AGA Perspectives on DA

AGA Perspectives on DA

• OPS Direct Assessment Workshop
• November 4, 2003
• Houston, TX
• Paul Gustilo
• American Gas Association
• pgustilo_at_aga.org
• 202-824-7335

Presentation Outline

• General Outlook
• DA Challenges
• Review of Legislative/Regulatory Deadlines
• Use of ECDA
• Research and Demonstration Efforts
• Confirmatory Direct Assessment (CDA) as a
  re-assessment method
• Path forward

3
General Outlook on DA

• Majority of LDCs will rely on DA (primarily ECDA)
  to meet legislative and regulatory mandates
• Mandates are forcing a steep learning curve on
  the application of DA
• Many challenges - industry is committed to
  working with stakeholders on meeting challenges

4
Some DA Challenges

• Refining applicability and limitations of DA
• Gaining confidence of regulators on applicability
  and limitations of DA
• Meeting demand for DA services (particularly
  ECDA)
• Coordination among stakeholders (govt industry)

5
Some DA Challenges

• Development and maintenance of DA standards
• Maintaining flexibility on applying the DA
  standards, i.e. variations in testing protocols

6
Review of Legislation/Regulation Key Dates
(assuming a Dec. 17, 2003 FR)
Re-assessment every 7 years
TPSSC/OPS meeting discussion (transcripts)
indicate support for providing DA the same
schedule as ILI and testing. NPRM indicates DA is
on a shorter schedule.

ECDA Users

• Based on OPS Cost Benefit Report
• Potentially 35 pipeline companies (interstate)
• Potentially 240 LDCs and intrastate pipeline
  operators
• Potential application of ECDA for baseline
  assessment 12,500 miles

Possible Outlook on use of ECDA(Potentially 275
Operators by 2012)

DA Research/Demonstration

• PRCI/GTI ECDA and ICDA Efforts, 2000-2002,
  2003-2004 (OPS supporting some of these projects)
• Keyspan Energy ECDA projects
• PGE ECDA projects
• Northeast Gas Association (NGA) ECDA Effort,
  2001-2002 (Phase I)
• NGA ECDA and ICDA efforts, 2003-2004

11
DA Research/Demonstration, Cont.

• GTI/AGA LDC ECDA Effort (Phase I), 2002-2003
• GTI/AGA LDC ECDA (Phase II), ICDA (Phase III)
  both projected for 2004

12
GTI/AGA LDC ECDA Research/Demonstration

• 30 LDCs participating
• 6 Field Demonstrations (IL, MI, MS, PA, TX, OK)
• Regulators from OPS and state representatives
  from CA, CT, IL, MI, MS, NY, PA, TX, and VT have
  observed field work
• Detailed 50 page protocol developed
• Development of Yellow Pages of DA related
  service providers ( 100 companies listed)

Dependent Threats)
14
Path Forward

• Continue research and demonstration (ECDA, ICDA,
  SCC DA)
• Provide opportunities for regulators to observe
  DA process (begin to end)
• Refine standards based on lessons learned on use
  of DA
• Provide opportunities for service providers and
  operators to communicate
• Coordinate/communicate DA activities among
  stakeholders (regulators, researchers, operators,
  service providers, etc.)
