What standard is generally required for utilities regarding the burying of underground gas lines?

The standard that is generally required for utilities regarding the burying of underground gas lines is the National Fuel Gas Code. This code provides guidelines and requirements aimed at ensuring the safety and proper installation of gas piping and appliances. Specifically, it includes directives about the installation of underground gas lines, covering aspects such as depth of burial, materials that must be used, and protective measures against potential hazards.

The National Fuel Gas Code is essential for ensuring that gas distribution systems do not pose risks of leaks or other dangers that could arise from improper installation or maintenance. By following this code, utilities can help protect public safety and ensure compliance with regulatory requirements.

Other options, like the National Electrical Code, the International Plumbing Code, and the Uniform Mechanical Code, focus on different aspects of electrical, plumbing, and mechanical systems respectively, but they do not address the specific requirements related to gas line installation in the same way that the National Fuel Gas Code does.
