PHMSA Liquid Pipeline Final Rule – Low Stress and Gathering Line Exemptions

[Docket ID PHMSA-RSPA-2003-15864]

Effective July 3, 2008, PHMSA has amended its hazardous liquid pipeline safety regulations to:

  • Define “regulated rural gathering line” as an onshore gathering line in a rural area that has a nominal diameter of 6 5/8” to 8 5/8”, located within ¼ mile of an Unusually Sensitive Area (USA), with an MOP greater than 20% of the SMYS (or greater than 125 psi if the SMYS is unknown or the pipe isn’t made of steel); and require operators of these lines to comply with a subset of the existing pipeline safety requirements.
  • Narrow the regulatory exception for rural onshore low-stress hazardous liquid pipelines by extending all existing safety regulations, including integrity management requirements, to low-stress pipelines with a nominal diameter of 8 5/8” or more located within ½ mile of a USA. Operators of newly regulated low-stress pipelines that can show an undue economic burden from complying with all pipeline safety regulations may be able to obtain a special permit from PHMSA to comply with alternative safety requirements in order to keep operating.
  • Require operators of all low-stress pipelines (even those that continue to be exempt), to comply with annual reporting requirements.

These rule modifications were first proposed in a Notice of Proposed Rulemaking on September 6, 2006, and revised by a Supplemental Notice of Proposed Rulemaking on May 18, 2007. Additional rulemaking is anticipated that will ultimately eliminate the low stress piping exemption for all hazardous liquid pipelines.

PHMSA also reorganized and streamlined the applicability section of the hazardous liquid regulations to make them easier to interpret. This streamlining made it clear that PHMSA intends to regulate gathering pipeline segments that cross navigable waters, and that it does not intend to regulate non-low-stress pipelines that are already regulated by the US Coast Guard.

PHMSA ADB-08-04- Installation of Excess Flow Valves into Gas Service Lines [Docket ID PHMSA-RSPA-2004-19854]

PHMSA ADB-08-04- Installation of Excess Flow Valves into Gas Service Lines

[Docket ID PHMSA-RSPA-2004-19854]

PHMSA issued an advisory bulletin to advise gas distribution pipeline operators of a statutory requirement to install excess flow valves in selected gas service lines. The Pipeline Inspection, Protection, Enforcement, and Safety (PIPES) Act of 2006 mandates that PHMSA require operators of natural gas distribution systems to install excess flow valves (EFV) on certain gas service lines. The statute directs that installation of EFVs will be required on single family residence service lines:

  • That are installed or entirely replaced after June 1, 2008;
  • That operate continuously throughout the year at a pressure not less than 10 psi gauge;
  • That are not connected to a gas stream with respect to which the operator has had prior experience with contaminants the presence of which could interfere with the operation of an EFV, and
  • For which an excess flow valve meeting the performance standards of 49 CFR 192.381 is commercially available.

The PIPES Act directs PHMSA to include this requirement in a regulation addressing distribution integrity management programs (DIMP). PHMSA is working on its DIMP regulation and expects a proposed rule to be published shortly. PHMSA intends to analyze public comments and prepare a final rule in an expeditious manner. It is apparent, however, that the final rule cannot be in place before the June 1, 2008, deadline for EFV installation that is in the Act.

PHMSA encourages all gas distribution pipeline operators to take actions to ensure that EFVs are installed on the appropriate service lines that are installed or completely replaced after June 1, 2008.

Proposed Rule: Increasing MAOP for Gas Transmission Pipelines [Docket ID PHMSA-2005-23447]

Proposed Rule: Increasing MAOP for Gas Transmission Pipelines

[Docket ID PHMSA-2005-23447]

The Department of Transportation / Pipeline Hazardous Materials Safety Administration (DOT/PHMSA) proposed to amend the pipeline safety regulations to prescribe safety requirements for the operation of certain gas transmission pipelines at pressures based on higher stress levels. The result would be an increase of maximum allowable operating pressure (MAOP) over that currently allowed in the regulations. Please reference RCP's newsletter article on the proposed rule in the April 2008 edition of DOT Pipeline Compliance News. PHMSA is extending the period for written comments on the proposed rule until May 19, 2008, and will consider late filed comments so far as practicable. Comments should reference Docket ID PHMSA-2005-23447 and may be submitted to the E-Gov Web Site: http://www.regulations.gov. For a complete copy of the proposed rulemaking, contact Jessica Roger.

Advisory Bulletin ADB-08-01 – Direct Sales Pipelines Jurisdiction [Docket No. PHMSA-RSPA-2004-19856]

Advisory Bulletin ADB-08-01 – Direct Sales Pipelines Jurisdiction

[Docket No. PHMSA-RSPA-2004-19856]

Editor’s Note: If you ever wondered why a lot of companies hire us to do jurisdictional determination work, the following article should help make the reasons clear

PHMSA has issued an advisory bulletin stating that the Pipeline Inspection, Protection, Enforcement, and Safety Act of 2006 eliminated the former exception of direct sales natural gas pipelines from the definition of an interstate gas pipeline facility.

