Synthesized answer (unofficial)

UFC 3-430-05 is the Unified Facilities Criteria for Natural Gas and Liquefied Petroleum Gas (LPG) Distribution Pipelines, current as of 26 February 2021 [UFC 3-430-05].

This UFC provides guidance for the design and installation of new or modifications to existing distribution pipelines conveying natural gas, manufactured gas, or LPG [UFC 3-430-05]. It supersedes UFC 3-430-09 (Exterior Mechanical Utility Distribution, dated 16 January 2004) [UFC 3-430-05].

Air Force implementation requires that natural gas and LPG distribution systems comply with UFC 3-430-05, which itself implements DOT Pipeline and Hazardous Materials Safety Administration standards (49 CFR Part 192). LPG systems must additionally comply with NFPA 58, and natural gas interior piping must comply with NFPA 54 [DAFMAN 32-1067 para 8.1.1].

For buried nonmetallic piping, an electrically conductive wire or tape must be buried within 12 inches above the pipe for locating purposes [DAFMAN 32-1067 para 8.1.1].
