The PI should prepare a letter, signed by the PI and then co-signed by the OGRD Director, addressed to the USDA Program person which indicates that WSU is relinquishing the award. The letter should be accompanied by a memo communicating that you will be transferring the grant to the new institution and should include the Chair and Dean's approval for the transfer. Once all the charges have cleared, SPFO will fill out the form send it back to OGRD to include with the relinquishment letter. The OGRD will co-sign the relinquishment letter and forward it to the Program Officer and the Grants Specialist at USDA that is outlined in the latest Grant Award. This simply transfers the grant and not any equipment.
Transfers can often take a great deal of time so the clearing of expenditures early is very helpful.
It is also important to be in contact with the Program Officers at USDA to communicate your intentions.
