Dakota Access developer’s new pipeline rankling regulators

NEW WASHINGTON, Ohio — The company that developed the Dakota Access oil pipeline is entangled in another fight, this time in Ohio, where work on its multi-state natural gas pipeline has wrecked wetlands, flooded farm fields, and flattened a 170-year-old farmhouse.

The federal commission that oversees gas pipelines told Dallas-based Energy Transfer Partners last week to clean up its mess before it will allow the Rover Pipeline to flow. New drilling on unfinished sections also remains halted after 2 million gallons of drilling mud seeped into a wetland in the spring.

While the $4.2 billion pipeline that will carry gas from Appalachian shale fields to Canada and states in the Midwest and Gulf Coast hasn’t been besieged by protests that erupted in North Dakota, opponents say the spills and snags highlight the risks that come with building huge pipelines needed for expanding the natural gas and oil industries.

Much of the 700-mile Rover Pipeline is being built across Ohio and will extend into Michigan, Pennsylvania, and West Virginia.

Ohio’s environmental regulators and landowners say construction crews have been laying pipe at warp speed since March to meet the company’s ambitious plan of finishing the first phase this month and the entire project by November.

‘‘As soon as they started, they began having problems,’’ said Craig Butler, director of Ohio’s Environmental Protection Agency. ‘‘It’s just a function of them moving too quickly, trying to meet a deadline and cutting corners.’’

The state EPA has proposed nearly $1 million in fines over violations that include allowing drilling mud to spill into wetlands, ponds, and streams along with pumping storm water into streams and fields. Most of the violations were in March and April but some problems continue.

Just last week, the Federal Energy Regulatory Commission ordered Energy Transfer Partners to clean up and restore 6 acres of wetlands coated with more than a foot of drilling mud, remove mud contaminated with diesel fuel from two quarries, and monitor water wells near those sites.

The federal agency is continuing to investigate and could issue more orders. It also accused the company of not being truthful about its intention to demolish a 170-year-old farmhouse that stood in the pipeline’s path.

Energy Transfer Partners later agreed to pay $3.8 million to Ohio’s historic preservation efforts for knocking down the house last year.

The company now is working to comply with regulators on the cleanup orders, said spokeswoman Alexis Daniel. But doing that will delay completing the pipeline’s first phase until later this summer, she said Wednesday.

‘‘Our pipelines are always constructed to the highest standards, so I would unequivocally deny any assertion to the contrary,’’ Daniels said.

In Michigan, the state’s two US senators want federal regulators to pause construction and consider moving the path of the pipeline away from a popular lake and summer camp for children.

Dozens of Ohio farmers have complained that their fields have been flooded after heavy rains by crews pumping storm water out of open trenches. Some have asked a federal judge to tell the company to stop doing it, arguing it violates their land agreements.

Those agreements compensate the owners for putting the pipeline on their land, but farmers say it doesn’t give the company the right to flood their adjacent land. Energy Transfer Partners said it has been dealing with unprecedented rainfall and is trying to avoid and minimize impact on crops.
