Members of San Diego’s congressional delegation Monday called on the U.S. Small Business Administration to continue to support small businesses impacted by Tijuana River Valley pollution. Reps. Juan Vargas, Scott Peters, Sara Jacobs, all D-San Diego, and Rep. Mike Levin, D-San Juan Capistrano, also asked for additional information from SBA Administrator Kelly Loeffler on what steps the SBA has already taken. “As South San Diego County’s beaches continue to be impacted by untreated wastewater, sediment and trash from the Tijuana River, South Bay businesses have suffered economically,” the lawmakers wrote in a joint letter. “While we continue to work with our Mexican counterparts to address the causes of the pollution, it’s important that we also take steps to support local small businesses impacted by the pollution and the consumers who rely on them.”
