Update 4: Coast Guard, partner agencies to conduct fuel removal operations on sunken barge near Bay Bridge

SAN FRANCISCO — A unified command comprised of the U.S. Coast Guard, California Department of Fish and Wildlife’s Office of Spill Prevention and Response, San Francisco Department of Emergency Management, Vortex Marine Construction and Bay Area Rapid Transit District scheduled a fuel removal from the sunken 112-foot freight barge Vengeance Wednesday.

During fuel removal operations, the fuel remaining aboard the Vengeance barge will be pumped from the Vengeance into fuel containers positioned on a second work barge for disposal.

Global Diving and Salvage is expected to conduct fuel removal operations Wednesday, though the actual timing of the operation may fluctuate depending upon environmental and other conditions.

Though a discharge of fuel is not expected to occur during this transfer process, divers will secure an underwater fuel containment dome over the Vengeance fuel fill connection as a precaution to prevent any fuel from reaching the surrounding waters during the transfer. Pollution containment boom will also be available for deployment in the case of a larger pollution discharge.

Fuel will be removed from the Vengeance in order to prepare the barge for removal from the sea floor at a later date. Plan development for removal of the barge from the sea floor remains in progress and could take several additional weeks once fuel removal is complete.

Mariners are requested to abide by the 350-meter (1,148 feet) safety zone and monitor local media channels, as the safety zone is subject to change. Marine information broadcasts to local mariners will continue while the safety zone is in effect.

The Vengeance capsized April 7 south of the Bay Bridge.

Update: GROVE INCIDENT PROGRESS REPORT

BACKGROUND

The Office of Spill Prevention and Response and Crimson Pipeline formed a Unified Command to oversee cleanup operations following a pipeline spill in Ventura on June 23. The oil was quickly contained in the Hall Creek channel before it could reach the ocean.

CLEANUP PROGRESS

At the beginning of the response, the length of the spill was sectioned into Divisions A, B, C and D to manage varying conditions in different areas. (Spill Division Map) Patriot Environmental Services and National Response Corporation Environmental Services removed oil from the spill area with vacuum trucks, hand shoveling, and other mechanical methods. Cleanup work is continuing within current projected timeline for oil cleanup to be completed around September 23, followed by remediation and restoration of the area.

Division A –Recommendations have been submitted for some additional excavation in this area, and work assignments are being developed.

Division B –Additional excavation is occurring with guidance from geotechnical experts.

Division C –Crews will excavate and clean boulders and cobble in a 30 ft. stretch of the upstream portion of the exclusion zone, an area identified as a more dangerous zone owing to an adjacent steep, canyon wall with falling rocks and debris. Work will include the necessary measures to ensure a safe operation.

Division D – No observable impacts from oil were documented. Integrity of containment berms will be monitored and maintained.

REMAINING OIL ESTIMATES

All oil estimates are as of July 30.  Contaminated soil continues to be removed and oil estimates will be revised over time. Estimates of oil remaining at the spill site are made by measuring liquid oil reclaimed, estimating the amount evaporated (based on NOAA’s ADIOS model), and analyzing oil coated  vegetation and soil to derive a close approximation of oil content in excavated materials. Of the reported 44,772 gallons spilled, it is estimated that approximately 6,619 gallons have not been recovered as of July 30.

The Oil Recovery Assessment Pie Chart illustrates estimates of spilled oil that were recovered, evaporated, or remain onsite.

TIMELINE TO RESPONSE CLOSURE

The cleanup phase of the Grove Incident response is nearing its conclusion. By early September, Unified Command expects to begin the sign-off process certifying that cleanup is finished in individual parcels. By the second half of September, the remediation plan is expected to be in place, and restoration will begin. All restoration work is expected to be concluded by the second half of October, at which point the response will begin its monitoring stage.

BACKGROUND

A multi-agency response effort has been established in Ventura, where a pipeline spilled crude oil into a dry gorge near Grove Lane on June 23. The oil was contained before it could reach the ocean. A Unified Command is overseeing the ongoing cleanup operations.

CLEANUP

 At the beginning of the response, the length of the spill was sectioned into four divisions to manage varying conditions in different areas. Division A is located at the top where the spill originated. Divisions B, C and D progress in order down the canyon. (Spill Division Map) Patriot Environmental Services and National Response Corporation Environmental Services removed oil from the spill area with vacuum trucks, hand shoveling, and other mechanical methods. Cleanup has progressed to hand cleaning of rocks. Geotechnical experts have conducted an inspection and are assessing methods for conducting remaining work safely. Following is current status for each division:

HEALTH AND AIR QUALITY:

The results of ongoing air monitoring and sampling indicate that the air is safe to breathe in the community surrounding Prince Barranca. These results are being shared daily to the Grove Incident Unified Command (UC), which includes representatives from the U.S. Environmental Protection Agency (US EPA), the California Department of Fish and Wildlife’s Office of Spill Prevention and Response (CDFW/OSPR), and Crimson Pipeline.

Air monitoring and sampling results have also been reviewed by the Ventura County Department of Public Health. The Ventura County Department of Public Health was satisfied that the air monitoring operations are both thorough and complete and expressed that the reported results do not suggest a risk to public health.
