Gathering Lines
  • Final Rule Issued
  • April 14, 2006
  • Amendment 192-102
  • Adopts a consensus standard (in part) to
    distinguish onshore gathering lines from other
    gas pipelines and production operations.
  • Consensus Standard
  • API Recommended Practice 80
  • Guidelines for the Definition of Onshore Gas
    Gathering Lines

4
API Recommended Practice 80
  • Defines onshore gas gathering lines through a
    series of definitions, description and diagrams
    intended to represent the varied and complex
    nature of production and gathering in the U.S.

Gathering Lines
  • Regulation based on risk the line poses to the
    public
  • Based on pressure and proximity to people
  • Operator must use API RP 80 to determine if an
    onshore pipeline is an onshore gathering line
    subject to the following limitation

8
Gathering Lines
  • The beginning of gathering may not extend beyond
    the furthermost downstream point in a production
    operation
  • Does not include equipment that can be used in
    either production or transportation (separators
    or dehydrators) unless that equipment is involved
    in the process of production and preparation for
    transportation or delivery of hydrocarbon gas

9
Gathering Lines
  • The endpoint of gathering may not extend beyond
    the first downstream natural gas processing plant
  • If the endpoint of gathering is determined by
    commingling of gas from separate production
    fields, the fields may be no more than 50 miles
    apart
  • The endpoint of gathering may not extend beyond
    the further most downstream compressor used to
    increase gathering line pressure for delivery to
    another pipeline

10
API Recommended Practice 80
  • Production Operation means piping and equipment
    used for production and preparation for
    transportation or delivery of hydrocarbon gas
    and/or liquids and includes the following
    processes
  • (a) Extraction and recovery, lifting,
    stabilization, treatment, separation, production
    processing, storage, and measurement of
    hydrocarbon gas and/or liquids

11
Gathering Lines
  • Two types of gathering lines
  • Type A
  • Type B

12
Jurisdictional Gathering Lines
  • Type A
  • Metallic and gt20 SMYS
  • Nonmetallic and gt125 psig
  • Class 2, 3 and 4 locations

13
Jurisdictional Gathering Lines
  • Type B
  • Metallic and lt20 SMYS
  • Class 3 and 4 locations
  • Also in class 2 locations using 3 different
    methods
  • Class 2 location
  • Area extending 150 feet on each side of
    continuous 1 mile segment of pipeline including
    more than 10 or less than 46 dwellings
  • Area extending 150 feet on each side of
    continuous 1000 feet of pipeline including 5 or
    more dwellings

14
Jurisdictional Gathering Lines
  • Type A
  • All parts of code that apply to transmission
    lines
  • Type B
  • If line is new, replaced, relocated or changed,
    must be designed and tested in compliance with
    code
  • Metallic line Corrosion control requirements
  • Damage Prevention
  • Public Education
  • MAOP
  • Line Markers

15

16
Gathering Seminar
  • November 28, 2006
  • Marietta, Ohio
  • Dewitt Burdeaux
  • Time and location to be determined

17
Minimum Gas Service Standards
18
Minimum Gas Service Standards
  • Nothing has changed from the last rehearing on
    these rules
  • OCC had filed for rehearing and the Commission
    stayed with the original entry
  • The Commission waited until the rehearing
    timeframe had expired before moving forward

19
Minimum Gas Service Standards
  • PUCOs Legal Department has not sent the rules
    over to JCARR to date
  • Working on finalizing forms
  • Once the forms are finalized, the rules will be
    submitted to JCARR to go through their process

20
JCARR
21
JCARR
  • Joint Committee on Agency Rule Review
  • 119.032 of Ohio Revised Code
  • Requires all state agencies to conduct a review
    (every 5 years) of their rules (OAC) and to
    determine whether
  • Continue rules without change
  • Amend their rules
  • Rescind their rules

22
JCARR
  • Section 119.032(c), Revised Code requires
    Commission to determine
  • The rules should be continued, be amended, or be
    rescinded, taking into consideration the purpose,
    the scope, and intent of the statute
  • The rules need amendment or rescission to give
    more flexibility at the local level
  • Rules need amendment or rescission to eliminate
    unnecessary paperwork

23
JCARR
  • Agency proposes changes to rules
  • Submitted to JCARR. JCARR has jurisdiction over
    these rules for 65 days. In the last 30 days,
    JCARR has a meeting where rule is on the agenda.
  • JCARR does not approve the rules, only recommend
    that they go forward or additional changes be
    made.
  • Once JCARR loses its jurisdiction, there is a 10
    day waiting period. Then rules become effective.

