CEMEX Air District Permit Application Number 28001

CEMEX has submitted an application to the Bay Area Air Quality Management District to increase the permitted throughput capacity at its barge conveyor system, S-14, located in San Francisco, California. The request seeks to significantly raise the annual sand throughput from 60,000 tons per year to 235,572 tons per year, with operational limits of no more than 818 tons per day and 69 tons per hour to manage emissions and operational impacts. In addition to the sand increase, the application formally permits the handling of aggregate via the same conveyor for the first time, with an annual allowance of up to 153,803 tons, subject to daily and hourly caps of 535 tons and 45 tons, respectively. These changes are intended to enhance operational efficiency while maintaining compliance with air quality standards through strict throughput controls. The application is under review by the regulatory agency, with point of contact information provided for public and regulatory inquiries, and the project is associated with the local environmental review process under CEQA.
