(doing business as Rocky Mountain Air Solutions), for the weekly delivery of liquid nitrogen and carbon dioxide (CO2) to the CDC Fort Collins facility. The product/service the Government is seeking is essential for maintaining the integrity and viability of samples, which require cryogenic storage at temperatures of -140°C. The cryogenic refrigeration necessary for our materials is uniquely provided by liquid nitrogen and CO2 gases. Other refrigeration methods do not achieve the ultra-low temperatures required to preserve these sensitive samples, making them unsuitable for the Government needs. The nature of the work demands just-in-time delivery to ensure that the cryo freezers remain operational. Local suppliers are essential to meet these urgent delivery requirements. This contract action is for supplies and services for which the Government intends to solicit and negotiate with only one source under the authority of Revolutionary FAR Overhaul 12.102, 41 USC 1901, Unusual urgency. This notice of intent is not a request for competitive quotations; however, all quotations/responses received by the response date listed in this notice, shall be considered by the government. A determination by the government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. Any quotation/response should be emailed to the Ann Bonis, Contracting Officer at won5@cdc.gov by Friday November 6, 2026, 4:00 pm ET. ## Publications - November 3, 2026: Special notice, due November 6, 2026 at 4:00 PM EST.