24
JCARR
  • Formally, PUCO was allowed to incorporate by
    reference all federal pipeline safety regulations
    (Part 192).
  • A few years ago, there were a few court decisions
    that limited the PUCOs ability to adopt these
    rules by incorporation.

25
JCARR
  • In addition, each time the Federal Regulations
    (Part 192) are changed
  • PUCO must do a rulemaking to adopt those changes
    and go through the JCARR process
  • PUCO plans on doing this on a semi-annual to
    annual basis
  • Unless there is a major rulemaking that we need
    to adopt sooner

26
Public Awareness
  • API 1162

27
Public Awareness
  • Final Rule published May 19, 2005 (June 16, 2005)
  • Incorporates by reference the guidelines of the
    American Petroleum Institute (API) Recommended
    Practice 1162 (RP 1162)
  • Operators must develop and implement public
    awareness programs

28
Public Awareness
  • Pipeline Safety Improvement Act of 2002
  • Requires operators to evaluate and, where needed,
    improve their pipeline safety awareness programs

29
API 1162
  • Industry consensus standard provides guidance and
    recommendations, including
  • Intended audiences
  • The kinds of information to be communicated
  • Frequencies and methodologies for communicating
    the information
  • Evaluation of the programs for effectiveness

30
Public Awareness
  • All pipeline system operators must follow the
    baseline, and where appropriate, the supplemental
    requirements of API 1162
  • All operators had to comply with this by June 20,
    2006

31
Public Awareness
  • Under the regulations, operators of gas and
    hazardous liquid pipeline facilities must carry
    out continuing programs to educate the public on
     
  • the use of a One-Call notification system prior
    to excavation, and other damage prevention
    activities
  • the possible hazards associated with unintended
    releases from the pipeline facility
  • the physical indications that such a release may
    have occurred
  • what steps should be taken for public safety in
    the event of a pipeline release and
  • how to report such an event.

32
Public Awareness
  • Operators must include in their programs
    activities to advise affected municipalities,
    school districts, businesses, and residents of
    pipeline locations. Of significance is the
    requirement that operators must review their
    programs for effectiveness and enhance the
    programs as necessary.

33
Public Awareness
  • On June 16, 2006, PHMSA issued an Advisory
    Bulletin to tell certain pipeline operators how
    to submit their written public awareness programs
    for review.
  • The 2002 PSIA requires pipeline operators to
    submit these programs for review.
  • PHMSA has implemented a Clearinghouse for
    reviewing operator submissions.

34
Public Awareness OGA Plan
  • Ohio Gas Association members
  • Collaborative effort
  • Hired Devaney and Associates
  • Developed a plan for all Ohio Gas Association
    members
  • Plan has been reviewed by members of the Pipeline
    and Hazardous Materials Safety Association (PHMSA)

35
Public Awareness OGA Plan
  • No issues were identified by PHMSA Central Region
  • No issues have been identified by PUCO
  • PUCO was involved in process from the beginning
  • Thorough plan, collaborative effort, strong
    message
  • OGA Collaborative Plan has been discussed across
    NAPSR and PHMSA as a model plan

36
Public Awareness OGA Plan
  • No other association has gone as far as Ohio Gas
    Association has with all aspects of Public
    Awareness
  • As long as member companies customize template,
    they should be in compliance with requirement

37
Public Awareness OGA Plan
  • Ohio has agreed to participate in the PHMSA
    centralized review process
  • Team made up of PHMSA staff, state pipeline
    safety programs, PHMSA contractor
  • If deviations from baseline elements are found,
    the review team will refer the issues to state
    pipeline safety agency (PUCO)

38
Public Awareness
  • During the first half of the public awareness
    program submittal period, PHMSA received 276
    programs covering 375 operators. This represents
    about 14 of the operators expected to submit
    programs.

