NOAA intends to award a sole-source purchase order to Aerial Associates Photography Inc. for hyperspectral imaging flights to detect harmful algal blooms in Lake Michigan, Lake Erie/Lake St. Clair, and Lake Huron. The period of performance is from the date of award to December 30, 2026. The justification is that the vendor is uniquely equipped with a modified aircraft capable of mounting the government's sensor and can respond on short notice. Firms believing they can meet the requirements may submit substantiating documentation to the point of contact within 15 days of this notice's publication for a potential competitive determination.
