3. Section 01 77 00 “Closeout Procedures” for coordinating closeout of the Contract.

1.2 DEFINITIONS

A. Agency with Jurisdiction: An Agency that has been granted legal authority over a location, action, or resource. This authority includes the ability to issue a permit or other legal permission document.

B. Construction Permits – Contractor Provided: Permits obtained by the Contractor based on the means and methods to conduct the work. Construction Permits are typically issued by the Agency to the Contractor and not to the National Park Service (NPS). Examples of typical

Contractor Provided Permits are: NPDES Construction Permit (ground disturbance), dewatering permit, permit for work in a roadway (with traffic management plan), temporary utility tap permit, etc.

C. Government Furnished Permits: Obtained by National Park Service (NPS), usually through the Architect/Engineer (A/E) or a consultant, during the design process (Predesign (PD) through Construction Documents (CD)) and are usually concerned with impacts to resources protected by federal law. However, GF permits can include other permits that are obtained for the convenience of the Government during design. GF permits are "furnished" to the Contractor in the Request for Proposal (RFP) and as part of the final contract documents.

The Contractor must comply with GF permit provisions. Examples of typical GF permits: Clean

Water Act (CWA) 404 dredge and fill permit, CWA Water Quality Certification (often state administered), Highway Right-of-Way Permit, etc.
