In determining what measures may be necessary, you should consider\nthe types and magnitudes of all anticipated external forces which may be applied to the pipeline\nduring and after the road construction. Various causes of external forces, which you should\nconsider include: unstable soils, floods, traffic, movement by heavy construction or maintenance\nequipment, and direct damage by construction equipment.\nDB\nC:\\WP51\\INTERPRT\\192\\613\\75-11-01\n1\n\n<<<PAGE 2>>>\n\n\"If it is decided that a portion of the pipeline should be replaced, relocated, or otherwise changed\nto protect it against likely external forces, that replacement, relocation, or change must comply\nwith the requirements in 49 CFR Part 192 applicable to design, installation and testing of\npipelines.\nCesar DeLeon\nActing Director\nOffice of Pipeline\nSafety Operations\nDB\nC:\\WP51\\INTERPRT\\192\\613\\75-11-01\n2","truncated":false,"body_characters":2692}
