SUPPLEMENTARY INFORMATION:

PHMSA received a special permit request from CGT, a subsidiary of TC Energy, seeking a waiver from the requirements of 49 CFR 192.505(c): Strength test requirements for steel pipeline to operate at a hoop stress of 30 percent or more of SMYS, 49 CFR 192.611: Change in class location: Confirmation or revision of maximum allowable operating pressure, and 49 CFR 192.619: Maximum allowable operating pressure: Steel or plastic pipelines. The special permit request is for special permit segments that have either a Class 1 to 3 location change, a pressure test duration below eight (8) hours, or a pressure test times maximum allowable operating pressure (MAOP) safety factor that is below 1.25.

This special permit is being requested in lieu of pipe replacement, pressure reduction, or a new pressure test for 61 special permit segments totaling 114,124 feet (approximately 21.614 miles) in total length of pipeline. The pipeline special permit segments consist of the following:

  • Lafayette Parish, Louisiana—8,307 feet of 24-inch diameter East Lateral (EL) 200 Pipeline and 4,187 feet of 30-inch diameter EL 400 Pipeline;
  • Franklin Parish, Louisiana—1,312 feet of 30-inch diameter Mainline (ML) 100 Pipeline and 8,485 feet of 30-inch ML 200 Pipeline;
  • Union County, Mississippi—4,173 feet of 30-inch diameter ML 100 Pipeline, 3,976 feet of 30-inch ML 200 Pipeline, and 3,897 feet of 36-inch diameter ML 300 Pipeline;
  • Alcorn County, Mississippi—5,062 feet of 30-inch diameter ML 100 Pipeline, 5,331 feet of 30-inch ML 200 Pipeline, and 1,940 feet of 36-inch diameter ML 300 Pipeline;
  • Macon County, Tennessee—3,896 feet of 30-inch diameter ML 100 Pipeline, 3,885 feet of 30-inch ML 200 Pipeline, and 3,949 feet of 36-inch diameter ML 300 Pipeline;
  • Menifee County, Kentucky—62 feet of 30-inch diameter ML 100 Pipeline and 199 feet of 30-inch ML 200 Pipeline;
  • Montgomery County, Kentucky—1,008 feet of 30-inch diameter ML 100 Pipeline and 803 feet of 30-inch ML 200 Pipeline;

  • Madison County, Kentucky—22,385 feet of 30-inch diameter ML 200 Pipeline and 823 feet of 30-inch ML 300 Pipeline; and
  • Rowan County, Kentucky—185 feet of 30-inch diameter ML 200 Pipeline.

The proposed special permit will allow operation of the original Class 1 pipe in Class 3 locations. The CGT pipelines were constructed in the following time periods and operate at the MAOPs listed below:

  • 24-inch diameter EL 200 Pipeline was constructed in 1954 and has a MAOP of 973 pound per square inch gauge (psig);
  • 30-inch diameter ML 400 Pipeline was constructed in 1971 and has a MAOP of 1,007 psig;
  • 30-inch diameter ML 100 Pipeline was constructed between 1953 to 1954 and has a MAOP of 935 psig;
  • 30-inch diameter ML 200 Pipeline was constructed between 1958 to 1965 and has a MAOP of 1,007 psig; and
  • 36-inch diameter ML 300 Pipeline was constructed between 1968 to 1971 and has a MAOP of 1,007 psig.

The special permit request, proposed special permit with conditions, and Draft Environmental Assessment (DEA) for the CGT pipelines are available for review and public comments in Docket No. PHMSA-2019-0201. 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 comments 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.
