§ 57.11. Accidents.

 (a)  General. A public utility shall submit a report of each reportable accident involving the facilities or operations of the public utility in this Commonwealth to the Secretary of the Commission.

 (b)  Reportable accidents. Reportable accidents are those involving utility facilities or operations which result in one or more of the following circumstances:

   (1)  The death of a person.

   (2)  Injury to an employe on duty sufficient to incapacitate him from performing his ordinary duties for a period longer than 3 days.

   (3)  Injury to a person other than an employe on duty sufficient to incapacitate the injured person from following his customary vocation, or mode of life, for a period of more than 1 day.

   (4)  An occurrence of an unusual nature, whether or not death or injury of a person results, which apparently will result in a prolonged and serious interruption of normal service.

 (c)  Telegraphic reports. A report by telephone or telegraph shall be made at once in the event of the occurrence of a reportable accident resulting in the death of a person or in an occurrence of an unusual nature.

 (d)  Written reports. A written report shall be made on Form UCTA-8 immediately following the occurrence of a reportable accident. Accidents reportable on forms required by the Bureau of Workmen’s Compensation, Pennsylvania Department of Labor and Industry, may be reported by transmitting a copy of such reports in lieu of a report on Form UCTA-8.

 (a)  Investigations. A public utility shall make a full and prompt investigation of complaints made by its customers, either directly to it or through the Commission.

 (b)  Record of complaints. A public utility shall preserve written electric service complaints showing the name and address of the complainant, the date and nature of the complaint, the action taken and the date of final disposition.

 (a)  Standard voltage. A public utility shall adopt a standard nominal service voltage for the entire territory served by the public utility, and shall file with the Commission data on such standard service voltage or voltages as part of its officially filed tariff. The suitability and adequacy of the standard nominal service voltage or voltages adopted may be determined at any time by the Commission.

 (b)  Allowable voltage variation (primarily lighting). For service rendered primarily for lighting purposes, the allowable variation in voltage measured at the service terminals of the customer may not exceed, for a longer period than 1 minute in each instance, 5% above or below the standard nominal service voltage and a total variation from minimum to maximum of 8% during normal system operation.

 (c)  Allowable voltage variation (primarily power). For service rendered primarily for power purposes, the allowable variation in voltage measured at the service terminals of the customer may not exceed, for a longer period than 1 minute in each instance, 10% above or below the standard nominal service voltage during normal system operation.

 (d)  Variation in excess of allowable limits.

   (1)  A public utility may, if approved by the Commission, furnish service under conditions of greater voltage variations if there is a filing of the following with the Commission:

     (i)   A copy of existing contracts containing a provision for the supply of service with such greater variations of voltage.

     (ii)   A copy of contracts made which contemplate the supply of service under conditions of greater voltage variations and which in each case contain a clause stating the probable variations in voltage which will occur in the service rendered under such contract, and further that such greater variations in voltage will not result in unreasonable discrimination in favor of or against any customer.

   (2)  Variations of voltage in excess of those specified, caused by the operations of the facilities of the customer in violation of his contract or the filed tariff rules of the public utility, or from causes beyond the control of the public utility, will not be considered as violations of this section.

 (e)  Records. A public utility shall keep in continuous operation at least one graphic recording voltmeter on each primary network system or on at least one circuit from each substation supplying more than 1,000 customers. These meters shall be installed either at the substation or near the load center of such area or circuits. The hourly readings of indicating voltmeters recorded at points of supply, such as generating stations and main transmission or distribution substations where attendants are regularly on duty, shall constitute a satisfactory voltage record. A public utility shall also install additional graphic recording voltmeters at such places and for such periods of time as the Commission may require.

   Contractor cost—The amount paid by a public utility to a contractor for work performed on a line extension.

   Direct labor cost—The pay and expenses of public utility employes directly attributable to work performed on line extensions, but does not include construction overheads or payroll taxes, workmen’s compensation expenses or similar expenses.

   Direct material cost—The purchase price of materials used for a line extension, but does not include related stores expenses. In computing direct material costs proper allowance should be made for unused materials, materials recovered from temporary structures, and discounts allowed and realized in the purchase of materials.

   Maximum extension distance—The distance in feet below which a public utility will provide a line extension without imposing a charge on or requiring a revenue guarantee from the customer requesting the extension.

 (b)  Duty to make line extensions. The public utility shall make line extensions within the territory in which it is authorized to operate.

 (c)  Tariffs to include line extension rule. The public utility shall file with the Commission as part of its tariffs a rule setting forth its maximum extension distance for single-phase line extensions and the conditions under which it will make the line extensions beyond this distance. The rule shall also include a plan whereby the public utility will construct, operate, and maintain single-phase and polyphase line extensions required to serve customers who will guarantee revenues in an amount sufficient to comply with the requirements set forth in the rule, and a statement of the terms upon which the guarantee shall be reduced to the minimum charges as provided in the rate schedules applicable to each class of service supplied.

