Brunswick CSX Contamination Monitoring Well Permit

Chesapeake and Ohio Canal National Historical Park » Brunswick CSX Contamination Monitoring Well Permit » Document List

The National Park Service, Chesapeake and Ohio Canal NHP, received an application for a construction permit to install 10' deep geo-boring monitoring wells within Mile 54 of the park. This area of the park has been monitored for over a decade for underground contamination that resulted from fuel oils on the adjacent CSXT Rail yard at Brunswick, MD. Existing long-term monitoring wells have been providing information on the migration of contaminants within park boundaries. The current project would install 30 temporary geo-boring wells to provide further data on the contamination. Additionally, one of the long-term wells (NPS MW-11) will be replaced as it has ceased to function.

The project will involve three sites within the canal prism, each to have ten geo-borings. Two of the borings within each site will be used for a short term water monitoring well. Upon completion of the evaluations, the holes will be backfilled with bentonite.

All drillings for the canal prism geo-borings will be accomplished from the park towpath. The towpath will remain open for use during the project. The project is expected to take approximately one week.

The one existing long-term well to be replaced will be in close proximity to the existing, which is located on the berm of the canal. The installation of that well will be accomplished from the CSX access road. The existing well #11 is not readily visible. If located, a certified well driller will close it off with backfilling with bentonite.

Additionally, some minor repairs to existing wells will be made. The repairs will include lock/hinge work.

A special use permit will be issued for the construction and associated monitoring work. In addition to the park towpath remaining open, some minor vegetation removal will be reviewed and approved by park natural resource staff. Additionally, Site #1 contains historic culvert #86. All geo-borings near the culvert will need to remain 25 feet away from the culvert's center line.

It will be incumbent on the project applicant to contact Miss Utility or another certified inspector to provide information on any underground utilities within the area.

The park's Interdisciplinary Team reviewed the project for impacts to natural and cultural resources. The project does not pose any serious or long-term effects to the environmental, historical, cultural, archeological, or visual resources. It meets categorical exclusion # E.5 Nondestructive data collection, inventory (including field, aerial, and satellite surveying and mapping), study, research, and monitoring activities.

The project also meets the National Historic Preservation Act/Section 106 Programmatic Agreement, Streamlined Review Criteria #4 – Health and Safety Activities.
