Title 20 — Subtitle 85. Construction of Underground Electric and Communication Facilities for Residential and Non-Residential Customers

After August 28, 1969, extensions of electric distribution lines on applicants' owned and leased properties, and in industrial parks, necessary to furnish permanent electric service to new commercial and industrial buildings, and to new multiple-occupancy buildings shall be made underground.

These regulations do not apply to extensions of lines of nominal 33,000 volts and higher.

The application of these regulations is not mandatory for extensions of lines to provide electric service to customers whose premises are so unesthetic that the construction of underground lines would serve no purpose. Customers of this nature might include gravel pits and other mining operations, junk yards, railroad yards, and steel mills.

In this chapter, the following terms have the meanings indicated.

Terms Defined.

Rights-of-way and easements suitable to the utility shall be furnished at no cost to the utility by the applicant in a reasonable time to meet service requirements, shall be cleared of trees, tree stumps, and other obstructions at no charge to the utility, and shall be graded to within 6 inches of final grade by the applicant before the utility will commence construction. The clearance and grading shall be maintained by the applicant during construction by the utility.

If, subsequent to construction, the clearance or grade is changed in such a way as to require relocation of the underground facilities, the cost of the relocation shall be borne by the applicant or his successor.

Upon receipt of a proper application, the utility shall install an underground extension with sufficient capacity and suitable materials which, in its judgment, will assure that the applicant, or customer, will receive safe, adequate, and reasonable electric service to meet his requirements.

The design and construction of the underground extension shall conform to accepted good engineering practice in the electric industry to provide an installation at reasonable cost, consistent with the objectives of §A of this regulation.

If the applicant demands an installation more costly than that normally furnished by the utility to meet the objectives of §B of this regulation, then the applicant shall pay the cost of his additional requirements.

Rights-of-way and easements in accordance with Regulation .03 of this chapter;

Required suitable conduit systems, including conduits or raceways within a building on the line side of the meter;

Required suitable transformer vaults and entrance facilities;

Required suitable enclosures for switching and protective equipment; and

All equipment and facilities, other than those specified above, required by the utility's rate schedule for the type of service received.

The utility shall construct a connection from the utility's existing supply facilities to the underground extension in accordance with the extension rules of the utility on file with the Commission.

An electric company may not permit any person not a public service company to make attachment to any electric company existing overhead facilities for the purpose or intended purpose of providing overhead service to a customer to whom the electric company is required to provide underground service in accordance with the regulations of the Commission with respect to underground service.

To the extent practicable, electric cables, communications cables, and gas pipes shall be installed in the same trench, care being taken to conform to any applicable code and utility specification.

Upon timely application, an electric company shall allow any person precluded from using overhead facilities as set forth in Regulation .08B, of this chapter, joint use of its open trenches wherever reasonable and technically feasible in accordance with mutually agreeable terms and conditions.

After August 28, 1969, extensions of telephone distribution lines on applicants' owned and leased properties, and in industrial parks, necessary to furnish permanent telephone service to new commercial and industrial buildings and to new multiple-occupancy buildings, shall be made underground.

The application of these regulations is not mandatory for extensions of lines to provide telephone service to customers whose premises are so unesthetic that the construction of underground lines would serve no purpose. Customers of this nature might include gravel pits and other mining operations, junk yards, railroad yards, and steel mills.

Extensions of electric distribution lines made after June 5, 1968, which are necessary to furnish permanent electric service to new residential buildings and mobile homes, shall be made underground. The extensions of service shall be made by the utility in accordance with the provisions in these regulations.

These regulations apply to:

In this chapter, the following terms have the meanings indicated.

Terms Defined.

“Underground electric distribution system” means that portion of an electric utility distribution plant necessary to furnish permanent underground service to all present and anticipated residential buildings and mobile homes in a subdivision. The system includes underground electric service lines as defined in §B(9) of this regulation.

“Underground electric service line” means that portion of an electric utility distribution plant necessary to furnish permanent underground service from the lot line to a residential building or mobile home.

“Utility” means an “electric company” stated in Public Utilities Article, §1-101, Annotated Code of Maryland.

The utility shall construct, own, operate, and maintain an underground electric distribution system only along public streets, roads, and highways which the utility has the legal right to occupy, and on public lands and private property across which rights-of-way and easements satisfactory to the utility may be obtained without cost or condemnation, in reasonable time to meet service requirements.

