The Trump administration is shaking up leadership on the International Boundary and Water Commission as it pressures Mexico to curb sewage pollution in the San Diego border region — including through a visit to the area Tuesday by EPA Administrator Lee Zeldin.
The administration has tapped Chad McIntosh, who is stepping down from his position as acting deputy administrator at EPA, to lead the International Boundary and Water Commission, a White House spokesperson said Tuesday. The federal agency is charged with upholding water treaties between the U.S. and Mexico, managing water infrastructure along the border, and ensuring water quality is maintained.
McIntosh replaced Maria-Elena Giner, the agency’s commissioner since 2021, who confirmed her resignation Monday via a post on LinkedIn. The White House did not respond to a question about why Giner was replaced.
An EPA spokesperson did not immediately say who would replace McIntosh as EPA’s second in command.
