TAX MAP KEY (TMK) Number: TMK (1) 9-1-031:001 (por.) & 028

Notice is hereby given that the Honolulu Board of Water Supply (BWS) proposes construction of a desalination
facility in Kalaeloa, O’ahu, Hawai’i. The U.S. Bureau of Reclamation (USBR) is providing grant funding to the
BWS for construction of the project. This federally funded BWS project is considered a federal action and
undertaking, as defined by Section 106 of the National Historic Preservation Act (NHPA).

The project will include installation of reverse osmosis treatment equipment, enclosed buildings to house the
equipment, and an administrative office. Initial construction will be sized for a 1.7 million gallons per day (MGD)
treatment facility with potential for future expansion. Roads will be constructed on the property to provide
access throughout the facility. An aerobic wastewater system and leach field for domestic wastewater treatment
is planned as part of the facility. The facility will be located on the northeast portion of BWS-owned parcel TMK
(1) 9-1-031:028. The Area of Potential Effect (APE) includes the entirety of this parcel.

Other improvements include installation of underground water lines and overhead powerlines along ‘Ola’i Street.
Two underground injections wells are planned along ‘Ola’i Street and will be used to dispose brine concentrate
from the reverse osmosis process. Water line, power line, and injection well improvements will be located on a
portion of State-owned parcel TMK (1) 9-1-031:001. The APE includes a corridor for construction of the utility
lines and injection wells.

Pursuant to Section 106 of the NHPA, Native Hawaiian organizations and Native Hawaiian descendants with
ancestral lineal or cultural ties to, cultural knowledge or concerns for, and cultural or religious attachment to
the proposed project area, or other individuals and organizations with legal, economic or historic preservation
interest who would like to participate in the Section 106 process for the proposed project are requested to
contact Mr. Dominic Dias, Civil Engineer VI, BWS Water Resources Division, via email at or by
