make decisions concerning quality of and acceptance of the Work performed by CONTRACTOR the ENGINEER shall first discuss such decision and proposed acceptance with OWNER and obtain its approval prior to communicating with the CONTRACTOR. Further, in all instances in the Contract Documents where ENGINEER has the authority to make a decision that impacts the Project budget or Contract Price or payment to the CONTRACTOR, then ENGINEER shall first discuss the payment or costs with OWNER and obtain its approval prior to approving any payment, additive or deductive Work. This paragraph is not intended as and shall not be a waiver of ENGINEER’S responsibility for oversight of the Work. VISITS TO SITE: 9.2 ENGINEER will make visits to the site at intervals appropriate to the various stages of construction to observe the progress and quality of the executed Work and to determine, in general, if the Work is proceeding in accordance with the Contract Documents. ENGINEER will not be required to make exhaustive or continuous on-site inspections to check the quality or quantity of the Work. ENGINEER'S efforts will be directed toward providing for OWNER a greater degree of confidence that the completed Work will conform to the Contract Documents. On the basis of such visits and on-site observations, as an experienced and qualified design professional, ENGINEER will keep OWNER informed of the progress of the Work, and will endeavor to guard OWNER against defects and deficiencies in the Work. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 19 CLARIFICATIONS AND INTERPRETATIONS: 9.3 ENGINEER will issue, with reasonable promptness, such written clarifications or interpretations of the Contract Documents (in the form of drawings or otherwise) as ENGINEER and OWNER may determine necessary, which shall be consistent with, or reasonably inferable from, the overall intent of the Contract Documents. If CONTRACTOR believes that a written clarification or interpretation justifies an increase in the Contract Price or Contract Time, CONTRACTOR may make a claim therefore, as provided in Article 11 or Article 12. REJECTING DEFECTIVE WORK: 9.4 ENGINEER after conferring and receiving approval of OWNER will have authority to disapprove or reject Work which is defective, and will also have authority to require special inspection or testing of the Work as fabricated, installed, or completed. SHOP DRAWINGS, CHANGE ORDERS, AND PAYMENTS: 9.5 In connection with ENGINEER'S responsibility for Shop Drawings and samples, see paragraphs 6.31 through 6.37 inclusive. 9.6 In connection with ENGINEER'S responsibilities as to Change Orders see Articles 10, 11, and 12. 9.7 In connection with ENGINEER'S responsibilities in respect to applications for payment, etc., see Article 14. PROJECT REPRESENTATION: 9.8 Intentionally Omitted. DECISIONS ON DISAGREEMENTS: 9.9 ENGINEER will be the initial interpreter of the requirements of the Contract Documents concerning the acceptability of the Work thereunder. Claims, disputes, and other matters relating to the acceptability of the Work, or the interpretation of the requirements of the Contract Documents pertaining to the execution and progress of the Work, shall be referred initially to ENGINEER in writing with a request for a formal decision which ENGINEER and OWNER will together render in writing within a reasonable time. The final decision concerning any claim, dispute or other matter relating to acceptability of the Work or interpretation of the requirements of the Contract Documents pertaining to the execution and progress of the Work shall be OWNER’s. LIMITATIONS ON ENGINEER'S RESPONSIBILITIES: 9.10 Neither ENGINEER'S or OWNER’s authority to act under this Article 9, or elsewhere in the Contract Documents, nor any decision made by ENGINEER or OWNER in good faith either to exercise or not exercise such authority shall give rise to any duty or responsibility of ENGINEER or OWNER to CONTRACTOR, any Subcontractor, any manufacturer, fabricator, supplier, or distributor, or any of their agents or employees, or any other person performing any of the Work. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 20 9.11 Whenever, in the Contract Documents, the terms “as ordered”, “as directed”, “as required”, “as allowed”, or terms of like effect or import are used, or the adjectives “reasonable”, “suitable”, “acceptable”, “proper”, or “satisfactory”, or adjectives of like effect or import are used to describe requirement, direction, review, or judgment of ENGINEER as to the Work, it is intended that such requirement direction, review, or judgment will be solely to evaluate the Work for compliance with the Contract Documents (unless there is a specific statement indicating otherwise). The use of any such term or adjective never indicates that ENGINEER shall have authority to supervise or direct performance of the Work, or authority to undertake responsibility contrary to the provisions of paragraphs 9.12 or 9.13. 9.12 ENGINEER and OWNER will not be responsible for CONTRACTOR'S means, methods, techniques, sequences or procedures of construction, or the safety precautions and programs incident thereto, and ENGINEER and OWNER will not be responsible for CONTRACTOR'S failure to perform the Work in accordance with the Contract Documents. 9.13 ENGINEER and OWNER will not be responsible for the acts or omissions of CONTRACTOR, or of any Subcontractor, or of the agents or employees of any CONTRACTOR or Subcontractor, or of any other persons at the site or otherwise performing any of the Work. ARTICLE 10 – CHANGES IN THE WORK 10.1 Without invalidating the Agreement, OWNER may, at any time or from time to time, order additions, deletions, or revisions in the Work; these will be authorized by written change orders. Upon receipt of a change order, CONTRACTOR shall proceed with the Work involved. All such Work shall be executed under the applicable conditions of the Contract Documents. If any change order causes an increase or decrease in the Contract Price, or an extension or shortening of the Contract Time, an equitable adjustment will be made as provided in Article 11 or Article 12 on the basis of a claim made by either party. 10.2 ENGINEER with approval of OWNER may authorize minor changes in the Work, not involving an adjustment in the Contract Price or the Contract Time, which are consistent with the overall intent of the Contract Documents. These may be accomplished by a field order, and shall be binding on OWNER, and also on CONTRACTOR who shall perform the change promptly. If CONTRACTOR believes that a field order justifies an increase in the Contract Price or Contract Time, CONTRACTOR may make a claim therefore as provided in Article 11 or Article 12. 10.3 Additional Work performed without authorization of a change order will not entitle CONTRACTOR to an increase in the Contract Price, or an extension of the Contract Time, except in the case of an emergency as provided in paragraph 6.30, and except as provided in paragraph 13.9. 10.4 OWNER may execute appropriate change orders prepared by ENGINEER covering changes in the Work which are required by OWNER, or required because of unforeseen physical conditions or emergencies, or because of uncovering Work found not to be defective, or as provided in paragraphs 11.10 or 11.11. 10.5 Intentionally Omitted. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 21 ARTICLE 11 – CHANGE OF CONTRACT PRICE 11.1 The Contract Price constitutes the total compensation (subject to authorized adjustments) payable to CONTRACTOR for performing the Work. All duties, responsibilities, and obligations assigned to or undertaken by CONTRACTOR shall be at his expense without change in the Contract Price. 11.2 The Contract Price may only be changed by a Change Order. Any claim for an increase in the Contract Price shall be based on written notice delivered to OWNER and ENGINEER within seven days of the occurrence of the event giving rise to the claim. Any change in the Contract Price resulting from any such claim shall first be approved by ENGINEER and OWNER before being incorporated in a change order. 11.3 No change orders or other form of order or directive which requires additional compensable Work to be performed may be issued or be effective unless accompanied by a written assurance to the CONTRACTOR that lawful appropriations to cover the costs of the additional Work have been made. 11.4 The value of any Work covered by a change order, or of any claim for an increase or decrease in the Contract Price, shall be determined in one of the following ways: 11.4.1 Where the Work involved is covered by unit prices contained in the Contract Documents, by application of unit prices to the quantities of the items involved (subject to the provisions of paragraph 11.10). 11.4.2 By mutual acceptance of a lump sum. 11.4.3 On the basis of the Cost of the Work (determined as provided in paragraphs 11.5 and 11.6) plus a Contractor’s Fee for overhead and profit as provided in paragraph 11.7. 11.4.4 Regardless of method for determining the value of any Work covered by a change order, the CONTRACTOR shall provide OWNER with written documentation concerning the claim, including but not limited to the specific reasons for the claim. 11.5 The term “Cost of the Work” means the sum of any and all costs necessarily incurred and paid by CONTRACTOR in the proper performance of the Work. Except as otherwise may be agreed to in writing by OWNER, such costs shall be in amounts no higher than those prevailing in the locality for the Project, shall include only the following items, and shall not include any of the costs itemized in paragraph 11.6: 11.5.1 Payroll costs for employees in the direct employ of CONTRACTOR on-site in the performance of the Work under schedules of job classifications agreed upon by OWNER and CONTRACTOR. Payroll costs for employees not employed full time on the Work shall be apportioned on the basis of their time spent on the Work. Payroll costs shall include, but not be limited to, salaries and wages, plus the cost of fringe benefits which shall include social security contributions, unemployment, excise and payroll taxes, worker’s compensation, health and retirement benefits, bonuses, sick leave, vacation and holiday pay applicable thereto. Such employees shall include superintendents and foremen at the site. The expenses of performing Work after regular working hours, or on Sunday or legal holidays, shall be included in the above only to the extent authorized by OWNER. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 22 11.5.2 Cost of all materials and equipment furnished and incorporated in the Work, including costs of transportation and storage thereof, and manufacturers’ field services required in connection therewith. All cash discounts shall accrue to OWNER. All trade discounts, rebates and refunds, and all returns from sale of surplus materials and equipment shall accrue to OWNER, and CONTRACTOR shall make provisions so that they may be obtained. 11.5.3 Payments made by CONTRACTOR to the Subcontractors for Work performed by Subcontractors. If required by OWNER, CONTRACTOR shall obtain competitive bids from Subcontractors acceptable to CONTRACTOR, and shall deliver such bids to OWNER, who will then determine, with the advice of ENGINEER, which bids will be accepted. If a subcontract provides that the Subcontractor is to be paid on the basis of Cost of the Work, the Subcontractor’s Cost of the Work plus a fee shall be determined in the same manner as CONTRACTOR'S Cost of the Work. All Subcontracts shall be subject to the other provisions of the Contract Documents insofar as applicable. 11.5.4 Supplemental costs including the following: 11.5.4.1 The proportion of necessary transportation, travel, and subsistence expenses of CONTRACTOR'S employees incurred in discharge of duties connected with the Work. 11.5.4.2 Cost, including transportation and maintenance, of all materials, supplies, equipment, machines, appliances, office and temporary facilities at the site, and hand tools not owned by the workmen, which are consumed in the performance of the Work, and cost less market value of such items used but not consumed which remain the property of CONTRACTOR. 11.5.4.3 Rentals of all construction equipment and machinery, and the parts thereof, whether rented from CONTRACTOR or others in accordance with rental agreements approved by OWNER with the advice of ENGINEER, and the costs of transportation, loading, unloading, installation, dismantling and removal thereof, all in accordance with terms of said rental agreements. The rental of any such equipment, machinery or parts shall cease when the use thereof is no longer necessary for the Work. 11.5.4.4 Intentionally Omitted. 11.5.4.5 Deposits lost for causes other than CONTRACTOR'S negligence, royalty payments, and fees for permits and licenses. 11.5.4.6 Intentionally Omitted. 11.5.4.7 Intentionally Omitted. 11.5.4.8 Intentionally Omitted. 11.5.4.9 Cost of premiums for additional bonds and insurance required because of changes in the Work. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 23 11.6 The term “Cost of the Work” shall not include any of the following: 11.6.1 Payroll costs and other compensation of CONTRACTOR'S officers, executives, principals (of partnership and sole proprietorship), general managers, ENGINEER's, ENGINEERs, estimators, lawyers, auditors, accountants, purchasing and contracting agents, expediters, timekeepers, clerks, and other personnel employed by CONTRACTOR whether at the site or in his principal or a branch office for general administration of the Work, and not specifically included in the agreed upon schedule of job classifications referred to in subparagraph 11.5.1. all of which are considered to be administrative costs covered by the Contractor’s Fee. 11.6.2 Expenses of CONTRACTOR'S principal and branch office, other than CONTRACTOR'S office at the site. 11.6.3 Any part of CONTRACTOR'S capital expenses including interest on CONTRACTOR'S capital employed for the Work, and charges against CONTRACTOR for delinquent payments. 11.6.4 Cost of premiums for all bonds and for all insurance whether or not CONTRACTOR is required by the Contract Documents to purchase and maintain the same (except for additional bonds and insurance required because of changes in the Work). 11.6.5 Costs due to the negligent performance or non-performance of CONTRACTOR, any Subcontractor, or anyone directly or indirectly employed by any of them, or for whose acts any of them may be liable, including, but not limited to, the correction of defective Work, disposal of materials or equipment wrongly supplied, and making good any damage to property. 