(Tetra Tech) has prepared this Construction Quality Control/Quality Assurance Plan (CQCQAP) to support the proposed Landfill Gas/Soil Vapor Extraction/Air Injection (LFG/SVE/AI) and Treatment System at the City of Bozeman Landfill in Bozeman, Montana. The system will include installation of: 1) an equipment slab; 2) flare or thermal oxidizer; 3) gas handling system; 4) condensate holding tank; 5) air compressor; 6) six LFG extraction wells; 7) six AI wells; 8) five SVE wells; and 9) SVE vaults, AI vaults, and condensate sumps. Collectively, the construction activities are referred to as Alternative F as described in a Revised Corrective Measures Assessment Report (Tetra Tech, 2014). This CQCQAP is a companion document to the Plans, Specifications and Contract Documents for Alternative F and establishes project procedures and general responsibilities for the quality control program to ensure that the LFG/SVE/AI and Treatment System is executed in accordance with the relevant portions of the Plans and Specifications. The objectives of this CQCQAP are to: Describe the quality program and organization to be implemented so that the project is conducted in accordance with contract requirements and industry standards; Describe guidelines for inspection and documentation of activities; Provide reasonable assurance that the completed work will meet or exceed the requirements of the construction drawings and specifications; Describe how any unexpected changes or conditions that could affect the construction quality will be detected, documented, and addressed during construction. A General Contractor (GC) will be selected through a competitive bidding process and be responsible for conducting the work and providing quality control in accordance with the approved plans and specifications. Each subcontractor is also responsible for controlling the quality of his/her work to meet contract plans, specifications, and related requirements. Quality Control (QC) is the systematic implementation of a program of inspections, tests, and controls to attain the required standards of quality and to preclude problems resulting from noncompliance. Tetra Tech will provide Quality Assurance (QA) through daily monitoring and scheduled inspections to verify that contract requirements are being met. Tetra Tech's On-Site Supervisor (OSS) will be responsible for the day-to- day coordination of QA measures in the field. The OSS will assure that QA is working effectively and that the resultant construction complies with the quality requirements established by the contract. 1.1 CQCQAP ORGANIZATION This Construction Quality Control Plan is organized as follows: Section 1 — Introduction: Provides a CQCQAP quality program overview Section 2 — Project QC Organization: Presents organization and key personnel involved in the second-phase expansion, their responsibilities and authorities, and the structure of the Quality Control/Quality Assurance (QC/QA) organization Section 3 — Inspection and Verification Activities: Provides procedures for tracking construction inspection and verification activities for the contract, construction acceptance criteria, and construction audits Section 4 — Construction Deficiencies: Describes the procedures for tracking construction deficiencies from identification through acceptable corrective action Section 5 — Field Changes: Describes handling of quality plan changes to assure QC/QA objectives are met Construction Quality Control/Quality Assurance Plan LFG/SVE/AI and Treatment System 2 City of Bozeman Landfill Section 6 — Documentation: Describes procedures for project document management in a secure document filing and storage system 2.0 PROJECT QA/QC ORGANIZATION This section presents the responsibilities and authorities of key personnel involved in the construction of Alternative F, and the structure of the QC/QA organization. 2.1 RESPONSIBILITIES AND AUTHORITIES OF KEY PERSONNEL Key personnel involved in the LFG/SVE/AI and Treatment System construction and their QC/QA roles and responsibilities are described below in Section 2.1.1 and Section 2.1.2.

