PD Recommendation Report (PL-SPP-2022-000025)

• A small solar power array to support approximately 10 kilowatts of power (approximately 25-30 panels)to be installed on top of or adjacent to shipping containers. • Underground power lines connecting the satellite and dipole antenna arrays to the shipping containers and solar power array. • Fencing to protect the proposed arrays from grazing animals, enclosing an area of approximately 1 acre. The applicant proposes to clear the 2.0-acre permit area and to install the satellite array at the north end of the site with the dipole antenna array to the south and the catchment tank, shipping containers and port-a-potty located between the arrays. The satellite array is proposed to consist of 1 line of 4 antennas, followed by 2 lines of 3 antennas, for a total of 10 antennas. The pole of each satellite will reach 7 to 8 feet in height, with approximately 25 feet between each satellite. The dipole antennas will be 2 feet in length, fixed to a 1.5-foot post, with approximately 3 feet between each antenna. According to the applicant, the array of satellite dishes would conduct scientific studies on the astrophysical origin of Fast Radio Bursts (FRBs). FRBs are powerful radio bursts coming from within and outside of our galaxy, which are not yet understood. The applicant intends to study the sources and origins of these radio bursts, which requires a "radio-quiet" site. Ka`u was found to be the best radio-quiet area on Hawaii Island, based on surveys conducted by the applicant. The proposed satellites and antennas are designed for FRB reception only, therefore no outward transmission of radio signals would occur. In addition, all satellites would be fixed to look at the northeastern sky only, thus no satellite movement would occur. Finally, the applicant is proposing to operate the facility continuously, however, once operational the facility will typically run unattended, with 1 person checking on operations once or twice a week. The criteria for approving a Special Permit are based on Rule 6-7 in the Planning Commission Rules. It states that the Planning Commission shall not approve a Special Permit unless it is found that the proposed use (a) is an unusual and reasonable use of land situated within the Agricultural or Rural District, whichever the case may be, and(b) the proposed use would promote the effectiveness and objectives of Chapter 205, Hawaii -2-
