Notice of Intention to Modify Natural Precipitation

The ARB has requested publishing of the legal notice below regarding the North Dakota Cloud Modification Project in the county newspapers of the NDCMP target area and adjacent counties. These newspapers include Adams County Record, Billings County Pioneer, Bowman County Pioneer, Burke County Tribune, Dunn County Herald, Golden Valley News, McKenzie County Farmer, McLean County Independent, Minot Daily News, Mountrail County Promoter, Mouse River Journal, Renville County Farmer, The Herald (Slope & Hettinger Counties), The Journal (Divide County), and the Williston Herald. The last publishing date by these newspapers was Friday, March 10th. Therefore, the 20-day comment period will end on March 30th, 2017.

Notice is given, that Weather Modification, LLC of 3802 20th Street North, Fargo, ND, a licensee (License No. 2017-1) of the State of North Dakota, is to engage in operations to modify precipitation by the addition of ice nucleating agents in the counties of Bowman, Burke, McKenzie, Mountrail, Ward and Williams and seven townships in Slope County. Existing clouds will be selected for seeding according to the current operational procedures for enhancing rainfall and decreasing hail damage. Nuclei will be generated by silver iodide produced in the combustion of flares or acetone solutions, and the dropping of dry ice pellets. Twin-engine aircraft equipped for instrument flight operating under FAA airworthiness certificates and licensed by the North Dakota Aeronautics Commission will accomplish all seeding.

The operations area will include the target area and a buffer zone ten miles in width surrounding the target area in adjacent North Dakota counties. Seeding operations in the buffer zone is for cloud systems that may affect the target area. No effect is intended for the buffer zone. The target area for District I will be Bowman County and the following townships in Slope County: Conner, Hume, Carroll, Cash, Sheets, Mineral Springs, and Cedar Creek. The target area for District II will be Burke, McKenzie, Mountrail, Ward and Williams Counties. Operations will be conducted June 1, 2017 through August 31, 2017, with the possibility of extension through October 2, 2017.

All persons who think they may receive harm from activities of this project should write the Director, North Dakota Atmospheric Resource Board, 900 East Boulevard Avenue Department 770, Bismarck, ND 58505-0850 or email Darin Langerud. Comments must be received within 20 days of the last date of publication of this notice.
