Millions of dollars from county reserves will go toward new initiatives intended to provide South County residents with some relief from the ongoing Tijuana River sewage crisis. On Wednesday, the San Diego County Board of Supervisors approved setting aside nearly $9 million from its rainy-day funds to pay for a pipeline project in the Tijuana River Valley. About half the funds, or $4 million, will go toward expanding the San Diego Air Pollution Control District’s Air Improvement Relief Effort program. Varying levels of hydrogen sulfide have been detected in South County communities near the polluted Tijuana River. County funds will also cover the following:$2.5 million for a pipeline project at Saturn Boulevard in the Tijuana River Valley, an area researchers have found to be a hot spot for airborne sewage pollution.
