What happens if my agency decides to stop using the cloud service offering (CSO)?

Agencies should first notify the cloud service provider (CSP) that they plan to rescind their Authorization to Operate (ATO) as they no longer are using the service. After they have notified the CSP, the agency should send an email to info@fedramp.gov, CCing their CSP, which notifies the FedRAMP Program Management Office (PMO) that the service is no longer in use at the agency, and indicates the agency will rescind the ATO letter by a specific date.
