Zenith Energy

Zenith Energy Terminal Holdings, LLC is a fossil fuel transloading facility—meaning the company accepts fuel products from one mode of transportation and passes them along to another. Zenith Energy is located in NW Portland at 5501 NW Front Avenue.

On Aug. 10, 2021, DEQ held a virtual public engagement meeting to present information to the community about the various ways DEQ regulates Zenith Energy, including air quality, water quality and spill response. Specifically, DEQ provided presentations on the status of the air quality permit renewal application, the proposed stormwater construction permit, the existing industrial stormwater permit and DEQ’s spill response program.

Air quality

DEQ issued Zenith Energy’s Title V air quality permit on May 16, 2007, for a term of five years, with an expiration date of April 1, 2012. Since Zenith submitted a timely and complete renewal application, DEQ administratively extended the permit. Zenith has continued operating in compliance with the 2007 air quality permit.

On Jan. 11, 2021, DEQ determined that it needed additional information from Zenith in order to continue processing the renewal application. DEQ requested Zenith provide an updated Land Use Compatibility Statement from the City of Portland by May 31, 2021. In response to a request from Zenith, DEQ extended that deadline until Aug. 31, 2021.

On Aug. 27, 2021, the City of Portland issued a decision denying Zenith’s application to the City for a LUCS for this facility. On Sept. 1, 2021, DEQ issued a proposal to deny Zenith’s permit application renewal. The denial takes effect in 60 days unless Zenith asks for an administrative hearing.

Stormwater construction

On Oct. 4, 2021, DEQ issued stormwater construction permit coverage to Zenith related to changes at the facility for the handling of renewable fuels. This permit coverage is under the general 1200-C Construction Stormwater General Permit. There are no special conditions for individual facilities, and they are not issued individual permits.

DEQ held a public hearing for this permit on Aug. 19, 2021, following the general public engagement meeting. After reviewing public comment, DEQ has determined Zenith Energy meets the criteria for stormwater construction permit coverage.