39
Public Awareness Plan
  • File your plan ASAP
  • Deadline October 7
  • No penalty for filing early

40
Public Awareness
  • All states are participating except for
  • Connecticut
  • DC
  • Illinois
  • Maryland
  • Montana
  • South Dakota
  • Virginia
  • Wyoming

Ohio Revised Code
  • 4901.16. Penalty for divulging information.Except
    in his report to the public utilities commission
    or when called on to testify in any court or
    proceeding of the public utilities commission, no
    employee or agent referred to in section 4905.13
    of the Revised Code shall divulge any information
    acquired by him in respect to the transaction,
    property, or business of any public utility,
    while acting or claiming to act as such employee
    or agent. Whoever violates this section shall be
    disqualified from acting as agent, or acting in
    any other capacity under the appointment or
    employment of the commission.   

47
Final Report
  • Will be docketed
  • Everyone on service list should be served by our
    docketing department
  • I will notify Ohio Gas Association

48
Updates to OQ
49
OQ
  • PHMSA is considering three changes to regulations
  • Training
  • Reevaluation intervals
  • New construction

50
OQ
  • Training
  • an OQ program would have to include training in
    particular circumstances. These circumstances
    are
  • an individual has never performed an assigned
    covered task
  • there has been substantial change to a covered
    task
  • ensure training in damage prevention for
    individuals performing excavation for the
    operator

51
OQ
  • Reevaluation Intervals
  • Considering requiring an operator to set maximum
    intervals for reevaluation for every task
  • Intervals would not exceed five years

52
OQ
  • New Construction
  • require an operator to have a process to verify
    the integrity of new construction
  • using accepted quality control practices during
    construction
  • new construction tasks in OQ programs
  • using integrity verification methods
  • pressure testing
  • nondestructive testing

53
OQ
  • Non-regulatory
  • Other clarifications, possibly by advisory
    bulletin, would enhance an operators
    understanding of the requirements
  • Emergency response
  • Abnormal operating conditions

54
Advisory Bulletin on Excavation Activities
  • January 17, 2006
  • PHMSA issued advisory bulletin
  • Reinforcing the need for safe excavation
    practices
  • Recommends that pipeline operators integrate the
    OQ regulations into
  • Marking
  • Trenching
  • Backfilling
  • Reminds operators that excavation is considered a
    covered task under the OQ regulations
  • Requires that pipeline operators and contractors
    be qualified to perform pipeline excavation
    activities

55
NAPSR Issues
56
NAPSR
  • NASPR Administrative Manager
  • Pipeline Safety Law Reauthorization
  • Distribution Integrity Management
  • Future Issues

57
NAPSR
  • Administrative Manager
  • Funding provided by PHMSA through a grant
  • NAPSR has drafted a job description, employment
    contract and advertised for the position
  • Applications were due July 1, 2006
  • Final decision to be made by November 1, 2006

58
NAPSR
  • Pipeline Safety Reauthorization
  • Remove the 7 year reassessment interval for
    integrity management out of statutory language.
  • Civil enforcement authority of damage prevention
    for the states.
  • Grants for research and development to improve
    damage prevention such as research on locating
    technology and the one call communication
    process.
  • Locating and siting authority for pipelines.

59
NAPSR
  • Pipeline Safety Reauthorization
  • Permit streamlining
  • Some level of security authority
  • Limited safety requirements for small LP/Master
    Meter operators
  • Ability to charge fee for the review of LNG
    facility designs
  • Providing clarity on direct sales lateral issue

60
NAPSR
  • Pipeline Safety Reauthorization
  • Administrations Proposed Bill Language Forwarded
    to Congress in early June
  • Introduced As HR 5678
  • House Transportation And Infrastructure Committee
    HR 5782

61
NAPSR
  • Distribution Integrity Management
  • NAPSR participated in DIMP committees
  • NAPSR working on teams developing guidance
    material with GPTC

62
NAPSR Future Issues
  • Inside Meters
  • Illinois fined an operator for not inspecting
    inside meters
  • Has been an issue in Ohio
  • Look for enforcement to increase in future

63
811
  • The Federal Communications Commission (FCC)
    released an order on March 14, 2005
  • Designated the 811 dialing code as a nationwide
    number to be used by state one-call notification
    systems for providing advanced notice of
    excavation activities to underground facility
  • Operators implement the Pipeline Safety Act which
    provides for the establishment of a nationwide
    toll-free abbreviated dialing arrangement to be
    used by state one-call notification systems

