(AP) — A federal agency is proposing nearly $133,000 in fines for a Hastings cold storage plant, alleging more than a dozen safety violations.

The U.S. Department of Labor’s Occupational Safety and Health Administration says in a news release that workers were exposed to anhydrous ammonia at the Nebraska Cold Storage Inc. plant.

OSHA inspected the plant in March. The agency says some of the violations involve the failure to correct deficiencies in equipment and to document responses to violations found in a 2010 safety audit. The agency says 12 of 22 violations found three years ago remain uncorrected.

The plant manager didn’t immediately return a call Tuesday from The Associated Press.

The company can contest the citations and proposed penalties before the independent Occupational Safety and Health Review Commission.
