(b)

1. (1)

   1. (A) The hydrostatic spike test shall be at least 139 percent of the maximum operating pressure of the pipeline and shall not exceed 80 percent of the specific minimum yield strength, as determined appropriate by the State Fire Marshal.

   2. (B) Notwithstanding subparagraph (A), at the operator’s request, the minimum hydrostatic spike test pressure may be lower than 100 percent of the specified minimum yield strength if the maximum operating pressure of the pipeline is correspondingly reduced.

      1. (i) Pursuant to this subparagraph the hydrostatic spike test shall be at least 139 percent of the reduced maximum operating pressure of the pipeline, as determined appropriate by the State Fire Marshal.
      2. (ii) The hydrostatic spike test shall be performed in segments to ensure every elevation point is tested.
2. (2) If the specified minimum yield strength is unknown, the specified minimum yield strength shall be determined pursuant to Section 195.106(b) of Title 49 of the Code of Federal Regulations before performing the hydrostatic spike test.
