What is Areas of “Active Corrosion”? Definition in the present Columbia’s Gas of

Ohio/Kentucky Gas Standards – 653-8:

T he Columbia gas standards refer Areas of “Active Corrosion” as the

following –

"Active Corrosion" means continuing corrosion which, unless controlled, could result in a condition that is detrimental to public safety. "Active Corrosion" exists only when the following two conditions have been met:

a) The severity and rate of corrosion is significant; and b) In the judgment of the operator, the physical location of the

corroding facility could reasonably create a condition detrimental to public safety.

To define the Criteria of “Active Corrosion” Areas - The safety concern in the wording states detrimental to public safety. We need to observe the two conditions to develop the criteria.

The criteria for classifying Areas of “Active Corrosion”

- The pipeline must show signs of corrosion and has no Cathodic Protection applied

- Severity & rate of Corrosion is significant

- With the severity of corrosion and the location of the pipeline could cause an unsafe situation for the public

def– Significant Sufficient corrosion based on

historical data of repeated localized or generalized corrosion in a general area.

Sufficient corrosion based on the severity, “Generalized Corrosion”.

Best practice – at least review historical

Chapter


What tools to use?We look at the Columbia’s Gas Standards to determine the tools suggested for use, per 653-8.

“Each operating location must establish a program for continual review and evaluation of corrosion indicators to determine if they relate to an "Active Corrosion" area. A corrosion indicator may be any one of the following:”

a) open leak order,b) repair corrosion leak,c) visual observation of pipeline indicating deep pits,d) significant corrosion,e) any anodic corrosion determined by electrical survey; orf) WMS job order type CORR

Corrosion Indicators, What are they and how are they used to determine “Active Corrosion Areas?Each indicator shall be a group effort in determining Suspected and/or “Active

Corrosion” Areas.

1. Open Leaks

The process will require the operation centers to determine these locations of Suspected Areas and/or Areas of “Active Corrosion”.

Communication and Training with Leakage department is required for the personnel to have the complete understanding of sites that meets the criteria or definition.

Leakage department will be require reviewing each DPI created for any candidates of Active Corrosion based on the definition, and therefore communicates to the operational center reporting FOL.

If the FOL is in agreement to the initial assessment, then the segment shall be documented onto the Suspected Area of “Active Corrosion” log book as the first step.

Chapter

2Chapter


*Note: Leakage department will be provided an updated training on Suspected and “Active Corrosion” Areas criteria and definition.

2. Repair Corrosion Leaks

The process will require the operation centers to determine the locations of Suspected Areas and/or Areas of “Active Corrosion”

All executed DPI’s shall be review by the designated operation’s center FOL to determine any areas of candidates for Areas of “Active Corrosion” based on the definition

Any DPI’s field involvement due to possible generalized corrosion with the operation’s center FOL shall be evaluated for a possible candidates for Areas of “Active Corrosion”

All candidates of Areas of “Active Corrosion”, shall be placed onto the Suspected Areas of “Active Corrosion” log as a first step

3. Visual observation of pipe indicating deep pits – The process will require the operation centers and joint effort of the

Corrosion department to determine the locations of Suspected Areas and/or Areas of “Active Corrosion”

Any excavation and pipe line exposure with indications of sever corrosion due to deep pits, should involve the Operation’s Center reporting FOL and the area’s Corrosion Technician for proper measurements and classification

Most systems with a visual observation of deep pits that have been determine of a Generalized corrosion classification shall be evaluated for Areas of “Active Corrosion”

If areas meets the definition of “Active Corrosion”, then the section shall be placed on the “Suspected Active Corrosion” log book as a first step

4. Significant Corrosion – The process shall require the joint effort of the operation centers

and the Corrosion department to review these indicators.

Corrosion Department

1) Shall compile any “Corr” orders, such as leaks on coated pipe, Leaks on CP, Investigate DPI’s or Generalized corrosion and etc., and review for any possible Areas of “Active Corrosion”

2) Corrosion Technicians shall list any areas that meet the criteria onto the Suspected “Active Corrosion” Areas log book

3) Form – C 1282-15, exhibit B on 653-8

Operational Department

1) Designated FOL, shall compile any areas that have a history of significant corrosion that may not be classified as Generalized Corrosion, such as several DPI’s with Localized Corrosion in a specific location for candidates of Areas of “Active Corrosion”,

i. Any Areas with a repeat of Class 1 or 2+

ii. Any Areas with more than three main line corrosion leaks (localize) recorded for the last 9 years

iii. Any Areas with historical Generalized Corrosion, with pending or completed DPI’s in the same general area