11.6.6 Other overhead or general expense costs of any kind, and the costs of any item not specifically and expressly included in paragraph 11.5. CONTRACTOR’S FEE: 11.7 The Contractor’s Fee allowed to CONTRACTOR for overhead and profit shall be determined as follows: 11.7.1 A mutually acceptable fixed fee as provided in the SUPPLEMENTAL UNIT PRICING for Construction Manager/General Contractor Overhead and Profit Fee. 11.7.2. No fee shall be payable on the basis of costs itemized under paragraphs 11.5.4 and 11.6. 11.8 The amount of credit to be allowed by CONTRACTOR to OWNER for any such change which results in a net decrease in cost will be the amount of the actual net decrease. When both additions and credits are involved in any one change, the combined adjustment to overhead and profit shall be figured on the basis of the net increase or decrease in allowable costs, if any. ADJUSTMENT OF UNIT QUANTITIES: 11.9 Whenever the cost of any Work is to be determined based upon unit price, CONTRACTOR will submit, in form acceptable to ENGINEER and OWNER, an itemized cost breakdown together with supporting data. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 24 11.10 Where the quantity of Work with respect to any item that is covered by a unit price differs materially and significantly from the quantity of such Work indicated in the Contract Documents, an appropriate change order (additive or deductive) may be issued on recommendation of ENGINEER with written approval of OWNER. In no event will the unit price bid by CONTRACTOR be modified, but the quantity of any item may be increased or decreased as set forth herein. Notwithstanding the foregoing, in no event will the change modify the not to exceed the Contract Price or otherwise be modified without a change order approved by OWNER in writing. CASH ALLOWANCES: 11.11 It is understood that CONTRACTOR has included in the Contract Price all allowances so named in the Contract Documents, and shall cause the Work so covered to be done by such Subcontractors, manufacturers, fabricators, suppliers, or distributors, and for such sums within the limit of the allowances as may be acceptable to ENGINEER and OWNER. Upon final payment, the Contract Price shall be adjusted as required, and an appropriate change order issued. CONTRACTOR agrees that the original Contract Price includes such sums as CONTRACTOR deems proper for costs and profit on account of cash allowances. No demand for additional cost or profit in connection therewith will be valid. ARTICLE 12 – CHANGE OF THE CONTRACT TIME 12.1 The Contract Time may only be changed by a change order. Any claim for an extension in the Contract Time shall be based on written notice delivered to OWNER and ENGINEER within seven days of the occurrence of the event giving rise to the claim. Any change in the Contract Time resulting from any such claim shall be incorporated in a change order. 12.2 All time limits stated in the Contract Documents are of the essence of the Agreement. The provisions of Articles 11 and 12 are CONTRACTOR'S sole remedies for delay by any cause whatsoever, including acts of OWNER. ARTICLE 13 – WARRANTY AND GUARANTEE; TESTS AND INSPECTION; CORRECTION, REMOVAL OR ACCEPTANCE OF DEFECTIVE WORK WARRANTY AND GUARANTEE: 13.1 CONTRACTOR warrants and guarantees to OWNER and ENGINEER that all Work will be in accordance with the Contract Documents and will not be defective. Prompt notice of all defects shall be given to CONTRACTOR. All defective Work, whether or not in place, may be rejected, corrected, or accepted as provided in this Article 13. Further, CONTRACTOR warrants to OWNER that (i) materials and equipment furnished under the Contract Documents shall be of highest quality and new unless otherwise required or permitted by the Contract Documents; (ii) the Work shall be free from defects and deficiencies; (iii) the Work shall conform to the requirements of the Contract Documents, applicable laws and applicable permits; and (iv) the Work shall be performed in a good and workman like manner. All guarantees and warranties of equipment or materials furnished to CONTRACTOR or any Subcontractor(s) by any manufacturer or supplier shall be for the benefit of OWNER. CONTRACTOR does hereby covenant, warrant and agree that it shall repair or replace any and all of the Work, together with other Work which may be displaced by such repair or replacement, without any cost to OWNER DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 25 for a period of two years following the date of Substantial Completion of the Work. This obligation shall survive both final payment for the Work or designated portion thereof and termination of this Agreement. ACCESS TO WORK: 13.2 OWNER, ENGINEER, ENGINEER'S representatives, other representatives of OWNER, testing agencies, and governmental agencies with jurisdictional interests will have access to the Work at reasonable times for their observation, inspection and testing. CONTRACTOR shall provide proper and safe conditions for such access. TESTS AND INSPECTIONS: 13.3 CONTRACTOR shall give ENGINEER and OWNER timely notice of readiness of Work for all required inspections, tests or approvals. 13.4 If any law, ordinance, rule, regulation, code, or order of any public body having jurisdiction requires any Work (or part thereof) to specifically be inspected, tested, or approved, CONTRACTOR shall assume full responsibility therefore, pay all costs in connection therewith, and furnish ENGINEER and OWNER the required certificates of inspection, testing, or approval. CONTRACTOR shall also be responsible for and shall pay all costs in connection with any inspection or testing required in connection with OWNER'S or ENGINEER'S acceptance of a manufacturer, fabricator, supplier or distributor of materials or equipment proposed to be incorporated in the Work, or of materials or equipment submitted for approval prior to CONTRACTOR'S purchase thereof for incorporation of the Work. The cost of all other inspections, tests, and approvals required by the Contract Documents shall be paid by OWNER (unless otherwise specified). 13.5 Any inspections, tests, or approvals, other than those required by law, ordinance, rule, regulation, code, or order of any public body having jurisdiction, shall be performed by organizations acceptable to OWNER and CONTRACTOR (or by ENGINEER if so specified). 13.6 If any Work that is to be inspected, tested, or approved is covered without written concurrence of ENGINEER and OWNER, it must, if requested by ENGINEER or OWNER, be uncovered for observation. Such uncovering shall be at CONTRACTOR'S expense, unless CONTRACTOR has given ENGINEER and OWNER timely notice of CONTRACTOR'S intention to cover such Work and ENGINEER or OWNER has not acted with reasonable promptness in response to such notice. 13.7 Neither observations by ENGINEER or OWNER nor inspections, tests, or approvals by others shall relieve CONTRACTOR from his obligations to perform the Work in accordance with the Contract Documents. UNCOVERING WORK: 13.8 If any Work is covered contrary to the written request of ENGINEER or OWNER, it must, if requested by ENGINEER or OWNER, be uncovered for ENGINEER’S and OWNER’s observation and replaced at CONTRACTOR'S expense. 13.9 If ENGINEER or OWNER considers it necessary or advisable that covered Work be observed by ENGINEER or OWNER, or inspected or tested by others, CONTRACTOR, at ENGINEER'S or DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 26 OWNER’s request, shall uncover, expose, or otherwise make available for observation, inspection, or testing as ENGINEER or OWNER may require, that portion of the Work in question, furnish all necessary labor, material, and equipment. If it is found that such Work is defective, CONTRACTOR shall bear all the expenses of such uncovering, exposure, observation, inspection, and testing of satisfactory reconstruction, including compensation for additional professional services, and an appropriate deductive change order shall be issued. If, however, such Work is not found to be defective, CONTRACTOR shall be allowed an increase in the Contract Price, or an extension of the Contract Time, or both, directly attributable to such uncovering, exposure, observation, inspection, testing, and reconstruction. OWNER MAY STOP THE WORK: 13.10 If the Work is defective, or CONTRACTOR fails to supply sufficient skilled workmen or suitable materials or equipment, OWNER may order CONTRACTOR to stop the Work, or any portion thereof, until the cause for such order has been eliminated; however, this right of OWNER to stop the Work shall not give rise to any duty on the part of OWNER to exercise this right for the benefit of CONTRACTOR or any other party. CORRECTION OR REMOVAL OF DEFECTIVE WORK: 13.11 If required by ENGINEER or OWNER, CONTRACTOR shall promptly, without cost to OWNER and as specified by ENGINEER or OWNER, either correct any defective Work, whether or not fabricated, installed, or completed, or, if the Work has been rejected by ENGINEER or OWNER, remove it from the site and replace it with non-defective Work in a manner acceptable to the ENGINEER and OWNER. TWO YEAR CORRECTION PERIOD: 13.12 If, within two years after the date of Substantial Completion, or such longer period of time as may be prescribed by law, or by the terms of any applicable special guarantee required by the Contract Documents, or by any other specific provision of the Contract Documents, any Work is found to be defective, CONTRACTOR shall promptly, without cost to OWNER, and in accordance with OWNER'S written instructions, either correct such defective Work, or, if it has been rejected by OWNER, remove it from the site, and replace it with non-defective Work. If CONTRACTOR does not promptly comply with the terms of such instructions, or in an emergency where delay would cause serious risk of loss or damage, OWNER may have the defective Work corrected or the rejected Work removed and replaced, and all direct and indirect costs of such removal and replacement, including compensation for additional professional services, shall be paid by CONTRACTOR. ACCEPTANCE OF DEFECTIVE WORK: 13.13 If, instead of requiring correction or removal and replacement of defective Work, OWNER (and prior to ENGINEER'S recommendation of final payment) prefers to accept it, OWNER may do so. In such case, if acceptance occurs prior to ENGINEER'S recommendation of final payment, a change order shall be issued incorporating the necessary revisions in the Contract Price; or, if the acceptance occurs after such recommendation, an appropriate amount shall be paid by CONTRACTOR to OWNER. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 27 OWNER MAY CORRECT DEFECTIVE WORK: 13.14 If CONTRACTOR fails, within a reasonable time after written notice of ENGINEER and OWNER, to proceed to correct defective Work, or to remove and replace rejected Work as required by ENGINEER or OWNER in accordance with paragraph 13.11, or if CONTRACTOR fails to perform the Work in accordance with the Contract Documents (including any requirements of the progress schedule), OWNER may, after seven days written notice to CONTRACTOR, correct and remedy any such deficiency. In exercising his rights under this paragraph OWNER shall proceed expeditiously. To the extent necessary to complete corrective and remedial action, OWNER may exclude CONTRACTOR from all part of the site, take possession of all or part of the Work, and suspend CONTRACTOR'S services related thereto, take possession of CONTRACTOR'S tools, appliances, construction equipment, and machinery at the site, and incorporate in the Work all materials and equipment stored at the site, or for which OWNER has paid CONTRACTOR, but which are stored elsewhere. CONTRACTOR shall allow OWNER, OWNER'S representatives, agents, and employees such access to the site as may be necessary to enable OWNER to exercise his rights under this paragraph. All direct and indirect costs of OWNER in exercising such rights shall be charged against CONTRACTOR in an amount verified by ENGINEER, and a change order shall be issued incorporating the necessary revisions in the Contract Documents and a reduction in the Contract Price. Such direct and indirect costs shall include, in particular but without limitation, compensation for additional professional services required, and all costs of repair and replacement of work of others destroyed or damaged by correction, removal, or replacement of CONTRACTOR'S defective Work. CONTRACTOR shall not be allowed an extension of the Contract Time because of any delay in performance of the Work attributable to the exercise by OWNER of OWNER'S rights hereunder. ARTICLE 14 – PAYMENTS TO CONTRACTOR AND COMPLETION SCHEDULES: 14.1 At least ten days prior to submitting the first application for a progress payment, CONTRACTOR shall (except as otherwise specified in the general requirements) submit to ENGINEER and OWNER a progress schedule, a final schedule of Shop Drawing submissions, and, where applicable, a schedule of values of the Work. These schedules shall be satisfactory in form and substance to ENGINEER and OWNER. The schedule of values shall include quantities and unit prices aggregating the Contract Price, and shall subdivide the Work into component parts in sufficient detail to serve as the basis for progress payments during construction. Upon acceptance of the schedule of values by ENGINEER and OWNER, it shall be incorporated into a form of application for payment acceptable to ENGINEER and OWNER. APPLICATION FOR PROGRESS PAYMENT: 14.2 At least ten days before each progress payment falls due (but not more often than once a month), CONTRACTOR shall submit to ENGINEER and OWNER for review an application for payment filled out and signed by CONTRACTOR covering the Work completed as of the date of the application, and accompanied by such supporting documentation as is required by the Contract Documents, and also as ENGINEER or OWNER may reasonably require. If payment is requested on the basis of materials and equipment not incorporated in the Work, but delivered and suitably stored at the site or at another location agreed to in writing, the application for payment shall also be accompanied by such data, satisfactory to OWNER, as will establish OWNER'S title DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 28 to the material and equipment, and protect OWNER'S interest therein, including applicable insurance. Each subsequent application for payment shall include an affidavit of CONTRACTOR stating that all previous progress payments received on account of the Work have been applied to discharge in full all of CONTRACTOR'S obligations reflected in prior applications for payment. The amount of retainage with respect to progress payments will be as stipulated in the Agreement. CONTRACTOR'S WARRANTY OF TITLE: 14.3 CONTRACTOR warrants and guarantees that title to all Work, materials, and equipment covered by any application for payment, whether incorporated in the Project or not, will pass to OWNER at the time of payment free and clear of all liens, claims, security interests, and encumbrances (hereafter in these General Conditions referred to as “Liens”). REVIEW OF APPLICATIONS FOR PROGRESS PAYMENT: 14.4 ENGINEER will, within ten days after receipt of each application for payment, either indicate in writing a recommendation of payment and present the application to OWNER, or return the application to CONTRACTOR indicating in writing ENGINEER'S reasons for refusing to recommend payment. In the latter case, CONTRACTOR may make the necessary corrections and resubmit the application. OWNER shall, within twenty days of presentation to him of the application for payment with ENGINEER'S recommendation, pay CONTRACTOR the amount recommended. 