Notice of Comment Period on Proposed Regulations Concerning Gas Pipeline Safety and Gas Transmission and Distribution Systems, Including the Commission's Jurisdiction to make and Enforce Rules Required by the Federal Gas Pipeline Safety Act Of 1968, As Amended

The Delaware General Assembly has enacted legislation granting the Delaware Public Service Commission ("Commission") the authority to make and enforce rules required by the federal Gas Pipeline Safety Act of 1968, as amended (49 U.S.C. Chapter 601), to qualify for federal certification of a state pipeline safety compliance program relating to the regulation of intrastate gas pipeline transportation. The new legislation is found at 76 Delaware Laws Ch. 393.

In order to comply with the new legislation, the Commission is promulgating regulations, containing twelve sections, intended to govern the safety of the gas transmission and distribution systems, which are subject to the Commission's jurisdiction. The first section contains definitions of terms used in the regulations, for example, the classification of gas leaks. The second section incorporates by reference the pertinent provisions of Title 49 of the Code of Federal Regulations which contain the minimum federal standards related to matters such as: (1) the design, fabrication, inspection, reporting, and testing of gas transmission and distribution systems; and (2) the drug testing inspection of natural gas pipeline utilities.

Two sections of the new regulations contain requirements for performing gas leak surveys, maintaining gas leak progression maps, and notifying the Commission and the local fire department in the event of gas leaks. One new section addresses Liquefied Natural Gas (LNG) installations, including the adoption of the pertinent standards of Title 49 of the Code of Federal Regulations related to their design, construction, operation, maintenance, protection, and security.

Five sections pertain to Commission procedures which apply to the operators of gas transmission and distribution systems. The five sections include provisions addressing: (1) the delegation of authority to the Commission Staff to carry out the day-to-day oversight of the systems; (2) the informal disposition of probable violations of the regulations; (3) the manner of giving formal notice of probable violations; (4) the response options of operators of the systems when notified of a probable violation; and (5) actions that might be taken by the Commission in the event a violation comes before the Commission for formal resolution.

One of the new sections sets forth the Commission's authority in the event a pipeline facility presents a hazard to life or property. The final provision addresses the Commission's authority to grant waivers from compliance with the federal Gas Pipeline Safety Regulations and the procedures to be followed by the Commission in ruling upon an application by an operator for a waiver.

The Commission has authority to promulgate the regulations pursuant to 26 Del.C. § 209(a), 29 Del.C. §10111 et seq., and 76 Delaware Laws Ch. 393 (2008)(26 Del.C. Ch. 8).

The Commission hereby solicits written comments, suggestions, compilations of data, briefs, or other written materials concerning the proposed regulations. Ten (10) copies of such materials shall be filed with the Commission at its office located at 861 Silver Lake Boulevard, Cannon Building, Suite 100, Dover, Delaware, 19904. All such materials shall be filed with the Commission on or before November 7, 2008. Persons who wish to participate in the proceedings but who do not wish to file written materials are asked to send a letter informing the Commission of their intention to participate on or before October 30, 2008.

The regulations and the materials submitted in connection therewith will be available for public inspection and copying at the Commission's Dover office during normal business hours. The fee for copying is $0.25 per page. The regulations may also be reviewed, by appointment, at the office of the Division of the Public Advocate located at the Carvel State Office Building, 4th Floor, 820 North French Street, Wilmington, Delaware 19801 and will also be available for review on the Commission's website:

7.0 Informal Disposition of Probable Violation

When an evaluation of an operator's records or facilities indicates that the operator is apparently violating these regulations, the Commission Staff will informally discuss the probable violation with the operator before concluding the inspection. Any documentation or physical evidence necessary to support a future allegation of non-compliance may be obtained during the inspection. On-site corrective action may be taken by the operator of the facilities where the probable violation exists, thus correcting the violation without further action.

