SUBJECT: Review of 2015 First Semester COMS Report
New South Lumber Company, Inc. —Graham Plant

Facility ID No. 0100237
Air Permit No. 06740T18
Dear Mr. Bishop:
Thank you for your timely submittal of the subject report dated July 21, 2015, from New South
Lumber's Graham Plant. The report included an assessment of the continuous opacity
monitoring system (COMS)that operated on Boiler#4 (ID No. B-4) during the first half of 2015.
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 violations 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.l.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 0.04% and percent monitor
downtime (%MD) as 0.10%. For the second quarter, %EE was reported as 0.06% and %MD
as 0.05%. Thus, the COMS unit appears to indicate the use of proper O&M practices for
minimizing emissions since quarterly %EE and %MD were less than 6% for any single
calendar quarter and less than 3% for two consecutive quarters.