14.5 ENGINEER'S recommendation of any payment requested in an application for payment will constitute a representation by ENGINEER to OWNER that, based on ENGINEER'S on-site observations of the Work in progress as an experienced and qualified design professional, and on ENGINEER'S review of the application for payment, and the accompanying data and schedules, the Work has progressed to the point indicated; that, to the best of ENGINEER'S knowledge, information, and belief, the quality of the Work is in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning Project upon substantial completion, and to the results of any subsequent tests called for in the Contract Documents and any qualifications stated in the recommendation); and, that CONTRACTOR is entitled to payment of the amount recommended. However, by recommending any such payment, ENGINEER will not thereby be deemed to have represented that exhaustive or continuous on-site inspections have been made to check the quality or the quantity of Work, or that the means, methods, techniques, sequences, and procedures of construction have been reviewed, or that any examination has been made to ascertain how or for what purpose CONTRACTOR has used the monies paid or to be paid to CONTRACTOR on account of the Contract Price, or that title to any Work, materials, or equipment has passed to OWNER free and clear of any Liens. 14.6 ENGINEER'S recommendation of final payment will constitute an additional representation by ENGINEER to OWNER that the conditions precedent to CONTRACTOR'S being entitled to final payment as set forth in paragraph 14.13 have been fulfilled. 14.7 ENGINEER may refuse to recommend the whole, or any part of any payment if, in his opinion, it would be incorrect to make such representations to OWNER. He may also refuse to recommend any such payment, or, because of subsequently discovered evidence, or the results of subsequent inspections or tests, nullify any such payment previously recommended to such extent as may be necessary in ENGINEER'S opinion to protect OWNER from loss because: DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 29 14.7.1 the work is defective, or completed Work has been damaged requiring correction or replacement, 14.7.2 written claims have been made against OWNER, or liens have been filed in connection with the Work, 14.7.3 the Contract Price has been reduced because of Modifications, 14.7.4 OWNER has been required to correct defective Work, or complete the Work in accordance with paragraph 13.14, 14.7.5 of CONTRACTOR'S unsatisfactory prosecution of the Work in accordance with the Contract Documents, or 14.7.6 CONTRACTOR'S failure to make payment to Subcontractors, or for labor, materials, or equipment. SUBSTANTIAL COMPLETION: 14.8 When CONTRACTOR considers the entire Work ready for its intended use, CONTRACTOR shall, in writing to OWNER and ENGINEER, certify that the entire Work is substantially complete, and request that ENGINEER issue a certificate of substantial completion. Within a reasonable time thereafter, OWNER, CONTRACTOR, and ENGINEER shall make an inspection of the Work to determine the status of completion. If ENGINEER after conferring with OWNER does not consider the Work substantially complete, ENGINEER will notify CONTRACTOR in writing giving his reasons therefor. If ENGINEER after conferring with OWNER considers the Work substantially complete, ENGINEER will prepare and deliver to OWNER a tentative certificate of substantial completion which shall fix the date of substantial completion. There shall be attached to the certificate a tentative list of items to be completed or corrected before final payment. OWNER shall have seven days after receipt of the tentative certificate during which he may make written objection to ENGINEER as to any provisions of the certificate or attached list. If, after considering such objections, ENGINEER concludes that the Work is not substantially complete, ENGINEER will, within fourteen days after submission of the tentative certificate to OWNER, notify CONTRACTOR in writing stating his reasons therefor. If, after consideration of OWNER’S objections, ENGINEER considers the Work substantially complete, ENGINEER will, within said fourteen days, execute and deliver to OWNER and CONTRACTOR a definitive certificate of substantial completion (with a revised tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as he believes justified after consideration of any objections from OWNER. At the time of delivery of tentative certificate of substantial completion, OWNER and CONTRACTOR will mutually agree upon the division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, heat, utilities, and insurance. 14.9 OWNER shall have the right to exclude CONTRACTOR from the Work after the date of substantial completion, but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 30 PARTIAL UTILIZATION: 14.10 Use by OWNER of completed portions of the Work may be accomplished prior to substantial completion of all the Work subject to the following: 14.10.1 OWNER, at any time, may request CONTRACTOR in writing to permit OWNER to use any part of the Work which OWNER believes to be substantially complete and which may be so used without significant interference with construction of the other parts of the Work. If CONTRACTOR agrees, CONTRACTOR will certify to OWNER and ENGINEER that said part of the Work is substantially complete, and request ENGINEER to issue a certificate of substantial completion for that part of the Work. Within a reasonable time thereafter, OWNER, CONTRACTOR, and ENGINEER shall make an inspection of that part of the Work to determine its status of completion. If ENGINEER after conferring with OWNER considers that part of the Work to be substantially complete, ENGINEER will execute, and deliver to OWNER and CONTRACTOR, a certificate to that effect, fixing the date of substantial completion as to that part of the Work, attaching thereto a tentative list of items to be completed or corrected before final payment. Prior to issuing a certificate of substantial completion as to part of the Work, ENGINEER after conferring with OWNER will deliver to OWNER and CONTRACTOR a written recommendation as to the division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, utilities, and insurance for that part of the Work which shall become binding upon OWNER and CONTRACTOR at the time of issuing the definitive certificate of substantial completion as to that part of the Work, unless OWNER and CONTRACTOR shall have otherwise agreed in writing. OWNER shall have the right to exclude CONTRACTOR from any part of the Work which ENGINEER has so certified to be substantially complete, but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. 14.10.2 In lieu of the issuance of a certificate of substantial completion as to part of the work, OWNER may take over operation of a facility constituting part of the Work, whether or not it is substantially complete, if such facility is functionally and separately usable; provided that prior to any such takeover, OWNER and CONTRACTOR have agreed as to the division of responsibilities between OWNER and CONTRACTOR for security, operation, safety, maintenance, correction period, heat, utilities, and insurance with respect to such facility. 14.10.3 No occupancy of part of the Work, or taking over of operations of a facility will be accomplished before the insurers providing the property insurance have acknowledged notice thereof and in writing effected any changes in coverage necessitated thereby. The insurers providing the property insurance shall consent by endorsement on the policy or policies, but the property insurance shall not be cancelled or permitted to lapse on account of any such partial use or occupancy. FINAL INSPECTION: 14.11 Upon written notice from CONTRACTOR that the Work is complete, ENGINEER will make a final inspection with OWNER and CONTRACTOR, and will notify CONTRACTOR in writing of all particulars in which this inspection reveals that the Work is incomplete or defective. CONTRACTOR shall immediately take such measures as are necessary to remedy such deficiencies. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 31 FINAL APPLICATION FOR PAYMENT: 14.12 After CONTRACTOR has completed all such corrections to the satisfaction of ENGINEER and OWNER, and delivered all maintenance and operating instructions, schedules, guarantees, bonds, warranties, certificates of inspection, marked-up record documents, three (3) complete bound sets of required operations and maintenance manuals and instructions, two (2) sets of as built drawings, to the extent not already furnished, one (1) copy of all corrected Shop Drawings, satisfactory evidence that all payroll, material bills and other indebtedness with the Work have been paid or otherwise satisfied, consent of surety to final payment and other documents, all as required by the Contract Documents, and after ENGINEER and OWNER has indicated that the Work is acceptable (subject to the provisions of paragraph 14.14), CONTRACTOR may make application for final payment following the procedure for progress payments. The final application for payment shall be accompanied by all documentation called for in the Contract Documents, and such other data and schedules as ENGINEER and OWNER may reasonably require. Payment shall be processed in accordance with C.R.S. §§ 24-91-103 and 38-26-107. Notwithstanding the foregoing, CONTRACTOR will provide complete and legally effective lien releases or waivers satisfactory to OWNER. In lieu thereof, and as approved by OWNER, CONTRACTOR may furnish receipts or releases in full; an affidavit of CONTRACTOR that the releases and receipts include all labor, services, material, and equipment for which lien could be filed, and that all payrolls, material, and equipment bills, and other indebtedness connected with the Work, for which OWNER or his property might in any way be responsible, have been paid or otherwise satisfied; and consent of the surety, if any, to final payment. If any Subcontractor, manufacturer, fabricator, supplier, or distributor fails to furnish a release or receipt in full, CONTRACTOR may furnish a bond or other collateral satisfactory to OWNER to indemnify OWNER. FINAL COMPLETION AND FINAL PAYMENT AND ACCEPTANCE: 14.13 If, after conferring with OWNER and on the basis of ENGINEER'S observation of the Work during construction and final inspection, and ENGINEER'S review of the final application for payment and accompanying documentation, all as required by Contract Documents, ENGINEER and OWNER are satisfied that the Work has been completed and CONTRACTOR has fulfilled all of his obligations under the Contract Documents, ENGINEER will, within ten days after receipt of the final application for payment, indicate in writing his recommendation of payment, and present the application to OWNER for payment. Thereupon, ENGINEER will give written notice to OWNER and CONTRACTOR that the Work is acceptable subject to the provisions of paragraph 14.15. Otherwise, ENGINEER will return the application to CONTRACTOR, indicating in writing the reasons for refusing to recommend final payment, in which case CONTRACTOR shall make the necessary corrections, and resubmit the application. If the application and accompanying documentation are appropriate as to form and substance, OWNER shall, after receipt thereof, pay CONTRACTOR in accordance with the payment procedures set forth in the Agreement, the amount recommended by ENGINEER. CONTRACTOR’S CONTINUING OBLIGATION: 14.14 CONTRACTOR'S obligation to perform and complete the Work in accordance with the Contract Documents shall be absolute. Neither recommendation of any progress or final payment by ENGINEER, nor the issuance of a certificate of substantial completion, nor any payment by DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 32 OWNER to CONTRACTOR under the Contract Documents, nor any use or occupancy of the Work or any part thereof by OWNER, nor any act of acceptance by OWNER, nor any failure to do so, nor the issuance of a notice of acceptability by ENGINEER pursuant to paragraph 14.13, nor any correction of defective Work by OWNER shall constitute an acceptance of Work not in accordance with the Contract documents or a release of CONTRACTOR'S obligation to perform the Work in accordance with the Contract Documents. WAIVER OF CLAIMS: 14.15 The making and acceptance of final payment shall constitute: 14.15.1 a waiver of all claims by OWNER against CONTRACTOR, except claims arising from unsettled liens, from defective Work appearing after final inspection pursuant to paragraph 14.11, or from failure to comply with the Contract Documents or the terms of any special guarantees specified therein; however, it shall not constitute a waiver by OWNER of any rights in respect of CONTRACTOR'S continuing obligations under the Contract Documents; and 14.15.2 a waiver of all claims by CONTRACTOR against OWNER other than those previously made in writing and still unsettled. ARTICLE 15 – SUSPENSION OF WORK AND TERMINATION OWNER MAY SUSPEND WORK: 15.1 OWNER may, at any time and without cause, suspend the Work, or any portion thereof, for a period of not more than ninety days, by notice in writing to CONTRACTOR and ENGINEER which shall fix the date on which Work shall be resumed. CONTRACTOR shall resume the Work on the date so fixed. CONTRACTOR may, at the OWNER'S sole discretion, be allowed an increase in the Contract Price, or an extension of the Contract Time, or both, directly attributable to any suspension, if he makes a claim therefor as provided in Articles 11 and 12. 