Tijuana River cleanup efforts led by the federal government are suddenly in limbo after the Trump administration announced it will not re-sign the United States-Mexico-Canada Agreement. The president’s decision now triggers an annual review of the trade deal, and San Diego leaders are now arguing that any renegotiated agreement should include stronger, enforceable requirements for Mexico and the federal government to address decades of sewage and toxic pollution flowing through the Tijuana River into California. … In 2020, the USMCA included a $300 million U.S. commitment to find and develop infrastructure solutions for the ongoing, decades-long, river crisis. … But now, officials say there is an opportunity to require more than was previously laid out in the original USMC Agreement.
