WC-1 Woodworking operations BF-1 Bagfilter(3,060 square feet of filter area).
Observed: The bagfilter is installed on two woodwaste collection systems in the plant. Collected
woodwaste from the bagfilter is transferred to a woodwaste storage bin(ID No. I-WSB-1)via a closed-
loop transfer cyclone(ID No. I-CD-2; 84-inch diameter). The cyclone does not vent back into the
bagfilter or the atmosphere. The bagfilter exhaust can be vented to the outdoor atmosphere or returned
into the plant. During this inspection,the woodworking operation and bagfilter were in operation.

8. NESHAP/NSPS Review
The facility does not have a generator, fire pump or gasoline storage tank onsite.
The facility is subject to NESHAP Subpart 6J. This Rule applies to the No 2 fuel oil-fired boiler
(ID No. I-B1; 0.47 million Btu per hour maximum heat input). The boiler is considered an
existing unit since it was constructed prior to June 4,2010. The facility must implement a tune-
up program as a management practice. The boiler is less than 5 million Btu per hour and a
seasonal-use boiler. A boiler tune-up is required every five years. The boiler was not required to
perform an energy assessment, since it is rated at less than 10 million Btu per hour.
The facility must comply with the notification,recordkeeping and reporting requirements under
General Provisions—Subpart A. They must also maintain documentation on file that
demonstrates compliance with the tune-ups. Facility records indicate that a boiler tune-up was
performed on January 11,2017 by Link Boiler. The next tune-up will be due January 11,2022.
The tune-up due on January 11,2022 had not been completed at the time of this inspection.
9. Summary of changes needed to the current permit:
None.
10. Compliance assistance offered during the h�pection:
None.
11. Section 112(r)applicability:
This facility does not appear to be subject to the requirements of the Chemical Accident Release
Prevention Program, Section 112(r)of the Clean Air Act.

12. Compliance determination:
Based on my observations,this facility did not appear to be in compliance with the applicable air
quality regulations at the time of this inspection. An NOV/NRE will be issued for not completing
the boiler tune-up on time.
