Pennsylvania Halts Construction of Mariner East 2 Pipeline
Statement from Andrew Williams, Director of Regulatory and Legislative Affairs
The Pennsylvania Department of Environmental Protection issued an order to suspend construction of the Mariner East 2 Pipeline, which is linked to water contamination in multiple counties.
“Governor Wolf and the DEP made the right call. This action proves that irresponsible companies can no longer pollute without consequence. Continued vigilance from the Wolf Administration will be critical to protect Pennsylvanians’ air and water and to ensure all oil and gas companies operate more responsibly within the commonwealth.”
