Dear Mr. Bishop:
Thank you for your timely submittal of the subject report dated July 22, 2013, from New South
Lumber's Graham Plant. The report included an assessment of the continuous opacity
monitoring system (COMS)that operated on Boiler 94 (ID No. B-4)during the first half of 2013.
The Division of Air Quality (DAQ)has completed its review of the COMS-related information
in the report and offers the following comments:
1. The report was reviewed for compliance with 20% opacity limit found at 40 CFR Part 60,
Subpart Dc and permit condition 2.1.B.2. There were no reported exceedances of the
applicable standard. Excess emissions from the wood-fired boiler were attributed to either
startup, shutdown, malfunction, or other exempt emissions. These emissions were reviewed
and allowed in accordance with applicable monitoring rules.
2. A review was also conducted for compliance with good operation and maintenance (O&M)
practices pursuant to 40 CFR 60.11(d), 40 CFR 60.13, permit specific condition 2.1.B.2, and
general condition F. When compared to the total operating time of the boiler during the first
quarter,percent excess emissions (%EE)were reported as 0.30%and percent monitor j
downtime (%MD) as 0.14%. For the second quarter, %EE was reported as 0.07% and%MD
as 0.18%. Thus, the COMS unit appears to indicate the use of good O&M practices since
quarterly %EE and%MD were less than 6% for any single calendar quarter or less than 3%
for two consecutive quarters.