2. If by historical review of data appear to meet the criteria of Areas of “Active Corrosion”, then the segments shall be placed in “Suspected Area of “Active Corrosion Log” as the first step

3. Form – C 1282-15, exhibit B on 653-8

*Note: Rolling measurement used for an area of 500 feet in either direction to define the investigative term “Area”

5. Any anodic corrosion condition determined by electrical survey –

i. Electrical Survey shall be conducted by the Corrosion Department

ii. Based on anomaly identification for mitigation of bare or coated pipelines, may be requested by the Engineering department

5


iii. Corrosion Department shall evaluate the data and determine anodic areas

iv. Any anodic areas will be evaluated based on the criteria of “Active Corrosion” Areas based on the survey results in comparison to the location that may be detrimental to public safety

v. Corrosion Technician shall collect data and provide data: place information onto the proper form

vi. Form – C 1282-15, exhibit B 653-8

6. WMS job order with job type “CORR”i. All WMS generated orders with the job type “CORR” that are

associated with a completed DPI order, shall be evaluated for any Suspected Areas of Active Corrosion by the responsible Corrosion Technician

Generalized Corrosion

Leaks on CP system

Cleared DPI “investigate” & etc.

ii. The Corrosion Technician shall evaluate the information and data that is available or any information obtain in the field to determine, if any areas meets the criteria of “Active Corrosion”

iii. Any Candidates shall be placed on the Suspected Area of “Active Corrosion” Log as the first step

Communication Steps – Only individuals to enter information or data into the Suspected Areas of “Active Corrosion” log sheet shall be the area’s Corrosion Technician and the Designated FOL

Field leaders that have performed any of the Corrosion Indicators listed as above and have determined a possible Suspect of “Active Corrosion’ shall notify the Designated FOL for data entry by communication of email. The Designated FOL shall enter the information in the book onto the form – C 1282-15, exhibit B 653-8.

The Corrosion Technician shall communicate to the Designated FOL and Corrosion FLL of any entry onto the Areas of Suspected “Active Corrosion” log sheet by email.

It will be the Corrosion Technician responsibility for the proper data entry and data collection to support the entry for the Semi-Annual meeting.

The Designated FOL shall be responsible of over-seeing the entire log book and process, such as updates, filing of documents, execution of orders and proper data field entry on to the correct forms.

Commitment to SafetyAt all time during the investigation of prior of the investigation, departmental leadership shall have an obligation of responsibility to the public safety.

At any time the pipeline appears to be un-safe of the situation appears un-stable, then the operations should act accordingly of a correct course of action “promptly” .

The indicators of Areas of “Active Corrosion” process does not postpone any necessary actions to be taken, if needed “promptly”.

This shall be taken into consideration for all cases.

Operation’s leadership staff will be held accountable for this assessment.

How do we determine “Active Corrosion”?The first step, determine areas of Suspected Areas of “Active Corrosion” for investigation by the Corrosion indicators.

Semi-Annual meeting shall be conducted for review of data collection at the time of segment entry onto the Suspected Areas of “Active Corrosion log sheet”.

To determine areas of “Active Corrosion,” consideration must be given to the previous discussed criteria with review of the all data collected, such as -

Historical data on DPI’s Open and Completed “CORR” orders Any Open DPI’s

All data collected shall be reviewed for any areas of corrosion, unless controlled could result in a condition that is detrimental to public safety.

A group consensus of the SME (Subject Matter Experts) shall review the information for final decision.

When review of the corrosion indicators identifies a suspected area, an fact, exist. The location of the facility, type of cover, leakage repair records, leakage survey records, corrosion survey records, etc. should be considered in determining if continuing corrosion which, unless controlled, could result in a condition that is detrimental to public safety.

Form C 1282-15, "Investigation of Suspected Areas of 'Active Corrosion,'" Exhibit B, shallbe used to document the review.

If the investigation determines that a pipeline section is not in an area of "Active Corrosion,"a recommendation may be made to:

a. take no additional action until a new corrosion indicator is identified;b. inspect for leakage more frequently;c. repair the facility;d. any combination of b and c.

NOTE: The repair of a pipeline due to existing leakage and/or past leakagehistory does not necessarily indicate that the pipeline is in an "Active Corrosion” area.

If the investigation determines that an area of "Active Corrosion" does exist, the locationand date of determination shall be recorded on Form C 1282-16, "Area of 'Active Corrosion'Log," Exhibit C.

