【正文】 ner and subgrade are of dissimilar materials. Any succeeding lifts of the soil ponent of the lining system may be reduced in thickness, depending upon the paction equipment used.(iii) The moisture content of the soil ponent of the liner system must be maintained, within the range identified in the moisturedensity permeability relation developed in accordance with paragraph (3) of this subdivision, before and during paction of the soil lift to ensure that the remolded lift attains a maximum in situ permeability as required. The density after paction must be within the range identified in the moisturedensitypermeability relation developed in accordance with paragraph (3) of this subdivision to ensure that the remolded lift attains a maximum in situ permeability as required.(3) Certification requirements. The project engineer must include in the construction certification report a discussion of all quality assurance and quality control testing required in this paragraph. The certification report must address all measures taken to prevent or remedy soil liner damage from either desiccation or freezing, both during and after construction. The testing procedures and protocols must be submitted prior to construction in accordance with section of this Subpart and approved by the department. The results of all testing must be included in the construction certification report including documentation of any failed test results, descriptions of the procedures used to correct the improperly installed material, and statements of all retesting performed in accordance with the following requirements:(i) The project engineer must certify the quality control testing of any soil liner materials to ensure that the specified material meets the permeability requirements of paragraph (1) of this subdivision and the approved engineering plans, reports, and specifications. Before and during construction of the soil ponent of the liner system, the following information must be approved by the project engineer: one analysis of soil particle size for every 2,500 cubic yards of soil liner materials placed。 Landfill reclamation.

A plete list of Subparts in this regulation appears in the With repeal of existing Subpart 9 and promulgation of new Subpart 9: State Assistance for Municipal Landfill Closure ProjectsRevised Effective January 25, 1992。 with adoption of amendments to existing Subpart 9: State Assistance for Municipal Landfill Closure ProjectsRevised Effective January 14, 1995。 Landfill construction requirements. Landfill construction requirements.Except as otherwise expressly provided in section of this Subpart, all new landfills and lateral and vertical expansions of existing landfills regulated under this Subpart must conform to the requirements set forth in this section.(a) Horizontal separation requirements.(1) The minimum horizontal separation between deposited solid waste in the landfill and the property line must be 100 feet.(2) The required horizontal separation between deposited solid waste and any surface waters must be adequate to preclude contravention of State surface water standards in the surface water body, or flooding of the landfill from the surface water body. In no case can solid waste be deposited closer than 100 feet from the mean high water elevation of any surface waters. The department may require greater horizontal separation between solid waste and surface waters when those surface waters are actively used as sources of municipal water supply.(b) Survey control. One permanent survey benchmark of known elevation measured from a . Geological Survey benchmark must be established and maintained for each 25 acres of developed landfill, or part thereof, at the site. This benchmark must be the reference point for establishing vertical elevation control.(c) Location coordinates. The New York Transverse Mercator (NYTM) coordinates must be established. Horizontal control must be established and one of its points must be the benchmark of known NYTM coordinates.(d) Groundwater separation. A minimum separation of five feet must be maintained between the base of the constructed liner system and the seasonal high groundwater elevation. At sites where perched water is encountered the department will determine with respect to groundwater separation distances whether separation distances will be measured from the perched zone or the nonperched water table. The nature of the materials making up this separation, whether natural or backfilled, is subject to department approval. This minimum five feet separation requirement may be reduced or waived upon demonstration of selection of a suitable landfill site, as defined under section (a) of this Subpart, and upon demonstration that pliance with this provision would impose an unreasonable economic, technological, or safety burden。 one moisture content test for every 1,000 cubic yards of material placed。(vi) field seams should be oriented parallel to the line of maximum slope, ., oriented along, not across the slope. In corners and irregularly shaped locations, the number of field seams should be minimized. No horizontal seam should be less than five feet from the toe of slope toward the inside of the cell。(b) copies of quality control certificates issued by the producer of the raw materials used to manufacture the geosynthetic material, which at a minimum must include reports of tests conducted to verify material quality, including specific gravity, melt flow index, percent carbon black, and carbon dispersion using methods acceptable to the department。 all test locations must be appropriately documented.(2) The project engineer must approve the sample size to be taken. The sample size must be large enough to perform the required testing.(3) An independent laboratory acceptable to the department mu
