Esparto, California — Following a devastating explosion that killed seven men at a fireworks facility nearly two months ago, newly released public records reveal Yolo County officials had prior knowledge of illegal firework storage on the site. The property, zoned solely for agricultural use, was not permitted to store any pyrotechnics, raising questions about oversight and accountability.
Initially, county officials stated that the facility, owned by a Yolo County sheriff’s lieutenant and his wife, lacked the necessary local permits to operate as a fireworks storage site. Despite this, documents indicate a number of county officials were aware that fireworks had been stored there since at least 2022. This concern was highlighted in an email from Scott Doolittle, Yolo County’s chief building official, who acknowledged receiving tips about the facility’s use for running a pyrotechnics business, mentioning a complex relationship involving law enforcement personnel.
In Doolittle’s communications, he expressed caution regarding any enforcement actions, particularly due to connections with the sheriff’s office. It raised flags, particularly when a permit request for a “metal storage building” also suggested excessive electricity use — exceeding limits allowed for agricultural structures. The email noted this as a warning sign of inappropriate use of the building.
The property in question hosted two fireworks companies, including one operated by a volunteer firefighter. Since the explosion, the sheriff’s lieutenant and his wife have been placed on administrative leave as investigations continue.
Further correspondence revealed that fire officials confirmed the businesses were federally licensed, yet there were no documented local safety inspections during or after the facility’s operation. One email mentioned that if the facility dealt with new or waste fireworks, it would be required to submit a Hazardous Material Business Plan, which did not appear to have been enforced.
In a statement, the Yolo County Board of Supervisors indicated that their staff had conducted a site visit mid-2022 and found no illicit fireworks. However, they acknowledged that there had been no formal inspections following that visit despite evidence that fireworks activities had escalated during the following months.
Reports indicate that local officials were informed the structures at the site lacked proper fire protection measures and were not intended for regular occupancy. Investigators from Cal Fire and other authorities have served multiple search warrants as they probe the circumstances surrounding the explosion and whether any charges will result from their findings.
State Fire Marshal Daniel Berlant emphasized the investigation has identified significant gaps in regulations at various governmental levels. Prosecutors from the Yolo County District Attorney’s Office confirmed they are preparing potential charges linked to the incident.
As the county launches a review of its code enforcement practices, the incident has illuminated the critical need for better oversight and adherence to safety protocols in the handling of hazardous materials. The ongoing investigation continues to bring to light the responsibilities of local authorities in preventing such tragedies.
