1. (a)Suspension of APD approval. OCSE will suspend approval of the APD for a Computerized Tribal IV-D System approved under this part as of the date that the system ceases to comply substantially with the criteria, requirements, and other provisions of the APD. OCSE will notify a Tribal IV-D agency in writing in a notice of suspension, with such suspension effective as of the date on which there is no longer substantial compliance.
2. (b)Suspension of FFP. If OCSE suspends approval of an APD in accordance with this part during the installation, operation, or enhancement of a Computerized Tribal IV-D System, FFP will not be available in any expenditure incurred under the APD after the date of the suspension until the date OCSE determines that the comprehensive Tribal IV-D agency has taken the actions specified in the notice of suspension described in paragraph (a) of this section. OCSE will notify the comprehensive Tribal IV-D agency in writing upon making such a determination.
