Integrity Air Monitoring,Inc.performed National Council of the Paper Industry for Air and Stream
Improvement(NCASI) Chilled Impinger Method for use at Wood Products Mills 98.01 on the biofilter
CD-18 to determine formaldehyde and methanol destruction and removal efficiency(DRE). Testing was
performed simultaneously at the inlet and outlet of CD-18. The emissions test results demonstrate
compliance with the applicable regulations.
The medium density fiberboard(MDF)process is comprised of refiner ES-01,energy system ES-02-A,
two stage dryer ES-02-B,natural gas-fired dryer burners ES-02-C-1 and ES-02-D,MDF board cooler
ES-06-B, and MDF press and press hall ES-16. These sources vent to the biofilter CD-18.
40 CFR 63 Subpart DDDD NESHAPS.Plywood and Composite Wood Products applies and Table 1B
provides six options for complying with the standard. Arauco Panels chose to comply using option 5 by
reducing formaldehyde emissions by 90%. A summary of the emissions test results is shown in the table

Formaldehyde 27.31b/hr 0.80 lb/hr 97.1% 90% 63 Subpart
Methanol 90.9lb/hr 64.51b/hr --- --- DDDD Yes
The refiner averaged 29.29 bone dry metric tons per hour(BDMT/hr) during testing. The average
throughput for the press during testing was 3 8.3 5 cubic meters per hour(mYhr)and the biofilter average
temperature was 140.9"F. The emissions test results demonstrate compliance with the requirements of 63