64
811
  • Commission opened docket (05-1306-AU-COI) to
    address any issues that may exist for one-call
    centers in Ohio on October 25, 2005
  • November 4, 2005, the Commission issued an entry
    by which it invited interested parties to file
    comments and/or reply comments addressing any
    technical, operational, cost, or compensation
    issues pertaining to 811 implementation, along
    with recommendations regarding what, if any,
    steps the Commission should take in order to
    ensure that they are resolved in a timely manner
  • Whether and how it may be possible for both Ohio
    one-call centers to receive 811 calls from the
    same area

65
811
  • Nearly all of the initial and reply comments
    expressed support for the idea that the
    Commission should designate one of the existing
    Ohio one-call centers, namely the Ohio Utilities
    Protection Service (OUPS), as the sole 811
    one-call system provider in Ohio
  • Nearly all of the local exchange telephone
    companies who filed comments expressed the view
    that it is not feasible to have two separate
    one-call centers make simultaneous use of the
    811dialing code in the same area

66
811
  • May 4, 2006, the Commission held public workshop
    on this issue and collected information.
  • The Ohio Commission is in the process of working
    with the industry in determining the best method
    for the implementation of 8-1-1.  Although no
    carrier has yet to file a tariff proposal or cost
    study it is likely that all carriers will incur
    some level of cost in implementing 8-1-1.  As to
    how the cost may be recovered and by whom, will
    be determined by the Ohio Commission later this
    year.

Distribution Integrity Management Regulations
68
Timeline
  • Inspector Generals Report - July 2004
  • American Gas Foundation (AGF) Report - December
    2004
  • Allegro Report (For OPS/PHMSA) - 2004
  • DIMP Committee Report - December 2005
  • GPTC/DIMP Standard Work - 2006
  • NPRM - Fall of 2006
  • Public Meeting - Early 2007

69
Inspector Generals Report
  • July 20, 2004 report to US House of Rep.
  • Gas Distribution Lines make up 85 of the 2.1
    million miles of natural gas pipelines in the
    United States.
  • Natural gas distribution pipelines over the last
    10 years have experienced over 4 times the number
    of fatalities and 3.5 times the number of
    injuries when compared to hazardous liquid and
    transmission pipelines.

70
Inspector Generals Report
  • Distribution
  • 174 fatalities
  • 662 injuries
  • Transmission and Hazardous Liquids
  • 43 fatalities
  • 178 injuries

71
Inspector Generals Strategy
  • Three Elements of DOTs IG Plan
  • Understanding the infrastructure
  • Identifying and characterizing the threats
  • Determining how best to manage the known risks
    (prevention and mitigation issues)

72
American Gas Foundation Report
  • Looked at three major areas
  • Natural Gas Distribution Industry Safety
    Performance
  • Current Regulations and Industry Practices that
    address threats to the natural gas distribution
    infrastructure
  • Differences between Gas Transmission and Gas
    Distribution Infrastructure

73
American Gas Foundation Report- Findings
  • Key differences noted between distribution and
    transmission infrastructure
  • Type of infrastructure
  • System operating pressures
  • Materials of construction
  • Typical failure mechanisms
  • Inspection methods
  • Class locations
  • Connection to customers

74
American Gas Foundation Report- Findings
  • Visual inspection of piping is more prevalent in
    distribution than transmission systems
  • Many operators actively participate in damage
    prevention organizations
  • Some one call programs allow exemptions from one
    call membership and not all include
    fines/penalties for offenders

75
American Gas Foundation Report- Findings
  • Current pipeline regulations address threats to
    distribution infrastructure
  • Operators employ prevention and mitigation
    practices in excess of those required by law
  • Downward trend in incident fatalities and
    injuries (1990-2002)
  • Major cause of incidents is outside force damage
    third party damage

76
Allegro Report
  • Completed in 2004 for OPS/PHMSA
  • Evaluated five years of incident data (1999-2003)
  • Attempted to reclassify them into the new cause
    categories listed in the current incident
    reporting forms
  • 67 incidents were outside force damage
  • 38 excavation and mechanical damage
  • 11 vehicle damage (contributed to 25 of fatal
    incidents)

77
OPS/PHMSA Creates DIMP Committee
  • Building on AGF Report, DIGIT Committee, State
    and Industry Initiatives
  • Involve all stakeholders
  • Assure flexibility to the maximum extent
    practicable
  • Identify strategies to implement selected
    integrity management options

78
Team Structure
  • Executive Steering Team
  • Coordinating Team
  • Task Teams
  • Strategic Options
  • Risk Control
  • Data
  • Outside Force

