39 Miss. Code. R. 3-1-4

100. MAINTENANCE AND OPERATION OF FACILITIES Each utility shall have and maintain its entire system in such condition and will furnish reasonably adequate and efficient service. Each utility shall inspect its plant and other facilities in such manner as may be necessary to afford a reasonable knowledge as to their condition and adequacy. Such records shall be kept on the conditions found as the utility itself shall consider necessary for the proper maintenance of the system unless in special cases a more complete re cord is specified by the Commission.

105. SYSTEM RECORDS Each utility shall keep a record of the operations of its system, which, insofar as practicable, shall show the units of service made, purchased, sent out, fuels and other raw materials used, and the length of time each producing unit is in operation. The utility shall also keep, insofar as practicable, a record of such details of system operation as may be necessary to substantially reproduce its operations.

110. INDUCTIVE EFFECTS Power supply and communication companies shall cooperate and use all reasonable means to minimize inductive effects between power and communication circuits and to work out those general coordinated methods which are mutually applicable to power and communication systems. (Also See Rule No. 46)

115. MAPS

1. Each utility shall keep and maintain reasonably adequate maps, plans, and records showing the principal layout of every generating or producing plant and of each principal compressing, boosting or substation with the location size, and character or principal items of plant equipment, pipelines, connections, conductors, and other facilities used in the production and delivery of service.

2. Each utility shall keep and maintain reasonably adequate maps, plans, and records of its distributing system, showing the size, character, and location of each main or district regulator, street valve and drip, substation and conductor, together with such other information as will enable the utility promptly and accurately to advise prospective customers and others entitled to inquire as to its facilities available for serving any locality, Where the utility has only inadequate plans of existing facilities, special surveys to locate such facilities will not ordinarily be required, but the utility shall endeavor to keep its records complete by making entries whenever its operations disclose the location of facilities not already accurately recorded.

120. REPORTS TO COMMISSION Each utility shall, upon request of the Commission, file with the Commission a statement regarding the condition and adequacy of its plant, equipment, and facilities, and of its operations and service in such form as the Commission may request.

125. CHANGES IN CHARACTER OF SERVICE Each utility shall notify the Commission, in writing, at least 30 days prior to taking any action in regard to making any major change in the character of service rendered to its customers.

130. EXTENSIONS, REPAIRS, AND IMPROVEMENTS Within the limits of authority conferred upon it by law, the Commission may, upon its own motion or upon complaint and after proper hearing, require a utility to make repairs, improvements to or changes in, any main or line or additions or extension and should reasonably be made in order to promote the public convenience and necessity, or in order to secure reasonably adequate service of facilities.
