Dear Sir:
This is in reply to your letter of May 8, 1978, asking if gas pipelines to be operated above 20 percent SMYS that lie within
a highway or railway right-of-way must meet the requirements of 49 CFR 192.243(d)(4) whether they cross or parallel
the highway or railway.
Section 192.243(d)(4) sets forth the percentage of each day’s field butt welds that must be nondestructively tested on
pipelines to be operated at 20 percent of SMYS or more when such testing is required by Section 192.241(b). Paragraph
(d)(4) states that: “Within railroad or public highway rights-of-way…100 percent.” Under this requirement, the term
“within” refers to pipelines inside the right-of-way, including those that either cross or parallel a railroad or highway.
Thus the applicability of Section 192.243(d)(4) is not affected by the relative position of the highway or railroad to a
pipeline within the right-of-way.
We trust that this adequately responds to your inquiry. If we can be of any further assistance, please let us know.
Sincerely,
Cesar DeLeon
Associate Director for
Pipeline Safety Regulation
Material Transportation Bureau
