Permissions

The minimum permission required is ALTER on table_name. TRUNCATE TABLE permissions default to the table owner, members of the sysadmin fixed server role, and the db_owner and db_ddladmin fixed database roles, and are not transferable. However, you can incorporate the TRUNCATE TABLE statement within a module, such as a stored procedure, and grant appropriate permissions to the module using the EXECUTE AS clause. For more information, see Using EXECUTE AS to Create Custom Permission Sets.

MSDN:

If you don't want to grant rights (which are excessive, really, and described in other answers) you can escalate permissions within a stored procedure...

CREATE PROC DoTruncate
WITH EXECUTE AS OWNER
AS
TRUNCATE TABLE Mytable
GO

And permission this instead with "normal" rights
