Dear Mr. Bishop:
Thank you for your timely submittal of the subject report dated July 26, 2012. The report included
an assessment of the continuous opacity monitoring system (COMS)operating at the New South
Lumber Graham Plant during the first half of 2012. The Division of Air Quality (DAQ)has
completed its review of the COMS-related information and offers the following comments:
i. The report was reviewed for compliance with 20% opacity limit found at 40 CFR Part 60,
Subpart Dc and permit condition 2.1.13.2. There were no reported exceedances of the
applicable standard. For Boiler#4 (ID No. B-4), excess emissions 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 conducted for compliance with good operation and maintenance (O&M)
practices pursuant to 40 CFR 60.11(d),NCAC 2D .0606, and permit condition 2.1.B.2. When
compared to the total operating time of the boiler during the first quarter,percent excess
emissions (%EE)were reported as 0.21%and percent monitor downtime (%MD) was reported
as 0.00%. For the second quarter, %EE was 0.06% and %MD was 0.00%. 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.
