(c) Credit where crude oil returned to pipeline Under regulations prescribed by the Secretary, if an operator of a United States refinery—

(1) removes crude oil from a pipeline, and

(2) returns a portion of such crude oil into a stream of other crude oil in the same pipeline,

Any crude oil so returned shall be treated for purposes of this subchapter as crude oil on which no tax has been imposed by section 4611.

If any transfer is not made by reason of the preceding sentence, such transfer shall be made as soon as permitted under such sentence.

(4) No carryback No portion of the unused business credit for any taxable year which is attributable to the credit determined under this subsection may be carried to a taxable year beginning on or before the date of the enactment of this paragraph.
