Public Notice Announcing Implementation of Section 106 Programmatic Agreement

Agency: U.S. Department. of the Interior, Bureau of Reclamation

Action: Implementation of National Historic Preservation Act (NHPA) Compliance – Programmatic Agreement (PA) document

Summary: Reclamation is providing public notice of a PA with the Central Oregon Irrigation District (COID) and the Oregon State Historic Preservation Office (Oregon SHPO). The PA identifies the procedures we will use to comply Section 106 of the NHPA when Reclamation funds canal piping projects or other improvements to COID’s water management infrastructure.

For Further Information contact: Gregg Garnett, Bend Field Office manager, at 541-389-6541 ext. 226; 1375 SE Wilson Ave. #100, Bend, Oregon 97702-2607; Questions for COID may directed to

Supplementary Information: Reclamation, COID, and the Oregon SHPO have developed a PA in accordance with 36 CFR 800.14(b) to streamline Section 106 compliance responsibilities when federal grant funds are awarded or issued by Reclamation to COID for water and energy conservation projects, such as canal piping.

In 2014, Reclamation, COID and Oregon SHPO agreed to prepare this PA in a Memorandum of Agreement (MOA). The MOA outlined several stipulations – of which the PA is one – the parties would take to mitigate for adverse effects previous piping projects had on historic properties.  The other stipulations included a reconnaissance level survey of COID’s irrigation system, a Multiple Property Document (MPD), nomination to the National Register of Historic Places of segments of the Pilot Butte and Central Oregon canals, and development of interpretive signage at the nominated segments.  Together, these other stipulations document the role COID’s facilities played in the history of Central Oregon and provide interpretive opportunities to the public to learn about this history.

The PA identifies how the parties will comply with Section 106 of the NHPA when Reclamation provides funds to COID in the future.

  • Evaluates whether features and segments of COID’s system that have not been evaluated contribute to the eligibility of the Central Oregon Project or are individually eligible for listing in the national register. If a feature or segment is individually eligible, the PA provides procedures to address potential adverse effects to those features or segments;
  • Identifies routine and minor COID activities that would have “no effect” or “no adverse effect” to historic properties, and would not require Section 106 review;
  • Provides protocols for addressing inadvertent or unanticipated discoveries of cultural resources, and addressing emergency situations or eminent threats of damage; and
  • Establishes procedures for the preservation of National Register-listed features within the COID system.

The PA also allows for other federal agencies who might fund or approve similar activities within the COID system to join the agreement.

This agreement document will be available for review after February 8, 2019, at:


Initiated in 2009, the Deschutes Basin Habitat Conservation Plan (DBHCP) is a plan that will be used by the City of Prineville and the eight Irrigation District members of the DBBC to meet their current and future water needs while enhancing fish and wildlife habitat. The City and Districts determined they would produce a more comprehensive Plan by working together rather than individually. You can read an update on the plan by clicking on the link below.
