The THPO is charged with facilitating the Nation's involvement within Section 106 (National Historic Preservation Act of 1966) and Native American Graves Protection and Repatriation Act. These Acts mandate that any ground-disturbing, federally-funded project must first consider its potential impacts to historic properties, cultural resources and/or funerary sites. Additionally, the THPO is consulted for all such off-reservation, aboriginal territorial projects

THPO responsibilities include:

• Government-to-government consultations (agency meetings, site visits and correspondence)
• Project Review and Assessments related to historic properties and cultural resources
• Project-specific mitigation efforts
• On-site mentoring for sensitive sites
• Record keeping and retrieval systems
• Internal and External educational efforts

THPO has successfully provided a Seneca voice in countless projects since its formation and worked with multiple Federal agencies and organizations such as United States Department of Agriculture, Department of Defense, Department of Interior and the Department of Transportation.

THPO short term goals include refinement of the Cultural Resource Management Systems, the development of a Tribal Register for internal and external reference and the continuation of effective government to government consultation concerning Section 102 and the Native American Graves Protection and Repatriation Act. One major long term goal includes preparing for the upcoming Federal Energy Regulatory Commission re-licensing of the First Energy Corporation Power Plant at the Kinzua Dam.
