This notice proposes to amend the pipeline construction requirements of Parts i92 and 195 by replacing the present regulations on the repair or removal of defective girth welds with performance standards for weld repair, and incorporating by reference the procedural requirements of Section 7.0 of API Standard 1104 in recognition of an American Petroleum Institute (API) June 1981 petition. The proposed requirements would permit the repair of weld cracks as well as multiple repairs of other weld defects under controlled conditions in a more cost effective manner and assure that the soundness and mechanical properties of a repaired weld will be equal to an acceptable new weld.
