PHMSA received a special permit request for the renewal and addition of pipeline segments from CGT seeking a waiver from the requirements of 49 CFR 192.611(a): Change in class location: Confirmation or revision of maximum allowable operating pressure. This special permit is being requested in lieu of pipe replacement or pressure reduction for 41 special permit segments consisting of 9.15 miles in 11 existing special permit segments and an additional 18.51 miles in 30 new special permit segments on the CGT pipeline system. The 27.66 miles of proposed special permit segments are located in Williamson, Davidson, Trousdale, and Wilson Counties, Tennessee. The CGT pipeline class locations in the special permit segments have changed from a Class 1 to a Class 3 location. The CGT pipeline special permit segments are 30-inch and 36-inch diameter pipelines with an existing maximum allowable operating pressure of either 935 pounds per square inch gauge (psig) or 1,007 psig. The installation of the special permit segments occurred between 1953 and 1970.
The special permit request, proposed special permit with conditions, and Draft Environmental Assessment (DEA) for the CGT pipeline are available for review and public comment in Docket No. PHMSA–2008–0066. We invite interested persons to review and submit comments on the special permit request and DEA in the docket. Please include any comments on potential safety and environmental impacts that may result if the special permit is granted. Comments may include relevant data.
Before issuing a decision on the special permit request, PHMSA will evaluate all comments received on or before the comment closing date. Comments received after the closing date will be evaluated, if it is possible to do so without incurring additional expense or delay. PHMSA will consider each relevant comment it receives in making its decision to grant or deny this special permit request.
