The Phillips 66 Company pipeline maintenance activities for the
identified out-of-service pipeline sections involves several
activities. Each procedure executed is designed to ensure all
potential pipeline hazards have been eliminated. Over the past
10 years Phillips 66 Company with the assistance of AECOM has
performed similar pipeline maintenance activities on over 500
miles of out-of-service pipelines throughout California.
The planned pipeline activities will include:
- Locating and exposing the pipeline at distinct work
locations (6 City of Santa Paula);
- Pipeline tapping and evacuation of fluids;
- Pipeline integrity testing;
- Cleaning the pipeline interior to remove any residual

3-inch pipeline was flushed with water at some point since
water was found in each removed section.
