The USDA’s Animal and Plant Health Inspection Service intends to award a sole source contract for the Cobalt-60 reload of a Foss Therapy Model 484F-C irradiator. Work will be performed at the Phoenix Rearing Facility in Phoenix, Arizona. Foss Therapy Services retains proprietary rights to the equipment’s specifications, but other responsible sources may submit a capability statement for consideration. The government will use responses only to decide whether a competitive procurement is warranted. No budget amount or performance timeline is specified.
