These rules describe the enforcement authority and procedures to achieve and maintain gas pipeline and transportation safety within the State of Vermont. They also prescribe the sanctions which may be requested by the Department of Public Service and imposed by the Vermont Public Utility Commission for safety violations.
These Rules cover the design, construction, installation, operation, maintenance, testing, inspection, and safety features of gas transmission and distribution systems, including gas storage, metering and regulating stations, mains and services up to the outlet of the customer's meter assembly, or outside the building wall, whichever is further downstream.
These Rules and Regulations shall be complied with in all new installations but shall not apply retroactively to existing facilities except where specifically indicated or if the Public Utility Commission determines that existing equipment or operations are hazardous to the public.
These Rules and Regulations shall apply to every person, firm, company, corporation and municipality engaged in the construction or operation of any gas transmission or distribution system in the State of Vermont which is or shall become subject to the jurisdiction of this Commission.

These Rules and Regulations shall apply to every person, firm, company, corporation and municipality engaged in the construction or operation of any gas transmission or distribution system in the State of Vermont which is or shall become subject to the jurisdiction of this Commission.
The definitions in effect as of the date of the adoption of the rules, and as they may thereafter from time to time be amended, contained in the regulations of the Transportation of Natural and Other Gases by Pipeline, parts 191, 192, 193, 198, and 199, Title 49, The Code of Federal Regulations, as in effect as of the effective date of these Rules, shall apply.
"Gas Corporation" shall mean any person, firm, company, corporation or municipality engaged in the transmission or distribution of gas by a piping system.
"Federal Regulations" shall mean the regulations of the Transportation of Natural and Other Gases by Pipeline, parts 191, 192, 193, 198, and 199, Title 49, Code of Federal Regulations and any subsequent revisions.
"Commission" shall mean the Public Utility Commission of the State of Vermont.
Upon its own motion, or upon application, and for good cause shown, the Commission may modify, suspend or repeal the provisions of any rule herein, provided the modification, suspension, or repeal does not violate the Federal Regulations. Only in the case of an emergency may these regulations be waived. Application may be made to the Commission for modification of any rule or for temporary or permanent exemption from its provision. However, in instances where the requested modification or exemption would also require a departure from the applicable Federal Regulations, such application also must be submitted to the Office of Pipeline Safety. A copy of the Office of Pipeline Safety decision shall be submitted to the Public Utility Commission. Such an application for modification for exemption must be accompanied by a full and complete justification for the proposed change.
Every gas transmission or distribution system shall be constructed, tested, and operated, except as otherwise provided in these Rules, in compliance with the provisions of the presently effective Federal Regulations and any future revisions of that code. When the regulations stated in these Rules are more stringent than the Federal Regulations, provisions in these Rules shall apply; if the provisions as stated in these Rules are less stringent than the Federal Regulations, the Federal Regulations shall take precedence.
Gas service piping up to the entry of the first building downstream of that customer, or, if the buried pipe does not enter a building, up to the principle gas utilization equipment or the first fence (or wall) that surrounds that equipment, shall be installed and maintained pursuant to these Rules and the Federal Regulations. However, for a customer-owned service line, as defined in the Federal Regulations, for an industrial application, responsibility for compliance with these Rules and the Federal Regulation resides with the industrial customer.
For a customer-owned service line, as defined in the Federal Regulation, the Gas Corporation may assess the reasonable cost of complying with this section to the customer owning or using such customer-owned service line. Such assessment must be reviewed and approved by the Commission pursuant to a tariff filing under 30 V.S.A. §§ 218, 225, 226, and 227.
Curb shut-offs, usable in an emergency to shut off the supply of gas, shall be installed on all high-pressure gas services whenever the regulator is located within the customer's premises and on all low-pressure gas services whenever gas is supplied to a building where the public assembles, e.g., a school or theater.
Curb shut-offs shall be inspected at reasonable intervals, and when such devices are located on services supplying a building where the public assembles, e.g., a school or theater, they shall be inspected by the Gas Corporation at least once each year.
All gas service piping not requiring a curb shut-off pursuant to Federal Regulations shall have a device installed to cut off the gas outside the cellar wall area, whenever service has been discontinued for a period in excess of twelve (12) consecutive months. A service line that has been disconnected for a period of five (5) years or longer must be physically disconnected at the main.
This physical disconnection may be waived if the service line was built after July 31, 1971, and it is being maintained as if it is an active service line.
Upon request of the Commission or Department of Public Service, the Gas Corporation shall file with the Commission and the Department of Public Service a complete set of maps of the requested area showing the location of the pipes and grids, pipe sizes, operating pressures, valves, regulator stations, and other pertinent data showing that the transmission or distribution system has been constructed or reconstructed in accordance with these Rules.
Upon request by the Commission or the Department of Public Service, a report setting forth the specifications, including application of other design criteria, of the construction or the reconstruction of any gas transmission or distribution system, shall be filed with the Commission and the Department of Public Service.
In the event of a failure of service of gas transmission or a major failure of service of a distribution system, immediate notice shall be given to the Department of Public Service, by telephone or other means of prompt notification to be followed by a written report to the Department of Public Service and the Commission. Such written report shall contain all pertinent information known to the Gas Corporation concerning the cause of the failure and the steps proposed or taken to remedy the defect, and shall be submitted within 30 days of the service failure. This requirement shall not apply to any interruptions of service made by a Gas Corporation in accordance with the provisions of contracts between such corporations and their customers.
Accidents occurring on gas transmission or distribution systems and facilities and causing in- patient hospitalization or death to any person or persons, or damage to property in excess of $ 5,000, shall be reported immediately to the Commission and Department of Public Service by telephone or other means of prompt notification
Every Gas Corporation operating a gas transmission or distribution system in the State of Vermont shall file with the Department of Public Service and the Commission and with every municipality within which the gas transmission distribution system is located, the names, addresses and telephone numbers of two responsible officials of such gas corporations who may be contacted in the event of an emergency.
When specifying materials for gas transmission pipelines, current industry standards, including criteria for pipe fracture toughness shall be considered.
Within 12 months of the effective date of these Rules, or sooner if required, as a condition of a certificate of public good under 30 V.S.A. §§ 102 and 231, a program shall be adopted by every Gas Corporation to keep to a minimum the amount of gas that is lost or unaccounted for. Gas Corporations shall file an annual statement with the Department of Public Service of the Gas Corporation's gas unaccounted for.
Upon notice from the Commission that the twelve-month rolling average of gas unaccounted for by a Gas Corporation appears to exceed the national average, and if upon examination the Commission determines that the actual amount unaccounted for does actually exceed the national average, such Gas Corporation within ninety (90) days of such determination, shall state in writing its plans for reducing this unaccounted for gas. In addition, such Gas Corporation shall file a report every three (3) months thereafter of its progress in reducing that unaccounted for gas until the Commission, by further Order, dispenses with this reporting requirement.
When natural gas is to be introduced into a distribution system previously used to supply manufactured gas to customers, appropriate measures shall be taken before the introduction of natural gas to prevent drying out of joints and the formation of dust within the mains.
Consideration should be given to installations of fogging and dust collecting equipment as well as application of sealing compounds prior to the change to natural gas. Routine tests normally made to detect gas leaks in the distribution system shall be intensified for a reasonable period following the conversion to natural gas to facilitate prompt discovery and repair of gas leaks.
All of the above state and federal statutes shall be effective in their present and any future revisions. This Rule supersedes General Order No. 59.63 dated May 5, 1977, and General Order No. 41 dated February 1, 1965.
