EPA took a fresh step in its unrelenting deregulatory campaign with a proposal to toss stricter standards on releases of a powerful carcinogen from plants that sterilize medical equipment.

As grounds, EPA said that the strengthened regulations resulted from a review that was illegal under the Clean Air Act. In a news release, Administrator Lee Zeldin also cited concerns that the stronger rules could affect health care by cutting into supplies of safely sterilized medical equipment.
