Background:
At the time of your inspection of August 18-20, 1988, approximately 65,000 cubic feet of excavated material containing detectable concentrations of byproduct material was configured in approximately 150 piles and locahd in a fenced-in area at the east end of the lower parking lot. The piles of material were placed on top of a layer of polyethylene film and were covered with several pieces of polyetnylene. A double layer of polyethylene was also attached to the fence frame. Enerience proved that expoVJre to wind an'J/or rain Caused the sheets of polyethylene placed on top of the piles of material to move despite repeated efforts to secure the polyethylenr. Cause: Both the configuration of the material (multiple piles) and the lack of a single sheet of pclyethylene large enough to cover all the piles contributed to the ineffectiveness of the covering. Actions Taken: As interim action, periodic inspection and maintenance of the dirt pile rover was irnplemented on August 31, 1988, A single sheet of polyethylene was procured to cover the material. The tops of the piles of material were flattened to create a single mound with the exception of a small portion of the ma+erial consisting primarily of large boulders and concrete chunks. The mound and the plie of boulders and concrete were covered with polyethylene hnd secured with tires to provide a more effective barrier against wind and rain erosion. Page 1 of 2
's ATTACHMENT o (Continued) l Continuing Actions: Until final disposition of the material is achieved: periodic visual inspection of the material covering (currently being conducted daily, Honday through Friday) and maintenance as appropriate will continue, and in-situ measurements and soil samples will be obtained around the l fence perimeter and analyzed on a yearly basis to reconfirm the boundary of the material.
