NEW YORK, Sept 16 (Reuters) - Plains All American's

crude oil pipelines linking the Permian shale basin to the

Corpus Christi export hub are facing quality issues related to

high mercaptans, or naturally-occurring sulfur compounds,

according to sources familiar with the matter and a notice seen

by Reuters.

Plains in recent days has sent notices to shippers that it

will begin charging a half a dollar fee on every barrel that

fails to meet mercaptan specifications on some of its pipelines

in the Gulf Coast region, according to a notice to shippers seen

by Reuters and two of the sources.

Plains did not immediately respond to a request for comment.
