Summary

Richmond emergency officials told the City Council that a refinery explosion in Martinez, sustained flaring at Chevron and excessive rainfall produced localized flooding and sewer overflows over a recent weekend, and that there was no known threat to Richmond residents.

Richmond public-safety officials briefed the City Council on storm impacts and two regional industrial incidents over the weekend, and they urged residents to enroll in official emergency-notification systems.

Fire Chief Aaron Osorio said the county and Richmond Office of Emergency Services monitored an early Saturday explosion and fire at Martinez Refining Company that produced a smoke plume affecting Martinez, Pacheco, Bay Point and parts of Solano County. Mutual-aid firefighting brigades, including Chevron Fire Department crews, assisted at the scene; Osorio said the fire burned for about a day and a half and that the county's Office of Emergency Services issued informational Nixle/Nixel alerts to reassure the public that there was no known community risk.

Chief Osorio also described a related but distinct incident of intermittent flaring at Chevron that began Saturday morning and continued through Sunday. Osorio said Chevron reported the activity as an unexpected flaring event during a planned unit start-up; the flaring lasted long enough to trigger a county Level 1 community-warning-system alert. Richmond Fire and OES monitored the incident and issued informational notices because the sustained intermittent flaring prompted community inquiries; Osorio said there was no threat to Richmond residents.

Storm impacts and local response City staff and public-works crews reported excessive rainfall with localized flooding at certain intersections and several sanitary sewer overflow incidents. Public works and Water Resource Recovery staff have been tracking and responding to reported overflows. Chief Osorio reminded residents that sandbag stations are available "behind Station 64 on Hartnett at Bayview" and at the public works facility; residents in need of assistance, including seniors and disabled residents, may call (510) 620-6509 for help.

Emergency notifications and community guidance Osorio emphasized three notification systems: the countywide Community Warning System (CWSAlerts.com) for Level 2 and 3 incidents that require action, a January-launched county Level 1 flaring notification (text CC HEALTH to 21423) for informational flaring notices, and the city's Nixle/Everbridge messages (text your ZIP code to 77711 or sign up on the county/city sites). He urged residents to register for all three systems for redundancy.

PG&E-related tree fire in May Valley Council members asked about a separate May Valley incident in which a tree branch contacted PG&E lines, energized and burned. Chief Osorio said fire crews reached the scene in about 4.5 minutes but could not extinguish the energized branch until PG&E de-energized the lines; PG&E took about 40 minutes to respond. No injuries and no residential property damage were reported, and the incident highlighted the need for right-of-way vegetation management.

Why it matters and next steps City officials said they will continue to monitor regional refinery activity and to coordinate with county OES and mutual-aid partners. The city's immediate recommendations were practical: sign up for CWS and Nixle alerts, use sandbag stations if needed and report storm-related sewer overflows to public works.

Ending Council members thanked first responders for round-the-clock monitoring and asked staff to follow up on Chevron and PG&E response timelines; staff said they would provide additional updates to council members by email.
