Document Description
This Draft Subsequent Environmental Impact Report (SEIR) has been prepared to address the environmental impacts associated with the Renewable Fuels Conversion Project (Project). AltAir has been in partnership with Paramount Petroleum since 2013, when the Paramount Refinery (refinery) began the process of converting portions of their oil refinery into renewable fuels production, under the Original Paramount Petroleum AltAir Renewable Fuels Project (Original Renewable Fuels Project). This SEIR is a subsequent document to the Mitigated Negative Declaration (MND) that was prepared for the Original Renewable Fuels Project adopted December 2013 and revised per an Addendum May 2014. In 2018, World Energy purchased AltAir and the refinery, and AltAir became a wholly owned subsidiary of World Energy. Under World Energy, AltAir proposes to complete the conversion of the refinery to manufacturing only renewable fuels at a higher throughput level than the Original Renewable Fuels Project.
