The U.S. Environmental Protection Agency (EPA) intends to increase the ceiling of Option Period 1 in the amount of $363,653.36 under GSA T-Mobile USA, Inc. delivery order 47QTCA22D008N/68HERD23F0130, for wireless telecommunication services supporting the EPA's Office of Endpoint & Collaboration Solution Division (ECSD). The purpose of the ceiling increase is to accommodate the increased cellular services needs of the Agency in fiscal year 2025, as well as to account for the incurred trailing costs. • The EPA is seeking to increase the ceiling for Option Period 1 to ensure that all invoices can be paid and that there is no lapse in essential wireless services for the agency. • T-Mobile USA, Inc. is uniquely qualified to continue with the required mobile wireless services to ensure no lapse in services occurs at the EPA. • The EPA is seeking responsible sources to submit bids, proposals, or quotations, which shall be considered by the Agency. • The notice, amendments, and other information related to this NOI requirement will be posted on the Sam.Beta.Gov website at: www.sam.beta.gov.
