Johansen\nAssistant Director, Gas Department\nEngineering Section\nMissouri Public Service Commission\nP.O. Box 360\nJefferson City, Missouri 65102\nDear Mr. Johansen:\nWe regret the delay in answering your letter about a compliance issue involving the Laclede Gas\nCompany.\nAs we understand your inquiry, it is whether Section 3(a)(1) of the Natural Gas Pipeline Safety\nAct of 1968, as amended (49 USC 1672(a)(1)), permits retroactive application of the cathodic\nprotection standards in Subpart I of Part 192 to pipeline facilities in existence when the standards\nwere adopted.\nSection 3(a)(1) provides that standards applying to emergency plans and procedures, extension,\noperation, replacement, maintenance, subsequent inspection, or subsequent testing may be applied\nto pipeline facilities in existence when the standards are adopted. With respect to existing\nfacilities (installed before August 1, 1971), Subpart I requires the determination of areas of active\ncorrosion and the application of cathodic protection to these areas and to any repaired or replaced\nareas, with subsequent inspection and testing to ascertain whether the cathodic protection is\nworking properly. These requirements are examples of standards specifically permitted by\nSection 3(a)(1) for replacement, maintenance, inspection, and testing of existing pipeline facilities.\nThey are not standards which would require modification of a pipeline's design to achieve\ncompliance; and we agree that such standards would be forbidden by Section 3(a)(1).\nSincerely,\nMelvin A. Judah\nActing Associate Director for\nPipeline Safety Regulation\nMaterials Transportation Bureau\ndal/192.457\n82-06-30","truncated":false,"body_characters":1694}
