SECTION 2 FORMER BAGGING PLANT INTERIM REMEDIAL ACTION <br /> implementation of this interim remedial action,the damage will be assessed to determine the appropriate course <br /> of action,which will be to repair or replace the well. <br /> 2.2.4 Final Grading <br /> After soil amendment and slip plowing,the former bagging plant area soil amendment and tree replanting area <br /> will be graded and disked or rototilled.The primary purposes of grading and disking or rototilling are to flatten out <br /> surface soil disturbed during slip plowing, promote drainage to minimize pooling during precipitation events,and <br /> incorporate any amendments remaining on the ground surface. <br /> 2.2.5 Tree Planting <br /> After final grading, approximately 315 trees will be planted in the former bagging plant area treatment area.A mix <br /> of sycamore(Platanus acerifolia),fruitless mulberry(Morus alba),and black locust(Robinia pseudoacacia)will be <br /> planted. Other tree species may be planted in addition to or in lieu of these species if they exhibit the desired <br /> characteristics (that is, hardiness,fast growth,deep rooting, high moisture use,easy maintenance, and resistance <br /> to diseases and insects,especially moth infestation).The trees will be planted in spring 2014,when trees are <br /> dormant. Before trees are planted,a limited number of soil samples will be collected from the treatment area at <br /> depths of 0 to 2,2 to 4, and 4 to 6 feet bgs to evaluate soil pH, buffer pH, base saturation, plant-available <br /> phosphorus,and exchangeable aluminum. More samples will be collected from 0 to 2 feet bgs than from ower <br /> depths.The analytical results for these samples will be used to adjust the tree planting method, incorporate <br /> additional amendments during tree planting,or both. <br /> During tree planting,compost will be mixed with the soil before backfilling around the roots. After the trees, wv <br /> planted,the drip irrigation in the treatment area will be replaced. <br /> 2.2.6 Investigation-Derived Waste <br /> Because the treatment area will be graded after soil amendment and slip plowing, it is not anticipated ttuw r. <br /> excess soil will be generated. Decontamination water will be discharged in the planted portion of the former <br /> bagging plant area. <br /> RDD/131490W1(CM5152.DOCA) 2-3 <br /> ES052913233837 <br />
