Attached are tables of results for the performance testing conducted at Thomaston Compressor Station, 

the purpose of this testing was to demonstrate compliance with the applicable standards outlined in 

Section 4.2.2 of the above referenced permit. CO tests were performed on-site November 26, 2006, using 

a portable analyzer for Emission Unit· C003 (Compressor Engine No.3) and Emission Unit C004 

(Compressor Engine No.4). All tests were performed in accordance with SNG's test protocol previously 

submitted to GEPD and, as shown on the following table. all average results are within permitted limits. 

I certify that based on information and belief formed after reasonable inquiry, the statements and