15.2 Upon the occurrence of any one or more of the following events: 15.2.1 if CONTRACTOR is adjudged bankrupt or insolvent, 15.2.2 if CONTRACTOR makes a general assignment for the benefit of creditors, 15.2.3 if a trustee or receiver is appointed for CONTRACTOR or for any of CONTRACTOR'S property, 15.2.4 if CONTRACTOR files a petition to take advantage of any debtor’s act, or to reorganize under the bankruptcy or similar laws, 15.2.5 if CONTRACTOR repeatedly fails to supply sufficient skilled workmen, or suitable materials or equipment, 15.2.6 if CONTRACTOR repeatedly fails to make prompt payments to Subcontractors, or for labor, materials, or equipment, DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 33 15.2.7 if CONTRACTOR disregards laws, ordinances, rules, regulations, or orders of any public body having jurisdiction, 15.2.8 if CONTRACTOR disregards the authority of ENGINEER, or 15.2.9 if CONTRACTOR otherwise violates, in any substantial way, any provisions of the Contract Documents, OWNER may, after giving CONTRACTOR and his surety seven days written notice, terminate the services of CONTRACTOR, exclude CONTRACTOR from the site, and take possession of the Work and of all CONTRACTOR'S tools, appliances, construction equipment, and machinery at the site, and use the same to the full extent they could be used by CONTRACTOR (without liability to CONTRACTOR for trespass or conversion), incorporate in the Work all materials and equipment stored at the site, or for which OWNER has paid CONTRACTOR but which are stored elsewhere, and finish the Work as OWNER may deem expedient. In such case, CONTRACTOR shall not be entitled to receive any further payment until the Work is finished. If the unpaid balance of the Contract Price exceeds the direct and indirect costs of completing the Work, including compensation for additional professional services, such excess shall be paid to CONTRACTOR. If such costs exceed such unpaid balance, CONTRACTOR shall pay the difference to OWNER. Such costs incurred by OWNER shall be verified by ENGINEER and incorporated in a change order, but in finishing the Work, OWNER shall not be required to obtain the lowest figure for the Work performed. 15.3 Where CONTRACTOR'S services have been so terminated by OWNER, the termination shall not affect any rights of OWNER against CONTRACTOR then existing, or which may thereafter accrue. Any retention or payment of monies due CONTRACTOR by OWNER will not release CONTRACTOR from liability. 15.4 Upon seven days written notice to CONTRACTOR and ENGINEER, OWNER may, without cause and without prejudice to any other right or remedy, terminate the Agreement. In such case, CONTRACTOR shall be paid for all Work executed and expenses sustained through the date of termination. CONTRACTOR MAY STOP WORK OR TERMINATE: 15.5 If, through no act or fault of CONTRACTOR, the Work is suspended for a period of more than ninety days by OWNER, or under an order of court or other public authority, or ENGINEER fails to act on any application for payment within thirty days after it is submitted, or OWNER fails for thirty days to pay CONTRACTOR any sum finally determined to be due, then CONTRACTOR may, upon seven days written notice to OWNER and ENGINEER, terminate the Agreement and recover from OWNER payment for all Work executed through the date of termination. ARTICLE 16 – MISCELLANEOUS GIVING NOTICE: 16.1 Whenever any provision of the Contract Documents requires the giving of written notice, it shall be deemed to have been validly given if delivered in person to the individual, or to a member of the firm, or to an officer of the corporation for whom it is intended, or if delivered at or sent by DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D 34 registered or certified mail, postage prepaid, to the last business address known to the giver of the notice. COMPUTATION OF TIME: 16.2 When any period of time is referred to in the Contract Documents by days, it shall be calendar days and be computed to exclude the first and include the last day of such period. If the last day of any such period falls on a Saturday or Sunday, or on a day made a legal holiday by the law of the applicable jurisdiction, such day shall be omitted from the computation. GENERAL: 16.3 Should OWNER or CONTRACTOR suffer injury or damage to his person or property because of any error, omission or act of the other party or of any of the other party’s employees or agents, or others for whose acts the other party is legally liable, claim shall be made in writing to the other party within a reasonable time of the first observances of such injury or damage. 16.4 The duties and obligations imposed by these General Conditions and the rights and remedies available hereunder to the parties hereto, and, in particular, but without limitation, the warranties, guarantees, and obligations imposed upon CONTRACTOR by paragraphs 6.38, 13.1, 13.11, 13.14, 14.3, and 15.2, and all of the rights and remedies available to OWNER and ENGINEER thereunder, shall be in addition to, and shall not be construed in any way as a limitation of, any rights and remedies available to any or all of them which are otherwise imposed or available by law or contract, by special warranty or guarantee, or by other provisions of this paragraph shall be as effective as if repeated specifically in the Contract Documents in connection with each particular duty, obligations, right and remedy to which they apply. All representations, warranties, and guarantees made in the Contract Documents shall survive final payment and termination or completion of this Agreement.

This CQAQCP addresses the quality assurance of the construction and installation of environmental control systems at the Eagle Landfill, including earthen materials (low hydraulic conductivity soils and drainage materials) and man-made materials (geosynthetic clay liner, geomembranes and geotextiles). This CQAQCP is intended to be a "working" document; i.e., one that is updated to reflect changes in specific materials used, in installation practices, or in tests and test methods. The CQAQCP includes the construction information and procedures for the following systems at the Landfill: • Landfill floor and side slope compacted clay liner system. • Geomembrane and geotextile installation for the leachate sump. • Leachate drain system (from landfill to the leachate sump). • Leachate holding pond. • Final cover. • Surface water drainage. The scope of this CQAQCP includes the quality assurance applicable to these six landfill systems for the following: • Soil excavation and placement. • Manufacturing, fabricating, shipping, handling, and installation of the geosynthetic components. 1.1 CONSTRUCTION QUALITY ASSURANCE Construction quality assurance is defined as follows: Construction Quality Assurance (CQA) is a planned system of activities that provides the Owner and permitting agency assurance that the facility was constructed as specified in the design. Construction quality assurance includes inspections, verifications, audits, and evaluations of materials and workmanship necessary to determine and document the quality of the constructed facility. Construction quality assurance refers to measures taken by the CQA organization to assess if the Installer or Contractor is in compliance with the plans and specifications for a project. 1.2 GENERAL TESTING REQUIREMENTS This CQAQCP includes references to test procedures of the American Society for Testing and Materials (ASTM), American Concrete Institute (ACI), the National Sanitation Foundation Standard Number 54 Flexible Membrane Liners, and the Geosynthetics Research Institute (GRI). Unless indicated otherwise, tests will be performed in strict accordance with the referenced test procedure and the description included in this plan. Any deviations to test procedures specified in this plan must be approved, in writing, by the Construction Quality Assurance Engineer (CQAE).

The CQAE may consult the Design Engineer regarding design specifications and/or recommended changes; however, the Design Engineer has no direct responsibilities set forth in this plan. The Contractor (including any subcontractors that may be brought to the site) will report to the Owner/Operator and the CQAE for matters relating to the CQAQCP. For financial or other issues, the Contractor will report directly to the Owner/Operator. 1.4 MEETINGS There are two types of meetings which will be required for implementation of this Plan including pre-construction meetings and problem/deficiency meetings: A pre-construction meeting will be conducted immediately prior to any construction and will be attended by the Owner/Operator and the Contractor along with other appropriate parties such as the Soils Testing Laboratory, and the CQAE. The purpose of this meeting will be to review the project and the CQAQCP as it applies to environmental control system construction and familiarize all parties with their respective responsibilities and interactions. Problem/deficiency meetings will be conducted, as requested by the Owner/Operator or the CQAE, to work out problems which may arise with the construction or QA/QC testing. The meetings will be attended by appropriate parties. 1.5 DOCUMENTATION This section describes the types of documentation reports that must be completed by each party that has direct QA/QC responsibility for the landfill construction. The CQAE is responsible for construction documentation and will ensure that other parties to the construction will document their portions of the work. The documentation of construction quality assurance activities is the most effective method to ensure that the quality assurance requirements have been addressed and satisfied. The documentation process includes: • Recognition of construction tasks that should be documented. • Assignment of responsibilities for the observation, testing, and documentation of these tasks. • Completion of the required forms, data sheets, and reports to provide an accurate record of the work performed during construction. 1.5.1 Daily Construction Reports A construction report will be completed by the CQAE or the Soils Testing Laboratory each day that they perform work on the site. This summary report will provide a chronological record for identifying and recording other reports, data sheets, forms, and checklists. This report will contain, at a minimum, the following information to be filled out in ink and preferably pre-printed so that the required information is organized in an easily accessible manner: • Date, project name, location, and report preparer's name. The number and name of people on site under the direction of the preparer related to QA/QC tasks. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 5 • Data on weather conditions including temperature, humidity, wind direction and speed, cloud cover, and any precipitation events. • Contractor's or Installer's work force, equipment in use and idle, and materials delivered to or removed from the job site. • Chronological description of work in progress including any notices to, or requests from, the Contractor and/or the Installer. • Results of, or a clear reference to, where the results can be found for testing per- formed on site by personnel under the direction of the preparer. • Laboratory samples collected, marked, and sent to the outside testing laboratories will be clearly indicated in the daily report by direct inclusion or by reference to the document containing such information. Likewise, reference should be included for any test data submitted by any of the outside testing laboratories. • An accurate record of communications with other CQAQCP parties, or any other outside companies, regulatory agencies, or consultants regarding the day's construction activities or any project meetings that are held will be kept. • An accurate record of calibrations or standardizations performed on field testing equipment, including actions taken as a result of recalibrations, will also be kept. 1.5.2 Problem/Deficiency Identification and Corrective Action Reports Problem and/or deficiency and corrective action reports will be completed by the Soils Testing Laboratory and/or the CQAE when any construction material or activity is observed or tested and does not meet the requirements set forth in this plan. These reports are not necessary for a failing field test if corrective action is taken and retesting confirms acceptable properties. These reports should be cross-referenced to the forms, data sheets, checklists, and other reports that contain data or observations leading to the determination of a problem or deficiency. At a minimum, the Problem/Deficiency Identification and Corrective Action Reports will include the following information: • A detailed description of the problem or deficiency, including reference to any supplemental data or observations responsible for determining the problem or deficiency. • Location of the problem or deficiency, including how and when the problem or deficiency was discovered. In addition, an estimate of how long the problem or deficiency has existed should be included as well as an opinion as to the probable cause of the problem or deficiency. • A recommended corrective action for resolving the problem or deficiency should also be included in the report. If the corrective action has already been imple- mented, then the observations and documentation to show that the problem or deficiency has been resolved should be included. If the problem or deficiency has not been resolved by the end of the day upon which it was discovered, then the report will clearly state that it is an unresolved problem or deficiency. A problem/deficiency report will be submitted to the CQAE by the end of the working day during which the problem or deficiency occurred. The CQAE will then inform the Owner/Operator as soon as possible. If the problem or deficiency has not been resolved, then the CQAE and the report preparer will discuss the issue with the Owner/Operator, and the Owner/Operator will take the necessary corrective actions to resolve the problem or deficiency as soon as practical.

