  • (c) in the case of an aboveground horizontal tank, they must visually inspect the walls of that tank to determine if the tank is leaking;

  • (d) in the case of underground piping, they must test that piping using the piping precision leak detection test in accordance with section 24;

  • (e) in the case of aboveground piping, they must visually inspect the walls of that piping to determine if the piping is leaking; or

  • (f) in the case of a turbine, transition, dispenser or pump sump, they must perform a static liquid media leak detection test that respects the following conditions:

    • (i) the test has a duration of at least one hour,
