				surface water, during the active life of the pile. The liner shall be:
1. A minimum of four feet above the probable
				high groundwater level as determined pursuant to
				310 CMR
				30.675;
2. Constructed of materials that have
				appropriate chemical properties and sufficient strength and thickness to
				prevent failure due to pressure gradients including static head and external
				hydrogeologic forces, physical contact with the waste or leachate to which it
				is exposed, climatic conditions, and the stress of installation. The liner
				shall also be of sufficient strength and thickness to prevent failure due to
				puncture, cracking, tearing or other physical damage from equipment used to
				place waste in or on the pile or to clean and expose the liner surface for
				inspection.
3. Placed upon a
				foundation or base capable of providing support to the liner and resistance to
				pressure gradients above and below the liner to prevent failure of the liner
				due to settlement, compression or uplift; rocks, boulders, irregularities with
				sharp edges, and all material that may damage the liner shall be removed from
				the subgrade prior to installation of the liner; and
4. Installed to cover all surrounding earth
				likely to be in contact with the waste or leachate.
