Four Locks Maintenance Complex Septic System Upgrades
Chesapeake and Ohio Canal National Historical Park » Four Locks Maintenance Complex Septic System Upgrades » Document List
The National Park Service, Chesapeake and Ohio Canal NHP, will replace an antiquated and failing septic system which services the Four Locks Maintenance Complex at Hancock, MD.
In consulation with the Washington County, MD health department, a new state of the art system will be installed. The location of the new system is adjacent to the existing septic tank. The required leach field lines will be installed within disturbed soils. The lines, however, will be installed at a depth of 12 inches below existing grade with top soil overfill. This will eliminate disturbance of archeological resources below the existing fill.
Existing sewer lines will be used with the new system, reducing the overall amount of ground disturbance activites.
Installation will be undertaken by park maintenance staff.
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 #C.8 – Replacement in kind of minor structures and facilities with little or no change in location, capacity, or appearance – for example, comfort stations, pit toilets, fences, kiosks, signs, and campfire circles.
The project also meets the National Historic Preservation Act/Section 106 Programmatic Agreement, Streamlined Review Process #4 – Health and Safety Activities. The project will be monitored by the Cultural Resource Program Manager. The project will not have an adverse effect on cultural resources.
