Draft Federal Part 70 Permits for the ExxonMobil 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 ExxonMobil Santa Ynez Unit Stationary Source.

Please Note:  The draft Part 70 renewal permits for the ExxonMobil Santa Ynez Unit (SYU) stationary source that are available for public review are unrelated to the proposed ExxonMobil Interim Trucking for SYU Phased Restart Project and do not authorize trucking operations from the ExxonMobil SYU source.  The proposed ExxonMobil Interim Trucking for SYU Phased Restart Project is currently under review and consideration by Santa Barbara County Department of Planning & Development.  More information is available here:

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.

Copies of the permit application and the draft permits are available for review from April 27, 2021 to May 27, 2021 on the District website. For more information or a copy of the permit, please contact William Sarraf at (805) 961-8888 or at [email protected]

Only the federally enforceable conditions in Sections 9.A, 9.B, and 9.C of the permit are subject to public review. Comments on these sections should be submitted, in writing, to the District at the address below (attn.: William Sarraf) by May 27, 2021.
