Draft Federal Part 70 Permits for the Sable Offshore – Santa Ynez Unit Stationary Source

The Santa Barbara County Air Pollution Control District (District) has issued five (5) draft federal Part 70 permit to the Sable Offshore Santa Ynez Unit Stationary Source.

The Santa Ynez Unit produces crude oil and natural gas from Platforms Hondo, Harmony and Heritage, which are located off the California coast in the Santa Barbara Channel. The oil and gas are transported through a subsea pipeline and treated the Las Flores Canyon Oil and Gas Plant and the Pacific Offshore Pipeline Company (POPCO) Gas Plant, both located in Las Flores Canyon which is approximately 20 miles west of Santa Barbara, California.

This permitting action is a renewal of the federal Part 70 permits for the facility. The Part 70 permit regulates the production and processing of oil and natural gas. Once issued by the District and the US Environmental Protection Agency (USEPA), the Part 70 permit will be valid for three years. The permit will be enforceable by the District, USEPA and the public.
