1.1 本规范规定了确定某些垃圾填埋场日覆盖材料性能的程序，通常称为替代日覆盖（ADC）。本规范仅适用于喷涂的泥浆或泡沫，或放置在城市固体废物填埋场（MSWLF）装置工作面上作为覆盖物的本土材料。它不适用于其他类型的垃圾填埋场，也不适用于用作ADC的土工合成材料。 1.2 本标准涉及ADC及其控制火灾和气味的能力的评估，以及盖子是否包含对人类健康和环境构成威胁的材料。 可以通过观察来评估对病媒和乱扔垃圾的控制，并通过安全程序和其他操作实践来控制清除。 1.3 美国环境保护局（EPA）根据《资源保护和回收法》D子标题颁布了法规，为城市固体废物填埋场（MSWLF）制定了标准。这些规定于1991年10月9日生效。《联邦法规40》第258节规定了这些法规的封面材料要求。 21，如下所示: （a） “除第款另有规定外( b )根据本节规定，所有MSWLF装置的所有者或运营商必须在每个操作日结束时，或在必要时更频繁地用6英寸（152.4毫米）的土料覆盖已处理的固体废物，以控制病媒、火灾、气味、乱扔垃圾和清理。” （b） “替代厚度的替代材料（不包括至少6英寸（152.4毫米）如果所有者或经营者证明替代材料和厚度可以控制病媒、火灾、气味、吹垃圾和拾荒，而不会对人类健康和环境造成威胁，则可由批准州固体废物管理局局长批准。 ” 1.3.1 这些联邦法规具有法律效力，本规范旨在定义符合这些法规所需的测试程序。 1.3.2 为了使MSWLF填埋场运营商获得ADC使用批准，运营商必须向州固体废物管理局提供性能数据。一般来说，用于获得该许可的技术包括向国家固体废物监管机构申请卫生MSWLF操作许可的修改。 注1: 制造商将提供其产品的性能数据。 1.3.3 对标准实践中描述的评估技术感兴趣的各方应包括MSWLF运营商、工程公司、地方、州和联邦固体废物监管机构，以及ADC材料的制造商和供应商。 1.4 单位- 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification defines procedures for determining the performance of certain landfill daily cover materials generally described as an alternative daily cover (ADC). This specification applies only to slurries or foams that are spray applied, or indigenous materials that are placed onto the working face of a municipal solid waste landfill (MSWLF) unit as a cover. It is not applicable to other types of landfills nor geosynthetics used as an ADC. 1.2 This standard addresses the evaluation of an ADC and its ability to control fires and odors and whether or not the cover contains materials that present a threat to human health and the environment. The control of disease vectors and blowing litter can be evaluated by observation, and scavenging is controlled by security procedures and other operating practices. 1.3 The U.S. Environmental Protection Agency (EPA) promulgated regulations under the Resource Conservation and Recovery Act, Subtitle D, which establish criteria for municipal solid waste landfills (MSWLF). These regulations became effective October 9, 1991. The cover material requirements of these regulations are set forth in 40 Code of Federal Regulations, Section 258.21 as follows: (a) “Except as provided in paragraph ( b ) of this section, the owners or operators of all MSWLF units must cover disposed solid waste with 6 in. (152.4 mm) of earthen material at the end of each operating day, or at more frequent intervals if necessary, to control disease vectors, fires, odors, blowing litter, and scavenging.” (b) “Alternative materials of an alternative thickness (other than at least 6 in. (152.4 mm) of earthen material) may be approved by the Director of the Solid Waste Regulatory Agency of an approved State if the owner or operator demonstrates that the alternative material and thickness control disease vectors, fires, odors, blowing litter, and scavenging without presenting a threat to human health and the environment.” 1.3.1 These federal regulations have the force of the law, and it is the purpose of this specification to define the test procedures necessary to comply with these regulations. 1.3.2 In order for a MSWLF landfill operator to obtain approval for use of an ADC, the operator must supply performance data to the state Solid Waste Regulatory Agency. In general, the technique used to obtain this permission involves applying to the state Solid Waste Regulatory agency for a sanitary MSWLF operating permit modification. Note 1: Manufacturers will provide performance data for their product. 1.3.3 Parties interested in the evaluation technology described in the Standard Practice should include MSWLF operators, engineering firms, local, state, and federal Solid Waste Regulatory Agencies, and manufacturers and vendors of ADC materials. 1.4 Units— The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
