Utility companies are using directional drilling as the preferred method for installing cables, pipelines, conduits, and sewers in urban and suburban communities. Directional drilling can significantly reduce impacts on existing infrastructure, reducing the need for roadway restoration and relocation of other utilities. But there can be significant environmental issues if proper monitoring and contingency plans are not in place. This method uses bentonite and polymer in the drilling mud to lubricate the pipe and stabilize the drilling path. Bentonite can be extremely damaging to wetland, river and creek ecosystems. This session will discuss approaches for identification, containment, and clean-up. Learning Objectives: Create contingency plans for directional drilling projects. Identify, contain, and clean-up inadvertent releases from directional drilling. Design, install and inspect best management practices used in directional drilling.
