# Presentation: 814952

## API/AOPL Damage Prevention WorkshopJanuary 22, 23 - Houston

- Jennifer Jones
- Buckeye Partners LP
- for API & AOPL

## Goal

- Identify issues
- Excavation Monitoring and Field Practices
- Right of Way Surveillance
- Permanent Signage and Markers
- Discuss Potential Solutions
- Improved procedures
- Industry best practices, standards
- Application of technology(ies)

## Pipeline Markers/Signage

## Marking Liquid Petroleum Pipeline Facilities

- Marking programs are integral parts of operator’s maintenance and emergency plans
- Covers the design (types and materials)
- Addresses minimum marker and sign requirements
- Alternative markers are also covered
- “Recommended Practice” is up for review this year  (every 5 years)

**API RP 1109**

**Notes:**
API RP 1109 is an existing resource for liquid pipeline operators.  Markers and signs indicate the presence of a pipeline facility and warn of the potential hazards associated  with its presence and operation.  As we all know they do not and cannot, as a practical matter,  exactly place the position of a pipeline.  As indicated here, the RP covers minimum marker and sign requirements.  It also makes recommendations on alternative markers for certain areas under certain conditions.
 API RP’s and standards are reviewed for their continued relevance and accuracy every five years.  RP 1109 is up for review and a work group is beginning work on it now.

## API RP 1109 

- Mentions several instances where additional/alternative
- markers may be appropriate:

- Sides of roadways
- Railroad crossings
- Fence lines
- Property lines
- Right-of-way boundaries
- Water crossings

- Above ground crossings
- Intermediate markers in
-  areas of high activity
- 2 markers visible from
-  any location along
-  pipeline

**Notes:**
In some locations under certain conditions, alternative markers may be appropriate.  Consideration should be given to the consequences of a pipeline failure; the nature of the commodity being transported; and proximity to different land uses (commercial, residential, etc.) 

## Slide 6

## Pipeline Markers/Signage

- Recommendations
- Research the effectiveness of signs in different environments
- Research the effectiveness of various symbols address bi-lingual needs
- Modify API 1109 and CGA Best Practices accordingly

**Types Of ROW Markers Used**

## Pipeline Markers/Signage

- Recommendations
- Research stats on what really gets attention
- Focus groups
- Affected Public
- Emergency Responders
- Excavators
- Universal symbolic language – all cultures
- Should be addressed by RP 1109 Committee

**Marker Content**

## Pipeline Markers/Signage

- Recommendations
- Research line of sight effectiveness
- CGA should consider a best practice after research is conducted
- Develop a standard for what ‘line of sight’ means
- Modify RP 1109 to include explanation of ‘line of sight’
- Modify RP 1109 Section 2.1.2 (alternate markers)

**Marker Spacing and Criteria**

## Pipeline Markers/Signage

- Recommendations
- Draft guidelines and develop best practices to address
- 	marker verification through:
- Aerial patrol
- Mowing
- On the ground survey
- Cathodic protection survey
- Mainline valve inspections
- Depth of cover survey
- Close interval survey
- Maintenance projects/new projects
- Routine line locates
- GPS

**Marker Verification**

## Pipeline Markers/Signage

- Recommendations
- RP 1109 Committee should consider addressing making CGA and RP 1109 consistent concerning marker locations
- RP 1109 Committee should address recommendations for issues with residential properties
- Removal of markers
- Beautification ordinances

**Marker Location**

## Pipeline Markers/Signage

- Recommendations
- Research is needed to determine the
-     effectiveness of signs

**Road Markers**

## Pipeline Markers/Signage

- Abandoned Pipelines
- Need to review and address
- Look to CGA for guidance

**Additional Issues/Recommendations**

## Pipeline Markers/Signage

- Research effectiveness of:
- Signs
- Messages
- Symbols
- Marker locations
- Frequencies in various environments
- Modify API 1109 and CGA Best Practices accordingly

**Summary of Recommendations**

**Notes:**
These were the highest ranked recommendations for markers and signs and will be considered as RP 1109 is reviewed.  

## Pipeline Markers/Signage

- Modify RP 1109 to include explanation of ‘line of sight’
- Modify RP 1109 Section 2.1.2 to eliminate ROW and property markers
- CGA develop guidance on marking of
- 	abandoned pipelines

**Summary of Recommendations**

**Notes:**
We will also pass the last recommendation on to CGA.
