RECOMMENDATION: The emissions from the above units appear to be in compliance with the
PM10 limits in the Approval Order. However, the Chopping Line
Baghouse also contains limits for PM2.5 which were not tested for
during this stack test, and the test results for PM10 exceed the limits set
for PM2.5. The source was contacted and reminded that the Approval
Order requires the Wire Chopper Baghouse meet the limits in Condition
II.B.3.a for PM2.5 and that they will need to a schedule test to determine
compliance.