 (d)  Determination of guarantees for single-phase line extensions. The amount of revenue to be guaranteed and subsequent changes thereto shall be determined solely on the basis of contractor costs, direct labor costs and direct material costs attributable to the construction of the line extension beyond the maximum extension distance. Appropriate adjustments shall be made at least annually in the amount of revenue guaranteed by a customer by reason of change in the number or classification of customers supplied from the line extension. The amount of costs attributable to the construction of a line extension below the maximum extension distance may be determined by multiplying the cost of the line extension by the percentage of distance of the line extension below the maximum extension distance.

 (e)  Determination of guarantees for polyphase line extensions. In determining the revenues originally to be guaranteed and subsequent changes, the following conditions shall be applicable, as appropriate:

   (1)  Guarantees of revenue shall be based upon the total construction cost to the public utility of the line extension.

   (2)  Guarantees of revenue shall be based upon the length of pole line required to furnish service.

   (3)  Guarantees shall be based upon a reasonable plan by which the construction cost, length of line extension, or number of customers served or to be served from the line extension are given consideration.

   (4)  Appropriate adjustments shall be made at least annually in the amount of revenue guaranteed by the customer by reason of change in the number or classification of customers supplied from the line extension.

 (f)  Service to additional customers. Additional customers shall be connected to a line extension of a line already built or to a further extension of a line only upon the same terms and conditions as would apply if the extension were being made for customers including the new customers, if the inclusion of new customers would not increase the guarantees of the existing customers. If the guarantees of existing customers would be increased, the line extension constructed to serve additional customers shall be considered and treated as a new and separate line extension for these additional customers.

 (g)  Wiring and equipment of customers. Wiring and equipment on the premises of the customer shall be installed to conform with the rules and standards established by the public utility. The customer shall provide poles, wires and other construction necessary to bring the terminus of the customer’s installation to a location where it may be connected to a line extension by means of a service line.

 (a)  Average meter error. In meter tests made by the public utility or by the Commission at the request of a customer, the correctness of adjustment of the meter and its performance in service shall be judged by its average error, determined as follows:

   (1)  If the meter is used to measure a load which is substantially constant, the meter shall be tested at that load. The error of the meter at the constant load shall be accepted as the average meter error.

   (2)  If the meter is used to measure a variable load, the average error shall be obtained by taking 1/5 of the algebraic sum of both of the following:

     (i)   One part of the error at light load.

     (ii)   Four parts of the error at heavy load.

   (3)  If, in the opinion of the Commission, another load is more representative of the average operating load, the error of the meter at the average operating load will be accepted as the average meter error.

 (b)  Fast meters. If, upon testing, a meter is found to have an average meter error of more than 2% fast, the public utility shall refund to the customer the overcharge, based upon the corrected meter reading for a period equal to 1/2 the time elapsed since the last previous test, but not to exceed 12 months. If the period of registration error is definitely fixed, the overcharge shall be computed for the period. If the meter has not been tested in accordance with §  57.20 (relating to watthour meter testing), the period for which it has been in service beyond the regular test period shall be added to the 12 months in computing the refund.

 (c)  Slow meters. If, upon testing, a meter is found to have an average meter error of more than 2% slow, the public utility may render a bill for the service furnished, but not covered by bills previously rendered, for a period equal to 1/2 the time elapsed since the last previous test, but not to exceed 3 months. If the period of registration error is definitely fixed, the charge may be computed for the period.

 (d)  Access to meters. The public utility shall, at reasonable times, have access to meters, service lines and other property owned by it on premises of customers, for purposes of maintenance and operation. Neglect or refusal on the part of customers to provide reasonable access to their premises for these purposes is deemed to be sufficient cause for the discontinuance of service.

Immediately after making final adjustment, the tester shall seal and date tag the reference standard and shall furnish the public utility with a correction curve properly dated and signed.

 (c)  Periodic tests of watthour standards. The portable watthour standards, together with other measuring equipment the Commission may require, shall also be tested and adjusted periodically by a representative of the Commission if necessary as the Commission may direct. The tester shall furnish the public utility with a correction curve properly dated and signed.

 (d)  Frequency of portable watthour standard check tests. During the interval between tests by the Commission, the portable watthour standards shall be compared with the reference standard at least every month for induction type meters, and every 3 months for the solid state meter standards. The calibration obtained shall be used in determining the accuracy of the service meters. If a portable standard is subject to either a mechanical or electrical shock, it shall be tested before being used.

 (e)  Records of check tests and correction curves. A record of check tests shall be kept showing the condition and accuracy of the watthour standard before and after testing, indicated by the words ‘‘as found’’ and ‘‘as left,’’ in form and detail to permit convenient checking of the methods and results.
