  2. that any oily surface water is cleaned out before discharge,
  3. that the collection system has a shutdown device,
  4. that tank drain valves are located and sheltered such that they can be operated in the event of fire,
  5. that drainage, including the drainage system, is carried out such that it is not obstructed by the formation of ice, foreign bodies, etc., and
  6. that the bottom of the collection system slopes towards the drainage opening.
