Problems/Comments
High-level alarm and block valve failed while fueling a fire pump day tank. Overfill resulted in diesel spill of 200 gallons on 6/6/99 near middle of pad. Excavation of about 80yd of contaminated soil 6/17/99 together with soil tests for DRO/BTEX delineated the spill area. DRO and BTEX detected in one of 5 samples. Diesel contaminated soil removed is in a lined pit awaiting thermal remediation. As of 7/12/99 excavation was open waiting for ADEC determination. Some diesel contamination (5yd) remains under Skid 605 and removal threatens structure. Spill number 99399915702 PERP file number 300.02.080
