【正文】 (x) the field crew foreman of the liner installer must have a documented minimum qualification of successful installation experience of at least 50 acres of previous landfill or parable geosynthetic systems, on a minimum of five different projects.(3) Certification requirements. The project engineer must include in the construction certification report a discussion of the approved data resulting from the quality assurance and quality control testing as required in this paragraph. The results of all testing must be included in the construction certification report including documentation of any failed test results, and descriptions of the procedures used to correct the failed material, and statements of all retesting performed.(i) The project engineer must certify the quality control testing of any manufactured geosynthetic materials ensuring that the material and the finished product meet the requirements of the approved engineering plans, reports, and specifications. Before installing any geosynthetic material, the following information must be available to the project engineer for approval:(a) origin and identification of the raw materials used to manufacture the geosynthetic material。(ix) field seaming is prohibited when either air or sheet temperature is below 32176。(v) the anchor trench must be excavated to the length and width prescribed on the approved design drawings。s remendations. The project engineer must ensure that the geomembrane installation, at a minimum, must conform with the following:(i) the geomembrane in both the primary and secondary posite liner must have a minimum thickness of 60 mils。 one laboratory permeability test using a triaxial cell with backpressure for every 5,000 cubic yards of material placed。s side slope if a leachate barrier system is designed and constructed to minimize leachate migration into the existing landfill.(1) Materials required. The landfill subgrade material must be free of organic material (other than small roots of trees, shrubs, grasses, etc.) and consist of onsite soils, or any select fill, if approved by the department.(2) Construction requirements. The landfill subgrade must be graded in accordance with the requirements of the approved engineering plans, report, and specifications to have a minimum postsettlement slope of two percent. The material must be sufficiently dry and structurally sound to ensure that the first lift, and all succeeding lifts of soil placed over the landfill subgrade, can be adequately pacted to the design requirements and assure stability of the landfill.(3) Certification requirements. At a minimum, the subgrade surface must be inspected in accordance with the following requirements:(i) before any material is placed over the subgrade, the project engineer must visually inspect the exposed surface to evaluate the suitability of the subgrade and to ensure that the surface is properly pacted, smooth, and uniform, and that elevations are consistent with the department approved plans。 Corrective measures report.2 167。 Landfill gas recovery facilities.contents page.]1 Contents:Sec.

Financial assurance criteria.s performance will be consistent with that which is expected from the application of this Part. In such cases, the department will require additional groundwater drainage systems to ensure that the seasonal high groundwater table does not e in contact with the lowermost portion of the landfill liner during construction, and until such time that the hydrostatic pressures are equalized by weight of the liner system and/or waste.(e) Bedrock separation. A minimum of 10 feet vertical separation must be maintained between the base of the constructed liner and bedrock. The nature of the materials making up this separation, whether natural or backfilled, is subject to department approval.(f) Liner system description. The minimum liner requirement for all landfills accepting mixed solid waste must consist of the following:(1) On all bottom areas where the landfill slope is less than or equal to 25 percent, the liner system must consist of a double posite liner separated by a secondary leachate collection and removal system.(2) On all side slope areas where the landfill slope is greater than 25 percent the liner system need only consist of a primary leachate collection and removal system above the uppermost geomembrane liner and a lower posite liner separated by a secondary leachate collection and removal system.(3) A posite liner must consist of two ponents, an upper geomembrane liner placed directly above a low permeability soil layer meeting the requirements specified in subdivisions (j) and (k) of this section. Each posite liner is considered a single liner.(4) The double posite liner system must include a primary leachate collection and removal system consisting of a 24inch granular soil layer with a leachate collection pipe network. The primary leachate co
