Impulse Space outlines technical reasons for vertical cryogenic tanks and lists safety controls

Impulse Space representatives answered commissioner questions about alternatives and safety measures and said vertical tanks support gravity-fed distribution through the facility and reduce refill frequency. Mike McDermott, the company’s director of infrastructure, said burying tanks or changing to horizontal tanks would create inspection, pump and noise issues, and noted underground petroleum lines limit excavation. He told commissioners the variance request was driven by safety, technical and regulatory constraints rather than preference.

The company described multiple safety measures that would be required and inspected at later permitting stages: remote telemetry monitoring that sends automatic notifications to senior test engineers, oxygen monitors around tanks, plan-check and field inspections by the fire department and CUPA/LA County Fire review, and Cal/OSHA oversight of employee safety. The applicant emphasized ongoing neighborhood outreach (flyers, FAQ site, door-to-door contact) and said it will continue to engage neighbors.
