NACE 226875 01 11 00 - 3

G. Although attempts have been made to locate and evaluate archaeological sites and/or components prior to construction activities, there is a potential that previously unidentified archeological sites, and components will be identified during construction activities. In the event that construction activities inadvertently discover a previously unidentified archeological site and component the contractor will work cease in the immediate area and notify the contracting officer. Any willful destruction of the archeological site and component can result in the prosecution of individuals under the Archeological Resource Protection Act of 1979 (16 U.S.C. 470), and other statutes that protect the Park’s cultural resources.

1. Reference Section 01 35 13.22 “Archeological Protection” for protection and discovery of resources procedures.

Property and route conditions and surface materials are to be returned to preconstruction conditions or better, at no additional costs to the Government.

N. Landfill: Reference Section 01 35 29 “Health and Safety Plan” for required safety procedures to be taken before intrusive actions within the landfill footprint, due to the explosive nature of the subsurface landfill gas. Landfill gas to be monitored as per the Health and Safety Plan (HASP).
