Manual of Procedures and Criteria for Inspecting the Installation of Flexible Membrane Liners in Hazardous Waste Facilities

摘要

Under the Hazardous and Solid Waste Amendments (HSWA) of 1984, certain landfills and surface impoundments are required to assure proper containment of wastes by use of liner systems. Proper installation of the flexible membrane liner (FML) must be followed to ensure containment of wastes. The manual is intended to assist an inspector in performing all aspects of a proper FML installation inspection. Four types of FMLs are discussed in the manual: PVC, CSPE, CPE, and HDPE. The manual addresses seven installation operations. These operations include unloading and storage of FML, preparation and maintenance of supporting surface placement of FML on the supporting surface, seaming operations, anchoring and sealing, testing, and covering the FML.
