      CHAPTER I--NATIONAL PARK SERVICE, DEPARTMENT OF THE INTERIOR
 
PART 68_THE SECRETARY OF THE INTERIOR'S STANDARDS FOR THE TREATMENT OF 
HISTORIC PROPERTIES--Table of Contents
 
Sec.  68.2  Definitions.

    The standards for the treatment of historic properties will be used 
by the National Park Service and State historic preservation officers 
and their staff members in planning, undertaking and supervising grant-
assisted projects for preservation, rehabilitation, restoration and 
reconstruction. For the purposes of this part:
    (a) Preservation means the act or process of applying measures 
necessary to sustain the existing form, integrity and materials of an 
historic property. Work, including preliminary measures to protect and 
stabilize the property, generally focuses upon the ongoing maintenance 
and repair of historic materials and features rather than extensive 
replacement and new construction. New exterior additions are not within 
the scope of this treatment; however, the limited and sensitive 
upgrading of

mechanical, electrical and plumbing systems and other code-required work 
to make properties functional is appropriate within a preservation 
project.
    (b) Rehabilitation means the act or process of making possible an 
efficient compatible use for a property through repair, alterations and 
additions while preserving those portions or features that convey its 
historical, cultural or architectural values.
    (c) Restoration means the act or process of accurately depicting the 
form, features and character of a property as it appeared at a 
particular period of time by means of the removal of features from other 
periods in its history and reconstruction of missing features from the 
restoration period. The limited and sensitive upgrading of mechanical, 
electrical and plumbing systems and other code-required work to make 
properties functional is appropriate within a restoration project.
    (d) Reconstruction means the act or process of depicting, by means 
of new construction, the form, features and detailing of a non-surviving 
site, landscape, building, structure or object for the purpose of 
replicating its appearance at a specific period of time and in its 
historic location.
