SOIL __ ^ (U*a c&r*****"" , / HOECHST CELANESE CORPORATION izJtf /VVdL a- Cww~<- TECHNICAL CENTER ^jiM^Tc^Pus Christ!, Texas From: To: R. A. OPERSTENY DISTRIBUTION RAO-252-90 December 14,1990 Subj: Draft of Contractor Safety Procedures for Excavations of Possible Contaminated Soil Attached is a modified draft of procedures that were used for the de-watering of HCTC's surface impoundments (ponds) last year. An early version had been generated by Jones and Neuse, our current environmental consultant, for specific cases involving EPA classified hazardous waste. I have adapted these procedures to allow general use for modifications in our pilot plant areas where contaminated soil has been found. Footing excavation for the Mid-Scale Process Units/Pharmaceutical Intermediates, for example, will require closure procedures as described in the Pilot Plant Area Closure Plan, which calls for appropriate safety procedures, in addition to a 30-day advanced notice to the Texas^Water Commission-. Mundy, our on-site contractor is currently reviewing their capabilities and training for this work * sQ&S Other situations, where prior sampling has indicated waste or soil to cabe non-hazardous, may allow less extensive actions for handling and disposal, and should be reviewed by the ESHA department. Please review the attached and return comments to me or Andy Savage. Distribution: Arnold, D. D. Atkins, B. Butts, S. K. Cooper, C. E. Hartman, L. W. Helmer, W. Kenesson, T. M . Mancias, J. B.
