New Design Raw Water Main and McKinney Treated Effluent Outfall

Chesapeake and Ohio Canal National Historical Park » New Design Raw Water Main and McKinney Treated Effluent Outfall » Document List

The National Park Service (NPS) has completed the environmental review process to analyze impacts associated with the construction of a proposed raw water main and treated effluent outfall by Frederick County, Maryland. The review was conducted in accordance with the National Environmental Policy Act and Section 106 of the National Historic Preservation Act. The resulting environmental assessment looked at potential impacts to natural and cultural resources of the Chesapeake and Ohio Canal National Historical Park.

The environmental assessment was released for a 30 day public review between November 1 and November 30, 2006. A public meeting was held on November 15, 2006. Public comments were received and analyzed for substantive comments. These comments were forwarded to National Park Service managers for consideration in the decision making process.

A Finding of No Significant Impact (FONSI) has been finalized for the project. A copy of the FONSI is available on this website under "Document List."

Frederick County, Maryland currently operates a water intake and treated effluent outfall at Nolands Ferry. The project will upgrade the infrastructure between the raw water intake, at the Potomac River, and the New Design Treatment Plant. The majority of the work, within the boundaries of the park, will be within the existing right-of-way. The selection of Alternative 3 from the Environmental Assessment as the preferred alternative will increase the right-of-way requirements to an additional 0.25 acres. This additional acreage, for the right-of-way, will allow the pipeline to be constructed further away from the existing roadway underpass. Concerns from CSX Railroad managers were expressed as a result of the environmental assessment review. Their concerns were that the new construction could compromise the structural integrity of the roadway underpass. Therefore, they requested to have the new pipelines installed further away from the underpass to protect both motorists and train traffic. Additional archeological investigations and natural resource investigation yielded that this request would not pose any impacts to park resources.
