What is NFPA 59A

• Because 59A is a technically balanced, open
  consensus standard representing many disciplines
  associated with LNG and the public,
• The focus of the Technical Committee is to keep
  this standard in the forefront of its field by
• Maximizing reliability, which represents safety,
• Improving design / liquid containment
• These changes, together with better technology,
  will result in safer plants and better siting
  requirements.

NFPA 59A is a Living Code

• Whats on the 59A horizon.
• Risk based analysis a task group is working
  developing this concept.
• It is based on philosophy developed for
  Integrity Management Plan for pipelines,
  recognizing this is a LNG Facility, not a
  49CFR192 pipeline.

Keeping NFPA 59A Current

• Thermal Radiation Now Thermal Radiant Energy
• A funded task group is reviewing radiant heat
  levels that have been cited in literature that
  has been the basis for all plant design.

Keeping NFPA 59A Current

• Proposals and Comments represent two separate
  opportunities for ALL to update / change NFPA
  59A.
• Public Proposal Comment Period Closes for the
  next edition of NFPA 59A on November 22, 2006.
• Public Comment Period on these Proposals Closes
  on August 31, 2007

What is Coming

• Vapor Dispersion
• A funded research group has been formed to
  independently review existing vapor dispersion
  models.
• Its work product will guide 49CFR 193 and NFPA
  59A

How to Change NFPA 59A

• Proposed Changes Must Be Approved By Committee
  and Then Submitted To NFPA in Open Meeting Where
  Public Can Verbally Address Proposed Document
• The technical committee has met to review all
  comments to proposed specification.
• This review has to be balloted to committee.
• Last minute revisions can be made to incorporate
  public comments based on committee review and
  approval.
• NFPA has modified its public comments at the
  national meetings by introducing the NITMAM
• Notice Intention To Make A Motion
