HARRISBURG, Pa. (WHTM) – There are more headaches for people living along the route of a natural gas pipeline.

Letters threatening liens went out to about 250 property owners along the path of the Atlantic Sunrise pipeline. A subcontractor, Ohio Machinery, claims it’s owed more than $4 million.

Similar letters were sent last month on behalf of a Michigan construction company. Williams Partners, the pipeline owner, says that matter has been resolved.

The pipeline’s route includes parts of Lebanon and Lancaster counties.