Moisture content specifications will be met for all soils; however, moisture content will not be used as the sole criterion for failing a density test. • Any soils which do not classify as CL or CH by the Unified Soil Classification system shall be reported immediately to the CQAE. • A laboratory determination of hydraulic conductivity greater than 1x10-6 cm/sec for liners or final cover barrier layer will be reported immediately to the CQAE. • If a hydraulic conductivity test fails the specification, at least one additional sample will be collected from the general area (within 25 feet) of the failing test. Based on the initial test and the retest results, the CQAE will determine whether additional tests should be conducted and/or repairs to the liner made to correct the deficiency. 3.1.6 Placement Criteria The low hydraulic conductivity soils shall be placed with emphasis on the following: • Segregation and removal of unsuitable material. • Removal of boulders, cobbles, stumps, and roots. • Removal of structurally weak material (i.e., organic debris). Field densities and moisture contents will be measured in areas where low-hydraulic conductivity compacted clay soil has been placed in order to document that the in-place soils are in substantial conformance with the required specifications. Any backfilling and/or placement of low-hydraulic conductivity soils will be accomplished in accordance with the following requirements: • Observed stones greater than four inches in diameter will be removed from this material during soil homogenizing and moisture conditioning. • No frozen soils will be used for backfilling. Any frozen soils in the compaction work area will be removed. • The loose thickness of layers for clay compaction should be eight inches or less. • Clay compaction will be performed on properly homogenized and moisture conditioned soil so as to accomplish continuous and complete layer bonding and continuity of all soil construction joints. • Clay soils will be compacted to achieve a hydraulic conductivity of ≤1x10-6 cm/sec. • Unacceptable density or moisture content will be reported immediately to the Contractor by the Soils Testing Laboratory. The CQAE shall be notified of any unacceptable densities or moisture contents. Corrective action will consist of moisture conditioning of the soil and/or additional compactive effort as necessary. 3.1.7 Excavation Base Requirements Excavations shall be observed by the CQAE prior to liner or clay fill construction. The CQAE will document all excavation conditions including but not limited to relative DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 15 moisture content, material consistency, stability, slope configuration, and that the base area is graded, according to the plans and specifications. Proof-rolling with heavy equipment will be performed to identify any areas of undesirable material or soft foundation soils and will be observed by the CQAE and/or the Soil Testing Laboratory. Where unacceptable excavation base surface conditions exist, the surface will be re- rolled or over-excavated to reduce the impact of such conditions. When over-excavated, the resulting depression will be backfilled with compacted clay soils. Backfilling will be accomplished in accordance with the field and laboratory testing provisions of Sections 3.1.3 and 3.1.4. The completed and/or repaired excavation will be surveyed according to the provisions of Section 2.3 to determine that the excavation base is in accordance with the plans and specifications. 3.1.8 Compacted Clay Floor and Side Slope Liner The final thickness of the compacted clay floor and side slope liner shall be a minimum of one foot when measured normal to the excavation surface. The liner material shall be placed in layers of approximately equal thickness (not to exceed 8 inches loose). Material thicknesses and proper grades shall be verified by surveying as described in Section 2.4. The liner for each successive module or sub-module within the landfill shall be integrally connected to provide a continuous liner across the landfill floor and side slopes. During extended periods when liner construction is not being conducted, this leading edge of the compacted clay liner will be covered with a minimum of two feet of loose soil to prevent liner desiccation. Bonding of subsequent liner sections will be accomplished by removing the temporary soil liner cover from a strip of the leading edge of the previous liner and lightly scarifying the surface of the liner. After the surface has been scarified, it will be observed for signs of desiccation and repaired as necessary. The Contractor will, if necessary, moisture-condition surfaces to receive clay fill either by addition of water and additional scarification where desiccated, or by disking to reduce water content. Prior to placement of the leachate drainage layer, the final surface of the floor and side slope liner shall be smoothed by compaction with a smooth drum roller or other suitable compactor in order to provide a well-draining surface. 3.1.9 Final Cover The final cover will have a minimum thickness of 3.5 feet measured normal to the slope including a 0.5-foot growth layer overlaying a 1.0-foot rooting zone overlying a 1.5-foot low hydraulic conductivity clay layer overlying a 0.5-foot foundation layer. The thickness of each final cover layer shall be verified as specified in Section 2.6. The foundation layer consists of a 0.5-foot thick compacted lift of soil which will provide a structural basis for construction of the low hydraulic conductivity layer. No specific compaction/density specification is set forth; however, the CQAE shall approve the compaction methods and effort applied to this layer. All clay soils used in final cover construction shall meet the required in place compacted hydraulic conductivity specification of ≤ 1x10-6 cm/sec.

The as-built construction of the berms shall be verified by surveying as specified in Section 2.8. Riprap shall be placed in the drop chutes without damaging the underlying geotextile. Where drop chutes are not parallel to the slope, stones shall be placed at the tops of the chutes to prevent flow of surface runoff parallel to the chute along the cover surface. 3.1.10.2 Sediment Pond Embankment The sediment pond embankments will be constructed using non-granular soils placed in loose 8-inch maximum lifts and compacted/moisture specifications outlined in Table 1. Prior to constructing the embankments, the area beneath the embankments shall be scarified and proof-rolled to the satisfaction of the CQAE. Field moisture density tests shall be conducted at a rate no less than one test per compacted soil lift per embankment. The as-built construction of the embankments shall be verified by surveying as specified in Section 2.8. 3.1.10.3 Culvert Backfill Where non-granular soils are used as the backfill for culverts, the fill shall be placed in loose 8-inch maximum lifts and compacted/moisture specifications outlined in Table 1. 3.1.10.4 Road Where non-granular soils are used as structural fill, the soil shall be placed in loose 8- inch maximum lifts and compacted/moisture specifications outlined in Table 1. The as- built construction of the road shall be verified by surveying as specified in Section 2.9. 3.1.10.5 Anchor Trench Backfill Non-granular soils used for backfilling of anchor trenches shall be moisture-conditioned and wheel-rolled or compacted with a hand operated compactor in the anchor trench to meet design requirements and to the satisfaction of the CQAE. Care shall be taken to not damage the liner during compaction of the soils. The CQAE shall observe all compaction operations in the anchor trench. There are no prescribed quantitative tests for this material; however, at the discretion of the CQAE, laboratory and field testing may be requested to assess moisture, density, and grain size distribution. 3.1.11 Deficiencies and Resolution If a deficiency is discovered in the construction work, the CQAE along with the Soils Testing Laboratory will determine the extent and nature of the defect by additional testing, observation, review of data, or other appropriate means and will then inform the Owner/Operator. The Owner/Operator and the CQAE will direct the Contractor to perform the necessary corrective tasks. The Soils Testing Laboratory will retest the previously defective area, as appropriate, to document the success of corrective action.

In addition, the granular soils must consist of inert and stable materials. The CQAE will observe the spreading and grading of the granular material in the leachate sump, LHP sump, and the leachate drainage layer and document that it meets the project specifications. This observation will also be conducted to quickly detect potential and/or actual damage to the underlying geosynthetics upon which the material is being placed. Where damage is suspected, the underlying component surface will be exposed and observed to determine its condition. Actual damage will be fully documented as well as corrective action taken. 3.2.5 Placement Criteria The following placement criteria will be used by the Contractor while installing the drainage layer or the sump gravel. • During placement of the leachate drainage layer over the clay liner, at least 1.5 feet of granular soils shall be maintained between the earth-moving equipment and underlying liner except for during final spreading when a minimum of 0.5 feet separation shall be maintained. Final spreading of the leachate drainage layer shall be conducted using a low ground pressure bulldozer approved by the CQAE. • A minimum final thickness of 0.5 feet of drainage material will be placed over the floor liner. • During placement of gravel in the leachate sump, a minimum of 1.5 feet of granular material shall be maintained between the earth moving equipment and the underlying liner components. • The CQAE will observe the spreading and grading of the granular material in the leachate sump and document that it meets the project specifications. This observation will also be conducted to quickly detect potential and/or actual damage to the underlying geosynthetics upon which the material is being placed. Where damage is suspected, the underlying component surface will be exposed and observed to determine its condition.

All on site handling is the responsibility of the Installer. The geomembrane will be protected during shipment from excessive heat or cold, puncture, cutting, or other damaging or deleterious conditions. Upon arrival, the Installer shall inspect all materials for defects in the manufacturing process and for damage during transportation. Materials judged by the CQAE to be severely damaged shall be rejected and removed from the site. Minor damage and defects shall be repaired by the Installer. Geomembrane rolls will be stored on site in a manner, which prevents excessive ultraviolet exposure prior to installation. The CQAE will be responsible throughout the pre-construction, construction, and post construction periods for observing and documenting that the Installer provides adequate handling equipment for use in moving geomembrane rolls and that the equipment for the moving of the geomembrane rolls preserves the integrity of the geomembrane. The Installer will be responsible for making certain that the manufacturer, type, and thickness of each roll in a shipment are correct. The CQAE will also maintain a log of DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 25 geomembrane roll deliveries throughout the construction process. This log shall include, at a minimum, the following: • Manufacture date. • Date of receipt at the site. • Roll and lot batch numbers. 4.1.3 Foundation The Earthwork Contractor will be responsible for preparing the subgrade according to the Design Plans and Drawings and this CQAQCP. After the underlying surface has been accepted by the CQAE, it will be the Installer's responsibility to report to the CQAE any change in that surface that may require repair work. The supporting surface will be examined by the Installer and the CQAE to evaluate the surface conditions immediately prior to placement of the HDPE geomembrane. The CQAE and Geosynthetic Installer shall document in the daily report that the foundation layer surface condition is compatible with the geosynthetics to be installed. All observations by the CQAE and Geosynthetics Installer shall be documented in writing. 4.1.4 Placement Criteria A panel layout drawing will be prepared by the Installer and provided to the CQAE at least three days prior to installation of the geomembrane. Geomembrane placement will not be conducted at ambient temperatures below 40ºF (unless approved by the manufacturer and the CQAE), during precipitation or fog, in ponded water, or during excessive winds. Where adjacent or transverse panels are seamed, temperature effects on these panels should be taken into account to reduce the problem of "fish mouths" which may be encountered in the seaming process. The CQAE will document the following: • The prepared soil surface for the geomembrane has not deteriorated since previous acceptance. • The equipment used does not damage the geomembrane by handling, heat, leakage of hydrocarbons, or by any other means. • Personnel working on geomembranes do not smoke, wear damaging clothing, or engage in activities that would damage the geomembrane. • The method of unrolling the geomembrane does not cause scratches or crimps in the geomembrane. • The method and sequencing used to place the rolls minimizes wrinkles and seaming problems. • Adequate means are used to prevent uplift by wind while preventing damage to the geomembrane or supporting earthen foundation. • Direct contact with the geomembrane will be minimized. The geomembrane will be protected by geotextiles or extra geomembrane materials in areas where excessive traffic is anticipated. • Heavy construction equipment shall not be allowed to move directly on any deployed geomembrane. This includes rubber-tired vehicles such as automobiles and pickup trucks but does not include light weight equipment like all-terrain vehicles.

