(A) Definitions. For purposes of this
		  rule, and this rule only, the following applies:
(1) "A utility"
			 is:
(a) An electric light company as defined by division (C) of
				section 4905.03 of the Revised Code;
(b) A gas company or a natural gas company, as defined by
				divisions (D) and (E) of section 4905.03 of the Revised Code, having more than
				five thousand customers; or
(c) A water-works company or sewage disposal system, as defined
				by divisions (G) and (M) of section 4905.03 of the Revised Code, having more
				than five thousand customers.
(2) "An
			 applicant" is a person, partnership, corporation, association, or
			 organization that makes an application or requests electric, gas, water, or
			 sewage service from a utility. An applicant includes those persons or entities
			 who are currently a customer and are seeking to receive service at another or a
			 new location and those persons or entities who already receive one type of
			 utility service (e.g., electric or water) and want to receive another type of
			 utility service (e.g., gas or sewer) at the same or a different
			 location.
(3) "An eligible
			 customer" is a customer who, based on the information available to the
			 utility, may meet or may become able to meet the criteria or terms and
			 conditions of service of a particular tariff offering or rate schedule. For
			 example, if an electrical residential load management schedule were open to
			 electric residential customers with a monthly minimum demand of four kilowatt
			 hours, an eligible customer would be any residential customer regardless of his
			 or her historical monthly level of demand. Likewise, if a rate schedule were
			 available to any residential electric customer with an electric water heater,
			 all residential customers would be eligible customers. In these two examples,
			 all residential customers are eligible customers (although many of these
			 eligible customers may not actually qualify to receive service under these
			 tariffs) because they may meet or may become able to meet the criteria or terms
			 and conditions of service. However, if an industrial or commercial rate
			 schedule were changed or modified, residential customers would not be
			 considered as eligible customers.
(4) "Disclose"
			 means to inform by use of a brief, one-to-four-sentence (more if necessary)
			 message contained on a bill, on a bill insert, or in a special mailing. A
			 utility may supplement the disclosure by a notice published in a newspaper or
			 newspapers of general circulation in the service territory of the utility. The
			 disclosure must state:
(a) That a new rate is available or that the criteria or terms
				and conditions of an existing rate schedule have been modified;
(b) The nature of the new rate schedule or the modification of
				the existing rate schedule;
(c) That further information can be obtained by calling or
				writing a specific telephone number or address.
(5) "Changes in the
			 criteria or terms and conditions of service" includes all authorized
			 modifications in a particular tariff schedule or offering except for increases
			 and decreases in the base rate, emergency or excise tax surcharge, or the gas
			 cost recovery rate.
(6) "Explanation of
			 the rates, charges, and provisions applicable to the service furnished or
			 available" means a brief summary of the effective rates and the
			 distinctive character of service which distinguish this rate schedule from an
			 alternative one. The explanation may:
(a) Include a typical bill summary and a brief listing of the
				characteristics of the service or criteria which must be met in order to
				qualify to receive service under this schedule;
(b) Be oral or written; however, if the customer or applicant
				specifically requests a written explanation, the utility must provide a written
				explanation.
(B) Duty to disclose.
(1) Within ninety days
			 after a new rate schedule becomes effective, or within ninety days after
			 modifications or changes in the criteria or terms and conditions of service of
			 an existing tariff schedule or offering become effective, the utility shall
			 disclose to the eligible customers the availability of the new tariff schedule
			 or the fact that the criteria or terms and conditions of service of such an
			 existing tariff have changed. A copy of such notice shall be filed with the
			 public utilities commission prior to its distribution to
			 customers.
(2) Upon the request of
			 any customer or applicant, the utility shall provide an explanation of the
			 rates, charges, and provisions applicable to the service furnished or available
			 to such customers or applicant, and shall provide any information and
			 assistance, such as the availability of alternative tariff schedules, necessary
			 to enable the customer to obtain the most economical utility service conforming
			 to his or her stated needs. Nothing in this rule may be construed so as to
			 delay the prompt initiation of service if requested by an
			 applicant.
