Dear Mr. Anderson:

This is in response to your letter dated July 5, 1972, regarding requirements for producing or maintaining maps.

Your specific question asked whether there was any requirements for producing or maintaining maps of gas transmission or distribution systems.

Section 192.603(b) requires that each operator shall establish a written operating and maintenance plan meeting the requirements of the Federal gas safety regulations and keep records necessary to administer the plan. If an operator requires maps as a record to properly administer the operating and maintenance plan to meet the Federal safety requirements, then these maps must be maintained by the operators.

We trust that this has answered your specific question. If we can be of further assistance, please let us know.
