This amendment establishes a new Subpart I to Part 192 in Title 49, Code of Federal Regulations, containing the minimum Federal safety standards for the transportation of gas and for pipeline facilities used in this transportation. On April 30, 1970, the Department Issued a notice of proposed rule making, Notice 70-8, containing requirements for corrosion control (35 F.R. 2127, May G, 1970). Interested persons were invited to participate in the making of the proposed rules by submitting written comments before June 29, 1970. On June 6, 1970, an amended notice of proposed rule making was published in the FEDERAL REGISTER (Notice 70-10, 35 F.R. 8833) to make certain changes in the proposed rules relating to cast iron and ductile iron pipe. After a request for a public hearing on the requirements of these two notices, a public hearing (see Notice 70-12, 35 F.R. 10596, June 30, 1970) was held on July 20, 1970, and comment was received on the proposed applicability of the requirements to existing pipelines and to cast Iron or ductile iron pipe. The information and views presented in the comments and at the hearing have been fully considered, and are reflected in this final rule. Some sections contained in the notice have been consolidated, eliminated, or reorganized and most sections have been renumbered. The deviation table below indicates the corresponding section number in the notice for each section of the final rule.
