TC has replaced cover material and topsoil on the face of the second <br />bench of the CRDA expansion area. According to the permit, TC is required to place four feet of cover material <br />on top of the waste material. This material should consist of 2.5 feet of suitable co ver and 1.5 feet of topsoil. <br />Three holes were dug during the inspection on the face of the second bench to verify the required amount of cover <br />material has been placed on the face of the waste pile. The first hole was on the west side of the face of the second <br />bench about a quarter of the way up on the bench. Four feet of cover was placed on top of the waste of which 22 <br />inches of material was topsoil. The second hole was located near the center of the second bench about halfway up <br />the face of the bench. Four feet of cover has been placed at this location, of which 26 inches was topsoil. The <br />third hole was located on the east side of the second bench about three quarters up the face of the bench. Four feet <br />of cover material was placed at this location of which 24 inches consisted of topsoil. The cover material consisted <br />of very dense clay. According to Mr. Watterson, TC intends to hydro -seed the second bench within the week. <br /> <br />Waste material has been windrowed on top of the second bench. It does not appear TC has expanded the <br />underdrain since the last inspection. Topsoil appears to have been excavated from the original topsoil stockpile <br />and either transported to the new topsoil stockpile or used to reclaim the second bench. During the inspection, a <br />contractor was constructing the side drainage adjacent to the face of the second bench. Rip -rap was being placed <br />in the drainage. <br />
