To meet demand for renewable fuels driven by California’s Low Carbon Fuel Standard (LCFS), a confidential client planned to construct and operate a 3,500 barrel per day (BPD) renewable diesel production plant in Utah. The facility would process biological oil feedstock consisting of yellow grease (recycled cooking oil), plant oils, and animal tallows into renewable diesel fuel, renewable hydrotreated naphtha, and glycerin.
Working under a tight construction schedule, the client hired Barr to assist in applying for an air-quality permit for construction called an approval order (AO). We coordinated with the plant developer on a permitting strategy to quickly prepare and submit the application. In six weeks, Barr completed the permit application, which, under Utah requirements, required a Best Available Control Technology (BACT) cost evaluation and Hazardous Air Pollutants (HAPs) Emissions Impact Analysis.
Barr also supported the client in reviewing and negotiating the conditions of the draft permit with the Utah Division of Air Quality (DAQ). The permit was issued within six months of the application, allowing the project to continue with construction.
