Materials and installation method to be reviewed by the testing engineer and approved by the Engineer. III. Synthetic Liner B. Materials and installation method to be reviewed by the testing engineer and approved by the Engineer APP BY LAKE LINER NOTE (SHOULD NOT BE REQUIRED FOR EXISTING PONDS) In order to minimize water level fluctuations within the lake area(s), it may be necessary to construct a liner to seal the more permeable sandy clays and sand seams which may be present on site. Acceptable liners are as follows: I. Natural Clay Liner A. Laboratory testing shall be performed on the designated liner material to determine the optimum liner compaction criteria. Subsequent to determining this compaction criteria, permeability testing shall be performed on remolded samples, compacted to this standard. Laboratory testing shall be performed at least one (1) month prior to initiating lining activities. B. The contractor shall identify and retain the engineer- approved liner material for use on sealing the side slopes and bottom of the lake(s). The optimum natural liner material shall not be used for other portions of site work prior to verification that adequate resources are available and have been stockpiled. It is important that the stockpiled soils be stored in as small an area as possible to retain natural moisture. The contractor should anticipate that additional soil work may be required to bring the liner material to required uniform moisture level. C. A representative of the testing engineer shall be present for inspection of the base and side slopes of the lake(s) prior to and during compaction of the liner materials. D. The clay lining material, approved by the testing engineer, shall be compacted to a minimum of 12 inches thick on the upper two thirds of the side slopes and 18 inches on the lower one third. A compacted minimum of 18 to 24 inches approved lining material shall be placed across the base of the lake. E. The clay liner material shall be regularly sampled and tested for conformance to the moisture and Atterberg limits established for the approved liner material(s). Field density and moisture testing shall also be performed frequently during construction to establish a correlation between density and field permeability. It is imperative that moisture levels be maintained over optimum as determined in laboratory testing. Only by maintaining this condition will it be possible to approach the zero voids condition and maximize natural liner capabilities. Off -site sources for day liner material may be used with approval by the Owner's representative and one -site testing engineer. F. Compaction of the natural liner shall be performed by equipment operating up and down the slope. Engineered natural clay liners shall not be compacted by equipment operating around the slopes on or near the same elevation. It is important that hydration of the clay liners takes place after installation is complete. This is typically accomplished by natural rainfall or by application of fresh water at the rate of one quarter gallon per square foot for at least 72 hours. This recommended rate of hydration will help prevent shrinkage and cracking of the clay liner and maintain its integrity. CID sor 1� C/3 1� 1� t) O CV Q? J 4.
