Superintendent's Compendium Amendment - Masks

The following order, issued by the Superintendent under 36 C.F.R. § 1.5(a)(2), amends the Chesapeake and Ohio Canal National Historical Park Compendium dated September 23, 2021, and posted on-line at https://www.nps.gov/choh/learn/management/index.htm. This order will remain in effect until modified, revoked, or superseded by a subsequent order issued by the Superintendent.

Regardless of vaccination status or local community transmission levels, all individuals over the age of two must wear masks, except when actively eating or drinking, in all common areas and shared workspaces in federally owned buildings administered by the National Park Service and in office space leased by the National Park Service.

'Federally owned buildings administered by the National Park Service' include, but are not limited to, visitor centers, administrative offices, maintenance facilities, and shared government quarters; buildings assigned to concessioners or other park partners; and buildings leased for commercial purposes to individuals or entities other than the National Park Service.

All individuals over the age of two, regardless of vaccination status or local community transmission levels, must wear masks in the following outdoor areas when others are present, except when actively eating or drinking, where the superintendent has determined that physical distancing (staying at least six feet apart) cannot reasonably be maintained:

  • Olmsted Island Trail and Boardwalk at Great Falls, Maryland
  • Billy Goat A Trail at Great Falls, Potomac, Maryland
  • Observation Deck at Great Falls, Potomac, Maryland
  • Carderock Pavilion, Potomac, Maryland
  • Aboard any interpretive vessel including the canal boats at Georgetown, Washington DC and Great Falls, Maryland and the electric touring boats at Williamsport, Maryland
  • All other areas where circumstances may transpire at different times where physical distancing (staying at least six feet apart) cannot be reasonably maintained. For example, a busy parking and boat ramp area on a weekend.

Masks must cover the nose and mouth and fit snugly around the nose and chin with no large gaps around the sides of the face. Masks not designed to be protective, masks with ventilation valves, and face shields do not meet the requirement.

Regardless of vaccination status, all individuals must comply with all orders regarding masks issued by the Centers for Disease Control and Prevention (CDC).

CDC prevention measures continue to apply to all travelers on public transit, regardless of vaccination status. Masks remain required on all forms of public transit that operate within parks, including busses, trains, and boats/ferries, and in transportation hubs.

Park staff should not ask visitors whether or not they have been vaccinated. Absent evidence to the contrary, park staff should operate as though non-masked visitors are fully vaccinated.