Ground contact pressure equipment of less than 5.0 psi is required. • For lift heights of greater than 12.0 inches, proportionately heavier placement equipment may be used. • Construction machinery must not perform sudden starts, stops or sharp turns over the geomembrane. • Cover material must be placed from the bottom of slopes to the top. • Cover material must be placed in such a manner as not to induce wrinkles in the underlying geomembrane. • All equipment that the contractor proposes to use within the geomembrane footprint must be approved by the CQAE. 4.1.5 Construction Field Seams This section covers quality assurance/quality control procedures for seaming rolls of geomembrane into a continuous liner. This plan requires 100 percent non-destructive testing of all field seams. All seams must be logged by the CQAE or the Installer. The Installer will provide the CQAE with seam layout drawings for each panel showing each expected seam. The CQAE will review the seam layout drawing and document that it is consistent with accepted practice and the Design Plans and Drawings. No seaming will be performed without the CQAE's approval. In general, seams should be oriented parallel to the line of maximum slope, so they are oriented along, not across, the slope. In corners and at other odd geometric intersections, the number of seams should be minimized. All horizontal seams across the slope must be approved by the CQAE. Only end-of-panel seams may be approved. A seam numbering system, that is compatible with the geomembrane roll numbering system, will be agreed upon by the Installer and the CQAE. Prior to seaming, the seam area shall be clean, free of moisture, dust, dirt, debris of any kind, and foreign material. If seam overlap grinding is required, it shall be performed ac- cording to the Manufacturer's instruction within one hour of the seaming operation and in a way that does not damage the geomembrane. Seams shall be aligned with the fewest possible wrinkles. 4.1.6 Seaming Equipment Approved processes for field seaming are double-fusion welding and extrusion welding. Double-fusion welding shall be used for all seams except where space and access constraints prohibit its use. Fusion welding application may be impractical where space is limited in some parts of the site. Only apparatus, which have been specifically approved by the CQAE, shall be used. Proposed alternate processes shall be documented and submitted for approval to the CQAE. Double-fusion welding using a hot wedge seaming device is the preferred method of seaming HDPE geomembrane. The fusion welding apparatus shall be equipped with gauges giving the applicable temperatures and pressures. Prior to installation of any geomembrane material, the Installer shall submit seaming quality control records, including ambient temperatures and applicable apparatus temperatures and pressures DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 27 and trial seam results to the CQAE. Trial seam results shall be logged by the Installer or the CQAE. The Installer shall meet the following requirements regarding use, availability, and cleaning of extrusion welding equipment to be used at the site: • At least one spare operable double-fusion and extrusion seaming device will be maintained on site at all times. • The welding apparatus will be equipped with a continuous temperature monitor in the barrel and at the nozzle. • Equipment used for seaming shall not damage the geomembrane. • The extruder will be cleaned and purged prior to beginning seaming, and at any time that seaming operations are stopped, until all heat-degraded extrudate has been removed from the barrel. • The electric generator for the equipment will be placed on a smooth base in such a way that no damage occurs to the geomembrane. • A smooth insulating plate or fabric will be placed beneath hot equipment to protect the geomembrane. The Installer, and if applicable the Manufacturer, will provide documentation to the CQAE regarding the quality of extrudate used in the welding apparatus. At a minimum, the extrudate should be compatible with the base liner material and contain the same grade and quality of PE resin as used in the base material. 4.1.7 Seamer Qualifications All personnel performing seaming operations will be qualified by experience and by successfully passing seaming tests for the type of seaming equipment to be used. All seamers must have seaming experience of a minimum of 500,000 ft2 of polyethylene geomembrane using the same type of equipment to be used on this project. The most experienced on site seamer, the "master seamer" (a seamer that has successfully seamed a minimum of 2,000,000 ft2 of polyethylene geomembrane using the same type of equipment to be used on this project) will have direct supervisory responsibility at the site over less experienced seamers. The Installer shall provide documentation of the qualifications of the seaming crew to the CQAE. 4.1.8 Weather Conditions During Seaming The range of weather conditions under which geomembrane seaming can be performed are as follows: • Between ambient temperatures of 40oF and 50oF, as measured 6-inches above the sheet, seaming will be performed only if the geomembrane is preheated by either the sun or hot air device, provided there is no excessive ambient cooling resulting from wind conditions. • Unless otherwise authorized in writing by the CQAE, no seaming will be attempted at an air temperature colder than 40ºF or warmer than 104ºF as measured 6-inches above the sheet. • The geomembrane will be dry and protected from the wind. • Seaming will not be performed during any precipitation event. • Seaming will not be performed in areas where ponded water has collected be- neath the surface of the geomembrane. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 28 The CQAE will document that these requirements are met by the Installer and will document the actual weather conditions during the installation. 4.1.9 Overlapping and Temporary Bond The CQAE or installer will document the following: • The length of the geomembrane overlap. • The geomembrane overlap is adequate for the seaming process that is used. • Procedures used to temporarily bond adjacent geomembrane rolls shall not damage the geomembrane. 4.1.10 Trial Seams Trial seams will be made on fragment pieces of membrane to document that the seaming conditions are adequate. Such trial seams will be made at the beginning of each seaming period, and at least once every four hours thereafter, for each seaming apparatus used that day. Each seamer will make at least one trial seam each day. All trial seams will be made under the same conditions as actual seaming work. Trial seams will be logged and documented in the Certification Report. The trial seams will first be examined for squeeze out, foot print, pressure, and general appearance by the Installer. If a seam fails any of these examinations, a new trial seam will be performed until satisfactory seams are obtained. The trial seam samples will be a minimum of 3-feet long by 1-foot wide after seaming, with the seam oriented lengthwise and with the overlap described previously. A minimum of four, 1-inch wide specimens will be cut from each end of each trial seam sample by the Installer. The specimens or "coupons" will be tested for "peel" and “shear” in the field using a calibrated tensiometer. A passing test is when the break is ductile and occurs at the edge or outside the seam but not in the seam. A failure is defined as the seam or weld peeling. Strength values used in the trial seams shall be the same as those used for destructive seams (refer to Table 10 in Section 4.1.13.3). If a specimen fails, the entire trial seam shall be repeated. If the additional specimen fails, the seaming apparatus or seamer shall not be accepted until corrective measures are performed and two successive trail seams are successfully completed. After completion of these tests, the remaining portion of the passing trial seam will be logged and retained for reference if any further information might be required. The results of all test seams shall be forwarded to the CQAE. 4.1.11 General Seaming Procedures The general seaming procedures are as follows: • Large "fish mouths" (Large fish mouths are of a size that will prevent airtight bonding between geomembrane panels.) or wrinkles at the seam overlaps will be cut along the ridge of the wrinkle in order to achieve a flat overlap. The cut “fish mouths” or wrinkles shall be seamed, and any portion where the overlap is inadequate will then be patched with an oval patch of the same membrane, extending a minimum of six inches beyond the cut in all directions. • For double fusion welding, each overlap and the sheet below the overlap shall be hand-wiped clean immediately prior to welding. • On the side slopes seaming will extend into the anchor trenches. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 29 • At locations where the initial seam cannot be nondestructively tested, the seam will be cap stripped with the same geomembrane material. The CQAE will ob- serve the cap stripping to document the uniformity and completeness of the work. 4.1.12 Nondestructive Testing Each field seam will be nondestructively tested over the full length of the seam to the extent practical. Any seams, which cannot be effectively tested, will be reported to the CQAE. The purpose of the nondestructive testing is to determine the continuity of the seams. The method for conducting nondestructive seam testing is pressure testing the open channel between the double fusion welds. GRI method GM6 shall be used to test double fusion welded seams. This method requires the pressurization of the open channel at 27 to 30 psi with a maximum pressure drop of 3 psi over five minutes for 60-mil HDPE. The vacuum box or the ultrasonic shadow method may be used on extrusion welds in accordance with GRI specifications. Other test methods may be used only upon approval by the CQAE. The CQAE will perform the following tasks related to seam testing: • Observe nondestructive seam testing and examine all seams for squeeze-out, footprint, pressure, and general appearance. Failure of these criteria will be considered as failure of the seam, and repair or reconstruction will be required. • Document the location, date, test unit number, name of tester, and outcome of all testing. • Inform the Installer of any required repairs. 4.1.13 Destructive Testing Destructive seam tests shall be conducted throughout the seaming project at locations selected by the CQAE. The tests shall be conducted so that results are obtained prior to covering the geomembrane with another material. The purpose of the tests is to ensure that welds are fully integrated and to evaluate seam strength. At a minimum, the CQAE or Installer shall document, in the daily report, the following information related to all destructive seam samples: • The location by seam and sample number of the samples. • The results of all field testing of destructive samples • Actions taken as a result of testing. • Repairs of the sampled seams. 4.1.13.1 Test Location and Frequency Destructive samples shall be collected at locations specified by the CQAE at a minimum rate of one sample for every 750 feet of seam. The seaming technician shall not be informed in advance of the time when, or locations where, seam samples will be taken. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 30 4.1.13.2 Sampling Procedure Samples shall be cut by Installer at locations specified by the CQAE. A number shall be assigned to each sample based on the seam number and sample sequence. The sample location and identifier shall be recorded in the daily report. At each sampling location, two types of samples will be collected. Two sample coupons will be collected for field testing. Each of these coupons shall be 1 inch wide by 12 inches long with the seam centered parallel to the length. The minimum distance between these two coupons shall be 42 inches. If both sample coupons pass the field test described in Section 4.1.13.3, a sample shall be cut from the seam between the locations of the two coupons. This sample shall be cut into three parts and distributed as follows: • One portion to the Geosynthetic Quality Assurance Laboratory for testing (12 inches wide by 12 inches long) • One portion to the Installer for testing (12 inches wide by 18 inches long) • One portion to the CQAE for archive storage (12 inches wide by 12 inches long). Sample size may vary slightly depending on the needs of each party in the distribution list. Final sizes shall be determined at a Pre-construction meeting. 4.1.13.3 Testing Procedure Testing shall be conducted for shear and peel. Shear testing applies a tensile stress from the top sheet through the weld and into the bottom sheet. Peel testing peels the top sheet back against the overlapped edge of the bottom sheet in order to observe how separation occurs. The peel test indicates whether or not the sheets are continuously and homogeneously connected through the seam. The specifications for seam strength are presented in Table 10. Table 10 Seam Strength (ppi) for 60-mil HDPE Test Number of Coupons Method* Fusion Weld Strength Extrusion Weld Strength Peel 2 ASTM D6392 90 78 Shear 1 ASTM D6392 126 126 * As modified by NSF 54 4.1.13.4 Procedures Following Destructive Test Failure All acceptable seams must be bounded by two locations from which samples passing destructive tests have been taken. There are two options for mitigation of a failed destructive test: • Reconstruct the seam between any two passed test locations; or • Trace the welding path to an intermediate location (10 feet maximum from the point of the failed test in each direction) and take a small sample coupon for an additional field test at each location. If these additional samples pass the tests, then full samples (as described in Section 4.1.13.2) are taken. If these samples pass the tests, then the seam is reconstructed between these locations. If either sample fails, the process is repeated to establish a zone in which the field seam will be reconstructed.

The CQAE will examine each roll for damage after placement but prior to seaming and will determine which rolls or portions of rolls should be rejected, repaired or accepted. Damaged rolls or portions of rolls, which have been rejected, will be marked, and their removal from the site will be recorded by the CQAE. All seam and non-seam areas of the geomembrane will be examined and documented by the CQAE for identification of defects, holes, blisters, undispersed raw materials, large wrinkles, and any signs of contamination by foreign matter. The surface of the geomembrane will be clean at the time of examination. Each location, which fails examination, will be marked by the CQAE and repaired by the Installer. Work will not proceed in any area where defects are identified until suitable repairs are made. Several procedures exist for the repair of flawed areas. The final decision as to the appropriate repair procedure will be agreed upon between the Installer and the CQAE prior to commencement of the repair. The following procedures are available: • Spot Seaming - used to repair small tears, pinholes, or other minor localized flaws. • Patching - used to repair large holes, tears, undispersed raw materials, and con- tamination by foreign matter. • Capping - used to repair large lengths of failed seams. • Removing the Bad Seam and Replacing with a Strip of New Material Seamed in Place - used for repairing large lengths of fusion seams. • Other - as agreed upon by the Installer and the CQAE. At a minimum, the following provisions will be provided for repairs: • The geomembrane below large caps shall be appropriately cut to avoid water or gas collection between the two sheets. • Patches or caps will extend at least six inches beyond the edge of the defect, and all corners of patches will be rounded with a radius of three inches minimum. Each repair will be examined, numbered, and logged by the CQAE. 4.1.15 Placement of Leachate Collection and Drainage Materials Placement of 16 oz. nonwoven geotextile and granular soils on top of the HDPE geomembranes will be conducted by the Contractor in such a manner as to confirm the following: • Slippage of the geosynthetics on the underlying clay liner is minimal. • No damage of the geomembrane or underlying clay liner occurs. • No excess tensile stresses are imposed on the geosynthetics. • Heavy construction equipment shall not be allowed to move directly on any deployed geomembrane. This includes rubber-tired vehicles such as automobiles and pickup trucks but does not include light weight equipment like all-terrain vehicles. • The minimum initial lift height of soil placed over geosynthetics shall be no less than 6 inches. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 32 • Between this value and 12 inches, low ground pressure placement equipment shall be used. Ground contact pressure equipment of less than 5.0 psi is required. • For lift heights of greater than 12 inches, proportionately heavier placement equipment may be used. • Construction machinery must not perform sudden starts, stops or sharp turns over the geomembrane. • Cover material must be placed from the bottom of slopes to the top. • Cover material must be placed in such a manner as not to induce wrinkles in the underlying geomembrane. • All equipment that the contractor proposes to use within the geomembrane footprint must be approved by the CQAE. 4.1.16 Anchor Trench System Construction and Backfilling A trench will be used for anchoring the geosynthetics as indicated on the design plans and drawings. The anchor trench will be excavated to the specifications shown on the Design Plans and Drawings unless otherwise specified by the CQAE. Note that the anchor trench is used for the convenience of construction and securing the liner during construction. The anchor trench is not a required element of the post-construction liner stability. The anchor trench shall be backfilled with non-granular soil (SC or CL) as approved by the CQAE. The soil shall be placed in maximum 8-inch lifts, moisture conditioned and wheel-rolled with a rubber tire machine or other method approved by the CQAE. 4.2 GEOSYNTHETIC CLAY LINER (GCL) The GCL shall be Bentomat ® ST or equivalent. The GCL shall consist of a layer of natural sodium bentonite clay encapsulated between two geotextiles and shall comply with all of the criteria listed in this section. Only reinforced GCL shall be used. Prior to using an alternate GCL, the Installer must furnish independent test results demonstrating that the proposed alternate material meets all requirements of this specification. The Installer also must obtain prior approval of the alternative GCL by the CQAE. 4.2.1 GCL Properties The GCL shall substantially comply with the properties shown in Table 11. The minimum acceptable dimensions of full-size GCL panels shall be 150 feet long by 15 feet wide. Short rolls (less than 150 feet but greater than 70 feet) may be supplied at a rate no greater than three rolls per truckload or three rolls per 36,000 ft2 of GCL, whichever is less. The length of all short rolls shall be clearly marked on the outer packaging. A 6-inch overlap guideline shall be imprinted on both edges of the upper geotextile component of the GCL as a means of facilitating quality assurance during seaming. Lines shall be printed in easily visible, non-toxic ink that does not negatively impact the performance of the GCL. Conformance sampling and testing of the proposed GCL will be performed as presented below. If possible, the conformance sampling shall be performed by the Manufacturer at the plant prior to shipping to the site. Samples may also be selected from GCL rolls delivered to the site for offsite conformance testing by a geosynthetics testing laboratory other than the Manufacturer. Conformance testing will be performed using the test DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 33 methods in Table 11, at the frequency of one sample per 100,000 square feet (sf) with a minimum of one test per lot. Conformance testing will meet the specifications listed in Table 11 and will include the following: • Index Flux • Mass per Unit Area • Moisture Content of Bentonite Table 11 GCL Properties Material Property Test Method Test Frequency Required Values Bentonite Moisture Content ASTM D2216 1 per 50 tons 12 percent max Bentonite Swell Index ASTM D5890 1 per 50 tons 24 mL/2g min.

