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 Implementation4

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: Knowledge5

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 Risks8

Effective leak management program Enhanced damage prevention Assuring individual performance

(Training & Operator Qualification) Quality assessment

Element 5: Measure Performance, Monitor Results & Evaluate Effectiveness9

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 Valves12

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