Rights-of-way and easements shall be cleared of trees, tree stumps, and other obstructions at no charge to the utility, and shall be graded to within 6 inches of final grade by the applicant before the utility will commence construction. The clearance and grading shall be maintained by the utility.

If, subsequent to construction, the clearance or grade is changed in such a way as to require relocation of the underground facilities, the cost of the relocation shall be borne by the applicant or his successor.

Upon receipt of a proper application, the utility shall install, own, and maintain an underground electric distribution system or underground electric service line with sufficient capacity and suitable material which, in its judgment, will assure that the applicant will receive safe, adequate, and reasonable electric service for the foreseeable future.

If the underground electric distribution system is to be installed in a subdivision, the applicant shall furnish the utility as required, at no charge, property plats, utility plans, grading plans, roadway profiles, and other items showing details of proposed construction within the applicant's subdivision in reasonable time to allow the utility to engineer, design, and construct its facilities in a safe and efficient manner to meet service requirements and to comply with applicable laws, codes, and regulations.

The service connection to the building normally will be at the corner of the building nearest the point at which the underground electric service line enters the property to be served.

Each applicant will cooperate with the utility in an effort to keep the cost of construction and installation of the underground electric distribution system or service line as low as possible. Additional costs arising from failure of the applicant to cooperate with the utility, such as his making changes in grade or failing to maintain grade, shall be borne by the applicant.

If an underground installation is to be constructed within a subdivision designed to include large open areas which would result in an abnormal increase in the investment per customer required to construct the underground distribution system, then the utility may refer the matter to the Commission for a ruling as to whether a charge should be assessed against the applicant, and the amount of the charge, if any.

For underground electric distribution systems installed in subdivisions, the utility shall construct a connection from the boundary line of the applicant's subdivision to the utility's existing supply facilities, subject to the following provisions:

For underground electric service lines to new residential buildings or mobile homes for which §A of this regulation is not applicable, the utility shall construct an underground line from the lot line of applicant's property to the existing underground or overhead line on either side of the street or road in front of the lot, at no charge to the applicant. If there is no electric supply facility or overhead facilities of another public service company which may be jointly shared along the street or road at that location, then the utility shall construct an underground line to the nearest practicable existing electric supply facilities in accordance with the provisions of the regular extension rules in the tariff of the utility on file with the Commission. However, any charge or deposit to the applicant may not exceed the equivalent of $1 per foot of line extension not on applicant's property, subject to appeal to the Commission under Regulation .10, if this should appear to be impracticable.

An electric company may not permit any person not a public service company to make attachment to any electric company existing overhead facilities for the purpose or intended purpose of providing overhead service to a customer to whom the electric company is required to provide underground service in accordance with the regulations of the Commission with respect to underground service.

When, due to the manner in which a subdivision is developed, the utility is required to construct an underground electric distribution system through a section or sections of the subdivision where service will not be connected for at least 2 years, then the utility may require the applicant to make a reasonable deposit before construction is commenced. The deposit may be no more than the estimated installed cost of the underground distribution system less the estimated installed cost of transformers and meters.

The deposit, without interest, shall be returned to the applicant on a proportional basis as each new customer in the subdivision completes his permanent service connection.

Any portion of a deposit remaining unrefunded 10 years from the date the utility is first ready to render service from the extension will be retained by the utility and credited to an appropriate account.

Each utility engaged in underground construction shall cooperate to the extent practicable in having information available for review by other utilities concerning applicants for new services.

To the extent practicable, electric cables, communications cables, and gas pipes shall be installed in the same trench, due care being taken to conform to any applicable code and utility specification.

Upon timely application, an electric company shall allow any person precluded from using overhead facilities as set forth in Regulation .06C of this chapter, joint use of its open trenches wherever reasonable and technically feasible in accordance with mutually agreeable terms and conditions.

In unusual circumstances, when the application of these regulations appears impracticable or unjust to either party, or discriminatory to other customers, the utility or applicant may refer the matter to the Commission for modification of the regulations or for the approval of special conditions before commencing construction.

Requests to the Commission for exemption from the requirements for underground installation of an electric distribution system or a service line shall be in writing and shall include the following:

Extensions of telephone distribution lines made after June 5, 1968, which are necessary to furnish permanent telephone service to new residential buildings and mobile homes, shall be made underground.
