National Historic Preservation Act


The National Historic Preservation Act (NHPA) requires federal agencies to undergo a review process on impacts to historical and archaeological sites that may be affected by its undertaking.  In accordance with the provisions of NHPA, EPA has determined that the commercial storage of PCBs is an activity that requires a federal permit and therefore is an “undertaking” as defined in 36 C.F.R. S 800.16(y).  Consequently, EPA initiated the Section 106 review process.  The Section 106 review process requires EPA to identify any historic properties that may be affected by operations at Veolia, and to take those historic properties into consideration.

What are Historic Properties?

In the Section 106 process, a historic property is a prehistoric or historic district, site, building, structure, or object included in or eligible for inclusion in the National Register of Historic Places.  This term includes artifacts, records, and remains that are related to and located within these National Register properties.  The term also includes properties of traditional religious and cultural importance to an Indian tribe or Native Hawaiian organization, so long as that property also meets the criteria for listing in the National Register.

The property must be significant, be of a certain age, and have integrity:

  • With regard to significance, is the property associated with:
    • Events, activities, or developments that were important in the past? 
    • Lives of people who were historically important? 
    • Distinctive architectural history, landscape history, or engineering achievements? 
    • Does it have the potential to yield important information through archaeological investigation about our past?
  • With regard to age and integrity, is the property old enough to be considered historic (generally at least 50 years old) and does it still look much the way it did in the past?

A list of historical properties is provided on the National Register website at www.nps.gov/nr/.

Area of Potential Effects

For purposes of this undertaking, the area of potential effects (APE) is the geographic area or areas where the storage and processing of PCBs is authorized under the TSCA Approval, and if issued, the renewal, may directly or indirectly affect historic properties, should they exist.  Veolia currently conducts PCB operations in certain designated areas (warehouse portions of Buildings 2, 3, 4). However, EPA has determined the APE for this undertaking (the area where PCB operations may directly or indirectly affect historic properties) to be the property boundary.
