The locations may shift due to vegetations or other obstacles in the field. The purpose of the additional test pits is to: •Delineate the limit of waste on the northeast perimeter of the landfill (yellow dots on map), wherecurrently no waste was identified at the suspected limit of waste, or within the 50-foot workzone, and •Characterize the central mounded area of the landfill to delineate the depth of waste below the soilcap (blue dots on map), for grading plan considerations when designing the landfill cap. I have included a map, attached to this letter, showing the tentative locations. The map also depicts current progress of the limit of waste evaluation, provided for context and information purposes only at this time. The test pits will be back filled with soil and seeded, following procedures in the approved Limit of Waste Evaluation –Investigation Work Plan. If you have any questions or need additional information regarding this request, please contact me at (717)982-0986 or by email at Ashley.Albert@duke-energy.com.
