The Mariner East 1 pipeline sprung a leak on April 1st, 2017.  The leak was from an 8-inch steel pipe.  The pipeline was shut down, and repairs carried out over the course of several days.

It was a small leak, just 20 barrels of ethane and propane.  No one was injured, and no water was contaminated.

It’s important to note that the company “was informed of the leak”.  Makes it sound like someone other than the company was responsible for discovering the leak.

This is the first pipeline leak we’ve run across this month.  While it’s small, it’s important because people need to know that pipelines leak and that the company doesn’t usually discover the leaks, especially when they’re “small”.  The safety technology they use doesn’t detect the small stuff well.
