C. Disposal
1. Collect, contain and dispose of all un-salvageable tank products and sludge off the Site for offsite disposal.
D. All equipment used in draining and ventilating the tanks shall be properly grounded to prevent electrostatic discharge hazards.
3.4 INERTING

If tank is to be cleaned in-place, excavate and remove soil only as required to gain access to the tank and safely perform cleaning operations.
E. Excavate as necessary to remove tank, piping, and ancillary equipment. Install sheeting, bracing, or shoring if required.
F. Implement measures as appropriate to secure open excavations during any period when tank excavations remain open. Backfill the excavations as soon as possible after tank and contaminated soil removals have been completed and confirmation samples have been taken.
G. Implement measures as appropriate to divert surface water or runoff around excavations to prevent water from directly entering into open excavations.
3.6 REMOVAL OF PIPING, ANCILLARY EQUIPMENT, AND TANK
A. Disconnect all piping and ancillary equipment from the tank. Remove all piping and conduit associated with tank to maximum extent possible. Cap all tank ancillary equipment and piping connections, except those connections necessary to inert the tanks within the excavation zone. The piping exterior and ancillary equipment shall be cleaned to remove all soil and inspected for signs of corrosion and leakage. Contaminated soil and/or groundwater is not expected.
