Contaminated soil shall be transported off-site for disposal.

F. Tank Cleaning

1. Exterior: Uncontaminated soil shall be removed from the tank exterior to eliminate soil deposition on roadways during transportation to a temporary storage area, ensure markings will adhere to the tank surface, and simplify tank cutting. Soil shall be removed using non-sparking tools. Soil removal shall be compiled on a geomembrane adjacent to the tank removal site approved by the Engineer. Uncontaminated soil removed from the tank exterior shall be recovered and used as backfill in the former tank excavation.

Cleaning shall be accomplished in a manner that eliminates the need for personnel to enter the tank to the greatest extent possible. Cleaning shall be done using specially designed tank cleaning equipment which allows the tank to be cleaned prior to cutting into sections without requiring personnel to enter the tank or, if less specialized equipment is used, the tank shall be partially dissected to overcome confined space entry hazards by removing the end walls. In either case, the cutting operation shall be accomplished using non-sparking or non-heat producing equipment.

3.5 SOIL EXAMINATION, TESTING, AND ANALYSIS

A. General: After soil excavation is complete, the excavation shall be sampled in accordance with State regulations. Samples may be obtained from the pits using a backhoe with a Shelby tube attached to the bucket. Sample preservation and analytical procedures shall conform to EPA SW-846.
