Section 2.1 details two excavation events occurring from 1974 and 1982 likely due to obtaining soil for <br /> the construction of an earthen berm/levee on the south side of the railroad tracks between the plant and <br /> the staging area. Does PNA have information regarding the excavation activity? If there was information <br /> that has not been forwarded to the EHD please do so. <br /> 2.) Section 2.1 describes a general clean up of the site in reference to exposed inert construction debris. <br /> Does this mean there will be digging, if so, what contingency plan is there if excavation results in <br /> unearthing a column of waste? <br /> 3.) Section 4.0 states a .25 -.5 inch layer of granular bentonite clay will be utilized as the primary <br /> layer. The does not provide any information regarding the level of protection this type of cover <br /> provides. The plan doe not describe the anticipated life of the cover. <br /> 4.) Section 4 does not describe how the cover will provide adequate run off. The plan lacks a grading plan to <br /> show the flow of storm water. The plan does not include rainfall for the area or anticipated storm water run <br /> 7/11/2013 <br />
