# §265.194. General operating requirements.

- (a) Hazardous wastes or treatment reagents must not be placed in a tank system if they could cause the tank, its ancillary equipment, or the secondary containment system to rupture, leak, corrode, or otherwise fail.
- (b) The owner or operator must use appropriate controls and practices to prevent spills and overflows from tank or secondary containment systems. These include at a minimum:
  - (1) Spill prevention controls (e.g., check valves, dry disconnect couplings);
  - (2) Overfill prevention controls (e.g., level sensing devices, high level alarms, automatic feed cutoff, or bypass to a standby tank); and
  - (3) Maintenance of sufficient freeboard in uncovered tanks to prevent overtopping by wave or wind action or by precipitation.
- (c) The owner or operator must comply with the requirements of [§ 265.196](/cfr/40/265.196.md) if a leak or spill occurs in the tank system.