The Federal pipeline safety laws (49 U.S.C. 60101 et seq.) define an "interstate gas pipeline facility" as a facility subject to the jurisdiction of the FERC under the Natural Gas Act (15 U.S.C. 717 et seq.). Prior to the passage of the Pipeline Inspection, Protection, Enforcement, and Safety Act of 2006 (PIPES Act) (Pub. L. 109-468), the interstate gas pipeline facility definition contained an exception for a gas pipeline facility transporting gas:

  • from an interstate gas pipeline in a State
  • to a direct sales customer in that State
  • buying gas for its own consumption

Because of this exception, these pipelines were considered to be intrastate pipelines and were regulated on a state-by-state basis. Section 7 of the PIPES Act changed this by eliminating the exception. As a result, direct sales gas transmission pipelines subject to FERC jurisdiction formerly considered to be intrastate pipelines for purposes of the pipeline safety laws are now considered to be interstate pipelines.

As interstate gas pipeline facilities, direct sales pipelines are subject to the applicable Federal pipeline safety regulations and PHMSA is responsible for regulatory oversight and enforcement. In cases where a State has both an annual certification for gas under 49 U.S.C. 60105 and an agreement under 49 U.S.C. 60106(b), inspections of these direct sales pipelines may continue to be conducted by a State pipeline safety agency acting as PHMSA's representative although any enforcement action must be referred to PHMSA.

If the line has a State certification from the State Public Utility Commission (PUC) that such State PUC has regulatory jurisdiction over the rates and service of the line and is exercising it (i.e. the State PUC is exercising economic regulatory jurisdiction, not FERC), that would be grounds for concluding that the line is not subject to FERC jurisdiction and therefore can be regulated as an intrastate pipeline by a State having a certification for gas under 49 U.S.C. 60105.

This change does not affect direct sales pipelines that are intrastate pipelines because they extend from another intrastate line to the consumer.

For a copy of Advisory Bulletin ADB-08-01 contact Jessica Roger.

Has the Gas Gathering definition affected your pipelines?

RCP can conduct a detailed analysis of your gas pipelines to determine end points of production and gathering based upon the recently finalized definition of gas gathering pipelines. The analysis will also determine whether your gathering pipelines are regulated and whether they are classified as Type A or B regulated gas gathering.

Department of Homeland Security Chemical Facility Anti-Terrorism Standards (DHS CFATS) and Impact on Underground Storage of Natural Gas Operations

(Courtesy of the AGA Associate newsletter)

Following extensive discussions and a formal technical session with DHS at which AGA-member company storage operators provided a tutorial of storage operations, member company security professionals detailed storage vulnerability/consequence analyses, and the associations (AGA & INGAA) proposed a more applicable consequence evaluation (C-FER circle and High Consequence Area analysis), DHS has amended the online Top Screen application and analysis to include questions which take into account the differences between underground natural gas storage and underground storage of other types of chemicals (e.g., underground tanks). In the absence of these additional questions, all underground natural gas storage facilities (due to mass quantity, alone) should plan for compliance with the CFATS regulations.

A letter indicating how the facility ranked as a result of the preliminary analysis by the unamended Top Screen tool will be distributed by DHS to the facility operator in June. At that point, the operator will have the option to re-submit facility information (in its entirety) to the amended online Top Screen application. If an operator selects to re-submit, the likelihood significantly increases that the re-evaluation would demonstrate a more favorable analysis for the facility and ideally, would drop the facility from the current CFATS program.

Draft National Pollutant Discharge Elimination System (NPDES) General Permit for Stormwater Discharges From Construction Activities

Federal Register: May 16, 2008 (Vol. 73, No. 96)

EPA is proposing for public comment the issuance of their 2008 National Pollutant Discharge Elimination System general permits for stormwater discharges from new dischargers engaged in large and small construction activities. This draft 2008 CGP contains the same limits and conditions as the Agency's 2003 CGP with the exception of a few minor modifications detailed below. As proposed, EPA is issuing this CGP for a period not to exceed two (2) years. All comments must be postmarked by June 16, 2008. In addition, EPA is also requesting comments on the criteria to be used by the Agency to incorporate, by reference, "qualifying local program requirements" for erosion and sediment control.

Significant changes from the 2003 CGP include clarification that: eligibility for coverage under the 2008 CGP is limited to operators of new and unpermitted ongoing construction projects; operators of ongoing permitted construction projects are not eligible for coverage under the 2008 CGP and removal of eligibility for operators in Tribal Lands in Maine from the list of areas in Appendix B where this permit is effective.

Court Vacates Storm Water Permit Exemption

On May 23, 2008, the U.S. Court of Appeals for the Ninth Circuit vacated a U.S. Environmental Protection Agency rule exempting certain natural gas construction activities (including gas transmission and storage construction projects) from Clean Water Act permitting requirements for storm water discharges. Construction activities that disturb more than 1 acre of soil may be impacted by this ruling, and may need storm water permits even if they were previously exempt.

MMS NTL 2008-G05 Shallow Hazards Program

The U.S. Dept. of the Interior, Minerals Management Service (MMS) issued a Notice to Lessees and Operators and Pipeline Right-of-way Holders (NTL) No. 2008-G05 effective May 1, 2008. This supersedes NTL No. 2007-G01, effective February 15, 2007. It (1) specifies the group intervals for acquiring medium penetration seismic profiler information, (2) discontinues the process of obtaining prior approval if you want to substitute 3-D data and information for high-resolution subbottom profiler or a medium penetration seismic profiler information, (3) clarifies the procedures for submitting shallow hazards reports on CD-ROM’s, (4) amends the format for listing magnetic anomalies and sidescan sonar contacts in shallow hazards reports, (5) clarifies that the onsite provisions for mitigation of shallow hazards apply to lift and jack-up boats, and (6) allows a MODU or other vessel to depart a location without fully raising its legs or mat as long as they are raised sufficiently to ensure no contact with pipelines and other potential hazards.
