Claim 12

An assembly as in claim 1 further comprising a viewing structure mounted on said container and extending along at least a portion of the length thereof and disposed to allow visual observation of the contents of said container at a disposition corresponding to the surface junction between oil and water within the container.

Claim 13

An assembly as in claim 10 further comprising a filter means attached to said discharge means for filtering pollutants from liquid issuing said discharge means.

Claim 14
