ILLINOIS COMMERCE
COMMISSION
Darin Burk
Manager – Pipeline Safety
Distribution Integrity Management
2



Proposed Rule published in the Federal Register on
June 25, 2008
Numerous comments were received by the Pipeline
and Hazardous Materials Safety Administration
(“PHMSA”)
Final Rule expected in September of 2009
Why is PHMSA Proposing DIMP?
3


Additional prescriptive requirements would bee too
burdensome on the pipeline industry.
More effective to allow operators to analyze their
system, identify weaknesses that could result in high
consequence incidents and address those
weaknesses.
Program Implementation
4


Distribution system operators will have 18 months
from the published date of the final rule to develop
and implement a Distribution Integrity Management
Program.
The DIMP will address 7 basic elements.
Element 1: Knowledge
5






Identify the characteristics of the system and the
environmental factors necessary to assess applicable
threats and risks to the system.
Understand the design and operation.
Identify the additional information needed
Determine how to obtain additional information
Have a process to refine plan
Record data for newly installed facilities
Element 2: Identify Threats
6

Threat Categories
 Corrosion
 Natural
Forces
 Excavation Damage
 Other Outside Force
 Material or Weld Failure
 Equipment Malfunction
 Inappropriate Operation
 Other Concerns
Element 3: Evaluate and Prioritize
Risk
7




Determine the relative probability of each threat
Determine likelihood of failure
Determine potential consequences
System may be subdivide the system into regions of
similar characteristics and consistent risk
Element 4: Identify and Implement
Measures to Address Risks
8




Effective leak management program
Enhanced damage prevention
Assuring individual performance (Training &
Operator Qualification)
Quality assessment
Element 5: Measure Performance, Monitor
Results & Evaluate Effectiveness
9






Number of hazardous leaks either eliminated or
repaired
Number of excavation damages
Number of excavation tickets
Number of EFV’s installed
Total number of leaks eliminated or repaired
Additional measures
Element 6: Periodic Evaluation
10




Continually re-evaluate threats and risks on the
entire system
Evaluate the effectiveness of the program for
assuring individual performance to reduce the risk
of human error
Determine appropriate period for complete
program re-evaluation based on complexity and
changes in factors
Maximum of 5 year re-evaluation interval
Element 7: Reporting Results
11



Must report plastic pipe material failures including:
fittings, couplings, valves, and mechanical joints
Must be reported no later than 90 days after
failure
Include: location, pipe size, material type, nature of
failure, pipe manufacturer, lot number, date of
manufacture and other information found in
markings on failed pipe
Excess Flow Valves
12



Required on all single family residences
New installations and replacements
Not require if:
 System
operates below 10 psig
 Operator has knowledge of contaminates
 Could interfere with necessary operation and
maintenance activities
 If EFV meeting performance standards is not available
to operator
Deviation from Required Inspections
13


Operators will be allowed to propose inspection
intervals that are outside the current required time
limits
The ICC will review the request and determine if the
operator will be allowed to extend inspection
intervals
Does This Rule Apply To Master Meter
Operators?
14


Yes.
Master Meter operators will be required to meet 5
elements:
 Infrastructure
Knowledge
 Identify Threats
 Identify & Implement Measures to Mitigate Risks
 Measure Performance, Monitor Results, Evaluate
Effectiveness
 Periodic Evaluation and Improvement
