YORK, Neb. (AP) — York County commissioners have decided not to adopt zoning regulations that would have affected the Keystone XL oil pipeline.

The board voted 4-1 on Tuesday against setting any zoning regulations on underground transmission lines of any type.

Board chairman Bill Bamesberger says the county attorney advised against adopting the regulations for several reasons, including the difficulty in interpreting them and the difficulty and expense in enforcing them.

Bamesberger also says state laws on siting and reclamation would pre-empt the proposed county regulations.