Form C 1282-16 shall be completed by the operating location, maintained by calendar year, and retained in accordance with the Company’s document retention schedule. If no areas of“Active Corrosion” is identified; the log shall be completed indicating no “ActiveCorrosion” for the operating area for the calendar year.

4Corrosion Indicator Data Sheet - Annual SummaryAny Corrosion Indicator Data Sheet Annual Summary Sheets, Form C 1282-14, Exhibit A of the 653-8 of the Columbia’s Gas Standards, can be used for reviewing historical information to help in the investigation but is not mandatory.

This process should be set up through the operations in communication with the Leakage Inspectors.

WMS Data Base Information

WMS generated or created orders, such as DPI’s, Corrosion job orders known as “CORR” job types, and Main exposures will help the local operational centers and Corrosion department to pull adhoc reports if needed, for general viewing and researching.

Any Adhoc reports


Global Information System can be used as an important tool for data collection and investigative work.

A simple use of collection of data entry information onto an inventory mapping system may be of some use to investigate corrosion indicators.

Color coded patterns placed on maps indicating leakage history

Suspected “Active Corrosion” Areas – DocumentationForm C 1282-15 – needs to evaluated, and updated yearly per 653-8

Columbia’s practice will require review semi-annually.

A new form shall be placed in the log book to represent each year.

Sections of pipeline shall stay on form until a decision is made by the group base on the investigation, no specific guide line on the time frames for removing the sections or performing the recommendations.

Follow up with recommendations “promptly” (after Semi Annual Meeting)

Definition of “promptly” - 1: being ready and quick to act as occasion demands 2: performed readily or immediately

If more data is needed, may require an increase in leakage survey frequency and monitor the indicators.

Recommendations for Suspected “Active Corrosion” Areas can be any of the following: Continue monitoring the Corrosion Indicators and review data at the semi-annual

meeting Update to “Active Corrosion” Status Increase Frequency of Leakage Inspection Apply Cathodic protection or mitigation process Replace pipeline

* Reminder - New Suspected Area of “Active Corrosion” log sheets shall be created for each year, added with any information needed to be passed down from the previous sheet from the previous year. The log book shall retain all the previous sheets from the previous years for historical review for auditing purpose.

The Suspected Area of “Active Corrosion” log sheets can be input by only of the following departments – o Corrosion – Area’s Techniciano Operation’s - designated FOL

But, the individual who entered the information onto the log sheet shall provide data for the next schedule Semi-Annual meeting for the investigation processing.

“Active Corrosion” Areas – DocumentationRecommendation, keep the Area of Suspected “Active Corrosion” log sheets with the Area of “Active Corrosion” log sheets in the same log book.

Nothing should be added to the Area of “Active Corrosion” log sheet with out consensus of the team members involved with the Semi-Annual meeting.

In almost all cases, the Area shall be investigated by placing the segment of pipe into the Suspected Area of “Active Corrosion” as a first step, and then investigated before adding the segment pipeline to the Area of “Active Corrosion” log sheet.

Form C 1282-16, policy and procedure 653-8 exhibit C shall be used for any areas identified as Areas of “Active Corrosion”.

We need to keep in mind, if something is defined as active corrosion, we are applying of fully knowledge of a corrosive area unless controlled could result in a condition that is detrimental to public safety, bottom line, a potential public safety hazard; therefore we should act accordingly.

Once placed onto the Areas of “Active Corrosion” log sheet, there is no investigation work needed, this has been already completed by the Semi-Annual meeting, “meeting of the minds”; only remedial action remains. It can not be removed, unless a follow up of one of the three criteria’s.

One of the three criteria’s shall be listed with a Work order or Job order number. o Cathodically protect the pipeline segment or footage that has been

determined as “Active Corrosion”o Replace the segment or footage that has been determined as “Active

Corrosion”o Retire the segment or footage that has been determined as “Active

Corrosion”

Same as the Suspected Area of “Active Corrosion”, a New Area of “Active Corrosion” log sheet shall be created for each year, added with any information needed to be passed down from the previous sheet from the previous year. The log book shall retain all the previous sheets from the previous years for historical review for auditing purpose and SME meetings, for a period of six years; after this period, the log sheets shall be kept in a central filing system for SME meeting access, if needed. The sheets shall not be discarded at any time; unless approved by the Management team with System Ops and the assigned Area.

Team Work – contributing togetherMeeting of the Minds –

Each department will have a roll into working on completing the process to assure accurate entry into the log books to assure public safety and compliance.