The GCL Manufacturer shall provide the Contractor or other designated party with manufacturing QAQC certifications for each shipment of GCL. The certifications shall be signed by a responsible party employed by the GCL Manufacturer and shall include: • Certificates of analysis for the bentonite clay used in GCL production demonstrating compliance with the swell index and fluid loss specifications in Table 11. • Manufacturer’s test data for the finished GCL product of bentonite mass/area, GCL tensile and peel strength demonstrating compliance with the specifications in Table 11. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 34 • GCL lot and roll numbers supplied for the project and corresponding shipping information. • Manufacturer’s test data for finished GCL product for index flux, permeability, and hydrated internal shear strength showing compliance with the specifications in Table 11. 4.2.3 GCL Product Labeling Prior to shipment, the GCL Manufacturer shall label each roll in a manner that clearly identifies the following information: • Product identification including Manufacturer’s name, address, brand name, and product code. • Lot number and roll number. • Roll length, width, and height. 4.2.4 GCL Product Packaging The GCL shall be wound around a rigid core whose diameter is sufficient to facilitate handling with mechanized equipment. The core is not necessarily intended to support the roll for lifting but shall be sufficiently strong to prevent collapse during transit. All rolls shall be labeled and packaged in materials that are resistant to photo degradation by ultraviolet light. 4.2.5 Accessory Bentonite The granular bentonite used for seaming and penetration sealing shall be made from the same natural sodium bentonite material as used in the manufacture of the GCL. 4.2.6 GCL Shipping and Handling The Manufacturer assumes responsibility for initial loading of the GCL. Shipping will be the responsibility of the party arranging for the freight transportation. Unloading, on site handling, and storage of the GCL are the responsibility of the Installer or the Installer’s designated representative. A visual inspection of each roll shall be made during unloading to identify if any packaging has been damaged. Rolls with damaged packaging shall be marked and set aside for further inspection. The packaging shall be repaired as necessary to protect the GCL from damage during storage and handling. The party responsible for unloading the GCL shall contact the Manufacturer prior to shipment to ascertain the appropriateness of proposed unloading methods and equipment. 4.2.7 GCL Storage Storage of the GCL rolls shall be the responsibility of the Installer. A level, dry, well- drained, and dedicated storage area shall be selected at the job site outside of high traffic areas. Rolls shall be stored in a manner that prevents sliding or rolling from the stacks. Stacks shall be no higher than four rolls. All stored GCL and accessory bentonite shall be covered with plastic sheeting or tarpaulins until their installation. The integrity and legality of the roll labels shall be preserved during storage. DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 35 4.2.8 GCL Installation GCL rolls shall be delivered to the working area of the site in their original packaging. Immediately prior to deployment, the packaging shall be carefully removed without damaging the GCL. The non-woven side of the GCL shall be placed up. Equipment that could potentially damage the GCL or subgrade shall not be allowed to travel directly on it. Care shall be taken to minimize dragging GCL across the subgrade. At the direction of the CQAE, a temporary geosynthetic slip sheet shall be used when necessary to reduce friction during GCL placement. The GCL shall be placed so that longitudinal panel seams are parallel to the direction of the slope. Seams shall be located at least three feet from the toe and crest of slopes steeper than 5:1. All GCL panels shall lie flat on the underlying surface with no wrinkles or folds. Only as much GCL shall be deployed as can be covered with geomembrane at the end of the working day unless otherwise approved by the CQAE. If premature hydration of the GCL occurs, (i.e., prior to covering the GCL), the CQAE shall determine whether or not the GCL shall be replaced. The GCL Installer must have installed at least 500,000 ft2 of GCL or must provide the CQAE with satisfactory evidence that the GCL will be installed in a competent and professional manner. 4.2.9 GCL Seaming The GCL seams are constructed by overlapping their adjacent edges. Care should be taken to ensure that the overlap zone is not contaminated with loose soil or other debris. The minimum dimension of the longitudinal panel overlap shall be six inches for the finished (i.e. bentonite enhanced) seam. The minimum overlap at the end of roll seams shall be 24 inches. The panel seams shall be shingled in the direction of the grade. Granular bentonite shall be used to enhance the seams. The underlying edge of the overlap panel shall be exposed, and a continuous fillet of granular sodium bentonite shall be applied along a zone defined by the edge of the underlying panel and the 6-inch line. The bentonite shall be applied by the Installer at a minimum rate of 0.25 pound per linear foot of seam. In the leachate sump areas where two thicknesses of GCL are placed, the seams of the top layer shall be offset from underlying layer seams by at least 24 inches. The contractor shall use a smooth HDPE slip sheet as necessary to facilitate positioning the top GCL layer over the underlying layer. The GCL shall be cut with a sharp utility knife. Cuts shall be smooth and clean. 4.2.10 GCL Damage Repair If a GCL panel is torn, punctured, perforated, etc. during installation, it shall be replaced or repaired per the direction of the CQAE. Patches shall be sized so that a minimum 12- inch overlap is achieved around the damaged area. Prior to placement of the patch, dry bentonite shall be placed around the damaged area. If there is no potential for dislodging the patch during covering operations, the patch shall be secured to the damaged area using appropriate adhesive per CQAE approval.

A photo log will be created containing photos of all phases of the GCL installation. 4.3 REINFORCED POLYETHYLENE GEOMEMBRANE The reinforced polyethylene geomembrane (RPE) used on this project shall be 45-mil or equal. 4.3.1 RPE Manufacturing • Prior to delivery of any RPE geomembrane panels to the site, the Manufacturer will provide the CQAE with the following information: The resin supplier, supplier location, and brand name • Any test results conducted by the geomembrane and/or resin manufacturer to document the quality of the resin used in the membrane fabrication • The QC plan that the geomembrane manufacturer will be using for the geomembrane being supplied. Every panel of RPE geomembrane delivered to the site must be manufactured and inspected by the Manufacturer according to the following requirements: • The materials used for the geomembrane must consist of first-quality 100% virgin products designed and manufactured specifically for the purpose of this work, which must have been satisfactorily demonstrated to be suitable and durable for such purposes. • The geomembrane must be free from holes, pin holes, bubbles, blisters, excessive gels, undispersed resins, and/or carbon black, or contamination by foreign matter. • The geomembrane must be composed of a heavy encapsulated 1300 denier polyester bi-directional reinforcement. • All factory seams must have a minimum seam width of 1.5 inch scrim to scrim. The RPE Geomembrane Manufacturer will perform the tests listed in Table 12 at the frequency of one test per every 100,000 feet of material and will report the results to the CQAE. The RPE Geomembrane Manufacturer will provide certification based on tests performed by the Manufacturer’s laboratory, or other outside laboratory contracted by the Manufacturer, that the membrane supplied under this plan will substantially comply with specifications listed in Table 12. Conformance sampling and testing of the proposed RPE will be performed as presented below. If possible, the conformance sampling shall be performed by the Geomembrane Manufacturer at the plant prior to shipping to the site. Samples may also be selected from geomembrane rolls/panels delivered to the site for offsite conformance testing by a geosynthetics testing laboratory other than the Geomembrane Manufacturer. Conformance testing will be performed at the frequency of one sample per 100,000 square feet (sf) and minimum 1 test per lot and will include: • Sheet Thickness • Sheet Density DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 37 Conformance samples shall be tested in accordance with Table 12 methods and shall meet properties listed in Table 12. 4.3.2 Delivery, Handling, and Storage of RPE Geomembrane Rolls • Transportation of the RPE geomembrane panels to the job site is the responsibility of the Geomembrane Manufacturer. All on site handling is the responsibility of the Installer. The geomembrane will be protected during shipment from excessive heat or cold, puncture, cutting, or other damaging or deleterious conditions. Upon arrival, the Installer shall inspect all materials for defects in the manufacturing process and for damage during transportation. Materials judged by the CQAE to be severely damaged shall be rejected and removed from the site. Minor damage and defects shall be repaired by the Installer. • The Installer will be responsible for making certain that the Manufacturer, geomembrane type, and thickness of each panel in a shipment are correct. The CQAE will also maintain a log of geomembrane panel deliveries throughout the construction process. This log shall include, at a minimum, the following: • Manufacture date • Date of receipt at the site • Panel and lot batch numbers. • The CQAE will be responsible throughout the pre-construction, construction, and post construction periods for observing and documenting the handling and storage of the RPE geomembrane to ensure that the integrity of the material is preserved. The CQAE will ensure the following: • Fabricated panels (accordion-folded in one direction, rolled in the other direction) will be unloaded from trucks in such a way that no damage occurs to the geomembrane. • Fabricated panels accordion folded in both directions will not be used. • Fabricated panels on pallets will be moved by forklifts. • Folds of fabricated panels shall be examined for damage, particularly at kinks in the folds. • All material will be stored on smooth clean dry level surfaces such that it will not be damaged, become dirty, or get wet internally. • Depending on the timeline of the project, material shall be stored in a safe central location then staged at appropriate intermediate locations for deployment. • Fabricated panels will ultimately be placed in the correct location and in the correct orientation for deployment as shown on the protective packaging or in contained deployment instructions. 4.3.3 Foundation The Earthwork Contractor will be responsible for preparing the subgrade according to the Design Plans and Drawings and this CQAQCP. After the underlying surface has been accepted by the CQAE, it will be the Installer's responsibility to report to the CQAE any change in that surface that may require repair work. The supporting surface will be examined by the Installer and the CQAE to evaluate the surface conditions immediately prior to placement of the RPE geomembrane. The CQAE and Installer shall document in the daily report that the subgrade surface condition is compatible with the geosynthetics to be installed. All DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D Eagle Landfill CQAQCP December 5, 1995 Revised May 10, 1996 Revised January 2020 Revised September 2021 Page 38 observations by the CQAE and Geomembrane Installer shall be documented. It is the Earthwork Contractor’s responsibility to maintain the subgrade surface in a condition acceptable to the CQAE and Geomembrane Installer for geomembrane installation. The RPE geomembrane must not be susceptible to differential settlement and there shall be no standing water on the subgrade when the liner is placed. 4.3.4 Placement Criteria A panel layout and deployment instructions will be prepared by the Installer and provided to the CQAE at least ten calendar days prior to installation of the RPE geomembrane. Panels shall by unrolled and unfolded as indicated in the instructions. Unfolding shall be done with a person every 15 to 30 feet, depending on the size/weight of the panel. RPE geomembrane placement must not be conducted during strong or gusty winds or during precipitation events and lightning storms. The CQAE will perform/document the following: • Evaluate and document weather conditions for geomembrane placement and inform MCSWM and the Installer when weather conditions do not meet specifications, so a determination of installation can be made. • Monitor and document geomembrane placement as well as conditions of panels as placed: • Noting panel defects, tears, or other deformities • Measuring in-place panel dimensions • Recording panel numbers. • Document that the equipment used does not damage the geomembrane by handling, heat, leakage of hydrocarbons, or by any other means. • Document that the prepared soil surface for the geomembrane has not deteriorated since previous acceptance. • Document that personnel working on geomembranes do not smoke, wear damaging clothing, or engage in activities that would damage the geomembrane. • Document that adequate means are used to prevent uplift by wind while preventing damage to the geomembrane or supporting earthen foundation. • Document that the direct contact with the geomembrane will be minimized. The geomembrane will be protected by geotextiles or extra geomembrane materials in areas where excessive traffic is anticipated. • Document that the heavy construction equipment shall not be allowed to move directly on any deployed geomembrane. This includes rubber tired vehicles such as automobiles and pickup trucks but does not include lightweight equipment like all-terrain vehicles. • Document that the construction machinery must not perform sudden starts, stops, or sharp turns over the geomembrane. • Document that the cover material, if applicable, must be placed from the bottom of slopes to the top. • Document that the cover material must be placed in such a manner as not to induce wrinkles in the underlying geomembrane. • Document all equipment that the contractor proposes to use within the geomembrane footprint is approved by the CQAE.

