Dear Mr. Smith:
Thank you for your letter of June 8, 1979, requesting an interpretation of the term "uprating." You inquire if increasing the pressure in a distribution line to 17 psi which had been in operation for 48 years at a pressure of 5 1/2 ounces can be classified as an "uprating."
The regulations prescribing requirements for uprating (Sections 192.555 and 192.557) are applicable to pipelines which are intended to operate at a pressure higher than the current
maximum allowable operating pressure established under 49 CFR 192.619. Therefore, if the established maximum allowable operating pressure for the line in question is less than 17 psi, then the line is subject to the uprating regulations of Subpart K.
I trust that this responds adequately to your inquiry.
Sincerely,
Cesar DeLeon
Associate Director for
Pipeline Safety Regulation
Materials Transportation Bureau
