The United States Section of the International Boundary and Water Commission (USIBWC) is pleased to announce Nicolas Chapa as the Area Operations Manager (AOM) to lead the San Diego Field Office where he will oversee operation of the South Bay International Wastewater Treatment Plant (SBIWTP), which treats Mexican wastewater to U.S. standards. Other duties include operation and maintenance of the Tijuana River Flood Control Project, international boundary demarcation, SBIWTP permit reporting, operation of the canyon collectors that capture stormwater and wastewater from Mexico, and coordination with the Mexican Section of the Commission on the region’s boundary and water issues.

Chapa brings more than 25 years of experience in engineering and environmental compliance in the U.S.-Mexico border region, including work as a Senior Environmental Engineer/Scientist with Brown and Caldwell and, later, Ninyo and Moore. He served as Project Manager for Transboundary Environmental Assessments for various wastewater projects in Mexican border communities, including Tijuana, being developed through the Border Environment Cooperation Commission (now the North American Development Bank).

He also led interdisciplinary teams for environmental projects related to storm water pollution, heavy metals monitoring in soils and wastewater, solid waste management, and regulatory compliance. In addition, he has extensive knowledge of the federal permitting process for construction of international border-crossing facilities on the U.S.-Mexico border.

During his career in the private sector, he has worked on projects for the USIBWC, Cal-EPA, U.S. EPA, and other federal and state agencies, with a special focus on compliance with the National Environmental Policy Act (NEPA).

“We’re very excited to have Nicolas on board,” said Jayne Harkins, Commissioner, USIBWC. “His impressive background brings a strong blend of technical experience in wastewater systems and engineering to enhance the operations of the San Diego Field Office.”

Chapa received a Bachelor of Science in Agricultural Engineering from the Universidad Autonoma de Nuevo Leon (UANL), Monterrey, Mexico. He is currently pursuing his Ph.D. in Environmental Science and Engineering at the University of Texas at El Paso.
