# WF-004-EPOC - Notification / No Ground for Refusal / Emergency EPOC
**Workflow Description:** Request-reply workflow for obtaining traffic data and /or content data, where offence or data subject are not in the issuing state. Emergency EPOC. No ground for refusal is being considered.
Same message exchange as in [WF-001-EPOC](WF-001-EPOC.md), except that:
- SP has 8 hours to provide the requested data instead of 10 days.
- SP can release the resources allocated after 96 hours, which is the time alloted to EA to raise grounds for refusal.
