A court ruling has given farm fertilizer dealers a reprieve from a federal policy change that some say would unfairly burden the industry.

The Occupational Safety and Health Administration policy change announced last year would regulate retail dealers of farm fertilizer such as anhydrous ammonia under the same standards as manufacturers. It came after a deadly explosion at a Texas plant in 2013.

The Agricultural Retailers Association and The Fertilizer Institute say the change would affect 3,800 fertilizer retailers nationwide, costing them more than $100 million. The two organizations sued a year ago.

The change was to take effect this coming Saturday. But a federal appeals court has ruled that OSHA can't implement it without going through a formal rule-making process.
