Memo: Internal — Pipeline Safety Interpretation

Page 1July 26-27, 1983 NAMES OF PERSONS: Mike Kidd and Frank Fulton SUBJECT: Interpretation: 192.327 depth of cover in waterways DIGEST: Kdid [sic] asked if "navigable" in 192.327(e) applied to river, stream and harbor, or only river. If it applied only to rivers, then all pipelines in streams and harbors would have to be buried 48" deep. Fulton recalled that the concern during rulemaking was with large vessels only - anchors, etc. - and felt that the term "navigable" applied to all three. Therefore, it would not be necessary to have 48" of cover in all streams, rivers, and harbors. Only those streams, rivers, and harbors which support large vessel (ships, barges, etc.) traffic would require 48" of cover for a buried pipeline crossing. Less cover depth would be required for smaller or shallower streams, rivers, and harbors that do not support large vessel traffic. CONCLUSION: Notified Kidd of this "determination" Ivan A.
