A Unified Command has concluded cleanup and recovery efforts in the Richmond area after no sheen had been observed by crews since last Friday. The joint command had led the response to a Feb. 9 pipeline discharge at Chevron’s Richmond Refinery. An investigation is ongoing but preliminary results found an estimated 500-750 gallons of diesel/water mix was discharged from a quarter-inch hole in a pipe used to return a variety of excess oils and products to the refinery for reprocessing. No long term environmental impacts are expected from the incident, but as a precaution OSPR scientists took samples of water, sediment and mussels in the area. Lab results are still pending.

Cleanup and recovery efforts neared completion today in the Richmond area as shoreline assessment teams and aerial drones monitored land and water for residue from Tuesday’s pipeline leak at the Chevron Long Wharf. No sheen was detected in the bay and the only cleanup underway is along the waterfront next to the wharf. Keller Beach and public access points on Western Drive have reopened. The pipe involved remains isolated and out of operation and an investigation into cause is ongoing. Monitoring will continue over the holiday weekend and protective boom is in place near sensitive sites as a precaution. No oiled #wildlife have been observed.

OSPR’s team of incident investigators collected samples from recovered sorbent boom at the Richmond Long Wharf yesterday. The U.S. Coast Guard and Chevron are also conducting ongoing investigations. The investigations are kept independent of the response. 
The Unified Command responding to the pipeline release in Walnut Creek conducted a site walkthrough and sign off on the initial phase of the response Wednesday. The incident will now enter long term remediation phase facilitated by the SF Bay Regional Water Quality Control Board. Although petroleum hydrocarbons remain in soil underneath the San Ramon Bypass Channel, crews continue efforts to reduce the amount of product reaching the surface while remediation continues. 
Shoreline cleanup and assessment continues in the area impacted by Tuesday’s petroleum spill at the Chevron Richmond refinery. Cleanup is focused on Saltwater Station, a private beach near the initial release site. No oiled #wildlife observed and much of the sheen dissipated with yesterday’s sunny, warm conditions. Lighter products such as diesel tend to break down naturally with such weather conditions, and are easier to cleanup compared to thicker oil. It was estimated yesterday that 500-750 gallons of diesel/water mix was released in the incident. For the latest updates, visit https://recoveredoillineleak.com
