HubLine/East to West Expansion

Algonquin retained PAL in 2007 to manage and coordinate all cultural resource management responsibilities for the HubLine/East to West Expansion Project (FERC Docket #CP08-420-000).

These services, completed under Federal Energy Regulatory Commission (FERC) guidelines and Section 106 of the National Historic Preservation Act, included archival research, field investigations, and data analyses for rights-of-way spanning more than 50 miles and dozens of ancillary facilities in Massachusetts, Rhode Island, Connecticut, and New Jersey.

Process & Results

  • Owing to our experience and presence in this market, PAL assists Algonquin by anticipating and addressing the unique issues that arise during the planning, permitting, and construction of pipeline projects. PAL developed standardized procedures for archival research, sensitivity assessments, documentation, and subsurface testing to efficiently examine large-scale linear project areas.
  • In consultation with four State Historic Preservation Officers, eight Native American tribes, and 29 local historical commissions, PAL completed archaeological and historic architectural properties identification surveys and site evaluations.
  • In Connecticut, PAL surveyed approximately 15 miles of pipeline resulting in the identification of 22 archaeological sites, 109 historic stone walls, and 15 historic architectural properties. In Massachusetts, PAL surveyed more than 30 miles of pipeline, resulting in the identification of 58 archaeological sites, 15 historic stone walls, and 241 historic architectural properties.
  • Of the 80 archaeological sites identified in Connecticut and Massachusetts, 21 were considered potentially eligible for listing in the National Register of Historic Places. PAL subsequently conducted site evaluation investigations at 14 sites to evaluate their potential for listing in the National Register.
