Last week the Pennsylvania Department of Environmental Protection ordered ETC Northeast Pipeline LLC to identify and restore or mitigate all streams and wetlands that it illegally eliminated or altered during the construction of the Revolution Pipeline, according to a DEP press release.

During the construction of the pipeline, ETC illegally eliminated at least 23 streams by removing and/or filling the stream channels with soil, resulting in a loss of 1,857 feet of stream channel; changed the length of 120 streams by manipulating and/or filling the stream channels with soil, resulting in a loss of 1,310 feet of stream channel; and eliminated at least 17, and altered 70, wetlands by manipulating and/or filling wetlands with soil. The company’s actions were not allowed by the Erosion and Sediment Control General permits or the encroachment permits issued for the pipeline. The company has yet to complete a full assessment of the impact its had on the streams and wetlands along the pipeline’s path.

The DEP has ordered ETC to investigate all of the disturbed areas along the entire length of the pipeline to identify all impacted streams and wetlands. The company will then be expected to implement a plan and schedule to restore the affected areas and monitor the success of the restoration and mitigation thereafter.
