OSHA and the Mining Safety and Health Administration (MSHA) will be among the agencies affected by an executive order signed by President Donald Trump yesterday that requires federal agencies that want to enact a new regulation to eliminate two existing regulations.

The “one in, two out” plan is intended to reduce regulatory burdens on U.S. companies, especially small businesses. The order, which comes amid a temporary regulatory freeze issued by the White House, order does not apply to military or national security agencies.
