SUBJECT: Part 75 EPA Field Audit Summary Report
Primary Energy—Southport Facility,Units 1 and 2
Facility I.D. No. 1000067 OBIS 10378
Dear Mr. Haynes:
Attached is the Part 75 Level I audit report for Primary Energy's Southport Facility, Units 1 and 2 that I
conducted on February 26, 2007. The original RATA audit dates were changed with short notice to
accommodate installation of new flow monitors. The audit addressed all aspects of a Level I audit
including: Inspections of the CEMS and records review.
During the Level I audit, no compliance problems involving any regulatory requirements of Part 75 were
observed. The Quality Assurance manual appears complete and fully implemented. The maintenance logs
as well as emission data records appear complete.
Records from EPA's Monitoring Data Checking software 4.2.57 (MDC 4.2.57)were checked with facility
records. The facility information was consistent with the MDC information for missing data, failed
calibrations, linearity test reports, CEMs model numbers and serial numbers. These records correctly
reflect the daily and quarterly activities on the CEM systems. Additional data and RATA results are
attached in Appendix 1.
If you have any questions regarding this audit,please call me at(919) 715-0726.
