(CNN) The Environmental Protection Agency "exceeded" its goals in cutting back environmental regulations during the first two years of the Trump administration, according to an internal watchdog report.

The EPA's inspector general evaluated how the agency responded to an executive order from President Donald Trump issued in January 2017 mandating federal agencies control costs by cutting regulations. The EO asked that for every one regulation an agency issued, two regulations be cut.

The EPA cut 26 regulations, saving the agency more than $96 million, and created four new regulations -- far more than the 2-to-1 ratio the White House had requested, according to the report. The agency saved roughly $6 million more than the Office of Management and budget requested.

In the administration's first year, "the EPA had the highest number of deregulatory actions of any federal agency," according to the report.

These actions include rollbacks of environmental regulations that govern water, air and greenhouse gas emission levels.
