This amendment establishes a new 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 for this transportation. The Natural Gas Pipeline Safety Act was enacted on August 12, 1968. It re- quired the Secretary of Transportation to adopt, within 3 months, the then existing State safety standards for gas pipelines as interim regulations and to establish, within 24 months, minimum Federal safety standards. The interim standards were issued on November 7, 1968, as Part 190 of Title 49 of the Code of Federal Regulations and became effective on December 13, 1968. With the adoption of these minimum Federal standards in Part 192, the interim standards are no longer necessary. Therefore, the interim standards are revoked on the date that Part 192 becomes effective, except for those provisions applicable to design, installation, construction, initial inspection, and initial testing of new pipelines which will remain in effect until March 13, 1971.
