Alexander\nProject Engineer\n320 Hughes Street\nHouston, Texas 77011\nDear Mr. Alexander:\nThis is in reply to your letter of February 17, 1971, concerning the interpretation of 49 CFR,\nSection 192.145(a).\nPublished specifications do not exist for all types and sized of valves that are manufactured;\nhowever, there are certain basic safety design features that can be adapted to all these valves.\nThe word \"equivalent\" is used in the sense of providing equivalent safety. For example, the listed\nspecifications do not cover all sizes and types of valves, but a valve of a size or type not covered\nshould at least meet the applicable safety requirements in the listed specifications.\nThank you for your interest in the pipeline safety program.\nSincerely,\n/signed/\nJoseph C. Caldwell\nDirector, Acting\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\145\\71-03-05\n1","truncated":false,"body_characters":888}
