The Department of the Interior, through its Interior Business Center (IBC) Acquisition Services Directorate (AQD), is initiating the closeout of contracts that have reached the end of their performance period and have a remaining balance of zero dollars. This action is in accordance with FAR 4.804 and serves as a notification to the vendors listed in the attached contract list, which includes various contractors such as AERO SPRAY INC and AIR RESOURCES HELICOPTERS INC, among others. The closeout process is significant as it ensures the proper conclusion of contractual obligations and financial accountability for the government. Vendors wishing to request a bilateral contract closeout modification or present valid reasons against the closeout must contact Ronald Newlan at ronald_newlan@ibc.doi.gov within ten business days of this announcement.
