The Montana Department of Environmental Quality (DEQ) is seeking public comment and holding a remote public hearing on the tentative determination to issue a Water Quality Certification for the Keystone XL Pipeline project in eastern Montana under section 401 of the Clean Water Act.

The project requires a water quality certification because the pipeline would cross 201 wetland and water body features that are regulated under the Clean Water Act. A 36-inch diameter pipeline would be installed at water body crossings by creating an open, dry trench ​or by drilling under those water bodies. The open-cut, wet method of constructing stream crossings is not allowed if water is present at the time of construction. For specific rivers, the applicant would drill under the water bodies to avoid water quality impacts—those rivers are the Milk, Missouri and Yellowstone. The crossings are located in the following Montana counties: Phillips, Valley, McCone, Dawson, Prairie and Fallon.
