AGA Perspectives on Current
Pipeline Safety Regulations
The American Gas Association
• The American Gas Association , founded in 1918, represents
more than 200 local energy companies that deliver clean
natural gas to more than 68 million Americans nationwide.
• Members deliver 94% of the natural gas in the US

Key DOT Pipeline Safety Activities
• 9 Rulemakings In Progress
• 42 Legislative Mandates
• Recommendations from NTSB, OIG,
GAO
• Advisory Bulletins
• Numerous other initiatives to improve
pipeline safety
• SMS
• Data Analysis Improvements
• Inspection Program – Inspection Integration

Safety of Gas Transmission &
Gathering Lines Rule
• Expected to include:
• IVP: Expansion of IM + Testing
• NTSB Recommendations
• Eliminate Grandfather Clause
• Pressure test lines to 1.25 MAOP +
spike test
• Legislation
• Confirm material strength of
previously untested lines
•
Located in HCAs & operating above 30%
SMYS
• Repair criteria for both HCA and nonHCA areas
• Gas gathering lines & Other items
• Assessment methods, corrosion control,
problematic or “legacy” pipe, etc.
Rule Status
• ANPRM published
August 25, 2011
• NPRM has moved
past PHMSA
• Still within DOT
• Labeled a
Significant rule

AGA Position on Proposed Integrity Verification Process
Complexity
• IVP Combines MAOP with TIMP expansion
MAOP
Foundation
• Validation is a one time activity
• IVP nullifies valid MAOPs based on historical PHMSA regulations and ASME
B31.8
• Lacking complete MTRs = coupon sampling program to establish material
prosperities
Post Construction
Pressure Test
MCA
• Records of historic pressure tests that currently meet code requirements
should be acceptable
• Introduces MCA Concept
• Class 2, 3 & 4 non-HCA + Class 1 with 1 home in PIR
New
Definitions
• High Stress Line is defined as ≥ 20% SMYS
• Legacy Pipe: No Common Definition
• Susceptible Seam Type: No Common Definition
• Engineering Critical Assessment (ECA): Not currently defined or understood
Spike Test
• Should be situational and operational decision

National Pipeline Mapping System
• AGA Supports a modernization of the NPMS
• Dramatic increase in quantity of data requested
• Concerns on security of pipeline infrastructure
• Industry believes this request should be
formalized in Rule Making not Information
Collection
• Proposal is significant burden on many operators
• PHMSA Estimated Burden = 420,516 hours
• 347 hours / respondent
• Very high estimate for PHMSA
• & still too low
Examples of Data
Requests
New Data Requested
Includes
• Narrow positional
accuracy

• 5 Feet
• Pipeline material and
manufacturing details
• Location details on
facilities
