# AIRPROTECTIONBRANCH

Dear Mr.Harris:
Attached are tables of results of the semi-annual RICE MACT testing at Hall Gate Compressor Station. CO tests were performed on-site December 16, 2005. using a portable analyzer for Emission Unit C003 (Compressor Engine No.3). All tests were performed in accordance with SNG's approved test protocol previously submitted to GEPD and, as shown on the following table, all average results are within permitted limits.
Based on Table 3 to Subpart ZZZZ of 40 CFR, Part 63

- Subsequent Performance Tests, Southern Natural Gas Company has demonstrated compliance for two consecutive tests and will be reducing the frequency ofsubsequent tests to annually.
I certify that based on information and belief formed after reasonable inquiry, the statements and information in this documentare true, accurate, and complete.
Ifyou have any Questions, please contact Mr. Tim McKellar at205-325-7684. Very truly yours,
