Narrative:

I had a twin aircraft inbound from the east. I was working south radar position. The aircraft was 10 mi southeast of the airport. I pointed the aircraft out to the control tower for approach on a tight right base entry to runway 5. The aircraft had to stay just south of the departure runway. A printout was necessary. I received approval. Tower called down and asked how close the twin was going to get. I said right there. Next thing I knew, there was a departure coming off the runway. I thought the departure had the arrival in sight. I pointed both aircraft out and they saw each other, but there was no sep before hand. My recommendation is, if you cannot approve something, don't, and don't deviate from standard procedures.
