Key Agricultural Services, I nc. <br />114 Shady Lane - Macomb, IL 61455 - (309) 833 -1313 <br />pits were excavated in the Substitute Subsoil Redistribution Area during the December sampling <br />event. A total of approximately 1,658 pounds of soil was removed from the site for analysis and <br />testing. <br />Although OSM had initially requested to take split samples (which were not required by TR -61), <br />because of conditions in the field it was decided instead and at OSM's request that Key -Ag <br />would prepare duplicate samples to be submitted to a laboratory of OSM's choosing. In all, a <br />total of 293 soil samples were collected from the soil resource stockpiles, undisturbed native soil <br />and substitute subsoil redistribution area. <br />The purpose of TR -62 is to document and explain the field changes to the sampling plan <br />originally approved in TR -61 that occurred during the December 12 through December 14 <br />sampling. As was discussed in TR-61, field changes were anticipated during this intensive <br />sampling effort and TR-61 provided that personnel in the field could alter the sampling locations <br />depending upon conditions encountered in the field. <br />Field Work Completed <br />The following field activity was completed during either the November or December sampling <br />efforts, as indicated below. <br />1) Description of undisturbed native soil (November); <br />2) Sampling of the soil resources stockpiles (December); <br />a. Lift A (large and small stockpiles); <br />b. Lift B; <br />c. Mixed (large and small stockpiles); <br />3) Pits to identify potential coarse fragments in the soil resource stockpiles.(December); and <br />4) Description of Substitute Subsoil Redistribution Area (December). <br />The soil resource stockpiles were sampled using a direct push Geoprobe ( Geoprobe Systems, <br />Salina, Kansas) system. Soil cores were obtained in zero contamination plastic sleeves within <br />casings to ensure that the hole remained open and did not collapse. ACI Services owned and <br />operated the Geoprobe system and Key -Ag soil scientist and agronomist logged and bagged all <br />samples as they were collected. Hydrochloric acid was used during the logging of the samples to <br />determine presence or absence of carbonates within the system. All samples were visually <br />reviewed with color, effervescent, course fragments, and other notable items recorded. <br />Certain slight modifications to the TR-61 sampling plan were made in response to drilling <br />refusal. During soil sample collection of the soil resource stockpiles less than 201/9 of the boring <br />Page 2 <br />
