This specification defines procedures for determining the performance of certain landfill daily cover materials such as sprayed slurries, foams, and indigenous materials generally described as an alternative daily cover (ADC) for municipal solid waste landfills. It is not applicable to other types of landfills and to geosynthetics used as an ADC. It 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. Materials shall be tested at accredited laboratories to determine the physical properties such as potential for fire production, water vapor permeance, toxicity, and leaching potential. The control of disease vectors and blowing litter shall be evaluated by observation while scavenging shall be controlled by security procedures and other operating practices.

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 that are sprayed, 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. It does not apply to 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 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 and health practices and determine the applicability of regulatory requirements prior to use.
