Sheldahl Flexible Technologies Inc - West Facility - Air Permit

We invite you to comment on the draft air quality permit for Sheldahl Flexible Technologies Inc - West Facility.


Sheldahl Flexible Technologies in Northfield manufactures specialty electronic products such as flexible printed circuitry, flexible composite laminates, and specialty engineering products. The facility produces emissions from its mixing, laminating, screen printing, plating, etching, and stripping processes.

 

The draft permit reissues the facility’s air quality permit and does not authorize any construction or new emissions. The draft air permit limits emissions of volatile organic compounds and requires testing, monitoring, and recordkeeping for volatile organic compounds.


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.
