124`h Estates-TR to Anplication 4 July 9 2Q02 <br />of the reclamation bond dedicated to installation of that section of liner may be returned. Although the <br />Applicant is not eligible for the 20 percent bonding option at this time, a plan and specification for <br />installation of the liner has been provided in the Ground report. In order to be eligible for 20 percent <br />bonding following installation of the liner or sections of the liner, the Applicant's proposal must be <br />supplemented as follows: <br />1. A Construction Quality Assurance (CQA) Plan must be incorporated as an enforceable component of the <br />permit. This necessity is recognized on page 6 of the Ground report where it is stated that: <br />The Geotechnical Engineer should observe the exposed excavation surface prior to the placement of <br />fill, and observe earthwork operations and test the soils. Additional hydraulic conductivity tests <br />should be performed of the material as placed. <br />The CQA program is developed to assure that the construction of the soil components are in compliance <br />with the project specifications and to demonstrate achievement of the construction regulatory <br />requirements. The CQA monitor is the firm or individual responsible for performing the quality <br />assurance tasks. The specific responsibilities of the CQA monitor include: <br />a. review the drawings, specifications, and related guidance documents; <br />b. observe excavation activities and backfilling operations; <br />c. obtain preconstruction and construction samples and perform material evaluation testing as required; <br />d. monitor and document material placement, including soil type, clod and particle size, loose lift <br />thickness, moisture conditioning process, compaction equipment and methods, number of passes with <br />compactors, uniformity of compaction coverage, compacted lift thickness, bonding of lifts and in- <br />place moisture content and dry density as required by the specifications; <br />e. assure that testing equipment used and tests performed are conducted according to specifications and <br />industry standards; <br />f. document and report test results; <br />g. report any deficiencies in the construction and how they are resolved; <br />h. prepaze a construction certification report describing the construction, any deviations from the <br />specifications or drawings and details (with reasons and resolutions), field and laboratory test data <br />and results, and will include professional certification that construction was completed in accordance <br />with the plans and specifications. <br />The following table is an example testing protocol for a clay liner project. <br />
