A split is emerging within Trump’s base as health activists accuse Mr. Zeldin of leading the agency to prioritize chemical industry interests over public health.
Lee Zeldin, the E.P.A. administrator, appeared with Health Secretary Robert F. Kennedy Jr. in Salt Lake City earlier this year. Recently, Mr. Zeldin has gone on a charm offensive.
A draft memo from the E.P.A. assumes a safe threshold exists for formaldehyde, upending earlier findings that there is no safe level of exposure to the carcinogen.
Between one to five billion pounds of formaldehyde is produced in the United States each year for a wide range of industries and products, including composite wood and other building materials, plastics, pesticides and even some hair straightening treatments.