Welding should be done as uniformly and consistently as possible. The objective is to melt the two surfaces and to allow them to cool and solidify as one integral body. When the weld is sectioned there should not be a well-defined interface, nor should there be any particulates or voids along the weld line. There should be no crimps due to overheating. The adjacent geomembrane should not be overheated and oxidized such that it becomes brittle. The cross sections of welds shall be examined for symmetry, lack of crimping (overheating), and the presence of voids and foreign particulates. If voids and particulates are present, the weld will be rejected. The Geosynthetic Manufacturer is responsible to complete their own fabrication seam QA/QC during manufacturing. The contractor shall submit the Geosynthetic Manufacturer’s QA/QC procedures to the CQAE. The contractor must submit the Geosynthetic Manufacturers QA/QC seam test results, certifications, and test reports for all welds completed by the Geosynthetic Manufacturers to the CQAE. If field seaming is necessary, all personnel performing seaming operations must be qualified by experience and by successfully passing seaming tests for the type of seaming equipment to be used. All seamers must have seaming experience of a minimum of 500,000 ft2 of RPE geomembrane using the same type of equipment to be used on this project. The most experience on-site seamer, the “master seamer” (a seamer who has successfully seamed a minimum of 2,000,000 ft2 of RPE geomembrane using the same type of equipment to be used on this project) will have direct supervisory responsibility at the site over less experienced seamers. The Installer shall provide documentation of the qualifications of the seaming crew to the CQAE. 4.3.6 Defects and Repairs This section applies to all defects including damage during placement and repairs from examinations, tests, or visual observations performed on the RPE geomembrane material and on field seams. All areas of the RPE geomembrane will be visually observed and documented by the CQAE for identification of defects, holes, blisters, undispersed raw materials, large wrinkles, and any signs of contamination by foreign matter. The surface of the geomembrane will be clean at the time of visual observation. Each location that fails visual observation will be marked by the CQAE and repaired by the Installer. Work will not proceed in any area where defects are identified until suitable repairs are made. Several procedures exist for the repair of flawed areas. The final decision as to the appropriate repair procedure will be agreed upon between the Installer and the CQAE prior to commencement of the repair. The following procedures are available: • All non-penetrating linear flaws less than 0.125 inches wide may be repaired with no more than one extrusion bead of the same base polymer as the geomembrane. • Penetrating holes less than 0.125 inches in diameter that do not expose scrim yarns may also be repaired with no more than one bead application.

The patch shall extend at least three inches from the edge of the nearest damage if the damaged area is less than one inch in diameter. When damage exceeds one inch in diameter, the patch shall extend at least six inches from the nearest damage. Under no circumstances will parallel and overlapping beads be used to fill in a flawed area or a gap. All patch extrusion welds shall be vacuum box tested and hot air patches can be either air lanced or vacuum tested and the results recorded. Each repair will be examined, numbered, and logged by the CQAE following these procedures: • Performing systematic visual observation of the entire surface of the RPE geomembrane to locate and document defects and indicate for each defect the type of repair that is required • Monitoring and recording the repair of defects and the non-destructive testing of all repairs • Recording the location and the nature of all defect repairs. 4.3.7 RPE Geomembrane Electronic Leak Location Survey An electronic leak location survey of the geomembrane may be performed at the option of the Owner and CQAE. QA associated with an electronic leak location survey would include the following: • Determination of the suitability of site conditions for the survey • Performance of the survey in accordance with ASTM D 7007 (water and soil- covered liners) to identify potential leak locations of the installed geomembrane • Potential leak locations would be marked with flags, paint, or other means to clearly locate the areas. Location coordinates would be recorded • Observation and documentation of repairs in accordance with project specifications, as applicable • Following repairs to initially identified perforations, the area at and generally around the repair will be re-surveyed to determine repair success. This process will be repeated until all identified perforations have been repaired and successfully re-tested. 4.3.8 Field Reporting and Documentation Documenting and reporting methods will be implemented to allow the systematic recording of results of on-site monitoring and testing. Reporting forms will be used for panel placement. Unique identifying numbers will be assigned to each panel and used to reference panel location. An Installer’s certificate of subgrade acceptance will be obtained prior to panel placement. Panel location diagrams will be kept showing locations of all panels. These diagrams will be updated on a daily basis.

WOLCOTT, CO 81655 ⦁Q: Can the start date be moved up if weather allows? A: Yes, the start date can be moved up if weather conditions allow. ⦁Q: Where will all the shale be dumped at , is there more than one location to dump at? A: There are multiple stockpile locations located around the landfill facility. The main stockpile location will be on the north side of the landfill property next to the Construction and Demolition Diversion site. ⦁Q: What if the shale cannot be ripped with a dozer will there be an item for blasting ,or will we deal with that later? A: This will be addressed at that time if the shale cannot be handled with a dozer. Anything smaller than a D8 size dozer will more than likely be ineffective in ripping the shale. ⦁Q: Will the contractor need to reshape all of the existing slopes around the hole? A: Areas that are disturbed, outside of Mod 9A should be graded similar to what was in place prior to the Mod 9A construction. ⦁Q: How will you handle the bottom of the excavation with the shale ,it will not be level. Will we need to add soil or extra clay material as a leveling course ? A: The compacted clay liner needs to be at least 12 inches thick at all locations and the final clay liner surface needs to meet the design contours. Use the clay to “fill in” the low areas. Use the shale to grade the subgrade assuming the shale breaks into smaller sized pieces. ⦁Q: Can you verify that the county will control the leachate if it begins leaking into 1 DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D the work site? A: Eagle County Landfill staff will assist in leachate control, if necessary. ⦁Q: If groundwater is encountered, will a dewatering permit need to be provided by the contractor? A: We do not believe that we will encounter any significant groundwater. If by chance groundwater is encountered and needs to be pumped out, the contractor can pump the groundwater into the sedimentation pond at the south end of the landfill. ⦁Q: Will a state SWMP permit need to be provided or is it covered under existing permits? A: Covered under the existing permit. ⦁Q: The subgrade prep specification calls for 12” compacted material. Does this need to be done knowing that we will be in shale? A: Exposed shale at the design subgrade is acceptable as long as the surface is stable and meets proof roll requirements. ⦁Q: Is it anticipated that the working layer above the fabric will be made out of onsite material that is excavated from the hole after some processing? A: Top size of that material is 2 inches; if excess soil meeting that spec comes out of the excavation, you can use that material ⦁Q: If there is not enough suitable material for the working layer how will that be handled? A: We believe that there will be plenty of suitable material for the operations layer. If by some chance that there is not enough material, we will work with the contractor at that time to find a solution. ⦁Q: What is the water source at the Fairgrounds(fire hydrant, ditch)? Can an overhead fill tank be installed at the source? A: Ditch Water. An overhead fill tank could be installed but there will need to be access for Eagle County vehicles to also use the water source. ⦁Q: Can you identify the dump site for excess material on the plans? A: Excess material from excavation (soil and shale) will be stockpiled at the north end of the landfill near the Construction and Demolition Diversion site. ⦁Q: What are the requirements for placement of material at the dump site(if any)? A: The contractor will need to smoothly grade the material and provide seed/mulch and silt fencing if that material will sit for quite some time. ⦁Q:Can you define “boulders” for the unit price item? What size would be paid as boulders? Does this include large pieces of shale, etc? A:We do not anticipate boulder encounters. If, in the unlikely event boulders are encountered, we would determine a fair cost for the contractor to handle them. Boulder pricing 2 DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D does not include large pieces of shale. The cost for shale excavation should take into account excavation costs for that material. ⦁Q:There is a specification for pipe/culvert, but I do not see any on the plans. Is there any pipe to be installed as part of this project? A:We’ll have to install a culvert for the access road into the cell to cross the drainage swale in the southeast corner of Mod 9A. It will be maybe 30 feet long to span the future access road into the cell, depending on how wide the access road will be. We did a 36 inch diameter culvert for the LHP project; that will work here. ⦁Q:You are looking for just a Proof of Bonding Capability letter or a bid bond? A:Proof of Ability to Secure Required Bonding letter. ⦁Q:Do we have any knowledge on projected lead times for the Shelby Tube tests? A:Usually, they take about 2 weeks to run; however, as soon as an area is complete, we will send them to the lab. We won’t wait until the end of the clay liner construction to send them all in at once. Three Shelby tube samples are required ሺone every 2.5acresሻ so we’ll obtain them as soon as a 2.5 acre area of liner is complete. Looking at previous test results from cell construction, it looks like there shouldn’t be any issues with getting acceptable hydraulic conductivity results, but of course we still need the testing done. ⦁Q:Would we be operating underneath the landfills SWMP? A:Yes. ⦁Q: Can you clarify what is necessary for the sewing/welding of the geotextile seams? A: Adjacent panels of geotextile need to be continuously welded or sewn. Typically, welding of geotextile is accomplished with a hot air leister gun with a flat nozzle (confirm with geotextile manufacturer or supplier) while sewing is accomplished by a portable sewing machine using polypropylene thread. The method of seaming is the Contractor’s decision, but the geotextile must be continuously seamed. ⦁Q: Will the engineer furnish an auto cad design file so we can build GPS models for the work? A: Yes, the selected Contractor will receive the appropriate files. ⦁Q: If unacceptable subgrade is encountered, would you consider adding a bid item to address this? Also what type of material is the structural fill? On site suitable or imported? A: On‐site soil can be used for backfilling any unacceptable subgrade. Subgrade/structural fill is described in Section 3.0 of the CQA Plan (Jessie please confirm that there is potentially enough on‐site soil for this. They could use clay or soil excavated from the Mod 9A area). ⦁Q: Is there a cost associated with water supply from either of the two sites called out in RFP? A: There is no cost for water at the Fairgrounds. Use of the fire hydrant at the MSC 3 DocuSign Envelope ID: 7B77342F-ABB2-4023-BD98-FA730ED06A2D building in Gypsum would have to be metered. ⦁Q: Plan detail calls out erosion mat and plastic fence, there are no quantities for these items. Do we include? A: Yes, these costs should be included in the price for the East Interim Liner Termination and Stormwater Control Berm (860 linear feet). The erosion mat should extend a minimum of 6 feet up the berm and 6 feet up the east slope. ⦁Q: Do not see any piping in this project. Is this correct? A: No piping for this project. ⦁Q:Will owner consider adding a rock clause of some form to allow for the possibility of encountering shale that cannot be ripped?