8.0 Written Formal Notice of Probable Violation

After evidence of a probable violation is collected and the violation report written, notice and opportunity to respond will be afforded the operator by a letter from the Commission Staff notifying the operator of the results of the on-site evaluation and specifically citing the provision of the applicable regulation(s) the operator is apparently violating. A written response from the operator must be filed with the Commission within 10 days of the date the operator receives the violation notice.

9.0 Response Options Open to Operator

9.1 The operator, in responding to the violation notice, may:

9.1.1 Submit a written plan specifying actions that the operator will take to correct the violation, a schedule for completion of each action step, and a final date of compliance. If the Commission Staff accepts the corrective plan submitted by the operator, the violation is resolved.

9.1.2 Request an informal conference with the Commission Staff. Upon request for an informal conference, the Executive Director of the Commission, or the Executive Director's designee, will establish a date, time, and location for the conference. During the conference, Staff will review the violation report with the operator to identify corrective actions and reach a mutually acceptable resolution of the violation. If this effort fails, the Executive Director of the Commission may refer the violation to the Commission for formal action.

10.0 Commission Action

10.1 If the Executive Director of the Commission refers the violation to the Commission for formal resolution, the Commission may take such action as it deems appropriate, including the following:

10.1.1 The Commission may seek injunctive relief in the Delaware Court of Chancery;

10.1.2 The Commission may issue an Order and schedule a hearing requiring the operator to show cause why the operator should not be subject to the penalties provided by law for the violation; and

10.1.3 The Commission may, after investigation and a public hearing, order an operator to take corrective action.

11.0 Hazardous Facility Orders

11.1 If the Commission finds a pipeline facility is hazardous to life or property, the Commission may issue an Order requiring the operator to take immediate corrective action, which may include:

11.1.1 Suspended or restricted use of the facility;

11.1.2 Physical inspection;

11.1.3 Testing;

11.1.4 Repair;

11.1.5 Replacement; or

11.1.6 Other action.

11.2 The Commission shall give the operator written notice and an opportunity for a hearing before issuance of a hazardous facility Order unless the Commission or its Staff determines there is a serious and imminent threat to life or property, in which case, the Commission or its designated hearing examiner, may issue an emergency Order. If the Order is issued without a prior hearing, the Commission shall give the operator written notice and an opportunity for a hearing before the Commission or its designated hearing examiner as soon after the emergency Order is issued as possible.

11.3 The operator may take exceptions from the decision of the hearing examiner as provided by Delaware law. After receipt of the exceptions, the Commission may investigate further and hold a public hearing on the matter within a reasonable time.

12.0 Granting of Federal Regulation Waivers

12.1 Upon application by an operator, the Commission may grant a waiver from compliance with the federal Gas Pipeline Safety Regulations for intrastate pipeline transportation, subject to review by the Office of Pipeline Safety Regulation of the United States Department of Transportation.

12.2 Waivers may be granted for particular circumstances where it is inappropriate for an operator to follow a regulation of general applicability.

12.3 Before granting a waiver, the Commission must give notice and opportunity for written comments and hearing, unless the Commission finds that notice is impracticable, unnecessary, or not in the public interest.

12.4 If the Commission finds a requested waiver is consistent with gas pipeline safety and is otherwise justified, the waiver must be issued under appropriate terms and conditions with a statement of reasons for granting the waiver.

12.5 If the Commission finds a requested waiver is inconsistent with gas pipeline safety or is otherwise unjustified, the request must be denied, and the applicant notified of the reasons for denial.

12.6 The Commission must give the Office of Pipeline Safety Regulation of the United States Department of Transportation written notice of each waiver at least 60 days before it becomes effective. Each notice of waiver must provide the following information:

12.6.1 The name, address, and telephone number of the applicant;

12.6.2 The safety standards involved;

12.6.3 A description of the pipeline facilities involved; and

12.6.4 The justification for the waiver, including the reasons why the standards are not appropriate and why the waiver is consistent with gas pipeline safety.
