DTD is beginning 2018 with the three bores for pipeline installation in the Midwest. The crossings trend beneath a small stream and riparian wetland, a short distance upstream of a beaver lodge. As is common in much of the region, obtaining Corps of Engineer permits to trench through the wetland is difficult, and trenching the wetland is damaging to the sensitive ecosystem and is frowned upon.
These HDD borings allow the pipeline to be placed beneath the stream valley and minimize damage to ecosystem. The crossings will be spaced evenly across the ROW and include one 8-inch steel pipeline and two, 4-inch steel pipelines.
The bores enter at the ground a few feet higher than the wetland, pass beneath the wetland, and exit upwards of 80′ high on the opposite valley wall, and almost 600 feet away. Drilling has progressed slowly due to several factors including: winter operations, to the abundance of expansive clay and, perhaps most importantly, our efforts to minimize the risk of discharge of drilling fluid into the wetland or stream.