Construction Quality Control/Quality Assurance Plan LFG/SVE/AI and Treatment System 3 City of Bozeman Landfill 2.1.2 QA On-Site Supervisor The OSS, who shall be named at a later date, is responsible for implementation of this CQCQAP. The OSS is the Tetra Tech primary point of contact for the City of Bozeman on all construction management issues. The OSS is responsible for the overall management of activities related to the construction program, including the implementation of the CQCQAP and the health and safety program. The OSS will manage the Alternative F construction on behalf of the City of Bozeman. The OSS will provide QA and monitor the day-to-day construction QC activities performed by the GC and its subcontractors to verify compliance with the contract plans and specifications. Additionally, the OSS may be assigned management of any third party QA inspection and testing firms retained by the City of Bozeman or the GC. The OSS may designate other Tetra Tech employees as necessary to provide QA oversight. 2.1.3 QC Supervisor The GC shall designate a QC Supervisor who shall be responsible for implementing all the aspects of QC described in this plan. The QC Supervisor will be named at a later date after a GC has been selected and before construction begins. The QC Supervisor will implement the QC plans by implementing the following: Inspect all materials and equipment for conformance with technical specifications, Perform all QC tests as required by the technical specifications, Coordinate all QC activities among its subcontractors, and Submit all QC reports and other QC documentation to the OSS. The QC Supervisor may designate other GC employees as necessary to perform QC measures or reporting, including employees of its subcontractors. 3.0 INSPECTION AND VERIFICATION ACTIVITIES 3.1 GENERAL CONSTRUCTION INSPECTION AND VERIFICATION REQUIREMENTS The GC QC Supervisor and all other personnel as designated will perform the inspections and tests as prescribed in the technical specifications. QA inspection and testing will be used to verify the adequacy and effectiveness of the GC’s QC program. 3.1.1 QC Inspections The GC will establish and implement a program for inspection of activities affecting quality that will cover the entire construction site. Inspections will be performed to verify compliance with documented instructions, drawings, procedures, and specifications as required by the contract. All inspections will be documented by the contractor. A four-phase inspection program will be followed for each definable feature of the work. The four phases of inspection are: 3.1.1.1 Preparatory Inspection The QC Supervisor will perform preparatory inspections prior to beginning any work on any definable feature of the work. As part of the preparatory inspection, the QC Supervisor will: Ensure that preparatory work includes a review of contract requirements Ensure that all materials and/or equipment have been tested, submitted, and approved Construction Quality Control/Quality Assurance Plan LFG/SVE/AI and Treatment System 4 City of Bozeman Landfill Examine materials and equipment to ensure that they conform to design documents, that all materials and/or equipment are on hand, and that all monitoring and measuring equipment is properly calibrated and in proper working condition Record preparatory inspections in the QC documentation 3.1.1.2 Initial Inspection The QC Supervisor will perform an initial inspection as soon as a representative portion of the particular feature of work has been accomplished. The QC Supervisor will: Examine the quality of workmanship Review control testing for compliance with contract requirements Review dimensional aspects of the work Record initial inspections in the QC documentation 3.1.1.3 Follow-up Inspection The QC Supervisor will perform follow-up inspections daily to: Ensure continuing compliance with contract requirements Ensure continuing compliance with control testing until completion of particular feature of work Record follow-up inspections in the daily inspection report Conduct final follow-up inspections and correct test deficiencies prior to the addition of new features of work 3.1.1.4 Completion Inspection The QC Supervisor will perform a completion inspection of the work to: Develop a “punch list” of items that do not conform to the approved plans and specifications Include the punch list in the construction QC documentation Indicate the estimated date by which the deficiencies will be corrected Perform a second completion inspection after punch list items have been completed The daily inspection reports will identify inspections conducted, results of inspections, location and nature of defects found, causes for rejection, and remedial or corrective action taken or proposed. When deficiencies are discovered during the four-phase or other inspection processes, the OSS will be informed of any quality issues and the resolution. When material or performed work is found to be deficient and/or does not meet the project specifications on the basis of focused inspections, the OSS will assure deficiency correction is implemented, as discussed in Section 4. 3.1.2 QA Inspections The OSS will perform periodic testing and inspection of construction activities. These will include witnessing of the GC’s testing or performance of independent tests and inspections. At a minimum, the testing will be as described in Table 3-1. Table 3-1.

