Tibbs and Roedder:\nThis responds to your letter of February 22, 1974, regarding the installation of plastic gas main,\nelectric cables, and telephone facilities in the same trench.\nThe Federal standards governing installation of a gas main are set forth in 49 CFR Part 192.\nSubparts G of the standards contain various construction requirements written, for the most part,\nin performance terms. Problems of installation in a common trench are covered in Subpart G and\nin §192.467 with respect to corrosion control. The standards do not specifically prohibit the type\nof installation you describe, but it must meet all applicable requirements in Part 192.\nThe Missouri Public Service Commission is responsible for enforcing the Federal standards as to\nintrastate pipeline facilities in Missouri operated by public utilities other than a municipality. If\nyou have information that Federal requirements are being violated, it should be reported to the\nCommission in the case of a privately owned utility, or to us in the case of a municipality. The\nOccupational Safety and Health Administration of the Department of Labor may also have\nregulations for the safety of employees at the installation.\nIf we may be of further assistance in this matter, please let us know.\nSincerely,\nJoseph C. Caldwell\nDirector\nOffice of Pipeline Safety\ndal\\192\\467\\74-03-18\n1","truncated":false,"body_characters":1572}
