Pennsylvania’s Public Utility Commission ordered the temporary shutdown on Wednesday saying it could have a “catastrophic” effect on public safety if it leaks.
The Pennsylvania Department of Environmental Protection said Sunoco has now demonstrated it can comply with the permit requirements, and regulators will be closely monitoring the work.
DEP directed the company to submit details on how it plans to prevent drilling mud spills – or “inadvertent returns” – that have challenged the project in their dozens since construction began last February.
Sunoco has agreed to halt drilling operations related to the Mariner East 2 pipeline construction in Chester County where several dozen residents have been without water for the past week.
Three environmental groups had appealed to a state Environmental Hearing Board to temporarily block construction on Sunoco's controversial gas pipeline.
Protesters who took to the trees Tuesday are holding steady in their opposition to the construction of a natural gas pipeline through their family's property.