Utility Locate Ticket Active. Each Day 3.1.3 Construction Audits Tetra Tech will establish and document an auditing system to verify its own (and the GC’s) implementation of and conformance to the CQCQAP and contract technical specification requirements. The auditing system will be used to make a determination regarding the effectiveness of the QC/QA system. Audits will be performed by qualified and properly trained personnel who are familiar with the QC/QA system, auditing procedures and techniques. Selection of auditors and the conduct of audits will ensure the objectivity and impartiality of the audit process. The OSS or any designated QA personnel designated by the OSS may not be an independent auditor. The auditing system will cover all activities affecting quality for construction. The results of the audits will be documented and reported to the OSS. All non-conformance conditions identified during the audit will be re-audited to verify effectiveness of corrective actions taken by the appropriate organization. Audits will be conducted periodically during construction of Alternative F. 4.0 CONSTRUCTION DEFICIENCIES This section provides procedures for tracking construction deficiencies (noncompliance) from identification through acceptable corrective action. It defines the controls and related responsibilities and authorities for dealing with noncompliant products or services. Deficiency occurs when performed work does not meet the plans and/or specifications for the project. 4.1 CONTRACTOR QC DEFICIENCY IDENTIFICATION AND CONTROL When performed work is found deficient, a QC Supervisor (or designee) will ensure that the non-conforming work is identified and controlled to prevent unintended use or delivery. The QC Supervisor will notify the OSS of any noncompliance with any of the foregoing requirements. Minor deficiencies noted during inspection are verbally reported to the OSS and noted on the Daily Construction Report. Minor deficiencies are items that do not require significant rework or repair work to correct and will not result in significant deviations from required quality standard if corrected immediately. Control and disposition of minor deficiencies will be conducted by the QC Supervisor and do not require formal action by the OSS. Ideally, such minor deficiencies can be corrected on the Construction Quality Control/Quality Assurance Plan LFG/SVE/AI and Treatment System 6 City of Bozeman Landfill spot by agreement with the OSS. Non-conformances are major deviations from the contract requirement and/or accepted standard of quality, which must be formally documented for corrective action by the QC Supervisor and the OSS. 4.2 CONTRACTOR DEFICIENCY CORRECTION When performed work is found to be deficient and/or does not meet the project specifications, the QC Supervisor will ensure deficiency correction is implemented. The QC Supervisor will ensure that the non-conforming work is identified and controlled to prevent unintended use. The QC Supervisor is responsible for documenting the non- conformance. The GC will implement corrective actions to remedy work that is not in accordance with the drawings and specifications. The corrective actions will include removal and replacement of deficient work using methods approved by OSS. Replacement will be done in accordance with the corresponding technical specifications. Replacement will be subjected to the same scope of QC/QA inspection and testing as the original work. If the replacement work is not in accordance with the drawings and specifications, the replacement work will be removed, replaced, re-inspected, and re-tested. 4.3 PREVENTIVE ACTIONS Preventive actions are taken to eliminate the cause of a potential non-conformity. The OSS will take preventive actions as necessary to eliminate the causes of potential deficiencies so as to prevent their occurrence. 5.0 FIELD CHANGES Field changes for QC/QA will be limited to changes to this CQCQAP. Changes to construction processes or design plans and specifications are governed by the design change order procedures. 5.1 CQCQAP CHANGES The City of Bozeman, the OSS, or the QC Supervisor may initiate revisions to this CQCQAP. The CQCQAP may be revised when it becomes apparent that existing procedures or controls are inadequate or deemed to be more excessive than required to support work being produced in conformance with the specified quality requirements. Tetra Tech will notify managing contractor in writing of changes to QA or QC procedures necessitating modification to this CQCQAP. All changes are subject to City of Bozeman acceptance. 6.0 DOCUMENTATION Documentation will cover all aspects of QC/QA program activities and include Daily Construction Reports, equipment and system inspection forms, and testing checklists. 6.1 QC DAILY RECORD KEEPING Project documents will be managed through a combination of a secure document filing and storage system. Sufficient records will be prepared and maintained as work is performed to furnish documentary evidence of the quality of construction and activities affecting quality. The QC Supervisor will maintain a daily log of all QC inspections performed and subcontractor operations on a form acceptable to the OSS. The daily log will be signed by the QC Supervisor. At least one copy of each daily log will be provided to the OSS on the work day following the day of record.
