August 30, 1971

Mr. John P. Irwin
Chief Engineer
State Corporation Commission
Topeka, Kansas 66612

Dear Mr. Irwin:

Thank you for your letter of August 5, 1971, in which you ask, "...will the Office of Pipeline
Safety continue to use the standards and specifications with 1970 and earlier dates for an
extended period of time or will these have to be continually updated as new revisions become

Our answer is that it will be necessary for OPS to continually review new editions of the
specifications and standards as they become available, and if they are found to be acceptable add
them, where appropriate, to the regulations. Notification will be published in the Federal

Materials manufactured under the previously listed specifications and standards will still be
acceptable for use to permit using materials that were already manufactured. At present there are
no plans for dropping from the list the editions of the various specifications and standards now

We recommend that as a minimum you purchase the latest editions presently listed in Appendix A
as amended, and earlier editions, if they are available. Materials manufactured to meet
specifications that are a later edition than those listed in Appendix A, but that are certified by the
manufacturer to at least meet the requirements of the latest presently listed specifications, will be
considered acceptable.

If we can be of any further help in this matter, please advise.


Joseph C. Caldwell
Acting Director
Office of Pipeline Safety
