Every year, thousands of miles of new utility lines are placed underground in the Commonwealth, and proper separation during installation is essential to the safe operation and maintenance of these underground utility lines. Installing a utility line without proper separation poses a threat to the health, safety, and welfare of the people of the Commonwealth and the environment.

At a minimum, persons installing underground utility lines are encouraged to review the following laws, rules, documents and standards that address utility line separation and comply with the requirements and standards when applicable.

Additionally, inquire with the locality where new utility lines are to be placed underground about any local codes, standards, or regulations that specify minimum separation distances.
