As part of Energy Transfer’s (ET) ongoing pipeline integrity program, their operations team is performing maintenance work this week on the casing of the Mariner East pipeline in the area of Lisa Drive. A gel is injected into the casing surrounding the pipeline as part of the cathodic protection maintenance program. There will be no impact to residents during this maintenance work. The work is now completed.
Residents have reached out with several questions regarding the work being completed. Below are those questions along with the answers from Energy Transfer.
- What prompted this work? Answer: This is regular pipeline maintenance and part of our integrity program.
- Has there been some movement of the casing or of the pipe inside, causing an issue or potential issue with cathodic protection? Answer: The pipe is not moving. There are no contaminants inside the casing. There is no concern for public safety. This work is an Energy Transfer standard operating procedure that ensures the pipe within the casing is protected from corrosion. This is an industry best practice and ensures the integrity of the pipeline during operation.
- Are there some contaminants such as water inside the casing that could lead to corrosion? Answer: This work has been completed and the crew will be demobilizing from the right of way over the next couple of days, weather pending.
- This is just one of multiple locations where casing was used for Mariner East in West Whiteland. Is this gel injection going to be done at any others or all of them? Answer: This regular maintenance has been done across the state at a number of locations including previously in West Whiteland Township.
