POET Biorefining (Preston) - Air Permit

We invite you to comment on the draft air quality permit for POET Biorefining's facility in Preston.

POET Biorefining produces ethanol at its facility in Preston. The facility receives and mills grain, then ferments and distills the grain to produce the ethanol.

The draft air permit allows the facility to install new milling equipment, new fermentation tanks, and new control equipment to produce more ethanol on an annual basis. The permit extends existing particulate matter and volatile organic compound emission limits to the increased production rates and includes testing to make sure limits continue to be met. The permit also establishes limits on the number of trucks that can deliver grain each day. 

An air quality operating permit is required for certain existing facilities or the construction of new facilities that have the potential to emit a significant level of any regulated pollutant. The permit includes all requirements for operation and procedures, applicable rules, emission standards, monitoring, recordkeeping, and reporting. If additional conditions change and modifications are necessary, the MPCA may review and amend the permit.
