No. CD -40 CFR Part 60, Subparts A and UUU.
Facility 1D No.1900104
Dear Mr. Funk:
The Division of Air Quality(DAQ) has reviewed your second semester 2009(July 1,through
December 31, 2009)opacity emission reports from the C&S Dryer, CL 1 and CL 2Preheaters. The reports
were reviewed for compliance with the monitoring and reporting requirements of the emission control
standard(opacity limit) set forth in the current Air Quality Permit# 09006T01. The report was also
reviewed for compliance with good operation and maintenance(O&M)practices set forth in 40 CFR Part
60, Subparts A and UUU and implemented in the North Carolina Continuous Monitoring Enforcement Plan
(NCCEP).
Based on the review,the opacity excess emissions and monitor downtime for the period were
reported and confirmed as follows:
UNIT FIRST SEMESTER 2009
C&S Dryer Excess Emissions 0.0%
Monitor Downtime 3.20%
CL1Preheater Excess Emissions 0.0%
Monitor Downtime 1.50%
CL2 Pre heater Excess Emissions 0.0%
Monitor Downtime 2.36%
When the reports were reviewed for compliance with the emission control standard(opacity limit),
no opacity excursion was reported. Therefore, no further action is required.
Also, when the reports are reviewed for compliance with good O &M practices, excess emissions
and monitor downtime were reported and confirmed(as shown above)to be below the NCCEP criteria.
Therefore no further action is required.
