The County Public Health Department, Environmental Health Services Division has provided the following report regarding a release of sulfuric acid in San Miguel. 

The sulfuric acid was contained by the Hazardous Material Response Team and thus is very unlikely cause a threat to public health. 

Report:

  1. At approximately 1 PM on Thursday, March 26, Environmental Health Services was notified by County Public Works of an unknown chemical pooled on Cross Canyons Rd just south of the intersection with Indian Valley Rd in San Miguel.  An Environmental Health Specialist, in conjunction with the County Hazardous Material Response Team, determined the material to be sulfuric acid released from a storage tank on a vineyard at 8585 Cross Canyons Rd, San Miguel, CA.  The release was not ongoing when County personnel arrived, as the acid had leaked out of the tank to the level of the puncture.  The acid that leaked from the tank was partially absorbed into the soil, but excess liquid moved down a hillside to Cross Canyons Rd.
  2. Some of the acid pooled onto Cross Canyons Rd. and some also entered a storm drain that leads to the Salinas River.  The impacted roadway was coned off to direct traffic away from the spill.  A hazardous waste remediation company was dispatched and arrived onsite in the late afternoon.
  3. The release was contained and partially neutralized in the early afternoon by the Hazardous Material Response Team and thus very unlikely cause a threat to public health.  The hazardous waste remediation company was further absorbing and neutralizing the soil, road, and storm drain as of 6:30 PM on March 26.
  4. The puncture of the tank was a result of an impact by a trailer towed by a farm tractor.
  5. County Environmental Health remained on scene at the time of issuing this report to oversee cleanup by the hazardous waste remediation company.
