As plans move forward for a massive desalination plan in Rosarito Beach, a proposed pipeline to carry some of that water to San Diego County is undergoing scrutiny by the U.S. State Department. Through October 14, members of the public are invited to comment on whether the project proposed by the Otay Water District is the national interest. The department recently concluded its final environmental review of the pipeline. Because the structure would cross an international border, the department must evaluate the project before a Presidential Permit can be issued.
