(a) On or before May 31, 1978, all gas corporations and gas and electric corporations shall file with the commission tariff provisions which provide that, except in extreme and unusual circumstances or where a customer requests otherwise, such corporations shall reconnect service; during the months of November, December, January, February and March, to any disconnected residential customer no more than 24 hours after any of the following events:
(1) receipt by the gas corporation of the full amount due (to include arrears; reestablishment charges and associated taxes; collection charges and associated taxes; and a security deposit when requested in writing) for which service had been disconnected;
(2) agreement by the gas corporation to a plan by which the residential customer is obliged to satisfy the arrears; or
(3) direction by the commission or chief - Consumer Services Section, Power or Gas Division of the commission staff, or their designees.
(b) The direction to reconnect service under subdivision (c) of this section should only occur where it reasonably appears, in exceptional circumstances, that there is a legitimate dispute about an unpaid portion of the arrears claimed by a utility, where an apparent error in the disconnection of service has occurred, or where a serious impairment to human health or safety seems to exist.
