SQL Server 2008 :: Temp Tables Persisting In TembDB

I've recently started a new position and our production box. Contains a procedure that uses 30 + temp tables. I'm currently not in a position to change this as it's production and I would have to be granted a window to re-design.

However the tempDb is showing some strange activity.

If a table is created #CarrierService (CarrierServiceID,DeliveryZoneID,CollectionZoneID) for example

Once the procedure is called It will appear in the tempDB with the session info appended as expected

#CarrierService________________________________________________________2C78E45A

However once the session has ended the above table will get dropped and a new one created

#2C78E45A, I now have 7000 of these different Tables in the TempDB

When I Interrogate this using

SELECT o.name, o.create_date,o.modify_date , c.Name,C.Column_Id
FROM tempdb.sys.Objects o
Inner join tempdb.Sys.Columns c
ON o.object_id =c.Object_ID
WHERE o.type ='U'

I get the Following results

name create_date modify_date object_id name
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282CarrierServiceId
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282CollectionZoneId
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282DeliveryZoneId

Notice How It's getting Modified today.
