• agreement for the Phase II monitoring plan was subsequently submitted to the Division on July 6, <br />1987 (letter, G. Wendt to P. O'Connor) and approved by the Division on August 4, 1987 (letter P. <br />O'Connor to J. Lunan). <br />Laboratory parameters included paste pH, ammonium nitrogen, sodium adsorption ratio, and Acid <br />base potential. Phase II SAR analyses were confined to Sites 881 E and 882E since elevated SAR <br />values were identified only at Site 872E during Phase I drilling. <br />Analytical Procedures - Phase I and Phase II <br />At the lab (InterMountain Lab, Farmington, New Mexico), chip samples and cores were air dried, <br />split, and composited according to lithologic and stratigraphic sequence, crushed to pass a 10 mesh <br />sieve, and bagged for storage. Prior to splitting and crushing intact cores, foreign material attached <br />to the outside of the core was removed. Overburden chip samples from Phase I Site 871 E were <br />collected from 2-foot vertical increments. Adjacent 2-foot chip samples of similar strata were <br />composited into 4-and 6-foot vertical increments prior to laboratory analysis. Phase II overburden <br />chip samples were composited by similar strata while geologic descriptions were prepared during <br />• field sampling. All samples from the three Phase 1 cores and three Phase II combination core/bore <br />holes were chemically and physically analyzed at InterMountain Laboratory using the procedures <br />listed in Table 2.04.6-2. The parameter and procedure list was developed by Peabody's soil <br />scienfrst (Gary Wendt) in consultation with the Division's reclamation specialists (Peter O'Connor <br />and Steve Renner). Extensive reference was made to the Division's 1982 Water Quality and <br />Overburden Geochemistry Guideline. <br />• Revised 27 Aug 2002 20 <br />
