Pennsylvania is halting construction permits for natural gas pipelines operated by Texas-based Energy Transfer LP, as the governor on Friday said the company has failed to respect the state’s laws and communities.The state Department of Environmental Protection said Energy Transfer is not fixing problems related to an explosion last year, and piled yet another penalty onto a company project in the state.State agencies already have imposed millions of dollars in fines and several temporary shutdown orders on Energy Transfer projects, while a county prosecutor is demanding documents from the company.