79
  • Strategic Options - Identify options to implement
    for distribution system safety
  • Risk Control - Evaluate the effectiveness and
    applicability of the current regulations as well
    a reviewing current risk control practices in
    government and industry
  • Data - Assemble existing information to identify
    the type, significance, and trends for threats
    affecting distribution pipelines
  • Outside Force - Review Common Ground Alliance
    database and related information to identify
    practices being used to prevent outside force
    damage and the extent of the applications

80
Implementation Options to be Considered
  • Structured Nation-Wide Education Program
  • National/local advertising campaign similar
    to call-before you-dig
  • Model State Legislation
  • Prepare draft language that could be
    incorporated by States into legislation
    addressing distribution pipeline safety issues.

81
Implementation Options to be Considered
  • National Consensus Standard or Guidelines
  • National Consensus Standard or other guidance
    document detailing specific practices for
    improving distribution pipeline safety under
    different circumstances.
  • Guidance Document for Adoption by States
  • Similar to above except made mandatory. States
    could adopt in whole or in part based on local
    needs.

82
Implementation Options to be Considered
  • Simple Flexible Federal Regulation
  • Regulation requiring that each operator have an
    integrity plan that reflects (a) knowledge of
    infrastructure, (b) consideration of applicable
    threats, (c) activities to reduce risk, and (d)
    process for monitoring performance.
  • Prescriptive Federal Regulation
  • Regulation similar to the integrity management
    rule for gas transmission pipelines

83
Implementation Options to be Considered
  • Development of Innovative Safety Technology
  • Support research and development of techniques
    to assess the integrity of small-diameter,
    networked pipeline systems of varying materials.

84
DIMP Report
  • Finalized in December 2005
  • The DIMP report recommends the following
  • A high-level flexible federal regulation
  • Implementation guidance
  • Nationwide education program for implementation
    of 811 for One Call programs
  • Continued research and development

85
DIMP Report
  • Differences between gas distribution and
    transmission systems make it impractical to
    establish prescriptive requirements that would be
    appropriate in all cases
  • The report recommended that an operators
    distribution integrity management program consist
    of seven key elements

86
7 Key Elements of a Distribution Integrity Plan
  • Develop and implement a written integrity
    management plan
  • Know its infrastructure
  • Identify threats
  • Assess and prioritize risks
  • Identify and implement mitigation measures
  • Measure performance, monitor results, and
    evaluate the effectiveness of it programs
  • Periodically report a limited set of performance
    measure to its regulator

87
Excavation Damage
  • Most significant single threat to distribution
    system integrity
  • Recommended 9 key elements for an effective
    damage prevention program
  • Not all states have this type of program
  • Federal legislation needed to support development
    by all states
  • Single greatest opportunity to distribution
    safety improvements

88
9 Elements to an Effective Damage Prevention Plan
  • Enhanced communication between operators and
    excavators
  • Fostering support and partnership of all
    stakeholders in all phases
  • Operators use of performance measures for
    persons performing locating of pipelines and
    pipeline construction
  • Partnership in employee training

89
9 Elements to an Effective Damage Prevention Plan
(contd)
  • Partnership in public education
  • Enforcement agencies role as partner and
    facilitator to help resolve issues
  • Fair and consistent enforcement of the law
  • Use of technology to improve all parts of the
    process
  • Analysis of data to continually evaluate/improve
    program effectiveness

90
Other Notables
  • EFVs should not be federally mandated
  • The management of gas leaks is fundamental to
    successful management of distribution risk and a
    vital risk control practice
  • Distribution pipeline systems are relatively safe
  • Incidents occur but have been reduced
  • There is room for improvement

91
GPTC/DIMP- Implementation Guidance
  • In order to address DIMP recommendations, PHMSA
    asked GPTC to begin writing guidance material
  • GPTC combined with stakeholder groups represented
    in the DIMP phase one group to begin writing
    guidance
  • Meetings held in April, June, and August 2006
  • Five subgroups working to address the seven key
    elements

92
GPTC/DIMP- Implementation Guidance
  • Final draft to be given to GPTC Members during
    their November meeting
  • Hope to have in the next edition of the GPTC
    manual that will be available the middle of 2007

93
NPRM/Public Meetings
  • NPRM is expected sometime in October
  • PHMSA is planning a public meeting sometime
    during the first of the year
  • Final rule planned by the end of 2007
