CD -40 CFR Part 60, Subparts A and UUU.
Facility ID No.1900104
Dear Mr. Bond:
The Division of Air Quality (DAQ)has reviewed your first semester 2008 (January 1,through Tune
30, 2008) opacity emission reports from the C&S Dryer, CL 1 and CL 21'reheaters. 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 # 09006R00. The reports were also reviewed for
compliance with good operation and maintenance practices set forth in 40 CFR Part 60, Subparts A and
UUU and implemented in the EPA Region IV CEM Enforcement Plan (CEP) and in accordance with
EPA's High Priority Violations (HPVs) guidance.
Based on the review, the opacity excess emissions and monitor downtime for the period were
reported and confirmed as follows:
UNIT 1st SEMESTER 2008
C&S Dryer Excess Emissions 0.0%
Monitor Downtime 0.72%
CLIPreheater Excess Emissions 0.0%
Monitor Downtime 0.89%
CL2 Pre heater Excess Emissions 0.0%
Monitor Downtime 1.21%
When the reports are reviewed with respect to the emission control standard(opacity limit)no six-
minutes opacity exceedances were noted from the C&S Dryer, CL1Preheater, and CL2 Pre heater. Also,
when the reports are reviewed for compliance with good operation and maintenance practices, excess
emissions and monitor downtime were reported and confirmed (as shown above)to be below the CEP
criteria and the HPVs guidance. Therefore no further action is required.
